Robert Varga b87cb06b93 Do not call System.nanoTime() in ReadTimeoutHandler.channelRead()
Motivation:

We mitigate callouts to System.nanoTime() in SingleThreadEventExecutor
as it is 'relatively expensive'. On a modern system, tak translates to
about 20ns per call. With channelReadComplete() we can side-step this in
channelRead().

Modifications:

Introduce a boolean flag, which indicates that a read batch is currently
on-going, which acts as a flush guard for lastReadTime. Update
lastReadTime in channelReadComplete() just before setting the flag to
false. We set the flag to true in channelRead().

The periodic task examines the flag, and if it observes it to be true,
it will reschedule the task for the full duration. If it observes as
false, it will read lastReadTime and adjust the delay accordingly.

Result:

ReadTimeoutHandler calls System.nanoTime() only once per read batch.

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

The 'master' branch is where the development of the latest major version lives on. The development of all other 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.
