* lisp/emacs-lisp/cl-macs.el (cl--optimize)
(cl-struct-sequence-type, cl-struct-slot-offset): Autoload since
they are referred to by code in cl-loaddefs.el.
* lisp/emacs-lisp/package.el (package-directory-list)
(package-quickstart-file): Specify group to avoid warning when
byte-compiling loaddefs.el.
(package-activated-list): Autoload since we're assigning the
variable from a function completely autoloaded.
This variable and related functions have been obsolete since 23.1.
The last things to depend on this (fast-lock.el and lazy-lock.el) were
recently removed.
* src/dispextern.h (struct it): Delete field
'redisplay_end_trigger_charpos'.
* src/window.c (Fwindow_redisplay_end_trigger)
(Fset_window_redisplay_end_trigger): Delete defuns and corresponding
defsubrs for functions obsolete since 23.1.
* src/window.h (wset_redisplay_end_trigger): Delete function.
(GCALIGNED_STRUCT): Delete 'redisplay_end_trigger'.
* src/xdisp.c (run_redisplay_end_trigger_hook): Delete function.
(syms_of_xdisp) <redisplay_end_trigger_functions>: Delete
variable obsolete since 23.1.
(init_iterator, next_element_from_buffer): Don't run or set above
deleted hook variable.
* lisp/subr.el: Delete obsoletion definitions for above deleted
defuns and variable.
* doc/lispref/hooks.texi (Standard Hooks):
* lisp/emacs-lisp/byte-opt.el (side-effect-free-fns):
* lisp/loadhist.el (unload-feature-special-hooks): Don't mention
above deleted variable.
* admin/coccinelle/window.cocci: Adjust for above changes.
* lisp/emacs-lisp/icons.el (icons--create): Choose another
character that's unlikely to appear in non-Emoji fonts. (Comment
left in place since this should be fixed in a less breakable way.)
* lisp/emacs-lisp/icons.el (icons--create): Use 'display-images-p'
to test for image capability.
* doc/lispref/display.texi (Icons): Improve indexing,
cross-references, and wording.
* lisp/emacs-lisp/warnings.el (warning-suppress-action)
(warning-suppress-log-action): Removed.
New icon.
(warnings-suppress): New helper function.
(display-warning): Use it (bug#46025).
* doc/emacs/custom.texi (Specific Customization): Mention it.
* doc/emacs/display.texi (Icons): New node.
* doc/lispref/display.texi (Icons): New node.
* lisp/button.el (buttonize):
(button--properties, buttonize-region): Allow not overriding faces.
* lisp/cus-edit.el (custom-save-all): Save icons.
(custom-icon): New widget.
(custom-icon-value-create, custom-toggle-hide-icon)
(custom--icons-widget-value, custom-icon-set): Helper functions
for the widget.
(customize-icon): Main command.
(custom-icon-state-set, custom-icon-state): Helper functions.
(custom-theme-set-icons): Function to be used by theme writers.
(custom-set-icons): Function to be used in .emacs.
(custom-save-icons): New function.
* lisp/custom.el (custom-push-theme): Add icons.
* lisp/emacs-lisp/icons.el: New file.
* test/lisp/emacs-lisp/icons-tests.el: Add some tests.
'package-archives' URLs are expected to end in '/', but we can
cater for people typoing that by using 'url-expand-file-name'.
* lisp/emacs-lisp/package.el (package--with-response-buffer-1): Use
'url-expand-file-name' instead of 'concat'.
Reported by Basil Contovounesios.
* etc/NEWS: Mention how to suppress the warning.
* lisp/emacs-lisp/byte-run.el (with-suppressed-warnings): Amend doc string.
* lisp/subr.el: Use `macroexp-warn-and-return` to delay the warning
until codegen time (which makes it suppressible) and to prevent
repeated warnings.
* test/lisp/international/ccl-tests.el (shift):
* test/src/data-tests.el (data-tests-ash-lsh):
Suppress warning in tests of `lsh` itself.
* lisp/subr.el (lsh): Note the general preference for `ash`.
* lisp/emacs-lisp/shortdoc.el (number): Remove entry for `lsh`.
It was identical to that for `ash` which is misleading.
Shortdoc is very helpful for finding the right function to use,
and `lsh` is just for compatibility at this point.
Previously, it considered only windows on 'visible' frames (according
to get-buffer-window). This seemed correct at first, but it's not
much use for multiple TTY frames and not particularly reliable on GUI
frames either. There's no reliable way to tell what is actually
visible, so it's best to assume that users setup frames that are
indeed visible when using this parameter.
* lisp/emacs-lisp/eldoc.el (eldoc--echo-area-prefer-doc-buffer-p):
Consider all frames.
* lisp/emacs-lisp/seq.el (seq-subseq):
Make faster by using `take` instead of a lisp loop,
and more importantly by not front-loading the error text formatting.
* test/lisp/emacs-lisp/seq-tests.el (seq-tests--list-subseq-ref)
(test-seq-subseq): Test `seq-subseq` for lists more thoroughly.
This optimisation is already done in the code generator but performing
it at this earlier stage is a useful normalising step that uncovers
more opportunities.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-list): New.
* lisp/emacs-lisp/comp.el (comp-final): Mark async worker tmp file
as utf-8.
* test/src/comp-tests.el (48029-1): New test.
* test/src/comp-resources/comp-test-funcs.el
(comp-test-48029-nonascii-žžž-f): New function.
