When a replica is fully recovered (i.e., in `POST_RECOVERY` state) we send a request to the master
to start the shard. The master changes the state of the replica and publishes a cluster state to that
effect. In certain cases, that cluster state can be processed on the node hosting the replica
*together* with a cluster state that promotes that, now started, replica to a primary. This can
happen due to cluster state batched processing or if the master died after having committed the
cluster state that starts the shard but before publishing it to the node with the replica. If the master
also held the primary shard, the new master node will remove the primary (as it failed) and will also
immediately promote the replica (thinking it is started).
Sadly our code in IndexShard didn't allow for this which caused [assertions](13917162ad/server/src/main/java/org/elasticsearch/index/seqno/ReplicationTracker.java (L482)) to be tripped in some of our tests runs.
Sometimes we have a test failure that hits an `UnsupportedOperationException` in this infrastructure. When
debugging you want to know what caused this unexpected failure, but right now we're silent about it. This
commit adds some information to the `UnsupportedOperationException`
Relates to #32127
With the introduction of sequence number, we no longer use versionType to
resolve out of order collision in replication and recovery requests.
This PR removes removes the versionType from translog. We can only remove
it in 7.0 because it is still required in a mixed cluster between 6.x and 5.x.
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
With this commit we disable the real-memory circuit breaker in tests
that inherit from `ESSingleNodeTestCase`. As this breaker is based on
real memory usage over which we have no (full) control in tests and
their purpose is also not to test the circuit breaker, we use the
deterministic circuit breaker implementation that only accounts for
explicitly reserved memory.

* Adjust mock script plugin in IT for new API
* Adds a new auto-interval date histogram
This change adds a new type of histogram aggregation called `auto_date_histogram` where you can specify the target number of buckets you require and it will find an appropriate interval for the returned buckets. The aggregation works by first collecting documents in buckets at second interval, when it has created more than the target number of buckets it merges these buckets into minute interval bucket and continues collecting until it reaches the target number of buckets again. It will keep merging buckets when it exceeds the target until either collection is finished or the highest interval (currently years) is reached. A similar process happens at reduce time.
This aggregation intentionally does not support min_doc_count, offest and extended_bounds to keep the already complex logic from becoming more complex. The aggregation accepts sub-aggregations but will always operate in `breadth_first` mode deferring the computation of sub-aggregations until the final buckets from the shard are known. min_doc_count is effectively hard-coded to zero meaning that we will insert empty buckets where necessary.

Added some notes in the documentation about the intervals that can bbe

Also added a test case that utilises the merging of conseecutive buckets
* Fixes performance bug
The bug meant that getAppropriate rounding look a huge amount of time
if the range of the data was large but also sparsely populated. In
these situations the rounding would be very low so iterating through
the rounding values from the min key to the max keey look a long time
(~120 seconds in one test).
The solution is to add a rough estimate first which chooses the
rounding based just on the long values of the min and max keeys alone
but selects the rounding one lower than the one it thinks is
appropriate so the accurate method can choose the final rounding taking
into account the fact that intervals are not always fixed length.

With this commit we introduce a new circuit-breaking strategy to the parent
circuit breaker. Contrary to the current implementation which only accounts for
memory reserved via child circuit breakers, the new strategy measures real heap
memory usage at the time of reservation. This allows us to be much more
aggressive with the circuit breaker limit so we bump it to 95% by default. The
new strategy is turned on by default and can be controlled with the new cluster
setting `indices.breaker.total.userealmemory`.
Note that we turn it off for all integration tests with an internal test cluster
because it leads to spurious test failures which are of no value (we cannot
fully control heap memory usage in tests). All REST tests, however, will make
use of the real memory circuit breaker.

