Add limit_5h and limit_weekly options as alternatives to reserve_5h
and reserve_weekly for capping credential utilization. The two are
mutually exclusive per window.
Fix computeAggregatedUtilization to scale per-credential utilization
relative to each credential's cap before averaging, so external users
see correct available capacity regardless of per-credential caps.
Fix pickLeastUsed to compare remaining capacity (cap - utilization)
instead of raw utilization, ensuring fair comparison across credentials
with different caps.
InterfaceUpdated() writes reverseContext and reverseCancel without
synchronization while connectorLoop/connectorConnect goroutines
read them concurrently. close() also accesses reverseCancel without
a lock.
Fix by extending reverseAccess mutex to protect these fields:
- Add getReverseContext()/resetReverseContext() methods
- Pass context as parameter to connectorConnect
- Merge close() into a single lock acquisition
- Use resetReverseContext() in InterfaceUpdated()
Allow two CCM/OCM instances to share credentials when only one has a
public IP, using yamux-multiplexed reverse connections.
Three credential modes:
- Normal: URL set, reverse=false — standard HTTP proxy
- Receiver: URL empty — waits for incoming reverse connection
- Connector: URL set, reverse=true — dials out to establish connection
Extend InterfaceUpdated to services so network changes trigger
reverse connection reconnection.
aTLS.NewListener returns *LazyConn, not *tls.Conn, so Go's
http.Server cannot detect TLS via type assertion and falls back
to HTTP/1.x. When ALPN negotiates h2, the client sends HTTP/2
frames that the server fails to parse, causing HTTP 520 errors
behind Cloudflare.
Wrap HTTP handlers with h2c.NewHandler to intercept the HTTP/2
client preface and dispatch to http2.Server.ServeConn, consistent
with DERP, v2rayhttp, naive, and v2raygrpclite services.
Extract credential interface from *defaultCredential to support both
default (OAuth) and external (remote proxy) credential types. External
credentials proxy requests to a remote ccm/ocm instance with bearer
token auth, poll a /status endpoint for utilization, and parse
aggregated rate limit headers from responses.
Add allow_external_usage user flag to control whether balancer/fallback
providers may select external credentials. Add status endpoint
(/ccm/v1/status, /ocm/v1/status) returning averaged utilization across
eligible credentials. Rewrite response rate limit headers for external
users with aggregated values.
CCM: Fix 1M context detection - use prefix match for versioned
beta strings (e.g. "context-1m-2025-08-07") and include cache
tokens in the 200K threshold check per Anthropic billing docs.
OCM: Add GPT-5.4 family pricing (standard/priority/flex) with
extended context (>272K) premium pricing support. Add context
window tracking to usage combinations, mirroring CCM's pattern.
Update normalizeGPT5Model defaults to latest known models.
Support the OpenAI Responses WebSocket API (`wss://.../v1/responses`)
for bidirectional frame proxying with usage tracking.
Fix Codex CLI client config examples to use profiles and correct flags.
Update openai-go v3.24.0 → v3.26.0.
