* lisp/image-dired.el (image-dired-queue-active-limit): Increase the
number of asynchronous thumbnail generation jobs to a maximum of 4 or
processor count divided by 2. This makes thumbnail generation around
30 % faster when benchmarking this on my machine (8 cores/4 jobs).
(image-dired-debug): New defvar.
(image-dired-debug-message): New defun.
(image-dired--generate-thumbs-start): New defvar.
(image-dired-create-thumb-1, image-dired-display-thumbs): Display time
spent on thumbnail generation if 'image-dired-debug' is non-nil.
* lisp/xdg.el (xdg-config-home, xdg-cache-home, xdg-data-home)
(xdg-runtime-dir, xdg-config-dirs, xdg-data-dirs): Copy in the
text from the XDG Base Directory Specification to better explain
what these functions return.
* lisp/progmodes/cc-engine.el (c-laomib-loop): Check for a virtual semicolon
as well as a ;.
(c-guess-basic-syntax): CASE 5D - Use c-crosses-statement-barrier-p to check
whether we've gone back past a virtual semicolon.
It is the natural name after the addition of `xref-go-forward`.
The old name is retained as an alias.
* lisp/progmodes/xref.el (xref-pop-marker-stack): Rename.
(xref-go-forward, xref-quit-and-pop-marker-stack)
(xref-find-definitions):
* lisp/menu-bar.el (menu-bar-goto-menu):
* lisp/progmodes/etags.el (find-tag-marker-ring, pop-tag-mark):
* lisp/progmodes/prog-mode.el (prog-context-menu):
* doc/emacs/maintaining.texi (Looking Up Identifiers):
* etc/NEWS:
Use the new name.
Background: Exchange servers cannot accept "charset utf-8" search
strings. The code originally set that charset for any server with
literal+ capability, borking all searches on an Exchange server. This
code only sets utf-8 for multibyte search strings in particular, which
would be borken for Exchange anyway.
* lisp/gnus/gnus-search.el (gnus-search-imap-search-command): Ensure
we're only doing the literal+ dance for multibyte strings (multibyte
strings will have had newlines inserted in an earlier step).
This reverts commit 98eb6d783a.
I've consulted with Richard Stallman about this, and he says
that the original wording, "kinds of atom", is both correct
and more elegant writing. So I'm restoring the original text.
* doc/lispintro/emacs-lisp-intro.texi (Lisp Atoms): Undo the
fix of a "typo" that wasn't a typo. (Bug#51271)
Make it possible to go forward as well as back in the Xref history.
The new `xref-go-forward` is bound to `C-M-,`.
* lisp/progmodes/etags.el (find-tag-marker-ring-length): Update.
(tags-location-ring-length): New.
(find-tag-marker-ring): Keep as dummy.
(tags-location-ring, tags-reset-tags-tables):
Use `tags-location-ring-length` instead of `xref-marker-ring-length`.
* lisp/progmodes/xref.el (xref-marker-ring-length, xref-marker-ring)
(xref-set-marker-ring-length):
Make obsolete.
(xref--history, xref-go-forward, xref-forward-history-empty-p): New.
(xref-push-marker-stack, xref-pop-marker-stack)
(xref-clear-marker-stack, xref-marker-stack-empty-p):
Use `xref--history`.
* lisp/menu-bar.el (menu-bar-goto-menu): Add Forward entry.
* doc/emacs/maintaining.texi (Looking Up Identifiers): Document.
* etc/NEWS: Announce.
* doc/lispref/display.texi (Progress): Document it.
* lisp/subr.el (with-delayed-message): Change the syntax to allow
future extensibility.
* lisp/net/eww.el (eww-display-html): Use it.
* doc/lispref/windows.texi (Buffer Display Action Alists):
Describe new possible values for 'window-height', 'window-width'
and 'window-size' action alist entries.
* lisp/window.el (window--display-buffer): Handle new values for
'window-height', 'window-width' and 'window-size' ALIST entries.
(display-buffer): Update doc-string for new values of some
action alist entries.
* etc/NEWS: Mention new values of some action alist entries.
