This commit puts all the classes in the repository-s3 plugin into a
single package. In addition to simplifying the plugin, it will make it
easier to test as things that should be package private will not be
difficult to use inside tests alone.
This commit makes closing a ReleasableBytesStreamOutput release the underlying BigArray so
that we can use try-with-resources with these streams and avoid leaking memory by not returning
the BigArray. As part of this change, the ReleasableBytesStreamOutput adds protection to only release the BigArray once.
In order to make some of the changes cleaner, the ReleasableBytesStream interface has been
removed. The BytesStream interface is changed to a abstract class so that we can use it as a
useable return type for a new method, Streams#flushOnCloseStream. This new method wraps a
given stream and overrides the close method so that the stream is simply flushed and not closed.
This behavior is used in the TcpTransport when compression is used with a
ReleasableBytesStreamOutput as we need to close the compressed stream to ensure all of the data
is written from this stream. Closing the compressed stream will try to close the underlying stream
but we only want to flush so that all of the written bytes are available.
Additionally, an error message method added in the BytesRestResponse did not use a builder
provided by the channel and instead created its own JSON builder. This changes that method to use the channel builder and in turn the bytes stream output that is managed by the channel.
This commit renames the random ASCII helper methods in ESTestCase. This
is because this method ultimately uses the random ASCII methods from
randomized runner, but these methods actually only produce random
strings generated from [a-zA-Z].

This commit adds a description for a parameter that was added to
BootstrapChecks#enforceLimits(BoundTransportAddress, String) without the
Javadocs having been updated.
While there are use-cases where a single-node is in production, there
are also use-cases for starting a single-node that binds transport to an
external interface where the node is not in production (for example, for
testing the transport client against a node started in a Docker
container). It's tricky to balance the desire to always enforce the
bootstrap checks when a node might be in production with the need for
the community to perform testing in situations that would trip the
bootstrap checks. This commit enables some flexibility for these
users. By setting the discovery type to "single-node", we disable the
bootstrap checks independently of how transport is bound. While this
sounds like a hole in the bootstrap checks, the bootstrap checks can
already be avoided in the single-node use-case by binding only HTTP but
not transport. For users that are genuinely in production on a
single-node use-case with transport bound to an external use-case, they
can set the system property "es.enable.bootstrap.checks" to force
running the bootstrap checks. It would be a mistake for them not to do
this.

This change adds a setting property that sets the value of a setting as final.
Updating a final setting is prohibited in any context, for instance an index setting
marked as final must be set at index creation and will refuse any update even if the index is closed.
This change also marks the setting `index.number_of_shards` as Final and the special casing for refusing the updates on this setting has been removed.
the test reduce the wait for initial cluster state to 0, causing multiple nodes to be start while elections are going on. This means there is a chance of a split election which shouldn't cause the test to time out.
This commit adds a single node discovery type. With this discovery type,
a node will elect itself as master and never form a cluster with another
node.

When terminating an executor service or a thread pool, we first
shutdown. Then, we do a timed await termination. If the await
termination fails because there are still tasks running, we then
shutdown now. However, this method does not wait for actively executing
tasks to terminate, so we should again wait for termination of these
tasks before returning. This commit does that.

