Simon Bence commented on NIFI-10973:
------------------------------------
Hey [~markap14]!
Thanks for taking care of this! So as it turned out -based on the reproduction
of the case you mentioned- this behaviour had a different root cause, namely,
the newly introduced "storageLocation" field needed to be additionally passed
during update in order to be able to recognize the version control properly.
This I added within this ticket and I plan to double check other possible
occuerances, but I will do it not as part of this given ticket if you all right
with that.
> NiFi Registry Client with Nested PGs/Flows - sync issue (again)
> ---------------------------------------------------------------
>
> Key: NIFI-10973
> URL: https://issues.apache.org/jira/browse/NIFI-10973
> Project: Apache NiFi
> Issue Type: Bug
> Components: NiFi Registry
> Affects Versions: 1.19.1
> Reporter: Josef Zahner
> Assignee: Simon Bence
> Priority: Critical
> Fix For: 1.20.0
>
> Attachments: Nested_PG_Test.xml, Sync_issue_State.png,
> Sync_issue_local_changes.png
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> We just upgraded to NiFi 1.19.1 and we have an issue with the NiFi Registry
> Client in combination with nested PGs (parent PG and child PGs are both
> commited as NiFi Registry flows).
> Steps to reproduce the issue (based on the attached template xml):
> Hint: {color:#57d9a3}Green Color {color}-> NiFi Registry flow Master;
> {color:#4c9aff}Blue Color{color} -> Secondary NiFi/Canvas where you import
> the flow from Registry
> * {color:#57d9a3}Import the XML template{color}
> * {color:#57d9a3}Start Version Control for "Child PG"{color}
> * {color:#57d9a3}Start Version Control for "Parent PG"{color}
> * {color:#4c9aff}On an independent canvas/nifi click "Add Process Group" and
> "Import from Registry", select the "Parent PG" flow{color}
> * {color:#57d9a3}On the original "Child PG" rename the only existing
> processor, eg. to "UpdateCounter New"{color}
> * {color:#57d9a3}Commit the change for the "Child PG" (Processor
> Rename){color}
> * {color:#57d9a3}Commit the change for the "Parent PG" (Version change of
> "Child PG"){color}
> * {color:#4c9aff}Now click "Change Version" on the other NiFi/Canvas and
> switch to the newest version for the "Parent PG", which seems to be
> successful. *However* *now we are hitting the issue, NiFi shows a successful
> change, but NiFi shows as well "Local Changes" for the "Child PG" (not for
> the "Parent PG"). To get a good state you have to click to "Revert Local
> Changes" on the "Child PG" which makes no sense, it should directly sync the
> "Child PG" according to the commited version. At least the version number of
> the "Child PG" has been changed but not the real configuration as you see
> below in the screenshots. It shows that there has been a component name
> change, which is true for the version but to get to the new version we have
> to revert the local changes*{color}
>
> Screenshots with the Failure State below, "Parent PG" is in sync, but not the
> "Child PG". The only thing I've done is to change the Version on the "Parent
> PG":
> {color:#4c9aff}*!Sync_issue_State.png!*{color}
>
> {color:#4c9aff}*!Sync_issue_local_changes.png!*{color}
