fix(codex): stalled HTTP 429 retries end with an explicit failure instead of hanging - #23842
Hylouis233 wants to merge 32 commits into
Conversation
The Codex CLI retries rate-limited model requests itself and only reports an `error` notice with `willRetry: true`. With a long Retry-After it sleeps for the full value and emits nothing, so the turn, and any delegated task waiting on it, stays running indefinitely. Bound the wait in the adapter. Each rate-limited retry notice gets the Retry-After delay when the error text carries one, or exponential backoff (5s doubling, capped at 5 minutes), plus 60s for the retried request to show progress. Past attempt 5, a Retry-After above 5 minutes, or a missed deadline ends the turn as a retryable usage-limit failure with code `rateLimitRetryExhausted` and the reset time when known, then interrupts the native turn. Any progress or newer notice re-arms the bound.
Follow-ups to the stalled 429 retry bound: - Parse the HTTP-date form of Retry-After relative to the notice time. - Treat a 429 named only in the error text as rate-limited when Codex reports no HTTP status; an explicit non-429 status still wins. - Clear the pending deadline when the turn resumes into context compaction, and ignore late error notices after exhaustion. - Interrupt the native turn, and every active descendant turn, before publishing the terminal. Descendants are re-scanned under the terminalization permit, so a nested turn started mid-teardown is either stopped or handled by the late-subagent path. - When Codex does not acknowledge the interrupt within 10s, keep the turn active instead of reporting it idle. Fail it once Codex reports turn/completed, or after 60s, and mark the thread broken so the next turn resumes it instead of reusing a thread that may still be retrying. Subagent threads in that state are published as errored. - Close a subagent's retry item with the rate-limit failure instead of the original transport error. - Drive the retry tests from observable milestones and TestClock instead of yield loops and live timeouts.
When the 429 deadline or the unconfirmed-stop bound interrupts a descendant and Codex never acknowledges that interrupt, mark the descendant abandoned before finalizing it so its thread is published as errored instead of idle while the native turn may still be running.
Stop's late-descendant pass now marks each turn whose turn/interrupt Codex acknowledged, so a nested turn left with an unconfirmed 429 stop is published idle rather than errored once Stop confirms it stopped.
turn/completed records "ended" before it waits for the terminalization permit, so the abandonment checks the containment again right after its descendant scan instead of overwriting a confirmed end with "abandoned".

ApprovabilityVerdict: Needs Human Approval Macroscope's review found this PR requires human approval — This PR adds substantial production concurrency and terminalization logic that changes default Codex retry behavior, including stopping provider and descendant work and marking threads broken when containment is uncertain. The implementation also has an unresolved race involving descendant cleanup during root completion, so the lifecycle behavior warrants human review. Needs human approval because:

Explanation
The description is detailed and follows the template's main sections. It has a Problem section that explains the silent hang after an HTTP 429 and gives the issue reference. It has a Change section that describes the retry policy, classification, the ending of the turn, and the unconfirmed-stop path. It has a Scope and approval section that links issue 17503, states that the issue is not yet triaged, and offers to narrow scope. It has a Verification section that lists the commands, test counts, the observed failure before the fix, and the items not verified. It also names the agent used and the model. Scope approval is the weak point: the linked issue has no maintainer triage or approval comment, and the description admits this. The template requires explicit maintainer approval or a valid exemption for a change of this size, so that part is incomplete. The takeover note also says the PR is waiting and not ready to merge, with an unresolved persistence ownership blocker. The description is long and the title is not included in the body, but the required information is present.
Resolution
Add explicit maintainer approval to the Scope and approval section. Link a triaged bug issue or a discussion that records maintainer approval of the direction and scope, and include the approval comment. If the author wants the exemption for a small, focused fix instead, explain why this change qualifies. This change adds a new rate-limit policy, a helper module, and a multi-commit unconfirmed-stop path, so the exemption is unlikely to apply. Also resolve or document the unresolved persistence ownership issue for reassigned provider-turn rows before the description states that the change is ready. Confirm that the Verification section has no claims that conflict with the takeover note. Consider moving the takeover verification note out of the description, or label it clearly as a separate review, so the description stays focused on the author's change.

A root whose 429 stop went unacknowledged waits for turn/completed. That event finalized the root at once and cancelled the bounded wait, so a nested turn a subagent started during the wait was never stopped and the root terminal reported it as still running. turn/completed now stops the active lineage before the root fails, with the same rescan-under-permit loop the bounded wait uses, so a nested turn either is stopped first or starts after the root is terminal.
The deadline finalized stopped descendants with the time it captured before interrupting the root. A nested turn that started while that interrupt was in flight then completed before it started. Descendants now settle at the time their interrupts finished, as the bounded wait already does.
"retry after N" was always read as seconds, so "retry after 2 minutes" became a 2 second delay and "retry after 500ms" a 500 second one. The retry-after value now takes an optional unit, as "try again in" already did, and a retry-after-ms header is read as milliseconds. A bare value stays delay-seconds.
A descendant whose own 429 interrupt went unanswered stays "unconfirmed". When the root's lineage stop later interrupts it and Codex acknowledges, the descendant was still published as an errored thread, because only Stop recorded that acknowledgement. Record it for the lineage stop too, so a confirmed stop leaves the thread idle.

