* lisp/progmodes/cc-styles.el (c-set-style): Use kill-local-variable rather
than copying the hook's global value to the local binding.
(c-make-styles-buffer-local): Remove redundant make-variable-buffer-local.
* lisp/gnus/mml-sec.el (mml-secure-epg-sign): Partially revert
"Make mml-secure-epg-sign bug out if we can't find an identity".
It causes signing to fail for people who have not set up
mml-secure-{smime,openpgp}-sign-with-sender, which is a regression
from Emacs-26 (Bug#40118). In such a situation gpg will use its
default key.
Do not merge to master. On master Emacs will query the user.
The calculation of business days was broken in 2012 (probably
310e60d945 or thereabouts) when the date representation changed
epoch so that Jan 1, 1 AD became day number 1 instead of 0. Repair
this, along with an unrelated bug that prevented arbitrary holiday
weekdays from working.
Reported by Aaron Zeng.
* lisp/calc/calc-forms.el (math-to-business-day)
(math-from-business-day): Correct calculation of weekdays using Calc's
current (Rata Die) chronology. Modify loop condition to cope with odd
sets of holiday weekdays.
* test/lisp/calc/calc-tests.el (calc-business-days): New test.
Tag all native compiler tests and skip them in vanilla builds
* test/Makefile.in (SELECTOR_DEFAULT, SELECTOR_EXPENSIVE)
(SELECTOR_ALL): Define selectors for vanilla or nativecomp builds.
* test/src/comp-tests.el: Do not native compile test files on
vanilla.
(comp-deftest): New macro to define tests tagging as :nativecomp.
* lisp/ebuff-menu.el (electric-buffer-list): Ensure that point is
restored, which isn't always the case if
global-display-line-numbers-mode (bug#43755). This enables
selecting buffers again.
* lisp/progmodes/python.el (python-shell-send-statement): Don't
send a cookie, because that leads to the naked expression not
being evaled (bug#43450).
(python-shell-send-region): Allow not sending a cookie.
(python-shell-buffer-substring): Ditto.
* doc/lispref/loading.texi (Autoload): Document change of name
(bug#39823).
* lisp/emacs-lisp/autoload.el (autoload-find-generated-file): Pass
the file name in.
(autoload-generated-file): Ditto.
(autoload-file-load-name): Ditto.
(generate-file-autoloads): Ditto.
(autoload--setup-output): Ditto.
(autoload-generate-file-autoloads): Ditto, and alter doc string to
reflect when `generated-autoload-file' is heeded.
(update-file-autoloads): Pass outfile in to functions.
(autoload-find-destination): Ditto.
(update-directory-autoloads): Make into an obsolete shim around
`make-directory-autoloads'.
(make-directory-autoloads): Renamed from
`update-directory-autoloads' with new semantics.
(batch-update-autoloads): Adjust caller.
* lisp/emacs-lisp/package.el (package-generate-autoloads): Adjust
caller.
* lisp/wdired.el (wdired-do-perm-changes) Use set-file-modes
instead of external program (bug#39284). This fixes the problem
of passing the wrong argument to the external chmod.
* test/src/syntax-tests: Add a new section testing some aspects of comment
handling in syntax.c. This needs further enhancement. It uses ....
* test/data/syntax-comments.txt: A new test file.
* lisp/isearch.el (isearch-group-odd, isearch-group-even): New faces
instead of isearch-group-1 .. isearch-group-9.
(isearch-highlight): Use new faces.
* lisp/progmodes/sql.el (sql-add-product): Re-correct argument
spec. Previous change was due to my mistake; I have
resolved back to the prior behavior (Bug#39960).
* test/lisp/progmodes/sql-tests.el (sql-test-add-product): Added
test to insure I don't make the same mistake again.
* lisp/emacs-lisp/backtrace.el (backtrace--to-string): New function.
(backtrace-to-string): Use it. Fix whitespace (bug#40728).
* lisp/emacs-lisp/debug.el (debugger-insert-backtrace): New function.
Mark it as obsolete.
(debugger-toggle-locals, debug-help-follow): New aliases.
* lisp/simple.el (visual-line-mode): Only save values once, even
if the mode is switched on twice (bug#43730). This makes both
previously set local values for variables like truncate-lines, as
well as default values for truncate-lines restorable.
* lisp/emulation/cua-base.el (cua-mode): Ditto.
* lisp/gnus/mml-sec.el (mml-secure-sender-sign-query): New
function (bug#40118).
(mml-secure-epg-sign): Use it to determine the signer (bug#40118).
* lisp/gnus/mml-sec.el
(mml-secure-allow-signing-with-unknown-recipient): Remove.
* src/xdisp.c (restore_selected_window): Fix the more grave
problems caused by a function deleting the previously selected
frame or window (bug#39977).
AFAICT, in ttys you can send a `C-_` to Emacs either by pressing
`C-/` (e.g. xterm, uxterm, rxvt, xfce4-terminal, gnome-terminal)
or by pressing `C--` (e.g. rxvt, Linux console).
* epa-mail.el (epa-mail-offer-skip): New option.
(epa-mail-encrypt): If epa-mail-offer-skip is nil,
don't offer to skip a keyless recipient, just cause error.
