`PreferHasAttributeNodeSelector` works like exactly like
`HasAttributeNodeSelector` but if not nodes match the attribute
then it will not filter the list of nodes.
We use wrap code in `// tag` and `//end` to include it in our docs. Our
current docs style wraps code snippets in a box that is only wide enough
for 76 characters and adds a horizontal scroll bar for wider snippets
which makes the snippet much harder to read. This adds a checkstyle check
that looks for java code that is included in the docs and is wider than
that 76 characters so all snippets fit into the box. It solves many of
the failures that this catches but suppresses many more. I will clean
those up in a follow up change.
Introduces `RestClientBuilder#setStrictDeprecationMode` which defaults
to false but when set to true, causes a rest request to fail if a
deprecation warning header comes back in the response from Elasticsearch.
This should be valueable to Elasticsearch's tests, especially those of the
High Level REST Client where they will help catch divergence between the
client and the server.
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. In a
long series of PRs I've changed all of the old style requests. This
drops the deprecated methods and will be released with 7.0.
Ensure our tests can run in a FIPS JVM
JKS keystores cannot be used in a FIPS JVM as attempting to use one
in order to init a KeyManagerFactory or a TrustManagerFactory is not
allowed.( JKS keystore algorithms for private key encryption are not
FIPS 140 approved)
This commit replaces JKS keystores in our tests with the
corresponding PEM encoded key and certificates both for key and trust
configurations.
Whenever it's not possible to refactor the test, i.e. when we are
testing that we can load a JKS keystore, etc. we attempt to
mute the test when we are running in FIPS 140 JVM. Testing for the
JVM is naive and is based on the name of the security provider as
we would control the testing infrastrtucture and so this would be
reliable enough.
Other cases of tests being muted are the ones that involve custom
TrustStoreManagers or KeyStoreManagers, null TLS Ciphers and the
SAMLAuthneticator class as we cannot sign XML documents in the
way we were doing. SAMLAuthenticator tests in a FIPS JVM can be
reenabled with precomputed and signed SAML messages at a later stage.
IT will be covered in a subsequent PR
There have been changes in error messages for `SSLHandshakeException`.
This has caused a couple of failures in our tests.
This commit modifies test verification to assert on exception type of
class `SSLHandshakeException`.
There was another issue in Java11 which caused NPE. The bug has now
been fixed on Java11 - early access build 22.

In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `client/rest` project to use the new versions.
Some proxies require all requests to have paths starting with / since
there are no relative paths at the HTTP connection level. Elasticsearch
assumes paths are absolute. In order to run rest tests against a cluster
behind such a proxy, set the system property
tests.rest.client_path_prefix to /.

With this change the `test` task becomes nothing more than an alias for `utest`.
Some of the stand alone tests that had a `test` task now have `integTest`, and a
few of them that used to have `integTest` to run multiple tests now only
have `check`.
This will also help separarate unit/micro tests from integration tests.

