32-33: 属性类型错误：Coroutine::create 返回 int|false，声明为 ?Coroutine 将在赋值时报 TypeError
Hyperf\Engine\Coroutine::create()返回协程 ID（int）或 false；当前把其赋给?Coroutine会触发类型错误。建议改为?int，并将 false 转为 null。- protected ?Coroutine $waitingWorkerExit = null; + protected ?int $waitingWorkerExit = null;- $this->waitingWorkerExit ??= Coroutine::create(function () { + $this->waitingWorkerExit ??= (Coroutine::create(function () { try { CoordinatorManager::until(Constants::WORKER_EXIT)->yield(); $this->close(); $this->workerExited = true; } catch (Throwable) { } - }); + }) ?: null);Also applies to: 104-106

51-56: 修复静默丢包并避免阻塞：worker 已退出或 push 失败时回退为同步发送，并为 push 设置短超时当前在 worker 退出或通道尚未/已被关闭时，
$this->chan?->push(...)会成为空操作，仍返回 202，导致请求被悄然丢弃；同时无超时的push可能在高压下阻塞请求路径。建议如下修改：public function sendRequest(Request $request, Options $options): Response { - // Start the loop if not started yet - $this->loop(); - - // Push the request to the channel - $this->chan?->push([$request, $options]); + // 启动消费循环 + $this->loop(); + + // worker 已退出或通道不可用时，回退为同步发送，避免静默丢包 + if ($this->workerExited || ! $this->chan) { + return parent::sendRequest($request, $options); + } + + // 带极短超时的 push；失败则回退为同步发送 + if ($this->chan->push([$request, $options], 0.001) === false) { + return parent::sendRequest($request, $options); + } return new Response(202, ['X-Sentry-Request-Status' => ['Queued']], ''); }
84-89: 在子协程内捕获 parent::sendRequest 异常，并配合 WaitGroup 标记完成未捕获的异常会污染日志且可能占用并发槽位；同时补充 WaitGroup 记账，确保 close 时可等待收敛。

78-96: 双层 while + break 2 容易造成控制流复杂与潜在自旋，建议合并为单循环逻辑等价且更易读，也避免
catch后简单break只跳出内层循环导致外层空转。- try { - while (true) { - while (true) { - if ($chan->isClosing() || ! $params = $chan->pop()) { - break 2; - } - try { - // 调度... - } catch (Throwable) { - break; - } finally { - $params = null; - } - } - } + try { + while (! $chan->isClosing() && ($params = $chan->pop())) { + try { + // 调度... + } catch (Throwable) { + // 记录后继续消费下一条，避免提前退出 + continue; + } finally { + $params = null; + } + } } catch (Throwable $e) {
97-101: 不要吞掉异常：至少输出一次性错误空的
catch会隐藏真实问题，排障困难。最低限度记录错误（或注入 Logger）。- } catch (Throwable $e) { - } finally { + } catch (Throwable $e) { + error_log(sprintf('[Sentry HttpClient] worker loop crashed: %s', (string) $e)); + } finally { $this->close(); }如需，我可以补一版基于

49-58: 请求可能在 worker 退出或 channel 关闭时静默丢失当
workerExited为 true 时，loop()会直接返回导致$this->chan保持为 null，此时$this->chan?->push()会成为空操作但仍返回 202 状态码，造成请求静默丢失。另外，当 Channel 满时push()会阻塞。建议添加超时和回退机制：
public function sendRequest(Request $request, Options $options): Response { // Start the loop if not started yet $this->loop(); + // Worker 已退出时直接同步发送 + if ($this->workerExited) { + return parent::sendRequest($request, $options); + } + - // Push the request to the channel - $this->chan?->push(func_get_args()); + // Push 到队列，设置短超时避免阻塞 + if (! $this->chan || $this->chan->push(func_get_args(), 0.001) === false) { + // 队列不可用或超时，回退为同步发送 + return parent::sendRequest($request, $options); + } return new Response(202, ['X-Sentry-Request-Status' => ['Queued']], ''); }
60-64: 关闭 Channel 前未等待并发任务完成
close()方法仅关闭 Channel 但未等待进行中的并发请求完成，可能导致尾部请求被截断。建议使用 WaitGroup 跟踪并等待任务：
+use Hyperf\Coroutine\WaitGroup; class HttpClient extends \Sentry\HttpClient\HttpClient { protected ?Channel $chan = null; protected ?Concurrent $concurrent = null; + protected ?WaitGroup $wg = null; public function __construct( string $sdkIdentifier, string $sdkVersion, protected int $channelSize = 65535, int $concurrentLimit = 1000, ) { parent::__construct($sdkIdentifier, $sdkVersion); + $this->wg = new WaitGroup(); if ($concurrentLimit > 0) { $this->concurrent = new Concurrent($concurrentLimit); } } public function close(): void { + // 等待进行中的任务完成（最多等待 100ms） + $this->wg?->wait(0.1); $this->chan?->close(); $this->chan = null; }并在派发任务时调用
$this->wg->add()和$this->wg->done()。
94-104: 未捕获的异常可能污染日志或中断并发槽位
parent::sendRequest()调用可能抛出异常，在协程内未被捕获会成为未处理异常。建议在协程内部捕获异常：
try { - $closure = fn () => parent::sendRequest(...$args); + $closure = function () use ($args) { + try { + return parent::sendRequest(...$args); + } catch (Throwable $e) { + // 记录错误但不中断其他请求 + // TODO: 添加日志记录 + } + }; if ($this->concurrent) { $this->concurrent->create($closure); } else { Coroutine::create($closure); }

