Motivation:
HTTP is a plaintext protocol which means that someone may be able
to eavesdrop the data. To prevent this, HTTPS should be used whenever
possible. However, maintaining using https:// in all URLs may be
difficult. The nohttp tool can help here. The tool scans all the files
in a repository and reports where http:// is used.
Modifications:
- Added nohttp (via checkstyle) into the build process.
- Suppressed findings for the websites
that don't support HTTPS or that are not reachable
Result:
- Prevent using HTTP in the future.
- Encourage users to use HTTPS when they follow the links they found in
the code.
Motivation:
LGTM reports multiple issues. They need to be triaged,
and real ones should be fixed.
Modifications:
- Fixed multiple issues reported by LGTM, such as redundant conditions,
resource leaks, typos, possible integer overflows.
- Suppressed false-positives.
- Added a few testcases.
Result:
Fixed several possible issues, get rid of false alarms in the LGTM report.
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
