Brian Ashworth f7f5b172a0 sway-input.5: document wildcard and identifier troubleshooting
This documents the wildcard character for both inputs and seats. There
is also a tip added on trying the wildcard to verify a setting if the
identifier does not appear to be working.

Brian Ashworth 272ca06171 Fix reload freeze when not modsetting current mode
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.

Brian Ashworth 96de2b539c apply_output_config: dpms on before modeset
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.

Brian Ashworth e8c472aee9 seatop_move_tiling: do not move to descendant
In seatop_move_tiling, it is possible to cause a stack overflow by
dragging a container into one of its descendants. This disables the
ability to move into a descendant.

Brian Ashworth ab42874f71 seat: allow tree focus changes while layer focused
This allows the focused inactive tree node and visible workspaces to be
changed while a surface layer has focus. The layer temporarily loses
focus, the tree focus changes, and the layer gets refocused.

Brian Ashworth 9b8249c350 seatop_move_tiling: use tab/stack parent not self
When moving a descendant of a tabbed or stacked container, it is possible
for the target node to be the node being moved. This causes a segfault in
`handle_finish` since the node will be detached and then attempted to be
attached to it own parent, which is NULL due to the detach. In this
case, the target node should not be set to the node being moved, but the
parent of the node. This also allows for a descendant of a tabbed or
stacked container to be dragged out of the tabs/stacks and to be a
sibling of the tabbbed/stacked container, which was not previously
possible.

Brian Ashworth d168d65f2c subsurface_get_root_coords: break on NULL
It is possible for `wlr_surface_is_subsurface` to return true, but
`wlr_surface_from_wlr_surface` to be NULL. This adds a NULL check to the
value returned by `wlr_surface_from_wlr_surface` and breaks out of the
while loop in `subsurface_get_root_coords`.

Rouven Czerwinski 605e515a93 fix double free for mode toggle if bar was invisible
If the bar was set to "invisible" and subsequently "toggle" was send twice, the

Fix this by not requiring the bar->mode to be "hide" and instead show it
unconditionally, because it was either hidden or invisible.

Brian Ashworth 995b6edab6 container_at_stacked: skip titles when zero pixels
It is possible to make the title bars have a zero pixel height while
stacked, by using a blank font and no padding. This causes a division by
zero when attempting to calculate the child index in
container_at_stacked, which then results in a segfault when attempting
to access the child at that bad index (INT_MIN). This just skips the
check to see if the cursor is over a title bar of a child of a stacked
container when the title bar height is zero since there will be no title
bars.

Brian Ashworth f5190d1f79 bar_cmd_modifier: add support for none
sway-bar(5) documents `modifier none`, which comes from i3. This
implements the functionality for `modifier none` since it was not
previously implemented. The bar modifier toggles visibility of the bar
when the bar mode is set to hide. When the bar modifier is set to
`none`, the ability to toggle visibility of the bar will be disabled.

Brian Ashworth ec5da0ca5b seat_configure_tablet_tool: configure xcursor
Since a tablet tool provides the WL_SEAT_CAPABILITY_POINTER capability,
sway will attempt to use the xcursor manager to set a cursor image. If
the tablet tool was the first (and possibly only) device to provide the
capability for the seat, the xcursor manager was not being configured
before attempting to set a cursor image. This was due to
`seat_configure_xcursor` only being called in `seat_configure_pointer`.
Since the xcursor manager was NULL in this case, it would cause a
segfault when attempting to set a cursor image. This adds a call to
`seat_configure_xcursor` in `seat_configure_tablet_tool` to ensure that
the seat has a xcursor manager.

Brian Ashworth 5a32a74b2d load_main_config: use given path, store realpath
Since `load_include_config` compares against the realpath of a config
file when checking if a config has already been added, the main config's
realpath has to be added to the config_chain.

However, includes from the main config should be processed relative to
the path given to allow for symbolic links. This stores the realpath in
`config->config_chain`, but uses the given path for all other
operations.

Brian Ashworth ee56428b64 Clarify error for options and positional args
When both options and positional arguments are given, sway would print
the error `Don't use options with the IPC client`. Over the past
several months, it seems like users are including this error message in
issues instead of a debug log due to not understanding that the error
message means there is an issue with their command.

This makes the error message more verbose and will hopefully make it so
more users understand that the message is not a bug in sway, but with
the command used.

Brian Ashworth 89afb761ba output_cmd_background: fix no file + valid mode
If output_cmd_background is given a valid mode as the first argument,
then there is no file given and an error should be returned.

join_args should not be called with an argc of zero since it sets the
last character to the null terminator. With an argc of zero, the length
is zero causing a heap buffer overflow when setting the byte before the
start of argv to '\0'. This probably will not ever generate a segfault,
but may cause data corruption to whatever is directly before it in
memory. To make other such cases easier to detect, this also adds a
sway_assert in join_args when argc is zero.

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.

- In main, `goto` statements have been added after the `sway_terminate`
calls instead of wrapping every block in `if (!terminate_request)`
- Unnecessary NULL-checks around calls to free in `main` have been
removed
- Deferred command execution has been extracted to a separate function
and the `Running deferred commands` log message will not be shown when
there are no deferred commands.

Ryan Dwyer 0a9ff774ad Center surface inside container when it's too small
The goal here is to center fullscreen views when they are both too small
for the output and refuse to resize to the output's dimensions. It has
the side effect of also centering the view when it's too small for its
container.

Example clients that have this behaviour are emersion's hello-wayland
and weston.

It works by introducing surface_{x,y,width,height} properties to the
container struct. The x and y represent layout-local coordinates where
the surface will be rendered. The width and height are only used to
track the surface's previous dimensions so we can detect when the client
has resized it and recenter and apply damage accordingly.

The new surface properties are calculated when a transaction is applied,
as well as when a view resizes itself unexpectedly. The latter is done
in view_update_size. This function was previously restricted to views
which are floating, but can now be called for any views.

For views which refuse to resize *smaller* than a particular size, such
as gnome-calculator, the surface is still anchored to the top left as
per the current behaviour.

Instead of having NULL workspace->output pointers, use a noop output.
This should be safer.

Fix one remaining wlr_log call 2019-01-21 13:02:03 +01:00
M Stoeckl 1211a81aad Replace wlr_log with sway_log
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.

Brian Ashworth 91c1f44956 input_cmd_events: allow toggle modes to be listed
This extends `input <identifier> events toggle` to allow for an optional
list of modes to toggle through. If no event modes are listed, all
supported modes are cycled through (current behavior). If event modes
are listed, they will be cycled through, defaulting to the first mode
listed when the current mode is not in the list. This modes listed will
also not be checked to see if the device supports them and may fail.

Fix re-enabling outputs gaining a CRTC
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.

emersion 3b7a7462a2 Fix crash in cursor_rebase with multiple screens
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.