75-82: 保留了注释掉的调试代码这段注释掉的内存监控代码可以移除，或者考虑通过配置开关来控制是否启用调试模式。
建议完全移除或改为可配置的调试模式：
- // Dump memory usage and channel size - // Coroutine::create(function () use ($chan) { - // while (! $chan->isClosing()) { - // dump('Memory Usage(MB): ' . memory_get_usage(true) / 1024 / 1024); - // dump('Channel Size: ' . $chan->getLength()); - // sleep(1); - // } - // }); + // 如需调试，可通过环境变量启用监控 + if ((bool) env('SENTRY_DEBUG_MODE', false)) { + Coroutine::create(function () use ($chan) { + while (! $chan->isClosing()) { + // 使用日志而非 dump + $this->logger?->debug('Sentry HttpClient stats', [ + 'memory_mb' => memory_get_usage(true) / 1024 / 1024, + 'channel_size' => $chan->getLength(), + ]); + sleep(1); + } + }); + }
88-92: 类型注解与实际使用不匹配虽然 PR 描述提到使用
array{0:Request,1:Options}类型，但func_get_args()返回的是普通数组，且pop()可能返回false或null。建议使用更精确的数组构造：
- $this->chan?->push(func_get_args()); + $this->chan?->push([$request, $options]);并在处理时添加类型检查：
- if ($chan->isClosing() || ! $args = $chan->pop()) { + if ($chan->isClosing() || ! ($args = $chan->pop()) || ! is_array($args)) { break 2; } + // 验证参数结构 + if (count($args) !== 2 || ! $args[0] instanceof Request || ! $args[1] instanceof Options) { + continue; + }

51-57: 避免静默丢包与请求路径阻塞：push 需带超时并在失败/已退出时回退同步发送。
- worker 已退出时
$this->chan为 null，当前实现会直接“空推送”但仍返回 202，导致事件丢弃。- 队列满时
push()会阻塞请求线程，需设置极短超时并回退到同步发送。建议改动：
- // Start the loop if not started yet - $this->loop(); - - // Push the request to the channel - $this->chan?->push(func_get_args()); - - return new Response(202, ['X-Sentry-Request-Status' => ['Queued']], ''); + // Start the loop if not started yet + $this->loop(); + + // Worker 已退出或 Channel 不可用时，回退同步发送，避免静默丢包 + if ($this->workerExited) { + return parent::sendRequest($request, $options); + } + + $payload = [$request, $options]; + $chan = $this->chan; + + // 带极短超时；失败（超时/已关闭）则回退同步发送 + if (! $chan || $chan->push($payload, 0.001) === false) { + return parent::sendRequest($request, $options); + } + + return new Response(202, ['X-Sentry-Request-Status' => ['Queued']], '');
60-64: close() 未等待在途任务完成，易“丢尾”。仅关闭 Channel 不等于并发任务完成；建议在 close 前对在途任务做短暂收敛等待（如 100ms，可配置）。
public function close(): void { - $this->chan?->close(); - $this->chan = null; + // 短暂等待在途任务收敛，避免尾部请求未完成即退出 + if (isset($this->wg)) { + $this->wg->wait(0.1); + } + $this->chan?->close(); + $this->chan = null; }为支撑上述修改，需要在类中增加 WaitGroup（见下方补充代码）。

