* src/bidi.c (bidi_resolve_weak): Avoid entering a loop searching
for a character needed for resolving the type of a series of BN
and ET characters, as required by rule W5 of UAX#9, if the results
of the resolution are known in advance, because we are at level
zero, and the previous strong character was L.
(bidi_resolve_neutral): Partially resurrect the optimization for a
long series of control characters in an otherwise strictly L2R
text.
(bidi_level_of_next_char): Don't enter the loop that searches for
a paragraph separator if the current character is already at base
embedding level. (Bug#22739)
* src/bidi.c (bidi_resolve_explicit): Override the orig_type value
of FSI with either LRI or RLI, as determined by the first strong
directional character in the isolate. This prevents failure to
isolate when the FSI...PDI text is inside a directional override.
(Bug#22786)
* src/xftfont.c (xftfont_open): Remove "dirty workaround" for
XftTextExtents8 behavior, as it is no longer needed. Suggested by
Fangwen Yu <yynyygy@gmail.com>. (Bug#22383)
* src/keyboard.c (read_key_sequence): Don't inadvertently set
immediate_echo when we don't want any echo-keystrokes.
(echo_keystrokes_p): Move earlier.
* src/w32heap.c (mmap_alloc): Reserve memory in 64KB granular
units. This avoids leaving gaps in reserved memory regions that
no one can use, since memory reservation must produce 64KB-aligned
addresses. (Bug#22526)
This tries to port to x86 FreeBSD 9, where Emacs dumps core (Bug#22065).
* src/lisp.h (USE_STACK_LISP_OBJECTS): Default to false
for GCC 4.3.1 and earlier.
* src/w32heap.c (mmap_alloc): If reserving memory succeeds, but
committing fails, return NULL. Don't call GetLastError twice for
the same API error.
(mmap_realloc): Zero out MEMORY_BASIC_INFORMATION structures
before calling VirtualQuery, to avoid using garbled values if the
call fails. If committing more pages from the same block fails,
fall back on mmap_alloc + CopyMemory. Enhance debugging printouts
if the call to VirtualAlloc to commit more pages fails.
(Bug#22526)
Fedora 23 normally hardens GNUstep applications, which causes
‘./configure --with-ns’ to break Emacs’s funky way of undumping.
Fix this by eliding the hardening options (Bug#22518).
* src/Makefile.in (LIBS_GNUSTEP): Omit options like
‘-specs=/usr/lib/rpm/redhat/redhat-hardened-ld’.
(GNU_OBJC_CFLAGS): Omit options like
‘-specs=/usr/lib/rpm/redhat/redhat-hardened-cc1’.
* lisp/simple.el (backward-word): Refer to 'backward-word-strictly'
in the doc string. Suggested by Glenn Morris <rgm@gnu.org>.
* lisp/subr.el (forward-word-strictly, backward-word-strictly):
Mention 'subword-mode' in the doc strings.
* src/syntax.c (Fforward_word): Refer to 'forward-word-strictly'
in the doc string. (Bug#22560)
* src/image.c (imagemagick_load_image): Allow integer rotations in
addition to floating point rotations (bug#22591).
* src/image.c (imagemagick_load_image): Images that have an
orientation given in EXIF and have no explicit :rotation tag are now
pre-rotated. All information such as width/height is reported for the
rotated image.
Without this patch, some ACL operations were suppressed, but not all.
* src/fileio.c [!USE_ACL]: Do not include sys/acl.h.
(Ffile_acl, Fset_file_acl) [!USE_ACL]: Return nil in this case.
* src/alloc.c (lmalloc, lrealloc): Reallocate with (typically)
larger and larger sizes, to increase the probability that
the allocator will return a Lisp-aligned pointer.
Problem reported by Herbert J. Skuhra in:
http://lists.gnu.org/archive/html/emacs-devel/2016-02/msg00354.html
Instead of trying
* src/alloc.c (lmalloc, lrealloc, laligned): New functions.
(xmalloc, xzalloc, xrealloc, lisp_malloc): Use them.
(__alignof__) [!__GNUC__ && !__alignof__]: New macro.
(MALLOC_IS_GC_ALIGNED): New macro.
* src/lisp.h (NONPOINTER_BITS): Remove. All uses removed.
No longer needed now that alloc.c uses lmalloc and lrealloc.
* src/process.c (conv_lisp_to_sockaddr): AF_INET6 addresses are
converted to a list of 16 bit quantities by
conv_sockaddr_to_lisp(). conv_lisp_to_sockaddr() should follow the
same scheme rather than expecting a (longer) list of 8 bit
quantities.
Backport:
(cherry picked from commit 55ce3c30d6)
* src/xfns.c (compute_tip_xy): Use the resolution of the monitor where
the mouse pointer is to avoid placing the tooltip over the border of
the monitor on multi-head displays. Fixes bug#22549.
* src/w32inevt.c (handle_file_notifications): Count the number of
events to be returned.
* src/w32notify.c (send_notifications): Don't copy to the file
notification buffer more than it can hold. (Bug#22534)
* doc/lispref/buffers.texi (Read Only Buffers): Describe optional
argument POSITION.
* doc/lispref/debugging.texi (Error Debugging): `debug-on-signal'
is an option.
* doc/lispref/display.texi (Refresh Screen): Describe optional
argument FRAME of `redraw-frame'.
(Attribute Functions): Describe optional argument CHARACTER of
`face-font'.
(Defining Images): `image-load-path' is an option.
(Beeping): `ring-bell-function' is an option.
* doc/lispref/frames.texi (Size and Position): The PIXELWISE
argument of `set-frame-size' is optional.
(Raising and Lowering): The TERMINAL argument of `tty-top-frame'
is optional.
* doc/lispref/keymaps.texi (Controlling Active Maps): Fix doc of
`set-transient-map'.
* doc/lispref/minibuf.texi (Text from Minibuffer):
`read-regexp-defaults-function' is an option.
(Minibuffer Contents): `delete-minibuffer-contents' is a command.
* doc/lispref/modes.texi (Mode Line Variables):
`mode-line-position' and `mode-line-modes' are variables, not
options.
* doc/lispref/strings.texi (Creating Strings): The START argument
of `substring' is optional.
* doc/lispref/text.texi (Buffer Contents): Describe optional
argument NO-PROPERTIES of `thing-at-point'.
(User-Level Deletion): Both arguments of
`delete-trailing-whitespace' are optional.
(Margins): Use @key{RET} instead of @kbd{RET}.
* doc/lispref/windows.texi (Display Action Functions): Write
non-@code{nil} instead of non-nil.
(Choosing Window Options): The WINDOW arg of
`split-window-sensibly' is optional.
(Choosing Window Options): Write non-@code{nil} instead of
non-nil.
(Window Start and End): Both args of `window-group-end' are
optional.
* src/buffer.c (Fbarf_if_buffer_read_only): Rename argument POS
to POSITION to keep consisteny with doc-string.
* src/keyboard.c (handle_interrupt): Fix recently-introduced
typo (040 should have been ~040) that silently suppressed
auto-saves after emergency escapes. Redo comparison to avoid
similar problems.
Without this change, with --enable-gcc-warnings GCC would complain
“error: redundant redeclaration of ‘aligned_alloc’”.
* configure.ac: Simplify aligned_alloc testing.
* src/alloc.c (aligned_alloc): Don’t use if DARWIN_OS,
since the simplified configure.ac no longer checks for that.
Don’t declare if HAVE_ALIGNED_ALLOC.
Correct misspelling of HAVE_ALIGNED_ALLOC in ifdef.
