Today we can easily join a cluster that holds an index we don't support since
we currently allow rolling upgrades from 5.x to 6.x. Along the same lines we don't check if we can support an index based on the nodes in the cluster when we open, restore or metadata-upgrade and index. This commit adds
additional safety that fails cluster state validation, open, restore and /or upgrade if there is an open index with an incompatible index version created in the cluster.

Currently we have these logs for integration tests only.
This adds the following log at the start:
```
logger.info("[{}]: before test", getTestName());
```
and this is logged at the end, but before any clean up done in sub classes
```
logger.info("[{}]: after test", getTestName());
```
For the record, I also had to remove the geo-hash cell and geo-distance range
queries to make the code compile. These queries already throw an exception in
all cases with 5.x indices, so that does not hurt any more.
I also had to rename all 2.x bwc indices from `index-${version}` to
`unsupported-${version}` to make `OldIndexBackwardCompatibilityIT`
happy.
Lucene 6.2 added index and query support for numeric ranges. This commit adds a new RangeFieldMapper for indexing numeric (int, long, float, double) and date ranges and creating appropriate range and term queries. The design is similar to NumericFieldMapper in that it uses a RangeType enumerator for implementing the logic specific to each type. The following range types are supported by this field mapper: int_range, float_range, long_range, double_range, date_range.
Lucene does not provide a DocValue field specific to RangeField types so the RangeFieldMapper implements a CustomRangeDocValuesField for handling doc value support.
When executing a Range query over a Range field, the RangeQueryBuilder has been enhanced to accept a new relation parameter for defining the type of query as one of: WITHIN, CONTAINS, INTERSECTS. This provides support for finding all ranges that are related to a specific range in a desired way. As with other spatial queries, DISJOINT can be achieved as a MUST_NOT of an INTERSECTS query.
The Transport#connectToNodeLight concepts is confusing and not very flexible.
neither really testable on a unittest level. This commit cleans up the code used
to connect to nodes and simplifies transport implementations to share more code.
This also allows to connect to nodes with custom profiles if needed, for instance
future improvements can be added to connect to/from nodes that are non-data nodes without
dedicated bulks and recovery connections.
In the past we ran yaml tests against an internal cluster, which would get restarted after each test failure, hence the client objects needed to eventually be refreshed before each test. That is why we had the initClient method to re-initialize the YamlTestClient in the execution context. We ended up though re-initializing the client unconditionally, which is not needed.
Also, ESRestTestCase recreates the RestClient against the external cluster before each test, which is not needed given that nothing changes in the external cluster.
This commit removes the initClient method from the yaml tests execution context. The YamlTestClient can be eagerly created before the first yaml test runs and then re-used in subsequent tests. Also api calls to check for nodes versions etc. are moved out of YamlTestClient to ESClientYamlSuiteTestCase. Also the RestClient is now initialized in ESRestTestCase before the first test runs, and kept around afterwards as a static member.
Basically each subclass of EsRestTestCase will have its own RestClient instance, but the client will be shared across the different tests within the same class. The yaml test suite is just a special suite, composed of 600+ tests that are loaded from files, which will share the same client instance.
This change should speed tests up as well, as we don't recreate the RestClient before each single test, and we don't call _cat/nodes either before each single test.
TransportAddress used to be customizable per transport but this has been removed
a while ago. Therefore we can remove all usage of this method as well.

The disruption type LongGCDisruption simulates GCs on a node by suspending all the threads of that node. If the suspended threads are in a code section with shared JVM locks, however, it can prevent the other nodes from doing their thing. The class LongGCDisruption has a list of class names for which we know that this can occur. Whenever a test using the GC disruption type fails in mysterious ways, it becomes a long guessing game to find the offending class. This commit adds code to LongGCDisruption to automatically detect these situations, fail the test early and report the offending class and all relevant context.
Today when handling unreleased versions for backwards compatilibity
support, we scatted version constants across the code base and add some
asserts to support removing these constants when the version in question
is actually released. This commit improves this situation, enabling us
to just add a single unreleased version constant that can be renamed
when the version is actually released. This should make maintenance of
these versions simpler.

