<p><a href=
  "https://invisible-island.net/xterm/xterm.log.html">Here</a> is
  the latest version of this file.</p>

<p>It began as a list of the changes that I made for xterm, using
  the notes that I added when submitting a patch. You should note
  that other changes were made as well, by other people, to fix
  bugs and correct ifdef's for portability. Until mid-2006, most of
  these were summarized in the XFree86 <a href=
  "https://web.archive.org/web/20070101220948/http://cvsweb.xfree86.org/cvsweb/xc/programs/Xserver/hw/xfree86/CHANGELOG">
  CHANGELOG</a>).</p>

<h1><a name="xterm_353" id="xterm_353">Patch #353 -
  2020/02/01</a></h1>

<ul>
    <li>amend change in <a href="#xterm_352">patch #352</a> for
    button-events to fix a case where some followup events were not
    processed soon enough (report/patch by Jimmy Aguilar
    Mena).</li>

<li>handle <em>MappingNotify</em> X event, to improve recovery
    when switching keyboard configurations using
    <code>xkbcomp</code> (prompted by discussion with Frank Mosch,
    Debian #661295). There is more work needed here, possibly in
    the X libraries.</li>

<li>improve discussion of mouse-mode in <code>ctlseqs.ms</code>
    (suggested by Igor van den Hoven).</li>

<li>further improve checks for Xft <em>max-advance-width</em>
    to take into account fonts which use two cells for ambiguous
    width characters. Also improve the time used for these checks
    (reports by Yuri Pankov, Frank Mosch).</li>

<li>fix a few spelling errors reported by codespell (report by
    Jens Schleusener).</li>

<li>modify <code>run-tic.sh</code> to prefer development
    version of ncurses since changes to terminfo file in <a href=
    "#xterm_345">patch #345</a> rely upon bug-fixes in ncurses
    (prompted by discussion with Will Senn).</li>
  </ul>

<h1><a name="xterm_352" id="xterm_352">Patch #352 -
  2020/01/16</a></h1>

<ul>
    <li>adjust fontsize data to handle a minor inconsistency from
    recent Xft versions (Debian #880407, adapted from patch by
    Vincent Lefevre).</li>

<li>add a table to the manual page description of
    <code>forceBoxChars</code> to alert the reader to the special
    characters aside from &ldquo;line-drawing&rdquo; which are
    drawn directly when this resource is set (Debian #931305).</li>

<li>improve <code>checkXft</code> logic which attempts to
    detect fonts whose <em>max-advance-width</em> is inconsistent
    with the actual glyph widths. For some fonts, it is necessary
    to check additional characters (report/analysis by Jan
    Engelhardt).</li>

<li>improve configure-checks for X headers and libraries on
    recent MacOS, which has moved those files under
    <code>/usr/X11</code>.</li>

<li>improve portability of iconify/deiconify feature by taking
    into account some window managers which manipulate the EWMH
    <code>_NET_WM_STATE</code> property, adding/removing
    <code>_NET_WM_STATE_HIDDEN</code> rather than actually
    <em>minimizing</em> the window (prompted by discussion with
    J&ouml;rg Breitbart).</li>

<li>improve workaround from <a href="#xterm_287">patch #287</a>
    for the <code>-iconic</code> option when configured with
    toolbar by postponing the extra request for minimizing the
    window to the end of menu-initialization.</li>

<li>modify <code>xevents</code> special-case for mouse-events
    to include button-events so that the meta key by itself can
    generate button-events (report/analysis by Mattias
    Engdeg&aring;rd).</li>

<li>amend SGR-stack change from <a href="#xterm_348">patch
    #348</a> to not associate bold attribute with background color
    (report by Nicholas Marriott).</li>

<li>fix copy/paste error in manual page (patch by Larry
    Hynes).</li>

<li>add definitions in <code>xterm_io.h</code> so that GNU/Hurd
    will use <code>posix_openpty</code> (patch by Samuel
    Thibault).</li>

<li>build-fix in debug-tracing, for <code>esctest</code>.</li>

<li>updated autoconf macros</li>

<li>update config.guess</li>
  </ul>

  2019/11/17</a></h1>

<ul>
    <li>correct logic in <code>property_to_string</code> for
    deciding when to fallback from UTF-8 decoding to ISO-8859-1
    decoding, broken in <a href="#xterm_350">xterm #350</a>
    (FreeBSD #241961).</li>

<li>add <code>-report-icons</code> to help-message.</li>

<li>improved autoconf macros:

<ul>
        <li><code>CF_ADD_LIBS</code>: the change to filter out
        duplicates caused this to append rather than prepend.
        revise to fix that.</li>

<li><code>CF_GCC_VERSION</code> and
        <code>CF_GCC_WARNINGS</code>: move checks to distinguish
        icc/clang from gcc from the macro which handles the
        --enable-warnings option, to make this work
        without-warnings for the inline-checks.</li>
      </ul>
    </li>

<li>update config.guess, config.sub</li>

<li>correct status in <code>XTGETXRES</code> replies when the
    resource was not found.</li>

<li>fix some gcc, cppcheck, clang and coverity warnings.</li>

<li>guard call to <code>RequestResize</code> from the
    struct-notify event handler to prevent recursion in the
    Xft+buffered workaround in some cases when doing manual
    resizing rather than resizing via escape sequences (reports by
    Stefan Assman, Mike Thornburg).</li>

<li>amend the workaround for Xft+buffered blanking by moving
    the switch to bitmap-fonts to account for differences in font
    metrics between bitmap- and TrueType-fonts (report by Stefan
    Assmann).</li>

<li>improve the note on the <code>xterm-rep</code> terminfo
    entry (prompted by discussion with Sven Joachim).</li>
  </ul>

<h1><a name="xterm_350" id="xterm_350">Patch #350 -
  2019/11/02</a></h1>

<ul>
    <li>modify html/svg dump to not ignore zero'd/blank cells.</li>

<li>align terminfo file with ncurses, e.g., add
    <code>xterm+osc104</code> block.</li>

<li>improve discussion of <code>modifyOtherKeys</code> in
    manual page and in <code>ctlseqs.ms</code>.</li>

<li>add <code>vttests/modify-keys.pl</code> script to
    illustrate the <code>modifyOtherKeys</code> resource (prompted
    by discussion with Bram Moolenaar).</li>

<li>various improvements to <code>ctlseqs.ms</code>, as part of
    autogenerating links for the website.</li>

<li>update manual page default for <code>saveLines</code>
    resource default value (Branden Robinson, Debian #913815).</li>

<li>add command-line option <code>-report-xres</code> to show
    the values of the VT100 widget X resources when initialization
    is complete.</li>

<li>add a control sequence which, like tcap-query, allows an
    application to inspect most X resource settings of the VT100
    widget.</li>

<li>adjust some optional features to enable them in the imake
    configuration as they would be by default via the configure
    script.</li>

<li>add null-pointer checks to improve error recovery when
    bitmap fonts are missing or corrupt (report by Jonne
    Ransijn).</li>

<li>correct the condition for deleting the EWMH window-title
    property, i.e., if UTF-8 titles are disabled, rather than if an
    update to the EWHM property found no change (report by Sven
    Joachim).</li>

<li>build-fix for the case when configure
    <code>--enable-trace</code> is used without
    <code>--enable-warnings</code> (report by Sven Joachim).</li>

<li>fix a few minor bugs found with Coverity.</li>

<li>add a check in <code>property_to_string</code> to avoid
    translating <code>UTF8_STRING</code> or
    <code>COMPOUND_TEXT</code> into Latin-1 when UTF-8 encoding is
    active, e.g., when pushing onto the title-stack while switching
    to the alternate screen.</li>

<li>build-fix for the <code>--disable-doublechars</code>
    configure option (report by Brian Lindholm).</li>
  </ul>

<h1><a name="xterm_349" id="xterm_349">Patch #349 -
  2019/09/22</a></h1>

<ul>
    <li>add graphic context to support bold+italics (patch by Quinn
    Strahl).</li>

<li>document window properties in the manual page.</li>

<li>improve title-string feature:

<ul>
        <li>if any of <code>allowC1Printable</code>,
        <code>utf8Title</code> or <code>titleModes</code> hint that
        an application might send a title-string encoded in UTF-8,
        check if that is the case, and if it is recodable into
        ISO-8859-1, use that for the ICCCM-style title.</li>

<li>check if the title given by a control sequence happens
        to be already encoded in UTF-8, to avoid double-encoding
        (FreeBSD #240393).</li>

<li>Make <code>sameName</code> resource work for the EWMH
        titles.</li>

<li>Modify menu-state of <code>utf8Title</code> to be
        consistent with the <code>utf8</code> source, i.e., setting
        the EWMH properties automatically when UTF-8 is
        active.</li>
      </ul>
    </li>

<li>reorganize text-drawing to make it possible to investigate
    using Xft to implement VT100-style double-sized characters.
    While doing this, made a workaround for apparent Xft bug which
    loses its drawable state when switching from 132 to 80
    columns.</li>

<li>improve font-warning messages by showing which are
    <em>derived</em> rather than directly from resource settings
    (suggested by Tomas Korbar). Also filter repeated font-warning
    messages, to accommodate broken X configurations.</li>

<li>fix an inconsistency between failure to load derived wide
    font versus failure to load derived wide-bold font (Redhat
    #1679790). That relies upon the &ldquo;:unscaled&rdquo;
    property which is broken in some distributions (however, recent
    Debian and the BSDs such as MacOS work).</li>

<li>updated autoconf-252 to check X11R7 include/lib directories
    found on some older configurations.</li>

<li>set a graphic-context for border when double-buffering is
    active; to prevent the border color from changing when
    switching to reverse-video.</li>

<li>build-fix for <code>--disable-ziconbeep</code>, which
    conflicted with the new double-buffer configuration (report by
    Brian Lindholm).</li>

<li>fix loop-limit for lookup of <code>fullscreen</code>
    resource broken in <a href="#xterm_347">xterm #347</a> (report
    by Scott Bertilson).</li>

    (Debian #932569, patch by Jonathan Irwin).</li>

<li>fix a misformatted printf in
    <code>report-sgr.pl</code>.</li>

<li>add configure check for termios types, to improve
    compiler-warnings.</li>

<li>ensure that when resetting margins, to also reset
    <code>DECLRMM</code>. This affects <code>DECCOLM</code>,
    <code>DECALN</code> (although DEC STD 070 mentions only
    top/bottom margins), and <code>DECSTR</code>.</li>

<li>corrected order of reset/move when setting
    <code>DECCOLM</code>, and make it more consistent by always
    resetting margins, rather than only when the mode is changed
    (report by James Holderness).</li>

<li>compile-in double-buffer support by default, changing the
    configure option to set the default resource value for
    <code>buffered</code> to true or false.</li>

<li>take in account the reverse-video state when computing the
    filler-color used when clearing the screen in double-buffering
    configuration.</li>

<li>correct logic for filtering scrollbar-updates when
    <code>buffered</code> resource is compiled-in but not enabled
    (report by Paul Lampert).</li>

<li>improve state saved/restored for cursor-save and SGR stack
    features.</li>

<li>improve description of 1006 and 1005 mouse modes, to avoid
    implying that they use character-parameters (report by Bryan
    Christ).</li>

<li>explain in <code>ctlseqs.ms</code> that some of the numeric
    keypad keys were xterm extensions rather than VT100/VT220
    terminal features (prompted by discussion with Thomas
    Wolff).</li>

<li>explain in <code>ctlseqs.ms</code> how the DEC windowing
    extension is supported by xterm.</li>

<li>add 28 rectangular editing to the primary response
    (suggested by Thomas Wolff).</li>

<li>fix a typo, improve wording in <code>ctlseqs.ms</code>
    (Thomas Wolff).</li>

<li>fix internal column-parameter when <code>SL</code> or
    <code>SR</code> is used with left/right margins (patch by
    Thomas Wolff).</li>

<li>fix off-by-one in VT52 graphics character mapping (patch by
    Thomas Wolff).</li>

<li>use <code>_X_UNUSED</code>, etc., when available as a
    fallback for <code>GCC_UNUSED</code>, etc., to reduce compiler
    warnings when building with <code><em>imake</em></code>.</li>

<li>update config.sub</li>

    Thornburg).</li>

<li>improve fixes for <code>DECCRA</code> handling of
    double-width characters (patch by Martin Hostettler).</li>

    by Martin Hostettler).</li>

<li>correct off-by-one in parameter limit-check for
    <code>DECCRA</code> (report by Martin Hostettler).</li>

<li>two fixes for the double-buffer configuration, prompted by
    MacPorts' switch to double-buffering (patch by Mike Thornburg,
    MacPorts #58313):

<ul>
        <li>ensure that the needSwap flag is set after drawing
        TrueType text</li>

<li>corrected the drawable-parameter used for the
        bar-cursor</li>
      </ul>
    </li>

<li>modify <code>ScrnRefresh</code> to ignore a case where the
    left/right halves of a double-width character have been set to
    different video attributes. The attribute to use is in the
    left-half (report/testcase by Thomas Wolff).</li>

    target lies off-screen (report/testcase by Thomas Wolff).</li>

<li>documentation errata (report by Thomas Wolff).</li>

<li>a check of <code>zIconBeep</code> resource was removed in
    double-buffer fix in <a href="#xterm_334">patch #334</a>. That
    is used to decide whether to handle struct-notify events. When
    xterm does handle the events, it may negotiate a new
    window-size with the window manager. In that case, the
    <code>limitResize</code> resource setting limited the new
    window-size to the screen-size. Amended that by eliminating the
    limit for this special case when double-buffer is configured,
    and restoring the check for <code>zIconBeep</code> when
    double-buffer is not configured (Debian #919475).</li>

<li>disallow recursion which could happen if a user configures
    the <code>answerbackString</code> resource with the
    <code>ENQ</code> code and experiments with that code when
    <code>SRM</code> is enabled (report by by Martin
    Hostettler).</li>

<li>add remaining credits in <code>COPYING</code> file.</li>

<li>modify <code>run-tic.sh</code> to check if it is using an
    older version of ncurses which does not support large terminal
    descriptions, and if so, remove a non-essential feature to keep
    within the 4096-byte legacy limit.</li>

    keepClipboard resource setting and corresponding menu
    entry.</li>

<li>fix an inconsistency between private mode 12 (the AT&amp;T
    610 cursor blink) and <code>DECSCUSR</code>: the former relied
    on having the <code>cursorBlink</code> resource set initially
    to enable the escape sequence, while the latter does not.</li>

<li>add private modes 13 and 14, as well as resource
    <code>cursorBlinkXOR</code> to allow better control over the
    cursor-blinking state (discussion with Bram Moolenaar).</li>

<li>modify the html and svg screen dumps to support direct

    as well as direct color.</li>

<li>improve options-parsing for query-status.pl script.</li>

<li>modify parsing of <code>SGR</code> direct-color control
    making <em>color space identitier</em> optional. The

    empty (default) field for the identifier.</li>

<li>add wide-attributes to <code>DECRQSS</code> reply for
    <code>SGR</code>.</li>

<li>add private mode 1046 to help with scripting

    #879936).</li>

<li>work around a special case of <em>Xft</em>'s mismanagement
    of its cached data by adding a check before the
    <code>-report-fonts</code> option to ensure that it does not
    use an <code>XftPattern</code> which may have been freed during
    a call to <code>XftFontOpenPattern</code>.</li>

<li>improve manual page description of <code>regex</code>
    option for <code>on<em>X</em>Clicks</code> resources (report by
    Lukas Mai).</li>

<li>improve legacy/NRC character set mapping (patch by Thomas
    Wolff), e.g.,

<ul>
        <li>enable alternate NRC set designators for French and
        French Canadian, &lsquo;9&rsquo; and &lsquo;f&rsquo;
        respectively, as documented in ctlseqs. (&lsquo;9&rsquo; is
        documented for VT510, &lsquo;f&rsquo; is a Kermit

<h1><a name="xterm_330" id="xterm_330">Patch #330 -
  2017/06/20</a></h1>

<ul>
    <li>updates for ReGIS (Ross Combs):

<ul>
        <li>remove redundant text command error check which broke
        <code>T(B)</code> and <code>T(E)</code>.</li>

<li>retain the loading alphabet number across multiple
        &ldquo;L&rdquo; commands.</li>

<li>add <code>S(T)</code> delay handler.</li>

<li>fix some color handling error messages.</li>

<li>add stubbed-out macrograph handling.</li>

<li>use <code>fragment_remaining()</code> and
        <code>fragment_consumed()</code> instead of manually
        checking position / length in various places.</li>

<li>rename some local variables in string / extent / option
        parsing</li>

<li>wrap some long lines.</li>

<li>move macrograph command handling out of the
        top-level.</li>
      </ul>
    </li>

<li>add a summary of the italic fonts loaded to
    <code>-report-fonts</code> option.</li>

<li>modify the font-lookup for italics to allow for
    &ldquo;<code>-i-</code>&rdquo; if no match is found with slant
    &ldquo;<code>-o-</code>&rdquo; (prompted by patch by Ben
    Wong).</li>

<li>change default values for <code>mkSamplePass</code> and
    <code>mkSampleSize</code> to reflect generally-improved locale
    support in various operating systems (FreeBSD #219800).</li>

<li>modify <code>wcwidth.c</code> to return -1 for non-Unicode
    values, and adjust a couple of blocks to better match
    assumptions about ambiguous-width characters in other
    implementations. Also modify <code>wcwidth.c</code> to support
    configurable soft-hyphen, so there is no drawback to using this
    version rather than a system <code>wcwidth</code>.</li>

<li>amend change made in <a href="#xterm_328">patch #328</a>
    for cursor-visibility to handle case where an application is
    updating the reverse-video state (FreeBSD #219800).</li>

<li>update tables of combining and ambiguous-width characters
    in wcwidth.c based on Unicode 10.0.0.</li>

<li>build-fix for <code>--enable-sixel-graphics</code> without
    <code>--enable-regis-graphics</code> (reports by Sven Joachim,
    FreeBSD #219945).</li>
  </ul>

<h1><a name="xterm_329" id="xterm_329">Patch #329 -
  2017/06/12</a></h1>

<ul>
    <li>add control sequences for reading the Sixel and ReGIS
    graphics sizes (suggested by Ben Wong).</li>

<li>add a workaround for <code>wcwidth</code> returning -1 for
    characters which should have been printable (FreeBSD
    #219800).</li>

<li>fix a bug in font initialization from <a href=
    "#xterm_328">patch #328</a> (FreeBSD #219800).</li>

<li>fix a special case in <code>HideCursor</code> which
    assigned a bold font to the slot used for normal font in
    changes for italics in <a href="#xterm_307">patch #307</a>
    (Debian #858304).</li>

<li>updates for ReGIS (Ross Combs):

<ul>
        <li>Strings specified with no command are used as
        "comments". Print these in the log when tracing.</li>

<li>Catch attempts to use "alternate display" mode (AKA
        "blink") from the GIGI, but do not implement it.</li>

<li>The <code>T(M)</code> command should only multiply the
        height by 10, not 20.</li>

<li>Make the <code>S(E)</code> command reset more state
        than just the screen contents.</li>

<li>Remove two rotation variables which were only being
        printed.</li>

<li>Numerous minor fixes and comment updates in the
        <code>R</code> command.</li>

<li>Unknown <code>R</code> command option names trigger an
        empty response.</li>

<li>Fix the output position after printing rotated text (it
        was missing the the sign before).</li>

<li>Fix the position change with pixelvectors and rotated
        text (the rotation transform was not being applied).</li>

<li>Update the <em>TODO</em> list and remove a verification
        <em>FIXME</em> (slanted text positioning is correct as
        is).</li>

<li>Emulate the approximately 1.4x enlargement for text
        which isn't rotated at right angles.</li>

<li>Only update the color planes specified in the plane
        mask (the <code>W</code> command's <code>F</code>
        option).</li>
      </ul>
    </li>

<li>fix a bug introduced by the changes to font information in
    <a href="#xterm_328">patch #328</a>. When processing the
    "checkfont" option of the <code>locale</code> resource, the
    program referred to the <em>request</em> data, to an array
    which was only allocated in the <em>new/result</em> widget
    (report by H Merijn Brand).</li>

<li>fix a missing assignment initialization to make the
    <code>utf8</code> resource control whether escape sequences to
    enable/disable UTF-8 mode are allowed.</li>
  </ul>

<h1><a name="xterm_328" id="xterm_328">Patch #328 -
  2017/06/01</a></h1>

<ul>
    <li>revise parser for <code>charClass</code> resource, making
    these improvements:

<ul>
        <li>accept octal and hexadecimal values</li>

<li>allow embedded whitespace</li>

<li>allow the class after colon to be optional, e.g., to
        clear class settings for a range of characters.</li>
      </ul>
    </li>

<li>add command-line option
    <code>-report-charclass</code>.</li>

<li>fix most lintian warnings about test-package</li>

<li>add <code>eraseSavedLines</code> resource.</li>

<li>document <code>DECSED&nbsp;3</code> in
    <code>ctlseqs.ms</code> (report by Ben Longmans).</li>

<li>improve integration between configure-events and updates
    for reported screensize, in particular when switching between
    vt100 and tek4014 modes.</li>

<li>modify selection-highlighting of reverse-video text to keep
    that distinct, e.g., by reversing the selection foreground and
    background colors as one would expect. This fixes a "useless"
    case in the description of
    <code>highlightColorMode</code>.</li>

<li>improve fix for Debian #759734, addressing a case where
    non-colored cursor would be invisible against reverse-video
    (see <a href="#xterm_311">patch #311</a>).</li>

<li>updates for ReGIS (Ross Combs):

<ul>
        <li>the "H" option of the "T" command should multiply by
        10, not 20.</li>

<li>display unknown glyphs as a solid block.</li>

<li>given a succession of text-direction options, use the
        last.</li>

<li>fix the direction of ReGIS slanted text so that
        negative values produce oblique output .</li>

<li>fix the ReGIS text direction option to only rotate
        characters when no following size option is used.</li>
      </ul>
    </li>

<li>update terminfo to better match corresponding entries in
    ncurses, e.g., <code>u8</code> pattern to match the VT220,
    VT420, etc., primary responses, as well as adding
    <code>smxx</code> and <code>rmxx</code>.</li>

<li>fixes from J&ouml;rg Sommer:

<ul>
        <li>corrected a trace-message regarding maximum
        graphics-size; it used the similar ReGIS maximum size which
        might not be configured.</li>

<li>in <code>do_select_regex</code>, clear selection if
        there is no match. If the regex does not match anything
        around the cursor, the selection returned must be empty,
        otherwise the whole line is treated as a match. This way
        the command defined by <code>exec-selectable</code> will
        not be executed if there is no match.</li>

<li>modify limit in <code>do_select_regex</code> to include
        the character at the cursor in the match, making it easier
        to type something and then hit the key to trigger
        <code>exec-selectable</code>.</li>

<li>If <code>exec-selectable</code> or
        <code>insert-selection</code> is triggered by a mouse
        button click, the position of the mouse pointer should be
        used. This makes it easier to address any position on the
        window and it makes it possible to use the mouse, e.g., for
        applications such as mutt where you cannot move the
        cursor.</li>
      </ul>
    </li>

<li>modify <code>DECRC</code> to save/restore xterm's
    last-column flag used to control wrapping behavior rather than
    manipulating <code>DECAWM</code> (report/analysis by Mattias
    Engdeg&aring;rd).</li>

<li>add configure option <code>--enable-terminfo-env</code> to
    use the value set by <code>--with-own-terminfo</code> for the
    <code>$TERMINFO</code> environment variable. That variable was
    set automatically for HPUX, but would be useful in other
    systems, e.g., for Solaris (request by Jeff Wieland).</li>

<li>fix a race condition when setting up a signal handler to
    timeout if opening <code>/dev/tty</code> hangs (patch by Tobias
    Stoeckmann).</li>

<li>review/cleanup resources which were not in the manual page
    (report by Maxwell Anselm):

<ul>
        <li>add manual page description as needed.</li>

<li>drop resource name for <code>menuBar</code>, as
        unnecessary.</li>

<li>modify fallback numeric value for
        <code>regisScreenSize</code> resource to match that for
        <code>maxGraphicSize</code>.</li>
      </ul>
    </li>

<li>updated configure macros <code>CF_ADD_CFLAGS</code>,
    <code>CF_CC_ENV_FLAGS</code>, <code>CF_GNU_SOURCE</code>,
    <code>CF_MATH_LIB</code>, and <code>CF_XOPEN_SOURCE</code> from
    other program-changes.</li>

<li>update config.guess, config.sub</li>

<li>change &ldquo;maximum screensize&rdquo; assumed by
    <code>resize</code> to 9999x9999, to accommodate people using
    the <em><code>Unreadable</code></em> font.</li>

<li>drop <code>Utility</code> from default value of
    <code>--with-desktop-category</code> (Debian #780176).</li>

<li>widen the configure script pattern used for finding related
    ".desktop" files, including &ldquo;Terminal&rdquo;</li>

<li>several minor improvements to font utility functions:

<ul>
        <li>provide for later modification to implement font-sets
        by parsing the font resources as comma-separated
        lists.</li>

<li>parse <code>-fn</code> and <code>-fa</code> similarly,
        using &ldquo;x:&rdquo; and &ldquo;xft:&rdquo; prefixes for
        font name/family strings to distinguish between XLFD and
        Xft font specifications.</li>

<li>use loops to iterate over font classes</li>

<li>use getters/setters for font data to allow for
        on-demand lookups.</li>

<li>make the debugging trace for missing glyph less verbose
        since that interferes with the <code>-report-fonts</code>
        option.</li>

<li>refactor <code>xtermLoadFont</code> to make it clearer
        how some fonts are derived from others, e.g., bold,
        wide.</li>

<li>make the triggering and suppressing of font-warnings
        more consistent by storing the last state in the
        widget.</li>

<li>reduce font-warnings by checking for repeated
        warnings.</li>
      </ul>
    </li>

<li>add <code>vttests/query-status.pl</code></li>

<li>add <code>vttests/closest-rgb</code></li>

<li>add special case for displaying soft-hyphen if it happens
    to fall at the right margin, and omitting similar case such as
    the BIDI markers, where a zero-width character is neither a
    control character nor a combining character (Debian
    #844325).</li>

<li>modify logic for <code>OSC&nbsp;52</code>, <em>manipulate
    selection data</em>, to update the selection-time to include
    the latest X events. This fixes some cases where the selection
    was invalid, e.g., after an event due to focus-follows-mouse
    (report/testcase by Stephane Chauveau).</li>

<li>revise macro <code>CastMallocN</code> as new macro
    <code>TextAlloc</code> to make explicit use of
    <code>sizeof(char)</code> (prompted by patch by Cade
    Foster).</li>

<li>add <em>&ldquo;Mouse Ops&rdquo;</em> menu entry and related
    resources to allow runtime disabling/enabling of the mouse
    protocol escape sequences (discussion with Bob Proulx).</li>

<li>improve discussion of mouse actions versus protocol in the
    manual (discussion with Bob Proulx).</li>

<li>improve discussion of environment variables in the manual,
    pointing out where some features (such as termcap and the
    System5 <code>COLUMNS</code> and <code>LINES</code> variables)
    are used rarely, mainly to support legacy applications.</li>

<li>add examples of <code>translations</code> resource for
    select/paste, and for font-size changes to the manual.</li>

<li>minor reordering of some entries in <code>ctlseqs.ms</code>
    for consistency (report by Arran Ubels).</li>

<li>add <code>-s</code> option to <code>256colors2.pl</code>
    and <code>88colors2.pl</code>, to demonstrate modifying the
    &ldquo;system&rdquo; colors 0&ndash;15.</li>

<li>omit <code>XFT_SPACING</code> property from call to <code>
      XftPatternBuild</code>, to work around a bug in
      <em>fontconfig</em> for handling Google Go fonts, whose names
      sort in an order not expected by <em>fontconfig</em>, causing
      the request for a monospaced font to return <em>italics</em>,
      e.g.,

<blockquote>
        <pre>
$ fc-match 'Go Mono:spacing=monospace'
Go-Mono-Italic.ttf: "Go Mono" "Italic"
(report by Giacomo Boffi on <a href=
"http://unix.stackexchange.com/questions/324941/xterm-displays-an-italic-face-instead-of-regular">Stackoverflow</a>).

