Moves the test infrastructure away from using node.max_local_storage_nodes, allowing us in a
follow-up PR to deprecate this setting in 7.x and to remove it in 8.0.
This also changes the behavior of InternalTestCluster so that starting up nodes will not automatically
reuse data folders of previously stopped nodes. If this behavior is desired, it needs to be explicitly
done by passing the data path from the stopped node to the new node that is started.
Simplifies the voting configuration reconfiguration logic by switching to an explicit Comparator for
the priorities. Does not make changes to the behavior of the component.
Flushing at the end of a peer recovery (if needed) can bring these
benefits:
1. Closing an index won't end up with the red state for a recovering
replica should always be ready for closing whether it performs the
verifying-before-close step or not.
2. Good opportunities to compact store (i.e., flushing and merging
Lucene, and trimming translog)
Closes#40024Closes#39588
This change verifies and aborts recovery if source and target have the
same syncId but different sequenceId. This commit also adds an upgrade
test to ensure that we always utilize syncId.
The verifying-before-close step ensures the global checkpoints on all
shard copies are in sync; thus, we don' t need to sync global
checkpoints for closed indices.

There is an off-by-one error in this test. It leads to the recovery
thread never being started, and that means joining on it will wait
indefinitely. This commit addresses that by fixing the off-by-one error.

I forgot to git add these before pushing, sorry. This commit fixes
compilation in IndexShardTests, they are needed here and not in master
due to differences in how Java infers types in generics between JDK 8
and JDK 11.
Today when executing an action on a primary shard under permit, we do
not enforce that the shard is in primary mode before executing the
action. This commit addresses this by wrapping actions to be executed
under permit in a check that the shard is in primary mode before
executing the action.
Today we are persisting the retention leases at least every thirty
seconds by a scheduled background sync. This sync causes an fsync to
disk and when there are a large number of shards allocated to slow
disks, these fsyncs can pile up and can severely impact the system. This
commit addresses this by only persisting and fsyncing the retention
leases if they have changed since the last time that we persisted and
fsynced the retention leases.
* Cleanup Various Uses of ActionListener
* Use shorter `map`, `runAfter` or `wrap` where functionally equivalent to anonymous class
* Use ActionRunnable where functionally equivalent
Downgrading an Elasticsearch node to an earlier version is unsupported, because
we do not make any attempt to guarantee that a node can read any of the on-disk
data written by a future version. Yet today we do not actively prevent
downgrades, and sometimes users will attempt to roll back a failed upgrade with
an in-place downgrade and get into an unrecoverable state.
This change adds the current version of the node to the node metadata file, and
checks the version found in this file against the current version at startup.
If the node cannot be sure of its ability to read the on-disk data then it
refuses to start, preserving any on-disk data in its upgraded state.
This change also adds a command-line tool to overwrite the node metadata file
without performing any version checks, to unsafely bypass these checks and
recover the historical and lenient behaviour.
Secure settings currently error if they exist inside elasticsearch.yml.
This commit adds validation that non-secure settings do not exist inside
the keystore.

The date_histogram accepts an interval which can be either a calendar
interval (DST-aware, leap seconds, arbitrary length of months, etc) or
fixed interval (strict multiples of SI units). Unfortunately this is inferred
by first trying to parse as a calendar interval, then falling back to fixed
if that fails.
This leads to confusing arrangement where `1d` == calendar, but
`2d` == fixed. And if you want a day of fixed time, you have to
specify `24h` (e.g. the next smallest unit). This arrangement is very
error-prone for users.
This PR adds `calendar_interval` and `fixed_interval` parameters to any
code that uses intervals (date_histogram, rollup, composite, datafeed, etc).
Calendar only accepts calendar intervals, fixed accepts any combination of
units (meaning `1d` can be used to specify `24h` in fixed time), and both
are mutually exclusive.
The old interval behavior is deprecated and will throw a deprecation warning.
It is also mutually exclusive with the two new parameters. In the future the
old dual-purpose interval will be removed.
The change applies to both REST and java clients.
If `keyedFilters` is null it assumes there are unkeyed filters...which
will NPE if the unkeyed filters was actually empty.
This refactors to simplify the filter assignment a bit, adds an empty
check and tidies up some formatting.
This commit fixes a test bug that ends up comparing the result of two consecutive calls to System.currentTimeMillis that can be different
on slow CIs.
Closes#42064
This test can create and shuffle 2*(3*5*7) = 210 shards which is quite
heavy for our CI. This commit reduces the load, so we don't timeout on
CI.

