- * correct manlinks.sed script introduced in ncurses 5.1 to avoid
- using ERE "\+", which is not understood by standard versions of
- sed. This happens to work with GNU sed, but is not portable, and
- was the initial motivation for this release.
- * remove "hpux10.*" case from CF_SHARED_OPTS configure script macro.
- This differed from the "hpux*" case by using reversed symbolic
- links, which made the 5.1 version not match the configuration of
- 5.0 shared libraries.
- * guard against corrupt terminfo data:
- + modify tparm() to disallow arithmetic on strings, analyze the
- varargs list to read strings as strings and numbers as
- numbers.
- + modify tparm()'s internal function spop() to treat a null
- pointer as an empty string.
- + modify parse_format() in lib_tparm.c to ignore precision if
- it is longer than 10000.
- + rewrote limit checks in lib_mvcur.c using new functions
- _nc_safe_strcat(), etc. Made other related changes to check
- lengths used for strcat() and strcpy().
- * corrections to screen optimization:
- + added special case in lib_vidattr.c to reset underline and
- standout for devices that have no sgr0 defined.
- + change handling of non_dest_scroll_region in tty_update.c to
- clear text after it is shifted in rather than before shifting
- out. Also correct row computation.
- + modify rs2 capability in xterm-r6 and similar entries where
- cursor save/restore bracketed the sequence for resetting
- video attributes. The cursor restore would undo that.
- * UTF-8 support:
- + when checking LC_ALL, LC_CTYPE, and LANG environment
- variables for UTF-8 locale, ignore those which are set to an
- empty value, as per SUSV2.
- + encode 0xFFFD in UTF-8 with 3 bytes, not 2.
- + modify _nc_utf8_outch() to avoid sign-extension when checking
- for out-of-range value.
- * other library fixes:
- + added checks for an empty $HOME environment variable, to
- avoid retrieving terminfo descriptions from ./.terminfo .
- + change functions _nc_parse_entry() and postprocess_termcap()
- to avoid using strtok(), because it is non-reentrant.
- + initialize fds[] array to 0's in _nc_timed_wait(); apparently
- poll() only sets the revents members of that array when there
- is activity corresponding to the related file.
- + add a check for null pointer in Make_Enum_Type().
- + fix a heap problem with the c++ binding.
- + correct missing includes for <string.h> in several places,
- including the C++ binding. This is not noted by gcc unless we
- use the -fno-builtin option.
- * several fixes for tic:
- + add a check for empty buffers returned by fgets() in
- comp_scan.c next_char() function, in case tic is run on a
- non-text file (fixes a core dump).
- + modify tic to verify that its inputs are really files, in
- case someone tries to read a directory (or /dev/zero).
- + correct an uninitialized parameter to open_tempfile() in
- tic.c which made "tic -I" give an ambiguous error message
- about tmpnam.
- + correct logic in adjust_cancels(), which did not check both
- alternatives when reclassifying an extended name between
- boolean, number and string, causing an infinite loop in tic.
- * using new checks in tic for parameter counts in capability
- strings, found/fixed several errors both in the terminfo database
- and in the include/Caps file.
- + modified several terminfo capability strings, including the
- definitions for setaf, setab, in include/Caps to indicate
- that the entries are parameterized. This information is used
- to tell which strings are translated when converting to
- termcap. This fixes a problem where the generated termcap
- would contain a spurious "%p1" for the terminfo "%p1%d".
- + correct parameter counts in include/Caps for dclk as well as
- some printer-specific capabilities: csnm, defc, scs, scsd,
- smgtp, smglp.
- * various fixes for install scripts used to support configure
- --srcdir and --with-install-prefix.
- * correct several mismatches between manpage filename and ".TH"
- directives, renaming dft_fgbg.3x to default_colors.3x and
- menu_attribs.3x to menu_attributes.3x.
+ * rewrote limit-checks in wscrl() and associated
+ _nc_scroll_window(), to ensure that if the parameter of wscrl() is
+ larger than the size of the scrolling region, then the scrolling
+ region will be cleared.
+ * modify tset to restore original I/O modes if an error is
+ encountered. Also modify to use buffered stderr consistently
+ rather than mixing with write().
+ * move calls to def_shell_mode() and def_prog_mode() before loop
+ with callbacks in lib_set_term.c, since the c++ demo otherwise
+ initialized the tty modes before saving them.
+ * modified wresize() to ensure that a failed realloc will not
+ corrupt the window structure, and to make subwindows fit within
+ the resized window.
+ * altered resizeterm() to avoid having it fail when a child window
+ cannot be resized because it would be larger than its parent.
+ * correct/improve logic to produce an exit status for errors in
+ tput, which did not exit with an error when told to put a string
+ not in the current terminfo entry.
+ * modify behavior of can_clear_with() so that if an application is
+ running in a non-bce terminals with default colors enabled, it
+ returns true, allowing the user to select/paste text without
+ picking up extraneous trailing blanks.
+ * add a check in relative_move() to guard against buffer overflow in
+ the overwrite logic.
+ * add some limit/pointer checks to -S option of tputs.
+ * modify mvcur() to avoid emitting newline characters when nonl()
+ mode is set. Normally this is not a problem since the actual
+ terminal mode is set to suppress nl/crlf translations, however it
+ is useful to allow the caller to manipulate the terminal mode to
+ avoid staircasing effects after spawning a process which writes
+ messages (for lynx 2.8.4).
