* lisp/emacs-lisp/edebug.el (edebug-prepare-margin): New
function to set up left margin for Edebug.
(edebug--display-1): Use it.

* doc/emacs/building.texi (Debugger Operation): Document the
change.
* etc/NEWS: Announce the change.
* src/editfns.c (Freplace_region_contents): If the temporary
storage is so large that malloc fails, do not signal an error.
Instead, fall back on destructive replacement.
This change helps ensure that work buffers are "clean" for reuse
by arbitrary callers.
* lisp/emacs-lisp/subr-x.el (work-buffer--release): Call
'kill-all-local-variables' with KILL-PERMANENT 'reset.
* src/buffer.c (Fkill_all_local_variables): If KILL-PERMANENT is
'permanent-local, kill all locals without prejudice. If
KILL-PERMANENT is 'reset, also call 'reset_buffer'.

This is necessary to correctly read keys like 'M-~'
used by 'save-some-buffers' that is two keys 'ESC ~'
on a tty.
* doc/lispref/minibuf.texi (Multiple Queries):
Index 'y-or-n-p-use-read-key' for 'map-y-or-n-p'.
Mention using a key sequence instead of single keys.
* lisp/emacs-lisp/map-ynp.el (map-y-or-n-p):
In the 'y-or-n-p-use-read-key' cond-branch,
use 'read-key-sequence-vector' instead of 'read-key'.
In the default cond-branch, use 'this-command-keys-vector'
instead of 'last-command-event'. In both cond-branches
use 'key-description' instead of 'single-key-description'
(bug#81168).
Instead of '(eq def nil)' check if chars are either nil
or an empty vector in noninteractive mode (bug#67836).

e33e9f7e85 Document 'margin' face as base for margin display strings...
cff9c8bc00 Improve prompting for mail sending by by 'report-emacs-bug'
# Conflicts:
# etc/NEWS
* etc/NEWS:
* doc/lispref/frames.texi (Font and Color Parameters):
* doc/lispref/display.texi (Displaying Faces, Basic Faces):
Improve indexing of faces and wording of the description of the
'margin' face and its implications.
* doc/lispref/display.texi (Displaying Faces): Note that the
underlying-text rule does not apply to strings displayed in the
display margins, and reword the margin-face bullet to describe
'margin' as the base.
(Basic Faces): Note that the 'margin' face also provides the base
attributes for strings displayed in the margins.
(Display Margins): Drop a sentence that restated the preceding one
about unspecified attributes inheriting from 'margin'.
* etc/NEWS: Document the change for margin strings.
Suggested by F. Jason Park <jp@neverwas.me>.
* lisp/calendar/time-date.el (format-seconds): Document that the arg
can be any time value, and need not be a number.
This has been true for some time, but has not been documented.
Avoid some (but not all) rounding errors internally, and add a
comment about the remaining rounding error.
* lisp/emacs-lisp/timer-list.el (list-timers):
* lisp/org/org-timer.el (org-timer-show-remaining-time):
* lisp/org/ox.el (org-export--stack-generate):
* lisp/time.el (emacs-uptime): Omit unnecessary conversion of time
value that can increase rounding error.
* test/lisp/calendar/time-date-tests.el (test-format-seconds):
Test that format-seconds works on time values that are not numbers.
Since Emacs-27, `package-initialize` is for internal use only,
and callers should either call `package-activate-all` instead
(cheaper and faster) or do nothing at all (because the other
functions should trigger the needed initialization automatically
as needed).
* doc/lispref/package.texi (Packaging Basics): Delete `package-initialize`.
* doc/misc/eglot.texi (Reporting bugs): Don't recommend using `package-initialize`.
* doc/misc/org.org (Using Emacs packaging system): Simplify the command
line since both `(require 'package)` and `(package-initialize)` are
redundant here.
A new basic face 'margin' is used for text displayed in the left and
right margin areas, i.e., the areas typically used by VCS and LSP
packages for per-line annotations. Its background defaults to the
frame default, preserving existing behavior for users who do not
customize it.
* etc/NEWS: Document the new 'margin' face.
* lisp/faces.el (margin): Add 'margin' face, inheriting from 'default'.
* src/dispextern.h (face_id): Add MARGIN_FACE_ID.
* src/xdisp.c (face_at_pos): Use 'margin' as the base face for
strings displayed in margin areas so that they inherit the gutter
background by default.
(extend_face_to_end_of_line): Compute 'margin_fill_face_id' from the
'margin' face. Use while loops to explicitly fill all empty character
slots in both left and right margins for both GUI and TTY branches.
(display_line): Call 'extend_face_to_end_of_line' for beyond-EOB rows
when the window has margins. Also extend the existing condition for
text rows with empty margins to trigger when the 'margin' face
background differs from the frame default, not only when the default
face is remapped.
* src/xfaces.c (realize_basic_faces): Realize 'margin' as a basic
face to support face-remapping and efficient lookup.
(Bug#80693)
'setopt-local' is the buffer local equivalent of 'setopt'.
Unify 'setopt', 'setopt-local', 'setq-local',
'buffer-local-set-state' with 'setq' to signal
'wrong-number-of-arguments'.
* lisp/cus-edit.el (setopt): Change error signal to
'wrong-number-of-arguments'.
(setopt-local): New macro.
(setopt--set-local): New function.
* lisp/subr.el (set-local): New function.
(setq-local, buffer-local-set-state): Signal
'wrong-number-of-arguments' rather than 'error'.
* doc/emacs/custom.texi (Examining): Document 'setopt-local'.
* etc/NEWS: Announce the new macro and function.
This introduces the predicate frame-initial-p, which uses
struct frame.output_method or struct terminal.type to detect
initial_terminal without relying on its name (bug#80629).

