Fix: Move fragment consolidation back to block processor serial part

2021-01-19T09:30:20+00:00

Keeping a list of fragments stored away in the current fragment block and consolidating them in the thread pool takes them out of circulation. If we have a lot of tiny fragments, this can lead to a situation where all the limit is reached, but we cannot do anything, because we are waiting for a block to complete, but they are all attached to the current fragment block and the queue is empty.

Fix block processor single block with don't fragment flag bug

2020-08-11T22:25:34+00:00

This commit fixes a bug where the block processor state machine would not add the "last block" flag if there is only one not entirely filled block and the "don't fragment" flag is set. If the flag isn't set, the inode start block position is not updated and points to the beginning of the image instead. Signed-off-by: David Oberhollenzer

Move the fragment deduplication hash table back into the block processor

2020-06-07T00:44:10+00:00

Fragment deduplication really doesn't belong into the public API of the fragment table. Signed-off-by: David Oberhollenzer

Block processor: allow operation without a fragment table

2020-05-29T17:56:59+00:00

This commit modifies the block processor to support operating without a fragment table. If that is the case, fragment deduplication is essentially disabled and fragment blocks aren't indexed anymore. Signed-off-by: David Oberhollenzer

Block processor: Add a raw block submission function

2020-05-29T17:56:59+00:00

This function allows submission of raw blocks to the block processor, completely bypassing the file API. Signed-off-by: David Oberhollenzer
