This commit removes the RequestBuilder generic type from Action. It was
needed to be used by the newRequest method, which in turn was used by
client.prepareExecute. Both of these methods are now removed, along with
the existing users of prepareExecute constructing the appropriate
builder directly.
Currently failures to compile a script usually lead to a ScriptException, which
inherits the 500 INTERNAL_SERVER_ERROR from ElasticsearchException if it does
not contain another root cause. Instead, this should be a 400 Bad Request error.
This PR changes this more generally for script compilation errors by changing
ScriptException to return 400 (bad request) as status code.
Closes#12315
This commit changes the default out-of-the-box configuration for the
number of shards from five to one. We think this will help address a
common problem of oversharding. For users with time-based indices that
need a different default, this can be managed with index templates. For
users with non-time-based indices that find they need to re-shard with
the split API in place they no longer need to resort only to
reindexing.
Since this has the impact of changing the default number of shards used
in REST tests, we want to ensure that we still have coverage for issues
that could arise from multiple shards. As such, we randomize (rarely)
the default number of shards in REST tests to two. This is managed via a
global index template. However, some tests check the templates that are
in the cluster state during the test. Since this template is randomly
there, we need a way for tests to skip adding the template used to set
the number of shards to two. For this we add the default_shards feature
skip. To avoid having to write our docs in a complicated way because
sometimes they might be behind one shard, and sometimes they might be
behind two shards we apply the default_shards feature skip to all docs
tests. That is, these tests will always run with the default number of
shards (one).
This folds the `:qa:smoke-test-reindex-with-all-modules` project into
`:modules:reindex` by declaring the reindex's integration testing
cluster requires the `parent-join` and `lang-painless` plugins and then
moving all of the integration tests that depended on parent-join and
painless into reindex.
It saves us one cluster start up during the build at the cost of a
little of the reindex module's "purity". Since the reindex module *does*
have unit tests that test scripting without painless I'm fairly ok with
that.
Previously `BulkProcessor` retry logic was based on the exception type of the failed response (`EsRejectedExecutionException`). This commit changes it to be based on the returned status code. This allows us to reproduce the same retry behaviour when the `BulkProcessor` is used from the high-level REST client, which was previously not the case as we cannot rebuild the same exception type when parsing back the response. This change has no effect on the transport client.
Closes#28885
This commit removes the http.enabled setting. While all real nodes (started with bin/elasticsearch) will always have an http binding, there are many tests that rely on the quickness of not actually needing to bind to 2 ports. For this case, the MockHttpTransport.TestPlugin provides a dummy http transport implementation which is used by default in ESIntegTestCase.
closes#12792
Many tests are added with a version check so that they do not run against a
version that doesn't have the feature yet. Master is 7.0, so all tests that
do not run against 6.0+ can be removed and the version check can be removed
on all tests that always run on 6.0+.
Adds two new methods to `RestClient` that take a `Request` object. These
methods will allows us to add more per-request customizable options
without creating more and more and more overloads of the `performRequest`
and `performRequestAsync` methods. These new methods look like:
```
Response performRequest(Request request)
```
and
```
void performRequestAsync(Request request, ResponseListener responseListener)
```
This change doesn't add any actual features but enables adding things like
per request timeouts and per request node selectors. This change *does*
rework the `HighLevelRestClient` and its tests to use these new `Request`
objects and it does update the docs.
We disable the reindex-from-old tests if we're running on windows or in
a directory that contains a space. This adds a warning to the logs when
we do that so that you can tell that it happened. This will be nice to
have when looking at CI and will be a hint to anyone developing locally.
This folds the `:qa:reindex-from-old` project into the `:modules:reindex`
project. This should speed up the build marginally by removing a single
clsuter start up at the cost of having to wait for old versions of
Elasticsearch to start up when checking reindex's integration tests.
Those don't take that long so this feels worth it.
This commit renames the bulk thread pool to the write thread pool. This
is to better reflect the fact that the underlying thread pool is used to
execute any document write request (single-document index/delete/update
requests, and bulk requests).
With this change, we add support for fallback settings
thread_pool.bulk.* which will be supported until 7.0.0.
We also add a system property so that the display name of the thread
pool remains as "bulk" if needed to avoid breaking users.
