This member has little value even on X, and it leaks internal backend
details to the glyph_string struct.
* src/dispextern.h (glyph_string): Remove X display member.
* src/xdisp.c (init_glyph_string): Remove initialization of display.
* src/xfont.c (xfont_draw):
* src/xterm.c: Use FRAME_X_DISPLAY (s->f) instead of display member.
If you do `C-h k ... mouse-1 in other frame` (at least if you have a focus
that follows the mouse), then additionally to the down-mouse-1 and mouse-1
events, a `switch-frame` event (and `select-window` event as well sometimes)
is generated. When `read-key-sequence` is called with nil for
`can-return-switch-frame`, this event is not returned but kept for later,
which causes a subsequent `sit-for` to return nil immediately.
This interfered without our "wait for double-click" which in turn prevented
us from stopping after the mouse-1 click, getting stuck waiting for something
else instead.
(help--read-key-sequence): Pass a non-nil `can-return-switch-frame`, so the
subsequent `sit-for` returns more trustworthy information.
In 2016-02-14 "Remove compat code for older Emacsen",
message-default-charset was obsoleted, and a couple of uses were
removed, but others were left behind.
* lisp/gnus/message.el (message-send-mail)
(message-send-news, message-do-fcc)
(message-encode-message-body):
* lisp/gnus/mml.el (mml-to-mime): Stop using message-default-charset.
This is mainly by enhancing a parse-partial-sexp cache to retain recently
calculated values. Also, there are several miscellaneous optimizations and
bug fixes.
* lisp/progmodes/cc-engine.el (c-state-semi-nonlit-near-cache): New buffer
local variable.
(c-state-semi-trim-near-cache, c-state-semi-get-near-cache-entry)
(c-state-semi-put-near-cache-entry, c-state-semi-trim-cache): New functions.
(c-state-semi-pp-to-literal, c-state-full-pp-to-literal): Use the new "near"
cache.
(c-parse-ps-state-below): Use the new function c-state-semi-trim-cache.
(c-before-change-check-<>-operators): Check simply for < or > in the
neighbourhood before doing more expensive processing.
(c-maybe-re-mark-raw-string): Give a backward search limit to an operation
which was needlessly lacking one.
* lisp/progmodes/cc-mode.el (c-doc-fl-decl-start, c-doc-fl-decl-end): Check a
certain regexp is valid before performing the (somewhat expensive) actions of
these functions.
(c-fl-decl-start): In the search for a C++ lambda capture list, replace (slow)
calculation of c-parse-state by a (less slow) c-go-up-list-backward.
These spaces were typically inserted earlier by comment-region. This patch
makes these two complementary functions closer to inverses.
* lisp/newcomment.el (uncomment-region-default-1): Remove spaces before a tab
where the comment opener has just been removed.
(syntax-ppss-after-change-function): Mark it as obsolete.
* lisp/font-lock.el (font-lock-apply-syntactic-highlight):
Use syntax-ppss-flush-cache instead.
* src/image.c (LIBRSVG_CHECK_VERSION): Define to yield false
if it isn’t already defined.
(svg_load_image): Port to C preprocessors that check the
syntax of the entire preprocessing expression before
evaluating any of it.
* lisp/emacs-lisp/eieio-base.el (clone): Unbound slots of
eieio-instance-inheritor objects as documented in the docs string
and implemented in the original eieio implementation.
* src/xdisp.c (display_mode_element): Add an assertion where
we assume that 'string' returned by decode_mode_spec is always
either a Lisp string or nil.
* src/intervals.c (set_intervals_multibyte_1): Omit unused temps.
* src/xdisp.c (display_mode_element): Use !NILP instead of
STRINGP. This convinces GCC we’re not dereferencing a
possibly-null pointer, and should be a bit faster anyway.
The start and end lines of the scroll region must to be in the range
[0,term-height). There are few placees that incorrectly set the end
line of the scroll region to term-height which is outside the valid
range. Combined with another off-by-one error in
term-set-scroll-region's clamping logic, this would cause
term-scroll-with-delete to be unnecessarily turned on.
