This happened with minibuffer-follows-selected-frame set to t.
* doc/emacs/mini.texi (Basic Minibuffer): State where a command's action takes
place when a minibuffer's frame has been deleted.
* lisp/window.el (window--before-delete-windows, record-window-buffer): Take
into account that minibuffers are now recorded on w->prev_buffers field.
* src/fns.c (merge_c): New version of `merge' taking a C function, rather than
a Lisp function as the comparison function.
* src/frame.c (do_switch_frame): Pass arguments sf and for_deletion to
move_minibuffers_onnto_frame.
* src/lisp.h (top level): Declare merge_c and
move_minibuffers_onto_selected_frame.
* src/minibuf.c (MB_frame): New Lisp_Object recording the minibuffer's frame.
(choose_minibuf_frame): Remove all code except that which sets minibuf_window
to the current frame's minibuffer.
(minibuffer_ent_greater): New comparison function, passed to merge_c.
(zip_minibuffer_stacks): New function.
(move_minibuffers_onto_frame): Renamed from `move_minibuffer_onto_frame' given
two arguments, the old frame and for_deletion, and simplified. Minibuffers
are now stacked in the mini-window's ->prev_buffers field.
(read_minibuf): Several detailed amendments.
(exp_MB_frame): New Lisp_Object, the expired minibuffer's frame.
(read_minibuf_unwind): Search for the expired minibuffer's frame, rather than
taking it from (unreliable) variables. Switch temporarily to this frame for
tidying up operations.
(minibuffer_unwind): New function which pops a stacked minibuffer.
(syms_of_minibuf): Call staticpro for the two new Lisp variables.
* src/window.c (Fset_window_configuration): Don't record minibuffers with
record-window-buffer.
* src/xdisp.c (gui_consider_frame_title): Remove redundant Fselect_window,
which caused an unwanted frame switch. Amend the arguments to
format_mode_line_unwind_data to match.
* etc/NEWS: Mention changes to 'while-no-input-ignore-events'.
* src/keyboard.c (kbd_buffer_store_buffered_event): Handle also
Qfile_notify and Qdbus_event as ignore_event. (Bug#47205)
* doc/lispref/text.texi (Buffer Contents): Mention text properties
in the `buffer-string' documentation.
* src/editfns.c (Fbuffer_string): Mention text properties in the
doc string (bug#47220).
* lisp/frame.el (set-frame-property--interactive): Internal function to
produce the interactive form of `set-frame-width' and
`set-frame-height'. Offer the current size as default. (Bug#9970)
* src/frame.c (Fset_frame_height): Modify to call
`set-frame-property--interactive'.
(Fset_frame_width): Modify to call `set-frame-property--interactive'.
* doc/lispref/frames.texi (Frame Size): Update the manuals.
* etc/NEWS: Advertise the change (bug#9970).
* src/dispnew.c (update_window): Make sure all glyph rows below
the last visible one are marked as invalid, even when the loop
which "updates the rest of the lines" didn't examine the last
visible row. (Bug#47093)
* src/sysdep.c (sigsegv_stack): Increase size to 64 KiB and align
it to max_align_t. This copies from Gnulib’s c-stack.c, and works
around a portability bug in draft glibc 2.34, which no longer
defines SIGSTKSZ when _GNU_SOURCE is defined.
* lisp/faces.el (help-key-binding): New face.
* lisp/help.el
(help-for-help): Rename from 'help-for-help-internal'. Use
'substitute-command-keys' syntax.
(help): Make into alias for 'help-for-help'.
(help-for-help-internal): Make into obsolete alias for
'help-for-help'.
(help--key-description-fontified): New function to add the
'help-key-binding' face.
(help-key-description, substitute-command-keys)
(describe-map-tree, help--describe-command)
(help--describe-translation, describe-map):
* lisp/help-fns.el (help-fns--key-bindings, describe-mode):
Use above new function.
* lisp/isearch.el (isearch-help-for-help-internal): Use
`substitute-command-keys' syntax.
* lisp/help-macro.el (make-help-screen): Use
