<h3><a name="h3-library" id="h3-library">Library improvements</a></h3>
<h4><a name="h4-new-library" id="h4-new-library">New features</a></h4>
- <p>There are several new features:</p>
+ <p>These are new features:</p>
<ul>
<li>
- <p><a href=
- "@HOMEPAGE@/man/form_field_opts.3x.html">O_EDGE_INSERT_STAY</a>
- tells the form library to optionally delay cursor movement on
- a field edge/boundary</p>
- </li>
+ <p>The low-level terminfo and termcap interfaces are used
+ both by the higher-level curses library, as well as by many
+ applications.</p>
- <li>
- <p><a href=
- "@HOMEPAGE@/man/form_field_opts.3x.html">O_INPUT_FIELD</a>
- extension to form library allows a dynamic field to shrink if
- the new limit is smaller than the current field size.</p>
- </li>
+ <p>The functions which convert parameterized terminal
+ capability strings for output to the terminal
+ (<code>tiparm</code> and <code>tparm</code>) analyze the
+ capability string to determine which parameters are strings
+ (i.e., addresses), versus numbers (not addresses).</p>
- <li>
- <p>added <a href=
- "@HOMEPAGE@/man/curs_memleaks.3x.html">exit_curses</a> and
- <a href=
- "@HOMEPAGE@/man/curs_memleaks.3x.html">exit_terminfo</a> to
- replace internal symbols for leak-checking.</p>
- </li>
-
- <li>
- <p>added <a href=
- "@HOMEPAGE@/man/curs_trace.3x.html#h3-Functions">curses_trace</a>,
- to replace trace().</p>
- </li>
- </ul>
+ <p>The library's analysis of a capability string may differ
+ from the calling application's design if environment
+ variables are used to point to an invalid terminal database.
+ This is a longstanding problem with <em>all</em>
+ implementations of terminfo, dating from the early 1980s.</p>
- <p>Additionally, to improve performance other changes (and
- extensions) are provided in this release:</p>
+ <p>Two new functions address this problem: by providing a
+ function which allows the calling application to tell ncurses
+ how many string-parameters to expect:</p>
- <ul>
- <li>
- <p>mouse decoding now handles shift/control/alt logic when
- decoding xterm's 1006 mode</p>
- </li>
-
- <li>
- <p>ncurses now defines a limit for <a href=
- "@HOMEPAGE@/man/curs_getstr.3x.html">wgetnstr</a>, <a href=
- "@HOMEPAGE@/man/curs_get_wstr.3x.html">wgetn_wstr</a> when
- length is negative or “too large”.</p>
- </li>
-
- <li>reordered loop-limit checks in <a href=
- "@HOMEPAGE@/man/curs_insstr.3x.html">winsnstr</a> in case the
- string has no terminating null and only the number of
- characters is used.</li>
-
- <li>
- <p>there is now no buffer-size limit when reading the
- <a href="@HOMEPAGE@/man/ncurses.3x.html#h3-TERMCAP"><tt>$TERMCAP</tt></a>
- variable.</p>
- </li>
-
- <li>
- <p>the <a href=
- "@HOMEPAGE@/man/ncurses.3x.html#h3-TERMCAP"><tt>$TERMCAP</tt></a>
- variable may be interpreted as a fallback to a terminfo
- entry</p>
- </li>
+ <ul>
+ <li><code>tiscan_s</code> helps applications check
+ formatting capabilities that would be passed to
+ <code>tiparm_s</code>.</li>
- <li>
- <p><a href=
- "@HOMEPAGE@/man/curs_terminfo.3x.html#h3-Output-Functions"><tt>
- mvcur</tt></a> now decides whether to use hard-tabs, using
- <strong><tt>xt</tt></strong>, <strong><tt>tbc</tt></strong>
- and <strong><tt>hts</tt></strong> as clues.</p>
+ <li><code>tiparm_s</code> provides applications a way to
+ tell ncurses what the expected parameters are for a
+ capability.</li>
