* 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 The default was originally made 1 because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.
* lisp/emacs-lisp/package-vc.el (package-vc-archive-spec-alist):
Update docstring.
(package-vc-install): Use :release-rev if invoked with a prefix argument.
Interpreted closures currently just grab a reference to the complete
lexical environment, so (lambda (x) (+ x y)) can end up looking like
(closure ((foo ...) (y 7) (bar ...) ...)
(x) (+ x y))
where the foo/bar/... bindings are not only useless but can prevent
the GC from collecting that memory (i.e. it's a representation that is
not "safe for space") and it can also make that closure "unwritable"
(or more specifically, it can cause the closure's print
representation to be u`read`able).
Compiled closures don't suffer from this problem because `cconv.el`
actually looks at the code and only stores in the compiled closure
those variables which are actually used.
So, we fix this discrepancy by letting the existing code in `cconv.el` tell
`Ffunction` which variables are actually used by the body of the
function such that it can filter out the irrelevant elements and
return a closure of the form:
(closure ((y 7)) (x) (+ x y))
* lisp/loadup.el: Preload `cconv` and set
`internal-filter-closure-env-function` once we have a usable `cconv-fv`.
* lisp/emacs-lisp/bytecomp.el (byte-compile-preprocess): Adjust to new
calling convention of `cconv-closure-convert`.
(byte-compile-not-lexical-var-p): Delete function, moved to `cconv.el`.
(byte-compile-bind): Use `cconv--not-lexical-var-p`.
* lisp/emacs-lisp/cconv.el (cconv--dynbound-variables): New var.
(cconv-closure-convert): New arg `dynbound-vars`
(cconv--warn-unused-msg): Remove special case for `ignored`,
so we don't get confused when a function uses an argument called
`ignored`, e.g. holding a list of things that it should ignore.
(cconv--not-lexical-var-p): New function, moved from `bytecomp.el`.
Don't special case keywords and `nil` and `t` since they are already
`special-variable-p`.
(cconv--analyze-function): Use `cconv--not-lexical-var-p`.
(cconv--dynbindings): New dynbound var.
(cconv-analyze-form): Use `cconv--not-lexical-var-p`.
Remember in `cconv--dynbindings` the vars for which we used
dynamic scoping.
(cconv-analyze-form): Use `cconv--dynbound-variables` rather than
`byte-compile-bound-variables`.
(cconv-fv): New function.
* src/eval.c (Fsetq, eval_sub): Remove optimization designed when
`lexical-binding == nil` was the common case.
(Ffunction): Use `internal-filter-closure-env-function` when available.
(eval_sub, Ffuncall): Improve error info for `excessive_lisp_nesting`.
(internal-filter-closure-env-function): New defvar.
* lisp/tab-bar.el (tab-bar--load-buttons): Use 'define-icon' to
define icons for tab-bar-new, tab-bar-close, tab-bar-menu-bar.
Also set tab-bar-new-button, tab-bar-close-button, tab-bar-menu-bar-button
to the specified icon-string.
(tab-bar-history-mode): Use 'define-icon' to
define icons for tab-bar-back, tab-bar-forward.
Also set tab-bar-back-button, tab-bar-forward-button
to the specified icon-string.
* lisp/emacs-lisp/icons.el (icons--create)<image>: Allow to easy
add new image props by using 'apply' on them. Add :margin.
* lisp/emacs-lisp/package-vc.el (package-vc-guess-backend): New
function.
(package-vc-unpack): Use it.
(package-vc-sourced-packages-list): Use it.
(package-vc-install): Use it.
