0c817d61b3 Upgrading to HTTP/2 draft 14 framing
Motivation:

HTTP/2 draft 14 came out a couple of weeks ago and we need to keep up
with the spec.

Modifications:

- Removed use of segment throughout.
- Added new setting for MAX_FRAME_SIZE. Used by the frame reader/writer
rather than a constant.
- Added new setting for MAX_HEADER_LIST_SIZE. This is currently unused.
- Expanded the header size to 9 bytes. The frame length field is now 3
bytes and added logic for checking that it falls within the valid range.

Result:

Netty will support HTTP/2 draft 14 framing. There will still be some
work to do to be compliant with the HTTP adaptation layer.

26116541ed Fix example for Http Upload
Motivation:
The example mis handle two elements:
1) Last message is a LastHttpContent and is not taken into account by
the server handler
2) The client makes a sync on last write (chunked) but there is no flush
before, therefore the sync is waiting forever.

Modifications:
1) Take into account the message LastHttpContent in simple Get.
2) Removes sync but add flush for each post and multipost parts

Results:
Example is no more blocked after get test.

Should be done also in 4.0 and Master (similar changes)

a242224646 Add socksx package which supports SOCKS 4/4a/5
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

b41b11c53d Introduced HTTP/2 frame to HTTP/1.x translation layer.
Motivation:

The HTTP/2 codec currently provides direct callbacks to access stream events/data. The HTTP/2 codec provides the protocol support for HTTP/2 but it does not pass messages up the context pipeline. It would be nice to have a decoder which could collect the data framed by HTTP/2 and translate this into traditional HTTP type objects. This would allow the traditional Netty context pipeline to be used to separate processing concerns (i.e. HttpContentDecompressor).  It would also be good to have a layer which can translate FullHttp[Request|Response] objects into HTTP/2 frame outbound events.

Modifications:

Introduce a new InboundHttp2ToHttpAdapter and supporting classes which will translate HTTP/2 stream events/data into HttpObject objects. Introduce a new DelegatingHttp2HttpConnectionHandler which will translate FullHttp[Request|Response] objects to HTTP/2 frame events.

Result:

Introduced HTTP/2 frame events to HttpObject layer.
Introduced FullHttp[Request|Response] to HTTP/2 frame events.
Introduced new unit tests to support new code.
Updated HTTP/2 client example to use new code.
Miscelaneous updates and bug fixes made to support new code.

f8bee2e94c Make Nio/EpollEventLoop run on a ForkJoinPool
Related issue: #2250

Motivation:

Prior to this commit, Netty's non blocking EventLoops
were each assigned a fixed thread by which all of the
EventLoop's I/O and handler logic would be performed.

While this is a fine approach for most users of Netty,
some advanced users require more flexibility in
scheduling the EventLoops.

Modifications:

Remove all direct usages of threads in MultithreadEventExecutorGroup,
SingleThreadEventExecutor et al., and introduce an Executor
abstraction instead.

The way to think about this change is, that each
iteration of an eventloop is now a task that gets scheduled
in a ForkJoinPool.

While the ForkJoinPool is the default, one also has the
ability to plug in his/her own Executor (aka thread pool)
into a EventLoop(Group).

Result:

Netty hands off thread management to a ForkJoinPool by default.
Users can also provide their own thread pool implementation and
get some control over scheduling Netty's EventLoops

46a6312cba Remove compressed flag from HTTP/2
Motivation:

There are still a few places in the HTTP/2 code that have the compressed
flag (from pre-draft 13). Need to remove this flag since it's no longer
used.

Modifications:

Various changes to remove the flag from the writing path.

Result:

No references to the compressed flag.

282d6e73b8 Add WebSocket Extension handlers for client and server.
Add permessage-deflate and deflate-frame WebSocket extension
implementations.

Motivation:

Need to compress HTTP WebSocket frames payload.

Modifications:

- Move UTF8 checking of WebSocketFrames from frame decoder to and
external handler.
- Change ZlibCodecFactory in order to use ZLib implentation instead of
JDK if windowSize or memLevel is different from the default one.
- Add WebSocketServerExtensionHandler and
WebSocketClientExtensionHandler to handle WebSocket Extension headers.
- Add DeflateFrame and PermessageDeflate extension implementations.

cbe20faf6c Adding payload to the Http2Client example.
Modifications:
When trying out the Http2Client example I noticed that adding a request
payload would not cause a data frame to written. This seems to be
because writeHeaders completes the promise, and then the writeData
call ends up in FlowControlWriter.writeFrame, isDone is true and
the data released and the call aborted and returned.
Adding a new promise for the writeData method allows a data frame to be
written.