+ </ul>
</li>
<li>
- <p>extended colors are improved by modifying an internal call
- to <a href=
- "@HOMEPAGE@/man/curs_terminfo.3x.html#h3-Output-Functions"><tt>
- vid_puts</tt></a> to pass extended color pairs e.g., from
- <tt>tty_update.c</tt> and <tt>lib_mvcur.c</tt></p>
- </li>
+ <p>The ncurses library supports a compile-time feature
+ (enabled with the configure <code>--enable-check-size</code>
+ option) which simplifies initialization with terminals which
+ do not negotiate window (screen) size. This is done in
+ <code>setupterm</code>, by providing for using ANSI
+ cursor-position report (in user6/user7 terminfo capabilities)
+ to obtain the screen size if neither environment variables or
+ ioctl is used.</p>
- <li>
- <p id="getenv-fixes">the initialization functions now avoid
- relying upon persistent data for the result from <a href=
- "#getenv-check"><tt>getenv</tt></a></p>
+ <p>The ncurses test-program with options
+ “<code>-E -T</code>” demonstrates this
+ feature.</p>
</li>
- <li>
- <p>scrolling is improved:</p>
-
- <ul>
- <li>a limit check in <tt>newline_forces_scroll</tt> handles
- the case where the row is inside scroll-margins, but not at
- the end.</li>
-
- <li>
- <p>improved loop limits in <tt>_nc_scroll_window</tt>
- handle a case where the scrolled data is a pad which is
- taller than the window.</p>
- </li>
- </ul>
- </li>
+ <li>add functions to query tty-flags in
+ <code>SCREEN</code></li>
</ul>
+ <p>This release drops compatibility with obsolete versions of
+ <a href="@HOMEPAGE@/tack/">tack</a>, e.g., pre-1.08</p>
+
<h4><a name="h4-fixes-library" id="h4-fixes-library">Other
improvements</a></h4>
- <p>These are revised features:</p>
+ <p>These are improvements to existing features:</p>
<ul>
<li>
- <p>used “<tt>const</tt>” in some prototypes
- rather than <tt>NCURSES_CONST</tt> where X/Open Curses was
- updated to do this, e.g., <tt>wscanw</tt>, <tt>newterm</tt>,
- the terminfo interface. Also use “<tt>const</tt>”
- for consistency in the termcap interface, which was withdrawn
- by X/Open Curses in Issue 5 (2007). As of Issue 7, X/Open
- Curses still lacks “<tt>const</tt>” for certain
- return values, e.g., <a href=
- "@HOMEPAGE@/man/curs_util.3x.html#h3-keyname_key_name">keyname</a>.</p>
- </li>
-
- <li>
- <p>modified <a href=
- "@HOMEPAGE@/man/curs_bkgd.3x.html#h3-bkgd"><tt>wbkgd</tt></a>
- and <a href=
- "@HOMEPAGE@/man/curs_bkgrnd.3x.html#h3-bkgrnd"><tt>wbkgrnd</tt></a>
- to improve compatibility with SVr4 curses, changing the way
- the window rendition is updated when the background character
- is modified</p>
- </li>
-
- <li>
- <p>improved terminfo write/read by modifying the fourth item
- of the extended header to denote the number of valid strings
- in the extended string table (see <a href=
- "@HOMEPAGE@/man/term.5.html#h3-EXTENDED-STORAGE-FORMAT">term(5)</a>).</p>
- </li>
-
- <li>
- <p>modified the initialization checks for mouse so that the
- <a href=
- "/ncurses/terminfo.src.html#tic-xterm_sm_1006"><tt>xterm+sm+1006</tt></a>
- block will work with terminal descriptions not mentioning
- <em>xterm</em>.</p>
- </li>
- </ul>
+ <p>In addition to the new, safer function
+ <code>tiparm_s</code>, ncurses adds checks to make the older
+ <code>tiparm</code>, <code>tparm</code> and
+ <code>tgoto</code> functions safer:</p>
- <p>These were done to limit or ultimately deprecate features:</p>
+ <ul>
