* doc/emacs/maintaining.texi (VC Change Log):
Add 'C-x v b l' (vc-print-branch-log).
(Creating Branches): Add @kindex and @findex for vc-create-branch.
(Switching Branches): Add @kindex and @findex for vc-switch-branch.
* lisp/vc/vc-hooks.el (vc-menu-map): Add menu items for new
commands vc-create-branch and vc-switch-branch, and also
vc-print-branch-log.
* lisp/vc/vc.el (vc-print-branch-log): Improve docstring.
* lisp/vc/vc.el (vc-checkout): Try to use the vc-dir's backend
before looking for the file's one. The latter doesn't work when
the file doesn't exist on disk yet (bug#62674).
* lisp/vc/ediff-init.el (ediff-window-display-p): Document how to
prevent Ediff from creating additional frames, now that this
function can no longer be used or advised for that. (Bug#61850)
* lisp/vc/vc-dispatcher.el (vc-resynch-window, vc-resynch-buffer):
While comparing with `buffer-file-name' if `file' is not absolute
use `expand-file-name' in `vc-root-dir'. This fixes the case of
refreshing the buffers after typing `C-x v = C-x v u' (bug#60897).
* lisp/vc/vc-git.el (vc-git--pushpull): Add comment.
* lisp/vc/vc.el (vc-pull-and-push): Expand docstring about
prerequisites for backend to support this command (bug#60569).
* lisp/vc/vc-git.el (vc-git-pull-and-push): Remove and move its logic to
vc-pull-and-push.
* lisp/vc/vc.el (vc-pull-and-push): Add code from vc-git-pull-and-push.
(vc-dir-mode-map): Replace ‘%’ for vc-dir-mark-by-regexp
with ‘% m’ in regexp-map and ‘* %’ in mark-map (bug#60887).
* doc/emacs/maintaining.texi (VC Directory Commands): Replace ‘%’
with ‘% m’ and ‘* %’. Mention vc-dir-mark-registered-files.
"ESC" looks like an attempt to use kbd syntax in customization.
But actually now 'key-description' is used in 'diff-minor-mode-map'
to convert "\e" to "ESC".
* lisp/vc/vc-git.el (vc-git-checkin): Don't try to apply an empty
patch to the index, because in that case 'git apply' fails.
(cherry picked from commit 1424342225)
* lisp/cedet/semantic/complete.el (semantic-displayer-show-request):
* lisp/descr-text.el (describe-char-categories):
* lisp/mh-e/mh-identity.el (mh-select-identity):
* lisp/transient.el (transient--delay-post-command)
(transient--post-command):
* lisp/vc/vc-git.el (vc-git-create-tag):
* test/lisp/emacs-lisp/cl-lib-tests.el
(cl-lib-nth-value-test-multiple-values):
* lisp/emulation/viper-cmd.el (viper-preserve-cursor-color):
Use `equal` instead of `eq` and `member` instead of `memq` where
the comparison is with literals without guaranteed identity.
In some cases this change corrects evident bugs, in others it is
mostly cosmetic.
* lisp/vc/vc.el (vc-deduce-fileset-1): Don't call diff-vc-deduce-fileset
for diff-mode when buffer-file-name is non-nil. This is because in this case
a file with a diff might be committed to VCS. So don't use it as a patch
to commit with 'C-x v v'.
* lisp/emacs-lisp/package-vc.el (package-vc-prepare-patch): Use
'vc-prepare-patch-prompt-revisions'.
* lisp/vc/vc.el (vc-prepare-patch-prompt-revisions): Extract common
function and handle prefix arguments.
(vc-prepare-patch): Pull logic out to
'vc-prepare-patch-prompt-revisions'.
Hunks were not computed correctly because the diff3 command was
invoked with arguments in an incorrect order. The correct order is
the local file first, the base (or "ancestor") second and the other
file third. This erroneous behavior had two consequences. First, the
output of diff3 would change, since it tries to merge chunks according
to maximal matches between the second and first files, and the second
and third files. Second, ediff, more precisely, `ediff-do-merge',
would consequently try to merge the reverse of the changes from the
base to the other file.
* lisp/vc/ediff-diff.el (ediff-setup-diff-regions3): In the arguments
to `ediff-exec-process', swap the other file with the ancestor (only
when merging with an ancestor).
(ediff-extract-diffs3): Match the hunk data for the ancestor and the
other file correctly. The local variable `three-way-comp' indicates
this is a merge with ancestors when it is nil.
(Bug#59182)
* lisp/emacs-lisp/package-vc.el (package-vc-release-rev): Use new
signature.
* lisp/vc/vc-git.el (vc-git-last-change): Update signature
* lisp/vc/vc.el (vc-default-last-change): Update signature and use
'annotate-command'.
* lisp/emacs-lisp/package-vc.el (package-vc-archive-spec-alist):
Unmention :release-rev
(package-vc-desc->spec): Fall back on other archives if a
specification is missing.
(package-vc-main-file): Add new function, copying the behaviour of
elpa-admin.el.
(package-vc-generate-description-file): Use 'package-vc-main-file'.
(package-vc-unpack): Handle special value ':last-release'.
(package-vc-release-rev): Add new function using 'last-change'.
(package-vc-install): Pass ':last-release' as REV instead of a
release.
* lisp/vc/vc-git.el (vc-git-last-change): Add Git 'last-change'
implementation.
* lisp/vc/vc.el (vc-default-last-change): Add default 'last-change'
implementation.
This attempts to replicate the behaviour of elpa-admin.el's
"elpaa--get-last-release-commit".
* lisp/vc/vc.el (vc-default-checkin-patch):
Call vc-revert-file on buffer-file-name (vc-backend failed on
relative name sometimes). Delete the tmp dir after copying all
files back, not just the first one. Bug#52349,
https://lists.gnu.org/archive/html/emacs-devel/2022-10/msg01446.html.
