ed9d6c79bc [#4972] Remove misleading argument from HttpServerUpgradeHandler.UpgradeCodec.upgradeTo
Motivation:

upgradeTo(...) takes the response as paramater, but the respone itself was already written to the Channel. This gives the user the impression the response can be changed or even act on it which may not be safe anymore once it was written and has been released.

Modifications:

Remove the response param from the method.

Result:

Less confusion and safer usage.

3d7cec6376 Bug fix for HttpPostMultipartRequestDecoder part decoding with an invalid charset not reported as an ErrorDataDecoderException
Motivation:

The current HttpPostMultipartRequestDecoder can decode multipart/form-data parts with a Content-Type that specifies a charset. When this charset is invalid the Charset.forName() throws an unchecked UnsupportedCharsetException. This exception is not catched by the decoder. It should actually be rethrown as an ErrorDataDecoderException, because the developer using the API would expect this validation failure to be reported as such.

Modifications:

Add a catch block for UnsupportedCharsetException and rethrow it as an ErrorDataDecoderException.

Result:

UnsupportedCharsetException are now rethrown as ErrorDataDecoderException.

68bbd4e966 Handle only those http requests that equal to adjusted websocket path
Motivation:

It will be easier to support websockets in server application by using WebSocketServerProtocolHandshakeHandler class and not reinvent its functionality. But currently it handles all http requests as if they were websocket handshake requests.

Modifications:

Check if http request path is equals to adjusted websocket path.
Fixed example of websocket server implementation.

Result:

WebSocketServerProtocolHandshakeHandler handles only websocket handshake requests.

9aac6dac2e [#4386] ByteToMessage.decodeLast(...) should not call decode(...) if buffer is empty.
Motivation:

If the input buffer is empty we should not have decodeLast(...) call decode(...) as the user may not expect this.

Modifications:

- Not call decode(...) in decodeLast(...) if the input buffer is empty.
- Add testcases.

Result:

decodeLast(...) will not call decode(...) if input buffer is empty.

41d0a81691 Use ByteBufAllocator to allocate ByteBuf for FullHttpMessage Motivation: When converting SPDY or HTTP/2 frames to HTTP/1.x, netty always used an unpooled heap ByteBuf.
Modifications:
When constructing the FullHttpMessage pass in the ByteBuf to use via the ByteBufAllocator assigned via the context.

Result:
The ByteBuf assigned to the FullHttpMessage can now be configured as a pooled/unpooled, direct/heap based ByteBuf via the ByteBufAllocator used.

333f55e9ce Add unescapeCsvFields to parse a CSV line and implement CombinedHttpHeaders.getAll
Motivation:

See #4855

Modifications:

Unfortunately, unescapeCsv cannot be used here because the input could be a CSV line like `"a,b",c`. Hence this patch adds unescapeCsvFields to parse a CSV line and split it into multiple fields and unescaped them. The unit tests should define the behavior of unescapeCsvFields.

Then this patch just uses unescapeCsvFields to implement `CombinedHttpHeaders.getAll`.

Result:

`CombinedHttpHeaders.getAll` will return the unescaped values of a header.

b112673554 ByteToMessageDecoder ChannelInputShutdownEvent support
Motivation:
b714297a44 introduced ChannelInputShutdownEvent support for HttpObjectDecoder. However this should have been added to the super class ByteToMessageDecoder, and ByteToMessageDecoder should not propegate a channelInactive event through the pipeline in this case.

Modifications:
- Move the ChannelInputShutdownEvent handling from HttpObjectDecoder to ByteToMessageDecoder
- ByteToMessageDecoder doesn't call ctx.fireChannelInactive() on ChannelInputShutdownEvent

Result:
Half closed events are treated more generically, and don't get translated into a channelInactive pipeline event.

a15ff32608 HttpObjectDecoder configurable initial buffer size
Motivation:
The initial buffer size used to decode HTTP objects is currently fixed at 128. This may be too small for some use cases and create a high amount of overhead associated with resizing/copying. The user should be able to configure the initial size as they please.

Modifications:
- Make HttpObjectDecoder's AppendableCharSequence initial size configurable

Result:
Users can more finely tune initial buffer size for increased performance or to save memory.

