2020-11-07Cleanup: libcommon: try to split up some of the larger filesDavid Oberhollenzer
The sqsf_writer is moved to a separate header, as well as the compressor related stuff. The statistics function is moved into the writer code, as this is the only place that actually uses it. The writer code itself is split up into a hand full of file in their own subdirectory. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-09-29Update tar2sqfs/sqfs2tar documentationDavid Oberhollenzer
Modify the man pages and help texts to mention compression support, make the help option display a list of supported compressors. Also clarify the squashfs compressor list in the help text to state that the list shows block compressors supported for SquashFS compression.

2020-03-19Fix compressor availability check in libcommonDavid Oberhollenzer

2020-03-05Cleanup: Remove the E_ prefix from all libsquashfs enumeratorsDavid Oberhollenzer
Avoid namespace polution. Make sure all exportet symbols are prefixed with either sqfs_ or SQFS_. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-11-24Fix: Move LZO compressor from libsquashfs to libcommonDavid Oberhollenzer
The liblzo2 library is licensed under GPLv2, so it is not possible to distribute binaries of libsquashfs that link against liblzo2 under LGPL. This commit moves the LZO compressor implementation to libcommon, where this isn't a problem, since the tools themselves are licensed under GPLv3. It removes the ability of libsquashfs to read or generate LZO compressed SquashFS images, but the tools still can. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-10-07Rename libsqfshelper to libcommonDavid Oberhollenzer
That is IMO less confusing and express what it is (i.e. what it has become) more clearly, i.e. common code shared by the utilities. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
