Linux power_supply sysfs interface allows checking if the battery powers
the whole system or a specific device/tree of devices with `scope`
attribute[1]. We can use it to skip the non-system power supplies in the
battery module and avoid adding HIDs or other peripheral devices to the
total.
The logic is based on UPower, where it is assumed that "Unknown" devices
or devices without a `scope` are system power supplies.

As we always use the enum to compare or initialize uint32_t values, it
would be better to declare it with the right type. This way we could
avoid `-Wnarrowing` warnings or unnecessary type casts.
Stop using private implementation details of the `formatter<std::tm>`.
We never needed anything from the class besides the format specifier,
which is easily obtainable with public API.
Allow changing existing modes and adding new ones via `modes`
configuration key.
`modes` accepts a JSON object roughly described by the following type
```typescript
type BarMode = {
layer: 'bottom' | 'top' | 'overlay';
exclusive: bool;
passthrough: bool;
visible: bool;
};
type BarModeList = {
[name: string]: BarMode;
};
```
and will be merged with the default modes defined in `bar.cpp`.
Note that with absence of other ways to set mode, only those defined in
the `sway-bar(5)`[1] documentation could be used right now.

Intermittent CI failures without any useful diagnostics could be caused
by the OOM killer. 1024MB is not really enough to run 3 parallel jobs
with a modern C++ compiler.
`show_all` call from `Tray::update` attempts to walk the widget tree and
make every widget visible. Since we control individual tray item
visibility based on `Status` SNI property, we don't want that to happen.
Modify `Tray::update` to control the visibility of a whole tray module
only and ensure that the children of `Item` are still visible when
necessary.
On the `Passive` value of `Status` tray items would be hidden unless
`show-passive-items` is set to true.
On the `NeedsAttention` value of `Status` tray items will have a
`.needs-attention` CSS class.
The changes in GCC 11.x made `std::condition_variable` implementation
internals `noexcept`. `noexcept` is known to interact particularly bad
with `pthread_cancel`, i.e. `__cxxabiv1::__force_unwind` passing through
the `noexcept` call stack frame causes a `std::terminate` call and
immediate termination of the program
Digging through the GCC ML archives[1] lead me to the idea of patching
this with a few pthread_setcancelstate's. As bad as the solution is, it
seems to be the best we can do within C++17 limits and without major
rework.

Moving rfkill to the main event loop had unexpected side-effects.
Notably, the network module mutex can block all the main thread events
for several seconds while the network worker thread is sleeping.
Instead of waiting for the mutex let's hope that the worker thread
succeeds and schedule timer thread wakeup just in case.
Open rfkill device only once per module.
Remove rfkill threads and use `Glib::signal_io` as a more efficient way
to poll the rfkill device.
Handle runtime errors from rfkill and stop polling of the device instead
of crashing waybar.
Kernel 5.11 added one more field to the `struct rfkill_event` and broke
unnecessarily strict check in `rfkill.cpp`. According to `linux/rfkill.h`,
we must accept events at least as large as v1 event size and should be
prepared to get additional fields at the end of a v1 event structure.
Multiple .done events may arrive in batch. In this case libwayland would
queue xdg_output.destroy and dispatch all pending events, triggering
this callback several times for the same output.
Delete xdg_output pointer immediately on the first event and use the
value as a guard for reentering.
At this point we're not awaiting any protocol events and flushing
wayland queue makes little sense. As #1019 shows, it may be even harmful
as an extra roundtrip could process wl_output disappearance and delete
output object right from under our code.
Ignore any further xdg_output events. Name and description are constant
for the lifetime of wl_output in xdg-output-unstable-v1 version 2 and we
don't need other properties.
Fixes#990.
Destroy request is not specified for foreign toplevel manager and it
does not prevent the compositor from sending more events.
Libwayland would ignore events to a destroyed objects, but that could
indirectly cause a gap in the sequence of new object ids and trigger
error condition in the library.
With this commit waybar sends a `stop` request to notify the compositor
about the destruction of a toplevel manager. That fixes abnormal
termination of the bar with following errors:
```
(waybar:11791): Gdk-DEBUG: 20:04:19.778: not a valid new object id (4278190088), message toplevel(n)
Gdk-Message: 20:04:19.778: Error reading events from display: Invalid argument
```
GDK Wayland backend can emit two events for mouse scroll: one is a
GDK_SCROLL_SMOOTH and the other one is an emulated scroll event with
direction. We only receive emulated events on a window, thus it is not
possible to handle these in a module and stop propagation.
Ignoring emulated events should be safe since those are duplicates of
smooth scroll events anyways.
Fixes#386

Invisible bar on a `top` layer would still intercept pointer events and
stop them from reaching windows below. Always changing the layer to
to `bottom` along with making bar invisible would prevent that.
Extract two surface implementations from the bar class: GLSSurfaceImpl
and RawSurfaceImpl. This change allowed to remove _all_ surface type
conditionals and significantly simplify the Bar code.
The change also applies PImpl pattern to the Bar, allowing to remove
some headers and fields from `bar.hpp`.
Previous attempts to use auto exclusive zone from gtk-layer-shell failed
because gls was expecting real booleans (`TRUE`/`FALSE`) as set_anchor
arguments. With that being fixed, gtk_layer_auto_exclusive_zone_enable
makes gls handle everything related to the bar resizing.
The only remaining purpose of onConfigureGLS is to log warnings and bar
size changes; gtk-layer-shell code path no longer needs saved width_ or
height_ values.
It's not allowed to bind to a higher version of a wayland protocol than
supported by the client. Binding wlr-foreign-toplevel-manager-v1 v3 to
a generated code for v2 causes errors in libwayland due to a missing
handler for `zwlr_foreign_toplevel_handle_v1.parent` event.
Read `layer`, `exclusive`, `passthrough` into a special mode "default".
Drop `overlay` layer hacks, as it's easier to use `"mode": "overlay"`
for the same result.
Use `mode` (`waybar::Bar::setMode`) as a shorthand to configure bar
visibility, layer, exclusive zones and input event handling in the same
way as `swaybar` does.
See `sway-bar(5)` for a description of available modes.
Implement a wrapper over Glib::Dispatcher that passes the arguments to
the signal consumer via synchronized `std::queue`.
Arguments are always passed by value and the return type of the signal
is expected to be `void`.
If the bar is using initial size from the config (i.e both width and
height are set and resize is not required), GtkWindow configure event
is is not emitted. Initialize exclusive zone earlier for that case.
Fixes#609
Ipc destructor closes socket and thus wakes up SleeperThread which was
waiting for socket data in Ipc::handleEvent.
Ipc::handleEvent then proceeds with sending signal to already destroyed
object, causing heap-use-after-free Address Sanitizer error.
std::unique_ptr is not required here as the only benefit it gives is
stability of address on vector resize and it's easy to invalidate it
accidentaly. std::list provides the same guarantee of stable addresses
of the elements and correct destruction while avoiding smart pointer
overhead.
Also fixes#554, caused by incorrect usage of std::remove_if.
To enable: use sway >= 1.2, compile waybar with `-Dgtk-layer-shell=enabled` meson option.
Original behavior could be restored at runtime by setting `"gtk-layer-shell": false` in waybar config.
gtk-layer-shell wants Gdk::Monitor instead of wl_output;
change code to deal with Gdk objects and slightly simplify it.
Requires gtkmm 3.22.0+ (first release with Gdk::Monitor support).