7ef6db3ffd [#4754] Correctly detect websocket upgrade
Motivation:

If the Connection header contains multiple values (which is valid) we fail to detect a websocket upgrade

Modification:

- Add new method which allows to check if a header field contains a specific value (and also respect multiple header values)
- Use this method to detect handshake

Result:

Correct detect handshake if Connection header contains multiple values (seperated by ',').

a0758e7e60 [#4794] Support window size flag by default if ZlibCodecFactory supports it.
Motivation:

If the ZlibCodecFactory can support using a custom window size we should support it by default in the websocket extensions as well.

Modifications:

Detect if a custom window size can be handled by the ZlibCodecFactory and if so enable it by default for PerMessageDeflate*ExtensionHandshaker.

Result:

Support window size flag by default in most installations.

7a562943ad [#4533] Ensure replacement of decoder is delayed after finishHandshake() is called
Motivation:

If the user calls handshake.finishHandshake() we need to ensure that the user has the chance to setup the pipeline before any WebSocketFrames are read. Because of this we need
to delay the removal of the HttpRequestDecoder.

Modifications:

- Remove the HttpRequestDecoder via the EventLoop and so delay it which gives the user a chance to setup the pipeline after finishHandshake() completes
- Add unit test for this.

Result:

Less surpising and correct behaviour even if the http response and websocket frame are received in one read operation.

d97f17060f Support non chunked HTTP request bodies larger than Integer.MAX_VALUE.
Motivation:

Request bodies can easily be larger than Integer.MAX_VALUE in practice.
There's no reason, or intention, for Netty to impose this artificial constraint.

Worse, it currently does not fail if the body is larger than this value;
it just silently only reads the first Integer.MAX_VALUE bytes and discards the rest.

This restriction doesn't effect chunked transfers, with no Content-Length header.

Modifications:

Force the use of `long HttpUtil.getContentLength(HttpMessage, long)` instead of
`long HttpUtil.getContentLength(HttpMessage, long)`.

Result:

Netty will support HTTP request bodies of up to Long.MAX_VALUE length.

4d6ab1d30d Fix missing trailing data on HTTP client upgrade
Motivation:

When HttpClientUpgradeHandler upgrades from HTTP/1 to another protocol,
it performs a two-step opertion:

1. Remove the SourceCodec (HttpClientCodec)
2. Add the UpgradeCodec

When HttpClientCodec is removed from the pipeline, the decoder being
removed triggers channelRead() event with the data left in its
cumulation buffer. However, this is not received by the UpgradeCodec
becuase it's not added yet. e.g. HTTP/2 SETTINGS frame sent by the
server can be missed out.

To fix the problem, we need to reverse the steps:

1. Add the UpgradeCodec
2. Remove the SourceCodec

However, this does not work as expected either, because UpgradeCodec can
send a greeting message such as HTTP/2 Preface. Such a greeting message
will be handled by the SourceCodec and will trigger an 'unsupported
message type' exception.

To fix the problem really, we need to make the upgrade process 3-step:

1. Remove/disable the encoder of SourceCodec
2. Add the UpgradeCodec
3. Remove the SourceCodec

Modifications:

- Add SourceCodec.prepareUpgradeFrom() so that SourceCodec can remove or
  disable its encoder
- Implement HttpClientCodec.prepareUpgradeFrom() properly
- Miscellaneous:
  - Log the related channel as well When logging the failure to send a
    GOAWAY

Result:

Cleartext HTTP/1-to-HTTP/2 upgrade works again.

b7415a3307 Add a reusable ArrayList to InternalThreadLocalMap
Motivation:

See #3411. A reusable ArrayList in InternalThreadLocalMap can avoid allocations in the following pattern:

```
List<...> list = new ArrayList<...>();

add something to list but never use InternalThreadLocalMap

return list.toArray(new ...[list.size()]);

```

Modifications:

Add a reusable ArrayList to InternalThreadLocalMap and update codes to use it.

Result:

Reuse a thread local ArrayList to avoid allocations.

e969b6917c Let CombinedChannelDuplexHandler correctly handle exceptionCaught. Related to [#4528]
Motivation:

ChannelInboundHandler and ChannelOutboundHandler both can implement exceptionCaught(...) method and so we need to dispatch to both of them.

