[pulseaudio-discuss] [PATCH 00/12] A new ringbuffer based protocol for PulseAudio

[David Henningsson]

Third iteration.

Changes since previous version:

 * it's now srbchannel (Shared RingBuffer) instead of srchannel
   (srchannel could easily be read as src-hannel)

 * srbchannel test added on pstream level, also tests the pstream on
   the iochannel btw.

 * protocol-native has a new module parameter "srbchannel", which defaults
   to true. Set it to false to use the iochannel only.

 * srbchannel setup is now acked by client, and packets are sent in a
   different order. No srbchannel without both parties agreeing on it.

 * Pstream: fixed the actual switching to be slightly more robust, and
   only happening when the output buffer is empty.

 * fixed pa_iochannel_read_with_ancil to fall back to pa_iochannel_read
   in case it was called on a non-socket.

David Henningsson (11):
  creds: Add struct for ancillary data
  iochannel/pstream/pdispatch: Add support for receiving file
    descriptors
  iochannel/pstream: Support sending file descriptors
  srbchannel: Add the shared ringbuffer object
  shm: Allow to open shm in writable mode
  memblock, pstream: Allow send/receive of remote writable memblocks
  core: Add a second rw mempool
  pstream: Allow reading/writing through srbchannel
  Protocol, client: Add commands to enable srbchannel
  protocol-native: Enable srbchannel
  tests: Add pstream/srbchannel test

Peter Meerwald (1):
  tests: Adapt memblock-test to changed pa_memimport_get()
