Instead of using gnutls_global_set_mem_functions, check every call
to a GnuTLS function that might return an indication of memory
exhaustion. Suggested by Dmitry Antipov in:
http://lists.gnu.org/archive/html/emacs-devel/2014-12/msg02056.html
* src/gnutls.c (gnutls_global_set_mem_functions) [WINDOWSNT]: Remove.
(init_gnutls_functions): Do not load gnutls_global_set_mem_functions.
(fn_gnutls_global_set_mem_functions) [!WINDOWSNT]: Remove.
All uses removed.
(check_memory_full): New function.
(emacs_gnutls_handshake, emacs_gnutls_handle_error)
(gnutls_make_error, Fgnutls_boot): Use it.
(emacs_gnutls_global_init): Avoid gnutls_global_set_mem_functions.
src/xdisp.c (set_iterator_to_next) <GET_FROM_STRING>: Limit search in
composition_compute_stop_pos to the number of characters in the
string.
<GET_FROM_BUFFER, GET_FROM_STRING>: Simplify code.
src/composite.c (composition_compute_stop_pos): If no composition
was found in a string before ENDPOS, and ENDPOS is the string end,
no need to back up to a safe point.
src/dispextern.h (struct it) <end_charpos>: Improve commentary.
Fixes: debbugs:19133
* nsimage.m (allocInitFromFile:): Initialize bmRep.
(dealloc): Release bmRep.
(setPixmapData): Make bmRep local so class member is not
set.
Fixes: debbugs:19346
* gnutls.c (Fgnutls_available_p syms_of_gnutls): Move later for
clarity. Let the availability check return Qnil when the GnuTLS
integration is not available, instead of erroring out.
* gnutls.h: Always declare syms_of_gnutls.
* emacs.c (main): Always include gnutls.h and run syms_of_gnutls.
* nsfns.m (ns_set_name_as_filename): Don't set represented filename
at once, call ns_set_represented_filename instead.
* nsterm.h: Declare ns_set_represented_filename.
* nsterm.m (represented_filename, represented_frame): New variables.
(ns_set_represented_filename): New function.
(sendEvent:): Set represented filename here to avoid flicker,
related to Bug#18757.
src/xdisp.c (handle_single_display_spec): When ignoring a fringe
bitmap display, reset the ignore_overlay_strings_at_pos_p flag.
(next_element_from_buffer): When done with overlays, reset the
ignore_overlay_strings_at_pos_p flag.
* Makefile.in (temacs$(EXEEXT)): Use consistent flag settings
for paxctl and setfattr. Fixes temacs startup failure with
grsecurity/PaX enabled Linux kernel (bug#19067).
... for detecting MinGW-w64. _W64 is not specific of MinGW-w64, it is
defined for compatibility with MS VC++.
* nt/inc/ms-w32.h: Define MINGW_W64.
* admin/CPP-DEFINES: Mention MINGW_W64.
* nt/addpm.c: Use it.
* nt/addsection.c: Use it.
* nt/preprep.c: Use it.
* src/w32.c: Use MINGW_W64 instead of _W64
* src/w32term.c: Likewise.
src/window.c (window_scroll_pixel_based): Avoid truncation/rounding
errors in computing the number of pixels to scroll. Suggested by
Kelly Dean <kelly@prtime.org>.
* nsterm.m (init): Replace OSX 10.9 check with IMPL_COCOA.
(run): Ditto. Only use non-system event loop if OSX version is
exactly 10.9.
Fixes: debbugs:18993
src/xdisp.c (Fdump_glyph_matrix, Fdump_frame_glyph_matrix): Doc fix.
(Fdump_frame_glyph_matrix): Don't segfault if invoked on a GUI
frame; instead, print an error message.
