See Bug#44631. While testing for a readonly output directory has
slightly different semantics, in practice they should cover cases
where Emacs is sandboxed and can only write to the destination file,
not its directory.
* lisp/emacs-lisp/bytecomp.el (byte-compile-file): Handle the case
where the output directory is not writable.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-tests--not-writable-directory)
(bytecomp-tests--dest-mountpoint): New unit tests.
When creating multibyte or unibyte strings, we should guarantee the
following invariants:
- When creating empty strings, a NULL data pointer should be allowed.
This often arises in practice if the string length isn't known in
advance, and we don't want to unnecessarily trigger undefined
behavior. Since functions like memcpy might not accept NULL
pointers, use the canonical empty string objects in this case.
- Nonzero strings should be guaranteed to be unique and mutable.
These are the same guarantees expected from Lisp functions such as
'make-string' or 'unibyte-string'. On the other hand, empty strings
might not be unique.
* src/emacs-module.c (module_make_string)
(module_make_unibyte_string): Correctly handle empty strings.
* test/src/emacs-module-resources/mod-test.c (Fmod_test_make_string):
New test function.
(emacs_module_init): Expose it.
* test/src/emacs-module-tests.el (mod-test-make-string/empty)

corner cases for strings.
* test/src/casefiddle-tests.el (casefiddle-tests-char-casing):
(upcase ?ß) now returns ?ẞ (U+7838), partly for technical reasons but
the previous behaviour was arbitrary and arguably less useful.
Correct upcasing of ß is normally SS, which is what Fupcase returns if
given a string, or (for special purposes) ẞ.
ß was incorrectly treated as a caseless character and thus not matched
by the regexp [[:lower:]] (or, in case-folding mode, [[:upper:]]).
The reason is that the upcase table maps it to itself, which can be
remedied by mapping it to ẞ (U+7838) instead. Doing so does not
affect upcasing since the special-uppercase property maps it to SS.
* lisp/international/characters.el (tbl): Map ß to ẞ in the upcase
table.
* test/src/regex-emacs-tests.el (regexp-eszett): Uncomment previously
failing tests. Add checks to make sure that case transformations
remain valid.

allow expression of a correct predicate for [:upper:] and [:lower:].
(mutually_exclusive_p, re_match_2_internal): Pass extra argument.
* test/src/regex-emacs-tests.el (regexp-case-fold, regexp-eszett):
New tests. Parts of regexp-eszett still fail and are commented out.

The debugger needs to receive a list of the error symbol and data;
cf. the documentation of the `debugger' variable. This bug manifested
itself in ERT forms such as (should (integerp (ert-fail "Boo"))),
which resulted in an incorrect condition object. Note that forms such
as (should (ert-fail "Boo")) weren't affected because they wouldn't
use the `ert--should-signal-hook'.
* test/emacs-lisp/ert.el (ert--should-signal-hook): Call debugger with
the right arguments.
* test/lisp/emacs-lisp/ert-tests.el (ert-test-fail-inside-should): Add
unit test.

printing in batch mode.

already returning integer as generic type.

by the normal syntax tables.

quote of s'foo'bar' as punctuation.
