Denny	183eb2f7c7	Resolves #165 - P25 decoding channel stops arbitrarily and never recovers. ... Issue identified with Patch Group management and circular dependencies that can develop because of stale patch groups. Refactored all patch group management into a new PatchGroupManager. Patch groups are now automatically deleted if we don't receive any update messages within 5 seconds. The PatchGroupAlias was also updated to not roll-up attributes from subordinate patched group aliases when those aliases are also patch group aliases -- this eliminates the circular dependency chaining. Added IOverflowListener interface and updated Sources to support overflow listeners. Updated ChannelState to register as an overflow listener so that it can visually depict to the user when the channel enters/exits source overflow state. Added new color pattern for OVERFLOW with yellow text on red.	2017-02-10 06:36:57 -05:00

Denny	74c15d530b	Resolves #164 - USB time out while processing buffer transfers. Decreases periodicity of processing the LibUsb timeout handler from 9 milliseconds to 5 milliseconds to reduce chance that buffers are not being serviced in time.	2017-01-29 11:02:12 -05:00

Denny	a302d098de	126 - Significant improvement in processor and memory utilization. Refactors all USB tuner sample processing with a new USBTransferProcessor class. LibUSB transfer timeout processing is now consolidated under the TunerManager and tuners register with this singleton to auto-start or auto-stop USB bulk transfer processing. Resolves long-standing issue impacting multi-tuner use where the second and subsequent tuners may have been routinely starved for LibUSB processing time under heavy-loading. All tuner buffer threaded processing is now handled as runnables in the scheduled thread pool, eliminating tuner-dedicated processing threads. Added tuner buffer size management to prevent memory blow-out when down-stream processing is either lagging or impacted by java garbage collection operations. Both tuners and individual DDC channels now have bounded sample buffer queues that automatically enter and exit overflow mode when predefined max/reset thresholds are met. When any queue goes into overflow mode, sample buffers are simply dropped in favor of preserving program/memory stability.	2017-01-28 09:08:11 -05:00
