当前并发是立即关闭的,如果请求多并发少时会出现轮流抢号情况,加了一个并发等待默10s 和关闭

开启后请求完毕后会等一会,如果一定时间没继续请求才释放

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds Spark-aware dispatch and usage tracking, occupied-request accounting, persisted session-slot buffering, prompt-risk lock filtering, HTTP request normalization, and credential-theft detection updates. Admin and frontend contracts expose the new runtime and settings data.

Changes

Runtime dispatch and usage

Layer / File(s) Summary
Policy-aware dispatch and occupied slots
auth/dispatch_policy.go, auth/store.go, auth/fast_scheduler.go, auth/session_slot_buffer_test.go
Account selection now accepts standard or Spark policies. Occupied requests and session reservations use shared accounting paths. Store mutations move scheduler cleanup outside store locks.
Independent Spark usage
auth/spark_usage.go, proxy/usage_wham.go, database/usage_snapshot.go, auth/spark_usage_test.go, proxy/usage_wham_test.go
Spark usage windows are parsed, persisted, restored, cleared, and evaluated separately from standard account limits.
Proxy policy propagation and fallback
proxy/handler.go, proxy/responses_ws.go, proxy/retry_exclusions.go, proxy/handler_anthropic.go, proxy/handler_test.go
Proxy selection, retries, waits, and successful releases preserve the selected dispatch policy and session affinity. WebSocket fallback learns size thresholds and expands cached continuation history.

Settings and account administration

Layer / File(s) Summary
Session-slot persistence and controls
database/postgres.go, database/sqlite.go, database/sqlite_test.go, admin/handler.go, frontend/src/pages/Settings.tsx, frontend/src/types.ts, frontend/src/locales/*
Session-slot enablement and duration are stored with normalization. Runtime settings change only after persistence succeeds. The admin API and Settings page expose both values.
Account runtime data
admin/account_live.go, admin/account_response_builder.go, admin/accounts_paged.go, frontend/src/api.ts, frontend/src/hooks/useAccountLiveState.ts, frontend/src/components/AccountDetailSheet.tsx, frontend/src/pages/Accounts.tsx
Account responses and account views now show occupied requests and Spark usage data. Usage bars and concurrency badges use the new fields.

Prompt risk and audit navigation

Layer / File(s) Summary
Active lock filtering and audit details
database/prompt_risk_profile.go, admin/prompt_risk_profile.go, proxy/prompt_conversation_lock.go, frontend/src/pages/PromptFilter.tsx, database/prompt_filter.go, database/prompt_policy_incident.go
Risk profiles can prioritize or filter active locks. Restriction responses expose audit metadata. The frontend links restrictions to filtered audit logs.

Request normalization, security, and release

Layer / File(s) Summary
Canonical compaction and envelope cleanup
proxy/compact_via_responses.go, proxy/executor.go, proxy/translator.go, proxy/responses_ws.go
Compaction triggers use canonical input forms. HTTP request preparation removes the top-level WebSocket envelope type while retaining nested types.
Credential-theft detection and release notes
security/promptfilter/patterns.go, security/promptfilter/production_false_positive_regression_test.go, CHANGELOG.md
Credential export detection is separated from generic page export detection. Regression cases cover allowed and blocked prompts. The changelog adds the v2.8.3 release section.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 90fb1

The PR adds configurable session-slot buffering and related account status/reporting changes, but the current version still has security and correctness risks: some credential-export requests may bypass filtering, disabled accounts may continue serving traffic, and persisted usage state may disagree with runtime state. These issues should be fixed or explicitly accepted before merging.

55-90: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Cover the affinity-off fallback branch.

ReleaseForSession falls back to Release when GetAffinityMode() returns AffinityModeOff (auth/store.go Line 6595). No test exercises that branch, so a regression that buffers slots while session affinity is off would pass. Add a case that sets affinity mode to off and asserts accountOccupiedRequests returns 0 right after ReleaseForSession.

9-19: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Add a concurrent test that runs under -race.

The five tests are all single-goroutine. The feature under test is an accounting scheme built from a mutex plus separate atomic counters, and reserveOccupiedAccountSlot updates OccupiedRequests and ActiveRequests in two separate atomic operations. A concurrent test is the only way to cover that interleaving.

