Some simple search/replace cases for allocation

2019-08-23T00:09:51+00:00

This commit exchanges some malloc(x + y * z) patterns that can be found with a simple git grep and are obvious for the new wrappers. Signed-off-by: David Oberhollenzer

Minor improvements for parallel block processor

2019-08-19T09:08:25+00:00

- Fewer lock aquires in worker function - There is no point in locking/unlocking for inserting the completed block if we are going to lock again immediately in the next iteration -> Merge those two critical sections into one - Constant time queue insertion - Bypass queue entirely if there is nothing to do for a block Signed-off-by: David Oberhollenzer

Replace update_crc32 helper function with crc32 from zlib

2019-08-18T20:53:32+00:00

It is optimized to the maximum and if we already use zlib anyway, why not use zlib crc32? This also makes zlib a hard dependency which also means the whole "do we have a compressor" sanity check in the build system can be removed. Signed-off-by: David Oberhollenzer

Add block processor data structure

2019-08-18T20:44:39+00:00

The interface is designed for parallel, asynchronuous processing of data blocks with an I/O callback that handles the serialized result. The underlying implementation is currently still synchronuous. Signed-off-by: David Oberhollenzer

Replace reads in squashfs with positional reads

2019-07-25T12:20:48+00:00

In most cases, we know exactely where the data that we want to read is on disk, so instead of using read() on the squashfs (or lseek + read), the code can in many places be cleaned up to use the pread wrapper read_data_at instead. Signed-off-by: David Oberhollenzer

Include the reason ZSTD gave us for the error

Without it you're left guessing or using a debugger to figure out what's wrong. Signed-off-by: Matt Turner Signed-off-by: David Oberhollenzer
