Merge Changes made in Gnus master

2013-07-19 Geoff Kuenning <geoff@cs.hmc.edu> (tiny change)
 * gnus.texi (Customizing Articles): Document function predicates.

2013-07-19 Geoff Kuenning <geoff@cs.hmc.edu> (tiny change)
 * gnus-art.el (gnus-treat-predicate): Allow functions as predicates (bug#13384).

2013-07-18 Lars Magne Ingebrigtsen <larsi@gnus.org>
 * gnus-start.el (gnus-clean-old-newsrc): Remove the newsrc cleanups
 that were only relevant in a development version a long time ago.

eww textarea input fixup

* net/eww.el (eww-process-text-input): Allow inputting when the
point is at the start of the line, as the properties aren't
front-sticky.

* conf_post.h (RE_TRANSLATE_P) [emacs]: Remove obsolete optimization.

(shr-make-table-1): Ensure that we don't infloop on degenerate widths.

* epa.el (epa-popup-info-window): Doc fix.

Add a comment.

split-string takes a new arg TRIM that's a regexp
saying what to trim from the start and end of each substring.

* subr.el (split-string): New arg TRIM.

Fix the fix for bug #14901.

 src/keyboard.c (kbd_buffer_get_event): Use Display_Info instead of
 unportable 'struct x_display_info'.
 (DISPLAY_LIST_INFO): Delete macro: not needed, since Display_Info
 is a portable type.

* doc/lispref/windows.texi (Display Action Functions): Mention next-window.

* sysdep.c [GNU_LINUX]: Fix fd and memory leaks and similar issues.

(procfs_ttyname): Don't use uninitialized storage if emacs_fopen
or fscanf fails.
(system_process_attributes): Prefer plain char to unsigned char
when either will do.  Clean up properly if interrupted or if
memory allocations fail.  Don't assume sscanf succeeds.  Remove
no-longer-needed workaround to stop GCC from whining.  Read
command-line once, instead of multiple times.  Check read status a
bit more carefully.

Fix obscure porting bug with varargs functions.

The code assumed that int is treated like ptrdiff_t in a vararg
function, which is not a portable assumption.  There was a similar
-- though these days less likely -- porting problem with various
assumptions that pointers of different types all smell the same as
far as vararg functions is conserved.  To make this problem less
likely in the future, redo the API to use varargs functions.
* alloc.c (make_save_value): Remove this vararg function.
All uses changed to ...
(make_save_int_int_int, make_save_obj_obj_obj_obj)
(make_save_ptr_int, make_save_funcptr_ptr_obj, make_save_memory):
New functions.
(make_save_ptr): Rename from make_save_pointer, for consistency with
the above.  Define only on platforms that need it.  All uses changed.

lisp/ChangeLog, src/ChangeLog: Fix typos.

* keyboard.c: Try to fix typos in previous change.

(DISPLAY_LIST_INFO): New macro.
(kbd_buffer_get_event): Do not access members that are not present
in X11.  Revert nadvertent change of "!=" to "=".

Followup to 2013-07-16T11:41:06Z!jan.h.d@swipnet.se.
* lisp/frame.el (blink-cursor-timer-function, blink-cursor-suspend):
  Add check for W32.
* src/keyboard.c (kbd_buffer_get_event):
* src/w32term.c (x_focus_changed): Port FOCUS_(IN|OUT)_EVENT changes to W32.

gnus-art.el (gnus-shr-put-image): Make it work as well for shr.el's that the old Emacs 24s bundle

* filelock.c: Fix unlikely file descriptor leaks.

(get_boot_time_1): Rework to avoid using emacs_open.
This doesn't actually fix a leak, but is better anyway.
(read_lock_data): Use read, not emacs_read.

* filenotify.el (file-notify--library): Renamed from
`file-notify-support'.  Do not autoload.  Adapt all uses.
(file-notify-supported-p): New defun.

* autorevert.el (auto-revert-use-notify): Use
`file-notify-supported-p' instead of `file-notify-support'.  Adapt
docstring.
(auto-revert-notify-add-watch): Use `file-notify-supported-p'.

