2022-07-08Move sqfs_tree_node_get_path to libsquashfsDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2022-07-08Cleanup: move inode_stat to sqfs2tarDavid Oberhollenzer
After trying removing many instances of `struct stat`, there is only one user of inode_stat left, so move the function there. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2022-07-08Cleanup: split libtar header, move to sub directoryDavid Oberhollenzer
Some of the on-disk format internals are moved to a separate header and some of the stuff from internal.h is moved to that format header. C++ guards are added in addtion. Everything PAX related is moved to pax_header.c, some internal functions are marked as static. 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.

2021-04-08Fix: libsquashfs: add sqfs_free() functionDavid Oberhollenzer
On systems like Windows, the dynamic library and applications can easily end up being linked against different runtime libraries, so applications cannot be expected to be able to free() any malloc'd pointer that the library returns. This commit adds an sqfs_free function so the application can pass pointers back to the library to call the correct free() implementation.

2021-02-10Always use the correct data type for realloc return valueDavid Oberhollenzer
This commit mainly serves the static analysis tooling. 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.

2020-09-17Fix: add missing compiler/linker flagsDavid Oberhollenzer
If tar2sqfs and sqfs2tar want to use comperssion via libfstream, they need to link against the compressor libraries. Also, libfstream may need the apropriate cflags to access the headers on some platforms. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-09-16Add bzip2 stream compression supportDavid Oberhollenzer

2020-09-16Remodel file extraction tools to use libfstreamDavid Oberhollenzer
This commit rewrites the libtar write paths to use libfstream insead of a FILE pointer. Also, the libcommon file extraction function is remodeled to use libfstream. In accordance, rdsquashfs, sqfs2tar and sqfsdiff have some minor adjustments made to work with the ported libtar and libcommon. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2020-05-30sqfs2tar: Move hard link detection to tree-repacking codeDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-05-30Cleanup: sqfs2tar: break up and simplify the repacking codeDavid Oberhollenzer
- Move the xattr extraction and repacking to xattr.c - Don't on-the-fly delete the tar xattr list, use the function from libtar.a - Split minor tasks into static helper functions - creating a libtar xattr struct from libsqfs xattr data - finding a hard link entry from current path and inode number Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-05-30Cleanup: Reorganize structure of Automake filesDavid Oberhollenzer
- Split up the huge file in bin/ into one small file per sub directory - Remove the stub in doc/ Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-05-30Cleanup: move man pages to the respective program source directoriesDavid Oberhollenzer

2020-05-30Cleanup: try to split sqfs2tar.c in a reasonable wayDavid Oberhollenzer
This comit breaks sqfs2tar into multiple files: - options.c contains the command line argument processing - write_tree.c contains the code for generating the actual tar archive - sqfs2tar.c contains what is left - A header is added for glueing it all together. No actual code is changed. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
