- Improve / add various error messages.
- Replace all `LOG(…); ysuccess(false);` with `yerror(…);`.
- switch_mode: Remove redundant "ERROR:" ELOG string.
- cmd_move_con_to_workspace*: Make sure that we don't try to move an
empty workspace to another workspace. This can be problematic when we
match a workspace using command criteria (eg marks) and the target is a
non-existing workspace. We create the new workspace but since nothing is
moved there, we are left with an empty workspace. See added testcase.
Fixes#3156.
I couldn't reproduce the problem in a "natural" way so I cheated:
1. Start i3 with gdb
2. Set breakpoing on tree_restore
3. Run, open window, i3-msg restart
5. Open the file in *path with a hex editor
6. Edit the "name" field of the window and insert bytes that are not
valid UTF8
7. Continue
After parsing fails, all nodes including croot are incomplete, meaning
they have to be deleted. We can't recover in any reasonable way so we
have to allow non-UTF8 characters to avoid this situation altogether.
Introduces resize_neighboring_cons in resize.c which is also used by
resize_graphical_handler.
Co-authored-by: Andrew Laucius <andrewla@gmail.com>
Authored original code and tests in #3240. I rewrote most of the
resizing code and fixed the failing tests.
These are the changes that clang-format 6.0.1 makes to the codebase that
clang-format-3.8 doesn't change back.
Useful for those that use a more recent version of clang-format in their
local machines.
This commit will also fix the following bugs:
1. click.c: Users could drag global fullscreen floating containers.
2. render.c: Floating containers would get rendered with a global fullscreen container in another
workspace.
The first issue is that there seems to be a typo: fullscreen->window
should have been child->window. The corrected check is redundant since
the while loop checks if the transient_con has a window.
The second issue is that popup_during_fullscreen is never checked even
though the behaviour should be exclusive to the "smart" option.
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 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().
