* rework memory block management to be thread-safe and mostly lock-free.Lennart Poettering2006-09-2636-502/+993
| | | | | | | | | | | | | | | | | | | | | 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

* add a tiny wrapper around libatomic_ops: pa_atomic_int_t and pa_atomit_ptr_t.Lennart Poettering2006-09-081-0/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reasoning: This wrapper fixes a few API issues I found with atomic_ops: * AO_t is an int, which can be written to with "=". pa_tomic_int_t however is a struct which due to type-safety enforces proper access with pa_atomic_xx(). (Inspired by the way the Linux kernel handles this) * AO_load()'s parameter is lacking a "const" * Explicitly choosing the proper memory barrier for each call is very difficult and especially hard to debug because most CPUs support only two different barrier types which the eight types defined by atomic_ops are mapped to. Most other software (i.e. glib, Linux kernel) which provides atomic variable access usually do a full barrier in all cases and so should we. Eventually we might choose to add additional memory barrier calls, in which case we can add special versions of the current function with special suffixes. * The function names are unnecesarily long * Atomic pointer accesses are only supported with manual casts. The new pa_atomic_xxx interface borrows heavily from the GLib and Linux kernel atomicity API, though it is different from both of them. In addition this abstract API makes it easy to port PA to different atomicty APIs, if libatomic_ops should ever become out-of-fashion or if the system OS supports atomic primitives anyway. git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@1381 fefdeb5f-60dc-0310-8127-8f9354f1896f