* net/tramp.el (tramp-file-name-for-operation):
Add `file-notify-supported-p'.

* net/tramp-sh.el (tramp-sh-handle-file-notify-supported-p):
New defun.
(tramp-sh-file-name-handler-alist): Add it as handler for
`file-notify-supported-p '.

* net/tramp-adb.el (tramp-adb-file-name-handler-alist):
* net/tramp-gvfs.el (tramp-gvfs-file-name-handler-alist):
* net/tramp-smb.el (tramp-smb-file-name-handler-alist):
Add `ignore' as handler for `file-notify-*' functions.

* doc.c: Fix minor memory and file descriptor leaks.

* doc.c (get_doc_string): Fix memory leak when doc file absent.
(get_doc_string, Fsnarf_documentation):
Fix file descriptor leak on error.

* term.c: Fix minor fdopen-related file descriptor leaks.

* term.c (Fresume_tty) [!MSDOS]: Close fd if fdopen (fd) fails.
(init_tty) [!DOS_NT]: Likewise.  Also close fd if isatty (fd) fails.

* charset.c: Fix file descriptor leaks and errno issues.

Include <errno.h>.
(load_charset_map_from_file): Don't leak file descriptor on error.
Use plain record_xmalloc since the allocation is larger than
MAX_ALLOCA; that's simpler here.  Simplify test for exhaustion
of entries.
* eval.c (record_unwind_protect_nothing):
* fileio.c (fclose_unwind):
New functions.
* lread.c (load_unwind): Remove.  All uses replaced by fclose_unwind.
The replacement doesn't block input, but that no longer seems
necessary.

* lread.c: Fix file descriptor leaks and errno issues.

(Fload): Close some races that leaked fds or streams when 'load'
was interrupted.
(Fload, openp): Report error number of last nontrivial failure to open.
ENOENT counts as trivial.
* eval.c (do_nothing, clear_unwind_protect, set_unwind_protect_ptr):
New functions.
* fileio.c (close_file_unwind): No need to test whether FD is nonnegative,
now that the function is always called with a nonnegative arg.
* lisp.h (set_unwind_protect_ptr, set_unwind_protect_int): Remove.
All uses replaced with ...
(clear_unwind_protect, set_unwind_protect_ptr): New decls.

Fix bug #14881 with scrolling images smaller than the window height.

 lisp/simple.el (line-move-partial, line-move): Don't start vscroll or
 scroll-up if the current line is not taller than the window.

A few more minor file errno-reporting bugs.

* callproc.c (Fcall_process):
* doc.c (Fsnarf_documentation):
* fileio.c (Frename_file, Fadd_name_to_file, Fmake_symbolic_link):
* process.c (set_socket_option):
Don't let a constructor trash errno.
* doc.c: Include <errno.h>.

src/w32fns.c (unwind_create_tip_frame): Fix declaration.

Fix w32 bug with call-process-region.

* callproc.c (Fcall_process_region): Pass nil, not "/dev/null",
to Fcall_process when the input is empty.  This simplifies the
code a bit.  It makes no difference on POSIXish platforms but
apparently it fixes a bug on w32.

Fixes: debbugs:14885

Fix bug where insert-file-contents closes a file twice.

* fileio.c (close_file_unwind): Don't close if FD is negative;
this can happen when unwinding a zapped file descriptor.
(Finsert_file_contents): Unwind-protect the fd before the point marker,
in case Emacs runs out of memory between the two unwind-protects.
Don't trash errno when closing FD.
Zap the FD in the specpdl when closing it, instead of deferring
the removal of the unwind-protect; this fixes a bug where a child
function unwinds the stack past us.

Fixes: debbugs:14839

New unwind-protect flavors to better type-check C callbacks.

