At least for me, these tests still occasionally fail.
Do not merge to master.
* test/lisp/emacs-lisp/map-tests.el (test-map-into-hash-test)
(test-map-merge, test-map-merge-with, test-map-merge-empty): Mark as
unstable.
Lambda-lifted variables (ones passed explicitly to lambda-lifted
functions) that are also captured in an outer closure and shadowed
were renamed incorrectly (bug#51982).
Reported by Paul Pogonyshev.
* lisp/emacs-lisp/cconv.el (cconv--lifted-arg): New.
(cconv-convert): Provide correct definiens for the closed-over
variable.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
* test/lisp/emacs-lisp/cconv-tests.el (cconv-tests--intern-all)
(cconv-closure-convert-remap-var): Add tests.
(cherry picked from commit 45252ad8f9)
(dabbrev-expand-test, dabbrev-completion-test)
(dabbrev-completion-test-with-argument):
Use 'kbd' to format keys for 'execute-kbd-macro'.
(dabbrev-expand-test): Fix docstring.
The test signing key succumbed to either expiration or bitrot.
I hope I didn't just publish my secret key to the world.
* test/lisp/emacs-lisp/package-resources/key.pub: Refresh.
* test/lisp/emacs-lisp/package-resources/key.sec: Refresh.
* lisp/emacs-lisp/bytecomp.el
(byte-compile-docstring-length-warn): Warn about overly long
docstring in lambda. (Bug#44858)
(byte-compile--wide-docstring-p): Improve comment.
* test/lisp/emacs-lisp/bytecomp-tests.el
("warn-wide-docstring-defun.el"): Update to test for the above new
warning.
* lisp/emacs-lisp/bytecomp.el (byte-compile--wide-docstring-p):
Ignore more function argument lists.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-tests-byte-compile--wide-docstring-p): New test.
This should really be taken care of by a syntax normalisation step in
the frontend, but there is no such step for non-lexbind code yet.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-letX): Tolerate bindingsa
without initialising expressions.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test cases.
Previously, variables bound outside `while` loops were not substituted
inside even in the absense of mutation. Add the necessary mutation
checking inside loops to allow propagation of values and aliased
variables.
* lisp/emacs-lisp/byte-opt.el
(byte-optimize--inhibit-outside-loop-constprop): New variable.
(byte-optimize-form-code-walker): First traverse each loop without
substitution to discover mutation, then without restrictions.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-test-loop): New.
(bytecomp-tests--test-cases): Add test cases.
* lisp/emacs-lisp/ert.el (ert-deftest):
Evaluate the body of `ert-deftest` with the `lexical-binding` value of
the source file (or more precisely the value in force when the
definition is evaluated), which is what everyone expected, instead of
always using dynamic binding which is what they got until now.
* test/lisp/emacs-lisp/ert-tests.el
(ert-test-deftest-lexical-binding-t): New test.
* lisp/emacs-lisp/lisp-mode.el (lisp-indent-function): Check for
local defforms (`cl-flet' and `cl-labels').
(lisp--local-defform-body): New auxiliary function (bug#9622).
* lisp/emacs-lisp/checkdoc.el (checkdoc-in-abbreviation-p): Use
'forward-ward' instead of 'forward-sexp' to avoid jumping too far in
some situations. (Bug#50731)
* test/lisp/emacs-lisp/checkdoc-tests.el
(checkdoc-tests--abbrev-test): New helper function.
(checkdoc-tests-in-abbrevation-p/basic-case): Rename from
'checkdoc-tests-in-abbrevation-p'.
(checkdoc-tests-in-abbrevation-p/with-parens)
(checkdoc-tests-in-abbrevation-p/with-escaped-parens): Use above new
helper function.
(checkdoc-tests-in-abbrevation-p/single-char)
(checkdoc-tests-in-abbrevation-p/with-em-dash)
(checkdoc-tests-in-abbrevation-p/incorrect-abbreviation): New tests.
* etc/NEWS: Announce new default behavior of map-elt and map-delete
on alists.
* lisp/emacs-lisp/map.el: Bump to version 3.2.
(map-elt): Test alist keys with equal by default. Betray a little
bit more information in the docstring on which functions are used
for which map types. (Bug#47368)
(map-put): Update docstring accordingly.
(map--plist-delete): Consistently test plist keys with eq.
(map-delete): Consistently test alist keys with equal.
* test/lisp/emacs-lisp/map-tests.el (test-map-elt-testfn): Update
for new map-elt behavior.
(test-map-put!-alist, test-map-delete-alist): New tests.
* lisp/emacs-lisp/checkdoc.el (checkdoc-message-text-engine):
Change 'y-or-n-p' check to accept prompt ending with both "? " or "?",
that is, it no longer needs the space. (Bug#50621)
(checkdoc--fix-y-or-n-p): New helper function.
* test/lisp/emacs-lisp/checkdoc-tests.el (checkdoc-tests-fix-y-or-n-p)
(checkdoc-tests-fix-y-or-n-p/no-change)
(checkdoc-tests-fix-y-or-n-p/with-space): New tests.
Replace uses of a variable aliasing another variable with that aliased
variable, to allow for variable removal when possible. This also
enables opportunities for other optimisations. Example:
(let ((y x)) (f y)) => (f x)
The optimisation is only performed if both aliased and aliasing
variables are lexically bound. Shadowing bindings are α-renamed when
necessary for correctness. Example:
(let* ((b a) (a EXPR)) (f a b))
=> (let* ((a{new} EXPR)) (f a{new} a))
* lisp/emacs-lisp/byte-opt.el (byte-optimize--aliased-vars): New.
(byte-optimize-form-code-walker): Cancel aliasing upon mutation.
(byte-optimize--rename-var-body, byte-optimize--rename-var): New.
(byte-optimize-let-form): Add the optimisation.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add relevant test cases.
* lisp/emacs-lisp/byte-opt.el
(byte-optimize-assq): New.
(byte-optimize-member, byte-optimize-assoc, byte-optimize-memq):
When the list argument is constant nil, the result is always nil.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test cases.
* test/lisp/emacs-lisp/cl-lib-tests.el (cl-test-caaar)
(cl-test-caadr): Move tests using a cl-lib alias from here...
* test/lisp/subr-tests.el (subr-test-caaar, subr-test-caadr): ...to
here. The functions under test are in subr.el.
* doc/lispref/sequences.texi (seq-setq): Document this macro.
* lisp/emacs-lisp/seq.el (seq-setq): New macro.
* test/lisp/emacs-lisp/seq-tests.el (test-seq-setq):
Test this macro (bug#50053).
* lisp/emacs-lisp/map.el: Bump version to 3.1.
(map--merge): New merging subroutine that uses a hash table in place
of lists, for both efficiency and avoiding ambiguities (bug#49848).
(map-merge): Rewrite in terms of map--merge.
(map-merge-with): Ditto. This ensures that FUNCTION is called
whenever two keys are merged, even if they are not eql (which could
happen until now). It also makes map-merge-with consistent with
map-merge, thus achieving greater overall predictability.
* etc/NEWS: Announce this weakening of guarantees.
* test/lisp/emacs-lisp/map-tests.el (test-map-merge)
(test-map-merge-with): Don't depend on specific orderings. Test
that nil is correctly merged into a plist.
* doc/lispref/control.texi (Destructuring with pcase Patterns):
Document this macro.
* lisp/emacs-lisp/pcase.el (pcase-setq): New macro. This macro is
the 'setq' equivalent of 'pcase-let'.
* test/lisp/emacs-lisp/pcase-tests.el (pcase-setq): Test this new
macro. (bug#49809).
