Issue #8942
closedrace condition when deleting a repository and associated distribution
Description
Ticket moved to GitHub: "pulp/pulpcore/2019":https://github.com/pulp/pulpcore/issues/2019
In our katello tests, we have some 'cleanup' code that:
list and then deletes a repository with a given name list and then deletes a remote with a given name list and then deletes a distribution with a given name wait on all the tasks generated from above
This has worked for quite a while, but after upgrading from pulp-container 2.3 to 2.6, we started seeing an error (ISE) from the server:
LookupError: view not found
when trying to list the distributions on the 3rd step.
I'm not sure if the pulp code is running faster, or slower, but it appears that there is a consistent race condition occuring. I can modify the code to poll the tasks after the repo delete, and it seems to work find (so this isn't blocking us)
Here's the full traceback:
