2020-02-20Restructure thread pool block processorDavid Oberhollenzer
Implement the io-queue based design as outline in doc/parallelism.txt Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-16block processor: merge rest of fileapi.c into common.cDavid Oberhollenzer

2020-02-16Replace crc32 with xxhash32David Oberhollenzer
On the one hand, benchmarking and profiling determined xxhash32 to be faster than the zlib implementation of crc32, on the other hand profiling determined that crc32 computation contributed signifficantly to the overall runtime. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2020-02-16block processor: move sparse block detection into worker threadDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-15Move block block accounting to the other end of the block pipelineDavid Oberhollenzer
This commit moves all of the fragment/block accounting in the block processor over to the writing end of the pipeline. In order to do this, the sparse blocks are allowed to bubble through the pipeline. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-15Cleanup: block processor: move init/cleanup functions into implemenationsDavid 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.

2020-02-12Clenaup: remove useage of sqfs_block_t from block writerDavid Oberhollenzer
The sqfs_block_t structure has been written for the block processor and exposes way too many internals. This commit removes its usage from the block writer, cutting it down to the bare essentials, so the structure can be removed from the public API later on. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-10Cleanup: remove block hooks entirely from block processorDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-10Cleanup: remove the fragment store/discard and block discard hooksDavid Oberhollenzer
There is no obvious non-footgun use for those other than tallying statistics, which is now done by the data structures themselves. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-10Add run time statistics to the block writer and processorDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-09block processor: merge left overs of block.c/fragment.c into common.cDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-09Move block writer and fragment table management out of block processorDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-01-31Split the block writing/deduplication away from the block processorDavid Oberhollenzer
This commit moves the entire block writing and deduplication of data blocks over to a different data type named "block writer". For simplicity, the interfaces of the block processor are left as is and are turned into warppers. Likewise, most of the code in the block writer is just verbatim from the block processor, to be cleaned up in subsequent commits.

2020-01-29Rename sqfs_data_writer_t back to sqfs_block_processor_tDavid Oberhollenzer
