f194aedbf0 Close delegate resolver from RoundRobinInetAddressResolver (#9214)
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.

d17bd5e160 Adding support for whitespace in resource path in tests (#8606)
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

Allow to parse hosts file which is stored in a different encoding then the default system encoding. (#8211)
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.

Replace toArray(new T[size]) with toArray(new T[0]) to eliminate zero-out and allow the VM to optimize. (#8075)
Motivation:

Using toArray(new T[0]) is usually the faster aproach these days. We should use it.

See also https://shipilev.net/blog/2016/arrays-wisdom-ancients/#_conclusion.

Modifications:

Replace toArray(new T[size]) with toArray(new T[0]).

Result:

Faster code.

3e3e5155b9 Check if Log level is enabled before creating log statements (#8022)
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.

e8540c2b7a Adding stable JDK9 module names that follow reverse-DNS style
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.

fbf0e5f4dd Prefer JDK ThreadLocalRandom implementation over ours.
Motivation:

We have our own ThreadLocalRandom implementation to support older JDKs . That said we should prefer the JDK provided when running on JDK >= 7

Modification:

Using ThreadLocalRandom implementation of the JDK when possible.

Result:

Make use of JDK implementations when possible.

b91dd0678d Resolver package is unstable
Motivation:
The resolver package had some changes late in the 4.1.CR phase and the intention was to mark this package as unstable until these interfaces solidify, but we forgot to mark the package and public classes with the unstable annotation.

Modifications:
- resolver package public interfaces and package-info should be annotated with @UnstableApi

Result:
The unstable nature of the resolver package is more clearly communicated.

81f9de423c HostsFileParser should allow both IPv4 and IPv6 for a given host
Motivation:

HostsFileParser only retains the first address for each given hostname.
This is wrong, and it’s allowed to have both an IPv4 and an IPv6.

Modifications:

* Have `HostsFileParser` now return a `HostsFileEntries` that contains IPv4 entries and IPv6 entries
* Introduce `ResolvedAddressTypes` to describe resolved address types preferences
* Add a new `ResolvedAddressTypes` parameter to `HostsFileEntriesResolver::address` to account for address types preferences
* Change `DnsNameResolver` constructor to take a `ResolvedAddressTypes`, allowing for a null value that would use default
* Change `DnsNameResolverBuilder::resolvedAddressTypes` to take a `ResolvedAddressTypes`
* Make `DnsNameResolver::resolvedAddressTypes` return a `ResolvedAddressTypes`
* Add a static `DnsNameResolverBuilder::computeResolvedAddressTypes` to ease converting from `InternetProtocolFamily`

Result:

We now support hosts files that contains IPv4 and IPv6 pairs for a same
hostname.

007048dddd DnsNameResolver empty/null hostname missed by a416b79
Motivation:
a416b79 introduced a check for null or empty host name to be compatible with the JDK resolution. However the doResolve(String, Promise) method, and if the doResolve(String, DnsRecord[], Promise, DnsCache) method was overridden the empty/null hostname would not be correctly resolved.

Modifications:
- Move the empty/null host name check into the lowest level doResolve method in DnsNameResolver
- Remove the duplicate logic in InetNameResolver.java which can be bypassed anyways

Result:
By default (unless behavior is overridden) DnsNameResolver resolves null/empty host names to local host just like the JDK.

a416b79d86 DnsNameResolver.resolve*(...) never notifies the Future when empty hostname is used.
Motivation:

When an empty hostname is used in DnsNameResolver.resolve*(...) it will never notify the future / promise. The root cause is that we not correctly guard against errors of IDN.toASCII(...) which will throw an IllegalArgumentException when it can not parse its input. That said we should also handle an empty hostname the same way as the JDK does and just use "localhost" when this happens.

Modifications:

- If the try to resolve an empty hostname we use localhost
- Correctly guard against errors raised by IDN.toASCII(...) so we will always noify the future / promise
- Add unit test.

Result:

DnsNameResolver.resolve*(...) will always notify the future.

3344cd21ac Wrap operations requiring SocketPermission with doPrivileged blocks
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.

4e2530c171 fix 5868 -fix DefaultHostsFileEntriesResolverTest to pass on windows 7
Motivation:

Windows 7 hosts file is empty by default (at least on my machine? see
http://serverfault.com/questions/4689/windows-7-localhost-name-resolution-is-handled-within-dns-itself-why
for details and reasoning.

the test relies on the file containing an entry for localhost.

