With this commit we add a monotonically strict timer to ensure time is
advancing even if the timer is called in a tight loop in tests. We also
relax a condition in a similar test so it only checks that time is not
moving backwards.
Closes#33747
The apache commons http client implementations recently released
versions that solve TLS compatibility issues with the new TLS engine
that supports TLSv1.3 with JDK 11. This change updates our code to
use these versions since JDK 11 is a supported JDK and we should
allow the use of TLSv1.3.
The LLRC's exception handling for strict mode was previously throwing an
exception the HLRC assumed was an error response. This is not the case
if the result is valid in strict mode, as it will return the proper
response wrapped in an exception with warnings. This commit fixes the
HLRC such that it no longer spews if it encounters a strict LLRC
response.
Closes#37090
* Testing conventions now checks for tests in main
This is the last outstanding feature of the old NamingConventionsTask,
so time to remove it.
* PR review
This commit removes the warn-date from warning headers. Previously we
were stamping every warning header with when the request
occurred. However, this has a severe performance penalty when
deprecation logging is called frequently, as obtaining the current time
and formatting it properly is expensive. A previous change moved to
using the startup time as the time to stamp on every warning header, but
this was only to prove that the timestamping was expensive. Since the
warn-date is optional, we elect to remove it from the warning
header. Prior to this commit, we worked in Kibana to make the warn-date
treated as optional there so that we can follow-up in Elasticsearch and
remove the warn-date. This commit does that.
This allows you to plug the behavior that the LLRC uses to handle
warnings on a per request basis.
We entertained the idea of allowing you to set the warnings behavior to
strict mode on a per request basis but that wouldn't allow the high
level rest client to fail when it sees an unexpected warning.
We also entertained the idea of adding a list of "required warnings" to
the `RequestOptions` but that won't work well with failures that occur
*sometimes* like those we see in mixed clusters.
Adding a list of "allowed warnings" to the `RequestOptions` would work
for mixed clusters but it'd leave many of the assertions in our tests
weaker than we'd like.
This behavior plugging implementation allows us to make a "required
warnings" option when we need it and an "allowed warnings" behavior when
we need it.
I don't think this behavior is going to be commonly used by used outside
of the Elasticsearch build, but I expect they'll be a few commendably
paranoid folks who could use this behavior.
`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 /.

Closes#31324. The issue has full context in comments.
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.
