Lucene has a new `FeatureField` which gives the ability to record numeric
features as term frequencies. Its main benefit is that it allows to boost
queries with the values of these features and efficiently skip non-competitive
documents at the same time using block-max WAND and indexed impacts.
This is related to #29500. We are removing the ability to disable http
pipelining. This PR removes the references to disabling pipelining in
the integration test case.
A rolling upgrade from oss Elasticsearch to the default distribution of
Elasticsearch is significantly different than a full cluster restart to
install a plugin and is again different from starting a new cluster with
xpack installed. So this adds some basic tests to make sure that the
rolling upgrade that enables xpack works at all.
This also removes some unused imports from the tests that I modified in
PR #30728. I didn't mean to leave them.
The VerifyRepositoryResponse class holds a DiscoveryNode[], but the
nodes themselves are not serialized to a REST API consumer. Since we do
not want to put all of a DiscoveryNode over the wire, be it REST or
Transport since its unused, this change introduces a BWC compatible
change in ser/deser of the Response. Anything 6.4 and above will
read/write a NodeView, and anything prior will read/write a
DiscoveryNode. Further changes to 7.0 will be introduced to remove the
BWC shim and only read/write NodeView, and hold a List<NodeView> as the
VerifyRepositoryResponse internal state.
This commit reduces the Windows CLI scripts to one-liners by moving all
of the redundant logic to an elasticsearch-cli script. This commit is
only the Windows side, a previous commit covered the Linux side.
This is code that was leftover from the move to one shard by
default. Here in index metadata we were preserving the default number of
shards settings independently of the area of code where we set this
value on an index that does not explicitly have an number of shards
setting. This took into consideration the es.index.max_number_of_shards
system property, and was used in search requests to set the default
maximum number of concurrent shard requests. We set the default there
based on the default number of shards so that in a one-node case a
search request could concurrently hit all shards on an index with the
defaults. Now that we default to one shard, we expect fewer shards in
clusters and this adjustment of the node count as the max number of
concurrent shard requests is no longer needed. This commit then changes
the default number of shards settings to be consistent with the value
used when an index is created, and removes the now unneeded adjustment
in search requests.
Adding headers rather than setting them all at once seems more
user-friendly and we already do it in a similar way for parameters
(see Request#addParameter).
This commit adds a max wait timeout of one second to all the latch.await
calls made in RestClientTests. It also makes clearer that the `onSuccess`
listener method will never be called given that the underlying http
client is mocked and makes sure that `latch.countDown` is always called
Currently the first snippet in the documentation test in script-fields.asciidoc
isn't executed, although it has the CONSOLE annotation. Adding a test setup
annotation to it seems to fix the problem.
The new snapshot includes LUCENE-8324 which fixes missing checkpoint
after a fully deletes segment is dropped on flush. This snapshot should
resolves failed tests in the CorruptedFileIT suite.

This is related to #29500 and #28898. This commit removes the abilitiy
to disable http pipelining. After this commit, any elasticsearch node
will support pipelined requests from a client. Additionally, it extracts
some of the http pipelining work to the server module. This extracted
work is used to implement pipelining for the nio plugin.
=== Char Group Tokenizer
The `char_group` tokenizer breaks text into terms whenever it encounters
a
character which is in a defined set. It is mostly useful for cases where
a simple
custom tokenization is desired, and the overhead of use of the
<<analysis-pattern-tokenizer, `pattern` tokenizer>>
is not acceptable.
=== Configuration
The `char_group` tokenizer accepts one parameter:
`tokenize_on_chars`::
A string containing a list of characters to tokenize the string on.
Whenever a character
from this list is encountered, a new token is started. Also supports
escaped values like `\\n` and `\\f`,
and in addition `\\s` to represent whitespace, `\\d` to represent
digits and `\\w` to represent letters.
Defaults to an empty list.
=== Example output
```The 2 QUICK Brown-Foxes jumped over the lazy dog's bone for $2```
When the configuration `\\s-:<>` is used for `tokenize_on_chars`, the
above sentence would produce the following terms:
```[ The, 2, QUICK, Brown, Foxes, jumped, over, the, lazy, dog's, bone,
for, $2 ]```
This commit changes the wait for a few netty threads to wait for these
threads to complete after the cluster has stopped. Previously, we were
waiting for these threads before the cluster was actually stopped; the
cluster is stopped in an AfterClass method of ESIntegTestCase, while
the wait was performed in the AfterClass of a class that extended
ESIntegTestCase, which is always executed before the AfterClass of
ESIntegTestCase.
Now, the wait is contained in an ExternalResource ClassRule that
implements the waiting for the threads to terminate in the after
method. This rule is executed after the AfterClass method in
ESIntegTestCase. The same fix has also been applied in
SecuritySingleNodeTestCase.
Closes#30563
We added this limit because we occasionally saw cases where most of the memory
usage of the cache was spent on the keys (ie. queries) rather than the values,
which caused the cache to vastly underestimate its memory usage. In recent
releases, we disabled caching on heavy `terms` queries, which were the main
source of the problem, so putting more entries in the cache should be safer.
Prior to this change an json array element with no fields would be omitted from json array.
Nested inner hits source filtering relies on the fact that the json array element numbering
remains untouched and this causes AOOB exceptions in the ES side during the fetch phase
without this change.
Closes#30624
The test has an issue that exhibits only super rarely. The test sets the publish
timeout to 0, then proceeds to block cluster state processing on a data node,
then deletes an index and recreates it, and finally removes the cluster state
processing block. Finally, it calls ensureGreen, which might now return before
the data node has fully applied the cluster state that removed and readded the
shard, due to the publish timeout of 0. This commit waits for the cluster state
to be fully processed on the data node before doing the search.
Closes#30718
This change makes sure that an empty completion input does not throw an IAE when indexing.
Instead the input is ignored and the completion field is added in the list of ignored fields
for the document.
Closes#23121
This commit fixes docs failure on language analyzers when compared to the built in analyzers.
The `elision` filters used by the rebuilt language analyzers should be case insensitive to match
the definition of the prebuilt analyzers.
Closes#30557
We post snapshot builds to snapshots.elastic.co yet the official plugin
installer will not let you install such plugins without manually
downloading them and installing them from a file URL. This commit adds
the ability for the plugin installer to use snapshots.elastic.co for
installing official plugins if a es.plugins.staging is set and the
current build is also a snapshot build. Otherwise, we continue to use
staging.elastic.co if the current build is a release build and
es.plugins.staging is set and, of course, use the release artifacts at
artifacts.elastic.co for release builds with es.plugins.staging unset.

