When we rollover and index we write the conditions of the rollover that
the old index met into the old index. Loading this index metadata
requires a working `NamedXContentRegistry` that has been populated with
parsers from the rollover infrastructure. We had a few loads that didn't
use a working `NamedXContentRegistry` and so would fail if they ever
encountered an index that had been rolled over. Here are the locations
of the loads and how I fixed them:
* IndexFolderUpgrader - removed entirely. It existed to support opening
indices made in Elasticsearch 2.x. Since we only need this change as far
back as 6.4.1 which will supports reading from indices created as far
back as 5.0.0 we should be good here.
* TransportNodesListGatewayStartedShards - wired the
`NamedXContentRegistry` into place.
* TransportNodesListShardStoreMetaData - wired the
`NamedXContentRegistry` into place.
* OldIndexUtils - removed entirely. It existed to support the zip based
index backwards compatibility tests which we've since replaced with code
that actually runs old versions of Elasticsearch.
In addition to fixing the actual problem I added full cluster restart
integration tests for rollover which would have caught this problem and
I added an extra assertion to IndexMetaData's deserialization code which
will trip if we try to deserialize and index's metadata without a fully
formed `NamedXContentRegistry`. It won't catch if use the *wrong*
`NamedXContentRegistry` but it is better than nothing.

In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `qa/full-cluster-restart` project to use the new
versions.
It also fixes a small bug in the test for explain on the `_all` field
that was causing it to not properly invoke `_explain`.
Merges the `query-builder-bwc` qa project into the
`full-cluster-restart` qa project, saving a cluster starts on every
build and *many* cluster starts on `./gradlew bwcTests`.
Although the master branch does not affect by #31482, it's helpful to
have BWC tests that verify the peer recovery with a synced-flush index.
This commit adds the bwc tests from #31506 to the master branch.

The test was using a parameter on GET /_cluster/health that older nodes
do not understand. Yet, we do no even need to make this call here, we
can use ensure green for the index.
This test is failing because of an addition of a call to GET
/_cluster/health with the parameter wait_for_no_initializing_shards set
to true. As older versions of Elasticsearch do not understand this
parameter, this request fails and the test fails. This commit marks this
test as awaiting a fix.
* Decouple XContentBuilder from BytesReference
This commit removes all mentions of `BytesReference` from `XContentBuilder`.
This is needed so that we can completely decouple the XContent code and move it
into its own dependency.
While this change appears large, it is due to two main changes, moving
`.bytes()` and `.string()` out of XContentBuilder itself into static methods
`BytesReference.bytes` and `Strings.toString` respectively. The rest of the
change is code reacting to these changes (the majority of it in tests).

