(tramp-sh-handle-make-process, tramp-sh-handle-process-file):

conservative side).

* src/nsterm.m (max_used_fringe_bitmap): Remove unused variable.

Un-obsolete dired-in-this-tree-p and use it again in certain places.

This reverts parts of b425966b07, and 7b50ed553f, i.e. it reverts the
obsoletion of dired-in-this-tree-p and switches some new callers of
file-in-directory-p back to using dired-in-this-tree-p.

It turned out that using file-in-directory-p can be a major
performance regression in case you have a dired buffer of a remote
directory which has become (almost) inaccessible.

Any attempt to open a new dired buffer is checking if a buffer for
that directory already exists (in terms of dired-buffers-for-dir)
which meant that file-in-directory-p was called with the directory of
any existing dired buffer including the inaccessible one where the
file-truename call in file-in-directory-p could block for seconds or
even minutes.

* lisp/dired.el (dired-in-this-tree-p): Undo obsoletion.
(dired-buffers-for-dir): Use dired-in-this-tree-p as before.
* lisp/dired-aux.el (dired-kill-tree,dired-tree-down): Une
dired-in-this-tree-p as before.

Use string-replace instead of replace-regexp-in-string

`string-replace` is easier to understand, less error-prone, much
faster, and results in shorter Lisp and byte code.  Use it where
applicable and obviously safe (erring on the conservative side).

Another fix for parse-colon-path

* test/lisp/files-tests.el (files-tests-bug-21454, files-colon-path):
Adapt to change in behavior of 'parse-colon-path'.

* lisp/files.el (parse-colon-path): Don't expand the directory
names: that changes the names in ways this function is not
supposed to.  (Bug#49918)

Doc update wrt Tramp support of SSH security keys

* doc/misc/tramp.texi (Frequently Asked Questions): Speak about
SSH security keys.
(GVFS-based methods, Predefined connection information)
(Remote shell setup): Fix typo.

* etc/NEWS: Precise Tramp's support for SSH security keys.  Fix typos.

Merge branch 'master' of git.sv.gnu.org:/srv/git/emacs

project.el: Bump the version

* lisp/progmodes/project.el: Bump the version.

Merge branch 'master' of git.sv.gnu.org:/srv/git/emacs

Further fix to filtering Gnus search group names

* lisp/gnus/gnus-search.el (gnus-search-indexed-parse-output): Group
names in the GROUPS argument may be prefixed or not, depending on
which server we're searching, so always enforce prefix policy within
the function.

Fix files-tests broken on MS-Windows by a recent change

* test/lisp/files-tests.el (files-colon-path): Use path-separator, and
account for drive letters in absolute file names on MS-Windows.  (Bug#49918)

Fix prin1 problem in package-quickstart-refresh

* lisp/emacs-lisp/package.el (package-quickstart-refresh): Bind
print-length/print-level before using prin1-to-string (bug#49924).

Fix print-length issue in comp-run-async-workers

* lisp/emacs-lisp/comp.el (comp-run-async-workers): Bind
print-length/print-level to ensure there's no truncation (bug#49922).

Make `q' in `org-agenda' work even with `debug-on-error' set

* lisp/org/org-agenda.el (org-agenda-get-restriction-and-command):
Using `error' here will trigger users with `debug-on-error' so use
`user-error' instead (bug#49920).  It would probably be preferable
to rewrite this to not use the error system to do control flow.

Fix problem with relative directories in CDPATH

* lisp/files.el (parse-colon-path): Allow relative directories
(like ".") in CDPATH (bug#49918).

perl-mode: fix variable fontification

* lisp/progmodes/perl-mode.el: Handle variables first to avoid
conflicting with keywords. This fixes cases like "$package"
(bug#49906).
Copyright-paperwork-exempt: yes

; * lisp/replace.el (occur-1): Remove old fringe arrow.

