This was a regression from Emacs 28.
* src/lread.c (skip_lazy_string, read0): Make #@00 read as nil, which
is a quirk from the old reader that we preserve for compatibility.
* test/src/lread-tests.el (lread-skip-to-eof): Verify it.
Reported by Richard Newton.
* lisp/subr.el (use-dialog-box-p): Use dialog boxes also when
invoked from some window-system gesture. (Bug#63655)
(y-or-n-p): Fix the description in the doc string of conditions
under which a dialog box will be used.
* src/fns.c (Fyes_or_no_p): Use the same condition for dialog
boxes as in 'use-dialog-box-p'. Fix the description in the doc
string of conditions under which a dialog box will be used.
* doc/lispref/minibuf.texi (Multiple Queries, Yes-or-No Queries):
Fix the description of conditions under which a dialog box will be
used.
* src/sqlite.c (HAVE_LOAD_EXTENSION): Define to 1 only if
enabling/disabling extension loading is supported as well.
(load_dll_functions, Fsqlite_load_extension): Condition on
HAVE_LOAD_EXTENSION, not on HAVE_SQLITE3_LOAD_EXTENSION.
(Bug#63653)
* src/sqlite.c (sqlite3_db_config) [WINDOWSNT]: Load from the DLL.
(Fsqlite_load_extension): Use 'sqlite3_db_config' to enable and
disable loading of extensions. Add a few free extensions to the
allow-list. Fix testing for the ".dll" extension. (Bug#63590)
* test/src/sqlite-tests.el (sqlite-load-extension): Fix the test
to require successful load if the extension does exist.
* src/editfns.c:
(labeled_restrictions_get_bound): Return a Lisp_Object instead of
a pointer to a struct Lisp_Marker.
(unwind_reset_outermost_restriction, reset_outermost_restrictions)
(Fwiden, Fnarrow_to_region): Adapt to the new return type.
Running arbitrary ELisp code from an atimer is still dangerous,
at least because the regexp engine is not-reentrant, so let's patch up
the case we bumped into. There are probably many other such holes :-(
* src/alloc.c (garbage_collection_inhibited): Make it non-static.
* src/xdisp.c (garbage_collection_inhibited): Declare it.
(set_message, clear_message): Use it as a proxy for "we're in
a dangerous context like within `probably_quit`".
* src/nsterm.m ([EmacsView initFrameFromEmacs:]): Have a second go at
creating the toolbar.
([EmacsWindow createToolbar:]): If there is already a toolbar or the
EmacsView's layer is not an EmacsLayer, then do nothing.
(cherry picked from commit 3adc1e7f37)
* src/xdisp.c (try_window, try_window_id): Account for tab-line,
if present, when converting scroll-margin at the top of the window
to vertical pixel coordinate. (Bug#63201)
* src/dispnew.c (update_window): Make sure a mode-line's row of
the current glyph matrix is disabled when the mode line is not
being displayed. (Bug#63186)
* doc/lispref/text.texi (Parsing HTML/XML):
* src/xml.c (Flibxml_parse_html_region, Flibxml_parse_xml_region):
Update the documentation regarding the use of BASE-URL argument.
(Bug#63125)
* src/image.c (image_create_bitmap_from_data)
(image_create_bitmap_from_file): Specify a Window or a Pixmap
describing the screen, not a back buffer drawable which may not exist.
Otherwise, Emacs crashes on startup when a bitmap icon is in use.
By discussion on emacs-devel, titled "Versioned Tree-sitter parser
libraries".
* src/treesit.c (Vtreesit_str_dot_0): New variable.
(treesit_load_language_push_for_each_suffix): Additionally look for
lib_base_name.0 and lib_base_name.0.0.
(syms_of_treesit): Initialize Vtreesit_str_dot_0.
* src/fns.c (Fline_number_at_pos): Don't signal an error when
ABSOLUTE is nil and POSITION is outside of the narrowing, like the
original Lisp implementation did. Minor speedup by using the byte
position where it is available from the get-go. (Bug#62857)
This was supposed to be a cherry-pick from master, but
isn't, due to the unnecessary rush to fix master without
cleaning up the mess first and without separating changes
that can and cannot be backported.
* src/treesit.c (treesit_traverse_cleanup_cursor): Fix indentation
style.
(Ftreesit_search_subtree, Ftreesit_search_forward)
(Ftreesit_induce_sparse_tree): Fix specpdl unwinding. (Bug#62823)
Do not merge to master.
Earlier we switched to using cursors rather than nodes to traverse the
parse tree. Because cursors need cleanup, we have to catch signals
thrown by the predicate functions and free the cursor. Failing to do