Applying the rest test gradle plugin already uses the zip distribution
by default, so specifying it explicitly is not necessary. These are
leftovers from before zip was the default for rest tests.
Generalizing BWC building so that there is less code to modify for a release. This ensures we do not
need to think about what major or minor version is in the gradle code. It follows the general rules of the
elastic release structure. For more information on the rules, see the VersionCollection's javadoc.
This also removes the additional bwc snapshots that will never be released, such as 6.0.2, which were
being built and tested against every time we ran bwc tests.
Additionally, it creates 4 new projects that correspond to the different types of snapshots that may exist
for a given version. Its possible to now run those individual tasks to work out bwc logic whereas
previously it was impossible and the entire suite of bwc tests had to be run to work out any logic
changes in the build tools' bwc project. Please note that if the project does not make sense for the
version that is current, that an error will be thrown from that individual project if an attempt is made to
run it.
This should allow for automating the version bumps as well, since it removes all the hardcoded version
logic from the configs.
The full-cluster-restart tests are run with two nodes. This can lead to situations where the shrink tests fail because
the replicas are not allocated yet and the shrink operation needs the source shards to be available on the same node.
Lucene does not allow adding Lucene 6 files to a Lucene 7 index. This commit ensures that we carry over the Lucene version to the newly created Lucene index.
Closes#28061
The shard preference _primary, _replica and its variants were useful
for the asynchronous replication. However, with the current impl, they
are no longer useful and should be removed.
Closes#26335
The new ops based recovery, introduce as part of #10708, is based on the assumption that all operations below the global checkpoint known to the replica do not need to be synced with the primary. This is based on the guarantee that all ops below it are available on primary and they are equal. Under normal operations this guarantee holds. Sadly, it can be violated when a primary is restored from an old snapshot. At the point the restore primary can miss operations below the replica's global checkpoint, or even worse may have total different operations at the same spot. This PR introduces the notion of a history uuid to be able to capture the difference with the restored primary (in a follow up PR).
The History UUID is generated by a primary when it is first created and is synced to the replicas which are recovered via a file based recovery. The PR adds a requirement to ops based recovery to make sure that the history uuid of the source and the target are equal. Under normal operations, all shard copies will stay with that history uuid for the rest of the index lifetime and thus this is a noop. However, it gives us a place to guarantee we fall back to file base syncing in special events like a restore from snapshot (to be done as a follow up) and when someone calls the truncate translog command which can go wrong when combined with primary recovery (this is done in this PR).
We considered in the past to use the translog uuid for this function (i.e., sync it across copies) and thus avoid adding an extra identifier. This idea was rejected as it removes the ability to verify that a specific translog really belongs to a specific lucene index. We also feel that having a history uuid will serve us well in the future.
This commit adds writing build metadata to the `check` command for each
bwc project. This ensures the files will be written if doing a general
`gradle check`, which is what CI intake jobs do. In later jobs like
bwcTest, the extra bwc-release-snapshot info is needed.
Note this commit also has a little cleanup of the output for the bwc
checkout, as it was plastering a git warning, instead of the real info
we care about (the refspec and commit that were used).
At current, we do not feel there is enough of a reason to shade the low
level rest client. It caused problems with commons logging and IDE's
during the brief time it was used. We did not know exactly how many
users will need this, and decided that leaving shading out until we
gather more information is best. Users can still shade the jar
themselves. For information and feeback, see issue #26366.

The _upgrade API is no longer useful and will be removed.
Instead, see Reindex to upgrade.

Given that, I don't think we need to test the API anymore.

This commit updates the version for master to 7.0.0-alpha1. It also adds
the 6.1 version constant, and fixes many tests, as well as marking some

This commit removes all external dependencies from the rest client jar
and shades them in an 'org.elasticsearch.client' package within the jar
using shadowJar gradle plugin. All projects that depended on the
existing jar have been converted to using the 'org.elasticsearch.client'
package prefixes to interact with the rest client.

OldIndexBackwardsCompatibilityIT#testOldClusterStates tested whether global and index metadata could be read from data directory,
this can also be tested in full cluster qa test that checks cluster state via api.

Ports all of RepositoryUpgradabilityIT to qa:full-cluster-restart and ports as much of RestoreBackwardsCompatIT as possible into qa:full-cluster-restart.
This commit adds a gradle project, set inside the root build.gradle,
which controls all our bwc tests. This allows for seamless (ie no errant
CI failures) backporting of behavior.
This adds an option to `ClusterConfiguration` to preserve the
`shared` directory when starting up a new cluster and switches
the `qa:full-cluster-restart` tests to use it rather than
disable the clean shared task.

The Lucene version constants for 5.4.1 and 5.5.0 are wrong, they are
listed as 6.5.0 instead of 6.5.1. This commit fixes these issues, and
adds a test to ensure that this does not happen again.
Relates #24923
Removes the need for the `_UNRELEASED` suffix on versions by detecting if a version should be unreleased or not based on the versions around it. This should make it simpler to automate the task of adding a new version label.
These tests spin up two nodes of an older version of Elasticsearch,
create some stuff, shut down the nodes, start the current version,
and verify that the created stuff works.
You can run `gradle qa:full-cluster-restart:check` to run these
tests against the head of the previous branch of Elasticsearch
(5.x for master, 5.4 for 5.x, etc) or you can run
`gradle qa:full-cluster-restart:bwcTest` to run this test against
all "index compatible" versions, one after the other. For master
this is every released version in the 5.x.y version *and* the tip
of the 5.x branch.
I'd love to add more to these tests in the future but these
currently just cover the functionality of the `create_bwc_index.py`
script and start to cover the assertions in the
`OldIndexBackwardsCompatibilityIT` test.
