+ remove trailing ';' from GCC_DEPRECATED definition.
+ repair a change from 20110730 which left an error-check/warning dead.
+ fix several minor Coverity warnings.
+ add deprecation warnings for internal functions called by older
versions of tack.
+ fix a special case in PutAttrChar() 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 vt52, which lacks most line-drawing capability.
+ use configure --with-config-suffix option to work around filename
conflict with Debian packages versus test-packages.
+ update tracemunch to work with perl 5.26.2, which changed the rules
for escaping regular expressions.
+ document new form-extension O_EDGE_INSERT_STAY (report by Leon
Winter).
+ correct error-returns listed in manual pages for a few form functions
(report by Leon Winter).
+ add a check in form-library for null-pointer dereference:
unfocus_current_field (form);
form_driver (form, REQ_VALIDATION);
(patch by Leon Winter).
+ modify form library to optionally delay cursor movement on a field
edge/boundary (patch by Leon Winter).
+ modify form library to avoid unnecessary update of cursor position in
non-public fields (patch by Leon Winter).
+ remove unused _nc_import_termtype2() function.
+ also add/improve null-pointer checks in other places
+ add a null-pointer check in _nc_parse_entry to handle an error when
a use-name is invalid syntax (report by Chung-Yi Lin).
+ clarify in manual pages that vwprintw and vwscanw are obsolete,
not part of X/Open Curses since 2007.
+ use "const" in some prototypes rather than NCURSES_CONST where X/Open
Curses was updated to do this, e.g., wscanw, newterm, the terminfo
interface. Also use "const" 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interface, which was withdrawn by X/Open Curses in Issue 5 (2007).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 "const" for certain return
values, e.g., keyname().
+ improve terminfo write/read by modifying the fourth item of the
extended header to denote the number of valid strings in the extended
string table (prompted by a comment in unibilium's sources).
+ amend Scaled256() macro in test/picsmap.c to cover the full range
0..1000 (report by Roger Pau Monne).
+ add some checks in tracemunch for undefined variables.
+ fix a check in infotocap which may not have detected a problem when
it should have.
+ add a check in tic for the case where setf/setb are given using
different strings, but provide identical results to setaf/setab.
+ further improve fix for terminfo.5 (patch by Kir Kolyshkin).
+ reorder loop-limit checks in winsnstr() in case the string has no
terminating null and only the number of characters is used (patch
by Gyorgy Jeney).
+ modify TurnOn/TurnOff macros in lib_vidattr.c and lib_vid_attr.c to
avoid expansion of "CUR" in trace.
+ improve a few lintian warnings in test-packages.
+ modify lib_setup to avoid calling pthread_self() without first
verifying that the address is valid, i.e., for weak symbols
(report/patch by Werner Fink).
+ modify generated terminfo.5 to not use "expand" and related width
on the last column of tables, making layout on wide terminals look
better (adapted from patch by Kir Kolyshkin).
+ add a category to report_offsets, 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.
+ simplify some ifdef's for extended-colors.
+ add NCURSES_GLOBALS and NCURSES_PRESCREEN to report_offsets, to show
how similar the different tinfo configurations are.
+ modify _nc_resolve_uses2() to detect incompatible types when merging
a "use=" clause of extended capabilities. The problem was seen in a
defective terminfo integrated from simpleterm sources in 20171111,
compounded by repair in 20180121.
+ correct Ss/Ms interchange in st-0.7 entry (tmux #1264) -TD
+ fix remaining flash capabilities with trailing mandatory delays -TD
+ correct cut/paste in NEWS (report by Sven Joachim).
+ improve fix for Debian #882620 by reusing limit2 variable (report by
Julien Cristau, Sven Joachim).
+ remove incorrect free() from 20170617 changes (report by David Macek).
+ correct type for "U8" in user_caps.5; it is a number not boolean.
+ add a null-pointer check in safe_sprintf.c (report by Steven Noonan).
+ improve fix for Debian #882620 by reusing limit2 variable (report
Julien Cristau, Sven Cristau).
