2019-09-25	More refactoring of the block processor	David Oberhollenzer
	Basically just moving functions around and renaming things. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-25	Refactor out common code of the block processors	David Oberhollenzer
	Code that already is shared between the pthread and the serial processor as well as code that can be re-used by other threading API implementations. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-24	Do the fragment checksumming in the workter thread	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-24	Move entire fragment processing from data writer to block processor	David Oberhollenzer
	So far, this is mostly a direct port from the block processor. The actual fragment checksumming is not done through the thread pool. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-24	Breake some of the helper functions out of process_block.c	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-24	Cleanup pthread based block processing code	David Oberhollenzer
	Break convoluted, long functions up into smaller ones where the control flow (especially locking and signalling) is more easily readable and remove some copy and paste clean up code. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-24	Process completed blocks one-by-one	David Oberhollenzer
	This commit makes sure the block processor enqueue function dequeues at most a single block which it dispatches. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-23	Cleanup block processor error handling	David Oberhollenzer
	If an error happpens, immediately stop everything and report only the first error that happened. This also fixes a memory leak in the error paths of the serial and pthread based block processors. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-23	Cleanup block processor flag handling	David Oberhollenzer
	First, remove the "Don't checksum" flag, fragment blocks also need to be checksumed and are also subject to deduplication. For sentinel blocks, instead check if the size is zero. Second, cleanly seperate the user settable flags from the non-user settable flags and reject any block that has non-user settable or unknown flags set.

2019-09-23	Move the bulk of the work from the data writer to the block processor	David Oberhollenzer
	Instead of calling a callback, the block processor now takes care of writing the data blocks to the file in the correct order, keeping track of fragment blocks and deduplicating blocks. Some cleanup work remains to be done and the statistics have to be repaired (yet again). Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-21	Merge some of serial & pthread block processor code paths/declarations	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-13	Make block process helper function internal	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-12	Cleanup: move block processor code to sub directory	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
