Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Cause: If the final line of a log was not newline-terminated, it was not displayed in the resource log view. Consequence: Single line logs or logs that ended without newline termination would be missing content in the log view. Fix: Update log view to include the final log line even when it is not newline-terminated. Result: Log view shows entire log content, even when final line is not terminated with a newline.

We need newer nightly to test the fix, 4.6.0-0.nightly-2020-09-29-170625 doesn't include the fix yet

Changing QA Contact to Siva then he can verify the bug when there is new build during Chinese holiday

Comment 4 Siva Reddy 2020-10-06 09:16:37 UTC
The pod logs now show the output. Hence moving this bug to verified.

1. Create a new project and the create a pod with the pod.yaml attached.
   oc create new-project
   oc create -f pod.yaml
2. Log in to the web console as kube admin
3. Navigate to PageSideBar>Workloads>Pods
4. Select the created project from the drop down
5. Click on the newly created pod in the page displayed.
