* lisp/emacs-lisp/package-vc.el (package-vc--unpack): Raise an error
if the package name is empty.
(package-vc-install): Avoid generating an empty file name, if a URL
ends with a slash, and raise an error if the package name is empty.
* lisp/emacs-lisp/package-vc.el (package-vc--main-file): Check the
:lisp-dir entry in the "extras" of a package description to find the
directory with a main file.
* lisp/emacs-lisp/package-vc.el (package-vc-install-dependencies): Add
new function.
(package-vc--unpack-1): Call 'package-vc-install-dependencies' instead
of 'package-compute-transaction' and 'package-download-transaction'.
It is unreasonable to abort the installation, since we cannot expect
all dependencies to be available in the regular archives. Instead we
note which packages couldn't be found, and warn the user that these
will be missing.
* lisp/emacs-lisp/package-vc.el (package-vc-install-from-checkout):
Set the :dir entry, since `package-vc--unpack-1' assumes the field is
set, as is the case when invoking `package-vc--unpack'.
* lisp/emacs-lisp/package-vc.el (require): Explicitly require cl-lib.
(package-vc--main-file): If the expected file name is missing, try and
find the closest match.
* lisp/emacs-lisp/package-vc.el (package-vc--unpack-1): Call
`package--quickstart-maybe-refresh', just as
`package-install-from-buffer' does. (bug#59728)
* lisp/emacs-lisp/package-vc.el: Replace instances of "source package"
in comments and docstrings.
* lisp/emacs-lisp/package.el: Replace instances of "source package" in
comments and docstrings.
* lisp/emacs-lisp/package-vc.el
(package-vc--generate-description-file): Append a :kind property
instead of modifying the version number.
* lisp/emacs-lisp/package.el (package-desc): Remove special handling
for "vc annotated" versions. (bug#59404)
* lisp/emacs-lisp/package-vc.el (package-vc--main-file): Ensure the
package name is a string.
(package-vc--unpack-1): Use pkg-dir instead of the empty return value
of 'package-lisp-dir'.
(package-vc-install-from-checkout): Fix file name handling.
* lisp/emacs-lisp/package-vc.el (package-vc-update): Ensure that the
command is only invoked with installed packages. that the hook is
always removed and that 'vc-pull' is always called in the right
directory.
* 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'.
* lisp/emacs-lisp/package-vc.el
(package-vc-install-selected-packages): Consider more than just one
value in `package-alist', in case there are multiple installations.
* doc/emacs/package.texi (Fetching Package Sources): Update documentation.
* lisp/emacs-lisp/package-vc.el (package-vc-refresh): Rename from.
(package-vc-rebuild): Rename to.
This intends to clarify the intention and avoid confusion with
'package-refresh-contents'. Thanks to Rudolf Adamkovič for the
suggestion.
* lisp/emacs-lisp/package-vc.el (package-vc-update): Add the source
directory to the identifier list, in case the remaining
'vc-do-command' arguments are all read-time constants.
* lisp/emacs-lisp/package-vc.el (package-vc-repository-store): Remove
obsolete variable.
(package-vc--unpack-1): Respect :lisp-dir.
(package-vc--unpack): Add :lisp-dir to the package description if
necessary.
* lisp/emacs-lisp/package.el (package--delete-directory): Check if a
directory is a symbolic link.
