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.
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.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp--with-warning-test): New macro.
(bytecomp-warn-wrong-args, bytecomp-warn-wrong-args-subr):
Use above new macro.
(bytecomp-warn-variable-lacks-prefix): New test.
* test/lisp/emacs-lisp/rx-tests.el (rx-compat): Use with-no-warnings
instead of with-suppressed-warnings which complains when running
the test interactively.
This is a regression from Emacs 26.
Reported by Phillip Stephani.
* lisp/emacs-lisp/rx.el (rx--pcase-transform): Process ? and ?? correctly.
* test/lisp/emacs-lisp/rx-tests.el (rx-pcase): Add test case.
* lisp/emacs-lisp/easy-mmode.el (easy-mmode--arg-docstring):
Only document the values we want to support, not the ones we
actually support.
(define-minor-mode): Partially revert to previous behaviour.
* lisp/emacs-lisp/easy-mmode.el (easy-mmode--arg-docstring):
Clarify when minor modes are switched on/off when called from lisp
(bug#44341).
(define-minor-mode): Make calls from Lisp switch the mode on/off
as documented.
Since a supplied test function can do anything, assoc is not
side-effect-free (bug#44018). However, with only two arguments it is
pure and should be optimised accordingly.
* lisp/emacs-lisp/byte-opt.el (side-effect-free-fns): Remove 'assoc'.
(byte-optimize-assoc): Constant-propagate through 2-arg assoc calls.
* test/lisp/emacs-lisp/bytecomp-tests.el
(byte-opt-testsuite-arith-data): Add test cases.
* lisp/emacs-lisp/unsafep.el:
Add comment explaining the policy for which forms can be considered
'safe' in the sense of unsafep. Remove ones that didn't make the cut:
play-sound-file (large attack surface)
catch, throw (alter program flow, inject data)
replace-regexp-in-string (execute arbitary code)
error, signal (deceptive messages)
* test/lisp/emacs-lisp/unsafep-tests.el (unsafep-tests--unsafe):
Add test cases.
* etc/NEWS: Announce the change.
* lisp/emacs-lisp/text-property-search.el
(text-property-search-forward, text-property-search-backward): Doc fix
to clarify placement of point after search.
* test/lisp/emacs-lisp/text-property-search-tests.el
(text-property-search--pos-test): New defun.
(text-property-search-forward-point-at-beginning)
(text-property-search-backward-point-at-end): New test.
* doc/lispref/modes.texi (Defining Minor Modes): Describe the new
:predicate keyword (bug#44232).
* lisp/emacs-lisp/easy-mmode.el (define-globalized-minor-mode):
Allow a new :predicate keyword.
(easy-mmode--globalized-predicate-p): New function.
* test/lisp/emacs-lisp/bindat-tests.el
(bindat-test-pack/multibyte-string-fails)
(bindat-test-unpack/multibyte-string-fails): Don't use
decode-coding-string.
Problem pointed out by Stefan Monnier <monnier@iro.umontreal.ca>.
* test/lisp/saveplace-tests.el
(saveplace-test-forget-unreadable-files): Use file-truename, to
avoid false negatives when file names are not 'equal' as strings,
but point to the same file.
* test/lisp/emacs-lisp/edebug-tests.el (edebug-tests-with-normal-env)
(edebug-tests-run-macro):
* test/lisp/emacs-lisp/testcover-tests.el
(testcover-tests-markup-region, testcover-tests-run-test-case):
Bind find-file-suppress-same-file-warnings to a non-nil value, to
avoid warnings about "same-file-names", at least on MS-Windows,
due to 8+3 aliases.
* test/lisp/help-fns-tests.el (help-fns-test-lisp-macro)
(help-fns-test-lisp-defsubst):
* test/lisp/emacs-lisp/cl-generic-tests.el
(cl-generic-tests--method-files--finds-methods): Adjust test so
that they work in a symlinked environment (bug#43004).
(cl-generic-tests--method-files--finds-methods): Use file-truename
so that this works in a symlinked environment (bug#43004).
* test/lisp/emacs-lisp/ert-x-tests.el (ert-test-describe-test):
* test/lisp/wdired-tests.el (wdired-test-unfinished-edit-01):
Remove unnecessary compat code; these tests should never need to run
on older versions of Emacs.
* lisp/emacs-lisp/ert-x.el (ert-simulate-keys): New macro.
* test/lisp/international/mule-tests.el
(mule-cmds--test-universal-coding-system-argument): Use it and enable
the test also in batch mode.
* test/lisp/subr-tests.el (subr-test-version-parsing):
* test/lisp/emacs-lisp/gv-tests.el (gv-dont-define-expander-other-file):
* test/src/callint-tests.el (call-interactively/incomplete-multibyte-sequence):
* test/src/emacs-module-tests.el (module/describe-function-1):
Don't fail if curly quotes are in use, as they can be if LC_ALL != C.
It is necessary to make plist-get as a generalized variable, and this
definition allows user to use setf and other useful functions on
plist-get.
* lisp/emacs-lisp/gv.el: Add gv-define-expander for plist-get
* lisp/emacs-lisp/gv-tests.el: Add new tests for plist-get
