+
+This is a log of changes that ncurses has gone through since Zeyd started
+working with Pavel Curtis' original work, pcurses, in 1992.
+
+Changes through 1.9.9e are recorded by Zeyd M. Ben-Halim.
+Changes since 1.9.9e are recorded by Thomas Dickey.
+
+19991023 5.0 release for upload to ftp.gnu.org
+ + effective with release of 5.0, change NCURSES_VERSION_PATCH to
+ 4-digit year.
+ + add function curses_version(), to return ncurses library version
+ (request by Bob van der Poel).
+ + remove rmam, smam from cygwin terminfo entry.
+ + modify FreeBSD cons25 terminfo entry to add cnorm and cvvis, as well
+ as update ncv to indicate that 'dim' conflicts with colors.
+ + modify configure script to use symbolic links for FreeBSD shared
+ libraries by default.
+ + correct ranf() function in rain and worm programs to ensure it does
+ not return 1.0
+ + hide the cursor in hanoi.c if it is running automatically.
+ + amend lrtest.c to account for optimizations that exploit margin
+ wrapping.
+ + add a simple terminfo demo, dots.c
+ + modify SIGINT/SIGQUIT handler to set a flag used in _nc_outch() to
+ tell it to use write() rather than putc(), since the latter is not
+ safe in a signal handler according to POSIX.
+ + add/use internal macros _nc_flush() and NC_OUTPUT to hide details
+ of output-file pointer in ncurses library.
+ + uncomment CC_SHARED_OPTS (see 971115), since they are needed for SCO
+ OpenServer.
+ + correct CC_SHARED_OPTS for building shared libraries for SCO
+ OpenServer.
+ + remove usleep() from alternatives in napms(), since it may interact
+ with alarm(), causing a process to be interrupted by SIGALRM (with
+ advice from Bela Lubkin).
+ + modify terminal_interface-curses-forms.ads.m4 to build/work with
+ GNAT 3.10 (patch by Juergen Pfeifer).
+ + remove part of CF_GPP_LIBRARY configure-script macro, which did not
+ work with gcc 2.7.2.3
+ + minor fix to test/tclock.c to avoid beeping more than once per second
+ + add 's' and ' ' decoding to test/rain.c
+
+991016 pre-release
+ + corrected BeOS code for lib_twait.c, making nodelay() function work.
+
+991009 pre-release
+ + correct ncurses' value for cursor-column in PutCharLR(), which was
+ off-by-one in one case (patch by Ilya Zakharevich).
+ + fix some minor errors in position_check() debugging code, found while
+ using this to validate the PutCharLR() patch.
+ + modify firework, lrtest, worm examples to be resizable, and to
+ recognize 'q' for quit, 's' for single-step and ' ' for resume.
+ + restore reverted change to terminal_interface-curses-forms.ads.m4,
+ add a note on building with gnat 3.10p to Ada95/TODO.
+ + add a copy of the standalone configure script for the test-directory
+ to simplify testing on SCO and Solaris.
+
+991002 pre-release
+ + minor fixes for _nc_msec_cost(), color_content(), pair_content(),
+ _nc_freewin(), ClrBottom() and onscreen_mvcur() (analysis by Philippe
+ Blain, comments by Alexander Lukyanov).
+ + simplify definition of PANEL and eliminate internal functions
+ _nc_calculate_obscure(), _nc_free_obscure() and _nc_override(),
+ (patch by Juergen Pfeifer, based on analysis by Philippe Blain
+ <bledp@voila.fr>)).
+ + change renaming of dft_fgbg.3x to use_default_colors.3ncurses in
+ man_db.renames, since Debian is not concerned with 14-character
+ filename limitation (from Debian bug report by Josip Rodin
+ <joy@cibalia.gkvk.hr>).
+ + corrected scoansi terminfo entry by testing with scoterm and console.
+ + revert change from 990614 to terminal_interface-curses-forms.ads.m4,
+ since this does not work for gnat 3.10p
+ + modify tclock example to be resizable (if ncurses' sigwinch handler
+ is used), and in color.
+ + use $(CC) rather than 'gcc' in MK_SHARED_LIB symbols, used for Linux
+ shared library rules.
+
+990925 pre-release
+ + add newer NetBSD console terminfo entries
+ + add amiga-8bit terminfo entry (from Henning 'Faroul' Peters
+ <Faroul@beyond.kn-bremen.de>)
+ + remove -lcurses -ltermcap from configure script's check for the gpm
+ library, since they are not really necessary (a properly configured
+ gpm library has no dependency on any curses library), and if the
+ curses library is not installed, this would cause the test to fail.
+ + modify tic's -C option so that terminfo "use=" clauses are translated
+ to "tc=" clauses even when running it as captoinfo.
+ + modify CF_STDCPP_LIBRARY configure macro to perform its check only
+ for GNU C++, since that library conflicts with SGI's libC on IRIX-6.2
+ + modify CF_SHARED_OPTS configure macro to support build on NetBSD with
+ ELF libraries (patch by Bernd Ernesti <bernd@arresum.inka.de>).
+ + correct a problem in libpanel, where the _nc_top_panel variable was
+ not set properly when bottom_panel() is called to hide a panel which
+ is the only one on the stack (report/analysis by Michael Andres
+ <ma@suse.de>, patch by Juergen Pfeifer).
+
+990918 pre-release
+ + add acsc string to HP 70092 terminfo entry (patch by Joerg Wunsch
+ <j@interface-business.de>).
+ + add top-level uninstall.data and uninstall.man makefile rules.
+ + correct logic of CF_LINK_FUNCS configure script, from BeOS changes so
+ that hard-links work on Unix again.
+ + change default value of cf_cv_builtin_bool to 1 as suggested by
+ Jeremy Buhler, making it less likely that a conflicting declaration
+ of bool will be seen when compiling with C++.
+
+990911 pre-release
+ + improved configure checks for builtin.h
+ + minor changes to C++ binding (remove static initializations, and make
+ configure-test for parameter initializations) for features not
+ allowed by vendor's C++ compilers (reported by Martin Mokrejs, this
+ applies to SGI, though I found SCO has the same characteristics).
+ + corrected quoting of ETIP_xxx definitions which support old versions
+ of g++, e.g., those using -lg++
+ + remove 'L' code from safe_sprintf.c, since 'long double' is not
+ widely portable. safe_sprintf.c is experimental, however, and
+ exists mainly as a fallback for systems without snprintf (reported
+ by Martin Mokrejs <mmokrejs@natur.cuni.cz>, for IRIX 6.2)
+ + modify definition of _nc_tinfo_fkeys in broken-linker configuration
+ so that it is not unnecessarily made extern (Jeffrey C Honig).
+
+990904 pre-release
+ + move definition for builtin.h in configure tests to specific check
+ for libg++, since qt uses the same filename incompatibly.
+ + correct logic of lib_termcap.c tgetstr function, which did not copy
+ the result to the buffer parameter. Testing shows Solaris does
+ update this, though of course tgetent's buffer is untouched (from
+ mpc.lists.freebsd.current newsgroup item by Peter Edwards
+ <peter.edwards@ireland.com>).
+ + corrected beterm terminfo entry, which lists some capabilities which
+ are not actually provided by the BeOS Terminal.
+ + add special logic to replace select() calls on BeOS, whose select()
+ function works only for sockets.
+ + correct missing escape in mkterm.h.awk.in, which caused part
+ of the copyright noticed to be omitted (reported by Peter
+ Wemm <peter@netplex.com.au>).
+ > several small changes to make the c++ binding and demo work on OS/2
+ EMX (related to a clean reinstall of EMX):
+ + correct library-prefix for c++ binding; none is needed.
+ + add $x suffix to make_hash and make_keys so 'make distclean' works.
+ + correct missing $x suffix for tack, c++ demo executables.
+ + split CF_CXX_LIBRARY into CF_GPP_LIBRARY (for -lg++) and
+ CF_STDCPP_LIBRARY (for -lstdc++)
+
+990828 pre-release
+ + add cygwin terminfo entry -TD
+ + modify CF_PROG_EXT configure macro to set .exe extension for cygwin.
+ + add configure option --without-cxx-binding, modifying the existing
+ --without-cxx option to check only for the C++ compiler
+ characteristics. Whether or not the C++ binding is needed, the
+ configure script checks for the size/type of bool, to make ncurses
+ match. Otherwise C++ applications cannot use ncurses.
+
+990821 pre-release
+ + updated configure macros CF_MAKEFLAGS, CF_CHECK_ERRNO
+ + minor corrections to beterm terminfo entry.
+ + modify lib_setup.c to reject values of $TERM which have a '/' in them.
+ + add ifdef's to guard against CS5, CS6, CS7, CS8 being zero, as more
+ than one is on BeOS. That would break a switch statement.
+ + add configure macro CF_LINK_FUNCS to detect and work around BeOS's
+ nonfunctional link().
+ + improved configure macros CF_BOOL_DECL and CF_BOOL_SIZE to detect
+ BeOS's bool, which is declared as an unsigned char.
+
+990814 pre-release
+ + add ms-vt100 terminfo entry -TD
+ + minor fixes for misc/emx.src, based on testing with tack.
+ + minor fix for test/ncurses.c, test 'a', in case ncv is not set.
+
+990731 pre-release
+ + minor correction for 'screen' terminfo entry.
+ + clarify description of errret values for setupterm in manpage.
+ + modify tput to allow it to emit capabilities for hardcopy terminals
+ (patch by Goran Uddeborg <goeran@uddeborg.pp.se>).
+ + modify the 'o' (panel) test in ncurses.c to show the panels in color
+ or at least in bold, to test Juergen's change to wrefresh().
+ > patches by Juergen Pfeifer:
+ + Fixes a problem using wbkgdset() with panels. It has actually
+ nothing to with panels but is a problem in the implementation of
+ wrefresh(). Whenever a window changes its background attribute to
+ something different than newscr's background attribute, the whole
+ window is touched to force a copy to newscr. This is an unwanted
+ side-effect of wrefresh() and it is actually not necessary. A changed
+ background attribute affects only further outputs of background it
+ doesn't mean anything to the current content of the window. So there
+ is no need to force a copy. (reported by Frank Heckenbach
+ <frank@g-n-u.de>).
+ + an upward compatible enhancement of the NCursesPad class in the C++
+ binding. It allows one to add a "viewport" window to a pad and then
+ to use panning to view the pad through the viewport window.
+
+990724 pre-release
+ + suppress a call to def_prog_mode() in the SIGTSTP handler if the
+ signal was received while not in curses mode, e.g., endwin() was
+ called in preparation for spawning a shell command (reported by Frank
+ Heckenbach <frank@g-n-u.de>)
+ + corrected/enhanced xterm-r5, xterm+sl, xterm+sl-twm terminfo entries.
+ + change test for xterm mouse capability: it now checks only if the
+ user's $DISPLAY variable is set in conjunction with the kmous
+ capability being present in the terminfo. Before, it checked if any
+ of "xterm", "rxvt" or "kterm" were substrings of the terminal name.
+ However, some emulators which are incompatible with xterm in other
+ ways do support the xterm mouse capability.
+ + reviewed and made minor changes in ncurses to quiet g++ warnings
+ about shadowed or uninitialized variables. g++ incorrectly warns
+ about uninitialized variables because it does not take into account
+ short-circuit expression evaluation.
+ + change ncurses 'b' test to start in color pair 0 and to show in the
+ right margin those attributes which are suppressed by no_color_video,
+ i.e., "(NCV)".
+ + modify ifdef's in curses.h so that __attribute__ is not redefined
+ when compiling with g++, but instead disabled the macros derived for
+ __attribute__ since g++ does not consistently recognize the same
+ keywords as gcc (reported by Stephan K Zitz <zitz@erf.net>).
+ + update dependencies for term.h in ncurses/modules (reported by
+ Ilya Zakharevich).
+
+990710 pre-release
+ + modify the form demo in ncurses.c to illustrate how to manipulate the
+ field appearance, e.g, for highlighting or translating the field
+ contents.
+ + correct logic in write_entry from split-out of home_terminfo in
+ 980919, which prevented update of $HOME/.terminfo (reported by Philip
+ Spencer <pspencer@fields.utoronto.ca>).
+
+990703 pre-release
+ + modify linux terminfo description to make use of kernel 2.2.x mods
+ that support cursor style, e.g., to implement cvvis (patch by Frank
+ Heckenbach <frank@g-n-u.de>)
+ + add special-case in setupterm to retain previously-saved terminal
+ settings in cur_term, which happens when curses and termcap calls are
+ mixed (from report by Bjorn Helgaas <helgaas@dhc.net>).
+ + suppress initialization of key-tries in _nc_keypad() if we are only
+ disabling keypad mode, e.g., in endwin() called when keypad() was not.
+ + modify the Ada95 makefile to ensure that always the Ada files from
+ the development tree are used for building and not the eventually
+ installed ones (patch by Juergen Pfeifer).
+
+990626 pre-release
+ + use TTY definition in tack/sysdep.c rather than struct termios
+ (reported by Philippe De Muyter).
+ + add a fallback for strstr, used in lib_mvcur.c and tack/edit.c,
+ not present on sysV68 (reported by Philippe De Muyter).
+ + correct definition in comp_hash.c to build with configure
+ --with-rcs-ids option.
+
+990619 pre-release
+ + modified ifdef's for sigaction and sigvec to ensure we do not try to
+ handle SIGTSTP if neither is available (from report by Philippe De
+ Muyter).
+ > patch by Philippe De Muyter:
+ + in tic.c, use `unlink' if `remove' is not available.
+ + use only `unsigned' as fallback value for `speed_t'. Some files used
+ `short' instead.
+
+990616 pre-release
+ + fix some compiler warnings in tack.
+ + add a check for predefined bool type in CC, based on report that
+ BeOS predefines a bool type.
+ + correct logic for infocmp -e option (i.e., the configure
+ --with-fallbacks option), which I'd not updated when implementing
+ extended names (cf: 990301). The new implementation adds a -E
+ option to infocmp.
+ > patch by Juergen Pfeifer:
+ + introduce the private type Curses_Bool in the Ada95 binding
+ implementation. This is to clearly represent the use of "bool" also
+ in the binding. It should have no effect on the generated code.