This change validates that the `_search` request does not have trailing
tokens after the main object and fails the request with a parsing exception otherwise.
Closes#28995
Some features have been deprecated since `6.0` like the `_parent` field or the
ability to have multiple types per index. This allows to remove quite some
code, which in-turn will hopefully make it easier to proceed with the removal
of types.
* Move ObjectParser into the x-content lib
This moves `ObjectParser`, `AbstractObjectParser`, and
`ConstructingObjectParser` into the libs/x-content dependency. This decoupling
allows them to be used for parsing for projects that don't want to depend on the
entire Elasticsearch jar.

The rejected execution handler API says that rejectedExecution(Runnable,
ThreadPoolExecutor) throws a RejectedExecutionException if the task must
be rejected due to capacity on the executor. We do throw something that
smells like a RejectedExecutionException (it is named
EsRejectedExecutionException) yet we violate the API because
EsRejectedExecutionException is not a RejectedExecutionException. This
has caused problems before where we try to catch RejectedExecution when
invoking rejectedExecution but this causes EsRejectedExecutionException
to go uncaught. This commit addresses this by modifying
EsRejectedExecutionException to extend
RejectedExecutionException.
Additionally:
* Included the existing update by query java api docs in java-api docs.
(for some reason it was never included, it needed some tweaking and
then it was good to go)
* moved delete-by-query / update-by-query code samples to java file so
that we can verify that these samples at least compile.
Closes#24203
* Decouple XContentBuilder from BytesReference
This commit removes all mentions of `BytesReference` from `XContentBuilder`.
This is needed so that we can completely decouple the XContent code and move it
into its own dependency.
While this change appears large, it is due to two main changes, moving
`.bytes()` and `.string()` out of XContentBuilder itself into static methods
`BytesReference.bytes` and `Strings.toString` respectively. The rest of the
change is code reacting to these changes (the majority of it in tests).
Relates to #28504
* 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
* Pass InputStream when creating XContent parser
Rather than passing the raw `BytesReference` in when creating the xcontent
parser, this passes the StreamInput (which is an InputStream), this allows us to
decouple XContent from BytesReference.
This also removes the use of `commons.Booleans` so it doesn't require more
external commons classes.
Related to #28504
* Undo boolean removal
* Enhance deprecation javadoc
* Remove deprecated createParser methods
This removes the final instances of the callers of `XContent.createParser` and
`XContentHelper.createParser` that did not pass in the `DeprecationHandler`. It
also removes the now-unused deprecated methods and fully removes any mention of
Log4j or LoggingDeprecationHandler from the XContent code.
Relates to #28504
* Add comments in JsonXContentGenerator
* Move more XContent.createParser calls to non-deprecated version
Part 2
This moves more of the callers to pass in the DeprecationHandler.
Relates to #28504
* Use parser's deprecation handler where appropriate
* Use logging handler in test that uses deprecated field on purpose
* Move to non-deprecated XContentHelper.createParser(...)
This moves away from one of the now-deprecated XContentHelper.createParser
methods in favor of specifying the deprecation logger at parser creation time.
Relates to #28449
Note that this doesn't move all the `createParser` calls because some of them
use the already-deprecated method that doesn't specify the XContentType.
* Remove the deprecated (and now non-needed) createParser method
This commit switches all the modules and server test code to use the
non-deprecated `ParseField.match` method, passing in the parser's deprecation
handler or the logging deprecation handler when a parser is not available (like
in tests).

Adds allow_partial_search_results flag to search requests with default setting = true.
When false, will error if search either timeouts, has partial errors or has missing shards rather
than returning partial search results. A cluster-level setting provides a default for search requests with no flag.
Closes#27435
This gives the test longer to block its updates. Now that we're checking
if the updates actually blocked saw that they may not do so in the
normal 10 seconds on a highly loaded system. And our jenkins machines
often function like highly loaded systems. Maybe this fixes#26758!
The rethrottle test fails from time to time because one of the child
task that want to be rethrottled hasn't properly started yet. We retry
in this case but it looks like the retry either isn't long enough or
something else strange is happening.
