Motivation:
Fix leaks reported during running SpdyFrameDecoderTest
Modifications:
Make sure the produced buffers of SpdyFrameDecoder and SpdyFrameDecoderTest are released
Result:
No more leak reports during run the tests.
Motivation:
Fix leaks reported during running SpdyFrameDecoderTest
Modifications:
Make sure the produced buffer of SpdyFrameDecoder is released
Result:
No more leak reports during run the tests.
Motivation:
Fix leaks reported during SPDY test.
Modifications:
Use ReferenceCountUtil.releaseLater(...) to make sure everything is released once the tests are done.
Result:
No more leak reports during run the tests.
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.
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.
[https://github.com/netty/netty/issues/2346]
Motivation:
Previously, we used URLDecoder.decode(...) to decode url-encoded data. This generates a lot of garbage and takes a considerable amount of time.
Modifications:
Replace URLDecoder.decode(...) with QueryStringDecoder.decodeComponent(...)
Result:
Less garbage to GC and faster decode processing.
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
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.
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.
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.
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
Result:
This commit completes the fix of #2211
Exposing the constant as a public static final field is usually not a
good idea because it gives less flexibility to us when we happen to
change our internal implementation.
- Related: #2163
- Add ResourceLeakHint to allow a user to provide a meaningful information about the leak when touching it
- DefaultChannelHandlerContext now implements ResourceLeakHint to tell where the message is going.
- Cleaner resource leak report by excluding noisy stack trace elements
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.
- 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.
* No need to calculate the hash of known header names multiple times
* Optimize header encoding
* Also optimize the encoding of known header values
* Optimize encoding of HTTP method, version and status
