This fixes the issue of the display freezing on reload with
wlroots#1545.
On master, all output configs are applied on reload. This may cause an
output to have its config applied up to three times, instead of just
once. The three cases are: output name, output identifier, and wildcard.
Not only is this inefficient, but it can cause swaybg to be spawned and
immediately killed.
However, swaybg requires two roundtrips of wl_display (to obtain needed
globals) before it enters its normal event loop. Modesetting will
roundtrip the wl_display. Without modesetting, waitpid for killing
swaybg could block infinitely due to swaybg being blocked by
wl_display_roundtrip.
This only configured an output once. It either uses the wildcard config
or creates an empty wildcard config and applies that. This also fixes a
bug where an output would not be reset when there is no output config to
apply to it.
On the DRM backend, if an output is dpms'd off and a different output is
hotplugged, the CRTC for the output is reclaimed. When modesetting an
output without a CRTC, a CRTC will not be given to an output that is not
desired to be enabled. This splits setting the dpms state in
apply_output_config. If the output should be dpms on, the it is enabled
before attempting to modeset. Otherwise, it is dpms'd off after setting
everything else.
This also adds DPMS_ON to the default output configs.
This fixes a few misc memory leaks reported by asan:
- Items of `config->config_chain` are now freed instead of just the list
itself
- `bar->swaybar_command` is now freed
- The result returned by a seat subcommand is now returned instead of
leaked
This changes the `pointer_constraint` command to be a subcommand of seat
to allow for per-seat settings. The current implementation that is not a
seat subcommand will only operate on the current seat and will segfault
in the config due to `config->handler_context.seat` only being set at
runtime.
This also allows for the wildcard identifier to be used to alter the
pointer constraint settings on all seats and allows for the setting to
be merged with the rest of the seat config.
Modifier handling functions were moved into sway/input/keyboard.c;
opposite_direction for enum wlr_direction into sway/tree/output.c;
and get_parent_pid into sway/tree/root.c .
This commit mostly duplicates the wlr_log functions, although
with a sway_* prefix. (This is very similar to PR #2009.)
However, the logging function no longer needs to be replaceable,
so sway_log_init's second argument is used to set the exit
callback for sway_abort.
wlr_log_init is still invoked in sway/main.c
This commit makes it easier to remove the wlroots dependency for
the helper programs swaymsg, swaybg, swaybar, and swaynag.
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`.
Adds the bar subcommand `status_padding <padding>` which allows setting
the padding used for swaybar. If `status_padding` is set to `0`, blocks
will be able to take up the full height of the bar.
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.
Moves the call to `terminate_swaybg` from inside `apply_output_config` to
`output_disable`. The former was only called when an output was being
disabled. The latter is called when an output is being disabled and when
an output becomes disconnected. Without this, disconnecting an enabled
output would result in a defunct swaybg process.
Default output configs were generated on reload to reset an output to
its default settings. The idea was that anything that was removed from
the config or changed at runtime and not in the config should be reset
on reload. Originally, they were created using the output name. Recently,
they were changed to use the output identifier. It turns out that there
are issues of shadowing with that solution as well. This should fix
those issues.
Instead of generating the default output configs on reload and storing
them in the output config list to merge on top of, they are now only
generated when retrieving the output config for an output during a
reload. This means that the default output configs are never stored
anywhere and just used as a base to merge unaltered user configs on top
of during a reload.
Starting with a blank output config, merges get applied in the following
order:
1. Default output config (only during a reload)
2. Wildcard config (only if neither output name or output identifier
exist)
3. Output name config
4. Output identifier config
When generating default output configs to reset the outputs to their
default settings on reload, the output name was being used.
Additionally when determining the output config to apply, if there was
an output config with the output name, that was being used without
checking for an identifier config. This caused sway to completely ignore
the users specified output config.
To fix this issue, the following changes have been made:
1. Default output configs as created for the identifier now instead of
name. This actually makes more sense anyway since you could hotplug
multiple different outputs to the same port.
