Code Review
本次 PR 主要修复了 Gemini API 在透传（passthrough）模式下未追踪成本、Token 用量等统计信息的 Bug。修复方案通过引入后台任务来处理响应并记录统计数据，同时不阻塞客户端，覆盖了流式和非流式两种场景，这是一个很好的改进。此外，SQL 迁移脚本也得到了增强，通过使用 IF NOT EXISTS 和将 daily_reset_mode 列转换为 ENUM 类型，提升了脚本的健壮性和数据完整性。
然而，response-handler.ts 中的修改引入了大量重复的统计逻辑代码。我建议将其重构为一个共享的辅助方法以提高代码的可维护性。另外，我发现在流式透传的处理逻辑中，缺少了存储响应体的调用。在 SQL 迁移脚本中，我也建议使用 time 数据类型代替 varchar 来存储 daily_reset_time，以进一步增强数据完整性。
| ALTER TABLE "providers" ADD COLUMN "daily_reset_time" varchar(5) DEFAULT '00:00';--> statement-breakpoint | ||
| ALTER TABLE "providers" ADD COLUMN "daily_reset_mode" varchar(10) DEFAULT 'fixed' NOT NULL;--> statement-breakpoint | ||
| ALTER TABLE "keys" ADD COLUMN IF NOT EXISTS "limit_daily_usd" numeric(10, 2);--> statement-breakpoint | ||
| ALTER TABLE "keys" ADD COLUMN IF NOT EXISTS "daily_reset_time" varchar(5) DEFAULT '00:00';--> statement-breakpoint |

为了增强数据完整性，建议将 daily_reset_time 列的类型从 varchar(5) 更改为 time(0) without time zone。使用 time 类型可以确保该列只存储有效的时间格式（如 '00:00'），并能利用数据库内置的时间函数进行操作和校验，防止存入 'abcde' 等无效数据。

同上，为了增强数据完整性，建议将 daily_reset_time 列的类型从 varchar(5) 更改为 time(0) without time zone。这可以保证数据格式的正确性，并利用数据库对时间类型的原生支持。

这部分统计逻辑（计算耗时、更新成本、追踪 tokens 等）在 handleNonStream 的 Gemini 透传、handleStream 的 Gemini 透传以及非 Gemini 场景下存在大量重复。这种重复使得代码难以维护，未来对统计逻辑的任何修改都需要在多个地方同步更新。
建议将这块通用逻辑提取到一个私有的静态辅助方法中，例如 _finalizeRequestStats。
private static async _finalizeRequestStats(
session: ProxySession,
responseText: string,
statusCode: number,
duration: number
): Promise<void> {
const { messageContext, provider } = session;
if (!provider || !messageContext) {
return;
}
// 结束请求状态追踪
ProxyStatusTracker.getInstance().endRequest(messageContext.user.id, messageContext.id);
// 更新请求时长
await updateMessageRequestDuration(messageContext.id, duration);
const { usageMetrics } = parseUsageFromResponseText(
responseText,
provider.providerType
);
if (!usageMetrics) {
// 即使没有 usageMetrics，也需要更新状态码和 provider chain
await updateMessageRequestDetails(messageContext.id, {
statusCode: statusCode,
providerChain: session.getProviderChain(),
});
return;
}
// 更新成本和 tokens
await updateRequestCostFromUsage(
messageContext.id,
session.getOriginalModel(),
session.getCurrentModel(),
usageMetrics,
provider.costMultiplier
);
await trackCostToRedis(session, usageMetrics);
// 更新 session usage
if (session.sessionId) {
let costUsdStr: string | undefined;
if (session.request.model) {
const priceData = await findLatestPriceByModel(session.request.model);
if (priceData?.priceData) {
const cost = calculateRequestCost(
usageMetrics,
priceData.priceData,
provider.costMultiplier
);
if (cost.gt(0)) {
costUsdStr = cost.toString();
}
}
}
void SessionManager.updateSessionUsage(session.sessionId, {
inputTokens: usageMetrics.input_tokens,
outputTokens: usageMetrics.output_tokens,
cacheCreationInputTokens: usageMetrics.cache_creation_input_tokens,
cacheReadInputTokens: usageMetrics.cache_read_input_tokens,
costUsd: costUsdStr,
status: statusCode >= 200 && statusCode < 300 ? "completed" : "error",
statusCode: statusCode,
}).catch((error: unknown) => {
logger.error("[ResponseHandler] Failed to update session usage:", error);
});
}
// 更新请求详情
await updateMessageRequestDetails(messageContext.id, {
statusCode: statusCode,
inputTokens: usageMetrics?.input_tokens,
outputTokens: usageMetrics?.output_tokens,
cacheCreationInputTokens: usageMetrics?.cache_creation_input_tokens,
cacheReadInputTokens: usageMetrics?.cache_read_input_tokens,
providerChain: session.getProviderChain(),
});
}这样，各个处理分支就可以简化为调用此方法，从而消除重复代码，提高可维护性。

