* lisp/gnus/gnus-group.el (gnus-group-make-search-group,
gnus-group-read-ephemeral-search-group): If a search is initiated from
a topic line, make sure we get all the groups under that topic (and
under sub-topics).
* lisp/international/ucs-normalize.el
(quick-check-composition-list-to-regexp): Don't add an explicit
pattern for U+1161..U+1175 and U+11a8..U+11c2 since these are already
part of `combining-chars'.
* lisp/net/tramp.el (tramp-handle-write-region):
* lisp/net/tramp-adb.el (tramp-adb-handle-write-region):
* lisp/net/tramp-sh.el (tramp-sh-handle-write-region):
* lisp/net/tramp-smb.el (tramp-smb-handle-write-region): Use `current-time'
if needed.
* lisp/net/tramp-gvfs.el (tramp-gvfs-gio-mapping):
(tramp-gvfs-do-copy-or-rename-file): Remove "gvfs-rename", it is
not trustworthy.
* test/lisp/net/tramp-tests.el (tramp-test07-file-exists-p): Check also for
symlinked files in trash.
(tramp-test20-file-modes): Revert last change, it was a thinko.
* configure.ac: Define harfbuzz_required_ver with required
harfbuzz version, and put it in the warning message emitted when
Cairo is found but not HarfBuzz.
* lisp/progmodes/project.el (project-find-file): Don't say
anything about recognizing file names, as that may lead the user
to think that it'll check whether the string at point is an
existing file (bug#44588).
* src/keymap.c (Fdescribe_buffer_bindings): Fix a call in
describe-buffer-bindings. This fixes a mistake in my previous commit
to prefer the Lisp version of describe-map-tree (8a1441310a), where
0 was accidentally converted to Qt in two places.
* src/minibuf.c (read_minibuf): Avoid crashes in the daemon if the
init file invokes some kind of minibuffer interaction, by not
updating the selected frame if it's the initial frame.
(Bug#44583)
* lisp/dired-aux.el (dired-query): Replace read-char-choice call
with read-char-from-minibuffer.
* lisp/subr.el (read-char-choice): Restore the previous version
that uses read-key.
(read-char-from-minibuffer): Bind help-char to help-form-show
when help-form is non-nil.
* lisp/progmodes/python.el
(python-font-lock-keywords-maximum-decoration): `symbol-name'
should not be quantified by a `+' as it is redundant and performs
very badly (bug#44572).
* lisp/cedet/semantic.el (semantic-submode-list):
(semantic-default-submodes): Remove mention of
global-cedet-m3-minor-mode, which no longer exists, apparently
(bug#44565).
* lisp/progmodes/python.el
(python-font-lock-keywords-maximum-decoration): Fix regular
expressions for font lock of assignments with type hints (bug#44568).
The font lock of assignments with type hints in Python is rather bad.
Consider the following example:
from typing import Mapping, Tuple, Sequence
var1: int = 5
var2: Mapping[int, int] = {10: 1024}
var3: Mapping[Tuple[int, int], int] = {(2, 5): 32}
var4: Sequence[Sequence[int]] = [[1], [1, 2], [1, 2, 3]]
var5: Sequence[Mapping[str, Sequence[str]]] = [
{
'red': ['scarlet', 'vermilion', 'ruby'],
'green': ['emerald green', 'aqua']
},
{
'sword': ['cutlass', 'rapier']
}
]
As things stand right now, only ‘var1’ would be highlighted. To make
things worse, the ‘Mapping’ type hint of ‘var2’ would also be
highlighted, which is entirely incorrect.
This commit makes all of ‘var1’ through ‘var5’ be highlighted
correctly.
* test/lisp/progmodes/cperl-mode-tests.el
(cperl--run-test-cases): New macro, factored out from various
indentation / rewriting tests. Contains documentation of the
format used by the cperl-mode-resources files.
(cperl-test-bug-19709): Replace 'next-line' by 'forward-line'.
(cperl-test-indent-exp),
(cperl-test-indent-styles),
(cperl-test-bug-30393): Use the new macro.
(cperl-test-bug-19709): Make fit for Emacs 26.
(cperl-test-indent-styles): Skip for Perl mode (bug#44561).
(server--create-frame): New function, extracted from
`server-create-dumb-terminal-frame`.
(server-create-window-system-frame, server-create-tty-frame):
(server-create-dumb-terminal-frame): Use it.
(server-create-dumb-terminal-frame): New function.
(server-process-filter): Use it.
(server-delete-client): Don't delete tty terminal when it's not
exclusive to this client.
* lisp/org/org-element.el (org-element-parse-secondary-string):
Don't set buffer-local variables buffer-file-name and buffer-file-truename
in temporary buffer.
* doc/emacs/basic.texi (Inserting Text):
Mention transient input method "iso-transl".
* lisp/leim/quail/latin-ltx.el: Use same Keywords as in other quail files.
Prefer vc-state to benefit from its caching (bug#44534)
This same technique is used in vc-git.el,
per commit 2018-06-28 "Remove extra process call from vc-git-find-file-hook"
93c41ce6aa.
* lisp/vc/vc-hg.el (vc-hg-registered): Use vc-state rather than vc-hg-state.
* lisp/gnus/nnselect.el (nnselect-request-group): If an ephemeral
group is empty, there is nothing to see, so remove the group.
(nnselect-run): Catch and return an empty artlist on error.
You can trigger this rather obscure bug by enabling selective display
if the second glyph in its display vector has an invalid face. For
example, evaluate
(set-display-table-slot standard-display-table
'selective-display [?A (?B . invalid)])
and then enable selective display.
* src/xdisp.c (next_element_from_display_vector): Check whether next
glyph code is valid before accessing it.
* lisp/emacs-lisp/shortdoc.el (sequence): use seq-contains-p instead
of seq-contains, which is obsolete as of 27.1. (Bug#44536)
Copyright-paperwork-exempt: yes
* 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.