+ modify misc/Makefile.in to install/uninstall explicit list in case
the build-directory happens to have no ".pc" files when an uninstall
is performed (report by Jeffrey Walton).
+ deprecate safe-sprintf, since the vsnprintf function, which does what
was needed, was standardized long ago.
+ add several development/experimental options to development packages.
+ minor reordering of options in configure script to make the threaded
and reentrant options distinct from the other extensions which are
normally enabled.
+ minor fixes to test/*.h to make them idempotent.
+ add/use test/parse_rgb.h to show how the "RGB" capability works.
+ add a clarification in user_caps.5 regarding "RGB" capability.
+ add extended_slk_color{,_sp} symbols to the appropriate
package/*.{map,sym} files (report by Sven Joachim, cf: 20170401).
+ updated release notes
+ amend a warning message from tic which should have flagged misuse
of "XT" capability in "screen" terminal description.

> merge branch begun April 2, 2017 which provides these features:
+ support read/write new binary-format for terminfo which stores
numeric capabilities as a signed 32-bit integer. The test programs
such as picsmap, ncurses were created or updated during 2017 to use
this feature.
+ the new format is written by the wide-character configuration of
tic when it finds a numeric capability larger than 32767.
+ other applications such as infocmp built with the wide-character
ncurses library work as expected.
+ applications built with the "narrow" (8-bit) configuration will
read the new format, but will limit those extended values to 32767.
+ in either wide/narrow configuration, the structure defined in
term.h still uses signed 16-bit values.
+ because it is incompatible with the legacy (mid-1980s) binary format,
a new magic value is provided for the "file" program.
+ the term.5 manual page is updated to describe this new format.
+ the limit on file-size for compiled terminfo is increased in the
wide-character configuration to 32768.
+ build-fix in picsmap.c for stdint.h existence.
+ add --disable-stripping option to configure scripts.
+ modify ncurses-examples to install test-scripts in the data directory.
+ work around tool-breakage in Debian 9 and later by invoking
gprconfig to specify the C compiler to be used by gnatmake,
and conditionally suppressing Library_Options line for static
libraries.
+ bump the compat level for test-packages to 7, i.e., Debian 5.
+ fixes for writing extended color pairs in putwin.
+ modify test/savescreen.c to add test patterns that exercise 88-,
256-, etc., colors.
+ modify configure option --with-build-cc, adding clang, c89 and c99
as possible default values.
+ modify ncurses-examples configure script to use pkg-config for the
extra form/menu/panel libraries, to be more consistent with the
handling of the curses/ncurses library.
+ modify test-packages for mingw to supply "pc" files.
+ modify gen-pkgconfig.in to list -lpthread as a private library when
configured to access it via weak symbols.
+ simplify gen-pkgconfig.in, adding -ltinfo without the special linker
checks because some versions of the linker simply hard-code the
behavior.
+ update URLs for ncurses website to use https.
+ modify CF_CURSES_LIBS to fill in $cf_nculib_root in case the
ncurses-examples are built with a system ncurses that lacks the
standard "curses" symbolic link, as done by SuSE. The symbol is
needed to make a followup check for the pthread library work, and
would be set properly using the options "--with-screen", etc.
+ generate misc/*.pc with "all" rule, as done for "sources" rule
(report by Jeffrey Walton).
+ build-fix for ncurses-examples with Fedora27, adding check for
reset_color_pairs() -- not yet in Fedora's package.
+ consistently add $CFLAGS to $MK_SHARED_LIB symbol in configure
script when the latter happens to use the C compiler rather than
directly using the loader (report by Jeffrey Walton).
+ set ABI for upcoming 6.1 release in "*.map" files. While there are
some remaining internals to apply, no ABI-related changes are
anticipated.
+ add configure --with-config-suffix option to work around filename
conflict with Redhat packages versus test-packages.
+ modify ncurses-examples to quiet const-warnings when building with
PDCurses.
+ modify toe to not exit if unable to read a terminal description,
e.g., if there is a permission problem.
+ minor fix for progs/toe.c, using _nc_free_termtype2.
