I see what you're saying. In my particular use case I can work around that service status because even if it failed it will just trigger Jenkins to poll and in case of failure to transfer data there will be no new changes for Jenkins to work with. If we would want the --post-service-hook to know that data transfer succeeded or failed, then may be there should be some difference between "service status" and "service process status"? In this case the existing logic works with "service process status" while the --post-service-hook is fed with the "service status" (or name it "data transfer status") Do i make any sense? -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
