* window.c (Fsplit_window_internal): Set combination limit of
new parent window to t iff Vwindow_combination_limit is t;
fixing a regression introduced with the change from 2012-09-22.
(Fwindow_combination_limit, Fset_window_combination_limit): Fix
doc-strings.
* elisp.texi (Top): Add Recombining Windows to menu.
* windows.texi (Recombining Windows): New subsection.
(Splitting Windows): Rewrite text on handling of window
combinations and move it to new subsection.
src/xdisp.c (try_scrolling): Fix correction of aggressive-scroll
amount when the scroll margins are too large. When scrolling
backwards in the buffer, give up if cannot reach point or the
scroll margin within a reasonable number of screen lines. Fixes
point position in window under scroll-up/down-aggressively when
point is positioned many lines beyond the window top/bottom.
config.bat: Copy lib/execinfo.in.h to lib/execinfo.in-h if needed.
msdos/sedlibmk.inp: Sync with changes in lib/Makefile.in.
(HAVE_DECL_ENVIRON, GNULIB_ENVIRON): Edit to require declaration
through lib/unistd.h.
msdos/sed1v2.inp: Sync with changes in src/Makefile.in.
msdos/sed2v2.inp: Sync with changes in src/config.in.
src/lisp.mk: Adjust comments to the fact that term/internal is now
loaded from loadup.el.
src/msdos.c (msdos_abort): Rename from emacs_abort, and make static.
(msdos_fatal_signal): New function.
(XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
its argument list.
src/conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
for GCC versions before 4.
(emacs_raise): Define to call msdos_fatal_signal.
lisp/term/pc-win.el: Don't load term/internal from here.
lisp/loadup.el: Load term/internal from here.
* widget.c (resize_cb): New function.
(EmacsFrameRealize): Add resize_cb as event handler.
(EmacsFrameResize): Check if all is up to date before changing frame
size.
Fixes: debbugs:12733
src/xdisp.c (init_from_display_pos): Fix initialization of the bidi
iterator when starting in the middle of a display or overlay
string.
Fixes: debbugs:12745
* callproc.c (setpgrp): Remove macro, as we now use setpgid
and it is configured in conf_post.h.
(Fcall_process): Don't invoke both setsid and setpgid; the former
is enough, if it exists.
* callproc.c (Fcall_process, child_setup):
* process.c (create_process): Use setpgid.
* conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
for the real thing.
* dispnew.c (init_display): Initialize the foreground group
if we are running a tty display.
* emacs.c (main): Do not worry about setpgrp; init_display does it now.
* lisp.h (init_foreground_group): New decl.
* sysdep.c (inherited_pgroup): New static var.
(init_foreground_group, tcsetpgrp_without_stopping)
(narrow_foreground_group, widen_foreground_group): New functions.
(init_sys_modes): Narrow foreground group.
(reset_sys_modes): Widen foreground group.
Fixes: debbugs:12697
* window.el (quit-restore-window): If the window has been
created on an existing frame and ended up as the sole window on
that frame, do not delete it (Bug#12764).
* minibuf.c (read_minibuf): Restore current buffer since
choose_minibuf_frame calling Fset_frame_selected_window may
change it (Bug#12766).
cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode): In
preparation for fixing bug#12739, move these functions from
here...
* coding.h, coding.c: ... to here, and compile them only when
WINDOWSNT or HAVE_NTGUI. Moving these functions out of cygw32
proper lets us write cygw32-agnostic code for the HAVE_NTGUI case.
src/w32proc.c (TIMER_TICKS_PER_SEC): New macro.
(timer_loop, getitimer, setitimer): Use it instead of
CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
'clock'.
(w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
literal 10000.
(last_appdefined_event_data): New variable
(last_appdefined_event): Remove.
(ns_select): Initialize t from last_appdefined_event_data instead
of [last_appdefined_event data1].
(sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
remove last_appdefined_event.
Fixes: debbugs:12698
Avoid overflow in w32 implementation of interval timers. When
possible, for ITIMER_PROF count only times the main thread
actually executes.
src/w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
ULONGLONG types. Likewise for all the other data which was
previously clock_t.
(GetThreadTimes_Proc): New typedef.
(w32_get_timer_time): New function, returns a suitable time value
for the timer.