'substitute-command-keys' and 'help--key-description-fontified'.
Simplify.
* src/keymap.c (describe_key_maybe_fontify): New function to add
the 'help-key-binding' face to keybindings.
(describe_vector): Use above new keybinding.
(syms_of_keymap) <Qfont_lock_face, Qhelp_key_binding>: New
DEFSYMs.
(fontify_key_properties): New static variable.
* lisp/tooltip.el (tooltip-show): Avoid overriding faces in
specified tooltip text.
* test/lisp/help-tests.el (with-substitute-command-keys-test):
Don't test for text properties.
(help-tests-substitute-command-keys/add-key-face)
(help-tests-substitute-command-keys/add-key-face-listing):
New tests.
Further testing seems to confirm my suspicion that the increase in the
specpdl comes from the recent change to `pcase--if`.
* lisp/international/mule-cmds.el (update-leim-list-file): Revert workaround.
* src/marker.c (unchain_marker): Clean up obsolete comment
(bug#46836).
Commit cf3164523b (* src/alloc.c: Avoid O(N²) complexity when
unchaining markers (bug#24548)., 2018-03-23) removed the call from GC
into unchain_marker, so there is no need to warn about it.
* src/gtkutil.c (update_frame_tool_bar): Don't keep around a
'char *' pointer to a Lisp string's contents when calling Lisp,
because that could relocate string data; keep the Lisp string
itself instead. This avoids crashes in Mew. (Bug#46791)
* src/fns.c (Fyes_or_no_p): Don't use braces around one-line
block.
(syms_of_fns) <use-short-answers>: Improve the wording of the doc
string.
* etc/NEWS: Improve wording of the entry about 'use-short-answers'.
* src/nsterm.m ([EmacsView windowDidChangeBackingProperties:]):
([EmacsView viewWillDraw]): Only run this code when actually drawing
to an offscreen bitmap.
In some situations involving Internet access not being fully
functional, gnutls_handshake returns a fatal error, which we were
ignoring, causing us to call gnutls_handshake again. Now we check for
the error and return it to the caller.
* src/gnutls.c (gnutls_try_handshake): Return immediately if
gnutls_handshake returns a fatal error (Bug#46709).
* src/xdisp.c (resize_mini_window): Resize the mini-window
when multi-line text is displayed under truncate-lines
non-nil in the minibuffer. (Bug#46718)
Simplify closure creation by calling a single function at run time
instead of putting it together from small pieces. This is faster
(by about a factor 2), takes less space on disk and in memory, and
makes internal functions somewhat readable in disassembly listings again.
This is done by creating a prototype function at compile-time whose
closure variables are placeholder values V0, V1... which can be seen
in the disassembly. The prototype is then cloned at run time using
the new make-closure function that replaces the placeholders with
the actual closure variables.
* lisp/emacs-lisp/bytecomp.el (byte-compile-make-closure):
Generate call to make-closure from a prototype function.
* src/alloc.c (Fmake_closure): New function.
(syms_of_alloc): Defsubr it.
* src/data.c (syms_of_data): Defsym byte-code-function-p.
* lisp/emacs-lisp/byte-run.el (byte-run--set-modes): Change from
being a predicate to storing the modes. This allows using the
modes for positive command discovery, too.
* src/data.c (Fcommand_modes): Look at the `command-modes' symbol
property, too.

necessary since it can just use a predicate.

extended `interactive' form.

extended `interactive' form.
* src/callint.c (Finteractive): Document the extended form.
* src/data.c (Finteractive_form): Return the interactive form in
the old format (even when there's an extended `interactive') to
avoid having other parts of Emacs be aware of this.
(Fcommand_modes): New defun.
* src/emacs-module.c (GCALIGNED_STRUCT): Allow for modules to
return command modes.
* src/lisp.h: New function module_function_command_modes.

still garbaged.
