Motivation:
If the wsURL contains an encoded query, it will be decoded when generating the raw path. For example if the wsURL is http://test.org/path?a=1%3A5, the returned raw path would be /path?a=1:5
Modifications:
Use wsURL.getRawQuery() rather than wsURL.getQuery()
Result:
rawPath will now return /path?a=1%3A5
Motivation:
Some commons values are missing from HttpHeader values constants.
Modifications:
- Add constants for "application/json" Content-Type
- Add constants for "gzip,deflate" Content-Encoding
Result:
More HttpHeader values constants available, both in
`HttpHeaders.Values` and `HttpHeaderValues`.
Motivation:
The HttpObjectAggregator never appends a 'Connection: close' header to
the response of oversized messages even though in the majority of cases
its going to close the connection.
Modification:
This PR addresses that by ensuring the requisite header is present when
the connection is going to be closed.
Result:
Gracefully signal that we are about to close the connection.
Motivation:
We need to ensure we not add the Transfer-Encoding header if the HttpMessage is EOF terminated.
Modifications:
Only add the Transfer-Encoding header if an Content-Length header is present.
Result:
Correctly handle HttpMessage that is EOF terminated.
Motivation:
We want to reject the upgrade as quickly as possible, so that we can
support streamed responses.
Modifications:
Reject the upgrade as soon as we inspect the headers if they're wrong,
instead of waiting for the entire response body.
Result:
If a remote server doesn't know how to use the http upgrade and tries to
responsd with a streaming response that never ends, the client doesn't
buffer forever, but can instead pass it along. Fixes#5954
Motivation:
the build doesnt seem to enforce this, so they piled up
Modifications:
removed unused import lines
Result:
less unused imports

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.
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.
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.
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.
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
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.

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.
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-headerhttp://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).
Motivation:
There are few duplicated byte[] CRLF fields in code.
Modifications:
Removed duplicated fields as they could be inherited from parent encoder.
Result:
Less static fields.
Motivation :
Unboxing operations allocate unnecessary objects when it could be avoided.
Modifications:
Replaced Float.valueOf with Number.parseFloat where possible.
Result:
Less unnecessary objects allocations.
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
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.
Motivation:
DiskFileUpload and MemoryFileUpload.equals(...) are broken.
Modifications:
Fix implementation and add unit test.
Result:
Equals method are correct now.
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
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.
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.
Motivation:
When HTTPS is used we should use https in the sec-websocket-origin / origin header
Modifications:
- Correctly generate the sec-websocket-origin / origin header
- Add unit tests.
Result:
Generate correct header.
`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.
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.
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.
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.
Motivation:
Some commons values are missing from HttpHeader values constants.
Modifications:
- Add constants for "application/json" Content-Type
- Add constants for "gzip,deflate" Content-Encoding
Result:
More HttpHeader values constants available, both in
`HttpHeaders.Values` and `HttpHeaderValues`.
Motivation:
Support fetches data chunk by chunk for use with WebSocket chunked transfers.
Modifications:
Create a WebSocketChunkedInput.java that add to io.netty.handler.codec.http.websocketx package
Result:
The WebSocket transfers/fetches data chunk by chunk.
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
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.
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.
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.
