Added missing CONSOLE scripts to documentation for sampler and diversified_sampler aggs.
Includes new StackOverflow index setup in build.gradle
Closes#22746
* Formatting tweaks
In #22762, settings preparation during bootstrap was changed slightly to
account for SecureSettings, by starting with a fresh settings builder
after reading the initial configuration. However, this the defaults from
system properties were never re-read. This change fixes that bug (which
was never released).
closes#22861
This change removes the ability to set region for s3 repositories.
Endpoint should be used instead if a custom s3 location needs to be
used.
closes#22758
Usually the order in which we serialize sets and maps of things doesn't matter,
but since InnerHitBuilder is part of SearchSourceBuilder, which is in turn used
as a cache key in its bytes serialization, we need to ensure the order of all
these fields when writing them to an output stream.
This adds tests and makes sure we iterate over the scriptField set and the
childInnerHits map in a fixed order.
Closes#22808
Follow up of #22857 where we deprecate automatic creation of azure containers.
BTW I found that the `AzureSnapshotRestoreServiceIntegTests` does not bring any value because it runs basically a Snapshot/Restore operation on local files which we already test in core.
So instead of trying to fix it to make it pass with this PR, I simply removed it.
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 moves the building blocks for delete by query into core. This
should enabled two thigns:
1. Plugins other than reindex to implement "bulk by scroll" style
operations.
2. Plugins to directly call delete by query. Those plugins should
be careful to make sure that task cancellation still works, but
this should be possible.
Notes:
1. I've mostly just moved classes and moved around tests methods.
2. I haven't been super careful about cohesion between these core
classes and reindex. They are quite interconnected because I wanted
to make the change as mechanical as possible.
Closes#22616
This is related to #22116. The repository-hdfs plugin opens socket
connections. As SocketPermission is transitioned out of core, hdfs
will require connect permission. This pull request wraps operations
that require this permission in doPrivileged blocks.
* S3 repository: Add named configurations
This change implements named configurations for s3 repository as
proposed in #22520. The access/secret key secure settings which were
added in #22479 are reverted, and the only secure settings are those
with the new named configs. All other previously used settings for the
connection are deprecated.
closes#22520
This migration script existed from moving plugins into the ES repo in
2.0. It is no longer needed (and contains eg maven commands), and if we
did need any part of it, it will still exist in git history.
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 commit introduces sequence-number-based recovery. When a replica
has fallen out of sync, rather than performing a file-based recovery we
first attempt to replay operations since the last local checkpoint on
the replica. To do this, at the start of recovery the replica tells the
primary what its local checkpoint is. The primary will then wait for all
operations between that local checkpoint and the current maximum
sequence number to complete; this is to ensure that there are no gaps in
the operations that will be replayed from the primary to the
replica. This is a best-effort attempt as we currently have no
guarantees on the primary that these operations will be available; if we
are not able to replay all operations in the desired range, we just
fallback to file-based recovery. Later work will strengthen the
guarantees.

At this point AbstractSearchAsyncAction is just a base-class for the first phase of a search where we have multiple replicas
for each shardID. If one of them is not available we move to the next one. Yet, once we passed that first stage we have to work with
the shards we succeeded on the initial phase.
Unfortunately, subsequent phases are not fully detached from the initial phase since they are all non-static inner classes.
In future changes this will be changed to detach the inner classes to test them in isolation and to simplify their creation.
The AbstractSearchAsyncAction should be final and it should just get a factory for the next phase instead of requiring subclasses
etc.
This commit adds a ElasticsearchException.failureFromXContent() that can be used to parse the result of ElasticsearchException.generateFailureXContent().
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.
