Removes all our logger wrappers except the wrapper for log4j1.2. If you
depend on Elasticsearch's jar in your application you'll need to declare
log4j 1.2 and/or some bridge to your favorite logger.
We did this to simplify our builds and code. No more commons-logging like
log implementation sniffing. No more optional dependency hacks in gradle.
We might one day want to use j.u.l instead of log4j. If we do want that
we can recover its wrapper by studying this commit. We didn't go directly
to j.u.l in this commit because that is a bigger change. Our logging
configuration is based on log4j1.2 and people are used to it. So it'd
be a much more fraught breaking change to do that conversion.
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.
Currently dynamic mappings propgate through call semantics, where deeper
dynamic mappings are merged into higher level mappings through
return values of recursive method calls. This makese it tricky
to handle multiple updates in the same method, for example when
trying to create parent object mappers dynamically for a field name
that contains dots.
This change makes the api for adding mappers a simple list
of new mappers, and moves construction of the root level mapping
update to the end of doc parsing.
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.

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.
