project: disable auto-gc for depth=1 in git config

2026-01-08T19:33:40+00:00

During sync, `git checkout` can trigger fetch for missing objects in partial clones. This internal fetch can trigger `git maintenance` or `git gc` and cause delays during the local checkout phase. Set maintenance.auto to false and gc.auto to 0 in during `_InitRemote` if `depth=1` to ensure that implicit fetches spawned by git skip GC.

run_tests/release: require Python 3.9+

2026-01-06T19:36:26+00:00

While we support running `repo` on clients with older Python versions, we don't need to hold the runners & release code back. These are only used by repo devs on their systems to develop & release repo. Python 3.9 was picked due to its typing changs which we've already started using in this code.

tests: drop tox support

2026-01-06T19:32:42+00:00

This hasn't been working out as well as we'd hope. Tox relies on the system having Python versions installed which distros don't tend to carry anymore. Our custom run_tests leverages vpython when possible to run stable Python 3.8 & 3.11 versions which is providing an OK level of coverage in practice.

init: change --manifest-depth default to 1

2026-01-05T14:36:08+00:00

Most users do not care about the manifest history in .repo/manifests/. Let's change the default to 1 so things work smoothly for most people most of the time. For the rare folks who want the full history, they can add --manifest-depth=0 to their `repo init`. This has no effect on existing checkouts. Spot checking Android & CrOS manifests shows significant speedups. Full history can take O(10's seconds) to O(minutes) while depth of 1 takes constant time of O(~5 seconds).

sync: Add heuristic warning for bloated shallow repositories

2025-12-10T19:34:40+00:00

For clone-depth="1" repositories that are dirty or have local commits, add a check at the end of sync to detect excessive git object accumulation. This prevents silent performance degradation and disk exhaustion in large prebuilts repos where automatic GC is typically disabled from https://gerrit.googlesource.com/git-repo/+/7f87c54043ce9a35a5bb60a09ee846f9d7070352 Bug: 379111283 Change-Id: I376f38e1555cc6e906d852f6e63dc1c8f6331b4f Reviewed-on: https://gerrit-review.googlesource.com/c/git-repo/+/534701 Commit-Queue: Gavin Mak Reviewed-by: Mike Frysinger Tested-by: Gavin Mak
