This change was reverted after it caused random test failures. This was
due to a copy/paste error in the original PR which caused the mock
version of ClusterInfoService to be used whenever the mock *ZenPing* was
used, and the real ClusterInfoService to be used when MockZenPing was
not used.
Currently, pending operations can complete after tests with disruption scheme
completes. This commit waits for the pending operation counter to complete
after the tests are run
* Allows for an array of index template patterns to be provided to an

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.

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
as well as a BWC break in `OsStats.java`
The network disruption type "network delay" continues delaying existing requests even after the disruption has been cleared. This commit ensures that the requests get to execute right after the delay rule is cleared.
This commit fixes responses to HEAD requests so that the value of the
Content-Length is correct per the HTTP spec. Namely, the value of this
header should be equal to the Content-Length if the request were not a
HEAD request.
This commit also fixes a memory leak on HEAD requests to the main action
that arose from the bytes on a builder not being released due to them
being dropped on the floor to ensure that the response to the main
action did not have a body.
Relates #21123
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.
Closes#20763
Today we throw an assertion error if we release an AbstractArray more than once.
Yet, it's recommended to implement close methods such that they can be invoked
more than once. Guaranteed single release calls are hard to implement and some
situations might not be tested causing for instance `CircuitBreaker` to operate on
corrupted memory stats.
UpdateHelper, MetaDataIndexUpgradeService, and some recovery
stuff.
Move ClusterSettings to nullable ctor parameter of TransportService
so it isn't forgotten.
This change proposes the removal of all non-tcp transport implementations. The
mock transport can be used by default to run tests instead of local transport that has
roughly the same performance compared to TCP or at least not noticeably slower.
This is a master only change, deprecation notice in 5.x will be committed as a
separate change.