<h1><a name="xterm_327" id="xterm_327">Patch #327 -

    when <code>allowC1Printable</code> is set (Debian
    #738794).</li>

<li>use consistent error-checking after <code>strtol</code>

        response a multiple of four characters.</li>

<li>modify <code>_ConvertSelectionHelper</code> to not stop

<li>add support for scaling and mirrored coordinate systems
        to the screen address command</li>

<li>sets a minimum ReGIS graphics size of 100x100 --
        smaller address ranges will be scaled up</li>

<li>reset the image if either the width or height is zero
        (which should happen together or not at all, but switching
        the logic gets rid of some parentheses)</li>

<li>adds support for alternate screen coordinates (just
        offsets, not inverted coordinates or scaling)</li>

<li>keeps the graphics state across ReGIS calls unless P1
        or P3 entry codes are used</li>

<li>changes loops to continue after parsing whitespace to
        allow trailing whitespace</li>

<li>fixes some incorrect character casts</li>

<li>improve use of const, e.g., for the <code>LineData</code>
    pointers (patch by Ross Combs).</li>

    screen (patch by Ross Combs).</li>

<li>amend change to focus-change events in <a href=
    "#xterm_287">patch #287</a> to limit it to suppressing the

<li>minor fix to <code>vttests/resize.pl</code> to avoid
    undefined variable when receiving broken/missing response,
    e.g., from mrxvt.</li>

<li>change the way that ReGIS graphics are refreshed (patch by
    Ross Combs):

<ul>
        <li>it pre-composes any overlapping graphics to avoid
        unnecessary and flickering draws</li>

<li>it adds a three-dimensional lookup table for RGB -&gt;
        pixel values and uses this across all graphics</li>

<li>it draws in line segments when there is a run of the
        same color</li>

<li>in cases where there are no transparent parts, it uses
        an XImage to draw</li>

<li>it hooks into the double-buffering support if it is
        enabled (though this doesn't seem to get rid of all
        flicker).</li>
      </ul>
      This has the effect of reducing flicker and speeding up

    incomplete (report by Jim Reisert).</li>

<li>fix typo in manpage (report by Vincent Lefevre).</li>
  </ul>

<h1><a name="xterm_289" id="xterm_289">Patch #289 -
  2013/02/08</a></h1>

<ul>
    <li>revert the <a href="#xterm_282">patch #282</a> change which
    restored "lost" text after shrinking/growing the screen size.
    If the screen was updated between the two resizing operations,
    unexpected text might be shown at the end (report/testcase by
    Joe Peterson).</li>

<li>reverse the arrow-keys sent for
    <code>alternateScroll</code> to match the usage in browsers
    (suggested by Dieter Roelants).</li>

<li>modify mouse reports to consistently indicate motion events
    whether or not a button is pressed. Old behavior (since
    <a href="#xterm_127">patch #127</a> modified encoding for wheel
    mouse) showed only that the button was released if no button
    had been pressed (report by Andy Koppe).</li>

<li>correct and improve behavior for SGR 1006 mouse protocol on
    button release in any-event mode. Initial implementation in
    <a href="#xterm_277">patch #277</a> left internal state showing
    the last button pressed when reporting motion events. It now
    keeps track of all buttons which have been pressed and
    released, showing the lowest remaining button by number in the
    response (reports by Hayaki Saito, Andy Koppe).</li>

<li>fix inconsistency between <code>TermColors</code> and
    <code>OscTextColors</code> enums which interchanged values for
    tektronix cursor color and highlight foreground in control
    sequences in <a href="#xterm_225">patch #225</a> (report/patch
    by Peder Stray).</li>

<li>fix inconsistent use of noreturn-attribute in
    <code>Exit</code> function which interfered with clang
    --analyze.</li>

<li>remove incorrect <code>free</code> used in computation of
    <code>XTERM_SHELL</code> variable, from Coverity fixes in
    <a href="#xterm_288">patch #288</a> (FreeBSD #175782).</li>

<li>add <code>--with-valgrind</code> option to configure script
    for consistency with my other programs.</li>

<li>update table of ambiguous width characters in wcwidth.c
    based on Unicode 6.2.0</li>

<li>update table of combining characters in wcwidth.c based on
    Unicode 6.2.0</li>

<li>update precompose.c based on Unicode 6.2.0</li>
  </ul>

<h1><a name="xterm_288" id="xterm_288">Patch #288 -
  2013/01/09</a></h1>

<ul>
    <li>fix a special case in <code>ShowCursor</code> where the
    foreground and background colors of the current position are
    the same. In that case, choose the further of the window's
    foreground and background colors for the cursor color.</li>

<li>modify <code>alternateScroll</code> feature added in
    <a href="#xterm_282">patch #282</a> to use either
    <code>CSI</code> or <code>SS3</code> according to the cursor
    keys application mode setting, to simplify using it in vi, etc.
    (suggested by Dietar Roelants).</li>

<li>revise manpage for <code>resize</code> to clarify the
    changes which <code>resize</code> may make to the terminal
    settings as well as to the terminal itself.</li>

<li>remove code such as <code>struct ttysize</code>, used for
    SunOS 3 and 4.</li>

<li>modify configure script and makefile to check for
    <code>groff</code> and suppress groff-specific rules if groff
    is not found.</li>

<li>modify ctlseqs.ms and makefile to work around bugs in
    <code>grohtml</code> which cause ".png" files to be truncated
    when producing html documentation.</li>

<li>modify suffix rules for "make docs" to make the names of
    the generated ".png" files predictable, helping to work around
    longstanding problems with this feature of groff&mdash;none of
    its releases work for <em>all</em> of xterm's tables..</li>

<li>correct typo in ctlseqs.ms for DECIC and DECDC; the
    character preceding the final "<code>~</code>" is an ASCII
    single-quote "<code>'</code>" rather than a space (report by
    Paul LeoNerd Evans).</li>

<li>update CF_GCC_VERSION macro, handling both Debian and
    Darwin.</li>

<li>improve configure script checks for the
    <code>--with-desktop-category</code> option. After <a href=
    "#xterm_280">patch #280</a> changes, if no value was given for
    this option, and no existing desktop files found for
    comparison, the incorrect "auto" value was passed into the
    generated desktop file (report by Julien Cristau).</li>

<li>modify sample build-scripts to disable check for
    <code>imake</code> due to code-rot in Xorg.</li>

<li>add <code>-v</code> command-line option to
    <code>resize</code>, reporting the same version string as
    <code>xterm</code> and the two shell-wrappers.</li>

<li>make name-transformation apply to other occurrences of
    <code>resize</code>, other manpages.</li>

<li>special-case the name-transformation in xterm's manpage in
    the NAME section so that the result works with
    <code>makewhatis</code> (report by Julien Cristau).</li>

<li>modify install-rules for manpages to put each program's
    respective transformed name into the header rather than
    xterm's.</li>

<li>remove deprecated files: proto.h, os2main.c</li>

<li>minor fixes based on Coverity scan, including:

<ul>
        <li>correct caching of Atom value for the font menu's
        "Selection" entry.</li>

<li>ensure that utmp/utmpx calls do not depend upon
        trailing nulls in the <code>ut_id</code> and
        <code>ut_line</code> values.</li>
      </ul>
    </li>
  </ul>

<h1><a name="xterm_287" id="xterm_287">Patch #287 -
  2012/11/25</a></h1>

<ul>
    <li>fix a case where in_put() loop could continue when it has
    found an X event rather than the pty, causing the pty-read to
    be delayed (patch by Balazs Kezes).</li>

<li>add option to <code>pointerMode</code> resource and
    corresponding control sequences to allow text-cursor to remain
    hidden if the pointer leaves/enters the window via accelerator
    keys. Ordinary motion within the window restores the pointer
    (prompted by patch by Balazs Kezes).</li>

<li>remove special case of modifiers for the
    <code>Mode_switch</code> and <code>XK_ISO_Level3_Shift</code>
    from <a href="#xterm_223">patch #223</a>. Verified that the
    conflict which this was intended to resolve does not happen for
    normal compose- or modeswitch-handling (prompted by patch by
    Balazs Kezes, Debian #638694).</li>

<li>modify the handling of focus-change events to ignore those
    whose detail is <code>NotifyPointer</code>, since those are
    sent in addition to focus-change events directed to the old/new
    windows having focus. In particular, this prevents the
    urgency-hint from being reset inadvertently (prompted by patch
    by Balazs Kezes).</li>

<li>modify description of <code>iconName</code> in manpage to
    make it clearer that this resource does not specify the
    filename of an icon (discussion with Ian Collier).</li>

<li>modify <code>iconHint</code> resource to allow suppressing
    the built-in icon by setting this to "none" (discussion with
    Ian Collier).</li>

<li>make <code>-iconic</code> option work with the toolbar
    configuration.</li>

<li>correct initialization of window manager hints used to set
    the icon-pixmap. That detail from <a href="#xterm_282">patch
    #282</a> overwrote state used to control the
    <code>-iconic</code> command-line option (report by Ian
    Collier).</li>

<li>fix paste64 feature for the case where the selection comes
    from the current terminal. The selection callback can happen
    after the reply is partly built, making it necessary to flush
    the reply-buffer to keep things in the proper order (report by
    Ailin Nemui).</li>

<li>reject command-line options which are longer than the
    options in xterm's table, to avoid mismatches (Redhat
    #875305).</li>

<li>correct attribution for <a href="#xterm_282">patch #282</a>
    changes.</li>
  </ul>

<h1><a name="xterm_286" id="xterm_286">Patch #286 -
  2012/10/29</a></h1>

<ul>
    <li>fix <code>minstall.in</code> to work with "make docs" rule,
    so that patch number appears in the corresponding generated
    documentation.</li>

<li>modify <code>minstall.in</code> to keep the name shown in
    the heading consistent with any renaming, e.g., for
    test-builds.</li>

<li>check for misconfigured <code>printerCommand</code>
    resource on the first use, warn and disable it if it does not
    specify an executable command (Debian #691642).</li>

<li>improve check for window-manager name needed to establish
    usable default for activeIcon resource. This works around a
    scenario where <code>gdm</code> does incomplete cleanup,
    leaving window properties that refer to windows which no longer
    exist (Redhat #869959).</li>
  </ul>

<h1><a name="xterm_285" id="xterm_285">Patch #285 -
  2012/10/23</a></h1>

<ul>
    <li>add/adapt FreeBSD ports files for test-building.</li>

<li>modify <code>minstall.sh</code> to use the patch-number and
    date in the manpage footer.</li>

<li>add check for failure to allocate the fg/bg colors at
    startup, e.g., misconfiguration. Work around by setting both to
    the default colors (suggested by Scott Bertilson).</li>

<li>amend change for <a href="#xterm_280">patch #280</a> which
    added <code>modifyKeyboard</code>, to make
    <code>modifyOtherKeys</code> work (report by Ailin Nemui).</li>

<li>add <code>query-colors.pl</code> example for
    OSC&nbsp;4.</li>

<li>correct mis-applied fix for minstall.sh (report by Miroslav
    Lichvar).</li>
  </ul>

<h1><a name="xterm_284" id="xterm_284">Patch #284 -
  2012/10/14</a></h1>

<ul>
    <li>amend configurability changes for icons from <a href=
    "#xterm_283">patch #283</a>, moving the new functionality to
    the <code>iconHint</code> resource to avoid conflict with
    existing uses of the <code>iconName</code> resource in the
    <code>Shell</code> widget (report by Emanuel Haupt).</li>

<li>fix documentation errata reported by Miroslav Lichvar:

<ul>
        <li>correct manpage default for <code>allowTcapOps</code>
        (see <a href="#xterm_243">patch #243</a></li>

<li>modify documentation for configure
        <code>--enable-backarrow-key</code> to match the script
        (see <a href="#xterm_280">patch #280</a>).</li>

<li>fix typo in <code>minstall.sh</code> in <a href=
        "#xterm_283">patch #283</a>, which made the leading-cap
        "Xterm" become "xterm" (patch by Miroslav).</li>
      </ul>
    </li>

<li>fix two typos in configure.in from <a href=
    "#xterm_283">patch #283</a> changes; one broke the
    <code>--regex</code> configure option (report by H Merijn
    Brand).</li>
  </ul>

<h1><a name="xterm_283" id="xterm_283">Patch #283 -
  2012/10/09</a></h1>

<ul>
    <li>modify makefile and script to generate appropriate renaming
    s/xterm/xterm-dev/ for test-package's manpage.</li>

<li>improve makefile rules for installing/uninstalling pixmap
    files, to include the newer mini- and filled- variants.</li>

<li>clarify change in manpage regarding <a href=
    "#xterm_282">patch #282</a> change to always set a
    window-decoration icon, even if <code>iconName</code> is not
    set.</li>

<li>add a fourth flavor of window-decoration icons,
    "filled-xterm" for a monochrome xterm with filled
    interior.</li>

<li>use shape-mask to improve contrast of the window-decoration
    icons.</li>

<li>minor changes to icon colors to improve contrast on
    bright-mud backgrounds.</li>

<li>drop configure checks for memmove versus bcopy, and
    strerror function; all currently tested platforms support
    these.</li>

<li>cleanup configure macros, as done in byacc 20121003.</li>

<li>improve configurability of the built-in icon selectable via
    the <code>iconName</code> resource.</li>

<li>update config.guess, config.sub</li>
  </ul>

<h1><a name="xterm_282" id="xterm_282">Patch #282 -
  2012/09/28</a></h1>

<ul>
    <li>improve configure check for
    <code>XkbKeycodeToKeysym</code>, fixing a regression on some
    older systems in the <a href="#xterm_280">patch #280</a>
    changes.</li>

<li>add clarification in manpage for
    <code>alwaysBoldMode</code> and <code>veryBoldColors</code>
    resources (prompted by Derek Martin question about using the
    former with TrueType fonts).</li>

<li>add <code>alternateScroll</code> resource and corresponding
    control sequences which modify the <code>scroll-forw</code> and
    <code>scroll-back</code> actions: when the alternate screen is
    displayed, wheel mouse up/down will send cursor keys (Debian
    #683942).</li>

<li>improve rendering for the case when a Unicode character is
    absent in the bold font but present in the normal font by
    temporarily falling back to the normal font (Debian #359006,
    Debian #408666).</li>

<li>provide configure option
    <code>--enable-double-buffer</code> and ifdef's to allow
    comparisons with/without double-buffering. The default uses
    normal buffering.</li>

<li>add feature to optionally scroll current page before
    clearing, controlled by resource setting
    <code>cdXtraScroll</code> (prompted by patch by Balazs
    Kezes):</li>

<li>integrated patches from Arch Linux forum posting (patches
    by Balazs Kezes):

<ul>
        <li>modify reallocation limit of line-data when resizing
        screen so that "lost" text will be restored if the screen
        is first shrunk and then grown.</li>

<li>modify output to use double-buffering to reduce
        flicker.</li>
      </ul>
    </li>

<li>modify <code>scroll-lock</code> action to handle
    on/off/toggle keywords like other actions. Previously the
    optional parameter was interpreted as an integer.</li>

<li>extend <code>DECSCUSR</code> to provide a way to set the
    cursor to a vertical bar (patch by Paul Bolle).</li>

<li>add <code>-8</code>, <code>-c</code>, <code>-d</code> and
    <code>-u</code> options to <code>88colors2.pl</code> and
    <code>256colors2.pl</code> scripts. No current terminal
    emulator recognizes C1 controls while handling UTF-8
    encoding&mdash;see notes in <a href="#xterm_119">patch #119</a>
    and <a href="#xterm_109">patch #109</a> regarding
    <code>utf8controls</code>&mdash;but the <code>-u</code> and
    <code>-8</code> options are useful for demonstrating this
    point.</li>

<li>improve speed when changing color palettes using OSC
    controls by deferring repaint while followup controls might be
    additional color palette changes.</li>

<li>modify <code>SGR&nbsp;38</code> and
    <code>SGR&nbsp;48</code> to accept RGB index, matching the
    closest entry in xterm's palette.</li>

<li>extend <code>SGR&nbsp;38</code> and
    <code>SGR&nbsp;48</code> to accept colon as parameter separator
    (request by Paul LeoNerd Evans).</li>

<li>modify <code>fullscreen</code> action to allow it to toggle
    the full-screen mode rather than only set or unset it (prompted
    by Eeri Kask's suggestion to support
    <code>_NET_WM_TOGGLE</code>). This implementation does not yet
    use <code>_NET_WM_TOGGLE</code>.</li>

<li>add support for <code>_NET_WM_STATE_MAXIMIZED_VERT</code>
    and <code>_NET_WM_STATE_MAXIMIZED_HORZ</code> EWMH properties
    (suggested by Eeri Kask).</li>

<li>make fullscreen mode work with the tek4014 window. This
    change makes only the currently active window to be changed to
    fullscreen rather than changing both windows.</li>

<li>modify <code>TekClear</code> function to discard pending
    output before clearing the tek4014 display (patch by Kevin
    Ryde).</li>

<li>fix <code>deleteIsDEL</code> feature, broken in <a href=
    "#xterm_280">patch #280</a> changes (report by Mike Thornburg,
    forwarded by Jeremy Huddleston).</li>

<li>fix a special case of wrapping double-width characters
    (report/test-case by Ken Winstein).</li>

<li>add <code>E3</code> extended capability to
    <code>xterm-basic</code> to match ncurses <a href=
    "https://invisible-island.net/ncurses/NEWS.html#t20120728">20120728</a>
    patch.</li>

<li>fix incorrect transformation of row-parameter for
    <code>ClearCurBackground</code> in <a href="#xterm_279">patch
    #279</a> which caused incorrect painting in some scrolling
    scenarios (report by Chuck Silvers).</li>

<li>fix typo in manpage description of <code>+maximized</code>
    option (Paul Maier).</li>

<li>change default for configure option
    <code>--with-xpm</code>, turning it on unless requested
    otherwise.</li>

<li>add configure option <code>--with-icon-name</code> which
    can be used to override the default icon used in
    icon-themes.</li>

<li>extend <code>activeIcon</code> resource to provide
    <code>default</code> value which tells xterm to determine the
    window manager's name and automatically enable the feature for
    fvwm and window maker. The explicit true/false values can be
    used to override this behavior.</li>

<li>add "mini" xterm icon, which scales better than the
    standard xterm icon, e.g., for the gnome/kde "panel"
    feature.</li>

<li>extend <code>iconName</code> resource to search for icon
    named according to resource value and use that if found. If not
    found, use compiled-in pixmap. Both set the WM_ICON_NAME
    property which is used by various window managers, usually for
    window decoration.</li>

<li>updated autoconf patch, adding support for --datarootdir,
    which changes the default location of manpages.</li>

<li>further improved autoconf macros for configuring icons,
    from vile 9.8h</li>
  </ul>

<h1><a name="xterm_281" id="xterm_281">Patch #281 -

<li>fix for configure script's search for icon file when it is
    not found in the current directory, e.g., when building out of
    tree (patch by Thierry Reding).</li>

<li>undo the XK_Home / XK_End change from <a href=

<h1><a name="xterm_280" id="xterm_280">Patch #280 -
  2012/06/24</a></h1>

<ul>
    <li>add configure check to work around warning from
    desktop-file-install for "Encoding", noting that it emits
    deprecation warnings without providing its version
    information.</li>

<li>add configure option <code>--with-icon-theme</code> to tell
    xterm whether to install into an icon theme, defaulting to
    "hicolor" (Redhat #755206, Redhat #799614 and Redhat
    #804279).</li>

<li>change <code>--with-icondir</code> to look for "icons"
    directory rather than "pixmaps" by default. Add new option
    <code>--with-pixmapdir</code> to allow these two uses to be
    installed concurrently.</li>

<li>modify configure options <code>--with-app-defaults</code>
    and <code>--with-icondir</code> to accept "auto" as value to
    look for existing directory from well-known locations.</li>

<li>add missing codes for secondary DA response which tell the
    type of terminal as in the primary DA response.</li>

<li>update primary DA response for VT420 to include user
    windows and horizontal scrolling.</li>

<li>add <code>modifyKeyboard</code> resource to support
    keypad-modifier changes per request by Thomas Wolff.</li>

<li>add XK_Home / XK_End to editing-keypad checks</li>

<li>add back-tab key <code>kB</code> to termcap entries to
    match the terminfo.</li>

<li>update terminfo to match corresponding entries in ncurses,
    e.g., add <code>XT</code> and adjust <code>sgr</code> string
    for xterm-bold entry.</li>

<li>add configure options to predefine the most commonly
    customized resources for terminal-settings, use those to
    substitute into the manpage the corresponding compiled-in
    values: <code>altSendsEscape</code>, <code>backarrowKey</code>,
    <code>backarrowKeyIsErase</code>, <code>deleteIsDEL</code>,
    <code>metaSendsEscape</code> (Redhat #819588).</li>

<li>change default emulation level to VT420 (discussion with
    Ailin Nemui).</li>

<li>improve logic for DECSCL; <a href="#xterm_279">patch
    279</a> partly enforced limitation of this to higher-level
    emulations. This patch finishes that change.</li>

<li>improve check for base of combining characters, preventing
    combination when cursor movement has intervened. Mosh's webpage
    gives two different examples of this, with other causes
    ascribed to the behavior.</li>

<li>modify IL/DL to set cursor to first column on row for
    better VT102/VT220 compatibility (prompted by code review of
    mosh).</li>

<li>separate state-table entries for DECSC/DECRC from the
    ANSI.SYS save/restore cursor, since the latter conflicts with
    DECSLRM when DECLRMM is enabled since <a href=

    exposure code, when deselecting a window (report by Kriston
    Rehberg).</li>

    modifies several controls to obey top/bottom and left/right
    margins.</li>

<li>correct macro definition used for testing modes used in
    ANSI/DEC request-mode controls introduced in <a href=
    "#xterm_262">patch #262</a>.</li>

<li>modify <code>x_getlogin</code> to check $LOGNAME and $USER
    before fallback to <code>getlogin</code>, so that user's choice
    for these variables can be carried forward to the xterm process
    (Debian #611487).</li>

<li>document DECSCUSR response for DECRQSS in ctlseqs.ms</li>

<li>add <code>zIconTitleFormat</code> resource to allow
    customizing the "***&nbsp;" prefixed to the icon title when the

    Adam).</li>

<li>modify DECSCUSR to update the same internal variable as
    RM/SM 12, and document in manpage the two variables used for
    controlling blinking cursor (report by Paul LeoNerd
    Evans).</li>

<li>correct response data for DECSCUSR in reply for DECRQSS
    response, which had inverted the blink-value (reports by Ailin
    Nemui, Paul LeoNerd Evans).</li>

<li>add a null-pointer check in <code>OkPasswd</code> macro to
    fix a problem in <code>resize</code> with Fedora 17 and a
    serial console (report/patch by Daniel Drake).</li>

<li>add workaround for Mac OS X, which loses the window size of
    a pseudo-terminal when the tty device is opened
    (report/analysis by Egmont Koblinger).</li>

<li>updated configure check for workable
    <code>posix_openpt</code> versus <code>grantpt</code>, from
    <code>luit</code> fixes.</li>

<li>modify DECIC/DECDC/DECBI/DECFI implemented in <a href=

<ul>
    <li>correct initialization for <code>eightBitMeta</code>
    resource (FreeBSD #164101).</li>

<li>make special check for Darwin 9 (and lower) to <em>not</em>
    use <code>posix_openpt</code> (report by Christian Ebert).</li>

<li>minor fixes (adding ".ne" directives) to reduce the cases
    where groff's utility for generating images for tables dumps
    core. Most versions of groff (I've found 1.19.2 to be the most
    stable) dump core when attempting to report that there are too
    few lines on a page for a table to be shown.</li>
  </ul>

<h1><a name="xterm_277" id="xterm_277">Patch #277 -
  2012/01/07</a></h1>

<ul>
    <li>remove special case for ISC pseudo-terminals which attempts
    to open the pty in two different ways.</li>

<li>move call to <code>grantpt</code> before asking utempter to
    add a record, to work with kFreeBSD which does not update the
    terminal's ownership until this point (Debian #652907).</li>

<li>document limitation of XIM interface in manpage (Debian
    #230787).</li>

<li>cleanup error reporting with new xtermWarning
    function.</li>

<li>add configure option <code>--disable-selection-ops</code>
    to make the new actions optional.</li>

<li>add four new actions for making the selection or data
    directly copied from the screen (prompted by discussion in
    Debian #637001, as well as report by Arjen van Tol):

<ul>
        <li>exec-formatted</li>

<li>exec-selectable</li>

<li>insert-formatted</li>

<li>insert-selectable</li>
      </ul>
    </li>

<li>add <code>visualBellLine</code> resource to allow
    <code>visualBell</code> to flash only the current line
    (prompted by patch by Gertjan Halkes).</li>

<li>add <code>eightBitMeta</code> resource to control the
    features which modify or interpret the eighth bit of a key when
    the meta modifier key is pressed (prompted by Debian
    #326200).</li>

<li>improve discussion of <code>eightBitInput</code> in the
    manpage (prompted by Debian #326200).</li>

<li>correct logic for <code>alt-sends-escape</code> action,
    overlooked when implementing <code>altSendsEscape</code>
    resource, which still used <code>eightBitInput</code> resource
    value.</li>

<li>add a workaround for <code>XAllocColor()</code>, which does
    not actually allocate "a read-only colormap entry corresponding
    to the closest RGB value supported by the hardware", but rather
    a rough approximation (Debian #650291).</li>

<li>undo parameter checks for <code>RequestResize()</code>
    added in <a href="#xterm_251">patch #251</a> and amended in
    <a href="#xterm_270">patch #270</a>, because zeros also are
    special cases (report by John S Urban).</li>

<li>modify some test-scripts to use <code>/bin/echo</code>
    rather than the shell's possibly-builtin <code>echo</code>, to
    work around broken configuration on Mac OS X, i.e., neither
    honoring the option nor flagging an error.</li>

<li>add SGR 1006, as a better technical solution than SGR 1015:

<ul>
        <li>the responses will not be confused with line-deletion
        and scrolling controls.</li>

<li>the button encoding is a little simpler, since it does
        not add an unnecessary 32 because the integer parameter
        does not have to be represented as a printable
        character.</li>

<li>the control responses for pressing and releasing a
        mouse button differ, allowing an application to tell which
        button was released.</li>
      </ul>

<p>Besides these improvements, in discussion, it was noted
      that urxvt's implementation of 1005 is incorrect, relying
      upon a locale that provides UTF-8 encoding. In contrast,
      vttest demonstrates a correct decoding, independent of
      locale.</p>
    </li>

<li>add support for urxvt SGR 1015 to address shortcoming of
    SGR 1005 with luit (patch by Egmont Koblinger).</li>

<li>add ISO and DEC controls useful for left/right
    scrolling.</li>

<li>add some changes for OpenBSD and MirBSD (adapted from patch
    by Thorsten Glaser):

<ul>
        <li>disable search for non-Unix96 ptys.</li>

<li>fix a gcc warning in
        <code>timestamp_filename</code></li>

<li>modify <code>Imakefile</code> to install xterm setgid

    pseudo-terminal.</li>

<li>modify special errno handling case in ptydata.c from
    <a href="#xterm_158">patch #158</a> to allow for the
    possibility that any platform may have special cases where
    "/dev/tty" is absent. For example, this can happen in a FreeBSD
    jail (patch by David Wolfskill).</li>

<li>add keyboard logic to map shift-tab into XK_ISO_Left_Tab,
    which is usually, not always, done by the X keyboard
    configuration.</li>

<li>portability fixes for some configure macros:
    <code>CF_XOPEN_SOURCE</code></li>

    <li>modify clipping limits for TrueType fonts to account for
    the <code>scaleHeight</code> resource setting, to work around
    another problem due to recent FreeType changes. In this case,
    the <code>DejaVu Sans Mono</code> set to pixelsize=13.5 is
    truncated because the font descent is reduced by FreeType to
    match an incorrect height metric (report by Adam Lee).</li>