68-71: worker 已退出时 loop 提前返回会导致 sendRequest 静默丢包你在
sendRequest()中未判断该状态且仍返回 202，已在上文建议中通过“回退同步发送”修复。可在压测中验证：强制触发
WORKER_EXIT后，继续发送若干请求，确保无 202 且未真正发送的情况。
54-57: 避免静默丢包与阻塞：为 push 增加超时并在失败时回退同步发送，同时避免 func_get_args()
- 当前
?->push()在$this->chan === null时直接空操作且仍返回 202，导致“无声丢包”。Channel::push满载时会阻塞调用路径，建议增加极短超时，失败则回退parent::sendRequest(...)。- 建议用显式数组
[$request, $options]，与声明的array{0:Request,1:Options}更一致，便于静态分析。public function sendRequest(Request $request, Options $options): Response { // Start the loop if not started yet $this->loop(); - // Push the request to the channel - $this->chan?->push(func_get_args()); + // worker 已退出：回退为同步发送，避免丢包 + if ($this->workerExited) { + return parent::sendRequest($request, $options); + } + + // Push 到队列；不存在/已关闭/超时则回退为同步发送 + $chan = $this->chan; + if (! $chan || $chan->push([$request, $options], 0.001) === false) { + return parent::sendRequest($request, $options); + } return new Response(202, ['X-Sentry-Request-Status' => ['Queued']], ''); }
60-64: close() 未等待在途任务完成，存在“尾部丢单”风险建议用 WaitGroup 统计/等待已派发协程，带上短超时后再关闭 Channel。
示例（仅示意，需在类中补充属性与初始化）：
+use Hyperf\Coroutine\WaitGroup; ... - public function close(): void + public function close(): void { - $this->chan?->close(); + // 等待在途任务短暂收敛（示例 100ms） + $this->wg?->wait(0.1); + $this->chan?->close(); $this->chan = null; }派发处（见下条评论中的 diff）在创建子协程前
add(1)，子协程finally中done()。
94-99: 子协程内未捕获的异常会污染日志并占用并发槽位在
$callable内部捕获Throwable，记录日志或吞掉。- $callable = fn () => parent::sendRequest(...$args); + $callable = function () use ($args) { + try { + parent::sendRequest(...$args); + } catch (\Throwable $e) { + // TODO: 注入 logger 后记录到 error 级别，避免静默。 + } + };

32-33: 致命：属性类型与 Coroutine::create 返回值不匹配，将触发类型错误
Coroutine::create()返回int|false，但$waitingWorkerExit被声明为?Coroutine并被赋值为Coroutine::create(...)的返回值，这会在运行时抛出TypeError。建议用布尔哨兵或存协程 ID。- protected ?Coroutine $waitingWorkerExit = null; + // 仅作“是否已启动等待协程”的哨兵位 + protected bool $waitingWorkerExitStarted = false; @@ - $this->waitingWorkerExit ??= Coroutine::create(function () { + if (! $this->waitingWorkerExitStarted) { + Coroutine::create(function () { try { CoordinatorManager::until(Constants::WORKER_EXIT)->yield(); $this->close(); $this->workerExited = true; } catch (Throwable) { } - }); + }); + $this->waitingWorkerExitStarted = true; + }Also applies to: 111-118

51-57: 修复：避免在 worker 已退出/通道关闭/队列已满时静默丢包；push 应加超时并回退同步发送当前
push无返回值检查且workerExited时仍返回 202，事件会被悄然丢弃。建议：
- 若
workerExited为 true 或chan不可用/push失败（含关闭或超时），直接回退parent::sendRequest()。- 为
push设置极短超时，避免在热点路径阻塞。public function sendRequest(Request $request, Options $options): Response { // Start the loop if not started yet $this->loop(); - // Push the request to the channel - $chan = $this->chan; - $chan?->push([$request, $options]); + // worker 已退出或通道不可用/超时 -> 同步发送，避免丢包或阻塞 + if ($this->workerExited) { + return parent::sendRequest($request, $options); + } + $chan = $this->chan; + if (! $chan || $chan->push([$request, $options], 0.001) === false) { + return parent::sendRequest($request, $options); + } return new Response(202, ['X-Sentry-Request-Status' => ['Queued']], ''); }若需要，我可将超时阈值做成可配置参数（如
$this->pushTimeout）。请确认 Hyperf Engine
Channel::push的超时参数与返回值（true/false）行为与当前版本一致：Hyperf Engine Channel::push 是否支持超时参数？关闭或超时时返回值是什么？
88-96: 子协程内未捕获异常，可能污染日志/打断并发槽位；建议包装 callable 捕获异常
parent::sendRequest(...$args)若抛异常将在子协程内未被捕获。建议在callable内部 try/catch，必要时记录日志。- try { - $callable = fn () => parent::sendRequest(...$args); + try { + $callable = function () use ($args) { + try { + parent::sendRequest(...$args); + } catch (Throwable $e) { + // TODO: 根据项目日志方案记录错误，例如： + // $this->logger?->error('Sentry async send failed', ['exception' => $e]); + } + }; if ($this->concurrent) { $this->concurrent->create($callable); } else { Coroutine::create($callable); }

