Issue #8942

Updated by pulpbot almost 3 years ago

 

 **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:
