2023-01-19Simplify cleanup on errorDavid Oberhollenzer
The drop/destroy functions support passing in a NULL pointer. 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.

2020-05-26sqfsdiff: extract compressor options, but don't fail on errorDavid Oberhollenzer
This commit modifies sqfsdiff to extract the compressor options from the squashfs image and store them in a compressor configuration if possible. The failure path is modified to *not* burst into flames on error, because those options are not required by any compressor to read data from the disk and pretty much every vendor modifed SquashFS has messed with those to the point that they cannot be propperly decoded (or the flag is set and there are no options).

2020-04-27Cleanup directory structure of the binary programsDavid Oberhollenzer
Instead of having the binary programs in randomly named subdirectories, move all of them to a "bin" subdirectory, similar to the utility libraries that have subdirectories within "lib" and give the subdirectories the propper names (e.g. have gensquashfs source in a directory *actually* named "gensquashfs").