24-25: 引入 tap() 没问题可读性更好，且便于在初始化时附带副作用。
63-67: 早退守卫合理，但需与 sendRequest 回退逻辑配套
workerExited的早退能避免无意义初始化；配合上条修改，确保此状态下请求走同步发送而非返回 202。
121-129: 保留 public close()（或提供兼容 public 代理）并在关闭前等待在途任务收敛
- 兼容性：src/sentry/src/HttpClient/HttpClient.php 中 close() 目前为 protected；仓库内未发现外部对该类实例调用 ->close()，但若历史版本或外部用户依赖 public close()，降级为 protected 会造成破坏性变更。恢复为 public 或新增 public 代理（例如 public function close(int $timeoutMs = 100): void）以维持 BC。
- 并发完整性：当前 close() 仅 close Channel，不等待正在执行的并发任务（Concurrent/Coroutine），可能导致未完成的“尾部请求”被中断。建议在派发任务前使用 WaitGroup->add(1)，任务结束时 done()，并在 close()/代理中通过 WaitGroup->wait(timeout) 做短时收敛（或提供可配置的 drain/closeWithTimeout API）。

51-58: 避免静默丢包与热点路径阻塞：push 需带超时，且失败/已退出时回退同步发送。当 worker 已退出或通道满/关闭时，当前实现仍返回 202，导致请求被悄然丢弃；且无超时会在高负载下阻塞请求线程。
应用下面的补丁到 sendRequest 以修复：
public function sendRequest(Request $request, Options $options): Response { // Start the loop if not started yet $this->loop(); - // Push the request to the channel - $chan = $this->chan; - $chan?->push([$request, $options]); + // worker 已退出或队列不可用时回退为同步发送；push 使用极短超时避免阻塞 + if ($this->workerExited) { + return parent::sendRequest($request, $options); + } + + $chan = $this->chan; + if (! $chan || $chan->push([$request, $options], 0.001) === false) { + // 可选：依据 $chan?->errCode 记录 SWOOLE_CHANNEL_TIMEOUT / SWOOLE_CHANNEL_CLOSED + return parent::sendRequest($request, $options); + } return new Response(202, ['X-Sentry-Request-Status' => ['Queued']], ''); }Also applies to: 63-67
82-101: 简化双层 while 并显式 pop 判定，提升可读性与健壮性。当前
break 2/! $args = $chan->pop()判定不直观。可合并为单循环并使用!== false明确区分失败与空数组。应用此补丁：
- try { - while (true) { - while (true) { - // If the channel is closing or pop failed, exit the loop - if ($chan->isClosing() || ! $args = $chan->pop()) { - break 2; - } - try { - $callable = fn () => parent::sendRequest(...$args); - if ($this->concurrent) { - $this->concurrent->create($callable); - } else { - Coroutine::create($callable); - } - } catch (Throwable) { - break; - } finally { - $callable = null; - $args = null; - } - } - } + try { + while (! $chan->isClosing() && ($args = $chan->pop()) !== false) { + try { + $callable = fn () => parent::sendRequest(...$args); + if ($this->concurrent) { + $this->concurrent->create($callable); + } else { + Coroutine::create($callable); + } + } catch (Throwable) { + // 调度失败：跳过当前消息，继续 + continue; + } finally { + $callable = null; + $args = null; + } + }
88-96: 在子协程内捕获 parent::sendRequest 异常，并配合 WaitGroup 统计在途任务，close 前短暂等待收敛。避免未捕获异常污染日志或占用并发槽位；同时在关闭前等待短时间避免“尾部丢单”。
应用此补丁为派发处加计数并在 callable 内 done；同时在
close()里等待收敛（需搭配下方“额外变更”）：- try { - $callable = fn () => parent::sendRequest(...$args); + try { + if ($this->wg) { $this->wg->add(1); } + $callable = function () use ($args) { + try { + parent::sendRequest(...$args); + } catch (Throwable $e) { + // TODO: 记录日志或打点 + } finally { + $this->wg?->done(); + } + }; if ($this->concurrent) { $this->concurrent->create($callable); } else { Coroutine::create($callable); } } catch (Throwable) { break;并在
close()中增加短暂等待（100ms 仅示例，可配为可调）：public function close(): void { - $chan = $this->chan; + $this->wg?->wait(0.1); + $chan = $this->chan; $chan?->close();额外变更（不在上述选定行内）：
// 顶部增加 use Hyperf\Coroutine\WaitGroup; // 类属性中增加 protected ?WaitGroup $wg = null; // 构造函数中初始化 $this->wg = new WaitGroup();

