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.

0d71744d5b IllegalRefCountException in FullHttp[Request|Response].hashCode()
Motivation:
FullHttp[Request|Response].hashCode() uses a releasable object and in vulnerable to a IllegalRefCountException if that object has been released.

Modifications:
- Ensure the released object is not used.

Result:
No more IllegalRefCountException.

6e108cb96a Improve the performance of copying header sets when hashing and name validation are equivalent.
Motivation:
Headers and groups of headers are frequently copied and the current mechanism is slower than it needs to be.

Modifications:
Skip name validation and hash computation when they are not necessary.
Fix emergent bug in CombinedHttpHeaders identified with better testing
Fix memory leak in DefaultHttp2Headers when clearing
Added benchmarks

Result:
Faster header copying and some collateral bug fixes

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.

2a4276e1ff SpdyHttpHeaders are not lowercase
Motivation:
According to the SPDY spec https://www.chromium.org/spdy/spdy-protocol/spdy-protocol-draft3-1#TOC-3.2.1-Request header names must be lowercase. Our predefined SPDY extension headers are not lowercase.

Modifications
- SpdyHttpHeaders should define header names in lower case

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

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

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

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

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

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

Modifications:

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

Result:

Correctly send close frame.

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

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

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

7049d8debb Add validateHeaders and headersToLowerCase options for SPDY
Motivation:

Related to issue #4185.

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

Modifications:

Added flags for validation and conversion.

Result:

SpdyHeader validation and conversion can be disabled.

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

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

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

Modifications:

Convert the header name to lowercase before adding it to SpdyHeaders

Result:

SpdyHttpEncoder can now convert a valid HttpResponse into a valid SpdyFrame

b6a4f5de9d Refactor of HttpUtil and HttpHeaderUtil
Motivation:
There currently exists http.HttpUtil, http2.HttpUtil, and http.HttpHeaderUtil. Having 2 HttpUtil methods can be confusing and the utilty methods in the http package could be consolidated.

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

Result:
Consolidated utilities whose names don't overlap.

85c79dbbe4 HTTP to HTTP/2 tranlation errors
Motivation:
HttpUtil.toHttp2Headers is currently not translating HTTP request headers to HTTP/2 request headers correctly.  The path, scheme, and authority are tranlation process are not respecting the HTTP/2 RFC https://tools.ietf.org/html/rfc7540#section-8.1.2.3 and HTTP RFC https://tools.ietf.org/html/rfc7230#section-5.3.

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

50b9768928 [#4095] Correctly handle Upgrade responses with special handling of Hixie 76
Motivation:

Hixie 76 needs special handling compared to other connection upgrade responses. Our detection code of non websocket responses did actually always use the special handling that only should be used for Hixie 76 responses.

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

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

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

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

e796c99b23 Add unit tests for HTTP and SPDY headers
Motivation:

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

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

Modifications:

Added more unit tests

Result:

Protect against issue #4053 happening again.
