2021-03-06Add a copy function to the rb-tree implementationDavid Oberhollenzer
If we use the rb-tree in libsquashfs objects, we need to be able top copy an entire tree as part of the object. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2021-03-05Remove lz4 & zstd from corpus testDavid Oberhollenzer
Relying on the output of a compressor to exactely match an expected output is already not really a great idea, but for gzip, xz and lzo it has worked remarkably well so far. Perhaps because those are rather old and don't have much active development going on besides bug fixing. On the other hand, lz4 and zstd which are much younger seem to have more development going on and keep breaking between versions. This commit removes the zstd & lz4 corpus tests.

2021-02-19fstree_from_file: Implement basic file globbingDavid Oberhollenzer
The base path is passed to the fstree_from_file function and in turn to the individual callbacks. The line parsing function is modified to allow '*' as mode, uid and gid for specifically marked callbacks. A glob callback is added that internally uses the fstree_from_dir scanning functions in combination with a filter callback. Directory scanning flags are parsed from the extra arguments before interpreting it as a path fragment. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2020-12-29Fix normalization of slashes in filenamesDavid Oberhollenzer
All paths were canonicalized internally, which includes filtering sequences of slashes and converting backslashes to slashes. Furthermore, when unpacking files, filenames are sanity checked and rejected if they contain forward OR backward slashes. This is a problem on Unix-like systems, where files containing backslashes are a legitimate use case (*cough* SystemD *cough*). This patch removes the backslash conversion from the canonicalization and modifies the sanity check to reject backslashes only on Windows.

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).

2020-05-21Fix: zstd: actually set the compression level from the optionsDavid Oberhollenzer
In the zstd compressor, the compression level from the configuration structure wasn't used at all. Instead, the zstd compressor was told to use level 0 and compressor options with that parameter were written to disk. This commit makes sure the level parameter is propperly initialized.

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.

2020-04-17Remove some configure time sizeof checksDavid Oberhollenzer
In libtar, the sizeof time_t checked when trying to store a time value. It is pointless using the preprocessor here, as we can simply do an if (sizeof(time_t) < ...) check and the compiler will take care optimizing away one or the other branch. After changing the libtar check and the corresponding unit tests, the sizeof check can be removed from configure.ac, along with other unused sizeof checks.

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.

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.