+ assign 0 to pointer in _nc_tgetent_leak() after freeing it. Also
avoid reusing pointer from previous successful call to tgetent
if the latest call is unsuccessful (patch by Michael Schroeder,
OpenSuSE #1070450).
+ minor fix for test/tracemunch, initialize $awaiting variable.
+ repair template in test/package/ncurses-examples.spec (cf: 20171111).
+ improve tic's warning about the number of parameters tparm might use
for u1-u9 by making a special case for u6.
+ improve curs_attr.3x discussion of color pairs.
+ modify misc/ncurses-config.in to make output with --includedir
consistent with --cflags, i.e., when --disable-overwrite option was
configured the output should show the subdirectory where headers
are.
+ modify MKlib_gen.sh to suppress macros when calling an "implemented"
function in link_test.c
+ updated ftp-url used in test-packages, etc.
+ modify order of -pie/-shared options in configure script in case
LDFLAGS uses "-pie", working around a defect or limitation in the GNU
linker (prompted by patch by Yogesh Prasad, forwarded by Jay Shah).
+ add entry in man_db.renames for user_caps.5
+ modify MKlib_gen.sh to avoid tracing result from getstr/getnstr
before initialized.
+ add "-a" aspect-ratio option to picsmap.
+ add configure check for default path of rgb.txt, used in picsmap.
+ modify _nc_write_entry() to truncate too-long filename (report by
Hosein Askari, Debian #882620).
+ build-fix for ncurses-examples with NetBSD curses:
+ it lacks the use_env() function.
+ it lacks libpanel; a recent change used the wrong ifdef symbol.
+ add a macro for is_linetouched() and adjust the function's return
value to make it possible for most applications to check for an
error-return (report by Midolikawa H).
+ additional manpage cleanup.
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ add a note to curs_addch.3x on portability.
+ add a note to curs_pad.3x on the origin and portability of pads.
+ improve manpage description of getattrs (report by Midolikawa H).
+ improve manpage macros (prompted by discussion in Debian #880551.
+ reviewed test-programs using KEY_RESIZE, made fixes to test/worm.c
+ add a "-d" option to picsmap for default-colors.
+ modify old terminology entry and a few other terminal emulators to
account for xon -TD
+ correct sgr string for tmux, which used screen's "standout" code
rather than the standard code (patch by Roman Kagan)
+ correct sgr/sgr0 strings in a few other cases reported by tic, making
those correspond to the non-sgr settings where they differ, but
otherwise use ECMA-48 consistently:
jaixterm, aixterm, att5420_2, att4424, att500, decansi, d410-7b,
dm80, hpterm, emu-220, hp2, iTerm2.app, mterm-ansi, ncrvt100an,
st-0.7, vi603, vwmterm -TD
+ build-fix for diagnostics warning in lib_mouse.c for pre-5.0 versions
of gcc which did not recognize the diagnostic "push" pragma (patch by
Vassili Courzakis).
+ check for interrupt in color-pair initialization of dots_curses.c,
dots_xcurses.c
+ add z/Z zoom feature to test/ncurses.c C/c screens.
+ add '<' and '>' commands to test/ncurses.c S/s screens, to better
test off-by-ones in the overlap/copywin functions.
+ improve man/curs_inwstr.3x, correct end-logic for lib_inwstr.c
(report by Midolikawa H).
+ fix typo in a few places for "improvements" (patch by Sven Joachim).
+ clear the other half of a double-width character on which a line
drawing character is drawn.
+ make test/ncurses.c "s" test easier to understand which subtests are
available; add a "S" wide-character overlap test-screen.
+ modify test/ncurses.c C/c tests to allow for extended color pairs.
+ add endwin() call in error-returns from test/ncurses.c omitted in
recent redesign of its menu (cf: 20170923).
+ improve install of hashed-db by removing the ".db" file as done for
directory-tree terminal databases.
+ repair a few overlooked items in include/ncurses_defs from recent
port/refactoring of test-programs (cf: 20170909).