Today there is no way to get notified if a node is disconnected. Client code
must poll the TransportClient constantly to detect that a node is not connected
anymore in order to react and add new nodes or notify altering etc. For instance
if a hostname gets resolved to an IP but that host is disconnected clients want
to reconnect by resolving the hostname again which is a common situation in cloud
environments.
Closes#21424
Today we eagerly resolve unicast hosts. This means that if DNS changes,
we will never find the host at the new address. Moreover, a single host
failng to resolve causes startup to abort. This commit introduces lazy
resolution of unicast hosts. If a DNS entry changes, there is an
opportunity for the host to be discovered. Note that under the Java
security manager, there is a default positive cache of infinity for
resolved hosts; this means that if a user does want to operate in an
environment where DNS can change, they must adjust
networkaddress.cache.ttl in their security policy. And if a host fails
to resolve, we warn log the hostname but continue pinging other
configured hosts.
When doing DNS resolutions for unicast hostnames, we wait until the DNS
lookups timeout. This appears to be forty-five seconds on modern JVMs,
and it is not configurable. If we do these serially, the cluster can be
blocked during ping for a lengthy period of time. This commit introduces
doing the DNS lookups in parallel, and adds a user-configurable timeout
for these lookups.

* Add support for merging custom meta data in tribe node
Currently, when any underlying cluster has custom metadata
(via plugin), tribe node does not store custom meta data in its
cluster state. This is because the tribe node has no idea how to
select the appropriate custom metadata from one or many custom
metadata (corresponding to the number of underlying clusters).
This change adds an interface that custom metadata implementations
can extend to add support for merging mulitple custom metadata of
the same type for storing in the tribe state.

There have been reports that the query cache did not manage to speed up search
requests when the query includes a large number of different sub queries since
a single request may manage to exhaust the whole history (256 queries) while
the query cache only starts caching queries once they appear multiple times in
the history (#16031). On the other hand, increasing the size of the query cache
is a bit controversial (#20116) so this pull request proposes a different
approach that consists of never caching term queries, and not adding them to the
history of queries either. The reasoning is that these queries should be fast
anyway, regardless of caching, so taking them out of the equation should not
cause any slow down. On the other hand, the fact that they are not added to the
cache history anymore means that other queries have greater chances of being
cached.
#20960 removed `LocalDiscovery` and we now use `ZenDiscovery` in all our tests. To keep cluster forming fast, we are using a `MockZenPing` implementation which uses static maps to return instant results making master election fast. Currently, we don't set `minimum_master_nodes` causing the occasional split brain when starting multiple nodes concurrently and their pinging is so fast that it misses the fact that one of the node has elected it self master. To solve this, `InternalTestCluster` is modified to behave like a true cluster and manage and set `minimum_master_nodes` correctly with every change to the number of nodes.
Tests that want to manage the settings themselves can opt out using a new `autoMinMasterNodes` parameter to the `ClusterScope` annotation.
Having `min_master_nodes` set means the started node may need to wait for other nodes to be started as well. To combat this, we set `discovery.initial_state_timeout` to `0` and wait for the cluster to form once all node have been started. Also, because a node may wait and ping while other nodes are started, `MockZenPing` is adapted to wait rather than busy-ping.
This changes adds a test discovery (which internally uses the existing
mock zenping by default). Having the mock the test framework selects be a discovery
greatly simplifies discovery setup (no more weird callback to a Node
method).
Today when a node starts, we create dynamic socket permissions based on
the configured HTTP ports and transport ports. If no ports are
configured, we use the default port ranges. When a tribe node starts, a
tribe node creates an internal node client for connecting to each remote
cluster. If neither an explicit HTTP port nor transport ports were
specified, the default port ranges are large enough for the tribe node
and its internal node clients. If an explicit HTTP port or transport
port was specified for the tribe node, then socket permissions for those
ports will be created, but not for the internal node clients. Whether
the internal node clients have explicit ports specified, or attempt to
bind within the default range, socket permissions for these will not
have been created and the internal node clients will hit a permissions
issue when attempting to bind. This commit addresses this issue by also
accounting for tribe nodes when creating the dynamic socket
permissions. Additionally, we add our first real integration test for
tribe nodes.
This commit enables real BWC testing against a 5.1 snapshot. All
REST tests plus rolling upgrade test now run against a mixed version
cross major version cluster.

When a node closes, we shutdown logging as the last statement. This
statement must be last lest any subsequent attempts to log will blow up
by running into security permissions. Yet, in the case of a tribe node
this isn't enough. The first internal tribe node to close will shutdown
logging, and subsequent node closes will blow up with the aforementioned
problem. This commit migrate the Log4j shutdown to occur as part of the
shutdown hook that closes the node, after all nodes have
closed. Consequently, we can remove a hack in the test infrastructure to
prevent Log4j shutdowns when internal test nodes close and instead just
register a single shutdown hook that runs when the test JVM exits.

