2019-09-26Remove the create I/O block from sqfs_file_t functionDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-25Remove condensed sparse file handling from libsquashfsDavid Oberhollenzer
This only exists for tar2sqfs. Move the sparse file map to libtar and add the ability to do this into the stind sqfs_file_t abstraction, so it acts like a normal file but internally stitches the data together from the sparse implementation.

2019-09-15Move condensed-sparse-file handling to libsquashfsDavid Oberhollenzer
Add another helper function for getting a blocks from a condensed sparse file, then rewrite the data writer to use that instead, using an sqfs_file_t pointer instead of direct file i/o. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-15Move sparse_map_t to libsquashfs headers, rename it to sqfs_sparse_map_tDavid Oberhollenzer

2019-09-15Replace file descriptor IO in data_writer with sqfs_file_tDavid Oberhollenzer
First, this commit moves the create-blocks-from-fd function over to libsquashfs and ports it to work on an sqfs_file_t instead. Second, the function in the data_writer that reads from a file descriptor is adjusted to use an sqfs_file_t instead. Finally, the tools that use it have to be adjusted accordingly.

2019-09-09Change license of libsquashfs.soDavid Oberhollenzer
This this commit, the code that is compiled and linked to produce libsquashfs.so (and *only* libsquashfs.so) is released under the terms and conditions of the GNU Lesser General Public license, allowing 3rd party programs to dynamically link against it and still being able to release their programs under a license of their choosing. The libutil library is also relicensed, because it is statically linked into libsquashfs.so. This does not affect the command line programs that remain under the GPLv3. At the current time, the two libraries do not contain any 3rd party contributions and thus do not require anybodys consent other than mine to change the licensing terms (unlike e.g. libfstree.a). The libfstree.a and libsqfshelper.a utility libraries will also remain under the GPLv3 license. Going forward, some parts of libsqfshelper.a will be moved to libsquashfs.so. The parts absorbed by libsquashfs.so will then also have their licensing conditions changed *at that time*. For the public headers, this commit adds the full boiler-plate comment about the license, for the source files and internal headers, only the SPDX identifier is changed.

2019-09-08Replace direct file I/O with abstraction layerDavid Oberhollenzer
This should make it easier to use libsquashfs with custom setups that embedd a squashfs image inside something else. Also, it should make it easier to port to non unix-like platforms. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
