Some AbstractDisruptionTestCase tests start failing since we enabled
assertSeqNos (in #33130). They fail because the assertSeqNos assertion
queries cluster stats while the cluster is disrupted or not formed yet.
This commit switches to use the cluster state and shard stats directly
from the test cluster.
Closes#33251
This commit checks that when we manually add a class to
the codebase map, that it does in-fact not exist on the classpath
in a jar. This will only be true if we are using the test framework
externally such as when a user develops a plugin.
We generate slightly different NoOps in InternalEngine and
TransportShardBulkAction for the same failure.
1. InternalEngine uses Exception#getFailure to generate a message
without the class name: newOp [NoOp{seqNo=1, primaryTerm=1,
reason='Contexts are mandatory in context enabled completion field
[suggest_context]'}].
2. TransportShardBulkAction uses Exception#toString to generate a
message with the class name: NoOp{seqNo=1, primaryTerm=1,
reason='java.lang.IllegalArgumentException: Contexts are mandatory in
context enabled completion field [suggest_context]'}.
If a write operation fails while a replica is recovering, that replica
will possibly receive two different NoOps: one from recovery and one
from replication. These two different NoOps will trip
TranslogWriter#assertNoSeqNumberConflict assertion.
This commit ensures that we generate the same Noop for the same failure.
Closes#32986
This adds support for connecting to a remote cluster through
a tcp proxy. A remote cluster can configured with an additional
`search.remote.$clustername.proxy` setting. This proxy will be used
to connect to remote nodes for every node connection established.
We still try to sniff the remote clsuter and connect to nodes directly
through the proxy which has to support some kind of routing to these nodes.
Yet, this routing mechanism requires the handshake request to include some
kind of information where to route to which is not yet implemented. The effort
to use the hostname and an optional node attribute for routing is tracked
in #32517Closes#31840
If a shard was closed, we return null for SeqNoStats. Therefore the
assertion assertSeqNos will hit NPE when it verifies a closed shard.
This commit skips closed shards in assertSeqNos and enables this
assertion in AbstractDisruptionTestCase.
This commit adds a hook to AbstractSerializingTestCase to enable
skipping asserting that the x-content of the test instance and an
instance parsed from the x-content of the test instance are the
same. While we usually expect these to be the same, they will not be the
same when exceptions are involved because the x-content there is lossy.
* `foobar.txGet()` appears to return before `serviceB.stop()` returns, causing `ServiceB.close()` to run concurrently with the `stop` call and running into a race codition
* Closes#32863
We used to set `maxScore` to `0` within `TopDocs` in situations where there is really no score as the size was set to `0` and scores were not even tracked. In such scenarios, `Float.Nan` is more appropriate, which gets converted to `max_score: null` on the REST layer. That's also more consistent with lucene which set `maxScore` to `Float.Nan` when merging empty `TopDocs` (see `TopDocs#merge`).
This change allows an engine to recover from its local translog up to
the given seqno. The extended API can be used in these use cases:
When a replica starts following a new primary, it resets its index to
the safe commit, then replays its local translog up to the current
global checkpoint (see #32867).
When a replica starts a peer-recovery, it can initialize the
start_sequence_number to the persisted global checkpoint instead of the
local checkpoint of the safe commit. A replica will then replay its
local translog up to that global checkpoint before accepting remote
translog from the primary. This change will increase the chance of
operation-based recovery. I will make this in a follow-up.

Today, CapturingTransport#createCapturingTransportService creates a transport
service with a connection manager with reasonable default behaviours, but
overriding this behaviour in a consumer is a litle tricky. Additionally, the
default behaviour for opening a connection duplicates the content of the
CapturingTransport#openConnection() method.
This change removes this duplication by delegating to openConnection() and
introduces overridable nodeConnected() and onSendRequest() methods so that
consumers can alter this behaviour more easily.
Relates #32246 in which we test the mechanisms for opening connections to
unknown (and possibly unreachable) nodes.
This change introduces a dedicated ConnectionManager for every RemoteClusterConnection
such that there is not state shared with the TransportService internal ConnectionManager.
All connections to a remote cluster are isolated from the TransportService but still uses
the TransportService and it's internal properties like the Transport, tracing and internal
listener actions on disconnects etc.
This allows a remote cluster connection to have a different lifecycle than a local cluster connection,
also local discovery code doesn't get notified if there is a disconnect on from a remote cluster and
each connection can use it's own dedicated connection profile which allows to have a reduced set of
connections per cluster without conflicting with the local cluster.
Closes#31835
This is related to #32517. This commit passes the DiscoveryNode to the
initiateChannel method for different Transport implementation. This
will allow additional attributes (besides just the socket address) to be
used when opening channels.
