* native: rework handling of seeks that depend on variables the client does ↵Lennart Poettering2010-02-091-2/+4
| | | | | | | | | | | | not know anything about All seeks/flushes that depend on the playback buffer read pointer cannot be accounted for properly in the client since it does not know the actual read pointer. Due to that the clients do not account for it at all. We need do the same on the server side. And we did, but a little bit too extreme. While we properly have not applied the changes to the "request" counter we still do have to apply it to the "missing" counter. This patch fixes that.
* native: fix request counter miscalculationsLennart Poettering2010-02-091-55/+46
| | | | | | | | | | | | | Do not subtract bytes the client sends us beyond what we requested from our missing bytes counter. This was mostly a thinko that caused servers asking for too little data when the client initially sent more data than requested, because that data sent too much was accounted for twice. This commit fixes this miscalculation. http://bugzilla.redhat.com/show_bug.cgi?id=534130

* Make sure we don't get stuck when prebuf is too highLennart Poettering2009-04-061-29/+23
| | | | | | | | If prebuf is greater than tlength minus minreq we might end up waiting for the buffer to fill up further however without ever asking for more data from the client since less minreq bytes might be missing. This fixes bug #440

* rework memory block management to be thread-safe and mostly lock-free.Lennart Poettering2006-09-261-5/+5
| | | | | | | | | | | | | | | | | | | | | pa_memblock is now an opaque structure. Access to its fields is now done through various accessor functions in a thread-safe manner. pa_memblock_acquire() and pa_memblock_release() are now used to access the attached audio data. Why? To allow safe manipulation of the memory pointer maintained by the memory block. Internally _acquire() and _release() maintain a reference counter. Please do not confuse this reference counter whith the one maintained by pa_memblock_ref()/_unref()! As a side effect this patch removes all direct usages of AO_t and replaces it with pa_atomic_xxx based code. This stuff needs some serious testing love. Especially if threads are actively used. git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@1404 fefdeb5f-60dc-0310-8127-8f9354f1896f

* Rework memory management to allow shared memory data transfer. The central ideaLennart Poettering2006-08-181-5/+2
| | | | | | | | | | | | | | | is to allocate all audio memory blocks from a per-process memory pool which is available as read-only SHM segment to other local processes. Then, instead of writing the actual audio data to the socket just write references to this shared memory pool. To work optimally all memory blocks should now be of type PA_MEMBLOCK_POOL or PA_MEMBLOCK_POOL_EXTERNAL. The function pa_memblock_new() now generates memory blocks of this type by default. git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@1266 fefdeb5f-60dc-0310-8127-8f9354f1896f
