[freeipdb-hackers] ipdbDoctor

[Anthony DeRobertis]

Just wanted to let everyone know that I'm writing a new database 
consistency checker / repairer for freeipdb. I'm doing this because 
mine seems to have become quite inconsistent, and gone into 
self-destruct mode...

It already finds many errors that the check script doesn't even think 
about. A partial list of what I'm checking for:

        o block is on a bit boundry
        o bits are in range (for the given address type)
        o children agree with parent. (childl/r vs. parent col)
        o check for blocks that appear to be ipv6 in ipv4 region or vice versa
        o check to make sure the region a block is in exists
        o check that parents have 0 or 2 children
        o check that children have appropriate # of bits
        o check that children have appropriate blocks
        o check that no node is the child of more than 1 parent
        o check that no node is the child of 0 parents
Any suggestions for more?

I'll be contributing the (rather long) perl script. Currently, its 
quite slow (makes thousands of db queries...) but that can be fixed.

Annoying. Third attempt to send using the right email address. 
Double-arg!
