cf8f6e3e2f [#5861] HttpUtil.getContentLength(HttpMessage, long) throws unexpected NumberFormatException
Motivation:

The Javadocs of HttpUtil.getContentLength(HttpMessage, long) and its int overload state that the provided default value is returned if the Content-Length value is not a number. NumberFormatException is thrown instead.

Modifications:

Correctly handle when the value is not a number.

Result:

API works as stated in javadocs.

dd1ba2a252 HttpObjectDecoder resetRequested not updated after reset
Motivation:
HttpObjectDecoder maintains a resetRequested flag which is used to determine if internal state should be reset when a decode occurs. However after a reset is done the resetRequested flag is not set to false. This leads to all data after this point being discarded.

Modifications:
- Set resetRequested to false when a reset is done

Result:
HttpObjectDecoder can still function after a reset.

c57d4bed91 Add HttpServerKeepAliveHandler
Motivation:

As discussed in #5738, developers need to concern themselves with setting
connection: keep-alive on the response as well as whether to close a
connection or not after writing a response.  This leads to special keep-alive
handling logic in many different places.  The purpose of the HttpServerKeepAliveHandler
is to allow developers to add this handler to their pipeline and therefore
free themselves of having to worry about the details of how Keep-Alive works.

Modifications:

Added HttpServerKeepAliveHandler to the io.netty.handler.codec.http package.

Result:

Developers can start using HttpServerKeepAliveHandler in their pipeline instead
of worrying about when to close a connection for keep-alive.

245fb52c90 Provide extra info together with handshake complete event.
Motivation:

As described in #5734

Before this change, if the server had to do some sort of setup after a
handshake was completed based on handshake's information, the only way
available was to wait (in a separate thread) for the handshaker to be
added as an attribute to the channel. Too much hassle.

Modifications:

Handshake completed event need to be stateful now, so I've added a tiny
class holding just the HTTP upgrade request and the selected subprotocol
which is fired as an event after the handshake has finished.
I've also deprecated the old enum used as stateless event and I left the
code that fires it for backward compatibility. It should be removed in
the next mayor release.

Result:

It should be much simpler now to do initialization stuff based on
subprotocol or request headers on handshake completion. No asynchronous
waiting needed anymore.

e3aca1f3d6 CorsHandler to respect http connection (keep-alive) header.
Motivation:

The CorsHandler currently closes the channel when it responds to a preflight (OPTIONS)
request or in the event of a short circuit due to failed validation.

Especially in an environment where there's a proxy in front of the service this causes
unnecessary connection churn.

Modifications:

CorsHandler now uses HttpUtil to determine if the connection should be closed
after responding and to set the Connection header on the response.

Result:

Channel will stay open when the CorsHandler responds unless the client specifies otherwise
or the protocol version is HTTP/1.0

f6c16f4897 Attempt at improving docs in HttpObjectAggregator
Motivation:

Documentation was added in #2401 to aid developers in understanding
how HttpObjectAggregator works and that it needs an encoder before it.

In #2471 it was pointed out that the documentation added can actually
add to the confusion and that it might have a typo.

This is an attempt at clearing up that confusion.  Feedback is welcome.

Modifications:

- Adjust class level javadoc for HttpObjectAggregator
  * Remove reference to HttpRequestEncoder
  * Point out when HttpResponseEncoder is needed
  * Point out that either HttpRequestDecoder or HttpResponseDecoder is needed
  * Make clear everything must be added before HttpObjectAggregator
  * Mention HttpServerCodec

Result:

Avoid confusion about dependencies for HttpObjectAggregator on the pipeline.

3451b3cbb3 Cookie name must be case sensitive
Motivation:

RFC 6265 does not state that cookie names must be case insensitive.

Modifications:

Fix io.netty.handler.codec.http.cookie.DefaultCookie#equals() method to
use case sensitive String#equals() and String#compareTo().

Result:

It is possible to parse several cookies with same names but with
different cases.

8d043cc4dd Do not return Access-Control-Allow-Headers on Non-Preflight Cors requests
Motivation:

The CorsHandler currently returns the Access-Control-Allow-Headers
header as on a Non-Preflight CORS request (Simple request).
As per the CORS specification the Access-Control-Allow-Headers header
should only be returned on Preflight requests. (not on simple requests).

https://www.w3.org/TR/2014/REC-cors-20140116/#access-control-allow-headers-response-header

http://www.html5rocks.com/static/images/cors_server_flowchart.png

Modifications:

Modified CorsHandler.java to not add the Access-Control-Allow-Headers
header when responding to Non-preflight CORS request.

Result:

Access-Control-Allow-Headers header will not be returned on a Simple
request (Non-preflight CORS request).

