Motivation:
We should keep the scope of the synchronized block as small as possible.
Modifications:
Reduce scope by copy to an array first before iterate through it
Result:
Smaller scope of synchronized
Motivation:
When an `AddressResolverGroup` closes, it can leave unwanted listeners attached to its `EventExecutor`'s termination future.
Modifications:
- Keep track of listeners attached to termination futures
- Clear listeners if the `AddressResolverGroup` closes before its associated executor(s)
Result:
Unwanted listeners no longer remain in memory after an `AddressResolverGroup` closes before its associated executor(s).
Motivation:
The resolver API and implementations should be considered stable by now so we should not mark these with @UnstableApi
Modifications:
Remove @UnstableApi annotation from API and implementation of resolver
Result:
Make it explicit that the API is considered stable
Motivation:
RoundRobinDnsAddressResolverGroup ultimately opens UDP
ports for DNS resolution. Callers likely expect that
RoundRobinDnsAddressResolverGroup#close() will close those
ports, but that is not currently true (see #9212).
Modifications:
Overrode RoundRobinInetAddressResolver#close() to close
the delegate name resolver, which in turn closes any UDP
ports used for name resolution.
Result:
RoundRobinDnsAddressResolverGroup#close() closes UDP ports
as expected. This fixes#9212.
Motivation:
In windows if the project is in a path that contains whitespace,
resources cannot be accessed and tests fail.
Modifications:
Adds ResourcesUtil.java in netty-common. Tests use ResourcesUtil.java to access a resource.
Result:
Being able to build netty in a path containing whitespace
Motivation:
We should support to parse and read a hosts file which is stored in a different encoding then the system default. Beside this when we are on windows we should just try to parse it with multiple different charset before giving up as there is no real standard what charset to use.
Modifications:
- Add more method overloads to HostsFileParser that take a Charset.
- Try to parse with multiple Charsets in DefaultHostsFileEntriesResolver when windows is used.
- Add unit test
Result:
Fixes https://github.com/netty/netty/issues/8208.
Motivation
There is a cost to concatenating strings and calling methods that will be wasted if the Logger's level is not enabled.
Modifications
Check if Log level is enabled before producing log statement. These are just a few cases found by RegEx'ing in the code.
Result
Tiny bit more efficient code.
