944e11c065 Add unit to maxContentLength javadoc of HttpObjectAggregator
Motivation:
Not knowing which unit is used for the maxContentLength of the HttpObjectAggregator when reading the Javadoc is annoying and can be a source of bugs.

Modifications:
Added the mention "in bytes"

Result:
Javadoc is clear.

6d5c38897e Fix header and initial line length counting
Related: #3445

Motivation:

HttpObjectDecoder.HeaderParser does not reset its counter (the size
field) when it failed to find the end of line.  If a header is split
into multiple fragments, the counter is increased as many times as the
number of fragments, resulting an unexpected TooLongFrameException.

Modifications:

- Add test cases that reproduces the problem
- Reset the HeaderParser.size field when no EOL is found.

Result:

One less bug

5b1b334f01 When null origin is supported then credentials header must not be set.
Motivation:
Currently CORS can be configured to support a 'null' origin, which can
be set by a browser if a resources is loaded from the local file system.
When this is done 'Access-Control-Allow-Origin' will be set to "*" (any
origin). There is also a configuration option to allow credentials being
sent from the client (cookies, basic HTTP Authentication, client side
SSL). This is indicated by the response header
'Access-Control-Allow-Credentials' being set to true. When this is set
to true, the "*" origin is not valid as the value of
'Access-Control-Allow-Origin' and a browser will reject the request:
http://www.w3.org/TR/cors/#resource-requests

Modifications:
Updated CorsHandler's setAllowCredentials to check the origin and if it
is "*" then it will not add the 'Access-Control-Allow-Credentials'
header.

Result:
Is is possible to have a client send a 'null' origin, and at the same
time have configured the CORS to support that and to allow credentials
in that combination.

c53b8d5a85 Suggestion for supporting single header fields.
Motivation:
At the moment if you want to return a HTTP header containing multiple
values you have to set/add that header once with the values wanted. If
you used set/add with an array/iterable multiple HTTP header fields will
be returned in the response.

Note, that this is indeed a suggestion and additional work and tests
should be added. This is mainly to bring up a discussion.

Modifications:
Added a flag to specify that when multiple values exist for a single
HTTP header then add them as a comma separated string.
In addition added a method to StringUtil to help escape comma separated
value charsequences.

Result:
Allows for responses to be smaller.

afa9e71ed3 Allow to use WebSocketClientHandshaker and WebSocketServerHandshaker with HttpResponse / HttpRequest
Motivation:

To use WebSocketClientHandshaker / WebSocketServerHandshaker it's currently a requirement of having a HttpObjectAggregator in the ChannelPipeline. This is not a big deal when a user only wants to server WebSockets but is a limitation if the server serves WebSockets and normal HTTP traffic.

Modifications:

Allow to use WebSocketClientHandshaker and WebSocketServerHandshaker without HttpObjectAggregator in the ChannelPipeline.

Result:

More flexibility

86cb41bf95 Possible leak in AbstractDiskHttpData
Motivation:
SonarQube (clinker.netty.io/sonar) reported a resource which may not have been properly closed in all situations in AbstractDiskHttpData.

Modifications:
- Ensure file channels are closed in the presence of exceptions.
- Correct instances where local channels were created but potentially not closed.

Result:
Less leaks. Less SonarQube vulnerabilities.

b19a12b952 Fixes #3362 (Possible wrong behavior in HttpResponseDecoder/HttpRequestDecoder for large header/initline/content)
Motivation:

`HttpResponseDecoder` and `HttpRequestDecoder` in the event when the max configured sizes for HTTP initial line, headers or content is breached, sends a `DefaultHttpResponse` and `DefaultHttpRequest` respectively. After this `HttpObjectDecoder` gets into `BAD_MESSAGE` state and ignores any other data received on this connection.
The combination of the above two behaviors, means that the decoded response/request are not complete (absence of sending `LastHTTPContent`). So, any code, waiting for a complete message will have to additionally check for decoder result to follow the correct semantics of HTTP.

If `HttpResponseDecoder` and `HttpRequestDecoder` creates a Full* invalid message then the request/response is a complete HTTP message and hence obeys the HTTP contract.

Modification:

Modified `HttpRequestDecoder`, `HttpResponseDecoder`, `RtspRequestDecoder` and  `RtspResponseDecoder` to return Full* messages from `createInvalidMessage()`

Result:

Fixes the wrong behavior of sending incomplete messages from these codecs

3c6cbd40e2 Fix an sporadic failure in ServerCookieEncoderTest
In testEncodingSingleCookieV0():

Let's assume we encoded a cookie with MaxAge=50 when currentTimeMillis
is 10999.

Because the encoder will not encode the millisecond part for Expires,
the timeMillis value of the encoded Expires field will be 60000. (If we
did not dropped the millisecond part, it would be 60999.)

Encoding a cookie will take some time, so currentTimeMillis will
increase slightly, such as to 11001.

  diff = (60000 - 11001) / 1000 = 48999 / 1000 = 48
  maxAge - diff = 50 - 48 = 2

Due to losing millisecond part twice, we end up with the precision
problem illustrated above, and thus we should increase the tolerance
from 1 second to 2 seconds.

2d24e1f27d Back port HTTP/2 codec from master to 4.1
Motivation:

HTTP/2 codec was implemented in master branch.
Since, master is not yet stable and will be some time before it gets released, backporting it to 4.1, enables people to use the codec with a stable netty version.