Modifications:

- Correctly first dispatch exceptionCaught to the ChannelInboundHandler but also make sure the next handler it will be dispatched to will be the ChannelOutboundHandler
- Add removeInboundHandler() and removeOutboundHandler() which allows to remove one of the combined handlers
- Let *Codec extends it and not ChannelHandlerAppender
- Remove ChannelHandlerAppender

Result:

Correctly handle events and also have same behavior as in 4.0

fd5316ed6f ChunkedInput.readChunk parameter of type ByteBufAllocator
Motivation:
ChunkedInput.readChunk currently takes a ChannelHandlerContext object as a parameters. All current implementations of this interface only use this object to get the ByteBufAllocator object. Thus taking a ChannelHandlerContext as a parameter is more restrictive for users of this API than necessary.

Modifications:
- Add a new method readChunk(ByteBufAllocator)
- Deprecate readChunk(ChannelHandlerContext) and updates all implementations to call readChunk(ByteBufAllocator)

Result:
API that only requires ByteBufAllocator to use ChunkedInput.

c1f3200c87 Fix the incorrect usage/value of 'Connection: upgrade'
Motivation:

HttpClientUpgradeHandler uses HttpHeaderNames.UPGRADE as the value of
the 'Connection' header, which is incorrect. It should use
HttpHeaderValues.UPGRADE instead (note Names vs Values.)

Also, HttpHeaderValues.UPGRADE should be 'upgrade' rather than
'Upgrade', as defined in:

- https://tools.ietf.org/html/rfc7230#section-6.7

Modifications:

- Use HttpHeaderValues.UPGRADE for a 'Connection' header
- Lowercase the value of HttpHeaderValues.UPGRADE

Result:

- Fixes #4508
- Correct behavior

9dd68d0c3e Fix IllegalReferenceCountException caused by HttpClientCodec.upgradeFrom()
Motivation:

On a successful protocol upgrade in HTTP, HttpClientUpgradeHandler calls
HttpClientCodec.upgradeFrom(), which removed both the HTTP encoder and
decoder from the pipeline immediately.

However, because the decoder is in the middle of the decode loop,
removing it from the pipeline immediately will cause the cumulation
buffer to be released prematurely.

This often leads to an IllegalReferenceCountException or missing first
response after the upgrade response.

Modifications:

- Remove the decoder *after* the decode loop is done

Result:

Fixes #4504

ef3a9b0acd Relax the sanity check in HttpClientUpgradeHandler
Motivation:

HttpClientUpgradeHandler currently throws an IllegalStateException when
the server sends a '101 Switching Protocols' response that has no
'Upgrade' header.

Some servers do not send the 'Upgrade' header on a successful protocol
upgrade and we could safely assume that the server accepted the
requested protocol upgrade in such a case, looking from the response
status code (101)

Modifications:

- Do not throw an IllegalStateException when the server responded 101
  without a 'Upgrade' header
- Note that we still check the equality of the 'Upgrade' header when it
  is present.

Result:

- Fixes #4523
- Better interoperability

4978266d52 Make cookie encoding conform better to RFC 6265 in STRICT mode.
Motivation:

- On the client, cookies should be sorted in decreasing order of path
  length. From RFC 6265:

      5.4.2. The user agent SHOULD sort the cookie-list in the following
      order:

        *  Cookies with longer paths are listed before cookies with
           shorter paths.

        *  Among cookies that have equal-length path fields, cookies with
           earlier creation-times are listed before cookies with later
           creation-times.

      NOTE: Not all user agents sort the cookie-list in this order, but
      this order reflects common practice when this document was
      written, and, historically, there have been servers that
      (erroneously) depended on this order.

  Note that the RFC does not define the path length of cookies without a
  path. We sort pathless cookies before cookies with the longest path,
  since pathless cookies inherit the request path (and setting a path
  that is longer than the request path is of limited use, since it cannot
  be read from the context in which it is written).

- On the server, if there are multiple cookies of the same name, only one
  of them should be encoded. RFC 6265 says:

      Servers SHOULD NOT include more than one Set-Cookie header field in
      the same response with the same cookie-name.

  Note that the RFC does not define which cookie should be set in the case
  of multiple cookies with the same name; we arbitrarily pick the last one.

Modifications:

- Changed the visibility of the 'strict' field to 'protected' in
  CookieEncoder.

- Modified ClientCookieEncoder to sort cookies in decreasing order of path
  length when in strict mode.

- Modified ServerCookieEncoder to return only the last cookie of a given
  name when in strict mode.

- Added a fast path for both strict mode in both client and server code
  for cases with only one cookie, in order avoid the overhead of sorting
  and memory allocation.

- Added unit tests for the new cases.

