The problem here is that con_fullscreen_permits_focusing() does not
check if there is a blocking fullscreen container in the workspace that
the container to be focused belongs. This makes it possible to focus a
container behind a fullscreen window if it's in an unfocused workspace.
This commit introduces a change in the 'focus' command behaviour. When
focusing a container blocked by a fullscreen container, either CF_OUTPUT
or CF_GLOBAL, the blocking container loses its fullscreen mode and the
target container is focused like normal.
This should not affect directional focus commands: left, right, up,
down, parent, child.
Fixes issue #1819.
The bug triggers when _workspace_show calls tree_close_internal and
old == old_focus. Ie, when the old workspace was empty and needs to be
closed but then is accessed as output_push_sticky_windows's argument:
Breakpoint 1, output_push_sticky_windows (to_focus=0x55555589c8a0) at ../../i3/src/output.c:102
102 con_move_to_workspace(current, visible_ws, true, false, current != to_focus->parent);
(gdb) print con_exists(to_focus)
$1 = false
The access violation can also be prevented by checking if
con_exists(old_focus) but it shouldn't be necessary: the old_focus
container can only be killed when it is an empty workspace.
With --enable-sanitizers this causes i3 to exit but with
--disable-sanitizers the access violation doesn't reliably cause a crash
and the con_move_to_workspace call continues with:
(gdb) print current != to_focus->parent
$2 = 1
Since current->type is CT_FLOATING_CON and to_focus->type is
CT_WORKSPACE, in this specific case ignore_focus would always be true.
So, in this case, passing NULL instead of old_focus to
output_push_sticky_windows doesn't change the behaviour of i3.
Fixes#3075.
Prevents a false-positive error eg with config file:
set $mod Mod4
bindsym $mod+h split h
bindsym $mod+v split v
ERROR: CONFIG: Expected one of these tokens: <end>, '#', 'set ', ...
ERROR: CONFIG: Line 8: status_command i3status
ERROR: CONFIG: Line 9: }
ERROR: CONFIG: Line 10: <BE><BE><BE><BE><BE><BE>
With this change i3 will correctly switch to the focused workspace.
This fixes bug with moving floating windows with 'move <direction>' or by dragging like _NET_CURRENT_DESKTOP not getting updated or 'workspace back_and_forth' not working.
Fixes#2921.
i3bar's handle_button is modified to also handle XCB_BUTTON_RELEASE
events. During these button release events, only custom commands are
checked to avoid sending multiple workspace ipc messages.
The way this patch is implemented will allow to assign a custom command
for both the press and release of the same button:
bar {
...
bindsym buttonX exec command1
bindsym --release buttonX exec command2
}
Fixes#3068.
Issue #3049 describes a case where terminating i3 by means of SIGTERM
causes it to leak the runtime directory and all its contents. There are
multiple issues at play: first, any cleanup handlers registered via
atexit are never invoked when a signal terminates the program (see
atexit(3)). Hence, the log SHM log cleanup performed in i3_exit is not
invoked in that case. Second, compared to the shutdown path for the
'exit' command, we do not unlink the UNIX domain socket we create,
causing it to be leaked as well. Third, a handler for SIGTERM is not
registered at all despite handle_signal claiming to be the handler for
all 'Term' signals.
This change addresses all three problems and results in a graceful exit
including cleanup to happen when we receive a signal with the default
action 'Term'. It addresses issue #3049.
In i3bar/src/config.c we compare string lengths agains magic numbers.
This change replaces those numbers with the lengths of the strings they
represent.
The userguide still mentions an old 'goto' command which no longer
exists and will be ignored silently (when used in the i3 config) or
causes an error to be reported (when invoked from the command line).
This change updates the userguide to correct this problem. In addition
to that it also updates the i3-input command shown to no longer use the
deprecated -p flag but -F instead.
