* lisp/progmodes/cperl-mode.el (cperl-mode): Use
`cperl-font-lock-syntactic-face-function'.
(cperl-commentify): Add a docstring, eliminate unused formal
parameter `noface'.
(cperl-is-here-doc-p): New function to detect whether "<<" starts
a here-document, factored out from `cperl-find-pods-heres'.
(cperl-here-doc-functions): New variable: List of functions which
allow here-documents as parameters, for use in
`cperl-is-here-doc-p'.
(cperl-process-here-doc): New function, factored out from
`cperl-find-pods-heres'. Fixed to keep correct fontification
after non-interactive (elisp) changes (Bug#14343, Bug#28962).
(cperl-find-pods-heres): Extend the doc-string to describe all
parameters. Don't remove text properties in recursive calls on
the same line. Call `cperl-process-here-doc' when appropriate.
(cperl-font-lock-syntactic-face-function): New function to
highlight c-style comments as here-documents (adapted from
perl-mode.el).
* test/lisp/progmodes/cperl-mode-tests.el
(cperl-test-identify-heredoc): New test for the new function
`cperl-is-here-doc-p'.
(cperl-test-identify-no-heredoc): New test for the new function
`cperl-is-here-doc-p', testing constructs which start with "<<"
but are no here-documents.
(cperl-test-here-doc-missing-end): New test to verify correct
detection of a missing here-document delimiter.
(cperl-test-bug-14343): New test to verify that inserting text
into a here-document with elisp does not break fontification.
* lisp/net/tramp-sh.el (tramp-sh-handle-copy-directory): Fix the case
NEWNAME is a directory name with a trailing slash.
* lisp/net/tramp-smb.el (tramp-smb-handle-copy-directory):
Implement `copy-directory-create-symlink'. (Bug#10897)
* test/lisp/net/tramp-tests.el
(tramp--test-ignore-make-symbolic-link-error): Move up.
(tramp-test15-copy-directory): Extend test.
* test/lisp/files-tests.el (files-tests-buffer-offer-save)
(files-tests-save-buffers-kill-emacs--asks-to-save-buffers):
`read-event' is called with arguments.
* test/lisp/custom-tests.el (custom-tests-require-theme): Fix a
native-comp-related test failure.
In this test, we set load-path to nil, and under native-comp some of
the tests want to give a warning:
Warning (comp): Cannot look-up eln file as no source file was
found for /tmp/custom-tests-bfdbkW/custom-tests--d.elc
But we can't load warning.el after setting load-path to nil, so
require it first.
* 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.
* lisp/international/mule-util.el (filepos-to-bufferpos): Give
better errors on `exact' with unknown line endings, and guess at
Unix if `approximate' (bug#36573).
(bufferpos-to-filepos): Ditto.
* doc/misc/tramp.texi (Remote processes): New subsection "Remote
process connection type".
* lisp/net/tramp-adb.el (tramp-adb-handle-make-process):
Use `tramp-process-connection-type' as default connection type.
Improve check for `:connection-type'.
* lisp/net/tramp-sh.el (tramp-sh-handle-make-process):
Use `tramp-process-connection-type' as default connection type.
Improve check for `:connection-type'. Send "stty -icrnl" when
connection type is a pipe.
* lisp/net/tramp.el (tramp-process-connection-type): Allow all
possible values.
(tramp-handle-make-process): Use `tramp-process-connection-type'
as default connection type. Improve check for `:connection-type'.
* test/lisp/net/tramp-tests.el (tramp-test30-make-process): Extend test.
* 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).
* lisp/gnus/nnrss.el (nnrss-get-namespace-prefix): Use the car of
parameter el to match what dom-search expects.
* test/lisp/gnus/nnrss-tests.el (test-nnrss-xml): Adjust to what
xml-parse-region produces (bug#34685).
(cl-generic-generalizers): Remember the specializers that match
a given value.
(cl--generic-eql-generalizer): Adjust accordingly.
* test/lisp/emacs-lisp/cl-generic-tests.el (cl-generic-test-01-eql):
Add corresponding test.
* test/lisp/files-tests.el (files-tests-bug-21454, files-colon-path):
Adapt to change in behavior of 'parse-colon-path'.
* lisp/files.el (parse-colon-path): Don't expand the directory
names: that changes the names in ways this function is not
supposed to. (Bug#49918)
* lisp/progmodes/perl-mode.el: Handle variables first to avoid
conflicting with keywords. This fixes cases like "$package"
(bug#49906).
Copyright-paperwork-exempt: yes
* test/lisp/files-tests.el (files-test-auto-save-name-default)
(files-test-auto-save-name-transform)
(files-test-auto-save-name-unique, files-test-lock-name-default)
(files-test-lock-name-unique): Skip the drive letter in absolute
file names on MS-Windows/MS-DOS when comparing file names against
the expected ones.
(files-tests-file-name-non-special--subprocess): Skip test on
MS-Windows/MS-DOS.
The current method of propagating constants through setq was unsound
because it relied on each setq form only being traversed at most once
during optimisation, which isn't necessarily true in general; it could
be made to miscompile code in rare cases.
Since it was only used in limited circumstances, disabling this
optimisation doesn't cost us much.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-form-code-walker):
Don't update the known value when traversing `setq`.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test case.
Now that ffap-file-finder can be ido-find-file, the
noninteractive portion of find-file-at-point cannot
assume ffap-file-finder always takes an argument
(ido-find-file does not).
* lisp/ffap.el (find-file-at-point): Do not call ffap-file-finder.
* test/lisp/ffap-tests.el (ffap-ido-mode): Test it.
* lisp/emacs-lisp/cl-generic.el (cl-generic-generalizers): Evaluate
forms that are eql specializers. Provide backward compatibility
with a warning.
* test/lisp/emacs-lisp/cl-generic-tests.el: Add a test.
* lisp/emacs-lisp/bindat.el (bindat--type): Adhere to the new rule.

(checkdoc-cl-defmethod-with-types-ok)
(checkdoc-cl-defmethod-qualified-ok)
(checkdoc-cl-defmethod-with-extra-qualifier-ok): Adhere to the new rule.
* etc/NEWS: Describe the change.
* lisp/so-long.el: (so-long-statistics-excessive-p): New predicate
function using `buffer-line-statistics'.
(so-long-predicate): Use `so-long-statistics-excessive-p' by default.
