2017-02-12Fix atomic event executionDavid Robillard1-24/+28
2017-01-18Fix invalid cross-thread use of mutexDavid Robillard1-1/+17
Instead of abusing store mutex for this purpose, extend blocking mechanism of the PreProcessor (designed for atomic bundle execution) to support execution of individual atomic events which must be executed before the next event can be pre-processed.

2016-10-02Implement microsecond clock for Linux and OSXDavid Robillard1-2/+2
2016-10-02Defer graph compilation in atomic bundlesDavid Robillard1-1/+13
This avoids situations like compiling a graph hundreds of times when it is loaded because it has hundreds of nodes and each event triggers a re-compile. This speeds things up dramatically, but exacerbates the theoretical problem of there not being enough time in a cycle to execute a bundle. As far as I can tell, the execute phase of events is very fast, so hundreds or thousands can easily run in a tiny fraction of the process cycle, but this still needs resolution to be truly hard real-time. What probably needs to happen is that all context and state used to process is moved to CompiledGraph and nodes do not access their own fields at all, but have some references into the CompiledGraph. This way, a compiled graph is separate from its "source code", and an old one could continue to be run while a new one is beng applied across several cycles.

2016-07-30Fix stall by making PreProcessor tick periodicallyDavid Robillard1-1/+5
I am not sure exactly what scenarios cause this to happen, every event should post to the semaphore, but having the PreProcessor thread tick idly doesn't hurt anything and resolves the issue.

2012-05-09Simply event interface design and make only one pre-process thread.David Robillard1-0/+125
This makes event pre-processing actually safe for multiple interfaces since multiple events will never be pre-processed simultaneously and the pre-process order is definitely the same as the execute order. git-svn-id: http://svn.drobilla.net/lad/trunk/ingen@4323 a436a847-0d15-0410-975c-d299462d15a1
