2023-06-17Move data writer ostream into libsquashfsDavid Oberhollenzer
It is mainly a very thin wrapper on top of the block processor so far. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-15Overhaul sqfs_istream_t/sqfs_ostream_t error handlingDavid Oberhollenzer
Report an error number from the implementations, change the users to forward that error number (which also means libtar write header/link now returns an error code) and all subsequent binaries to use sqfs_perror() instead of relying on the function to print an error internally. Also, make sure to preserve errno/GetLastError() in the implementations and print out a stringified error in sqfs_perror() if the error code indicates an I/O error.

2023-06-15Move sqfs_istream_t & sqfs_ostream_t into libsquashfsDavid Oberhollenzer
For now, only the interfaces and helper functions are moved, the concrete implementations remain in libio. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-15Mass rename istream_t/ostream_t with sqfs_ prefixDavid Oberhollenzer
istream_t becomes sqfs_istream_t and ostream_t becomes sqfs_ostream_t Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-15libio: remove single line wrapper functionsDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-08Move tar compressor auto wrapping code from tar2sqfs into libtarDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-05libsqfs: Add an xattr writer function to add a combined key-value structDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-05Move dir_entry_xattr_t from libio to libsquashfsDavid Oberhollenzer
The structure and functions are renamed to sqfs_xattr_* instead, an additional helper is added to accept an encoded xattr. Documentation and unit test are added as well. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-05libio: remove buffer_offset from istream_tDavid Oberhollenzer
Instead, make the buffer const, let the user adjust the pointer and size. The offset can then be inferred in precache. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-04libio: move splice function from ostream to istreamDavid Oberhollenzer
It touches internals of the istream, particularly the buffer, but not of the ostream. It really belongs to istream_t. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-05-30libfstree: accept dir_entry_t instead of path and struct statDavid Oberhollenzer
Because the dir_entry_t also has a flag for had links, the regular node and hard-link node interface can be unified. This simplifies the users of libfstree (gensquashfs, tar2sqfs) since we can simply hose the entries from an iterator directly into the tree. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-05-22libtar: add a dir_iterator_t implementation for tar filesDavid Oberhollenzer
The existing istream_t wrapper is mered into this one as well, we can open the files via the iterators open_file_ro function. Unit tests and tar2sqfs are modified accordingly. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-05-16libtar: replace tar_xattr_t with dir_entry_xattr_t structDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-04-19libfstree: Remove external file_info_t declarationDavid Oberhollenzer

2023-04-02Move fstree CLI code to libcommonDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-02-08libtar: remove need for skip_padding functionDavid Oberhollenzer
In the istream implementation, automatically skip the padding when we reach end-of-file. Also skip file AND padding when we destroy the object. Replace the remaining instances with a simple istream_skip instead and remove the wrapper from libtar. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-02-08tar2sqfs: Use tar istream spliceDavid Oberhollenzer
