Vinternal__top_level_message, as suggested by Stefan Monnier in
http://lists.gnu.org/archive/html/emacs-devel/2014-08/msg00493.html
All related users changed.
* lisp/startup.el (normal-top-level): Now use internal--top-level-message.
* doc/lispref/eval.texi (Eval): Mention possible recovery from stack overflow.
* configure.ac: Check for sigaltstack and related sigaction
support. Unconditionally check for sigsetjmp and siglongjmp.
(HAVE_STACK_OVERFLOW_HANDLING): Define if we can support it.
* src/lisp.h (toplevel) [HAVE_STACK_OVERFLOW_HANDLING]: Declare
siglongjmp point to transfer control from SIGSEGV handler.
* src/keyboard.c (return_to_command_loop, recover_top_level_message)
[HAVE_STACK_OVERFLOW_HANDLING]: New variables.
(regular_top_level_message): New variable.
(command_loop) [HAVE_STACK_OVERFLOW_HANDLING]: Handle non-local
exit from SIGSEGV handler and adjust message displayed by Vtop_level
if appropriate.
(syms_of_keyboard): DEFVAR Vtop_level_message and initialize
new variables described above.
* src/sysdep.c [HAVE_SYS_RESOURCE_H]: Include sys/resource.h as such.
(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.
cc-engine.el (c-forward-type): Enhance to recognise and return 'decltype.
(c-forward-decl-or-cast-1): New let variables backup-kwd-sym,
prev-kwd-sym, new-style-auto. Enhance to handle the new "auto" keyword.
cc-fonts.el (c-font-lock-declarations): Handle the "decltype" keyword.
(c-font-lock-c++-new): Handle "decltype" constructions.
cc-langs.el (c-auto-ops, c-auto-ops-re): New c-lang-defconsts/defvars.
(c-haskell-op, c-haskell-op-re): New c-lang-defconsts/defvars.
(c-typeof-kwds, c-typeof-key): New c-lang-defconsts/defvars.
(c-typeless-decl-kwds): Append "auto" onto the C++ value.
(c-not-decl-init-keywords): Also exclude c-typeof-kwds from value.
cc-langs.el (c->-op-cont-tokens): New lang-const split off from
c->-op-cont-re.
(c->-op-cont-tokens): Change to use the above.
(c->-op-without->-cont-regexp): New lang-const.
cc-engine.el (c-forward-<>-arglist-recur): Use
c->-op-without->-cont-regexp in place of c->-op-cont-tokens.
lisp/textmodes/texnfo-upd.el (texinfo-specific-section-type): Don't
recognize a Top node if there are other sectioning commands
earlier in the Texinfo file. This fixes a bug in
texinfo-make-menu and avoids inflooping in
texinfo-all-menus-update when they are invoked on texinfo.texi.
* window.el (window--side-window-p): New function.
(split-window, window-splittable-p): Use window--side-window-p to
determine whether WINDOW can be split (Bug#18304).
* calendar/calendar.el (calendar-basic-setup): Fix one call of
`window-splittable-p' and add another (Bug#18304).
for &key args.
* emacs-lisp/eldoc.el (eldoc-argument-case): Obsolete and change default.
(eldoc-function-argstring-format): Remove.
(eldoc-function-argstring): Always return upcase args.
Use help-make-usage. Don't add parens.
(eldoc-get-fnsym-args-string): Don't obey eldoc-argument-case since
it's too late to do it right (bug#18048).
lisp/scroll-bar.el (scroll-bar-horizontal-drag-1)
(scroll-bar-toolkit-horizontal-scroll): When determining the
paragraph direction, use the buffer of the window designated in
the event.
Without this, for example, 'make -j bootstrap' can fail and report
"Opening input file: no such file or directory,
.../lisp/calendar/diary-loaddefs.el ... recipe for target
'calendar/hol-loaddefs.el' failed", where the hol-loaddefs.el rule
got confused because diary-loaddefs.el was being built in parallel.
* Makefile.in ($(CAL_DIR)/diary-loaddefs.el):
Depend on $(CAL_DIR)/cal-loaddefs.el.
($(CAL_DIR)/hol-loaddefs.el): Depend on $(CAL_DIR)/diary-loaddefs.el.
* w32term.c (w32_horizontal_scroll_bar_handle_click): In y part
of emacs_event return length from si.nPage to si.nMax.
* xdisp.c (set_horizontal_scroll_bar): For right-to-left text
interchange start and end of thumb.
* scroll-bar.el (scroll-bar-horizontal-drag-1): Use cdr of
portion-whole for scrolling right-to-left text.
* image-mode.el (image-transform-reset): New command and menu item.
(image-mode-map): Rearrange the menu items to put presumably more
obscure items at the end.
It causes a more serious problem than the one it solves.
This closes bug#18141, and reopens bug#13522.
* lisp/files.el (basic-save-buffer-2): Revert 2013-01-31 change.
* src/fileio.c: Revert 2013-01-31 change.
(choose_write_coding_system): No longer callable from Lisp.
Move last piece back here from Fwrite_region.
(Fwrite_region, syms_of_fileio): Update for above changes.
* test/automated/data/files-bug18141.el.gz: New file.
* test/automated/files.el (files-test-bug-18141-file):
New variable and test.
top-level that can cause unacceptable slow-down in scrolling.
See email Subject: Huge {...} blocks in C/C++ again, from Dmitry Antipov
from 2013-10-14 in emacs-devel.
* window.el (display-buffer-below-selected): Restore original
behavior if buffer is already displayed in the window below the
selected one (Bug#18181).
