2023-02-21libio: Add an xfrm stream wrapper testDavid Oberhollenzer
This basically re-uses the libxfrm pack/unpack tests, but runs the data through a stream wrapper. When de-compressing, we have a ridiculously tiny input buffer, to force the wrapper to snort up the data in several attempts until the it can decompress something. We read the data byte-by-byte to force the wraper to internally cache the uncompressed data and spoon feed it to us. It has to be completely transparent to us that it internaly decompresses and also reads transparently across concatenated streams. When compressing, we only require that the output is smaller than the input and not equal to it. We also require the wrapper to flush the wrapped stream when it is flushed. We then test if the compressed data can be unpacked again. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-02-20Remove ostream_printfDavid Oberhollenzer
By cobbling together the xattr lines manually in libtar, the need (and thus the function itself) are removed. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2023-01-19Split stream compression out of libioDavid Oberhollenzer
Move it to a separate libxfrm library, where it can be independently tested as well. The bulk of the new code is also mainly test cases for the compressors. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-01-19Implement rudimentary reference counting for sqfs_object_tDavid Oberhollenzer
Implement grab/drop functions to increase/decrease reference count and destroy the object if the count drops to 0. Make sure that all objects that maintain internal references actually grab that reference, duplicate it in the copy function, drop it in the destroy handler.

2022-12-14Fix unix istream eof flagDavid Oberhollenzer
Propperly set the parent eof flag and not a local one that isn't accessed at all. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2022-08-23Cleanup gzip range clamping codeDavid Oberhollenzer
The zlib library uses a typedef'd uInt type for ranges which may be smaller than size_t. The complicated clamping to the uInt range is technically not needed, as the buffer size can grow at most to BUFSZ anyway, and it also confuses coverity.
