As part of adding support for new API to the high-level REST client,
we added support for the `flat_settings` parameter to some of our
request classes. We added documentation that such flag is only ever
read by the high-level REST client, but the truth is that it doesn't
do anything given that settings are always parsed back into a `Settings`
object, no matter whether they are returned in a flat format or not.
It was a mistake to add support for this flag in the context of the
high-level REST client, hence this commit removes it.
The following is the current behaviour, tested now through a specific
test.
The low-level REST client doesn't add a leading wildcard when not
provided, unless a `pathPrefix` is configured in which case a trailing
slash will be automatically added when concatenating the prefix and the
provided uri.
Also when configuring a pathPrefix, if it doesn't start with a '/' it
will be modified by adding the missing leading '/'.
CRUD: Parsing changes for UpdateRequest (#29293)
Use `ObjectParser` to parse `UpdateRequest` so we reject unknown fields
and drop support for the `_fields` parameter because it was deprecated
in 5.x.
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.
Currently the ranking evaluation API doesn't support many of the
standard parameters of the search API. Some of these make sense, like
adding support for the common indices options parameters, which this
change adds.
When the `BulkProcessor` is used with the high-level REST client, a scheduler is internally created that allows to schedule tasks. Such scheduler is not exposed to users and needs to be closed once the `BulkProcessor` is closed. There are two ways to close the `BulkProcessor` though, one is the ordinary `close` method and the other one is `awaitClose`. The former closes the scheduler while the latter doesn't, leaving threads lingering.
* Remove all dependencies from XContentBuilder
This commit removes all of the non-JDK dependencies from XContentBuilder, with
the exception of `CollectionUtils.ensureNoSelfReferences`. It adds a third
extension point around dealing with time-based fields and formatters to work
around the Joda dependency.
This decoupling allows us to be able to move XContentBuilder to a separate lib
so it can be available for things like the high level rest client.
Relates to #28504
This was the plan from day one but due to a silly bug nodes were immediately retried after they were marked as dead for the first time. From the second time on, the expected backoff was applied.
Some source files seem to have the execute bit (a+x) set, which doesn't
really seem to hurt but is a bit odd. This change removes those, making
the permissions similar to other source files in the repository.
Adds docs for `HighLevelRestClient#multiSearch`. Unlike the `multiGet`
docs these are much more sparse because multi-search doesn't support
setting many options on the `MultiSearchRequest` and instead just wraps
a list of `SearchRequest`s.
Closes#28389
Currently we store the indices specified in the request URL together with all
the other ranking evaluation specification in RankEvalSpec. This is not ideal
since e.g. the indices are not rendered to xContent and so cannot be parsed
back. Instead we should keep them in RankEvalRequest.
Adds SSLHandshakeException to the list of Exceptions that are
specifically rethrown from the async thread so its type is preserved.
This should make it easier to debug synchronous calls with ssl issues.
In the past the Low Level REST Client was super careful not to wrap
any exceptions that it throws from synchronous calls so that callers can
catch the exceptions and work with them. The trouble with that is that
the exceptions are originally thrown on the async thread pool and then
transfered back into calling thread. That means that the stack trace of
the exception doesn't have the calling method which is *super* *ultra*
confusing.
This change always wraps exceptions transferred from the async thread
pool so that the stack trace of the thrown exception contains the
caller's stack. It tries to preserve the type of the throw exception but
this is quite a fiddly thing to get right. We have to catch every type
of exception that we want to preserve, wrap with the same type and
rethrow. I've preserved the types of all exceptions that we had tests
mentioning but no other exceptions. The other exceptions are either
wrapped in `IOException` or `RuntimeException`.
Closes#28399
* 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
The REST status 503 means "I can not handle the request that you sent
me." However today we respond to a main request with a 503 when there
are certain cluster blocks despite still responding with an actual main
response. This is broken, we should respond with a 200 status. This
commit removes this silliness.
The recent addition of the _cluster/settings API was merged together with another change that added encoding of the different URL parts. That broke the cluster PUT settings API straight-away. This commit fixes this problem. The '/' that's part of the /_cluster/settings endpoint should not be encoded.
The REST high-level client supports now encoding of path parts, so that for instance documents with valid ids, but containing characters that need to be encoded as part of urls (`#` etc.), are properly supported. We also make sure that each path part can contain `/` by encoding them properly too.
Closes#28625
* 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
* [DOCS] expand examples on providing mappings for create index and put mapping
The create index API and put mappings API docs the for high-level Java REST client didn't have a lot of info on how to provide mappings. This commit adds some examples.
This commit splits the async execution documentation into 2 parts, one
for the async method itself and one for the action listener. This allows
to add more doc and to use CountDownLatches in doc tests to wait for
asynchronous operations to be completed before moving to the next test.
It also renames few files.
Related to #28457
Similarly to other documentation tests in the high level client, the
asynchronous operation like update, index or delete can make the test
fail if it sneak in between the middle of another operation.
This commit moves the async doc tests to be the last ones executed and
adds assert busy loops to ensure that the asynchronous operations are
correctly terminated.