Modification:

The code has been copied from master branch as is, with minor modifications to suit the `ChannelHandler` API in 4.x.
Apart from that change, there are two backward incompatible API changes included, namely,

- Added an abstract method:

  `public abstract Map.Entry<CharSequence, CharSequence> forEachEntry(EntryVisitor<CharSequence> visitor)
            throws Exception;`

to `HttpHeaders` and implemented the same in `DefaultHttpHeaders` as a delegate to the internal `TextHeader` instance.

- Added a method:

`FullHttpMessage copy(ByteBuf newContent);`

in `FullHttpMessage` with the implementations copied from relevant places in the master branch.

- Added missing abstract method related to setting/adding short values to `HttpHeaders`

Result:

HTTP/2 codec can be used with netty 4.1

ed10513238 Fixed several issues with HttpContentDecoder
Motivation:

HttpContentDecoder had the following issues:
- For chunked content, the decoder set invalid "Content-Length" header
	with length of the first decoded chunk.
- Decoding of FullHttpRequests put both the original conent and decoded
	content into output. As result, using HttpObjectAggregator before the
	decoder lead to errors.
- Requests with "Expect: 100-continue" header were not acknowleged:
	the decoder didn't pass the header message down the handler's chain
	until content is received. If client expected "100 Continue" response,
	deadlock happened.

Modification:

- Invalid "Content-Length" header is removed; handlers down the chain can either
	rely on LastHttpContent message or ask HttpObjectAggregator to add the header.
- FullHttpRequest is split into HttpRequest and HttpContent (decoded) parts.
- Header (HttpRequest) part of request is sent down the chain as soon as it's received.

Result:

The issues are fixed, unittest is added.

Motivation:

Rfc6265Client/ServerCookieEncoder is a better replacement of the old
Client/ServerCookieEncoder, and thus there's no point of keeping both.

Modifications:

- Remove the old Client/ServerCookieEncoder
- Remove the 'Rfc6265' prefix from the new cookie encoder/decoder
  classes
- Deprecate CookieDecoder

Result:

c298230128 RFC6265 cookies support
Motivation:

Currently Netty supports a weird implementation of RFC 2965.
First, this RFC has been deprecated by RFC 6265 and nobody on the
internet use this format.

Then, there's a confusion between client side and server side encoding
and decoding.

Typically, clients should only send name=value pairs.

This PR introduces RFC 6265 support, but keeps on supporting RFC 2965 in
the sense that old unused fields are simply ignored, and Cookie fields
won't be populated. Deprecated fields are comment, commentUrl, version,
discard and ports.

It also provides a mechanism for safe server-client-server roundtrip, as
User-Agents are not supposed to interpret cookie values but return them
as-is (e.g. if Set-Cookie contained a quoted value, it should be sent
back in the Cookie header in quoted form too).

Also, there are performance gains to be obtained by not allocating the
attribute name Strings, as we only want to match them to find which POJO
field to populate.

Modifications:

- New RFC6265ClientCookieEncoder/Decoder and
  RFC6265ServerCookieEncoder/Decoder pairs that live alongside old
  CookieEncoder/Decoder pair to not break backward compatibility.
- New Cookie.rawValue field, used for lossless server-client-server
  roundtrip.

Result:

RFC 6265 support.
Clean separation of client and server side.

Decoder performance gain:

04dd885421 SPDY: fix support for pushed resources in SpdyHttpEncoder
Motivation:

The SpdyHttpDecoder was modified to support pushed resources that are
divided into multiple frames. The decoder accepts a pushed
SpdySynStreamFrame containing the request headers, followed by a
SpdyHeadersFrame containing the response headers.

Modifications:

This commit modifies the SpdyHttpEncoder so that it encodes pushed
resources in a format that the SpdyHttpDecoder can decode. The encoder
will accept an HttpRequest object containing the request headers,
followed by an HttpResponse object containing the response headers.

Result:

The SpdyHttpEncoder will create a SpdySynStreamFrame followed by a
SpdyHeadersFrame when sending pushed resources.

85fecba770 Fix for Issue #3308 related to slice missing retain
Motivations:
It seems that slicing a buffer and using this slice to write to CTX will
decrease the initial refCnt to 0, while the original buffer is not yet
fully used (not empty).

Modifications:
As suggested in the ticket and tested, when the currentBuffer is sliced
since it will still be used later on, the currentBuffer is retained.

Add a test case for this issue.

Result:
The currentBuffer still has its correct refCnt when reaching the last
write (not sliced) of 1 and therefore will be released correctly.
The exception does no more occur.

This fix should be applied to all branches >= 4.0.

f0e306c2fd Allow to override how headers are encoded
Motivation:

Even if its against the HTTP RFC there are situations where it may be useful to use other chars then US_ASCII in the headers. We should allow to make it possible by allow the user to override the how headers are encoded.

Modifications:

- Add encodeHeaders(...) method and so allow to override it.

Result:

It's now possible to encode headers with other charset then US_ASCII by just extend the encoder and override the encodeHeaders(...) method.

5ba4fdf3ba HttpObjectAggregator only set Content-Length is not already set.
Motivation:

HEAD requests will have a Content-Length set that doesn't match the
actual length. So we only want to set Content-Length header if it isn't
already set.

Modifications:

If check around setting the Content-Length.