This also lessens the need to write wrappers for callbacks,
and the need for make_save_pointer.
* alloca.c (free_save_value):
* atimer.c (run_all_atimers):
Now extern.
* alloc.c (safe_alloca_unwind):
* atimer.c (unwind_stop_other_atimers):

Remove no-longer-needed wrapper.  All uses replaced by the wrappee.
* alloca.c (record_xmalloc):
Prefer record_unwind_protect_ptr to record_unwind_protect with
make_save_pointer.
* alloca.c (Fgarbage_collect):
Prefer record_unwind_protect_void to passing a dummy.
* buffer.c (restore_buffer):
* window.c (restore_window_configuration):
* xfns.c, w32fns.c (do_unwind_create_frame)
New wrapper.  All record-unwind uses of wrappee changed.
* buffer.c (set_buffer_if_live):
* callproc.c (call_process_cleanup, delete_temp_file):
* coding.c (code_conversion_restore):
* dired.c (directory_files_internal_w32_unwind) [WINDOWSNT]:
* editfns.c (save_excursion_restore)
(subst_char_in_region_unwind, subst_char_in_region_unwind_1)

(fast_set_selected_frame):
* xfns.c, w32fns.c (unwind_create_tip_frame):
Return void, not a dummy Lisp_Object.  All uses changed.
* buffer.h (set_buffer_if_live): Move decl here from lisp.h.
* callproc.c (call_process_kill):

* xdisp.c (unwind_redisplay):
* xfns.c (clean_up_dialog):
* xselect.c (x_selection_request_lisp_error, x_catch_errors_unwind):
Accept no args and return void, instead of accepting and returning
a dummy Lisp_Object.  All uses changed.
* cygw32.c (fchdir_unwind):
* fileio.c (close_file_unwind):
* keyboard.c (restore_kboard_configuration):
* lread.c (readevalllop_1):
* process.c (wait_reading_process_output_unwind):
Accept int and return void, rather than accepting an Emacs integer
and returning a dummy object.  In some cases this fixes an
unlikely bug when the corresponding int is outside Emacs integer
range.  All uses changed.
* dired.c (directory_files_internal_unwind):
* fileio.c (do_auto_save_unwind):
* gtkutil.c (pop_down_dialog):
* insdel.c (reset_var_on_error):
* lread.c (load_unwind):

* xmenu.c, nsmenu.m (pop_down_menu):
* xmenu.c (cleanup_widget_value_tree):
* xselect.c (wait_for_property_change_unwind):
Accept pointer and return void, rather than accepting an Emacs
save value encapsulating the pointer and returning a dummy object.
All uses changed.
* editfns.c (Fformat): Update the saved pointer directly via
set_unwind_protect_ptr rather than indirectly via make_save_pointer.
* eval.c (specpdl_func): Remove.  All uses replaced by definiens.
(unwind_body): New function.
(record_unwind_protect): First arg is now a function returning void,
not a dummy Lisp_Object.
(record_unwind_protect_ptr, record_unwind_protect_int)
(record_unwind_protect_void): New functions.
(unbind_to): Support SPECPDL_UNWIND_PTR etc.
* fileio.c (struct auto_save_unwind): New type.
(do_auto_save_unwind): Use it.
(do_auto_save_unwind_1): Remove; subsumed by new do_auto_save_unwind.
* insdel.c (struct rvoe_arg): New type.
(reset_var_on_error): Use it.
* lisp.h (SPECPDL_UNWIND_PTR, SPECPDL_UNWIND_INT, SPECPDL_UNWIND_VOID):
New constants.
(specbinding_func): Remove; there are now several such functions.
(union specbinding): New members unwind_ptr, unwind_int, unwind_void.
(set_unwind_protect_ptr): New function.
* xselect.c: Remove unnecessary forward decls, to simplify maintenance.

* lisp/progmodes/ruby-mode.el (ruby-block-beg-keywords): Inline.
(ruby-font-lock-keyword-beg-re): Extract from
`ruby-font-lock-keywords'.

Be simpler and more consistent about reporting I/O errors.

* fileio.c (Fcopy_file, Finsert_file_contents, Fwrite_region):
Say "Read error" and "Write error", rather than "I/O error", or
"IO error reading", or "IO error writing", when a read or write
error occurs.
* process.c (Fmake_network_process, wait_reading_process_output)
(send_process, Fprocess_send_eof, wait_reading_process_output):
Capitalize diagnostics consistently.  Put "failed foo" at the
start of the diagnostic, so that we don't capitalize the
function name "foo".  Consistently say "failed" for such
diagnostics.
* sysdep.c, w32.c (serial_open): Now accepts Lisp string, not C string.
All callers changed.  This is so it can use report_file_error.
* sysdep.c (serial_open, serial_configure): Capitalize I/O
diagnostics consistently as above.

