Computing the compressed size of the cluster state on every invocation
of cluster:monitor/state action is expensive, and the value of this
field is dubious anyway. Therefore we want to remove computing this
field. As a first step, we stop computing and return this field by
default. To avoid breaking users, we will give them a system property to
use to tide them over until the next major release when we will actually
remove this field. This comes with a deprecation warning too, and the
backport to the appropriate minor will also include a note in the
migration guide. There will be a follow-up to remove this field in the
next major version.
Previously, JDBC's REST call to the server was always sending UTC
instead of the timezone passed through connection string/properties.
Moreover the conversion to java.sql.Date was problematic as a
calculation on the epoch millis was used to set the time to 00:00:00.000
and the timezone info was lost. This caused the resulting java.sql.Date
object which is always using the JVM's timezone (no matter what timezone
setting is used in the connection string/properties) to be wrongly created.

After the joda-java time migration we were formatting zone ids with zoneOrOffsetId method. This when a date was provided with a ZoneRegion for instance America/Edmonton it was appending this zone identifier instead of zone formatted as +HH:MM.
This fix is changing the format of zone suffix for all printers and also always wrapping a Temporal into a ZonedDateTime when formatting.

This breaks on windows where TMP dir default to C:\Windows and startup
fails with a permission error.
I tried to create a tmp dir and pass in `TMP` env, but it lead to a
class not found error, and since testclusers is already independent of
the calling environment I stopped there.
Currently there is a method `Recycler#obtain(size)` that allows a size
parameter to be passed. However all implementations ignore this
parameter and just allocate a page size based on other settings. This
commit removes this method.
`document_type` is the type to use for parsing the document to percolate, which
is already optional and deprecated. However `percotale` queries also have the
ability to percolate existing documents, identified by an index, an id and a
type. This change makes the latter optional and deprecated.
Closes#39963
When performing the test with 57 master-eligible nodes and one node
crash, we saw messy elections, when multiple nodes were attempting to
become master.
JoinHelper has logged 105 long log messages with lengthy stack
traces during one such election.
To address this, we decided to log these messages every time only on
debug level.
We will log last unsuccessful join attempt (along with a timestamp)
if any with WARN level if the cluster is failing to form.

The problem here was that `DatafeedJob` was updating the last end time searched
based on the `now` even though when there are aggregations, the extactor will
only search up to the floor of `now` against the histogram interval.
This commit fixes the issue by using the end time as calculated by the extractor.
It also adds an integration test that uses aggregations. This test would fail
before this fix. Unfortunately the test is slow as we need to wait for the
datafeed to work in real time.
Closes#39842
The change replaces the Vagrant box based fixture with a fixture
based on docker compose and 2 docker images, one for an openldap
server and one for a Shibboleth SAML Identity Provider.
The configuration of both openldap and shibboleth is identical to
the previous one, in order to minimize required changes in the
tests
Currently token filter settings are treated as fixed once they are declared and
used in an analyzer. This is done to prevent changes in analyzers that are already
used actively to index documents, since changes to the analysis chain could
corrupt the index. However, it would be safe to allow updates to token
filters at search time ("search_analyzer"). This change introduces a new
property of token filters that allows to mark them as only being usable at search
or at index time. Any analyzer that uses these tokenfilters inherits that property
and can be rejected if they are used in other contexts. This is a first step towards
making specific token filters (e.g. synonym filter) updateable.

