* 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.
