* test/lisp/replace-tests.el (replace-tests-with-undo):
When testing the "U" (undo all changes) option, the code will delay
and ding which is obnoxious in an automated test.
Disabling that makes the test quiet and about 150 times faster.
* lisp/progmodes/gdb-mi.el (gdb-registers-enable-filter)
(gdb-registers-filter-pattern-list): New custom options.
(gdb-header-click-event-handler, gdb-registers-toggle-filter): New
functions.
(gdb-header-click-event-handler): Only add a register if it passes the
filter.
(gdb-registers-mode-map): New keybinding for toggling the filter.
(gdb-registers-header): New buttons on the header line for the
filter (bug#39179).
* src/coding.c (string_ascii_p): Make it non-static.
* src/fileio.c (Fdirectory_append): Fix check for whether we need
to convert to multibyte.
* src/fns.c (string_ascii_p): Remove copy.
* src/lisp.h: Declare string_ascii_p.
* doc/lispref/files.texi (Directory Names): Document it.
* lisp/emacs-lisp/shortdoc.el (file-name): Add new example.
* src/fileio.c (Fdirectory_append): Change the function to take an
arbitrary number of components.
* doc/misc/smtpmail.texi (Queued delivery): Document it (bug#49709).
* lisp/gnus/message.el (message-multi-smtp-send-mail): Store
variables.
* lisp/mail/smtpmail.el (smtpmail-queue-mail): Mention it.
(smtpmail-store-queue-variables): New variable.
(smtpmail-send-it): Store SMTP variables if requested.
(smtpmail-send-queued-mail): Restore variables.
* lisp/progmodes/compile.el (compilation-error-properties):
When the end-column parameter of a compilation message rule
(in compilation-error-regexp-alist[-alist]) is a function, treat its
return value as if it were matched by the regexp, which is how it is
documented to work, and how all other parameters work.
Wrong number of arguments in inlining function calls (to `defsubst` or
explicitly using `inline`) did not result in warnings, or in very
cryptic ones.
* lisp/emacs-lisp/byte-opt.el (byte-compile-inline-expand): Add calls
to `byte-compile--check-arity-bytecode`.
* lisp/emacs-lisp/bytecomp.el (byte-compile-emit-callargs-warn)
(byte-compile--check-arity-bytecode): New functions.
(byte-compile-callargs-warn): Use factored-out function.
* test/lisp/emacs-lisp/bytecomp-resources/warn-callargs-defsubst.el:
* test/lisp/emacs-lisp/bytecomp-tests.el ("warn-callargs-defsubst.el"):
New test case.
* lisp/erc/erc-button.el (erc-button-add-buttons-1): Remove text
properties from strings stored in `erc-data' and passed to
`erc-callback'
(both text properties themselves) (bug#49704). This reduces
memory usage in erc buffers (which are long-lived and can become
very large).
* lisp/textmodes/fill.el (current-fill-column): Make nil value of
'fill-column' obsolete. (Bug#22847)
(current-fill-column--has-warned): New variable to track warning.
* lisp/simple.el (do-auto-fill): Remove handling of nil return value
from 'current-fill-column'.
* etc/NEWS: Announce obsoletion of this usage.
* lisp/time.el (display-time-string-forms):
* lisp/battery.el (battery-mode-line-format): Add a space to the
end (bug#30056).
* lisp/bindings.el (mode-line-misc-info): Remove space from end.
This will make the default format have one space before the
line-of-dashes (instead of two) on terminals.
* admin/merge-gnulib (GNULIB_MODULES): Add file-has-acl.
* lib/file-has-acl.c: New file, copied from Gnulib.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib-src/emacsclient.c: Include acl.h, for file_has_acl.
(O_PATH): Default to O_SEARCH, which is good enough here.
(union local_sockaddr): New type.
(socket_status): Remove, replacing with ...
(connect_socket): New function. All callers changed.
This function checks for ownership and permissions issues with the
parent directory of the socket file, instead of checking the
owner of the socket (which does not help security).
(socknamesize): Move to file scope.
(local_sockname): New arg S. No need to pass socknamesize.
UID arg is now uid_t. All callers changed. Get file descriptor
of parent directory of socket, to foil some symlink attacks.
Do not follow symlinks to that directory.
(set_local_socket): Create the socket here instead of on
each attempt to connect it. Fall back from XDG_RUNTIME_DIR
to /tmp only if the former fails due to ENOENT. Adjust
permission-failure diagnostic to match changed behavior.
This addresses Bug#33847, which complained about emacsclient in a
safer XDG environment not connecting to an Emacs server running in
a less-safe enviroment outside XDG. The patch fixes a
longstanding issue with emacsclient permission checking.
It’s ineffective to look at the permission of the socket file
itself; on some platforms, these permissions are ignored anyway.
What matters are the permissions on the parent directory of the
socket file, as these are what make symlink attacks possible.
Change the permissions check accordingly, and also refuse to
follow symlinks to that parent directory. These changes make it
OK for emacsclient to fall back from XDG_RUNTIME_DIR to the
traditionally less-safe /tmp/emacsNNNN directories, since /tmp is
universally sticky nowadays.
* src/xdisp.c (get_line_prefix_it_property): New function.
(handle_line_prefix): Call 'get_line_prefix_it_property' instead
of 'get_it_property', to examine also the property of the buffer
text underlying the display or overlay string. (Bug#49695)