We currently often use ensureGreen or ensureYellow to check whether the cluster is in a good state again after shutting down a node. With the change in #21092, however, it can happen that if the node that is stopped is the master node, another node will become master and publish a cluster state where it is master but where the node that was stopped hasn't been removed yet from the cluster state. It will only publish a second state thereafter where the old master is removed. If the ensureGreen/ensureYellow is timed just right, it will get to execute before the second cluster state update removing the old master and the condition ensureGreen / ensureYellow might not hold at that point anymore.
At one point in the past when moving out the rest tests from core to
their own subproject, we had multiple test classes which evenly split up
the tests to run. However, we simplified this and went back to a single
test runner to have better reproduceability in tests. This change
removes the remnants of that multiplexing support.
Adds support for `?slices=N` to reindex which automatically
parallelizes the process using parallel scrolls on `_uid`. Performance
testing sees a 3x performance improvement for simple docs
on decent hardware, maybe 30% performance improvement
for more complex docs. Still compelling, especially because
clusters should be able to get closer to the 3x than the 30%
number.
Closes#20624
Today if you start Elasticsearch with the status logger configured to
the warn level, or use a transport client with the default status logger
level, you will see warn messages about deprecation loggers being
created with different message factories and that formatting might be
broken. This happens because the deprecation logger is constructed using
the message factory from its parent, an artifact leftover from the first
Log4j 2 implementation that used a custom message factory. When that
custom message factory was removed, this constructor invocation should
have been changed to not explicitly use the message factory from the
parent. This commit fixes this invocation. However, we also had some
status checking to all tests to ensure that there are no warn status log
messages that might indicate a configuration problem with Log4j 2. These
assertions blow up badly without the fix for the deprecation logger
construction, and also caught a misconfiguration in one of the logging
tests.
Relates #21339
This is a bit funky to do with junit because we need per test state
but we only want to log it per suite. So we use a static flag that
we test per test and reset before every suite.
Our test infrastructure checks after running each test that there are no more in-flight requests on the shard level. Whenever the check fails, we only know that there were in-flight requests but don't know what requests were causing this issue. This commit adds the replication tasks that are still active at that moment to the assertion error.
Plugins: Remove pluggability of ZenPing
ZenPing is the part of zen discovery which knows how to ping nodes.
There is only one alternative implementation, which is just for testing.
This change removes the ability to add custom zen pings, and instead
hooks in the MockZenPing for tests through an overridden method in
MockNode. This also folds in the ZenPingService (which was really just a
single method) into ZenDiscovery, and removes the idea of having
multiple ZenPing instances. Finally, this was the last usage of the
ExtensionPoint classes, so that is also removed here.
This adds checks for expected warning headers to the query builder test
infrastructure. Tests that are adding deprecation warnings to the response
headers need to check those, otherwise the abstract base class for the test
class will complain at teardown.
Checks on static test state are run by an @After method in ESTestCase. Suite-scoped tests in ESIntegTestCase only shut down in an @AfterClass method, which executes after the @After method in ESTestCase. The suite-scoped cluster can thus still execute actions that will violate the checks in @After without those being caught. A subsequent test executing within the same JVM will fail these checks however when @After gets called for that test.
This commit adds an explicit call to check the static test state after the suite-scoped cluster has been shut down.
Today these two are considered mutual exclusive but they are not in
practice. For instance a mixed version cluster might not return a
given warning depending on which node we talk to but on the other hand
some runners might not even support warnings at all so the test might be
skipped either by version or by feature.
The `IndexService#newQueryShardContext()` method creates a QueryShardContext on
shard `0`, with a `null` reader and that uses `System.currentTimeMillis()` to
resolve `now`. This may hide bugs, since the shard id is sometimes used for
query parsing (it is used to salt random score generation in `function_score`),
passing a `null` reader disables query rewriting and for some use-cases, it is
simply not ok to rely on the current timestamp (eg. percolation). So this pull
request removes this method and instead requires that all call sites provide
these parameters explicitly.
Before publishing a cluster state the master connects to the nodes that are added in the cluster state. When publishing fails, however, it does not disconnect from these nodes, leaving NodeConnectionsService out of sync with the currently applied cluster state.
The `_cat/nodes` API might not be available in all clusters for instance
if they have authorization enabled. This change falls back to the previously
used method of using the '/' endpoint to fetch the nodes version, this is best
effort and will emit a warning.
Lucene 6.3 is expected to be released in the next weeks so it'd be good to give
it some integration testing. I had to upgrade randomized-testing too so that
both Lucene and Elasticsearch are on the same version.
Today we only use a single node to send requests to when we run REST tests.
In some cases we have more than one node (ie. in the BWC case) where we should
send requests to all nodes in a round-robin fashion. This change passes all
available node endpoints to the rest test.
Additionally, this change adds the setting of `discovery.zen.minimum_master_nodes`
to the cluster formation forcing the nodes to wait for all other nodes until the cluster
is formed. This allows for a more realistic master election and allows all master eligable
nodes to become master while before always the first node in the cluster became the master.
This also adds logging to each test run to log the master nodes version and the minimum node
version in the cluster to help debugging BWC test failures.
This fixes our cluster formation task to run REST tests against a mixed version cluster.
Yet, due to some limitations in our test framework `indices.rollover` tests are currently
disabled for the BWC case since they select the current master as the merge node which
happens to be a BWC node and we can't relocate all shards to it since the primaries are on
a higher version node. This will be fixed in a followup.
Closes#21142
Note: This has been cherry-picked from 5.0 and fixes several rest tests

