2020-02-22	Cleanup block processor: Merge destructors for Windows & pthreads	David Oberhollenzer
	Since the merged destructor checks if the objects it destroys were actually initialized, the pthread implementation can also replace its error path cleanup with simply calling the destructor. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-22	Add a seperate sqfs_block_processor_sync function	David Oberhollenzer
	This function waits for all pending blocks to be written to disk, but doesn't flush the fragment block, so processing can continue afterwards as if nothing happened. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-20	Thread pool block processor: Cleanup after restructuring	David Oberhollenzer
	- Merge duplicated code from append_to_work_queue and sqfs_block_processor_finish Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-20	Restructure thread pool block processor	David Oberhollenzer
	Implement the io-queue based design as outline in doc/parallelism.txt Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-18	Simplify the thread pool block processor somewhat	David Oberhollenzer
	- Split the worker function up into smaller functions that are a little more readable. - Only dequeue one block at a time. Makes the dequeueing a lot more readable and understandable. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-16	block processor: move the internals to the respective implementations	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-16	Move all the queue-waiting logic to the thread pool implemenation	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-15	Cleanup: block processor: move init/cleanup functions into implemenations	David Oberhollenzer
	Again, the generic init/cleanup functions do way too many things that are specific to the thread pool implementation. Thanks to the splitting up of the block processor, they also have become quite trivial. This commit moves those functions into their respective implementations, allowing even further simplificiation.

2020-02-15	Cleanup: block processor: move finish function back into implementations	David Oberhollenzer
	The "generic" version actually uses specific internals of the thread pool implementation. Move it back into the thread pool based implementation and simplify the serial processor. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-15	Cleanup: block processor: remove test_and_set_status	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-15	Cleanup: block processor: remove delayed thread notification	David Oberhollenzer
	Under the assumption that block processing is CPU bound and not I/O bound, this is entirely useless. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-12	Implement a more explicit object system	David Oberhollenzer
	Make every dynamically allocated, opaque data structure inherit from a common sqfs_object_t structure with common entry points (e.g. destroy). This removes tons of public API functions and replaces them with a simple sqfs_destroy instead. If semantics of the (until now implicit) object system need to be extended, it can be much more conveniantely done this way. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-09	Move block writer and fragment table management out of block processor	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-01-29	Rename sqfs_data_writer_t back to sqfs_block_processor_t	David Oberhollenzer
