* emacsclient.c (xmalloc): Accept size_t, not unsigned int, to
avoid potential buffer overflow issues on typical 64-bit hosts.
Return void *, not long *.
(get_current_dir_name): Report a failure, instead of looping
forever, if buffer size calculation overflows. Treat malloc
failures like realloc failures, as that has better behavior and is
more consistent. Do not check whether xmalloc returns NULL, as
that's not possible.
(message): Do not arbitrarily truncate message to 2048 bytes when
sending it to stderr; use vfprintf instead.
(get_server_config, set_local_socket)
(start_daemon_and_retry_set_socket): Do not alloca
arbitrarily-large buffers; that's not safe.
(get_server_config, set_local_socket): Do not use sprintf when its
result might not fit in 'int'.
(set_local_socket): Do not assume uid fits in 'int'.
* doc/emacs/package.texi: New file, documenting the package manager.
* doc/emacs/emacs.texi: Include it.
* doc/emacs/help.texi (Help Summary): Add describe-package.
* doc/emacs/display.texi (Narrowing): Move into display chapter.
* doc/emacs/picture-xtra.texi (Picture Mode): Group with Editing Binary
Files section. Convert from chapter into section.
* doc/emacs/text.texi (Two-Column): Move into Text chapter.
src/xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
the display spec is of the form `(space ...)'.
(handle_display_spec): Return the value returned by
handle_single_display_spec, not just 1 or zero.
(handle_single_display_spec): If the display spec is of the form
`(space ...)', and specifies display in the text area, return 2
rather than 1.
src/dispextern.h (struct bidi_it): Rename the disp_prop_p member
into disp_prop; all users changed.
src/bidi.c (bidi_fetch_char): If compute_display_string_pos returns
DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
for the text covered by the display property.
lisp/buff-menu.el (Buffer-menu-buffer+size): Remove calls to
bidi-string-mark-left-to-right; they are unnecessary now.
doc/lispref/display.texi (Specified Space): Mention that `space' specs
influence bidi reordering.
(Bidirectional Display): Explain how to use `(space . PROPS)' for
separating fields with bidirectional content.
* lisp/battery.el (battery-update): Use the face `error' instead of
`font-lock-warning-face'.
* lisp/ibuffer.el (ibuffer-marked-face): Change default face from
`font-lock-warning-face' to `warning'.
(ibuffer-deletion-face): Change default face from
`font-lock-type-face' to `error'.
* lisp/proced.el (proced-marked): Inherit from `error' instead of
`font-lock-warning-face'.
Fixes: debbugs:6117
* lisp/window.el (quit-window): Renamed from quit-restore-window. Use
same arglist as old quit-window.
(frame-auto-delete): Doc fix.
* lisp/view.el (view-mode-exit): Use quit-window.
src/xdisp.c (set_cursor_from_row): Consider candidate row a win if its
glyph represents a newline and point is on that newline. Fixes cursor
positioning on the newline at EOL of R2L text within L2R
paragraph, and vice versa.
(try_cursor_movement): Check continued rows, in addition to
continuation rows. Fixes unwarranted scroll when point enters a
continued line of R2L text within an L2R paragraph, or vice versa.
(cursor_row_p): Consider the case of point being equal to
MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
from the end of a short line to the beginning of a continued line
of R2L text within L2R paragraph.
(RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
composed characters.
src/xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
buffers, return left-to-right.
doc/lispref/display.texi (Bidirectional Display): Document return value in
buffers that are not bidi-reordered for display, and in unibyte
buffers.
* lisp/isearch.el (isearch-ring-adjust1): Start visiting previous
search strings from the index 0 (-1 + 1) instead of 1 (0 + 1).
(isearch-repeat, isearch-edit-string): Call `isearch-ring-adjust1'
for empty search string (when the last search string is reused
automatically) to adjust the isearch ring to the last element and
prepare the correct index for further M-p commands.
Fixes: debbugs:9185
from process filters aren't reliably transmitted to the surrounding
accept-process-output.
(mpc-proc-check): New function.
(mpc-proc-sync): Use it
Fixes: debbugs:8293
src/bidi.c (bidi_get_type): Abort if we get zero as the bidi type of
a character.
admin/unidata/unidata-gen.el (unidata-prop-alist): Update the default
values of bidi-class according to DerivedBidiClass.txt from the
latest UCD.
lisp/international/uni-bidi.el: Regenerated.
doc/lispref/nonascii.texi (Character Properties): Document the values for
unassigned codepoints.
src/dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
instead of CHAR_TO_BYTE. Fixes a crash when a completion
candidate is selected by the mouse, and that candidate has a
composed character under the mouse.
