As follow-up to the rework of thread-handling, likewise also the implementation base for locking was switched over from direct usage of POSIX primitives to the portable wrappers available in the C++ standard library. All usages have been reviewed and modernised to prefer λ-functions where possible. With this series of changes, the old threadpool implementation and a lot of further low-level support facilities are not used any more and can be dismantled. Due to the integration efforts spurred by the »Playback Vertical Slice«, several questions of architecture could be decided over the last months. The design of the Scheduler and Engine turned out different than previously anticipated; notably the Scheduler now covers a wider array of functionality, including some asynchronous messaging. This has ramifications for the organisation of work tasks and threads, and leads to a more deterministic memory management. Resource management will be done on a higher level, partially superseding some of the concepts from the early phase of the Lumiera project. |
