NIFIREG-205: Allow Git repo to delete a flow with snapshot version 0
----
> NiFi Registry DB gets out of sync with git repository, no apprent remediation
> -----------------------------------------------------------------------------
>
> Key: NIFIREG-205
> URL: https://issues.apache.org/jira/browse/NIFIREG-205
> Project: NiFi Registry
> Issue Type: Bug
> Environment: Centos 7.5
> Reporter: Dye357
> Assignee: Koji Kawamura
> Priority: Major
>
> I've observed a couple issues with the GitFlowPersistenceAdapter:
> # When adding a new process group to NIFREG If for any reason the git
> repository is in a "dirty" (untracked file) state the adding of the process
> group fails. However an entry is still created in the DB with a version of 0.
> Once in this state you cannot delete the flow from NIFIREG and you cannot
> restart version control from nifi with the same name. I assume the only way
> to fix this is to manually go into the DB and delete the record.
> # When using Remote To Push, if the push fails the same behavior in #1 is
> exhibited. It's not reasonable to expect that a push will always succeed. The
> remote git repository could be offline for maintenance etc...
> Steps to reproduce:
> # Start nifi registry with an empty db and clean git repo.
> # add an untracked file to the git repo but do-not commit it.
> # Start a processgroup under version control.
> # Expect Failure in Nifi UI
> # Expect Exception in Log saying untracked files in git repo.
> # Delete flow from nifi-registry using Actions -> Delete.
> # Expect Failure case, recieve error deleting flow message.
> # Refresh nifi-registry UI - flow is still present, version is 0.
