./devel/ncurses, CRT screen handling and optimization package

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 6.2nb1, Package name: ncurses-6.2nb1, Maintainer: pkgsrc-users

The ncurses (new curses) library is a free software emulation of
curses in System V Release 4.0, and more. It uses terminfo format,
supports pads and color and multiple highlights and forms characters
and function-key mapping, and has all the other SYSV-curses
enhancements over BSD curses.

ncurses: clean up patches

Remove cargo-cult packages, only keep the ones for renaming the
form/menu/panel libraries to gnu*.
Handle (removing) terminfo symlink in Makefile instead of as a patch.

No functional change intended.

	+ add --with-ada-libname option and modify Ada95 configuration to
	  allow renaming the "AdaCurses" library (prompted by proposed changes
	  by Pascal Pignard).
	+ modify configure script to distinguish gcc from icc and clang when
	  the --enable-warnings option is not used, to avoid unnecessary

	+ improve loop limits in _nc_scroll_window() to handle a case where
	  the scrolled data is a pad which is taller than the window (patch
	  by Rob King).
	+ amend the change to screen, because tmux relies upon that entry

	    supported, to try copying the pointers for va_list, or as an array.
	    Also add another fallback check, for __builtin_va_copy(), which
	    could be used with AIX xlc in c89 mode.

	  block will work with terminal descriptions not mentioning xterm
	  (report by Tomas Janousek).

	+ ignore the hex/b64 $TERMINFO in toe's listing.
	+ correct a status-check in _nc_read_tic_entry() so that if reading
	  a hex/b64 $TERMINFO, and the $TERM does not match, fall-through to
	  the compiled-in search list.

	  install (Debian #903790):
	  + use "install -p" when available, to avoid need for ranlib of
	    static libraries.
	  + modify scripts which use "--disable-relink" to add a 1-second
	    sleep to work around tools which use whole-second timestamps, e.g.,
	    in utime() rather than the actual file system resolution.

	+ remove ansi+rep mis-added to interix in 2018-02-23 -TD

	+ add enum, regex examples to test/demo_forms
	+ add configure check for pcre-posix library to help with MinGW port.

	+ build-fixes for gcc8.
	+ correct order of WINDOW._ttytype versus WINDOW._windowlist in
	+ fix a case where tiparm could return null if the format-string was
	  empty (Debian #902630).

	+ add acsc string to vi200 (Nibby Nebbulous)
	  add right/down-arrow to vi200's acsc -TD
	+ add "x" to tput's getopt string so that "tput -x clear" works
	  (Nicholas Marriott).
	+ minor fixes prompted by anonymous report on stack overflow:
	  + correct order of checks in _nc_get_locale(), for systems lacking
	    locale support.
	  + add "#error" in a few places to flag unsupported configurations

	+ use _WIN32/_WIN64 in preference to __MINGW32__/__MINGW64__ symbols
	  to simplify building with MSVC, since the former are defined in both
	  compiler configurations (report by Ali Abdulkadir).
	+ further improvements to configure-checks from work on dialog, i.e.,
	+ update config.guess, config.sub from

	+ build-fix for ncurses-examples related to gcc8-fixes (cf: 20180526).
	+ reduce use of _GNU_SOURCE for current glibc where _DEFAULT_SOURCE
	  combines with _XOPEN_SOURCE (Debian #900987).
	+ change target configure level for _XOPEN_SOURCE to 600 to address
	  use of vsscanf and setenv.
	+ improved configure-checks CF_SIZECHANGE and CF_STRUCT_TERMIOS from
	  work on dialog.

	+ modify generated ncurses*config and ncurses.pc, ncursesw.pc, etc.,
	  to list helper libraries such as gpm for static linking (Debian
	+ marked vwprintw and vwscanw as deprecated; recommend using vw_printw
	  and vw_scanw, respectively.

	+ add RPM test-package "ncursest-examples".
	+ modified RPM test-package to work with Mageia6.

	+ add note in curs_util.3x about unctrl.h
	+ review/improve header files to ensure that those include necessary
	  files except for the previously-documented cases (report by Isaac
	  Pascual Monells).
	+ improved test-package scripts, adapted from byacc 1.9 20180525.
	+ fix some gcc8 warnings seen in Redhat package build, but
	  work around bug in gcc8 compiler warnings in comp_parse.c

	+ formatting fixes for manpages, regenerate man-html documentation.
	+ trim spurious whitespace from tmux in 2018-02-24 changes;
	  fix some inconsistencies in/between tmux- and iterm2-entries for SGR
	  (report by C Anthony Risinger)
	+ improve iterm2 using some xterm features which it has adapted -TD
	+ add check in pair_content() to handle the case where caller asks
	  for an uninitialized pair (Debian #898658).

	+ 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
	+ 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.
	+ trim some redundant capabilities from st-0.7 -TD
	+ trim unnecessary setf/setb from interix -TD

	+ 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, \ 
	  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).

	+ 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 by
	  Julien Cristau, Sven Joachim).

	+ 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).

	+ update "VERSION" file, used in shared-library naming.
