This fixes two causes of segfaulting when an output is destroyed.
The first occurred when an output was never enabled. The issue was that
the destroy signal was never initialized so when it was emitted, sway
segfaulted. This was fixed by moving the initialization into
`output_create` since all outputs, regardless of whether they have ever
been enabled, will be destroyed at some point.
The second occurred when the cursor was on an output that was being
destroyed. The sway output would have already been removed, but if there
are other outputs, a cursor rebase would still occur. Since the
wlr_output still existed and the sway output was destroyed, the cursor
could be over nothing, resulting in a segfault when trying to get the
sway output, which was destroyed.
This allows tabbed and stacked containers to be scrolled through when
the cursor is over the border of the title bar. The borders around the
other three edges of the contents should not be affected by this change.
The following helper functions have been added to aid with parsing mouse
buttons from a string:
1. `get_mouse_bindsym`: attempts to parse the string as an x11 button
(button[1-9]) or as an event name (ex BTN_LEFT or BTN_SIDE)
2. `get_mouse_bindcode`: attempts to parse the string as an event code
and validates that the event code is a button (starts with `BTN_`).
3. `get_mouse_button`: this is a conveniency function for callers that
do not care whether a bindsym or bindcode are used and attempts to parse
the string as a bindsym and then bindcode.
None of these functions are used in this commit. The sole purpose of
this commit is to make the larger set more granular and easier to
review/manipulate. There will be a series of commits following this one
that will modify any command which uses a mouse button to use these
helpers.

Since the keyboard can be destroyed by executing a binding (reloading
with a different seat attachment config), update the repeat timer before
executing the binding.
Unhide the cursor if container warping is enabled.
Also set the image_surface to NULL during view_unmap, otherwise the cursor will
try to access the surface which is currently being unmapped.
Implements `tiling_drag_threshold <threshold>` to prevent accidental
dragging of tiling containers. If a container (and all of its
descendants) are unfocused and the tile bar is pressed, a threshold
will be used before actually starting the drag. Once the threshold has
been exceeded, the cursor will change to the grab icon and the operation
will switch from `OP_MOVE_TILING_THRESHOLD` to `OP_MOVE_TILING`.
The implicit fallback seat config needs to be applied (if created).
Otherwise, the input devices will still be removed from the implicit
default seat on reload when there is any seat config.
This fixes an issue where on reload, all input devices that were added
via an implicit fallback to the default seat would be removed from the
default seat and applications would crash due to the seat having no
capabilities.
On reload, there is a query for a seat config with the fallback setting
set (it can either be true or false). If no such seat config exists, the
default seat is created (if needed) and has the implicit fallback true
applied to its seat config. This is the same procedure that occurs when
a new input is detected.
This makes seat configs work like output and input configs do. This also
adds support for wildcard seat configs. A seat config is still created
in the main seat command handler, but instead of creating a new one in
the subcommands and destroying the main seat command's instance, the
seat subcommands modify the main one. The seat config is then stored,
where it is merged appropriately. The seat config returned from
`store_seat_config` is then applied. When attempting to apply a wildcard
seat config, a seat specific config is queried for and if found, that is
used. Otherwise, the wildcard config is applied directly.
Additionally, instead of adding input devices to the default seat
directly when there is no seat configs, a seat config for the default
seat is created with only fallback set to true, which is more explicit.
It also fixes an issue where running a seat command at runtime (with no
seat config in the sway config), would result in all input devices being
removed from the default seat and leaving sway in an unusable state.
Also, instead of checking for any seat config, the search is for a seat
config with a fallback option seat. This makes it so if there are only
seat configs with fallback set to -1, the default seat is still created
since there is no explicit notion on what to do regarding fallbacks.
However, if there is even a single fallback 0, then the default seat is
not used as a fallback. This will be needed for seat subcommands like
hide_cursor where the user may only want to set that property without
effecting anything else.
This fixes a bug in `dispatch_cursor_button` where if there was an
operation occurring, the button would not be removed from the state on
release. This resulted in the button appearing to be permanently pressed
and caused mouse bindings to not match correctly.
This modifies the way mouse bindings are parsed. Instead of adding to
BTN_LEFT, which results in button numbers that may not be expected,
buttons will be parsed in one of the following ways:
1. `button[1-9]` will now map to their x11 equivalents. This is already
the case for bar bindings. This adds support for binding to axis events,
which was not possible in the previous approach.
2. Anything that starts with `BTN_` will be parsed as an event code name
using `libevdev_event_code_from_name`. This allows for any button to be
mapped to instead of limiting usage to the ones near BTN_LEFT. This also
adds a dependency on libevdev, but since libevdev is already a dependency
of libinput, this should be fine. If needed, this option can have dependency
guards added.
