The new discovery stats were pushed to the 6.x branch (currently
versioned at 6.1.0) but master was not updated to reflect this. This
impacts the mixed-cluster BWC tests because a 6.1.0 node will be trying
to send a 7.0.0 node the new discovery stats but the 7.0.0 did not yet
understand that it should be reading these when talking to a 6.1.0
node. This commit addresses this, and changes the skip version on the
discovery stats REST tests.
It's believed that using diffs obsoletes the other mechanism for reusing the
bits of the ClusterState that didn't change between updates, but in fact we
don't know for sure how often the diff mechanism works successfully. The stats
collected here will tell us.
The shard preference _primary, _replica and its variants were useful
for the asynchronous replication. However, with the current impl, they
are no longer useful and should be removed.
Closes#26335
This test has been failing in th Ruby runner, since it assumed the `headers` feature,
but was not annotated accordingly.
This patch adds the `skip` clause with the `headers` feature.
Closes#26896
Early termination with index sorting always return the best top N in the response but set the flag `terminated_early`
in the response. This can be confusing because we use the same flag for `terminate_after` which on the contrary returns partial results.
This change removes the flag when results are not partial (early termination due to index sorting) and keeps it only when `terminate_after` is used.
Closes#26408
Adds the wait_for_active_shards parameter to the index open command. Similar to the index creation command, the index open command will now, by default, wait until the primaries have been allocated.
Closes#20937
This commit adds a skip for the bad request REST test on pre-6.0
nodes. Previously, a request for /_(.*) where $1 is not an existing
endpoint would return a 404. This is because the request would be
treated as a get index request for an index named _$1. However, an index
can never start with "_" so logic was added to detect this and return a
400 instead as this should be treated as a bad request. During the
mixed-cluster BWC tests, a node running pre-6.0 code will still return a
404 though. Therefore, this test needs to skipped in such a
mixed-cluster scenario.
This commit adds validation to the resolving of indexes in the wildcard
expression resolver. It no longer throws a 404 Not Found when resolving
invalid indices. It throws a 400 instead, as it is an invalid
index. This was the behavior of 5.x.
After backporting the script_field soft limit to the 6.x branches, this test can
now also run in a mixed cluster.

Today we have all non-plugin mappers in core. I'd like to start moving those
that neither map to json datatypes nor are very frequently used like `date` or
`ip` to a module.
This commit creates a new module called `mappers-extra` and moves the
`scaled_float` and `token_count` mappers to it. I'd like to eventually move
`range` fields there but it's more complicated due to their intimate
relationship with range queries.

Requesting to many script_fields in a search request can be costly
because of script execution. This change introduces a soft limit on the number
of script fields that are allowed per request. The setting can be
changed per index using the index.max_script_fields setting.
Relates to #26390
Requesting to many docvalue_fields in a search request can potentially be costly
because it might incur a per-field per-document seek. This change introduces a
soft limit on the number of fields that can be retrieved. The setting can be
changed per index using the `index.max_docvalue_fields_search` setting.

This change exposes the duplicate removal option added in Lucene for the completion suggester
with a new option called `skip_duplicates` (defaults to false).
This commit also adapts the custom suggest collector to handle deduplication when multiple contexts match the input.
Closes#23364
This change adds a dynamic cluster setting named `search.max_keep_alive`.
It is used as an upper limit for scroll expiry time in scroll queries and defaults to 1 hour.
This change also ensures that the existing setting `search.default_keep_alive` is always smaller than `search.max_keep_alive`.

* check style
* add skip for bwc
* iter
* Add a maxium throttle wait time of 1h for reindex
* review
* remove empty line
The `from` search parameter cannot really be used in scrolled searches. This
commit adds a check for this case to the SearchRequest#validate() method so we
can reported it as an error rather than silently ignoring it.
Closes#9373
* Add REST tests for value_count, stats, extended_stats and cardinality aggs
Also updates the document type of of other agg REST tests to `doc`

