Remove signals.
Rename callbacks -> events, use listeners to listen for events.
Callbacks are still used in spa for things you can listen to only
once.
Make it possible to add more permissions to an object than just visible
or not. Pass these permissions to the client. This way we can make a
difference between being able to see and read, modify or query an
object. More permissions can be added later when needed. Because the
permissions is set on the resource by the access control module, the
implementations can check if the right permission is set before doing
anything.
Make a new method that can take a local node and run it in a remote
pipeline. This basically replaces all functionality of the streams
and more.
Add 2 examples for exporting a sink and a v4l2 node
Make some more things const
Cleanups
Make it possible to do things when the node needs scheduling. The
default node will schedule the local pipeline but the remote node might
also schedule the remote pipeline.
Fix docs
Add some more versions to interfaces
Make types for the various proxy object + inline methods that does type
checking and create proxys etc.
Set owner client of client-nodes in the properties
Pass type to bind to in create-node
Don't place global id in the info structs
Improve registration of marshal functions
Pass more types around as ids
Add hooks that contain protocol specific interfaces that can be used
to extend the protocol. This makes it possible to add new interfaces
to the protocol and implement the protocol specific data transport.
Move these protocol specific extension to the extensions directory.
Add GAsyncReadyCallback to the introspection API. This makes it possible
to report errors in the future. Don't pass NULL in the callback anymore
now that we have the Ready callback. We also don't need to have a return
value from the callback because now we can cancel any iteration by using
the GCancelable.
Make pinos_context_info_finish() to get the final result/error of
introspection.
Update tools for new API
Check if we got tmpfile memory and if we do, don't bother waiting for
the release-fd message but unref the memory directly. We know the memory
is allocated from our allocator and that we won't reuse it.
Track the fd indices we sent to Pinos and free the associated buffer
when Pinos sends us release-fd. Only do this for non tempfile fds, as we
made the tmpfile ones ourselves and we're not going to reuse them.
Handle application/x-pinos specially; track all the fd indices in the
buffers and send a release-fd message when the buffer is freed.
We can then use the payloader also in the client-source to handle the
release-fd messages correctly.
The caps we stream between the src and sink are always
application/x-pinos. Keep the negotiated format ouside of the
capsfilter in a separate variable. We can then also avoid a query
to get the format.
If we are using the original buffer fd without copying it into a temp
file we need to make sure the memory stays alive and is not reused until
all clients are done with it.
To do this, track what fd ids are in the outgoing buffers and ref the
original buffer. We also need to know when a message is sent to a client
and when that client does a release-fd on the fd index. This is done
with some new events on the multisocketsink.
Every time a message is sent to a client we hash the fd index in it and
ref the buffer in a per-client hash table (on the socket). Every time we
receive release-fd we remove the fd index from the hash and unref the
buffer again.
Clients that are killed get their socket removed, which also cleans up
the hashtable and frees the memory again.
