With the recent change to allow ESSingleNodeTestCase to specify plugins
and Version for the node, node creation became lazy, where it now
happens before the first test to run. However, there were many static
methods on ESSingleNodeTestCase that still try to access the node. This
change makes those methods non-static.
This commit removes and forbids the use of lowercase ells ('l') in long
literals because they are often hard to distinguish from the digit
representing one ('1').
Closes#16329
We are leaking all kinds of resources if something during Node#close() barfs.
This commit cuts over to a list of closeables to release resources that
also closed remaining services if one or more services fail to close.
Closes#13685
In junit5, a neat assertion method is added which makes testing expected
failures a little more straightforward. The block of code that is
expected to throw is passed in with a lambda expression, and the caught
exception returned for inspection.
This change adds an implementation of expectThrows to ESTestCase. When
junit5 is eventually releassed and we switch to it, we can remove.
Now MasterNodeOperations, ReplicationAllShards, ReplicationSingleShard, BroadcastReplication and BroadcastByNode actions keep track of their parent tasks.
Note for many of the settings we had a netty specific override to a generic transport setting. I have removed those as they are not needed imo (ex. "transport.connections_per_node.recovery" was overriden by "transport.netty.connections_per_node.recovery", which I removed). The netty prefix was kept for settings that are tied to the netty universe - ex. "transport.netty.max_cumulation_buffer_capacity"
Closes#16200
In the early days Elasticsearch used to use the index name as the index identity. Around 1.0.0 we introduced a unique index uuid which is stored in the index setting. Since then we used that uuid in a few places but it is by far not the main identifier when working with indices, partially because it's not always readily available in all places.
This PR start to make a move in the direction of using uuids instead of name by making sure that the uuid is available on the Index class (currently just a wrapper around the name) and as such also available via ShardRouting and ShardId.
Note that this is by no means an attempt to do the right thing with the uuid in all places. In almost all places it falls back to the name based comparison that was done before. It is meant as a first step towards slowly improving the situation.
Closes#16217
This commit limits the `index.translog.sync_interval` to a value not less than `100ms` and
removes the support for fsync on every operation which used to be enabled if `index.translog.sync_interval` was set to `0s`
Now this pr also only schedules an async fsync if the durability is set to `async`. By default not async task is scheduled.
Closes#16152
This commit method renames the ScriptEngineService interface methods
types, extensions, and sandboxed to getTypes, getExtensions, and
isSandboxed, respectively.
This commit converts the script mode settings to the new settings
infrastructure. This is a major refactoring of the handling of script
mode settings. This refactoring is necessary because these settings are
determined at runtime based on the registered script engines and the
registered script contexts.
The search_after parameter provides a way to efficiently paginate from one page to the next. This parameter accepts an array of sort values, those values are then used by the searcher to sort the top hits from the first document that is greater to the sort values.
This parameter must be used in conjunction with the sort parameter, it must contain exactly the same number of values than the number of fields to sort on.
NOTE: A field with one unique value per document should be used as the last element of the sort specification. Otherwise the sort order for documents that have the same sort values would be undefined. The recommended way is to use the field `_uuid` which is certain to contain one unique value for each document.
Fixes#8192
When a Version is passed to `Settings#put(String, Version)` it's id is used as
an integer which should also be used to deserialize it on the consumer end.
Today AssertinLocalTransport expects Version#toString() to be used which can lead
to subtile bugs in tests.
This commit migrates all the settings under network service to the new settings infra.
It also adds some chaining utils to make fall back settings slightly less verbose.
Breaking (but I think acceptable) - network.tcp.no_delay and network.tcp.keep_alive used to accept the value `default` which make us not set them at all on netty. Our default was true so we weren't using this feature. I removed it and now we only accept a true boolean.
* `test.cluster.node.seed` was only used in one place where it wasn't adding value and was now replaced with a constant
* `tests.portsfile` is now an official setting and has been renamed to `node.portsfile`
this commit also convert `search.default_keep_alive` and `search.keep_alive_interval` to the new settings infrastrucutre
This commit allows an integ test to wrap all clients that are exposed by the
InternalTestCluster which is useful for request interception or to add general headers
to request or to intercept client to server call even if the client calls are done from within
the test framework.
This commit fixes an issue in the handling of TransportExceptions in
ShardStateAction. There were two cases not being handled correctly.
- when the local node is shutting down, handlers will be notified with
a TransportException with a message starting "transport stopped"
- when the remote node disconnects, handlers will be notified with a
NodeDisconnectedException
In both of these cases, the cause of the exception will be null and this
was incorrectly being handled. The first case can passed to the listener
like any other critical non-channel failure, and the second case can be
handled by modifying the logic for detecting master channel exceptions.