Result:
A body/payload can now be sent to the server. The example was updated to
simply echo the payload received back to the calling client.

Motivation:
When running the Http2Client the data returned from the server, the
"Hello World" string, is supposed to be printed but instead the following
is displayed:
Received message:

Modifications:
Use the aggregated buffer to print out.

Result:
The example now logs the correct data sent from the server:

de2872f7f7 Introduce TextHeaders and AsciiString
Motivation:

We have quite a bit of code duplication between HTTP/1, HTTP/2, SPDY,
and STOMP codec, because they all have a notion of 'headers', which is a
multimap of string names and values.

Modifications:

- Add TextHeaders and its default implementation
- Add AsciiString to replace HttpHeaderEntity
  - Borrowed some portion from Apache Harmony's java.lang.String.
- Reimplement HttpHeaders, SpdyHeaders, and StompHeaders using
  TextHeaders
- Add AsciiHeadersEncoder to reuse the encoding a TextHeaders
  - Used a dedicated encoder for HTTP headers for better performance
    though
- Remove shortcut methods in SpdyHeaders
- Remove shortcut methods in SpdyHttpHeaders
- Replace SpdyHeaders.getStatus() with HttpResponseStatus.parseLine()

Result:

- Removed quite a bit of code duplication in the header implementations.
- Slightly better performance thanks to improved header validation and
  hash code calculation

1d8c7ff52e Addings helper methods to HTTP/2 handler
Motivation:

Subclasses of AbstractHttp2ConnectionHandler have to implement all frame
handler methods, many of which can be ignored in many cases.  Also there
is no easy way to access the connection object.

Modifications:

Added default implementations for frame handler methods to
AbstractHttp2ConnectionHandler, and added an accessor for the
connection.

Also fixed example test for HTTP/2 with cleartext upgrade. It must have
been broken by recent commits.

Result:

AbstractHttp2ConnectionHandler is more subclass-friendly.

bcb180b08d Reducing memory usage for HTTP/2
Motivation:

The connection, priority tree, and inbound/outbound flow controllers
each maintain a separate map for stream information. This is wasteful
and complicates the design since as streams are added/removed, multiple
structures have to be updated.

Modifications:

- Merging the priority tree into Http2Connection. Then we can use
Http2Connection as the central stream repository.

- Adding observer pattern to Http2Connection so flow controllers can be
told when a new stream is created, closed, etc.

- Adding properties for inboundFlow/outboundFlow state to Http2Stream.
This allows the controller to access flow control state directly from
the stream without requiring additional structures.

- Separate out the StreamRemovalPolicy and created a "default"
implementation that runs periodic garbage collection.  This used to be
internal to the outbound flow controller, but I think it is more general
than that.

Result:

HTTP/2 classes will require less storage for new streams.

2e98566916 Introduce MessageAggregator and DecoderResultProvider
Motivation:

We have different message aggregator implementations for different
protocols, but they are very similar with each other.  They all stems
from HttpObjectAggregator.  If we provide an abstract class that provide
generic message aggregation functionality, we will remove their code
duplication.

Modifications:

- Add MessageAggregator which provides generic message aggregation
- Reimplement all existing aggregators using MessageAggregator
- Add DecoderResultProvider interface and extend it wherever possible so
  that MessageAggregator respects the state of the decoded message

Result:

Less code duplication

7667a4a32e Use a forked exec-maven-plugin instead of maven-antrun-plugin
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.

3f8194557b Clean up the examples
Motivation:

The examples have not been updated since long time ago, showing various
issues fixed in this commit.

Modifications:

- Overall simplification to reduce LoC
  - Use system properties to get options instead of parsing args.
  - Minimize option validation
  - Just use System.out/err instead of Logger
  - Do not pass config as parameters - just access it directly
  - Move the main logic to main(String[]) instead of creating a new
    instance meaninglessly
    - Update netty-build-21 to make checkstyle not complain
  - Remove 'throws Exception' clause if possible
- Line wrap at 120 (previously at 80)
- Add an option to enable SSL for most examples
- Use ChannelFuture.sync() instead of await()
- Use System.out for the actual result. Use System.err otherwise.
- Delete examples that are not very useful:
  - applet
  - websocket/html5
  - websocketx/sslserver
  - localecho/multithreaded
- Add run-example.sh which simplifies launching an example from command
  line
- Rewrite FileServer example

