* src/comp.c (comp_hash_source_file): Condition code that requires
zlib with HAVE_ZLIB.
* etc/NEWS: Explain that '--without-compress-install' is necessary
when configuring with native compilation but without zlib.
* src/eval.c: Remove an outdated comment about protection from GC.
* src/buffer.h:
* src/lisp.h: Add warnings about using 'char *' pointers to text
of Lisp strings and buffer text in code that could GC. Reported by
Po Lu <luangruo@yahoo.com>
* src/search.c (Freplace_match): Speed up non-literal (but
actually literal) common case.
This makes
(benchmark-run 1000000
(replace-regexp-in-string
"a+" "foo"
"ogihdipofdhookfdohkfdpokhpokhfdpokfdhpokfdhkdfkhgoadfphokfkhpofdkhkdpokf"))
about 10% faster.
This covers both sequences using Zero-Width-Joiner codepoints and
those without. Bug#39799, I hope.
* .gitignore: Add emoji-zwj.el
* admin/notes/unicode: Add emoji-zwj-sequences.txt and
emoji-sequences.txt references. Describe how to test after updating
to a newer Unicode version.
* admin/unidata/Makefile.in (all): add emoji-zwj.el as a dependency.
(emoji-zwj.el): Add target plus rules for building.
(gen-clean): Add emoji-zwj.el.
* admin/unidata/README: Add emoji-zwj-sequences.txt and
emoji-sequences.txt references.
* admin/unidata/blocks.awk: Force emoji script to be used for certain
codepoints that are used by the Unicode sequences.
* admin/unidata/emoji-sequences.txt: New file.
* admin/unidata/emoji-zwj-sequences.txt: New file.
* admin/unidata/emoji-zwj.awk: New file. Derives
composition-function-table rules from emoji-zwj-sequences.txt, plus
hardcodes some derived manually from emoji-sequences.txt.
* etc/NEWS: Announce change.
* lisp/international/characters.el: Load the generated emoji-zwj.el
* src/Makefile.in (emoji-zwj): New target.
(temacs): Add emoji-zwj as a dependency.
* doc/lispref/commands.texi (Recursive Editing): Mention what happens
when throwing a string or any other value to 'exit.
* src/keyboard.c (Frecursive_edit): Document throwing a function
to 'exit (bug#49700).
* lisp/minibuffer.el (minibuffer-quit-recursive-edit): New optional
argument to specify how many levels of recursion to quit.
* src/eval.c (internal_catch): Remove special handling of 'exit
tag (bug#49700).
* src/minibuf.c (Fabort_minibuffers): Use
minibuffer-quit-recursive-edit to quit multiple levels of minibuffer
recursion.
* src/xdisp.c (handle_fontified_prop): Set the frame's
inhibit_clear_image_cache flag around calls to
'fontification-functions', to avoid Lisp triggering the clearing
of image and/or face caches behind redisplay's back. (Big#50571)
The reader has an extra 1-char unread buffer that was incorrectly
initialised to 0, which means that the first character read would
always be NUL. As this is often the code that looks for the
lexical-binding cookie, the first loaded source module would be
treated as dynamically bound. During bootstrapping this is loadup.el
and so its local variables got dumped into the global environment.
* src/lread.c (unread_char): Initialise to empty.
(Fload): Initialise here too just in case.
* src/keymap.c (syms_of_keymap)
<describe-bindings-check-shadowing-in-ranges>: New variable.
(describe_vector): Check shadowing of consecutive keys only if
'describe-bindings-check-shadowing-in-ranges' is non-nil. Remove
redundant second loop when VECTOR is a char-table. Improve
comments. Patch by Stefan Kangas <stefan@marxist.se>. (Bug#45379)
* test/src/keymap-tests.el
(help--describe-vector/bug-9293-one-shadowed-in-range): Adapt the
test case for the new variable.
* src/fileio.c (expand-file-name): Check for null bytes for both
NAME and DEFAULT-DIRECTORY arguments. Also check for null bytes
in buffer-local default-directory, assuming it is used.
* src/coding.c (encode_file_name): Use CHECK_STRING_NULL_BYTES.
* src/lisp.h (CHECK_STRING_NULL_BYTES): Add function for checking
for null bytes in Lisp strings.
* test/src/fileio-tests.el (fileio-test--expand-file-name-null-bytes):
Add test for new changes to expand-file-name.
* etc/NEWS: Announce changes.
* src/xterm.c (x_draw_stretch_glyph_string):
* src/w32term.c (w32_draw_stretch_glyph_string): Fix drawing
stretch glyphs when the window is hscrolled. (The original
pre-Jan-2021 code was almost correct, except that it used
