Motivation:
When running the examples using the provided run-examples.sh script the
log level is 'info' level. It can be handy to be able to configure a
different level, for example 'debug', while learning and trying out the
the examples.
Modifications:
Added a dependency to logback-classic to the examples pom.xml, and also
added a logback configuration file. The log level can be configured by
setting the 'logLevel' system property, and if that property is not set
the default will be 'info' level.
The run-examples.sh was updated to show an example of using the system
property to set the log level to 'debug'
Result:
It is now possible to turn on debug logging by settnig a system property
on the command line.
Related issue: #1133
Motivation:
There is no support for client socket connections via a proxy server in
Netty.
Modifications:
- Add a new module 'handler-proxy'
- Add ProxyHandler and its subclasses to support SOCKS 4a/5 and HTTP(S)
proxy connections
- Add a full parameterized test for most scenarios
- Clean up pom.xml
Result:
A user can make an outgoing connection via proxy servers with only
trivial effort.
Motivation:
SOCKS 4 and 5 are very different protocols although they share the same
name. It is not possible to incorporate the two protocol versions into
a single package.
Modifications:
- Add a new package called 'socksx' to supercede 'socks' package.
- Add SOCKS 4/4a support to the 'socksx' package
Result:
codec-socks now supports all SOCKS versions
Motivation:
maven-antrun-plugin does not redirect stdin, and thus it's impossible to
run interactive examples such as securechat-client and telnet-client.
org.codehaus.mojo:exec-maven-plugin redirects stdin, but it buffers
stdout and stderr, and thus an application output is not flushed timely.
Modifications:
Deploy a forked version of exec-maven-plugin which flushes output
buffers in a timely manner.
Result:
Interactive examples work. Launches faster than maven-antrun-plugin.
Motivation:
exec-maven-plugin does not flush stdout and stderr, making the console
output from the examples invisible to users
Modification:
Use maven-antrun-plugin instead
Result:
A user sees the output from the examples immediately.
Motivation:
- There's no way to pass an argument to an example.
- Assigning a Maven profile for each example is an overkill.
It makes the pom.xml crowded.
Modifications:
- Remove example profiles from example/pom.xml
- Keep the list of examples in run-example.sh
- run-example.sh passes all options to exec-maven-plugin.
For example, we can now do this:
./run-example.sh -Dssl -Dport=443 http-server
Result:
- It's much easier to add a new example and provide an easy way to
launch it.
- We can still pass an arbitrary argument to the example being launched.
(I'll update all examples to make them get their options from system
properties rather than from args[].
Motivation:
Build fails with JDK 8 because npn-boot does not work with JDK 8
Modifications:
Do not specify bootclasspath when on JDK 8
Result:
Build is green again.
Motivation:
- example/pom.xml has quite a bit of duplication.
- We expect that we depend on npn-boot in more than one module in the
near future. (e.g. handler, codec-http, and codec-http2)
Modification:
- Deduplicate the profiles in example/pom.xml
- Move the build configuration related with npn-boot to the parent pom.
- Add run-example.sh that helps a user launch an example easily
Result:
- Cleaner build files
- Easier to add a new example
- Easier to launch an example
- Easier to run the tests that relies on npn-boot in the future
Motivation:
It's useful to have netty-tcnative dependency in netty-example because
we can play with OpenSslEngine from our IDE.
Modifications:
Add netty-tcnative to example/pom.xml
Motivation:
Draft 12 has just arrived and has quite a few changes. Need to update in
order to keep current with the spec.
Modifications:
This is a rewrite of the original (draft 10) code. There are only 2
handlers now: preface and connection. The connection handler is now
callback based rather than frame based (there are no frame classes
anymore). AbstractHttp2ConnectionHandler is the base class for any
HTTP/2 handlers. All of the stream priority logic now resides in the
outbound flow controller, and its interface exposes methods for
adding/updating priority for streams.
Upgraded to hpack 0.7.0, which is used by draft12. Also removed
draft10 code and moved draft12 code to the ../http2 package
(no draft subpackage).
Result:
Addition of a HTTP/2 draft 12 support.
Motivation:
Currently, there exists no example which shows how to use the memcache binary
protocol.
Modifications:
Add an example client and client handler to show how to utilize the binary
protocol in a memcache client with a simple interactive shell.
Result:
Users looking for an example can now start off with the provided one.
Motivation:
Provide some example code to show how to bootstrap client and server for
use with HTTP/2 framing.
Modifications:
- Fixed Http2ConnectionHandler to allow headers after stream creation.
Needed for response headers.
- Added toString() to all frame classes to help with debugging/logging
- Added example classes for HTTP/2
Result:
HTTP/2 connections now properly support response headers. Examples for
HTTP/2 provided with the distribution of examples module.
After your change, what will change.
- Move the version number to the parent pom's pluginManagement section
- Remove unnecessary system properties
- Increase the scope of execution from compile to runtime
- Fixes#2003 properly
- Instead of using 'bundle' packaging, use 'jar' packaging. This is
more robust because some strict build tools fail to retrieve the
artifacts from a Maven repository unless their packaging is not 'jar'.
- All artifacts now contain META-INF/io.netty.version.properties, which
provides the detailed information about the build and repository.
- Removed OSGi testsuite temporarily because it gives false errors
during split package test and examination.
- Add io.netty.util.Version for easy retrieval of version information