Currently AbstractXContentTestCase#testFromXContent appends random fields, but in
a fixed position. This PR shuffles all fields after the random fields have been appended,
hence the random fields are actually added to random positions.
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This

A newly added class called DateFormatters now contains java.time based
builders for dates, which also intends to be fully backwards compatible,
when the name based date formatters are picked. Also a new class named
CompoundDateTimeFormatter for being able to parse multiple different
formats has been added.
A duelling test class has been added that ensures the same dates when
parsing java or joda time formatted dates for the name based dates.
Note, that java.time and joda time are not fully backwards compatible,
which also means that old formats will currently not work with this
setup.
At the end of every `ESRestTestCase` we clean the cluster which includes
deleting all of the templates. If xpack is installed it'll automatically
recreate a few templates every time they are removed. Which is slow.
This change stops the cleanup from removing the xpack templates. It cuts
the time to run the docs tests more than in half and it probably saves a
bit more time on other tests as well.
Today TransportService is tightly coupled with Transport since it
requires an instance of TransportService in order to receive responses
and send requests. This is mainly due to the Request and Response handlers
being maintained in TransportService but also because of the lack of a proper
callback interface.
This change moves request handler registry and response handler registration into
Transport and adds all necessary methods to `TransportConnectionListener` in order
to remove the `TransportService` dependency from `Transport`
Transport now accepts one or more `TransportConnectionListener` instances that are
executed sequentially in a blocking fashion.
Adds a new parameter to the BlobContainer#write*Blob methods to specify whether the existing file
should be overridden or not. For some metadata files in the repository, we actually want to replace
the current file. This is currently implemented through an explicit blob delete and then a fresh write.
In case of using a cloud provider (S3, GCS, Azure), this results in 2 API requests instead of just 1.
This change will therefore allow us to achieve the same functionality using less API requests.
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 /.
This commit removes some tests in the repository-s3 plugin that
have not been executed for 2+ years but have been maintained
for nothing. Most of the tests in AbstractAwsTestCase were
obsolete or superseded by fixture based integration tests.
The TaskManager and TaskAwareRequest could return null when registering

We added a way to close the yaml test client with #31575.
Such close method also needs to be called from the test suite though for
the additional clients to be closed.
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.

This creates a YAML test "features" that indices if the cluster being
tested has xpack installed (`xpack`) or if it does *not* have xpack
installed (`no_xpack`). It uses those features to centralize skipping
a few tests that fail if xpack is installed.
The plan is to use this in a followup to skip docs tests that require
xpack when xpack is not installed. We *plan* to use the declaration
of required license level on the docs page to generate the required
`skip`.
Closes#30933.
Currently RandomObjects::addFields can potentially generate a large number of fields This commit decreases the chances that a new object or array is added as a new branch of an object, which lowers the probability of ending up with very big documents generated.

