superproject: Don't exit if superproject tag doesn't exist in manifest.

2021-06-16T04:48:35+00:00

Don't exit if there are missing commit ids in superproject. This change implements the following suggestion from delphij@: "we should note the event (so we know that --use-superproject but there were some errors, e.g. manifest didn't specify commit id for some reason, or if there is no superproject but --use-superproject is used), print out a message telling the use that this is not support, but continue as if --no-use-superproject was specified?" Changes: superproject: + Added git_trace2_event_log as an argument to the constructor. + Sync method returns SyncResult a NamedTuple of ++ success - True if sync of superproject is successful, or False. ++ fatal - True if caller should exit, Or False. + UpdateProjectsRevisionId returns UpdateProjectsResult a NamedTuple of ++ manifest_path - path name of the overriding manifest file instead of None ++ fatal - True if caller should exit, Or False + _GetAllProjectsCommitIds returns CommitIdsResult a NamedTuple of ++ commit_ids - a dictionary with the projects/commit ids on success, otherwise None ++ fatal - True if caller should exit, Or False + Added _SkipUpdatingProjectRevisionId a helper function to see if a project's revision id needs to be updated or not. This function is used to exclude projects from local manifest file. + Added the following error events into git_trace2_event_log ++ If superproject is missing in a manifest ++ If there are missing commit ids for projects. command.py: + Deleted unused import - platform + Added git_trace2_event_log as a member so all subcmds can log error events. main.py: + Initialized git_trace2_event_log as a member of command object. init.py: + Deleted unused import - optparse init.py: + Called sys.exit only if Sync returns exit=True sync.py: + Called sys.exit only if Superproject's UpdateProjectsRevisionId returns exit=True + Reloaded the manifest only if manifest path is returned by UpdateProjectsRevisionId. If not, fall back to the old way of doing repo sync. test_git_superproject: + Added code to verify error events are being logged. + Added a test for no superproject tag + Added test for UpdateProjectsRevisionId not updating the revision id with the commit ids. Tested the code with the following commands. + Positive test case with aosp-master. $ repo_dev init -u persistent-https://android.git.corp.google.com/platform/manifest -b master --use-superproject NOTICE: --use-superproject is in beta; report any issues to the address described in `repo version` .../android/aosp/.repo/exp-superproject/925043f706ba64db713e9bf3b55987e2-superproject.git: Initial setup for superproject completed.

sync: Sync submodules correctly again

2021-05-20T16:23:10+00:00

Commit b4429439 (sync: refactor main fetch loop) broke syncing of submodules with sync-s="true". The first `repo sync` would just fetch the superrepo, while the second `repo sync` would fetch the submodules. This was due to the new _FetchMain() function not passing back the all_projects variable that it had modified.

ssh: rewrite proxy management for multiprocessing usage

2021-05-10T21:16:06+00:00

We changed sync to use multiprocessing for parallel work. This broke the ssh proxy code as it's all based on threads. Rewrite the logic to be multiprocessing safe. Now instead of the module acting as a stateful object, callers have to instantiate a new ProxyManager class that holds all the state, an pass that down to any users.

ssh: move proxy usage to the sync subcommand

2021-05-10T21:10:29+00:00

The only time we really need ssh proxies is when we want to run many connections and reuse them. That only happens when running sync. Every other command makes at most two connections, and even then it's only one or none. So the effort of setting up & tearing down ssh proxies isn't worth it most of the time. The big reason we want to move this logic to sync is that it's now using multiprocessing for parallel work. The current ssh proxy code is all based on threads, which means none of the logic is working correctly. The current ssh design makes it hard to fix when all of the state lives in the global/module scope. So the first step to fixing this is top move the setup & teardown to the one place that really needs it: sync. No other commands will use proxies anymore, just direct connections.

sync: Recommend using --no-use-superproject if sync fails.

2021-05-07T20:15:50+00:00

If superproject was not available for a branch, then the next repo sync would also fail because --use-superproject is remembered across repo init. In such cases, hoping the hint to to use --no-use-superproject will help.
