v0.7.1

v0.7.1 (Apr 10, 2026)

🚀 Key Changes

✨ New Features

• Concurrency Primitives: Added sync.singleflight to deduplicate concurrent in-flight requests.
• High-Resolution Timing: New perf.hrtime for nanosecond-precision timing.
• Network Addressing: net.addr module extracted for centralized host:port parsing and handling.
• Compression Codecs: Added Snappy and LZ4 support in the compress module.

🔄 Changes

• Logger: Redesigned with a ring buffer and asynchronous flushing for reduced write latency.
• JSON: Encoding module rewritten in C for improved performance and RFC 8259 compliance.
• DNS Resolver: Reimplemented with a C-based wire format parser.
• Cluster Protocol: Packet header expanded to 4 bytes with enforced size limits — may affect protocol compatibility.
• Hive Workers: Now inherit package path and enforce restricted module access.
• Profiler: Renamed from profiler to perf.
• Timer: Refactored to use a unified command buffer; shutdown sequence now uses explicit OP_EXIT termination; refine locking in flipbuf and timer pool.

🛠️ Fixes

• TLS: Propagate handshake/write errors to callers; fix use-after-free in server ALPN handling.
• Signal: Fix async-signal-unsafe handler and cross-thread lua_sethook race condition.
• HTTP/2: Validate :status in responses; skip content-length check for no-body responses; mask WINDOW_UPDATE reserved bit; remove duplicate SETTINGS ACK during handshake.
• Worker: Fix lua_close ordering to prevent use-after-free.

🚀 关键改动

✨ 新特性

• 并发原语： 新增 sync.singleflight，用于合并相同的并发请求，避免重复执行。
• 高精度计时： 新增 perf.hrtime，提供纳秒级精度的时间测量能力。
• 网络地址模块： 抽取 net.addr 模块，统一处理 host:port 的解析与管理。
• 压缩编解码器： 在 compress 模块中新增 Snappy 和 LZ4 支持。

🔄 变更

• 日志系统： 重新设计，采用环形缓冲区与异步刷新机制，降低写入延迟。
• JSON 模块： 编码模块用 C 重写，性能更优，符合 RFC 8259 规范。
• DNS 解析器： 基于 C 实现的 wire format 解析器重写，性能与可靠性提升。
• 集群协议： 数据包头扩展至 4 字节，并强制校验包大小上限——可能影响协议兼容性。
• Hive 工作线程： 现在会继承 package path，并限制模块访问权限。
• Profiler： 模块从 profiler 重命名为 perf。
• 定时器： 重构为统一命令缓冲区；关闭流程改为通过显式 OP_EXIT 命令终止线程；优化 flipbuf 与 timer pool 中的加锁逻辑。

🛠️ 修复

• TLS： 将握手/写入错误正确传递给调用方；修复服务端 ALPN 处理中的 use-after-free 问题。
• Signal： 修复异步信号不安全的处理函数及跨线程 lua_sethook 竞态条件。
• HTTP/2： 校验响应中的 :status 字段；对无响应体的请求跳过 content-length 校验；屏蔽 WINDOW_UPDATE 保留位；移除握手阶段重复发送的 SETTINGS ACK。
• Worker： 修正 lua_close 调用顺序，防止 use-after-free。