103-107: finally 内重复关闭通道，保留一次即可。
$chan->close()与$this->close()都会关闭通道；重复关闭无益且增加竞态复杂度。- } finally { - $chan->close(); - $this->close(); - } + } finally { + $this->close(); + }
85-86: 判定表达式建议加括号，避免运算符优先级歧义。若不采纳单循环重构，至少改为显式
($args = $chan->pop()) === false。- if ($chan->isClosing() || ! $args = $chan->pop()) { + if ($chan->isClosing() || ($args = $chan->pop()) === false) {

代码审查报告
🎯 变更总结
- 内存优化：将
Closure对象替换为数组参数[$request, $options]，减少内存开销 - 资源清理：改进了参数清理逻辑，在
finally块中显式设置$callable和$args为null - 代码重构：使用
tap函数简化通道初始化逻辑，提高代码可读性 - 方法可见性：将
close()方法从public改为protected - 注释改进：添加了更清晰的注释说明代码逻辑
⚠️ 潜在风险
- 破坏性变更：
close()方法可见性从public变为protected，可能影响外部直接调用此方法的代码 - 嵌套循环：新增了双重
while(true)循环结构，虽然有break 2跳出，但逻辑复杂度增加 - 内存泄漏风险：虽然添加了显式的
null赋值，但在高并发场景下仍需验证是否完全解决内存泄漏问题 - 异常处理：外层
catch (Throwable $e)捕获异常但未记录日志，可能导致错误难以追踪
💡 优化建议
-
日志记录：建议在异常捕获处添加日志记录
} catch (Throwable $e) { // 建议添加日志记录 logger()->error('HttpClient loop error: ' . $e->getMessage()); }
-
简化循环结构：考虑将双重 while 循环简化为单层循环，提高代码可读性
-
添加单元测试：针对内存优化和资源清理逻辑增加相应的测试用例
-
性能监控：建议保留被注释的内存监控代码作为调试选项，或提供配置开关
✅ 合规性检查
- ✅ 代码风格：符合 PSR-12 标准，导入语句按字母排序
- ✅ 命名规范：变量和方法命名清晰，符合项目惯例
- ✅ 类型声明：正确使用了 PHP 8+ 的类型声明特性
- ✅ 注释规范：添加的注释简洁明了，提高了代码可维护性
⚠️ 向后兼容：close()方法可见性变更可能影响向后兼容性
📝 总体评价
这个 PR 在内存优化和代码可读性方面有显著改进。主要优化了内存使用，通过将 Closure 替换为数组参数减少了内存开销。代码重构合理，使用了现代 PHP 特性。建议在合并前确认 close() 方法可见性变更的影响范围。

47-56: 避免静默丢单与热路径阻塞：push 未检查返回值，worker 退出时仍返回 202
- 当 worker 已退出或通道已关闭/不存在时，
$chan?->push()什么也不做却仍返回 202，导致请求被悄然丢弃。- 未设置 push 超时，通道已满时会阻塞业务请求线程。
建议：在 push 前后增加短超时与回退到同步发送；若 worker 已退出或 push 失败（超时/关闭），直接走
parent::sendRequest(...)。public function sendRequest(Request $request, Options $options): Response { // Start the loop if not started yet $this->loop(); - // Push the request to the channel - $chan = $this->chan; - $chan?->push([$request, $options]); + // worker 已退出或队列不可用/已关闭/超时 -> 回退为同步发送，避免静默丢单 + if ($this->workerExited) { + return parent::sendRequest($request, $options); + } + $chan = $this->chan; + if (! $chan || $chan->push([$request, $options], 0.002) === false) { + // 可选：基于 $chan->errCode 区分 CLOSED / TIMEOUT + return parent::sendRequest($request, $options); + } return new Response(202, ['X-Sentry-Request-Status' => ['Queued']], ''); }

