Before this commit, there would be cases where focus changes from one
window to another, the new window activates text_input, then the old
window sends a deactivate request, making text_input unfocused
completely.
There is no need to check for transactions at the end of every user
input, as the vast majority of input will not issue transactions. This
implementation can also hide where changes are made without an
appropriate transaction commit, as a future unrelated input would issue
the commit instead.
Instead, commit transactions in places where changes are made or are
likely to be made.
xdg_shell and xwayland handled geometry changes differently despite
needing mostly identical behavior. The xwayland implementation has been
changed to match that of xdg_shell.
The size of a tiled container cannot change in response to new buffer
sizes, so there is no need to commit a new transaction. Instead, simply
recenter the view with the new geometry, leaving the full transaction
flow for floating containers.
We need to use surface_x and surface_y when rendering and damaging saved
buffers as these compensate for views that have been centered due to
being smaller than their container.
Add them to the surface positions on the saved buffer so we have the
values from the time the buffer was saved.
Sway records pid, workspace, and output for every new process. However, if the
output gets disabled and the workspace disappears, the workspace is still
re-created on the disabled output. This commit adds a check for the enabled
flag, so that NULL will be passed to workspace_create() in this case.
wlr_output_configuration_head_v1_create normally fills out the head
"enabled" field to match the wlr_output state. We overwrite this to also
set the head as enabled if it is only turned off with DPMS.
However, in some cases we may not have a mode for this display, in which
case setting it as enabled will lead to a segfault later on. Therefore,
enabled conditional on the presence of a mode.
For certain applications (e.g. JetBrains) the parent window controls
input. We need to adhere to the ICCCM input focus specification to
properly handle these cases.

Instead of calling wlr_xdg_surface_for_each_popup and then
wlr_surface_for_each_surface, use the new for_each_popup_surface helper
introduced in [1] that does it in one go.

workspace_squash is container_flatten in the reverse
direction. Instead of eliminating redundant splits that are
parents of the target container, it eliminates pairs of
redundant H/V splits that are children of the workspace.
Splits are redundant if a con and its grandchild have the
same layout, and the immediate child has the opposite split.
For example, layouts are transformed like:
H[V[H[app1 app2]] app3] -> H[app1 app2 app3]
i3 uses this operation to simplify the tree after moving
heavily nested containers to a higher level in the tree via
an orthogonal move.
This changes the move command to better match i3
behavior after the layout changes.
workspace_rejigger handled the case where containers would
escape their workspace in an orthogonal move by changing
the layout to accomodate them, but this case is now handled
within the loop.
In i3, the workspace_layout command does not affect the
workspace layout. Instead, new workspace level containers
are wrapped in the desired layout and the workspace layout
always defaults to the output orientation.
Some comparisons of current Sway versus i3 behavior:
1) T[T[T[app]]] + move left
* Sway: T[app]
* i3: T[T[app]]
2) H[V[H[V[app]]]] + move left
* Sway: H[app]
* i3: H[V[app]]
After this commit, Sway behavior matches i3. The intermediate states
are now:
T[T[T[app]]] -> T[T[app T[]]] -> T[T[app]]
H[V[H[V[app]]]] -> H[V[app H[V[]]]] -> H[V[app]]
In i3 the layout command on a workspace affects the workspace layout
only on empty workspaces. Otherwise children are placed in a new
container with the desired layout to preserve the workspace layout.
Instead of letting wlroots print messages to stdout, route debugging
messages into Sway's logging functions. This allows a more consistent
output (e.g. if Sway or wlroots changes its output style, they don't get
out-of-sync).
I also added a [wlr] prefix to wlroots messages, not yet sure it's a
good thing.
For each following combinations of criteria & command below, the command would
crash sway without the fix.
It's particular about the __focused__ criteria, where the view matches part of
the criteria but not the focused app, leading to a failure when calling
`strcmp` with NULL.
"xterm" is a non-wayland app (X11) and "kitty" is. Both are terminals.
# "class" is specific to X11
# The view is X11 (xterm) leading to the criteria checking for the
# focused app's class, leading to a crash
for_window [class="__focused__"] floating enable
exec kitty -e xterm
# Similarly, crash as the focused app (xterm) has no app_id when the view has one
for_window [app_id="__focused__"] floating enable
exec xterm -e kitty
# If the view has a title but not the focused app: NULL title will crash criteria checking
for_window [title="__focused__"] floating enable
exec xterm -title "" -e xterm
Currently, when sway sends a configure with some geometry and the
client responds with a different geometry in a commit that acks that
configure, sway ignores the new size. Sway applies the surface
geometry it had requested to the container, not what was actually
committed, in the following transaction.
This change allows any client commit to change its surface geometry,
even if it is a response to a configure event.
