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.

2020-03-18Set a minimal libzstd version in autoconf scriptDavid Oberhollenzer
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.

2019-11-15Fix build on BSD systemsAlyssa Ross
I tested FreeBSD, DragonflyBSD, NetBSD and OpenBSD and the endian macros weren't necessary (and in fact caused errors) on all of them. Because OpenBSD ships with an ancient GCC that doesn't support the checked addition/multiplication builtins, the build there would fail unless built with CC=cc or CC=clang. I changed configure.ac to prefer cc over gcc, so that the distribution's compiler preference is respected. (The default is [gcc cc]). I had to move AC_PROG_CC above LT_INIT because otherwise LT_INIT would run AC_PROG_CC first, and we wouldn't have a chance to use non-default parameters.

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.