(timer_loop): Enter critical section when accessing ULONGLONG
values of the itimer_data struct, as these accesses are no longer
atomic. Call 'w32_get_timer_time' instead of 'clock'.
(init_timers): Initialize s_pfn_Get_Thread_Times.
(start_timer_thread): Don't assign itimer->caller_thread here.
(getitimer): Assign itimer->caller_thread here.
(setitimer): Always call getitimer to get the value of ticks_now.
src/w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
mouse movement events if the menu bar is active. This avoids
producing a busy "hour-glass" cursor by Windows if the mouse
pointer is positioned over a tooltip shown for some menu item.
* emacs.c (shut_down_emacs) [!DOS_NT]:
* sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
* term.c (dissociate_if_controlling_tty) [!DOS_NT]:
Use pid_t, not int, to store process IDs, as 'int'
is not wide enough on a few platforms (e.g., AIX and IRIX).
* frame.c (Fmouse_position, Fmouse_pixel_position):
* xdisp.c (produce_stretch_glyph):
Declare local vars only when they're needed.
This is clearer and avoids a warning on OpenBSD about unused vars.
* frame.h (FRAME_WINDOW_P): Always evaluate its argument.
This is safer, and avoids OpenBSD warnings about unused vars.
* keyboard.c (record_menu_key): Remove unnecessary decl.
(poll_timer): Define only if POLL_FOR_INPUT is defined.
* unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
as our definition clashes with OpenBSD's.
* xfaces.c (load_face_colors, check_lface_attrs)
(get_lface_attributes_no_remap, get_lface_attributes)
(lface_fully_specified_p, x_supports_face_attributes_p)
(tty_supports_face_attributes_p, face_fontset, realize_face)
(realize_x_face, realize_tty_face):
Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
merely Lisp_Object *. This is more informative and avoids
a warning on OpenBSD about accessing beyond an object's size.
* .bzrignore: Add lib/fcntl.h.
* configure.ac (euidaccess): Remove check; gnulib does this for us now.
(gl_FCNTL_O_FLAGS): Define a dummy version.
* lib/at-func.c, lib/euidaccess.c, lib/faccessat.c, lib/fcntl.in.h:
* lib/getgroups.c, lib/group-member.c, lib/root-uid.h:
* lib/xalloc-oversized.h, m4/euidaccess.m4, m4/faccessat.m4:
* m4/fcntl_h.m4, m4/getgroups.m4, m4/group-member.m4:
New files, from gnulib.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* admin/merge-gnulib (GNULIB_MODULES): Add faccessat.
(GNULIB_TOOL_FLAGS): Avoid at-internal, fchdir, malloc-posix,
openat-die, openat-h, save-cwd. Do not avoid fcntl-h.
Omit gnulib's m4/fcntl-o.m4.
* nt/inc/ms-w32.h (AT_FDCWD, AT_EACCESS): New symbols.
(access): Remove.
(faccessat): New macro.
* src/Makefile.in (LIB_EACCESS): New macro.
(LIBES): Use it.
* src/callproc.c (init_callproc):
* src/charset.c (init_charset):
* src/fileio.c (check_existing, check_executable):
* src/lread.c (openp, load_path_check):
* src/process.c (allocate_pty):
* src/xrdb.c (file_p):
Use faccessat, not access or euidaccess. Use symbolic names
instead of integers for the flags, as they're portable now.
* src/charset.c, src/xrdb.c: Include <fcntl.h>, for the new flags used.
* src/fileio.c (Ffile_readable_p):
Use faccessat, not stat + open + close.
(file_directory_p): New function, which uses 'stat' on most places
but 'access' (for efficiency) if WINDOWSNT.
* src/fileio.c (Ffile_directory_p, Fset_file_times):
* src/xrdb.c (file_p): Use file_directory_p.
* src/lisp.h (file_directory_p): New decl.
* src/lread.c (openp): When opening a file, use fstat rather than
stat, as that avoids a permissions race. When not opening a file,
use file_directory_p rather than stat.
* src/process.c, src/sysdep.c, src/term.c: All uses of '#ifdef O_NONBLOCK'
changed to '#if O_NONBLOCK', to accommodate gnulib O_* tyle.
* src/w32.c (sys_faccessat): Rename from sys_access and switch to
faccessat's API. All uses changed.
