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.

Executors of type fixed_auto_queue_size (i.e. search / search_throttled) wrap runnables into
TimedRunnable, which is an AbstractRunnable. This is dangerous as it might silently swallow
exceptions, and possibly miss calling a response listener. While this has not triggered any failures in
the tests I have run so far, it might help uncover future problems.
Follow-up to #36137
This test started failing since decreasing the leader and follower check timeouts (#38298). The
reason is that the test was relying on the default publication timeout to come into effect before
leader / follower check timeouts, which is now not always true anymore.
Closes#38867
This fixes a bug where a String to char cast in Painless could be done implicitly.
It is now required that a String to char cast is explicit as documented in the
existing specification. This also adds char and Character casting tests.
Currently we log exceptions due to channel close at the debug level in
the normal exception handler. Currently we log all send failures due to
channel close at the warn level. This commit changes that to only log at
warn if the send failure is not due to channel closed. Additionally, it
adds the ssl engine closed as a channel close exception.
Painless allows ZonedDateTime objects to be passed natively to scripts
which creates problematic translate queries as the ZonedDateTime is
passed as a string instead.
Wrap this with a dedicated method to perform the conversion.
Fix#39877
(cherry picked from commit 4957cad5bda77257d10430ac102e93f5e062148a)
Today we use a ConcurrentHashSet to track the in-flight outgoing joins in the
`JoinHelper`. This is fine for adding and removing elements but not for the
emptiness test in `isJoinPending()` which might return false if one join
finishes just after another one starts, even though joins were pending
throughout.
As used today this is ok: it means the node was trying to join a master but
this join attempt just finished unsuccessfully, and causes it to (rightfully)
reject a `FollowerCheck` from the failed master. However this kind of API
inconsistency is trappy and there is no need to be clever here, so this change
replaces the set with a `synchronizedSet()`.
Enhance ConstantProcessor to properly serialize complex objects
(Intervals) that have their own custom serialization/deserialization
mechanism
Fix#39875
(cherry picked from commit ed8a1f9340673e69a44ea7a89679cadb4762e43d)
When ESRejectedExecutionException gets thrown on the coordinating node while trying to fetch hits, the resulting exception will hold no shard failures, hence `503` is used as the response status code. In that case, `429` should be returned instead. Also, the status code should be taken from the cause if available whenever there are no shard failures instead of blindly returning `503` like we currently do.
Closes#38586
* reduce the number of leader indices to be auto followed
* also check the number of follower indices being created
* also check the whether leader indices are marked as auto followed

The monitoring bulk API accepts the same format as the bulk API, yet its concept
of types is different from "mapping types" and the deprecation warning is only
emitted as a side-effect of this API reusing the parsing logic of bulk requests.
This commit extracts the parsing logic from `_bulk` into its own class with a
new flag that allows to configure whether usage of `_type` should emit a warning
or not. Support for payloads has been removed for simplicity since they were
unused.
@jakelandis has a separate change that removes this notion of type from the
monitoring bulk API that we are considering bringing to 8.0.
This commit propagates some exceptions that were previously swallowed and also
makes sure that exceptions closing streams are either propagated if the try
block succeeded or added as suppressed exceptions otherwise.
* [ML] refactoring lazy query and agg parsing
* Clean up and addressing PR comments
* removing unnecessary try/catch block
* removing bad call to logger
* removing unused import
* fixing bwc test failure due to serialization and config migrator test
* fixing style issues
* Adjusting DafafeedUpdate class serialization
* Adding todo for refactor in v8
* Making query non-optional so it does not write a boolean byte
This commit consolidates more mapping validation logic into the same class.
`FieldTypeLookup` is now a bit simpler, and has the sole responsibility of quickly
resolving field names to their types.
I have a broader refactor planned around mapping merge validation, but this
change should at least be a step in the right direction.
These simplifications to `MapperMergeValidator` are possible now that there is
always a single mapping definition.
* Remove the type argument in `validateMapperStructure`.
* Remove unnecessary checks against existing mappers.
If TransportService is stopped before a shard-failure request is sent
but after the request is registered, TransportService will notify
ReplicationOperation a TransportException with an error message:
"transport stop, action: internal:cluster/shard/failure".
Relates #39584
the test "Implicitly create a typeless ... typed template"
fails occasionally because the index operation hasn't
propogated to update the index mapping in time for the
following assertion about a dynamically mapped field "bar".
error failed with:
```
field [test-1.mappings.my_type.properties.bar] doesn't have a true value
Expected: not null
but: was null
```
refreshing the index should resolve this timing issue.
Recently we have had a number of test issues related to blocking
activity occuring on the io thread. This commit adds a log warning for
when handling event takes a >150 milliseconds. This is implemented
for the MockNioTransport which is the transport used in
ESIntegTestCase.
The watcher stats implementation tries to look at all queued watches
before preparing the result. We want to cast these to a
WatchExecutionTask to extract the context to prepare the stats for
queued watches. The problem is that not all tasks on the watcher queue
were WatchExecutionTask. This is because a manually executed watch was
not even at all wrapped in a WatchExecutionTask. Moreover, we were using
ExecutorService#submit(Runnable) which would wrap the Runnable in a
FutureTask<?>. This commit addresses this by using a WatchExecutionTask,
and also using ExecutorService#execute(Runnable) so that no wrapping
occurs. This will let us continue with the assumption that all queued
tasks are WatchExecutionTasks.
The posix_spawn method of launching a process from Java
goes via an intermediate process called jspawnhelper
which lives in the lib directory rather than the bin
directory and hence got missed by the original chmod
loop. This change adds jspawnhelper as a special case.
It's the only program that's in the lib directory in a
macOS JDK 11.
* Bundle java in distributions
Setting up a jdk is currently a required external step when installing
elasticsearch. This is particularly problematic for the rpm/deb packages
as installing a jdk in the same package installation command does not
guarantee any order, so must be done in separate steps. Additionally,
JAVA_HOME must be set and often causes problems in selecting a correct
jdk when, for example, the system java is an older unsupported version.
This commit bundles platform specific openjdks into each distribution.
In addition to eliminating the issues above, it also presents future
possible improvements like using jlink to build jdk images only
containing modules that elasticsearch uses.

This commit removes the "doc" type from watcher internal indexes.
The template still carries the "_doc" type since that is needed for
the internal representation.
This impacts the .watches, .triggered-watches, and .watch-history indexes.
External consumers do not need any changes since all external calls
go through the _watcher API, and should not interact with the the .index directly.

This test was more complicated than necessary, where we were capturing
requests to prevent removal of retention leases, so that our forget
follower request could remove the retention leases instead. Instead, a
pause is enough to ensure that the retention leases are not re-added
after we remove them by the forget follower request. This commit
simplifies this test, and should remove some spurious failures.