2. In get_output_config, which is only used to determine which output
config to apply, output configs for both the name and identifier are
queried. If both are found, a new output config is generated with the
identifier config merged on top of the name config. If just one is found,
a copy of that config is returned. This change also requires that the
result from get_output_config be freed after use to prevent memory
leaks, which required some minor changes to logic in
apply_output_config_to_outputs.
Since wayland does not currently allow swaybar to create global
keybinds, this is handled within sway and sent to the bar using a custom
event, so as not to pollute existing events, called bar_state_update.
Sway sets a default status_command which runs date every second. This
patch removes this behaviour so the user can have a NULL status bar if
desired.
I had to swap swaybar's event_loop_poll and wl_display_flush so that it
would map the initial surface.
This changes it back so the path given to swaybg is enclosed in quotes.
Additionally, the only character that is escaped in the path stored is
double quotes now. This makes it so we don't need to keep an exhaustive
list of characters that need to be escaped.
The end user will still need to escape these characters in their config
or when passed to swaybg.
This commit changes the meaning of sway_container so that it only refers
to layout containers and view containers. Workspaces, outputs and the
root are no longer known as containers. Instead, root, outputs,
workspaces and containers are all a type of node, and containers come in
two types: layout containers and view containers.
In addition to the above, this implements type safe variables. This
means we use specific types such as sway_output and sway_workspace
instead of generic containers or nodes. However, it's worth noting that
in a few places places (eg. seat focus and transactions) referring to
them in a generic way is unavoidable which is why we still use nodes in
some places.
If you want a TL;DR, look at node.h, as well as the struct definitions
for root, output, workspace and container. Note that sway_output now
contains a workspaces list, and workspaces now contain a tiling and
floating list, and containers now contain a pointer back to the
workspace.
There are now functions for seat_get_focused_workspace and
seat_get_focused_container. The latter will return NULL if a workspace
itself is focused. Most other seat functions like seat_get_focus and
seat_set_focus now accept and return nodes.
In the config->handler_context struct, current_container has been
replaced with three pointers: node, container and workspace. node is the
same as what current_container was, while workspace is the workspace
that the node resides on and container is the actual container, which
may be NULL if a workspace itself is focused.
The global root_container variable has been replaced with one simply
called root, which is a pointer to the sway_root instance.
The way outputs are created, enabled, disabled and destroyed has
changed. Previously we'd wrap the sway_output in a container when it is
enabled, but as we don't have containers any more it needs a different
approach. The output_create and output_destroy functions previously
created/destroyed the container, but now they create/destroy the
sway_output. There is a new function output_disable to disable an output
without destroying it.
Containers have a new view property. If this is populated then the
container is a view container, otherwise it's a layout container. Like
before, this property is immutable for the life of the container.
Containers have both a `sway_container *parent` and
`sway_workspace *workspace`. As we use specific types now, parent cannot
point to a workspace so it'll be NULL for containers which are direct
children of the workspace. The workspace property is set for all
containers, except those which are hidden in the scratchpad as they have
no workspace.
In some cases we need to refer to workspaces in a container-like way.
For example, workspaces have layout and children, but when using
specific types this makes it difficult. Likewise, it's difficult for a
container to get its parent's layout when the parent could be another
container or a workspace. To make it easier, some helper functions have
been created: container_parent_layout and container_get_siblings.
container_remove_child has been renamed to container_detach and
container_replace_child has been renamed to container_replace.
`container_handle_fullscreen_reparent(con, old_parent)` has had the
old_parent removed. We now unfullscreen the workspace when detaching the
container, so this function is simplified and only needs one argument
now.
container_notify_subtree_changed has been renamed to
container_update_representation. This is more descriptive of its
purpose. I also wanted to be able to call it with whatever container was
changed rather than the container's parent, which makes bubbling up to
the workspace easier.
There are now state structs per node thing. ie. sway_output_state,
sway_workspace_state and sway_container_state.
The focus, move and layout commands have been completely refactored to
work with the specific types. I considered making these a separate PR,
but I'd be backporting my changes only to replace them again, and it's
easier just to test everything at once.
