If the max doc in the index is greater than the minimum total term frequency
among the requested fields we need to adjust max doc to be equal to the min ttf.
This was removed by mistake when fixing #41125.
Closes#41934
This processor uses the lucene HTMLStripCharFilter class to remove HTML
entities from a field. This adds to the char filter, so that there is
possibility to store the stripped version as well.
Note, that the characeter filter replaces tags with a newline, so that
the produced HTML will look slightly different than the incoming HTML
with regards to newlines.
This commit removes manual parsing of JVM options when calculating
ergonomics. This is to avoid a situation that we parse values
differently than the JVM would. In fact, we already have a bug along
these lines today. It is possible to start the JVM with the same flag
multiple times on the command line. In this case, the last value
wins. For example, -Xmx1g -Xmx2g would start the JVM with a heap size of
two gigabytes. Our JVM ergonomics ignores this possibility and instead
the first value is winning!
Our strategy to avoid manual parsing of the JVM options is to start the
Java command line parser (without actually starting a JVM) by invoking
java with the same command line flags as presented and request that the
JVM tell us what values it would start with. This ensures that we have
the correct values when making ergonomic decisions.
Moreover, our strategy also is ignoring ES_JAVA_OPTS which could
override the heap size as well leading to incorrect ergonomic
choices. This commit address this issue too.
The ReadOnlyEngine wraps its reader with a SoftDeletesDirectoryReaderWrapper if soft deletes
are enabled. However the wrapping is done on top of the ElasticsearchDirectoryReader and that
trips assertion later on since the cache key of these directories are different. This commit
changes the order of the wrapping to put the ElasticsearchDirectoryReader first in order to
ensure that it is always retrieved first when we unwrap the directory.
Closes#41795
The deb package has been updated several times in the past to contain
overrides in order to pass lintian inspection. However, there have never
been any tests to ensure we do not fallback to failure. This commit
updates the overrides file given things that have changed since 2.x like
adding ML and bundling the jdk.

* Allow unknown task time in QueueResizingEsTPE
The afterExecute method previously asserted that a TimedRunnable task
must have a positive execution time. However, the code in TimedRunnable
returns a value of -1 when a task time is unknown. Here, we expand the
logic in the assertion to allow for that possibility, and we don't
update our task time average if the value is negative.
* Add a failure flag to TimedRunnable
In order to be sure that a task has an execution time of -1 because of
a failure, I'm adding a failure flag boolean to the TimedRunnable class.
If execution time is negative for some other reason, an assertion will
fail.

- msearch exceptions should be thrown directly instead of wrapping
in a RuntimeException
- Do not allow partial results (where some indices are missing),
instead throw an exception if any index is missing
We currently download 3 variants of the same version of the jdk for
bundling into the distributions. Additionally, the vagrant images do
their own downloading. This commit moves the jdk downloading into a
utility gradle plugin. This will be used in a future PR by the packaging
tests.
The new plugin exposes a "jdks" project extension which allows creating
named jdks. Once the jdk version and platform are set for a named jdk,
the jdk object may be used as a lazy String for the jdk home path, or a
file collection for copying.
We now have coretto on the ephemeral CI images so we can add it to our
regular java test matrix.
On backporting will also add corretto8 to branches that support it.
Prior to this change the ISO8601 date parser would only
parse an optional timezone if seconds were specified.
This change moves the timezone to the same level of
optional components as hour, so that timestamps without
minutes or seconds may optionally contain a timezone.
It also adds a unit test to cover all the supported
formats.
Allows configuring the number of test iterations via IntelliJ's config dialog, instead of having to add it
manually via the tests.iters system property.
Direct the task request to the node executing the task and also refactor the task responses
so all errors are returned and set the HTTP status code based on presence of errors.
The `bulk` threadpool is now called `write`, but `bulk` is still
used in some examples. This commit fixes that.
Also, the only way `threadpool.bulk.write: 30` is a valid increase in the size
of this threadpool is if you have 29 processors, which is an odd number of
processors to have. This commit removes the "more threads" bit.
testclusters detect from settings that security is enabled
if a user is not specified using the DSL introduced in this PR, a default one is created
the appropriate wait conditions are used authenticating with the first user defined in the DSL ( or the default user ).
an example DSL to create a user is user username:"test_user" password:"x-pack-test-password" role: "superuser" all keys are optional and default to the values shown in this example
* terminated_early should always be set in the response with terminate_after
Today we set `terminated_early` to true in the response if the query terminated
early due to `terminate_after`. However if `terminate_after` is smaller than
the number of documents in a shard we don't set the flag in the response indicating
that the query was exhaustive. This change fixes this disprepancy by setting
terminated_early to false in the response if the number of documents that match
the query is smaller than the provided `terminate_after` value.
Closes#33949
In cases where node names and transport addresses can be muddled, it is unclear
that `cluster.initial_master_nodes: master-a:9300` means to look for a node
called `master-a:9300` rather than a node called `master-a` with transport port
`9300`. This commit adds docs to that effect.
Upgrades the AWS SDK to the same version that we're using for the repository-s3 plugin, providing
testing capabilities to override certain SDK endpoints in order to point them to localhost for testing.
Adds tests for the various credential providers.
Today Elasticsearch accepts, but silently ignores, port ranges in the
`discovery.seed_hosts` setting:
```
discovery.seed_hosts: 10.1.2.3:9300-9400
```
Silently ignoring part of a setting like this is trappy. With this change we
reject seed host addresses of this form.
Closes#40786

