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.
The new FOR_EACH_TAIL code detects simple cycles sooner than the old
code did, leading to integer overflows.
* src/fns.c (Fnthcdr): Avoid integer overflow if cycle is detected
early.
* src/lisp.h (struct for_each_tail_internal): Reduce to two words.
(FOR_EACH_TAIL_BASIC): Add compiler hint to indicate that tail is most
likely Qnil after the loop and a non-nil non-cons is unlikely.
(FOR_EACH_TAIL_STEP_CYCLEP): Rewrite.
* 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.
* lisp/vc/vc-bzr.el (vc-bzr-dir-status-files):
* lisp/vc/vc-cvs.el (vc-cvs-dir-status-files):
* lisp/vc/vc-git.el (vc-git-dir-status-goto-stage):
* lisp/vc/vc-hg.el (vc-hg-dir-status-files):
* lisp/vc/vc-svn.el (vc-svn-dir-status-files): Set the
query-on-exit flag for the processes populating VC-Dir buffers
to nil.
* lisp/plstore.el (plstore-find, plstore-get, plstore--encode)
(plstore--decode): Use 'plstore--has-secret-keys' to replace
manual check for existence of secret keys. (Bug#81061)
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.
When a plstore has entries with secret keys, processing the plstore
file would require decryption first. However, unlike other functions
like 'plstore-get', 'plstore-put', etc., 'plstore-delete' does not
check for secret keys and decrypt the file, which would corrupt the
file when deleting any entries with secret keys.
This patch adds checking for secret keys and decrypt the file when
needed before removing the entry with name.
* lisp/plstore.el (plstore--has-secret-keys): New.
* lisp/plstore.el (plstore-delete): Check for secret keys of the entry
and decrypt plstore before performing the deletion. (Bug#81061)
* src/xterm.c (x_suspend_background_fills)
(x_restore_background_fills): New functions.
(x_set_window_size, x_set_window_size_and_position)
(x_make_frame_invisible): Use them (bug#80961).
* 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)
