4b4f4e619e Fix integer overflow in HttpObjectEncoder when handling chunked encoding and FileRegion > Integer.MAX_VALUE
Motivation:

Due to integer overflow bug, writes of FileRegions to http server pipeline (eg like one from HttpStaticFileServer example) with length greater than Integer.MAX_VALUE are ignored in 1/2 of cases (ie no data gets sent to client)

Modification:

Correctly handle chunk sized > Integer.MAX_VALUE

Result:

Be able to use FileRegion > Integer.MAX_VALUE when using chunked encoding.

681d460938 Introduce TextHeaders and AsciiString
Motivation:

We have quite a bit of code duplication between HTTP/1, HTTP/2, SPDY,
and STOMP codec, because they all have a notion of 'headers', which is a
multimap of string names and values.

Modifications:

- Add TextHeaders and its default implementation
- Add AsciiString to replace HttpHeaderEntity
  - 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
  hash code calculation

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.

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:
After this I was able to build with Java 7 and Java 8

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.

Added relevant unit tests / Minor clean-up

- 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.
