Since #55785, exists queries rewrite to MatchNoneQueryBuilder when the field is unmapped.
This change also introduced a bug in the `query_string` query, using an unmapped field
like `_exists_:foo` throws an exception if the field is unmapped. This commit avoids the
exception if the query is built outside of an `ExistsQueryBuilder`.
Closes#58737
Currently we are leaving the settings to default port range in the nio
and netty4 http server test. This has recently led to tests failing due
to what appears to be a port conflict with other processes. This commit
modifies these tests to use the test case helper method to generate port
ranges.
Fixes#58433 and #58296.
An old translog header does not have a checksum. If we flip the header
version of an empty translog to the older version, then we won't detect
that corruption, and translog will be considered clean as before.
Closes#58671
A regression in the mapping code led to geo_shape no longer supporting
array-valued fields. This commit fixes this support and adds an integration
test to make sure this problem does not return!
Ingest script processors were changed to eagerly compile their scripts
when the ingest pipeline is saved, but conditional scripts were missed.
This commit adds eager compilation to ingest conditional scripts, which
will help surface errors before runtime, as well as adds tests for each
case we might encounter between inline and stored script compilation
failures.
closes#58864
We already had code to ensure the config index mappings were
up-to-date before creating a new config. However, it's also
possible that an update to a config could add the latest
settings that require the latest mappings to index correctly.
This change checks that the latest config index mappings are
in place in the 3 update actions in the same way as the checks
are done in the 3 put actions.
Backport of #58916
This commit adds an integration test that component templates used to form a composite template can
still be updated after a cluster restart.
In #58643 an issue arose where mappings were causing problems because of the way we unwrap `_doc` in
template mappings. This was also related to the mappings being merged manually rather than using the
`MapperService` to do the merging. #58643 was fixed in 7.9 and master with the #58521 change, since
mappings now are read and digested by the actual mapper service.
This test passes for 7.x and master, and I intend to open a separate PR including this test for
7.8.1 along with a bug fix for #58643. This test is to ensure we don't have any regression in the
future.
The refactoring in #57666 inadvertently enabled norms on two of the percolator subfields,
leading to an increase in memory usage. This commit disables norms on these fields again.
Refactor sequence matching classes in order to decouple querying from
results consumption (and matching).
Rename some classes to better convey their intent.
Introduce internal pagination of sequence algorithm, that is getting the
data in slices and, if needed, moving forward in order to find more
matches until either the dataset is consumer or the number of results
desired is found.

Add caching support for application privileges to reduce number of round-trips to security index when building application privilege descriptors.
Privilege retrieving in NativePrivilegeStore is changed to always fetching all privilege documents for a given application. The caching is applied to all places including "get privilege", "has privileges" APIs and CompositeRolesStore (for authentication).
The `date_histogram` aggregation had an optimization where it'd rewrite
`time_zones` who's offset from UTC is fixed across the entire index.
This rewrite is no longer needed after #56371 because we can tell that a
time zone is fixed lower down in the aggregation. So this removes it.
* [ML] handles compressed model stream from native process (#58009)
This moves model storage from handling the fully parsed JSON string to handling two separate types of documents.
1. ModelSizeInfo which contains model size information
2. TrainedModelDefinitionChunk which contains a particular chunk of the compressed model definition string.
`model_size_info` is assumed to be handled first. This will generate the model_id and store the initial trained model config object. Then each chunk is assumed to be in correct order for concatenating the chunks to get a compressed definition.
Native side change: https://github.com/elastic/ml-cpp/pull/1349
When the documents are large, a follower can receive a partial response
because the requesting range of operations is capped by
max_read_request_size instead of max_read_request_operation_count. In
this case, the follower will continue reading the subsequent ranges
without checking the remaining size of the buffer. The buffer then can
use more memory than max_write_buffer_size and even causes OOM.
Backport of #58620
Since #58728 part of searchable snapshot shard files are written in cache
in an asynchronous manner in a dedicated thread pool. It means that even
if a search query is successful and returns, there are still more bytes to
write in the cached files on disk.
On CI this can be slow; if we want to check that the cached_bytes_written
has changed we need to check multiple times to give some time for the
cached data to be effectively written.