<li>improve recovery when bitmap fonts are not installed, e.g.,
    so that switching font-sizes works for TrueType fonts.</li>

<li>modify lookup for <code>XTERM_SHELL</code> feature to allow

    <li>corrected initialization of "misc" resource values, to
    ensure that xterm has allocated a copy of strings which may not
    have been malloc'd by the X library (Debian #600129).</li>

<li>modify handling of any-event/any-button mouse protocol; it
    now is active with any combination of key-modifiers.</li>

    double-click will select past the end of a line.</li>

<li>build-fix to address change in include-guards for
    <code>Xlib.h</code> in ongoing Xorg edits (patch by Jeremy
    Huddleston).</li>

<li>improve <code>pointerMode</code> by continuing to watch for
    motion events after mouse tracking is disabled if the pointer
    is hidden (Debian #594856).</li>

<li>further extend initialization for active-icon font to check
    if the font was not loaded successfully, to retry with
    <code>font1</code>, or as even (if TrueType fonts are used) to
    use a TrueType font. The retries are to help with cases as in

<li>implement ANSI and DEC request-mode control sequences. The
    latter includes the xterm-specific private modes such as the
    mouse mode. The feature is ifdef'd with the rectangle
    operations since its decoding overlaps that feature.</li>

<li>when TrueType font is selected, querying returns the
        name of the TrueType font.</li>

<li>fix an (old) bug which did not restart the timer for
    blinking text if the only blinking text was temporarily
    scrolled out of view, e.g., using the scrollbar.</li>

<li>fix an (old) flaw in the delete-line operation where the
    text which is scrolled into view while the display is scrolled
    up was not repainted.</li>

<li>improve delete-line and insert-line operations, retaining
    selection when the selection does not intersect the
    deleted/inserted lines.</li>

<li>fix an (old) off-by-one error when an application cleared
    above the cursor position while the display was scrolled up,
    that would leave an extra line of text uncleared.</li>

<li>fix a similar problem where the double-size attribute would
    not be reset when clearing the screen while the display was
    scrolled up.</li>

<li>fix an indexing error which would occur if an application
    cleared a line while the display was scrolled up and was also
    in UTF-8 mode (Redhat #524503). The error was from <a href=

    gcc-specific bitfields (Debian #541236).</li>

<li>modify initialization of screen buffers to ensure that

    introduced in <a href="#xterm_244">patch #244</a> where the
    color- and character-arrays (stored after the video-attributes

<ul>
    <li>correct a special case in saving FIFO-lines from <a href=
    "#xterm_244">patch #244</a>. If the screen was shrunk, xterm
    used the wrong amount for copying to FIFO-lines, and then used
    this amount to adjust the current row on the screen. That was
    both a visible defect (Debian #541109) as well as a potential
    addressing error (Debian #541132, Debian #541160, and Debian
    #541236).</li>

<li>add clarification in xterm manual about the various

    improving performance. Added configure option
    <code>--enable-fifo-lines</code> to enable/disable the new
    feature (it is enabled by default).</li>

<li>added <code>fastScroll</code> resource, to amuse people who
    measure terminal emulator performance by <code>cat</code>'ing
    large files to the screen.</li>

<li>modify check in <code>readPtyData</code> from return values
    to provide exit on zero-bytes read from pty for FreeBSD, or
    eliminate high-CPU in "xterm-hold" processing (discussion with
    Ulrich Spoerlein, FreeBSD ports/136686). The check was
    originally modified to combine negative/zero values in
    XFree86-3.1.2E, 1996/05/06.</li>

<li>add configure option <code>--enable-16bit-chars</code> to
    provide wide-characters with 16-bits (rather than the default
    32-bits).</li>

<li>add <code>retryInputMethod</code> resource to allow
    configuring out the retries xterm uses to connect to
    non-responsive XIM server, to work around defective X
    configurations as noted in <a href=
    "http://mail-index.netbsd.org/tech-x11/2009/06/07/msg000511.html">
    NetBSD mailing list</a>.</li>

<li>make regular-expression selection work for VT100
    double-sized characters.</li>

<li>improve layout when drawing missing characters in a
    proportional font, e.g., as boxes, to take into account whether
    they are double-width (report by Guilbert Stabilo on
    comp.unix.shell).</li>

<li>add capability for keypad-center (kb2/KA2) to termcap entry
    for xterm-new, as well as xterm-8bit, xterm-sun and xterm-vt220
    (FreeBSD conf/136336).</li>

<li>change default for <code>keepSelection</code> resource to
    true (prompted by discussion with David Muir Sharnoff).</li>

<li>remove a limit-check in ptydata.c, allowing Unicode values
    past 64k to be displayed using TrueType fonts (Debian
    #458432).</li>

<li>remove a vt52-specific ifdef to allow mapping F1-F4 to
    PF1-PF4 when vt52 support is not compiled (report by Olaf
    'Rhialto' Seibert).</li>

<li>save/restore line-wrapping flags when converting from
    ISO-8859-1 encoding to UTF-8 encoding, as well as when resizing
    screen.</li>

<li>remove extra adjustment of position in fix for Debian
    #418324.</li>

<li>modify default check for <code>mkWidth</code> resource to
    check for line-drawing characters, which are categorized as
    double-width in Solaris 10 (report by Sebastian Kayser).</li>

    <code>menuLocale</code> resource.</li>

<li>fix an old (X11R5) bug in tek4014 for switching
    fontsizes.</li>

<li>add resource <code>defaultString</code> to make
    configurable the use of "#" when pastes of UTF-8 text fail due
    to limitations in the current locale settings.</li>

<li>make the set of selection target Atom's configurable by two
    new resources <code>eightBitSelectTypes</code> and
    <code>utf8SelectTypes</code>, e.g., to use the
    <code>TEXT</code> Atom in preference to
    <code>UTF8_STRING</code> (discussion with Stanislav Sedov
    regarding koi8rxterm and the FreeBSD port).</li>

<li>modify handling of <code>TARGETS</code> Atom by making it
    return exactly the set of targets as those which xterm is
    currently providing.</li>

<li>set <code>MANPAGER</code> and <code>PAGER</code> explicitly

    &#1057;&#1077;&#1084;&#1105;&#1085;).</li>

<li>improve error-checking of tcap-query parser.</li>

<li>add check for keyboard <code>tcap</code>), which ensures
    that terminal descriptions containing the same string for
    shifted/unshifted keys will be seen by tcap-query as only the
    unshifted key. (This would only happen with an incorrect
    terminal description).</li>

<li>fix conversion for input event-state to modifier-parameter
    which made tcap-query feature not work with
    <code>tcapFunctionKeys</code> (keyboard type
    <code>tcap</code>).</li>

<li>add "DEF_ALLOW_<em>XXX</em>" definitions to main.h to allow
    overriding the default compiled-in values for

    or disabling the font, termcap (tcap-query), title and window
    operations.</li>

<li>add <code>fontWarnings</code> resource, to control whether
    to show warnings on failure to load a font.</li>

<li>improve warnings for unloadable fonts introduced in
    <a href="#xterm_240">patch #240</a> by limiting those to the
    cases where a font would be specified directly by a resource
    setting rather than a derived fontname.</li>

<li>further amend fix for Debian #252873 from <a href=
    "#xterm_197">patch #197</a> to treat a blank cell which does
    not have both foreground and background colored as a
    non-colored cell. This improves a special case where the cursor
    is on a blank cell which had foreground color scrolled in
    (report by Miroslav Lichvar).

<p>Also add the same logic when hiding cursor, so the outline
      matches the in-focus cursor.</p>
    </li>

<li>modify internals to reduce places PAIRED_CHARS() is used,
    making WriteText() and ScrnWriteText() accept IChar array, as
    well as providing a wrapper for drawXtermText().</li>

    both termios and legacy interfaces immediately after asking the
    system for the existing values since X11R6.1, rather than using
    them to provide inherited values. While the legacy interface
    has some constraints, e.g., on HPUX, the POSIX or termios
    interface should not. Your shell may reset these anyway

<h1><a name="xterm_216" id="xterm_216">Patch #216 - 2006/8/3</a></h1>

<ul>
    <li>improve handling of <code>ConfigureNotify</code> events by
    checking if there are further events in the queue which
    obsolete the current one (adapted from rxvt 2.7.5). Only the
    normal normal (non-toolbar) configuration is addressed in this
    patch.</li>

<li>several changes to terminfo:

<ul>
        <li>incorporate some minor changes from ncurses to help
        keep these synchronized:

<dd>modify sgr/sgr0 in xterm-new to improve tgetent's
            derived "me".</dd>

<dd>remove ncv flag from xterm-16color</dd>

<dd>improve xterm-256color by combining the 16-color
            setaf/setab strings with SGR 48, and cancelling the
            setf/setb strings.</dd>
          </dl>
        </li>

<li>use extended function-key definitions for xterm-sun,
        xterm-sco entries.</li>

<li>add terminfo building-blocks corresponding to the
        <code>modifyFunctionKeys</code> and
        <code>modifyCursorKeys</code> resources.</li>
      </ul>
    </li>

<li>ifdef'd Sun function-key feature to make it optional, like
    HP and SCO.</li>

<li>extend table for termcap-query feature through F63, and
    updated tcapquery.pl to match.</li>

<li>modify logic for function-key input processing to allow
    function key numbers which are constructed by control- and
    shift-modifiers to extend beyond X's hardcoded limit of
    35.</li>

<li>add control sequence to set or reset the
    <code>eightBitInput</code> resource.</li>

<li>change default resource <code>modifyFunctionKeys</code> to
    2 to avoid sending SS3 with parameters (report by Kalle Olavi
    Niemitalo).</li>

<li>add control sequences for setting and resetting the values
    of the <code>modifyCursorKeys</code>,
    <code>modifyFunctionKeys</code> and
    <code>modifyOtherKeys</code> resources.</li>

<li>add <code>modifyFunctionKeys</code> resource like
    <code>modifyCursorKeys</code>. Setting this to zero allows one
    to use the control- and shift-modifiers to construct function
    key strings, for terminals using many function keys, e.g., for
    <code>xterm-sun</code> or <code>xterm-sco</code>.</li>

<li>modify screen responses and function-key logic to reduce
    the number of writes made, to make it less likely that an
    application would read only part of a function-key in a read
    operation (suggested by John E Urbanczyk).</li>

<li>add <code>combiningChars</code> resource, which allows the
    user to specify the maximum number of combining characters that
    xterm will store for each cell in wide-character mode (prompted
    by request by Markus Kuhn to increase the limit from 2).</li>

<li>improve logic in <code>metaSendsEscape</code> in case the
    Alt- and Meta-keys are mapped to different modifiers. That
    allows one to use the Alt-key for shifting in the
    <code>eightBitInput</code> and use a Meta-key modifier to
    prefix the result with an <code>&lt;ESC&gt;</code>.</li>

<li>improve <code>modifyCursorKeys</code> logic to prevent it
    from modifying codes where <code>eightBitInput</code> or
    <code>metaSendsEscape</code> are set (request by Dan
    Nicolaescu).</li>

<li>improve <code>modifyCursorKeys</code> logic to prevent it
    from changing the user input when other modifiers such as AltGr
    are used (report by Thomas Wolff).</li>

<li>extend <code>modifyCursorKeys</code> to include the numeric
    keypad when in application mode.</li>

<li>improve <code>-reverse</code> (<code>-rv</code>) option
    (patch by Jason Vas Dias, Redhat #189161).</li>

<li>workaround for color resources on Fedora-5 which made the
    toolbar colors inconsistent.</li>

<li>corrected calls used for <code>--disable-setuid</code>
    option, add debugging traces to help diagnose this area.</li>

<li>modify configure script to ensure that
    <code>USE_UTMP_SETGID</code> is defined only if the check for
    POSIX saved-ids succeeds, or corresponds to one of the BSD
    systems known to have a workable <code>setegid</code>
    function.</li>

<li>extend configure check for POSIX saved-ids to include BSD
    systems</li>

<li>modify CF_SYSV configure macro to work with gcc on HPUX
    10.20, whose broken <code>&lt;term.h&gt;</code> relies on
    including <code>&lt;termios.h&gt;</code>.</li>

<li>change order of setuid/setgid ifdef checks in Imakefile to
    make it simpler to produce a setgid install, allowing the
    latter to override the former (prompted by an XFree86
    commit).</li>

<li>adapt a fix for setgid support from subsequent XFree86
    changes (patch by Emanuele Giaquinta).</li>

<li>further improve setgid support (patches by Emanuele
    Giaquinta).</li>

    source tarballs (requests by Bram Moolenaar, Emanuele
    Giaquinta).</li>

<li>add <code>modifyOtherKeys</code> resource, analogous to the
    <code>modifyCursorKeys</code> resource. This applies to keys
    that normally would transmit nothing when a given modifier is
    applied (request by Dan Nicolaescu).</li>

<li>add <code>default</code> to the acceptable values for the

    resource settings of <code>sunKeyboard</code>, etc.</li>

<li>correct ifdef's for <code>XkbBell()</code> which used the
    header file but not the corresponding function in <a href=

<li>fix Gentoo #90697 a different way, postponing the logic in
    <code>SetupToolbar</code> until the toolbar is actually needed,
    i.e., the <code>+tb</code> option is handled as expected.</li>

<li>revert fix made in <a href="#xterm_203">patch #203</a> for
    Gentoo #90697. That introduced a problem with the control mouse
    click-popups, while most of the performance problems can be
    resolved by restricting the menu fonts (report by Emanuele
    Giaquinta).</li>

<li>fix a file-descriptor leak when calling
    <code>openpty()</code> (OpenBSD system/4561).</li>

<li>make a special case of resizing work like vt100: a hard
    reset also resets the 132/80 mode. The code to support this was
    present since X11R5, but not used because the corresponding
    initial state of the <code>-132</code> option was not
    saved.</li>

<li>restore window manager hints after
    <code>XtMakeResizeRequest()</code> calls. One instance from
    <a href="#xterm_205">patch #205</a> resulted in the window
    manager displaying pixels rather than than characters after
    selecting a different font size (FreeBSD ports/87424).</li>

<li>remove special case for Darwin in CF_XOPEN_SOURCE (Emanuele

<li>amend adjustments for scrollbar layout from <a href=

    entering "sh -x uxterm". Also popup an xmessage to show the
    problem for users who run this via a GUI (Debian #318513).</li>

<li>improved some of the built-in line-drawing glyphs.</li>

<li>correct color of "box" character drawn for line-drawing
    glyph 1 (report by Nicolas George).</li>

<li>improve behavior when switching to UTF-8 mode after startup
    so xterm will check if the current fonts are already wide
    (ISO10646-1). If they are not, xterm will use the
    <code>utf8Fonts</code> subresource to load appropriate fonts

    contains no color resource definitions, e.g., after <a href=
    "#xterm_180">patch #180</a>.</li>

<li>add action <code>load-vt-fonts()</code> and configure
    option <code>--enable-load-vt-fonts</code> which allows users
    to define additional sets of VT-fonts which can be loaded at
    runtime.</li>

<li>add logic to wide-character support which attempts to load
    fonts specified by <code>utf8Fonts</code> subresources at
    startup. The subresources have the same names as the fonts
    which they replace, e.g., <code>font</code>,
    <code>font1</code>, etc., so that the ISO-10646-1 fonts can be
    specified in the <code>XTerm</code> app-defaults file (adapted
    from patch by Tomohiro Kubota).</li>

<li>improve Set Font escape string handling by making the
    relative settings apply to the size of the font, as in shift
    keypad plus/minus rather than the menu index.</li>

<li>simplify parameter passing for the <code>set-vt-font</code>
    action and related code.</li>

<li>cleanup some include-ordering, moving some recently-added
    hardcoded stuff into xterm.h where it will not interfere with
    the configure script.</li>

<li>modify <code>xtermAddInput()</code> (see note on
    augmentation in <a href="#xterm_158">patch #158</a>) to use the
    complete set of default keyboard translations so that one can
    use shifted pageup, wheel mouse, etc., while the mouse pointer
    is over the scrollbar. (Debian #178812).</li>

<li>make save/restore mode controls apply to show/blink cursor
    states.</li>

<li>add escape sequence to start/stop blinking cursor, which
    allows implementing <code>cvvis</code> terminfo capability
    (request by Nate Bargmann).</li>

<li>add <code>indp</code> and <code>rin</code> to terminfo
    entry.</li>

<li>fix an out-of-bounds array reference in ScrnRefresh() for

<ul>
        <li>translate Unicode values, i.e,. from UTF-8 output to
        xterm, for line-drawing to xterm's internal code, etc.,
        since TrueType fonts generally do not have either set of
        line-drawing glyphs. xterm can draw these directly (report
        by Abigail Brady).</li>

<li>pass 16-bit values rather than 8-bit values to
        xtermXftDrawString() to allow for wide-characters.</li>

<li>remove spurious check for <code>colorBDMode</code>
        resource in logic that does bold fonts.</li>

<li>implement underlining.</li>
      </ul>
    </li>

<li>patches by Ilya Zakharevich:

        <li>improve drawXtermText() by making the recursive calls
        communicate through arguments, and not through
        saving/restoring global variables.</li>

<li>make double-width characters work with <code>-u8</code>
        option.</li>

<li>modify lookup of double-sized fonts by checking for a

<li>correct configure-script check for imake $CFLAGS, which did
    not check properly if imake was not available.</li>

<li>correct install rule in Makefile.in for
    <code>uxterm</code>, which was attempting to strip the script
    (newsgroup posting by Fernan Aguero).</li>

<li>correct AF/AB strings in termcap for xterm-256color and
    xterm-88color entries (report by Josh Howard).</li>

<li>update wcwidth.c to incorporate changes from Markus Kuhn's
    2003-05-20 (Unicode 4.0) version of that file.</li>

<li>modify <code>scroll-back</code> and
    <code>scroll-forw</code> actions to accept an adjustment value,
    e.g.,

<pre>
              <code>scroll-back(1, page-2)</code>
</pre>to scroll back by 2 lines less than a page (patch by Greg
Klanderman).
    </li>

<li>use color resource setting from Debian package for xterm
    VT100 widget, since the choice of blues provides better
    contrast.</li>

<li>remove color resources from <code>XTerm.ad</code>, leaving
    them only in <code>XTerm-col.ad</code> (prompted by Debian
    package for xterm).</li>

<li>correct configure script option --enable-pty-handshake
    (report by Paul Gilmartin).</li>

    length of time used for visual bell, for very slow displays or
    very fast computers (reports by Ingo van Lil and Doug
    Toppin).</li>

<li>correct logic for initializing dynamic highlight color
    (patch by Jess Thrysoee).</li>

<li>add a check for non-zero size in call to
    <code>XCopyArea()</code> to accommodate a Solaris bug.</li>

<li>correct typo in example for character classes in xterm
    manpage (Debian #198910).</li>

<li>link xterm with bind_on_load option on Darwin to work
    around a deadlock in the dynamic loader when a signal is
    received while the dynamic loader is looking up symbols
    (patches by Rob Braun, Torrey Lyons).</li>

<li>modify configure script to avoid using "head -1".</li>

    process-id rather than a random value.</li>

<li>resync with XFree86 CVS

<ul>
    <li>modify ifdef's for WTMPX_FILE to allow building on cygwin
    again.</li>

<li>change the default of pty-handshaking configure option (and
    related default for imake) to assume this feature is
    needed.</li>

<li>add ifdef's so configure option for XawPlus library works
    (patch by Pavel Roskin).</li>

    Solaris (report by Nelson Beebe).</li>

<li>modify <code>in_put()</code> function to call
    <code>PreeditPosition()</code> only when the cursor's position
    has changed. This addresses report by Stefan Baums of high CPU
    usage while xterm with chinput are running in the background
    (patch by Yong Li).</li>

<li>improved explanation of <code>-ls</code> conflict with
    <code>-e</code> option in xterm manpage (adapted from comments
    by Henning Makholm).</li>

<li>correct comment in terminfo file regarding modifier used
    for <code>kDC</code> (Debian #189764, report by Henning
    Makholm).</li>

<li>correct/extend some of the keypad description in ctlseqs.ms
    (report by Henning Makholm).</li>

<li>correct keypad-mapping table in input.c so
    <code>XK_KP_Equal</code> works (report by Henning
    Makholm).</li>

<li>modified to work with CJK double-width (bi-width/monospace)
    fonts. They're similar to Roman Czbora and David Starner's
    gnuunifonts in that Latin letters and numbers have all the same
    width which is exactly the half of the width of East Asian
    characters. (patch by Jungshik Shin
    &lt;jshin@mailaps.org&gt;).</li>

<li>add configure option <code>--enable-broken-osc</code> and
    resource <code>brokenLinuxOSC</code> to accommodate scripts
    which do not distinguish between running in the Linux console
    and running in X. Linux console recognizes malformed control
    strings which start with an <code>OSC</code>, but are
    fixed-length, with no terminator.</li>

<li>add configure option <code>--enable-broken-st</code> and
    resource <code>brokenStringTerm</code> to allow user to revert
    one part of the parsing table corrections from <a href=
    "#xterm_171">patch #171</a>. (reports by Matthias Scheler and
    Kirill Ponomarew indicate that someone's network firmware sends
    an <code>&lt;escape&gt;X</code>).</li>

<li>modify configure <code>--disable-imake</code> to provide
    values for <code>OSMAJORVERSION</code>,
    <code>OSMINORVERSION</code>, <code>FUNCPROTO</code> and
    <code>NARROWPROTO</code> (report by Heiko Schlichting).</li>

<li>correct <code>vttests/16colors.sh</code>, which omitted the
    <code>$SUF</code> variable in output strings (patch by Paul
    Gilmartin).</li>

<li>modify shell scripts in <code>vttests</code> directory to
    attempt to use named signals in the <code>trap</code>
    statement, making this portable to OS/390 (report by Paul
    Gilmartin). Tested on SunOS 4.1.4, which implements only
    numbers.</li>

<ul>
    <li>add configure option <code>--enable-pty-handshake</code> to
    allow one to compile-in support for the pty handshaking logic,
    and resource <code>ptyHandshake</code> to enable or disable it
    (suggested by Ian Collier).</li>

<li>restore <code>USE_HANDSHAKE</code> ifdef removed in
    <a href="#xterm_159">patch #159</a> to address Debian
    #39964.</li>

<li>move ifdef's for ttysize/winsize into xterm_io.h</li>

<li>simplify loop on <code>tgetent</code>, check if the
    successive entries in the lookup table are the same. That makes
    xterm do one less lookup if there is no "xterm" entry in the
    termcap file (report by Derek Martin).</li>

<li>correct manpage discussion of <code>$TERM</code> and
    <code>$TERMCAP</code> variables, which omitted the Tektronix
    emulation and a note of the final "dumb" fallback.</li>

<li>broaden ifdef for
    <code>XRegisterIMInstantiateCallback()</code> from <a href=
    "#xterm_175">patch #175</a> (XIM fix) to exclude non-XFree86
    (report by Nelson Beebe indicates this breaks for Solaris, IRIX
    and OSF/1).</li>

<li>correct resource-size for <code>iconFont</code> (this was
    added by X11R6.3).</li>

<li>improve configure check for XKB bell extension, to work
    around inconsistent implementation of this feature (reports by
    Nelson Beebe, Kriston Rehberg and David Ellement).</li>

<li>modify configure-check for <code>tty</code> group to be
    less strict in batch mode (report by Nelson Beebe).</li>

<li>modify to allow building with g++, to use its compiler
    warnings (suggested by Nelson Beebe).</li>

<li>modify <code>dec2ucs[]</code> table to reflect newer codes
    available for scanlines 1, 3, 7, 9 (report by Michael

    XIM server, and the XIM server is destroyed (patch by Nam
    SungHyun).</li>

<li>modify to use built-in line-drawing characters for Xft
    fonts (patch by Andrew Tipton).</li>

<li>make menu reflect the state of the <code>tekInhibit</code>
    resource.</li>

<li>make <code>signalInhibit</code> resource work, i.e.,
    disable the menu entries that would send signals to, or exit
    xterm. This was probably broken in X11R5 when logging was
    disabled (report by Sven Mascheck).</li>

<li>changed classes of <code>colorBDMode</code> and similar
    resources that override colors when a video attribute is set to
    <code>ColorAttrMode</code>, to make them distinct from
    <code>ColorMode</code>. This avoids an unexpected rendering of
    reverse video, for example (report by Paul Fox).</li>

<li>changed class of <code>veryBoldColors</code> to
    <code>VeryBoldColors</code>, since <code>ColorMode</code> is
    associated with boolean resources.</li>

<li>add option <code>-k8</code> and resource
    <code>allowC1Printable</code> to allow users of non-VTxxx
    character sets such as KOI-8 to treat the C1 control area
    (character codes 128-159) as printable rather than control
    characters.</li>

<li>add a null-pointer check for return-value of
    <code>ptsname()</code> in HPUX-specific code (report by David
    Ellement).</li>

<li>revise the ifdef's used for <code>XKB</code> bell support.
    The code was using a nonstandard call
    <code>XkbStdBell()</code>. Changed to use
    <code>XkbBell()</code> (based on patch by
    &lt;derek@signalmarketing.com&gt;).</li>

<li>add a null-pointer check in <code>xtermLoadFont()</code> in
    case there is no wide-bold font (Nam SungHyun).</li>

<li>change <code>Makefile.in</code> to use autoconf's
    <code>bindir</code>, <code>libdir</code> and
    <code>mandir</code> variables (report by Nam SungHyun).</li>

<li>add <code>le</code> to termcap <code>xterm-basic</code>
    entry. Though missing from older termcaps for xterm, some
    applications check for it (report by Matthias Buelow).</li>

<li>modify <code>uxterm</code> script to strip modifiers such
    as "@euro" from the locale setting before adding ".UTF-8"
    (Debian #179929).</li>

<li>modify the remaining places where tek4014 emulation uses
    <code>XDefineCursor()</code>, to make it work as originally
    implemented, e.g., when switching back to alpha mode. Added
    test-screen in vttest to test this feature properly.</li>

    <code>XDefineCursor()</code> on a shell-window no longer work.
    The tek4014 emulation used this. Use the next lower window
    (report by Karl Rudolf Bauchspiess).</li>

<li>add a resource setting <code>allowWindowOps</code> to
    control whether the extended window operations should be

<li>merge <code>Error()</code> calls and some
    <code>exit()</code> calls into <code>SysError()</code>, and
    change that to add the brief explanation for each error code
    which is provided in the manpage. Change a few
    <code>SysError()</code>, calls to avoid using code 1, to avoid
    confusion with exit status from places that do not use
    <code>SysError()</code>.</li>

<li>simplify logic used to open a debug logfile as the standard
    error.</li>

<li>modify the <code>-e</code> option so that if it fails,
    xterm will check if only one argument follows, e.g., it was
    quoted, and then retry using <code>sh&nbsp;-c</code>.</li>

<li>modify parsing of DECUDK string parameter to allow a comma
    between pairs of hexadecimal digits (Ray Neuman
    &lt;raymond@one.com.au&gt; reports that "real" terminals accept
    this; perhaps they simply ignore unexpected characters).</li>

<li>fix a few problems with the <code>$TERMCAP</code> string
    generated by <code>resize</code>:

<ul>
        <li>for Bourne shell, add an <code>export</code> command.
        This was missing as far back as X11R5.</li>

<li>escape exclamation marks, used in xterm's reset
        string.</li>

<li>translate literal <code>\177\</code> to "^?".</li>

    </li>

<li>improve configure check for <code>tgetent()</code> to work
    when <code>$TERMCAP</code> has been set to a specific

<li>modify <code>minstall.sh</code> to use "%" rather than "@",
    to avoid problems with AFS (report by Zdenek Sekera).</li>

<li>list fatal error codes from <code>error.h</code> in the
    manpage, remove unused codes in <code>error.h</code>.</li>

<li>use more explicit wording for manpage list of color
    resources, since at least one user confused the generic names
    such as "black" with the names in rgb.txt (the latter are now

<h1><a name="xterm_167" id="xterm_167">Patch #167 - 2002/8/24 -
  XFree86 4.2.0</a></h1>

<ul>
    <li>correct ifdef's for <code>USE_TERMCAP</code> to match
    cygwin configuration.</li>

