Do not try to read back the compressor options

2020-03-22T22:30:28+00:00

None of the currently implemented compressors do anything with that data. They are all at the mercy of the data actually in the image. This commit removes the code from sqfs2tar and rdsquashfs that decodes the options, which also has the side effect of increasing compatibillity with some non-confirming images.

Change the signature of sqfs_compressor_create to return an error code

2020-03-05T21:41:04+00:00

Make sure the function has a way of telling the caller *why* it failed. This way, the function can convey whether it had an internal error, an allocation failure, whether the arguments are totaly nonsensical, or simply that the compressor *or specific configuration* is not supported.

Unify the payload counters in the sqfs_inode_generic_t

2020-02-23T03:02:49+00:00

Instead of having seperate counters for blocks, dir index bytes and having to fiddle out the link target size, simply use a single value that stores the number of payload bytes used. A seperate "payload bytes available" is used for dynamically growing inodes during processing. Signed-off-by: David Oberhollenzer

Implement a more explicit object system

2020-02-12T01:26:24+00:00

Make every dynamically allocated, opaque data structure inherit from a common sqfs_object_t structure with common entry points (e.g. destroy). This removes tons of public API functions and replaces them with a simple sqfs_destroy instead. If semantics of the (until now implicit) object system need to be extended, it can be much more conveniantely done this way. Signed-off-by: David Oberhollenzer

Cleanup: remove the payload pointers from sqfs_inode_generic_t

2020-01-19T19:05:13+00:00

There are 3 types of extra payload: - Directory index - File block sizes - Symlink target This commit removes the type specific pointers and modifies the code to use the payload area directly. To simplify the file block case and mitigate alignment issues, the type of the extra field is changed to sqfs_u32. For symlink target, the extra field can simply be cast to a character pointer (it had to be cast anyway for most uses). For block sizes, probably the most common usecase, it can be used as is. For directory indices, there is a helper function anyway. Signed-off-by: David Oberhollenzer