* lisp/emacs-lisp/byte-opt.el: Mark frame-initial-p as error-free.
* src/pgtkterm.c (pgtk_focus_changed): Use IS_DAEMON in place of
Fdaemonp, thus also accepting a named daemon session.
* src/terminal.c (decode_tty_terminal): Clarify commentary.
(Fframe_initial_p): New function.
(syms_of_terminal): Expose it.
(init_initial_terminal): Update commentary now that
menu-bar-update-buffers uses frame-initial-p (bug#53740).
* test/lisp/xt-mouse-tests.el (with-xterm-mouse-mode): Simulate the
lack of an initial terminal by overriding frame-initial-p now
that turn-on-xterm-mouse-tracking-on-terminal uses it.
* test/src/terminal-tests.el: New file.
Move shortdoc group definitions from shortdoc.el to a separate file
shortdoc-doc.el. Document shortdoc group format in a future-proof way
and guide package authors on how to use shortdoc groups across past
Emacs versions.

(Fwindow_total_width, Fwindow_body_width): Clarify that window
dimensions are returned in canonical columns and lines.
(Bug#80620)
* doc/lispref/lists.texi:
* lisp/emacs-lisp/let-alist.el (let-alist): Improve docs.
Namely, clarify that 'let-alist' does not "see" symbols
introduced by macro-expansion in its body, and that the
generated code looks up symbols in the alist whether or not
they are actually used in runtime.
See also bug#79706 for some relevant discussion.
* doc/lispref/lists.texi (Building Lists): Document it.
* etc/NEWS: Mention it.
* lisp/emacs-lisp/shortdoc.el (list): Demonstrate it.
* lisp/subr.el (ensure-proper-list): Add it.
Remove `error-data` from the new error API: it is not really
compatible with a more abstract view of error descriptors, and
in practice it seems to be used only in two ways (both of them rare):
- To add some contextual info to an error. We should maybe add
a dedicated support for that, but it's not clear what shape it
should take, ideally (there was a discussion about with Alan
and myself in emacs-devel a few years ago).
- To do some other massaging whose correctness is dubious anyway.
* doc/lispref/control.texi (Handling Errors): Remove `error-data`.
* lisp/epa-file.el (epa-file--find-file-not-found-function): Don't use
`error-data`.
(epa-file--error-add-context): New function, extracted from
`epa-file-insert-file-contents`.
(epa-file-insert-file-contents): Use it instead of `error-data`.
* lisp/subr.el (error-data): Delete function.
Define new functions to manipulate error descriptors and
add support for `signal` to *re*signal a previous error.
* src/eval.c (Fsignal): Make the second arg optional and document
the possibility of passing a whole error descriptor to re-signal it.
(signal_or_quit): Fix a few corner case issues when
DATA is `nil` and ERROR_SYMBOL is an error descriptor.
* lisp/subr.el (error-type-p, error--p, error-type, error-data)
(error-has-type-p, error-slot-value): New function.
* doc/lispref/control.texi (Handling Errors): Prefer "error descriptor"
to "error description". Use the new single-arg call to `signal` to
re-throw an error.
Document `error-type`, `error-data` and `error-slot-value`.
(Error Symbols): Document the new functions `error-type-p` and
`error-has-type-p`.
Walking the window tree is more reliable than using the selected
window. Implement 'get-mru-frame' on top of 'get-mru-frames'
using 'frame-use-time'.
* lisp/frame.el (frame-use-time): Change to walk the window tree
for the specified frame.
(get-mru-frames): New defun.
(get-mru-frame): Change to call 'get-mru-frames'.
* doc/lispref/frames.texi: Update documentation.

* lisp/obsolete/cl.el (member-if): Delete obsolete function
alias.
* doc/lispref/lists.texi (List Elements):
* doc/misc/cl.texi (Lists as Sets):
* etc/NEWS: Document the change.
