| * | Fix deadlock in AudioFifo. | Greg | 2016-12-12 | 1 | -0/+31 |
| | | | | | | | | | | | | | | | | | | | | | | | | | The deadlock scenario is the following: 1) AudioFifo is used with wait on write and read 2) Producer Thread calls write(). The buffer is full, then it gets into the while(available() == buffer.length) loop 3) a context switch happens right there, BEFORE readSemaphore.wait() 4) Consumer Thread calls read() multiple times until it depletes the buffer, then ends up in writeSemaphore.wait() 5) context switch back to the Producer Thread, which now calls readSemaphore.wait() Deadlock: the buffer is empty, and nobody is going to signal the producer that there is availability. This can be reproduced with a simple stress test. I added the stress test which is simply a copy of an existing one, with a very large value for the chunk variable. The race condition is more likely to be hit when the buffer is small, but I have hit it in "production" with 32K buffers, while generating large files (a few hundred megabytes). I am not sure the performance implications of the change, as my use cases are non-realtime. Still, all the tests pass. | ||||