This is a followup to #31886. After that commit the
TransportConnectionListener had to be propogated to both the
Transport and the ConnectionManager. This commit moves that listener
to completely live in the ConnectionManager. The request and response
related methods are moved to a TransportMessageListener. That listener
continues to live in the Transport class.
This is related to #31835. It moves the default connection profile into
the ConnectionManager class. The will allow us to have different
connection managers with different profiles.
This removes custom Response classes that extend `AcknowledgedResponse` and do nothing, these classes are not needed and we can directly use the non-abstract super-class instead.
While this appears to be a large PR, no code has actually changed, only class names have been changed and entire classes removed.
This commit fixes existing uses of forbidden apis in the test framework
and re-enables the forbidden apis check. It was previously completely
disabled and had missed a rename of the forbidden apis signatures files.
closes#32772
This is related to #31835. This commit adds a connection manager that
manages client connections to other nodes. This means that the
TcpTransport no longer maintains a map of nodes that it is connected
to.
Our rest testing framework has support for sniffing the host metadata on
startup and, before this change, it'd sniff that metadata before running
the first test. This prevents running these tests against
elasticsearch installations that won't support sniffing like Elastic
Cloud. This change allows tests to only sniff for metadata when they
encounter a test with a `node_selector`. These selectors are the things
that need the metadata anyway and they are super rare. Tests that use
these won't be able to run against installations that don't support
sniffing but we can just skip them. In the case of Elastic Cloud, these
tests were never going to work against Elastic Cloud anyway.
Currently AbstractBuilderTestCase generates certain random values in its
`beforeTest()` method annotated with @Before only the first time that a test
method in the suite is run while initializing the serviceHolder that we use for
the rest of the test. This changes the values of subsequent random values
and has the effect that when running single methods from a test suite with
"-Dtests.method=*", the random values it sees are different from when the same
test method is run as part of the whole test suite. This makes it hard to use
the reproduction lines logged on failure.
This change runs the inialization of the serviceHolder and the randomization
connected to it using the test runners master seed, so reproduction by running
just one method is possible again.
Closes#32400
Processing bulk request goes item by item. Sometimes during processing, we need to stop execution and wait for a new mapping update to be processed by the node. This is currently achieved by throwing a `RetryOnPrimaryException`, which is caught higher up. When the exception is caught, we wait for the next cluster state to arrive and process the request again. Sadly this is a problem because all operations that were already done until the mapping change was required are applied again and get new sequence numbers. This in turn means that the previously issued sequence numbers are never replicated to the replicas. That causes the local checkpoint of those shards to be stuck and with it all the seq# based infrastructure.
This commit refactors how we deal with retries with the goal of removing `RetryOnPrimaryException` and `RetryOnReplicaException` (not done yet). It achieves so by introducing a class `BulkPrimaryExecutionContext` that is used the capture the execution state and allows continuing from where the execution stopped. The class also formalizes the steps each item has to go through:
1) A translation phase for updates
2) Execution phase (always index/delete)
3) Waiting for a mapping update to come in, if needed
4) Requires a retry (for updates and cases where the mapping are still not available after the put mapping call returns)
5) A finalization phase which allows updates to the index/delete result to an update result.

It will be useful for future efforts to know if the global checkpoint
was updated. To this end, we need to expose whether or not the global
checkpoint was updated when the state of the replication tracker
updates. For this, we add to the tracker a callback that is invoked
whenever the global checkpoint is updated. For primaries this will be
invoked when the computed global checkpoint is updated based on state
changes to the tracker. For replicas this will be invoked when the local
knowledge of the global checkpoint is advanced from the primary.
The MockNioTransport (similar to the MockTcpTransport) is used for integ
tests. The MockTcpTransport has always only opened a single for all of
its work. The MockNioTransport has awlays opened the default number of
connections (13). This means that every test where two transports
connect requires 26 connections. This is more than is necessary. This
commit modifies the MockNioTransport to only require 3 connections.
We've recently seen a number of test failures that tripped an assertion in IndexShard (see issues
linked below), leading to the discovery of a race between resetting a replica when it learns about a
higher term and when the same replica is promoted to primary. This commit fixes the race by
distinguishing between a cluster state primary term (called pendingPrimaryTerm) and a shard-level
operation term. The former is set during the cluster state update or when a replica learns about a
new primary. The latter is only incremented under the operation block, which can happen in a
delayed fashion. It also solves the issue where a replica that's still adjusting to the new term
receives a cluster state update that promotes it to primary, which can happen in the situation of
multiple nodes being shut down in short succession. In that case, the cluster state update thread
would call `asyncBlockOperations` in `updateShardState`, which in turn would throw an exception
as blocking permits is not allowed while an ongoing block is in place, subsequently failing the shard.
