Also adds many `equals` and `hashCode` implementations and moves
the failure printing in `MatchAssertion` into a common spot and
exposes it over `assertEqualsWithErrorMessageFromXContent` which
does an object equality test but then uses `toXContent` to print
the differences.

This PR adds a new option for `host_type`: `tag:TAGNAME` where `TAGNAME` is the tag field you defined for your ec2 instance.
For example if you defined a tag `my-elasticsearch-host` in ec2 and set it to `myhostname1.mydomain.com`, then
setting `host_type: tag:my-elasticsearch-host` will tell Discovery Ec2 plugin to read the host name from the
`my-elasticsearch-host` tag. In this case, it will be resolved to `myhostname1.mydomain.com`.
Closes#22566.
Today we cache query results even if the query timed out. This is obviously
problematic since results are not complete. Yet, the decision if a query timed
out or not happens too late to simply not cache the result since if we'd just throw
an exception all currently waiting requests with the same request / cache key would
fail with the same exception without the option to access the result or to re-execute.
Instead, this change will allow the request to enter the cache but invalidates it immediately.
Concurrent request might not get executed and return the timed out result which is not absolutely
correct but very likely since identical requests will likely timeout as well. As a side-effect
we won't hammer the node with concurrent slow searches but rather only execute one of them
and return shortly cached result.
Closes#22789
Adds "Appending B. Painless API Reference", a reference of all classes
and methods available from Painless. Removes links to java packages
because they contain methods that we don't expose and don't contain
methods that we do expose (the ones in Augmentation). Instead this
generates a list of every class and every exposed method using the same
type information available to the
interpreter/compiler/whatever-we-call-it. From there you can jump to
the relevant docs.
Right now you build all the asciidoc files by running
```
gradle generatePainlessApi
```
These files are expected to be committed because we build the docs
without running `gradle`.
Also changes the output of `Debug.explain` so that it is easy to
search for the class in the generated reference documentation.
You can also run it in an IDE safely if you pass the path to the
directory in which to generate the docs as the first parameter. It'll
blow away the entire directory an recreate it from scratch so be careful.
And then you can build the docs by running something like:
```
../docs/build_docs.pl --out ../built_docs/ --doc docs/reference/index.asciidoc --open
```
That is, if you have checked out https://github.com/elastic/docs in
`../docs`. Wait a minute or two and your browser will pop open in with
all of Elasticsearch's reference documentation. If you go to
`http://localhost:8000/painless-api-reference.html` you can see this
list. Or you can get there by following the links to `Modules` and
`Scripting` and `Painless` and then clicking the link in the paragraphs
below titled `Appendix B. Painless API Reference`.
I like having these in asciidoc because we can deep link to them from the
rest of the guide with constructs like
`<<painless-api-reference-Object-hashCode-0>>` and
`<<painless-api-reference->>` and we get link checking. Then the only
brittle link maintenance bit is the link generation for javadoc. Which
sucks. But I think it is important that we link to the methods directly
so they are easy to find.

The output of the ElasticsearchException.generateThrowableXContent() method can be parsed back by the ElasticsearchException.fromXContent() method.
This commit adds unit tests in the style of the to-and-from-xcontent tests we already have for other parsing methods. It also relax the strict parsing of the ElasticsearchException.fromXContent() so that it does not throw an exception when custom metadata and headers are parsed, as long as they are either strings or arrays of strings. Every other type is ignored at parsing time.
Some tests verify that all connection have been closed but due to the
async / concurrent nature of `RemoteClusterConnection` there are situations
where we notify listeners that trigger tests to finish before we actually
closed all connections. The race is very very small and has no impact on the
code correctness. This commit documents and improves the way we close
connections to ensure test won't fail with false positives.
Closes#22803
This commit removes the search type `dfs_query_and_fetch` without a
replacement. We don't allow to use this type via REST since 2.x
but still keep it around for no particular reason. There we no users
complaining about the availability. This should now be removed from the
codebase. `query_and_fetch` is still used internally to safe a roundtrip
if there is only one shard but it can't be used via the rest interface.
This is related to #22116. URLRepository requires SocketPermission
connect. This commit introduces a new module called "repository-url"
where URLRepository will reside. With the new module, permissions can
be removed from core.
Beforehand, the DateProcessor constructs its joda pattern formatter during processor
construction. This led to newly ingested documents being defaulted to
the year that the pipeline was constructed, not that of processing.
Fixes#22547.
Add unit tests for `TopHitsAggregator` and convert some snippets in
docs for `top_hits` aggregation to `// CONSOLE`.

Previous to his change when the range query was rewritten to an unbounded range (`[* TO *]`) it maintained the timezone and format for the query. This means that queries with different timezones and format which are rewritten to unbounded range queries actually end up as different entries in the search request cache.
This is inefficient and unnecessary so this change nulls the timezone and format in the rewritten query so that regardless of the timezone or format the rewritten query will be the same.
Although this does not fix#22412 (since it deals with the WITHIN case rather than the INTERSECTS case) it is born from the same arguments
These files should have been removed in an earlier commit. This commit also simplifies usage of ProgressLoggerWrapper by using the Groovy delegation instead of using explicit delegation.
5.3.0 is the first version that contains the split from headers to metadata, updated the check to reflect that. It was previously after to be able to commit to master first, and only after that backport the change. Otherwise master tests would have failed until the change was backported.
Previously the behavior where the `OpType` byte was serialized was only in
master, but it was recently backported to 5.x, so the serialization version
checks need to be updated as well.
This adds the necessary `AuthCache` needed to support preemptive authorization. By adding every host to the cache, the automatically added `RequestAuthCache` interceptor will add credentials on the first pass rather than waiting to do it after _each_ anonymous request is rejected (thus always sending everything twice when basic auth is required).
move "es." internal headers to separate metadata set in ElasticsearchException and stop returning them as response headers
Closes#17593
* [TEST] remove ESExceptionTests, move its methods to ElasticsearchExceptionTests or ExceptionSerializationTests
Docker cgroups are mounted in the wrong place (i.e., inconsistently with
/proc/self/cgroup). This commit adds an undocumented hack for working
around, for now.

As a follow up to #22649, this changes the resent tests for parsing parts of search
responses to randomly set the humanReadable() flag of the XContentBuilder that
is used to render the responses. This should help to test that we can parse back
thoses classes if the user specifies `?human=true` in the request url.
Instead of using Gradle-version specific compilation options, use distinct source sets. This also allows compilation of buildSrc/build-tools under IDEs that
don't understand the version-specific compilation options.

This changes build files so that building Elasticsearch works with both Gradle 2.13 as well as higher versions of Gradle (tested 2.14 and 3.3), enabling a smooth transition from Gradle 2.13 to 3.x.
In some cases (apparently with outlook files), mime4j library is needed.
We removed it in the past which can cause elasticsearch to crash when you are using ingest-attachment (and probably mapper-attachments as well in 2.x series) with a file which requires this library.
Similar problem as the one reported at #22077.
This commit replaces specialized functional interfaces in various
plugins with generic options. Instead of creating `StorageRunnable`
interfaces in every plugin we can just use `Runnable` or `CheckedRunnable`.
There was a typo in the `ParseField` declaration. I know
we want to port these parsers to `ObjectParser` eventually
but I don't have the energy for that today and want to get
this fixed.