+ + improve the man page for field_buffer() to tell the people, that the
+ whole buffer including leading/trailing spaces is returned. This is
+ a common source of confusion, so it's better to document it clearly.
+
+990614 pre-release
+ > patch by Juergen Pfeifer:
+ + use pragma PreElaborate in several places.
+ + change a few System.Address uses to more specific types.
+ + change interface version-number to 1.0
+ + regenerate Ada95 HTML files.
+
+990612 pre-release
+ + modify lib_endwin.c to avoid calling reset_shell_mode(), return ERR
+ if it appears that curses was never initialized, e.g., by initscr().
+ For instance, this guards against setting the terminal modes to
+ strange values if endwin() is called after setupterm(). In the same
+ context, Solaris curses will dump core.
+ + modify logic that avoids a conflict in lib_vidattr.c between sgr0 and
+ equivalent values in rmso or rmul by ensuring we do not modify the
+ data which would be returned by the terminfo or termcap interfaces
+ (reported by Brad Pepers <brad@linuxcanada.com>, cf: 960706).
+ + add a null-pointer check for SP in lib_vidattr.c to logic that checks
+ for magic cookies.
+ + improve fallback declaration of 'bool' when the --without-cxx option
+ is given, by using a 'char' on i386 and related hosts (from discussion
+ with Alexander Lukyanov).
+
+990605 pre-release
+ + include time.h in lib_napms.c if nanosleep is used (patch by
+ R Lindsay Todd <toddr@rpi.edu>).
+ + add an "#undef bool" to curses.h, in case someone tries to define it,
+ e.g., perl.
+ + add check to tparm to guard against divide by zero (reported by Aaron
+ Campbell <aaron@ug.cs.dal.ca>).
+
+990516 pre-release
+ + minor fix to build tack on CLIX (mismatched const).
+ > patch by Juergen Pfeifer:
+ + change Juergen's old email address with new one in the files where it
+ is referenced. The Ada95 HTML pages are regenerated.
+ + update MANIFEST to list the tack files.
+
+990509 pre-release
+ + minor fixes to make 'tack' build/link on NeXT (reported by Francisco
+ A. Tomei Torres).
+
+990417 pre-release
+ + add 'tack' program (which is GPL'd), updating it to work with the
+ modified TERMTYPE struct and making a fix to support setaf/setab
+ capabilities. Note that the tack program is not part of the
+ ncurses libraries, but an application which can be distributed with
+ ncurses. The configure script will ignore the directory if it is
+ omitted, however.
+ + modify gpm mouse support so that buttons 2 and 3 are used for
+ select/paste only when shift key is pressed, making them available
+ for use by an application (patch by Klaus Weide).
+ + add complete list of function keys to scoansi terminfo entry - TD
+
+990410 pre-release
+ + add a simple test program cardfile.c to illustrate how to read form
+ fields, and showing forms within panels.
+ + change shared-library versioning for the Hurd to be like Linux rather
+ than *BSD (patch by Mark Kettenis <kettenis@wins.uva.nl>).
+ + add linux-lat terminfo entry.
+ + back-out _nc_access check in read_termcap.c (both incorrect and
+ unnecessary, except to guard against a small window where the file's
+ ownership may change).
+
+990403 pre-release
+ + remove conflicting _nc_free_termtype() function from test module
+ lib_freeall.c
+ + use _nc_access check in read_termcap.c for termpaths[] array (noted
+ by Jeremy Buhler, indicating that Alan Cox made a similar patch).
+ > patch by Juergen Pfeifer:
+ + modify menu creation to not inherit status flag from the default menu
+ which says that the associated marker string has been allocated and
+ should be freed (bug reported by Marek Paliwoda" <paliwoda@kki.net.pl>)
+
+990327 pre-release (alpha.gnu.org:/gnu/ncurses-5.0-beta1.tar.gz)
+ + minor fixes to xterm-xfree86 terminfo entry - TD.
+ + split up an expression in configure script check for ldconfig to
+ workaround limitation of BSD/OS sh (reported by Jeff Haas
+ <jmh@mail.msen.com>).
+ + correct a typo in man/form_hook.3x (Todd Miller).
+
+990318 pre-release
+ + parenthesize and undef 'index' symbol in c++ binding and demo, to
+ accommodate its definition on NeXT (reported by Francisco A. Tomei
+ Torres).
+ + add sigismember() to base/sigaction.c compatibility to link on NeXT
+ (reported by Francisco A. Tomei Torres).
+ + further refinements to inequality in hashmap.c to cover a case with
+ ^U in nvi (patch by Alexander Lukyanov).
+
+990316 pre-release
+ + add fallback definition for getcwd, to link on NeXT.
+ + add a copy of cur_term to tic.c to make it link properly on NeXT
+ (reported by Francisco A. Tomei Torres).
+ + change inequality in hashmap.c which checks the distance traveled by
+ a chunk so that ^D command in nvi (scrolls 1/2 screen) will use
+ scrolling logic (patch by Alexander Lukyanov, reported by Jeffrey
+ C Honig).
+
+990314 pre-release
+ + modify lib_color.c to handle a special case where the curscr
+ attributes have been made obsolete (patch by Alexander Lukyanov).
+ + update BSD/OS console terminfo entries to use klone+sgr and
+ klone+color (patch by Jeffrey C Honig).
+ + update glibc addon configure script for extended capabilities.
+ + correct a couple of warnings in the --enable-const configuration.
+ + make comp_hash build properly with _nc_strdup(), on NeXT (reported by
+ Francisco A. Tomei Torres <francisco.tomei@cwix.com>).
+
+990313 pre-release
+ + correct typos in linux-c initc string - TD
+ + add 'crt' terminfo entry, update xterm-xfree86 entry - TD
+ + remove a spurious argument to tparm() in lib_sklrefr.c (patch by
+ Alexander Lukyanov).
+
+990307 pre-release
+ + back-out change to wgetch because it causes a problem with ^Z
+ handling in lynx (reported by Kim DeVaughn).
+
+990306 pre-release
+ + add -G option to tic and infocmp, to reverse the -g option.
+ + recode functions in name_match.c to avoid use of strncpy, which
+ caused a 4-fold slowdown in tic (cf: 980530).
+ + correct a few warnings about sign-extension in recent changes.
+ > patch by Juergen Pfeifer:
+ + fixes suggested by Jeff Bradbury <jibradbury@lucent.com>:
+ + improved parameter checking in new_fieldtype().
+ + fixed a typo in wgetch() timeout handling.
+ + allow slk_init() to be called per newterm call. The internal SLK
+ state is stored in the SCREEN struct after every newterm() and then
+ reset for the next newterm.
+ + fix the problem that a slk_refresh() refreshes stdscr if the
+ terminal has true SLKs.
+ + update HTML documentation for Ada binding.
+
+990301 pre-release
+ + remove 'bool' casts from definitions of TRUE/FALSE so that statements
+ such as "#if TRUE" work. This was originally done to allow for a C++
+ compiler which would warn of implicit conversions between enum and
+ int, but is not needed for g++ (reported by Kim DeVaughn).
+ + add use_extended_names() function to allow applications to suppress
+ read of the extended capabilities.
+ + add configure option --enable-tcap-names to support logic which
+ allows ncurses' tic to define new (i.e., extended) terminal
+ capabilities. This is activated by the tic -x switch. The infocmp
+ program automatically shows or compares extended capabilities.
+ Note: This changes the Strings and similar arrays in the TERMTYPE
+ struct so that applications which manipulate it must be recompiled.
+ + use macros typeMalloc, typeCalloc and typeRealloc consistently
+ throughout ncurses library.
+ + add _nc_strdup() to doalloc.c.
+ + modify define_key() to allow multiple strings to be bound to the
+ same keycode.
+ + correct logic error in _nc_remove_string, from 990220.
+ > patch by Juergen Pfeifer, for Ada95 binding:
+ + regenerate some of the html documentation
+ + minor cleanup in terminal_interface-curses.adb
+
+990220 pre-release
+ + resolve ambiguity of kend/kll/kslt and khome/kfnd/kich1 strings in
+ xterm and ncsa terminfo entries by removing the unneeded ones. Note
+ that some entries will return kend & khome versus kslt and kfnd, for
+ PC-style keyboards versus strict vt220 compatiblity - TD
+ + add function keybound(), which returns the definition associated with
+ a given keycode.
+ + modify define_key() to undefine the given string when no keycode is
+ given.
+ + modify keyok() so it works properly if there is more than one string
+ defined for a keycode.
+ + add check to tic to warn about terminfo descriptions that contain
+ more than one key assigned to the same string. This is shown only if
+ the verbose (-v) option is given. Moved related logic (tic -v) from
+ comp_parse.c into the tic program.
+ + add/use _nc_trace_tries() to show the function keys that will be
+ recognized.
+ + rename init_acs to _nc_init_acs (request by Alexander Lukyanov).
+ > patch by Juergen Pfeifer, for Ada95 binding:
+ + remove all the *_adabind.c from ncurses, menu and form projects.
+ Those little helper routines have all been implemented in Ada and are
+ no longer required.
+ + The option handling routines in menu and form have been made more
+ save. They now make sure that the unused bits in options are always
+ zero.
+ + modify configuration scripts to
+ + use gnatmake as default compiler name. This is a safer choice than
+ gcc, because some GNAT implementations use other names for the
+ compilerdriver to avoid conflicts.
+ + use new default installation locations for the Ada files according
+ to the proposed GNU Ada filesystem standard (for Linux).
+ + simplify the Makefiles for the Ada binding
+ + rename ada_include directory to src.
+
+990213
+ + enable sigwinch handler by default.
+ + disable logic that allows setbuf to be turned off/on, because some
+ implementations will overrun the buffer after it has been disabled
+ once.
+
+990206
+ + suppress sc/rc capabilities from terminal description if they appear
+ in smcup/rmcup. This affects only scrolling optimization, to fix a
+ problem reported by several people with xterm's alternate screen,
+ though the problem is more general.
+ > patch by Juergen Pfeifer, for Ada95 binding:
+ + removed all pragma Preelaborate() stuff, because the just released
+ gnat-3.11p complains on some constructs.
+ + fixed some upper/lower case notations because gnat-3.11p found
+ inconsistent use.
+ + used a new method to generate the HTML documentation of the Ada95
+ binding. This invalidates nearly the whole ./Ada95/html subtree.
+ Nearly all current files in this subtree are removed
+
+990130
+ + cache last result from _nc_baudrate, for performance (suggested by
+ Alexander Lukyanov).
+ + modify ClrUpdate() function to workaround a problem in nvi, which
+ uses redrawwin in SIGTSTP handling. Jeffrey C Honig reported that
+ ncurses repainted the screen with nulls before resuming normal
+ operation (patch by Alexander Lukyanov).
+ + generalize is_xterm() function a little by letting xterm/rxvt/kterm
+ be any substring rather than the prefix.
+ + modify lib_data.c to initialize SP. Some linkers, e.g., IBM's, will
+ not link a module if the only symbols exported from the module are
+ uninitialized ones (patch by Ilya Zakharevich, who says that he has
+ seen messages claiming this behaviour conforms to the standard.)
+ + move call on _nc_signal_handler past _nc_initscr, to avoid a small
+ window where Nttyb hasn't yet been filled (reported by Klaus Weide).
+ + modify lib_tstp.c to block SIGTTOU when handling SIGTSTP, fixes a
+ problem where ncurses applications which were run via a shell script
+ would hang when given a ^Z. Also, check if the terminal's process
+ group is consistent, i.e., a shell has not taken ownership of it,
+ before deciding to save the current terminal settings in the SIGTSTP
+ handler (patch by Klaus Weide).
+ + correct spelling of ACS_ names in curs_border.3x (reported by Bob van
+ der Poel <bvdpoel@kootenay.com>).
+ + correct a couple of typos in the macros supporting the configure
+ --with-shlib-version option.
+
+990123
+ + modify fty_regex.c to compile on HAVE_REGEXPR_H_FUNCS machine (patch
+ by Kimio Ishii <ishii@csl.sony.co.jp>).
+ + rename BSDI console terminfo entries: bsdos to bsdos-pc-nobold, and
+ bsdos-bold to bsdos-pc (patch by Jeffrey C Honig).
+ + modify tput to accept termcap names as an alternative to terminfo
+ names (patch by Jeffrey C Honig).
+ + correct a typo in term.7 (Todd Miller).
+ + add configure --with-shlib-version option to allow installing shared
+ libraries named according to release or ABI versions. This
+ parameterizes some existing logic in the configure script, and is
+ intended for compatiblity upgrades on Digital Unix, which used
+ versioned libraries in ncurses 4.2, but no longer does (cf: 980425).
+ + resync configure script against autoconf 2.13 + patches
+ + minor improvements for teraterm terminfo entry based on the program's
+ source distribution.
+
+990116
+ + change default for configure --enable-big-core to assume machines do
+ have enough memory to resolve terminfo.src in-memory.
+ + correct name of ncurses library in TEST_ARGS when configuring with
+ debug library.
+ + minor fixes to compile ncurses library with broken-linker with g++.
+ + add --enable-broken-linker configure option, default to environment
+ variable $BROKEN_LINKER (request by Jeffrey C Honig).
+ + change key_names[] array to static since it is not part of the curses
+ interface (reported by Jeffrey C Honig <jch@bsdi.com>).
+
+990110
+ + add Tera Term terminfo entry - TD
+
+990109
+ + reviewed/corrected macros in curses.h as per XSI document.
+ + provide support for termcap PC variable by copying it from terminfo
+ data and using it as the padding character in tputs (reported by
+ Alexander Lukyanov).
+ + corrected iris-ansi and iris-ansi-ap terminfo entries for kent and
+ kf9-kf12 capabilities, as well as adding kcbt.
+ + document the mouse handling mechanism in menu_driver and make a small
+ change in menu_driver's return codes to provide more consistency
