src/bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
some callers set that themselves.
src/xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
cursor motion with <left> and <right> arrow keys.
* configure.in (GC_LISP_OBJECT_ALIGNMENT): Remove.
This is now done by src/alloc.c.
* src/alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
this makes Emacs dump core during garbage collection on rare
occasions. sizeof is obviously inferior to offsetof here, so
stick with offsetof.
(GC_POINTER_ALIGNMENT): New macro.
(mark_memory): Omit 3rd (offset) arg; caller changed.
Don't assume EMACS_INT alignment is the same as pointer alignment.
(pcomplete--common-suffix): Remove.
(pcomplete--common-quoted-suffix): Use comint--common-suffix instead.
(pcomplete--table-subvert): Sync with comint--table-subvert.
(pcomplete--entries): Use comint-completion-file-name-table.
* lisp/comint.el (comint-unquote-filename): Simplify.
(comint-completion-file-name-table): New function.
(comint--complete-file-name-data): Use it.
* src/dired.c (file_name_completion): Don't expand file name.
(Ffile_name_completion, Ffile_name_all_completions): Expand file name
before checking file name handler.
Fixes: debbugs:9616
This fixes a Y2038 bug on 64-bit hosts.
* buffer.c (reset_buffer):
* fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
(Fclear_buffer_auto_save_failure):
Use 0, not -1, to represent an unset failure time, since time_t
might not be signed.
* alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
Move back here from lisp.h, but with their new implementations.
(XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
(XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
* charset.c (charset_table_init): New static var.
(syms_of_charset): Use it instead of xmalloc. This removes a
dependency on glibc malloc internals. See Eli Zaretskii's comment in
<http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
* lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
Move back to alloc.c.
(XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
(XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
* alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
Move to lisp.h.
(xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
(overrun_check_realloc, overrun_check_free):
Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
That way, xmalloc returns a properly-aligned pointer even if
XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
* charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
into account when calculating the initial malloc maximum.
* lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
Move here from alloc.c, so that charset.c can use it too.
Properly align; the old code wasn't right for common 32-bit hosts
when configured with --enable-checking=all.
(XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
(XMALLOC_OVERRUN_SIZE_SIZE): New macros.
msdos/mainmake.v2 (boot): Condition the value on the existence of
autogen/README, not admin/admin.el, since the latter is now part
of the release tarball.
(install): Don't copy lib-src/fns.el, as that file is no longer
generated in that directory.
msdos/sed1v2.inp (LIB_PTHREAD, LIB_PTHREAD_SIGMASK): Edit to empty.
(SETTINGS_CFLAGS, SETTINGS_LIBS): Edit these instead of
GCONF_CFLAGS and GCONF_LIBS.
msdos/sedlibmk.inp (ALLOCA_H, AR, ARFLAGS, GNULIB_CHDIR, GNULIB_DUP)
(GNULIB_FDATASYNC, GNULIB_FDOPEN, GNULIB_FSTAT, GNULIB_PCLOSE)
(GNULIB_PTHREAD_SIGMASK, GNULIB_RAISE, GNULIB_SIGACTION)
(GNULIB_SIGPROCMASK, GNULIB_SIGNAL_H_SIGPIPE, HAVE_FDATASYNC)
(HAVE_PCLOSE, HAVE_POPEN, HAVE_POSIX_SIGNALBLOCKING)
(HAVE_PTHREAD_SIGMASK, HAVE_RAISE, HAVE_SIGACTION)
(HAVE_SIGHANDLER_T, HAVE_SIGINFO_T, HAVE_SIGSET_T)
(HAVE_STRUCT_SIGACTION_SA_SIGACTION)
(HAVE_TYPE_VOLATILE_SIG_ATOMIC_T, LIB_PTHREAD)
(LIB_PTHREAD_SIGMASK, NEXT_AS_FIRST_DIRECTIVE_SIGNAL_H)
(NEXT_SIGNAL_H, REPLACE_FDOPEN, REPLACE_PTHREAD_SIGMASK)
(REPLACE_RAISE): New edits.
(gl_LIBOBJS): Remove md5.o, filemode.o, and sha1.o. Add
pthread_sigmask.o.
(@GL_GENERATE_ALLOCA_H_TRUE@, @GL_GENERATE_ALLOCA_H_FALSE@): Edit
to comment out unneeded lines.
(warn-on-use.h): Edit the recipe commands to work with DJGPP
without requiring a Unixy shell.
msdos/inttypes.h (strtoimax) [DJGPP < 2.04]: New macro.
msdos/sed2v2.inp (HAVE_ALLOCA, HAVE_DECL_STRTOLL, HAVE_DECL_STRTOIMAX)
(HAVE_STRTOLL, HAVE_SIGSET_T, HAVE_SNPRINTF): New edits.
.bzrignore: Add ./GNUMakefile.unix.
config.bat: Rename GNUMakefile, so it is not run on MS-DOS.
Rename signal.in.h and alloca.in.h.
src/sysdep.c (snprintf) [EOVERFLOW]: If EOVERFLOW is not defined,
use EDOM.
src/xdisp.c (compute_display_string_end): If there's no display
string at CHARPOS, return -1.
src/bidi.c (bidi_fetch_char): When compute_display_string_end
returns a negative value, treat the character as a normal
character not covered by a display string.
src/xdisp.c (handle_invisible_prop): If invisible text ends on a
newline, reseat the iterator instead of bidi-iterating there one
character at a time. (Bug#9610)
(BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
TO_CHARPOS if the bidi iterator is at base embedding level.
src/dispnew.c (syms_of_display) <redisplay-dont-pause>: Default
value is now t. Doc fix.
doc/lispref/display.texi (Forcing Redisplay): Update the description of
redisplay-dont-pause due to change in the default value.
etc/NEWS: Mention the change of the default value.
src/indent.c (Fvertical_motion): Compute and apply the overshoot
logic when moving up, not only when moving down. Fix the
confusing name and values of the it_overshoot_expected variable;
logic changes accordingly. (Bug#9254) (Bug#9549)
src/xdisp.c (pos_visible_p): Produce correct pixel coordinates when
CHARPOS is covered by a display string which includes newlines.
(move_it_vertically_backward): Avoid inflooping when START_CHARPOS
is covered by a display string with embedded newlines.
The previous change was incomplete.
While it makes emacs --batch detect the vast majority of stdout
write failures, errors were still ignored whenever the output size is
k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
$ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
&& echo FAIL: ignored write error
FAIL: ignored write error
$ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
&& echo FAIL: ignored write error
FAIL: ignored write error
* emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
src/xdisp.c (pop_it): Allow it->object that is a cons cell to pass
the xassert test.
src/dispextern.h (struct it): Update the comment documenting what
can it->OBJECT be.
