2023-08-10	Refactor: rename dir_iterator_t to sqfs_dir_iterator_t	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-08-10	tar2sqfs: Add option to exclude files	Richard Weinberger
	Using --exclude or -E it is now possible to exclude files from the input tar stream. The options can be used multiple times. Signed-off-by: Richard Weinberger <richard@nod.at>
2023-07-10	Move sqfs_dir_entry_t code from libio into libsquashfs	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-07-03	Refactor: rename dir_entry_t to sqfs_dir_entry_t	David Oberhollenzer
	Exact operation performed: git ls-files -z \| \ xargs -0 sed -i -e 's/dir_entry_t/sqfs_dir_entry_t/g Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-15	Fix null pointer dereference in tar sqfs_istream_t implementation	David Oberhollenzer
	When dropping the parent iterator, update the state _first_. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-15	Overhaul sqfs_istream_t/sqfs_ostream_t error handling	David 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.

2023-06-15	Move sqfs_istream_t & sqfs_ostream_t into libsquashfs	David 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>
2023-06-15	Mass rename istream_t/ostream_t with sqfs_ prefix	David Oberhollenzer
	istream_t becomes sqfs_istream_t and ostream_t becomes sqfs_ostream_t Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-15	libio: remove single line wrapper functions	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-11	libio: move istream buffer logic into interall callbacks	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-11	libio: remove precache from istream_advance_buffer	David Oberhollenzer
	Since the user has to call istream_get_buffered_data afterwards anyway, we can do the precache lazily. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-10	libio: add desired read size to istream_get_buffered_data	David Oberhollenzer
	This properly maps to all of our use cases and makes istream_precache obsolete. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-09	libtar: overhaul buffer management in istream_t wrapper	David Oberhollenzer
	As soon as we no longer have any data to read, unlock/drop the parent iterator_t object. Also, make sure we get the buffer count right, not all data might have been consumed yet when precache is called. Remove the precache/read loop in the non-sparse case, we have already established that there is data available. If it is insufficient, the user will simply call precache again once it's used up, which istream_get_buffered_data forwards to a precache call in the underlying stream.

2023-06-09	libio: remove eof flag from istream_t interface	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-09	libio: eliminate direct access of the interal buffer	David Oberhollenzer
	Instead, go through helper functions, which in a next step can be moved inside the implementation. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-08	Move tar compressor auto wrapping code from tar2sqfs into libtar	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-05	Move dir_entry_xattr_t from libio to libsquashfs	David 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>
2023-06-05	libio: remove buffer_offset from istream_t	David 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>
2023-06-04	libio: Move istream_t precache logic into backend implementation	David Oberhollenzer
	The end goal is to remove direct buffer access from the istream_t interfaces and make that opaque. For the tar implementation, this already safes us needless buffer copying, as we essentially allow the user to read-through from the underlying stream. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-06-01	libio: split dir_entry_t from dir_iterator_t, add create helper	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-05-22	libtar: add a dir_iterator_t implementation for tar files	David 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>
