Currenty the rest response of the ranking evaluation API wraps all inside an
enclosing `rank_eval` object. This is redundant since it is clear from the API
call and it doesn't provide any other useful information. This change removes
this.
This commit fixes the copying of files from bundled plugin zips.
Previously all files within each zip would be flattened under the
bundled plugin name, and the original directories would exist at the top
level of the plugin.
The build-tools project (ie buildSrc) has groovy code. The -source
option was set to java 8, but this is not correct on java 9, and
actually causes a warning about not setting boot classpath. This commit
adds the --release option to groovy compilation, just like is done for
java compilation.
This commit lessens the burden on configuring settings.gradle when new
projects are added. In particular, this makes it trivial to move a
plugin to a module (or vice versa).
This commit adds a gradle plugin to ease development of meta plugins.
Applying the plugin will generated the meta plugin properties based on
the es_meta_plugin configuration object, which includes name and
description. The plugins to include within the meta plugin are
configured through the `plugins` list. An integ test task is also
automatically added.
This commit adds an extension point for client actions to action
plugins. This is useful for plugins to expose the client-side actions
without exposing the server-side implementations to the client. The
default implementation, of course, delegates to extracting the
client-side action from the server-side implementation.

The "Shorten Command Line" setting in Intellij's JUnit test configuration
was recommended to change to `classpath file`. This setting has been
causing issues with JDK9 where some modules were not being found at
runtime. This PR removes the recommendation to change this setting and
instead asks that users verify that it is set to `user-local default:none`.
This commit is related to #27260. Right now we have separate read and
write contexts for implementing specific protocol logic. However, some
protocols require a closer relationship between read and write
operations than is allowed by our current model. An example is HTTP
which might require a write if some problem with request parsing was
encountered.
Additionally, some protocols require close messages to be sent when a
channel is shutdown. This is also problematic in our current model,
where we assume that channels should simply be queued for close and
forgotten.
This commit transitions to a single ChannelContext which implements
all read, write, and close logic for protocols. It is the job of the
context to tell the selector when to close the channel. A channel can
still be manually queued for close with a selector. This is how server
channels are closed for now. And this route allows timeout mechanisms on
normal channel closes to be implemented.
MixedClusterClientYamlTestSuiteIT sometimes fails when executing the
indices.stats/13_fields/* REST tests. It does not reproduce locally
but the execution logs show that it failed when a shard is relocating
during the set up execution. This commit change the set up so that it
now waits for all shards to be active before executing the tests.
closes#26732, #27146
This logging message adds considerable noise to many REST tests, if you
are using something like HTTP basic auth in every API call or set any custom
header.
The log level moves from info to debug, so can still be seen if wanted.
This one is interesting. The third party audit task runs inside the
Gradle JVM. This means that if Gradle is started on JDK 8, the third
party audit tasks will fail as a result of the changes to support
building Elasticsearch with the JDK 9 compiler. This commit reverts the
third party audit changes to support running this task when Gradle is
started with JDK 8.
Relates #28256
This commit introduces the ability for the core Elasticsearch JAR to be
a multi-release JAR containing code that is compiled for JDK 8 and code
that is compiled for JDK 9. At runtime, a JDK 8 JVM will ignore the JDK
9 compiled classfiles, and a JDK 9 JVM will use the JDK 9 compiled
classfiles instead of the JDK 8 compiled classfiles. With this work, we
utilize the new JDK 9 API for obtaining the PID of the running JVM,
instead of relying on a hack.
For now, we want to keep IDEs on JDK 8 so when the build is in an IDE we
ignore the JDK 9 source set (as otherwise the IDE would give compilation
errors). However, with this change, running Gradle from the command-line
now requires JAVA_HOME and JAVA_9_HOME to be set. This will require
follow-up work in our CI infrastructure and our release builds to
accommodate this change.
Relates #28051
This commit modifies the build to require JDK 9 for
compilation. Henceforth, we will compile with a JDK 9 compiler targeting
JDK 8 as the class file format. Optionally, RUNTIME_JAVA_HOME can be set
as the runtime JDK used for running tests. To enable this change, we
separate the meaning of the compiler Java home versus the runtime Java
home. If the runtime Java home is not set (via RUNTIME_JAVA_HOME) then
we fallback to using JAVA_HOME as the runtime Java home. This enables:
- developers only have to set one Java home (JAVA_HOME)
- developers can set an optional Java home (RUNTIME_JAVA_HOME) to test
on the minimum supported runtime
- we can test compiling with JDK 9 running on JDK 8 and compiling with
JDK 9 running on JDK 9 in CI
Since #25826 we reject infinite values for float, double and half_float
datatypes. This change adds this restriction to the documentation for the
supported datatypes.
Closes#27653
Keeping unsafe commits when opening an engine can be problematic because
these commits are not safe at the recovering time but they can suddenly
become safe in the future. The following issues can happen if unsafe
commits are kept oninit.
1. Replica can use unsafe commit in peer-recovery. This happens when a
replica with a safe commit c1 (max_seqno=1) and an unsafe commit c2
(max_seqno=2) recovers from a primary with c1(max_seqno=1). If a new
document (seqno=2) is added without flushing, the global checkpoint is
advanced to 2; and the replica recovers again, it will use the unsafe
commit c2 (max_seqno=2 <= gcp=2) as the starting commit for sequenced
based recovery even the commit c2 contains a stale operation and the
document (with seqno=2) will not be replicated to the replica.
2. Min translog gen for recovery can go backwards in peer-recovery. This
happens when a replica with a safe commit c1 (local_checkpoint=1,
recovery_translog_gen=1) and an unsafe commit c2 (local_checkpoint=2,
recovery_translog_gen=2). The replica recovers from a primary, and keeps
c2 as the last commit, then sets last_translog_gen to 2. Flushing a new
commit on the replica will cause exception as the new last commit c3
will have recovery_translog_gen=1. The recovery translog generation of a
commit is calculated based on the current local checkpoint. The local
checkpoint of c3 is 1 while the local checkpoint of c2 is 2.
3. Commit without translog can be used for recovery. An old index, which
was created before multiple-commits is introduced (v6.2), may not have a
safe commit. If that index has a snapshotted commit without translog and
an unsafe commit, the policy can consider the snapshotted commit as a
safe commit for recovery even the commit does not have translog.
These issues can be avoided if the combined deletion policy keeps only
the starting commit onInit.

