We quoted some strings in the Windows elasticsearch-env script but echo
on Windows includes these quotes in the output. This commit removes
these quotes, they do not need to be output and are noise. Note that one
of the commands is wrapped in parentheses, this is to make obvious that
the space at the end of the corresponding line is intentionally there.
The error message for warning about the use of JAVA_TOOL_OPTIONS on
Windows incorrectly uses $JAVA_TOOL_OPTIONS to dereference the
environment variable JAVA_TOOL_OPTIONS; on Windows it should be
%JAVA_TOOL_OPTIONS%.
The client sniffer depends on the low-level REST client, while the Java high-level REST client and the transport client depend on Elasticsearch itself. Javadoc are not that useful unless they have links to the Elasticsearch classes in the latter case, and to the low-level REST client in the sniffer javadoc. This commit adds those links.
Links to inner classes were using `$` in urls instead of `.`, causing
them to 404.
Also fixes the doc generation code to generate docs into the correct
directory. We moved the docs but never updated the generation code.
* Add REST tests for value_count, stats, extended_stats and cardinality aggs
Also updates the document type of of other agg REST tests to `doc`
Related to #26220
We already added the functionality to create a new keystore on startup
in #26126 but apparently missed to persist the keystore. This change adds
peristence and adds a test for the boostrap loading.
All of the snippets in our docs marked with `// TESTRESPONSE` are
checked against the response from Elasticsearch but, due to the
way they are implemented they are actually parsed as YAML instead
of JSON. Luckilly, all valid JSON is valid YAML! Unfurtunately
that means that invalid JSON has snuck into the exmples!
This adds a step during the build to parse them as JSON and fail
the build if they don't parse.
But no! It isn't quite that simple. The displayed text of some of
these responses looks like:
```
{
...
"aggregations": {
"range": {
"buckets": [
{
"to": 1.4436576E12,
"to_as_string": "10-2015",
"doc_count": 7,
"key": "*-10-2015"
},
{
"from": 1.4436576E12,
"from_as_string": "10-2015",
"doc_count": 0,
"key": "10-2015-*"
}
]
}
}
}
```
Note the `...` which isn't valid json but we like it anyway and want
it in the output. We use substitution rules to convert the `...`
into the response we expect. That yields a response that looks like:
```
{
"took": $body.took,"timed_out": false,"_shards": $body._shards,"hits": $body.hits,
"aggregations": {
"range": {
"buckets": [
{
"to": 1.4436576E12,
"to_as_string": "10-2015",
"doc_count": 7,
"key": "*-10-2015"
},
{
"from": 1.4436576E12,
"from_as_string": "10-2015",
"doc_count": 0,
"key": "10-2015-*"
}
]
}
}
}
```
That is what the tests consume but it isn't valid JSON! Oh no! We don't
want to go update all the substitution rules because that'd be huge and,
ultimately, wouldn't buy much. So we quote the `$body.took` bits before
parsing the JSON.
Note the responses that we use for the `_cat` APIs are all converted into
regexes and there is no expectation that they are valid JSON.
Closes#26233
The secure settings tool reads from stdIn and we use a closure to
provide a value for this. Yet, we evaluate they value too late and end up
with the last provided value for all keys.
* Migrate migration docs from 6.0 to 7.0
Since we only keep one version of migration docs and master is now on 7.0, we
should migrate these so breaking changes can be added in the right place.
* Remove release notes as well
They link to the migration guides, so they have to go.
* Add placeholder notes for 7.0 so doc build is happy
Right now it is possible for the `HttpPipeliningHandler` to queue
pipelined responses. On channel close, we do not clear and release these
responses. This commit releases the responses and completes the promise.
The names of two settings in the script security docs are incorrect,
referring to the prefix as "scripts" instead of "script". This commit
fixes this issue.

Today a `ClusterState.Custom` can be fetched by a transport client and
leaks to the user even if the classes are private etc since the serialized
bytes can be reconstructed. This change adds an option to customs to mark
them as private such that our clusterstate action will never leak it.
We previously added a RuntimeDirectory directive to the systemd service
file for Elasticsearch. This commit adds a packaging test for the
situation that this directive was intended to address.

