Motivation:
We need to notify the promise after the codecs are removed to allow writing from the listener and ensure we not try to do any encoding anymore. If we not do we will end up with corrupt data.
Modifications:
Notify promise after codecs are removed.
Result:
Fixes [#6671].
Motivation:
We missed some stuff in 5728e0eb2c and so the build failed on java9
Modifications:
- Add extra cmdline args when needed
- skip the autobahntestsuite as jython not works with java9
- skip the osgi testsuite as the maven plugin not works with java9
Result:
Build finally passed on java9
Motivation:
We used various mocking frameworks. We should only use one...
Modifications:
Make usage of mocking framework consistent by only using Mockito.
Result:
Less dependencies and more consistent mocking usage.
Motivation:
Currently Netty does not wrap socket connect, bind, or accept
operations in doPrivileged blocks. Nor does it wrap cases where a dns
lookup might happen.
This prevents an application utilizing the SecurityManager from
isolating SocketPermissions to Netty.
Modifications:
I have introduced a class (SocketUtils) that wraps operations
requiring SocketPermissions in doPrivileged blocks.
Result:
A user of Netty can grant SocketPermissions explicitly to the Netty
jar, without granting it to the rest of their application.
Motivation:
The HttpProxyHandler is expected to be capable of issuing a valid CONNECT request for a tunneled connection to an IPv6 host.
Modifications:
- Correctly format the IPV6 address.
- Add unit tests
Result:
HttpProxyHandler works with IPV6 as well. Fixes [#6152].
Motivation:
When auto-read is disabled and no reads are issued by a user, ProxyHandler will stall the connection on the proxy handshake phase waiting for the first response from a server (that was never read).
Modifications:
Read if needed when very first handshake message is send by ProxyHandler.
Result:
Proxy handshake now succeeds no matter if auto-read disabled or enabled. Without the fix, the new test is failing on master.
Motivation:
The current implementation does not comply with RFC2817 on two points:
- The HTTP version required to support the CONNECT method is 1.1,
but the current implementation specifies 1.0.
- The HOST header should hold the name or address of the Target Host,
but the current implementation uses the proxy address instead.
Modifications:
- Specify HTTP version 1.1,
- The HOST header is now set using the Target Host's name (or address,
if it is resolved).
Result:
The CONNECT request is RFC2817-compliant.
Motivation:
JCTools supports both non-unsafe, unsafe versions of queues and JDK6 which allows us to shade the library in netty-common allowing it to stay "zero dependency".
Modifications:
- Remove copy paste JCTools code and shade the library (dependencies that are shaded should be removed from the <dependencies> section of the generated POM).
- Remove usage of OneTimeTask and remove it all together.
Result:
Less code to maintain and easier to update JCTools and less GC pressure as the queue implementation nt creates so much garbage
Motivation:
ChannelInboundHandler and ChannelOutboundHandler both can implement exceptionCaught(...) method and so we need to dispatch to both of them.
Modifications:
- Correctly first dispatch exceptionCaught to the ChannelInboundHandler but also make sure the next handler it will be dispatched to will be the ChannelOutboundHandler
- Add removeInboundHandler() and removeOutboundHandler() which allows to remove one of the combined handlers
- Let *Codec extends it and not ChannelHandlerAppender
- Remove ChannelHandlerAppender
Result:
Correctly handle events and also have same behavior as in 4.0
Motivation:
As discussed in #4529, NameResolver design shouldn't be resolving SocketAddresses (or String name + port) and return InetSocketAddresses. It should resolve String names and return InetAddresses.
This SocketAddress to InetSocketAddresses resolution is actually a different concern, used by Bootstrap.
Modifications:
Extract SocketAddress to InetSocketAddresses resolution concern to a new class hierarchy named AddressResolver.
These AddressResolvers delegate to NameResolvers.
Result:
Better separation of concerns.
Note that new AddressResolvers generate a bit more allocations because of the intermediate Promise and List<InetAddress>.