Allow building on MacOS with MacPorts and libgccjit

* configure.ac: Check for the "port" command (MacPorts).
Add the required lib/include directories for nativecomp.

* src/Makefile.in (LIBGCCJIT_CFLAGS, LIBGCCJIT_LIBS): Split into
two parts to allow including -L/-I for MacPorts.
(LIBES): Adjust.
(EMACS_CFLAGS): Ditto.

Merge from origin/emacs-27

b77f6af24e (origin/emacs-27) ERC right stamps: also use latest buffer...

# Conflicts:

Improve ffap-ido-mode test

* test/lisp/ffap-tests.el (ffap-ido-mode): Actually test
`ido-everywhere' at run time, not compile time (bug#49895).

Fix problem with occasional stalls in `url-retrieve-synchronously'

* lisp/url/url.el (url-retrieve-synchronously): Use
`accept-process-output' on a null process.  That is the safer, more
conventional way of achieving non-blocking sleep-for (bug#49897).

Also rewrite for greater readability.

; * doc/lispref/package.texi (Package Archives): Fix typo.

Mention NonGNU in "Package Archives" node in the manual

* doc/lispref/package.texi (Package Archives): Mention NonGNU, too
(bug#49899).

Add colon-space after prompt

* lisp/progmodes/project.el (project--completing-read-strict):
Fix last change's regression (bug#49865).

Fix automatic hscrolling when line numbers are displayed

* src/xdisp.c (hscroll_window_tree): When line numbers are
displayed, account for the the line-number space when calculating
the desired X coordinate on the left.  (Bug#49891)

Improve wording of recently changed documentation

* src/minibuf.c (syms_of_minibuf):
* lisp/minibuffer.el (minibuffer-restore-windows):
* lisp/progmodes/etags.el (etags-xref-prefer-current-file):
Improve wording of doc strings.

* etc/NEWS: Improve wording and format of recently added entries.

Make sure installed *.eln files have correct permissions

* Makefile.in (install-eln): Add "umask 022" to ensure the *.eln
files are accessible from the user's Emacs session.  Suggested by
Wilhelm Kirschbaum <wkirschbaum@gmail.com>.  (Bug#49864)

ERC right stamps: also use latest buffer's window's width (Bug#44140)

* lisp/erc/erc-stamp.el (erc-insert-timestamp-right): Use latest
buffer's window's width to position the timestamp, if both
`erc-timestamp-right-column' and `erc-fill-column' are not set (or
`erc-fill-mode' is off).  This is what the documentation says, but was
not implemented.  Also fix the bug of using selected window's width
instead of the (or some) window showing the buffer.  The latest
window's width is saved in `erc-timestamp-last-window-width' and used
when the buffer is no more shown.  In case the buffer was never shown,
which I'm not sure can happen, either use `fill-column' if set, or
give up on aligning and just output the timestamp (modulo the kludge)
right after message text.  While here, fix the off by one calculation
of point start when the reference is the window's width.

Change how project-find-file's completion works

* lisp/progmodes/project.el (project--completing-read-strict):
Allow to choose a non-existent file, with confirmation
(bug#49204).
Don't use the string at point as a "real" default, and instead
only include it in "future history": meaning, it will be inserted
on 'M-n' (bug#49865).

New option etags-xref-prefer-current-file

* lisp/progmodes/etags.el (etags-xref-prefer-current-file):
New user option (bug#2544).
(xref-backend-definitions): Use it.

Provide a default for xref-find-apropos pattern

* lisp/progmodes/xref.el (xref-find-apropos):
Provide a default for the pattern (bug#49731).

Change the xref-goto-xref error message

* lisp/progmodes/xref.el (xref-goto-xref):
Change the error message (bug#49846).

Add function minibuffer-restore-windows (bug#45072)

* lisp/minibuffer.el (minibuffer-restore-windows): New function
that removes the completions buffer.  Add it to minibuffer-exit-hook.
* src/minibuf.c (read-minibuffer-restore-windows): Mention
minibuffer-restore-windows.

