2019-08-19Fix packer statisticsDavid Oberhollenzer
Needs regenerating of the file list that was ripped up and rearranged during file packing. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-19Fix file list generation: break any pre-existing connectionDavid Oberhollenzer
If the linked list pointer was already used before, break up the connection so we don't risk running into a loop or something when regenerating the list. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-19Make using pthread optionalDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-19Fix chmod of symlinks in restore_fstreeDavid Oberhollenzer
We can't change the mod of symlinks and hence AT_SYMLINK_NOFOLLOW is not supported by chmod(2 -> RTFM!). The solution is to not use that flag and simply skip symlinks. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-19Fix directory traversal in update_tree_attribsDavid Oberhollenzer
Do not try to change the nameless root node which is mapped to the output directory. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-19Minor improvements for parallel block processorDavid Oberhollenzer
- 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 <david.oberhollenzer@sigma-star.at>

Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-18Replace update_crc32 helper function with crc32 from zlibDavid Oberhollenzer
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 <david.oberhollenzer@sigma-star.at>
2019-08-18cleanup: internalize deduplication list in data_writerDavid Oberhollenzer
This change removes the need for passing a list of files around for deduplication. Also the deduplication code no longer needs to worry about order, since the file being deduplicated is only added after deduplication is done. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-18Add pthread based, parallel block processor implementationDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-18Add block processor data structureDavid Oberhollenzer
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 <david.oberhollenzer@sigma-star.at>
2019-08-16Add deep-copy function to compressor interfaceDavid Oberhollenzer

2019-08-11cleanup: zero-initialize gensquashfs options with memsetDavid Oberhollenzer
Manual initialization is not only verbose, it actually caused a bug in a past version. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-11Fix wrong argument type for gensquashfs --keep-timeDavid Oberhollenzer
Copy paste mistake: the propper type should be no_argument as it is only a simple flag and doesn't take extra arguments. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-08-11Split gensquashfs help string because it got too longDavid Oberhollenzer
There is an upper limit of characters in a string literal that it managed to cross. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-08-07Extend filesystem diff utility to work on squashfs imagesDavid Oberhollenzer
Since it already works on an fstree_t instance (constructed from the input paths), and we now have a handy sqfs_reader_t, it is quite simple to extend. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