Result:

Shorter and simpler examples.  A user can focus more on what it actually
does than miscellaneous stuff.  A user can launch an example very
easily.

cb66866730 Future compatibility with TLS ALPN
Motivation:

According to TLS ALPN draft-05, a client sends the list of the supported
protocols and a server responds with the selected protocol, which is
different from NPN.  Therefore, ApplicationProtocolSelector won't work
with ALPN

Modifications:

- Use Iterable<String> to list the supported protocols on the client
  side, rather than using ApplicationProtocolSelector
- Remove ApplicationProtocolSelector

e167ec51eb Add unified NextProtoNego extension support to SslContext
Motivation:

- OpenSslEngine and JDK SSLEngine (+ Jetty NPN) have different APIs to
  support NextProtoNego extension.
  - It is impossible to configure NPN with SslContext when the provider
    type is JDK.

Modification:

- Implement NextProtoNego extension by overriding the behavior of
  SSLSession.getProtocol() for both OpenSSLEngine and JDK SSLEngine.
  - SSLEngine.getProtocol() returns a string delimited by a colon (':')
    where the first component is the transport protosol (e.g. TLSv1.2)
    and the second component is the name of the application protocol
- Remove the direct reference of Jetty NPN classes from the examples
- Add SslContext.newApplicationProtocolSelector

Result:

- A user can now use both JDK SSLEngine and OpenSslEngine for NPN-based
  protocols such as HTTP2 and SPDY

72ccf83861 Clean up the execution mechanism of examples
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:

- example/pom.xml has quite a bit of duplication.

- 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

a72230061d Add an OpenSslEngine and the universal API for enabling SSL
Motivation:

Some users already use an SSLEngine implementation in finagle-native. It
wraps OpenSSL to get higher SSL performance.  However, to take advantage
of it, finagle-native must be compiled manually, and it means we cannot
pull it in as a dependency and thus we cannot test our SslHandler
against the OpenSSL-based SSLEngine.  For an instance, we had #2216.

Because the construction procedures of JDK SSLEngine and OpenSslEngine
are very different from each other, we also need to provide a universal
way to enable SSL in a Netty application.

Modifications:

- Pull netty-tcnative in as an optional dependency.
  http://netty.io/wiki/forked-tomcat-native.html
- Backport NativeLibraryLoader from 4.0
- Move OpenSSL-based SSLEngine implementation into our code base.
  - Copied from finagle-native; originally written by @jpinner et al.
  - Overall cleanup by @trustin.
- Run all SslHandler tests with both default SSLEngine and OpenSslEngine
- Add a unified API for creating an SSL context
  - SslContext allows you to create a new SSLEngine or a new SslHandler
    with your PKCS#8 key and X.509 certificate chain.
  - Add JdkSslContext and its subclasses
  - Add OpenSslServerContext
- Add ApplicationProtocolSelector to ensure the future support for NPN
  (NextProtoNego) and ALPN (Application Layer Protocol Negotiation) on
  the client-side.
- Add SimpleTrustManagerFactory to help a user write a
  TrustManagerFactory easily, which should be useful for those who need
  to write an alternative verification mechanism. For example, we can
  use it to implement an unsafe TrustManagerFactory that accepts
  self-signed certificates for testing purposes.
- Add InsecureTrustManagerFactory and FingerprintTrustManager for quick
  and dirty testing
- Add SelfSignedCertificate class which generates a self-signed X.509
  certificate very easily.
- Update all our examples to use SslContext.newClient/ServerContext()
- SslHandler now logs the chosen cipher suite when handshake is
  finished.

Result:

- Cleaner unified API for configuring an SSL client and an SSL server
  regardless of its internal implementation.
- When native libraries are available, OpenSSL-based SSLEngine
  implementation is selected automatically to take advantage of its
  performance benefit.
- Examples take advantage of this modification and thus are cleaner.

35ab47a5d5 Merging HTTP/2 preface logic into connection handler
Motivation:

The HTTP/2 connection preface logic is currently handled in two places.
Reading/writing the client preface string is handled by
Http2PrefaceHandler while the reading/writing of the initial settings
frame is handled by AbstractHttp2ConnectionHandler. Given that their
isn't much code in Http2PrefaceHandler, it makes sense to just merge it
into the preface handling logic of AbstractHttp2ConnectionHandler. This
will also make configuring the pipeline simpler for HTTP/2.