* lisp/xdg.el (xdg-state-home): New function. This returns
$XDG_STATE_HOME according to the XDG Base Directory Specification
version 0.8 (08th May 2021).
* lisp/image-dired.el (image-dired-show-all-from-dir-max-files):
Double the amount of files in directory before prompting. This could
be even higher, as the thumbnails are generated asynchronously and are
small by default.
* lisp/image-dired.el (image-dired-cmd-create-thumbnail-program)
(image-dired-cmd-create-thumbnail-options)
(image-dired-cmd-create-temp-image-program)
(image-dired-cmd-create-temp-image-options)
(image-dired-cmd-rotate-thumbnail-program)
(image-dired-cmd-rotate-thumbnail-options): Add support for the
GraphicsMagick command line tool ("gm convert", "gm mogrify").
* lisp/image-dired.el
(image-dired--thumbnail-managing-standard-sizes): New defconst.
(image-dired-thumbnail-storage)
(image-dired-thumb-name, image-dired-insert-thumbnail)
(image-dired-thumb-size, image-dired-create-thumb-1): Support larger
thumbnail sizes mandated by new version of the Thumbnail Managing
Standard (December 2020, Version 0.9.0).
* lisp/image-dired.el (image-dired-dir): Doc fix; clarify that
thumbnails will be saved in "$XDG_CACHE_HOME/thumbnails", as per the
Thumbnail Managing Standard.
(image-dired-thumb-size): Doc fix; clarify that this option will be
ignored when using the Thumbnail Managing Standard.
* lisp/image-dired.el (image-dired-thumb-name): Improve docstring.
Use SHA1 for hashing when creating file name. SHA1 is slightly faster
than MD5, and has a few more bits.
* doc/lispref/display.texi (Progress): Document it.
* lisp/subr.el (with-delayed-message): New macro.
* src/eval.c (with_delayed_message_display)
(with_delayed_message_cancel): Helper functions.
(Ffuncall_with_delayed_message): New function (bug#19776).
This aims to fix the scenario where on jit-lock's first scan of a type, it is
not recognized as such, and only later does this happen. The fontification of
such found types is now done by background scanning in short time slices
immediately after initialising the mode.
* lisp/progmodes/cc-engine.el (c-add-type-1): New function.
(c-add-type): Extract c-add-type-1 from it, and reformulate the mechanism for
protecting c-found-types from excessive partial identifiers.
* lisp/progmodes/cc-fonts.el (c-font-lock-complex-decl-prepare): Remove the
code which cleared c-found-types on fontification at BOB.
(c-find-types-background): New function, based on c-font-lock-declarations).
(c-type-finder-timer-func): New function.
(c-re-redisplay-timer): New variable.
(c-force-redisplay, c-fontify-new-found-type): New functions.
* lisp/progmodes/cc-mode.el (c-type-finder-timer, c-inhibit-type-finder): New
variables.
(c-leave-cc-mode-mode): Nullify c-post-command-hook, c-post-gc-hook, and
c-type-finder-timer when the last CC Mode buffer of a session is killed.
(c-type-finder-pos): New variable.
(c-basic-common-init): Initialize/Install c-post-command, c-c-type-finder-pos,
c-type-finder-timer, and c-post-gc-hook.
(c-new-id-start, c-new-id-end, c-new-id-is-type): New variables.
(c-update-new-id): New function.
(c-post-command): New post command hook function, used for checking moving
away from partially typed identifiers, and making them full identifiers.
(c-post-gc-hook): New hook to prevent CC Mode activity immediately following
GC, thus allowing keyboard/mouse input to be registered.
(c-before-change): Add code to clear c-found-types on a buffer change at BOB.
(c-after-change): Call c-update-new-id to keep track of partially typed
identifiers.
* doc/misc/cc-mode.texi (Found Types): New @section in the @Chapter Font
Locking.

(c-type-finder-repeat-time, c-type-finder-chunk-size): New customizable
options.
* lisp/image-dired.el (image-dired-dir)
(image-dired-sane-db-file): Create thumbnail directory and
.image-dired_db with umask 077. This avoids creating world readable
copies of private data, and is in fact mandated by the Thumbnail
Managing Standard that we aim to support.
