* lisp/emacs-lisp/package-vc.el (package-vc-unpack-1): Add new function.
(package-vc-unpack): Use 'package-vc-unpack-1'.
(package-vc-link-project): Add new command.
* lisp/emacs-lisp/package-vc.el (package-vc-unpack): Check if the
upstream data indicates a custom lisp directory.
* lisp/emacs-lisp/package.el (package--delete-directory): Adapt
accordingly.
* lisp/emacs-lisp/package-vc.el (package-vc-fetch): Rename to preserve
symmetry with 'package-install'.
(package-checkout): Follow the previous rename.
* lisp/emacs-lisp/package-vc.el (package-vc-repository-store): Add new
user option.
(package-vc-unpack): Use 'package-vc-repository-store'.
* lisp/emacs-lisp/package.el (package--delete-directory): Check and
handle source packages.
(package-delete): Invoke 'package--delete-directory' with an
additional argument.
* package-vc.el (package-vc-probable-repository-regexp): Rename to
'package-vc-heusitic-alist'.
(package-vc-heusitic-alist): Add support for multiple VC backends.
(package-vc-sourced-packages-list): Use 'package-vc-heusitic-alist'
* package.el (eval-when-compile): Require 'inline during compilation.
(package-vc-p): Add inline function.
(package-desc-full-name): Use it.
(package-load-descriptor): Use it.
(package--get-activatable-pkg): Use it.
(package-install-from-archive): Use it.
(package-update): Use it.
(package-desc-status): Use it.
(package--remove-hidden): Use it.
(package-menu--print-info-simple): Use it.
* lisp/emacs-lisp/package.el (package-reinstall): call
`package--archives-initialize', just like `package-install' does.
This populates `package-alist', and so fixes calling
`package-reinstall' as the first thing done after package "quick
init" (Bug#53527).
* doc/lispref/compile.texi (Native-Compilation Variables):
Document it.
* lisp/startup.el (normal-top-level): Set
inhibit-native-compilation from environment variable.
* lisp/subr.el (native-comp-deferred-compilation): Make obsolete.
* lisp/emacs-lisp/comp.el (comp-trampoline-compile): Don't write
trampolines to disk.
* lisp/progmodes/elisp-mode.el
(emacs-lisp-native-compile-and-load): Adjust.
* src/comp.c (syms_of_comp): New variable
inhibit-native-compilation.
(maybe_defer_native_compilation): Use it.
* lisp/emacs-lisp/ert-x.el (ert-with-test-buffer-selected): Set
`inhibit-read-only' and `buffer-read-only' to nil when executing the
body to provide a more realistic test environment.
* lisp/emacs-lisp/byte-opt.el (byte-opt--bool-value-form):
`set` is boolean identity in its second argument.
(byte-compile-trueconstp): `set-marker` is always true.
* lisp/emacs-lisp/ert-x.el (ert-with-temp-file): Add new keyword
argument :buffer SYMBOL to visit the file with `find-file-literally'
before running the body, and cleaning up after.
* lisp/emacs-lisp/nadvice.el:
* lisp/emacs-lisp/cl-generic.el: Don't push to
package--builtin-versions "manually", because loaddefs-gen does
this correctly now.
Make cconv.el detect when a closure's interactive form needs to
capture variables from the context and tweak the code accordingly
if so.
* lisp/emacs-lisp/cconv.el (cconv--interactive-form-funs): New var.
(cconv-convert): Handle the case where the interactive form captures
vars from the surrounding context. Remove left over handling of
`declare` which was already removed from the cconv-analyze` phase.
(cconv-analyze-form): Adjust analysis of interactive forms accordingly.
* lisp/emacs-lisp/oclosure.el (cconv--interactive-helper): New type and
function.
* lisp/simple.el (function-documentation, oclosure-interactive-form):
Add methods for it.
* test/lisp/emacs-lisp/cconv-tests.el
(cconv-tests-interactive-closure-bug51695): New test.
Only perform the rewrite
(set 'VAR X) -> (setq VAR X)
for dynamic variables, as `set` isn't supposed to affect
lexical vars (and never does so when interpreted).
* lisp/emacs-lisp/byte-opt.el (byte-optimize-set):
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--xx): New.
(bytecomp-tests--test-cases): Add test cases.
* test/lisp/emacs-lisp/bytecomp-resources/warn-variable-set-nonvariable.el:
Remove obsolete test.
* lisp/emacs-lisp/lisp-mode.el (lisp-mode--search-key): New
function to check more carefully for start of :keywords and
&options (bug#51574).
(lisp-fdefs): Use it.