+ <li>
+ <p>the terminfo functions <code>tiparm</code> and
+ <code>tparm</code> ensure that the capability string
+ comes from the terminal description which ncurses loads,
+ rather than from random data which the application
+ happens to have.</p>
+ </li>
- <ul>
- <li>
- <p>deprecated <a href=
- "@HOMEPAGE@/NEWS.html#t970831">safe-sprintf</a>, since the
- <tt>vsnprintf</tt> function, which does what was needed, was
- standardized long ago.</p>
- </li>
+ <li>
+ <p>the <code>tgoto</code> function disallows capabilities
+ which its analysis shows will attempt to use string
+ parameters.</p>
+ </li>
- <li>
- <p>marked <a href=
- "@HOMEPAGE@/man/curs_printw.3x.html#h2-PORTABILITY"><tt>vwprintw</tt></a>
- and <tt>vwscanw</tt> as deprecated; recommend using <a href=
- "@HOMEPAGE@/man/curs_printw.3x.html"><tt>vw_printw</tt></a>
- and <tt>vw_scanw</tt>, respectively.</p>
+ <li>
+ <p>ncurses uses internal functions which correspond to
+ <code>tiparm</code>, and <code>tgoto</code> which ensure
+ that the capability strings which are passed to these
+ functions come from the loaded terminal description.</p>
+ </li>
+ </ul>
</li>
<li>
- <p>added deprecation warnings for internal functions called
- by older versions of <a href=
- "@HOMEPAGE@/tack.html">tack</a>.</p>
+ <p>improve check in <code>lib_tparm.c</code>, ensuring that a
+ char* fits into a <code>TPARM_ARG</code></p>
</li>
<li>
- <p>removed unused <tt>_nc_import_termtype2</tt> function.</p>
+ <p>modify <code>_nc_syserr_abort</code> to use
+ <code>_nc_env_access</code>, rather than only checking root
+ uid</p>
</li>
- </ul>
- <p>These are improvements to existing features:</p>
-
- <ul>
<li>
- <p>check parameter of <a href=
- "@HOMEPAGE@/man/curs_threads.3x.html">set_escdelay</a>,
- return ERR if negative.</p>
+ <p>improve thread lock in <code>lib_trace.c</code></p>
</li>
<li>
- <p>check parameter of <a href=
- "@HOMEPAGE@/man/curs_threads.3x.html">set_tabsize</a>, return
- ERR if not greater than zero</p>
+ <p>modify <code>flushinp</code> to use file descriptors in
+ <code>SCREEN</code>, rather than from <code>TERMINAL</code>,
+ and check if they are for a terminal, like SVr4</p>
</li>
<li>
- <p>correct a status-check in _nc_read_tic_entry() so that if
- reading a hex/b64 <a href=
- "@HOMEPAGE@/man/ncurses.3x.html#h3-TERMINFO"><tt>$TERMINFO</tt></a>,
- and the <a href=
- "@HOMEPAGE@/man/ncurses.3x.html#h3-TERM"><tt>$TERM</tt></a>
- does not match, fall-through to the compiled-in search
- list.</p>
+ <p>modify <code>mcprint</code> to use file descriptor in
+ <code>SCREEN</code>, for consistency</p>
</li>
<li>
- <p>amend check for <a href=
- "@HOMEPAGE@/man/terminfo.5.html#h3-Predefined-Capabilities"><tt>
- repeat_char</tt></a> to handle a case where setlocale() was
- called after <a href=
- "@HOMEPAGE@/man/curs_initscr.3x.html"><tt>initscr</tt></a></p>
+ <p>modify internal function <code>_nc_read_file_entry</code>
+ to show relevant filename in warnings</p>
</li>
<li>
- <p>move macro for <a href=
- "@HOMEPAGE@/man/curs_touch.3x.html"><tt>is_linetouched</tt></a>
- inside <strong><tt>NCURSES_NOMACROS</tt></strong>
- <em><tt>ifndef</tt></em>.</p>
+ <p>improve checks in internal function
+ <code>convert_string</code> for corrupt terminfo entry</p>
</li>
<li>
- <p>use <tt>_nc_copy_termtype2</tt> rather than direct
- assignment in <a href=
- "@HOMEPAGE@/man/curs_terminfo.3x.html#h3-Initialization">setupterm</a>,