* fileio.c (report_file_errno): Fix errno reporting bug.

If the file name is neither null nor a pair, package it up as a
singleton list.  All callers changed, both to this function and to
report_file_error.  This fixes a bug where the memory allocator
invoked by list1 set errno so that the immediately following
report_file_error reported the wrong errno value.

Fix minor problems found by --enable-gcc-warnings.

* frame.c (Fhandle_focus_in, Fhandle_focus_out): Return a value.
* keyboard.c (kbd_buffer_get_event): Remove unused local.

* lisp/progmodes/ruby-mode.el (ruby-font-lock-keywords): Do not
highlight question marks in the method names as strings.

Stop cursor blink after blink-cursor-blinks (10), stop timers when not blinking.

* etc/NEWS: Document blink-cursor-blinks and blink timers stopped.

* lisp/frame.el (blink-cursor-blinks): New defcustom.
(blink-cursor-blinks-done): New defvar.
(blink-cursor-start): Set blink-cursor-blinks-done to 1.
(blink-cursor-timer-function): Check if number of blinks has been
done on X and NS.
(blink-cursor-suspend, blink-cursor-check): New defuns.

* src/frame.c (Fhandle_focus_in, Fhandle_focus_out): New functions.
(Fhandle_switch_frame): Call Fhandle_focus_in.
(syms_of_frame): defsubr handle-focus-in/out.

* src/keyboard.c (Qfocus_in, Qfocus_out): New static objects.
(make_lispy_focus_in, make_lispy_focus_out): Declare and define.
(kbd_buffer_get_event): For FOCUS_IN, make a focus_in event if no
switch frame event is made.  Check ! NILP (event->arg) if X11 (moved
from xterm.c). Make focus_out event for FOCUS_OUT_EVENT if NS or X11
and there is a focused frame.
(head_table): Add focus-in and focus-out.
(keys_of_keyboard): Add focus-in and focus-out to Vspecial_event_map,
bind to handle-focus-in/out.

* src/nsterm.m (windowDidResignKey): If this is the focused frame, generate
FOCUS_OUT_EVENT.

* src/termhooks.h (enum event_kind): Add FOCUS_OUT_EVENT.

* src/xterm.c (x_focus_changed): Always generate FOCUS_IN_EVENT.
Set event->arg to Qt if switch-event shall be generated.
Generate FOCUS_OUT_EVENT for FocusOut if this is the focused frame.

Fix porting bug to older POSIXish platforms.

* sysdep.c (emacs_pipe): New function, that implements
pipe2 (fd, O_CLOEXEC) even on hosts that lack O_CLOEXEC.
This should port better to CentOS 5 and to Mac OS X 10.6.
All calls to pipe2 changed.

Fixes: debbugs:14862

Fix the introduction of `set-frame-selected-window''s arguments.

* doc/lispref/windows.texi (Selecting Windows): Fix the introduction of `set-frame-selected-window''s arguments.

Prefer list1 (X) to Fcons (X, Qnil) when building lists.

This makes the code easier to read and the executable a bit smaller.
Do not replace all calls to Fcons that happen to create lists,
just calls that are intended to create lists.  For example, when
creating an alist that maps FOO to nil, use list1 (Fcons (FOO, Qnil))
rather than list1 (list1 (FOO)) or Fcons (Fcons (FOO, Qnil), Qnil).
Similarly for list2 through list5.

* xmenu.c (Fx_popup_dialog, xmenu_show, xdialog_show)
(menu_help_callback, xmenu_show):
* xml.c (make_dom):
* xterm.c (set_wm_state):
Prefer list1 (FOO) to Fcons (FOO, Qnil) when creating a list,
and similarly for list2 through list5.

Spelling fixes for "does not exists".

* lisp/edmacro.el (edmacro-format-keys): Fix previous change.

