The rest test framework, because it used to be tightly integrated with
ESIntegTestCase, currently expects the addresses for the test cluster to
be passed using the transport protocol port. However, it only uses this
to then find the http address.
This change makes ESRestTestCase extend from ESTestCase instead of
ESIntegTestCase, and changes the sysprop used to tests.rest.cluster,
which now takes the http address.

We have two similar tests with the same name, ContextAndHeaderTransportTests.
They shared lots of common code so I extracted much of it into
ActionRecordingPlugin, a plugin which records all action requests for later
inspection.
I also removed all the warnings from both tests. That made lang-mustache
compile cleanly without any custom -Xlint so I removed those. To remove
the warnings I had to add type parameters to ActionFilter which seemed
like a good idea anyway.
Removes all Xlint skips in lang-plan-a. Warnings were just some extra
casts which were removed, some raw types which we just needed to <?>, and
a couple of unchecked casts in data that we know to be Map<String, Object>
because that structure is super-ultra-common in scripts.
1. Gets guice out of the business of building ScoreFunctionParsers and
QueryParsers.
2. Moves QueryParser registration to SearchModule
3. Moves NamedWriteableRegistry construction out of guice and into Node and
TransportClient.
4. Moves shape registration into SearchModule so now all named writeable
registration is done in the SearchModule.
This is breaking for plugin authors. Instead of declaring new QueryParser
like:
```java
public void onModule(IndicesModule module) {
module.registerQueryParser(NewQueryParser.class);
}
```
you do it like:
```java
public void onModule(SearchModule module) {
module.registerQueryParser(NewQueryParser::new);
}
```
The QueryParser's argument no longer come from @Inject, now they come from
the declaration in the plugin. The above example is for a no-arg QueryParser.
Most of the QueryParsers in Elasticsearch are no-arg.
ScoreFunctionParsers have a similar but slightly different change. This:
```java
public void onModule(SearchModule module) {
module.registerFunctionScoreParser(NewFunctionScoreParser.class);
}
```
becomes
```java
public void onModule(SearchModule module) {
module.registerFunctionScoreParser(new NewFunctionScoreParser());
}
```
Since all known ScoreFunctionParsers have no arg constructors its simpler to
just build them at registration time rather than specify a supplier that is
used to build them later.
This commit modifies the load_average in the node stats API response
to be an object containing the one-minute, five-minute and
fifteen-minute load averages as fields (if those values are
available). Additionally, this commit modifies the cat nodes API
response to format the one-minute, five-minute and fifteen-minute load
averages as null if any of the respective values are not available.
Setting realTime to false in the get term vector request ensures,
that after a refresh the document is not fetched from the translog,
which seems to yield different in rare test runs.
The change likely triggering this was introduced in #15933
This commit adds some additional assertions that test success is not
falsely indicated by adding assertions that success / failure methods
are not incorrectly invoked in failure / success scenarios.
This commit adds a test for calculating the age of PrioritizedRunnable
that allows real clock time to elapse. The test ensures that at least
one millisecond has passed, and that the resolution of System#nanoTime
on the underlying system is actually able to detect this.

This commit wraps a trace logging message in a trace logging level check
to prevent allocating an Object array (to hold the logging parameters)
and a String (from the interval) when trace logging is not enabled every
second (with the default index refresh interval) and every five seconds
(with the default translog sync interval) for every open index when
trace logging is not enabled.
This commit simplifies an equality test in IndexShard#sameException
where the messages for two exceptions are being compared. The previous
condition first tested logical equality if the left exception is not
null, and otherwise tested reference equality. There is a convenience
method since JDK 7 for testing equality in this way: Objects#equals.
Closes#16025
Fixes an issue caused by trying to add a LeafReader for a closed index to
ShardCoreKeyMap. It add itself to the map half way before throwing
AlreadyClosedException, leaking some references and causesing Elasticsearch
to refuse to shut down cleanly when testing.
This commit enhances the master channel exception test in
o.e.c.a.s.ShardStateActionTests to test that a retries loop as expected
when requests to the master repeatedly fail.
It had some funky errors, like lenient:true not working and queries with
two integer fields blowing up if there was no analyzer defined on the
query. This throws a bunch more tests at it and rejiggers how non-strings
are handled so they don't wander off into scary QueryBuilder-land unless
they have a nice strong analyzer to protect them.
This commit adds a trace log on a cluster state update while waiting for
a new master, and changes the log level on cluster service close to the
warn level.
This commit tightens the tests in o.e.c.a.s.ShardStateActionTests:
- adds a simple test for a success condition that validates the shard
failed request is correct and sent to the correct place
- remove redundant assertions from the no master and master left tests
- an assertion that success is not falsely indicated in the case of a
unhandled error
This commit addresses a time unit conversion bug in calculating the age
of a PrioritizedRunnable. The issue was an incorrect conversion from
nanoseconds to milliseconds as instead the conversion was to
microseconds. This leads to the timeInQueue metric for pending tasks to
be off by three orders of magnitude.
We have a performance bug that if a filter aggregation is below a terms
aggregation that has a cardinality of 1000, we will call Query.createWeight
1000 times as well. However, Query.createWeight can be a costly operation.
For instance in the case of a TermQuery it will seek the term in every
segment. Instead, we should create the Weight once, and then get as many
iterators as we need from this Weight.
I found this problem while trying to diagnose a performance regression while
upgrading from 1.7 to 2.1[1]. While the problem was not introduced in 2.x, the
fact that 1.7 cached very aggressively had hidden this problem, since you don't
need to seek the term anymore on a cached TermFilter.
Doing things once for every aggregator is not easy with the current API but
I discussed this with Colin and Aggregator factories will need to get an init
method for different reasons, where we will be able to put these steps that
need to be performed only once, no matter haw many aggregators need to be
created.

With this commit we do not check only if an endpoint is up but
we also check that the cluster status is green. Previously,
builds sporadically failed to pass this condition.
If an operating system reports -1 for the total bytes of a filesystem
path, we should ignore it when capturing the least and most available
statistics.
