2020-09-03Cleanup: reduce tar test cases to a few generic C filesDavid Oberhollenzer
This commit removes the existing tar test cases that simply call the generic test case function with several different paths with generic test case source files that are parameneterized via the pro-processor. For each tar archive, a separate test case is generated. On the one hand, this reduces the test source code to practically nothing. On the other hand, a test binary is generated for every distinct test case, instead of one per group and we get more detailed insights if something goes wrong.

2020-09-03Cleanup copy & paste mess in the tar parser test casesDavid Oberhollenzer
Many of the patterns tested are very repetetive. This commit moves the two common test cases out into helper functions and uses them for the test cases. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-09-02Fix nonexistant gnu tar sparse format 1.0 supportDavid Oberhollenzer
Contrary to previous claims, support for the GNU tar sparse format 1.0 was missing entirely (the newest of their 3 different sparse mapping formats). This oversight wasn't caught, because the unit test was compiling the wrong source file and tar2sqfs had no problem processing the test file because it is still a valid POSIX-ish tar archive (but the sparse part was missing and the mapping embedded in the file).

2020-05-03Add a simple test script for the gensquashfs packdir + allroot use caseDavid Oberhollenzer
Since this is a fairly common use case, it deserves a simple test case to check out that e.g. option processing hasn't been botched up (again). As input directory, the licenses directory is used as it contains no intermediate build output and should change fairly infrequently. The test is enabled irregardless of the corpora-test option.

2020-04-17tests: improve diagnostics output & make "release builds" workDavid Oberhollenzer
This commit adds a few macros and helper functions for the unit test programs. Those are used instead of asserts to provide more fine grained diagnostics on the one hand and on the other hand because they also work if NDEBUG is defined, unlike asserts that get eliminated in that case. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-03-18Add a test case for xxhash32David Oberhollenzer
Technically the code was imported by a third party library, but some modifications have been made. This commit adds a simple test case with some test vectors and expected results that have to match. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2020-02-21Cleanup: move utilities back out of libsquashfsDavid Oberhollenzer
This commit removes the allocation helpers and string table functions out of libsquashfs back into a "libutil.a". The problem of libsquashfs exporting stuff that it shouldn't is resolved by retaining the internal attributes and directly adding the source to libsquashfs instead of trying to somehow link against libutil.la.

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>

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>

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.
