Mike Frysinger 347f9ed393 sync: rework selfupdate logic ... The current logic has a downside in that it doesn't sync to the latest signed version available if the latest commit itself is unsigned. This can come up when using the "main" branch as it is sometimes signed, but often not as it's holding the latest merged commits. When people use the main branch, it's to get early testing on versions tagged but not yet released, and we don't want them to get stuck indefinitely on that old version of repo. For example, this series of events: * "stable" is at v2.12. * "main" is tagged with v2.13. * early testers use --repo-rev main to get v2.13. * new commits are merged to "main". * "main" is tagged with v2.14. * new commits are merged to "main". * devs who had synced in the past to test v2.13 are stuck on v2.13. repo sees "main" is unsigned and so doesn't try to upgrade at all. The only way to get unwedged is to re-run `repo init --repo-rev main`, or to manually sync once with repo verification disabled, or for us to leave "main" signed for a while and hope devs will sync in that window. The new logic is that whenever changes are available, we switch to the latest signed tag. We also replace some of the duplicated verification code in the sync command with the newer wrapper logic. This handles a couple of important scenarios inaddition to above: * rollback (e.g. v2.13.8 -> v2.13.7) * do not trash uncommitted changes (in case of ad-hoc testing) * switch tag histories (e.g. v2.13.8 -> v2.13.8-cr1) Change-Id: I5b45ba1dd26a7c582700ee3711f303dc7538579b Reviewed-on: https://gerrit-review.googlesource.com/c/git-repo/+/300122 Reviewed-by: Jonathan Nieder <jrn@google.com> Reviewed-by: Michael Mortensen <mmortensen@google.com> Tested-by: Mike Frysinger <vapier@google.com>		2021-04-09 03:16:45 +00:00