Resolve the CodexAdapterV2 turn finalization conflict by keeping the permit-holding finalizer and carrying over the native subagent parent wake from main.
A root turn whose 429 interrupt Codex never confirmed ends with a broken thread disposition, but that only reaches the projection. A provider session that stays live drops a loaded thread only when it sees the thread errored, so the next turn could start directly on the native thread that may still be retrying. Publish the root thread as errored before its terminal, as the subagent path already does, so the next turn resumes it instead.
When the root's stop stays unconfirmed, the bound fallback stopped each active nested turn and waited up to 10s for its interrupt, then rescanned. One silent subagent pushed the root terminal past the bound. At the bound, send the nested turns' interrupts without waiting, settle them and the root under one terminalization permit, and publish the nested turns' threads as broken since their stop was not confirmed.

…firmed A turn/interrupt reply only acknowledges the request; turn/completed is the authoritative signal that a turn stopped. When the 429 deadline interrupted the root or a descendant, a bare reply was taken as confirmation, so the turn could be settled as reusable while Codex was still running it. Wait up to 10 seconds after the interrupt for the turn to end. A root that does not end in time moves to the unconfirmed bound and is reported broken; a descendant that does not end in time is abandoned and its thread marked errored.

…eted A turn/interrupt reply only accepts the request. Stop and the late descendant pass treated Codex's reply as confirmation, so a 429 turn still waiting unconfirmed was published reusable (root) or idle (subagent) while Codex could still be retrying it natively. Treat "unconfirmed" as uncontained regardless of interrupt replies; only turn/completed moves the turn to "ended". Drop the now-unused rateLimitStopAcknowledged flag.

Note Written by thanks @Hylouis233. your retry policy, retry-after parsing, progress cancellation, and explicit usage-limit failure are preserved. i merged current main into your existing branch, shortened the production comments, and added bounded background-terminal cleanup before settlement. cleanup rescans commands that start during interruption, holds child completion until cleanup finishes, and claims descendants before the root interrupt wait. no replacement pr or rewritten contributor commits. verification on real web → session manager → codex 0.164.0 → local http 429 endpoint verification, on
@Hylouis233, please also note two upstream protocol limits: codex's 429 notification omitted the response's retry-after header, so this case uses the fallback deadline and has no reset time; command notifications without a provider process handle cannot establish OS-process termination. cleanup here uses only provider-owned handles. desktop/mobile and real descendant processes were not exercised; descendant races are covered by replay tests. the evidence below predates only the final child-ownership fix. |

@maria-rcks thank you for taking this on the existing branch — merging current main, keeping the retry policy / Retry-After parsing / progress cancellation / explicit usage-limit failure, and adding the bounded background-terminal cleanup (rescans, child completion hold, descendant claim) before settlement. Appreciate the verification notes on |

Note Written by Verified in a real dev environmentpartial verification only. the changed 429 behavior is not verified by this run. i read the diff, description, discussion and all 23 pr commits. the pr was open and no listed commit was authored by juliusmarminge or t3dotgg. i installed and ran github/main (1abf368) in /home/user/main first, stopped its captured server process group, then installed and ran exact pr head 7589932. only one dev server ran at a time. no source changes or pushes. using the repository playwright and /usr/bin/google-chrome, i paired each web client, added the real checkout as a project through the app, selected codex gpt-6.1-sol, and submitted real provider turns through the local proxy. no replay provider, mock responses, fixtures or demo data.
short runtime transcript, from read-only queries of isolated app databases (utc): the screenshots use the same prompt on main and pr. they prove successful provider integration, not reproduction of the original bug. the clip shows neighboring user-stop behavior, not the 429 deadline. i inspected the captures and checked uploaded video playback and seeking. Not verifiedthe original silent-429 hang did not reproduce on main. real proxy-backed requests succeeded; neither server recorded a 429. under the no-mocks rule, i did not substitute a synthetic 429 endpoint or inject provider frames. the fallback deadline, retry-after/reset reporting, progress cancellation during a retry, descendant/background-terminal containment, unconfirmed-stop abandonment, and fresh-turn recovery after rate-limit exhaustion remain unverified in the real app. the earlier recovery concern remains open; ordinary stop recovery does not resolve it. native desktop, ios/android, windows/macos and remote/relay/tunnel behavior were not exercised on this linux web setup. this pass does not establish OS-process containment for 429 cleanup. no code fix is justified by successful neighboring checks alone. outcome: unverifiable for the changed behavior, with neighboring integration checks passed. |