Result:

A HEAD request will no correctly return the specified Content-Length
instead of the body length.

defined in the RFC 2616:

- Information 1xx
- Success 2xx
- Redirection 3xx
- Client Error 4xx
- Server Error 5xx

- Add HttpStatusClass
- Add HttpResponseStatus.codeClass() that returns the class of the HTTP
  status code

3ebc1ab321 Adding codeAsText to HttpResponseStatus.
Motivation:

I found myself writing AsciiString constants in my code for
response statuses and thought that perhaps it might be nice to have
them defined by Netty instead.

Modifications:

Adding codeAsText to HttpResponseStatus that returns the status code as
AsciiText.

In addition, added the 421 Misdirected Request response code from
https://tools.ietf.org/html/draft-ietf-httpbis-http2-15#section-9.1.2

This response header was renamed in draft 15:
https://tools.ietf.org/html/draft-ietf-httpbis-http2-15#appendix-A.1
But the code itself was not changed, and I thought using the latest would
be better.

Result:

It is now possible to specify a status like this:
new DefaultHttp2Headers().status(HttpResponseStatus.OK.codeAsText());

35db3c6710 Small performance improvements
Motivation:

Found performance issues via FindBugs and PMD.

Modifications:

- Removed unnecessary boxing/unboxing operations in DefaultTextHeaders.convertToInt(CharSequence) and DefaultTextHeaders.convertToLong(CharSequence). A boxed primitive is created from a string, just to extract the unboxed primitive value.
- Added a static modifier for DefaultHttp2Connection.ParentChangedEvent class. This class is an inner class, but does not use its embedded reference to the object which created it. This reference makes the instances of the class larger, and may keep the reference to the creator object alive longer than necessary.
- Added a static compiled Pattern to avoid compile it each time it is used when we need to replace some part of authority.
- Improved using of StringBuilders.

Result:

Performance improvements.

6f80fdcac4 SPDY: add support for pushed resources in SpdyHttpDecoder
Motivation:

The SPDY/3.1 spec does not adequate describe how to push resources
from the server. This was solidified in the HTTP/2 drafts by dividing
the push into two frames, a PushPromise containing the request,
followed by a Headers frame containing the response.

Modifications:

This commit modifies the SpdyHttpDecoder to support pushed resources
that are divided into multiple frames. The decoder will accept a
pushed SpdySynStreamFrame containing the request headers, followed by
a SpdyHeadersFrame containing the response headers.

Result:

The SpdyHttpDecoder will create an HttpRequest object followed by an
HttpResponse object when receiving pushed resources.

1db8b83d22 Cater for empty response bodies when performing response compression.
Motivation:
RFC 2616, 4.3 Message Body states that:
All 1xx (informational), 204 (no content), and 304 (not modified) responses MUST NOT include a
message-body. All other responses do include a message-body, although it MAY be of zero length.

Modifications:
HttpContentEncoder was previously modified to cater for HTTP 100 responses. This check is enhanced to
include HTTP 204 and 304 responses.

Result:
Empty response bodies will not be modified to include the compression footer. This footer messed with Chrome's
response parsing leading to "hanging" requests.

Modifications:

- Changed super class of HttpObjectDecoder from ReplayDecoder to ByteToMessageDecoder.
- Rewrote decode() method of HttpObjectDecoder to use proper state machine.
- Changed private methods HeaderParser.parse(ByteBuf), readHeaders(ByteBuf) and readTrailingHeaders(ByteBuf), skipControlCharacters(ByteBuf) to consider available bytes.
- Set HeaderParser and LineParser as static inner classes.
- Replaced not safe actualReadableBytes() with buffer.readableBytes().

72a611a28f HTTP Content Encoder allow EmptyLastHttpContent
Motiviation:
The HttpContentEncoder does not account for a EmptyLastHttpContent being provided as input.  This is useful in situations where the client is unable to determine if the current content chunk is the last content chunk (i.e. a proxy forwarding content when transfer encoding is chunked).

Modifications:
- HttpContentEncoder should not attempt to compress empty HttpContent objects

Result:
HttpContentEncoder supports a EmptyLastHttpContent to terminate the response.

4ce994dd4f Fix backward compatibility from the previous backport
Motivation:

The commit 50e06442c3 changed the type of
the constants in HttpHeaders.Names and HttpHeaders.Values, making 4.1
backward-incompatible with 4.0.

It also introduces newer utility classes such as HttpHeaderUtil, which
deprecates most static methods in HttpHeaders.  To ease the migration
between 4.1 and 5.0, we should deprecate all static methods that are
non-existent in 5.0, and provide proper counterpart.

Modification:

- Revert the changes in HttpHeaders.Names and Values
- Deprecate all static methods in HttpHeaders in favor of:
  - HttpHeaderUtil
  - the member methods of HttpHeaders
  - AsciiString
- Add integer and date access methods to HttpHeaders for easier future
  migration to 5.0
- Add HttpHeaderNames and HttpHeaderValues which provide standard HTTP
  constants in AsciiString
  - Deprecate HttpHeaders.Names and Values
  - Make HttpHeaderValues.WEBSOCKET lowercased because it's actually
    lowercased in all WebSocket versions but the oldest one
- Add RtspHeaderNames and RtspHeaderValues which provide standard RTSP
  constants in AsciiString
  - Deprecate RtspHeaders.*
- Do not use AsciiString.equalsIgnoreCase(CharSeq, CharSeq) if one of
  the parameters are AsciiString
- Avoid using AsciiString.toString() repetitively
  - Change the parameter type of some methods from String to
    CharSequence

Result:

Backward compatibility is recovered.  New classes and methods will make
the migration to 5.0 easier, once (Http|Rtsp)Header(Names|Values) are
ported to master.

