Description Randy Barlow 2013-02-08 16:00:53 UTC

We discovered recently that our RPM .spec file for the RPM plugins did not include the egg-info. This prevents the entry point system from functioning, which prevents the migration system from finding the RPM migrations.

We've discussed some possible solutions to the problem:

1) Find a way to inject version 0 into installs that already existed. This might be pretty tricky.
2) Evaluate whether we really need the rule about skipping migrations on new installs. This one should be thought about carefully while thinking very hard, but it is possible that we don't need to skip ahead like we do currently. If we can remove that rule, the problem is easily solvable.

It seems to be agreed upon by the (mostly silent) team that we should go with option 2 above. I will alter the migration system so that it does not skip migrations on new installs. I will also alter the developer documentation to describe this behaviour, and to mention that migration writers should write their migrations so that they are safe to run on new installations.

[root@cloud-qe-8 ~]# rpm -q pulp-server

<rbarlow> the change i made was to make it so that new installs still run each migration, even when there is no data in the database
<rbarlow> so one way to verify is to just do that
<rbarlow> make a brand new pulp with no db
<rbarlow> and run pulp-manage-db
<rbarlow> you should see it say that it's running all the migration versions one by one, instead of just saying that it's at the latest migration