Drive N goroutines that repeatedly acquire through NextForSession, then alternate between ReleaseForSession and Release. After all goroutines join and the buffer expires, assert that ActiveRequests is 0 and accountOccupiedRequests is 0, and assert that OccupiedRequests never exceeded maxConcurrency during the run.

💚 Proposed concurrency test
func TestSessionSlotBufferConcurrentAcquireRelease(t *testing.T) {
	account := &Account{DBID: 1, AccessToken: "tok-1"}
	store := newSessionSlotBufferTestStore(4, account)
	store.BindSessionAffinity("owner", account, "")

	var wg sync.WaitGroup
	var overLimit atomic.Bool
	for i := 0; i < 8; i++ {
		wg.Add(1)
		go func(id int) {
			defer wg.Done()
			for n := 0; n < 200; n++ {
				acquired, _ := store.NextForSession("owner", 0, nil)
				if acquired == nil {
					continue
				}
				if accountOccupiedRequests(account) > 4 {
					overLimit.Store(true)
				}
				if n%2 == 0 {
					store.ReleaseForSession(acquired, "owner")
				} else {
					store.Release(acquired)
				}
			}
		}(i)
	}
	wg.Wait()

	if overLimit.Load() {
		t.Fatal("occupied slots exceeded maxConcurrency")
	}

	store.SetSessionSlotBufferEnabled(false)
	if got := atomic.LoadInt64(&account.ActiveRequests); got != 0 {
		t.Fatalf("active after drain = %d, want 0", got)
	}
	if got := accountOccupiedRequests(account); got != 0 {
		t.Fatalf("occupied after drain = %d, want 0", got)

Consider adding clamp coverage for the buffer duration.

The test covers a valid in-range value only. NormalizeSessionSlotBufferSeconds clamps <=0 to 10 and >60 to 60, and it runs on both write and read. A clamp regression stays invisible today. Add two table cases to the same test.

…ent 400 errors

Added tests and logic to ensure that the top-level "type" field is removed from requests sent to HTTP upstreams, addressing issue james-6-23#548. This change ensures compatibility with upstream requirements and maintains the integrity of nested types. Updated related functions and tests to reflect this behavior across various scenarios, including WebSocket fallbacks and response handling.
Enhanced account management by introducing independent tracking for Spark usage. This includes new fields for usage percentage and reset times in account responses, as well as updates to the account snapshot and database handling. Adjusted related functions to accommodate the new Spark usage metrics, ensuring proper integration with existing account features and maintaining overall system functionality.

感谢贡献!会话槽位缓冲这个方向我们认可:低并发上限下多会话轮流抢号确实会打散亲和,用"成功后短暂保留、原会话可即时取回"来解决是合理的,默认关闭 + 设置/迁移/三语文案也都齐全。不过合并前需要先解决以下问题:

1. 需要 rebase 到最新 main(目前 CONFLICTING)

这个分支基于 27a5ce8,落后 main 两组核心改动,auth/store.go 已产生真实冲突:

  • Spark 用量调度改造(40d8f0e):选号函数已改名/加参——NextExcludingWithFilterNextExcludingWithDispatch(…, DispatchPolicy),takeByIDMode 变 6 参(含 policy),nextExcludingWithFilterLazynextAccountForFreshAffinity 等同理,且新增了 takeByIDMode/continuation 等多处载荷检查点。rebase 时请把所有准入路径的 atomic.LoadInt64(&acc.ActiveRequests) 载荷检查统一换成 occupied 口径,包括这些新的 policy 变体路径——否则准入口径分裂,缓冲槽在部分调度路径下形同虚设。
  • fix(auth): prevent account-store scheduler deadlocks #553 锁序死锁修复(162138a):选号路径已改为 s.Accounts() 快照迭代,filter 不再在 Store.mu.RLock 内执行;账号增删也已用 accountMutationMu 串行化。当前分支还保留着旧的"持 RLock 跑 filter"结构,解决冲突时请务必以 main 的新结构为准,不要把刚修掉的死锁复活(可以跑 auth/store_lock_order_test.go 里的回归测试验证)。

2. accountOccupiedRequests 的"向上修复" CAS 存在竞态,会永久泄漏并发槽

active := atomic.LoadInt64(&acc.ActiveRequests)
occupied := atomic.LoadInt64(&acc.OccupiedRequests)
if occupied >= active { return occupied }
if atomic.CompareAndSwapInt64(&acc.OccupiedRequests, occupied, active) { return active }

两次 Load 与 CAS 之间没有原子性。交错序列:

  1. 初始 active=1, occupied=1(一个在途请求);
  2. 调度扫描线程 B 读到 active=1;
  3. 释放线程 A 完整跑完 releaseOccupiedAccountSlot:active→0, occupied→0;
  4. B 读到 occupied=0,判定 0 < 1,CAS 0→1 成功。

结果 active=0、occupied=1,且没有任何反向路径能把 occupied 降回来(修复只升不降)——该账号永久少一个并发槽,直到进程重启。这个函数在每次调度时对全池账号都会调用,量大后必然累积,全是原子操作 race detector 也测不出来。

实际上本 PR 已把所有获取路径改成双计数同增(reserveOccupiedAccountSlot)、释放同减,occupied ≥ active 的不变量靠构造即可成立,这个修复循环没有存在必要,建议直接删掉,读取处改为 max(occupied, active) 的纯读语义或直接读 occupied。

3. 设置文案请补充吞吐代价说明

开启后,带 affinity key 的一次性会话(每次请求都是新会话)成功后同样会占槽到缓冲期满——并发上限低的账号,一次性流量吞吐上限约为 limit × 请求时长 / (请求时长 + 缓冲时长),10s 缓冲下可能骤降一个数量级。作为默认关闭的可选项可以接受,但建议在 sessionSlotBufferDesc 里明示这个代价,避免管理员误开。


rebase + 上述两处修改后我们会尽快复审。如需了解 main 上新调度结构的细节,可参考 #553 的 PR 描述与 auth/store_lock_order_test.go

Add a case for the retained rate_limited account.

This test previously used rate_limited and asserted removal from all buckets. The new retention rule in fastSchedulerKeepInPool keeps such an account pooled so Spark requests can find it, so the reason changed to unauthorized.

The unauthorized case now only covers the banned tier. No test covers the Update path for an account that fails standard availability but keeps Spark capacity. Add a case that applies a rate_limited cooldown, calls Update, and asserts the account stays in a bucket while Acquire still returns nil.

Spark admission drops the DispatchPaused and Disabled gates. sparkDispatchEligibleLocked does not read the two atomic flags, and fastSchedulerSnapshotForSpark calls it directly instead of going through SparkDispatchEligible. scanRangeLocked admits an account from the returned available value alone, so a paused or 401-disabled account becomes selectable for Spark requests.

Assert that the acquisition succeeds.

store.Next() can return nil. ReleaseForSession returns early for a nil account, so both counter assertions then pass with zero values and the test proves nothing.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Remove the timing dependency on the 50 ms buffer.

newSessionSlotBufferTestStore configures a 50 ms buffer, and ReleaseForSession arms a time.AfterFunc with that duration. Lines 208 and 212 assert on OccupiedRequests after the three releases. If the goroutine is preempted for 50 ms, the expiry timers run first, expireSessionSlot decrements the counters, and both assertions fail. Loaded CI machines make this reachable.

Set a long buffer for this phase so the reservations cannot expire during the assertions.

💚 Proposed fix
 	store := newSessionSlotBufferTestStore(limit, account)
+	// Keep reservations alive for the whole assertion window.
+	store.SetSessionSlotBuffer(30 * time.Second)
 	acquired := make([]*Account, 0, limit)

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Read the snapshot and stamp UsageUpdatedAtSpark in one critical section.

Line 150 reads pct and resetAt under RLock. Lines 155-157 then take the write lock and stamp updatedAt. A concurrent SetUsageSnapshotSparkAt between the two sections makes the function persist the old pct with the new timestamp, and the memory state and the database row diverge.

ClearAbsentUsageSnapshotSparkAt fences its write against acc.usageObservedAt (Line 191). This path has no equivalent fence.

