[jira] [Created] (BEAM-14536) Offsetrange tracker panics when splitting at 0.0 without claiming work

Danny McCormick created BEAM-14536:
--------------------------------------

             Summary: Offsetrange tracker panics when splitting at 0.0 without claiming work
                 Key: BEAM-14536
                 URL: https://issues.apache.org/jira/browse/BEAM-14536
             Project: Beam
          Issue Type: Bug
          Components: sdk-go
            Reporter: Danny McCormick


Right now, if you try to call TrySplit on an offsetrange restriction with a fraction of 0.0 and without first claiming work, it sets the primary restriction to \{Start, Start-1}. This causes newSplitResult to panic - https://github.com/apache/beam/blob/ff39fcb5229b15140e41a61bd09f7d590730e93a/sdks/go/pkg/beam/core/runtime/exec/sdf.go#L859