+ (patch by Juergen Pfeifer).
+ + add fallback definition for NCURSES_CONST to termcap.h.in (reported
+ by Uchiyama Yasushi <uch@nop.or.jp>).
+ + move lib_restart.c to ncurses/base, since it uses curses functions
+ directly, and therefore cannot be used in libtinfo.so
+ + rename micro_char_size to micro_col_size, adding #define to retain
+ old name.
+ + add set_a_attributes and set_pglen_inch to terminfo structure, as per
+ XSI and Solaris 2.5.
+ + minor makefile files to build ncurses test_progs
+ + update html files in misc directory to reflect changes since 4.2
+
+990102
+ + disable scroll hints when hashmap is enabled (patch by Alexander
+ Lukyanov).
+ + move logic for tic's verify of -e option versus -I and -C so that the
+ terminfo data is not processed if we cannot handle -e (reported by
+ Steven Schwartz <steves@unitrends.com>.
+ + add test-driver traces to terminfo and termcap functions.
+ + provide support for termcap ospeed variable by copying it from the
+ internal cur_term member, and using ospeed as the baudrate reference
+ for the delay_output and tputs functions. If an application does not
+ set ospeed, the library behaves as before, except that _nc_timed_wait
+ is no longer used, or needed, since ospeed always has a value. But
+ the application can modify ospeed to adjust the output of padding
+ characters (from a bug report for screen 3.7.6 and email from Michael
+ Schroeder <Michael.Schroeder@informatik.uni-erlangen.de>).
+ + removed some unused ifdef's as part of Alexander's restructuring.
+ + reviewed/updated curses.h, term.h against X/Open Curses Issue 4
+ Version 2. This includes making some parameters NCURSES_CONST
+ rather than const, e.g., in termcap.h.
+ + change linux terminfo entry to use ncv#2, since underline does not
+ work with color
+
+981226
+ + miscellaneous corrections for curses.h to match XSI.
+ + change --enable-no-padding configure option to be normally enabled.
+ + add section to ncurses manpage for environment variables.
+ + investigated Debian bug report that pertains to screen 3.7.4/3.7.6
+ changes, found no sign of problems on Linux (or on SunOS, Solaris)
+ running screen built with ncurses.
+ + check if tmp_fp is opened in tic.c before closing it (patch by Pavel
+ Roskin <pavel_roskin@geocities.com>).
+ + correct several font specification typos in man-pages.
+
+981220
+ + correct default value for BUILD_CC (reported by Larry Virden).
+
+981219
+ + modify _nc_set_writedir() to set a flag in _nc_tic_dir() to prevent
+ it from changing the terminfo directory after chdir'ing to it.
+ Otherwise, a relative path in $TERMINFO would confuse tic (from a
+ Debian bug report).
+ + correct/update ncsa terminfo entry (report by Larry Virden).
+ + update xterm-xfree86 terminfo to current (patch 90), smcur/rmcur changes
+ + add Mathew Vernon's mach console entries to terminfo.src
+ + more changes, moving functions, as part of Alexander's restructuring.
+ + modify configure script for GNU/Hurd share-library support, introduce
+ BUILD_CC variable for cross compiling (patch by Uchiyama Yasushi
+ <uch@nop.or.jp>)
+
+981212
+ + add environment variable NCURSES_NO_SETBUF to allow disabling the
+ setbuf feature, for testing purposes.
+ + correct ifdef's for termcap.h versus term.h that suppress redundant
+ declarations of prototypes (reported by H.J.Lu).
+ + modify Makefile.os2 to add linker flags which allow multiple copies
+ of an application to coexist (reported by Ilya Zakharevich).
+ + update Makefile.glibc and associated configure script so that ncurses
+ builds as a glibc add-on with the new directory configuration
+ (reported by H.J.Lu).
+
+981205
+ + modify gen_reps() function in gen.c to work properly on SunOS
+ (sparc), which is a left-to-right architecture.
+ + modify relative_move and tputs to avoid an interaction with the
+ BSD-style padding. The relative_move function could produce a string
+ to replace on the screen which began with a numeric character, which
+ was then interpreted by tputs as padding. Now relative_move will not
+ generate a string with a leading digit in that case (overwrite).
+ Also, tputs will only interpret padding if the string begins with a
+ digit; as coded it permitted a string to begin with a decimal point
+ or asterisk (reported by Larry Virden).
+ > patches by Juergen Pfeifer:
+ + fix a typo in m_driver.c mouse handling and improves the error
+ handling.
+ + fix broken mouse handling in the Ada95 binding
+ + make the Ada95 sample application menus work with the new menu mouse
+ support
+ + improve the mouse handling introduced by Ilya; it now handles menus
+ with spacing.
+ + repair a minor bug in the menu_driver code discovered during this
+ rework.
+ + add new function wmouse_trafo() to hide implementation details of
+ _yoffset member of WINDOW struct needed for mouse coordinate
+ transformation.
+
+981128
+ + modify Ada95/gen/gen.c to avoid using return-value of sprintf, since
+ some older implementations (e.g., SunOS 4.x) return the buffer
+ address rather than its length.
+ > patch by Rick Ohnemus:
+ + modify demo.cc to get it to compile with newer versions of egcs.
+ + trim a space that appears at the end of the table preprocessor lines
+ ('\" t). This space prevents some versions of man from displaying
+ the pages - changed to remove all trailing whitespace (TD)
+ + finally, 'make clean' does not remove panel objects.
+ > patches by Ilya Zakharevich:
+ + allow remapping of OS/2 mouse buttons using environment variable
+ MOUSE_BUTTONS_123 with the default value 132.
+ + add mouse support to ncurses menus.
+
+981121
+ + modify misc/makedef.cmd to report old-style .def file symbols, and to
+ generate the .def files sorted by increasing names rather than the
+ reverse.
+ + add misc/*.ref which are J.J.G.Ripoll's dll definition files (renamed
+ from misc/*.old), and updated based on the entrypoint coding he used
+ for an older version of ncurses.
+ + add README.emx, to document how to build on OS/2 EMX.
+ + updates for config.guess, config.sub from Lynx
+ > patches by Ilya Zakharevich:
+ + minor fixes for mouse handling mode:
+ a) Do not initialize mouse if the request is to have no mouse;
+ b) Allow switching of OS/2 VIO mouse on and off.
+ + modify Makefile.os2 to support alternative means of generating
+ configure script, by translating Unix script with Perl.
+ > patches by Juergen Pfeifer:
+ + Updates MANIFEST to reflect changes in source structure
+ + Eliminates a problem introduced with my last patch for the C++
+ binding in the panels code. It removes the update() call done in the
+ panel destructor.
+ + Changes in the Ada95 binding to better support systems where
+ sizeof(chtype)!=sizeof(int) (e.g. DEC Alpha).
+
+981114
+ + modify install-script for manpages to skip over .orig and .rej files
+ (request by Larry Virden).
+ > patches/discussion by Alexander Lukyanov:
+ + move base-library sources into ncurses/base and tty (serial terminal)
+ sources into ncurses/tty, as part of Alexander Lukyanov's proposed
+ changes to ncurses library.
+ + copy _tracemouse() into ncurses.c so that lib_tracemse.c need not
+ be linked into the normal ncurses library.
+ + move macro winch to a function, to hide details of struct ldat
+ > patches by Juergen Pfeifer:
+ + fix a potential compile problem in cursesw.cc
+ + some Ada95 cosmetics
+ + fix a gen.c problem when compiling on 64-Bit machines
+ + fix Ada95/gen/Makefile.in "-L" linker switch
+ + modify Ada95 makefiles to use the INSTALL_PREFIX setting.
+
+981107
+ + ifdef'd out lib_freeall.c when not configured.
+ + rename _tracebits() to _nc_tracebits().
+ + move terminfo-library sources into ncurses/tinfo, and trace-support
+ functions into ncurses/trace as part of Alexander Lukyanov's proposed
+ changes to ncurses library.
+ + modify generated term.h to always specify its own definitions for
+ HAVE_TERMIOS_H, etc., to guard against inclusion by programs with
+ broken configure scripts.
+
+981031
+ + modify terminfo parsing to accept octal and hexadecimal constants,
+ like Solaris.
+ + remove an autoconf 2.10 artifact from the configure script's check
+ for "-g" compiler options. (Though harmless, this confused someone
+ at Debian, who recently issued a patch that results in the opposite
+ effect).
+ + add configure option --with-ada-compiler to accommodate installations
+ that do not use gcc as the driver for GNAT (patch by Juergen
+ Pfeifer).
+
+981017
+ + ensure ./man exists in configure script, needed when configuring
+ with --srcdir option.
+ + modify infocmp "-r" option to remove limit on formatted termcap
+ output, which makes it more like Solaris' version.
+ + modify captoinfo to treat no-argument case more like Solaris' version,
+ which uses the contents of $TERMCAP as the entry to format.
+ + modify mk-2nd.awk to handle subdirectories, e.g., ncurses/tty
+ (patch by Alexander V Lukyanov).
+
+981010
+ + modify --with-terminfo-dirs option so that the default value is the
+ ${datadir} value, unless $TERMINFO_DIRS is already set. This gets
+ rid of a hardcoded list of candidate directories in the configure
+ script.
+ + add some error-checking to _nc_read_file_entry() to ensure that
+ strings are properly terminated (Todd Miller).
+ + rename manpage file curs_scr_dmp.3x to curs_scr_dump.3x, to
+ correspond with contents (reported by Neil Zanella
+ <nzanella@cs.mun.ca>).
+ + remove redundant configure check for C++ which did not work when $CXX
+ was specified with a full pathname (reported by Andreas Jaeger).
+ + corrected bcopy/memmove check; the macro was not standalone.
+
+981003
+ + remove unnecessary portion of OS/2 EMX mouse change from
+ check_pending() (reported by Alexander V Lukyanov).
+
+980926
+ + implement mouse support for OS/2 EMX (adapted from patch against
+ 4.2(?) by Ilya Zakharevich).
+ + add configure-check for bcopy/memmove, for 980919 changes to hashmap.
+ + merge Data General terminfo from Hasufin <hasufin@vidnet.net> - TD
+ + merge AIX 3.2.5 terminfo descriptions for IBM terminals, replaces
+ some older entries - TD
+ + modify tic to compile into %'char' form in preference to %{number},
+ since that is a little more efficient.
+ + minor correction to infocmp to avoid displaying "difference" between
+ two capabilities that are rendered in equivalent forms.
+ + add -g option to tic/infocmp to force character constants to be
+ displayed in quoted form. Otherwise their decimal values are shown.
+ + modify setupterm so that cancelled strings are treated the same as
+ absent strings, cancelled and absent booleans false (does not affect
+ tic, infocmp).
+ + modify tic, infocmp to discard redundant i3, r3 strings when output
+ to termcap format.
+ > patch by Alexander V Lukyanov:
+ + improve performance of tparm, now it takes 19% instead of 25% when
+ profiling worm.
+ + rename maxlen/minlen to prec/width for better readability.
+ + use format string for printing strings.
+ + use len argument correctly in save_text, and pass it to save_number.
+
+980919
+ + make test_progs compile (but hashmap does not function).
+ + correct NC_BUFFERED macro, used in lib_mvcur test-driver, modify
+ associated logic to avoid freeing the SP->_setbuf data.
+ + add modules home_terminfo and getenv_num to libtinfo.
+ + move write_entry to libtinfo, to work with termcap caching.
+ + minor fixes to blue.c to build with atac.
+ + remove softscroll.c module; no longer needed for testing.
+ > patches by Todd C Miller:
+ + use strtol(3) instead of atoi(3) when parsing env variables so we can
+ detect a bogus (non-numeric) value.
+ + check for terminal names > MAX_NAME_SIZE in a few more places when
+ dealing with env variables again.
+ + fix a MAX_NAME_SIZE that should be MAX_NAME_SIZE+1
+ + use sizeof instead of strlen(3) on PRIVATE_INFO since it is a fixed
+ string #define (compile time vs runtime).
+ + when setting errno to ENOMEM, set it right before the return, not
+ before code that could, possibly, set errno to a different value.
+ > patches by Alexander V Lukyanov:
+ + use default background in update_cost_from_blank()
+ + disable scroll-hints when hashmap is configured.
+ + improve integration of hashmap scrolling code, by adding oldhash and
+ newhash data to SP struct.
+ + invoke del_curterm from delscreen.
+ + modify del_curterm to set cur_term to null if it matches the function's
+ parameter which is deleted.
+ + modify lib_doupdate to prefer parm_ich to the enter_insert_mode and
+ exit_insert_mode combination, adjusting InsCharCost to check
+ enter_insert_mode, exit_insert_mode and insert_padding. Add
+ insert_padding in insert mode after each char. This adds new costs
+ to the SP struct.
+
+980912
+ + modify test-driver in lib_mvcur.s to use _nc_setbuffer, for consistent
+ treatment.
+ + modify ncurses to restore output to unbuffered on endwin, and resume
+ buffering in refresh (see lib_set_term.c and NC_BUFFERED macro).
+ + corrected HTML version numbers (according to the W3C validator, they
+ never were HTML 2.0-compliant, but are acceptable 3.0).
+
+980905
+ + modify MKterminfo.sh to generate terminfo.5 with tables sorted by
+ capability name, as in SVr4.
+ + modified term.h, termcap.h headers to avoid redundant declarations.
+ + change 'u_int' type in tset.c to unsigned, making this compile on
+ Sequent PRX 4.1 (reported by Michael Sterrett <msterret@coat.com>).
+
+980829
+ + corrections to mailing addresses, and moving the magic line that
+ causes the man program to invoke tbl to the first line of each
+ manpage (patch by Rick Ohnemus <rick@ecompcon.com>).
+ + add Makefile.os2 and supporting scripts to generate dll's on OS/2 EMX
+ (from J.J.G.Ripoll, with further integration by TD).
+ + correct a typo in icl6404 terminfo entry.
+ + add xtermm and xtermc terminfo entries.
+ > from esr's terminfo version:

+ + correct reversed malloc/realloc calls in _nc_doalloc (reported by
+ Hans-Joachim Widmaier <hjwidmai@foxboro.com>).
+ + correct misplaced parenthesis which caused file-descriptor from
+ opening termcap to be lost, from 980725 changes (reported by Andreas
+ Jaeger).
+
+980815
+ + modify lib_setup.c to eliminate unneeded include of <sys/ioctl.h> when
+ termios is not used (patch by Todd C Miller).
+ + add function _nc_doalloc, to ensure that failed realloc calls do not
+ leak memory (reported by Todd C Miller).
+ + improved ncsa-telnet terminfo entry.
+
+980809
+ + correct missing braces around a trace statement in read_entry.c,
+ from 980808 (reported by Kim DeVaughn <kimdv@best.com> and Liviu

+980808
+ + fix missing include <errno.h> in ditto.c (reported by Bernhard

+ + add NCSA telnet terminfo entries from Francesco Potorti
+ <F.Potorti@cnuce.cnr.it>, from Debian bug reports.
+ + make handling of $LINES and $COLUMNS variables more compatible with
+ Solaris by allowing them to individually override the window size
+ as obtained via ioctl.
+
+980801
+ + modify lib_vidattr.c to allow for terminal types (e.g., xterm-color)
+ which may reset all attributes in the 'op' capability, so that colors
+ are set before turning on bold and other attributes, but still after
+ turning attributes off.
+ + add 'ditto.c' to test directory to illustrate use of newterm for
+ initializing multiple screens.
+ + modify _nc_write_entry() to recover from failed attempt to link alias
+ for a terminfo on a filesystem which does not preserve character case
+ (reported by Peter L Jordan <PJordan@chla.usc.edu>).
+
+980725
+ + updated versions of config.guess and config.sub based on automake 1.3
+ + change name-comparisons in lib_termcap to compare no more than 2
+ characters (gleaned from Debian distribution of 1.9.9g-8.8, verified
+ with Solaris curses).
+ + fix typo in curs_insstr.3x (patch by Todd C Miller)
+ + use 'access()' to check if ncurses library should be permitted to

+ case the calling application is running in setuid mode (request by
+ Cristian Gafton <gafton@redhat.com>, responding to Duncan Simpson
+ <dps@io.stargate.co.uk>).
+ + arm100 terminfo entries from Dave Millen <dmill@globalnet.co.uk>).
+ + qnxt2 and minitel terminfo entries from esr's version.
+
+980718
+ + use -R option with ldconfig on FreeBSD because otherwise it resets
+ the search path to /usr/lib (reported by Dan Nelson).
+ + add -soname option when building shared libraries on OpenBSD 2.x
+ (request by QingLong).
+ + add configure options --with-manpage-format and --with-manpage-renames
+ (request by QingLong).
+ + correct conversion of CANCELLED_NUMERIC in write_object(), which was
+ omitting the high-order byte, producing a 254 in the compiled
+ terminfo.
+ + modify return-values of tgetflag, tgetnum, tgetstr, tigetflag,
+ tigetnum and tigetstr to be compatible with Solaris (gleaned from
+ Debian distribution of 1.9.9g-8.8).
+ + modify _nc_syserr_abort to abort only when compiled for debugging,
+ otherwise simply exit with an error.
+
+980711
+ + modify Ada95 'gen' program to use appropriate library suffix (e.g.,
+ "_g" for a debug build).
+ + update Ada95 'make clean' rule to include generics .ali files
+ + add a configure test to ensure that if GNAT is found, that it can
+ compile/link working Ada95 program.
+ + flush output in beep and flash functions, fixing a problem with
+ getstr (patch by Alexander V Lukyanov)
+ + fix egcs 1.0.2 warning for etip.h (patch by Chris Johns).
+ + correct ifdef/brace nesting in lib_sprintf.c (patch by Bernhard
+ Rosenkraenzer <bero@Pool.Informatik.RWTH-Aachen.DE>).
+ + correct typo in wattr_get macro from 980509 fixes (patch by Dan
+ Nelson).
+
+980704
+ + merge changes from current XFree86 xterm terminfo descriptions.
+ + add configure option '--without-ada'.
+ + add a smart-default for termcap 'ac' to terminfo 'acs_chars' which

+ + change translation for termcap 'rs' to terminfo 'rs2', which is
+ the documented equivalent, rather than 'rs1'.
+
+980627
+ + slow 'worm' down a little, for very fast machines.
+ + corrected firstchar/lastchar computation in lib_hline.c
+ + simplify some expressions with CHANGED_CELL, CHANGED_RANGE and
+ CHANGED_TO_EOL macros.
+ + modify init_pair so that if a color-pair is reinitialized, we will
+ repaint the areas of the screen whose color changes, like SVr4 curses
+ (reported by Christian Maurer <maurer@inf.fu-berlin.de>).
+ + modify getsyx/setsyx macros to comply with SVr4 man-page which