- in case it is called repeatedly using fallback terminfo
- descriptions</p>
+ <p>review/improve handling of out-of-memory conditions</p>
</li>
<li>
- <p>improve workaround for Solaris wcwidth versus line-drawing
- characters</p>
+ <p>limit delays to 30 seconds, i.e., padding delays in
+ terminfo, as well as <code>napms</code> and
+ <code>delay_output</code> functions</p>
</li>
<li>
- <p>add checks in <a href=
- "@HOMEPAGE@/man/resizeterm.3x.html"><tt>repair_subwindows</tt></a>
- to keep the current position and scroll-margins inside the
- resized subwindow.</p>
+ <p>fix reallocation loop for <code>vsnprintf</code> in
+ <code>_nc_sprintf_string</code> by copying the va_list
+ variable</p>
</li>
<li>
- <p>correct a buffer-limit in <tt>write_entry.c</tt> for
- systems that use caseless filenames.</p>
+ <p>modify <code>delscreen</code> to limit the windows which
+ it creates to just those associated with the screen</p>
</li>
<li>
- <p>improved build-time utility <em>report_offsets</em>:</p>
-
- <ul>
- <li>
- <p>add categories, e.g., "w" for wide-character, "t" for
- threads to make the report more readable. Reorganized the
- structures reported to make the categories more
- apparent.</p>
- </li>
-
- <li>
- <p>add <tt>NCURSES_GLOBALS</tt> and
- <tt>NCURSES_PRESCREEN</tt> to report to show how similar
- the different <em>libtinfo</em> configurations are.</p>
- </li>
- </ul>
+ <p>modify <code>endwin</code> to return an error if it is
+ called again without an intervening screen update</p>
</li>
<li>
- <p>modified some header files to ensure that those include
- necessary files except for the previously-documented
- cases</p>
+ <p>modify <code>wenclose</code> to handle pads</p>
</li>
<li>
- <p>added some traces in initialization to show whether a
- fallback entry is used.</p>
+ <p>eliminate use of <code>PATH_MAX</code> in
+ <code>lib_trace.c</code></p>
</li>
<li>
- <p>made minor optimization to reduce calls to

</li>
</ul>
<ul>
<li>
- <p>fix a special case in <tt>PutAttrChar</tt> where a cell is
- marked as alternate-character set, but the terminal does not
- actually support the given graphic character. This would
- happen in an older terminal such as <em>vt52</em>, which
- lacks most line-drawing capability.</p>

- symbols</p>
- </li>
-
- <li>
- <p>add a couple of broken-linker symbols to the list of

</li>
<li>
- <p>improve <em>tracemunch</em>, by keeping track of
- <tt>TERMINAL*</tt> values, and if tracing was first turned on
- after initialization, attempt to show distinct screen, window
- and terminal names anyway.</p>
+ <p>corrected mouse mask in <code>test/testcurs.c</code></p>
</li>
<li>
- <p>modify <em>tracemunch</em> to accept filename parameters

</li>
<li>
- <p>update <em>tracemunch</em> to work with <em>perl

- expressions.</p>
+ <p>modify <code>test/test_mouse.c</code> to use curses api
+ for raw/noraw</p>
</li>
<li>
- <p>add some checks in <em>tracemunch</em> for undefined
- variables.</p>
- </li>
-
- <li>
- <p>modify <tt>TurnOn</tt>/<tt>TurnOff</tt> macros (in

<h3><a name="h3-bug-fixes" id="h3-bug-fixes">Interesting
bug-fixes</a></h3>
- <p>While there were many bugs fixed during development of ncurses
- 6.2, only a few (the reason for this release) were both important
- and interesting. Most of the bug-fixes were for local issues
- which did not affect compatibility across releases. Since those