Modifications:

Removed Http2PrefaceHandler and added it's logic to
AbstractHttp2ConnectionHandler. Updated other classes depending on
Http2PrefaceHandler.

Result:

All of the HTTP/2 connection preface processing logic is now in one
place.

e22aed284b Various fixes for compliance with HTTP/2 spec
Motivation:

A few items were identified where the http2 codec is out of compliance
with the spec.

Modifications:

- Fixed handling of priority weight on the wire. Now adding 1 after
reading from the wire and subtracing 1 before writing.

- Fixed handling of next stream ID. Client streamIds were starting at 3,
but they need to start at 1 to allow the upgrade from HTTP/1.1. Also
making next stream ID logic more flexible. Allowing the next created
stream to be any number in the sequence following the previously created
stream.

- Disallowing SETTINGS frames with ENABLE_PUSH specified for server
endpoints. This means that attempts to write this frame from a server,
or read it from a client will fail.

Result:

The http2 implementation will be more inline with the spec.

d5148bfee9 Adding context to Http2FrameObserver
Motivation:

The Http2FrameObserver isn't provided the ChannelHandlerContext when
it's called back. This will force observers to find an alternative means
of obtaining the context if they need to do things like copying buffers.

Modifications:

Changed the Http2FrameReader and Http2FrameObserver to include the
context. Updated all other uses of these interfaces.

ca7c53d45f Add support for HTTP/2 draft 12.
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.

ee3f3661f0 HTTP2 server should not send preface string
Motivation:

See: https://github.com/netty/netty/issues/2402
See: https://tools.ietf.org/html/draft-ietf-httpbis-http2-10#section-3.5

Only the client should send the preface string, the server should not.

"The server connection header consists of just a SETTINGS frame (Section 6.5)
 that MUST be the first frame the server sends in the HTTP/2 connection."

Modifications:

Split out Http2ClientPrefaceWriter and Http2ServerPrefaceReader from
Http2FrameEncoder and Http2FrameDecoder.  The new channel handlers are added
to the pipeline and remove themselves after the preface is written/read.

Result:

HTTP2 client sends preface, server does not, in compliance with spec.

Copy the SDPY example to add SSL and NPN negotiation to the HTTP2 example.

Result:

Http2Server and Http2Client examples use SSL.

9496c1a4ed HTTP2 example server should also log.
Motivation:

The HTTP2 example client logs, and it's useful to show what's
going on.  It'd be sweet if the server did too.

Modifications:

Added Http2FrameLogger to example server pipeline.

Result:

HTTP2 example server will log frames.

350c8ef42a SPDY: refactor frame codec implementation
Motivation:

Currently, the SPDY frame encoding and decoding code is based upon
the ChannelHandler abstraction. This requires maintaining multiple
versions for 3.x and 4.x (and possibly 5.x moving forward).

Modifications:

The SPDY frame encoding and decoding code is separated from the
ChannelHandler and SpdyFrame abstractions. Also test coverage is
improved.

Result:

SpdyFrameCodec now implements the ChannelHandler abstraction and is
responsible for creating and handling SpdyFrame objects.

8615f7a69e Add a Example for Memcache Binary Codec
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.

31a36e09ad [#2353] Use a privileged block to get ClassLoader and System property if needed
Motivation:
When using System.getProperty(...) and various methods to get a ClassLoader it will fail when a SecurityManager is in place.

Modifications:
Use a priveled block if needed. This work is based in the PR #2353 done by @anilsaldhana .

Result:
Code works also when SecurityManager is present

69826637a8 Adding examples for HTTP/2 framing.
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.

7c6f862d98 Adding origins whitelist support for CORS
Motivation:
Currently the CORS support only handles a single origin, or a wildcard
origin. This task should enhance Netty's CORS support to allow multiple
origins to be specified. Just being allowed to specify one origin is
particulary limiting when a site support both http and https for
example.

Modifications:
- Updated CorsConfig and its Builder to accept multiple origins.

Result:
Users are now able to configure multiple origins for CORS.

20d2fb8c2e SPDY client example
Demonstrates the usage of SPDY from a client perspective. One can also
use a SPDY-enabled browser as a client, but it’s easier to understand
the internals of the protocol from a client point-of-view if you have
some code you can debug.

- Instead of using 'bundle' packaging, use 'jar' packaging.  This is

  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.
