2021-04-08	Fix: libsquashfs: add sqfs_free() function	David Oberhollenzer
	On systems like Windows, the dynamic library and applications can easily end up being linked against different runtime libraries, so applications cannot be expected to be able to free() any malloc'd pointer that the library returns. This commit adds an sqfs_free function so the application can pass pointers back to the library to call the correct free() implementation.

2020-06-14	extras: Pass flags argument to fix build	Matt Turner
	Missed in commit 259a98985b4f (Add flags to functions that might logically be expanded in the future) Signed-off-by: Matt Turner <mattst88@gmail.com>
2020-03-22	Do not try to read back the compressor options	David Oberhollenzer
	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.

2020-03-05	Get rid of sqfs_compressor_exists	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-03-05	Change the signature of sqfs_compressor_create to return an error code	David Oberhollenzer
	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.

2020-02-28	Minor fix in file browser demo	David Oberhollenzer
	- Make sure to release the inode returne by the dir reader - Check the path resolution return code in change_directory Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-02-23	Unify the payload counters in the sqfs_inode_generic_t	David Oberhollenzer
	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 <david.oberhollenzer@sigma-star.at>
2020-02-12	Implement a more explicit object system	David Oberhollenzer
	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 <david.oberhollenzer@sigma-star.at>
2020-01-20	Add a flag field to the id table create function	David Oberhollenzer
	Just to be safe in case there needs to be an extension in the future. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-01-20	An attempt at cleaning sqfsbrowse a little and adding explanations	David Oberhollenzer
	Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-01-20	Add a "cat" command to sqfsbrowse that uses the data reader	David Oberhollenzer

2020-01-19	Cleanup: remove the payload pointers from sqfs_inode_generic_t	David Oberhollenzer
	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 <david.oberhollenzer@sigma-star.at>