* callproc.c (Fcall_process_region): Fix minor race and tune.

(create_temp_file): New function, with the temp-file-creation part
of the old Fcall_process_region.  Use Fcopy_sequence to create the
temp file name, rather than alloca + build_string, for simplicity.
Don't bother to block input around the temp file creation;
shouldn't be needed.  Simplify use of mktemp.  Use
record_unwind_protect immediately after creating the temp file;
this closes an unlikely race where the temp file was not removed.
Use memcpy rather than an open-coded loop.
(Fcall_process_region): Use the new function.  If the input is
empty, redirect from /dev/null rather than from a newly created
empty temp file; this avoids unnecessary file system traffic.

* shell.el (explicit-bash-args): Remove obsolete hack for Bash 1.x.

The hack didn't work outside English locales anyway.

lisp/simple.el (define-alternatives): Rename from alternatives-define.

lisp/desktop.el (desktop-restore-frames): Change default to t.
(desktop-restore-in-current-display): Now offer more options.

desktop--excluded-frame-parameters.
(desktop--target-display): New variable.
(desktop-switch-to-gui-p, desktop-switch-to-tty-p, desktop--filter-tty*)
(desktop--filter-*-color, desktop--filter-minibuffer)
(desktop--filter-restore-desktop-parm, desktop--filter-save-desktop-parm)
(desktop-restore-in-original-display-p): New functions.
(desktop--filter-frame-parms): Use new desktop-filter-parameters-alist.
(desktop--save-minibuffer-frames): New function, inspired by a similar
function from Martin Rudalics.
(desktop--save-frames): Call it; play nice with desktop-globals-to-save.
(desktop--restore-in-this-display-p): Remove.
(desktop--find-frame): Rename from desktop--find-frame-in-display and add
predicate argument.
(desktop--make-full-frame): Remove, integrated into desktop--make-frame.
(desktop--reuse-list): New variable.
(desktop--select-frame, desktop--make-frame, desktop--sort-states):
New functions.
(desktop--restore-frames): Add support for "minibuffer-special" frames.

* filelock.c (create_lock_file) [!HAVE_MKOSTEMP && !HAVE_MKSTEMP]:

Simplify by making this case like the other two.  This is a bit
slower on obsolete hosts, but the extra complexity isn't worth it.

* net/tramp-sh.el (tramp-sh-handle-vc-registered): Use `ignore-error'.

Spelling fixes.

* callproc.c (child_setup, relocate_fd) [!DOS_NT]:

* process.c (create_process) [!DOS_NT]:
Remove now-unnecessary calls to emacs_close.

* lisp/progmodes/ruby-mode.el (ruby-font-lock-keywords): Highlight
conversion methods on Kernel.

progmodes/cc-engine.el (c-forward-decl-or-cast-1): Label CASE 13
and comment it out.  This out-commenting enables certain C++
declarations to be parsed correctly.

Prevent leak in GDI objects (bug #14850).

 src/w32term.c (x_draw_hollow_cursor): Delete the brush object when
 returning early.

Improve the documentation of prefer-utf-8 and related issues.

 lisp/international/mule.el (define-coding-system): Doc fix.

 etc/NEWS: Document prefer-utf-8 coding-system and the new attributes
 :inhibit-null-byte-detection, :inhibit-iso-escape-detection, and
 :prefer-utf-8.

Fix bug #14822 with decoding when inhibit-null-byte-detection is non-nil.

 src/coding.c (syms_of_coding): Set up inhibit-null-byte-detection
 and inhibit-iso-escape-detection attributes of 'undecided'.

Auto-commit of generated files.

* deps.mk (sysdep.o): Remove dependency on ../lib/ignore-value.h.

Reported by Herbert J. Skuhra in
<http://lists.gnu.org/archive/html/emacs-devel/2013-07/msg00455.html>.

Fix bug #14838 with slow scrolling with certain fonts.

 lisp/simple.el (default-font-height): Don't call font-info if the
 frame's default font didn't change since the frame was created.

* ido.el (ido-read-file-name): Guard against non-symbol value.

* lisp/progmodes/python.el (python-imenu--build-tree): Fix corner case
in nested defuns.

