This commit restores the handling of tiebreaker for multi_match
cross fields query. This functionality was lost during a refactoring
of the multi_match query (#25115).
Fixes#28933
With this commit we reduce heap usage of the ingest-geoip plugin by
memory-mapping the database files. Previously, we have stored these
files gzip-compressed but this has resulted that data are loaded on the
heap.
Closes#28782
With this commit we configure our microbenchmarks project to use the
configured RUNTIME_JAVA_HOME and to fallback on JAVA_HOME so this
behavior is consistent with the rest of the Elasticsearch build.
Closes#28961
This commit makes the controller spawner also look under modules. It
also fixes a bug in module security policy loading where the module is a
meta plugin.
Today we check for a few cases where we should maybe die before failing
the engine (e.g., when a merge fails). However, there are still other
cases where a fatal error can be hidden from us (for example, a failed
index writer commit). This commit modifies the mechanism for failing the
engine to always check for a fatal error before failing the engine.
Today when requesting _all we return all nodes regardless of what other
node qualifiers are in the request. This is contrary to how the
remainder of the API behaves which acts as additive and subtractive
based on the qualifiers and their ordering. It is also contrary to how
the wildcard * behaves. This commit removes the special handling for
_all so that it behaves identical to the wildcard *.

* Remove Booleans use from XContent and ToXContent
This removes the use of the `common.Boolean` class from two of the XContent
classes, so they can be decoupled from the ES code as much as possible.
Related to #28754, #28504
Attempting to run the REST tests, I noticed the testing instructions
in the `TESTING.asciidoc` were outdated, so I fixed the paths.
Steps I took to test:
* Ran `./gradlew :distribution:packages:rpm:assemble` and make sure
RPM is created in `./distribution/packages/rpm/build/distributions/`
* Ran testing commands and verified the REST tests ran.
Today, failures from the primary-replica resync are ignored as the best
effort to not mark shards as stale during the cluster restart. However
this can be problematic if replicas failed to execute resync operations
but just fine in the subsequent write operations. When this happens,
replica will miss some operations from the new primary. There are some
implications if the local checkpoint on replica can't advance because of
the missing operations.
1. The global checkpoint won't advance - this causes both primary and
replicas keep many index commits
2. Engine on replica won't flush periodically because uncommitted stats
is calculated based on the local checkpoint
3. Replica can use a large number of bitsets to keep track operations seqno
However we can prevent this issue but still reserve the best-effort by
failing replicas which fail to execute resync operations but not mark
them as stale. We have prepared to the required infrastructure in #28049
and #28054 for this change.

This commit adds a GoogleCloudStorageFixture that uses the
logic of a GoogleCloudStorageTestServer (added in #28576)
to emulate a remote Google Cloud Storage service.
By adding this fixture and a more complete integration test, we
should be able to catch more bugs when upgrading the client library.
The fixture is started by the googleCloudStorageFixture task
and a custom Service Account file is created and added to the
Elasticsearch keystore for each test.
This change replaces the use of string concatenation with a call to
String.join(). String concatenation might be quadratic, unless the compiler can
optimise it away, whereas String.join() is more reliably linear. There can
sometimes be a large number of pending ClusterState update tasks and #28920
includes a report that this operation sometimes takes a long time.
At one point, modules and plugins were very different. But effectively
now they are the same, just from different directories. This commit
unifies the loading methods so they are simply two different
directories. Note that the main codepath to load plugin bundles had
duplication (was not calling getPluginBundles) since previous
refactorings to add meta plugins. Note this change also rewords the
primary exception message when a plugin descriptor is missing, as the
wording asking if the plugin was built before 2.0 isn't really
applicable anymore (it is highly unlikely someone tries to install a 1.x
plugin on any modern version).
Before the `matchAllDocs` was ignored and this could lead to percolator queries not matching when
the inner query was a match_all query and min_score was specified.
Before when `verified` was not taken into account if the function_score query wrapped an unverified query this could
lead to matching percolator queries that shouldn't match at all.
This commit removes running rest tests on the full zip and tar
distributions in favor of doing a simple extraction check like is done
for rpm and deb files. The rest tests are still run on the integ test
zip, at least for now (this should eventually be moved out to a different
location).
This allows us to remove another dependency in the decoupling of the XContent
code. Rather than move this class over or decouple it, it can simply be removed.