<li>fix several places in ctlseqs.ms which had no boxes around
    the literal text (report by Ilya Zakharevich).</li>

<li>extend mouse support for readline, ifdef'd with
    OPT_READLINE (integrated patch from Ilya Zakharevich).</li>

<li>modify terminfo description to match default for
    <code>modifyCursorKeys</code> resource.</li>

<li>add <code>modifyCursorKeys</code> resource to control how
    the shift- and similar modifiers are used to make a cursor
    escape sequence. The default makes a modified escape sequence
    always start with CSI and puts the modifier as the second
    parameter, to avoid confusing applications that would interpret
    the first parameter as a repeat count. The original behavior
    can be obtained by setting the resource to 0 (newsgroup
    discussion with Stephen J Turnbull, Jeffrey Altman).</li>

<li>correct missing initializations for
    <code>appdefaultCursor</code> and <code>appdefaultKeypad</code>
    resources.</li>

<li>add configure option <code>--enable-luit</code> and ifdef'd
    the luit-related code with OPT_LUIT_PROG.</li>

<li>modify xterm to invoke luit (integrated patch by Tomohiro
    Kubota)</li>

<li>update wcwidth.c to match Markus Kuhn's 2002-05-18
    version.</li>

<li>correct limit-checking in <code>ComputeSelect()</code> to
    handle selections that extend off the visible area; rather than
    modify the parameters to <code>TrackText()</code>, use
    <code>ScrollSelection()</code> to update the highlighting
    limits. (reported by Yegappan Lakshmanan and Nelson Beebe,
    patch by Alexander V Lukyanov).</li>

<li>correct manpage description of <code>tiXtraScroll</code>
    resource (reported by Tony Finch).</li>

<li>changes from OpenBSD:

<ul>
        <li>Make xterm setgid utmp to be able to update utmp even
        with root privileges revoked.</li>

<li>If not updating utmp, revoke group privileges totally
        too.</li>
      </ul>
    </li>

<li>changes from NetBSD:

<ul>
        <li>Check that the return value from ttyslot() is greater
        than 0 before writing the utmp file. Fixes w's "w: Stale
        utmp entry: &lt;user&gt; &lt;tty&gt; &lt;pty&gt;"
        errors.</li>

<li>Use openpty() to deal with new pty naming scheme.</li>
      </ul>
    </li>

<li>add <code>print-redir</code> action and menu entry to allow
    user to switch terminal in/out of printer controller mode. It
    appears from the manual that a real vt220 would not switch back
    to normal mode, so another mechanism is used (addresses Debian
    #37517).</li>

<li>check if <code>printerCommand</code> resource string is
    empty, use this to allow user to disable printer function.</li>

<li>trim trailing blanks from resource strings.</li>

<li>check return value from <code>ptsname()</code>, which may
    return null for example if someone has changed the permissions
    of /dev/pts to zero (Debian #121899).</li>

<li>modify OS/2 version to use <code>__UNIXOS2__</code>
    definition rather than <code>__EMX__</code>, related cleanup
    (patch by Holger Veit).</li>

<li>used modified indent 2.0 (patch <a href=
    "ftp://ftp.invisible-island.net/gnu-patches/">20020428</a>) to
    reformat most of the C source files, to simplify
    maintenance.</li>

<li>fix a couple of places where there were leading tabs on
    symbol-definition lines in Imakefile (Marc La France from
    report by Tony Finch)</li>

<li>add imake variable (TraceXTerm) to allow building debug
    version (Egbert Eich).</li>

        from the 1996 version from X Consortium, does not
        incorporate changes made by X Consortium or The Open Group

<li>add configure check for <code>&lt;ncurses/term.h&gt;</code>
    to get rid of hardcoded <code>__CYGWIN__</code> ifdef in
    resize.c

<p>NOTE: The CYGWIN port should not be linking
      <code>resize</code> with ncurses. It appears that the only
      reason it is, is because both the ncurses and termcap ports
      on that platform are badly misconfigured (essential pieces
      have been removed, etc). Checking for

<ul>
    <li>augment key translations for scrollbar widget to ensure
    that keystrokes intended for the text area are not lost if the
    mouse pointer happens to fall on the scrollbar. This can
    happen, for instance, if the user's <code>app-defaults</code>
    or <code>.Xdefaults</code> file contains a translations
    resource, though it may also happen through unrelated resource
    settings: probably a bug in libXt (reported by Paul Fox
    &lt;pgf@foxharp.boston.ma.us&gt; and Dmitry Yu. Bolkhovityanov
    &lt;D.Yu.Bolkhovityanov@inp.nsk.su&gt;).</li>

<li>widen ifdef's in xterm.h to define
    <code>__EXTENSIONS__</code> on Solaris, for compilers other
    than gcc. This was added along <code>_POSIX_C_SOURCE</code>
    with in <a href="#xterm_151">patch #151</a>, but is not
    sufficient since Sun's compiler does not define
    <code>__STDC__</code> by default (report by Matthias Scheler
    &lt;tron@zhadum.de&gt;).</li>

<li>modify xterm to obtain the closest matching color if an
    exact color is not available, e.g., on 8-bit displays (patch by
    Stephen P Wall)</li>

<li>implement "OverTheSpot" preedit type of XIM input (patch by
    Tomohiro Kubota):

<ul>
        <li>This preedit type is a reasonable compromise between
        simpleness of implementation and usefulness. "Root" preedit
        type is easy to implement but not useful; "OnTheSpot"
        preedit type is the best in the point of view of user
        interface but very complex. And more, "OverTheSpot" is the
        preedit type which the most XIM servers support. Thus, to
        achieve reasonable usability, support of "OverTheSpot"
        preedit type is needed.</li>

<li>In "OverTheSpot" preedit type, the preedit
        (preconversion) string is displayed at the position of the
        cursor. On the other hand, it is XIM server's
        responsibility to display the preedit string. Thus, it is
        needed for XIM client (here XTerm) to inform the XIM server
        of the cursor position. And more, to achieve good visual
        proportion, preedit string must be written using proper
        font. Thus, it is XIM client's responsibility to inform the
        XIM server of the proper font. The font must be supplied by
        "fontset". Fontset is a set of fonts with charsets which
        are specified by the current locale. Since XTerm uses
        ISO10646 fonts regardless of the current locale, the fonts
        for XIM must be prepared separately. It is difficult to
        prepare fonts which are similar to XTerm font. Thus, my
        patch uses a simple way - the default font is "*" which
        matches every fonts and X library will automatically choose
        fonts with proper charsets. I added "-fx" command option
        and "ximFont" resource to override this default font
        setting.</li>

<li>changed the definition of "OverTheSpot" preedit type
        from XIMPreeditPosition|XIMStatusArea to
        XIMPreeditPosition|XIMStatusNothing. This matches the
        behavior of other programs such as Rxvt, Kterm, Gedit.</li>

<li>A tiny XIM bugfix is also included. By calling
        XSetLocaleModifiers() with parameter of "", it can consider
        XMODIFIERS environmental variable which is a standard way
        for users to specify XIM server to be used.</li>
      </ul>
    </li>

<li>adjust configure script to accommodate repackaging of
    keysym2ucs.c as include-file for xutf8.c (patch by Tomohiro
    Kubota).</li>

<li>add the <code>UXTerm</code> app-defaults file to makefile
    install rules (request by Juliusz Chroboczek).</li>

<li>correct logic in <code>get_termcap()</code>, which returned
    false if the <code>tgetent()</code> call indicated that xterm
    was linked with terminfo. Although the <code>$TERMCAP</code>
    variable cannot be adjusted in this case, xterm still needs
    information from this call to extract data to initialize the
    erase-mode when the <code>ptyInitialErase</code> resource is
    false.</li>

<li>modify <code>ScrollbarReverseVideo()</code> function to
    cache the original border color, so it can restore that when an
    application flashes the screen (Bugzilla #38872).</li>

<li>resync with XFree86 CVS

<ul>
        <li>remove ifdef's for X_NOT_STDC_ENV (patch by David

<h1><a name="xterm_157" id="xterm_157">Patch #157 - 2001/6/18 -
  XFree86 4.1.0</a></h1>

<ul>
    <li>clean up button.c and input.c (patch by Juliusz
    Chroboczek). The basic idea is to use a single set of APIs in
    the XTerm core, and put a set of workarounds in a separate
    file. As you will notice, this drastically simplifies parts of
    the code; in particular, the only remaining ifdefs related to
    the differences between Xutf8 and legacy systems are related to
    the selection provider logic. This defines two new files,
    xutf8.h and xutf8.c, provide some half-hearted but fully
    portable emulation for the three Xutf8* functions that XTerm
    uses. Putting these in a separate file will allow people to
    experiment with more complex versions without making the core
    of XTerm more difficult to maintain. The functionality of the
    emulation is as follows.

<ul>
        <li>Xutf8TextListToTextProperty fully handles XStringstyle
        and XUTF8StringStyle. It will only generate STRING for
        XStdICCTextStyle, and will only generate Latin-1 in
        XCompoundTextStyle (but label it as COMPOUND_TEXT, as the
        spec requires). (I have hesitated to make this function
        fail for XStdICCTextStyle and XCompoundTextStyle; this
        might be a smart thing to do, in the hope that the
        selection requestor will try UTF8_STRING afterwards;
        opinions?)</li>

<li>Xutf8TextPropertyToTextList fully handles STRING and
        UTF8_STRING. It systematically fails for
        COMPOUND_TEXT.</li>

<li>Xutf8LookupString will properly handle single-keystroke
        input for the keysyms covered by Markus' keysym2ucs
        function. It will not handle either compose key input or
        external input methods.</li>
      </ul>
    </li>

<li>add an ifdef for <code>SunXK_F36</code>, used in
    <code>xtermcapKeycode()</code> (patch by Mark Waggoner
    &lt;waggoner@ichips.intel.com&gt;).</li>

<li>modify check for login name to try <code>getlogin()</code>
    and $LOGNAME, $USER environment variables to detect if the user
    has logged in under an alias, i.e., an account with the same
    user id but a different name (Debian bug report #70084).</li>

<li>add resource <code>tiXtraScroll</code>, which can be used
    to preserve the screen contents in the scrollback rather than
    erasing it when starting a fullscreen application such as
    <code>vi</code> (patch by Ken Martin
    &lt;fletcher@catsreach.org&gt;).</li>

<li>two patches by Denis Zaitsev &lt;zzz@cd-club.ru&gt;:

<ul>
        <li>added <code>forceBoxChars</code> resource to control
        the "line-drawing characters" option.</li>

<li>added <code>freeBoldBox</code> resource, which, when
        set true, suppresses check in
        <code>same_font_size()</code>, so xterm does not attempt to
        ensure that the bold font is the same size as the normal
        font.</li>
      </ul>
    </li>

<li>change the color class for ANSI colors and similar ones
    such as bold-color, etc., to follow the convention that the
    classname is the instance name with a leading capital (e.g.,
    <code>color0</code> and <code>Color0</code> rather than
    <code>color0</code> and <code>Foreground</code>). There was
    little use for Foreground as a class other than to create
    occasional confusion and bug reports, most recently by Nelson
    Beebe who reports that it disables colors in xterm but not on
    Linux, which is probably due to a difference in resource
    evaluation order. A configure script option
    (--disable-color-class) is provided for anyone who did use the
    older behavior.</li>

<li>fix a signal-handling bug. When running xterm with
    <code>ksh</code> or similar shell such as bash 2.05, xterm will
    hang and not respond to keystrokes after the user types
    <code>suspend</code>. Additionally the popup menus do not
    respond, so it is not possible to send SIGCONT to the shell.
    What is happening is that the shell is sending itself SIGSTOP,
    and it is being stopped. Per specification it also means that
    the operating system is sending SIGCHLD to parent to the bash
    (XTERM). Now the issue is that xterm assumes it cannot happen
    and it expects to receive SIGCHLD only upon
    <em>termination</em> of its children. This causes a deadlock
    with xterm waiting for the child to die, and the child waiting
    for SIGCONT. (report/patch by Adam Sulmicki), analysis/testing

<h1><a name="xterm_151" id="xterm_151">Patch #151 - 2001/3/10 -
  XFree86 4.0.2</a></h1>

<ul>
    <li>alter the behaviour of selections in XTerm (patch by
    Juliusz Chroboczek). It is believed to follow the ICCCM +
    UTF8_STRING to the letter, both in UTF-8 and in eight-bit mode.
    From his description:

<ul>
        <li>When compiled against XFree86 4.0.2, the patched XTerm
        will make the selection available as COMPOUND_TEXT, STRING
        or UTF8_STRING in both modes. It will request selections in
        the following order:

<p>UTF-8 mode: UTF8_STRING, TEXT, COMPOUND_TEXT,
          STRING.<br>
          eight-bit mode: TEXT, COMPOUND_TEXT, UTF8_STRING,
          STRING.</p>
        </li>

<li>When compiled against an earlier version of XFree86 (or
        compiled with OPT_UTF8_API=0), it will still obey the
        ICCCM, but will neither request nor provide UTF8_STRING in
        eight-bit mode, and neither TEXT nor COMPOUND_TEXT in UTF-8
        mode.</li>

<li>For compatibility with previous versions of XTerm, a
        resource <code>i18nSelections</code> is provided, please
        see the manpage for details. However, due to an unexpected
        combination of ICCCM extensions by various bits and pieces
        of the libraries, interacting with previous versions of
        XTerm will work in many locales even without this flag.
        (Please do not set this resource to true by default, as
        this would violate the ICCCM.)</li>
      </ul>
    </li>

<li>improved error checking/reporting in VTInitI18N(), ensuring
    that lack of input method styles is treated distinctly from a
    mismatch.</li>

<li>remove an incorrect ifdef from patch #141 which suppressed
    overstriking to simulate bold font when xterm was compiled to
    support wide characters (report/analysis by Adam M Costello
    &lt;amc@cs.berkeley.edu&gt;, Debian #76404, Debian
    #77575).</li>

<li>modify <code>RequestResize()</code> function to
    save/restore window manager hints. Its call to
    <code>XtMakeResizeRequest()</code> had the undesirable
    side-effect of clearing window manager hints, e.g., when
    switching to 132-columns via DECCOLM escape sequence. Window
    manager hints make it simple to resize xterm in terms of
    character cells rather than pixels (reports by Christian
    Weisgerber, Debian #79939).

<p>This applies to the normal configuration. When built with
      toolbar support, the hints are applied to a different widget
      level (more work will be needed to make hints work with the
      toolbar).</p>
    </li>

<li>fix a redefinition warning for resize.c on OpenBSD (patch
    by Christian Weisgerber).</li>

<li>change resource corresponding to <code>-T</code> option to
    match Xt library's <code>-title</code>, i.e.,
    <code>.title</code> rather than <code>*title</code> so the
    command-line options are interchangeable as documented (Debian
    bug report #68843).</li>

<li>add script used from autoconf'd makefile for installing
    manpages, since recent XFree86 changing the way section numbers
    are represented makes the install dependent on extra
    scripts.</li>

<li>add configure check for freetype libraries and configure
    option --disable-freetype to override this feature.</li>

<li>modify some configure script macros to avoid using
    changequote(), which has been rendered useless in the latest
    autoconf alpha 2.49c</li>

<li>update config.guess, config.sub to 2001-2-13</li>

<li>remove redundant/contradictory __CYGWIN__ definitions from
    resize.c</li>

<li>correct manpage typo introduced by X11R6.5 resync.</li>
  </ul>

<p>Changes from XFree86 4.0.2:</p>

<ul>
    <li>add definition of <code>_POSIX_C_SOURCE</code> for Solaris

  </ul>

<h1><a name="xterm_150" id="xterm_150">Patch #150 - 2000/12/29 -
  XFree86 4.0.2</a></h1>

<ul>
    <li>move the binding for shifted keypad plus/minus, which
    invokes the <code>larger-vt-font()</code> and
    <code>smaller-vt-font()</code> actions, respectively, into the
    translations resource (suggested by Marius Gedminas
    &lt;mgedmin@puni.osf.lt&gt;).</li>

<li>modify configure script to support the
    <code>--program-prefix</code>, <code>--program-suffix</code>
    and <code>--program-transform-name</code> options (request by
    Alison Winters &lt;alison@mirrabooka.com&gt;).</li>

<li>fixes for wide/combining characters (Robert Brady):

<ul>
        <li>fix a scrolling / combining characters display
        anomaly</li>

<li>fix a problem with double-width characters where if the
        primary font had no box-drawing characters, the right hand
        half of double-width characters was erased (reported by Yao
        Zhang &lt;yzhang@sharemedia.com&gt;).</li>

<li>fix special case of null byte for key handling in UTF-8
        locales.</li>
      </ul>
    </li>

<li>modify logic that compares sizes of normal and bold fonts
    to be more forgiving of the font server's choice of bold font
    which must match the normal font's size. Now
    <code>same_font_size()</code> compares the height of the fonts
    rather than individually ascent and descent, and allows the
    bold font to be one pixel smaller than the normal font
    (addresses a report by Alan Citterman &lt;alan@mticket.com&gt;,
    who says that something in patches #146 to #148 made xterm more
    likely to overstrike bold fonts, and indirectly Debian bug
    report #76404, which reports the opposite).</li>

<li>make configure script use $CFLAGS and $CPPFLAGS
    consistently, including removing a chunk from configure.in
    which attempted to save/restore $CPPFLAGS while processing
    value set by the --x-includes option, but lost values set in an
    intervening AC_CHECK_HEADERS. This change modifies macros
    CF_ADD_CFLAGS, CF_ANSI_CC_CHECK and CF_X_TOOLKIT, as well as
    removing variables IMAKE_CFLAGS and X_CFLAGS from the generated
    makefile (the AC_CHECK_HEADERS problem was reported by Albert
    Chin-A-Young &lt;china@thewrittenword.com&lt;).</li>

<li>correct a comparison in SELECTWORD case of ComputeSelect(),
    which resulted in a word-selection wrapping past the first
    column without checking the first column's character class
    (reported by Christian Lacunza
    &lt;celacunza@netscape.net&gt;</li>

<li>correct a logic in UTF-8 mode for selecting double-width
    characters; a combining character was omitted (patch by Markus
    Kuhn).</li>

<li>add feature to pop (raise) window when a bell is received
    (patch by Gael Roualland
    &lt;gael.roualland@dial.oleane.com&gt;).</li>

<li>add __NetBSD__ and __OpenBSD__ to special-case in
    xterm_io.h for USE_POSIX_TERMIOS definition (patch by Christian
    Weisgerber).</li>

<li>move special-case HPUX include for &lt;sys/bsdtty.h&gt; to
    xterm_io.h to define TIOCSLTC, making HAS_LTCHARS defined for
    HPUX 10.20 (report by Bruno Betro).</li>

    <code>termio.h</code> and related definitions for main.c,
    os2main.c, screen.c and resize.c so they will share equivalent
    definitions in a new header <code>xterm_io.h</code>. This is

    arise from inconsistent definitions for SIGWINCH- and
    HAS_LTCHARS-related symbols (reports by Bruno Betro, Jeremie
    Petit and Clint Olsen).</li>

<li>improve usability of double-width fonts by allowing normal
    fonts to be given as double-width (from a patch by Fabrice
    Bellard &lt;bellard@email.enst.fr&gt;).</li>

<li>correct a few compiler warnings in TRACE() macros for
    signed/unsigned variable differences (reported by Clint
    Olsen).</li>

<li>make configure script use $CFLAGS and $CPPFLAGS more
    consistently, i.e., by using CF_ADD_CFLAGS in CF_ANSI_CC

<li>expanded description of environment variables in

<li>modify OPT_TCAP_QUERY feature to always return the termcap

        <code>-fwb</code> or with resource
        <code>wideBoldFont</code> (class
        <code>WideBoldFont</code>).</li>

<li>some changes to align terminfo with ncurses 5.2:

<ul>
        <li>remove xtermm description, retaining xterm-mono since
        the former conflicts with ncurses.</li>

<li>modify initialization and reset strings to avoid
        putting the save/restore cursor operations bracketing
        changes to video attributes, since the changes could be
        lost when the cursor is restored. This affects xterm-r6 and
        xterm-8bit (the xterm-xfree86 entry uses the soft-reset
        feature which resets scrolling margins and origin mode
        without requiring us to save/restore the cursor
        position).</li>

<li>make a few entries explicitly inherit from
        xterm-xfree86 rather than xterm: xterm-rep, xterm-xmc,
        xterm-nrc</li>
      </ul>

<li>ensure that sign-extension does not affect
    <code>ctype</code> macros by using <code>CharOf()</code> macro
    to coerce the parameter to an unsigned char.</li>

<li>resync with XFree86 4.0.1d:

<ul>

<ul>
    <li>correct implementation of <code>ptyInitialErase</code>: the
    value assigned to <code>initial_erase</code> was for the
    control terminal, which is correct as far as it goes. But there
    was no following test for the pseudo-terminal's erase value,

  XFree86 4.0.1b</a></h1>

<ul>
    <li>remove a spurious assignment in ScreenWrite() from Robert
    Brady's patch which set a null at the "end" of the buffer to be
    written. That made the autowrap feature write a blank in the
    first column for the non-UTF-8 configuration, rather than the
    actual character (reported by Alan Citterman
    &lt;alan@mticket.com&gt;).</li>

<ul>
    <li>changes for doublewidth and combining characters, from
    http://www.ecs.soton.ac.uk/~rwb197/xterm/ (integrated patch by
    Robert Brady). In this context, doublewidth refers to 16-bit
    character sets which may have glyphs occupying two cells.</li>

<li>add command-line option <code>-class</code>, which allows
    one to override xterm's resource class. Also add resource file
    <code>UXTerm.ad</code>, which simplifies using xterm for both
    8-bit character sets and UTF-8.</li>

  XFree86 4.0.1</a></h1>

<ul>
    <li>modify Makefile.in to circumvent GNU make's built-in suffix
    rule for ".sh" which confuses install.sh with the "make
    install" target (report/patch by Paul Gilmartin).</li>

<li>implement an experimental control sequence which an
    application may use to query the terminal to determine what
    sequence of characters it would send for a given function key.
    This is ifdef'd with OPT_TCAP_QUERY (request by Bram
    Moolenaar).</li>

<li>add /usr/local to search path in CF_X_ATHENA configure
    macro to build with Xaw3d on OpenBSD (patch by Christian

<li>add missing <code>#undef HAVE_TERMIO_C_ISPEED</code> to
    xtermcfg.hin, omitted in patch #133 fix for IRIX 6.5 baudrate
    (report by Alain Filbois &lt;Alain.Filbois@loria.fr&gt;).</li>

<li>correct a few errors in xterm.man: font in filename example
    for Tektronix emulation, and description of -nul/+nul
    command-line options (report by Eric Fischer

<ul>
    <li>back out change to <code>-name</code> command-line option,
    restoring its original behavior (as noted by David Madore, the
    correct interpretation of this option is the application
    instance rather than the application class).</li>
  </ul>

<h1><a name="xterm_138" id="xterm_138">Patch #138 - 2000/6/15 -
  XFree86 4.0c</a></h1>

<ul>
    <li>workaround for fixed fonts which are generated from Unicode
    fonts: they omit glyphs for some xterm's less-used line-drawing
    characters, which caused xterm to set a flag telling it to use
    only its internal line-drawing characters. Do not set the flag
    (it can be set from the popup menu), and xterm will generate
    only the line-drawing glyphs which actually are missing.<br>
    Otherwise, when used for large fonts, xterm may generate a
    2-pixel wide line, which can leave dots on the screen.</li>

<li>restore first line of 256colres.pl, omitted in 4.0c

  XFree86 4.0b</a></h1>

<ul>
    <li>make command-line <code>-name</code> option work as
    documented. Apparently this was lost in X11R5 when coding to
    use <code>XtAppInitialize</code>.</li>

<li>limit numeric parameters of control sequences to 65535 to
    simplify checks for numeric overflow.</li>

<li>change index into UDK list to unsigned to guard against
    numeric overflow making the index negative (Taneli Huuskonen
    &lt;huuskone@cc.helsinki.fi&gt;).</li>

<li>change <code>sun&nbsp;function-keys</code> resource name to
    <code>sunFunctionKeys</code> to work around redefinition of the
    token <code>sun</code> by xrdb on Solaris. Similarly, renamed
    resource <code>sun&nbsp;keyboard</code> to
    <code>sunKeyboard</code> (Stephen P Wall).</li>

<li>change similar resource names for HP and SCO to avoid
    potential conflict with xrdb symbols on other systems, as well
    as for consistency.</li>

<li>reorganized the install targets in the autoconf'd Makefile,
    adding install-app, install-bin, install-dirs and install-man.
    The app-defaults class can be overridden by setting the make
    variable 'CLASS', simplifying customization of xterm as a
    Unicode terminal, e.g., CLASS=UXTerm.</li>

<li>add limit checks to <code>ClearInLine()</code>,
    <code>ScrnInsertChar()</code>, <code>ScrnDeleteChar()</code> to
    correct potential out-of-bounds indexing (prompted by Debian
    bug report #64713, which reported a problem with ICH escape
    sequences).</li>

<li>updates to config.sub and config.guess Kevin Buettner
    &lt;kev@primenet.com&gt; for elf64_ia64 Bernd Kuemmerlen
    &lt;bkuemmer@mevis.de&gt; and MacOS X.</li>

    open /dev/tty when there is no controlling terminal (patch by
    Paul Gilmartin).</li>

<li>fixes for building on Digital Unix 4.0 and AIX 4.2 (patch
    from H Merijn Brand &lt;h.m.brand@hccnet.nl&gt;).</li>

<li>minor correction to format of updated $TERMCAP when adding
    <code>kb</code> capability for <code>ptyInitialErase</code>
    logic.</li>

  </ul>

<h1><a name="xterm_134" id="xterm_134">Patch #134 - 2000/5/28 -
  XFree86 4.0b</a></h1>

<ul>
    <li>update URL's and mailing addresses, moved to
    http://dickey.his.com and dickey@herndon4.his.com</li>

<li>correct missing quotes in CF_TTY_GROUP configure script
    macro in case the script is run in batch mode.</li>

<li>modify ownership-check of log file to ignore the group
    ownership. Otherwise xterm cannot create logfiles in
    directories with set-gid permissions.</li>

<li>simplify the logic that reads termcap data.</li>

<li>add fallback definition for B9600 in case line speed
    definition for 38400 is missing (report by Jack J Woehr
    &lt;jwoehr@ibm.net&gt;, for OpenBSD 2.6).</li>

<li>fix: Set highlightColor, and select a region containing the
    text cursor. If the window loses focus, the cursor becomes
    hollow, with the region inside the cursor being
    background/foreground, unlike the rest of the selection, which
    is foreground/highlight (patch by Ross Paterson
    &lt;ross@soi.city.ac.uk&gt;).</li>

<li>add configure script tests to define SVR4, SYSV and
    USE_POSIX_WAIT, which enables xterm to compile on Solaris 7 and
    SCO Openserver without imake, though there are still a few
    features for the latter which require <code>sco</code> to be
    predefined.</li>

<li>patches from Stephen P Wall:

<ul>
        <li>add support for two Sun-specific function keys. These
        keys are labeled F11 and F12 on Sun Type 5 keyboards, but
        return SunXK_F36 and SunXK_F37. Support will only be
        compiled in if the header file &lt;X11/Sunkeysym.h&gt;
        exists and contains the appropriate symbol definitions. The
        keycodes for the DEC keycodes were arbitrary unused codes,
        but the ones for the Sun keycodes are what cmdtool and
        shelltool actually send.</li>

<li>add <code>colorRV</code> and <code>colorRVMode</code>
        resources to allow specifying a color to use for reverse
        video, similar to the existing UL, BD, and BL modes.</li>

<li>add <code>alwaysUseMods</code> resource, to override
        check if <code>alt</code> or <code>meta</code> modifiers
        are used in <code>translations</code> resource. Revamped
        the code to calculate the modifier value, and included Meta
        if alwaysUseMods is TRUE, using values 9-16.</li>
      </ul>
    </li>

<li>fixes for os390 (Paul Gilmartin):

<ul>
        <li>regularize the definition of CONTROL() and remove an
        acknowledged "trial and error" table.</li>

