2019-12-15Add a test script that turns all test tarballs into SquashFS imagesDavid Oberhollenzer

2019-12-13Add a simplistic integration and regression testDavid Oberhollenzer
This test basically consists of the Canterbury Corpus which is turned into a SquashFS image using every supported compressor, with every supported block size, with and without tail end packing. The results MUST have an exact, given sha512sum. If that changes, it means either a regression in the output format, something broke or non-deterministic packing behaviour.

2019-11-25Cleanup: move overflow safe alloc code into libsquashfsDavid Oberhollenzer
There were only a hand full of instances outside libsquashfs that used the alloc code. In most cases, the thing allocated hat its size derived from something already in memory anyway, so it is safe to assume its size fits into a size_t. At the same time, the opencoded Windows path conversion functions are all unified into a single helper function. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-10-08Add a configure option to disable building the toolsDavid Oberhollenzer
If this option is used, only libsquashfs is built and installed, and the test cases for the other helper libraries are deactivated. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-10-07Improve ABI backward & forward compatibillityDavid Oberhollenzer
- Padd the compressor config union - 128 bytes aught to be enough for everyone, i.e. future compressors. - Insist that the padding space is initialized to 0. If a field gets added to an existing compressor, it can test for 0 as a sentinel value. - Add a size field to the hook structure, aka "the Microsoft way". - The explanation is in the comment. - Don't make the Microsoft mistake of checking for >=, insist on *exact* size match. Future users will need a fallback if their hooks are rejected. But at least they will be rejected instead of silently not being used. - Add an unsupported flag check to the dir tree reader. - Add a basic abi unit test that, for now, checks the size of the compressor config struct fields.

2019-09-01Move some application specific stuff out of libutilDavid Oberhollenzer
This commit does the following: - canonicalize_name is moved to libfstree - source_date_epoch is only used inside libfstree, so it's also moved over and can later be completely internalized - print_version is moved over to sqfshelper. Mainly so it doesn't end up in libsquashfs.so for no sane reason. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

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 <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.

2019-06-28Regroup tar format testsDavid Oberhollenzer
Instead of having test cases per feature with multiple vendors, pack the tests into test case per vendor with miltiple features. This should make errors easier to find, since the code many vendor extensions is closely related for all features. E.g. breaking pax header parser is will now trigger the pax test case and the others still work, vs all tests breaking because each feature test also tries to read the pax version.
