Comment (by gracinet):
A quickfix is at
https://github.com/gracinet/buildbot/commit/c9289275452555f96db2aa1edd8e2824f34e85dc
Contrary to what the commit message says, the transactional behaviour with
the quickfix is suboptimal (the transaction is about several changeset,
one failed insert should not rollback the others).
A better version would be to check for prior existence and update or
insert accordingly, but I'll have to dig a bit further to know what this
is about really.
savepoints would be an option, but I'm not sure all RDMS provide them
(does SQLite ? ) IIRC, they're not even exposed in an abstract API by
psycopg2.
