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

ef13d19b8b [#5202] Correctly throw ErrorDataDecoderException when invalid encoded form parameters are present.
Motivation:

At the moment we let the IllegalArgumentException escape when parsing form parameters. This is not expected.

Modifications:

Correctly catch IllegalArgumentException and rethrow as ErrorDataDecoderException.

Result:

Throw correct exception.

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.

5b59250657 TreeMap extra get operation removed.
Motivation:
Checking if a key exists on a TreeMap has a Big O of "log 2 N",
doing it twice is not cheap.

Modifications:
Get the key instead which has the same cost and check if it is null.

Result:
Faster code due to one expensive operation removed.

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

We missed to reset the decoder when asked for it in HttpObjectDecoder and so sometimes could produce more then one LastHttpContent in a sequence during channelInactive.

This did show up as AssertionError:

22:22:35.499 [nioEventLoopGroup-3-1] WARN  i.n.channel.DefaultChannelPipeline - An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.

24254b159f Propagate h2c upgrade success event to the next handler before removing source codec
Motivation:

When upgrading h2c, I found that sometimes both of http2 settings frame and http response message was arrived before receiving upgrade success event. It was because ByteToMessageDecoder propagated its internally buffered message to the next handler when removing itself from pipeline.(refer to ByteToMessageDecoder#handlerRemoved)
I think it's better to propagate upgrade success event when handling 101 switching protocol response.

Modifications:

Upgrade success event will be propagated before removing source codec.

Result:

It guarantees that upgrade success event will be arrived first at the next handler.

881ff3cd98 Drop broken DefaultCookie name validation, close #4999
Motivation:

DefaultCookie constructor performs a name validation that doesn’t match
RFC6265. Moreover, such validation is already performed in strict
encoders and decoders.

Modifications:

Drop DefaultCookie name validation, rely on encoders and decoders.

Result:

no more duplicate broken validation

8ec594c6eb Change HttpServerUpgradeHandler.UpgradeCodec to allow aborting upgrade
Motivation:

HttpServerUpgradeHandler.UpgradeCodec.prepareUpgradeResponse should allow to abort the upgrade and so just continue with using HTTP. Beside this we should only pass in the response HttpHeaders as this is inline with the docs.

Modifications:

- UpgradeCodec.prepareUpgradeResponse now allows to return a boolean and so allows to specifiy if the upgrade should take place.
- Change the param from FullHttpResponse to HttpHeaders to be inline with the javadocs.

Result:

More flexible and correct handling of upgrades.

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.

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.

- 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:

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.

Motivation:

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

Modification:

- Use this method to detect handshake

Result:

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

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.

0b16c3c513 Add a possibility to create HttpMessage instances with pre-existing Headers
Motivation:

Allow passing HttpHeaders instance to DefaultHttpMessage
in order to avoid eager creation of Headers to
allow users reuse their Headers instance.

Modifications:

Added a constructor with HttpHeaders to DefaultHttpMessage,
Modified DefaultHttpResponse and DefaultHttpRequest
to receive HttpHeaders instances.
Modified DefaultFullHttpReqest and DefaultFullHttpResponse
to receive HttpHeaders, and updated `duplicate` and
`copy` to use new constructors.

Result:

Users can now pass HttpHeaders instance when
constructing Http Requests and Responses.

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.

2a65ae256e [#4331] Helper methods to get charset from Content-Type header of HttpMessage
Motivation:

HttpHeaders already has specific methods for such popular and simple headers like "Host", but if I need to convert POST raw body to string I need to parse complex ContentType header in my code.

Modifications:

Add getCharset and getCharsetAsString methods to parse charset from Content-Length header.

Result:

Easy to use utility method.

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.

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

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

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.