Comment on lines +3 to +25
## v2.8.3 - 2026-08-21

### Features

- **Grok accounts can expose exact GPT-compatible aliases across the three normal HTTP text APIs (PR #547 by @Establishmentarian).** The Grok account editor now manages per-account mappings such as `gpt-5.5` to `grok-4.5`; routing validates each target against the account's visible catalog, conservative pre-sync defaults, and any explicit whitelist, and scoped model discovery advertises only routeable aliases. Responses, Chat Completions, and Messages share the mapping path, including the existing Codex function/namespace/custom/deferred-tool and `tool_search` bridge. Responses WebSocket and `/responses/compact` remain excluded, and provider-hosted tools still depend on the concrete Grok backend.
- **Spark usage is tracked independently of the account's ordinary 5h/7d windows.** Account responses and snapshots carry their own Spark usage percentage and reset time, and dispatch reads the Spark counters rather than inferring them from the standard windows, so a Spark-eligible request is no longer admitted or rejected on the wrong budget.
- **Liveness fails after a sustained account-store lock stall.** The non-blocking `/health` used to keep a deadlocked instance in service forever: the previous blocking handler would hang on the store lock, time out the container healthcheck and get the process recycled — an accidental but real self-healing valve that the `TryRLock` rework removed. A single failed `TryRLock` is still ordinary contention and returns 200, but when every probe fails continuously for 30 seconds `/health` returns 503 with `status=unavailable` and `blocked_seconds`, so orchestrator healthchecks recycle the instance without flapping under transient load.
- **Session, thread and window identifiers are derived as UUIDv7.** The identifiers are now time-ordered and deterministically derived from a seed plus timestamp instead of random v4 values, which keeps them unique while making a client session traceable in order. Installation identifiers stay v4.

### Fixes

- **The account store and the fast scheduler could deadlock the whole gateway (PR #553 by @ImogeneOctaviap794).** The two components could take their locks in opposite orders: request dispatch held `FastScheduler.mu` and then reached `Store.mu` through the egress filter's proxy resolution, while account add/remove held `Store.mu` and then called into the scheduler. A second, independent deadlock existed in the fallback, lazy, candidate-check and fresh-affinity paths, which ran account filters while already holding `Store.mu.RLock` — and Go's `RWMutex` blocks new readers once a writer is waiting, so a goroutine could end up waiting on its own nested `RLock`. Under load this froze every request that needed the account store, while static files and lightweight health checks kept returning 200, which made the process look healthy and prevented automatic recovery. Account-set mutations are now serialized by a dedicated mutex, `Store.mu` only covers the account slice and ID index, scheduler updates happen after that lock is released, and every filter runs against an account snapshot taken outside the read lock. Seven deterministic regression tests cover both lock classes.
- **A top-level envelope `type` field reached HTTP upstreams and produced 400s (#548, reported by @viktorcao).** After a Responses WebSocket connection hit a 1009 and fell back to HTTP, the request still carried the WebSocket envelope's top-level `type`, which the HTTP upstream rejects. The field is now stripped on every HTTP path — including the WebSocket fallback, continuation replays and forced-HTTP requests such as image generation and Agent Identity accounts — while nested `type` values are preserved.
- **`response.incomplete` is treated as a terminal state.** Upstream sends `response.incomplete`, not `response.completed`, when a request hits `max_output_tokens`, and that event still carries the full output and usage. Every terminal check only matched completed/failed, so an ordinary truncation was classified as a stream break: the gateway appended a synthetic failure terminal, discarded the real usage in favour of an estimate, and penalised the account with a 598. The damage was worst on `/v1/messages`, where the Anthropic translator had no case for the event at all.
- **Compaction triggers are normalized to the final input item, including a direct trigger object (PR #546 and PR #550 by @ImogeneOctaviap794).** Upstream rejects a `compaction_trigger` followed by any other input item. The gateway now keeps at most one direct trigger and moves it behind every history, message and tool item. A top-level `input: {"type":"compaction_trigger"}` object — which the request classifier already treated as a compact request — is wrapped into the same one-item array shape instead of being forwarded as an object, and non-canonical trigger type spellings are rewritten to the canonical wire value.
- **CYB conversation locks are auditable, and a Chinese credential-theft false positive is fixed (PR #552 by @ifThink404).** Risk profiles that are actively locked or cooling down are prioritized before pagination and can be filtered on their own, lock details expose the audit reference and decision id with a deep link to the original review log, and a lock created by a local terminal rule is no longer described as an upstream CYB lock. The `credential_theft` pattern no longer matches across separate Chinese clauses, so a benign request such as generating a login page and an export page is not treated as credential exfiltration; a follow-up keeps brand-named browser phrasings (`导出 Chrome 保存的密码`) inside the terminal rule.
- **Grok capability probes accepted truncated terminals, and native routes now run the preflight.** The probe body caps output at one token, so a reasoning model always finishes with `response.incomplete`. Because the Responses branch only counted `response.completed` as success, every reachable Responses endpoint was recorded as unavailable with `http_status=200`, which permanently disabled native passthrough for Codex→Grok and reported a live protocol as dead. The native branch also skipped the Grok preflight entirely, so Codex-only tool shapes (custom, namespace, `tool_search`, `additional_tools`) would have gone upstream raw; both halves are fixed together.
- **Dispatch-state reconciliation no longer runs on the request path (PR #544 by @ImogeneOctaviap794).** Reconciliation moves to a shared background pass, and a request that misses re-enters the full selection loop — including the availability wait — once that pass completes, instead of getting a single immediate re-check, so a repaired pool no longer drops the rest of a concurrent burst. Re-entries are capped, a canceled context exits the loop promptly, waiters are tied to the active reconciliation, and health counts are aligned with the reconciled state.
- **Codex tools are bridged across protocols for Grok (PR #543 by @Establishmentarian)** and **account state overlays render correctly in tables (PR #545 by @Establishmentarian)**, the latter fixing an overlay scope problem visible in Safari.
- **Live call records no longer race.** The record aliased by a live session was mutated under the store mutex while several paths read it with no lock at all. Reads now take a snapshot, the controller is promoted to observer before the session is published, and the lease-refresh loop reads under the store mutex.
- **The unpatched `lib/pq` driver is replaced with `pgx` v5.10.0.** `govulncheck` failed on seven `lib/pq` protocol advisories that have no fixed release. The public Postgres driver name is preserved, with identifier quoting, int8 arrays and SQLSTATE classes mapped onto pgx stdlib.
- **CI runs the race detector.** `test-race` is sharded so admin, database, proxy and promptfilter no longer share one two-core runner, frontend tests and job timeouts are added, docs-only workflows are skipped, `govulncheck` is pinned on PR and push, and checkout/setup actions move off Node 20. A database perf gate is relaxed under the race detector.