7fbd66f814 Added an option to use websockets without masking
Motivation:

The requirement for the masking of frames and for checks of correct
masking in the websocket specifiation have a large impact on performance.
While it is mandatory for browsers to use masking there are other
applications (like IPC protocols) that want to user websocket framing and proxy-traversing
characteristics without the overhead of masking. The websocket standard
also mentions that the requirement for mask verification on server side
might be dropped in future.

Modifications:

Added an optional parameter allowMaskMismatch for the websocket decoder
that allows a server to also accept unmasked frames (and clients to accept
masked frames).
Allowed to set this option through the websocket handshaker
constructors as well as the websocket client and server handlers.
The public API for existing components doesn't change, it will be
forwarded to functions which implicetly set masking as required in the
specification.
For websocket clients an additional parameter is added that allows to
disable the masking of frames that are sent by the client.

Result:

This update gives netty users the ability to create and use completely
unmasked websocket connections in addition to the normal masked channels
that the standard describes.

At the moment the whole HTTP header must be parsed at once which can lead to multiple parsing of the same bytes. We can do better here and allow to parse it in multiple steps.

Modifications:

 - Not parse headers multiple times
 - Simplify the code
 - Eliminate uncessary String[] creations
 - Use readSlice(...).retain() when possible.

Result:

Performance improvements as shown in the included benchmark below.

0666924e8c Don't close the connection whenever Expect: 100-continue is missing.
Motivation:

The 4.1.0-Beta3 implementation of HttpObjectAggregator.handleOversizedMessage closes the
connection if the client sent oversized chunked data with no Expect:
100-continue header. This causes a broken pipe or "connection reset by
peer" error in some clients (tested on Firefox 31 OS X 10.9.5,
async-http-client 1.8.14).

This part of the HTTP 1.1 spec (below) seems to say that in this scenario the connection
should not be closed (unless the intention is to be very strict about
how data should be sent).

http://www.w3.org/Protocols/rfc2616/rfc2616-sec8.html

"If an origin server receives a request that does not include an
Expect request-header field with the "100-continue" expectation,
the request includes a request body, and the server responds
with a final status code before reading the entire request body
from the transport connection, then the server SHOULD NOT close
the transport connection until it has read the entire request,
or until the client closes the connection. Otherwise, the client
might not reliably receive the response message. However, this
requirement is not be construed as preventing a server from
defending itself against denial-of-service attacks, or from
badly broken client implementations."

Modifications:

Change HttpObjectAggregator.handleOversizedMessage to close the
connection only if keep-alive is off and Expect: 100-continue is
missing. Update test to reflect the change.

Result:

Broken pipe and connection reset errors on the client are avoided when
oversized data is sent.

789e323b79 Handle an empty ByteBuf specially in HttpObjectEncoder
Related: #2983

Motivation:

It is a well known idiom to write an empty buffer and add a listener to
its future to close a channel when the last byte has been written out:

  ChannelFuture f = channel.writeAndFlush(Unpooled.EMPTY_BUFFER);
  f.addListener(ChannelFutureListener.CLOSE);

When HttpObjectEncoder is in the pipeline, this still works, but it
silently raises an IllegalStateException, because HttpObjectEncoder does
not allow writing a ByteBuf when it is expecting an HttpMessage.

Modifications:

- Handle an empty ByteBuf specially in HttpObjectEncoder, so that
  writing an empty buffer does not fail even if the pipeline contains an
  HttpObjectEncoder
- Add a test

Result:

An exception is not triggered anymore by HttpObjectEncoder, when a user
attempts to write an empty buffer.

67c68ef8ba CorsHandler should release HttpRequest after processing preflight/error.
Motivation:
Currently, when the CorsHandler processes a preflight request, or
respondes with an 403 Forbidden using the short-curcuit option, the
HttpRequest is not released which leads to a buffer leak.

Modifications:
Releasing the HttpRequest when done processing a preflight request or
responding with an 403.

Result:
Using the CorsHandler will not cause buffer leaks.

eb415fded6 V4.1 Fix "=" character in HttpPostRequestDecoder
Motivation
Issue #3004 shows that "=" character was not supported as it should in
the HttpPostRequestDecoder in form-data boundary.

Modifications:
Add 2 methods in StringUtil
- split with maxPart argument: String split with max parts only (to prevent multiple '='
to be source of extra split while not needed)
- substringAfter: String part after delimiter (since first part is not
needed)
Use those methods in HttpPostRequestDecoder.
Change and the HttpPostRequestDecoderTest to check using a boundary
beginning with "=".

Results:
The fix implies more stability and fix the issue.

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.

4a45d23129 Add the encoder/decoder getter methods to HttpClientCodec
Motivation:

There's no way for a user to get the encoder and the decoder of an
HttpClientCodec.  The lack of such getter methods makes it impossible to
remove the codec handlers from the pipeline correctly.

For example, a user could add more than one HttpClientCodec to the
pipeline, and then the user cannot easily decide which encoder and
decoder to remove.

Modifications:

- Add encoder() and decoder() method to HttpClientCodec which returns
  HttpRequestEncoder and HttpResponseDecoder respectively
- Also made the same changes to HttpServerCodec

Result:

A user can distinguish the handlers added by multiple HttpClientCodecs
easily.

