Absolute db paths cause sqlite3.OperationalError

[jayvdb]

from_uri removes any leading / in the path given, so /home/foo/blah.db becomes home/foo/blah.db which cant be opened because it is a relative path and the directories are missing.

You can see my horrible workaround at https://github.com/jayvdb/dns-cache/blob/83a3df0b9ee43339d1f928696eef1558c881997b/dns_cache/stash.py#L41

It will very likely break if this is fixed, but that is OK as it is still a new/alpha piece of software and I am not using the stash driver at the moment.

There are a few other interesting issues faced in the tests found in https://github.com/jayvdb/dns-cache/blob/93a4ae5722d3a5b78fe69f13939ea77544e70011/tests/test_persistence.py which may be of interest to you, and I will work on as I can find time.
