* test/lisp/erc/erc-join-tests.el
(erc-join-tests--autojoin-channels-ident): Be more flexible in checking
assertion.  (Bug#79017)

* lisp/progmodes/python.el (python-indent-dedent-line-backspace):
Delete the text in the region if Transient Mark mode is enabled,
the mark is active, and prefix arg is 1.  (Bug#48695)

* test/lisp/progmodes/python-tests.el
(python-indent-dedent-line-backspace-4): Add new test.

When building a query string via `url-build-query-string',
%-encode literal % characters appearing in both the keys and
the values.
* lisp/url/url-util.el (url--query-key-value-preserved-chars):
Define a new constant based on `url-query-key-value-allowed-chars'
specifying the characters that should be preserved when %-encoding
query-string keys and values.
(url-build-query-string): Use the new constant (fixes Bug#78984).

* test/lisp/url/url-util-tests.el (url-util-tests): Add a test.

* lisp/net/tramp-smb.el (tramp-smb-handle-file-attributes):
Use `directory-file-name'.

* test/lisp/net/tramp-tests.el (tramp-test18-file-attributes)
(tramp-test19-directory-files-and-attributes): Extend tests.

* test/lisp/erc/erc-join-tests.el
(erc-join-tests--autojoin-channels-ident): A `sleep-for' value of 0.01
caused associated tests to fail on at least one setup involving Solaris
10.  The new value is arbitrary and possibly temporary, pending further
investigation.  (Bug#79017)

* lisp/progmodes/cperl-mode.el (cperl--sub-name-generated-rx):
Simplify captures to account for the :writer attribute.  Parsing
is done later.

accessors (in grammar.pl)

Remove unused function.

* lisp/erc/erc-join.el (erc-autojoin-channels-delayed): Only cancel
`erc--autojoin-timer' in the server buffer in which it's local.  After
Emacs 28 brought commit fc66ec33226aeed0b745356363ed952c8ff1f7fd "Prefer
defvar-local in erc", customizing `erc-autojoin-timing' to `ident' led
to ERC emitting redundant JOINs before `erc-autojoin--join' was factored
out.  Additionally, don't bother binding options around the call to
`erc-autojoin-channels' to shape its behavior, preferring instead to
call the internal workhorse function directly.  Ever since bug#5521
introduced those options, the logic in `erc-autojoin-channels' has
ignored `erc-autojoin-delay' anyway, so long as `erc-autojoin-timing'
isn't `ident'.  This change may break third party advice.
(erc-autojoin-after-ident): Restore code to cancel timer.  It was
erroneously deleted in 959fbcf34b5dd04e1b4bf87c0b73afd784a41f7f "favor
network identities in erc-join".
* test/lisp/erc/erc-join-tests.el: Require erc-tests-common atop file so
tests can take advantage of common utilities.
(erc-autojoin-channels--connect): Replace with a function and three
separate tests.
(erc-join-tests--autojoin-channels-connect): New function.
(erc-autojoin-channels/server, erc-autojoin-channels/network)

(erc-tests-common-init-server-proc): Use `make-process' instead of
`start-process'.
(erc-tests-common-make-server-buf): Use `erc-server-current-nick' to
create the `erc-networks--id' as a `erc-networks--id-qualifying'
instance, which is more realistic than a "fixed" variant.
