sync, init: support repo.smartsync config and --head alias

2026-10-21T18:22:58+00:00

Allow users to configure Smart Sync as the default for a checkout: * Add `ManifestProject.smart_sync` backed by `self.config.GetBoolean("repo.smartsync")`. * Add `-s`/`--smart-sync` and `--no-smart-sync`/`--head` to `repo init` to persist `repo.smartsync` in the manifest project config. * Add `--head` as an alias for `--no-smart-sync` in `repo sync` and `repo init`. * Update `Sync._ResolveSmartSyncOption` so `ManifestProject.smart_sync` takes precedence over `` while remaining overridable by per-invocation `repo sync` CLI flags.

sync: Provide a CLI command to opt in/out of smartsync for a user.

2026-10-19T19:20:06+00:00

Add a boolean `sync.smartsync` setting in the per-user repo config (~/.repoconfig/config): * true: smart sync by default, as if -s were passed. * false: never smart sync by default, even if the manifest enables it. * unset: follow the manifest default, as before. Add docs/repoconfig.md as the user facing documentation for ~/.repoconfig/config and its settings, and point smart-sync.md and the `repo sync` help at it.

sync: Add GetApprovedManifestV2 with named request options

2026-10-14T10:30:36+00:00

Smart sync calls GetApprovedManifest(branch[, target]) over XML-RPC, which only supports positional arguments. Adding new request options that way does not scale. Add a GetApprovedManifestV2 method that takes a single struct of named options and returns a struct: request: {branch, target?, best_effort?} response: {success, manifest_xml?, error_message?} Servers must ignore unknown options, so new options (e.g. criteria for selecting a good build) can be added without another method. The first new option is `best_effort`. repo sets it when smart sync was enabled implicitly by the manifest's sync-smartsync="true" default rather than by -s. The server may decline a best_effort request (e.g. for rollout or cohort gating) by returning success=false. The client still owns the fallback policy: declined implicit requests fall back to a regular sync, while explicit -s requests fail as before. If the server does not implement GetApprovedManifestV2, repo falls back to the legacy GetApprovedManifest call.

sync: keep smart sync override with -l

2026-10-12T09:14:30+00:00

Splitting a sync into `repo sync -n` followed by `repo sync -l` should end up in the same state as a single `repo sync`. With smart sync it does not always: -n fetches the revisions pinned by the smart sync manifest and saves it as smart_sync_override.xml, but the following -l deletes that override and checks out ToT instead, unless the manifest sets sync-smartsync="true". So `repo sync -s -n` + `repo sync -l` lands on ToT, while `repo sync -s` lands on the pinned revisions. Without an explicit -s or -t, -l does not contact the manifest server, so it cannot choose new pins itself; the only consistent choice is to keep the override the previous -n left behind. Do that regardless of the manifest default. Syncs that choose a manifest themselves still replace or remove the override as before: any sync without -l, and -l combined with -s, -t, -m, --superproject-revision or --no-smart-sync. Smart sync stays non-sticky for regular syncs, and `repo sync -l --no-smart-sync` still discards the override to check out ToT.

sync: keep --superproject-revision across manifest reloads

2026-10-09T19:56:07+00:00

When --superproject-revision moves `.repo/manifests`, the manifest is reloaded, discarding the pinned superproject. _UpdateProjectsRevisionId then read gitlinks from the superproject's default branch instead, pinning failed, and projects synced unpinned. Apply the revision in _ConfigureSuperproject so it is re-applied after every reload.