This commit therefore extends the IndexShardOperationPermits to allow it to queue multiple blocks
(which will all take precedence over operations acquiring permits). Finally, it also moves the primary
activation of the replication tracker under the operation block, so that the actual transition to
primary only happens under the operation block.

This change updates KerberosAuthenticationIT to resolve the host used
to connect to the test cluster. This is needed because the host could
be an IP address but SPNEGO requires a hostname to work properly. This
is done by adding a hook in ESRestTestCase for building the HttpHost
from the host and port.
Additionally, the project now specifies the IPv4 loopback address as
the http host. This is done because we need to be able to resolve the
address used for the HTTP transport before the node starts up, but the
http.ports file is not written until the node is started.
Closes#32498
First, some background: we have 15 different methods to get a logger in
Elasticsearch but they can be broken down into three broad categories
based on what information is provided when building the logger.
Just a class like:
```
private static final Logger logger = ESLoggerFactory.getLogger(ActionModule.class);
```
or:
```
protected final Logger logger = Loggers.getLogger(getClass());
```
The class and settings:
```
this.logger = Loggers.getLogger(getClass(), settings);
```
Or more information like:
```
Loggers.getLogger("index.store.deletes", settings, shardId)
```
The goal of the "class and settings" variant is to attach the node name
to the logger. Because we don't always have the settings available, we
often use the "just a class" variant and get loggers without node names
attached. There isn't any real consistency here. Some loggers get the
node name because it is convenient and some do not.
This change makes the node name available to all loggers all the time.
Almost. There are some caveats are testing that I'll get to. But in
*production* code the node name is node available to all loggers. This
means we can stop using the "class and settings" variants to fetch
loggers which was the real goal here, but a pleasant side effect is that
the ndoe name is now consitent on every log line and optional by editing
the logging pattern. This is all powered by setting the node name
statically on a logging formatter very early in initialization.
Now to tests: tests can't set the node name statically because
subclasses of `ESIntegTestCase` run many nodes in the same jvm, even in
the same class loader. Also, lots of tests don't run with a real node so
they don't *have* a node name at all. To support multiple nodes in the
same JVM tests suss out the node name from the thread name which works
surprisingly well and easy to test in a nice way. For those threads
that are not part of an `ESIntegTestCase` node we stick whatever useful
information we can get form the thread name in the place of the node
name. This allows us to keep the logger format consistent.
`GetResult` and `SearchHit` have been adjusted to parse back the `_ignored` meta field whenever it gets printed out. Expanded the existing tests to make sure this is covered. Fixed also a small problem around highlighted fields in `SearchHitTests`.
This commit changes the randomization to always create an index with a type.
It also adds a way to create a query shard context that maps to an index with
no type registered in order to explicitely test cases where there is no type.
Today we allow plugins to add index store implementations yet we are not
doing this in our new way of managing plugins as pull versus push. That
is, today we still allow plugins to push index store providers via an on
index module call where they can turn around and add an index
store. Aside from being inconsistent with how we manage plugins today
where we would look to pull such implementations from plugins at node
creation time, it also means that we do not know at a top-level (for
example, in the indices service) which index stores are available. This
commit addresses this by adding a dedicated plugin type for index store
plugins, removing the index module hook for adding index stores, and by
aggregating these into the top-level of the indices service.
This commit introduces "Application Privileges" to the X-Pack security
model.
Application Privileges are managed within Elasticsearch, and can be
tested with the _has_privileges API, but do not grant access to any
actions or resources within Elasticsearch. Their purpose is to allow
applications outside of Elasticsearch to represent and store their own
privileges model within Elasticsearch roles.
Access to manage application privileges is handled in a new way that
grants permission to specific application names only. This lays the
foundation for more OLS on cluster privileges, which is implemented by
allowing a cluster permission to inspect not just the action being
executed, but also the request to which the action is applied.
To support this, a "conditional cluster privilege" is introduced, which
is like the existing cluster privilege, except that it has a Predicate
over the request as well as over the action name.
Specifically, this adds
- GET/PUT/DELETE actions for defining application level privileges
- application privileges in role definitions
- application privileges in the has_privileges API
- changes to the cluster permission class to support checking of request
objects
- a new "global" element on role definition to provide cluster object
level security (only for manage application privileges)
- changes to `kibana_user`, `kibana_dashboard_only_user` and
`kibana_system` roles to use and manage application privileges
