Hyprland hasn't been using TCP sockets for IPC since the first release,
so this getaddrinfo call and its result was never needed.
Additionally, it leaks the `aiRes`, causing test failure under ASan.
Allows us to disable modules entirely when socket connection isn't
working. This is similar to how sway handles their socket connections
disabling modules. This supports a single waybar config for multiple
IPCs.
Gracefully handle lack of response from the IPC. If socket isn't
available, we already log the IPC isn't running. We dont need to crash
program just because we couldn't get responses. We can just return an
empty object.
I'd like to ignore some windows from having icons or empty space taken
on the bar. By filtering out empty repr we can supply rewrite rules that
will ignore them from being processed and showing an empty space or
default icon.
IPC messages are parsed in a dedicated thread, and the thread terminates when
an exception is not caught, which causes the waybar process to crash with
SIGABORT.
While this issue might be related to Hyprland, it is really annoying to see
waybar crash. It would be better to catch those exceptions and report errors
instead of crashing.
Fixes#2945
Split the config and rule persistency in 2 attributes, one storing the
persistency as set in Waybar's config, the other one storing the
persistency as set in Hyprland.
It fixes some conflicts between the persistency state of a workspace as
set in Waybar's config and its dynamic state in Hyprland.
It allows to remove a persistent workspace in Waybar if this workspace
is removed from Hyprland and if the workspace is not set as persistent
in Waybar's config.
