release 5.6.4 requires a full wipe of database

[ereshetova]

After upgrading to version 5.6.4 from the previous one, when a tool tries to update the database, this happens:

process_node(): attempt to write to a readonly database
process_node(): attempt to write to a readonly database
process_node(): attempt to write to a readonly database
process_node(): attempt to write to a readonly database
process_node(): attempt to write to a readonly database
....

many times

The issue is not visible if the database if fully wiped and downloaded from fresh by the 5.6.4 version.

Apologies I wasn't aware of that. I'd already purged my old files in trying to fix the issue of NVD URI

^ Wrong button pushed. So yeah I'll go back to the old cve-check-tool and find a way to detect the break, and implement a workaround if possible.

I don't know how much effort this is worth, since I guess we can just wipe out the old db from the builders, but wanted to report it here since other people might see the same issue.

OK so the new tool is going to correct the faults of the old - and I've begun this with a migration scheme:

Note there are big differences between the old DB and the new DB - hence the format bump.
186MB vs 26MB

Legacy database has the suffix: nvd.db
New format now has: nvd-1.db

Also we should keep this issue open until the new tool is released, just so others are aware, like you said :)
