(the actual source diffs committed) No. Git keeps the reachable DAG. So if the DAG is part of development that is merged into one of your long running branches, or if you keep around the branch that points to it, it will never go away. > My (possibly flawed) understanding was that it drops any DAG sections > that are not referenced by valid refs which are older than the GC > timeout. Yes. So the way to "forget" about some history is to stop referencing it. And then, after a grace period, it will be removed. > Are you saying this GC process will never collect source diffs in the > DAG? No, but it will only remove unreferenced things. And things only become unreferenced through explicit user action. So you don't have to worry about git GCing your work unexpectedly. You do have to worry about git GCing things you have explicitly told it to delete. -Peff -- 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
