This commit exposes the executor service interface from thread
pool. This will enable some high-level concurrency primitives that will
make some code cleaner and simpler.

In the test for reindex and friend's rethrottling feature we were waiting
only for a single reindex sub task to start before rethrottling. This
mostly worked because starting tasks is fast. But it didn't *always work
and CI found that for us. This fixes the test to wait for all subtasks
to start before rethrottling.
I reproduced this locally semi-consistently with some fairly creative
`Thread.sleep` calls and this test fix fixes the issue even with the
sleeps so I'm fairly sure this will work consistently.
Closes#21446
The method used to be called `isSourceEmpty`, and was renamed to `hasSource`, but the return value never changed. Updated tests and users accordingly.
Closes#21419
If you try to reindex with multiple slices against a node that
doesn't support it we throw an `IllegalArgumentException` so
`assertVersionSerializable` is ok with it and so if this happens
in REST it comes back as a 400 error.
* Rest client: don't reuse that same HttpAsyncResponseConsumer across multiple retries
Turns out that AbstractAsyncResponseConsumer from apache async http client is stateful and cannot be reused across multiple requests. The failover mechanism was mistakenly reusing that same instance, which can be provided by users, across retries in case nodes are down or return 5xx errors. The downside is that we have to change the signature of two public methods, as HttpAsyncResponseConsumer cannot be provided directly anymore, rather its factory needs to be provided which is going to be used to create one instance of the consumer per request attempt.
Up until now we tested our RestClient against multiple nodes only in a mock environment, where we don't really send http requests. In that scenario we can verify that retries etc. work properly but the interaction with the http client library in a real scenario is different and can catch other problems. With this commit we also add an integration test that sends requests to multiple hosts, and some of them may also get stopped meanwhile. The specific test for pathPrefix was also removed as pathPrefix is now randomly applied by default, hence implicitly tested. Moved also a small test method that checked the validity of the path argument to the unit test RestClientSingleHostTests.
Also increase default buffer limit to 100MB and make it required in default consumer
The default buffer limit used to be 10MB but that proved not to be high enough for scroll requests (see reindex from remote). With this commit we increase the limit to 100MB and make it a bit more visibile in the consumer factory.
At one point in the past when moving out the rest tests from core to
their own subproject, we had multiple test classes which evenly split up
the tests to run. However, we simplified this and went back to a single
test runner to have better reproduceability in tests. This change
removes the remnants of that multiplexing support.
Adds support for `?slices=N` to reindex which automatically
parallelizes the process using parallel scrolls on `_uid`. Performance
testing sees a 3x performance improvement for simple docs
on decent hardware, maybe 30% performance improvement
for more complex docs. Still compelling, especially because
clusters should be able to get closer to the 3x than the 30%
number.
Closes#20624
It was 10mb and that was causing trouble when folks reindex-from-remoted
with large documents.
We also improve the error reporting so it tells folks to use a smaller
batch size if they hit a buffer size exception. Finally, adds some docs
to reindex-from-remote mentioning the buffer and giving an example of
lowering the size.
Closes#21185
Versions before 2.0 needed to be told to return interesting fields
like `_parent`, `_routing`, `_ttl`, and `_timestamp`. And they come
back inside a `fields` block which we need to parse.
Closes#21044
This allows you to whitelist `localhost:*` or `127.0.10.*:9200`.
It explicitly checks for patterns like `*` in the whitelist and
refuses to start if the whitelist would match everything. Beyond
that the user is on their own designing a secure whitelist.
This change proposes the removal of all non-tcp transport implementations. The
mock transport can be used by default to run tests instead of local transport that has
roughly the same performance compared to TCP or at least not noticeably slower.
This is a master only change, deprecation notice in 5.x will be committed as a
separate change.
Today when parsing a request, Elasticsearch silently ignores incorrect
(including parameters with typos) or unused parameters. This is bad as
it leads to requests having unintended behavior (e.g., if a user hits
the _analyze API and misspell the "tokenizer" then Elasticsearch will
just use the standard analyzer, completely against intentions).
This commit removes lenient URL parameter parsing. The strategy is
simple: when a request is handled and a parameter is touched, we mark it
as such. Before the request is actually executed, we check to ensure
that all parameters have been consumed. If there are remaining
parameters yet to be consumed, we fail the request with a list of the
unconsumed parameters. An exception has to be made for parameters that
format the response (as opposed to controlling the request); for this
case, handlers are able to provide a list of parameters that should be
excluded from tripping the unconsumed parameters check because those
parameters will be used in formatting the response.
Additionally, some inconsistencies between the parameters in the code
and in the docs are corrected.

