Motivation:
The maven surefire plugin will trim stacktraces by default which makes these kind of use-less when trying to understand why an test failed because one was thrown.
Modifications:
Configure the plugin to not trim the stacktrace.
Result:
Easier to debug test-failures.
Motivation:
This is a followup for #7860. In the fix for #7860 we only partly fixed the problem as Http2UnknownFrame did not correctly extend HttpStreamFrame and so only worked when using the Http2FrameCodec. We need to have it extend HttpStreamFrame as otherwise Http2MultiplexCodec will reject to handle it correctly.
Modifications:
- Let Http2UnknownFrame extend HttpStreamFrame
- Add unit tests for writing and reading Http2UnkownFrame instances when the Http2MultiplexCodec is used.
Result:
Fixes https://github.com/netty/netty/issues/7969.
motivation: setup for testing across different permutations of linux and java versions
changes:
* refactor docker file to allow dynamic versions of centos and java
* add docker compose driver files for centos 6, 7 and java 1.8, 1.9, 1.10, 1.11
* update instructions
Motivation:
The websockets abstract test suite does not run against the 08
implementation in the 08 version of the test suite.
Modifications:
Update the WebSocketClientHandshaker08Test to instantiate a new
WebSocketClientHandshaker08 rather than an 07 handshaker.
Result:
The WebSocketClientHandshaker08Test now tests the 08 implementation.
Motivation:
On J9 / OpenJ9 netty initializes this value with 64M, even the direct accessible memory is actually unbounded.
Modifications:
Skip usage of VM.maxDirectMemory() on J9 / OpenJ9
Result:
More correct direct memory limit detection. Fixes#7654.
Motivation:
A long time ago we deprecated AUTO_CLOSE but it turned out this feature is still useful because if a write error is detected there still maybe data to read, and if we close the channel automatically we will lose data
Modifications:
- Remove `@Deprecated` tag for AUTO_CLOSE, setAutoClose(...) and isAutoClose(...)
- Fix javadocs on ChannelConfig to correctly tell the default value of AUTO_CLOSE.
Result:
Less warnings.
* Read until all data is consumed when EOF is detected even if readPending is false and auto-read is disabled.
Motivation:
We should better always notify the user of EOF even if the user did not request any data as otherwise we may never be notified when the remote peer closes the connection. This should be ok as the amount of extra data we may read and so fire through the pipeline is limited by SO_RECVBUF.
Modifications:
- Always drain the socket when EOF is detected.
- Add testcase
Result:
No risk for the user to be not notified of EOF.
Motivation:
Currently, on recipt of a PongWebSocketFrame, the
WebSocketProtocolHandler will drop the frame, rather than passing it
along so it can be referenced by other handlers.
Modifications:
Add boolean field to WebSocketProtocolHandler to indicate whether Pong
frames should be dropped or propagated, defaulting to "true" to preserve
existing functionality.
Add new constructors to the client and server implementations of
WebSocketProtocolHandler that allow for overriding the behavior for the
handling of Pong frames.
Result:
PongWebSocketFrames are passed along the channel, if specified.
Motivation:
DefaultHttpResponse did not respect its status when compute the hashCode and check for equality.
Modifications:
Correctly implement hashCode and equals
Result:
Fixes https://github.com/netty/netty/issues/7964.
Motivation:
We need to ensure we only return from close() after all work is done as otherwise we may close the EventExecutor before we dispatched everything.
Modifications:
Correctly wait on operations to complete before return.
Result:
Fixes https://github.com/netty/netty/issues/7901.
Motivation:
When a sender sends too large of headers it should not unnecessarily
kill the connection, as killing the connection is a heavy-handed
solution while SETTINGS_MAX_HEADER_LIST_SIZE is advisory and may be
ignored.
The maxHeaderListSizeGoAway limit in HpackDecoder is unnecessary because
any headers causing the list to exceeding the max size can simply be
thrown away. In addition, DefaultHttp2FrameReader.HeadersBlockBuilder
limits the entire block to maxHeaderListSizeGoAway. Thus individual
literals are limited to maxHeaderListSizeGoAway.
(Technically, literals are limited to 1.6x maxHeaderListSizeGoAway,
since the canonical Huffman code has a maximum compression ratio of
.625. However, the "unnecessary" limit in HpackDecoder was also being
applied to compressed sizes.)
Modifications:
Remove maxHeaderListSizeGoAway checking in HpackDecoder and instead
eagerly throw away any headers causing the list to exceed
maxHeaderListSize.
Result:
Fewer large header cases will trigger connection-killing.
DefaultHttp2FrameReader.HeadersBlockBuilder will still kill the
connection when maxHeaderListSizeGoAway is exceeded, however.
Fixes#7887
Motivation:
When we build the key-material we should use the ByteBufAllocator used by the ReferenceCountedOpenSslEngine when possible.