Modifications:

refactor class code to 1st normalize the input host name and then look it up, change the test to verify
that hostnames are normalized in a case-insensitive way before being looked up (which was the intent
of the original test)

Result:

test should pass on vanilla windows 7 (and any other machine with no
localhost in the hosts file). no effect anywhere else or on actual netty
code.

4bce554c90 Revert counter optimization in RoundRobin until better implementation found 2016-11-17 11:28:09 -08:00
Dmitry Spikhalskiy
5eebe9a06c Implement RoundRobin logic in RoundRobinInetAddressResolver#resolveAll
Motivation:
Now the ```resolveAll``` method of RoundRobinInetAddressResolver returns results without any rotation and shuffling. As a result, it doesn't force any round-robin for clients that get a result of ```resolveAll``` and use addresses from the result one by one for a connection establishing until success. This commit implements round-robin in RoundRobinInetAddressResolver#resolveAll. These improvements inspired by the discussion here: https://github.com/AsyncHttpClient/async-http-client/issues/1285

Modifications:
Rotate collection from internal ```resolveAll``` call by index, which is incremented every call to RoundRobinInetAddressResolver#resolveAll method.
Random replaced by an incrementing counter, which makes code cheaper and guarantees predictable address order in tests.

Result:
Improved ```RoundRobinInetAddressResolver``` is compatible with clients that use ```resolveAll``` result.

eb7f8e4dc5 Expose RoundRobinInetAddressResolver
Motivation:
Make small refactoring for recently merged PR #5867 to make the code more flexible and expose aggressive round robin as a NameResolver too with proper code reuse.

Modifications:
Round robin is a method of hostname resolving - so Round robin related code fully moved to RoundRobinInetAddressResolver implements NameResolver<InetAddress>, RoundRobinInetSocketAddressResolver is deleted as a separate class, instance with the same functionality could be created by calling #asAddressResolver.

Result:
New forced Round Robin code exposed not only as an AddressResolver but as a NameResolver too, more proper code and semantic reusing of InetNameResolver and InetSocketAddressResolver classes.

efd118ddec Support aggressive round-robin dns
Motivation:

Suppose the domain `foo.example.com` resolves to the following ip
addresses `10.0.0.1`, `10.0.0.2`, `10.0.0.3`. Round robin DNS works by
having each client probabilistically getting a different ordering of
the set of target IP’s, so connections from different clients (across
the world) would be split up across each of the addresses. Example: In
a `ChannelPool` to manage connections to `foo.example.com`, it may be
desirable for high QPS applications to spread the requests across all
available network addresses. Currently, Netty’s resolver would return
only the first address (`10.0.0.1`) to use. Let say we are making
dozens of connections. The name would be resolved to a single IP and
all of the connections would be made to `10.0.0.1`. The other two
addresses would not see any connections. (they may see it later if new
connections are made and `10.0.0.2` is the first in the list at that
time of a subsequent resolution). In these changes, I add support to
select a random one of the resolved addresses to use on each resolve
call, all while leveraging the existing caching and inflight request
detection. This way in my example, the connections would be make to
random selections of the resolved IP addresses.

Modifications:

I added another method `newAddressResolver` to
`DnsAddressResolverGroup` which can be overriden much like
`newNameResolver`. The current functionality which creates
`InetSocketAddressResolver` is still used. I added
`RoundRobinDnsAddressResolverGroup` which extends
DnsAddressResolverGroup and overrides the `newAddressResolver` method
to return a subclass of the `InetSocketAddressResolver`. This subclass
is called `RoundRobinInetSocketAddressResolver` and it contains logic
that takes a `resolve` request, does a `resolveAll` under the hood, and
returns a single element at random from the result of the `resolveAll`.

Result:

The existing functionality of `DnsAddressResolverGroup` is left
unchanged. All new functionality is in the
`RoundRobinInetSocketAddressResolver` which users will now have the
option to use.

24784bfcd1 Change hosts file resolver to be case-insensitive
Motivation:

Resolving hosts via the /etc/hosts file should be case-insensitive, e.g. localhost and LOCALHOST refer to the same host, this is the same that is applied to dns queries.

Modifications:

Store hosts Map with lowercase keys, lookup the keys as lowercase
Add to unit test for the hosts file parser to use an UPPERCASE file entry