82b617dfe9 retainSlice() unwrap ByteBuf
Motivation:
retainSlice() currently does not unwrap the ByteBuf when creating the ByteBuf wrapper. This effectivley forms a linked list of ByteBuf when it is only necessary to maintain a reference to the unwrapped ByteBuf.

Modifications:
- retainSlice() and retainDuplicate() variants should only maintain a reference to the unwrapped ByteBuf
- create new unit tests which generally verify the retainSlice() behavior
- Remove unecessary generic arguments from AbstractPooledDerivedByteBuf
- Remove unecessary int length member variable from the unpooled sliced ByteBuf implementation
- Rename the unpooled sliced/derived ByteBuf to include Unpooled in their name to be more consistent with the Pooled variants

Result:
Fixes https://github.com/netty/netty/issues/5582

835f901d5f Fix #5590 QueryStringDecoder#path should decode the path info
Motivation:

Currently, QueryStringDecoder#path simply returns the path info as is, without decoding it as the Javadoc states.

Modifications:

* Make QueryStringDecoder#path decode the path info.
* Add tests to QueryStringDecoderTest.

Result:

QueryStringDecoder#path now decodes the path info as expected.

009680488e Fix set100ContinueExpected(...) jsvadoc
Motivation:

We don't have an argument named {@code value} but have {@code set} and
{@code expected} in HttpHeaders and HttpUtil respectively.

Modifications:

I replaced {@code value} to {@code set} and {@code expected} in HttpHeaders
and HttpUtil respectively.

Result:

Now javadoc says;
If {@code set} is {@code true}, the {@code "Expect: 100-continue"} header is
set and all other previous {@code "Expect"} headers are removed. Otherwise,
all {@code "Expect"} headers are removed completely. in HttpHeaders

If {@code expected} is {@code true}, the {@code "Expect: 100-continue"} header
is set and all other previous {@code "Expect"} headers are removed. Otherwise,
all {@code "Expect"} headers are removed completely. in HttpUtil

d964bf6f18 Remove usages of deprecated methods group() and childGroup().
Motivation:

These methods were recently deprecated. However, they remained in use in several locations in Netty's codebase.

Modifications:

Netty's code will now access the bootstrap config to get the group or child group.

Result:

No impact on functionality.

e845670043 Set some StackTraceElement on pre-instantiated static exceptions
Motivation:

We use pre-instantiated exceptions in various places for performance reasons. These exceptions don't include a stacktrace which makes it hard to know where the exception was thrown. This is especially true as we use the same exception type (for example ChannelClosedException) in different places. Setting some StackTraceElements will provide more context as to where these exceptions original and make debugging easier.

Modifications:

Set a generated StackTraceElement on these pre-instantiated exceptions which at least contains the origin class and method name. The filename and linenumber are specified as unkown (as stated in the javadocs of StackTraceElement).

Result:

Easier to find the origin of a pre-instantiated exception.

- Add unit tests.

Result:

ee0897a1d9 HttpContentDecompressor should change decompressed requests to chunked encoding. Fixes issue #5428
`HttpContentDecoder` was removing `Content-Length` header but not adding a `Transfer-Encoding` header which goes against the HTTP spec.

Added `Transfer-Encoding` header with value `chunked` when `Content-Length` is removed.
Modified existing unit test to also check for this condition.

Compliance with HTTP spec.

4a1e0ceb4d [5382] HttpContentEncoder should not set chunked transfer-encoding for HTTP/1.0
Motivation:

When using HttpContentCompressor and the HttpResponse is protocol version 1.0, HttpContentEncoder.encode() should not set the transfer-encoding header to chunked. Chunked transfer-encoding is not valid for HTTP 1.0 - this causes ERR_CONTENT_DECODING_FAILED errors in chrome and similar failures in IE.

Modifications:

Skip HTTP/1.0 messages

Result:

Be able to serve HTTP/1.0 as well when HttpContentEncoder is in the pipeline.

f5eea4698d Fix possible NPE in HttpCunkedInput if wrapped ChunkedInput.readChunk(...) return null.
Motivation:

Its completly fine for ChunkedInput.readChunk(...) to return null to indicate there is currently not any data to read. We need to handle this in HttpChunkedInput to not produce a NPE when constructing the HttpContent.

Modifications:

If readChunk(...) return null just return null as well.

Result:

No more NPE.

328a1ec01b cleanup from 819b26b
Motivation:
I cherry-picked 819b26b too soon. There were entries added to a deprecated class which should only go into the non-deprecated version of the class.

Modifications:
- Remove the static final variables that were added as duplicates to the deprecated class

Result:
Deprecated code does not grown in volume without need.