break容易读错控制流；catch(Throwable){ break; }仅跳出内层循环，外层继续，存在忙等风险。建议改为单循环并用($args = $chan->pop()) !== false显式判断。- try { - while (true) { - while (true) { - // If the channel is closing or pop failed, exit the loop - if (! $args = $this->chan?->pop()) { - break 2; - } - try { - $callable = fn () => parent::sendRequest(...$args); - if ($this->concurrent) { - $this->concurrent->create($callable); - } else { - Coroutine::create($callable); - } - } catch (Throwable) { - break; - } finally { - $callable = null; - $args = null; - } - } - } - } catch (Throwable $e) { - } finally { - $this->close(); - } + try { + $chan = $this->chan; + while ($chan && ! $chan->isClosing() && ($args = $chan->pop()) !== false) { + $callable = function () use ($args) { + try { + parent::sendRequest(...$args); + } catch (Throwable $e) { + // TODO: 视需要记录日志/打点 + } + }; + if ($this->concurrent) { + $this->concurrent->create($callable); + } else { + Coroutine::create($callable); + } + $callable = null; + $args = null; + } + } catch (Throwable $e) { + // TODO: 视需要记录日志/打点 + } finally { + $this->close(); + }
82-87: 子协程内未捕获的异常会污染日志并中断并发槽位
parent::sendRequest(...$args)可能抛出异常；当前仅在“调度”处 try/catch，子协程内异常未被捕获。请在可执行体内捕获。- $callable = fn () => parent::sendRequest(...$args); + $callable = function () use ($args) { + try { + parent::sendRequest(...$args); + } catch (Throwable $e) { + // TODO: 记录错误或打点，不要向上抛 + } + };
113-121: 优雅收敛：close 仅关闭 Channel，未等待已派发任务完成，可能丢尾部请求建议用 WaitGroup 或等效手段在关闭前短暂等待在途任务完成（带超时，防止卡退出）。
protected function close(): void { $chan = $this->chan; - $chan?->close(); + // 等待在途任务短暂收敛（示例 100ms，可调/可配置） + $this->wg?->wait(0.1); + $chan?->close(); if ($this->chan === $chan) { $this->chan = null; } }为支持上述等待，请在类中补充以下改动（文件其它位置，非选区增量）：
use Hyperf\Coroutine\WaitGroup; protected ?WaitGroup $wg = null; public function __construct(string $sdkIdentifier, string $sdkVersion, protected int $channelSize = 65535, int $concurrentLimit = 100,) { parent::__construct($sdkIdentifier, $sdkVersion); $this->wg = new WaitGroup(); if ($concurrentLimit > 0) { $this->concurrent = new Concurrent($concurrentLimit); } }在派发任务时配合 add/done：
$this->wg?->add(1); $callable = function () use ($args) { try { parent::sendRequest(...$args); } catch (Throwable $e) { /* log */ } finally { $this->wg?->done(); } };
61-68: 与 sendRequest 的交互导致“早退 + 丢单”
loop()在workerExited === true时直接返回且不创建通道；随后sendRequest()仍执行$chan?->push(...)并返回 202。请结合前述修改，在sendRequest()中检测workerExited/chan状态并同步回退。

37-45: 通道容量缺省值偏大，需评估内存与背压策略

$this->chan，在close()将其置空后可能触发“Call to a member function pop() on null”；虽被最外层 try/catch 吞掉，但会产生不必要的异常开销。- 双 while 与

49-59: 避免静默丢包与阻塞：对 Channel::push 使用短超时并在失败时回退为同步发送验证：Hyperf/Swoole 的 Channel::push 支持超时参数（float，默认 -1 阻塞），在超时或通道已关闭时返回 false；基于此，建议改为非阻塞 push 并在失败/通道不可用时回退到同步发送。文件：src/sentry/src/HttpClient/HttpClient.php 行 49-59。建议 patch：
public function sendRequest(Request $request, Options $options): Response { // Start the loop if not started yet $this->loop(); - // Push the request to the channel - $chan = $this->chan; - $chan?->push([$request, $options]); + // Worker 已退出或队列不可用：同步发送，避免静默丢包 + $chan = $this->chan; + if ($this->workerExited || ! $chan) { + return parent::sendRequest($request, $options); + } + // 非阻塞推送；失败（超时/已关闭）则回退为同步发送 + if ($chan->push([$request, $options], 0.001) === false) { + return parent::sendRequest($request, $options); + } return new Response(202, ['X-Sentry-Request-Status' => ['Queued']], ''); }