+
+980620
+ + review terminfo.5 against Solaris 2.6 curses version, corrected

+
+980613
+ + update man-page for for wattr_set, wattr_get (cf: 980509)
+ + correct limits in hashtest, which would cause nonprinting characters
+ to be written to large screens.
+ + correct configure script, when --without-cxx was specified: the
+ wrong variable was used for cf_cv_type_of_bool. Compilers up to gcc
+ 2.8 tolerated the missing 'int'.
+ + remove the hardcoded name "gcc" for the GNU Ada compiler. The
+ compiler's name might be something like "egcs" (patch by Juergen
+ Pfeifer).
+ + correct curs_addch.3x, which implied that echochar could directly

+ + fix typos in ncurses-intro.html (patch by Sidik Isani
+ <isani@cfht.hawaii.edu>)
+
+980606
+ + add configure test for conflicting use of exception in math.h and
+ other headers.
+ + minor optimization to 'hash()' function in hashmap.c, reduces its
+ time by 10%.
+ + correct form of LD_SHARED_OPTS for HP-UX 10.x (patch by Tim Mooney).
+ + fix missing quotes for 'print' in MKunctrl.awk script (reported by
+ Mihai Budiu <mihaib@gs41.sp.cs.cmu.edu>).
+ > patch by Alexander V Lukyanov:
+ + correct problem on Solaris (with poll() function) where getch could
+ hang indefinitely even if timeout(x) was called. This turned out to
+ be because milliseconds was not updated before 'goto retry' in
+ _nc_timed_wait.
+ + simplified the function _nc_timed_wait and fixed another bug, which
+ was the assumption of !GOOD_SELECT && HAVE_GETTIMEOFDAY in *timeleft
+ assignment.
+ + removed the cycle on EINTR, as it seems to be useless.
+
+980530
+ + add makefile-rule for test/keynames
+ + modify run_tic.sh and shlib to ensure that user's .profile does not
+ override the $PATH used to run tic (patch by Tim Mooney).
+ + restore LD_SHARED_OPTS to $(LD_SHARED_FLAGS) when linking programs,
+ needed for HP-UX shared-library path (recommended by Tim Mooney).
+ + remove special case of HP-UX -L options, use +b options to embed
+ $(libdir) in the shared libraries (recommended by Tim Mooney).
+ + add checks for some possible buffer overflows and unchecked
+ malloc/realloc/calloc/strdup return values (patch by Todd C Miller
+ <Todd.Miller@courtesan.com>)
+
+980523
+ + correct maxx/maxy expression for num_columns/num_lines in derwin
+ (patch by Alexander V Lukyanov).
+ + add /usr/share/lib/terminfo and /usr/lib/terminfo as compatibilty
+ fallbacks to _nc_read_entry(), along with --with-terminfo-dirs
+ configure option (suggested by Mike Hopkirk).
+ + modify config.guess to recognize Unixware 2.1 and 7 (patch by Mike
+ Hopkirk <hops@sco.com>).
+ + suppress definition of CC_SHARED_OPTS in LDFLAGS_SHARED in c++
+ Makefile.in, since this conflicts when g++ is used with HP-UX
+ compiler (reported by Tim Mooney).
+ + parenthesize 'strcpy' calls in c++ binding to workaround redefinition
+ in some C++ implementations (reported by several people running
+ egcs with glibc 2.0.93, analysis by Andreas Jaeger.
+
+980516
+ + modify write_entry.c so that it will not attempt to link aliases
+ with embedded '/', but give only a warning.
+ + put -L$(libdir) first when linking programs, except for HP-UX.
+ + modify comp_scan.c to handle SVr4 terminfo description for att477,
+ which contains a colon in the description field.
+ + modify configure script to support SCO osr5.0.5 shared libraries
+ (from comp.unix.sco.programmer newsgroup item by Mike Hopkirk
+ <hops@sco.com>).
+ + eliminate extra GoTo call in lib_doupdate.c (patch by Alexander V.
+ Lukyanov).
+ + minor adjustments of const/NCURSES_CONST from IRIX compile.
+ + add updates based on esr's 980509 version of terminfo.src.
+
+980509
+ + correct macros for wattr_set, wattr_get, separate wattrset macro from
+ these to preserve behavior that allows attributes to be combined with
+ color pair numbers.
+ + add configure option --enable-no-padding, to allow environment
+ variable $NCURSES_NO_PADDING to eliminate non-mandatory padding,
+ thereby making terminal emulators (e.g., for vt100) a little more
+ efficient (request by Daniel Eisenbud <eisenbud@cs.swarthmore.edu>).
+ + modify configure script to embed ABI in shared libraries for HP-UX
+ 10.x (detailed request by Tim Mooney).
+ + add test/example of the 'filter()' function.
+ + add nxterm and xterm-color terminfo description (request by Cristian
+ Gafton <gafton@redhat.com>).
+ + modify rxvt terminfo description to clear alternate screen before
+ switching back to normal screen, for compatibility with applications
+ which use xterm (reported by Manoj Kasichainula <manojk@io.com>).
+ + modify linux terminfo description to reset color palette (reported
+ by Telford Tendys <telford@eng.uts.edu.au>).
+ + correction to doupdate, for case where terminal does not support
+ insert/delete character. The logic did not check that there was a
+ difference in alignment of changes to old/new screens before
+ repainting the whole non-blank portion of the line. Modified to fall
+ through into logic that reduces by the portion which does not differ
+ (reported by Daniel Eisenbud <eisenbud@cs.swarthmore.edu>).
+ + minor performance improvement to wnoutrefresh by moving some
+ comparisons out of inner loop.
+
+980425
+ + modify configure script to substitute NCURSES_CONST in curses.h
+ + updated terminfo entries for xterm-xf86-v40, xterm-16color,
+ xterm-8bit to correspond to XFree86 3.9Ag.
+ + remove restriction that forces ncurses to use setaf/setab if the
+ number of colors is greater than 8. (see 970524 for xterm-16color).
+ + change order of -L options (so that $(libdir) is searched first) when
+ linking tic and other programs, to workaround HP's linker.
+ Otherwise, the -L../lib is embedded when linking against shared
+ libraries and the installed program does not run (reported by Ralf
+ Hildebrandt).
+ + modify configuration of shared libraries on Digital Unix so that
+ versioning is embedded in the library, rather than implied by
+ links (patch by Tim Mooney).
+
+980418
+ + modify etip.h to avoid conflict with math.h on HP-UX 9.03 with gcc
+ 2.8.1 which redefines 'exception' (reported by Ralf Hildebrandt
+ <R.Hildebrandt@tu-bs.de>).
+ + correct configure tests in CF_SHARED_OPTS which used $CC value to
+ check for gcc, rather than autoconf's $GCC value. This did not
+ work properly if the full pathname of the compiler were given
+ (reported by Michael Yount <yount@csf.Colorado.edu>).
+ + revise check for compiler options to force ANSI mode since repeating
+ an option such as -Aa causes HP's compiler to fail on its own headers
+ (reported by Clint Olsen <olsenc@ichips.intel.com>).
+
+980411
+ + ifdef'd has_key() and mcprint() as extended functions.
+ + modified several prototypes to correspond with 1997 version of
+ X/Open Curses (affects ABI since developers have used attr_get).
+ + remove spurious trailing blanks in glibc addon-scripts (patch by
+ H.J.Lu).
+ + insert a few braces at locations where gcc-2.8.x asks to use them to
+ avoid ambigous else's, use -fpic rather than -fPIC for Linux (patch
+ by Juergen Pfeifer).
+
+980404
+ + split SHLIB_LIST into SHLIB_DIRS/SHLIB_LIST to keep -L options
+ before -l to accommodate Solaris' linker (reported by Larry Virden).
+
+980328
+ + modify lib_color.c to eliminate dependency on orig_colors and
+ orig_pair, since SVr4 curses does not require these either, but
+ uses them when they are available.
+ + add detailed usage-message to infocmp.
+ + correct a typo in att6386 entry (a "%?" which was "?").
+ + add -f option to infocmp and tic, which formats the terminfo
+ if/then/else/endif so that they are readable (with newlines and
+ tabs).
+ + fixes for glibc addon scripts (patch by H.J.Lu).
+
+980321
+ + revise configure macro CF_SPEED_TYPE so that termcap.h has speed_t
+ declared (from Adam J. Richter <adam@yggdrasil.com>)
+ + remove spurious curs_set() call from leaveok() (J.T.Conklin).
+ + corrected handling leaveok() in doupdate() (patch by Alexander V.
+ Lukyanov).
+ + improved version of wredrawln (patch by Alexander V. Lukyanov).
+ + correct c++/Makefile.in so install target do not have embedded ../lib
+ to confuse it (patch by Thomas Graf <graf@essi.fr>).
+ + add warning to preinstall rule which checks if the installer would
+ overwrite a curses.h or termcap.h that is not derived from ncurses.
+ (The recommended configuration for developers who need both is to
+ use --disable-overwrite).
+ + modify preinstall rule in top-level Makefile to avoid implicit
+ use of 'sh', to accommodate Ultrix 4.4 (reported by Joao Palhoto
+ Matos <jmatos@math.ist.utl.pt>, patch by Thomas Esser
+ <te@informatik.uni-hannover.de>)
+ + refine ifdef's for TRACE so that libncurses has fewer dependencies
+ on libtinfo when TRACE is disabled.
+ + modify configure script so that if the --with-termlib option is used
+ to generate a separate terminfo library, we chain it to the ncurses
+ library with a "-l" option (reported by Darryl Miles and Ian T.
+ Zimmerman).
+
+980314
+ + correct limits and window in wredrawln function (reported/analysis by
+ Alexander V. Lukyanov).
+ + correct sed expression in configure script for --with-fallback
+ option (patch by Jesse Thilo).
+ + correct some places in configure script where $enableval was used
+ rather than $withval (patch by Darryl Miles <dlm@g7led.demon.co.uk>).
+ + modify some man-pages so no '.' or '..' falls between TH and SH
+ macros, to accommodate man_db program (reported by Ian T. Zimmerman
+ <itz@rahul.net>).
+ + terminfo.src 10.2.1 from Eric's webpage.
+ > several changes by Juergen Pfeifer:
+ + add copyright notices (and rcs id's) on remaining man-pages.
+ + corrected prototypes for slk_* functions, using chtype rather than
+ attr_t.
+ + implemented the wcolor_set() and slk_color() functions
+ + the slk_attr_{set,off,on} functions need an additional void*
+ parameter according to XSI.
+ + fix the C++ and Ada95 binding as well as the man pages to
+ reflect above enhancements.
+
+980307
+ + use 'stat()' rather than 'access()' in toe.c to check for the
+ existence of $HOME/.terminfo, since it may be a file.
+ + suppress configure CF_CXX_LIBRARY check if we are not using g++
+ 2.7.x, since this is not needed with g++ 2.8 or egcs (patch by
+ Juergen Pfeifer).
+ + turn on hashmap scrolling code by default, intend to remedy defects
+ by 4.3 release.
+ + minor corrections to terminfo.src changelog.

