When the last output is disconnected, output_disable is called like
usual and evacuates the output to the root->saved_workspaces list. It
then calls root_for_each_container to remove (untrack) the output from
each container's outputs list. However root_for_each_container did not
iterate the saved workspaces, so when the output gets freed the
containers would have a dangling pointer in their outputs list. Upon
reconnect, container_discover_outputs would attempt to use the dangling
pointer, causing a crash.
This makes root_for_each_container check the saved workspaces list,
which fixes the problem.
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.
When we eventually implement `workspace <ws> gaps inner|outer <px>`,
we'll need to store the gaps settings for workspaces before they're
created. Rather than create a workspace_gaps struct, the approach I'm
taking is to rename workspace_outputs to workspace_configs and then add
gaps settings to that.
I've added a lookup function workspace_find_config. Note that we have a
similar thing for outputs (output_config struct and output_find_config).
Lastly, when freeing config it would create a memory leak by freeing the
list items but not the workspace or output names inside them. This has
been rectified using a free_workspace_config function.
This involves setuid'ing swaylock, which then forks and drops perms on
the parent process. The child process remains root and listens on a pipe
for requests to validate passwords against /etc/shadow.
view_is_visible would return false, which meant the view wouldn't
receive a frame done event. view_is_visible needs to make an exception
for floating containers.
This also moves the workspace_is_visible check to an earlier location
for performance reasons.
This commit fixes a segfault in swaybar on FreeBSD that was caused by
using getdelim with EOF as delimiter on an infinite stream. The FreeBSD
implementation handles the "no more data, delimiter not found, and EOF
not reached" scenario as an error, so it can't be used to read the
output of status command. This commit replaces the getline/getdelim
calls with reading all available data from the stream in one go.
This commit replaces the non-standard SOCK_NONBLOCK and SOCK_CLOEXEC
flags with two fcntl calls. This makes the file POSIX 2001 compliant,
thus it is no longer necessary to conditionally define, or use internal
(__BSD_VISIBLE) feature test macros.
This will restrict the default namespace set on FreeBSD to the C11
standard (everything is visible by default), which will prevent possible
conflicts with symbols hidden behing __BSD_VISIBLE.
When a view unmaps, we start a transaction to destroy the container,
then when the transaction completes we destroy the container and unset
the view's container pointer. But if the view has remapped in the
meantime, the view's container pointer will be pointing to a different
container which should not be cleared.
This adds a check to make sure the view is still pointing to the
container being destroyed before clearing the pointer. The freeing of
the title format is also removed as it is already freed when the view
destroys in view_destroy.
If the output being disconnected contains views, and the views are being
relocated to another output of a different size, a transaction must
occur to reconfigure them. This means by the time
container_discover_outputs is called, the output is already disabled and
wlr_output is NULL.
I considered making it check output->wlr_output, but output->enabled
should work just as well and is more descriptive.
render_background_image alters the scale that cairo uses. Depending on
the image mode, resolution, and image size, this may cause the surface
to be rendered increasingly smaller. By calling cairo_save and
cairo_restore, any changes to the cairo settings by the function are
not kept as a side effect.
The surface that swaybg uses is also now cleared before rendering a frame.
This is needed to avoid artifacts on resolution or scale changes with
certain combinations of image modes, resolutions, and image sizes. This
was also part of the increasingly smaller background visual since it
made it so it was not obvious the region being rendered to was smaller
and caused an increasing number of smaller images to be appear for each
hotplug.
