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/cl-macs.el (cl-case): Check that the case is of the
form (quote FOO), not just (quote).
* test/lisp/emacs-lisp/cl-macs-tests.el (cl-case-no-warning): New unit test.
* test/lisp/emacs-lisp/bytecomp-tests.el
("warn-wide-docstring-ignore-function-signature.el"): New test.

Make regexp more allowing to silence warning.

New file.
* lisp/emacs-lisp/cl-macs.el (cl-case): Warn if the user passes a nil
key list (which would never match). Warn about quoted symbols that
should probably be unquoted.
* test/lisp/emacs-lisp/cl-macs-tests.el (cl-case-warning): New unit
test (bug#51368).
* lisp/emacs-lisp/cl-macs.el (cl-case): Warn if the user passes a nil
key list (which would never match). Warn about quoted symbols that
should probably be unquoted.

test (bug#51368).
* lisp/emacs-lisp/ert-x.el (ert-with-test-buffer-selected): New
convenience macro that extends `ert-with-test-buffer' by displaying
the test buffer in a temporary selected window. This makes it easier
to simulate user input in the body via `execute-kbd-macro'.
* test/lisp/emacs-lisp/ert-x-tests.el
(ert-test-test-buffer-selected/*): Add tests.
* lisp/emacs-lisp/backtrace.el (backtrace-mode-map): Don't bind
the "s" command, because it's meaningless outside modes that have
set the backtrace-goto-source-functions variable (and only edebug
does that) (bug#57674).
* lisp/emacs-lisp/edebug.el (edebug-pop-to-backtrace): Use it.
(edebug-backtrace-mode-map, edebug-backtrace-mode): New mode.
The recent fix for bug#57397 introduced a regression, breaking
the `cl-lib-symbol-macrolet-hide` test. It turned out that the
origin of the problem was that `gv.el` uses `macroexpand-1` which
does not (can't) use `macroexpand` but `cl-symbol-macrolet` failed
to advise `macroexpand-1` the way it advised `macroexpand`.
To fix this, we change `cl-symbol-macrolet` so it advises both, and we
do that with a new `macroexpand` advice which delegates the bulk of
the work to `macroexpand-1`.
Along the way, I bumped into another bug in the interaction between
`cl-letf` and `cl-symbol-macrolet`, which I tried to fix in `cl-letf`.
I hear the war on `cl-symbol-macrolet` was a failure.
Maybe ... just say no?
* lisp/emacs-lisp/cl-macs.el (cl--sm-macroexpand-1): New function,
extracted from `cl--sm-macroexpand`.
(cl--sm-macroexpand): Rewrite completely.
(cl-symbol-macrolet): Advise both `macroexpand` and `macroexpand-1`.
(cl--letf): Don't use the "simple variable" code for symbol macros.

Revert last change because the test was right.

* lisp/emacs-lisp/cl-macs.el (cl--letf): Remove workaround placed to
try and handle symbol macros.

Add new testcase.
* lisp/emacs-lisp/lisp-mode.el (lisp-current-defun-name): Use
edebug specs to find the name (if they exist), and default to

(bug#49592).

* test/lisp/emacs-lisp/icons-tests.el: Add some tests.
* lisp/emacs-lisp/seq.el (seq-subseq):
Make faster by using `take` instead of a lisp loop,
and more importantly by not front-loading the error text formatting.

(test-seq-subseq): Test `seq-subseq` for lists more thoroughly.
* lisp/emacs-lisp/subr-x.el (string-limit): Return more correct
results in the CODING-SYSTEM case for coding systems with BOM and
charset designations (bug#48324). Also amend the algorithm to
return complete glyphs, not just complete code points.
* test/lisp/emacs-lisp/text-property-search-tests.el
(text-property-search-forward/point-at-beginning)
(text-property-search-backward/point-at-end): Rewrite to make tests
easier to read.
* lisp/sqlite-mode.el (require):
* lisp/net/eudc.el (require):
* lisp/arc-mode.el (require): Require subr-x, since these files
are using macros from there.
* lisp/emacs-lisp/subr-x.el (with-memoization): Move from here...
* lisp/subr.el (with-memoization): ... to here, as it's used from
the preloaded cl-generic.el file.
* lisp/emacs-lisp/cl-generic.el (cl--generic-compiler): Don't use
the autoloaded `byte-compile' function during bootstrap.
(cl--generic-get-dispatcher): Don't require subr-x, either.
cl-generic has been preloaded since 2015, and most usages of it (in
preloaded files) work fine. In particular, using `cl-defgeneric' is
unproblematic. However, `cl-defmethod' would end up pulling in the
byte compiler (at load time), which would make it impossible to use
`cl-defmethod' in pre-loaded files, and this change fixes that (but
possibly not in the most self-evidently correct way).
* lisp/emacs-lisp/bindat.el (bindat--pack-strz): For fixed-length strz
fields, explicitly write a null terminator after the packed string if
there is room (bug#56048).

if 'no-byte-compile' is set.

file.

Omit the reversal of the returned list. It is not ordered anyway.

(subr-x--hash-table-keys-and-values): New test.
Doc strings, `declare` and `interactive` forms must appear in that
order and at most once each. Complain if they don't, instead of
silently ignoring the problem (bug#55905).
* lisp/emacs-lisp/byte-run.el (byte-run--parse-body)
(byte-run--parse-declarations): New.
(defmacro, defun): Check for declaration well-formedness as

New test.
* lisp/emacs-lisp/bindat.el (bindat--pack-strz): Explicitly write a
null byte after packing a variable-length string to ensure proper
termination when packing to a pre-allocated string.

Update tests.
Early normalisation of setq during macroexpand-all allows later
stages, cconv, byte-opt and codegen, to be simplified and duplicated
checks to be eliminated.
* lisp/emacs-lisp/macroexp.el (macroexp--expand-all):
Normalise all setq forms to a sequence of (setq VAR EXPR).
Emit warnings if necessary.

New files.

attempts to pack a multibyte string containing characters other than
ASCII and `eight-bit' characters (bug#55897).

Don't transpose doc string and interactive spec, which must come
in this order.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-function-attributes): New test.
* lisp/emacs-lisp/find-func.el (find-function-advised-original): Look
at the actual function definition rather than
`advice--symbol-function` which sometimes returns only the advice.

(test-byte-comp-compile-and-load): Add lexical cookie to file being
compiled as part of the test.
(bytecomp-test--with-suppressed-warnings): Comment out the test
for suppressing warnings when attempting to let-bind `nil`,