+ add test/padview.c, to compare pads with direct updates in view.c
+ modify test/view.c to expand tabs using the ncurses library rather
than in the test-program.
+ remove very old SIGWINCH example in test/view.c, just use KEY_RESIZE.
+ add -T, -e, -f -m options to "dots" test-programs.
+ fix a few typos in usage-messages for test-programs.
+ minor cleanup to test/view.c:
+ eliminate "-n" option by simply reading the whole file.
+ implement page up/down commands.
+ add check in tput for init/reset operands to ensure those use a
terminal.
+ improve manual pages which discuss chtype, cchar_t types and the
attribute values which can be stored in those types.
+ correct array-index when parsing "-T" command-line option in tabs
program.
+ modify demo_new_pair.c to pass extended pairs to setcchar().
+ add test/dots_xcurses.c to illustrate a different approach used for
extended colors which can be contrasted with dots_curses.c.
+ add a check in tic to note when a description uses non-mandatory
delays without xon_xoff. This is not an error, but some descriptions
for a terminal emulator may use the combination incorrectly.
+ modify "-T" option of clear and tput to call use_tioctl() to obtain
the operating system's notion of the screensize if possible.
+ review/repair some exit-codes for tput, making usage-message exit
with 2 rather than 1, and a failure to open terminal 4+errno.
+ amend check in tput, tabs and clear to allow those to use the
database-only features in cron if a -T option gives a suitable
terminal name (report by Lauri Tirkkonen).
+ correct an ifdef in test/ncurses.c for systems with soft-keys but
not slk_color().
+ regenerate man-html documentation.
+ fix a symbol conflict that made ncurses.c C/c menu not work with
Solaris xpg4 curses.
+ add refresh() call to dots_mvcur.c, needed to use mvcur() with
Solaris xpg4 curses after calling newterm().
+ minor fixes for configure script from work on ncurses-examples and
tin.
+ improve animation in test/xmas.c by adding a time-delay in blinkit().
+ modify several test programs to reflect that ncurses honors existing
signal handlers in initscr(), while other implementations do not.
+ modify bs.c to make it easier to quit.
+ change ncurses-examples to use attr_t vs chtype to follow X/Open
documentation more closely since Solaris xpg4-curses uses different
values for WA_xxx vs A_xxx that rely on attr_t being an unsigned
short. Tru64 aka OSF1, HPUX, AIX did as ncurses does, equating the
two sets.
+ modify menu for test/ncurses.c to fit on 24-line screen.
+ build-fix for configure --with-caps=uwin
+ add options to test_arrays.c, for selecting termcap vs terminfo, etc.
+ improve wide-character implementation of myADDNSTR() in frm_driver.c,
which was inconsistent with the normal implementation.
+ save/restore cursor position in Undo_Justification(), matching
behavior of Buffer_To_Window() (report by Leon Winter).
+ modify test/knight to provide the "slow" solution for small screens
using "R", noting that Warnsdorf's method is easily done with "a".
+ modify several test-programs which call use_default_colors() to
consistently do this only if "-d" option is given.
+ additional changes to test with non-standard variants of curses:
+ modify a loop limit in firework.c to work around absense of limit
checks in some libraries.
+ fill the last row of a window with "?" in firstlast if waddch does
not return ERR on the lower-right corner.
+ add checks in test/configure for some functions not in 4.3BSD curses.
+ fix a regression in test/configure (cf: 20170826).
+ amend change for endwin-state for better consistency with the older
logic (report/patch by Jeb Rosen, cf: 20170722).
+ modify check in fmt_entry() to handle a cancelled reset string
(Debian #873746). Make similar fixes in other parts of dump_entry.c
and tput.c
+ fixes for "iterm2" (report by Leonardo Brondani Schenkel) -TD
+ corrected a warning from tic about keys which are the same, to skip
over missing/cancelled values.
+ add check in tic for unnecessary use of "2" to denote a shifted
special key.
+ improve checks in trim_sgr0, comp_parse.c and parse_entry.c, for
cancelled string capabilities.