The settings listed under the "Default values for TLS/SSL settings"
heading are not actual settings, rather they are common suffixes that
are used for settings that exist in a variety of contexts.
This commit changes the way they are presented to reduce this
confusion.

These tests are failing somewhat mysteriously, indicating that when we
renew retention leaess during a restore that our retention leases that
we added before starting the restore suddenly do not exist. To make
sense of this, this commit enables trace logging.
The CircuitBreaker was introduced as means of preventing a
`StackOverflowException` during the build of the AST by the parser.
The ANTLR4 grammar causes a weird behaviour for a Parser Listener.
The `enterEveryRule()` method is often called with a different parsing
context than the respective `exitEveryRule()`. This makes it difficult
to keep track of the tree's depth, and a custom Map was used as an
attempt of matching the contextes as they are encounter during `enter`
and during `exit` of the rules.
This approach had 2 important drawbacks:
1. It's hard to maintain this custom Map as the grammar changes.
2. The CircuitBreaker could often lead to false positives which caused
valid queries to return an Exception and prevent them from executing.
So, this removes completely the CircuitBreaker which is replaced be
a simple handling of the `StackOverflowException`

Today if an exception is thrown when serializing a cluster state during
publication then the master enters a poisoned state where it cannot publish any
more cluster states, but nor does it stand down as master, yielding repeated
exceptions of the following form:

This is because it already created the publication request using
`CoordinationState#handleClientValue()` but then it fails before accepting it.
This commit addresses this by performing the serialization before calling
`handleClientValue()`.
Relates #41090, which was the source of such a serialization exception.
The fractional seconds portion of strict_date_optional_time was

Add a test that stresses concurrent writes using ifSeqno/ifPrimaryTerm to do CAS style updates. Use linearizability checker to verify linearizability. Linearizability of successful CAS'es is guaranteed.
Changed linearizability checker to allow collecting history concurrently.
Changed unresponsive network simulation to wake up immediately when network disruption is cleared to ensure tests proceed in a timely manner (and this also seems more likely to provoke issues).
Because realms are configured at node startup, but license levels can
change dynamically, it is possible to have a running node that has a
particular realm type configured, but that realm is not permitted under
the current license.
In this case the realm is silently ignored during authentication.
This commit adds a warning in the elasticsearch logs if authentication
fails, and there are realms that have been skipped due to licensing.
This message is not intended to imply that the realms could (or would)
have successfully authenticated the user, but they may help reduce
confusion about why authentication failed if the caller was expecting
the authentication to be handled by a particular realm that is in fact
unlicensed.

The `path_match` and `path_unmatch` parameters in dynamic templates match on
object fields in addition to leaf fields. This is not obvious and can cause
surprising errors when a template is meant for a leaf field, but there are
object fields that match. This PR adds a note to the docs to describe the
current behavior.
The run task is supposed to run elasticsearch with the given plugin or
module. However, for modules, this is most realistic if using the full
distribution. This commit changes the run setup to use the default or
oss as appropriate.
We received some feedback that it is not completely clear why `_doc` is present
in the typeless document APIs:
> The new index APIs are PUT {index}/_doc/{id} in case of explicit ids and POST
{index}/_doc for auto-generated ids."_ Isn't this contradicting? Specifying
*types in requests is deprecated*, but we are supposed to still mention *_doc*
in write requests?
This PR updates the 'removal of types' documentation to try to clarify that
`_doc` now represents the endpoint name, as opposed to a type.
Full text queries that start with now are not cacheable if they target a date field.
However we assume in the query builder tests that all queries are cacheable and this assumption
fails when the random generated query string starts with "now". This fails twice in several years
since the probability that a random string starts with "now" is low but this commit ensures that
isCacheable is correctly checked for full text queries that fall into this edge case.

* Revert "Revert "Clean up clusters between tests (#41187)""
This reverts commit 9efc853aa668e285ede733d37b6fc7a0f4b02041.
* Remove the jdk directory to save space on bwc tests
This PR adresses the same concern as #41187 in a different way.
It removes only the JDK from the distribution once the cluster stops,
so we keep the same disk space requirements as before adding the JDK.
This is still a temporary measure, testclusters already deals with this
by doing the equivalent of `cp -l` instead of an actual copy.