The AwaitsFix issue has been closed as the deleting an index and recreating with same name will give the
shard a fresh folder to be written to (based on the index uuid).
Due to the weird way of structuring the serialization code in AcknowledgedRequest, many request types forgot to properly serialize the request timeout, for example "index deletion", "index rollover", "index shrink", "putting pipeline", and other requests. This means that if those requests were not directly sent to the master node, the acknowledgement timeout information would be lost (and the default used instead).
Some requests also don't properly expose the timeout mechanism in the REST layer, such as put / delete stored script. This commit fixes all that.
This commit adds a keystore.seed setting that is automatically
generated when the ES keystore is created. This setting may be used by
plugins as a secure, random value. This commit also auto creates the
keystore upon startup to ensure the new setting is always available.
This instruction tells systemd to create a directory /var/run/elasticsearch before starting Elasticsearch.
Without this change, the default PID_DIR (/var/run/elasticsearch) may not exist, and without it, Elasticsearch will fail to start.
Our documentation for the API is:
```
The _upgrade API is no longer useful and will be removed.
Instead, see Reindex to upgrade.
```
Given that, I don't think we need to test the API anymore.
Closes#25311
In #26185 we made the description of `requests_per_second` sane
for reindex. This improves on the description by using some more
common vocabulary ("batch size", etc) and improving the formatting
of the example calculation so it stands out and doesn't require
scrolling.
For the document field equals and hash code tests, we try to mutate the
document field to intentionally produce a document field not equal to
our provided one. We do this by randomly choosing a document field that
has either
- a randomly chosen field name and the same field value as the provided
document field
- a randomly chosen field value and the same field value as the
provided document field
If we are unlucky, it can be that the document field chosen by this
method can be equal to the provided document field. In this case, our
test will fail because the mutation really should be not equal. In this
case, we should simply try the other mutation. Note that random document
field produced by the second method can be equal to the provided
document because it has the same field name and we can get unlucky with
our randomly chosen field values. It is not the case that the random
document field produced by the first method can be equal to the provided
document field; this is because the current implementation guarantees
that the field name length will be different guaranteeing that we have a
different field name. Nevertheless, we fix the issue here by checking
that our random choice gives us a non-equal document field, and assert
that if we got unlucky the other one will work for us.
In a few places we need to lazy initialize static deprecation
loggers. This is needed to avoid touching logging before logging is
configured, but deprecation loggers that are used in foundational
classes like settings and parsers would be initialized before logging is
configured. Previously we used a lazy set once pattern which is fine,
but there's a simpler approach: the holder pattern.

This commits changes the keystore cli add commands to prompt for
creating the keystore if it does not exist. This will make it easier on
users starting out, not having to run a separate command for creation.
An array of values is required because there is no default (or
reasonable way to set a default). But validation for values
only happens if it is actually set. If the values param is omitted
entirely than the agg builder will NPE.
This chance adds several random test infrastructure improvements that caused
issues in on-going developments but are generally useful. For instance is it impossible
to restart a node with a secure setting source since we close it after the node is started.
This change makes it cloneable such that we can reuse it for a restart.
Currently the `percentiles` aggregation allows specifying both possible methods
in the query DSL, but only the later one is used. This changes it to rejecting
such requests with an error. Setting the method multiple times via the java API
still works (and the last one wins).
Closes#26095
This simply removes the default identity hashcode and equals methods in InternalAggregation which where only temporarily put there while we implmeneted the methods in the subclasses.
The node setting `cluster.indices.tombstones.size` was not registered with the settings infrastructure, making it impossible for it to be set by a user.
Closes#26191
For CLI tools, we configure logging without reading the
log4j2.properties file. This because any log statements in a CLI tool
should dump to the console while reading from the log4j2.properties file
would cause them to dump whereever the log configuration there indicates
(e.g., possibly a remote machine). To do this, we added some code to the
base implementation of all CLI tools to configure logging without a
config file. This code is also executed when Elasticsearch starts up. In
the past this was fine yet we previously added detection to
Elasticsearch to find cases where we use logging before it is
configured. Because of configuring logging without a config, this means
we only catch uses of logging before the logging without config is
performed. To correct this, we enable a CLI tool to skip enabling
logging without a config and then in the Elasticsearch CLI we indeed
utilize this to skip configuring logging without a config.

The environment variable CONF_DIR was previously inconsistently used in
our packaging to customize the location of Elasticsearch configuration
files. The importance of this environment variable has increased
starting in 6.0.0 as it's now used consistently to ensure Elasticsearch
and all secondary scripts (e.g., elasticsearch-keystore) all use the
same configuration. The name CONF_DIR is there for legacy reasons yet
it's too generic. This commit renames CONF_DIR to ES_PATH_CONF.

The flood warning checks the wrong threshold, namely the high
watermark. This would impact any node for which the disk usage is above
the high watermark and below the flood stage watermark. This commit
fixes this so that it compares to the flood threshold.