+ add check in _nc_parse_entry() for invalid entry name, setting the
name to "invalid" to avoid problems storing entries.
+ add/improve checks in tic's parser to address invalid input
+ add a check in comp_scan.c to handle the special case where a
nontext file ending with a NUL rather than newline is given to tic
as input (Redhat #1484274).
+ allow for cancelled capabilities in _nc_save_str (Redhat #1484276).
+ add validity checks for "use=" target in _nc_parse_entry (Redhat
#1484284).
+ check for invalid strings in postprocess_termcap (Redhat #1484285)
+ reset secondary pointers on EOF in next_char() (Redhat #1484287).
+ guard _nc_safe_strcpy() and _nc_safe_strcat() against calls using
cancelled strings (Redhat #1484291).
+ correct typo in curs_memleaks.3x (Sven Joachim).
+ improve test/configure checks for some curses variants not based on
X/Open Curses.
+ add options for test/configure to disable checks for form, menu and
panel libraries.
+ update "iterm" entry -TD
+ add "iterm2" entry (report by Leonardo Brondani Schenkel) -TD
+ regenerate llib-* files.
+ regenerate HTML manpages.
+ improve picsmap test-program:
+ reduce memory used for tsearch
+ add report in log file showing cumulative color coverage.
+ add -x option to clear/tput to make the E3 extension optional
(cf: 20130622).
+ add options -T and -V to clear command for compatibility with tput.
+ add usage message to clear command (Debian #371855).
+ improve usage messages for tset and tput.
+ minor fixes to "RDGB" extension and reset_color_pairs().
+ improve description of -R option in infocmp manual page (report by
Stephane Chazelas).
+ add reset_color_pairs() function.
+ add user_caps.5 manual page to document the terminfo extensions used
by ncurses.
+ improve build scripts, using SIGQUIT vs SIGTRAP; add other configure
script fixes from work on xterm, lynx and tack.
+ modify install-rule for ncurses-examples to put the data files in
/usr/share/ncurses-examples
+ improve tracemunch, by changing address-parameters of add_wch(),
color_content() and pair_content() to dummy parameters.
+ minor optimization to _nc_change_pair, to return quickly when the
current screen is marked for clearing.
+ in-progress changes to improve performance of test/picsmap.c for
loading image files.
+ modify allocation for SCREEN's color-pair table to start small, grow
on demand up to the existing limit.
+ add "RGB" extension capability for direct-color support, use this to
improve color_content().
+ improve picsmap test-program:
+ if no palette file is needed, attempt to load one based on $TERM,
checking first in the current directory, then by adding ".dat"
suffix, and finally in the data-directory, e.g.,
/usr/share/ncurses-examples
+ add "-l" option for logging
+ add "-d" option for debugging
+ add "-s" option for stepping automatically through list of images,
with time delay.
+ use tsearch to improve time for loading color table for images.
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ update interix entry using tack and SFU on Windows 7 Ultimate -TD
+ use ^? for kdch1 in interix (reported by Jonathan de Boyne Pollard)
+ add "rep" to xterm-new, available since 1997/01/26 -TD
+ move SGR 24 and 27 from vte-2014 to vte-2012 (request by Alain
Williams) -TD
+ add a check in newline_forces_scroll() in case a program moves the
cursor outside scrolling margins (report by Robert King).
+ improve _nc_tparm_analyze, using that to extend the checks made by
tic for reporting inconsistencies between the expected number of
parameters for a capability and the actual.
+ amend handling of repeat_char capability in EmitRange (adapted from
report/patch by Dick Wesseling):
+ translate the character to the alternate character set when the
alternate character set is enabled.
+ do not use repeat_char for characters past 255.
+ document "_nc_free_tinfo" in manual page, because it could be used in
tack for memory-leak checking.
+ add "--without-tack" configure option to refine "--with-progs"
configure option. Normally tack is no longer built in-tree, but
a few packagers combine it during the build. If term_entry.h is
installed, there is no advantage to in-tree builds.