These classes are used only in two places, and can be replaced by the
`CharArrayReader` and `CharArrayWriter`. The JDK can also perform lock biasing
and elision as well as escape analysis to optimize away non-contended locks,
rendering their lock-free implementations unnecessary.
Ingest has been failing to apply existing pipelines from cluster-state
into the in-memory representation that are no longer valid. One example of
this is a pipeline with a script processor. If a cluster starts up with scripting
disabled, these pipelines will not be loaded. Even though GETing a pipeline worked,
indexing operations claimed that this pipeline did not exist. This is because one
gets information from cluster-state and the other is from an in-memory data-structure.
Now, two things happen
1. suppress the exceptions until after other successful pipelines are loaded
2. replace failed pipelines with a placeholder pipeline
If the pipeline execution service encounters the stubbed pipeline, it is known that
something went wrong at the time of pipeline creation and an exception was thrown to
the user at some point at start-up.
closes#28269.
Running any randomized testing task within Elasticsearch currently fails
if a project has zero tests. This was supposed to be overrideable, but
it was always set to 'fail', and the system property to override was
passed down to the test runner, but never read there. This commit
changes the value of the ifNoTests setting to randomized runner to be
read from system properties and continue to default to 'fail'.
This switches the underlying byte output representation used by default in
`XContentBuilder` from `BytesStreamOutput` to a `ByteArrayOutputStream` (an
`OutputStream` can still be specified manually)
This is groundwork to allow us to decouple `XContent*` from the rest of the ES
core code so that it may be factored into a separate jar.
Since `BytesStreamOutput` was not using the recycling instance of `BigArrays`,
this should not affect the circuit breaking capabilities elsewhere in the
system.

* Factor UnknownNamedObjectException into its own class
This moves the inner class `UnknownNamedObjectException` from
`NamedXContentRegistry` into a top-level class. This is so that
`NamedXContentRegistry` doesn't have to depend on StreamInput and StreamOutput.

This is related to #27260. The transport-nio plugin needs socket
permissions to operate as a transport. This commit gives it these
permissions in the policy file.
fixed bugs that were exposed by this:
* Duplicates query leafs were not detected in a multi level boolean query
* Tracking fields for numeric range queries did not work properly.
* The sorting that was used to find the less restrictive clauses in
disjunction query did not work too.
This reverts commit f057fc294a.

This commit fixes the test progress logging to not produce an NPE when
there are no tests run. The onQuit method is always called, but onStart
would not be called if no tests match the test patterns.
This removes the readFrom and writeTo methods from XContentType, instead using
the more generic `readEnum` and `writeEnum` methods. Luckily they are both
encoded exactly the same way, so there is no compatibility layer needed for
backwards compatibility.

* Remove BytesRef usage from XContentParser and its subclasses
This removes all the BytesRef usage from XContentParser in favor of directly

immediately wraped in a BytesRef).

* Wrap stream passed to createParser in try-with-resources
This wraps the stream (`.streamInput()`) that is passed to many of the
`createParser` instances in the enclosing (or a new) try-with-resources block.
This ensures the `BytesReference.streamInput()` is closed.
Relates to #28504
* Use try-with-resources instead of closing in a finally block
This change ensures that we ignore terms removed from the analysis rather than returning a match_no_docs query for the part
that contain the stop word. For instance a query like "the AND fox" should ignore "the" if it is considered as a stop word instead of
adding a match_no_docs query.
This change also fixes the analysis of prefix terms that start with a stop word (e.g. `the*`). In such case if `analyze_wildcard` is true and `the`
is considered as a stop word this part of the query is rewritten into a match_no_docs query. Since it's a prefix query this change forces the prefix query
on `the` even if it is removed from the analysis.

Pruning tombstones is quite expensive since we have to walk though all
deletes in the live version map and acquire a lock on every value even though
it's impossible to prune it. This change does a pre-check if a delete is old enough
and if not it skips acquireing the lock.
Increase the default limit of `index.highlight.max_analyzed_offset` to 1M instead of previous 10K.
Enhance an error message when offset increased to include field name, index name and doc_id.
