Netty 4.1.31.Final 发布,经典开源 Java 网络服务框架

Netty 4.1.31.Final 发布了,该版本包含错误修复,以及一些重要的改进和性能提升。除此之外,还提供了对 TLSv1.3 的支持(通过 Java 11 或 netty-tcnative / netty-tcnative-boringssl-static 实现)。

重要的变更内容:

  • Fix leak and corruption bugs in CompositeByteBuf (#8438)
  • Optimize AbstractByteBuf.getCharSequence() in US_ASCII case (#8392)
  • (fix) incorrect reachability assumption in ResourceLeakDetector (#8410)
  • Correctly detect if KeyManagerFactory is supported by OpenSSL even when sun.security.x509.* can not be accessed and bouncycastle is not on the classpath. (#8415)
  • Reduce overhead by ByteBufUtil.decodeString(…) which is used by AbstractByteBuf.toString(...) and AbstractByteBuf.getCharSequence(...) (#8388)
  • CompositeByteBuf.decompose(…) does not correctly slice content (#8403)
  • Allow to use TLSv1.3 with netty-tcnative withe java versions prior to 11 (#8394)
  • Add support for TLSv1.3 #8293)
  • Add support for boringssl and TLSv1.3 (#8412)
  • Ensure OpenSslEngine will not try to call SSL_free multiple times even when constructor throws #8399)
  • Add full JdkSslContext public constructor #8389)
  • Prevent NPE when attempting to set client key material with no alias #8378)
  • epoll_wait produces an EINVAL error since 4.1.30 #8350)
  • Correctly parse /etc/resolv.conf when contain multiple entries for searchdomain #8351)
  • Correctly decrement pending bytes when submitting AbstractWriteTask fails #8349)
  • Fix SelectableChannel support in NioEventLoop #8344)
  • Added option to do busy-wait on epoll #8267)
  • Ensure X509KeyManager methods are called on the correct time when using server-side and support more methods of ExtendedSSLSession #8283)
  • Do the same extended checks as the JDK when a X509TrustManager is used with the OpenSSL provider #8307)

支持 TLSv1.3

在这个版本中,开发团队以各种方式添加了对它的支持,当一下任何一个条件满足时:

  • 使用 Java11 或更高版本
  • 使用 netty-tcnative(针对 OpenSSL 1.1.1+ 构建)和 Java8 +
  • 使用 netty-tcnative-boringssl-static 和 Java8 +

即可启用 TLSv1.3。也就是说默认情况下没有启用 TLSv1.3 ,所以如果你想使用它,你需要在配置 SslContextBuilder 时显式启用它以使用 TLSv1.3。