<li>translate "^?" into A2E(0177) which is the EBCDIC "DEL"
        rather than plain 0177 which is the EBCDIC quotation
        mark.</li>

<li>modify <code>xtermMissingChar()</code> so that EBCDIC
        codes 128-159 are not rendered as blanks by X server
        running on Solaris, which sees those as control
        characters.</li>

<li>make debugging traces (configure --enable-trace) work
        properly with EBCDIC.</li>
      </ul>
    </li>

  XFree86 4.0a</a></h1>

<ul>
    <li>add substitutions in autoconf'd Makefile for CPPFLAGS,
    LDFLAGS and AWK (reported by Neil Bird).</li>

<li>correct uninitialized <code>childstat</code> variable from
    patch #131 in <code>creat_as()</code> function, which caused
    logging to not work on Solaris, whose <code>waitpid()</code>
    function does not initialize its parameter. Add check for EINTR
    on return from <code>waitpid()</code> as well (reported by Neil
    Bird &lt;neil.bird@rdel.co.uk&gt;).</li>

<li>remove a redundant check for working <code>setuid()</code>
    function introduced in patch #132. Greg Smith reports that this
    does not work as intended on os390.</li>

<li>change line speed from 9600bd to 38400bd, to accommodate
    people who mistakenly use $TERM set to <em>vt100</em>, to
    reduce the effect of padding associated with this terminal
    type.</li>

<li>add configure script check for IRIX 6.5's redefinition of
    baud rates associated with <code>struct termio</code>, to
    correct a situation where the baud rate was initialized to zero
    (reported by Andrew Isaacson &lt;adi@lcse.umn.edu&gt;).</li>

    (analysis by D Roland Walker).</li>

<li>add ctrlFKeys resource, replacing constant for adjusting
    control-F1 to control-F12 to VT220-style F10-F20. The resource
    changes the constant 12 to a default value of 10 (request by
    Jim Knoble &lt;jmknoble@pobox.com&gt;).</li>

<li>correct ifdef'ing for conflict between definitions in AIX's
    &lt;sys/select.h&gt; and &lt;X11/Xpoll.h&gt; (reported by Clint
    Olsen).</li>

<li>add checks for return-values of getutid(), initgroups() and

    include tty-group and WTMP logic (adapted from patch by Paul
    Szabo &lt;psz@maths.usyd.edu.au&gt;)</li>

<li>modify resize.c to build and work on os390 (uses EBCDIC)

<ul>
    <li>improve logfile security (integrated patch by Branden
    Robinson)

<ul>
        <li>make the <code>creat_as()</code> function more strict
        by using O_EXCL rather than O_APPEND.</li>

<li>fixes to make DEBUG ifdef's compile/run, including
        making the debug logfile more unique by appending a
        timestamp to its name.</li>

<li>include &lt;term.h&gt; in resize.c, to fix a
        missing-prototype warning.</li>
      </ul>
    </li>

<li>modified <code>creat_as()</code> a little more, retaining
    the ability to append to a logfile If the user specifies the
    name. Also, check if the opened file (which patch #130 ensures
    is owned by the effective user) is not writable by other
    users.</li>

<li>use <code>creat_as()</code> logic to make tek4014
    screen-copy more secure (noted by Branden Robinson).</li>

<li>ifdef'd some of Branden's changes to build/work on older
    machines.</li>

<li>correct missing initialization of the <code>.mode</code>
    flag in <code>ColorRes</code> struct, from patch #129. This
    worked on Linux because <code>malloc()</code> zeroes memory on
    that platform (reported by Christian Weisgerber).</li>

<li>modify logic for <code>deleteIsDEL</code> resource so it
    has internally 3 states: unspecified, true and false. If
    unspecified, the keyboard type determines whether the Delete
    key transmits <code>&lt;ESC&gt;[3~</code> or <code>\177</code>,
    and the popup menu entry reflects the internal state.
    Otherwise, the popup menu entry overrides the keyboard type
    (suggested by Dr Werner Fink, to make it simpler to set
    resources that imitate the legacy X11R6 xterm).</li>

<ul>
    <li>modify <code>scroll-forw()</code> and
    <code>scroll-back()</code> actions, adding a third parameter
    which will direct xterm to ignore the action when mouse
    reporting is enabled. This is needed for the wheel mouse to be
    used to report to the application rather than scroll the
    window.</li>

<li>add menu entry and action to allow disabling xterm's
    assumption that the current font contains line-drawing
    characters if the font cells 1-31 are nonempty. Some fonts may
    have other characters (reported by Bruno Betro
    &lt;bruno@iami.mi.cnr.it&gt;).</li>

<li>add a check in <code>creat_as()</code> to ensure that the
    user really owns the logfile that has been opened.</li>

<li>add logic to implement SCO function-keys. (This is really
    incomplete, since I intend to revisit this and make xterm able
    to emulate scoansi better than just the function-keys).</li>

<li>add configure script option --enable-sco-fkeys, minor
    related fixes (patch by Dr Werner Fink).</li>

<ul>
    <li>change coding of editing keypad's "Delete" key to
    &lt;escape&gt;[3~, in the default (Sun/PC) keyboard mode. This
    makes the terminfo kdch1 capability independent of the coding
    of the backarrow key, which sends either backspace (8) or DEL
    (127). The reason for doing this (compatibility with the
    <em>screen</em> program) outweighs the choice of DEL (127)
    which was used in X11R5/X11R6 xterms. The <em>screen</em>
    program translates whatever matches kdch1 into
    &lt;escape&gt;[3~, even if it happens to be the stty erase
    character.</li>

<li>add encoding for control/?, to work around xmodmap or key
    translations which may confuse backspace and delete. A
    control/? will send DEL (127), and a control/H will of course
    send backspace (8).</li>

<li>add encoding for kcbt to &lt;escape&gt;[Z (fixes Debian
    #54840).</li>

<li>minor correction to logic that encodes Sun and DEC function
    keys to avoid sending an escape sequence if the key symbol is
    not found in xterm's lookup table.</li>

<li>simplify ifdef's in main.c for POSIX VDISABLE so the "^-"
    pattern is more likely to be implemented when <em>imake</em>
    configures xterm (fixes Debian #55105).</li>

        problems.</li>
      </ul>
    </li>
  </ul>

<h1><a name="xterm_122" id="xterm_122">Patch #122 - 1999/12/28 -
  XFree86 3.9.16f</a></h1>

<ul>
    <li>move the suggested wheel-mouse button translations into
    charproc.c to simplify customization. Correct some minor logic
    errors in the support for buttons 4 and 5, used for wheel mice
    (reported by Bram Moolenaar).</li>

<li>implement <em>metaSendsEscape</em> resource, with
    corresponding control sequence and menu entry. Like
    <em>eightBitInput</em>, this causes xterm to send ESC prefixing
    the given key, but applies to all keys and is independent of
    the 8-bit/7-bit terminal setting. (requests by Alexander V
    Lukyanov and Marc Feeley).</li>

<li>correct potential indexing with negative subscript in
    udk_lookup(), (reported by Ian Collier
    &lt;Ian.Collier@comlab.ox.ac.uk&gt;).</li>

<li>modify configure script that sets TERMINFO_DIR to use
    ${prefix} rather than /usr if the --prefix option was specified
    (request by Zdenek Sekera &lt;zs@sgi.com&gt;).</li>

<li>modify checks for repeat-character control sequence to test
    the character class against xterm's state table, rather than
    the isprint() macro (patch by Alexander V Lukyanov).</li>

<li>change several functions to macros to improve speed</li>

<li>two corrections to simulation of bold font via
    overstriking:

<ul>
        <li>use clipping to avoid leaving trash at end of the text,
        and</li>

<li>add brackets so wide-character logic does not
        fall-through into the overstriking logic (reported by Marc
        Feeley &lt;feeley@IRO.UMontreal.CA&gt;)</li>
      </ul>
    </li>

<li>add several entries to termcap file to make it have the
    same set of aliases as the terminfo file.</li>

<li>scale the color values used for xterm-256color terminfo
    entry to 0..1000, as expected by ncurses.</li>

<li>change xterm-r6 terminfo definitions for F1-F4 to match
    program.</li>

<li>Add QNX/Neutrino support (Frank Guangxin Liu
    &lt;frank@ctcqnx4.ctc.cummins.com&gt;)</li>
  </ul>

<h1><a name="xterm_121" id="xterm_121">Patch #121 - 1999/11/14 -
  XFree86 3.9.16c</a></h1>

<ul>
    <li>change label on "Sun/PC Keyboard" popup menu entry to
    "VT220 Keyboard", since the checked state corresponds to VT220
    rather than Sun/PC.</li>

<li>add configure test CF_UTMP_UT_XSTATUS to handle the
    variants of utmp exit status (reports by Dave Ellement, Jeremie
    Petit, Tomas Vanhala).</li>

<li>amend treatment of ALT key (see <a href="#xterm_94">patch
    #94</a>) so that if ALT is used as a modifier in key
    translations, then no parameter will be sent in escape
    sequences for Sun/PC function keys (request by Dr Werner
    Fink).</li>

<li>modify default for OPT_I18N_SUPPORT to assume that
    <code>XtSetLanguageProc()</code> is available in X11R5.

<p>Caveat: <code>XtSetLanguageProc()</code> was added fairly
      late in the X11R5 patches, and some vendors shipped buggy
      versions of this function (request by Tomas Vanhala).</p>
    </li>

<li>correct configure macro CF_SYSV_UTMP to test-link with
    functions consistent with the header, e.g., getutent() for
    utmp.h and getutxent() for utmpx.h (reported by Greg
    Smith).</li>

<li>modify terminfo entry for <code>xterm-xfree86</code> to
    reflect modifiers for shift and control (from a patch by
    Alexander V Lukyanov).</li>

<li>modify terminfo entry for <code>xterm-sun</code> to match
    the function-key definitions in ncurses. The pageup/pagedown
    and related function keys correspond to the Sun keyboard, which
    does not necessarily correspond with X's notion of those
    keys.</li>

<li>modify treatment of XK_Delete keysym so it transmits
    parameterized VT220-style <code>&lt;ESC&gt;[3~</code> if
    modifiers (shift, control alt) are given (request by Alexander
    V Lukyanov).</li>

<li>corrected misspelled resource name in command-line option
    for HP function keys.</li>
  </ul>

<h1><a name="xterm_120" id="xterm_120">Patch #120 - 1999/10/28 -
  XFree86 3.9.16c</a></h1>

<ul>
    <li>refine the change to <code>SGR_Background()</code> in patch
    #119, by not flushing the pending scrolling operation if the
    background color is not actually changing. This combination
    occurs when using color-ls to display a long listing, since
    each line ends with an SGR0 which affects only the foreground
    color. The unnecessary flushing made it noticeably slower
    (reported by D Roland Walker &lt;walker@pobox.com&gt;).</li>

<li>remove obsolete documentation about modifiers which can be
    returned in mouse tracking mode, and modify logic to ignore
    modifiers other than the existing ones, e.g., NumLock (prompted
    by discussions with Christian Weisgerber and Brad Pepers
    &lt;brad@linuxcanada.com&gt;).</li>

<li>use free bit from obsolete shift-modifier coding of mouse
    tracking button events to encode buttons 4 and 5, e.g., for a
    wheel mouse (requests by Brad Pepers and Bram Moolenaar).</li>

<li>correct a place where the ptyInitialErase logic did not set
    the backarrowKey state, and modify it further to use tgetstr()
    rather than parse the termcap data returned from tgetent() so
    the ptyInitialErase logic will work when xterm is linked with a
    terminfo library (based on a patch by Dr Werner Fink
    &lt;werner@suse.de&gt;).</li>

<li>fix definition of HAVE_UTMP_UT_HOST for ISC configuration
    (patch by Michael Rohleder).</li>

<li>improve configure script's utmp tests (based on reports by
    Greg Smith for os390, and David Ellement for HPUX).</li>

<li>modify sinstall.sh to use uid=0 rather than 'root' to
    determine if the installer is privileged. This is needed on
    some systems since more than one account may be privileged
    (report by Greg Smith).</li>

<li>add an application resource, <code>messages</code> (and a
    corresponding -/+mesg option) which controls the initial
    permission on the terminal: if messages is set to true (the
    default), behavior is as without the patch; if it is set to
    false (as per -mesg), the terminal is opened in mode 0600, thus
    producing the effect of the <code>mesg n</code> command. This
    is useful for users who want to redirect all their messages to
    one particular xterm: it is more pleasant to do this with xterm
    resources than with explicit calls to the <code>mesg</code>
    program (patch, description by David Madore
    &lt;david.madore@ens.fr&gt;).</li>
  </ul>

<h1><a name="xterm_119" id="xterm_119">Patch #119 - 1999/10/16 -
  XFree86 3.9.16c</a></h1>

<ul>
    <li>add responses (DA and DSR) for DEC locator mode</li>

<li>add coding for ANSI color to DA response</li>

<li>implement UTF-8 translation for Media Copy (print)
    operations.</li>

<li>implement vt320 control sequences for Print Composed Main
    Display and for Print All Pages. The latter directs xterm to
    print the current screen as well as the scrollback buffer.</li>

<li>correct error in _GNU_SOURCE configure test, which left it
    always defined.</li>

<li>add more information, i.e., with strerror for some system
    calls in the main program which may fail due to insufficient
    permissions (prompted by a problem report for <code>-C</code>
    by Jeremie Petit &lt;Jeremie.Petit@digital.com&gt;).</li>

<li>add workaround for conflict between &lt;X11/Xpoll.h&gt; and
    &lt;sys/select.h&gt; on AIX 4.3 (Richard Griswold
    &lt;griswold@acm.org&gt;).</li>

<li>add configure script test to resolve conflict between
    between &lt;X11/Xpoll.h&gt; and &lt;sys/select.h&gt;</li>

<li>modify translation of UTF-8 sequences to reject "overly
    long" variations (patch by Markus Kuhn).</li>

<li>remove <code>utf8controls</code> resource, since Markus'
    change removes the corresponding logic.</li>

<li>correct a case where colors were not rendered properly.
    This happened when an application inserted several lines, then
    changed colors. If this was done all in one write, then there
    would be no intervening refresh, and the new color was applied
    to the pending scrolling operation which was awaiting the next
    refresh (reported by Stephane Chazelas
    &lt;Stephane_Chazelas@Raytheon.com&gt;).</li>
  </ul>

<h1><a name="xterm_118" id="xterm_118">Patch #118 - 1999/10/5 -
  XFree86 3.9.16b</a></h1>

<ul>
    <li>refine configure test for utmp versus utmpx, to build on
    HP-UX 10.x (reported by David Ellement).</li>

<li>move the configure check for <code>const</code> after the
    check for ANSI C compiler options, since those may be required
    to make it work properly on HP-UX.</li>

<li>add configure test for defining
    <code>_GNU_SOURCE</code></li>

<li>correction to <em>-hold</em> option, ensure that if data is
    already in the output buffer that it will be displayed before
    closing the PTY.</li>

<li>move the configure checks for setuid install of xterm into
    a script to avoid installing it setuid'd to a non-root user
    (reported by Adam Sulmicki &lt;adam@cfar.umd.edu&gt;).</li>

<li>correct configure script's check for termcap.h to avoid
    using ncurses' version of it on systems that have a working
    <code>tgetent()</code> function. This is needed to make
    <code>resize</code> work properly.</li>

<li>fix some typography in ctlseqs.ms description of DEC
    locator events (reported by Stephen P Wall).</li>
  </ul>

<h1><a name="xterm_117" id="xterm_117">Patch #117 - 1999/9/29 -
  XFree86 3.9.16b</a></h1>

<ul>
    <li>change order of tests in configure script for utmp and
    utmpx to test utmpx first, to compile on Solaris (reported by
    Leena Heino &lt;liinu@uta.fi&gt; and Patrik Hagglund
    &lt;patha@ida.liu.se&gt;).</li>

<li>add a configure test for utmp.ut_xtime, needed for SCO
    Openserver, and for lastlog, needed for Redhat 6.0, to refine
    the utmp/utmpx auto-configure.</li>

<li>remove a spurious comma in an #undef (reported by David
    Green &lt;greendjf@cvhp152.marconicomms.com&gt; and David
    Ellement &lt;ellement@sdd.hp.com&gt; both on HP-UX, whose
    compiler does care about syntax).</li>

<li>change ifdef's using __CYGWIN32__ to __CYGWIN__ (reported
    by Suhaib M. Siddiqi &lt;Ssiddiqi@InspirePharm.Com&gt;, who is
    told that the next Cygnus release will drop that symbol in
    their next release).</li>

<li>minor cleanup of ifdef's for makeColorPair (patch by
    Stephen P Wall).</li>

<li>work around problem observed in XFree86 3.3.5 (patch by
    Alexander V Lukyanov, Redhat #5419). From the problem report:

<blockquote>
        <p>xterm consumes cpu when selecting text with mouse
        (holding down left mouse button) and when a program working
        under the xterm outputs something to stdout.</p>

<p>Easy way to reproduce:<br>
        <code>while :; do echo aaa; sleep 1; done</code><br>
        (while this runs, select text and hold down left mouse
        button) watch cpu load.<br>
        release left mouse button - spinning stops.</p>
      </blockquote>
    </li>
  </ul>

<h1><a name="xterm_116" id="xterm_116">Patch #116 - 1999/9/25 -
  XFree86 3.9.16a</a></h1>

<ul>
    <li>modify warning if change-ownership of PTY fails; some
    configurations may not happen to have old-style pty's (reported
    by Bob Maynard).</li>

<li>improve check in configure script for group ownership of
    installed xterm; some platforms use the -g option of ls to
    toggle group off rather than on (reported by Greg Smith).</li>

<li>minor improvement to toolbar geometry, to make it not
    resizable. This still is not satisfactory (but is usable) since
    the toolbar overlaps the xterm widget if the window is resized
    to make it smaller. It appears that some work is needed for the
    xterm widget's geometry management to make it function
    properly.</li>

<li>implement configure script tests for utmp, tty group.</li>

<li>implement <em>-hold</em> option, allowing users to retain
    the window after a shell has exited (this is recently an FAQ,
    but prompted by a comment by Joachim Plaettner-Hochwarth
    &lt;plaettner@aem.umn.edu&gt; in comp.unix.programmer, that the
    IRIX winterm provides this option).</li>

<li>add support for DEC Locator control sequences for xterm
    (integrated patch by Stephen P Wall):

<pre>
                DECEFR, "Enable Filter Rectangle"
                DECELR, "Enable Locator Reports"
                DECSLE, "Select Locator Events"
                DECRQLP, "Request Locator Position"
</pre>

<p>This allows the xterm mouse to be used with applications
      that use the DEC Locator sequences, such as VAX Tpu, or SMG$
      based applications.</p>
    </li>

<li>improve print action (patch by Matthias Baake). From his
    notes,

<ul>
        <li>Bug 1<br>
        Underlined text is preceded by ESC&nbsp;[0;2m . This should
        be ESC&nbsp;[0;4m&nbsp;, ESC&nbsp;[2m doesn't seem to have
        any effect. (print.c/send_SGR)</li>

<li>Bug 2<br>
        The check for the last non-empty column (while (last &gt;
        0) ... in print.c/printLine) omits the rightmost column of
        the screen, the loop must start with last =
        screen-&gt;max_col+1 instead of last =
        screen-&gt;max_col.</li>

<li>Bug 3<br>
        Any attributes of the first character (and of all
        immediately following characters with the same attributes)
        are ignored. The variable attr (print.c/printLine) should
        be initialized with 0, not with *a &amp; SGR_MASK.</li>
      </ul>
    </li>
  </ul>

<h1><a name="xterm_115" id="xterm_115">Patch #115 - 1999/9/18 -
  XFree86 3.9.16a</a></h1>

<ul>
    <li>integrated changes by Stephen P Wall to implement an
    88-color model for systems where 256-colors cannot be
    allocated.</li>

<li>when 256-color configuration is compiled, colored bold and
    underlining is not available; ifdef'd to avoid possible odd
    effects in this case (reported by Stephen P Wall).</li>

<li>add resource <em>cacheDoublesize</em>, to limit the caching
    of font information for double-sized characters. This addresses
    a problem reported by Aryeh Koenigsberg for X terminals with
    limited font memory.</li>

<li>modify treatment of line-drawing characters in UTF-8 mode
    so that the Unicode values are used rather than the C0 codes
    for storing the translated characters (request by Markus
    Kuhn).</li>
  </ul>

<h1><a name="xterm_114" id="xterm_114">Patch #114 - 1999/9/15 -
  XFree86 3.9.16</a></h1>

<ul>
    <li>add configure script checks for Athena headers and
    libraries under /usr/contrib to work on HPUX (reported by
    several people: David Nixon &lt;djn@csc.liv.ac.uk&gt; Aryeh
    Koenigsberg &lt;aryeh.koenigsberg@telrad.co.il&gt; Johannes
    M&auml;hner &lt;johanm@camline.com&gt; Andrew Gaylard
    &lt;andrew.gaylard@bsw.co.za&gt;).</li>

<li>add check to configure script if xterm is installed setgid
    rather than setuid, since wtmp and utmp may be installed with
    group-writable permissions other than root (based on Debian bug
    report #7112 by Bo Branten &lt;bosse@ing.umu.se&gt;).</li>

<li>rewrote logic that removes data from termcap entry, e.g.,
    for titeInhibit, to make it less likely to remove the wrong
    data.</li>

<li>correct logic which checks for missing characters used for
    line drawing. The 0 character was tested unnecessarily, leading
    to some inefficiency when rendering.</li>

<li>change termcap capability which is used as input or output
    of ptyInitialErase logic from <em>kD</em> to <em>kb</em>.
    Christian Weisgerber &lt;naddy@mips.rhein-neckar.de&gt; pointed
    out in effect that <em>kD</em> (in terminfo <em>kdch1</em>)
    should correspond to the control sequence for <em>dch1</em>,
    which deletes from the current position toward the right.</li>

<li>check for failure to change ownership of the PTY device and
    warn when xterm is running setuid'd to root. This was reported
    to happen on the FreeBSD/NetBSD/OpenBSD systems as a result of
    the chflags() call.</li>

<li>add xterm-noapp terminfo entry to illustate a nominally
    bash-compatible terminal description.</li>
  </ul>

<h1><a name="xterm_113" id="xterm_113">Patch #113 - 1999/8/15 -
  XFree86 3.9.15b</a></h1>

<p>Several fixes. The main one is a first draft of pulldown
  menus. It's not complete (I have some minor/annoying geometry
  problems to correct), but is usable. Once it's complete I plan to
  add a menu to support additional selections that won't fit on the
  current popup menus. Also, this fits into my longterm plan to
  allow configuring with Motif libraries.</p>

<ul>
    <li>correct error in input conversion for NRC mode (reported by
    Stefan Traby &lt;stefan@sime.com&gt;).</li>

<li>fix initialization of num_lock data in Misc struct (since
    those fields of the reference widget aren't initialized), and
    add logic to deal with XVision whose NumLock key does not
    transmit but does alter keypad state.</li>

<li>correct a missing return-value in get_pty(), for SCO</li>

<li>add E2A fix for backspace (patch by Greg Smith), i.e.,<br>
    #define VAL_INITIAL_ERASE A2E(127)</li>

<li>correct foreground color within cursor outline when the
    window is unfocused (reported by Stephane Chazelas).</li>

<li>corrected position of scrollbar set in ResizeScrollBar(),
    which left it positioned incorrectly if the right scrollbar
    were enabled from the popup menu but was not initially enabled.

<p>I have noticed some additional problems with
      right-scrollbar on X11R5 which I will correct later.</p>
    </li>

<li>integrate changes by Jean-Claude Michot for QNX from
    XFree86 3.3.4c</li>

<li>add resources menuBar/MenuBar, menuHeight/MenuHeight for
    later use in toolbar geometry.</li>

<li>add configure option --enable-toolbar</li>

<li>add missing definition to make ziconbeep logic not
    compile-in when configure script disables it.</li>

<li>add configure-check for input-method support in X
    libraries</li>
  </ul>

<h1><a name="xterm_112" id="xterm_112">Patch #112 - 1999/7/17 -
  XFree86 3.9Pw</a></h1>

<ul>
    <li>add null-pointer check to FlushLog(), fixes a core dump
    when both -l and -lf options are used when xterm is configured
    with wide-character support.</li>

<li>remove "ISO" case for SD, which was due to a typographical
    error in ECMA-48 (reported by Paul Williams
    &lt;paul@celigne.co.uk&gt; for vttest).</li>

<li>add "FILES" section to manpage.</li>

<li>generate header file to initialize default resources for
    colors 16-255.</li>

<li>fixes for os390 (Greg Smith):

<ul>
        <li>add README.os390</li>

<li>use the pty_search() function to find an available
        pty/tty pair.</li>

<li>move E2A() call out of getXtermCell() to SaveText()
        function so it will be available in all
        configurations.</li>
      </ul>
    </li>

<li>patches by Todd Larason:

<ul>
        <li>enable SGR 48 5 in ISO color mode, not just 256 color
        mode</li>

<li>change configure's --disable-256-color option to
        --enable-256-color, to match its effect</li>

<li>fix OSC 4 xx ? (report ansi color) to report a string
        which can actually be used to set the color back</li>

<li>fix OSC 4 xx yy (change ansi color) to not allow
        setting colors &gt; 15 in 16 color mode</li>

<li>simplify the COLOR_ settings a bit in ptyx.h, along
        with setting NUM_ANSI_COLORS needed for #1 and #4
        above</li>

<li>correct string-terminator code passed for reference to
        OSC responses; when in 7-bit mode, only the final byte of
        ST was seen.</li>

<li>Allow multiple color #;name pairs in OSC 4, and
        document changes to match.</li>
      </ul>
    </li>
  </ul>

<h1><a name="xterm_111" id="xterm_111">Patch #111 - 1999/7/10 -
  XFree86 3.9Pw</a></h1>

<ul>
    <li>add control sequences for specifying the RGB value of the
    ANSI colors, and for configuring with 256 colors (patch by Todd
    Larason &lt;jtl@molehill.org&gt;). I made the default
    configuration to 16-colors, because xterm uses the default
    color map (which has only 256 colors).</li>

<li>correct an error in DCS $ q m reporting for colors 8-15
    (Todd Larason).</li>

<li>add test/demo script for double size characters. Used this
    to test/correct display of double size characters that should
    wrap, underlined double size characters.</li>

<li>increased cache size for double size fonts to 8, to allow
    for both normal and bold fonts (discussion with Aryeh
    Koenigsberg &lt;aryeh.koenigsberg@telrad.co.il&gt;).</li>

<li>add fixes for port to OS390 aka MVS (integrated patch from
    Greg Smith &lt;rys@epaibm.rtpnc.epa.gov&gt;). OS390 uses EBCDIC
    rather than ASCII.</li>

<li>correct an off-by-one in binary search limits in
    keysym2ucs.c (Markus Kuhn).</li>

<li>implement logging for UTF-8 mode. The output is written in
    UTF-8 form.</li>

<h1><a name="xterm_110" id="xterm_110">Patch #110 - 1999/6/29 -
  XFree86 3.9Pu</a></h1>

<ul>
    <li>If colorMode is enabled by default, compile-in default
    resources to match the colors listed in XTerm-col.ad (this
    should fix a longstanding FAQ).</li>

<li>added new OSC&nbsp;3&nbsp;;&nbsp;PROPNAME=VALUE&nbsp;ST
    escape sequence to set an arbitrary X property on the top level
    xterm X11 window. Omit "=VALUE" to delete the X property (patch
    by Greg Badros &lt;gjb@cs.washington.edu&gt;).</li>

<li>change internal flag used for <em>utf8controls</em>
    resource so we allow 31-bit range of characters (suggested by
    Thomas Wolff).</li>

<li>add check for 16-bit characters in OSC strings, change them
    to '?' (reported by Thomas Wolff).</li>

<li>modify logic of same_font_name() to avoid trying to
    interpret both parameters as wildcard patterns. That does not
    (cannot) work, and in some instances the font server will
    return unresolved wildcards for the normal or bold fontnames,
    making them match inadvertently, triggering the fallback
    overstrike logic (reported by Tim Adye).</li>
  </ul>

