Today a doc values update creates a new field infos file that contains the original field infos updated for the new generation as well as the new fields created by the doc values update.
However existing fields are cloned through the global fields (shared in the index writer) instead of the local ones (present in the segment).
In practice this is not an issue since field numbers are shared between segments created by the same index writer.
But this assumption doesn't hold for segments created by different writers and added through IndexWriter#addIndexes(Directory).
In this case, the field number of the same field can differ between segments so any doc values update can corrupt the index
by assigning the wrong field number to an existing field in the next generation.
When this happens, queries and merges can access wrong fields without throwing any error, leading to a silent corruption in the index.
This change ensures that we preserve local field numbers when creating
a new field infos generation.
ASF Release Policy states that we cannot have binary JAR files checked
in to our source releases, a few other projects have solved this by
modifying their generated gradlew scripts to download a copy of the
wrapper jar.
We now have a version and checksum file in ./gradle/wrapper directory
used for verifying the wrapper jar, and will take advantage of single
source java execution to verify and download.
The gradle wrapper jar will continue to be available in the git
repository, but will be excluded from src tarball generation. This
should not change workflows for any users, since we expect the gradlew
script to get the jar when it is missing.

This commit introduces a mechanism to control allocation of threads to slices planned for a query.
The default implementation uses the size of backlog queue of the executor to determine if a slice should be allocated a new thread
* Remove CurrentCoreDescriptorProvider
Replace `CurrentCoreDescriptorProvider` with a functional interface so
that it is easier to construct since all implementations in our code
base were anonymous classes anyway. Added Javadocs explaining the
usage instead of relying on class name to convey information.
Makes collections available sooner and reduces leaderVoteWait timeouts in large SolrCloud clusters.
This fixes a previous attempt to do this.
Fixes#1366
* add expressible support to list, and add example of removing a component
* document actions that can be passed to the /stream request handler
* responding to content feedback
* TestJsonFacet split into 3 classes, TestsJsonFacets, TestJsonFacetErrors
and TestJsonRangeFacet
* TestJsonFacets contains mainly terms faceting and stats
* range facet covers distributed cases too