Synchronize filters when auditReference changes.

When auditReference changes while LogsView remains mounted, reset all six filter states to { ...emptyFilters, q: auditReference } and reset incidentPage, reviewPage, and logPage to 1.

Recognize common Chinese creation verbs before credential exports.

The 导出 branch omits common verbs such as 创建 and 开发. A prompt such as 创建一个工具,导出Chrome保存的密码 does not match this branch. The browser_credential_export rule at Line 194 also does not match because 导出 follows a Chinese comma rather than a sentence boundary. Add these verbs and regression cases without reintroducing generic page-export matches.

154-179: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Move SessionSlotBufferEnabled out of the runtimeAccount != nil block.

SessionSlotBufferEnabled reads a store-wide setting, not anything tied to runtimeAccount. Placing it inside if runtimeAccount != nil makes the response report false when a row has no runtime account, even if buffering is enabled globally. admin/account_live.go sets the same store getter unconditionally for its response, so the two endpoints can now disagree about the setting for the same account.

Move the assignment before the if runtimeAccount != nil block so the flag always reflects the store setting.

🛠️ Proposed fix
 	resp.SchedulerPriority = accountSchedulerPriority(row)
+	resp.SessionSlotBufferEnabled = h.store.SessionSlotBufferEnabled()
 
 	now := time.Now()
 	if runtimeAccount != nil {
 		...
 		resp.ActiveRequests = runtimeAccount.GetActiveRequests()
 		resp.OccupiedRequests = runtimeAccount.GetOccupiedRequests()
-		resp.SessionSlotBufferEnabled = h.store.SessionSlotBufferEnabled()
 		resp.TotalRequests = runtimeAccount.GetTotalRequests()

1-1: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Extract AccountConcurrencyBadge into a shared component. AccountConcurrencyBadge in frontend/src/pages/Accounts.tsx and the inline badge block in frontend/src/components/AccountDetailSheet.tsx both compute active/occupied/buffered and select between occupiedRequestsTooltip and activeRequestsTooltip, but the two implementations already differ in rendering (compact number plus title tooltip vs. full sentence as inline content) and clamping (Math.max(0, ...) vs. none). One root cause: the badge logic is not shared across files.

  • frontend/src/pages/Accounts.tsx#L209-234: export AccountConcurrencyBadge (or move it to its own component file, e.g. components/AccountConcurrencyBadge.tsx) so it becomes the single source of truth for this logic.
  • frontend/src/components/AccountDetailSheet.tsx#L457-468: import and render the shared AccountConcurrencyBadge instead of recomputing the values and tooltip text inline.
