This no longer exposes the pipewire socket to the container, and instead mediates access via pipewire-pulse. This makes insecure parts of the protocol inaccessible as explained in the doc comment in hst.
Closes #29.

This is for setting up the pipewire-pulse container in shim, for #29.

This is a private work directory owned by the specific shim. Useful for sockets owned by this instance of the shim and requires no direct assistance from the priv-side process.

This method can result in an error targeting it, so it is handled here. This change also causes a call to Create to also Core::Sync, as it should have done.

This proxy can be destroyed by sending a Core::Destroy targeting it. This change implements the Destroy method by embedding destructible.

This change reorders and groups struct elements. This improves readability since this struct holds a lot of state loosely related to each other.

This change also implements pending destructible check on Sync. Destruction method should always be implemented as a wrapper of destructible.destroy.

Turns out the PipeWire server does not expect a value of type None here at all.

Nothing uses this right now, this would have to be called by wrapper methods on Registry that would search the objects

This now marshals into a value of type None when the slice is nil, and correctly unmarshals from type None.
Signed-off-by: Ophestra <cat@gensokyo.uk>
|

This now calls unmarshalCheckTypeBounds to advance to the next message. Additionally, handling for None value is relocated to a function for reuse by other types.

A nil spa_dict results in a None type value being sent over the wire.

These do not belong under Context, and is an early implementation limitation that carried over.

Receiving this event indicates something has gone terribly wrong somehow, and ignoring Core::BoundProps causes inconsistent state anyway.

This is emitted by the server when a proxy id is removed for any reason. Currently, the only path for this to be emitted is when a global object is destroyed while some proxy is still bound to it.

Skipping events can cause local state to diverge from the server.

This flushes message buffer before queueing the event expecting the error. Since this is quite useful and relatively complex, it is relocated to a method of Context.

These have similar semantics to equivalent Wayland security-context-v1 fields.

The error string itself is descriptive enough, so use it as the error message directly.

This requires error handling infrastructure in Core that does not yet exist, so it is not exported for now. It has been manually tested via linkname against PipeWire.

This is emitted by PipeWire when a global object disappears, because PipeWire insists that all clients that had called Core::GetRegistry must constantly sync its local registry state with the remote.

Unused in hakurei but could be useful when the package is moved out of internal.

This was left in consume when relocating per-roundtrip code out of the per-receive consume method.

The error is handled later, clobbering it here breaks error handling when SCMs are present.

Remote sequence sometimes start with a non-zero value, and keeps the same value for a while before going back to zero. Conditions for reproducing this behaviour is not yet known. This change works around this behaviour.

This fully replaces PulseAudio with PipeWire and enforces the PulseAudio check and error message. The pipewire-pulse daemon is handled in the NixOS module.
Closes #26.

This is slightly counterintuitive, but it turned out well under this framework since the daemon backs its target file.

This is very simple and takes almost no inputs. This is not yet hooked up to anything to prevent breaking any existing behaviour.

This is not defined anywhere in upstream PipeWire, no idea why.

These are for #26. None of them are implemented yet. This fixes up test cases for the change to happen. Existing source code and JSON configuration continue to have the same effect. Existing flags get its EPulse bit replaced by EPipeWire.

Tests for this Op happens to be the best out of everything due to the robust infrastructure offered by internal/pipewire.
This is now ready to use in internal/outcome for implementing #26.

The PipeWire Op check cannot be made parallel due to the OS interaction.

There is currently no known message that will get the PipeWire server to emit this event. It should be handled regardless.

This adds checking of FileCount while writing a message. Message encoding is relocated to an exported method to be used externally, probably for test stubbing.

This behaviour is a bit messy and checks what appears to be a windows-specific environment variable for some reason. Keeping everything intact regardless to match upstream behaviour.

Removing the pathname socket used to be handled separately, now it is done during the Close call.
Signed-off-by: Ophestra <cat@gensokyo.uk>

This sets up close pipe and socket internally, and exposes the resulting pathname socket and close_fd cleanup as an io.Closer.

This is not guaranteed to have completed after a roundtrip. This is leftover from when Roundtrip also sent and waited for sync.

This makes it easier to handle resources who only needs to stay alive before the next sync.

This should not be handled on every receive as it could cause valid (though impossible in current upstream implementation) messages to be rejected and raise a protocol error.

This change fixes handling of non-fatal errors during a roundtrip as there can be multiple receive calls per roundtrip.

This name is more correct since it does not roundtrip, but receives messages. This is also more consistent with the method on event proxies.
