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
Users wanting to send a request by providing only its method and endpoint, effectively the only two required arguments, shouldn't need to pass in an empty map and a null entity for the body. While at it we can also add a variant to send requests by specifying only method, endpoint and params, but not body. Headers remain a vararg as last argument, so they can always optionally be provided.
Closes#19312
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 commit adds a note to the GitHub issue template noting that bug
reports on OS that we do not support or feature requests for OS that we
do not support will be closed.

If there are percolator queries containing `range` queries with ranges based on the current time then this can lead to incorrect results if the `percolate` query gets cached. These ranges are changing each time the `percolate` query gets executed and if this query gets cached then the results will be based on how the range was at the time when the `percolate` query got cached.
The ExtractQueryTermsService has been renamed `QueryAnalyzer` and now only deals with analyzing the query (extracting terms and deciding if the entire query is a verified match) . The `PercolatorFieldMapper` is responsible for adding the right fields based on the analysis the `QueryAnalyzer` has performed, because this is highly dependent on the field mappings. Also the `PercolatorFieldMapper` is responsible for creating the percolate query.
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.
Today in the packaging removal scripts, we disable the service in
post-uninstall. Yet, this happens after service files have been
erased. On some systems, this can cause the service disable to fail
leaving behind state causing the service to be enabled on subsequent
installs. This commit moves the service disabling to the pre-uninstall
script to prevent this issue.

Repository plugins currently use a lot of custom classes like
RepositoryName and RepositorySettings in order to use guice to construct
repository implementations. But repositories now only really need their
settings to be constructed. Anything else they need (eg a cloud client)
can be constructed within the plugin, instead of via guice.
This change makes repository plugins use the new pull model. It removes
guice from the construction of Repository objects (no more child
injectors) and also from all repository plugins.
This exposes a method to start an action and return a task from
`NodeClient`. This allows reindex to use the injected `Client` rather
than require injecting `TransportAction`s
Today when a thread encounters a fatal unrecoverable error that
threatens the stability of the JVM, Elasticsearch marches on. This
includes out of memory errors, stack overflow errors and other errors
that leave the JVM in a questionable state. Instead, the Elasticsearch
JVM should die when these errors are encountered. This commit causes
this to be the case.

This commit migrates the Vagrant box for Fedora for the packaging tests
from Fedora 22 to Fedora 24 as Fedora 22 reached end-of-line upon the
release of Fedora 24.

The assumption is HostsSniffer is that all of the arguments have been properly provided and validated through HostsSniffer.Builder, except they weren't, as the scheme didn't have a default value and when not set would cause NPEs down the road. Improved tests to catch this also.
