It is possible to register multiple settings with complex matchers that could both match
a given key. The behavior when this occurs can lead to issues and depends on the
number of settings that have been registered. In order to identify the setting for a given
key, we iterate over the values in a map to find the first setting that matches the given key
and iteration order of a map should not be relied upon.
This commit checks complex settings when adding them and if the keys for these overlap,
an IllegalArgumentException is now thrown.
This commit works around an issue with hostname verification in HttpClient when using IPv6
addresses in URLs. When an IPv6 address is used in a URL it is typically wrapped with square
brackets. The hostname verifier for HttpClient does not recognize these as valid IPv6 addresses
and instead treats them as a DNS name. We wrap the strict hostname verifier for this version
of HttpClient and strip brackets if we need to.
The corresponding issue in HttpClient is https://issues.apache.org/jira/browse/HTTPCLIENT-1698
but the fix has not been released yet in a stable version.
We should open up the node to the world when it's as ready as possiblAt the moment we open up the transport service before the local node has been fully initialized. This causes bug as some data structures are not fully initialized yet. See for example #16723.
Sadly, we can't just start the TransportService last (as we do with the HTTP server) because the ClusterService needs to know the bound published network address for the local DiscoveryNode. This address can only be determined by actually binding (people may use, for example, port 0). Instead we start the TransportService as late as possible but block any incoming requests until the node has completed initialization.
A couple of other cleanup during start time:
1) The gateway service now starts before the initial cluster join so we can simplify the logic to recover state if the local node has become master.
2) The discovery is started before the transport service accepts requests, but we only start the join process later using a dedicated method.

This commit removes the system property "es.useLinkedTransferQueue" that
defaulted to false and was used to control the queue implementation used
in a few places.
Closes#16786
The extra config copy task for integ tests was previously overwriting
the source and destination for each file to be copied, leaving only the
last. This fixes it to create sub copy specs (which is what was
originally intended) for each file.
This commit adds a check on startup for G1 GC while running on early
versions of HotSpot version 25. This is to prevent potential data
corruption issues that can occur on those versions.
Closes#16737
Java NIO has the notion of gathering writes. These are writes that
gather data from multiple buffers into a single channel. These gathering
writes in Netty have been enabled by default with the possibility to
disable them using "es.netty.gathering". This flag was added in case
having gathering writes on by default did not work out. We have not
published this ability and sufficient time has passed to render
judgement that using gathering writes is okay.
Closes#16774
This commits adds an issue template for contributors that open bug
reports or feature requests.
Additionally, this commit adds a .github subdirectory to the project and
moves the CONTRIBUTING.md file to that directory.
Closes#16773
Expose http address in cat/nodes and cat/nodeattrs APIs
We expose a lot of information like IP address and port but never
expose the http address/ip:port in the CAT API. It's nice to have it
there too since otherwise json parsing is required to get this information

Elasticsearch should reject ids that are this long, to ensure a document
always remains retrievable for clients that impose a maximum URI length