01e3bcf30c Add verification for websocket subprotocol on the client side.
Motivation:

Websocket clients can request to speak a specific subprotocol. The list of
subprotocols the client understands are sent to the server. The server
should select one of the protocols an reply this with the websocket
handshake response. The added code verifies that the reponded subprotocol
is valid.

Modifications:

Added verification of the subprotocol received from the server against the
subprotocol(s) that the user requests. If the user requests a subprotocol
but the server responds none or a non-requested subprotocol this is an
error and the handshake fails through an exception. If the user requests
no subprotocol but the server responds one this is also marked as an
error.

Addiontionally a getter for the WebSocketClientHandshaker in the
WebSocketClientProtocolHandler is added to enable the user of a
WebSocketClientProtocolHandler to extract the used negotiated subprotocol.

Result:

The subprotocol field which is received from a websocket server is now
properly verified on client side and clients and websocket connection
attempts will now only succeed if both parties can negotiate on a
subprotocol.
If the client sends a list of multiple possible subprotocols it can
extract the negotiated subprotocol through the added handshaker getter (WebSocketClientProtocolHandler.handshaker().actualSubprotocol()).

80ae2c9180 Add a test for handover from HTTP to Websocket
Motivation:
I was not fully reassured that whether everything works correctly when a websocket client receives the websocket handshake HTTP response and a websocket frame in a single ByteBuf (which can happen when the server sends a response directly or shortly after the connect). In this case some parts of the ByteBuf must be processed by HTTP decoder and the remaining by the websocket decoder.

Modification:
Adding a test that verifies that in this scenaria the handshake and the message are correctly interpreted and delivered by Netty.

Result:
One more test for Netty.
The test succeeds - No problems

43681b5608 Avoid vectored writes for small websocket messages
Motivation:
The WebSocket08FrameEncoder contains an optimization path for small messages which copies the message content into the header buffer to avoid vectored writes. However this path is in the current implementation never taken because the target buffer is preallocated only for exactly the size of the header.

Modification:
For messages below a certain treshold allocate the buffer so that the message can be directly copied. Thereby the optimized path is taken.

Result:
A speedup of about 25% for 100byte messages. Declines with bigger message sizes. I have currently set the treshold to 1kB which is a point where I could still see a few percent speedup, but we should also avoid burning too many CPU cycles.

4eb1529d2c Improve WebSocket performance
Motivation:

Websocket performance is to a large account determined through the masking
and unmasking of frames. The current behavior of this in Netty can be
improved.

Modifications:

Perform the XOR operation not bytewise but in int blocks as long as
possible. This reduces the number of necessary operations by 4. Also don't
read the writerIndex in each iteration.
Added a unit test for websocket decoding and encoding for verifiation.

Result:

A large performance gain (up to 50%) in websocket throughput.

ffda229cf4 Send a websocket close frame with status code when receiving invalid frames
Motivation:

According to the websocket specification peers may send a close frame when
they detect a protocol violation (with status code 1002). The current
implementation simply closes the connection. This update should add this
functionality. The functionality is optional - but it might help other
implementations with debugging when they receive such a frame.

Modification:

When a protocol violation in the decoder is detected and a close was not
already initiated by the remote peer a close frame is
sent.

Result:

Remotes which will send an invalid frame will now get a close frame that
indicates the protocol violation instead of only seeing a closed
connection.

003f97168c HTTP Content Decoder Cleanup Bug
Motiviation:
The HTTP content decoder's cleanup method is not cleaning up the decoder correctly.

ca29be5e77 Allow ChunkedInput to provide the progress of its transfer
Related issue: #2741 and #2151

Motivation:

There is no way for ChunkedWriteHandler to know the progress of the
transfer of a ChannelInput. Therefore, ChannelProgressiveFutureListener
cannot get exact information about the progress of the transfer.

If you add a few methods that optionally provides the transfer progress
to ChannelInput, it becomes possible for ChunkedWriteHandler to notify
ChannelProgressiveFutureListeners.

If the input has no definite length, we can still use the progress so
far, and consider the length of the input as 'undefined'.

Modifications:

- Add ChunkedInput.progress() and ChunkedInput.length()
- Modify ChunkedWriteHandler to use progress() and length() to notify
  the transfer progress

Result:

ChunkedWriteHandler now notifies ChannelProgressiveFutureListener.

af26826348 SPDY: fix SpdySessionHandler::updateSendWindowSize
In Netty 3, downstream writes of SPDY data frames and upstream reads of
SPDY window udpate frames occur on different threads.

When receiving a window update frame, we synchronize on a java object
(SpdySessionHandler::flowControlLock) while sending any pending writes
that are now able to complete.

When writing a data frame, we check the send window size to see if we
are allowed to write it to the socket, or if we have to enqueue it as a
pending write. To prevent races with the window update frame, this is
also synchronized on the same SpdySessionHandler::flowControlLock.

In Netty 4, upstream and downstream operations on any given channel now
occur on the same thread. Since java locks are re-entrant, this now
allows downstream writes to occur while processing window update frames.

In particular, when we receive a window update frame that unblocks a
pending write, this write completes which triggers an event notification
on the response, which in turn triggers a write of a data frame. Since
this is on the same thread it re-enters the lock and modifies the send
window. When the write completes, we continue processing pending writes
without knowledge that the window size has been decremented.