'window_box_left_offset' instead of 'window_box_left', and didn't
restrict the background_width fixup to text-area.) (Bug#50564)
* doc/lispref/minibuf.texi (Yes-or-No Queries):
* doc/lispref/os.texi (Suspending Emacs):
* doc/lispref/tips.texi (Programming Tips):
* doc/misc/gnus-faq.texi (FAQ 5-9):
* lisp/subr.el (y-or-n-p):
* src/fns.c (Fyes_or_no_p): Doc fix to reflect that a trailing space
is no longer needed; one is added or removed automatically.
* src/xfaces.c (clear_face_cache): Don't clear fonts and faces of
a frame that is being redisplayed, just because it's time for some
routine maintenance. (Bug#50571)
* src/xdisp.c (redisplay_internal):
* src/frame.h (struct frame) <inhibit_clear_image_cache>: Update
commentary of using this struct member.
* src/comp.c (DEF_DLL_FN, init_gccjit_functions): Don't load and
don't define functions/macros if libgccjit doesn't have them, to
avoid compiler warnings.
* src/nsmenu.m (update_frame_tool_bar): Ensure both sides of the test
are booleans.
* src/nsterm.m ([EmacsWindow createToolbar:]): Make the toolbar
non-visible initially, in case things get out of sync. Remove call to
update_frame_tool_bar: the window isn't yet associated with the view,
so it will return immediately.
* lisp/tab-bar.el (tab-bar--key-to-number): Return non-nil non-numeric t
when no tab is used. Return nil for current-tab.
(tab-bar-mouse-select-tab, tab-bar-mouse-close-tab): Do nothing
when tab-bar--key-to-number returns non-nil non-numeric t
for click events outside of any tab.
(tab-bar-mouse-context-menu): Add context menu when mouse is clicked
outside of tabs. Add "Duplicate" alongside with "Close" to the menu
used when mouse is clicked on a tab.
(toggle-tab-bar-mode-from-frame, toggle-frame-tab-bar): Move code
closer to 'tab-bar-show'.
* src/xdisp.c (handle_tab_bar_click): Return Qtab_bar with empty list
when mouse is clicked on the tab bar but outside of any tab.
* src/xterm.c (x_draw_image_relief):
* src/w32term.c (w32_draw_image_relief): Fix the display of
tab-bar buttons when mouse pointer moves off the button.
(Bug#50424)
* src/keyboard.c (make_lispy_position): Call
'window_from_coordinates' with last 2 arguments non-zero, to have
it report on tool-bar and tab-bar positions. Tweak the return
value according to the expectations of 'make_lispy_event'.
(make_lispy_event): No more need to inject "tab-bar" into a click
event on the tab bar: it's already there.
* src/pdumper.c (dump_map_file_w32): Use PAGE_WRITECOPY flag when
calling CreateFileMapping for DUMP_MEMORY_ACCESS_READWRITE access,
as that is required by Windows 9X. (Bug#50453)
* lisp/emacs-lisp/comp.el ('native-comp-compiler-options): New option.
* lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Add support
for new 'native-comp-compiler-options'.
* src/comp.c (Fcomp_native_compiler_options_effective_p): New function.
(add_compiler_options): New function.
(Fcomp__compile_ctxt_to_file): Call 'add_compiler_options'.
* lisp/tab-bar.el (tab-bar--key-to-number): Rename from tab--key-to-number.
(tab-bar--event-to-item): New function from tab-bar-handle-mouse.
(tab-bar-mouse-select-tab, tab-bar-mouse-close-tab)

Use tab-bar--event-to-item.

(tty_handle_tab_bar_click): Return a list with caption that has
text properties.
* doc/emacs/display.texi (Line Truncation, Visual Line Mode):
* doc/lispref/display.texi (Truncation): Document that turning on
line truncation disables wrapping, and vice versa.
* src/buffer.c (syms_of_buffer) <truncate-lines>:
* src/xdisp.c (syms_of_xdisp) <truncate-partial-width-windows>:
Warn against turning on when 'visual-line-mode' is in effect.
* lisp/simple.el (visual-line-mode): Document that this mode
disables line truncation. (Bug#29664)
* src/frame.c (Fmake_terminal_frame): Make a separate copy of the
faces for the new frame before calling modify-frame-parameters, as
on TTY frames that needs the faces already set up. (Bug#34715)
* src/keyboard.c (access_keymap_keyremap): Don't assume an invalid
function is specified as a symbol. Reported by Perry E. Metzger
<perry@piermont.com>.
* lisp/emacs-lisp/timer.el (timer): Add new slot integral-multiple.
(timerp): Adjust.
(timer-event-handler): Recompute the delay if requested
(bug#39099).

parameter.
