Major bug fixes: - * prevent recursion in wgetch() via wgetnstr() if the connection - cannot be switched between cooked/raw modes because it is not a - TTY. - * correct a case in _nc_remove_string(), used by define_key(), to - avoid infinite loop if the given string happens to be a substring - of other strings which are assigned to keys. - * modify logic of acsc to use the original character if no mapping - is defined, rather than a null. - * several improvements for handling multi-cell display of wide - characters. - + modify setcchar() to allow converting control characters to - complex characters. - + correct handling of multibyte characters in waddch_literal() - which force wrapping because they are started too late on the - line. - + modify setcchar() to allow for wchar_t input strings that - have more than one spacing character. - * other fixes for wide-character support: - + rewrote lib_acs.c to allow PutAttrChar() to decide how to - render alternate-characters, i.e., to work with Linux console - and UTF-8 locale. - + implement a workaround so that line-drawing works with - screen's crippled UTF-8 support (tested with 3.9.13). This - only works with the wide-character support (--enable-widec); - the normal library will simply suppress line-drawing when - running in a UTF-8 locale in screen. - + corrections to lib_get_wstr.c: - o null-terminate buffer passed to setcchar(), which - occasionally failed. - o map special characters such as erase- and - kill-characters into key-codes so those will work as - expected even if they are not mentioned in the terminfo. - * modify setupterm() to check if the terminfo and terminal-modes - have already been read. This ensures that it does not reinvoke - def_prog_mode() when an application calls more than one function, - such as tgetent() and initscr(). - * fix form_driver() cases for REQ_CLR_EOF, REQ_CLR_EOL, - REQ_DEL_CHAR, REQ_DEL_PREV and REQ_NEW_LINE, which did not ensure - the cursor was at the editing position before making - modifications. - * correct keybound(), which reported definitions in the wrong table, - i.e., the list of definitions which are disabled by keyok(). - * fixes related to safe_sprintf.c: - + correct an allocation size in safe_sprintf.c for the "*" - format code. - + correct safe_sprintf.c to not return a null pointer if the - format happens to be an empty string. - + make return value from _nc_printf_string() consistent. - Before, depending on whether --enable-safe-sprintf was used, - it might not be cached for reallocating. - * other low-level improvements to the optimization code include: - + if the output is a socket or other non-tty device, use 1 - millisecond for the cost in mvcur; previously it was 9 - milliseconds because the baudrate was not known. - + modify lib_getch.c to avoid recursion via wgetnstr() when the - input is not a tty and consequently mode-changes do not work. - + fix several places in tack/pad.c which tested and used the - parameter- and parameterless strings inconsistently. - + change several tputs() calls in scrolling code to use putp(), - to enable padding which may be needed for some terminals. - + improve mvcur() by checking if it is safe to move when video - attributes are set (msgr), and if not, reset/restore - attributes within that function rather than doing it - separately in the GoTo() function in tty_update.c. - + use tputs() rather than putp() in a few cases in tty_update.c - since the corresponding delays are proportional to the number - of lines affected: repeat_char, clr_eos, - change_scroll_region. - * correct line/column reference in adjust_window(), needed to make - special windows such as curscr track properly when resizing. - * fix a potential recursion between napms() and _nc_timed_wait() - * rewrote lib_insch.c, combining it with lib_insstr.c so both handle - tab and other control characters consistently. - * do not try to open gpm mouse driver if standard output is not a - tty; the gpm library does not make this check. + * add logic to tic for cancelling strings in user-defined + capabilities (this is needed for current konsole terminfo entry). + * modify mk-1st.awk so the generated makefile rules for linking or + installing shared libraries do not first remove the library, in + case it is in use, e.g., libncurses.so by /bin/sh. + * correct check for notimeout() in wgetch(). + * fix a sign-extension bug in infocmp's