Result:

- Cookie generation on client and server is now more conformant to RFC 6265.

19658e9cd8 HTTP/2 Headers Type Updates
Motivation:
The HTTP/2 RFC (https://tools.ietf.org/html/rfc7540#section-8.1.2) indicates that header names consist of ASCII characters. We currently use ByteString to represent HTTP/2 header names. The HTTP/2 RFC (https://tools.ietf.org/html/rfc7540#section-10.3) also eludes to header values inheriting the same validity characteristics as HTTP/1.x. Using AsciiString for the value type of HTTP/2 headers would allow for re-use of predefined HTTP/1.x values, and make comparisons more intuitive. The Headers<T> interface could also be expanded to allow for easier use of header types which do not have the same Key and Value type.

Motivation:
- Change Headers<T> to Headers<K, V>
- Change Http2Headers<ByteString> to Http2Headers<CharSequence, CharSequence>
- Remove ByteString. Having AsciiString extend ByteString complicates equality comparisons when the hash code algorithm is no longer shared.

Result:
Http2Header types are more representative of the HTTP/2 RFC, and relationship between HTTP/2 header name/values more directly relates to HTTP/1.x header names/values.

e121c68e0f Created RTSPEncoder and RTSPDecoder which are now common for both requests and responses to be able to handle both types of messages on the same channel.
Keep RTSPRequestEncoder, RTSPRequestDecoder, RTSPResponseEncoder and
RTSPResponseDecoder for backwards compatibility but they now just extends
the generic encoder/decoder and are markes as deprecated.

Renamed the decoder test, because the decoder is now generic. Added
testcase for when ANNOUNCE request is received from server.

Created testcases for encoder.

Mark abstract base classes RTSPObjectEncoder and RTSPObjectDecoder as
deprecated, that functionality is now in RTSPEncoder and RTSPDecoder.

Added annotation in RtspHeaders to suppress warnings about deprecation, no need when
whole class is deprecated.

0555b0aefd HTTP Headers Over Deprecation
Motivation:
As part of recent efforts to rectify performance and make 4.1 headers more similar to 5.0 some methods were deprecated. Some of these methods were deprecated because they used String instead of CharSequence in the signature, which may require casting at the user level. Some of the deprecated methods have no direct alternatives and were done to inform a user the method will go away in future releases.

Modifications:
- Remove the deprecated qualifier from methods where no direct replacement exists

Result:
Less warnings in user code.

c7e3f6c6fd HTTP/2 defines using String instead of CharSequence
Motivation:
Http2CodecUtils has some static variables which are defined as Strings instead of CharSequence. One of these defines is used as a header name and should be AsciiString.

Modifications:
- Change the String defines in Http2CodecUtils to CharSequence

Result:
Types are more consistently using CharSequence and adding the upgrade header will require less work.

Motivation:
According to the SPDY spec https://www.chromium.org/spdy/spdy-protocol/spdy-protocol-draft3-1#TOC-3.2.1-Request header names must be lowercase. Our predefined SPDY extension headers are not lowercase.

Modifications
- SpdyHttpHeaders should define header names in lower case

Result:
Compliant with SPDY spec, and header validation code does not detect errors for our own header names.

59600f1812 HTTP/2 to HTTP/1.x headers conversion more accessible
Motivation:
Currently there is a HttpConversionUtil.addHttp2ToHttpHeaders which requires a FullHttpMessage, but this may not always be available. There is no interface that can be used with just Http2Headers and HttpHeaders.

Modifications:
- add an overload for HttpConversionUtil.addHttp2ToHttpHeaders which does not take FullHttpMessage

Result:
An overload for HttpConversionUtil.addHttp2ToHttpHeaders exists which does not require FullHttpMessage.

2dde3a386b [#3687] Correctly store WebSocketServerHandshaker in Channel attributes
Motivation:

As we stored the WebSocketServerHandshaker in the ChannelHandlerContext it was always null and so no close frame was send if WebSocketServerProtocolHandler was used.

Modifications:

Store WebSocketServerHAndshaker in the Channel attributes and so make it visibile between different handlers.

Result:

Correctly send close frame.

f89dfb0bd5 Deprecation cleanup for HTTP headers
Motivaion:
The HttpHeaders and DefaultHttpHeaders have methods deprecated due to being removed in future releases, but no replacement method to use in the current release. The deprecation policy should not be so aggressive as to not provide any non-deprecated method to use.

