"""Migrate the usage data from the old bundled Transit Relay database.
|
||
|
|
|
||
|
|
The magic-wormhole package used to include both servers (Rendezvous and
|
||
|
|
Transit). "wormhole server" started both of these, and used the
|
||
|
|
"relay.sqlite" database to store both immediate server state and long-term
|
||
|
|
usage data.
|
||
|
|
|
||
|
|
These were split out to their own packages: version 0.11 omitted the Transit
|
||
|
|
Relay in favor of the new "magic-wormhole-transit-relay" distribution.
|
||
|
|
|
||
|
|
This script reads the long-term Transit usage data from the pre-0.11
|
||
|
|
wormhole-server relay.sqlite, and copies it into a new "usage.sqlite"
|
||
|
|
database in the current directory.
|
||
|
|
|
||
|
|
It will refuse to touch an existing "usage.sqlite" file.
|
||
|
|
|
||
|
|
The resuting "usage.sqlite" should be passed into --usage-db=, e.g. "twist
|
||
|
|
transitrelay --usage=.../PATH/TO/usage.sqlite".