Due to the weird way of structuring the serialization code in AcknowledgedRequest, many request types forgot to properly serialize the request timeout, for example "index deletion", "index rollover", "index shrink", "putting pipeline", and other requests. This means that if those requests were not directly sent to the master node, the acknowledgement timeout information would be lost (and the default used instead).
Some requests also don't properly expose the timeout mechanism in the REST layer, such as put / delete stored script. This commit fixes all that.
Raw requests are supported only by the java yaml test runner and were introduced to test docs snippets. Some yaml tests ended up using them (see #23497) which causes failures for other language clients. This commit migrates those yaml tests to Java tests that send requests through the Java low-level REST client, and also moves the ability to send raw requests to a special client that's only available when testing docs snippets.
Closes#25694
When `refresh=wait_for` is set on an indexing request, we register a listener on the shards that are call during the next refresh. During the recover translog phase, when the engine is open, we have a window of time when indexing operations succeed and they can add their listeners. Those listeners will only be called when the recovery finishes as we do not refresh during recoveries (unless the indexing buffer is full). Next to being a bad user experience, it can also cause deadlocks with an ongoing peer recovery that may wait for those operations to mark the replica in sync (details below).
To fix this, this PR changes refresh listeners to be a noop when the shard is not yet serving reads (implicitly covering the recovery period). It doesn't matter anyway.
Deadlock with recovery:
When finalizing a peer recovery we mark the peer as "in sync". To do so we wait until the peer's local checkpoint is at least as high as the global checkpoint. If an operation with `refresh=wait_for` is added as a listener on that peer during recovery, it is not completed from the perspective of the primary. The primary than may wait for it to complete before advancing the local checkpoint for that peer. Since that peer is not considered in sync, the global checkpoint on the primary can be higher, causing a deadlock. Operation waits for recovery to finish and a refresh to happen. Recovery waits on the operation.
In the refresh REST tests we setup some persistent settings for debug
logging. In the teardown, we try to restore the logging level back to
info via another persistent setting but this is a mistake because other
tests check if there are no persistent settings. To fix this, we remove
the persistent setting that we added.
We are chasing a test failure in the "refresh=wait_for waits until
changes are visible in search" test yet the logs currently give us no
indication what is happening. This commit adds debug logging for this
test, and cleans up this logging in a teardown section. We can remove
this additional logging after we chase the test failure down.
Since the setup attempts to create an index with two types, and the setup runs before any test,
this will fail on versions 6.0+ before it has a chance to check the skip in each individual
test. Moving to the setup resolves this issue.
This change rewrites search requests on the coordinating node before
we send requests to the individual shards. This will reduce the rewrite load
and object creation for each rewrite on the executing nodes and will fetch
resources only once instead of N times once per shard for queries like `terms`
query with index lookups. (among percolator and geo-shape)

Also has updates to ScriptMetaData for allowing the old namespace format to be loaded all the way back through 5.0; however, it will throw an exception if two scripts share the same id but different languages.
With #23997 and #25268 we have changed put alias, delete alias, update aliases and delete index to not accept aliases. Instead concrete indices should be provided as their index parameter.
This commit improves the error message in case aliases are provided, from an IndexNotFoundException (404 status code) with "no such index" message, to an IllegalArgumentException (400 status code) with "The provided expression [alias] matches an alias, specify the corresponding concrete indices instead." message.
Note that there is no specific error message for the case where wildcard expressions match one or more aliases. In fact, aliases are simply ignored when expanding wildcards for such APIs. An error is thrown only when the expression ends up matching no indices at all, and allow_no_indices is set to false. In that case the error is still the generic "404 - no such index".
403 can be confused with security. If an API doesn't support working against closed indices and closed indices are referred to in a request, that is a bad request, hence 400 is more appropriate.
Currently the `to` and `from` parameter in the `date_range` aggregation is not
parsed with the correct date field format from the mappings or the aggregation
if the argument is numeric, but always treated as a long value specifying
`epoch_millis`. This leads to problems e.g. when the format is `epoch_second`,
but the `to` and `from` are currently treated as millis.
With this change, we interpret these parameters according to the `format` of the target field.
If the `format` in the mappings is not compatible with numeric input values,
a compatible `format` (e.g. `epoch_millis`, `epoch_second`) must be specified in
the `date_range` aggregation itself, otherwise an error is thrown.
#Closes #17920
This commit reverts some changes to the shrink API ignore template
mapping REST test in favor of simply skipping the test for BWC
purposes. The complexity here is due to deprecations and lacking the
infrastructure to gracefully handle a situation like this.
This change skips the rest test in `rest-api-spec/test/indices.shrink/20_source_mapping.yml` as it currently fails because if we don’t expect the deprecation warning the normal rest tests fail because they get a warning they don’t expect but if we do expect the deprecation warning the mixed cluster tests fail because they don’t get a warning which they expected.
This commit fixes an issue with the REST test that the shrink API
ignores templates. The problem is that we have to use a BWC version of
the API (for the BWC tests) but this raises deprecation warnings. This
commit adds an expectation for these deprecation warnings.