- are detailed in the NEWS file no elaboration is needed here.</p>
+ <p>The changes to <tt>tparm</tt>, <tt>tgoto</tt> which improve
+ the design of the low-level interfaces are <em>interesting</em>,
+ but are not bug-fixes <em>per se</em>.</p>
- <p>The interesting bugs were in tic/infocmp's handling of
- user-defined capabilities. These were not recent bugs. Initially
- it was a simple problem:</p>
-
- <ul>
- <li>The user-defined capabilities can be any type (boolean,
- number or string), but once given a type all uses of the name
- must conform to that type—unless some special support for
- a particular multi-typed name is built into ncurses.</li>
-
- <li>
- <p>One of simpleterm's contributors copied some definitions
- for using <em>tmux</em>'s user-defined capabilities in
- <a href=
- "https://git.suckless.org/st/commit/06f8cf8ca87a81db15816658c40b2afcd1ad5332.html">

- </li>
+ <p>These are the major changes (aside from introducing <a href=
+ "#h4-new-library"><tt>tiparm_s</tt></a>):</p>
+ <ul>
<li>
- <p>Later, in (referring to a version from <a href=
- "https://git.suckless.org/st/commit/c0882f2ed1d7a2dd0fa2efa52157e6fc6fde3652.html">

- ncurses.</p>
+ <p>use wide-character (ncursesw) by default</p>
</li>
<li>
- <p>However, it had an error from the change in late 2016. The
- terminal description made what <em>tmux</em> expected to be
- <strong>string</strong> actually a
- <strong>boolean</strong>.</p>
-
- <p>Over the years, there were problems with each of
- simpleterm's terminal descriptions. I repaired those, and
- usually dealt with the problem.</p>
+ <p>use opaque typedefs by default</p>
</li>
+ </ul>
+
+ <p>However, most of the work on configure scripts was done to
+ reduce warnings within the configure script:</p>
+ <ul>
<li>
- <p>The difference in this case was that when compiling the
- terminal database, <em>tic</em> may have in memory the
- definitions for more than one terminal description (so that
- it can resolve “<tt>use=</tt>” clauses). Seeing
- two different types for the same name, in certain situations
- it would incorrectly merge the symbol tables for the two
- terminal descriptions.</p>
+ <p>intrusive warnings from GNU grep regarding fgrep and
+ egrep</p>
</li>
<li>
- <p>On simpleterm's side, their bug was finally fixed in
- <a href=
- "https://git.suckless.org/st/commit/83866428de031300eab03fbb116bcf7d2b1d4f60.html">
- late 2019</a>, three years after the bug was created.</p>
+ <p>fatal errors in compile-checks, arising from recent
+ “Modern C” efforts by some developers which
+ caused longstanding configure checks to fail.</p>
+
+ <p>After repairing the configure script, none of that
+ activity affected ncurses because stricter warnings are used
+ routinely in development.</p>
</li>
</ul>
- <p>For ncurses, the elapsed time to fix this bug was less than
- three years. Someone reported a problem with the terminal
- description a few weeks after releasing ncurses 6.1 (in <a href=
- "https://github.com/tmux/tmux/issues/1264">tmux #1264</a>), and
- the terminal description was updated that week (ncurses patch
- <a href="@HOMEPAGE@/NEWS.html#t20180224">20180224</a>):</p>
-
- <blockquote>
- <pre class="demo-name">

- + modify _nc_resolve_uses2() to detect incompatible types when merging
- a "use=" clause of extended capabilities. The problem was seen in a

- compounded by repair in 20180121.