+ for nanosleep().
+ + moved wchgat() from lib_addch.c to lib_chgat.c

+ > adapted from patch for QNX by Xiaodan Tang:
+ + initialize %P and %g variables set/used in tparm, and also ensure
+ that empty strings don't return a null result from tparam_internal
+ + add QNX-specific prototype for vsscanf()
+ + move initialization of SP->_keytry from init_keytry() to newterm() to

+ > patches by Juergen Pfeifer:
+ + Improve a feature of the forms driver. For invisible fields
+ (O_VISIBLE off) only the contents but not the attributes are cleared.
+ We now clear both. (Reported by Javier Kohan
+ <jkohan@adan.fceia.unr.edu.ar>)
+ + The man page form_field_opts.3x makes now clear, that invisible

+ + adjust ifdef's to compile the C++ binding with the just released
+ gcc-2.8.0 c++ and the corresponding new C++ libraries.
+
+980110
+ + correct "?" command in ncurses.c; it was performing non-screen writes
+ while the program was in screen mode. (It "worked" in 1.9.9e because
+ that version sets OPOST and OCRNL incorrectly).
+ + return error from functions in lib_kernel, lib_raw and lib_ti if
+ cur_term is null, or if underlying I/O fails.
+ + amend change to tputs() so that it does not return an error if
+ cur_term is null, since some applications depend on being able to use

+ _nc_tic_expand(), for use by tack.
+ + decode \a as \007 for terminfo, as per XSI.
+ + correct translation of terminfo "^@", to \200, like \0.
+ + modify next_char() to treat <cr><lf> the same as <newline>, for

+
+971220
+ + if there's no ioctl's to support sigwinch handler, disable it.
+ + add configure option --disable-ext-funcs to remove the extended

+ + add 'sources' rule to facilitate cross-compiling.
+ + review/fix order of mostlyclean/clean/distclean rules.

+ + correct logic in _nc_remove_key(), which was discarding too many
+ nodes (patch by Alexander V. Lukyanov)
+
+971025
+ + add definition for $(REL_VERSION) to test/Makefile.in, so *BSD

+
+971011
+ + move _nc_max_click_interval and other mouse interface items to SCREEN

+971004
+ + add color, mouse support to kterm terminfo entry.
+ + modify lib_mouse.c to recognize rxvt, kterm, color_xterm also as
+ providing "xterm"-style mouse.
+ + updated rxvt's terminfo description to correspond to 2.21b, with
+ fixes for the acsc (the box1 capability is incorrect, ech1 does not
+ work).
+ + fix logic in parse_entry.c that discarded acsc when 'synthesizing'
+ an entry from equivalents in XENIX or AIX. This lets ncurses handle
+ the distribution copy of rxvt's terminfo.
+ + modify acsc capability for linux and linux-koi8 terminfo descriptions
+ (from Pavel Roskin <pavel@absolute.spb.su>).
+ + corrected definition in curses.h for ACS_LANTERN, which was 'I'
+ rather than 'i' (see 970802).
+ + updated terminfo.src with reformatted acsc entries, and repaired the
+ trashed entries with spurious '\' characters that this exposed.
+ + add logic to dump_entry.c to reformat acsc entries into canonical
+ form (sorted, unique mapping).
+ + add configure script to generate c++/etip.h
+ + add configure --with-develop option, to enable by default most of the
+ experimental options (requested by Alexander V. Lukyanov).
+ + rename 'deinstall' to 'uninstall', following GNU convention (suggested
+ by Alexander V. Lukyanov).
+ > patches by Alexander V. Lukyanov:
+ + modify tactics 2 and 5 in onscreen_mvcur(), to allow them on the last
+ line of the screen, since carriage return will not cause a newline.
+ + remove clause from PutCharLR() that would try to use
+ eat_newline_glitch since that apparently does not work on some
+ terminals (e.g., M$ telnet).
+ + correct a limit check in scroll_csr_backward()
+ > patches by Juergen Pfeifer:
+ + adds dummy implementations of methods above() and below() to the
+ NCursesPanel class.
+ + fixes missing returncode in NCursesWindow::ripoffline()
+ + fixes missing returncode in TestApplication::run() in demo.cc
+ + We should at least give a comment in etip.h why it is currently a
+ problem to install the C++ binding somewhere
+ + makes the WINDOW* argument of wenclose() a const.
+ + modifies several of the routines in lib_adabind.c to use a const
+ WINDOW* argument.
+
+970927
+ + add 'deinstall' rules.
+ + use explicit assignments in configure --without-progs option to
+ work around autoconf bug which doesn't always set $withval.
+ + check for ldconfig, don't try to run it if not found.
+ + implement simple/unoptimized case in lib_doupdate.c to handle
+ display with magic cookie glitch, tested with ncurses.c program.
+ + correct missing _tracef in getmouse(), to balance the returnCode
+ macro.
+ + simplify show_attr() in ncurses.c using termattrs().
+ > patches by Juergen Pfeifer:
+ + provides missing inlines for mvw[hv]line in cursesw.h of the C++
+ binding
+ + fixes a typo in a comment of frm_driver.c
+ + Enhances Ada95 Makefiles to fulfill the requirement of GNAT-3.10 that
+ generics should be compiled. Proper fixes to the configuration
+ scripts are also provided.
+
+970920
+ + several modifications to the configure script (requested by Ward
+ Horner):
+ + add configure options --without-progs, to suppress the build of the
+ utility programs, e.g., for cross-compiling.
+ + add $(HOSTCCFLAGS) and $(HOSTLDFLAGS) symbols to ncurses
+ Makefile.in, to simplify setup for cross compiling.
+ + add logic in configure script to recognize "--target=vxworks", and
+ generate load/install actions for VxWorks objects.
+ + move typedef for sigaction_t into SigAction.h to work around problem
+ generating lint library.
+ + modify fty_regex.c to reflect renaming of ifdef's for regular
+ expressions.
+ + simplify ifdef in lib_setup.c for TIOCGWINSZ since that symbol may
+ reside in <sys/ioctl.h>.
+ + merge testcurs.c with version from PDCurses 2.3, clarifying some of
+ the more obscure tests, which rely upon color.
+ + use macros getbegyx() and getmaxyx() in newdemo.c and testcurs.c
+ + modify ncurses.c to use getbegyx() and getmaxyx() macros to cover up
+ implementation difference wrt SVr4 curses, allow 's' test to work.
+ + add missing endwin() to testscanw.c program (reported by Fausto
+ Saporito <fausap@itb.it>).
+ + fixes/updates for Makefile.glibc and related files under sysdeps
+ (patch by H.J.Lu).
+ > patches by Juergen Pfeifer:

+ + solve a problem with wrong calculation of panel overlapping (reported
+ by Ward Horner):
+ + make sure that a panel's window isn't a pad.
+ + do more error checking in module lib_touch.c
+ + missing files for Ada95 binding from the last patch
+ + synch. of generated html pages (RCS-Id's were wrong in html files)
+ + support for Key_Resize in Ada binding
+ + changed documentation style in ./c++/cursesm.h
+ > patches by Alexander V. Lukyanov:

+ lib_doupdate.o
+
+970913
+ + modify rain.c to use color.
+ + correct scroll_csr_backward() to match scroll_csr_forward().
+ + minor adjustment to llib-lncurses, to work with Solaris 2.5.1
+ + minor fixes to sysdeps/unix/sysv/linux/configure to reflect renaming
+ of configure cache variables in 970906.
+ + correct logic involving changes to O_VISIBLE option in
+ Synchronize_Options function in frm_driver.c (Tony Hoffmann
+ <Tony.Hoffmann@hia.nrc.ca>)
+ + add $(HOSTCC) symbol to ncurses Makefile.in, to simplify setup for

