This speeds up building of documentation on multiprocessor
platforms, and is motivated by Texinfo 5.0, which is much slower.
Add a toplevel rule 'make docs' to make all the documentation.
* .bzrignore: Add .dvi, .html, .ps.
* Makefile.in (DVIS, HTMLS, INFOS, PSS, DOCS): New macros.
($(DOCS), docs, vi, html, pdf, ps): New rules.
(info-real): Depend on $(INFOS) rather than doing it sequentially.
(dvi): Depend on $(DVIS) rather than doing it sequentially.
* doc/misc/Makefile.in (html): New rule.
* configure.ac (DATA_START, DATA_SEG_BITS): Set to 0x20000000 on AIX.
(GC_MARK_STACK): Do not set to GC_USE_GCPROS_AS_BEFORE, as that
runs afoul of some other bug in Emacs, and the default value
GC_MAKE_GCPROS_NOOPS has been tested and works.
* src/lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
was #undeffed earlier, so it cannot be used as a macro here.
Use the constant and not the macro. Tested on AIX.
* src/unexaix.c: Revert 2013-02-11 and 2013-02-12 changes to this
file. They're almost surely OK but we're just before a release so
we should avoid changes unless they're clearly needed. Instead,
make the following minor change:
(ADDR_CORRECT): New macro.
Fixes: debbugs:13650
On my host, this speeds up directory-files-and-attributes by a
factor of 3, when applied to Emacs's src directory.
These functions are standardized by POSIX and are common these
days; fall back on a (slower) gnulib implementation if the host
is too old to supply them.
* .bzrignore: Add lib/dirent.h.
* lib/Makefile.am (libgnu_a_SOURCES): Add openat-die.c, save-cwd.c.
* lib/careadlinkat.c, lib/careadlinkat.h: Merge from gnulib,
incorporating: 2013-01-29 careadlinkat: do not provide careadlinkatcwd.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* lib/dirent.in.h, lib/fdopendir.c, lib/fstatat.c, lib/openat-priv.h:
* lib/openat-proc.c, lib/openat.h, m4/dirent_h.m4, m4/fdopendir.m4:
* m4/fstatat.m4: New files, from gnulib.
* lib/openat-die.c, lib/save-cwd.c, lib/save-cwd.h: New files.
These last three are specific to Emacs and are not copied from gnulib.
They are simpler than the gnulib versions and are tuned for Emacs.
* admin/merge-gnulib (GNULIB_MODULES): Add fdopendir, fstatat, readlinkat.
(GNULIB_TOOL_FLAGS): Do not avoid at-internal, openat-h.
Avoid dup, open, opendir.
* nt/inc/sys/stat.h (fstatat):
* nt/inc/unistd.h (readlinkat): New decls.
* src/conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
* src/dired.c: Include <fcntl.h>.
(open_directory): New function, which uses open and fdopendir
rather than opendir. DOS_NT platforms still use opendir, though.
(directory_files_internal, file_name_completion): Use it.
(file_attributes): New function, with most of the old Ffile_attributes.
(directory_files_internal, Ffile_attributes): Use it.
(file_attributes, file_name_completion_stat): First arg is now fd,
not dir name. All uses changed. Use fstatat rather than lstat +
stat.
(file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
* src/fileio.c: Include <allocator.h>, <careadlinkat.h>.
(emacs_readlinkat): New function, with much of the old
Ffile_symlink_p, but with an fd argument for speed.
It uses readlinkat rather than careadlinkatcwd, so that it
need not assume the working directory.
(Ffile_symlink_p): Use it.
* src/filelock.c (current_lock_owner): Use emacs_readlinkat
rather than emacs_readlink.
* src/lisp.h (emacs_readlinkat): New decl.
(READLINK_BUFSIZE, emacs_readlink): Remove.
* src/sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
(emacs_norealloc_allocator, emacs_readlink): Remove.
This stuff is moved to fileio.c.
* src/w32.c (fstatat, readlinkat): New functions.
(careadlinkat): Don't check that fd == AT_FDCWD.
(careadlinkatcwd): Remove; no longer needed.
Fixes: debbugs:13539

* doc/misc/calc.texi (Help Commands): Mention etc/CALC-NEWS.

