Release Notes

# Release Notes ## 🐛 Bug Fixes ### HTTP/2 Server - **Fixed Safari Compatibility Issue**: Resolved a flow control compatibility issue when the HTTP/2 server sends large files to Safari browsers. - **Fixed Data Race in Cached `Date` Response Header**: Fixed a data race condition in the cached `Date` response header for the HTTP/2 server in multi-threaded mode. - **Fixed `package_max_length` Configuration Not Taking Effect**: - The server now returns a `413 Payload Too Large` error if the `Content-Length` in the received `HEADERS` frame exceeds the configured value. - The server sends an `HTTP/2 RST_STREAM` frame to terminate the stream if the total length of consecutively received `DATA` frames exceeds the configured value. - **Fixed Memory Out-of-Bounds in Multi-threaded Coroutine Mode**: Resolved a memory out-of-bounds issue when enabling `enable_reuse_port` in the multi-threaded coroutine version of the HTTP/2 server. - **Fixed TLS Variable Destruction Issue**: Fixed a `double free` issue occurring during the destruction of TLS (Thread Local Storage) variables upon thread exit in the multi-threaded HTTP/2 server. ### Redis Server - Fixed packet assembly anomalies in `Redis\Server::format()` when processing large strings. ### WebSocket Server - **Fixed Control Frame Data Contamination**: Resolved an issue where automatically replied `ping`/`pong`/`close` control frames from the WebSocket server carried residual data from previous text or binary frames due to uncleared buffers. ### Multi-threading Related - **Fixed Data Race in `swoole_get_task_tmpdir()`**: Resolved a data race condition when calling this function in a multi-threaded environment. - **Fixed Memory Out-of-Bounds Access in Runtime Hooks**: Fixed memory out-of-bounds access triggered when setting runtime hooks in a multi-threaded environment. - ⚠️ **Important Change**: Runtime hooks can now only be set in the main thread and must be configured before creating any child threads. ### Platform Compatibility - **Fixed FreeBSD Compilation Failure**: Resolved compilation failures on FreeBSD systems. ## ✨ Enhancements - **Added Android Platform Support**: Improved compatibility with the Android platform; now supported in Termux environments. - **Synchronized Updates from PHP 8.x curl Module**: Adapted relevant updates from the `curl` extension in PHP versions 8.1, 8.2, and 8.3. --- **Note**: This update includes several critical fixes for multi-threaded mode. Users utilizing multi-threaded mode are strongly advised to upgrade as soon as possible. # 更新记录 ## 🐛 Bug 修复 ### HTTP/2 服务器 - **修复 Safari 浏览器兼容性问题**：解决 HTTP/2 服务器在向 Safari 浏览器发送大文件时的流量控制兼容性问题 - **修复 Date 响应头缓存的数据竞争**：解决多线程模式下 HTTP/2 服务器的 `Date` 响应头缓存存在的数据竞争问题 - **修复 `package_max_length` 配置未生效**： - 当接收的 `Header` 帧中 `Content-Length` 超过配置值时，服务器将返回 `413 Payload Too Large` 错误 - 当连续接收的 `Data` 帧总长度超过配置值时,服务器将发送 `HTTP/2 RST_STREAM` 帧终止流 - **修复多线程协程模式下的内存越界**：解决多线程模式协程版 `HTTP/2` 服务器开启 `enable_reuse_port` 时发生的内存越界问题 - **修复 `TLS` 变量销毁问题**：解决多线程模式 `HTTP/2` 服务器在线程退出时 `TLS (Thread Local Storage)` 变量销毁时发生的 `double free` 问题 ### Redis 服务器 - 修复 `Redis\Server::format()` 处理大字符串出现的组包异常问题 ### WebSocket 服务器 - **修复控制帧数据污染问题**：解决 `WebSocket` 服务端自动回复的 `ping`/`pong`/`close` 控制帧因未清空缓存,导致携带前一个文本帧或二进制帧残留数据的问题 ### 多线程相关 - **修复 `swoole_get_task_tmpdir()` 数据竞争**：解决多线程环境下调用该函数时存在的数据竞争问题 - **修复运行时钩子的内存越界访问**：解决多线程环境下设置运行时钩子时触发的内存越界访问问题 - ⚠️ **重要变更**：运行时钩子现在仅允许在主线程中设置,且必须在创建任何子线程之前完成设置 ### 平台兼容性 - **修复 FreeBSD 编译失败**：解决在 FreeBSD 系统下的编译失败问题 ## ✨ 功能增强 - **新增 Android 平台支持**：提升在 Android 平台的兼容性,现已支持在 Termux 环境下运行 - **同步 PHP 8.x curl 模块更新**：适配 PHP 8.1、8.2 及 8.3 版本中 `curl` 扩展的相关更新 --- **注意事项**：本次更新包含多项多线程模式下的关键修复,建议使用多线程模式的用户尽快升级。