+ use it to support screen-size calculation (reported by Chris Johns).
+ + #undef unctrl to avoid symbol conflict in port to RTEMS (reported by
+ Chris Johns <cjohns@plessey.com.au>)
+ > patches by Juergen Pfeifer:
+ + simplified, made minor corrections to Ada95 binding to form fieldtype.
+ + The C++ binding has been enhanced:
+ + Improve NCursesWindow class: added additional methods to cover
+ more ncurses functionality. Make refresh() and noutrefresh()
+ virtual members to allow different implementation in the
+ NCursesPanel class.
+ + CAUTION: changed order of parameters in vline() and hline() of
+ NCursesWindow class.
+ + Make refresh() in NCursesPanel non-static, it is now a
+ reimplementation of refresh() in the base class. Added
+ noutrefresh() to NCursesPanel.
+ + Added NCursesForm and related classes to support libform
+ functionality.
+ + Moved most of configuration related stuff from cursesw.h to etip.h
+ + Added NCursesApplication class to support easy configuration of
+ menu and forms related attributes as well as ripped of title lines
+ and Soft-Label-Keys for an application.
+ + Support of Auto-Cleanup for a menu's fieldlist.
+ + Change of return type for current_item() and operator[] for menus.
+ + Enhanced demo.
+ + Fixed a bug in form/fld_def.c: take into account that copyarg and
+ freearg for a fieldtype may be NULL, makearg must not be NULL
+ + Fixed a bug in form/fld_type.c: in set_fieldtype_arg() makearg must
+ not be NULL, copyarg and freearg may be NULL.
+ + Fixed a bug in form/frm_def.c: Allow Disconnect_Fields() if it is
+ already disconnected.
+ + Enhance form/frm_driver.c: Allow growth of dynamic fields also on
+ navigation requests.
+ + Fixed a bug in form/fty_enum.c: wrong position of postincrement in
+ case-insensitiva comparision routine.
+ + Enhanced form/lib_adabind.c with function _nc_get_field() to get a
+ forms field by index.
+ + Enhanced menu/m_adabind.c with function _nc_get_item() to get a menus
+ item by index.
+ + Fixed in curses.h.in: make chtype argument for pechochar() constant.
+ Mark wbkgdset() as implemented, remove wbkgdset macro, because it was
+ broken (didn't handle colors correctly).
+ + Enhanced lib_mouse.c: added _nc_has_mouse() function
+ + Added _nc_has_mouse() prototype to curses.priv.h
+ + Modified lib_bkgd.c: hopefully correct implementation of wbkgdset();
+ streamlined implementation of wbkgd()
+ + Modified lib_mvwin.c: Disable move of a pad. Implement (costly)
+ move of subwindows. Fixed update behaviour of movements of regular
+ windows.
+ + Fixed lib_pad.c: make chtype argument of pechochar() const.
+ + Fixed lib_window.c: dupwin() is not(!) in every bit a really clone
+ of the original. Subwindows become regular windows by doing a
+ dupwin().
+ + Improved manpage form_fieldtype.3x
+ > patches by Alexander V. Lukyanov:
+ + simplify the PutChar() handling of exit_am_mode, because we already
+ know that auto_right_margin is true.
+ + add a check in PutChar() for ability to insert to the case of
+ shifting character to LR corner.
+ + in terminal initialization by _nc_screen_resume(), make sure that
+ terminal right margin mode is known.
+ + move logic that invokes touchline(), or does the equivalent, into
+ _nc_scroll_window().
+ + modify scrolling logic use of insert/delete line capability, assuming
+ that they affect the screen contents only within the current
+ scrolling region.
+ + modify rain.c to demonstrate SIGWINCH handler.
+ + remove logic from getch() that would return an ERR if the application
+ called getch() when the cursor was at the lower-right corner of the
+ physical screen, and the terminal does not have insert-character
+ ability.
+ + change view.c so that it breaks out of getch() loop if a KEY_RESIZE
+ is read, and modify logic in getch() so this fix will yield the
+ desired behavior, i.e., the screen is repainted automatically when
+ the terminal window is resized.
+
+970906
+ + add configure option --enable-sigwinch
+ + modify view.c to test KEY_RESIZE logic, with "-r" option.
+ + modify testcurs.c to eliminate misleading display wrt cursor type
+ by testing if the terminal supports cnorm, civis, cvvis.
+ + several fixes for m68k/NeXT 4.0, to bring cur_term, _nc_curr_line and
+ _nc_curr_col variables into linked programs: move these variables,
+ making new modules lib_cur_term and trace_buf (reported by Francisco
+ Alberto Tomei Torres <fatomei@sandburg.unm.edu>).
+ > patches by Alexander V. Lukyanov:
+ + add pseudo-functionkey KEY_RESIZE which is returned by getch() when
+ the SIGWINCH handler has been called since the last call to
+ doupdate().
+ + modify lib_twait.c to hide EINTR only if HIDE_EINTR is defined.
+ + add SIGWINCH handler to ncurses library which is used if there is no
+ application SIGWINCH handler in effect when the screen is
+ initialized.
+ + make linked list of all SCREEN structures.
+ + move curses.h include before definition of SCREEN to use types in
+ that structure.
+ + correction to ensure that wgetstr uses only a newline to force a
+ scroll (970831).
+
+970831
+ + add experimental configure option --enable-safe-sprintf; the normal
+ mode now allocates a buffer as large as the screen for the
+ lib_printw.c functions.
+ + modify wgetch to refresh screen when reading ungetch'd characters,
+ since the application may require this - SVr4 does this.
+ + refine treatment of newline in wgetstr to echo only when this would
+ force the screen to scroll.
+
+970830
+ + remove override in wgetstr() that forces keypad(), since SVr4 does
+ not do this.
+ + correct y-reference for erasure in wgetstr() when a wrap forces a
+ scroll.
+ + correct x-position in waddch() after a wrap forces a scroll.
+ + echo newline in wgetstr(), making testscanw.c scroll properly when
+ scanw is done.
+ + modify vwscanw() to avoid potential buffer overflow.
+ + rewrote lib_printw.c to eliminate fixed-buffer limits.
+ > patches by Alexander V. Lukyanov:
+ + correct an error in handling cooked mode in wgetch(); processing
+ was in the wrong order.
+ + simplified logic in wgetch() that handles backspace, etc., by using
+ wechochar().
+ + correct wechochar() so that it interprets the output character as
+ in waddch().
+ + modify pechochar() to use prefresh() rather than doupdate(), since
+ the latter does not guarantee immediate refresh of the pad.
+ + modify pechochar() so that if called with a non-pad WINDOW, will
+ invoke wechochar() instead.
+ + modify fifo indices to allow fifo to be longer than 127 bytes.
+
+970823
+ + add xterm-8bit to terminfo.src
+ + moved logic for SP->_fifohold inside check_pending() to make it
+ work properly when we add calls to that function.
+ + ensure that bool functions return only TRUE or FALSE, and TRUE/FALSE
+ are assigned to bool values (patch by H.J.Lu).
+ > patches by Alexander V. Lukyanov:
+ + several fixes to getch:
+ 1. Separate cooked and raw keys in fifo
+ 2. Fix the case of ungetch'ed KEY_MOUSE
+ 3. wrap the code for hiding EINTR with ifdef HIDE_EINTR
+ 4. correctly handle input errors (i.e., EINTR) without loss of raw
+ keys
+ 5. recognize ESC KEY_LEFT and similar
+ 6. correctly handle the case of receiption of KEY_MOUSE from gpm
+ + correct off-by-one indexing error in _nc_mouse_parse(), that caused
+ single mouse events (press/release) to be ignored in favor of
+ composed events (click). Improves on a fix from integrating gpm
+ support in 961229.
+ + add another call to check_pending, before scrolling, for
+ line-breakout optimization
+ + improve hashmap.c by
+ 1. fixed loop condition in grow_hunks()
+ 2. not marking lines with offset 0
+ 3. fixed condition of 'too far' criteria, thus one-line hunks are
+ ignored and two lines interchanged won't pass.
+ + rewrote/simplified _nc_scroll_optimize() by separating into two
+ passes, forward/backward, looking for chunks moving only in the given
+ direction.
+ + move logic that emits sgr0 when initializing the screen to
+ _nc_screen_init(), now invoked from newterm.
+ + move cursor-movement cleanup from endwin() into _nc_mvcur_wrap()
+ function and screen cleanup (i.e., color) into _nc_screen_wrap()
+ function.
+ + add new functions _nc_screen_init(), _nc_screen_resume() and
+ _nc_screen_wrap().
+ + rename _nc_mvcur_scrolln() to _nc_scrolln().
+ + add a copy of acs_map[] to the SCREEN structure, where it can be
+ stored/retrieved via set_term().
+ + move variables _nc_idcok, _nc_idlok, _nc_windows into the SCREEN
+ structure.
+
+970816
+ + implement experimental _nc_perform_scroll().
+ + modify newterm (actually _nc_setupscreen()) to emit an sgr0 when
+ initializing the screen, as does SVr4 (reported by Alexander V.
+ Lukyanov).
+ + added test_progs rule to ncurses/Makefile.
+ + modify test/configure.in to check if initscr is already in $LIBS
+ before looking for (n)curses library.
+ + correct version-number in configure script for OSF1 shared-library
+ options (patch by Tim Mooney).
+ + add -DNDEBUG to CPPFLAGS for --enable-assertions (as Juergen
+ originally patched) since the c++ demo files do not necessarily
+ include ncurses_cfg.h
+ + supply default value for --enable-assertions option in configure
+ script (reported by Kriang Lerdsuwanakij <lerdsuwa@scf-fs.usc.edu>).
+ > patches by Alexander V. Lukyanov:
+ + correct/simplify logic of werase(), wclrtoeol() and wclrbot(). See
+ example firstlast.c
+ + optimize waddch_literal() and waddch_nosync() by factoring out
+ common subexpressions.
+ + correct sense of NDEBUG ifdef for CHECK_POSITION macro.
+ + corrections to render_char(), to make handling of colored blanks
+ match SVr4 curses, as well as to correct a bug that xor'd space
+ against the background character.
+ + replaced hash function with a faster one (timed it)
+ + rewrote the hashmap algorithm to be one-pass, this avoids multiple
+ cost_effective() calls on the same lines.
+ + modified cost_effective() so it is now slightly more precise.
+ > patches by H.J.Lu for glibc integration:
+ + add modules define_key, keyok, name_match, tries
+ + add makefile rules for some of the unit tests in ncurses (mvcur,
+ captoinfo, hardscroll, hashmap).
+ + update Linux configure-script for wide-character definitions.
+
+970809
+ + modify _tracebits() to show the character size (e.g., CS8).
+ + modify tparm() to emit '\200' where the generated string would have a
+ null (reported by From: Ian Dall <Ian.Dall@dsto.defence.gov.au> for
+ terminal type ncr7900).
+ + modify install process so that ldconfig is not invoked if the
+ package is built with an install-prefix.
+ + correct test program for chtype size (reported by Tim Mooney).
+ + add configure option --disable-scroll-hints, using this to ifdef the
+ logic that computes indices for _nc_scroll_optimize().
+ + add module ncurses/softscroll.c, to perform single-stage computation
+ of scroll indices used in _nc_scroll_optimize(). This is faster than
+ the existing scrolling algorithm, but tends to make too-small hunks.
+ + eliminate fixed buffer size in _nc_linedump().
+ + minor fixes to lib_doupdate.c to add tradeoff between clr_eol (el)
+ and clr_bol (el1), refine logic in ClrUpdate() and ClrBottom() (patch
+ by Alexander V. Lukyanov).
+ + add test/testaddch.c, from a pending patch by Alexander V. Lukyanov.
+ + correct processing of "configure --enable-assertions" option (patch
+ by Juergen Pfeifer).
+
+970802
+ + add '-s' (single-step) option too test/hashtest.c, correct an error
+ in loop limit for '-f' (footer option), toggle scrollok() when
+ writing footer to avoid wrap at lower-right corner.
+ + correct behavior of clrtoeol() immediately after wrapping cursor,
+ which was not clearing the line at the cursor position (reported by
+ Liviu Daia <daia@stoilow.imar.ro>).
+ + corrected mapping for ACS_LANTERN, which was 'I' rather than 'i'
+ (reported by Klaus Weide <kweide@tezcat.com>).
+ + many corrections to make progs/capconvert work, as well as make it
+ reasonably portable and integrated with ncurses 4.1 (reported by Dave
+ Furstenau <df@ravine.binary.net>).
+
+970726
+ + add flag SP->_fifohold, corresponding logic to modify the behavior of
+ the line breakout logic so that if the application does not read
+ input, refreshes will not be stopped, but only slowed.
+ + generate slk_attr_off(), slk_attr_on(), slk_attr_set(), vid_attr(),
+ ifdef'd for wide-character support, since ncurses' WA_xxx attribute
+ masks are identical with the A_xxx masks.
+ + modify MKlib_gen.sh to generate ifdef'd functions to support optional
+ configuration of wide-characters.
+ + modify tset to behave more like SVr4's tset, which does not modify
+ the settings of intr, quit or erase unless they are given as command
+ options (reported by Nelson H. F. Beebe <beebe@math.utah.edu>).
+ + modify tset to look in /etc/ttys or /etc/ttytype if the configuration
+ does not have getttynam().
+ + extend baudrate table in tset.c to match baudrate() function.
+ + add table entries for 230400 and 460800 bd to baudrate() function.
+ + improve breakout logic by allowing it before the first line updated,
+ which is what SVr4 curses does (patch by Alexander V. Lukyanov).
+ + correct initialization of vcost in relative_move(), for cursor-down
+ case (patch by Alexander V. Lukyanov).
+ > nits gleaned from Debian distribution of 1.9.9g-3:
+ + install symbolic link for intotocap.
+ + reference libc directly when making shared libraries.
+ + correct renaming of curs_scr_dmp.3x in man_db.renames.
+ + guard tgetflag() and other termcap functions against null cur_term
+ pointer.
+
+970719
+ + corrected initial state of software echo (error in 970405, reported
