The interface provided by net is not used here and is a leftover from a previous implementation. This change removes it.

The interface does not expose underlying kernel notification mechanisms. This change removes the need to poll in situations were the next call might block.
This is made cumbersome by the SyscallConn interface left over from a previous implementation, it will be replaced in a later commit as the current implementation does not make use of any net.Conn methods other than Close.

When returned wrapped as a syscall error, these are impossible to recover from, so wrap them as a fatal error.

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.

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

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.

Receiving this event indicates something has gone terribly wrong somehow, and ignoring Core::BoundProps causes inconsistent state anyway.
Signed-off-by: Ophestra <cat@gensokyo.uk>
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.

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.

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.
Signed-off-by: Ophestra <cat@gensokyo.uk>
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.

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.
Signed-off-by: Ophestra <cat@gensokyo.uk>
There is currently no known message that will get the PipeWire server to emit this event. It should be handled regardless.
Signed-off-by: Ophestra <cat@gensokyo.uk>
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.

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 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.
Signed-off-by: Ophestra <cat@gensokyo.uk>
This change fixes handling of non-fatal errors during a roundtrip as there can be multiple receive calls per roundtrip.
Signed-off-by: Ophestra <cat@gensokyo.uk>
This name is more correct since it does not roundtrip, but receives messages. This is also more consistent with the method on event proxies.

The PipeWire protocol does not work with Go abstractions. This change makes relevant methods call sendmsg/recvmsg directly.

These are PipeWire spa_dict keys. Interestingly many keys in the sample are undefined and appear as magic strings in upstream source code.

These are mostly small formatting changes, with the biggest change being to UnexpectedEOFError where its kind is now described as part of the error type.

This should make things easier to navigate, and possible to fully automatically generate the constants in the future.
Signed-off-by: Ophestra <cat@gensokyo.uk>
These errors are recoverable and should not terminate event handling. Only terminate event handling for protocol errors or inconsistent state that makes further event handling impossible.

These proxies (with special cases documented in the implementation) are only safe for use after acknowledgement from the server.
