When the access token expires and refreshToken() gets 429, getAccessToken()
returned the error but left credentials unchanged with no cooldown. Every
subsequent request re-attempted the refresh, creating a burst that overwhelmed
the token endpoint.
- refreshToken() now returns Retry-After duration from 429 response headers
(-1 when no header present, meaning permanently blocked)
- getAccessToken() caches the 429 and blocks further refresh attempts until
Retry-After expires (or permanently if no header)
- reloadCredentials() clears the block when new credentials are loaded from file
- Remove go pollUsage() on upstream errors (unrelated to usage state)
pollUsage(ctx) accepted caller context, and service_status.go passed
r.Context() which gets canceled on client disconnect or service shutdown.
This caused incrementPollFailures → interruptConnections on transient
cancellations. Each implementation now uses its own persistent context:
defaultCredential uses serviceContext, externalCredential uses
getReverseContext().
- Add fiveHourReset/weeklyReset to statusPayload and aggregatedStatus
with weight-averaged reset time aggregation across credential pools
- Rewrite response headers (utilization + reset times) for all users,
not just external credential users
- Rewrite WebSocket rate_limits events for all users with aggregated values
- Add proactive WebSocket status push: synthetic codex.rate_limits events
sent on connection start and on status changes via statusObserver
- Remove one-shot stream forward compatibility (statusStreamHeader,
restoreLastUpdatedIfUnchanged, oneShot detection)
- Remove unused onBecameUnusable field from CCM credential structs
(OCM wires it for WebSocket interruption; CCM has no equivalent)
- Replace time.After with time.NewTimer in doHTTPWithRetry and
connectorLoop to avoid timer leaks on context cancellation
- Pass already-resolved provider to rewriteResponseHeadersForExternalUser
instead of re-resolving via credentialForUser
- Hoist reverseYamuxConfig to package-level var (immutable, no need to
allocate on every call)
