feat(codex): start idle 5-hour windows with a real new-session request - #5834
terrytan95 wants to merge 1 commit into
Conversation
Opt-in codexPool.startIdleWindows routes one never-bound request to a pool account whose recorded short window reads 0% with a reset a full window after the observation, so a real request starts its reset clock instead of a synthetic warmup. Bound conversations, pins and independent quota scopes are unaffected; each account is steered once per window. Refs lidge-jun#5833

Exclude released conversations from idle-window placement.
A released thread has entry === undefined, but releaseReason or a pending release reason shows that it was previously bound. The current checks at src/codex/routing.ts:790 and src/codex/routing.ts:1096 can therefore send that continuing conversation to an idle-window account. This violates the startIdleWindows contract for a “brand-new, never-bound conversation.” The ordinary strategy picker also treats the thread as unbound, and lineage selection does not make it never-bound.
Suggested fix
const entry = threadId ? getThreadAffinity(threadId, quotaScope) : undefined;
+ const pendingReleaseReason = threadId ? peekPendingReleaseReason(threadId) : undefined;
...
- const unstartedPreview = entry ? null : pickUnstartedWindowCodexAccount(config, threadId, now, quotaScope, selectionOptions, false);
+ const unstartedPreview = entry || pendingReleaseReason !== undefined
+ ? null
+ : pickUnstartedWindowCodexAccount(config, threadId, now, quotaScope, selectionOptions, false);
...
- const unstarted = entry === undefined ? pickUnstartedWindowCodexAccount(config, threadId, now, quotaScope, selectionOptions, true) : null;
+ const unstarted = entry === undefined && releaseReason === undefined
+ ? pickUnstartedWindowCodexAccount(config, threadId, now, quotaScope, selectionOptions, true)
+ : null;Add coverage for a thread whose affinity was cleared by an outcome.

Require the five-hour window described by the setting.
shortWindowSeconds > 0 also accepts a recorded one-hour window. If that record shows 0% usage and a reset one hour after observation, this selector steers a request even though codexPool.startIdleWindows promises a five-hour window. Require the intended duration, or explicitly define and document which durations the setting supports.

Summary
codexPool.startIdleWindows(off by default). When a brand-new conversation (no thread binding, shared quota scope) arrives and an eligible pool account's last recorded 5-hour window reads 0% with a reset about one full window after the observation, that one real request is routed to it, so the account's reset clock starts. Routing then returns to the configured strategy.codexQuotaAutoRefresh, which dispatches a warmup).structure/providers/openai-accounts.md.Open question (also in the issue): the "not started" shape is inferred, not yet checked against a captured live idle-account response. Detection uses a one-minute tolerance and fails closed to ordinary routing.
