On the NS port, -[EmacsWindow setParentChildRelationships] reattaches
every child frame to its parent via -addChildWindow:ordered:, which also
orders the child window onto the screen. This runs whenever the
parent/child relationships are rebuilt, e.g., when entering non-native
fullscreen, which allocates a fresh EmacsWindow whose initializer
rebuilds the relationships. A child frame that Emacs had made invisible
(e.g. a corfu/company completion popup) was thereby brought back as a
stale, non-responsive child frame. Emacs never repaints to clear it
because frame_redisplay_p trusts FRAME_VISIBLE_P on the NS port and
avoids dealing with the child frame when it is marked as invisible.
Native fullscreen does not trigger this: -toggleFullScreen: hands off to
AppKit without allocating a new window, so the rebuild never runs.
A hidden child frame is normally detached from its parent already: Emacs
hides it with -orderOut: (ns_make_frame_invisible), which per Apple's
documentation removes a child window from its parent before ordering it
out. The fix is therefore not to re-attach a child while it is
invisible; ns_make_frame_visible already reinstates the parent/child link
when the frame is shown again.
* src/nsterm.m ([EmacsWindow setParentChildRelationships]): Only
re-attach a child window when the frame is marked visible.
(ns_make_frame_visible): Explain, with a reference to Apple's
documentation, why the parent/child link must be reinstated on show.
Remove hard-coded state range, now a monotonically increasing
integer.
* lisp/subr.el (progress-reporter-update-functions): Update
docstring.
(progress-reporter-echo-area): Use
'progress-reporter--pulse-characters' length.
(progress-reporter-do-update): Increase 'state' by 1 each pass.
*
lisp/system-taskbar.el (system-taskbar--progress-reporter-update):
Make steps independent of 'progress-reporter-echo-area' steps.
* make-dist (info_files): Include "*.png" images, which are used
in the doc/lispintro/ directory, and should be in the tarball.
This makes sure eintr.info will not need to be rebuilt on the
end-users' systems when a release tarball is being built, due to
the fact that PNG files are copied from doc/lispintro/ and are
thus newer than eintr.info that came with the tarball. We don't
want to force rebuilding Info files when a release tarball is
built because users are not required to have Texinfo installed.
* src/process.c (glib_installs_sigchld_handler): New variable.
(init_process_emacs): Set it when GLib overrides Emacs's SIGCHLD
handler.
* src/process.h (glib_installs_sigchld_handler): Declare.
* src/xwidget.c (Fmake_xwidget): Skip the "about:blank"
workaround when glib_installs_sigchld_handler is false.
This fixes bug#81084.
* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1):
In the test for a cast near the end of the function, add a test
for a {...} block which isn't a statement block, allowing such
blocks to be recognized as operands of casts.
* lisp/textmodes/markdown-ts-mode.el
(markdown-ts--fontify-unordered-list-marker): Skip leading
whitespace in the node range before applying the display bullet,
since the tree-sitter grammar bundles indent into the first
list_marker_* node.
* src/gtkutil.c (xg_frame_set_char_size)
(xg_frame_set_size_and_position): Round WIDTH and HEIGHT to
multiples of SCALE without adding toolbar/menubar (bug#80662).
* lisp/vc/vc.el (vc--subject-to-file-name): Make the prefix
regex less greedy, ensure the result has no text properties,
improve the docstring (bug#81017).
* lisp/erc/erc-goodies.el (keep-place-indicator): Add
`erc-keep-place-indicator-arrow' face to overlay arrow.
* lisp/erc/erc-stamp.el (erc-stamp--display-prompt-in-left-margin)
(erc--conceal-prompt): Add `erc-prompt-face' to entire `left-margin'
string. See also 9ba65aa9 "Fix missing margin face on display prop in
erc-stamp".
* test/lisp/erc/erc-fill-tests.el (erc-fill--left-hand-stamps): Update
expected text properties on prompt. (Bug#80693)
Now that markdown-ts-view-mode is demoted to "experimental" in emacs-31,
simplify bits of eglot.el and rewrite docs to be more neutral. In
practice 'gfm-view-mode' is still used if found, just like before, but
intrepid users can still try the "experimental" modes.
* lisp/progmodes/eglot.el (eglot-documentation-renderer): Rewrite
doc string.
(eglot--accepted-formats): Rewrite.
(eglot--builtin-mdown-p): Remove.
* doc/misc/eglot.texi (Customization Variables): Rewrite entry.
* etc/EGLOT-NEWS: Tweak.
The old boolean 'eglot-prefer-plaintext' is replaced by the more
expressive 'eglot-documentation-renderer', which can hold a major-mode
symbol, t (plain text), or nil (auto-detect each time). By selecting a
renderer once at startup the repeated per-request lookups are avoided,
which helps with the slowness reported in bug#81150.
* lisp/progmodes/eglot.el (eglot-prefer-plaintext): Declare obsolete
alias to 'eglot-documentation-renderer'.
(eglot-documentation-renderer): New defcustom, reworked from from
eglot-prefer-plaintext.
(eglot--accepted-formats): Use new variable.
(eglot--format-markup): Use new variable.
* etc/EGLOT-NEWS: Announce change.
* doc/misc/eglot.texi (Customization Variables): Document
eglot-documentation-renderer.
* lisp/net/eww.el (eww-form-submit): Call put-text-property to
add help-echo and shr-tab-stop properties.
(eww-tag-input): Exclude inputs with type="submit" when adding
the help-echo and shr-tab-stop properties, since that's now done
in eww-form-submit, called earlier for type="submit".