Modifications:
Whenever we have access to the ReferenceCountedOpenSslEngine we use its allocator.
Result:
Use correct allocator
Motivation:
We currently have only interopt tests for Conscrypt, we should also have non-interopt tests.
Modifications:
Add ConscryptSslEngineTest
Result:
More tests
Motivation:
We added a workaround for Java 11 as it not produced a connect-reset when SO_LINGER with 0 was set and NIO was used. This was fixed in the latest ea release of Java 11:
- http://hg.openjdk.java.net/jdk/jdk/rev/ea54197f4fe4
- https://bugs.openjdk.java.net/browse/JDK-8203059
Modifications:
Revert workaround.
Result:
Test that Java 11 behave the same way as earlier Java versions again.
Motivation:
We did not guard against the case of calling malloc(0) when creating a ByteBuffer without a Cleaner. The problem is that malloc(0) can have different behaviour, it either return a null-pointer or a valid pointer that you can pass to free.
The real problem arise if Unsafe.allocateMemory(0) returns 0 and we use it as the memoryAddress of the ByteBuffer. The problem here is that native libraries test for 0 and handle it as a null-ptr. This is for example true in SSL.bioSetByteBuffer(...) which would throw a NPE when 0 is used as memoryAddress and so produced errors during SSL usage.
Modifications:
- Always allocate 1 byte as minimum (even if we ask for an empty buffer).
- Add unit test.
Result:
No more errors possible because of malloc(0).
Motivation:
We previously did not correctly take into account when we could not wrap (and so produce) the full SSL record with an alert when the SSLEngine was closed.
There are two problems here:
- If we call wrap(...) with an empty dst buffer after closeOutbound() was called we will not notify the user if we could not store the whole SSLRecord into the dst buffer and so we may produce incomplete SSLRecords
Modifications:
Add unit test which failed before.
Result:
Correctly handle the case when the dst buffer is not big enough and and alert needs to be produced.
Motivation:
https://github.com/netty/netty/pull/7943 had a bug which caused to not have the argument passed to the delegating method.
Modifications:
Add argument to release call.
Result:
Correctly delegate method.
Motivation:
Some of the tests failed when using BoringSSL as some protocol / cipher combinations are not supported and it uses a different alert when the cert is not valid yet.
Modification:
- Remove protocol / cipher combos that are not supported by BoringSSL
- Test for different alert when using BoringSSL
Result:
Not test failures when using BoringSSL.
Motivation:
https://github.com/netty/netty/pull/7941 proved that its easy to not correctly clear the error stack sometimes. We should do carefully test this.
Modifications:
Add a new SSLEngine wrapper that is used during tests, which verifies that the error stack is empty after each method call.
Result:
Better testing.
Motivation:
We sometimes did not correctly detect when a protocol is not enabled when using netty-tcnative as we did not take into account when the option flag is 0 (as for example in BoringSSL for SSLv2).
Modifications:
- Correctly take an option flag with 0 into account.
- Add unit tests.
Result:
Fixes https://github.com/netty/netty/issues/7935.
Motivation:
We missed to correctly clear the error stack in one case when using the ReferenceCountedOpenSslEngine. Because of this it was possible to pick up an error on an unrelated operation.
Modifications:
- Correctly clear the stack
- Add verification of empty error stack to tests.
Result:
Not possible to observe unrelated errors.
Motivation:
We did not correctly copy elements in some cases when add(index, element) was used.
Modifications:
- Correctly detect when copy is neede and when not.
- Add test case.
Result:
Fixes https://github.com/netty/netty/issues/7938.
Netty/Transport/Native/Epoll project can be build on aarch64 platform as well.
Motivation:
To provide the support for AARCH64 architecture
Modification:
Adjusted regex for enforce plugin to also allow AARCH64.
Result:
Be able to compile on AARCH64
Motivation:
Integer autoboxing in this class (and possibly also the varargs arrays)
showed non-negligible CPU and garbage contribution when profiling a gRPC
service. grpc-java currently hardcodes use of Http2FrameLogger, set at
DEBUG level.
Modifications:
Wrap offending log statements in conditional blocks.
Result:
Garbage won't be produced by Http2FrameLogger when set to a disabled
logging level.
Motivation:
When I read the source code, I found that the comment of PoolChunk is out of date, it may confuses readers with the description about memoryMap.
Modifications:
update the last passage of the comment of the PoolChunk class.
Result:
No change to any source code , just update comment.
Motivation:
Java 11 will be out soon, so we should be able to build (and run tests) netty.
Modifications:
- Add dependency that is needed till Java 11
- Adjust tests so these also pass on Java 11 (SocketChannelImpl.close() behavious a bit differently now).
Result:
Build also works (and tests pass) on Java 11.