reindex-from-remote should ignore unknown fields so it is mostly

option to `ObjectParser` and `ConstructingObjectParser` that, if

When Netty 4 was introduced, it was not the default network
implementation. Some tests were constructed to randomly use Netty 4
instead of the default network implementation. When Netty 4 was made the
default implementation, these tests were not updated. Thus, these tests
are randomly choosing between the default network implementation (Netty
4) and Netty 4. This commit updates these tests to reverse the role of
Netty 3 and Netty 4 so that the randomization is choosing between Netty
3 and the default (again, now Netty 4).

This commit modifies the call sites that allocate a parameterized
message to use a supplier so that allocations are avoided unless the log
level is fine enough to emit the corresponding log message.
This change adds a special field named _none_ that allows to disable the retrieval of the stored fields in a search request or in a TopHitsAggregation.
To completely disable stored fields retrieval (including disabling metadata fields retrieval such as _id or _type) use _none_ like this:
````
POST _search
{
"stored_fields": "_none_"
}
````
Currently, bulk item requests can be any ActionRequest, this commit
restricts bulk item requests to DocumentRequest. This simplifies
handling failures during bulk requests. Additionally, a new enum
is added to DocumentRequest to represent the intended operation
to be performed by a document request. Now, index operation type
also uses the new enum to specify whether the request should
create or index a document.
Reindex intentionally tries to fail the search operation to make sure
that the exception flows back. The exception message changed so we
should catch the appropriate exception.
This test was failing in the presence of transport clients. This turns
off transport clients while I fix the test so it doesn't fail for
everyone in the mean time.
The big change here is cleaning up the `TaskListResponse` so it doesn't
have a breaky `toString` implementation. That was causing the reindex
tests to break.
Also removed `NetworkModule#registerTaskStatus` which is part of the
Plugin API. Use `Plugin#getNamedWriteables` instead.
Parsing a search request is currently split up among a number of
classes, using multiple public static methods, which take multiple
regstries of elements that may appear in the search request like query
parsers and aggregations. This change begins consolidating all this code
by collapsing the registries normally used for parsing search requests
into a single SearchRequestParsers class. It is also made available to
plugin services to enable templating of search requests. Eventually all
of the actual parsing logic should move to the class, and the registries
should be hidden, but for now they are at least co-located to reduce the
number of objects that must be passed around.
Squashes all the subpackages of `org.elasticsearch.rest.action` down to
the following:
* `o.e.rest.action.admin` - Administrative actions
* `o.e.rest.action.cat` - Actions that make tables for `grep`ing
* `o.e.rest.action.document` - Actions that act on documents
* `o.e.rest.action.ingest` - Actions that act on ingest pipelines
* `o.e.rest.action.search` - Actions that search
I'm tempted to merge `search` into `document` but the `document`
package feels fairly complete as is and `Suggest` isn't actually always
about documents either....
I'm also tempted to merge `ingest` into `admin.cluster` because the
latter contains the actions for dealing with stored scripts.
I've moved the `o.e.rest.action.support` into `o.e.rest.action`.
I've also added `package-info.java`s to all packges in `o.e.rest`. I
figure if the package is too small to deserve a `package-info.java` file
then it is too small to deserve to be a package....
Also fixes checkstyle in all moved classes.
The term persisted task was used to indicate that a task should store its results upon its completion. We would like to use this term to indicate that a task can survive restart of nodes instead. This commit removes usages of the term "persist" when it means store results.
