P4DTI issue job000421

TitleMigration of jobs to Bugzilla fails if a job is owned by a non-existent user
Assigned userGareth Rees
DescriptionIf you have jobs in Perforce that are owned by a non-existent user, or a user who's been deleted, then the P4DTI can't migrate those jobs to Bugzilla.
You get the following error message:
Bugzilla module error: (P4DTI-514X) There is no Bugzilla user corresponding to Perforce user 'spong'.
AnalysisWhen the replicator comes to apply the field map, it tries to translate the Assigned_To field using the strict version of the user_translator (with allow_unknown = 0). This fails before prepare_issue_advanced has a chance to do anything with the less strict version of the user_translator (with allow_unknown = 1).
You can work around this problem edit jobs owned by non-existent users so that they're owned by somebody else (we could assist this by adding this check to the check_jobs script). But I bet this will come up a lot.

Possible solutions:
1. Set allow_unknown = 1 during migration. All unknown users end up as the special Bugzilla user in Bugzilla; when we refresh we get the P4DTI user. Information lost.
2. Leave it as it is; stop with an error we find an unknown user. Force the admin to either change the job or create a user in Bugzilla.
3. We could create Bugzilla users for all these unknown users during migrate_users (creating them disabled?). But we don't know which fields have users in them, which we don't.
4. Check this case during check_jobs.py; force the admin to make the User field valid for all jobs. (Admin could add user to Perforce but in general they don't have any licences left.) Not good because we don't know which fields to check at this stage since they haven;t yet written translate_jobspec.
5. Split the migration steps into (a) a translate jobspec step and (b) the migration step itself. Then at step (b) we would know which fields were user fields and then we could apply solutions 3 and 4.
