Document SQUASHFS_LREG_TYPE, SQUASHFS_LDIR_TYPE

[probonopd]

I have written code that extracts squashfs. When trying to extract some (rare) files, I get:

TODO: Implement inode.base.inode_type 9
TODO: Implement inode.base.inode_type 8

According to squashfs_fs.h,

#define SQUASHFS_LDIR_TYPE      8
#define SQUASHFS_LREG_TYPE      9

Whatever that means.

What are ldir, lreg? Something to do with sparse and xattr?

Thanks for using squashfuse. The different inode types are pretty internal, which is why they're undocumented.

The different L types are just longer forms. They're used when there's extra data that's uncommon, so it's not worth storing in the usual case. Eg: xattrs, or files with lengths over 32 bits, etc.

Thanks @vasi

The question is what would I have to change in my code to get rid of the placeholders so that instead of printing out

TODO: Implement inode.base.inode_type 9
TODO: Implement inode.base.inode_type 8

it would actually work?

Probably just change your if statements to include the extra types:

} else if(inode.base.inode_type == SQUASHFS_REG_TYPE || inode.base.node_type == SQUASHFS_LREG_TYPE){

You might want to use a switch/case statement instead of an if, to make it easier to read.

Thanks, it is working now.
