* lisp/desktop.el (desktop-clear): check that buffer is not already
killed before attempting to kill it. A buffer might become killed as
part of regular operation as a side-effect of killing another buffer,
and then attempt to kill it again causes error (bug#49692).
Copyright-paperwork-exempt: yes
* lisp/cus-start.el (standard): Don't mention the Lisp values in
the choice strings, because that's just confusing in the Customize
interface (bug#49687).
* lisp/emacs-lisp/cl-lib.el: Move all the generalized variable
specifications from cl-lib.el...
* lisp/emacs-lisp/gv.el: ... to gv.el. This will make things like
`(setf (getenv "FOO") "BAR")' work without requiring anything,
since `setf' lives in gv.el (bug#49651).
* lisp/vc/vc-git.el (vc-git-mode-line-string): Make function more
robust (bug#49683). It could previously error out under certain
conditions, like moving directories in and out of the
VC-controlled tree.
Copyright-paperwork-exempt: yes
Use it to obey `byte-compile-warnings`.
(macroexp--warn-wrap): Add arg `category`.
(macroexp-macroexpand, macroexp--expand-all): Use it.
* lisp/emacs-lisp/cconv.el (cconv--convert-funcbody, cconv-convert):
Mark the warnings as `lexical`.
* lisp/emacs-lisp/eieio-core.el (eieio-oref, eieio-oref-default)
(eieio-oset-default):
* lisp/emacs-lisp/eieio.el (defclass): Adjust to new calling convention.
* src/frame.h (struct frame): Add face_hash_table, remove face_alist.
(fset_face_hash_table): New function.
(fset_face_alist): Remove.
* src/frame.c (make_frame): Initialize f->face_hash_table.
(Fmake_terminal_frame): Update to work with hash tables instead of
alists.
* src/xfaces.c (lface_from_face_name_no_resolve):
(Finternal_make_lisp_face):
(update_face_from_frame_parameter): Update to work with hash tables
instead of alists.
(Fframe_face_hash_table): New function.
(Fframe_face_alist): Move to faces.el as frame-face-alist.
(syms_of_xfaces): Add frame_face_hash_table.
* lisp/progmodes/elisp-mode.el (elisp--eval-defun-1):
* lisp/frame.el (frame-set-background-mode): Update to work with hash
tables instead of alists.
* lisp/faces.el (face-new-frame-defaults): Mark obsolete.
(face-list): Update to use face--new-frame-defaults.
(frame-face-alist): Moved here from src/xfaces.c.
(x-create-frame-with-faces): Update to handle subtle semantic change
to how frame faces propagate, which otherwise breaks frame creation
with reverse video enabled (bug#41200).
Reworked from a patch by Clément Pit-Claudel <clement.pitclaudel@live.com>.
* src/chartab.c (char_table_ref_simple): New function...
(sub_char_table_ref_and_range, char_table_ref_and_range):
...factored out from here. (bug#45550).
Found by Pip Cet.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-quote): Fix mistake that
made this optimiser ineffective at removing quoting of nil, t, and
keywords. The only obvious consequence is that we no longer need...
(byte-optimize-form): ...a 'nil => nil normalising step here; remove.
(byte-optimize-form-code-walker): Make the compiler warn about (quote).
* lisp/emacs-lisp/bytecomp.el (byte-compile--cond-switch-prefix):
Treat (not VAR) and (null VAR) as (eq VAR nil) when computing the
extent of switch ops.
* lisp/autorevert.el (auto-revert-mode):
* lisp/files.el (revert-buffer): Mention that there is
revert-buffer-with-fine-grain that is better suited for markers
preservation (bug#49661).
* lisp/emacs-lisp/package.el (package-install-from-buffer): Allow
installing files with different line ending conventions (Unix, DOS
and Macos) (bug#48137).
* src/json.c (Fjson_serialize, Fjson_insert)
(Fjson_parse_string, Fjson_parse_buffer, syms_of_json): Signal
`json-unavailable' if jansson isn't available (bug#48228).
* doc/lispref/commands.texi (Quitting): Document `minibuffer-quit'
(Recursive Editing): Document throwing of function values to `exit'.
* doc/lispref/errors.texi (Standard Errors): Document
`minibuffer-quit'
* lisp/minibuffer.el (minibuffer-quit-recursive-edit): New function.
* lisp/simple.el (minibuffer-error-function): Do not abort keyboard
macro execution if is minibuffer-quit is signaled (bug#48603).
* src/data.c (syms_of_data): New error symbol `minibuffer-quit'
* src/keyboard.c (recursive_edit_1): Implement throwing of function
values to `exit`. In that case, the function will be called without
arguments before returning from the command loop.
(cmd_error):
(Fcommand_error_default_function): Do not abort keyboard macro
execution if minibuffer-quit is signaled.
(command_loop_2): New argument HANDLERS.
* src/macros.c (Fexecute_kbd_macro): Use command_loop_2 instead of
command_loop_1.
* src/minibuf.c (Fabort_minibuffers): Use it.
* doc/emacs/search.texi: Document these additions.
* lisp/replace.el:
Add the commands 'kill-matching-lines' and 'copy-matching-lines'.
'kill-matching-lines' is like 'flush-lines', but adds the lines to the
kill ring as a single string, keeping line endings.
'copy-matching-lines' is like 'kill-matching-lines', but only copies
those lines instead of killing them.
* lisp/dnd.el (dnd-open-local-file): Add file to history.
* lisp/files.el (file-name-history--add): New function (bug#12915).
* lisp/startup.el (command-line-1): Add file to history.
* lisp/wdired.el (wdired--before-change-fn):
(wdired--restore-properties): Widen before doing anything so that
we get all the changed bits (bug#49124).
* lisp/help-fns.el (describe-variable): Store the type.
* lisp/help-mode.el (help-view-source): Use the type. This fixes
the problem when looking for a variable defined in a C file.
