030628c5ed SDRPostThread is better using try_push, restore previous audio-related code in DemodulatorInstance 2017-09-02 16:24:25 +02:00

c112026a2c Make processing queues timed-push, to be able to escape deadlocks. Rollback 'restart device when blocked' that is ineffective in practice. 2017-08-26 23:34:48 +02:00

e32e687fe8 Make IOThreads terminate() fully non-blocking and misc. 
- Thanks to timed-pop() usage, it is no longer needed to nudge queues with dummy to wake them
- Less bad luck to be stuck there
- Misc: leave the trace about the audio thread staturation, useful despite it raises some alarm among users...

c64baab99d Threads vs. Queues lifetimes, cleanups. 
- Ideally Queues must outlive the threads using them, but wasn't done so. Yes, std::shared_ptr them!
- Now queues are always valid in the context of the threads using them.
- No longer need tedious queues deallocation by the original owner.
- Misc cleanups.

3604b7f1ff Even better thread and application termination: 
- Now that timed-pop()/try_pop() prevent indefinite blocking it is best to flush() on thread stopping to unblock push()
- Reworked a bit the CubicSDR::OnExit() sequence, see comments.

8f608bbf5c Cleanup: remove some unused params and variables, conversion warnings seen with #550. 2017-05-29 20:22:10 +02:00

9b0ce69e8f Use the nuclear option to solve the hung problem: 
Besides deadlocks, a thread can in theory get stuck in a blocking pop(),
not seeing the stopping flag in particular. So assure liveness by making all
pop() timed pop.

77a82e1617 Another fix for the neverending hung application bugs: 
- Clear up DemodulatorInstance garbage collection, only do it in a single thread (AppFrame::OnIdle)
- Add a specific mutex lock for the list of deleted demodulators,
- Add a specific lock to control DemodulatorInstance thread lifetimes, protecting IsTerminated() of concurrent join and delete

4b323e9863 Make ReBuffer refcount management automatic, using std::shared_ptr: 
- No longer need to call setRefCount() / decRefCount()
- Restore old ThreadBlockingQueue using std::deque, for std::shared_ptr correct behaviour.

c7467a88bc BLOCKING_QUEUE: prepare by raising up max queue lenghts 
BLOCKING_QUEUE: Replaced ThreadQueue usage by ThreadBlockingQueue usage
BLOCKING_QUEUE: instrument all push() with timeouts, showed some call have to be non-blocking...
BLOCKING_QUEUE: tuned push()/try_push()

21c8a81c32 TH_CLEAN_3.5: push() cleanup side of things, assure SDRThread::readStream() to actually check for full + make ThreadQueue notify even in case on not-successfull push(), make it spam notify_all() everytime 2016-07-08 23:30:15 +02:00