在流式透传模式下，统计任务中缺少了对完整响应体 allContent 的存储。为了与其他处理逻辑保持一致并支持后续的日志追溯，建议在此处添加 SessionManager.storeSessionResponse 调用，将完整的响应内容存入 Redis。

| const allContent = chunks.join(""); | |
| // 存储响应体到 Redis（5分钟过期） | |

🟠 Resource leak: clearResponseTimeout not called in error path
Why this is a problem: In the Gemini passthrough logic (lines 71-112), clearResponseTimeout() is called inside the try block. If responseForStats.text() fails or any error occurs before line 101, the timeout is never cleared, causing a resource leak and potential memory issues.
Suggested fix:
const statsPromise = (async () => {
try {
const responseText = await responseForStats.text();
if (session.sessionId) {
void SessionManager.storeSessionResponse(session.sessionId, responseText).catch(
(err) => logger.error("[ResponseHandler] Failed to store response:", err)
);
}
const duration = Date.now() - session.startTime;
await finalizeRequestStats(session, responseText, statusCode, duration);
} catch (error) {
if (!isClientAbortError(error as Error)) {
logger.error("[ResponseHandler] Gemini non-stream passthrough stats task failed:", error);
}
} finally {
// Move cleanup to finally block to ensure it always runs
const sessionWithCleanup = session as typeof session & {
clearResponseTimeout?: () => void;
};
if (sessionWithCleanup.clearResponseTimeout) {
sessionWithCleanup.clearResponseTimeout();
}
AsyncTaskManager.cleanup(taskId);
}
})();

🟡 Semantically incorrect status code for upstream abort
Why this is a problem: At line 959, when detecting upstream abort (!clientAborted), the code uses status 524 (Cloudflare-specific "A Timeout Occurred"). However, this scenario represents an upstream server closing the connection unexpectedly, not a timeout. The correct HTTP status code should be 502 (Bad Gateway) for upstream failures.
Why this matters:
- Status 524 is Cloudflare-specific and not a standard HTTP code
- It semantically indicates a timeout, not an upstream abort
- Using 502 provides better clarity for monitoring and debugging
Suggested fix:
} else if (!clientAborted) {
// 上游在流式过程中意外中断：视为供应商/网络错误
logger.error("ResponseHandler: Upstream stream aborted unexpectedly", {
taskId,
providerId: provider.id,
providerName: provider.name,
messageId: messageContext.id,
chunksCollected: chunks.length,
errorName: err.name,
errorMessage: err.message || "(empty message)",
});
await persistRequestFailure({
session,
messageContext,
statusCode: statusCode && statusCode >= 400 ? statusCode : 502, // Changed from 524 to 502
error: err,
taskId,
phase: "stream",
});
}

🟡 SQL migration may fail with invalid existing data
Why this is a problem: The type conversion at lines 36-43 uses USING clause to cast varchar to enum, but assumes all existing values are valid ('fixed' or 'rolling'). If any row has an invalid value (e.g., from manual insertion or corruption), the migration will fail with a cryptic error, potentially blocking deployments.
Suggested fix:
-- Step 3.0: Validate existing data before conversion
DO $$
DECLARE
invalid_count INTEGER;
BEGIN
SELECT COUNT(*) INTO invalid_count
FROM "keys"
WHERE "daily_reset_mode" NOT IN ('fixed', 'rolling');
IF invalid_count > 0 THEN
RAISE EXCEPTION 'Found % invalid daily_reset_mode values in keys table. Valid values are: fixed, rolling', invalid_count;
END IF;
SELECT COUNT(*) INTO invalid_count
FROM "providers"
WHERE "daily_reset_mode" NOT IN ('fixed', 'rolling');
IF invalid_count > 0 THEN
RAISE EXCEPTION 'Found % invalid daily_reset_mode values in providers table. Valid values are: fixed, rolling', invalid_count;
END IF;
END $$;
--> statement-breakpoint
-- Step 3.1: Safe type conversion (only if validation passed)
ALTER TABLE "keys"
ALTER COLUMN "daily_reset_mode" TYPE "daily_reset_mode"
USING "daily_reset_mode"::"daily_reset_mode";
--> statement-breakpoint
ALTER TABLE "providers"
ALTER COLUMN "daily_reset_mode" TYPE "daily_reset_mode"
USING "daily_reset_mode"::"daily_reset_mode";