8e1007d693 Fix a bug where SpdySession.getActiveStreams() returns incorrect set
Related issue: #2743

Motivation:

When there are more than one stream with the same priority, the set
returned by SpdySession.getActiveStream() will not include all of them,
because it uses TreeSet and only compares the priority of streams. If
two different streams have the same priority, one of them will be
discarded by TreeSet.

Modification:

- Rename getActiveStreams() to activeStreams()
- Replace PriorityComparator with StreamComparator

Result:

Two different streams with the same priority are compared correctly.

b83df4c6b3 Fix NPE problems
Motivation:

Now Netty has a few problems with null values.

Modifications:

- Check HAProxyProxiedProtocol in HAProxyMessage constructor and throw NPE if it is null.
If HAProxyProxiedProtocol is null we will set AddressFamily as null. So we will get NPE inside checkAddress(String, AddressFamily) and it won't be easy to understand why addrFamily is null.
- Check File in DiskFileUpload.toString().
If File is null we will get NPE when calling toString() method.
- Check Result<String> in MqttDecoder.decodeConnectionPayload(...).
If !mqttConnectVariableHeader.isWillFlag() || !mqttConnectVariableHeader.hasUserName() || !mqttConnectVariableHeader.hasPassword() we will get NPE when we will try to create new instance of MqttConnectPayload.
- Check Unsafe before calling unsafe.getClass() in PlatformDependent0 static block.
- Removed unnecessary null check in WebSocket08FrameEncoder.encode(...).
Because msg.content() can not return null.
- Removed unnecessary null check in DefaultStompFrame(StompCommand) constructor.
Because we have this check in the super class.
- Removed unnecessary null checks in ConcurrentHashMapV8.removeTreeNode(TreeNode<K,V>).
- Removed unnecessary null check in OioDatagramChannel.doReadMessages(List<Object>).
Because tmpPacket.getSocketAddress() always returns new SocketAddress instance.
- Removed unnecessary null check in OioServerSocketChannel.doReadMessages(List<Object>).
Because socket.accept() always returns new Socket instance.
- Pass Unpooled.buffer(0) instead of null inside CloseWebSocketFrame(boolean, int) constructor.
If we will pass null we will get NPE in super class constructor.
- Added throw new IllegalStateException in GlobalEventExecutor.awaitInactivity(long, TimeUnit) if it will be called before GlobalEventExecutor.execute(Runnable).
Because now we will get NPE. IllegalStateException will be better in this case.
- Fixed null check in OpenSslServerContext.setTicketKeys(byte[]).
Now we throw new NPE if byte[] is not null.

Result:

Added new null checks when it is necessary, removed unnecessary null checks and fixed some NPE problems.

ad1389be9d Small performance improvements
Modifications:

- Added a static modifier for CompositeByteBuf.Component.
This class is an inner class, but does not use its embedded reference to the object which created it. This reference makes the instances of the class larger, and may keep the reference to the creator object alive longer than necessary.
- Removed unnecessary boxing/unboxing operations in HttpResponseDecoder, RtspResponseDecoder, PerMessageDeflateClientExtensionHandshaker and PerMessageDeflateServerExtensionHandshaker
A boxed primitive is created from a String, just to extract the unboxed primitive value.
- Removed unnecessary 3 times calculations in DiskAttribute.addContent(...).
- Removed unnecessary checks if file exists before call mkdirs() in NativeLibraryLoader and PlatformDependent.
Because the method mkdirs() has this check inside.
- Removed unnecessary `instanceof AsciiString` check in StompSubframeAggregator.contentLength(StompHeadersSubframe) and StompSubframeDecoder.getContentLength(StompHeaders, long).
Because StompHeaders.get(CharSequence) always returns java.lang.String.

909d1f2c0f Reuse previous created HttpHeaders by HttpObjectAggregator
Motivation:

HttpObjectAggregator currently creates a new FullHttpResponse / FullHttpRequest for each message it needs to aggregate. While doing so it also creates 2 DefaultHttpHeader instances (one for the headers and one for the trailing headers). This is bad for two reasons:
  - More objects are created then needed and also populate the headers is not for free
  - Headers may get validated even if the validation was disabled in the decoder

Modification:

- Wrap the previous created HttpResponse / HttpRequest and so reuse the original HttpHeaders
- Reuse the previous created trailing HttpHeader.
- Fix a bug where the trailing HttpHeader was incorrectly mixed in the headers.

Result:

- Less GC
- Faster HttpObjectAggregator implementation

085a61a310 Refactor FastThreadLocal to simplify TLV management
Motivation:

When Netty runs in a managed environment such as web application server,
Netty needs to provide an explicit way to remove the thread-local
variables it created to prevent class loader leaks.

FastThreadLocal uses different execution paths for storing a
thread-local variable depending on the type of the current thread.
It increases the complexity of thread-local removal.

