Ok, the good news is that this seems to be the problem.
unfortunantly the skiplist recovery tool is not working.
# ./skiplist.py dlang.seen.bak >dlang.seen.txt
Traceback (most recent call last):
File "./skiplist.py", line 172, in <module>
values, keys = getkeys(fp)
File "./skiplist.py", line 152, in getkeys
spointer = unpack('>I', str_p)[0]
struct.error: unpack requires a string argument of length 4
# file dlang.seen.bak
dlang.seen.bak: Cyrus skiplist DB
I tried enabling debug mode in skiplist.py and I'm not seeing anything
different. This confuses me. I'm not that familiar with python, but as I read
the code, get_header() should be writing a bunch of stuff before it gets to the
getkeys() section that failing.