(HAVE_GTK3): If above enable is off, add
-DGDK_DISABLE_DEPRECATION_WARNINGS to GTK_CFLAGS.
* configure.ac: Check for GtkHandlebox.
Check for GtkTearoffMenuItem.
* src/gtkutil.c (TOOLBAR_TOP_WIDGET): New macro.
(xg_pack_tool_bar): Use TOOLBAR_TOP_WIDGET, condition out use of
handlebox_widget. Set toolbar_in_hbox to false/true, set
toolbar_is_packed to true.
(xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
(update_frame_tool_bar): Check toolbar_is_packed for packing.
Show all on TOOLBAR_TOP_WIDGET.
(free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
by TOOLBAR_TOP_WIDGET.
(xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
Check toolbar_is_packed.
(xg_have_tear_offs, tearoff_remove, tearoff_activate): Condition on
HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
(xg_have_tear_offs): When ! HAVE_GTK_TEAROFF_MENU_ITEM_NEW, return
false.
(create_menus): Create tearoff only if HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
(xg_update_menubar): Update title only if
HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
(xg_update_submenu): Skip tearoff only if

handlebox_widget. Set toolbar_in_hbox to false/true, set
toolbar_is_packed to true.
(xg_update_tool_bar_sizes): Use widget returned by TOOLBAR_TOP_WIDGET.
(update_frame_tool_bar): Check toolbar_is_packed for packing.
Show all on TOOLBAR_TOP_WIDGET.
(free_frame_tool_bar): Check toolbar_is_packed. Use widget returned
by TOOLBAR_TOP_WIDGET.
(xg_change_toolbar_position): Use widget returned by TOOLBAR_TOP_WIDGET.
Check toolbar_is_packed.
* src/xterm.h (struct x_output): Surround handlebox_widget with
#ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,
toolbar_in_hbox is bool.
* configure.ac (TEMACS_LDFLAGS2): Don't define.
(LIBS_GNUSTEP): Set for GNUstep and substitute.
(LD_SWITCH_SYSTEM_TEMACS): Don't set for GNUstep.
* src/Makefile.in (TEMACS_LDFLAGS2): Remove.
(LIBS_GNUSTEP): Define.
(LIBES): Add $(LIBS_GNUSTEP).
(temacs$(EXEEXT)): Use $(LDFLAGS) instead of $(TEMACS_LDFLAGS2).

Use $@ rather than undocumented $ac_configure_args.
Replace any embedded double quotes.
Fixes: debbugs:13274
* configure.ac (WARN_CFLAGS): Omit -Wstack-protector when
configured with --enable-gcc-warnings. -Wstack-protector causes
diagnostics to be issued on Ubuntu 12.10 x86-64.
* configure.ac (acl): New option.
(HAVE_POSIX_ACL): Test for POSIX ACL support. This is typically
provided by libacl on GNU/Linux.
* fileio.c (Ffile_acl, Fset_file_acl): New functions.
(Fcopy_file): Change last arg to `preserve_extended_attributes'
and copy ACL entries of file in addition to SELinux context if
set.
(syms_of_fileio): Add `file-acl' and `set-file-acl'.
* Makefile.in (LIBACL_LIBS): New macro.
(LIBES): Use it.
* files.el (file-extended-attributes)
(set-file-extended-attributes): New functions.
(backup-buffer): Use them to handle both SELinux context and ACL
entries.
(backup-buffer-copy): Work with an alist of extended attributes,
rather than an SELinux context.
(basic-save-buffer-2): Ditto.
* files.texi (File Attributes): Document ACL support and new
`file-acl' function.
(Changing Files): Mention argument name change of `copy-file' and
document new function `set-file-acl'.
* configure.ac (BSD4_2): Remove; no longer needed.
* admin/CPP-DEFINES (BSD4_2): Remove.
* doc/lispintro/emacs-lisp-intro.texi (Files List):
directory-files-and-attributes now outputs t for attribute that's
now a placeholder.
* doc/lispref/files.texi (Testing Accessibility): Document GROUP arg
of file-ownership-preserved-p.
(File Attributes): Document that 9th element is now
just a placeholder.
* doc/lispref/os.texi (User Identification): Document new functions group-gid,
group-real-gid.
* etc/NEWS: Document changes to file-attributes,
file-ownership-preserved-p.
Mention new functions group-gid, group-real-gid.
* lisp/files.el (backup-buffer): Don't rely on 9th output of
file-attributes, as it's now a placeholder. Instead, use the new
optional arg of file-ownership-preserved-p.
(file-ownership-preserved-p): New optional arg GROUP.
Fix mishandling of setuid directories that would cause this
function to return t when it should have returned nil.
Document what happens if the file does not exist, and when
it's not known whether the ownership will be preserved.
* lisp/net/tramp-sh.el (tramp-sh-handle-file-ownership-preserved-p):
Likewise.
(tramp-get-local-gid): Use group-gid for integer, as that's
faster and more reliable.
* src/dired.c (Ffile_attributes): Return t as the 9th attribute,
to mark it as a placeholder. The old value was often wrong.
The only user of this attribute has been changed to use
file-ownership-preserved-p instead, with its new group arg.
* src/editfns.c (Fgroup_gid, Fgroup_real_gid): New functions.
