- Limit WAV size to 2GB for maximum compatibility,
- Continue recording on another file when size gets too big (XXX_001.wav, then XXX_002.wav and so on)
- The sequence assure up to 2000GB worth of recording which should be enough
- Changed file pattern to international Year.Month.Day so its recognizable whether you are English of French or whatever :)
- 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...
- 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.
- 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.
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.
- 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
The problem lies in DemodulatorPreThread:
- settings were actually get/set unprotected from concurrent access (bendwiths, frequencies, sample rates...etc) so make them atomic.
- If bandwith has changed, return the new value instead of the current one, just like frequencies.
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()
make process() a true interface as strong hint for derived classes,
plus misc define added for understanding.
BUGFIX: FFTDataDistributor loses incoming samples when compacting internal buffers.
BUGFIX2: FFTDistributor: Frozen Waterfall if internal buffer is no bigger than fftSize
