`unwind-protect` without unwind forms is not just pointless but often
indicates a mistake where the intended unwind part is misplaced, as in
(unwind-protect (progn PROT-FORMS UNWIND-FORMS)) ; oops
or
(unwind-protect PROT-FORM) UNWIND-FORMS ; also oops
or entirely forgotten for that matter. Warning about this makes
sense, and the warning can always be silenced by removing the
`unwind-protect` altogether if it shouldn't be there in the first
place.
* lisp/emacs-lisp/macroexp.el (macroexp--expand-all): Implement
warning.
* etc/NEWS: Announce.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-test--with-suppressed-warnings): Add test case.
* test/Makefile.in (TEST_NATIVE_COMP): New variable, used to
determine whether to run tests tagged with :nativecomp. Set it to
"no" on Cygwin and to $(HAVE_NATIVE_COMP) otherwise.
* test/lisp/emacs-lisp/benchmark-tests.el (benchmark-tests): Skip
on Cygwin with native-compilation.
New shortdoc functions use Unicode arrows when possible, which caused
some tests to fail if run under such circumstances.
* test/lisp/emacs-lisp/shortdoc-tests.el
(shortdoc-tests--to-ascii): New function.
(shortdoc-function-examples-test)
(shortdoc-help-fns-examples-function-test): Call it.
There is no particular requirement for safe-copy-tree so let's make it
internal for now. The new implementation is faster and more correct.
* doc/lispref/lists.texi (Building Lists):
* etc/NEWS: Remove doc and announcement.
* lisp/subr.el (safe-copy-tree--seen, safe-copy-tree--1)
(safe-copy-tree): Remove old version.
* lisp/emacs-lisp/bytecomp.el (bytecomp--copy-tree-seen)
(bytecomp--copy-tree-1, bytecomp--copy-tree): Add new version.
(byte-compile-initial-macro-environment): Use it.
* test/lisp/subr-tests.el (subr--safe-copy-tree):
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp--copy-tree):
Move and improve tests.
* lisp/emacs-lisp/shortdoc.el (shortdoc-help-fns-examples-function):
Implement a better logic to pluralize "Example", by counting the
number of arrow characters in the example string. (Bug#61877)
* test/lisp/emacs-lisp/shortdoc-tests.el
(shortdoc-help-fns-examples-function-test): Add a test.
* lisp/emacs-lisp/shortdoc.el (shortdoc--display-function): Add
a new shortdoc-example text property so that ELisp examples can
be searched for later.
(shortdoc--insert-group-in-buffer): New function extracted from
the buffer insertion code in 'shortdoc-display-group'.
(shortdoc-display-group): Implement in terms of
'shortdoc--insert-group-in-buffer'.
(shortdoc-function-examples): New function that returns an alist
of Emacs Lisp examples from shortdoc.
(shortdoc-help-fns-examples-function): New function to insert
Emacs Lisp function examples in *Help* buffers, if added to
'help-fns-describe-function-functions'.
*
test/lisp/emacs-lisp/shortdoc-tests.el (shortdoc-function-examples-test):
Test it.
* doc/emacs/help.texi (Name Help): Document in the user manual.
* doc/lispref/help.texi (Documentation Groups): Document it.
* etc/NEWS: Advertise it. (Bug#61877)
* lisp/emacs-lisp/cconv.el (cconv-convert): When form is an
interactive lambda form, don't destructively modify it, as it might be
a constant literal. Instead, create a new list with the relevant
place(s) changed.
* test/lisp/emacs-lisp/cconv-tests.el
(cconv-tests-interactive-form-modify-bug60974): New test.
This fixes a bug that miscompiled
(cond ... C S1...Sn)
where S1...Sn are switch clauses (that can be compiled into a switch
op) and C a non-switch clause, by tucking on an extra copy of C at the
end. This was a serious wrong-code bug when the condition of C had
side-effects; otherwise it was only a waste of time and space.
* lisp/emacs-lisp/bytecomp.el (byte-compile-cond): Fix.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test case.
Omitting handlers from a `condition-case` form makes it useless
since no errors are caught.
* lisp/emacs-lisp/macroexp.el (macroexp--expand-all): New warning.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-test--with-suppressed-warnings): Add test case.
* etc/NEWS: Announce.
Add tests for the interaction of `ignore` with warnings.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-warn--ignore): New test.
(bytecomp--with-warning-test): Really make it a function.
Rather than look up a dynamically scoped var to decide whether to trim
closures, use an ad-hoc marker on those closures which should not be trimmed.
* lisp/emacs-lisp/cconv.el (cconv-dont-trim-unused-variables): Delete var.
(cconv-make-interpreted-closure): Use a `:closure-dont-trim-context`
markers instead.
* lisp/emacs-lisp/edebug.el (edebug-make-enter-wrapper): Use
`:closure-dont-trim-context` rather than `cconv-dont-trim-unused-variables`.
* lisp/emacs-lisp/testcover.el (testcover-analyze-coverage): Remove
workaround for `cconv-dont-trim-unused-variables`.
* test/lisp/emacs-lisp/cconv-tests.el (cconv-safe-for-space): New test.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-tests--unescaped-char-literals, test-suppression):
Bind `text-quoting-style` to `grave` around tests to force
generation of ASCII quotes.
* test/src/lread-tests.el (lread-tests--unescaped-char-literals):
Subject the reference string to the same text styling as that
under scrutiny.
Advising interactive forms relies on the ability to distinguish
interactive forms that do nothing else than return a function.
So, be careful to preserve this info.
Furthermore, interactive forms are expected to be evaluated in
the lexical context captured by the closure to which they belong,
so be careful to preserve that context when manipulating those forms.
* lisp/emacs-lisp/cconv.el (cconv-convert, cconv-analyze-form) <lambda>:
Preserve the info that an interactive form does nothing else than
return a function.
* lisp/emacs-lisp/nadvice.el (advice--interactive-form-1): New function.
(advice--interactive-form): Use it.
(advice--make-interactive-form): Refine to also accept function values
quoted with `quote`. Remove obsolete TODO.
* test/lisp/emacs-lisp/nadvice-tests.el: Don't disallow byte-compilation.
(advice-test-bug61179): New test.
* lisp/emacs-lisp/oclosure.el (cconv--interactive-helper): Allow
the `if` arg to be a form.
* lisp/simple.el (oclosure-interactive-form): Adjust accordingly.
* test/lisp/emacs-lisp/shortdoc-tests.el (regexp-opt): Require.
`regexp-opt-charset` is not autoloaded, and whether `regexp-opt` is
preloaded is configuration-dependent.

Add a byte-compiler warning about attempts to compare literal values
with undefined identity relation to other values. For example:
(eq x 2.0)
(memq x '("a" (b) [c]))
Such incomparable values include all literal conses, strings, vectors,
records and (except for eql and memql) floats and bignums.
The warning currently applies to eq, eql, memq, memql, assq, rassq,
remq and delq.