The Java API documentation for index administration currenty is wrong because
the PutMappingRequestBuilder#setSource(Object... source) and
CreateIndexRequestBuilder#addMapping(String type, Object... source) methods
delegate to methods that check that the input arguments are valid key/value
pairs:
https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-admin-indices.html
This changes the docs so the java api code examples are included from
documentation integration tests so we detect compile and runtime issues earlier.
Closes#28131
This method has a different contract than all the other methods in this class, returning null instead of an empty array when receiving a null input. While switching over some methods from delimitedListToStringArray to this method tokenizeToStringArray, this resulted in unexpected nulls in some places of our code.

This commit adds a PainlessExtension which may be plugged in via SPI to
add additional classes, methods and members to the painless whitelist on
a per context basis. An example plugin adding and using a whitelist is
also added.
This commit changes the phonetic filter factory to use a DaitchMokotoffSoundexFilter
instead of a PhoneticFilter with a daitch_mokotoff encoder when daitch_mokotoff is selected.
The latter does not hanlde branching when computing the soundex and fails to encode multiple
variations when possible.
Closes#28211
Currently we test all maps, arrays or iterables. However, in the case that maps
contain sub maps for instance, we will test the sub maps again even though the
work has already been done for the top-level map.
Relates #26907
Currently if the Lucene version is `X.Y.Z-snapshot-{gitrev}`, then we will
expect the docs to have `X.Y.Z-snapshot` as a Lucene version. I would like
to change it to `X.Y.Z` so that this doesn't need changing when we move from a
snapshot to a final release.
A bug introduced in #24407 currently prevents `eager_global_ordinals` from
being updated. This new approach should fix the issue while still allowing
mapping updates to not specify the `_parent` field if it doesn't need
updating, which was the goal of #24407.
The composite aggregation defers the collection of sub-aggregations to a second pass that visits documents only if they
appear in the top buckets. Though the scorer for sub-aggregations is not set on this second pass and generates an NPE if any sub-aggregation
tries to access the score. This change creates a scorer for the second pass and makes sure that sub-aggs can use it safely to check the score of
the collected documents.
The method `initiateChannel` on `TcpTransport` is explicit in that
channels can be connect asynchronously. All production implementations
do connect asynchronously. Only the blocking `MockTcpTransport`
connects in a synchronous manner. This avoids testing some of the
blocking code in `TcpTransport` that waits on connections to complete.
Additionally, it requires a more extensive method signature than
required for other transports.
This commit modifies the `MockTcpTransport` to make these connections
asynchronously on a different thread. Additionally, it simplifies that
`initiateChannel` method signature.
* Fix synonym phrase query expansion for cross_fields parsing
The `cross_fields` mode for query parser ignores phrase query generated by multi-word synonyms.
In such case only the first field of each analyzer group is kept. This change fixes this issue
by expanding the phrase query for each analyzer group to **all** fields using a disjunction max query.
This is related to #27933. It introduces a jar named elasticsearch-core
in the lib directory. This commit moves the JarHell class from server to
elasticsearch-core. Additionally, PathUtils and some of Loggers are
moved as JarHell depends on them.
* Adds metadata to rewritten aggregations
Previous to this change, if any filters in the filters aggregation were rewritten, the rewritten version of the FiltersAggregationBuilder would not contain the metadata form the original. This is because `AbstractAggregationBuilder.getMetadata()` returns an empty map when not metadata is set.
Closes#28170
* Always set metadata when rewritten