+ by Alexander V. Lukyanov).
+ + reviewed/added messages to configure script, so that all non-test
+ options should be accompanied by a message.
+ + add configure check for long filenames, using this to determine if
+ it is safe to allow long aliases for terminal descriptions as does
+ SVr4.
+ + add configure options for widec (wide character), hashmap (both
+ experimental).
+ > patch by Alexander V. Lukyanov:
+ + hashmap.c - improved by heuristic, so that scroll test works much
+ better when csr is not available.
+ + hardscroll.c - patched so that it continues to scroll other chunks
+ after failure to scroll one.
+ + lib_doupdate.c - _nc_mvcur_scrolln extended to handle more cases; csr
+ is avoided as it is relative costly. Fixed wrong coordinates in one
+ case and wrong string in TRACE.
+ > patch by Juergen Pfeifer:
+ + modify C++ binding to compile on AIX 4.x with the IBM C-SET++
+ compiler.
+
+970712
+ + remove alternate character set from kterm terminfo entry; it uses the
+ shift-out control for a purpose incompatible with curses, i.e., font
+ switching.
+ + disentangle 'xterm' terminfo entry from some derived entries that
+ should be based on xterm-r6 instead.
+ + add cbt to xterm-xf86-xv32 terminfo entry; I added the emulation for
+ XFree86 3.1.2F, but overlooked its use in terminfo then - T.Dickey.
+ + correct logic in lib_mvcur.c that uses back_tab.
+
+970706
+ + correct change from 970628 to ClrUpdate() in lib_doupdate.c so that
+ contents of curscr are saved in newscr before clearing the screen.
+ This is needed to make repainting work with the present logic of
+ TransformLine().
+ + use napms() rather than sleep() in tset.c to avoid interrupting I/O.
+
+970705
+ + add limit checks to _nc_read_file_entry() to guard against overflow
+ of buffer when reading incompatible terminfo format, e.g, from OSF/1.
+ + correct some loop-variable errors in xmc support in lib_doupdate.c
+ + modify ncurses 'b' test to add gaps, specified by user, to allow
+ investigation of interaction with xmc (magic cookie) code.
+ + correct typo in 970524 mods to xmas.c, had omitted empty parameter
+ list from has_colors(), which gcc ignores, but SVr4 does not
+ (reported by Larry Virden).
+ + correct rmso capability in wy50-mc description.
+ + add configure option "--enable-hard-tabs", renamed TABS_OK ifdef to
+ USE_HARD_TABS.
+ > patch by Juergen Pfeifer:
+ + Add bindings for keyok() and define_key() to the Ada95 packages.
+ + Improve man pages menu_post.3x and menu_format.3x
+ + Fix the HTML pages in the Ada95/html directory to reflect the above
+ changes.
+
+970628
+ + modify change from 970101 to ClrUpdate() in lib_doupdate.c so that
+ pending changes to both curscr and newscr are flushed properly.
+ This fixes a case where the first scrolling operation in nvi would
+ cause the screen to be cleared unnecessarily and repainted before
+ doing the indexing, i.e., by repeatedly pressing 'j' (reported by
+ Juergen Pfeifer).
+ + correct error in trans_string() which added embedded newlines in a
+ terminfo description to the stored strings.
+ + remove spurious newlines from sgr in wyse50 (and several other)
+ terminfo descriptions.
+ + add configure option for experimental xmc (magic cookie) code,
+ "--enable-xmc-glitch". When disabled (the default), attributes that
+ would store a magic cookie are suppressed in vidputs(). The magic
+ cookie code is far from workable at this stage; the configuration
+ option is a stopgap.
+ + move _nc_initscr() from lib_initscr.c to lib_newterm.c
+ + correct path for invoking make_keys (a missing "./").
+
+970621
+ + correct sign-extension problem with "infocmp -e", which corrupted
+ acsc values computed for linux fallback data.
+ + correct dependency on ncurses/names.c (a missing "./").
+ + modify configure script to use '&&' even for cd'ing to existing
+ directories to work around broken shell interpreters.
+ + correct a loop-limit in _nc_hash_map() (patch by Alexander V.
+ Lukyanov).
+
+970615
+ + restore logic in _nc_scroll_optimize() which marks as touched the
+ lines in curscr that are shifted.
+ + add new utility 'make_keys' to compute keys.tries as a table rather
+ than a series of function calls.
+ + correct include-dependency for tic.h used by name_match
+ + removed buffer-allocation for name and description from m_item_new.c,
+ since this might result in incompatibilities with SVr4. Also fixed
+ the corresponding Ada95 binding module (patch by Juergen Pfeifer,
+ from report by Avery Pennarun <apenwarr@foxnet.net>)
+ + removed the mechanism to timestamp the generated Ada95 sources. This
+ resulted always in generating patches for the HTML doc, even when
+ nothing really changed (patch by Juergen Pfeifer).
+ + improve man page mitem_new.3x (patch by Juergen Pfeifer).
+
+970614
+ + remove ech capability from rxvt description because it does not work.
+ + add missing case logic for infocmp -I option (reported by Lorenzo M.
+ Catucci <lorenzo@argon.roma2.infn.it>)
+ + correct old bug in pnoutrefresh() unmasked by fix in 970531; this
+ caused glitches in the ncurses 'p' test since the area outside the
+ pad was not compared when setting up indices for _nc_scroll_optimize.
+ + rewrote tracebits() to workaround misdefinition of TOSTOP on Ultrix
+ 4.4, as well as to eliminate fixed-size buffer (reported by Chris
+ Tanner <tannerc@aecl.ca>)
+ + correct prototype for termattrs() as per XPG4 version 2.
+ + add placeholder prototypes for color_set(), erasewchar(),
+ term_attrs(), wcolor_set() as per XPG4 version 2.
+ + correct attribution for progs/progs.priv.h and lib_twait.c
+ + improve line-breakout logic by checking based on changed lines rather
+ than total lines (patch by Alexander V. Lukyanov).
+ + correct loop limits for table-lookup of enumerated value in form
+ (patch by Juergen Pfeifer).
+ + improve threshhold computation for determining when to call ClrToEOL
+ (patch by Alexander V. Lukyanov).
+
+970531
+ + add configure option --disable-database to force the library to
+ use only the fallback data.
+ + add configure option --with-fallbacks, to specify list of fallback
+ terminal descriptions.
+ + add a symbolic link for ncurses.h during install; too many programs
+ still assume there's an ncurses.h
+ + add new terminfo.src entry for xterm-xf86-v33.
+ + restore terminfo.src entry for emu to using setf/setb, since it is
+ not, after all, generating ANSI sequences. Corrected missing comma
+ that caused setf/setb entries to merge.
+ + modify mousemask() to use keyok() to enable/disable KEY_MOUSE, so
+ that applications can disable ncurses' mouse and supply their own
+ handler.
+ + add extensions keyok() and define_key(). These are designed to allow
+ the user's application better control over the use of function keys,
+ e.g., disabling the ncurses KEY_MOUSE. (The define_key idea was from
+ a mailing-list thread started by kjahds@kjahds.com Nov'1995).
+ + restore original behavior in ncurses 'g' test, i.e., explicitly
+ set the keypad mode rather than use the default, since it confuses
+ people.
+ + rewrote the newdemo banner so it's readable (reported by Hugh Daniel).
+ + tidy up exit from hashtest (reported by Hugh Daniel).
+ + restore check for ^Q in ncurses 'g' test broken in 970510 (reported
+ by Hugh Daniel)
+ + correct tput program, checking return-value of setupterm (patch by
+ Florian La Roche).
+ + correct logic in pnoutrefresh() and pechochar() functions (reported
+ by Kriang Lerdsuwanakij <lerdsuwa@scf.usc.edu>). The computation
+ of 'wide' date to eric's #283 (1.9.9), and the pechochar bug to the
+ original implementation (1.9.6).
+ + correct typo in vt102-w terminfo.src entry (patch by Robert Wuest
+ <rwuest@sire.vt.com>)
+ + move calls of _nc_background() out of various loops, as its return
+ value will be the same for the whole window being operated on (patch
+ by J.T.Conklin).
+ + add macros getcur[xy] getbeg[xy] getpar[xy], which are defined in
+ SVr4 headers (patch by J.T.Conklin <jtc@NetBSD.ORG>)
+ + modify glibc addon-configure scripts (patch by H.J.Lu).
+ + correct a bug in hashmap.c: the size used for clearing the hashmap
+ table was incorrect, causing stack corruption for large values of
+ LINES, e.g., >MAXLINES/2 (patch by Alexander V. Lukyanov).
+ + eric's terminfo 9.13.23 & 9.13.24 changes: replaced minitel-2 entry,
+ added MGR, ansi-nt (note: the changes described for 9.13.24 have not
+ been applied).
+ > several changes by Juergen Pfeifer:
+ + correct a missing error-return in form_driver.c when wrapping of a
+ field is not possible.
+ + correct logic in form_driver.c for configurations that do not have
+ memccpy() (reported by Sidik Isani <isani@cfht.hawaii.edu>)
+ + change several c++ binding functions to inline.
+ + modify c++ menu binding to inherit from panels, for proper
+ initialization.
+ + correct freeing of menu items in c++ binding.
+ + modify c++ binding to reflect removal of const from user data pointer
+ in forms/menus libraries.
+
+970524
+ + add description of xterm-16color.
+ + modify name of shared-library on *BSD to end with $(REL_VERSION)
+ rather than $(ABI_VERSION) to match actual convention on FreeBSD
+ (cf: 960713).
+ + add OpenBSD to shared-library case, same as NetBSD and FreeBSD
+ (reported by Hugh Daniel <hugh@rat.toad.com>).
+ + corrected include-dependency in menu/Makefile so that "make install"
+ works properly w/o first doing "make".
+ + add fallback definition for isascii, used in infocmp.
+ + modify xmas to use color, and to exit right away when a key is
+ pressed.
+ + modify gdc so that the scrolled digits function as described (there
+ was no time delay between the stages, and the digits overwrote the
+ bounding box without tidying up).
+ + modify lib_color.c to use setaf/setab only for the ANSI color codes
+ 0 through 7. Using 16 colors requires setf/setb.
+ + modify ncurses 'c' test to work with 16 colors, as well as the normal
+ 8 colors.
+ + remove const qualifier from user data pointer in forms and menus
+ libraries (patch by Juergen Pfeifer).
+ + rewrote 'waddchnstr()' to avoid using the _nc_waddch_nosync()
+ function, thereby not interpreting tabs, etc., as per spec (patch by
+ Alexander V. Lukyanov).
+
+970517
+ + suppress check for pre-existing ncurses header if the --prefix
+ option is specified.
+ + add configure options "--with-system-type" and "--with-system-release"
+ to assist in checking the generated makefiles.
+ + add configure option "--enable-rpath" to allow installers to specify
+ that programs linked against shared libraries will have their library
+ path embedded, allowing installs into nonstandard locations.
+ + add flags to OSF1 shared-library options to specify version and
+ symbol file (patch by Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu>)
+ + add missing definition for ABI_VERSION to c++/Makefile.in (reported
+ by Satoshi Adachi <adachi@wisdom.aa.ap.titech.ac.jp>).
+ + modify link flags to accommodate HP-UX linker which embeds absolute
+ pathnames in executables linked against shared libraries (reported by
+ Jason Evans <jasone@mrc.uidaho.edu>, solved by Alan Shutko
+ <ats@hubert.wustl.edu>).
+ + drop unnecessary check for attribute-change in onscreen_mvcur() since
+ mvcur() is the only caller within the library, and that check in turn
+ is exercised only from lib_doupdate.c (patch by Alexander V.
+ Lukyanov).
+ + add 'blank' parameter to _nc_scroll_window() so _nc_mvcur_scrolln()
+ can use the background of stdscr as a parameter to that function
+ (patch by Alexander V. Lukyanov).
+ + moved _nc_mvcur_scrolln() from lib_mvcur.c to lib_doupdate.c, to use
+ the latter's internal functions, as well as to eliminate unnecessary
+ cursor save/restore operations (patch by Alexander V. Lukyanov).
+ + omit parameter of ClrUpdate(), since it is called only for newscr,
+ further optimized/reduced by using ClearScreen() and TransformLine()
+ to get rid of duplicate code (patch by Alexander V. Lukyanov).
+ + modify scrolling algorithm in _nc_scroll_optimize() to reject hunks
+ that are smaller than the distance to be moved (patch by Alexander V.
+ Lukyanov).
+ + correct a place where the panel library was not ifdef'd in ncurses.c
+ (Juergen Pfeifer)
+ + documentation fixes (Juergen Pfeifer)
970515 4.1 release for upload to prep.ai.mit.edu
+ re-tag changes since 970505 as 4.1 release.
rather than the strings which they (may) point to.
+ add check to ensure that C++ binding and demo are not built with g++
versions below 2.7, since the binding uses templates.
- + modify c++ binding and demo to build and run with SGI's c++ compiler.
+ + modify c++ binding and demo to build and run with SGI's c++ compiler.
(It also compiles with the Sun SparcWorks compiler, but the demo does
not link, due to a vtbl problem).
+ corrections to demo.cc, to fix out-of-scope variables (Juergen
+ add header dependencies so that "make install.libs" will succeed
even if "make all" is not done first.
+ moved some macros from lib_doupdate.c to curses.priv.h to use in
- expanded functions with ATAC.
+ expanded functions with ATAC.
+ correct implementation of lib_instr.c; both XSI and SVr4 agree that
the winnstr functions can return more characters than will fit on one
line.
> contrary to comments, some scrolling cases were tested after the
insert/delete line method.
+ modify _tracedump() to show first/last changes.
- + modify param of ClrUpdate() in lib_doupdate.c to 'curscr', fixes
+ + modify param of ClrUpdate() in lib_doupdate.c to 'newscr', fixes
refresh problem (reported by Peter Wemm) that caused nvi to not show
result of ":r !ls" until a ^L was typed.