We recently introduced a mechanism that allows to specify a node
selector as part of do sections (see #31471). When a node selector that
is not the default one is configured, a new client will be initialized
with the same properties as the default one, but with the specified
node selector. This commit improves such mechanism but also closing
the additional clients being created and adding equals/hashcode impl to
the custom node selector as they are cached into a map.
We have made node selectors configurable per request, but all
of other language clients don't allow for that.
A good reason not to do so, is that having a different node selector
per request breaks round-robin. This commit makes NodeSelector
configurable only at client initialization. It also improves the docs
on this matter, important given that a single node selector can still
affect round-robin.
Add a `NodeSelector` so that users can filter the nodes that receive
requests based on node attributes.
I believe we'll need this to backport #30523 and we want it anyway.
I also added a bash script to help with rebuilding the sniffer parsing
test documents.
Allows users of the Low Level REST client to specify which hosts a
request should be run on. They implement the `NodeSelector` interface
or reuse a built in selector like `NOT_MASTER_ONLY` to chose which nodes
are valid. Using it looks like:
```
Request request = new Request("POST", "/foo/_search");
RequestOptions options = request.getOptions().toBuilder();
options.setNodeSelector(NodeSelector.NOT_MASTER_ONLY);
request.setOptions(options);
...
```
This introduces a new `Node` object which contains a `HttpHost` and the
metadata about the host. At this point that metadata is just `version`
and `roles` but I plan to add node attributes in a followup. The
canonical way to **get** this metadata is to use the `Sniffer` to pull
the information from the Elasticsearch cluster.
I've marked this as "breaking-java" because it breaks custom
implementations of `HostsSniffer` by renaming the interface to
`NodesSniffer` and by changing it from returning a `List<HttpHost>` to a
`List<Node>`. It *shouldn't* break anyone else though.
Because we expect to find it useful, this also implements `host_selector`
support to `do` statements in the yaml tests. Using it looks a little
like:
```
---
"example test":
- skip:
features: host_selector
- do:
host_selector:
version: " - 7.0.0" # same syntax as skip
apiname:
something: true
```
The `do` section parses the `version` string into a host selector that
uses the same version comparison logic as the `skip` section. When the
`do` section is executed it passed the off to the `RestClient`, using
the `ElasticsearchHostsSniffer` to sniff the required metadata.
The idea is to use this in mixed version tests to target a specific
version of Elasticsearch so we can be sure about the deprecation
logging though we don't currently have any examples that need it. We do,
however, have at least one open pull request that requires something
like this to properly test it.
Closes#21888
This modifies the high level rest client to allow calling code to
customize per request options for the bulk API. You do the actual
customization by passing a `RequestOptions` object to the API call
which is set on the `Request` that is generated by the high level
client. It also makes the `RequestOptions` a thing in the low level
rest client. For now that just means you use it to customize the
headers and the `httpAsyncResponseConsumerFactory` and we'll add
node selectors and per request timeouts in a follow up.
I only implemented this on the bulk API because it is the first one
in the list alphabetically and I wanted to keep the change small
enough to review. I'll convert the remaining APIs in a followup.
This commit reworks the Sniffer component to simplify it and make it possible to test it.
In particular, it no longer takes out the host that failed when sniffing on failure, but rather relies on whatever the cluster returns. This is the result of some valid comments from #27985. Taking out one single host is too naive, hard to test and debug.
A new Scheduler abstraction is introduced to abstract the tasks scheduling away and make it possible to plug in any test implementation and take out timing aspects when testing.
Concurrency aspects have also been improved, synchronized methods are no longer required. At the same time, we were able to take #27697 and #25701 into account and fix them, especially now that we can more easily add tests.
Last but not least, unit tests are added for the Sniffer component, long overdue.
Closes#27697Closes#25701
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
The default behaviour for Apache HTTP client is to mimic the standard
browser behaviour of clearing the authentication cache (for a given
host) if that host responds with 401.
This behaviour is appropriate in a interactive browser environment
where the user is given the opportunity to provide alternative
credentials, but it is not the preferred behaviour for the ES REST
client.
X-Pack may respond with a 401 status if a request is made before the
node/cluster has recovered sufficient state to know how to handle the
provided authentication credentials - for example the security index
need to be recovered before we can authenticate native users.
In these cases the correct behaviour is to retry with the same
credentials (rather than discarding those credentials).
These tests are sharing the same server and client for every test. Yet,
we are seeing some tests fail with mysterious connection resets. It is
not clear what is happening but one theory is that the tests are
interfering with each other. This commit moves to use a separate server
and client per test.
We've been setting this value to 500ms in the default low-level REST
client configuration, misunderstanding the effect that it would have.
This proved very problematic, as it ends up causing `TimeoutException`
returned from the leased pool in some cases even for successful requests.
Closes#24069
Deprecate the many arguments versions of `performRequest` and
`performRequestAsync` in favor of the `Request` object flavored variants
introduced in #29623. We'll be dropping the many arguments variants in
7.0 because they make it difficult to add new features in a backwards
compatible way and they create a *ton* of intellisense noise.
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.
The low-level REST client targets JDK 7. To avoid compiling against JDK
functionality not available in JDK 7, we use animal sniffer. However,
when we switched to using the JDK 9 and now the JDK 10 compiler which
has built-in support for targeting previous JDKs, we no longer need to
use animal sniffer. This is because the JDK is now packaged with the
signatures needed to ensure that when we target JDK 7 at compile-time it
is detected that we are only using JDK 7 functionality. This commit
removes the use of animal sniffer from the low-level REST client build.
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 '/'.
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.
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
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
This is related to #27933. It introduces a jar named elasticsearch-core
in the lib directory. This commit moves the JarHell class from server to
elasticsearch-core. Additionally, PathUtils and some of Loggers are
moved as JarHell depends on them.
This commit removes the usage of system properties for the HttpAsyncClient as this overrides some
defaults that we intentionally change. In order to set the default SSLContext to the system context
we set the SSLContext on the builder explicitly.
Closes#27827
