The check didn't include && ws_num < 100 so l would always be 1 or 2
Instead of fixing logic it's simpler to just call snprintf twice to get
length and use that.
Also change malloc failure check to sway_assert because both callers of
this function do not do null check and would segfault...
Found through static analysis.
When you spawn a process with the exec command, sway now notes the
workspace you had focused and the pid of the child process, then assigns
that workspace to the child when its window appears.
Some of this is carried over from sway 0.15, but with some major
refactoring and centralization of state.
Rather than allocate a structure and expect callers to free it, take a
pointer to an existing struct as an argument.
This function is no longer called anywhere though.
Emitting the close event needs to happen before
container_output_destroy, because container_output_destroy sets the
sway_output to NULL and sway_output is used in IPC.
We were freeing the sway_output immediately upon disconnect which left
a dangling pointer in the output's container. It then tried to use the
pointer when the container is freed.
We don't need to store the sway_output in an output's container which is
destroying, so the fix is to set the pointer to NULL and remove the use
in container_free.
Also added an arrange when the output is disconnected for good measure.
It happened when a view is a grandchild or deeper of the workspace, is
fullscreen, and unmaps. The workspace would not be included in the
transaction and its pointer to the fullscreen view was left dangling.
container_destroy was calling container_reap_empty, which calls
container_destroy and so on. Eventually the original container_destroy
would return a NULL pointer to the caller which caused a crash.
This also fixes an arrange on the wrong container when moving views in
and out of stacks.
* The arrange_foo functions are now replaced with arrange_and_commit, or
with manually created transactions and arrange_windows x2.
* The arrange functions are now only called from the highest level
functions rather than from both high level and low level functions.
* Due to the previous point, view_set_fullscreen_raw and
view_set_fullscreen are both merged into one function again.
* Floating and fullscreen are now working with transactions.
`_container_destroy` emits a destroy event, and any listener for this
event should have access to the full container, not a half destroyed
one.
`_container_destroy` also destroys the swayc, so we have to grab a
reference to the sway_workspace so we can free it afterwards.
This also fixes a memory leak where the floating container wasn't freed.
Fixes#2092.
* Attach sticky containers to new workspaces when switching
* Fire the close event *before* we start destroying the workspace to
prevent a crash
Because the sticky container now follows the visible workspace, this
simplifies the rendering and container_at logic.
When moving focus left or right to an adjacent output, only select the
first or last child in the new workspace if the workspace's layout is
horizontalish. If it's a verticalish layout, use the last focused
container.
* Add and use lenient_strcat and lenient_strncat functions
* Rename `concatenate_child_titles` function as that's no longer what it
does
* Rename `container_notify_child_title_changed` because we only need to
notify that the tree structure has changed, not titles
* Don't notify parents when a child changes its title
* Update ancestor titles when changing a container's layout
* Eg. create nested tabs and change the inner container to stacking
* No need to store tree presentation in both container->name and
formatted_title