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.
TransportRequestHandler currently contains 2 messageReceived methods,
one which takes a Task, and one that does not. The first just delegates
to the second. This commit changes all existing implementors of
TransportRequestHandler to implement the version which takes Task, thus
allowing the class to be a functional interface, and eliminating the
need to throw exceptions when a task needs to be ensured.
Introduces support for multiple host providers, which allows the settings based hosts resolver to be
treated just as any other UnicastHostsProvider. Also introduces the notion of a HostsResolver so
that plugins such as FileBasedDiscovery do not need to create their own thread pool for resolving
hosts, making it easier to add new similar kind of plugins.
With #20695 we removed local transport and there is just TransportAddress now. The
UnicastHostsProvider currently returns DiscoveryNode instances, where, during pinging, we're
actually only making use of the TransportAddress to establish a first connection to the possible new
node. To simplify the interface, we can just return a list of transport addresses instead, which
means that it's not necessary anymore to create fake node objects in each plugin just to return the
address information.
Currently we set local addresses on the creation time of a NioChannel.
However, this may return null as the local address may not have been
set yet. An example is the local address has not been set on a client
channel as the connection process is not yet complete.
This PR modifies the getter to set the local field if it is currently null.
Historically in TcpTransport server channels were represented by the
same channel interface as socket channels. This was necessary as
TcpTransport was parameterized by the channel type. This commit
introduces TcpServerChannel and HttpServerChannel classes. Additionally,
it adds the implementations for the various transports. This allows
server channels to have unique functionality and not implement the
methods they do not support (such as send and getRemoteAddress).
Additionally, with the introduction of HttpServerChannel this commit
extracts some of the storing and closing channel work to the abstract
http server transport.
The QueryCachingPolicy#ALWAYS_CACHE was deprecated in Lucene-7.4 and
will be removed in Lucene-8.0. This change replaces it with QueryCachingPolicy.
This also makes INDEX_QUERY_CACHE_EVERYTHING_SETTING visible in testing only.
This is a general cleanup of channels and exception handling in http.
This commit introduces a CloseableChannel that is a superclass of
TcpChannel and HttpChannel. This allows us to unify the closing logic
between tcp and http transports. Additionally, the normal http channels
are extracted to the abstract server transport.
Finally, this commit (mostly) unifies the exception handling between nio
and netty4 http server transports.
Since #30966, Action no longer has anything but a call to the
GenericAction super constructor. This commit renames GenericAction
into Action, thus eliminating the Action class. Additionally, this
commit removes the Request generic parameter of the class, since
it was unused.
If we are running into a race condition between a node being configured
to be a remote node for cross cluster search etc. and that node joining
the cluster we might connect to that node with a remote profile. If that
node now joins the cluster it connected to it as a CCS remote node we use
the wrong profile and can't use bulk connections etc. anymore. This change
uses the remote profile only if we connect to a node that has a different cluster
name than the local cluster. This is not a perfect fix for this situation but
is the safe option while potentially only loose a small optimization of using
less connections per node which is small anyways since we only connect to a
small set of nodes.
Closes#29321
This commit adds the is-write-index flag for aliases.
It allows requests to set the flag, and responses to display the flag.
It does not validate and/or affect any indexing/getting/updating behavior
of Elasticsearch -- this will be done in a follow-up PR.
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.
We might lose messages between getCapturedRequestsAndClear calls.
This commit makes sure that both getCapturedRequestsAndClear and
getCapturedRequestsByTargetNodeAndClear are atomic.
This is related to #28898. With the addition of the http nio transport,
we now have two different modules that provide http transports.
Currently most of the http logic lives at the module level. However,
some of this logic can live in server. In particular, some of the
setting of headers, cors, and pipelining. This commit begins this moving
in that direction by introducing lower level abstraction (HttpChannel,
HttpRequest, and HttpResonse) that is implemented by the modules. The
higher level rest request and rest channel work can live entirely in
server.
Many fixtures have similar code for writing the pid & ports files or
for handling HTTP requests. This commit adds an AbstractHttpFixture
class in the test framework that can be extended for specific testing purposes.
The `requires_replica` yaml test feature hasn't worked for years. This
is what happens if you try to use it:
```

None of our tests use it.
TransportAction has many variants of execute. One of those variants
executes by returning a future, which is then often blocked on by
calling get(). This commit removes this variant of execute, instead
using a helper method for tests that want to block, or having tests
pass in a PlainActionFuture directly as a listener.

Given the weirdness of the response returned by the get alias API, we went for a client specific response, which allows us to hold the error message, exception and status returned as part of the response together with aliases. See #30536 .
Relates to #27205
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 removes the abstract `getTranslog` method in `Engine`, instead leaving it