Reset mtime of a buffer reverted "delicately"

* lisp/files.el (revert-buffer-insert-file-contents-delicately):
Once buffer is reverted, reset its mtime to that of the file.
(Bug#49893)

Fix files-tests on non-Posix systems

* test/lisp/files-tests.el (files-test-auto-save-name-default)
(files-test-auto-save-name-transform)
(files-test-auto-save-name-unique, files-test-lock-name-default)
(files-test-lock-name-unique): Skip the drive letter in absolute
file names on MS-Windows/MS-DOS when comparing file names against
the expected ones.
(files-tests-file-name-non-special--subprocess): Skip test on
MS-Windows/MS-DOS.

Cease attempts to const-propagate through setq

The current method of propagating constants through setq was unsound
because it relied on each setq form only being traversed at most once
during optimisation, which isn't necessarily true in general; it could
be made to miscompile code in rare cases.

Since it was only used in limited circumstances, disabling this
optimisation doesn't cost us much.

* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker):
Don't update the known value when traversing `setq`.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test case.

Fix M-n description in refcards

* etc/refcards/pl-refcard.tex (section{Szukanie przyrostowe}):
Ditto (in comments).

* etc/refcards/refcard.tex (section{Incremental Search}): Fix M-n
description (bug#49872).

; Fix oauth typos in last change.

Add support for the oauth2.el library in nnimap and smtpmail

* doc/misc/gnus.texi (Customizing the IMAP Connection):
* doc/misc/smtpmail.texi (Authentication): Mention it.

* lisp/gnus/nnimap.el (nnimap-login): Support oauth2.

* lisp/mail/smtpmail.el (smtpmail-try-auth-method): New function
for oauth2.

* lisp/cus-start.el (read-minibuffer-restore-windows): Fix entry.

* lisp/vc/smerge-mode.el (smerge-mode-menu): Add menu item for smerge-refine.

Package archive location needs to be absolute filename

* lisp/emacs-lisp/package.el (package--with-response-buffer-1):
Actually check that URL is absolute (bug#49788).

Add a new thing-at-point type: existing-filename

* doc/lispref/text.texi (Buffer Contents): Mention it.

* lisp/thingatpt.el (thing-at-point-file-at-point): New function.
(existing-filename): Register it.

Make `M-j' work reliably if `comment-auto-fill-only-comments' is set

* lisp/simple.el (default-indent-new-line): Force breaking the
line when called interactively (bug#49849).  (Perhaps the
interactive command should be rebound and call this function
instead...)

Improve `define-globalized-minor-mode' doc strings

* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode):
Copy the description from easy-mmode--arg-docstring (bug#49843).

ffap ido accommodation

Now that ffap-file-finder can be ido-find-file, the
noninteractive portion of find-file-at-point cannot
assume ffap-file-finder always takes an argument
(ido-find-file does not).

* lisp/ffap.el (find-file-at-point): Do not call ffap-file-finder.
* test/lisp/ffap-tests.el (ffap-ido-mode): Test it.

Use `abort-minibuffers' in delsel

* lisp/delsel.el (minibuffer-keyboard-quit): Use
`abort-minibuffers' (bug#49821).

Previously, C-g was bound to abort-recursive-edit, now it is bound to
abort-minibuffers.  However, after requiring delsel, it gets bound to
minibuffer-keyboard-quit, which still uses abort-recursive-edit.  Use
the new function instead.

Add new user option 'read-minibuffer-restore-windows'

* doc/lispref/minibuf.texi (Text from Minibuffer): Document it
(bug#45072).

* lisp/cus-start.el (standard): Add.

* src/minibuf.c (syms_of_minibuf): New variable
'read-minibuffer-restore-windows'.

Update outdated Gnus information

* doc/misc/gnus.texi (History): Update information.
