Motivation:
We can use the diamond operator these days.
Modification:
Use diamond operator whenever possible.
Result:
More modern code and less boiler-plate.
Motivation:
Most of the maven modules do not explicitly declare their
dependencies and rely on transitivity, which is not always correct.
Modifications:
For all maven modules, add all of their dependencies to pom.xml
Result:
All of the (essentially non-transitive) depepdencies of the modules are explicitly declared in pom.xml
Motivation:
ProxyHandlerTest package uses deprecated methods SslContext.newServerContext and
SslContext.newClientContext.
Modifications:
SslContextBuilder is used to build server and client SslContext.
Result:
Less deprecated method in the code.
Motivation:
`ProxyHandlerTest` relies on random values to run tests: first to
shuffle collection of test items and lately to set configuration
flag for `AUTO_READ`. While the purpose of randomization is clear,
it's still impossible to reproduce the same sequence of test cases
when something went wrong. For `AUTO_READ` it's even impossible
to tell what flag was set when the particular test failed.
Modifications:
* Test runner now log seed values that was used for shuffling,
so you can take one and put in your tests to "freeze" them
while debugging (pretty common approach with randomized tests)
* `SuccessItemTest` is split into 2 different use cases:
for AUTO_READ flag set to "on" and "off"
Result:
You can reproduce specific tests results now.
Motivation:
HttpProxyHandler uses `NetUtil#toSocketAddressString` to compute
CONNECT url and Host header.
The url is correct when the address is unresolved, as
`NetUtil#toSocketAddressString` will then use
`getHoststring`/`getHostname`. If the address is already resolved, the
url will be based on the IP instead of the hostname.
There’s an additional minor issue with the Host header: default port
443 should be omitted.
Modifications:
* Introduce NetUtil#getHostname
* Introduce HttpUtil#formatHostnameForHttp to format an
InetSocketAddress to
HTTP format
* Change url computation to favor hostname instead of IP
* Introduce HttpProxyHandler ignoreDefaultPortsInConnectHostHeader
parameter to ignore 80 and 443 ports in Host header
Result:
HttpProxyHandler performs properly when connecting to a resolved address
Automatic-Module-Name entry provides a stable JDK9 module name, when Netty is used in a modular JDK9 applications. More info: http://blog.joda.org/2017/05/java-se-9-jpms-automatic-modules.html
When Netty migrates to JDK9 in the future, the entry can be replaced by actual module-info descriptor.
Modification:
The POM-s are configured to put the correct module names to the manifest.
Result:
Fixes#7218.
Motivation:
In some environments, the HTTP CONNECT handshake requires special headers to work.
Modification:
Update HttpProxyHandler to accept a HttpHeaders argument.
Result:
The header is passed along in the HTTP CONNECT request, and the proxy request can be successfully completed.
