| | | | | | | | * src/emacs.c (load_pdump): Don't overwrite the leading directories of the Emacs executable just because the pdumper file was not found in the expected directory relative to the binary. This is needed to support builds with a separate --bindir configure-time option and native-compilation. (Bug#55741)

* do_switch_frame: before leaving mini-window, check other (mru) window is liveAlan Mackenzie2022-05-281-1/+7
| | | | | | | | | | | | This fixes bug#55684. There, with a minibuffer-only frame at start up, Emacs tried to switch to this frame, whose selected window was the mini-window. There is no other active window in this frame, so the attempt to swith to another window failed. * src/frame.c (do_switch_frame): On switching to a frame whose selected window is as above, before selecting the most recently used window, check this ostensible window is an actual live window. Otherwise leave the mini-window selected.
* Restore the Fselect_window call in gui_consider_frame_title.Alan Mackenzie2022-05-204-10/+11
| | | | | | | | | | | | | | | | | | | | | This fixes bug #55412. The call to Fselect_window was removed on 2021-03-21 in the commit "Prevent open minibuffers getting lost when their frame gets deleted". This call is actually needed to determine current elements of the pertinent window and frame when these are used in the frame title. * src/frame.c (do_switch_frame): When the selected window in the target frame is the mini-window, switch away from this window unless there is a valid minibuffer there. * src/frame.h (struct frame): Add an incidental comment about the element selected_window. * src/minibuf.c (move_minibuffers_onto_frame): No longer set the selected window of the source frame. This action is now performed later, on returning to that frame, in do_switch_frame when needed (see above). * src/xdisp.c (gui_consider_frame_title): Replace the Fselect_window call and associated ancillary settings.

* Revert "Don’t assume openat"Eli Zaretskii2022-04-171-18/+11
| | | | | | | | | | This reverts commit 3cccf0a9107d585173e527550bbc45253624ca2e. This is a change with far-reaching effects on MS-Windows at the least, where file-related APIs are shadowed to support transparent support for UTF-8 encoded file names. Making such changes on a stable branch for the benefit of a proprietary platform with a 13-year old OS is a tail wagging the dog. Please don't do that without discussing first.
* Don’t assume openatPaul Eggert2022-04-171-11/+18
| | | | | | | | | | | | | | Use openat only on platforms with O_PATH. This ports to OS X 10.9 and earlier. Problem reported by Keith David Bershatsky in: https://lists.gnu.org/r/emacs-devel/2022-04/msg00805.html * lib-src/emacsclient.c (local_sockname): Use open, not openat. * src/sysdep.c (sys_openat): New static function, which uses openat only if O_PATH is defined. (emacs_openat): Use it instead of openat. (emacs_openat_noquit): Remove. (emacs_open_noquit): Reimplement as per the old emacs_openat_noquit, but use plain 'open'.
* Fix GC bug in filelock.cPaul Eggert2022-04-171-25/+23
| | | | | | | | | | | | | | Fix a bug where if GC occurred at the wrong moment when locking a file, the lock file’s name was trashed so file locking did not work. This bug was introduced in Emacs 28.1. The bug sometimes caused filelock-tests-detect-external-change test failures on Fedora 35 x86-64 in an en_US.utf8 locale. * src/filelock.c (lock_file_1, current_lock_owner, lock_if_free) (lock_file, unlock_file, Ffile_locked_p): Use Lisp_Object, not char *, for string, so that GC doesn’t trash string contents. (make_lock_file_name): Return the encoded name, not the original. All callers changed.

* Fix builds on older versions of macOSMattias Engdegård2022-04-161-0/+24
| | | | | | | | | | This adds back macOS-specific code replaced earlier (bug#48548), specifically to fix build errors on macOS 10.7.5. See discussion at https://lists.gnu.org/archive/html/emacs-devel/2022-04/msg00779.html . * src/sysdep.c (HAVE_RUSAGE_INFO_CURRENT, HAVE_PROC_PIDINFO): New. (system_process_attributes): Use alternative code or exclude features when building on older macOS versions.
* Fix cursor motion under truncate-lines with Flymake fringe indicatorEli Zaretskii2022-04-151-1/+4
| | | | | | * src/indent.c (Fvertical_motion): Don't consider fringe bitmaps as "images" for the purpose of vertical-motion logic dealing with overshooting buffer positions. (Bug#54946)