repair_acsc() function. + * change winnstr() to stop at the end of the line. + * make Ada95 demo_panels() example work. + * fix for adding a non-spacing character at the beginning of a line. + * fill in extended-color pair to make colors work for + wide-characters using extended-colors. + * improve refresh of window on top of multi-column characters, + taking into account split characters on left/right window + boundaries. + * modify win_wchnstr() to ensure that only a base cell is returned + for each multi-column character. + * improve waddch() and winsch() handling of EILSEQ from mbrtowc() by + using unctrl() to display illegal bytes rather than trying to + append further bytes to make up a valid sequence. + * restore curs_set() state after endwin()/refresh() + * modify keyname() to use "^X" form only if meta() has been called, + or if keyname() is called without initializing curses, e.g., via + initscr() or newterm(). + * modify unctrl() to check codes in 128-255 range versus isprint(). + If they are not printable, and locale was set, use a "M-" or "~" + sequence. + * improve resizeterm() by moving ripped-off lines, and repainting + the soft-keys. + * modify form library to accept control characters such as newline + in set_field_buffer(), which is compatible with Solaris. + * use NCURSES_MOUSE_MASK() in definition of BUTTON_RELEASE(), etc., + to make those work properly with the --enable-ext-mouse + configuration + * correct some functions in Ada95 binding which were using return + value from C where none was returned. + * reviewed/fixed issues reported by Coverity and Klocwork tools. Portability: * configure script: + new options: - --with-abi-version option. - addresses platforms where packagers have diverged - from ncurses ABI numbering. - - --with-manpage-format=catonly - addresses behavior of BSDI, allow install of - man+cat files on NetBSD, whose behavior has - diverged by requiring both to be present. - - --with-manpage-aliases - extends "--with-manpage-aliases" to provide the - option of generating ".so" files rather than - symbolic links for manpage aliases. - - --with-rel-version - workaround to force libtool on Darwin generate the - "same" library names as with the "--with-shared" - option. The Darwin ld program does not work well - with a zero as the minor-version value. - - --with-trace - simplifies defining TRACE to incorporate trace() in - libraries. - - + fixes/improvements for cross-compiling: - o allow BUILD_CC and related configure script variables to - be overridden from the environment. - o use AC_CHECK_TOOL to get proper values for AR and LD for - cross compiling. - o use $cross_compiling variable in configure script rather - than comparing $host_alias and $target alias, since - "host" is traditionally misused in autoconf to refer to - the target platform. - o modify run_tic.in to avoid using wrong shared libraries - when cross-compiling. - + fixes for Mac OS X: - o fix a redefinition of $RANLIB in the configure script - when libtool is used. - o modify MKlib_gen.sh to avoid passing "#" tokens through - the C preprocessor. This works around Mac OS X's - preprocessor, which insists on adding a blank on each - side of the token. - + workarounds for broken tools: - o add configure check for wchar_t and wint_t types, rather - than rely on preprocessor definitions. Also work around - for gcc fixinclude bug which creates a shadow copy of - curses.h if it sees these symbols apparently typedef'd. - o modify configure script to omit -Winline for gcc 3.3, - since that feature is broken. - o several script fixes to work around the ironically named - POSIXLY_CORRECT feature of GNU sed 4.0. - o modify configure script to avoid using "head -1", which - does not work if POSIXLY_CORRECT (sic) is set. - o update configure script to reflect fix for - AC_PROG_GCC_TRADITIONAL, which is broken in autoconf - 2.5x for Mac OS X 10.2.3. - o repair check for missing C++ compiler, which is broken - in autoconf 2.5x by hardcoding it to g++. - + corrected ifdef's relating to configure check for wchar_t, - etc. - + remove configure script check to allow -Wconversion for older - versions of gcc - + modify configure script to accommodate libtool 1.5, as well - as add an parameter to the "--with-libtool" option which can - specify the pathname of libtool. - + change several sed scripts to avoid using "\+" since it is - not a BRE (basic regular expression).