If a test touches ElasticsearchExceptionHandle before the class
initialzer for ElasticsearchException has run, a circular class
initialization problem can arise. Namely, the class initializer for
ElasticsearchExceptionHandle depends on the class initializer for
ElasticsearchExceptionHandle which depends on the class initializer for
all the classes that extend ElasticsearchException, but these classes
can not be loaded because ElasticsearchException has not finished its
class initializer. There are tests that can trigger this before
ElasticsearchException has been loaded due to an unlucky ordering of
test execution. This commit addresses this issue by making
ElasticsearchExceptionHandle private, and then exposing methods that
provide the necessary values from ElasticsearchExceptionHandle. Touching
these methods will force the class initializer for
ElasticsearchException to run first.
Fielddata can no longer be configured to be loaded eagerly (it only accepts
`true` and `false`), so this line is a little misleading because it talks about
a procedure we can no longer do.
It starts nodes in any order and thus it disabled the wait for first cluster state at node start up time
the later is required for the auto management logic.
Closes#23728
With this commit, Azure repositories are now using an Exponential Backoff policy before failing the backup.
It uses Azure SDK default values for this policy:
* `30s` delta backoff base with
* `3s` min
* `90s` max
* `3` retries max
Users can define the number of retries they wish by setting `cloud.azure.storage.xxx.max_retries` where `xxx` is the azure named account.
Closes#22728.
Currently for field sorting we always use a custom sort field and a custom comparator source.
Though for numeric fields this custom sort field could be replaced with a standard SortedNumericSortField unless
the field is nested especially since we removed the FieldData for numerics.
We can also use a SortedSetSortField for string sort based on doc_values when the field is not nested.
This change replaces IndexFieldData#comparatorSource with IndexFieldData#sortField that returns a Sorted{Set,Numeric}SortField when possible or a custom
sort field when the field sort spec is not handled by the SortedSortFields.
Today we prevent nodes from joining when indices exists that are too old.
Yet, the opposite can happen too since lucene / elasticsearch is not forward
compatible when it gets to indices we won't let nodes join the cluster once
there are indices in the clusterstate that are newer than the nodes version.
This prevents forward compatibility issues which we never test against. Yet,
this will not prevent rolling restarts or anything like this since indices
are always created with the minimum node version in the cluster such that an index
can only get the version of the higher nodes once all nodes are upgraded to this version.
TopDocs et.al. got additional parameters to incrementally reduce
top docs. In order to add incremental reduction `CollapseTopFieldDocs`
needs to have the same properties.
Converts the analysis docs to that were marked as json into `CONSOLE`
format. A few of them were in yaml but marked as json for historical
reasons. I added more complete examples for a few of the less obvious
sounding ones.

The method Boolean#getBoolean is dangerous. It is too easy to mistakenly
invoke this method thinking that it is parsing a string as a
boolean. However, what it actually does is get a system property with
the specified string, and then attempts to use usual crappy boolean
parsing in the JDK to parse that system property as boolean with
complete leniency (it parses every input value into either true or
false); that is, this method amounts to invoking
Boolean#parseBoolean(String) on the result of
System#getProperty(String). Boo. This commit bans usage of this method.

The pattern-analyzer docs contained a snippet that was an expanded
regex that was marked as `[source,js]`. This changes it to
`[source,regex]`.
The htmlstrip-charfilter and pattern-replace-charfilter docs had
examples that were actually a list of tokens but marked `[source,js]`.
This marks them as `[source,text]` so they don't count as unconverted
CONSOLE snippets.
The pattern-replace-charfilter also had a doc who's test was
skipped because of funny interaction with the test framework. This
fixes the test.
Three more down, eighty-two to go.

CONSOLEifies the lang-analyzer docs and replaces the (invalid)
empty `keyword_marker` setups that were on the page with one
that contains the word "example" translated into the appropriate
language.

Remote nodes in cross-cluster search can be marked as eligible for
acting a gateway node via a remote node attribute setting. For example,
if search.remote.node.attr is set to "gateway", only nodes that have
node.attr.gateway set to "true" can be connected to for cross-cluster
search. Unfortunately, there is a bug in the handling of these
attributes due to the use of a dangerous method
Boolean#getBoolean(String) which obtains the system property with
specified name as a boolean. We are not looking at system properties
here, but node settings. This commit fixes this situation, and adds a
test. A follow-up will ban the use of Boolean#getBoolean.

This commit changes the ClusterStatsNodes.NetworkTypes so that is does
not print out empty field names when no Transport or HTTP type is defined:
```
{
"network_types": {
...
"http_types": {
"": 2
}
}
}
```
is now rendered as:
```
{
"network_types": {
...
"http_types": {
}
}
}
```
SearchPhaseController is tighly coupled to AtomicArray which makes
non-dense representations of results very difficult. This commit removes
the coupling and cuts over to Collection rather than List to ensure no
order or random access lookup is implied.
This change introduces a new API called `_field_caps` that allows to retrieve the capabilities of specific fields.
Example:
````
GET t,s,v,w/_field_caps?fields=field1,field2
````
... returns:
````
{
"fields": {
"field1": {
"string": {
"searchable": true,
"aggregatable": true
}
},
"field2": {
"keyword": {
"searchable": false,
"aggregatable": true,
"non_searchable_indices": ["t"]
"indices": ["t", "s"]
},
"long": {
"searchable": true,
"aggregatable": false,
"non_aggregatable_indices": ["v"]
"indices": ["v", "w"]
}
}
}
}
````
In this example `field1` have the same type `text` across the requested indices `t`, `s`, `v`, `w`.
Conversely `field2` is defined with two conflicting types `keyword` and `long`.
Note that `_field_caps` does not treat this case as an error but rather return the list of unique types seen for this field.