this will result in leaking the cursor whenever the predicate function
signals in a search function. This change fixes the leak.
* src/treesit.c (treesit_traverse_cleanup_cursor): New function.
(Ftreesit_search_subtree)
(Ftreesit_search_forward)
(Ftreesit_induce_sparse_tree): Catch signals. (Bug#62823)
(cherry picked from commit a5eb9f6ad4)
* src/macfont.m (CG_SET_FILL_COLOR_WITH_FRAME_CURSOR): New macro.
(CG_SET_FILL_COLOR_WITH_FRAME_BACKGROUND): New macro.
(macfont_draw): When the cursor's color matches the face background,
set the fill color of the cursor to the face foreground.
* src/nsterm.m (ns_maybe_dumpglyphs_background): When dumping the
background of a glyph string, apply the logic mentioned
above. (Bug#62573)
* src/xdisp.c (get_nearby_bol_pos): Initialize 'bol' to BEGV - 1
instead of 0 (which fixes cursor motion commands in the presence
of a narrowing), adapt the return condition accordingly, and do
not restart the loop when BEGV has been reached.
(get_small_narrowing_begv): Use correct type.
* src/xdisp.c (get_narrowed_width): Use WINDOW_RIGHT_FRINGE_WIDTH,
which works both for character-only terminals and for GUI frames
without fringes.
(get_nearby_bol_pos): Instead of searching for BOL in
[pos-500000..pos], gradually extend the region, starting with
[pos-500..pos]. This is much faster in buffers with some long
lines in the middle of lots of short lines.
This fixes the case when both 'scroll-conservatively' and
'scroll-step' are customized to non-default values.
* src/xdisp.c (try_scrolling): Fix precedence between
'scroll-step' and 'scroll-conservatively' when scrolling with
'previous-line'. (Bug#62530)
Copyright-paperwork-exempt: yes
* test/src/comp-tests.el (61917-1): New test.
* src/comp.c (syms_of_comp): New variable.
* lisp/loadup.el: Store primitive arities before dumping.
* lisp/emacs-lisp/comp.el (comp--func-arity): New function.
(comp-emit-set-call-subr): Make use of `comp--func-arity'.
* src/xdisp.c (get_medium_narrowing_begv):
(get_medium_narrowing_zv): Make these two functions static, they
are only used in xdisp.c.
* src/dispextern.h: Remove the prototypes.
* src/xdisp.c (get_nearby_bol_pos): New function.
(get_small_narrowing_begv): Use it. This makes cursor motion
commands much more accurate in the first 500K characters of each
long line.
This commit does not change any code, it merely renames functions
and clarifies the documentation, to make the code hopefully easier
to grasp.
* src/dispextern.h (struct it): Rename the 'narrowed_begv',
'narrowed_zv', 'locked_narrowing_begv', 'locked_narrowing_zv' to
'medium_narrowing_begv', 'medium_narrowing_zv',
'large_narrowing_begv', 'large_narrowing_zv'. Clarify the
comments.
Update the prototypes of the functions renamed in xdisp.c.
* src/lisp.h: Update the prototypes of the functions renamed in
editfns.c. Remove the prototype of
'safe_run_hooks_maybe_narrowed', which is used only in keyboard.c.
* src/xdisp.c
(get_small_narrowing_begv): Renamed from
'get_closer_narrowed_begv'.

Also add a large comment to explain how Emacs deals with long lines.
* src/keyboard.c:
(safe_run_hooks_maybe_narrowed): Use the new function names from
xdisp.c and editfns.c. Make the function static, and add a
prototype.
* src/editfns.c:
(labeled_restrictions): Renamed from 'narrowing_locks'.
(labeled_restrictions_add): Renamed from 'narrowing_locks_add'.

function name.

name.

(find_automatic_composition): Use the new function name.
* doc/lispref/positions.texi (Narrowing): Add index entry.
This documentation had been previously removed in 1999 in [1]
but was subsequently restored again in a different form in 2006
in [2] as the construct was still supported on some systems.
However it looks like it hasn't done what that documentation
indicated since [3] in 2011, and the final remnant of this
functionality was removed in [4] in 2013; so it seems clear that
it's no longer supported and shouldn't be documented now.

* src/timefns.c (emacs_localtime_rz) [WINDOWSNT]: Unconditionally
call tzset to make sure we pick up all the changes of time zone,
working around the MS CRT caching.
* src/treesit.c (treesit_ensure_parsed): Check for need_reparse after
treesit_sync_visible_region runs, because as the comment says,
treesit_sync_visible_region might modify need_reparse.
