* lisp/emacs-lisp/byte-opt.el
(byte-optimize-assq): New.
(byte-optimize-member, byte-optimize-assoc, byte-optimize-memq):
When the list argument is constant nil, the result is always nil.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases):
Add test cases.
* lisp/progmodes/project.el (project--files-in-directory):
Pass "." as the DIR argument to 'find' because otherwise the ignore
expression can match the project root directory name, which we don't
want to happen (bug#50240). Fixup the resulting file names at the end
with concatenation.
Originally I thought it could lead to worse performance, but the
results show equal or slightly better timings.
* lisp/progmodes/xref.el (xref-matches-in-directory):
Apply a similar fix.
(xref--find-ignores-arguments): Use file-name-as-directory, so
that when passed "." replace-match still had the expected effect.
* test/lisp/progmodes/project-tests.el (project-ignores-bug-50240):
New test.
* test/lisp/progmodes/xref-tests.el
(xref-matches-in-directory-filters-with-ignores): New test.
* test/lisp/net/tramp-tests.el
(tramp--test--deftest-direct-async-process): Fix macro declaration.
(tramp-test29-start-file-process, tramp-test30-make-process):
Do not run connection type test for direct async processes.
* doc/emacs/calendar.texi: Document the change.
* lisp/calendar/diary-lib.el (diary-offset):
* test/lisp/calendar/icalendar-tests.el: Add a test (bug#50195).
* test/lisp/emacs-lisp/cl-lib-tests.el (cl-test-caaar)
(cl-test-caadr): Move tests using a cl-lib alias from here...
* test/lisp/subr-tests.el (subr-test-caaar, subr-test-caadr): ...to
here. The functions under test are in subr.el.
* lisp/progmodes/cperl-mode.el (cperl-unwind-to-safe): Replace
(and extend) inline comment by a docstring. Handle edge cases when
inserting text with elisp (related to Bug#28962).
(cperl-process-here-doc): Add syntax-type `here-doc-start'.
(cperl-find-pods-heres): Make sure that the results of this
function are immediately visible.
* test/lisp/progmodes/cperl-mode-tests.el (cperl-test-bug-14343):
Add test cases for "empty" here-documents and inserting at the
edges of a here-document.
* test/lisp/progmodes/cperl-mode-tests.el (cperl--tests-heredoc-face):
New const.
(cperl-test-heredocs, cperl-test-bug-14343): Use it.
(cperl-test-identify-no-heredoc): Remove left-over message.
* 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.
* doc/emacs/files.texi (Auto Save Files): Document it.
* lisp/cus-start.el (standard): Add customize form.
* lisp/files.el (delete-auto-save-files): Move definition to C
(since it's used in the C layer).
* src/buffer.c (Fkill_buffer): Use the new variable (and remove
the old code that apparently didn't trigger for
kill-buffer/delete-auto-save-files.
(syms_of_buffer): Add new variable
kill-buffer-delete-auto-save-files and move definition of
delete-auto-save-files here (bug#21612).
* 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.