to the abstract implementations of the other methods that use the translog. This
allows future Engines not to have a Translog, as instead they must implement the
methods that use the translog pieces to return necessary values.
The goal of this commit is to address unknown licenses when producing
the dependencies info report. We have two different checks that we run
on licenses. The first check is whether or not we have stashed a copy of
the license text for a dependency in the repository. The second is to
map every dependency to a license type (e.g., BSD 3-clause). The problem
here is that the way we were handling licenses in the second check
differs from how we handle licenses in the first check. The first check
works by finding a license file with the name of the artifact followed
by the text -LICENSE.txt. Yet in some cases we allow mapping an artifact
name to another name used to check for the license (e.g., we map
lucene-.* to lucene, and opensaml-.* to shibboleth. The second check
understood the first way of looking for a license file but not the
second way. So in this commit we teach the second check about the
mappings from artifact names to license names. We do this by copying the
configuration from the dependencyLicenses task to the dependenciesInfo
task and then reusing the code from the first check in the second
check. There were some other challenges here though. For example,
dependenciesInfo was checking too many dependencies. For now, we should
only be checking direct dependencies and leaving transitive dependencies
from another org.elasticsearch artifact to that artifact (we want to do
this differently in a follow-up). We also want to disable
dependenciesInfo for projects that we do not publish, users only care
about licenses they might be exposed to if they use our assembled
products. With all of the changes in this commit we have eliminated all
unknown licenses. A follow-up will enforce that when we add a new
dependency it does not get mapped to unknown, these will be forbidden in
the future. Therefore, with this change and earlier changes are left
having no unknown licenses and two custom licenses; custom here means it
does not map to an SPDX license type. Those two licenses are xz and
ldapsdk. A future change will not allow additional custom licenses
unless they are explicitly whitelisted. This ensures that if a new
dependency is added it is mapped to an SPDX license or mapped to custom
because it does not have an SPDX license.
* Fully encapsulate LocalCheckpointTracker inside of the engine

This is related to #27260. This commit combines the AcceptingSelector
and SocketSelector classes into a single NioSelector. This change
allows the same selector to handle both server and socket channels. This
is valuable as we do not necessarily want a dedicated thread running for
accepting channels.
With this change, this commit removes the configuration for dedicated
accepting selectors for the normal transport class. The accepting
workload for new node connections is likely low, meaning that there is
no need to dedicate a thread to this process.
This commit adds a new writeBlobAtomic() method to the BlobContainer
interface that can be implemented by repository implementations which

When the BlobContainer implementation does not provide a specific
implementation of writeBlobAtomic(), then the writeBlob() method is used.

ObjectParser should throw XContentParseExceptions, not IAE. A dedicated parsing

Closes#30605
With #31020 we introduced the ability for transport clients to indicate what features they support
in order to make sure we don't serialize object to them they don't support. This PR adapts the
serialization logic of persistent tasks to be aware of those features and not serialize tasks that
aren't supported.
Also, a version check is added for the future where we may add new tasks implementations and
need to be able to indicate they shouldn't be serialized both to nodes and clients.
As the implementation relies on the interface of `PersistentTaskParams`, these are no longer
optional. That's acceptable as all current implementation have them and we plan to make
`PersistentTaskParams` more central in the future.
Relates to #30731
This commit introduces the ability for a client to communicate to the
server features that it can support and for these features to be used in
influencing the decisions that the server makes when communicating with
the client. To this end we carry the features from the client to the
underlying stream as we carry the version of the client today. This
enables us to enhance the logic where we make protocol decisions on the
basis of the version on the stream to also make protocol decisions on
the basis of the features on the stream. With such functionality, the
client can communicate to the server if it is a transport client, or if
it has, for example, X-Pack installed. This enables us to support
rolling upgrades from the OSS distribution to the default distribution
without breaking client connectivity as we can now elect to serialize
customs in the cluster state depending on whether or not the client
reports to us using the feature capabilities that it can under these
customs. This means that we would avoid sending a client pieces of the
cluster state that it can not understand. However, we want to take care
and always send the full cluster state during node-to-node communication
as otherwise we would end up with different understanding of what is in
the cluster state across nodes depending on which features they reported
to have. This is why when deciding whether or not to write out a custom
we always send the custom if the client is not a transport client and
otherwise do not send the custom if the client is transport client that
does not report to have the feature required by the custom.

This change adds an option named `split_queries_on_whitespace` to the `keyword`