Modifications:

- Moved FastThreadLocal and FastThreadLocalThread out of the internal
  package so that a user can use it.
- FastThreadLocal now keeps track of all thread local variables it has
  initialized, and calling FastThreadLocal.removeAll() will remove all
  thread-local variables of the caller thread.
- Added FastThreadLocal.size() for diagnostics and tests
- Introduce InternalThreadLocalMap which is a mixture of hard-wired
  thread local variable fields and extensible indexed variables
- FastThreadLocal now uses InternalThreadLocalMap to implement a
  thread-local variable.
- Added ThreadDeathWatcher.unwatch() so that PooledByteBufAllocator
  tells it to stop watching when its thread-local cache has been freed
  by FastThreadLocal.removeAll().
- Added FastThreadLocalTest to ensure that removeAll() works
- Added microbenchmark for FastThreadLocal and JDK ThreadLocal
- Upgraded to JMH 0.9

Result:

- A user can remove all thread-local variables Netty created, as long as
  he or she did not exit from the current thread. (Note that there's no
  way to remove a thread-local variable from outside of the thread.)
- FastThreadLocal exposes more useful operations such as isSet() because
  we always implement a thread local variable via InternalThreadLocalMap
  instead of falling back to JDK ThreadLocal.
- FastThreadLocalBenchmark shows that this change improves the
  performance of FastThreadLocal even more.

Motivation:

We have quite a bit of code duplication between HTTP/1, HTTP/2, SPDY,

  - 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
- 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

Modification:
Add a "FastThreadLocal" which uses an EnumMap and a predefined fixed set of possible thread locals (all of the static instances created by netty) that is around 10-20% faster than standard ThreadLocal in my benchmarks (and can be seen having an effect in the direct PooledByteBufAllocator benchmark that uses the DEFAULT ByteBufAllocator which uses this FastThreadLocal, as opposed to normal instantiations that do not, and in the new RecyclableArrayList benchmark);

Result:
Improved performance

8074b5c6ee [#2542] HTTP post request decoder does not support quoted boundaries
Motivation:
According to RFC2616 section 19, boundary string could be quoted, but
currently the PostRequestDecoder does not support it while it should.

Modifications:
Once the boundary is found, one check is made to verify if the boundary
is "quoted", and if so, it is "unqoted".

Note: in following usage of this boundary (as delimiter), quote seems no
more allowed according to the same RFC, so the reason that only the
boundary definition is corrected.

Result:
Now the boundary could be whatever quoted or not. A Junit test case
checks it.

f402350d76 [#2544] Correctly parse Multipart-mixed POST HTTP request in case of entity ends with odd number of 0x0D
Motivation:
When an attribute is ending with an odd number of CR (0x0D), the decoder
add an extra CR in the decoded attribute and should not.

Modifications:
Each time a CR is detected, the next byte was tested to be LF or not. If
not, in a number of places, the CR byte was lost while it should not be.
When a CR is detected, if the next byte is not LF, the CR byte should be
saved as the position point to the next byte (not LF). When a CR is
detected, if there is not yet other available bytes, the position is
reset to the position of CR (since a LF could follow).

A new Junit test case is added, using DECODER and variable number of CR
in the final attribute (testMultipartCodecWithCRasEndOfAttribute).

Result:
The attribute is now correctly decoded with the right number of CR
ending bytes.

8b0a0f9a8f 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

1a22186645 Adding short-curcuit option for CORS
Motivation:
CORS request are currently processed, and potentially failed, after the
target ChannelHandler(s) have been invoked. This might not be desired, for
example a HTTP PUT or POST might have been performed.

Modifications:
Added a shortCurcuit option to CorsConfig which when set will
cause a validation of the HTTP request's 'Origin' header and verify that
it is valid according to the configuration. If found invalid an 403
"Forbidden" response will be returned and not further processing will
take place.

This is indeed no help for non browser request, like using curl, which
can set the 'Origin' header.

Result:
Users can now configure if the 'Origin' header should be validated
upfront and have the request rejected before any further processing
takes place.

d713f015da Made websocket maxFramePayloadSize configurable from WebSocketServerProtocolHandler.
Motivation:

Currently there's no way to configure maxFramePayloadSize from
WebSocketServerProtocolHandler, which is the most used entry point of
WebSocket server.

Modifications:

Added another constructor for maxFramePayloadSize.

Result:

We can configure max frame size for websocket packet in
WebSocketServerProtocolHandler. It will also keep backward compatibility
with default max size: 65536. (65536 is hard-coded max size in previous
version of Netty)

93fab1d5a3 Remove ContinuationWebSocketFrame.aggregatedText()
Motivation:
Before we aggregated the full text in the WebSocket08FrameDecoder just to fill in the ContinuationWebSocketFrame.aggregatedText(). The problem was that there was no upper-limit and so it would be possible to see an OOME if the remote peer sends a TextWebSocketFrame + a never ending stream of ContinuationWebSocketFrames. Furthermore the aggregation does not really belong in the WebSocket08FrameDecoder, as we provide an extra ChannelHandler for this anyway (WebSocketFrameAggregator).

Modification:
Remove the ContinuationWebSocketFrame.aggregatedText() method and corresponding constructor. Also refactored WebSocket08FrameDecoder a bit to me more efficient which is now possible as we not need to aggregate here.

Result:
No more risk of OOME because of frames.

2f082cf9a2 Adding support for echoing the request origin for CORS.
Motivation:
When CORS has been configured to allow "*" origin, and at the same time
is allowing credentials/cookies, this causes an error from the browser
because when the response 'Access-Control-Allow-Credentials' header
is true, the 'Access-Control-Allow-Origin' must be an actual origin.

Modifications:
Changed CorsHandler setOrigin method to check for the combination of "*"
origin and allowCredentials, and if the check matches echo the CORS
request's 'Origin' value.

Result:
This addition enables the echoing of the request 'Origin' value as the
'Access-Control-Allow-Origin' value when the server has been configured
to allow any origin in combination with allowCredentials.

