Previously, the success of `getline` was tested by checking if the
buffer it allocates is nonempty and has a nonzero first byte. As
`getline` does not explicitly zero out its memory buffer, this may
fail (e.g., with AddressSanitizer). Instead, we check that at least one
character was returned on standard output.
Also, trailing newlines (if present) are now removed.
If output->configured is true, then the output has been modeset correctly and
we don't need to try again. If output->enabled is true, then we are in the
process of configuring the output and we shouldn't do anything.
Designing the output configuration sequence without invalid state is tricky.
We have one function, apply_output_config, that takes an output and (besides
other things) performs a modeset and inserts the output in the output layout.
The modeset can fail, in which case we don't want the output to be enabled.
We also have an output_enable function, which calls output_apply_config and
also configures the output's workspace and inserts it in the root container.
Now, we have two choices.
Either we configure the output before it's been inserted in the root container
and then, if the modeset was successful, we insert it and create the workspace.
The main issue with this approach is that configuring the output triggers a
handful of signals, namely wlr_output.mode and wlr_output_layout.change. In
those event handlers, we need to make sure to ignore these outputs in the
process of being configured.
Either we first insert the output, create the workspace and then try to
configure it. It means we need to undo everything if the modeset fails. The
main issue with this solution is that it enables and disables the output very
quickly, creates a workspace and immediately destroys it, and maybe moves
views back and forth (see output_evacuate).
I've tried to make it so an output isn't enabled then immediately disabled. We
already have code for ignoring outputs when the output is being destructed.

This happens if you plug in more outputs than supported by your GPU.
This patch makes it so outputs without CRTCs appear as disabled. As soon as
they get a CRTC (signalled via the mode event), we can enable them.
This modifies `bar_cmd_tray_bindsym` to use `get_mouse_bindsym` for
parsing mouse buttons. This also introduces `bar_cmd_tray_bindcode`,
which will use `get_mouse_bindcode` for parsing mouse buttons. Like with
sway bindings, the two commands are encapsulated in a single file to
maximize shared code.
This also modifies tray bindings to work off of events codes rather than
x11 buttons, which allows for any mouse buttons to be used.
For `get_bar_config`, `event_code` has been added to the `tray_bindings`
section and will include to event code for the button. If the event code
can be mapped to a x11 button, `input_code` will still be the x11 button
number. Otherwise, `input_code` will be `0`.
In `sway_terminate`, `ipc_event_shutdown` was being sent regardless
which mode sway was running in. When running as an ipc client,
`sway_terminate` should just exit
Clear the focus when we hide the cursor and show it again during the unhide
action. The unhide function will rebase the cursor after the unhide.
Tested by looking at the WAYLAND_DEBUG=1 output of termite.
Also call cursor_handle_activity before sending pointer events to send the enter
events to the surface if the cursor was hidden before.
Fixes#3431
This fixes the handling of hidden scratchpad containers for some
commands. For the most part, this just prevents running the commands on
hidden scratchpad containers, but there are some commands that have some
special handling for them.
For example, create layout V[view view view] and resize the leftmost
view using mod+rightclick. Previously, the edge between view 2 and 3
would be adjusted as well. Now this edge will remain constant, which
matches the behaviour of i3.
To do this operation correctly, the resize tiling seatop now keeps track
of two containers, as the container that resizes horizontally will be a
different container to the one which resizes vertically (one will be an
ancestor). The tiling resize seatop now figures out these containers
during the start of the operation and keeps references to them in the
event. A new function container_find_resize_parent has been introduced
to do this. This function is also used by the resize command.
During cursor motion, the seatop logic is similar to before, but now has
to choose the correct container to resize.
In resize.c, container_resize_tiled and resize_tiled have been merged
into one. One of them originally did nothing except pass the values
through to the other.
container_resize_tiled now takes a simplified approach where it just
finds the immediate siblings on either side and resizes them without
worrying about the others. The parellel_coord and parallel_size
functions are no longer needed and have been removed.
When resetting the keyboard during reload, disarm the key repeat on all
keyboards since the bindings (and possibly keyboard) will be freed before
the key repeat can go off.
