A race condition is possible. For example, if we first receive a
XCB_MOTION_NOTIFY event and then, while drain_drag_events is still
running, a XCB_BUTTON_RELEASE event the first event is never handled
because we return.
This fixes the flakiness of the tests in #3085.
Right now tree_render() is called twice on DRAG_REVERT since
floating_reposition calls it.
Also, on DRAG_REVERT the scratchpad state shouldn't change since the
user canceled the action.
This change only affects clients that are subscribed to events, which
should be the main cause of our problems.
In the common case (no buffered data) the behaviour doesn't change at
all: the message is sent directly, no ev_io / ev_timeout callback is
enabled. Once a write to a client's socket is not completed fully
(returns with EAGAIN error), we put the message in the tail of a queue
and init an ev_io callback and a corresponding timer. If the timer is
triggered first, the socket is closed and the client connection is
removed. If the socket becomes writeable before the timeout we either
reset the timer if we couldn't push all the buffered data or completely
remove it if everything was pushed.
We could also replace ipc_send_message() for all client connections in
i3, not just those subscribed to events.
Furthermore, we could limit the amount of messages stored and increase
the timeout (or use multiple timeouts): eg it's ok if a client is not
reading for 10 seconds and we are only holding 5KB of messages for them
but it is not ok if they are inactive for 5 seconds and we have 30MB of
messages held.
Closes#2999Closes#2539
This commit makes multiple changes in tree_close_internal. I didn't
split them because they are not completely independent.
- Remove force_set_focus parameter
This parameter was always set to `false` throughout the code base except
for one case where it was set to `(con == focused)`, when killing a
floating con's parent (the one with type CT_FLOATING_CON). But this case
is not needed anymore since the special handling of CT_FLOATING_CONs in
con_next_focused was removed in #2941.
- Assume that con_next_focused does not returned a container of type
CT_DOCKAREA. This is reasonable since con_next_focused uses the
focus_head stack and has special handling of CT_DOCKAREA containers.
- Remove is_mapped
This variable was only used in the if block towards the end of
tree_close_internal. Ignoring the, now removed, dockarea code and the
use of force_set_focus this block performed only one useful action:
focus the `next` container when `con == focused`. `con == focused` was a
necessary and sufficient condition for the con_activate call:
if `con != focused` we could reach the inner if blocks because of the
other conditions but would never focus another container. If `con ==
focused` then all other conditions would be irrelevant.
- Remove special handling of floating containers
Since the `next` focused container is calculated through the parent for
floating containers, I moved this code to con_next_focused.
Also, because of the removal of force_set_focus, it appears that we can
call con_on_remove_child for floating containers as well.
This was introduced in 252db3b8c (#3245). That commit moved the
con_activate line inside the loop, meaning it wouldn't always be called.
When the mouse moved after a rename with focus_follows_mouse enabled,
check_crossing_screen_boundary (src/handlers.c:111) called
con_descend_focused that used the wrong focus order.
I also change con_activate to con_focus since we don't really want to
raise floating containers there.
Fixes#3325
This prohibits the usage of workspaces assigned to other outputs in
create_workspace_on_output.
Eg, with config:
workspace 1 output fake-0
workspace 2 output fake-0
and 2 screens workspace 2 would be used for the second screen even
though it is assigned to the first one.
Also introduces a test for workspace assignments that includes the case
described above and some tests that don't fail in the next branch.
This also replaces code in create_workspace_on_output() that is
theoretically more efficient but:
1. It isn't a huge difference since it depends on the number of outputs,
that shouldn't be high.
2. get_assigned_output will be modified and used for #555, then its
logic should be followed in create_workspace_on_output() too.
Another note for create_workspace_on_output: if assigned is not NULL the
condition (assigned != output->con) should never be false, ie if there
is an assigned output to this name, it isn't the current one. This
happens because the current callers check for assignments before calling
create_workspace_on_output().
https://www.x.org/releases/current/doc/kbproto/xkbproto.html#Detectable_Autorepeat
Detectable autorepeat should only affect --release bindings. Currently,
when a user keeps a key pressed, we get multiple KeyPress and KeyRelease
events. With this change, we still get multiple KeyPress events, which
means that you can still keep a key pressed to repeatedly execute a
normal binding, but only one KeyRelease event when the key is physically
released.
Unfortunately, this change is not currently testable because detectable
autorepeat doesn't seem to work under Xephyr. AwesomeWM experienced the
same problem:

The current text is confusing. '--no-auto-back-and-forth' doesn't
disable the 'workspace back_and_forth' command, the flag is not even
valid for that command.
X will not allow a window with ParentRelative background to be created
or reparented under a window with mismatching color depth.
Deal with this by destroying the container frame and creating a new one
with the right depth upon swallowing.
Defer destruction of the frame window until after the updated tree has
been rendered to avoid some distracting flickering.
Fixes#3297