Modifications:
- Remove deprecated annotations and javadocs from methods which are the best we can do in terms of matching the master's api for 4.1

Result:
There should be non-deprecated methods available for HttpHeaders in 4.1.

7049d8debb Add validateHeaders and headersToLowerCase options for SPDY
Motivation:

Related to issue #4185.

HTTP has the option to disable header validation for optimisation purposes.  Introduce the same option for SPDY headers.
Also, optimise SpdyHttpEncoder by allowing the user to specify whether or not the encoder needs to convert header names to lowercase.

Modifications:

Added flags for validation and conversion.

Result:

SpdyHeader validation and conversion can be disabled.

070f1470e8 [#4185] SpdyHttpEncoder fails to convert HttpResponse to SpdyFrame
Motivation:

When SpdyHttpEncoder attempts to create an SpdyHeadersFrame from a HttpResponse an IllegalArgumentException is thrown if the original HttpResponse contains a header that includes uppercase characters. The IllegalArgumentException is thrown due to the additional validation check introduced by #4047.

Previous versions of the SPDY codec would handle this by converting the HTTP header name to lowercase before adding the header to the SpdyHeadersFrame.

Modifications:

Convert the header name to lowercase before adding it to SpdyHeaders

Result:

SpdyHttpEncoder can now convert a valid HttpResponse into a valid SpdyFrame

Motivation:
There currently exists http.HttpUtil, http2.HttpUtil, and http.HttpHeaderUtil. Having 2 HttpUtil methods can be confusing and the utilty methods in the http package could be consolidated.

Modifications:
- Rename http2.HttpUtil to http2.HttpConversionUtil
- Move http.HttpHeaderUtil methods into http.HttpUtil

Result:

Motivation:
HttpUtil.toHttp2Headers is currently not translating HTTP request headers to HTTP/2 request headers correctly.  The path, scheme, and authority are tranlation process are not respecting the HTTP/2 RFC https://tools.ietf.org/html/rfc7540#section-8.1.2.3 and HTTP RFC https://tools.ietf.org/html/rfc7230#section-5.3.

Modifications:
- path, scheme, authority must be set according to rules defined in https://tools.ietf.org/html/rfc7540#section-8.1.2.3
- HTTP/1.x URIs must be handled as defined in https://tools.ietf.org/html/rfc7230#section-5.3

Modifications:
- Add methods to distinguish request-targets as defined in https://tools.ietf.org/html/rfc7230#section-5.3

a7135e8677 HttpObjectAggregator doesn't check content-length header
Motivation:
The HttpObjectAggregator always responds with a 100-continue response. It should check the Content-Length header to see if the content length is OK, and if not responds with a 417.

Modifications:
- HttpObjectAggregator checks the Content-Length header in the case of a 100-continue.

Result:
HttpObjectAggregator responds with 417 if content is known to be too big.

e796c99b23 Add unit tests for HTTP and SPDY headers
Motivation:

When attempting to retrieve a SPDY header using an AsciiString key, if the header was inserted using a String based key, the lookup would fail. Similarly, the lookup would fail if the header was inserted with an AsciiString key, and retrieved using a String key. This has been fixed with the header simplification commit (1a43923aa8).

Extra unit tests have been added to protect against this issue occurring in the future.  The tests check that a header added using String or AsciiString can be retrieved using AsciiString or String respectively.

Modifications:

Added more unit tests

Result:

Protect against issue #4053 happening again.

b714297a44 HttpObjectDecoder half close behavior
Motivation:
In the event an HTTP message does not include either a content-length or a transfer-encoding header [RFC 7230](https://tools.ietf.org/html/rfc7230#section-3.3.3) states the behavior must be treated differently for requests and responses. If the channel is half closed then the HttpObjectDecoder is not invoking decodeLast and thus not checking if messages should be sent up the pipeline.

Modifications:
- Add comments to clarify regular decode default case.
- Handle the ChannelInputShutdownEvent in the HttpObjectDecoder and evaluate if messages need to be generated.

Result:
Messages are generated on half closed, and comments clarify existing logic.

Jakob Buchgraber
6fd0a0c55f Faster and more memory efficient headers for HTTP, HTTP/2, STOMP and SPYD. Fixes #3600
Motivation:

We noticed that the headers implementation in Netty for HTTP/2 uses quite a lot of memory
and that also at least the performance of randomly accessing a header is quite poor. The main
concern however was memory usage, as profiling has shown that a DefaultHttp2Headers
not only use a lot of memory it also wastes a lot due to the underlying hashmaps having
to be resized potentially several times as new headers are being inserted.