This change adds yet more logging so future failure of this kind will be
easier to track down and it adds an extra wait condition: this waits for
all child tasks to be running or completed before rethrottling. This
*might* avoid the failure because once a child task is properly started
it should be quite ok to rethrottle.
Relates to #26192
The test failure tracked by #28053 occurs because we fail to get the
failure response from the reindex on the first try and on our second try
the delete index API call that was supposed to trigger the failure
actually deletes the index during document creation. This causes the
test to fail catastrophically.
This PR attempts to wait for the failure to finish before the test moves
on to the second attempt. The failure doesn't reproduce locally for me
so I can't be sure that this helps at all with the failure, but it
certainly feels like it should help some. Here is hoping this prevents
similar failures in the future.
The test failure tracked by #26758 occurs when we cancel a running reindex
request that has been sliced into many children. The main reindex
response *looks* canceled but none of the children look canceled. This
is super strange because for the main request to look canceled for any
length of time one of the children has to be canceled.
This change adds additional logging to the test so we have more to go on
to debug this the next time it fails.
Sometimes modules/plugins depend on locally built elasticsearch jars.
This means not only that the jar is constantly changing (so no need for
a sha check), but also that the license falls under the Elasticsearch
license, and there is no need to keep another copy. This commit updates
the dependencies checked by dependencyLicenses to exclude those that are
built by elasticsearch.
Today Cross Cluster Search requires at least one node in each remote cluster to be up once the cross cluster search is run. Otherwise the whole search request fails despite some of the data (either local and/or remote) is available. This happens when performing the _search/shards calls to find out which remote shards the query has to be executed on. This scenario is different from shard failures that may happen later on when the query is actually executed, in case e.g. remote shards are missing, which is not going to fail the whole request but rather yield partial results, and the _shards section in the response will indicate that.
This commit introduces a boolean setting per cluster called search.remote.$cluster_alias.skip_if_disconnected, set to false by default, which allows to skip certain clusters if they are down when trying to reach them through a cross cluster search requests. By default all clusters are mandatory.
Scroll requests support such setting too when they are first initiated (first search request with scroll parameter), but subsequent scroll rounds (_search/scroll endpoint) will fail if some of the remote clusters went down meanwhile.
The search API response contains now a new _clusters section, similar to the _shards section, that gets returned whenever one or more clusters were disconnected and got skipped:
"_clusters" : {
"total" : 3,
"successful" : 2,
"skipped" : 1
}
Such section won't be part of the response if no clusters have been skipped.
The per cluster skip_unavailable setting value has also been added to the output of the remote/info API.
This is a followup to #26521. This commit expands the alias added for
the elasticsearch client codebase to all codebases. The original full
jar name property is left intact. This only adds an alias without the
version, which should help ease the pain in updating any versions (ES
itself or dependencies).
When a search is executing locally over many shards, we can stack
overflow during query phase execution. This happens due to callbacks
that occur after a phase completes for a shard and we move to the same
phase on another shard. If all the shards for the query are local to the
local node then we will never go async and these callbacks will end up
as recursive calls. With sufficiently many shards, this will end up as a
stack overflow. This commit addresses this by truncating the stack by
forking to another thread on the executor for the phase.

The headers passed to reindex were skipped except for the last one. This
commit fixes the copying of the headers, as well as adds a base test
case for rest client builders to access the headers within the built
rest client.

We were accidentally defaulting it to the scroll size.
Untwists some of the tricks that we play with parsing
so that the size is no longer scrambled.
Closes#26761
This change adds a fromXContent method to Settings that allows to read
the xcontent that is produced by toXContent. It also replaces the entire settings
loader infrastructure and removes the structured map representation. Future PRs will
also tackle the `getAsMap` that exposes the internal represenation of settings for
better encapsulation.
Security manager policy files contains grants for specific codebases,
where a codebase is a jar file. We use a system property containing the
name of the jar file to resolve the jar file location when parsing the
policy file. However, this means the version of the jars must be
modified when versions of dependencies change. This is particularly
messy for elasticsearch, where we now have a dependency on the rest
client, and need to support both a snapshot version for testing and non
snapshot for release.
This commit adds an alias for the elasticsearch rest client without a
version to be used in policy files. That allows the policy files to not care whether
the rest client is a snapshot or release.
