* src/xfns.c (x_window): Avoid extraneous
XChangeWindowAttributes.
* src/xterm.c (x_display_set_last_user_time): New argument
SET_PROPERTY. Do not change the user time property if it is not
true. All callers changed.
(handle_one_xevent): Avoid setting the user time property on
LeaveNotify and XI_Leave events.
Binding it causes errors when some of the enclosed code ends up
loading a `.el` file, and it is unnecessary since the rest of
the code (in `url-file-asynch-callback`) is already careful to
use `insert-file-contents-literally`.
* src/fns.c (HAVE_FAST_UNALIGNED_ACCESS): New.
(Fstring_lessp): Only use word operations where safe, because string
data from purespace may be unaligned.
* lisp/emacs-lisp/package.el (package-untar-buffer): Fix thinko.
(package-tar-file-info): Handle the case where the first file is in
a subdirectory.
* test/lisp/emacs-lisp/package-tests.el (package-test-bug58367): New test.
* test/lisp/emacs-lisp/package-resources/ustar-withsub-0.1.tar:
* test/lisp/emacs-lisp/package-resources/v7-withsub-0.1.tar: New files.
* lisp/emacs-lisp/vtable.el (vtable-insert-object): Pass in the
correct ellipsis values (bug#58370).
(vtable--insert-line): Don't bug out on missing optional arguments.
* lisp/files.el (file-in-directory-p): Clarify doc string.
* doc/lispref/files.texi (Truenames): Move the documentation of
'file-in-directory-p' from here...
(Contents of Directories): ...to here. Add index entries.
(Bug#58364)
* src/xterm.c (xi_focus_handle_for_device, handle_one_xevent):
Set the last user time where required for focus to be handled
correctly.
(x_focus_frame): Do not perform actions prohibited by the ICCCM.
* lisp/language/misc-lang.el ("Coptic"): New language environment.
Add sample text and input method.
* lisp/international/fontset.el (script-representative-chars)
(setup-default-fontset): Support coptic.
* lisp/leim/quail/misc-lang.el ("coptic"): New input method.
* etc/HELLO: Add a Coptic greeting.
* etc/NEWS: Announce the new language environment.
* lisp/image/wallpaper.el (wallpaper-setter): Add 'init-action'
and 'detach' fields to structure.
(wallpaper--init-action-kill): New helper function.
(wallpaper--default-setters): Use above new fields for "swaybg" and
"wbg", to start/restart the corresponding processes as needed.
(wallpaper-default-set-function): Call 'init-action' function if
there is one. If 'detach', use 'call-process' instead of
'start-process'. (Bug#57781)
* test/lisp/image/wallpaper-tests.el (wallpaper--find-setter)
(wallpaper--find-setter/call-predicate)
(wallpaper--find-setter/set-current-setter)
(wallpaper-set/runs-command, wallpaper-set/runs-command/detach)
(wallpaper-set/calls-init-action)
(wallpaper-set/calls-wallpaper-set-function): New tests.
When Emacs-25 changed the default of `inhibit-point-motion-hooks` to t,
/etc/NEWS declared it as obsolete and so did its docstring, but
it was not marked as obsolete so as not to emit too many warnings
in code where it was impractical to remove the let-binding while
keeping backward compatibility with older Emacsen.
Those backward compatibility issues are not serious any more now that
Emacs-25 is itself considered old.
* lisp/subr.el (inhibit-point-motion-hooks): Mark it as obsolete.
* src/textprop.c (inhibit-point-motion-hooks): Don't mention it being
obsolete in the docstring any more.
* lisp/simple.el (line-move-1, line-move-finish): Silence warnings.
The let-binding was added back in 1997 (commit 79c7a4fa5f)
"because we might have to search inside invisible and intangible text".
So it's been redundant since Emacs-25 changed the default to t.
Keep binding it in Emacs<25 but not in Emacs≥25 (where such bindings
are redundant and the var is declared obsolete).
* lisp/progmodes/verilog-mode.el (verilog-save-buffer-state):
Don't bind `inhibit-point-motion-hooks` if Emacs≥25.
(verilog-save-font-no-change-functions): Same, and refrain from
binding `before/after-change-functions` as well while we're at it,
since `inhibit-modification-hooks` already covers it in Emacs≥25.
Don't use this macro any more since it doesn't do anything since Emacs-25
changed the default of `inhibit-point-motion-hooks` to t.
* lisp/nxml/nxml-util.el (nxml-with-invisible-motion): Delete macro.
* lisp/nxml/nxml-mode.el (nxml-mode, nxml-cleanup):
* lisp/nxml/rng-valid.el (rng-do-some-validation):
* lisp/nxml/rng-nxml.el (rng-set-state-after): Don't use it.
`line-move-1` was written back before `inhibit-point-motion-hooks`
was made obsolete and it's written under the assumption that its
value is nil, whereas since Emacs-25 it's t.
To work around problems linked to a nil value of
`inhibit-point-motion-hooks`, the code temporarily binds that var to
t while it moves around trying to find the final destination and then
later in a few key spots it binds it "back" to nil so as to run the
point-motion hooks according to the final destination, as if the
overall motion had been made "normally".
Change the code so that the "bind back" indeed binds the var back to
the value it had originally, rather than always to nil.
* lisp/simple.el (line-move-1): Obey `inhibit-point-motion-hooks`
(line-move-finish): New optional arg `not-ipmh`.
Remove binding of `inhibit-point-motion-hooks` (it's t by default
anyway and it's obsolete) and don't "manually" bind
`inhibit-modification-hooks`.
* lisp/org/org.el (org-unfontify-region): Use `with-silent-modifications`.
(org-display-inline-remove-overlay): Remove ineffective binding of
`inhibit-modification-hooks` around code which doesn't modify the
buffer anyway.
There were many reinventions of `with-silent-modifications` (tho
many of them weren't reinventions but copy&paste of code from
font-lock, IIUC). Now that those don't even need to let-bind
`inhibit-point-motion-hooks` they're really just obsolete.
* lisp/font-lock.el (save-buffer-state): Delete macro.
(font-lock-unfontify-region, font-lock-default-fontify-region):
Use `with-silent-modifications` instead.
(font-lock-after-change-function, font-lock-fontify-block): Don't
let-bind `inhibit-point-motion-hooks`.
* lisp/htmlfontify.el (hfy-save-buffer-state): Delete macro.
(hfy-mark-trailing-whitespace, hfy-unmark-trailing-whitespace):
Use `with-silent-modifications` instead.
* lisp/jit-lock.el (with-buffer-prepared-for-jit-lock): Delete macro.
(jit-lock--debug-fontify, jit-lock-refontify, jit-lock-function)
(jit-lock-fontify-now, jit-lock-force-redisplay)
(jit-lock-deferred-fontify, jit-lock-context-fontify)
(jit-lock-after-change): Use `with-silent-modifications` instead.
* lisp/progmodes/antlr-mode.el (save-buffer-state-x): Delete macro.
(antlr-hide-actions): Use `with-silent-modifications` instead.
* lisp/progmodes/hideshow.el (hs-life-goes-on): Don't
let-bind `inhibit-point-motion-hooks`.
Improve comparison speed when both arguments are multibyte strings,
at least one of them containing a non-ASCII character. (All-ASCII
multibyte strings are already fast.)
The speed-up is about 2× for strings of 10 chars, 10× for strings of
100 chars.
* src/fns.c (Fstring_lessp): Quickly skip the common prefix by
comparing words.
* lisp/comint.el (comint-output-filter): Propertize process output
with field=output before inserting it into buffer to prevent
comint-fontify-input from fontifying it (bug#58169).
