* doc/emacs/files.texi (Reverting): Document the new command and the
new variable.
* etc/NEWS: Mention the new command and the new variable.
* lisp/files.el (revert-buffer-with-fine-grain): New command. Revert
a buffer trying to be non-destructive, by using replace-buffer-contents.
(revert-buffer-insert-file-contents-delicately): New function, alternative
to revert-buffer-insert-file-contents-function--default-function.
(revert-buffer-with-fine-grain-max-seconds): New variable. Passed as
argument MAX-SECS of replace-buffer-contents.
* test/lisp/files-tests.el (files-tests-lao files-tests-tzu): Helper
variables, taken from diffutils manual, to test reverting a buffer.
(files-tests-revert-buffer)
(files-tests-revert-buffer-with-fine-grain): New tests (bug#18).
* lisp/files.el (magic-fallback-mode-alist): Match "DOCTYPE" in a
case-insensitive way before putting files in mhtml-mode. See
https://html.spec.whatwg.org/multipage/syntax.html#the-doctype for the
standard reference.
* test/lisp/files-tests.el (files-test-magic-mode-alist-doctype): Add
a test (bug#43511).
* lisp/files.el (directory-free-space-program): Doc fix; there is no
need to repeat that its obsolete here since it will be shown by
customize, describe-variable, etc. automatically.
This reverts commit de4f347901.
read-file-name already displays a long path when given a default
(like INITIAL in many other prompting functions), so using
format-prompt here is superfluous.
* lisp/files.el (save-some-buffers): Relax the "similarity" regexp
from the previous regexp: Don't show both file and buffer names if
the file is /tmp/foo and the buffer name is foo<zot>.
This fixes the use case when, for example, 'find-file-hooks'
fails.
* lisp/files.el (find-alternate-file): If buffer 'oname' exists,
kill it before renaming the new one. (Bug#41359)
At least for me, 'auto-save-visited-mode' is very slow and blocks user
interaction for files visited over TRAMP. Therefore, I'd like a
mechanism to disable it for some buffers (namely, those visiting
remote files).
* (auto-save-visited-mode): Document that 'auto-save-visited-mode' can
be set to nil buffer-locally.
* etc/NEWS: Document new behavior.
Add a new function, file-modes-number-to-symbolic.
Make archive-int-to-mode and obsolete alias of it; use it
to define tar-grind-file-mode (Bug#27952).
* lisp/files.el (file-modes-number-to-symbolic): New defun.
* lisp/arc-mode.el (archive-int-to-mode): Make it an obsolete alias.
* lisp/tar-mode.el (tar-grind-file-mode):
Use file-modes-number-to-symbolic.
* test/lisp/arc-mode-tests.el (arc-mode-test-archive-int-to-mode)
* test/lisp/tar-mode-tests.el (tar-mode-test-tar-grind-file-mode):
Update test.
* test/lisp/files-tests.el (files-tests-file-modes-symbolic-to-number)
(files-tests-file-modes-number-to-symbolic): New tests.
* doc/lispref/files.texi (Changing Files): Document the new funtion.
* etc/NEWS (Lisp Changes in Emacs 28.1): Announce it.
* lisp/bookmark.el (bookmark-insert-file-format-version-stamp)
(save-place-alist-to-file): Delimit file-local variables on the -*-
line with semicolons.
* lisp/files.el (auto-mode-alist): Use shy regexp group.
Fixes: bug#40573
The new mode can be used stand-alone or inherited from by modes
intended to edit programs. The existing emacs-lisp-mode and lisp-mode
are examples.
Thanks to Juri Linkov and Basil L. Contovounesios for researching some
data files in Emacs that can be automatically set to use the new mode.
* lisp/files.el (auto-mode-alist): Add entry for ".dir-locals" and
".dir-locals-2"
* lisp/emacs-lisp/lisp-mode.el: (lisp-data-mode): New major mode.
(lisp-mode): Inherit from lisp-data-mode. Set special lisp-mode
stuff here.
* lisp/progmodes/elisp-mode.el (emacs-lisp-mode): Inherit from
lisp-data-mode.
* lisp/bookmark.el (bookmark-insert-file-format-version-stamp):
Use lisp-data-mode.
* lisp/saveplace.el (save-place-alist-to-file): Use
lisp-data-mode.
* lisp/net/eww.el (eww-write-bookmarks): Use lisp-data-mode.
* lisp/net/nsm.el (nsm-write-settings): Use lisp-data-mode.
* lisp/net/tramp-cache.el (tramp-dump-connection-properties): Use
lisp-data-mode.
* etc/NEWS: Mention lisp-data-mode.
* doc/lispref/modes.texi (Example Major Modes): Update example.
This is a companion to the recent set-file-modes patch.
It adds support for a ‘nofollow’ flag to set-file-times (Bug#39773).
Like the set-file-modes patch, it needs work in the w32 port.
* admin/merge-gnulib (GNULIB_MODULES): Add futimens, utimensat.
Remove utimens.
* doc/lispref/files.texi (Changing Files):
* etc/NEWS: Mention the change.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.

