2022-11-04Only use available CPUsWessel Dankers
Not all CPUs may be available for the current process. Some CPUs may be offline, others may not be included in the process affinity mask. In such cases too many threads will be created, which will then compete unnecessarily for CPU time. Use sched_getaffinity() to determine the correct number of threads to create.
2022-06-03Roll autoconf version back to a less ambitious oneDavid Oberhollenzer
Autoconf 2.69 was released in 2012. After that, 2.70 was released in December 2020 and 2.71 in January 2021. According to repology, only very few distros ship 2.7x, most still being on 2.69. This includes the last Ubuntu LTS release, which is used as goto container distro in our automated testing and analysis setup. Version 2.69 should cover most distros, except some outliers like CentOS 6 or Maemo Fremantle (*cough* Nokia N900). Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2022-04-23configure: Abort/fail if there is not compressor libraryDavid Oberhollenzer
Implement a check that verifies that we have at least a single SquashFS block compressor available and aborst the build if none was found. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2022-04-10Remove builtin copy of zlibDavid Oberhollenzer
On GNU/Linux, *BSD or MacOS we can simply use the system default library. The copy was primarily only there for the Windows build. The build script for Windows has now been adapted to download and compile a shared library from a tarball. This removes a huge chunk of code from the git tree as well as the release tarballs. Additionally it gets rid of iffy things like removing the Zlib copyright/version strings, so the libsquashfs DLL doesn't export it.

2021-03-07Optionally use a pool allocator for rb-tree nodesDavid Oberhollenzer
This commit restructures the rbtree code to optionally use a pool allocator for the nodes. The option is made depenend on the presence of a pre-processor flag. To the configure script is added an option to enable/disable the use of custom allocators. It makes sense to still allow the malloc/free based routes for better ASAN based instrumentation.

2021-01-23Bump version numbers & changelog after 1.0.4 releaseDavid Oberhollenzer
This commit imports the changes to the CHANGELOG.md in the backports branch after the 1.0.4 release and updates the package scripts to point to the new release. In addition, the version numbers in configure.ac are update to more closeley reflect reality, i.e. set the current so version and set the package version to 1.1.0 which will be the next release from master. The unreleased changes in master are also added to the CHANGELOG.md. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-12-19Fix: replace the pkg-config check for bzip2 with a manual checkDavid Oberhollenzer
The upstream package for bzip2 does not provide a pkg-config file. Some GNU/Linux distributions (e.g. Fedora) have added one, but others like Debian have not. Since Debian and its deriatives are much more wide spread, this makes the existance of a pkg-config file the exception, rather than the norm. This commit replaces the pkg-config based check in configure.ac with a manual check based on AC_CHECK_LIB and AC_CHECK_HEADERS, similar to what is already done for lzo2.

2020-09-17Add a check whether libzstd supports stream compressionDavid Oberhollenzer
Streaming compression was added fairly recently to zstd (and then the API was changed a few times). Rather than rely on libzstd versioning macros, this commit adds an m4 script to test at configure time if the enums/functions we need are available by trying to compile a small sample.

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.

Version 1.3.1 is the first one which has fixed error codes exposed through the public API, which are used in the zstd compressor to determine whether compression *actually* failed or if the destination buffer was too small. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

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.
