* src/xterm.c (x_frame_highlight, x_frame_unhighlight): Skip
changing the frame alpha when the frame is not eligible for
focus state-specific alpha values; otherwise, the alpha might be
reset by the time a alpha change wrought by a focus change
arrives, impeding handle_one_xevent from subsequently restoring
the initial value. (bug#66398)
* src/process.c (create_process) [F_SETPIPE_SZ]: Set the pipe
capacity only if the required read-process-max is larger than the
default capacity of the pipe. (Bug#66288)
* src/nsterm.m (ns_init_locale): If LANG is set, try to use that,
otherwise try to deduce what LANG should be. Check is the result is
valid, and use LANG="en_US.UTF-8" if not.
* doc/emacs/macos.texi (Mac / GNUstep Customization):
* src/nsfns.m (syms_of_nsfns): Fix documentation of
'ns-use-proxy-icon'; explain what it does and how it's
used. (Bug#66190)
Somehow the new overlay code in Emacs-29 changed slightly
the test to decide when to run the `modification-hooks` of overlays,
with the consequence that these hook functions end up being executed
also when text is deleted right after an empty overlay, which is
contrary to Emacs-28 behavior as well as contrary to the Texinfo doc.
* src/buffer.c (report_overlay_modification): Better reproduce the
Emacs-28 code.
* test/src/buffer-tests.el (overlay-modification-hooks):
Add corresponding test.
* src/treesit.c (treesit_cursor_helper_1)
(treesit_cursor_first_child_for_byte): Use
ts_tree_cursor_goto_first_child_for_byte first, and
ts_tree_cursor_goto_first_child second.
* src/pdumper.c (dump_buffer): Fix hash for 'struct buffer'. The
recent changes to that structure where commits
8f3091defb and
0bd4661941, both of which just affected
comments.
* doc/lispref/sequences.texi (Char-Tables):
* src/chartab.c (Fchar_table_range): Clarify what
'char-table-range' returns for an argument that is a cons cell.
* src/treesit.c: (treesit_cursor_helper_1): Use
ts_tree_cursor_goto_first_child_for_byte to speed up traversing among
siblings. The "while (ts_node_end_byte (cursor_node) < end_pos)" can
be removed with the check added in the loop below.
* src/w32term.c (w32_construct_mouse_wheel): The number of lines
to scroll should always be positive in wheel-scroll events.
Whether to scroll up or down is encoded in the modifiers, which
produce either wheel-up or wheel-down event. (Bug#65070)
* doc/lispref/commands.texi (Misc Events): Clarify the
documentation of 'wheel-up' and 'wheel-down' events.
* doc/emacs/search.texi (Replacement and Lax Matches):
* src/search.c (Freplace_match):
* lisp/replace.el (query-replace, query-replace-regexp): Clarify
in the doc string and the manual how letter-case is transferred
from the replaced text to the replacement text. (Bug#65347)
* src/xdisp.c (get_next_display_element): If we have no usable
face to display a character/composition, treat that as glyphless.
(produce_glyphless_glyph): If neither it->face nor its ASCII face
are usable, fall back to the frame's default font. (Bug#65198)
* src/emacs.c (main): Move the handling of the -x switch out of
the HAVE_X_WINDOWS condition, and simplify the rest of the code by
avoiding code duplication in HAVE_X_WINDOWS and !HAVE_X_WINDOWS
cases. (Bug#65048)
* src/keymap.c (possibly_translate_key_sequence): Don't signal an
error if 'key-valid-p' returns nil. Suggested by Stefan Monnier
<monnier@iro.umontreal.ca>. (Bug#64927)
* src/keyboard.c (Fthis_single_command_keys): Don't allow calls to
Fvector with negative first argument. (Bug#64857)