* lisp/term.el (term-scroll-start,term-scroll-end): Use defvar-local
to define the variables and document the valid range of values that
the variables can take.
(term--last-line): New function to calculate the 0-based index of the
last line.
(term--reset-scroll-region): New function to reset the scroll region
to the full height of the terminal.
(term-mode,term-reset-size,term-reset-terminal): Call
term--reset-scroll-region to reset the scroll region.
(term-set-scroll-region): Fix the off-by-one error in the clamping
logic which allowed term-scroll-end to have values outside the valid
range [0,term-height).
This assertion was removed in 1c349c6230
because the assumption was invalid during set_intervals_multibyte_1.
So we change set_intervals_multibyte_1 to solve the problem in the same
way as in the rest of Fset_buffer_multibyte, which actually simplifies
the code.
* src/buffer.c (advance_to_char_boundary): Not static any more.
* src/buffer.h (advance_to_char_boundary): Add prototype.
* src/intervals.c (set_intervals_multibyte_1): Use it.
* doc/lispref/commands.texi (Input Events): Specify that events are
non-nil and remove vestiges of bug#10190.
* doc/lispref/os.texi (Recording Input): Document optional argument
of recent-keys.
* lisp/subr.el (eventp): Check that the car of conses is non-nil.
* etc/NEWS: Announce it as an incompatible change.
* src/keyboard.c (Frecent_keys): Clarify that returned "events" are
not real events.
* lisp/term.el (term-unwrap-line, term-emulate-terminal): Prevent the
`term-line-wrap` property of newlines from spreading accidentally
when inserting text next to it.
* lisp/progmodes/cc-engine.el (c-beginning-of-statement-1): The variable
before-sws-pos should record the position of a closing paren/brace/bracket
before moving backwards over a sexp. When there is a syntactic WS macro
between the starting point and the closing p/b/b, setq before-sws-pos again
after moving backward over the macro.
Avoid the abuse of (eval `(defvar ...)) which tends to end up
adding redundant entries in `load-history`, as discussed in
https://lists.gnu.org/r/help-gnu-emacs/2019-03/msg00237.html
(custom-initialize-default): Don't add to load-history.
(custom-declare-variable): Use internal--define-uninitialized-variable
and only add the var to load-history once. Do it before calling
`initialize` so the special-variable-p flag is set.
* src/eval.c (Finternal__define_uninitialized_variable): New function.
(Fdefvar, Fdefconst): Use it.
(syms_of_eval): Defsubr' it.
The module code can’t possibly work on weird platforms where
function pointers are wider than data pointers, so there’s no need
to bother with the stackoverflow-like approach that is intended
only for portability to such platforms. Besides, the
stackoverflow-like approach does not work well on weird platforms
where CHAR_BIT is not a multiple of 4.
* src/lisp.h (pMx): New macro.
* src/print.c (data_from_funcptr) [HAVE_MODULES]: New function.
(print_vectorlike) [HAVE_MODULES]: Use it.
(print_object): Make sure buf is big enough for this.
Strip possible source/destination prefixes such as a/ and b/
from directory names. (Bug#35420)
(ediff-fixup-patch-map, ediff-dispatch-file-patching-job)
(ediff-patch-file-internal): Replace string-match with string-match-p.
* lisp/dired-aux.el (dired-map-over-marks-check): Use ngettext
instead of dired-plural-s.
(dired-create-files): Also add colon after operation name.
(dired-compare-directories): Use ngettext and format-message.
(dired-do-compress-to): Use ngettext.
* lisp/dired.el (dired-internal-do-deletions)
(dired-clean-up-after-deletion): Use ngettext instead of dired-plural-s.
* test/data/emacs-module/mod-test.c (NDEBUG): Undef, to prevent
GCC from complaining “error: unused variable ‘dummy’” and failing
to build the test, if --enable-gcc-warnings.
