* admin/merge-gnulib (GNULIB_MODULES): Add close-stream.
* lib/close-stream.c, lib/close-stream.h, lib/fpending.c
* lib/fpending.h, m4/close-stream.m4, m4/fpending.m4:
New files, from gnulib.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* src/emacs.c: Include <close-stream.h>.
(close_output_streams): New function.
(main): Pass it to atexit, so that Emacs closes stdout and stderr
and handles errors appropriately.
(Fkill_emacs): Don't worry about flushing, as close_output_stream
does that now.
Fixes: debbugs:9574
The symptom is a diagnostic "GLib-WARNING **: In call to
g_spawn_sync(), exit status of a child process was requested but
SIGCHLD action was set to SIG_IGN and ECHILD was received by
waitpid(), so exit status can't be returned." The diagnostic
is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
The real bug is a race condition between Emacs and glib: Emacs
does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
so that glib can't find it. Work around the bug by invoking
waitpid only on subprocesses that Emacs itself creates.
* process.c (create_process, record_child_status_change):
Don't use special value -1 in pid field, as the caller now must
know the pid rather than having the callee infer it. The
inference was sometimes incorrect anyway, due to another race.
(create_process): Set new 'alive' member if child is created.
(process_status_retrieved): New function.
(record_child_status_change): Use it.
Accept negative 1st argument, which means to wait for the
processes that Emacs already knows about. Move special-case code
for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
processes that have already been waited for, by testing and
clearing new 'alive' member.
(CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
now does this internally.
(handle_child_signal): Let record_child_status_change do all
the work, since we do not want to reap all exited child processes,
only the child processes that Emacs itself created.
* process.h (Lisp_Process): New boolean member 'alive'.
Fixes: debbugs:8855
* lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
(VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
Define only as macros. There's no longer any need to also define
these symbols as enums or as constants, since we now assume
gcc -g3 when debugging.
* cl.texi: Further general copyedits.
(List Functions): Remove copy-tree, standard elisp for some time.
(Efficiency Concerns): Comment out examples that no longer apply.
(Compiler Optimizations): Rename from "Optimizing Compiler"; reword.
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
* objects.texi (General Escape Syntax): Clarify the explanation of
escape sequences.
(Non-ASCII in Strings): Clarify when a string is unibyte vs
multibyte. Hex escapes do not automatically make a string multibyte.
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
which is meaningless for a long time. Adjust comments.
(FRAME_CAN_HAVE_SCROLL_BARS): Remove.
* frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
2012-10-05 Katsumi Yamaoka <yamaoka@jpl.org>
* gnus.texi (Mail Source Specifiers):
Document :leave keyword used for pop mail source.
2012-10-25 Tassilo Horn <tsdh@gnu.org>
* gnus-dired.el (gnus-dired-attach): Attach to last used message buffer
by default. Patch provided by Stephen Eglen.
2012-10-05 Katsumi Yamaoka <yamaoka@jpl.org>
New UIDL implementation.
* mail-source.el (mail-sources, mail-source-keyword-map):
Add :leave as a pop3 keyword.
(mail-source-fetch-pop): Bind pop3-leave-mail-on-server.
* pop3.el (pop3-leave-mail-on-server): Allow number.
(pop3-uidl-file, pop3-uidl-file-backup): New user options.
(pop3-movemail): Add UIDL support.
(pop3-send-streaming-command): Take a list of mail numbers instead of
the number of mails.
(pop3-write-to-file): Add X-UIDL header.
(pop3-uidl-stat, pop3-uidl-dele, pop3-uidl-load, pop3-uidl-save)
(pop3-uidl-add-xheader): New functions.
* message.el (message-ignored-resent-headers):
Add X-Content-Length and X-UIDL headers.
src/w32fns.c (CaptureStackBackTrace_proc): New typedef.
(BACKTRACE_LIMIT_MAX): New macro.
(w32_backtrace): New function.
(emacs_abort): Use w32_backtrace when the user chooses not to
attach a debugger. Update the text of the abort dialog.
* termhooks.h (struct input_event): Remove padding field.
Adjust comment.
* keyboard.c (event_to_kboard): Simplify because frame_or_window
member is never cons for a long time. Adjust comment.
(mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
* xterm.c (handle_one_xevent): Do not initialize frame_or_window
field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