Note Written by maintainer verification at merged main with a merge commit and preserved the capacity retry behavior. the scoped follow-up contains children from earlier capacity attempts in every 429 cleanup path. its regression fails before the fix and passes afterward. blacksmith live browser → orchestration → real codex app-server verification reproduced bounded 429 abandonment and a successful follow-up response. however, the follow-up reused abandoned native turn runtime transcript (utc): HTTP 429 at 12:13:36; interrupt at 12:14:41; bounded failure at 12:15:51; follow-up at 12:15:53; native completion at 12:16:00. sqlite confirms the failed and completed runs and the reassigned provider-turn row. fault injection returned actual HTTP 429 responses through a local proxy and withheld interrupt delivery to exercise abandonment. the task wrapper disabled provider websockets because websocket handshake 429 did not produce the retry notification. native websocket recovery, desktop/mobile clients, and live descendant-process teardown remain unverified. replay tests cover descendant containment. the two allowed fix rounds are exhausted. |

Note Written by Merged current main into the existing head in Blacksmith verification passed: Live Codex HTTP 429 behavior remains unverified; the adapter checks exercise recorded protocol transcripts. |

Note Written by merge readiness at the contributor merged main during this pass. i continued from that new head and merged the remaining current main commits without conflicts, then pushed to the existing branch without force. hook stop reasons, app thread routing, the 429 containment logic, and the unconfirmed-stop resume guard are preserved. the pr remains the same four files, with 4,730 additions and 308 deletions against main. no new behavior or test files were added in this pass. blacksmith live codex http 429 recovery on this final head, native desktop/mobile, and live descendant process cleanup remain unverified in this pass. the automated checks use protocol replay; they do not establish live provider behavior. no new browser evidence is claimed. this update replaces the previous takeover status rather than adding another comment. |

Thanks @Hylouis233 for the earlier work on stalled Codex 429 retries. Closing this in favor of #33130 by @maria, which addresses the same stuck retry and descendant-turn failure. This branch has not been updated in over a week and main has since changed the adapter; the newer PR is current and merges cleanly. |

Problem
The Codex CLI retries a rate-limited (HTTP 429) model request itself. The only thing the app-server sends is an
errornotification withwillRetry: true. If the response carries a longRetry-After, Codex sleeps for that whole time and sends nothing else. The T3 Code turn then staysrunningwith no further events. Any delegated task waiting on it also hangs, and the user gets no failure, reset time or recovery hint. In the case reported in https://git.cafe/pingdotgg/t3code/issues/17503, a post-tool 429 retry left the turn running for hours.Expected behaviour: the turn either makes progress or ends in a clear, retryable failure that includes the rate-limit reset time when it is known.

turn/interruptto the native turn and to every active descendant (subagent) turn. Each request is bounded to 10s. Descendants are re-scanned under the existing terminalization permit, so a nested turn started during teardown is either stopped or handled by the existing late-subagent path.rateLimitRetryExhausted, includingresetAtwhen known.Late
turn/completedorerrorframes for that turn are ignored, so they cannot overwrite the failure. A subagent turn closes its retry item with the same failure.Unconfirmed stop. If Codex does not acknowledge the interrupt (it times out or errors), the turn is not reported idle while Codex may still be retrying. It stays active until Codex sends
turn/completed, or for at most 60s more. It is then failed and the thread disposition is set tobroken, so the next turn runsthread/resumeinstead of reusing a loaded thread that may still be retrying. A subagent thread in this state is published aserror. The same applies to a descendant whose own interrupt was not acknowledged (at the deadline or at the end of the 60s bound): it is marked abandoned, so its thread is published aserrorrather thanidle. A later user Stop that Codex does acknowledge for such a descendant counts as a confirmed stop, so that thread returns toidle. Ifturn/completedarrives while the abandonment waits for the terminalization permit, the abandonment re-checks the containment state and leaves the confirmed end in place. A user Stop that Codex does not acknowledge keeps the samebrokendisposition.The PR has these commits (plus a merge of
main):idle.Scope and approval
This is a reliability fix for one problem: a Codex turn hanging silently after an HTTP 429. It links https://git.cafe/pingdotgg/t3code/issues/17503, which has not been triaged by maintainers yet. I'm happy to wait for triage, or to narrow the scope (for example, to the first commit only) if you prefer.
Verification
How the problem was confirmed. The adapter tests replay Codex app-server transcripts. One has a tool call followed by an
errornotice withwillRetry: trueand HTTP 429, then silence. Against the unchanged adapter at044f07257(the Codex adapter and its tests are identical at22840ab9, themainthis branch now merges), I ran the new 429 tests (vp test run src/orchestration-v2/Adapters/CodexAdapterV2.test.ts -t 429):ends a stalled post-tool 429 retry with an explicit failurecases failed withexpected [] to have a length of 1 but got +0: no terminal event was ever produced after the deadline.How it was tested.

fault injection returned actual HTTP 429 responses through a local proxy and withheld interrupt delivery to exercise abandonment. the task wrapper disabled provider websockets because websocket handshake 429 did not produce the retry notification. native websocket recovery, desktop/mobile clients, and live descendant-process teardown remain unverified. replay tests cover descendant containment. the two allowed fix rounds are exhausted.