This is related to #27260. The elasticsearch-nio jar is supposed to be
a library opposed to a framework. Currently it internally logs certain
exceptions. This commit modifies it to not rely on logging. Instead
exception handlers are passed by the applications that use the jar.
This commit adds Delete Repository, the associated docs and tests for
the high level REST API client. It also cleans up a seemingly innocuous
line in the RestDeleteRepositoryAction and some naming in SnapshotIT.

This commit reduces the Linux CLI scripts to one-liners by moving all of
the redundant logic to an elasticsearch-cli script. This commit is only
the Linux side, a follow-up will do this for Windows too.
Make all bool constructs use match/should (that is a query context) as
that is controlled and changed to a filter context by ES automatically
based on the sort order (_doc, field vs _sort) and trackScores.
Fix#29685
Switches the rolling upgrade tests from upgrading two nodes to upgrading
three nodes which is much more realistic and much better able to find
unexpected bugs. It upgrades the nodes one at a time and runs tests
between each upgrade. As such this now has four test runs:
1. Old
2. One third upgraded
3. Two thirds upgraded
4. Upgraded
It sets system properties so the tests can figure out which stage they
are in. It reuses the same yml tests for the "one third" and "two
thirds" cases because they are *almost* the same case.
This rewrites the yml-based indexing tests to be Java based because the
yml-based tests can't handle different expected values for the counts.
And the indexing tests need that when they are run twice.
This change is to support rolling upgrade from a pre-6.3 default
distribution (i.e. without X-Pack) to a 6.3+ default distribution
(i.e. with X-Pack).
The ML metadata is no longer eagerly added to the cluster state
as soon as the master node has X-Pack available. Instead, it
is added when the first ML job is created.
As a result all methods that get the ML metadata need to be able
to handle the situation where there is no ML metadata in the
current cluster state. They do this by behaving as though an
empty ML metadata was present. This logic is encapsulated by
always asking for the current ML metadata using a static method
on the MlMetadata class.

The copy_settings parameter will be removed in Elasticsearch 8.0.0. This
commit adds an assertion message that to clean up this code when master
is bumped to 8.0.0.
* disable annotation processor for docs
Could not find evidence that the log4j annotation processor is used.
The compiler flag enables the Gradle 5.0 behavior
Closes#30476
* Disable annotation processors for all tests
* remove redundant `-proc:none` already handled by required plugins
* Revert unintentional changes
Added dedicated script contexts for:
* script function score
* script sorting
* terms_set query
Scripts for these contexts will either have a specific return value or
use scoring and therefor in the future will need their own scripting classes.
Relates to #30511
The getDate() and getDates() existed prior to 5.x on long fields in
scripting. In 5.x, a new Date type for ScriptDocValues was added. The
getDate() and getDates() methods were left on long fields and added to date
fields to ease the transition. This commit removes those methods for
7.0.
The docs/README shows how to run the :docs:check goal on a subset of pages,
however using the current example fails. Removing the masking character before
the first wildcard fixes the problem.