* test/automated/python-tests.el (python-imenu-create-index-2)
(python-imenu-create-index-3): New tests.

* NEWS: Mention new value for ido-use-virtual-buffers.

* ido.el (ido-exhibit): Handle ido-enter-matching-directory before
ido-set-matches call.

Fixes: debbugs:6852

Don't lose top specpdl entry when memory is exhausted.

* eval.c (grow_specpdl): Increment specpdl top by 1 and check for
specpdl overflow here, to simplify callers; all callers changed.
Always reserve an unused entry at the stack top; this avoids
losing the top entry's information when memory is exhausted.

* configure.ac: Simplify --with-file-notification handling.

ChangeLog fix

* progmodes/ruby-mode.el (ruby-font-lock-keywords): Simplify the last
  change.

* configure.ac: Further fix.

* configure.ac: Fix goofs in previous.

* lisp/progmodes/ruby-mode.el (ruby-percent-literals-beg-re):
(ruby-syntax-expansion-allowed-p): Support array of symbols, for
Ruby 2.0.
(ruby-font-lock-keywords): Distinguish calls to functions with
module-like names from module references.  Highlight character
literals.

Fix last lisp/ChangeLog entry.

Fixes: debbugs:14847

Fix bug #14847 with continued GDB command lines in gdb-mi.el.

 lisp/progmodes/gdb-mi.el (gdb-strip-string-backslash): New function.
 (gdb-send): Handle continued commands.

* configure.ac: If with-file-notification=yes, if gfile not found,
go on to try inotify (not on MS Windows or Nextstep).

* etc/NEWS: Copyedits.

Clean up errno reporting and fix some errno-reporting bugs.

* callproc.c (Fcall_process):
* fileio.c (Fcopy_file, Finsert_file_contents, Fwrite_region):
* process.c (create_process, Fmake_network_process):
* unexaix.c (report_error):
* unexcoff.c (report_error):
Be more careful about reporting the errno of failed operations.
The code previously reported the wrong errno sometimes.
Also, prefer report_file_errno to setting errno + report_file_error.
(Fcall_process): Look at openp return value rather than at path,
as that's a bit faster and clearer when there's a numeric predicate.
* fileio.c (report_file_errno): New function, with most of the
old contents of report_file_error.
(report_file_error): Use it.

Set errno to 0 when it is junk.
* fileio.c (Faccess_file):
* image.c (x_create_bitmap_from_file):
Use faccessat rather than opening the file, to avoid the hassle of
having a file descriptor open.
* lisp.h (report_file_errno): New decl.
* lread.c (Flocate_file_internal): File descriptor 0 is valid, too.

Minor EBADF fixes.

* process.c (create_process, wait_reading_process_output) [AIX]:
Remove obsolete SIGHUP-related  code, as Emacs no longer disables
SIGHUP, so EBADF is no longer acceptable here (it wouldn't work in
a multithreaded environment anyway).
* sysdep.c (emacs_close): It's not dangerous to invoke emacs_close (-1).

lisp/desktop.el: Minor fixes.
(desktop--v2s): Remove unused local variable.
(desktop-save-buffer): Make defvar-local; adjust docstring.
(desktop-auto-save-timeout, desktop-owner): Use ignore-errors.

* image.c (x_find_image_file): Don't close a remote file handle.

Minor followup to previous commit.

 lisp/simple.el (next-line, previous-line): Document TRY-VSCROLL and ARG.

Fixes: debbugs:14842

Fix bug #14842 with doc strings of next-line and previous-line.

 lisp/simple.el (next-line, previous-line): Document TRY-VSCROLL.

Use emacs_close, not close.
* src/sysdep.c (POSIX_CLOSE_RESTART, posix_close) [!POSIX_CLOSE_RESTART]:
New macro and function, which emulates the POSIX_CLOSE_RESTART macro
and posix_close function on current platforms (which all lack them).
(emacs_close): Use it.  This should fix the races on GNU/Linux and
on AIX and on future platforms that support POSIX_CLOSE_RESTART,
and it should avoid closing random victim file descriptors on
other platforms.