<h1><a name="xterm_109" id="xterm_109">Patch #109 - 1999/6/23 -

<ul>
    <li>correct range-check from patch #108, which resulted in not
    being able to select from the scrollback buffer (reported by
    Tim Adye &lt;T.J.Adye@rl.ac.uk&gt;)</li>

<li>correct "no available ptys" problem with Cygwin B20.1
    (patch by Tim Adye).</li>

<li>modified install-ti rule in Makefile.in to allow override
    of the terminfo directory when doing a "make install", i.e., by
    assigning to TERMINFO_DIR (request by Zdenek Sekera
    &lt;zs@sgi.com&gt;).</li>

<li>added install-full rule to Makefile.in</li>

<li>resync mkdirs.sh and install.sh scripts against current
    autoconf</li>

<li>implement $(DESTDIR) in Makefile.in, making it simple to
    install xterm and associated files into a directory just for
    packaging a binary release (suggested by CaT
    &lt;cat@zip.com.au&gt;).</li>

<li>change IChar type to unsigned, rather than unsigned short,
    making room for a flag to keep with 16-bit characters to
    prevent them from being interpreted as C0 or C1 controls
    (reported by Thomas Wolff).</li>

<li>correct a typo from patch #107, incorrect array name, in
    the filterUTF8 function (patch by Bruno Haible
    &lt;haible@ilog.fr&gt;)</li>

<li>add <em>utf8controls</em> resource to specify whether xterm
    should interpret 16-bit characters unpacked from UTF-8 form as
    control characters if they happen to fall into that range. This
    behavior is left unspecified by the Unicode standard (request
    by Thomas Wolff).</li>

<li>modify handling of OSC to recover if application sends
    16-bit characters with codes above 255. We cannot display them
    as is, but translate out-of-range characters to a '?' (reported
    by Thomas Wolff).</li>

<ul>
    <li>add a range-check to LastTextCol(), to guard against

  XFree86 3.9Pq</a></h1>

<ul>
    <li>Two changes from Stephen P Wall. From his description:

<blockquote>
        <p>The first change is simple - I added ESC[3J to erase the
        stored lines above the screen. That's what the changes to
        util.c and ctlseqs.ms are.</p>

<p>The second change is to get the blinking cursor working.
        I took out the cursorBlinkTime resource, and put in
        cursorBlink (Boolean), cursorOnTime (time cursor is on in
        msecs) and cursorOffTime, and added a cursorblink item to
        the vtMenu to enable/disable it.</p>
      </blockquote>
    </li>

<li>improve selection (integrated patch by Juliusz Chroboczek).
    From his description:

<blockquote>
        <p>With this patch, selection conversion works
        properly:</p>

<pre>
        ISO 8859-1 xterm -&gt; ISO 8859-1 xterm (transferred as STRING);
        ISO 8859-1 xterm -&gt; UTF-8 xterm (transferred as STRING);
        UTF-8 xterm -&gt; ISO 8859-1 xterm (transferred as STRING);
        UTF-8 xterm -&gt; UTF-8 xterm (transferred as UTF-8).
</pre>

<p>It will not work properly if one xterm is in, say, ISO
        8859-2. Actually, for this case xterm breaks the ICCCM
        routinely (sending ISO 8859-2 data as STRING), so I
        wouldn't worry too much about it. I have not changed the
        behaviour in eight-bit mode in any way.</p>

<ul>
    <li>implement new resource <em>trimSelection</em>, which allows

    not affect the highlighting. (reported by several people using
    <em>mutt</em>, including Hans Morten Kind &lt;edphk@uib.no&gt;,

  XFree86 3.9Pn</a></h1>

<p>This is a resync patch against XFree86 3.9Pn, reflecting
  changes which were submitted by Branden Robinson, who worked with
  Wichert Akkerman &lt;wichert@cs.leidenuniv.nl&gt; to set up
  ifdef's to handle GNU libc 2.1, and use getpt() which lets xterm
  avoid having to know the actual PTY name.</p>

<p>I have also added a few fixes for signed/unsigned mismatches,
  and corrected a problem in the configure script (the UTF-8 code
  was always configured since the Imakefile defines this).</p>

  XFree86 3.9Pm</a></h1>

<ul>
    <li>correct selection logic: I omitted an offset that accounts
    for the distance into the scrollback buffer when rewriting this
    for patch #101. Also fixed a similar problem for selecting
    double size characters from the scrollback buffer (first was
    reported by D Roland Walker &lt;walker@pobox.com&gt;).</li>

<li>improved support for Unix98 PTY's, using patch in Debian
    bug report #35650, by J.H.M. Dassen
    &lt;jdassen@wi.leidenuniv.nl&gt;. From the patch description:

<blockquote>
        <ul>
          <li>No longer links xterm against libutil on a glibc2.1
          system. libutil is a compatibility library and should
          only be used when necessary. Rather than having get_pty()
          use openpty() from this compatibility library, use the
          real UNIX98 pty support in get_pty() (open()ing the
          master pty, through getpt() if available (glibc
          extension)). Use openpty() only under glibc2.0.</li>

<li>GNU libc2 is not Linux-specific; already it runs on
          the Hurd. It provides the UNIX98 pty functions (plus the
          getpt() extension), regardless of the underlying OS.
          Changed two constructs to look for GNU libc2 only, not
          GNU libc2 on Linux.</li>
        </ul>
      </blockquote>
    </li>

<li>improve font configuration, by checking if the user's

    Brand).</li>

<li>modify print.c to move include of stdio.h after the

<li>eliminate conflicting definitions for USE_TERMINFO in
    resize.c (reported by Jeremy Buhler).</li>

<li>change openpty call to pass NULL rather than ttydev

    the corresponding data, and may not really be long enough
    (reported by Andreas Jaeger)</li>

<li>update description in xterm manpage for character class
    table, which said it handles only 7-bit codes.</li>

<li>correct a typo in ScrnDeleteChar() which made it not clear
    the high byte of wide-character data.</li>

<li>add logic to convert selection to UTF-8 form when

    settings.</li>

<li>modify the UTF-8 decoder so that all possible illegal UTF-8
    sequences are properly represented by U+FFFD. This should be
    very helpful for developers of code that output UTF-8 strings
    for debugging. See the file utf-8-test.txt in

    (reported by Vikas Agnihotri).</li>

<li>remove duplicate definition of USE_USG_PTYS (reported by
    Jeremy Buhler).</li>

<li>change termcap <em>kD</em> and terminfo <em>kdch1</em> to a
    DEL (\177). I overlooked this when separating the styles of
    keyboard with the <em>sunKeyboard</em> resources in patch #94,
    so that it normally matches the value of the stty erase
    character:

<ul>
        <li>Reported by Jae Gangemi
        &lt;jgangemi@ccf.rutgers.edu&gt;, this caused emacs to not
        process the DEL properly, combining it with succeeding
        characters.</li>

<li>This does not appear to be related to a problem which I
        have found with <em>screen</em>, which translates the stty
        erase into the termcap <em>kD</em> or terminfo
        <em>kdch1</em> value (depending on how it is linked) if the
        $TERMCAP variable is set when <em>screen</em> is
        invoked.</li>
      </ul>
    </li>

<li>add command-line options for enabling UTF-8 mode: -u8 and
    +u8. The more obvious -utf8 and +utf8 would conflict with
    xterm's -ut and +ut (utmp) options. The UTF-8 changes were
    requested by Markus Kuhn &lt;Markus.Kuhn@cl.cam.ac.uk&gt;. This
    patch does not complete UTF-8 implementation, but makes it
    usable, i.e., display and refresh work, and I am able to
    display the test cases which Markus provides. More work is
    needed to complete this feature:

<ul>
        <li>the control sequences for switching in/out of UTF-8
        mode are partly implemented (don't use them). Similarly,
        the switching between vt100 and tek4014 emulations when
        UTF-8 mode is enabled will not work properly.

<p>You must use the -u8 command line option to use this
          feature, as well as compile with the OPT_WIDE_CHARS
          definition.</p>
        </li>

<li>cut/paste only copies 8-bit characters.</li>

<li>logging is disabled in the wide-character

<h1><a name="xterm_93" id="xterm_93">Patch #93 - 1999/3/14 -
  XFree86 3.9Pd</a></h1>

<p>Here are several fixes and minor enhancements. The chief ones
  are the fixes for NumLock mode and reverse video, since we had
  become used to working around the problems.</p>

<ul>
    <li>remove kfnd/kll/kslt strings from terminfo, because curses
    applications do not necessarily return khome/kend pairs
    (reported by Vikas Agnihotri).</li>

<li>implement NumLock resource which overrides the keyboard
    tables for the special case of keypad keys. This is a problem
    introduced in xterm by X11R6 changes, i.e., an ambiguity which
    in effect discarded vt100 keypad support.</li>

<li>modify Sun/PC keyboard mode to extend this (emulation of
    DEC vt100 keypad) to the remainder of the numeric keypad. Now,
    the default operating mode of xterm uses the keyboard tables
    as-is (except if the NumLock mode overrides), but provides good
    vt100 keypad compatibility if the Sun/PC keyboard menu item is
    checked.</li>

<li>separate command-line settings for reverse video from that

<h1><a name="xterm_92" id="xterm_92">Patch #92 - 1999/2/5 -
  XFree86 3.9Nz</a></h1>

<ul>
    <li>increase buffer size for tgetent (i.e., termcap) to 1500.
    This fixes a problem where <em>screen</em> is built using
    ncurses or GNU termcap and <em>xterm</em> is built using the
    standard termcap interface. The former does not limit the
    termcap size, while the latter is assumed to be no longer than
    1023 characters. The <em>screen</em> program's termcap entry is
    about 1200 characters long.</li>

<li>change update_menu_item() to a function, to simplify
    debugging. This also reduces the executable by 4Kb.</li>

<li>add control sequences for DECSET 30, 1010, 1011 like rxvt
    (enable or disable some features that were only settable via
    resources or command line arguments).</li>

<li>add control sequence for DECSET 35, which enables/disables
    the shifted keypad functions.</li>

<li>add support for switching font sizes, by stepping through
    the font menu using shifted keypad plus and minus.</li>

<li>correct missing initialization of tekInhibit and tekSmall
    resources.</li>

<li>correct ifdef's in charproc.c for XtNgeometry and
    XtCGeometry (reported by Bram Moolenaar).</li>

<h1><a name="xterm_90" id="xterm_90">Patch #90 - 1998/12/13 -
  XFree86 3.9Nq</a></h1>

<p>This implements several small fixes and enhancements. The
  chief one implements fallback support for line drawing characters
  with fonts that do not include those characters. But I
  implemented that last.</p>

<ul>
    <li>If any of the glyphs in positions 0-31 (used by xterm to
    implement the VT100 alternate character set) are zero-sized
    (i.e., missing), xterm will reserve a normal space for the
    glyph when drawing. I implemented a simple stroke-drawing
    function to draw the line-drawing characters and a couple of
    the other (simpler) characters such as diamond. (This was
    suggested by Vikas Agnihotri).</li>

<li>Modify the computation of doublesize characters to work
    around font servers which shift the scaled characters up/down
    or do not give the correct width.</li>

<li>Add popup menu item and corresponding resource settings to
    disable the font-scaling logic for doublesize characters to
    work around (older) font servers which simply do not draw the
    fonts scaled to the size that they said they would. I see this
    problem on a SunOS system running X11R5; the X11R6 servers seem
    well behaved.</li>

<li>Implement new escape sequence, private mode 1049, which
    combines the switch to/from alternate screen mode with screen
    clearing and cursor save/restore. Unlike the existing escape
    sequence, this clears the alternate screen when switching to it
    rather than when switching to the normal screen, thus retaining
    the alternate screen contents for select/paste operations.

<p>When I implemented the popup menu entry to toggle between
      the normal and alternate screens, I considered only pasting
      from the normal screen to the alternate; this improvement
      allows either direction.</p>
    </li>

<li>Changed the termcap and terminfo for xterm-xfree86 and
    xterm-8bit to use the new 1049 private mode.</li>

<li>Modify the logic which switches between normal and
    alternate screens so that the save/restore cursor operations
    apply only to the current screen. That means that applications
    which use the terminfo smcur/rmcur or termcap ti/te
    capabilities will restore the cursor to the original position
    on the normal screen rather than to the most recent place where
    a save-cursor operation was performed.

<p>I note that a real VT100 terminal would not behave in this
      way, but it is a moot point since the VT100 does not
      implement alternate screen, and therefore the save/restore
      cursor sequence would not be used in this context. I reviewed
      the logic which switches between normal and alternate screens
      based on some recent newsgroup postings as well as a proposed
      patch in the Debian group which attempts to do this (the
      patch has a bug, however, so I did not use it).</p>
    </li>

<li>Add popup menu entry for toggling the titeInhibit
    resource.</li>

<li>Add new resource answerbackString, which overrides the
    default "xterm" returned by xterm when responding to an ENQ
    (control/E) character (request by Rajesh Vaidheeswarran
    &lt;rv@fore.com&gt;).</li>

<li>Add new resource keyboardDialect for setting the NRC
    display character set (request by Tomas Vanhala, who notes that
    I should add logic to translate the keyboard as well).</li>

<li>Add new command-line option and corresponding resources for
    making xterm generate escape sequences compatible with HP
    terminals. Like the existing Sun escape sequences, this is
    available as a popup menu item. It is enabled by the configure
    script with the option --enable-hp-fkeys (requested by Toni
    Mueller &lt;sales@oeko.net&gt;).</li>

<li>Add configure script option --disable-boxchars to disable
    the fallback support for line drawing characters.</li>

<li>Fix ifdef's for configure script --disable-ansi-color, and
    reviewed all configure options to ensure that all can be
    enabled/disabled appropriately.</li>

<li>Update config.guess and config.sub, from Lynx.</li>
  </ul>

<h1><a name="xterm_89" id="xterm_89">Patch #89 - 1998/11/20 -
  XFree86 3.9Nm</a></h1>

<p>This patch completes the implementation of double-sized
  character support for the VT100 emulation, and fixes a few minor
  bugs:</p>

<ul>
    <li>corrected the cursor position in HideCursor, which did not
    multiply the column by two when in doublesize mode. This bug,
    which did not appear in normal use, dates back to my original
    <a href="#xterm_44">changes</a> to partly implement
    double-sized characters. I noticed it when cat'ing a typescript
    from vttest's double-sized character test.</li>

<li>ensure that the current line is repainted when switching
    between single and double width characters.</li>

<li>reduce the number of bits used for double-sized character
    coding from 3 to 2, to make more room for soft-font codes.</li>

<li>copy newer ifdef's from the XFree86 3.3.3 release's main.c,
    which address details of glibc and powerpc.</li>

<li>moved definition of DECL_ERRNO in xterm.h to match XFree86
    3.3.3</li>

<li>modify <em>resize</em> to remove the ifdef on SVr4 that
    suppressed printing the script for $LINES and $COLUMNS.
    Solaris' resize utility does this; suppressing the behavior is
    unnecessary.</li>
  </ul>

<p>I tested the double-sized characters using vttest and the
  xfsft patch. These fonts worked reasonably well:</p>

<pre>
        -bitstream-courier-medium-r-normal--0-0-0-0-m-0-iso8859-1
        9x15
</pre>

<p>The iso8859 font does not include box characters, of course,
  but looks good.</p>

<h1><a name="xterm_88" id="xterm_88">Patch #88 - 1998/10/31 -
  XFree86 3.9Nk and 3.3.2h</a></h1>

<p>This refines my #85 patch by checking for a case where the
  font server returns a bold font that does not quite correspond to
  the normal font. When I asked for a bold version of the 6x12
  font, the font server returned a near equivalent where the ascent
  and descent values did not match, causing xterm to leave lines
  across the display. This patch makes xterm reject that type of
  mismatch, falling back to the old font behavior.</p>

<h1><a name="xterm_87" id="xterm_87">Patch #87 - 1998/10/21 -
  XFree86 3.9Nj and 3.3.2f</a></h1>

<p>This corrects a problem reported by Stefan Dalibor. My table
  entries for the <em>printerExtent</em> and
  <em>printerFormFeed</em> resources used the wrong types for
  sizeof, causing the printer to not work properly on some
  platforms because the <em>printAttributes</em> resource was
  overwritten (e.g., Digital Unix with DEC Alpha).</p>

<p>I reviewed all of the resource table entries and fixed a
  potential problem with <em>resizeGravity</em>, which was typed as
  <em>int</em> rather than <em>XtGravity</em>.</p>

  XFree86 3.9Nj and 3.3.2e</a></h1>

<p>A small fix: when switching to/from the continuous mouse
  reporting mode, the event mask was incorrect if xterm was built
  under X11R5 because the original data was saved under an ifdef
  for active-icon.</p>

<h1><a name="xterm_85" id="xterm_85">Patch #85 - 1998/10/12 -
  XFree86 3.9Nj and 3.3.2e</a></h1>

<p>Some cleanup (I noticed the pixel droppings a few months ago
  after getting a new 17" monitor):</p>

<ul>
    <li>split-out the functions that load/reload fonts for xterm as
    new file fontutils.c to extend them to support automatic
    loading of bold font corresponding to the normal font. Adapted
    logic from EMU 1.3 for this purpose. This fixes most
    occurrences of pixel droppings from bold characters.</li>

<li>modified by renaming variables and adding casts to permit
    compile with g++.</li>

<li>modify headers so they can all be compiled without order
    dependencies, and use bracketed rather than quoting includes to
    allow compile from separate directory.</li>

<li>renamed xtermm terminfo entry to xterm-mono, to avoid
    conflict with Solaris entry now in ncurses.</li>
  </ul>

<h1><a name="xterm_84" id="xterm_84">Patch #84 - 1998/10/9 -
  XFree86 3.9Ni and 3.3.2e</a></h1>

<p>Several small fixes and enhancements, including a patch from
  Bjorn Helgaas:</p>

<ul>
    <li>correct initialization of TERMCAP environment variable,
    which was frequently set to garbage on non-Linux systems
    because "termcap" and "newtc" contained random data from the
    stack.</li>

<li>remove the LINEWRAPPED attribute from lines as they are
    cleared. Previously, the attribute was set but never
    cleared.</li>

<li>make word and line selections work even when lines are
    wrapped by xterm. Previously, selections were limited to one
    screen line.</li>
  </ul>

<ul>
    <li>modify logic for line-wrapping to reset the associated flag
    if the application deletes a character. This fixes a problem
    reported by Bjorn Helgaas where word/line selection would still
    wrap even after deleting characters from the first line.</li>

<li>add kll/kH capabilities to xterm-xfree86 entries in termcap
    and terminfo (request by Michael Schroeder).</li>

<li>shorten descriptions in termcap to make resolved entries
    all shorter than 1023 character limit.</li>

<li>use DECSTR control sequence to shorten initialization and
    reset strings in xterm-xfree86 termcap and terminfo.</li>

<li>use rmul/smul and rmir/smir in xterm-r5 terminfo to match
    termcap.</li>

<li>correct typos in initialization and reset strings in
    xterm-r5 termcap and terminfo.</li>

<li>disable special translations of key symbols (the backarrow
    key, the editing keypad and the keypad "+") when a modifier
    other than shift, control or numlock is used. This makes xterm
    handle the meta key as expected by people using emacs (reported
    by Pete Harlan &lt;harlan@pointofchoice.com&gt; in
    linux.debian.user newsgroup).</li>

<ul>
    <li>use X_EXTRA_LIBS in standalone Makefile.in (patch by Tomas

<li>determine the server's default foreground/background Pixel

    what the numeric keypad is supposed to do (reported by Ron
    Johnson, Jr. &lt;ronjohn@communique.net&gt;).</li>

<li>modify logic for editing keypad to work more like VT220:
    don't pass those codes in VT100-mode unless oldXtermFKeys mode
    is set.</li>

<li>correct an interaction with the editing-keypad logic that

<h1><a name="xterm_78" id="xterm_78">Patch #78 - 1998/6/3 -
  XFree86 3.9Ah and 3.3.2</a></h1>

<p>Again, most of the bulk of this patch is for ANSI conversion.
  I used the IRIX compiler's -wlint option to find the remaining
  functions that use K&amp;R syntax (since gcc does not do this
  properly). Also, I changed the logic in the print code slightly
  to close unwanted files before opening a pipe to the printer.
  This may help in some configurations where the line printer hangs
  until xterm closes the pipe.</p>

<h1><a name="xterm_77" id="xterm_77">Patch #77 - 1998/5/26 -
  XFree86 3.9Ah and 3.3.2</a></h1>

<p>Most of the bulk of this patch is to convert the extended C
  (K&amp;R functions with prototypes) to ANSI. I verified that on
  Linux by comparing object files, to ensure that I did not, for
  example, interchange parameters in the function declarations.</p>

<p>The rest of the patch fixes several minor bugs, and adds a few
  features:</p>

<ul>
    <li>back-out my use of ncurses "captoinfo -f" option
    (if/then/else/endif) formatting, since ncurses did not
    correctly filter embedded newlines in terminfo capability
    strings until _after_ ncurses 4.1, thus corrupting
    setf/setb/sgr strings (reported by Darren Hiebert and
    others).</li>

<li>document SGR 8, 28 (invisible/visible), add corresponding
    capabilities to terminfo description.

<p>I would also add the 'prot protected capability, but the
      control sequences for that would not be recognized or
      properly ignored by the older xterm programs.</p>
    </li>

<li>modify ChangeGroup to not suppress a null-resource, but
    treat it as an empty string (recommended by Stefan
    Dalibor).</li>

<li>add printerAutoClose resource to control whether printer is
    closed when going offline. More than one person reports
    problems (on Solaris 2.6 and Digital Unix 4.0) getting the
    printer to proceed unless xterm exits; I think that it is a
    problem flushing the pipe. Closing it ought to flush it.</li>

<li>adapt TOG fix-3 to in HandleKeymapChange and VTInitI18N
    (but adapt XtStackAlloc/XtStackFree for clarity, as well as
    fixing memory leak).</li>

<li>change calls on FillCurBackground to ClearCurBackground, in
    effect using XClearArea rather than XFillRectangle when
    clearing as a side-effect of scrolling and insertion (patch by
    Alexander V Lukyanov)</li>

<li>correct some places where insert/delete did not _move_ the
    color attributes, using memmove (patch by Alexander V Lukyanov
    &lt;lav@long.yar.ru&gt;)</li>

<li>add ifdef's for __CYGWIN32__, for port to cygnus version
    B19.1 (patch by Andrew Sumner
    &lt;andrew_sumner@hotmail.com&gt;).</li>

<li>remove #define for hpux that turned on USE_SYSV_ENVVARS,
    since this causes some applications (such as 'less') to get
    incorrect $LINES and $COLUMNS values (reported by Clint
    Olsen).</li>

<li>modify behavior for HP-UX, to set the "reserved" process
    group controls to _POSIX_VDISABLE so the TIOCSLTC ioctl does
    not produce an error (patch by Ben Yoshino
    &lt;ben@wiliki.eng.hawaii.edu&gt;).</li>

<li>correct length of underlining, reducing it by one pixel to
    avoid leaving a dot when the application does not clear the
    whole screen I noticed this only recently myself (and other
    people as well); it depends on the font chosen. A 6x10 font
    shows it, but the other fonts from XTerm.ad do not. I also see
    a similar problem with the emulation of bold fonts. (patch by
    Sergei Laskavy &lt;Laskavy@cs.msu.su&gt;).</li>

<li>add include for Xos.h to xterm.h, to ensure proper
    definitions (reported by Holger Veit).</li>

    "--with-own-terminfo-dir", which causes xterm to pass a
    predefined value of $TERMINFO to the application. Also use this
    value in install rule "make install-ti", for the standalone
    configure script. (patch &amp; feedback from Tor Lillqvist
    &lt;tml@hemuli.tte.vtt.fi&gt;)</li>

<li>change ifdef's for "hpux" to "__hpux" (patch by Tor
    Lillqvist). The imake configuration uses the former, but the
    latter is predefined by HP's compilers.</li>

<li>define USE_SYSV_ENVVARS for HP-UX, curses does not use
    $TERMCAP (patch by Tor Lillqvist).</li>

<li>on HP-UX, use the /dev/ptym/clone device to allocate PTY's.
    Works both on HP-UX 9 and 10. (patch by Tor Lillqvist).</li>

<li>modify configure script to obtain the $(EXTRA_LOADFLAGS)
    value from imake, needed for compiling under DEC OSF/1
    (reported by Stefan Dalibor)</li>

<li>modify print-window action so that the printer is closed
    after printing a window, unless the printer was already opened
    (i.e., by an application running in the window). This makes the
    printing complete without having to exit xterm, since not all
    systems treat fflush through a pipe very well (reported by
    Stefan Dalibor)</li>

<li>modify printing code so that the ^M's are not printed if
    the printAttribute resource is set to zero (request by Stefan
    Dalibor).</li>

<li>correct typo in xterm.man, for the default value of
    printAttribute (reported by Stefan Dalibor).</li>

<li>correct printing code so that the alternate character set
    is printed, like other attributes, with escape sequences.</li>

<li>correct termcap description, removing spurious 'm'
    character from the 'op' capability (reported by Greg Woods
    &lt;woods@weird.com&gt;).</li>

<li>correct trace code so that the initial timestamp is
    set.</li>

<li>correct/modify utmp data for the Linux glibc 2
    configuration, so that the ut_line member is set before using
    it to update wtmp (patch by Bill Nottingham
    &lt;wen1@cec.wustl.edu&gt;).</li>

<h1><a name="xterm_74" id="xterm_74">Patch #74 - 1998/4/27 -
  XFree86 3.9Ag and 3.3.2</a></h1>

<p>This corrects a couple of recent bugs and adds a new
  resource:</p>

<ul>
    <li>modify definition of TRACE_CHILD so that it does not
    conflict with ifdef's for USE_USG_PTYS in main.c (reported by
    Vikas Agnihotri &lt;VikasA@att.com&gt; and Stefan
    Dalibor).</li>

<li>correct ownership of file (actually pipe) written by the
    print controls. When undoing the setuid changes in patch #69, I
    overlooked this. Now xterm forks a process which resets setuid
    and routes the printer data as the real user.</li>

<li>add a new resource, "printAttributes", which controls
    whether color attributes (or any attributes) are sent to the
    printer.</li>
  </ul>

<h1><a name="xterm_73" id="xterm_73">Patch #73 - 1998/4/25 -
  XFree86 3.9Ag and 3.3.2</a></h1>

<p>This patch does the following:</p>

<ul>
    <li>implements a print-window facility for xterm. Though useful
    in itself, I added it as part of some debugging which I am
    doing. (Occasionally during an exposure event xterm fails to
    restore the proper colors for highlighted text, and printing
    the screen will show the internal states nicely).

<p>The print facility now also displays the color
      information. (I will probably make this a resource).</p>
    </li>

<li>modified the xterm-16color terminfo description to use the
    setaf and setab strings, which is a little more efficient
    (requested by Stephen Marley).</li>

<li>reduced some clutter of the ifdef/includes (e.g., stdlib.h,
    unistd.h, errno) making the configure script test for these.

<p>I removed the symbols Size_t and Time_t, since they no
      longer serve a useful purpose.</p>
    </li>

<li>added some debugging traces to show the initial screen
    size, and the success/failure of the ioctl calls pass handle
    window resizing events to the application (for Clint Olsen).