This allows client requests to succeed when expecting the server to
be able to handle "*" origin and at the same time be able to send cookies
by setting 'xhr.withCredentials=true'. A concrete example of this is
the SockJS protocol which expects behaviour.

7808b9926d 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.

4fc9afa102 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.

110878fe2c Fixing CorsConfigTest failure under Java 8.
Motivation:
When running the build with Java 8 the following error occurred:

java: reference to preflightResponseHeader is ambiguous
  both method
  <T>preflightResponseHeader(java.lang.CharSequence,java.lang.Iterable<T>)
  in io.netty.handler.codec.http.cors.CorsConfig.Builder and method
  <T>preflightResponseHeader(java.lang.String,java.util.concurrent.Callable<T>)
  in io.netty.handler.codec.http.cors.CorsConfig.Builder match

The offending class was CorsConfigTest and its shouldThrowIfValueIsNull
which contained the following line:
withOrigin("*").preflightResponseHeader("HeaderName", null).build();

Modifications:
Updated the offending method with to supply a type, and object array, to
avoid the error.

Result:

74f418bace Adding support for specifying preflight response headers.
Motivation:

An intermediary like a load balancer might require that a Cross Origin
Resource Sharing (CORS) preflight request have certain headers set.
As a concrete example the Elastic Load Balancer (ELB) requires the
'Date' and 'Content-Length' header to be set or it will fail with a 502
error code.

This works is an enhancement of https://github.com/netty/netty/pull/2290

Modifications:

CorsConfig has been extended to make additional HTTP response headers
configurable for preflight responses. Since some headers, like the
'Date' header need to be generated each time, m0wfo suggested using a
Callable.

Result:

By default, the 'Date' and 'Content-Lenght' headers will be sent in a
preflight response. This can be overriden and users can specify
any headers that might be required by different intermediaries.

397f81f253 [#2305] Fix issue related to decoding post request raized an exception due to a split of information by chunk not correctly taken into account by the decoder
Motivation:

If the last item analyzed in a previous received HttpChunk/HttpContent was a part of an attribute's name, the read index was not set to the new right place and therefore raizing an exception in some case (since the "new" name analyzed is empty, which is not allowed so the exception).

What appears there is that the read index should be reset to the last valid position encountered whatever the case. Currently it was set when only when there is an attribute not already finished (name is ok, but content is possibly not).

Therefore the issue is that elements could be rescanned multiple times (including completed elements) and moreover some bad decoding can occur such as when in a middle of an attribute's name.

Modifications:

To fix this issue, since "firstpos" contains the last "valid" read index of the decoding (when finding a '&', '=', 'CR/LF'), we should add the setting of the read index for the following cases:

'lastchunk' encountered, therefore finishing the current buffer
any other cases than current attribute is not finished (name not found yet in particular)
So adding for this 2 cases:

undecodedChunk.readerIndex(firstpos);

Result:

Now the decoding is done once, content is added from chunk/content to chunk/content, name is decoded correctly even if in the middle of 2 chunks/contents.
A Junit test code was added: testChunkCorrect that should not raized any exception.

24fc1b9b37 Fix a bug where HttpObjectDecoder generates two LastHttpContent consecutively
Motivation:
When an HttpResponseDecoder decodes an invalid chunk, a LastHttpContent instance is produced and the decoder enters the 'BAD_MESSAGE' state, which is not supposed to produce a message any further.  However, because HttpObjectDecoder.invalidChunk() did not clear this.message out to null, decodeLast() will produce another LastHttpContent message on a certain situation.

Modification:
Do not forget to null out HttpObjectDecoder.message in invalidChunk(), and add a test case for it.

Result:
No more consecutive LastHttpContent messages produced by HttpObjectDecoder.

2c4aff13c7 Add an operation that resets the state of HttpObjectDecoder
Motivation:

Currently, it is impossible to give a user the full control over what to do in response to the request with 'Expect: 100-continue' header.  Currently, a user have to do one of the following:

- Accept the request and respond with 100 Continue, or
- Send the reject response and close the connection.

.. which means it is impossible to send the reject response and keep the connection alive so that the client sends additional requests.

Modification:

Added a public method called 'reset()' to HttpObjectDecoder so that a user can reset the state of the decoder easily.  Once called, the decoder will assume the next input will be the beginning of a new request.

HttpObjectAggregator now calls `reset()`right after calling 'handleOversizedMessage()' so that the decoder can continue to decode the subsequent request even after the request with 'Expect: 100-continue' header is rejected.

3ce35c710a Improves SelectedProtocol enum to avoid boilerplate on subclasses
NPN server providers return a String version of the negotiated protocol
and the getProtocolByName method allows to easily get an instance of
the SelectedProtocol enum and avoid the need for a switch statement in
each subclass to match the String against the enum value.

0f76b3c357 Remove unnecessary code from HttpObjectDecoder and re-enable all HTTP tests
- Since Netty 4, HTTP decoder does not generate a full message at all.  Therefore, there's no need to keep separate states for the content smaller than maxChunkSize.
- maxChunkSize must be greater than 0. Setting it to 0 should not disable chunked encoding. We have a dedicated flag for that.
- Uncommented the tests that were commented out for an unknown reason, with some fixes.
- Added more tests for HTTP decoder.
- Removed the Ignore annotation on some tests.

407f0a36f5 Simplify bundle generation / Add io.netty.versions.properties to all JARs
- 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
