Today we assert that the tmp files are present but if the recovery
was canceled this might not be the case while still a valid state.
This chance only throws the AssertionError if the recovery is still active.
This moves all netty related code into modules/transport-netty the module is build as a zip file as well as a JAR to serve as a dependency for transport client. For the time being this is required otherwise we have no network based impl. for transport client users. This might be subject to change given that we move forward http client.
* Clean up the generics around significant terms aggregation results
* Reduce code duplicated between `SignificantLongTerms` and
`SignificantStringTerms` by creating `InternalMappedSignificantTerms`
and moving common things there where possible.
* Migrate to `NamedWriteable`
* Line length fixes while I was there
This commit removes support for properties syntax and config files:
- removed support for elasticsearch.properties
- removed support for logging.properties
- removed support for properties content detection in REST APIs
- removed support for properties content detection in Java API

Some tests still start http implicitly or miss configuring the transport clients correctly.
This commit fixes all remaining tests and adds a depdenceny to `transport-netty` from
`qa/smoke-test-http` and `modules/reindex` since they need an http server running on the nodes.
This also moves all required permissions for netty into it's module and out of core.
If a nested, has_child or has_parent query's inner query gets rewritten then the InnerHitBuilder should use that rewritten form too, otherwise this can cause exceptions in a later phase.
Also fixes a bug that HasChildQueryBuilder's rewrite method overwrites max_children with min_children value.
Closes#19353
That exception is currently serialized as its current base class IllegalStateException which confuses code supposed to deal with the stepping down of a master. This is an important exception and we should be able to serialize it correctly. This commit fixes it by moving the exception to inherit from ElasticsearchException and properly register it.
As a bonus I adapted CapturingTransport to properly simulate serialized exceptions.
Switches most search behavior extensions from push (`onModule(SearchModule)`)
to pull (`implements SearchPlugin`). This effort in general gives plugin
authors a much cleaner view of how to extend Elasticsearch and starts to
set up portions of Elasticsearch as "the plugin API". This commit in
particular does that for search-time behavior like customized suggesters,
highlighters, score functions, and significance heuristics.
It also switches most such customization to being done at search module
construction time which is much, much easier to reason about from a testing
perspective. It also helps significantly in the process of de-guice-ing
Elasticsearch's startup.
There are at least two major search time extensions that aren't covered in
this commit that will simply have to wait for the next commit on the topic
because this one has already grown large: custom aggregations and custom
queries. These will likely live in the same SearchPlugin interface as well.
This change adds a createComponents() method to Plugin implementations
which they can use to return already constructed componenents/services.
Eventually this should be just services ("components" don't really do
anything), but for now it allows any object so that preconstructed
instances by plugins can still be bound to guice. Over time we should
add basic services as arguments to this method, but for now I have left
it empty so as to not presume what is a necessary service.
this commit moves the most of the http related integ tests out into it's own
`qa/smoke-test-http` project where most of the test can run against the external cluster.
Today when a node is removed the cluster (it leaves or it fails), we
submit a cluster state update task. These cluster state update tasks are
processed serially on the master. When nodes are removed en masse (e.g.,
a rack is taken down or otherwise becomes unavailable), the master will
be slow to process these failures because of the resulting reroutes and
publishing of each subsequent cluster state. We improve this in this
commit by processing the node removals using the cluster state update
task batch processing framework.

Today we have a bunch of tests that use netty transport for several reasons
these tests use it because they need to run some tcp based transport. Yet, this
couples our tests tightly to the netty implementation which should be tested on it's own.
This change adds a plain socket based blocking TcpTransport implementation that is used by
default in tests if local transport is suppressed or if network is selected.
It also adds another tcp network implementation as a showcase how the interface works.
Lucene IndexWriter asserts on files existing on the filesystem but
some tests throw IOException explicitly on those operatiosn such that
some tests trip asserts. We had this before on InternalEngine#ctor
and added some logic there to catch only a specific assertions based
on some excepition stack analysis. This change applies the same logic
to the IndexWriter#commit part of the engine since it can hit the same
issue.
This also fixes a self-suppression issue in Store.java.
Closes#19356
Several tests required http.enabled where it was unnecessary.
We also had RestMainActionIT which tests what two of our REST tests
test already so I removed it.
The explicit use of http.enabled: false is also obsolet since our
test do that by default.
The DiscoveryNodeService exists to register CustomNodeAttributes which
plugins can add. This is not necessary, since plugins can already add
additional attributes, and use the node attributes prefix.
This change removes the DiscoveryNodeService, and converts the only
consumer, the ec2 discovery plugin, to add the ec2 availability zone
in additionalSettings().
This change removes the ability for guice to have child injectors (and
the entire concept of parent injectors) from our fork of guice. The
methodology for removing was simple: I removed createChildInjector, and
continued to remove methods and members that were unused until my head
was spinning. The motivation for this change is to limit what our fork
of guice gives us access to, so we don't regress and start adding back
more complicated uses.
This adds a test that uses transport implementation and sends random requests
to 3 different nodes, the request handlers maybe forwarding the requests to yet another node
etc. until returning the response. This test basically tests that nodes are not deadlocking
in a distributed fashion.