- + correct Ss/Ms interchange in st-0.7 entry (tmux #1264) -TD
-</pre>
- </blockquote>
-
- <p>The larger part of that change added a check to prevent a
- simple merge of terminal descriptions where the same user-defined
- name was used with different types. But it raised some
- questions:</p>
+ <p>Other improvements made to configure checks include</p>
<ul>
<li>
- <p>Was there a reliable way to manage terminal descriptions
- which used the same extended name in different ways?</p>
+ <p>use <a href=
+ "@HOMEPAGE@/INSTALL.html#option:enable-string-hacks">string-hacks</a>
+ in alloc_entry.c, alloc_type.c and hardscroll.c, overlooked
+ due to compiler changes in recent OpenBSD releases</p>
</li>
<li>
- <p>Should ncurses provide a registry of well-known extended
- names, with their types?</p>
+ <p>revise progs.priv.h to provide for NC_ISATTY reuse</p>
</li>
- </ul>
-
- <p>Since the correction to <a href=
- "@HOMEPAGE@/ncurses.html#download_database"><tt>terminfo.src</tt></a>
- could have been readily adopted by packagers, there was nothing
- more to be done from ncurses' standpoint on that part. But
- improving ncurses to prevent issues like that is the reason for
- making a release.</p>
- <p>Nothing more (constructive) was mentioned with regard to
- simpleterm. But a few problems were found in the handling of
- user-defined capabilities:</p>
+ <li>
+ <p>configure check for MB_LEN_MAX provides warning as
+ needed</p>
+ </li>
- <ul>
<li>
- <p>Forward-references to user-defined capabilities in a
- “<tt>use=</tt>” clause did not allocate new data
- for each use. In <em>tic</em>, successive compilation of
- terminal entries could add user-defined capabilities to the
- wrong terminal entry.</p>
+ <p>trim a space after some "-R" options, fixing builds for
+ applications built using clang and ncurses on Solaris</p>
+ </li>
- <p>This was not noticed before, since xterm's terminal
- descriptions were the main users of the feature, and almost
- all of the uses of the building-blocks which contained
- user-defined capabilities were backward-references.</p>
+ <li>
+ <p>work around misconfiguration of MacPorts gcc13, which
+ exposes invalid definition of <tt>MB_LEN_MAX</tt> in gcc's
+ fallback copy of <tt>limits.h</tt></p>
</li>
<li>
- <p>There is one (documented) case where ncurses 6.1 supports
- a user-defined capability that could be any type (i.e.,
- “RGB”). The check added in February 2018 to guard
- against mismatches did not handle all of the combinations
- needed.</p>
+ <p>modified experimental Windows driver works with xterm
+ mouse protocol</p>
</li>
</ul>
- <p>Both of these issues dated from the original implementation of
- user-defined capabilities. Fixing them does not change the
- terminal database, but a older <em>tic</em> without the fixes
- will not be able to handle terminfo sources which rely upon those
- fixes. Starting in June 2019, the download link for the terminfo
- source file was capped at that date. The development sources have
- an up-to-date copy of the file, for people with a legitimate need
- for it.</p>
-
- <p>The “<tt>-c</tt>” (check) option of <em>tic</em>
- is not very useful if it cannot offer advice on parameters needed
- for user-defined capabilities. The various <em>Caps</em> files
- were reorganized to reduce redundancy, and in the common portion
- (<a href=
- "https://github.com/ThomasDickey/ncurses-snapshots/blob/master/include/Caps-ncurses">Caps-ncurses</a>),
- a registry of user-defined capabilities is provided for use by
- <em>tic</em>. While users can still define their own custom
- capabilities, <em>tic</em> will not offer any advice when their
- parameters do not match.</p>
-
- <p>In ncurses 6.2, <em>tic</em> makes a special check to allow
- any type for <em>RGB</em>, but its being able to do this relies
- upon fixes made in the ncurses library in mid-2019.</p>