Adds an initial limited implementations of geo features to SQL. This implementation is based on the [OpenGIS® Implementation Standard for Geographic information - Simple feature access](http://www.opengeospatial.org/standards/sfs), which is the current standard for GIS system implementation. This effort is concentrate on SQL option AKA ISO 19125-2.
Queries that are supported as a result of this initial implementation
Metadata commands
- `DESCRIBE table` - returns the correct column types `GEOMETRY` for geo shapes and geo points.
- `SHOW FUNCTIONS` - returns a list that includes supported `ST_` functions
- `SYS TYPES` and `SYS COLUMNS` display correct types `GEO_SHAPE` and `GEO_POINT` for geo shapes and geo points accordingly.
Returning geoshapes and geopoints from elasticsearch
- `SELECT geom FROM table` - returns the geoshapes and geo_points as libs/geo objects in JDBC or as WKT strings in console.
- `SELECT ST_AsWKT(geom) FROM table;` and `SELECT ST_AsText(geom) FROM table;`- returns the geoshapes ang geopoints in their WKT representation;
Using geopoints to elasticsearch
- The following functions will be supported for geopoints in queries, sorting and aggregations: `ST_GeomFromText`, `ST_X`, `ST_Y`, `ST_Z`, `ST_GeometryType`, and `ST_Distance`. In most cases when used in queries, sorting and aggregations, these function are translated into script. These functions can be used in the SELECT clause for both geopoints and geoshapes.
- `SELECT * FROM table WHERE ST_Distance(ST_GeomFromText(POINT(1 2), point) < 10;` - returns all records for which `point` is located within 10m from the `POINT(1 2)`. In this case the WHERE clause is translated into a range query.
Limitations:
Geoshapes cannot be used in queries, sorting and aggregations as part of this initial effort. In order to fully take advantage of geoshapes we would need to have access to geoshape doc values, which is coming in #37206. `ST_Z` cannot be used on geopoints in queries, sorting and aggregations since we don't store altitude in geo_point doc values.

This change updates tests that use a CountDownLatch to synchronize the
running of threads when testing concurrent operations so that we ensure
the thread has been fully created and run by the scheduler. Previously,
these tests used a latch with a value of 1 and the test thread counted
down while the threads performing concurrent operations just waited.
This change updates the value of the latch to be 1 + the number of
threads. Each thread counts down and then waits. This means that each
thread has been constructed and has started running. All threads will
have a common start point now.
Today we do not expose the cluster UUID in any logs by default, but it would be
useful to see it. For instance if a user starts multiple nodes as separate
clusters then they will silently remain as separate clusters even if they are
subsequently reconfigured to look like a single cluster. This change logs the
committed cluster UUID the first time the node encounters it.
* Switch to using a list instead of a Set for the filters, so that the
order of these filters is kept.

If remote recovery copies an index commit which has gaps in sequence
numbers to a follower; then these assertions (introduced in #40823)
don't hold for follower replicas.
Closes#41037
Currently IndexAnalyzers keeps the three default as separate class members
although they should refer to the same analyzers held in the additional
analyzers map under the default names. This assumption should be made more
explicit by keeping all analyzers in the map. This change adapts the constructor
to check all the default entries are there and the getters to reach into the map
with the default names when needed.
The changes in #39317 brought to light some concurrency issues in the
close method of Recyclers as we do not wait for threads running in the
threadpool to be finished prior to the closing of the PageCacheRecycler
and the Recyclers that are used internally. #41695 was opened to
address the concurrent close issues but upon review, the closing of
these classes is not really needed as the instances should be become
available for garbage collection once there is no longer a reference to
the closed node.
Closes#41683
We have a number of places in analysis-handling code where we check
if a field type is a keyword field, and if so then extract the normalizer rather
than pulling the index-time analyzer. However, a keyword normalizer is
really just a special case of an analyzer, so we should be able to simplify this
by setting the normalizer as the index-time analyzer at construction time.
* This test was resulting in a `PARTIAL` instead of a `SUCCESS` state for
the case of closing an index during snapshotting on 7.x
* The reason for this is the changed default behaviour regarding
waiting for active shards between 8.0 and 7.x
* Fixed by adjusting the waiting behaviour on the close index request
in the test
* Closes#39828
* When close becomes true while the management pool is shut down, we run
into an unhandled `EsRejectedExecutionException` that fails tests
* Found this while trying to reproduce #32506
* Running the IndexStatsIT in a loop is a way of reproducing this
Previously, TransportSingleShardAction required constructing a new
empty response object. This response object's Streamable readFrom
was used. As part of the migration to Writeable, the interface here
was updated to leverage Writeable.Reader.
relates to #34389.
The close method in Node uses a StopWatch to time to closing of
various services. However, the call to log the timing was made before
any of the services had been closed and therefore no timing would be
printed out. This change moves the timing log call to be a closeable
that is the last item closed.
This change makes the default seed address tests account for the lack
of an IPv6 network. By default docker containers only run with IPv4 and
these tests fail in a vanilla installation of elasticsearch-ci. To
resolve this we only expect IPv6 seed addresses if IPv6 is available.

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.

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
* 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.

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.
* 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
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.