There was a third case of NodeNotConnectedException that was not being
treated as a master channel exception but should be.
This commit adds an integration test that simulates the handling of a
shard failure request during a network partition. By isolating the
master from the cluster while a shard failed request is in flight, this
test simulates that we wait until a new master is elected and then retry
sending that shard failed request to the newly elected master.
This commit adds methods to CapturingTransport to separate local and
remote transport exceptions. The motivation for this change is that
local transport exceptions are delivered to listeners (usually, but not
always) wrapped in SendRequestTransportException while remote transport
exceptions are delivered to listeners wrapped in
RemoteTransportException. By making this distinction clear in the
CapturingTransport, this makes it less likely that tests will make
incorrect assumptions about the exceptions coming out of the transport
layer to listeners.
Closes#16057
The rest test framework, because it used to be tightly integrated with
ESIntegTestCase, currently expects the addresses for the test cluster to
be passed using the transport protocol port. However, it only uses this
to then find the http address.
This change makes ESRestTestCase extend from ESTestCase instead of
ESIntegTestCase, and changes the sysprop used to tests.rest.cluster,
which now takes the http address.

We have two similar tests with the same name, ContextAndHeaderTransportTests.
They shared lots of common code so I extracted much of it into
ActionRecordingPlugin, a plugin which records all action requests for later
inspection.
I also removed all the warnings from both tests. That made lang-mustache
compile cleanly without any custom -Xlint so I removed those. To remove
the warnings I had to add type parameters to ActionFilter which seemed
like a good idea anyway.
The old infa has been removed in this commit such that nothing uses `DynamicSettings` anymore
and all index-scoped settings require to be registered before the node has fully started up.
Site plugins used to be used for things like kibana and marvel, but
there is no longer a need since kibana (and marvel as a kibana plugin)
uses node.js. This change removes site plugins, as well as the flag for
jvm plugins. Now all plugins are jvm plugins.
This undocumented setting was mainly used for testing and a safety net for
a new flushOnClose feature back in 1.x. We can now safely remove this setting.
The test usage now uses a mock plugin setting to achive the same.
Today we maintain a lot of settings on the shard level which are all index level settings.
In order to cut over to the new settings API where we register update listener we have to move
all of them on to the index level otherwise we need a way to un-register listeners which is error-prone
and requires additional handling when shards are closed. It's simpler and also more accurate to handle all of
them on the index level where we can trash the entire registry for update listener once the index goes out of scope.
ContextAndHeaders has a massive impact on the core infrastructure since it has to
be manually passed on to all relevant places across threads/network calls etc. For the same reason
it's also very error prone and easily forgotten on potentially relevant APIs.
The new ThreadContext is associated with a ThreadPool (node or transport client) and ensures that
headers and context registered on a current thread are inherited to new threads spawned, send across
the network to be deserialized on the receiver end as well as restored on the response handling thread
once the response is received.
This commit adds convenience methods to o.e.t.t.CapturingTransport
that enables capturing requests and clearing the captured requests
with a single method. This is to simplify a common pattern in tests of
capturing requests, and then clearing the captured requests.
1. Uses forbidden patterns to prevent things from referencing
java.io.Serializable or from mentioning serialVersionUID.
2. Uses -Xlint:-serial so we don't have to hear from javac that we aren't
declaring serialVersionUID on any classes that we make that happen to extend
Serializable.
3. Remove Serializable and serialVersionUID declarations.
I didn't use forbidden apis because it doesn't look like it has a way to ban
explicitly implementing Serializable. If you try to ban Serializable with
forbidden apis you end up banning all Exceptions and all Strings.
Closes#15847
This commit removes and now forbids use of
org.apache.lucene.index.IndexWriter#isLocked as this method was
deprecated in LUCENE-6508. The deprecation is due to the fact that
checking if a lock is held before acquiring that lock is subject to a
time-of-check-to-time-of-use race condition. There were three uses of
IndexWriter#isLocked in the code base:
- a logging statement in o.e.i.e.InternalEngine where we are already in
an exceptional condition that the lock was held; in this case,
logging whether or not the directory is locked is superfluous
- in o.e.c.l.u.VersionsTests where we were verifying that a write lock
is released upon closing an IndexWriter; in this case, the check is
not needed as successfully closing an IndexWriter releases its
write lock
- in o.e.t.s.MockFSDirectoryService where we were verifying that a
directory is not write-locked before (implicitly) trying to obtain
such a write lock in org.apache.lucene.index.CheckIndex#<init> (this
is the exact type of a situation that is subject to a race
condition); in this case we can proceed by just (implicitly) trying
to obtain the write lock and failing if we encounter a
LockObtainFailedException
