* test/src/comp-tests.el (comp-test-47868-1): Add new test.
* test/src/comp-test-funcs.el (comp-test-47868-1-f)
(comp-test-47868-2-f): New functions.
* lisp/emacs-lisp/comp.el (comp-imm-equal-test): Define new hash
tanble test.
(comp-data-container): Use it.
(comp-final, comp-run-async-workers): have comp required before
reading dumped hashes so that `comp-imm-equal-test' is defined.
In order to correctly detect the case of the "new style" with an empty body,
remove the old optional arguments `init-value`, `lighter`, and `keymap`,
so we can distinguish the "nil arg" from the "absent arg" cases.
Don't bind `load-read-function` to nil but to its actual default value.
Actually, I'm not sure it's worth the trouble rebinding this var, but
if we do, then we should bind it to a valid value rather than to nil.
* lisp/emacs-lisp/edebug.el (edebug--eval-defun): Re-install our advice
if needed.
* lisp/emacs-lisp/map-ynp.el (map-y-or-n-p): Doc fix. (Bug#47833)
* doc/lispref/minibuf.texi (Multiple Queries): Fix the wording in
the description of 'map-y-or-n-p'.
Allow a condition-case handler on the form (:success BODY) to be
specified as the success continuation of the protected form, with
the specified variable bound to its result.
* src/eval.c (Fcondition_case): Update the doc string.
(internal_lisp_condition_case): Implement in interpreter.
(syms_of_eval): Defsym :success.
* lisp/emacs-lisp/bytecomp.el (byte-compile-condition-case):
Implement in byte-compiler.
* lisp/emacs-lisp/cl-macs.el (cl--self-tco): Allow self-TCO
from success handler.
* doc/lispref/control.texi (Handling Errors): Update manual.
* etc/NEWS: Announce.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases)
(bytecomp-condition-case-success):
* test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs--labels):
Add test cases.
This file is needed for CEDET's bootstrap, tho, so we now keep a copy of it
under version control in `gram-wy-boot.el`, very much like we do with
the `ldefs-boot.el` copy of `loaddefs.el`.
* lisp/cedet/semantic/grm-wy-boot.el: Rename from
`lisp/cedet/semantic/grammar-wy.el`.
* lisp/cedet/semantic/grammar.el: Load `grm-wy-boot.el` if
`grammar-wy.el` hasn't been generated yet.
* admin/update_autogen: Also refresh `grm-wy-boot.el`.
* admin/grammars/Makefile.in (WISENT): Add `grammar-wy.el` to the
generated files.
* .gitignore: Add `grammar-wy.el`.
* lisp/emacs-lisp/easy-mmode.el (define-minor-mode):
Use `advertised-calling-convention` to avoid promoting the old
style arguments. Emit a wanring when old-style arguments are used.
Massage the docstring accordingly.
* doc/lispref/modes.texi (Defining Minor Modes): Document the keyword
arguments rather than the old-style positional arguments.
Edebug doesn't deal well with backtracking out of definitions, see
Bug#41988. Rather than trying to support this rare situation (e.g. by
implementing a multipass parser), prevent it by adding an implicit
gate.
* lisp/emacs-lisp/edebug.el (edebug--match-&-spec-op): Disable
backtracking when hitting a &define keyword.
* test/lisp/emacs-lisp/edebug-tests.el
(edebug-tests-duplicate-&define): New unit test.
(edebug-tests--duplicate-&define): New helper macro.
* doc/lispref/edebug.texi (Backtracking): Mention &define in the list
of constructs that disable backtracking.
* etc/NEWS: Document new behavior.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker): Don't
perform incorrect optimisations when a condition-case variable shadows
another lexical variable.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
New test case.
* lisp/emacs-lisp/cl-macs.el (cl--self-tco): Recognise
`condition-case` handlers as being in the tail position.
* test/lisp/emacs-lisp/cl-macs-tests.el (cl-macs--labels):
Extend test.
* lisp/emacs-lisp/seq.el (seq-subseq): Add autoload cookie.
* lisp/eshell/esh-util.el (eshell-sublist): Redefine using seq-subseq
and make obsolete. Update callers.
* lisp/wid-edit.el (widget-sublist): Redefine as obsolete function
alias for seq-subseq. Update callers.
* lisp/emacs-lisp/comp.el (comp-debug): Update docstring and
move default on Windows systems from 0 to 1.
* src/comp.c (Fcomp__compile_ctxt_to_file): Tweak debug
levels.