🟡 Insufficient error differentiation in abort detection
Why this is a problem: The new upstream abort detection (lines 877-968) catches all AbortErrors when !clientAborted, but doesn't differentiate between:
- Upstream server closing connection unexpectedly
- Network errors (DNS failure, connection refused, etc.)
- Other abort sources
This makes debugging and monitoring harder, as all these different failure modes are logged identically as "Upstream stream aborted unexpectedly".
Suggested fix:
const sessionWithController = session as typeof session & {
responseController?: AbortController;
};
const clientAborted = session.clientAbortSignal?.aborted ?? false;
const isResponseControllerAborted =
sessionWithController.responseController?.signal.aborted ?? false;
if (isClientAbortError(err)) {
const isResponseTimeout = isResponseControllerAborted && !clientAborted;
const isIdleTimeout = err.message?.includes("streaming_idle");
if (isResponseTimeout && !isIdleTimeout) {
// ... existing timeout handling ...
} else if (isIdleTimeout) {
// ... existing idle timeout handling ...
} else if (!clientAborted) {
// More granular error detection
const isNetworkError = err.message?.includes('fetch failed') ||
err.message?.includes('ECONNREFUSED') ||
err.message?.includes('ENOTFOUND');
const isUpstreamClose = err.name === 'AbortError' && !isResponseControllerAborted;
if (isNetworkError) {
logger.error("ResponseHandler: Network error during streaming", {
taskId, providerId: provider.id, messageId: messageContext.id,
errorMessage: err.message, errorType: "network"
});
} else if (isUpstreamClose) {
logger.error("ResponseHandler: Upstream closed connection", {
taskId, providerId: provider.id, messageId: messageContext.id,
errorType: "upstream_close"
});
} else {
logger.error("ResponseHandler: Unknown abort reason", {
taskId, providerId: provider.id, messageId: messageContext.id,
errorName: err.name, errorMessage: err.message, errorType: "unknown"
});
}
await persistRequestFailure({
session, messageContext,
statusCode: 502,
error: err, taskId, phase: "stream",
});
}
}

📋 Code Review Summary
This PR fixes an infinite loop in leaderboard tab switching (#178) and improves the database migration for daily cost limits. The leaderboard fix is correct, but the response handler changes introduce potential resource leaks and use semantically incorrect HTTP status codes.
🔍 Issues Found
- Critical (🔴): 0 issues
- High (🟠): 1 issue
- Medium (🟡): 3 issues
- Low (🟢): 0 issues
🎯 Priority Actions
-
Fix resource leak in Gemini passthrough (🟠 High): Move
clearResponseTimeout()to finally block to ensure cleanup happens even when errors occur (lines 71-112 and similar pattern in stream handler) -
Correct HTTP status code for upstream aborts (🟡 Medium): Change status 524 to 502 for upstream connection failures at line 959 - 524 is Cloudflare-specific and semantically incorrect
-
Add SQL migration validation (🟡 Medium): Validate existing data before enum type conversion to prevent migration failures from invalid varchar values
-
Improve error differentiation (🟡 Medium): Add more granular detection for network errors vs upstream closes vs other abort types for better monitoring
💡 General Observations
Positive changes:
- Leaderboard infinite loop fix is clean and well-documented
- SQL migration improvements with
IF NOT EXISTSclauses increase idempotency - Enum type creation with exception handling is a good defensive pattern
Areas of concern:
- The Gemini passthrough implementation has the same resource leak pattern in both stream and non-stream paths
- Status code inconsistencies across error paths (524 vs 502 vs 500) make monitoring and debugging harder
- Error handling consolidation is good, but loses some granularity in distinguishing failure modes
🤖 Automated review by Claude AI - focused on identifying issues for improvement
- Changed status code from 524 (Cloudflare-specific) to 502 (RFC 7231) for three scenarios: 1. Non-stream response timeout during body read (line 383) 2. Stream response timeout during body read (line 926) 3. Streaming idle timeout (line 962) - Rationale: * 524 is Cloudflare-specific and semantically incorrect (indicates timeout waiting for response headers) * 502 Bad Gateway correctly represents incomplete/interrupted upstream responses * Aligns with existing code at line 982 which already uses 502 for upstream abort * Improves HTTP RFC compliance and monitoring clarity - Impact: Better monitoring, clearer error semantics, consistent with standard HTTP codes
- 移除用户列表高度限制，支持完整显示所有用户 - 将新增用户按钮移至列表顶部，提升可见性 - 添加精心设计的空状态引导，帮助新用户快速上手 - 完善 5 种语言的国际化支持（en, ja, ru, zh-CN, zh-TW） 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