<p>I also modified the trace code to produce two files since
      some of the information is produced by the child process. So
      now they are Trace-parent.out and Trace-child.out</p>
    </li>

<li>updated configure test for ANSI compiler options to handle
    a special case for HP-UX 10.x (reported by Clint Olsen).</li>
  </ul>

<h1><a name="xterm_72" id="xterm_72">Patch #72 - 1998/4/17 -
  XFree86 3.9Ag and 3.3.2</a></h1>

<p>This is a patch from Chris Siebenmann
  &lt;cks@hawkwind.utcs.toronto.edu&gt;, which I have cleaned up a
  little, and integrated into the configure script.</p>

<p>From his description:</p>

<blockquote>
    <p>This set of patches is the latest incarnation of patches
    originally written by Ian! D Allen, then of the University of
    Waterloo and now of who knows where; I have been carrying them
    forward from xterm to xterm ever since about X11R4. What they
    do is add an option so that when an iconified xterm receives
    output it prepends '*** ' to its icon title and (optionally)
    beeps the bell; deiconifying the xterm removes the '*** '. Over
    the years I've found this to be incredibly convenient for
    monitoring all sorts of low-activity things.</p>
  </blockquote>

<h1><a name="xterm_71" id="xterm_71">Patch #71 - 1998/4/12 -
  XFree86 3.9Ag and 3.3.2</a></h1>

<p>This patch is a slightly modified version of one by Richard
  Braakman, which prevents buffer overflow in the input-method and
  preedit-type parsing in xterm. I changed a couple of details to
  make the code more maintainable, and looked for similar things -
  copying into a fixed-size buffer (found none, though I did spot
  an unused variable).</p>

<h1><a name="xterm_70" id="xterm_70">Patch #70 - 1998/3/29 -
  XFree86 3.9Af and 3.3.2</a></h1>

<p>This patch corrects some minor bugs in xterm, and fills in
  some more details in the VT220 emulation:</p>

<ul>
    <li>modify Imakefile to use SpecialCObjectRule for menu and
    data modules, making xterm build properly if logging is enabled
    (patch by Scott Sewall &lt;scott@iprg.nokia.com&gt;).</li>

<li>restore "ich" capability to terminfo entries, since Michael
    Schroeder points out that "ich1" is the one which is the
    problem in Solaris vi.</li>

<li>correct color of cursor, which would disappear on
    inverse-video since the initialization did not compare the
    cursor color against both foreground and background (reported
    by Olivier Calle).</li>

<li>correct abbreviation-test for -version and -help options,
    making command-line option -vb work (reported by Stefan
    Dalibor).</li>

<li>correct a dependency between ifdef's for OPT_I18N_SUPPORT
    and OPT_INPUT_METHOD (reported by Stefan Dalibor).</li>

<li>split-out character-set translations as new module
    charsets.c, to implement VT220 national replacement character
    sets (a mode where some of the characters are displayed as
    specific European glyphs). This relies on xterm using an ISO
    8859-1 font (approach suggested by Kenneth R. Robinette
    &lt;zkrr01@mailbox.neosoft.com&gt;).</li>

<li>correct a missing increment, which made SS2 and SS3
    controls repeat the shifted character.</li>

<li>add xterm-nrc to terminfo to illustrate the VT220 national
    replacement character sets.</li>

<li>reformat terminfo using new ncurses tic option "-f", which
    makes if/then/else/endif expressions easier to read.</li>
  </ul>

<h1><a name="xterm_69" id="xterm_69">Patch #69 - 1998/3/16 -
  XFree86 3.9Ad and 3.3.2</a></h1>

<p>This corrects the problem in xterm with utmp, reported by
  Olivier Calle &lt;olivier@tc.fluke.com&gt; as well as some other
  people after the XFree86 3.3.2 release.</p>

<p>The error was introduced by my patch #53 in XFree86 3.9r
  (October 1997).</p>

<p>The correction removes the reset of setuid/setgid before the
  main event loop, and solves the problem which I had worked around
  in a different manner: for some reason, the particular waitpid()
  call in creat_as() hangs, does not return when the child process
  exits. I changed the ifdef's to force the Linux configuration to
  use wait() instead. This call appears to work properly on other
  platforms such as SunOS and Solaris.</p>

<p>I also added tests in the standalone configure script to check
  for the existence of waitpid().</p>

<h1><a name="xterm_68" id="xterm_68">Patch #68 - 1998/3/4 -
  XFree86 3.9Ad and 3.3.1z</a></h1>

<p>This corrects another problem with the logic for
  highlightColor resource. As reported by David Dawes:</p>

<blockquote>
    <p>I've just noticed a problem with with the "inverse" control
    sequence (ESC[7m) with the 3.3.2 xterm. What it does is sets
    the background black, and the text the usual foreground colour
    rather than simply swapping the foreground/background.</p>
  </blockquote>

<p>This appears to be because when I added logic to check that
  the highlightColor was distinct from foreground and background
  colors, I did not add a further check to see that it was not
  black (I would make an explicit check for the resource not being
  set, but see nothing definite in the headers that would let me
  reference an explicitly-undefined Pixel value, though there are
  some implications in xpm.h). But this should work.</p>

<h1><a name="xterm_67" id="xterm_67">Patch #67 - 1998/2/23 -
  XFree86 3.9Ad and 3.3.1e</a></h1>

<p>This patch does the following:</p>

<ul>
    <li>improve test for highlightColor so that xterm does not
    attempt to use that unless it is different from the foreground
    and background colors (reported by Stefan Dalibor
    &lt;Stefan.Dalibor@informatik.uni-erlangen.de&gt;.

<p>I could not reproduce this until I noticed that the -rev
      option exposed it nicely.</p>
    </li>

<li>remove ich and ich1 from xterm and xterm-8bit terminfo
    descriptions. SVr4 terminfo documents that you must not combine
    these with smir/rmir, but ncurses allows it, opening a hole.
    Solaris 2.6 vi does not work properly if it is using a terminfo
    description when these are combined, since it was written to
    accommodate old terminals that required it (reported by Stephen
    Marley).</li>

<li>restore 1-pixel overlap of scrollbar border with left edge
    of window (reported by Jim Burmeister
    &lt;jimb@metrolink.com&gt;).</li>

<li>add a configure option, --enable-logfile-exec, which allows
    the user to specify a pipe for logfile. This defines
    ALLOWLOGFILEEXEC.</li>

<li>makes the ALLOWLOGFILEEXEC code compile &amp; run, if
    configured.</li>

<li>minor documentation nits.</li>
  </ul>

<h1><a name="xterm_66" id="xterm_66">Patch #66 - 1998/2/16 -
  XFree86 3.9Ad and 3.3.1d</a></h1>

<p>This fixes the problem reported with failure to build the
  <em>resize</em> program (BSDI, OSF/1) due to not having
  &lt;termcap.h&gt;, by changing the ifdef to one that would be set
  only if the file exists (not currently specified, except by the
  standalone configure script). We do not really need to include
  &lt;termcap.h&gt; to build, but only for a clean compile, since
  it may declare the tgetent() prototype. I also updated the
  man-page for <em>resize</em>, since I had recently noticed that
  it can be used to resize <em>xterm</em> using the "Sun" control
  sequences option.</p>

<h1><a name="xterm_65" id="xterm_65">Patch #65 - 1998/2/14 -
  XFree86 3.9Ad and 3.3.1c</a></h1>

<p>This is a small patch to xterm's 8-bit terminal description. I
  noticed while testing ncurses that I had specified the wrong
  (VT100-style) codes for the F1-F4. Xterm only uses VT220-style
  function keys in 8-bit mode.</p>

<h1><a name="xterm_64" id="xterm_64">Patch #64 - 1998/2/8 -
  XFree86 3.9Ad</a></h1>

<p>This fixes the following problems with xterm:</p>

<ul>
    <li>save/restore the ANSI foreground and background colors with
    the other visible attributes in the save-cursor and
    restore-cursor operations. This works around a problem with
    vim, which apparently assumed that switching between the normal
    and alternate screens resets the colors (reported by Jim Battle
    &lt;jb@chromatic.com&gt;).

<p>It would be nice to implement save/restore cursor as a
      stack (and solve this type of problem completely), but that
      would lead to incompatibility with applications which assume
      they are running with a VT100 or VT220.</p>
    </li>

<li>corrects behavior of a restore-cursor operation which does
    not follow a save-cursor (it is supposed to set the character
    sets to a known initial state).</li>

<li>extends the sunKeyboard resource (and menu toggle) to
    modify the home, end and delete keys on a Sun or PC editing
    keypad, making them generate codes compatible with DEC VT220's
    Find, Select and Remove keys.</li>

<li>corrects a length in checking command-line options, which
    caused the "-help" message to not work when X was not
    running.</li>

<li>add some detail to the man-page (requested by Jason Bacon
    &lt;acadix@execpc.com&gt;)</li>

<li>modify the standalone configure script to ignore the broken
    nsl and socket libraries on IRIX 6.2 (the ones on 5.2 also are
    broken, so this change just widens the check for the system
    version number).</li>
  </ul>

<h1><a name="xterm_63" id="xterm_63">Patch #63 - 1998/2/5 -
  XFree86 3.9Ad</a></h1>

<p>This is another patch from Bjorn Helgaas
  &lt;helgaas@rsn.hp.com&gt;, which I've reviewed (and learned
  some). Following are his notes:</p>

<p>I poked around some more and finally got xterm-62 to build and
  run cleanly on HP-UX 10.20. Here are the patches. They look sort
  of ugly, so here's a little explanation:</p>

<ul>
    <li>aclocal.m4: Removed side effects from the AC_CACHE_VAL
    commands in CF_FUNC_TGETENT. Previously, LIBS was set inside
    AC_CACHE_VAL, which worked fine the first time configure was
    run, but failed if there were cached values.</li>

<li>aclocal.m4: Added temporary setting of LIBS before
    AC_TRY_LINK in CF_FUNC_TGETENT. Previously, the last value set
    by the AC_TRY_RUN loop was used, so only -lcurses was
    checked.</li>

<li>configure.in: Added temporary setting of CPPFLAGS before
    AC_CHECK_HEADERS for X11 files. Previously
    &lt;X11/DECkeysym.h&gt; and &lt;X11/Xpoll.h&gt; were found only
    if they were in the compiler's default include directories,
    even if `--x-includes=DIR' had been used or AC_PATH_XTRA had
    found them elsewhere.</li>
  </ul>

<p>The problem on HP-UX was that we were linking with -lcurses
  rather than -ltermcap due to the second bullet above, and
  apparently something in HP-UX curses is broken. This seems very
  strange, because the only thing used is tgetent, which should
  affect any tty/pty configuration, but I lost interest in tracking
  down the exact problem.</p>

<h1><a name="xterm_62" id="xterm_62">Patch #62 - 1998/1/23 -
  XFree86 3.9Ac</a></h1>

<p>This is a patch mostly by Bjorn Helgaas
  &lt;helgaas@dhc.net&gt; (I added the os2main.c change, and a
  little of the documentation). From Bjorn's description:</p>

<ul>
    <li>If you use the "-hc &lt;color&gt;" option or set the
    "highlightColor" resource, text is highlighted by changing only
    the background color, rather than using reverse video. I find
    this easier to read, especially when selecting multi-colored
    text, and it is similar to the way Netscape shows
    selections.</li>

<li>Most of the code changes are under "#if
    OPT_HIGHLIGHT_COLOR". The principal exception is in screen.c,
    where I added a couple calls to resetXtermGC(). This seems like
    it could be a bug even without the color highlighting changes
    (though I don't pretend to understand all the logic).</li>
  </ul>

<h1><a name="xterm_61" id="xterm_61">Patch #61 - 1998/1/17 -
  XFree86 3.9Ac</a></h1>

<p>This patch modifies the reset behavior of xterm slightly:</p>

<ul>
    <li>change the terminfo entry so that rs1 (one of the strings
    used by the 'reset' program) does a hard reset rather than
    switching character sets. This is more in accord with other
    terminal descriptions.</li>

<li>modifies the treatment of hard reset by the xterm program
    to reset the saved lines.</li>

<li>corrects hard reset by also resetting user-defined keys,
    i.e., DECUDK.</li>
  </ul>

<h1><a name="xterm_60" id="xterm_60">Patch #60 - 1998/1/10 -
  XFree86 3.9Ab</a></h1>

<p>This fixes some minor bugs and adds new functionality:</p>

<ul>
    <li>add support for blinking text.

<ul>
        <li>This does not actually cause the text to flash, but
        text with the blink attribute can be displayed in color,
        using new resources colorBL and colorBLMode.</li>

<li>If colors are not used, the blinking text will be
        displayed as before (just like bold). The main purpose of
        this is to make applications work properly when they assume
        the emulator supports blinking text.</li>

<li>I did this by moving the per-cell LINEWRAPPED flag to a
        per-line flag, to make room for the new BLINK flag. There
        were no per-line flags, so this changes a lot of
        logic.</li>
      </ul>
    </li>

<li>corrected missing save-cursor logic in the handling of SGR
    1048 (the new control sequence I added in patch #54,
    1997/10/17). Reported by Darren Hiebert.</li>

<li>flush the output of the transparent printing after each
    line Reported by Tomas Vanhala
    &lt;vanhala@ling.helsinki.fi&gt;.</li>

<li>correct the modes that are affected by save/restore cursor
    by adding WRAPAROUND and PROTECTED.</li>

<li>corrected placement of one of the XSync calls that I added
    in patch #51, 1997/9/15, which had the side-effect of writing
    on the window border when the xterm was resizing from 132 to 80
    columns.</li>

<li>work around an incompatibility of the XKB definition used
    in xterm versus that symbol from IRIX 6.2's imake definitions
    (by adjusting the standalone configure script).</li>
  </ul>

<h1><a name="xterm_59" id="xterm_59">Patch #59 - 1998/1/5 -
  XFree86 3.9Ab</a></h1>

<p>My last patch has an off-by-one error in the comparison for
  argc. Douglas Kosovic &lt;douglask@dstc.edu.au&gt; showed me
  where (he got a core dump). Also, I think this explains Clint
  Olsen's problem, but the symptoms were more subtle (EINVAL for a
  system call if the -display option is omitted).</p>

<h1><a name="xterm_58" id="xterm_58">Patch #58 - 1998/1/3 -
  XFree86 3.9Ab</a></h1>

<p>This patch does the following:</p>

<ul>
    <li>implement logic to permit xterm to work with proportional
    fonts.

<ul>
        <li>Thomas Wolff &lt;Thomas.Wolff@sietec.de&gt; requested
        this (but it isn't exactly what he's asking for - that's a
        more involved task).</li>

<li>I chose to do this by rendering the characters on a
        fixed pitch, because it would not be useful for existing
        applications to display varying numbers of characters on
        each line.</li>

<li>Except that this forces the display to be wider, it
        works reasonably well. A couple of special cases (reverse +
        colorBD, for example) do not display with proper colors,
        since the inter-character gaps are painted with the
        background.</li>
      </ul>
    </li>

<li>added a version number to the program (several people have
    requested this).</li>

<li>make the -version and -help options interpreted before the
    program attempts to open the display.</li>

<li>minor reorganization of the man-page (ordered the options,
    resources and translations alphabetically - and eliminated some
    duplication).</li>

<li>corrected a misspelled filename in Makefile.in, and added a
    lint rule.</li>

<li>updated the configure script to correct behavior when it
    cannot find imake, as well as to fix the IRIX+gcc build
    (conflict with /usr/include).</li>

<li>regenerated the configure script with a newer patch to
    autoconf that fixes a problem with environment space vs the
    configure --help message.</li>
  </ul>

<h1><a name="xterm_57" id="xterm_57">Patch #57 - 1997/12/26 -
  XFree86 3.9Aa</a></h1>

<p>This patch is mostly concerned with the standalone configure
  script; a few minor corrections are added:</p>

<ul>
    <li>add configure option --disable-tek4014, to allow xterm to
    be built without the tek4014 emulation.</li>

<li>add configure option --with-terminal-type, to allow xterm
    to be compiled with default $TERM value other than "xterm"
    (e.g., "xterm-16color") -- requested by Stephen Marley
    &lt;stephen@memex.com&gt;.</li>

<li>fix a typo in the configure --help message -- reported by
    Darren Hiebert &lt;darren@hmi.com&gt;.</li>

<li>review diffs between main.c and os2main.c, to make them
    more alike. (applies some minor bug-fixes to OS/2's
    version).</li>

<li>add missing quotes in memmove/bcopy configure test</li>
  </ul>

<h1><a name="xterm_56" id="xterm_56">Patch #56 - 1997/11/28 -
  XFree86 3.9x</a></h1>

<p>This patch is based on analysis by Arfst Ludwig
  &lt;arfst@luxor.IN-Berlin.DE&gt;, who reported:</p>

<blockquote>
    <p>Setting the following resources xterm (all current versions)
    receives a segmentation fault on &lt;Btn2Up&gt; after
    scrolling:</p>

<pre>
          *XTerm*VT100*translations:    #override \
              ~Shift~Ctrl&lt;Btn2Up&gt;: insert-selection(PRIMARY, CUT_BUFFER0)\n\
              Shift~Ctrl&lt;Btn2Up&gt;:  insert-selection(CLIPBOARD, CUT_BUFFER1)\n\
              ~Shift&lt;BtnUp&gt;:       select-end(PRIMARY, CUT_BUFFER0)\n\
              Shift&lt;BtnUp&gt;:        select-end(CLIPBOARD, CUT_BUFFER1)
</pre>

<p>(The above resources intention is to be able to paste the
    latest selection even if the xterm was cleared.)</p>

<p>And here is how it works (and a fix!): The widget given to
    the action handler as first argument is not guaranteed to be a
    XtermWidget (it can be the ScrollbarWidget). Instead of
    accessing the widget's member directly XtDisplay gives the
    required pointer in a safe way.</p>
  </blockquote>

<p>I noticed that this was not the only instance (by reading the
  code, and testing with his example), and extended the solution to
  check the widget-class to ensure that it is indeed xterm's widget
  class before attempting to use it in the context of
  translations.</p>

<h1><a name="xterm_55" id="xterm_55">Patch #55 - 1997/11/25 -
  XFree86 3.9x</a></h1>

<p>This fixes the segmentation violation noted by Rogier Wolff
  about a month ago. He'd set xterm to 400 (rows) by 150 columns,
  which broke because there were limited buffers (200 rows) used
  for juggling data when adding or deleting lines and for switching
  between alternate and normal screens. I replaced this by an
  allocated buffer.</p>

<p>The bug is simple to test if you set titeInhibit false.</p>

<h1><a name="xterm_54" id="xterm_54">Patch #54 - 1997/10/17 -
  XFree86 3.9s</a></h1>

<p>This patch does the following:</p>

<ul>
    <li>correct a minor placement problem with the right
    scrollbar.</li>

<li>implement a new set of control sequences for switching
    between the normal and alternate VT100 screens. These work
    around the older sequences limitation that required
    modification of the runtime $TERMCAP to cooperate with the
    titeInhibit resource (that can't work with terminfo). I do this
    by moving all of the functionality of the rmcur terminfo

<h1><a name="xterm_53" id="xterm_53">Patch #53 - 1997/10/12 -
  XFree86 3.9r</a></h1>

<p>This patch adds a fix and implements a new feature (as well as
  some minor typos):</p>

<ul>
    <li>JCHANDRA@Inf.COM (JCHANDRA) noted that there was still a
    problem with the wait call with the logging option. It hung
    when the logfile was opened as a command-line option. I fixed
    this by moving the StartLogging() call down past the place
    where I'd reset the setuid mode. So the logfile is opened as
    the real user, without having to fork.</li>

<li>improve Rohleder's changes by renaming the command-line
    options and reducing the number of ifdef's.</li>

<li>implement right-scrollbars for xterm (patch by Michael
    Rohleder &lt;michael.rohleder@stadt-frankfurt.de&gt;).</li>
  </ul>

<h1><a name="xterm_52" id="xterm_52">Patch #52 - 1997/9/29 -
  XFree86 3.9q</a></h1>

<p>This patch addresses bugs and requests reported by</p>

<ul>
    <li>Bob Maynard &lt;rmaynard@montana.com&gt;,</li>

<li>Clint Olsen &lt;olsenc@ichips.intel.com&gt;,</li>

    &lt;Michael.Schroeder@informatik.uni-erlangen.de&gt;,</li>

<li>Pablo Ariel Kohan &lt;pablo@memco.co.il&gt;</li>
  </ul>

<p>Some of the changes are interrelated (it was an unusually busy
  week).</p>

<ul>
    <li>change the default resource value for colorMode to true,
    matching the Xterm.ad file.</li>

<li>correct behavior of 'ech' control, making the default and 0
    parameters erase one character rather than to the end of line
    (reported by Michael Schroeder).</li>

<li>add resource boldColors, command-line options +pc and -pc
    and configure-script option to specify behavior of xterm's
    mapping bold colors 0 through 7 to colors 8 through 15.
    (request by Pablo Ariel Kohan).</li>

<li>add resource colorAttrMode to specify whether colorULMode
    and colorBDMode can override the ANSI colors (report by Clint
    Olsen).</li>

<li>correct a conflict between colorULMode/colorBDMode versus
    ANSI colors, where exposure events would occasionally pick up
    the former (e.g., colorBD) rather than ANSI colors. Testing the
    colorAttrMode made this apparent, though it has been in the
    code since 3.2A (patch #35 in Jan 1997).</li>

<li>correct two problems with the optional logging support. On
    Linux at least, the waitpid call in creat_as hangs when the
    logging is toggled from the popup menu. Also, the mktemp
    template has the wrong number of X's (since X11R5!). Fixed the
    waitpid problem by exploiting the fact that the setuid behavior
    is reset before the popup menus are available. (reported by
    Jayachandran C.).</li>

<li>add configure script options for building with the Xaw3d
    and neXtaw libraries.</li>

<li>correct CF_IMAKE_CFLAGS standalone configure script macro,
    so that it will pick up $(ALLDEFINES) rather than
    $(STD_DEFINES). This is needed to make scrollbars work on
    Linux, since that uses narrow prototypes. (reported by Bob
    Maynard).</li>

<li>various minor updates to configure-script macros.</li>
  </ul>

<h1><a name="xterm_51" id="xterm_51">Patch #51 - 1997/9/15 -
  XFree86 3.9p</a></h1>

<p>Most of this patch is related to the standalone configure
  script, though there are fixes/enhancements as well:</p>

<ul>
    <li>add a new resource sunKeyboard, with associated
    command-line option and menu-toggle that allows using a normal
    Sun or PC keyboard to generated the complete DEC-style function
    keys and keypad.</li>

<li>correct a reversed foreground/background test in the
    control sequence that replies with the current SGR
    settings.</li>

<li>correct, by invoking XSync, a display problem that caused
    the program to not properly update newly exposed areas when a
    font change or 80/132 resize request was not completely
    accepted.</li>

<li>restructured autoconf macros (I made a library of all of
    the macros across the complicated configure scripts I'm working
    on).</li>

<li>use the autoconf config.guess and config.sub scripts to
    better identify the host-os.</li>

<li>improve the configure script that uses 'imake' as a
    fallback for definitions.</li>

<li>correct several instances of unsigned/signed mixed
    expressions.</li>
  </ul>

<p>I've tested the configure script on Linux, SunOS 4.1.3,
  Solaris 2.5.1, IRIX 5.2 and 6.2, AIX 3.2.5 and CLIX 3.1 (all but
  the last run properly as well).</p>

<h1><a name="xterm_50" id="xterm_50">Patch #50 - 1997/8/22 -
  XFree86 3.9m</a></h1>

<p>This is a collection of small fixes, and a couple of minor
  enhancements:</p>

<ul>
    <li>plug a security hole in the implementation of Media Copy
    (print) by invoking setuid just before the main loop.</li>

<li>add an ifdef'd include for &lt;sys/termio.h&gt; for HP-UX,
    which allows the program to process SIGWINCH events (this is a
    bug in X11R6.3)</li>

<li>add state-table entries for VT52 emulation to enter/exit
    keypad application mode.</li>

<li>disable the popup-menu entry for 8-bit controls when the
    terminal-id is less than 200 (e.g., VT52 or VT100).</li>

<li>ensure that the popup-menu entry for 8-bit controls is
    updated when the application enables/disables this mode,
    including the response to a full-reset.</li>

<li>implement VT300 DECBKM feature: set interpretation of the
    backarrow key to either backspace or delete. The initial
    setting is via resource; it can also be modified in the main
    popup menu.</li>

<li>implement VTxxx KAM (ISO AM), which allows a keyboard to be
    locked (i.e., the terminal discards input).</li>

<li>implement VTxxx SRM, which is used to control local echoing
    of input on the terminal.</li>

<li>add terminfo and termcap entries for xterm-8bit, a
    variation of the xterm description that uses 8-bit control
    characters.</li>

<li>add fallback definitions for Imakefile to allow it to work
    on some X11R5 systems that have no SpecialCObjectRule or
    ProgramTargetName macros.</li>

<li>add .c.o and .c.i rules to standalone Makefile.in</li>

<li>correct order of -lXmu and -lXext in standalone configure
    script.</li>

<li>add configure script options to allow selective disabling
    of active-icon, input-method and i18n code (mainly for users
    with X11R5 or an incomplete X11R6 configuration).</li>

<li>change menu-indices from #define's to enum values, thereby
    making it work better with the ifdef's for logging and
    active-icon (the X11R6.3 active-icon code is incorrectly
    ifdef'd; this corrects an error introduced by incorporating
    that code).</li>

<li>correct minor compile errors in the configuration where
    active-icon is not used.</li>

<li>add configure option to suppress echoing of long compiler
    commands</li>

<li>correct spelling of decTerminalID in configure script help
    message</li>

<li>use gcc __attribute__((unused)) to quiet warnings about
    unused parameters when compiling with -W (to make it simpler to
    find the real problems).</li>
  </ul>

<h1><a name="xterm_49" id="xterm_49">Patch #49 - 1997/8/10 -

  print-screen) control sequences.</p>

<h1><a name="xterm_48" id="xterm_48">Patch #48 - 1997/7/26 -
  XFree86 3.9j</a></h1>

<p>This patch does the following (all but the first affect only
  the standalone configure script):</p>

<ul>
    <li>minor correction to positioning of underlines for small
    (e.g., 5x8) font size.