When following the steps mentioned in upgrade guide
https://www.elastic.co/guide/en/elastic-stack/6.6/upgrading-elastic-stack.html
if we disable the cluster shard allocation but fail to enable it after
upgrading the nodes and plugins, the next step of upgrading internal
indices fails. As we did not check the bulk request response for reindexing,
we delete the old index assuming it has been created. This is fatal
as we cannot recover from this state.
This commit adds a pre-upgrade check to test the cluster shard
allocation setting and fail upgrade if it is disabled. In case there
are search or bulk failures then we remove the read-only block and
fail the upgrade index request.
Closes#39339
Today, when applying new cluster state we attempt to connect to all of its
nodes as a blocking part of the application process. This is the right thing to
do with new nodes, and is a no-op on any already-connected nodes, but is
questionable on known nodes from which we are currently disconnected: there is
a risk that we are partitioned from these nodes so that any attempt to connect
to them will hang until it times out. This can dramatically slow down the
application of new cluster states which hinders the recovery of the cluster
during certain kinds of partition.
If nodes are disconnected from the master then it is likely that they are to be
removed as part of a subsequent cluster state update, so there's no need to try
and reconnect to them like this. Moreover there is no need to attempt to
reconnect to disconnected nodes as part of the cluster state application
process, because we periodically try and reconnect to any disconnected nodes,
and handle their disconnectedness reasonably gracefully in the meantime.
This commit alters this behaviour to avoid reconnecting to known nodes during
cluster state application.
Resolves#29025.
The LDAP tests attempt to bind all interfaces,
but if for some reason an interface can't be bound
the tests will stall until the suite times out.
This modifies the tests to be a bit more lenient and allow
some binding to fail so long as at least one succeeds.
This allows the test to continue even in more antagonistic
environments.
This change marks the transport-nio plugin as having a client jar. The
nio transport can be used from a transport client and the
x-pack-transport artifact depends on the transport-nio jar but this jar
is not published. This change marks the transport-nio project as having
a client jar so that the jar may be published in the same way that we
publish the netty4 transport artifact.
The change to actually publish the jar will be handled separately as an
update to the release manager.
Indices with very large numbers of fields (>1024 by default) that do not
have index.query.default_field set will experience query failures in 7.0
for Simple Query String and Multi-Match queries. This deprecation check
issues a warning for indices of that size that do not have
index.query.default_field set.
This also adds a deprecation check for index templates with field counts
that would trigger these query failures as well.
This commit, mostly authored by @DaveCTurner,
adds documentation for elasticsearch-node tool #37696.

Lucene 8.0 includes a [change](https://issues.apache.org/jira/browse/LUCENE-8635)
that moves the terms index off-heap for all fields but ID fields. I'm
including this in the migration notes so that users who have queries that match
lots of terms won't be surprised in case of slowdown.
- new `rank_feature`/`script_score` queries
- new `index_phrases`/`index_prefixes` options
- disabling `_field_names` doesn't help anymore
- adaptive replica selection is on by default
We were missing release notes for 7.0.0-alpha1. I generated them by running
the release-notes script with a quick hack that filtered out pull requests
that had been closed on or after 2018-11-15.
Some breaking changes had been documented in the release notes rather than
the migration guide so I moved them.
The changes in #39732 mean that nodes in the IntegTest clusters will
now run with whichever java version is defined as `runtime.java` and
not JAVA_HOME anymore.
This means that these nodes will also run in JVM with fips approved
mode enabled and as such, need to have access to the password for the
BCFKS keystore that is used as the default keystore/truststore.
This change sets the two necessary system properties.
Resolves#39855
If a primary on 6.7 and a replica on 5.6 are running more than 5 minutes
(retention leases background sync interval), the retention leases
background sync will be triggered, and it will trip 6.7 node due to the
illegal checkpoint value. We can fix the problem by making the returned
checkpoint depends on the node version. This PR, however, chooses to
enforce retention leases require soft deletes, and make retention leases
sync noop if soft deletes is disabled instead.
Closes#39914
When a query is translated into script terms agg where key has a date
type, it should generate a terms agg with value_type long instead of
date, otherwise the key gets formatted as a string, which confuses
hit extractor.
Fixes#37042
* The test failure in #39852 is caused by a file in the initial repository when there should not be any
* It seems that on a normal consistent file system no left-over file should exist ever here after the validation finishes and I can't reproduce or see any other path to a dangling file in the fresh respository
=> added a more verbose and strict assertion that will log what file is left over next time

This commit removes the "doc" type from monitoring internal indexes.
The template still carries the "_doc" type since that is needed for
the internal representation.
This change impacts the following templates:
monitoring-alerts.json
monitoring-beats.json
monitoring-es.json
monitoring-kibana.json
monitoring-logstash.json
As part of the required changes, the system_api_version has been
bumped from "6" to "7" and support for version "2" has been dropped.
A new empty pipeline is now introduced for the version "7", and
the formerly empty "6" pipeline will now remove the type and re-direct
the request to the "7" index.
Additionally, to due to a difference in the internal representation
(which requires the inclusion of "_doc" type) and external representation
(which requires the exclusion of any type) a helper method is introduced
to help convert internal to external representation, and used by the
monitoring HTTP template exporter.