This is tracked as issue #3600.

Modifications:
We redesigned the DefaultHeaders to simply take a Map object in its constructor and
reimplemented the class using only the Map primitives. That way the implementation
is very concise and hopefully easy to understand and it allows each concrete headers
implementation to provide its own map or to even use a different headers implementation
for processing requests and writing responses i.e. incoming headers need to provide
fast random access while outgoing headers need fast insertion and fast iteration. The
new implementation can support this with hardly any code changes. It also comes
with the advantage that if the Netty project decides to add a third party collections library
as a dependency, one can simply plug in one of those very fast and memory efficient map
implementations and get faster and smaller headers for free.

For now, we are using the JDK's TreeMap for HTTP and HTTP/2 default headers.

Result:

- Significantly fewer lines of code in the implementation. While the total commit is still
  roughly 400 lines less, the actual implementation is a lot less. I just added some more
  tests and microbenchmarks.

- Overall performance is up. The current implementation should be significantly faster
  for insertion and retrieval. However, it is slower when it comes to iteration. There is simply
  no way a TreeMap can have the same iteration performance as a linked list (as used in the
  current headers implementation). That's totally fine though, because when looking at the
  benchmark results @ejona86 pointed out that the performance of the headers is completely
  dominated by insertion, that is insertion is so significantly faster in the new implementation
  that it does make up for several times the iteration speed. You can't iterate what you haven't
  inserted. I am demonstrating that in this spreadsheet [1]. (Actually, iteration performance is
  only down for HTTP, it's significantly improved for HTTP/2).

- Memory is down. The implementation with TreeMap uses on avg ~30% less memory. It also does not
  produce any garbage while being resized. In load tests for GRPC we have seen a memory reduction
  of up to 1.2KB per RPC. I summarized the memory improvements in this spreadsheet [1]. The data
  was generated by [2] using JOL.

- While it was my original intend to only improve the memory usage for HTTP/2, it should be similarly
  improved for HTTP, SPDY and STOMP as they all share a common implementation.

209aa28573 SPDY codec must check headers are lower case
Motivation:
The SPDY spec requires that all header names be lowercase (see https://www.chromium.org/spdy/spdy-protocol/spdy-protocol-draft3-1#TOC-3.2-HTTP-Request-Response). The SPDY codec header name validator does not enforce this requirement.

Modifications:
- SpdyCodecUtil.validateHeaderName should check for upper case characters and throw an error if any are found.

Result:
SPDY codec header validation enforces specification requirement.

b958263853 Send full response for unsupported websocket versions
Motivation:

WebSocketServerHandshakerFactory.sendUnsupportedVersionResponse does not
send a LastHttpContent, nor does it flush, and it doesn't send a content
length.

Modifications:

Changed sendUnsupportedVersionResponse to send FullHttpResponse, to
writeAndFlush, and to set a content length of 0. Also added a test for
this method.

Result:

Upstream handlers will be able to determine the end of the response, the
response will actually get written to the client, and the client will be
able to determine the end of the response.

caa1505020 Get uploaded size while upload is in progress
Proposal to fix issue #3636

Motivations:
Currently, while adding the next buffers to the decoder
(`decoder.offer()`), there is no way to access to the current HTTP
object being decoded since it can only be available currently once fully
decoded by `decoder.hasNext()`.
Some could want to know the progression on the overall transfer but also
per HTTP object.
While overall progression could be done using (if available) the global
Content-Length of the request and taking into account each HttpContent
size, the per HttpData object progression is unknown.

Modifications:
1) For HTTP object, `AbstractHttpData` has 2 protected properties named
`definedSize` and `size`, respectively the supposely final size and the
current (decoded until now) size.
This provides a new method `definedSize()` to get the current value for
`definedSize`. The `size` attribute is reachable by the `length()`
method.

Note however there are 2 different ways that currently managed the
`definedSize`:
a) `Attribute`: it is reset each time the value is less than actual
(when a buffer is added, the value is increased) since the final length
is not known (no Content-Length)
b) `FileUpload`: it is set at startup from the lengh provided

So these differences could lead in wrong perception;
a) `Attribute`: definedSize = size always
b) `FileUpload`: definedSize >= size always

Therefore the comment tries to explain clearly the different behaviors.