<p>The existing behavior allowed underlines to be drawn
      outside the character-cell, so they weren't cleared properly
      under some circumstances.</p>
    </li>

<li>adds more special-case tokens to the standalone configure
    script's imake-option filter (e.g., "&amp;&amp;", since a "make
    -n main.o" on my IRIX system uses that shell construct).</li>

<li>adds a '--enable-logging' option for the standalone
    configure script.</li>

<li>adds check and ifdef's for the standalone configure script
    to allow for building on platforms with X11R6, which lacks
    Xpoll.h (introduced in X11R6.1).</li>
  </ul>

<h1><a name="xterm_47" id="xterm_47">Patch #47 - 1997/7/13 -
  XFree86 3.9i</a></h1>

<p>This patch does the following</p>

<ul>
    <li>corrects an indexing error in the doublesize character
    logic (button.c) that caused core dump (this was reported by J.
    Wunsch).</li>

<li>corrects the logic of ShowCursor when it is painting in a
    doublesize cell (charproc.c).</li>

<li>corrects, according to vttest, the behavior when switching
    to doublesize characters and back again (doublechr.c).</li>

<li>adds cbt (back_tab) to the terminfo description (this was
    something that I'd overlooked as applicable to curses
    optimization last summer).</li>

<li>corrects, for the standalone xmc test, the logic for
    disabling xmc.</li>
  </ul>

<h1><a name="xterm_46" id="xterm_46">Patch #46 - 1997/7/4 -
  XFree86 3.9h</a></h1>

<p>This is a patch to provide test-support for some work I'm
  doing on ncurses. It does not modify the normal configuration of
  xterm; the code is compiled if the standalone configure option
  "--enable-xmc-glitch" is specified.</p>

<h1><a name="xterm_45" id="xterm_45">Patch #45 - 1997/7/2 -
  XFree86 3.9h</a></h1>

<p>This fixes the problem reported with xterm's cursor color
  versus the background (the second chunk in this patch) and also
  removes some duplicate initialization of the cursor GC's. If the
  cursor color at startup is the same as the background, then xterm
  will use the reverse GC, ignoring the setting of the colorMode
  resource.</p>

<h1><a name="xterm_44" id="xterm_44">Patch #44 - 1997/6/22 -
  XFree86 3.9g</a></h1>

<p>This implements the first part of the VT100 doublesize
  characters for xterm, as well as fixing a handful of bugs:</p>

<ul>
    <li>the doublesize character support uses the normal font
    (using scaled fonts will be another patch) with blanks to
    simulate doublesize characters. This patch does most of the
    global changes that'll be required. I've hidden most of the
    details in macros and ifdef's so it's easy to configure out
    (part of the patch is a configure option for that
    purpose).</li>

<li>corrected limits in DeleteChar() function -- it's always
    ignored the size of the left border and scrollbar. I noticed
    this when working on the doublesize characters since the glitch
    was doubled in size (i.e., it wrapped some garbage around the
    right margin).</li>

<li>corrected 'memmove()' logic, for standalone builds (it
    referenced a malloc wrapper from my development library).</li>

<li>add a check for HideCursor() to prevent repeated screen
    updates (which can cause a spurious cursor glitch to appear,
    e.g., during scrolling). I noticed this with the 3.2A version
    (but only a few weeks ago, when I started working on this
    patch).</li>
  </ul>

<h1><a name="xterm_43" id="xterm_43">Patch #43 - 1997/6/10 -
  XFree86 3.9d</a></h1>

<p>Here's a fix for two problems:</p>

<ul>
    <li>modify handling of tgetent results in xterm and resize
    programs to make them tolerant of missing termcap file, or
    unknown terminal name. In this scheme, an explicit "-tn" option
    will succeed, overriding the fallback list.</li>

<li>a nit in the configure script (log extra information to
    help diagnose which case of the test-compile of tgetent was
    used).</li>
  </ul>

<h1><a name="xterm_42" id="xterm_42">Patch #42 - 1997/6/8 -
  XFree86 3.2Xl</a></h1>

<p>Bram Moolenaar reported that the cursor color changed
  unexpectedly while scrolling. The cause was that it used the same
  GC's as the logic that draws the ANSI colors. The bug only
  appears if the cursorColor resource isn't set, and has been
  present since the initial implementation early last year. (The
  same bug also appears in rxvt ;-). Here's a fix.</p>

<h1><a name="xterm_41" id="xterm_41">Patch #41 - 1997/5/28 -
  XFree86 3.2Xl</a></h1>

<p>Some nits found by Darren Hiebert (missing part of
  install-rule, incorrect assignment for --enable-color-mode
  option).</p>

<h1><a name="xterm_40" id="xterm_40">Patch #40 - 1997/5/26 -
  XFree86 3.2Xl</a></h1>

<p>Patch for the configure script's logic for obtaining imake
  predefined symbols.</p>

<h1><a name="xterm_39" id="xterm_39">Patch #39 - 1997/5/24 -
  XFree86 3.2Xl</a></h1>

<p>This patch does the following:</p>

<ul>
    <li>integrate the 16-color change for 'xterm'</li>

<li>minor fixes/clarification of tgetent in terminfo vs termcap
    to 'resize'</li>
  </ul>

<p>(both changes also modify the configure script)</p>

<h1><a name="xterm_38" id="xterm_38">Patch #38 - 1997/5/22 -
  XFree86 3.2Xh</a></h1>

<p>This implements a simple configuration script with autoconf
  (to which I'll add more options later). It does the
  following:</p>

<ul>
    <li>configures xterm to build with X11R5 (at least on SunOS
    4.1, Solaris 2.4, possibly IRIX - sorry network was down today,
    but I did test an earlier version yesterday).</li>

<li>enables/disables the configuration ifdef's for ANSI color
    and VT52 emulation.</li>
  </ul>

<p>It does not make tests for the things that imake does (that's
  another project), instead it uses a hybrid of the autoconf tests
  for libraries and adds imake's compiler options (which are
  necessary in some cases to get main.c to compile).</p>

<h1><a name="xterm_37" id="xterm_37">Patch #37 - 1997/5/7 -
  XFree86 3.9a</a></h1>

<p>This corrects a minor, but annoying error in the vt220
  emulation: the DECUDK is only supposed to be interpreted for
  _shifted_ function keys.</p>

<h1><a name="xterm_36" id="xterm_36">Patch #36 - 1997/1/16 -
  XFree86 3.2r</a></h1>

<p>This corrects something that I overlooked in patch #27
  (21-aug-1996), which is that when trimming the region to be
  repainted for the highlightSelection resource of xterm, I still
  have to paint the background past the highlighted region. This
  only happens when I first do a selection in a window that's
  partly off-screen, then move the window on-screen.</p>

<h1><a name="xterm_35" id="xterm_35">Patch #35 - 1997/1/7 -
  XFree86 3.2o</a></h1>

<p>This patch does the following:</p>

<ul>
    <li>combines the coding for foreground and background colors
    into a single byte, reducing the memory required to store
    saved-lines in color. (I'll take back that byte in a following
    patch to use to ensure the character-set, so there's no
    long-term decrease in memory use).</li>

<li>modifies the PF1-PF4 coding in termcap/terminfo. Because
    xterm is still by default emulating vt100, the function key
    codes are vt100-compatible (I overlooked this in patch #31). I
    also reformatted the whole terminfo file into a single-column,
    for consistency.</li>

<li>adds an interim xterm-vt220 description to accommodate the
    old and new styles of function-keys (though probably it'd be
    better to drop the old-style altogether).</li>
  </ul>

<h1><a name="xterm_34" id="xterm_34">Patch #34 - 1997/1/5 -
  XFree86 3.2o</a></h1>

<p>This patch does the following:</p>

<ul>
    <li>implement DECSTR (soft terminal reset). The biggest diff is
    due to adding another state table (note that there's only one
    useful state here, but it's only 256 bytes rather than 1k as it
    would have been before I reduced the size of state
    entries).</li>

<li>some minor tidying up (e.g., signed/unsigned use bitcpy,
    MODE_DECCKM, resetColor, resetCharsets). More is done in patch
    #35.</li>
  </ul>

<p>I got the description of DECSTR from a vt420 user's manual.
  I'll do some testing with vttest to ensure that there's nothing
  else to do than what was documented.</p>

<h1><a name="xterm_33" id="xterm_33">Patch #33 - 1996/11/24 -
  XFree86 3.2</a></h1>

<p>This adds to the reset-fix by Matthieu Herrb
  &lt;Mathieu.Herrb@mipnet.fr&gt; a small change to make xterm able
  to output 8-bit characters in VT100 mode. Applications that run
  on real VT100's don't do that anyway, and this feature should be
  removed sometime after finishing off the VT220 emulation (VT220's
  can do 8-bit characters). That would be a good time to change the
  default terminal-id to 220.</p>

<h1><a name="xterm_32" id="xterm_32">Patch #32 - 1996/11/21 -
  XFree86 3.2</a></h1>

<p>This implements the REP (repeat) control for xterm. That isn't
  part of the DEC VTxxx series, but is defined in ISO 6429. (Note
  that the base xterm terminal description is <em>not</em> changed
  -- I added a variant, "xterm-rep").</p>

<h1><a name="xterm_31" id="xterm_31">Patch #31 - 1996/11/16 -
  XFree86 3.2</a></h1>

<p>This implements vt52 emulation in xterm (ifdef'd so it can be
  removed). I've been using it for testing for the past month or
  so.</p>

<h1><a name="xterm_29" id="xterm_29">Patch #29 - 1996/9/15 -
  XFree86 3.1.2Gb</a></h1>

<p>This patch does the following:</p>

<ul>
    <li>corrects the restoration of color for bold/underline color
    mode</li>

<li>adds a resource 'decTerminalID' to control the reporting
    level of xterm (e.g., VT100, VT220).</li>

<li>uses the new resource to implement/correct the DA1, DA2 and
    DECRPTUI reports.</li>

<li>change valid-response code in DECRQSS from 0 to 1 (the
    manual says 0, but the VT420 terminal I've been testing on says
    1).</li>
  </ul>

<p>All of these changes are based on vttest 2.6</p>

<p>(Most of the volume in the patch is to add 2 more state tables
  for parsing the 2nd/3rd device-attribute controls).</p>

<h1><a name="xterm_28" id="xterm_28">Patch #28 - 1996/8/31 -
  XFree86 3.1.2F</a></h1>

<p>This patch corrects the following reported by Roland Rosenfeld
  &lt;roland@spinnaker.rhein.de&gt;:</p>

<ul>
    <li>handle SGR 22, 24 and 25 in combination with colorUL and
    colorBD resources. Also noted &amp; fixed reset of colored
    underline/bold with SGR 0.</li>

<li>a typo in the termcap (missing '['), from 3.1.2Dj (my

<p>This patch fixes one of my long-term gripes: xterm's selection

  older behavior).</p>

<h1><a name="xterm_26" id="xterm_26">Patch #26 - 1996/8/20 -

<p>Here's a patch to fix a problem with xterm's cut/paste and
  another to modify the appearance of the highlighting while
  selecting. (The changes are independent, so you can see if the

<h1><a name="xterm_25" id="xterm_25">Patch #25 - 1996/8/18 -
  XFree86 3.1.2Ei</a></h1>

<p>Here's a correction for two minor bugs that I picked up in
  testing, plus some lint (from Solaris 2.5) where NULL was used
  incorrectly:</p>

<ul>
    <li>make the second alternate font the same as the first
    (that's what vt420 and dtterm do)</li>

<li>corrected DECSCL report when DECSCL hasn't been set (i.e.,
    don't return a '60').</li>
  </ul>

<h1><a name="xterm_24" id="xterm_24">Patch #24 - 1996/8/11 -
  XFree86 3.1.2Ee</a></h1>

<p>This patch does several things. In effect, xterm can (I think)
  do a reasonably good job of emulating vt220 and vt320 terminals
  (as well as it was doing vt100, at any rate ;-).</p>

<ul>
    <li>soft fonts</li>

<li>rigel or sixel graphics</li>
  </ul>

<p>Anyway, I:</p>

<ul>
    <li>added ECH, CPL, CNL, SU, SD, CBT, CHT controls</li>

<li>added popup-menu for switching between DEC and Sun function
    keys. (corrected alignment err wrt logging entry at that
    point).</li>

<li>make xterm recognize both 8-bit and 7-bit controls
    (including popup menu for switching modes).</li>

<li>add user-definable function keys (aka DECUDK)</li>

<li>support concealed text</li>

<li>support protected text (both ISO compatible and DEC
    compatible - that's not the same thing, btw), with SPA, EPA,
    DECSCA, DECSED, DECSEL controls.</li>

<li>implement DECSCL.</li>
  </ul>

<p>I'll be continuing to test this patch for a while, but don't
  expect to add any new functionality (it passes all of the current
  tests I've built in vttest, but I need to make more tests)..</p>

<h1><a name="xterm_23" id="xterm_23">Patch #23 - 1996/7/31 -
  XFree86 3.1.2Ec</a></h1>

<p>This removes the blinking cursor I added last week (for
  performance reasons). Time-permitting, I'll revisit this after
  3.2 is released (there <em>will</em> be more work after XFree86
  3.2, I assume).</p>

<h1><a name="xterm_22" id="xterm_22">Patch #22 - 1996/7/26 -

<p>I looked more closely at my "double-negative" and realized
  that I had been confused by the default color scheme (black on
  white) in combination with reverse video. However, I did see that
  the original_fg and original_bg data weren't really used - so I
  removed that logic.</p>

<ul>
    <li>during initialization, check if ANSI colors are set with
    non fg/bg values, disable color mode if not. This makes xterm
    tolerant of applications that allocate the whole color
    map.</li>

<li>adjusts the shell's background color in ReverseVideo so

<li>adds an ifdef OPT_ISO_COLORS to allow configuring xterm
    without the ISO color support (saves a lot of memory)</li>

<li>used that ifdef to isolate/modify logic so that if the user
    doesn't have the colorMode enabled, then ISO color support is
    disabled (saving memory).

<p>(If anyone needs numbers, I had savedLines set to 2000,
      and found a reduction from ~700k to ~400k of allocated
      memory, according to Purify).</p>

<h1><a name="xterm_20" id="xterm_20">Patch #20 - 1996/7/24 -
  XFree86 3.1.2Ec</a></h1>

<p>This documents the changes in control sequences for window
  operations that I added in my previous patch. I'm testing another
  patch that allows the user to use less memory if colors aren't
  needed.</p>

<h1><a name="xterm_19" id="xterm_19">Patch #19 - 1996/7/21 -
  XFree86 3.1.2Ec</a></h1>

<p>This patch does the following:</p>

<ul>
    <li>fixes the core dump that I reported on IRIX 5.2 (in main.c)

<p>(it's worth noting that this bug exists in X11R6.1, so I'd
      like to assume that someone's already submitted a fix to X
      Consortium...)</p>
    </li>

<li>change the interpretation of zero rows or columns in a
    resize-window request to use the root window's size (looking
    more carefully at dtterm, that seems to be what it does).</li>

<li>change some memmove calls to memcpy for slightly better
    performance. also, a couple of memset calls to bzero, since
    Quantify says bzero runs 20% faster, I assume because there's
    one less argument.</li>

<li>interpret character sets 1 and 2 (so that vttest gives a
    reasonable result) Both rxvt and dtterm do something
    equivalent.</li>

<li>fix a minor memory leak in the logic that retrieves the
    window or icon names (Purify found this for me while I ran
    vttest).</li>
  </ul>

<h1><a name="xterm_18" id="xterm_18">Patch #18 - 1996/7/18 -
  XFree86 3.1.2Ec</a></h1>

<p>This implements the following:</p>

<ul>
    <li>escape sequences that act like the CDE dtterm's window
    operations (though I have implemented the default width and
    height -- I've seen a rather buggy dtterm running that seems to
    treat width=0 or height=0 literally -- maybe that's a feature,
    not a bug?)</li>

<li>minor tweak to the screen-repainting when resizing (I still
    cannot entirely get rid of flicker).</li>

<li>still more fixes to terminfo &amp; termcap (I corrected my
    error for the hpa code and added some other stuff by comparing
    to ncurses' description and rxvt's).</li>

<li>a tweak to the changes by Michael Rohleder for the color
    translation</li>

<li>re-order attribute codes to allow later implementation of
    protected fields (dtterm supposedly does this; it's probably
    more useful than blinking or invisible text -- that uses up all
    of the available bits without changing the attribute scheme
    radically).</li>
  </ul>

<h1><a name="xterm_17" id="xterm_17">Patch #17 - 1996/7/2 -
  XFree86 3.1.2Eb</a></h1>

<p>This patch implements for xterm several minor features from
  ISO 6429 which are useful for terminfo applications. The HPA and
  VPA control sequences allow cursor movement along a row or
  column, cutting down a little on the characters transmitted. The
  other codes allow resetting specific graphic rendition attributes
  without modifying the other attributes. (now if someone just had
  time to implement blinking cursors...)</p>

<h1><a name="xterm_16" id="xterm_16">Patch #16 - 1996/6/25 -
  XFree86 3.1.2Ea</a></h1>

<p>Adam Tla/lka &lt;atlka@pg.gda.pl&gt; told me a couple of weeks
  ago that I'd missed some of the background coloring in xterm. I
  investigated, and found that while I'd picked up on the
  clear-to-bottom and clear-to-end-of-line operations, I'd
  overlooked the insert/delete lines. Just so I wouldn't overlook
  any more of these, I updated a copy of vttest to test ISO colors
  and bce (background color erase). This patch introduces a new
  function, ClearCurBackground, whose calls replace the direct
  XClearArea calls that I'd overlooked. (There's also a few
  compiler warnings fixed, etc ;-)</p>

<h1><a name="xterm_15" id="xterm_15">Patch #15 - 1996/5/29 -

<p>This fixes the problem reported by David Dawes, by making the
  50msec select timeout for the Xaw3d arrow scrollbar a resource.
  (I made it a boolean for a variety of reasons -- to make it a

  logic).</p>

<h1><a name="xterm_14" id="xterm_14">Patch #14 - 1996/5/12 -
  XFree86 3.1.2Dj</a></h1>

<p>This patch brings the termcap and terminfo descriptions for
  xterm up to date. I made the following changes:</p>

<ul>
    <li>reformatted the terminfo description in a single-column
    (this is ok for terminfo, and will simplify future patches --
    can't do that for termcap, since it would impact buffer
    requirements on some systems).</li>

<li>omitted obsolete features in termcap to save a little space
    (bs, pt)</li>

<li>added color capabilities to termcap (ut, Co, NC, op, AB,
    AF)</li>

<li>corrected some capabilities (vi, ve)</li>

<li>added 'st' (set tab)</li>

<li>reduced function keys in termcap for 'xterm' to 12 because
    color capabilities makes that description larger than 1023
    characters.</li>

<li>created new termcap name 'xtermm' (monochrome) to match the
    terminfo list, and make that description have 20 function
    keys.</li>

<li>added corresponding color capabilities to terminfo (bce,
    colors, pairs, op, ncv, setab, setaf)</li>

<li>corrected corresponding capabilities in terminfo (civis,
    cnorm, rmcup, smcup)</li>

<li>added capabilities (el1, hts)</li>

<li>in both, corrected home/end keys to match the code
    correction made by Thomas Mueller in 3.1.2Bk

<p>=&gt; (I'm still considering modifying the code &amp;
      description to match the rxvt program).</p>
    </li>
  </ul>

<li>charproc.c

<ul>
        <li>renamed screen.colors[] array to screen.Acolors[] to
        more easily distinguish the non-ANSI colors from the ANSI
        colors.</li>

<li>moved logic of SGR_Save() into VTInitialize, getting
        rid of local private variables original_fg and
        original_bg.</li>

<li>moved some logic into getXtermForeground and
        getXtermBackground from SGR_Foreground, SGR_Background,
        etc.</li>

<li>corrected misleading 'row' to 'col' in case for CUF,

        colors)</li>
      </ul>
    </li>

<li>ptyx.h

<ul>

<li>util.c

<ul>
        <li>new functions getXtermForeground and getXtermBackground
        replace the macros GET_FG and GET_BG, with the added
        functionality of checking for the reverse-video status of

<h1><a name="xterm_10" id="xterm_10">Patch #10 - 1996/2/14 -
  XFree86 3.1.2Cd</a></h1>

<p>I observed an occasional glitch in the xterm's color behavior;
  a clear to end of line would get a color that had been used in a
  program that supposedly reset colors. I traced this down to the
  way xterm was modifying colors of GC's on the fly; it didn't
  restore the original color of the GC, even though it would later
  be used in functions (such as ClearRight) that assumed (my error)
  that the GC would have the current foreground or background
  color.</p>

<p>I fixed this by resetting the GC's colors with a new function
  'resetXtermGC()', and direct calls on
  SGR_Foreground/SGR_Background, as appropriate and using a new
  function 'updatedXtermGC()' to encapsulate the logic that
  modifies the GC's color. (I also removed some commented-out code
  that was trying to do this -- the problem was a little more
  obscure).</p>

<h1><a name="xterm_09" id="xterm_09">Patch #9 - 1996/2/10 -
  XFree86 3.1.2Cb</a></h1>

<p>This patch fixes the remaining problems that I had making
  xterm run with x11r5, as well as a couple of other bugs. It
  follows my patch from yesterday, that added ifdef's for some of
  the input-method resources.</p>

<ul>
    <li>corrected ifdef's that suppress the input-method code
    (doesn't exist in my x11r5, and xterm works adequately without
    it).</li>

<li>corrected fallback definition for 'Select()' macro (oops:
    I'd copied the wrong text...)</li>

<li>moved the declarations for the fd_set variables to
    data.[ch]</li>

<li>corrected an ifdef in resize.c (sunos 4.x doesn't have
    termcap.h)</li>

<li>corrected (in main.c) some unused/orphaned variables.</li>
  </ul>

<h1><a name="xterm_08" id="xterm_08">Patch #8 - 1996/2/9 -
  XFree86 3.1.2Cb</a></h1>

<p>This is mostly a documentation patch for xterm. It describes
  the color control sequences in more detail, and documents some
  other features of xterm that aren't described elsewhere.</p>

<p>I've also added a couple of ifdef's to fix (part of) the
  problem that I'm working on (making the program work properly on
  x11r5, where I'm doing memory testing -- I have a "good" version
  from mid-January, but my resync version doesn't work properly on
  x11r5). I'm not done with <em>that</em> yet.</p>

<h1><a name="xterm_07" id="xterm_07">Patch #7 - 1996/1/28 -
  XFree86 3.1.2n</a></h1>

<p>I did a (clean) build of 3.1.2n on Linux 1.2.13 (ELF). I've
  got an S3 card.</p>

<p>This fixes the following in the 3.1.2n xterm:</p>

<ul>
    <li>initialize cur_foreground, cur_background in charproc.c
    (Purify told me they weren't initialized).</li>

<li>add interpretation of codes 39, 49, to reset background and
    foreground to default value (I'm told that ISO 6429 does this;
    but I don't have a written reference -- yet -- can anyone help
    here?). Anyway, rxvt does it, and it'll solve my remaining
    color management problems.</li>

<li>shadowing of 'time' in menu.c</li>

<li>'Cardinal' vs 'int' in scrollbar.c</li>

<li>several changes to permit compile with X11R5 (the system
    that I've got Purify on won't be upgraded to X11R6 for a long
    time).</li>
  </ul>

<p>I built this version (with a minor nit that I'll patch soon)
  on SunOS 4.1.3 so that I can test it some more with Purify.</p>

<p><em>btw</em>: the changes made in Xpoll.h won't work on some
  older systems, because fd_set isn't a defined type (I've got one
  machine at least that this applies to).</p>

<h1><a name="xterm_06" id="xterm_06">Patch #6 - 1996/1/8</a></h1>

<p>This patch does all of the SGR foreground/background fixes
  (i.e., clearing the screen after an SGR color is set causes that
  color to be used in the foreground and/or background). If the
  FG_COLOR and/or BG_COLOR flags aren't set, then the xterm
  foreground and background default to the window's values. This
  usage is consistent with various types of hardware (especially
  the IBM PC), and is also used in rxvt.</p>

<ul>
    <li>charproc.c:

<ul>
        <li>add/use new macros GET_FG, GET_BG - n/c.</li>

<li>add/use new functions SGR_Foreground() and
        SGR_Background() to set corresponding colors in GC's, and
        to retain sense of "original" colors.

<p>=&gt; This makes redundant some of the corresponding
          logic in HideCursor to set the foreground and background,
          but I left it in since it <em>may</em> be fixing an
          unrelated requirement.</p>
        </li>

<li>set GC's in LoadNewFont() according to whether the SGR
        fg/bg colors are active.

<p>=&gt; This fixes some glitches in the accompanying
          resize, that leaves parts of the window in the original
          background color.</p>
        </li>
      </ul>
    </li>

<li>screen.c:

<ul>
        <li>modified ClearBufRows() to use the SGR fg/bg colors if
        they're set.</li>

<li>added function ScrnClearLines(), used this to replace
        portions of ScrnInsertLine() and ScrnDeleteLine(). The new
        function uses the SGR fg/bg colors if they're set.

<p>=&gt; Otherwise, selection after an index or reverse
          index will paint the wrong colors.</p>
        </li>

<li>modified ScrnDeleteChar() and ScrnInsertChar() to use
        SGR fg/bg colors.</li>
      </ul>
    </li>

<li>util.c:

<ul>
        <li>modified ClearRight() so that if either of the SGR
        fg/bg colors is set, we don't bzero the attributes and
        color arrays, but instead fill them with the appropriate
        codes.</li>

<li>modified ClearLeft to use SGR fg/bg colors.</li>

    </li>
  </ul>

<p>This patch modifies the object code, by replacing indexing
  expressions with temporary variables with the full indexing
  expression. At first glance, this seems inefficient (it did to me
  ;-), until remembering comments made in the compilers newsgroups
  that trying to "help" the compiler doesn't really work that well.
  A good optimizing compiler can do a better job than the
  programmer can. (There's a moral in the use of 'register'

<h1><a name="xterm_02" id="xterm_02">Patch #2 - 1996/1/7</a></h1>

<p>This is my second patch to xterm. It corrects most of the gcc
  warnings (except for some that are due to X header files ;-). I
  compared objects to keep track of the changes that don't affect
  the object code (n/c) versus those that do.</p>

<p>At this point, I'm compiling (fairly) clean with gcc
  options</p>

<pre>
        -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow -Wnested-externs
</pre>

<p>(I also compiled with -Wshadow, but while that found some
  things that I wanted to find, there's far too many warnings from
  the X headers to be usable in this context).</p>

<p>The changes:</p>

<ul>
    <li>Tekproc.c:

<ul>
        <li>parenthesized expression to avoid gcc warning --
        n/c.</li>

<li>corrected nested-extern declaration for Bool

<li>adjusted logic of VTparse so that gcc won't warn about
        setjmp clobbering parsestate -- changes object.</li>

<li>corrected initialization of 'scstype', which could have
        been clobbered by setjmp/longjmp - changes object.</li>

<li>corrected nested-extern declaration of 'term',
        'ProgramName' - n/c</li>
      </ul>
    </li>

<li>cursor.c:

<ul>
        <li>corrected nested-extern declaration of 'term' --

    </li>

<li>input.c:

<ul>
        <li>change interface of StringInput to assume size_t (i.e.,

        object</li>

<li>corrected nested-extern 'environ' - n/c</li>

<li>adjusted assignments to 'tty_got_hung' and 'no_dev_tty'
        so that gcc can see they won't be clobbered by the longjmp
        - changes object.</li>

<li>menu.c:

<ul>
        <li>removed redundant prototype for 'do_hangup()' --
        n/c.</li>

<li>renamed 'time' parameters to avoid gcc -Wshadow warning
        - n/c</li>
      </ul>
    </li>

<li>menu.h:

<ul>
        <li>renamed 'time' parameters to avoid gcc -Wshadow warning
        - n/c</li>
      </ul>
    </li>

<li>misc.c:

<ul>
        <li>corrected definition of 'HandleFocusChange()' --
        changes object</li>

<li>cast parameters in call to 'TekExpose()' -- n/c</li>

<li>corrected nested-extern declarations of 'term',
        'toplevel', ProgramName, and 'environ' -- n/c.</li>

<li>proto.h:

<ul>
        <li>moved definition of SIGNAL_T (and SIGNAL_RETURN) here
        from main.c, resize.c to allow use of this symbol in
        prototypes (mostly in xterm.h).</li>

<li>added definition 'Size_t' to use as corrected type for
        strncpy, malloc sizes - n/c.</li>
      </ul>
    </li>

<li>resize.c:

<ul>
        <li>moved SIGNAL_T definition to proto.h -- n/c.</li>

<li>screen.c:

<li>tabs.c:

<ul>
        <li>corrected nested-extern declaration of 'term' --
        n/c</li>
      </ul>
    </li>

<li>util.c:

<ul>
        <li>corrected/supplied parameters to 'TekExpose()' --
        changes object (note: 'TekExpose()' doesn't use its
        parameters).</li>

<li>corrected nested-extern declaration of
        'waiting_for_initial_map' -- n/c.</li>

<li>renamed 'term' parameters to avoid gcc -Wshadow warning
        - n/c</li>
      </ul>
    </li>

<li>xterm.h:

<ul>
        <li>prototype 'do_hangup()', 'HandleFocusChange()',
        'TekExpose()', 'Error()', 'Exit()' - forces changes in
        various places.</li>

<li>adjusted prototypes that pass 'Boolean' arguments to
        use 'int' (this is the "correct" ANSI approach to extended
        compiles; it's worth mentioning that gcc doesn't meet the
        ANSI spec here). I used gcc -Wconversion to find these, but
        there's a lot of unrelated warnings that are due to setting
        NARROWPROTO in the config - n/c.</li>

<li>renamed 'term' parameters to avoid gcc -Wshadow warning
        - n/c</li>
      </ul>
    </li>
  </ul>

<h1><a name="xterm_01" id="xterm_01">Patch #1 - 1996/1/6</a></h1>

<p>This is my first cleanup patch for xterm. It addresses all of
  the gcc warnings for -Wall, -Wmissing-prototypes and
  -Wstrict-prototypes that I can change without modifying the
  object code. (I'm compiling this with gcc 2.7.0 for an aout
  target, which makes it simple to compare objects. When I do
  ELF-only, I've got a tool that compares that sort of thing as
  well).</p>

<p>Briefly, this patch adds (and uses) two header files in the
  xterm directory:</p>

<pre>
        proto.h
        xterm.h
</pre>

<p>I expect this to be the biggest patch by far. However (barring
  a misplaced prototype), it shouldn't break anything, since the
  intent of the patch is to provide missing declarations.</p>
