Jeremy Kuhn 009497f5f9 Fix support for optional encoders errors in HttpContentCompressor (#11582)
Motivation:

- Fix `HttpContentCompressor` errors due to missing optional compressor libraries such as Brotli and Zstd at runtime.
- Improve support for optional encoders by only considering the `CompressionOptions` provided to the constructor and ignoring those for which the encoder is unavailable.

Modification:

The `HttpContentCompressor` constructor now only creates encoder factories for the CompressionOptions passed to the constructor when the encoder is available which must be checked for Brotli and Zstd. In case of Brotli, it is not possible to create BrotliOptions if brotly4j is not available so there's actually nothing to check. In case of Zstd, I had to create class `io.netty.handler.codec.compression.Zstd` similar to `io.netty.handler.codec.compression.Brotli` which is used to check that zstd-jni is availabie at runtime.

The `determineEncoding()` method had to change as well in order to ignore encodings for which there's no `CompressionEncoderFactory` instance.

When the HttpContentCompressor is created using deprecated constructor (ie. with no CompressionOptions), we consider all available encoders.

Result:

Fixes #11581.

Build project

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+ / 4.1+) 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 4.1 resides in the branch '3.9' and the branch '4.1' 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.