field type. When set to true full text queries (`match`, `multi_match`, `query_string`, ...) that target the field will split the input on whitespace to build the query terms. Defaults to `false`.
Closes#30393
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 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.
Include size of snapshot in snapshot metadata
Adds difference of number of files (and file sizes) between prev and current snapshot. Total number/size reflects total number/size of files in snapshot.
Closes#18543
Currently nio and netty modules use the CompletableFuture class for
managing listeners. This is unfortunate as that class accepts
Throwable. This commit adds a class CompletableContext that wraps
the CompletableFuture but does not accept Throwable. This allows the
modification of netty and nio logic to no longer handle Throwable.
Today, the `ClusterApplier` and `MasterService` both use the
`ClusterStateTaskListener` interface to notify their callers when asynchronous
activities have completed. However, this is not wholly appropriate: none of the
callers into the `ClusterApplier` care about the `ClusterState` arguments that
they receive. This change introduces a dedicated ClusterApplyListener
interface for callers into the `ClusterApplier`, to distinguish these listeners
from the real `ClusterStateTaskListener`s that are waiting for responses from
the `MasterService`.
This commit reintroduces 31251c9 and 63a5799. These commits introduced a
memory leak and were reverted. This commit brings those commits back
and fixes the memory leak by removing unnecessary retain method calls.
This reverts commit 31251c9 introduced in #30695.
We suspect this commit is causing the OOME's reported in #30811 and we will use this PR to test this assertion.
When doing a node restart using the test framework, the restarted node does not only use the
settings provided to the original node, but also additional settings provided by plugin extensions,
which does not correspond to the settings that a node would have on a true restart.
This is related to #29500. We are removing the ability to disable http
pipelining. This PR removes the references to disabling pipelining in
the integration test case.
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).
The new snapshot includes LUCENE-8324 which fixes missing checkpoint
after a fully deletes segment is dropped on flush. This snapshot should
resolves failed tests in the CorruptedFileIT suite.

This is related to #29500 and #28898. This commit removes the abilitiy
to disable http pipelining. After this commit, any elasticsearch node
will support pipelined requests from a client. Additionally, it extracts
some of the http pipelining work to the server module. This extracted
work is used to implement pipelining for the nio plugin.
This is related to #27260. The elasticsearch-nio jar is supposed to be
a library opposed to a framework. Currently it internally logs certain
exceptions. This commit modifies it to not rely on logging. Instead
exception handlers are passed by the applications that use the jar.
Meta plugins existed only for a short time, in order to enable breaking
up x-pack into multiple plugins. However, now that x-pack is no longer
installed as a plugin, the need for them has disappeared. This commit
removes the meta plugins infrastructure.
Date histograms on non-fixed timezones such as `Europe/Paris` proved much slower
than histograms on fixed timezones in #28727. This change mitigates the issue by
using a fixed time zone instead when shard data doesn't cross a transition so
that all timestamps share the same fixed offset. This should be a common case
with daily indices.
NOTE: Rewriting the aggregation doesn't work since the timezone is then also
used on the coordinating node to create empty buckets, which might be out of the
range of data that exists on the shard.
NOTE: In order to be able to get a shard context in the tests, I reused code
from the base query test case by creating a new parent test case for both
queries and aggregations: `AbstractBuilderTestCase`.
Mitigates #28727
This pipeline aggregation gives the user the ability to script functions that "move" across a window
of data, instead of single data points. It is the scripted version of MovingAvg pipeline agg.
Through custom script contexts, we expose a number of convenience methods:
- MovingFunctions.max()
- MovingFunctions.min()
- MovingFunctions.sum()
- MovingFunctions.unweightedAvg()
- MovingFunctions.linearWeightedAvg()
- MovingFunctions.ewma()
- MovingFunctions.holt()
- MovingFunctions.holtWinters()
- MovingFunctions.stdDev()
The user can also define any arbitrary logic via their own scripting, or combine with the above methods.
This change adds a `listTasks` method to the high level java
ClusterClient which allows listing running tasks through the
task management API.

A 6.x node can send a deprecation message that the default number of
shards will change from five to one in 7.0.0. In a mixed cluster,
whether or not a create index request sees five or one shard and
produces a deprecation message depends on the version of the master
node. This means that during BWC tests a test can see this deprecation
message depending on the version of the master node. In 6.x when we
introduced this deprecation message we assumed that whereever we see
this deprecation message is expected. However, in a mixed cluster test
we need a similar mechanism but it would only apply if the version of
the master node is earlier than 7.0.0. This commit takes advantage of a
recent change to expose the version of the master node to do sections of
REST tests. With this in hand, we can skip asserting on the deprecation
message if the version of the master node is before 7.0.0 and otherwise
seeing that deprecation message would be completely unexpected.
This commit is related to #28898. It adds an nio driven http server
transport. Currently it only supports basic http features. Cors,
pipeling, and read timeouts will need to be added in future PRs.
