* doc/emacs/package.texi: Expand documentation and give example.
* etc/NEWS: Mention 'package-vc-selected-packages'.
* lisp/emacs-lisp/package-vc.el (package-vc--select-packages): Remove
function.
(package-vc-ensure-packages): Add function based on
'package-vc--select-packages'.
(package-vc-selected-packages): Call 'package-vc-ensure-packages' from
custom setter.
* lisp/emacs-lisp/text-property-search.el
(text-property--find-end-backward): Don't miss the end of
text-property value at point. This fixes searches backward when
the property is on a single character position. (Bug#58937)
* lisp/emacs-lisp/package.el (package--download-one-archive): Move
'cl-pushnew' call from 'package--download-one-archive' and cons file
name onto the archive.
(package--download-one-archive): Cons the file name onto the archive.
(package--download-and-read-archives): Remove 'cl-pushnew' call.
* lisp/emacs-lisp/package.el (package-load-descriptor): Remove the
:commit check.
The property is mostly unused anyway, and this unnecessarily slows
down initialisation if a package is installed from source.
* 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/emacs-lisp/comp.el (native-comp-debug): Don't emit debug
symbols on MS-Windows. The default was originally made 1 because
without that, C backtraces on Windows would not show
natively-compiled functions correctly, or would even stop short of
reaching the topmost call frame. But that turned out to be due to
a bug in GDB, which was meanwhile fixed in GDB 12. So we can now
reset the value back to zero, and gain smaller *.eln files on
MS-Windows.
This fixes bug #58739. Make subr-arity return, e.g., (12 . 12) rather than
(12 . many) for a function with a fixed number of arguments more than 8.
* lisp/emacs-lisp/comp.el (comp-prepare-args-for-top-level): Only return a cdr
of 'many when there are &rest arguments.
* src/eval.c (eval_sub): Also check for a fixed number of args over 8 when
using the nargs + *args calling convention.
(funcall_subr): Also check numargs <= 8 before using the fixed args calling
convention. Include the case numargs > 8 in the aMany calling convention.
* src/lisp.h (DEFUN): Amend the comment about MANY.
* lisp/emacs-lisp/package-vc.el (package-vc-archive-spec-alist):
Document the feature.
(package-vc-unpack): Check for :vc-backend in both PKG-SPEC and the
archive specification data.
* lisp/emacs-lisp/package-vc.el (package-vc--archives-initialize): Add
new function, extending 'package--archives-initialize'.
(package-vc-install): Use new function.
(package-vc-link-directory): Use new function.
The new code to make interpreted closures safe-for-space introduced
a regression in `cconv-tests-interactive-closure-bug51695`, only seen
when using TEST_LOAD_EL.
A few other issues were found and fixed along the way.
* lisp/emacs-lisp/cconv.el (cconv-fv): Change calling convention and
focus on finding the free variables.
(cconv-make-interpreted-closure): New function.
* lisp/loadup.el: Use `compiled-function-p` rather than
`byte-code-function-p` so we also use safe-for-space interpreted
closures when we build with native compilation.
(internal-make-interpreted-closure-function):
Use `cconv-make-interpreted-closure`.
* src/eval.c (syms_of_eval): Rename `internal-filter-closure-env-function`
to `internal-make-interpreted-closure-function`.
(Ffunction): Let that new var build the actual closure.
* test/lisp/emacs-lisp/cconv-tests.el
(cconv-tests-interactive-closure-bug51695): Test specifically the
interpreted case.
(reb-valid-string): Declare it risky so the mode-line will obey its
text-properties.
(reb-lisp-syntax-p): No need to make it `defsubst`.
(reb-target-value): New function to replace the
`reb-target-binding` macro. Adjust all callers.
(reb-auto-update): Give a more informative error message than just
"invalid" and give it a warning face.
(reb-update-regexp): Always update `reb-regexp-src` (it's harmless),
rather than only when it's necessary (reduces the need for advice in pcre.el).
This adds an option to allow callers to specify that computing
the children of the hierarchy should be delayed to when the
user calls for them, by utilizing the tree-widget :expander
property.
* lisp/emacs-lisp/hierarchy.el (hierarchy-add-tree)
(hierarchy-add-trees): Add parameter 'delay-children-p'.
* lisp/emacs-lisp/hierarchy.el
(hierarchy--create-delayed-tree-widget): Add function.
* lisp/emacs-lisp/hierarchy.el (hierarchy-convert-to-tree-widget):
Utilize ':expander' if delaying children. (Bug#55900)
* test/lisp/emacs-lisp/hierarchy-tests.el: Add tests for
delayed-children functionality.