Currently test that check that equals() and hashCode() are working as expected
for classes implementing them are quiet similar. This change moves common
assertions in this method to a common utility class. In addition, another common
utility function in most of these test classes that creates copies of input
object by running them through a StreamOutput and reading them back in, is moved
to ESTestCase so it can be shared across all these classes.
Closes#20629
Today the request interceptor can't support async calls since the response
of the async call would execute on a different thread ie. a client or listener
thread. This means in-turn that the intercepted handler is not executed with the
thread it was supposed to run and therefor can, if it's executing blocking
operations, potentially deadlock an entire server.
* Move all zen discovery classes into o.e.discovery.zen
This collapses sub packages of zen into zen. These all had just a couple
classes each, and there is really no reason to have the subpackages.
* fix checkstyle
`LocalDiscovery` is a discovery implementation that uses static in memory maps to keep track of current live nodes. This is used extensively in our tests in order to speed up cluster formation (i.e., shortcut the 3 second ping period used by `ZenDiscovery` by default). This is sad as that mean that most of the test run using a different discovery semantics than what is used in production. Instead of replacing the entire discovery logic, we can use a similar approach to only shortcut the pinging components.
During a recent merge from master, we lost the bridge from IndicesClusterStateService to the GlobalCheckpointService of primary shards, notifying them of changes to the current set of active/initializing shards. This commits add the bridge back (with unit tests). It also simplifies the GlobalCheckpoint tracking to use a simpler model (which makes use the fact that the global check point sync is done periodically).
The old integration CheckpointIT test is moved to IndexLevelReplicationTests. I also added similar assertions to RelocationsIT, which surfaced a bug in the primary relocation logic and how it plays with global checkpoint updates. The test is currently await-fixed and will be fixed in a follow up issue.
This commit changes the current REST API parser to make it fail and throw an exception when a REST specification file contains a duplicated parameters, or path, or method, or path part.
This is important to allow any test to use RandomQueryBuilder#createQuery()
since some of the query builders that are used in this test test the length
of the types array and otherwise will thow NPE if the test is not a subclass
of AbstractQueryTestCase.
The cache relies on the equals() method so we just need to make sure script
queries can never be equals, even to themselves in the case that a weight
is used to produce a Scorer on the same segment multiple times.

Today we throw an assertion error if we release an AbstractArray more than once.

Today SearchContext expose the current context as a thread local which makes any kind of sane interface design very very hard. This PR removes the thread local entirely and instead passes the relevant context anywhere needed. This simplifies state management dramatically and will allow for a much leaner SearchContext interface down the road.
LongGCDisruption suspends and resumes node threads but respects several
`unsafe` class name patterns where it's unsafe to suspend. For instance
log4j uses a global lock so we can't suspend a thread that is currently
calling into log4j. The same is true for the security manager, it's similar
to log4j a shared resource between the test and the node that is _suspended_.
This change adds `java.lang.SecrityManager` to the unsafe patterns.
This prevents test framework deadlocking if a nodes thread is supended
while it's calling into the security manager that uses synchronized maps etc.
today it's not possible to use date-math efficiently with the `_rollover`

The logging listener tests started failing after
953a8a959b when the tests are run with
tests.es.logger.level set to any level other than debug. This is because
these tests were based around the assumption that the default logging

default logging level via that system property. This commit fixes these
failing tests by adjusting this assumption to account for the fact that
the default logging level could be different.
Pipe in the `tests.es.logger.level` system property to the log4j config file used in tests. We still default to info. Also adapts the logger name to use the first letter of packages.