2) In the InterfaceHttpPostRequestDecoder (and the derived classes), I
add a new method: `decoder.currentPartialHttpData()` which will return a
`InterfaceHttpData` (if any) as the current `Attribute` or `FileUpload`
(the 2 generic types), which will allow then the programmer to check
according to the real type (instance of) the 2 methods `definedSize()`
and `length()`.

This method check if currentFileUpload or currentAttribute are null and
returns the one (only one could be not null) that is not null.

Note that if this method returns null, it might mean 2 situations:
a) the last `HttpData` (whatever attribute or file upload) is already
finished and therefore accessible through `next()`
b) there is not yet any `HttpData` in decoding (body not yet parsed for
instance)

Result:
The developper has more access and therefore control on the current
upload.
The coding from developper side could looks like in the example in
HttpUloadServerHandler.

0ca65f1373 Lazily instantiate HttpServerUpgradeHandler.UpgradeCodec
Related: #3814

Motivation:

To implement the support for an upgrade from cleartext HTTP/1.1
connection to cleartext HTTP/2 (h2c) connection, a user usually uses
HttpServerUpgradeHandler.

It does its job, but it requires a user to instantiate the UpgradeCodecs
for all supported protocols upfront. It means redundancy for the
connections that are not upgraded.

Modifications:

- Change the constructor of HttpServerUpgradeHandler
  - Accept UpgraceCodecFactory instead of UpgradeCodecs
- The default constructor of HttpServerUpgradeHandler sets the
  maxContentLength to 0 now, which shouldn't be a problem because a
  usual upgrade request is a GET.
- Update the examples accordingly

Result:

A user can instantiate Http2ServerUpgradeCodec and its related objects
(Http2Connection, Http2FrameReader/Writer, Http2FrameListener, etc) only
when necessary.

afb46b926f Improve the API design of Http2OrHttpChooser and SpdyOrHttpChooser
Related: #3641 and #3813

Motivation:

When setting up an HTTP/1 or HTTP/2 (or SPDY) pipeline, a user usually
ends up with adding arbitrary set of handlers.

Http2OrHttpChooser and SpdyOrHttpChooser have two abstract methods
(create*Handler()) that expect a user to return a single handler, and
also have add*Handlers() methods that add the handler returned by
create*Handler() to the pipeline as well as the pre-defined set of
handlers.

The problem is, some users (read: I) don't need all of them or the
user wants to add more than one handler. For example, take a look at
io.netty.example.http2.tiles.Http2OrHttpHandler, which works around
this issue by overriding addHttp2Handlers() and making
createHttp2RequestHandler() a no-op.

Modifications:

- Replace add*Handlers() and create*Handler() with configure*()
- Rename getProtocol() to selectProtocol() to make what it does clear
- Provide the default implementation of selectProtocol()
- Remove SelectedProtocol.UNKNOWN and use null instead, because
  'UNKNOWN' is not a protocol
- Proper exception handling in the *OrHttpChooser so that the
  exception is logged and the connection is closed when failed to
  select a protocol
- Make SpdyClient example always use SSL. It was always using SSL
  anyway.
- Implement SslHandshakeCompletionEvent.toString() for debuggability
- Remove an orphaned class: JettyNpnSslSession
- Add SslHandler.applicationProtocol() to get the name of the
  application protocol
  - SSLSession.getProtocol() now returns transport-layer protocol name
    only, so that it conforms to its contract.

Result:

- *OrHttpChooser have better API.
- *OrHttpChooser handle protocol selection failure properly.
- SSLSession.getProtocol() now conforms to its contract.
- SpdyClient example works with SpdyServer example out of the box

757671b7cc Support empty http responses when using compression
Motivation:

Found a bug in that netty would generate a 20 byte body when returing a response
to an HTTP HEAD. the 20 bytes seems to be related to the compression footer.

RFC2616, section 9.4 states that responses to an HTTP HEAD MUST not return a message
body in the response.

Netty's own client implementation expected an empty response. The extra bytes lead to a
2nd response with an error decoder result:
java.lang.IllegalArgumentException: invalid version format: 14

Modifications:

Track the HTTP request method. When processing the response we determine if the response
is passthru unnchanged. This decision now takes into account the request method and passthru
responses related to HTTP HEAD requests.

Result:

Netty's http client works and better RFC conformance.