when the file is not supposed to be a symbolic link.
* lib/futimens.c, lib/utimensat.c, m4/futimens.m4, m4/utimensat.m4:
New files, copied from Gnulib.
* lisp/gnus/gnus-cloud.el (gnus-cloud-replace-file):
When creating a file that is not supposed to exist already,
use the excl flag to check this.

* lisp/net/tramp-sh.el (tramp-sh-handle-set-file-times):
* lisp/net/tramp-sudoedit.el (tramp-sudoedit-handle-set-file-times):
Accept an optional FLAG arg that is currently ignored,
and add a FIXME comment for it.
* lisp/net/tramp-gvfs.el (tramp-gvfs-handle-set-file-times):
* src/fileio.c (Fset_file_times):
Support an optional FLAG arg.
* src/fileio.c (Fcopy_file): Use futimens instead of set_file_times,
as it’s simpler and is a POSIX API.
* src/sysdep.c (set_file_times): Move from here ...
* src/w32.c (set_file_times): ... to here, and make it static,
since it is now used only in w32.c. Presumably w32.c should also
add support for futimens and utimensat (the POSIX APIs, which
Emacs now uses) and it can remove fdutimens (the Gnulib API,
which Emacs no longer uses).
This avoids some race conditions (Bug#39683). E.g., if some other
program changes a file to a symlink between the time Emacs creates
the file and the time it changes the file’s permissions, using the
new flag prevents Emacs from inadvertently changing the
permissions of a victim in some completely unrelated directory.
* admin/merge-gnulib (GNULIB_MODULES): Add fchmodat.
* doc/lispref/files.texi (Testing Accessibility, Changing Files):

Using the 'dedicated' prop for display-buffer--maybe-at-bottom marks the
window of the buffer "*Process List*" as dedicated, so it won't be replaced
by another buffer that might be visited following links to process buffers
from the buffer "*Process List*".
* lisp/files.el (backup-by-copying-when-privileged-mismatch): In addition
to checking the file uid, a second test is added: if the file gid is not
greater than backup-by-copying-when-privileged-mismatch,
backup-by-copying-when-mismatch will also be forced on.
* doc/emacs/files.texi, doc/lispref/backups.texi: Updated documentation.
Also fixed a typo in the Emacs reference manual, changing "higher" to
"no greater" so that the limit is no longer documented reversed.
* lisp/files.el (insert-directory): Always replace "total" with
"total used in directory", even when we don't have free disk space
(bug#13191). This makes the display more consistent.
* lisp/files.el (move-file-to-trash): Fix file name in
trash-can when another deleted file under the same name is
already stored there. (Bug#37922)
Copyright-paperwork-exempt: yes.
This avoids running doc-view-mode on files that are actually text
files.
* lisp/files.el (auto-mode-alist): Don't use doc-view-mode-maybe
for .doc (but continue to do so for .docx).
(magic-fallback-mode-alist): Add signature for .doc files.