- Add constants for "gzip,deflate" Content-Encoding

Result:
More HttpHeader values constants available, both in
`HttpHeaders.Values` and `HttpHeaderValues`.

c3abb9146e Use shaded dependency on JCTools instead of copy and paste
Motivation:
JCTools supports both non-unsafe, unsafe versions of queues and JDK6 which allows us to shade the library in netty-common allowing it to stay "zero dependency".

Modifications:
- Remove copy paste JCTools code and shade the library (dependencies that are shaded should be removed from the <dependencies> section of the generated POM).
- Remove usage of OneTimeTask and remove it all together.

Result:
Less code to maintain and easier to update JCTools and less GC pressure as the queue implementation nt creates so much garbage

398efb1f71 Ensure valid message sequence if channel is closed before receive headers.
Motivation:

When the channel is closed while we still decode the headers we currently not preserve correct message sequence. In this case we should generate an invalid message with a current cause.

Modifications:

Create an invalid message with a PrematureChannelClosureException as cause when the channel is closed while we decode the headers.

Result:

Correct message sequence preserved and correct DecoderResult if the channel is closed while decode headers.

844976a0a2 Ensure the same ByteBufAllocator is used in the EmbeddedChannel when compress / decompress. Related to [#5294]
Motivation:

The user may specify to use a different allocator then the default. In this case we need to ensure it is shared when creating the EmbeddedChannel inside of a ChannelHandler

Modifications:

Use the config of the "original" Channel in the EmbeddedChannel and so share the same allocator etc.

Result:

Same type of buffers are used.

7b25402e80 Add CompositeByteBuf.addComponent(boolean ...) method to simplify usage
Motivation:

At the moment the user is responsible to increase the writer index of the composite buffer when a new component is added. We should add some methods that handle this for the user as this is the most popular usage of the composite buffer.

Modifications:

Add new methods that autoamtically increase the writerIndex when buffers are added.

Result:

Easier usage of CompositeByteBuf.

1cb706ac93 HTTP/2 HPACK Header Name Validation and Trailing Padding
Motivation:
The HPACK code currently disallows empty header names. This is not explicitly forbidden by the HPACK RFC https://tools.ietf.org/html/rfc7541. However the HTTP/1.x RFC https://tools.ietf.org/html/rfc7230#section-3.2 and thus HTTP/2 both disallow empty header names, and so this precondition check should be moved from the HPACK code to the protocol level.
HPACK also requires that string literals which are huffman encoded must be treated as an encoding error if the string has more than 7 trailing padding bits https://tools.ietf.org/html/rfc7541#section-5.2, but this is currently not enforced.

Result:
- HPACK to allow empty header names
- HTTP/1.x and HTTP/2 header validation should not allow empty header names
- Enforce max of 7 trailing padding bits

Result:
Code is more compliant with the above mentioned RFCs

3a9f472161 Make retained derived buffers recyclable
Related: #4333 #4421 #5128

Motivation:

slice(), duplicate() and readSlice() currently create a non-recyclable
derived buffer instance. Under heavy load, an application that creates a
lot of derived buffers can put the garbage collector under pressure.

Modifications:

- Add the following methods which creates a non-recyclable derived buffer
  - retainedSlice()
  - retainedDuplicate()
  - readRetainedSlice()
- Add the new recyclable derived buffer implementations, which has its
  own reference count value
- Add ByteBufHolder.retainedDuplicate()
- Add ByteBufHolder.replace(ByteBuf) so that..
  - a user can replace the content of the holder in a consistent way
  - copy/duplicate/retainedDuplicate() can delegate the holder
    construction to replace(ByteBuf)
- Use retainedDuplicate() and retainedSlice() wherever possible
- Miscellaneous:
  - Rename DuplicateByteBufTest to DuplicatedByteBufTest (missing 'D')
  - Make ReplayingDecoderByteBuf.reject() return an exception instead of
    throwing it so that its callers don't need to add dummy return
    statement

Result:

Derived buffers are now recycled when created via retainedSlice() and
retainedDuplicate() and derived from a pooled buffer

0557927b65 Updating allowNullOrigin to return 'null' instead of '*'.
Motivation:
Currently the way a 'null' origin, a request that most often indicated
that the request is coming from a file on the local file system, is
handled is incorrect. We are currently returning a wildcard origin '*'
but should be returning 'null' for the 'Access-Control-Allow-Origin'
which is valid according to the specification [1].

Modifications:
Updated CorsHandler to add a 'null' origin instead of the '*' origin in
the case the request origin is 'null.

Result:
All test pass and the CORS example as does the cors.html example if you
try to serve it by opening the file directly in a web browser.

0035630bd0 We need to ensure we correct reset decoder in decodeLast() to not produce multiple LastHttpContent instances.