Binding changes:
- button1: BTN_LEFT -> BTN_LEFT
- button2: BTN_RIGHT -> BTN_MIDDLE
- button3: BTN_MIDDLE -> BTN_RIGHT
- button4: BTN_SIDE -> SWAY_SCROLL_UP
- button5: BTN_EXTRA -> SWAY_SCROLL_DOWN
- button6: BTN_FORWARD -> SWAY_SCROLL_LEFT
- button7: BTN_BACK -> SWAY_SCROLL_RIGHT
- button8: BTN_TASK -> BTN_SIDE
- button9: BTN_JOYSTICK -> BTN_EXTRA
Since the axis events need to be mapped to an event code, this uses the
following mappings to avoid any conflicts:
- SWAY_SCROLL_UP: KEY_MAX + 1
- SWAY_SCROLL_DOWN: KEY_MAX + 2
- SWAY_SCROLL_LEFT: KEY_MAX + 3
- SWAY_SCROLL_RIGHT: KEY_MAX + 4
This combines `output_by_name` and `output_by_identifier` into a single
function called `output_by_name_or_id`. This allows for output
identifiers to be used in all commands, simplifies the logic of the
callers, and is more efficient since worst case is a single pass through
the output list.
Enables titling views to be dragged by the titlebar. This is in addition
to using the modifier and dragging them from anywhere on the container
surface. Floating views already allow this behavior.
My previous attempt was not quite right. Changing the focus stack on a
non-visible workspace should only be blocked if the focus would be set
to the workspace itself
Changing the focus stack when destroying a container's node on a
non-visible workspace (on an non-focused output) incorrectly causes
the non-visible workspace to become visible. If the workspace is empty,
it will not be destroyed since it is now visible. Additionally since
there was no workspace::focus event, swaybar still shows the previous
workspace as focus-inactive. It also makes no sense to change visible
workspaces due to a container on a non-visible workspace being
destroyed.
Since the focus will either be set when switching to the non-visible
workspace or the workspace will be destroyed due to being empty, there
is no need to change the focus stack when destroying a container on a
non-visible workspace.
This renames/moves the following properties:
* sway_view.{x,y,width,height} ->
sway_container.content_{x,y,width,height}
* This is required to support placeholder containers as they don't
have a view.
* sway_container_state.view_{x,y,width,height} ->
sway_container_state.content_{x,y,width,height}
* To remain consistent with the above.
* sway_container_state.con_{x,y,width,height} ->
sway_container_state.{x,y,width,height}
* The con prefix was there to give it contrast from the view
properties, and is no longer useful.
The function container_set_geometry_from_floating_view has also been
renamed to container_set_geometry_from_content.
input_manager_set_focus is used to set the focus after mapping the view in
view_map. This needs to consider to warp the cursor as well, since for
WARP_CONTAINER, the cursor should warp to the newly created view.
The code being changed is responsible for updating the focus stack when
a container is destroyed in a different part of the tree to where the
real focus is. It's attempting to set focus_inactive to a sibling (or
parent if no siblings) of the container that is being destroyed, then
put our real focus back on the end of the focus stack.
The problem occurs when the container being destroyed is in a different
workspace. For example:
* Have a focused view on workspace 1
* Have workspace 2 not visible with a single view that is unmapping
* The first call to seat_set_raw_focus sets focus to workspace 2 because
it's the parent
* Prior to this patch, the second call to seat_set_raw_focus would set
focus to the view on workspace 1
* Later, when using output_get_active_workspace, this function would
return workspace 2 because it's the first workspace it finds in the
focus stack.
To fix this, workspace 1 must be placed on the focus stack between
workspace 2 and the focused view. That's what this patch does.
Lastly, it also uses seat_get_focus_inactive to choose the focus. This
fixes a crash when a view unmaps while a non-container is focused (eg.
swaylock), because focus is NULL.
This approaches cursor rebasing from a different angle. Rather than
littering the codebase with cursor_rebase calls and using transaction
callbacks, this just runs cursor_rebase after applying every transaction
- but only if there's outputs connected, because otherwise it causes a
crash during shutdown.
There is one known case where we still need to call cursor_rebase
directly, and that's when running `seat seat0 cursor move ...`. This
command doesn't set anything as dirty so no transaction occurs.
For example, create layout H[view T[view view view]], focus the view in
the hsplit and scroll the mouse wheel over the tab title bars. Prior to
this patch, focus would be given to a descendant of the tabbed
container. This patch keeps the focus on the hsplit view.
This also renames some of the variables used in this part of the code to
make it be easier to follow.
The cursor's image would be removed or set when the seat's capabilities
were updated, but there was nothing to prevent the image from being set
at other times.
* When using multiple seats, each seat has its own prev_workspace_name
for the purpose of workspace back_and_forth.
* Removes prev_workspace_name global variable.
* Removes unused next_name_map function in tree/workspace.c.
* Fixes memory leak in seat_destroy (seat was not freed).
