Eric Anderson 0754dac14d codec-http2: Correct last-stream-id for HEADERS-triggered connection error (#10775)
Motivation:

When parsing HEADERS, connection errors can occur (e.g., too large of
headers, such that we don't want to HPACK decode them). These trigger a
GOAWAY with a last-stream-id telling the client which streams haven't
been processed.

Unfortunately that last-stream-id didn't include the stream for the
HEADERS that triggered the error. Since clients are free to silently
retry streams not included in last-stream-id, the client is free to
retransmit the request on a new connection, which will fail the
connection with the wrong last-stream-id, and the client is still free
to retransmit the request.

Modifications:

Have fatal connection errors (those that hard-cut the connection)
include all streams in last-stream-id, which guarantees the HEADERS'
stream is included and thus should not be silently retried by the HTTP/2
client.

This modification is heavy-handed, as it will cause racing streams to
also fail, but alternatives that provide precise last-stream-id tracking
are much more invasive. Hard-cutting the connection is already
heavy-handed and so is rare.

Result:

Fixes #10670

Netty Project

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients.

How to build

For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.

You require the following to build Netty:

Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.

Branches to look

Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.

Usage with JDK 9

Netty can be used in modular JDK9 applications as a collection of automatic modules. The module names follow the reverse-DNS style, and are derived from subproject names rather than root packages due to historical reasons. They are listed below:

  • io.netty.all
  • io.netty.buffer
  • io.netty.codec
  • io.netty.codec.dns
  • io.netty.codec.haproxy
  • io.netty.codec.http
  • io.netty.codec.http2
  • io.netty.codec.memcache
  • io.netty.codec.mqtt
  • io.netty.codec.redis
  • io.netty.codec.smtp
  • io.netty.codec.socks
  • io.netty.codec.stomp
  • io.netty.codec.xml
  • io.netty.common
  • io.netty.handler
  • io.netty.handler.proxy
  • io.netty.resolver
  • io.netty.resolver.dns
  • io.netty.transport
  • io.netty.transport.epoll (native omitted - reserved keyword in Java)
  • io.netty.transport.kqueue (native omitted - reserved keyword in Java)
  • io.netty.transport.unix.common (native omitted - reserved keyword in Java)
  • io.netty.transport.rxtx
  • io.netty.transport.sctp
  • io.netty.transport.udt

Automatic modules do not provide any means to declare dependencies, so you need to list each used module separately in your module-info file.