+ adjust configure-script to define HAVE_CURSES_DATA_BOOLNAMES symbol
needed for tack 1.08 when built in-tree. Rather than relying upon
internal "_nc_" functions, tack now uses the boolean, number and
string capability name-arrays provided by ncurses and SVr4 Unix
curses. It still uses term_entry.h for the definitions of the
extended capability arrays.
+ add an overlooked null-pointer check in mvcur changes from 20170722
+ improve test-packages for ncurses-examples and AdaCurses for lintian
+ modify logic for endwin-state to be able to detect the case where
the screen was never initialized, using that to trigger a flush of
ncurses' buffer for mvcur, e.g., in test/dots_mvcur.c for the
term-driver configuration.
+ add dependency upon ncurses_cfg.h to a few other internal header
files to allow each to be compiled separately.
+ add dependency upon ncurses_cfg.h to tic's header-files; any program
using tic-library will have to supply this file. Legacy tack
versions supply this file; ongoing tack development has dropped the
dependency upon tic-library and new releases will not be affected.
+ modify command-line parameters for "convert" used in picsmap to work
with ImageMagick 6.8 and newer.
+ fix build-problem with tack and ABI-5 (Debian #868328).
+ repair termcap-format from tic/infocmp broken in 20170701 fixes
(Debian #868266).
+ reformat terminfo.src with 20170513 updates.
+ improve test-packages to address lintian warnings.
+ modify update_getenv() in db_iterator.c to ensure that environment
variables which are not initially set will be checked later if an
application happens to set them (patch by Guillaume Maudoux).
+ remove initialization-check for calling napms() in the term-driver
configuration; none is needed.
+ add help-screen to test/test_getstr.c and test/test_get_wstr.c
+ improve compatibility between different configurations of new_prescr,
fixing a case with threaded code and term-driver where c++/demo did
not work (cf: 20160213).
+ the fixes for Redhat #1464685 obscured a problem subsequently
reported in Redhat #1464687; the given test-case was no longer
reproducible. Testing without the fixes for the earlier reports
showed a problem with buffer overflow in dump_entry.c, which is
addressed by reducing the use of a fixed-size buffer.
+ add/improve checks in tic's parser to address invalid input
(Redhat #1464684, #1464685, #1464686, #1464691).
+ alloc_entry.c, add a check for a null-pointer.
+ parse_entry.c, add several checks for valid pointers as well as
one check to ensure that a single character on a line is not
treated as the 2-character termcap short-name.
+ fix a memory leak in delscreen() (report by Bai Junq).
+ improve tracemunch, showing thread identifiers as names.
+ fix a use-after-free in NCursesMenu::~NCursesMenu()
+ further amend incorrect calls for memory-leaks from 20170617 changes
(report by Allen Hewes).
+ modify c++/etip.h.in to accommodate deprecation of throw() and
throws() in c++17 (prompted by patch by Romain Geissler).
+ remove some incorrect calls for memory-leaks from 20170617 changes
(report by Allen Hewes).
+ add test-programs for termattrs and term_attrs.
+ modify _nc_outc_wrapper to use the standard output if the screen was
not initialized, rather than returning an error.
+ improve checks for low-level terminfo functions when the terminal
has not been initialized (Redhat #1345963).
+ modify make_hash to allow building with address-sanitizer,
assuming that --disable-leaks is configured.
+ amend changes for number_format() in 20170506 to avoid undefined
behavior when shifting (patch by Emanuele Giaquinta).
+ fill in some places where TERMTYPE2 vs TERMTYPE was not used
(report by Allen Hewes).
+ use ExitTerminfo() internally in error-exits for ncurses' setupterm
to help with leak checking.
+ use ExitProgram() in error-exit from initscr() to help with leak
checking.
+ review test-programs, adding checks for cases where the terminal
cannot be initialized.
+ add option "-xp" to picsmap.c, to use init_extended_pair().
+ make simple performance fixes for picsmap.c
+ improve aspect ratio of images read from "convert" in picsmap.c
+ add option to picsmap to use color-palette files, e.g., for mapping
to xterm-256color.
