2012-09-05 Julien Danjou <julien@danjou.info>

  this hide the real reason with a message giving absolutely no hint.

2012-09-05 Lars Ingebrigtsen <larsi@gnus.org>

2012-09-05 Magnus Henoch <magnus.henoch@gmail.com>
* nnmaildir.el: Make nnmaildir understand and write maildir flags.
  That is, rename files from "unique:2," to "unique:2,S" for "seen", etc.
  This should make nnmaildir more usable with offlineimap.

Be more systematic about preserving errno whenever a signal
handler returns, even if it's not in the main thread.  Do this by
renaming signal handlers to distinguish between signal delivery
and signal handling.  All uses changed.
* atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
* data.c (deliver_arith_signal): Rename from arith_error.
* dispnew.c (deliver_window_change_signal): Rename from
window_change_signal.
* emacs.c (deliver_error_signal): Rename from fatal_error_signal.
(deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
* keyboard.c (deliver_input_available_signal): Rename from
input_available_signal.
(deliver_user_signal): Rename from handle_user_signal.
(deliver_interrupt_signal): Rename from interrupt_signal.
* process.c (deliver_pipe_signal): Rename from send_process_trap.
(deliver_child_signal): Rename from sigchld_handler.
* atimer.c (handle_alarm_signal):
* data.c (handle_arith_signal):
* dispnew.c (handle_window_change_signal):
* emacs.c (handle_fatal_signal, handle_danger_signal):
* keyboard.c (handle_input_available_signal):
* keyboard.c (handle_user_signal, handle_interrupt_signal):
* process.c (handle_pipe_signal, handle_child_signal):
New functions, with the actual signal-handling code taken from the
original respective signal handlers, sans the sporadic attempts to
preserve errno, since that's now done by handle_on_main_thread.
* atimer.c (alarm_signal_handler): Remove unnecessary decl.
* emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
* emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
Move to sysdep.c.
(main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
Move initialization of main_thread to sysdep.c's init_signals.
* process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
our usage, and simplifies the mainline code.
(record_child_status_change): New static function, as a helper
for handle_child_signal, and with most of the old child handler's
contents.
(CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
(handle_child_signal): Use the above.
* sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
Moved here from emacs.c.
(init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
code moved here from emacs.c's main function.
* sysdep.c, syssignal.h (handle_on_main_thread): New function,
replacing the old SIGNAL_THREAD_CHECK.  All uses changed.  This
lets callers save and restore errno properly.

* lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
* conf_post.h (RE_TRANSLATE): Use char_table_translate.
* editfns.c (Fcompare_buffer_substrings): Likewise.
* frame.h (struct terminal, struct font_driver_list):
Remove redundant declarations.
* window.h (Qleft, Qright): Likewise.

* alloc.c (mark_buffer): Mark just the buffer if it is dead.

(fit-frame-to-buffer): New function.

* fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
(Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
(file_name_absolute_p, Fsubstitute_in_file_name):
(check_executable, check_writable, Ffile_accessible_directory_p)
(Fset_file_selinux_context, Fdefault_file_modes)
(Finsert_file_contents, choose_write_coding_system)
(Fwrite_region, build_annotations, a_write, e_write)
(Fdo_auto_save):
* filelock.c (boot_time_initialized, get_boot_time)
(get_boot_time_1, lock_file_1, within_one_second):
* floatfns.c (in_float):
* fns.c (concat, internal_equal, Frequire, base64_encode_1)
(base64_decode_1, cmpfn_eql, cmpfn_user_defined)
(sweep_weak_table, sweep_weak_hash_tables, secure_hash):
* lisp.h (struct Lisp_Hash_Table.cmpfn):
* window.c (compare_window_configurations):
Use bool for booleans.
* fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
(Fdefault_file_modes): Now mode_t, not int, for modes.
(Fdo_auto_save): Set a boolean to 1 rather than using ++.
(internal_delete_file): Now returns void, not a (boolean) int,
since nobody was looking at the return value.
* lisp.h, window.h: Adjust to above API changes.

This allows tracking down what piece of code is outputting stuff in
the echo area.

* eval.c (call_debugger): Make the function non-static so that we
can call it from set_message.

