| * Fix unoptimized build on MSDOS.Eli Zaretskii2014-08-251-0/+4
| | | | | | | | | | | | | | msdos/sedlibmk.inp (gl_LIBOBJS): Add execinfo.o. Reported by Juan Manuel Guerrero <juan.guerrero@gmx.de>. src/conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Don't define.
| * src/xdisp.c (handle_stop): Improve commentary.Eli Zaretskii2014-08-181-0/+2

| * Fix bug #18276 with vertical motion through a display property.Eli Zaretskii2014-08-181-0/+5
| | | | | | | | | | src/indent.c (Fvertical_motion): Fix vertical motion up through a display property after a newline.
| * Avoid inflooping in redisplay caused by hscrolled R2L lines.Eli Zaretskii2014-08-171-0/+7
| | | | | | | | | | | | | | | | | | src/xdisp.c (display_line): Don't assume that the call to reseat_at_next_visible_line_start ends up at a character immediately following the newline on the previous line. Avoids setting the ends_at_zv_p flag on screen lines that are not at or beyond ZV, which causes infloop in redisplay. For the details, see http://lists.gnu.org/archive/html/emacs-devel/2014-08/msg00368.html.
| * Fix bug #18277 with mouse clicks on R2L lines.Eli Zaretskii2014-08-171-0/+5
| | | | | | | | | | src/dispnew.c (buffer_posn_from_coords): Fix mirroring of X coordinate for hscrolled R2L screen lines.
* | * sysdep.c (LC_COLLATE, LC_COLLATE_MASK): Give individual defaults.Paul Eggert2014-08-271-0/+5
| | | | | | | | Fixes: debbugs:18051
* | Fix bug #18339 with segfault when $ is typed into empty LaTeX buffer.Eli Zaretskii2014-08-271-0/+5
| | | | | | | | src/syntax.c (scan_lists): Don't examine positions before BEGV.
* | Improve robustness of new string-collation code.Paul Eggert2014-08-271-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * configure.ac (newlocale): Check for this, not for uselocale. * src/sysdep.c (LC_COLLATE, LC_COLLATE_MASK, freelocale, locale_t) (newlocale, wcscoll_l): Define substitutes for platforms that lack them, so as to simplify the mainline code. (str_collate): Simplify the code by assuming the above definitions. Use wcscoll_l, not uselocale, as uselocale is too fragile. For example, the old version left the Emacs in the wrong locale if wcscoll reported an error. Use 'int', not ptrdiff_t, for the int result. Report an error if newlocale fails. Fixes: debbugs:18051
* | * lisp.h (str_collate):Michael Albinus2014-08-271-0/+6
| | | | | | | | | | * sysdep.c (str_collate): Return int. (str_collate) [__STDC_ISO_10646__]: Propagate error of wcscoll.

* | Fix some glitches in previous change.Dmitry Antipov2014-08-271-0/+9
| | | | | | | | | | | | | | | | * sysdep.c (stack_direction): Replace stack_grows_down to simplify calculation of stack boundaries. (handle_sigsegv): Check whether we really crash somewhere near to stack boundary, and handle fatal signal as usual if not. (init_sigsegv): Adjust accordingly.
* | ChangeLog fixesGlenn Morris2014-08-261-3/+4

* | Handle C stack overflow caused by too nested Lisp evaluation.Dmitry Antipov2014-08-261-0/+19

(stack_grows_down, sigsegv_stack, handle_sigsegv) [HAVE_STACK_OVERFLOW_HANDLING]: New variables and function. (init_sigsegv): New function. (init_signals): Use it. * lisp/startup.el (normal-top-level): Use top-level-message.

| | | | | | | | | | * src/emacs.c (main): Remove use of obsolete macro G_SLICE_ALWAYS_MALLOC.
* | Implement locale-sensitive string collation for MS-Windows. (Bug#18051)Eli Zaretskii2014-08-251-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | src/w32proc.c (get_lcid_callback, get_lcid, w32_compare_strings): New functions. src/w32.h (w32_compare_strings): Add prototype. src/w32.c <g_b_init_compare_string_w>: New global flag.

| | | | | | | | | | | | | | | | | | | | | | * font.h (struct font_driver): Convert text_extents to return void because returned value is never actually used. * macfont.c (macfont_text_extents): * w32font.c (w32font_text_extents): * xftfont.c (xftfont_text_extents): Adjust to return void and assume that 'metrics' argument is always non-NULL. * ftfont.c (ftfont_text_extents): * xfont.c (xfont_text_extents): Likewise.

* | Minor cleanups of str_collate fix.Paul Eggert2014-08-241-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | * fns.c (str_collate): Move decl from here ... * lisp.h (str_collate): ... to here. * sysdep.c (str_collate): Prune away some of the forest of ifdefs. Remove unnecessary casts. Use SAFE_NALLOCA to avoid potential problems with integer overflow. Don't assume setlocale succeeds. Remove unnecessary test before restoring locale via setlocale, and free the copied setlocale string when done with it. Fixes: debbugs:18051

| | | | | | | | | | | | | | | | * configure.ac: Check also for the uselocale function. * src/fns.c (Fstring_collate_lessp, Fstring_collate_equalp): New DEFUNs. * src/sysdep.c (str_collate): New function. (Bug#18051)

| | | | | | | | | | | | | | | | | | | | | | configure.ac: Accept "*-mingw*", not just "*-mingw32", as canonical name of a MinGW build, because using MSYS2 'uname' produces "MINGW64". src/Makefile.in (emacs$(EXEEXT)): Retry deletion of bootstrap-emacs if the initial "rm -f" fails. This is for MinGW builds, where MS-Windows will not allow deleting the executable file of a running program.

* | Fix horizontal scroll bar dragging in R2L paragraphs.Eli Zaretskii2014-08-191-0/+6
| | | | | | | | | | | | src/w32term.c (w32_horizontal_scroll_bar_handle_click): Fix the second coordinate ('y') reported for dragging the horizontal scroll bar thumb.
* | * xdisp.c (erase_phys_cursor): Fix confusion between window-relativeYAMAMOTO Mitsuharu2014-08-191-0/+5
| | | | | | | | and text area-relative x-coordinates.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It causes a more serious problem than the one it solves.
