Here is attached the latest working version of reiserfs handling.
What it does :
- Recognises the partition type
- Read the partition label (needs confirmation of the label position)
- List directory content (see limitations)
- Read file content (see limitations)
Limitations :
- Item (file & dir) size limited to one indirection block. Readable size is a
bit less than number_of_contiguous_indirect_pointers * block_size, which
means at most 16MB on a 8192 bytes/block reiserfs, 4MB on a 4096 bytes/block,
etc.
- No symlink support : although the symlinks can be read, they are read as a
text file containing a path, nothing more.
- No journal playback
- Alpha version : will potentially leak memory, be slow, not suitable for your
needs, not tested with all kinds of reiserfs options & versions... Play
with^W^WUse it at your own risks - risks which should be limited to wasting
time because no write is ever done to the partition, of course.
Ah, and it's not always 80-columns wordwrapped, other than that the coding
style should be respected. This will be fixed in the final version.
