fix(auth): stop auth login reporting success while Flow routes to /about (#902) - #904
Conversation
…about (#902) A pending Google "Confirm it's you" leaves the cookies valid, so the session probe answered in 0.4 s and the login closed Chrome before Flow's client-side hop to flow.google.com/about landed, then printed [OK] on a broken account. The shared login poll now watches a flow.google.com landing for up to 3 s before ending the wait. On /about it keeps Chrome open and tells the user to finish Google's check; closing or timing out there raises the new IdentityRecheckPendingError (exit 12), and RealChromeStrategy no longer lets the #849 on-disk check overrule it (that check reads the same healthy cookies). Labs-served logins are not watched and close as before.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Require an app landing before accepting a pending recheck as complete.
If the user leaves /about for Google's password challenge during page.request.get, _landed_on_public_page returns false while the session response can still be AUTHENTICATED. This branch then reports success and closes Chrome before the check finishes. The migrated_stop branch has the same failure. Once recheck_pending is true, require a settled Flow app landing before either success branch. Update test_completing_the_recheck_ends_in_success to assert that its page reaches self.APP; it currently passes while the page is still on Google's host.

…iva#881) Exit 31 on a flow.google.com/about redirect said only to open the project in a browser. The 2026-09-23 spike measured the cause on the account that reproduces it: a pending Google 'Confirm it's you' with healthy cookies, which 'gflow auth login' now waits on (ffroliva#902/ffroliva#904). The hint says so, without claiming it is the only cause. USAGE's exit-31 row follows.
Closes #902
What
gflow auth loginreported[OK] Flow session verifiedon an account where Google is waiting for the owner to "Confirm it's you". In that state the cookies stay valid, so the session probe answered in 0.4 s. Chrome closed before Flow's client-side hop toflow.google.com/aboutcould land, and every command afterwards still exited 31.Fix (root: the shared login poll,
poll_session_until_authenticated)flow.google.comlanding is watched for up to 3 s forflow_landing_kind(url) == "public". The hop was measured at about 340 ms, so this allows roughly 10x that. Labs-served logins are not watched and close as fast as before./about: Chrome stays open, the eventauth_login_identity_recheck_pendingis logged, and the user is told to press the page's main button and finish Google's check. Once the page reaches the app, the login succeeds as before./aboutraises the newIdentityRecheckPendingError. It subclassesAuthLoginTimeoutError, so it exits 12 with no new exit code. It raises whateverraise_on_closeis set to, because the fallback oracle would read the same healthy cookies.RealChromeStrategy.loginlets it through: the auth login: the browser never closes on a migrated account — the auto-close oracle is the labs endpoint that never answers #849 "ask the disk" rescue is skipped for this error, since that rescue is exactly how the false[OK]would come back._await_flow_sessionno longer rewrites it into the generic timeout.Predict mitigations (CAUTION verdict)
login()./aboutremediation now becomes correct (gflow auth loginwill stop on the check). I left_common.pyalone to avoid colliding with fix(auth): recover from /about landing via Create button and parse batchexecute RPC error envelopes #881. The fix(auth): recover from /about landing via Create button and parse batchexecute RPC error envelopes #881 text still needs to change.Deviation from the predict: it recommended request listeners attached before
goto. I used a URL watch window instead, because the URL keeps the evidence once the hop has landed, so a listener would only save latency. The upgrade path is noted in aponytail:comment.Tests

gflow auth statusandgflow doctorstill report healthy on this state. Both rely on cookies and the server, and fixing them needs a browser launch. That is a sibling issue.Summary by CodeRabbit