* xdisp.c (set_message): Implement the new variable `debug-on-message'.
(syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.

* doc/emacs/trouble.texi (Crashing): New section, documenting this.
* etc/NEWS: Document the change.
* src/alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
(die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
of doing the work ourselves.
* src/emacs.c (fatal_error_signal): Let fatal_error_backtrace
do most of the work.
(fatal_error_backtrace): New function, taken from the guts
of the old fatal_error_signal, but with a new option to output
a backtrace.
(shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
info about the signal than just its number.
* src/lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
* src/sysdep.c: Include <execinfo.h>
(emacs_backtrace): New function, taken partly from the previous
code of the 'die' function.
(emacs_abort): Call fatal_error_backtrace rather than abort.

eager (load-time) macro-expansion.

* lisp/emacs-lisp/macroexp.el (macroexp--eval-if-compile): New function.
(macroexp--expand-all): Use it to get better warnings.
(macroexp--backtrace, macroexp--trim-backtrace-frame)
(internal-macroexpand-for-load): New functions.
(macroexp--pending-eager-loads): New var.
(emacs-startup-hook): New hack to replace one in loadup.el.
* lisp/emacs-lisp/cl-macs.el (cl--compiler-macro-list*)
(cl--compiler-macro-cXXr): Move to top, before they can be used.
(cl-psetf): Simplify.
(cl-defstruct): Add indent rule.

Do not try to redefine the 'abort' function.  Instead, redo
the code so that it calls 'emacs_abort' rather than 'abort'.
This removes the need for the NO_ABORT configure-time macro
and makes it easier to change the abort code to do a backtrace.
* configure.ac (NO_ABRT): Remove.
* admin/CPP-DEFINES (NO_ABORT): Remove.
* nt/inc/ms-w32.h (w32_abort) [HAVE_NTGUI]: Remove.
* src/.gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
* src/emacs.c (abort) [!DOS_NT && !NO_ABORT]:
Remove; sysdep.c's emacs_abort now takes its place.
* src/lisp.h (emacs_abort): New decl.  All calls from Emacs code to
'abort' changed to use 'emacs_abort'.
* src/msdos.c (dos_abort) [defined abort]: Remove; not used.
(abort) [!defined abort]: Rename to ...
(emacs_abort): ... new name.
* src/sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
the place of the old 'abort' in emacs.c.
* src/w32.c, src/w32fns.c (abort): Do not #undef.
* src/w32.c (emacs_abort): Rename from w32_abort.

 src/w32uniscribe.c (uniscribe_shape): Reverse the sign of
 offsets[j].dv, since the y axis of the screen coordinates points
 down, while the y axis of the font definition coordinates points
 up.  This fixes display of Arabic diacritics such as KASRA and
 KASRATAN.

* mail/smtpmail.el (smtpmail-send-it): Prefer the From: header
over `user-mail-address' for the SMTP MAIL FROM envelope.
(smtpmail-via-smtp): Ditto.

* alloc.c (test_setjmp, mark_stack):
* image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
(PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
(png_load, my_error_exit, jpeg_load):
* process.c (send_process_trap, send_process):
Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
The underscored versions are up to 30x faster on some hosts.
Formerly, the code used setjmp+longjmp sometimes and
_setjmp+_longjmp at other times, with no particular reason to
prefer setjmp+longjmp.

instead of by guessing.  The guesses were wrong for
recent versions of Solaris, such as Solaris 11.

(ruby-mode-map): Don't bind ruby-electric-brace,
ruby-beginning-of-defun, ruby-end-of-defun, ruby-mark-defun,
backward-kill-word, reindent-then-newline-and-indent.
(ruby-mark-defun): Remove.
(ruby-electric-brace): Remove.  Obsoleted by electric-indent-chars.
(ruby-mode): Set local beginning-of-defun-function and
end-of-defun-function values.

It generates false alarms in doc.c, regex.c, xdisp.c.  See
<http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00040.html>.

EXCLUDE_SUBRS_P.  All callers changed.

Mostly, this hoists extern decls out of .c files and into .h files.
That way, we're more likely to catch errors if the interfaces change.
* alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
declare xg_mark_data.
