This bug affected compilation of
(cond ((member '(some list) variable) ...) ...)
While equal is symmetric, member is not; in the latter case the
arguments must be a variable and a constant list, in that order.
Reported by Ikumi Keita.
* lisp/emacs-lisp/bytecomp.el (byte-compile--cond-switch-prefix):
Don't treat equality and member predicates in the same way; only
the former are symmetric in their arguments.
* test/lisp/emacs-lisp/bytecomp-tests.el
(byte-opt-testsuite-arith-data): Add test cases.
* lisp/startup.el (normal-top-level): Also delete PWD if
file-attributes fails for either $PWD or default-directory,
instead of failing out of the top level.
This fixes a regression from Emacs 26 (Bug#42903).
Some WMs (e.g. mutter in Gnome Shell) don't unmap iconized windows,
thus we won't get a MapNotify when deconifying them.
Check if we are deconifying a window elsewhere (Bug#42655).
- src/xterm.c (handle_one_xevent):
Check for window deconify when receiving a FocusIn signal.
* etc/NEWS: Note that Emacs needs to be built with systemd support
systemd is used to stop/start Emacs (bug#42242). Change suggested by
Bhavin Gandhi <bhavin7392@gmail.com>
* src/xfaces.c (merge_face_ref): Handle correctly faces that
inherit from another, and in addition specify :extend.
(Bug#42552)
(cherry picked from commit 39c90f8dfa)
* src/xdisp.c (face_at_pos): Pass ATTR_FILTER to
face_for_overlay_string.
* src/xfaces.c (face_for_overlay_string): Accept an additional
argument ATTR_INDEX and pass it to merge_face_ref for merging the
face at POS. This ensures a face from buffer text will not be
merged unless it specifies the :extend attribute. (Bug#42552)
* src/dispextern.h (face_for_overlay_string): Adjust prototype.
(cherry picked from commit 35564bea4d)
* lisp/so-long.el (so-long-remember-all, so-long-disable-minor-modes)
(so-long-override-variables): Store and use the `so-long-minor-modes'
and `so-long-variable-overrides' values seen by the original major
mode, so that buffer-local changes made in the major mode hook will be
respected.
Add documentation of this and other major mode hook usage.
* lisp/so-long.el (so-long-detected-long-line-p): Ensure that
`comment-start-skip' and `comment-end-skip' are both set if
`comment-use-syntax' is nil, as `comment-forward' requires them
to be bound in this scenario.
As this `require' is not at the top-level (it is only conditionally
evaluated, when loading the library over the top of an earlier
version), we need `eval-and-compile' to ensure that both macros and
functions from advice.el are accounted for.
Reverting certain changes from commits b0f20651e3 and d1a791f8ed.
Please refer to the comments on spelling at the end of the library.
M-x ispell-buffer should find no misspellings in the documentation.
See also test/lisp/so-long-tests/spelling-tests.el
(The current spelling will persist while so-long.el is maintained in
its own Savannah repository, to avoid unnecessary conflicts between
the two versions. If in the future it is maintained solely in the
Emacs repository, changing the spelling would become an option.)
Note that "mitigations" (plural) is intentional -- this library
identifies a collection of different performance mitigations,
multiple of which will typically be in effect together.
Emacs segfaults at the X11 initialization if XIM is set
and xim_styles is NULL. This patch avoids the crash.
* src/xfns.c: Check also if FRAME_X_XIM_STYLES(f) is NULL.
(Bug#42676) (Bug#42673) (Bug#42677)
Copyright-paperwork-exempt: yes
We can't just use a hash lookup because a global and a local reference
might refer to the same Lisp object.
* src/emacs-module.c (module_free_global_ref): More precise check for
global liveness.
(cherry picked from commit 9f01ce6327)
We can't simply look up the Lisp object in the global reference table
because an invalid local and a valid global reference might refer to
the same object. Instead, we have to test the address of the global
reference against the stored references.
* src/emacs-module.c (module_global_reference_p): New helper function.
(value_to_lisp): Use it.
(cherry picked from commit 6355a3ec62)
Instead of storing the global values in a global 'emacs_value_storage'
object, store them as hash values alongside the reference counts.
That way the garbage collector takes care of cleaning them up.
* src/emacs-module.c (global_storage): Remove.
(struct module_global_reference): New pseudovector type.
(XMODULE_GLOBAL_REFERENCE): New helper function.
(module_make_global_ref, module_free_global_ref): Use
'module_global_reference' struct for global reference values.
(value_to_lisp, module_handle_nonlocal_exit): Adapt to deletion of
'global_storage'.
(cherry picked from commit 5c5eb97908)