Motivation:
cff87de44c updated jboss-marshalling to 2.0.5.Final but this broke the ability to run tests with Java 7.
Modifications:
Only use 2.0.5.Final if compiled against Java 10 (as before 1.4.x works fine).
Result:
Be able to run tests with Java 7 on the CI.
Motivation:
Java 10 is out so we should be able to build netty with it (and run the tests).
Modifications:
- Update Mockito and JBoss Marshalling to support Java 10
- Fix unit test to not depend on specific cipher which is not present in Java 10 anymore
Result:
Netty builds (and runs all tests) when using Java 10
Motivation:
Currently, the testing-osgi is set to skip if run with java>=9. That is not necessary when using a newer version of Felix.
Modification:
Update to Felix framework 5.6.10 (which has better jpms support), add some more --add-opens to not have WARN messages, and remove the skipOsgiTestsuite setting from the parent pom.
Result:
OSGi tests run and pass on java>=9.
Motivation:
At the moment if you do a resolveAll and at least one A / AAAA record is present we will not follow any CNAMEs that are also present. This is different to how the JDK behaves.
Modifications:
- Allows follow CNAMEs.
- Add unit test.
Result:
Fixes https://github.com/netty/netty/issues/7915.
Motivation:
We added some code to guard against thread.interrupt() in NioEventLoop but did not added a test.
Modifications:
Add testcase.
Result:
Verify that we correctly handle interrupt().
Motivation:
a598c3b69b added a upper limit for ttl but missed to also do the same for minTtl.
Modifications:
- Add upper limit for minTtl
- Add testcase.
Result:
No more IllegalArgumentException possible.
Motivation:
When a buffer is over-released, the current error message of `IllegalReferenceCountException` is `refCnt: XXX, increment: XXX`, which is confusing. The correct message should be `refCnt: XXX, decrement: XXX`.
Modifications:
Pass `-decrement` to create `IllegalReferenceCountException`.
Result:
The error message will be `refCnt: XXX, decrement: XXX` when a buffer is over-released.
Motivation:
Closed `FixedChannelPool` fails acquire and release operations with
`IllegalStateException`s. These exceptions had message
"FixedChannelPooled was closed". Here "FixedChannelPooled" looks like
a typo and should probably be "FixedChannelPool".
Modifications:
Changed exception message to "FixedChannelPool was closed".
Result:
A tiny bit cleaner exception message.
Motivation:
We had a bug-report that claimed the src buffer used by OpenSslEngine will be zero out.
Modifications:
Add testcase to ensure correct behaviour
Result:
Testcase for https://github.com/netty/netty/issues/7753
Motivation:
Sometimes it's useful to disable native transports / native ssl to debug a problem. We should allow to do so with a system property so people not need to adjust code for this.
Modifications:
Add system properties which allow to disable native transport and native ssl.
Result:
Easier to disable native code usage without code changes.
Motivation:
Due a bug we did never store more then one address per hostname in DefaultDnsCache.
Modifications:
- Correctly store multiple entries per hostname
- Add tests
Result:
DefaultDnsCache correctly stores more then one entry. Also fixes https://github.com/netty/netty/issues/7882 .
Motivation:
In b47fb81799 we limited the max supported delay to match what our internal implementat can support. Because of this it was possible that DefaultDnsCache produced an IllegalArgumentException when it tried to schedule a expiration > 3 years.
Modifications:
Limit the max supported TTL to 2 years which is safe for all our EventLoop implementations.
Result:
No more exceptions when adding records to the cache with a huge TTL.
Motivation:
ChannelReadHandler is used in tests added via f4d7e8de14. In the handler we verify the number of messages we receive per read() call but missed to sometimes reset the counter which resulted in exceptions.
Modifications:
Correctly reset read counter in all cases.
Result:
No more unexpected exceptions when running LocalChannel tests.
Motivation:
HTTP responses with status of 205 should not contain a payload. We should enforce this.
Modifications:
Correctly handle responses with status 205 and payload by set Content-Length: 0 header and stripping out the content.
Result:
Fixes https://github.com/netty/netty/issues/7888
Motivation:
Streams can be deregistered so we can't assume their existence in the stream map.
Modifications:
Add a null-check in case a stream has been deregistered.
Result:
Fixes#7898.
Motivation:
It should be possible to call setContent(Unpooled.EMPTY_BUFFER) multiple times just like its possible to do the same with a non empty buffer.
Modifications:
- Correctly reset underlying storage if called multiple times.
- Add tests
Result:
Fixes https://github.com/netty/netty/issues/6418
Motivation:
b818852cdb added support for IP_RECVORIGDSTADDR but did not include any #ifdef statements to ensure its usable at all (which is not the case on MacOS).
Modifications:
Add #ifdef statements to check for IP_RECVORIGDSTADDR.
Result:
Compilation works again on MacOS.
