Boaz Leskes 7013cbd927 Update MockTransportService to the age of Transport.Connection (#25320)
MockTransportServices allows us to simulate network disruptions in our testing infra. Sadly it wasn't updated to the state of the art in Transport land. This PR brings it up to speed. Specifically:

1) Opening a connection is now also blocked (before only node connections were blocked)
2) Simplifies things using the latest connection based notification between TcpTransport and TransportService for when a disconnect happens.
3) By 2, it fixes a race condition where we may fail to respond to a sent request when it is sent concurrently with the closing of a connection. The old code relied on a node based bridge between tcp transport and transport service. Sadly, the following doesn't work any more:

```
   if (transport.nodeConnected(node)) {
            // this a connected node, disconnecting from it will be up the exception
            transport.disconnectFromNode(node); <-- this may now be a noop and it doesn't mean that the transport service was notified of the disconnect between the nodeConnected check and here.
   } else {
            throw new ConnectTransportException(node, reason, e);
   }
```

Simon Willnauer 86a544de3b Ensure we never read from a closed MockSecureSettings object (#25322)
If secure settings are closed after the node has been constructed
no key-store access is permitted. We should also try to be as close as possible
to the real behavior if we mock secure settings. This change also adds
the same behavior as bootstrap has to InternalTestCluster to ensure we fail
if we try to read from secure settings after the node has been constructed.

Nik Everett 3261586cac Tweak reindex cancel logic and add many debug logs (#25256)
I'm still trying to hunt down rare failures in the cancelation tests
for reindex and friends. Here is the latest:
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+5.x+multijob-unix-compatibility/os=ubuntu/876/console

It doesn't show much, other than that one of the tasks didn't kill
itself when asked to cancel.

So I'm going a bit crazy with debug logging so that the next time this
comes up I can trace exactly what happened.

Additionally, this tweaks the logic around how rethrottles were
performed around cancel. Previously we set the `requestsPerSecond`
to `0` when we cancelled the task. That was the "old way" to set them
to inifity which was the intent. This switches that from `0` to
`Float.MAX_VALUE` which is the "new way" to set the `requestsPerSecond`
to infinity. I don't know that this is much better, but it feels better.

Jay Modi 1a6491bc54 Test: do not copy secure settings when creating random directory service (#25297)
In tests, we sometimes create a random directory service and as part of that the IndexSettings get
built again. When we build them again, we need to make sure we do not set the secure settings on
the new IndexMetaData object that gets created as the node settings already have the secure
settings and the index settings and node settings will be combined. If both have secure settings,
the settings builder will throw an AlreadySetException.

Yannick Welsch 1a20760d79 Simplify IndexShard indexing and deletion methods (#25249)
Indexing or deleting documents through the IndexShard interface is quite complex and error-prone. It requires multiple calls, e.g. first prepareIndexOnPrimary, then do some checks if mapping updates have occurred, then do the actual indexing using index(...) etc. Currently each consumer of the interface (local recovery, peer recovery, replication) has additional custom checks built around it to deal with mapping updates, some of which are even inconsistent. This commit aims at reducing the complexity by exposing a simpler interface on IndexShard. There are no more prepare*** methods and the mapping complexity is also hidden, but still giving callers a possibility to implement custom logic to deal with mapping updates.

Simon Willnauer dc02b32650 Simplify connection closing and cleanups in TcpTransport (#25250)
Today we maintain a map of open connections in order to close them when
a low level channel gets closed or handles a failure. We also spawn a thread due to some
tricky concurrency issues especially with respect to netty since they listener might
be called on a transport / boss thread. Executions on those threads must not be blocking
since otherwise we will likely deadlock the event processing which adds to the
complexity of the concurrency model in this class.

This change associates the connection with the close callback that every channel invokes
once it's closed which allows us to remove the connections map. A relaxed non-blocking
concurrency model in the connection close listener allows cleaning up connected nodes without
blocking on any lock.

Nik Everett 21b1db2965 Remove assemble from build task when assemble removed
Removes the `assemble` task from the `build` task when we have
removed `assemble` from the project. We removed `assemble` from
projects that aren't published so our releases will be faster. But
That broke CI because CI builds with `gradle precommit build` and,
it turns out, that `build` includes `check` and `assemble`. With
this change CI will only run `check` for projects without an
`assemble`.

anymore since we can simply have the logic inside the base class itself. This change

Andy Bristol 48696ab544 expose simple pattern tokenizers (#25159)
Expose the experimental simplepattern and 
simplepatternsplit tokenizers in the common 
analysis plugin. They provide tokenization based 
on regular expressions, using Lucene's 
deterministic regex implementation that is usually 
faster than Java's and has protections against 
creating too-deep stacks during matching.

Both have a not-very-useful default pattern of the 
empty string because all tokenizer factories must 
be able to be instantiated at index creation time. 
They should always be configured by the user 
in practice.

the same then the response from the cluster health api will not be received as the client usually
times out first making test failures harder to debug.

Simon Willnauer 186c16ea41 Ensure pending transport handlers are invoked for all channel failures (#25150)
Today if a channel gets closed due to a disconnect we notify the response
handler that the connection is closed and the node is disconnected. Unfortunately
this is not a complete solution since it only works for published connections.
Connections that are unpublished ie. for discovery can indefinitely hang since we
never invoke their handers when we get a failure while a user is waiting for
the response. This change adds connection tracking to TcpTransport that ensures
we are notifying the corresponding connection if there is a failure on a channel.

Lee Hinman 119f8ed9f0 Correctly enable _all for older 5.x indices
When we disabled `_all` by default for indices created in 6.0, we missed adding
a layer that would handle the situation where `_all` was not enabled in 5.x and
then the cluster was updated to 6.0, this means that when the cluster was
updated the `_all` field would be disabled for 5.x indices and field values
would not be added to the `_all` field.

This adds a compatibility layer for 5.x indices where we treat the default
enabled value for the `_all` field to be `true` if unset on 5.x indices.

Jim Ferenczi 36a5cf8f35 Automatically early terminate search query based on index sorting (#24864)
This commit refactors the query phase in order to be able
to automatically detect queries that can be early terminated.
If the index sort matches the query sort, the top docs collection is early terminated
on each segment and the computing of the total number of hits that match the query is delegated to a simple TotalHitCountCollector.
This change also adds a new parameter to the search request called `track_total_hits`.
It indicates if the total number of hits that match the query should be tracked.
If false, queries sorted by the index sort will not try to compute this information and 
and will limit the collection to the first N documents per segment.
Aggregations are not impacted and will continue to see every document
even when the index sort matches the query sort and `track_total_hits` is false.

David Roberts f9503af0d5 [TEST] Move test skip/blacklist assumptions out of @Before method (#25100)
This commit moves the assumeFalse() calls that implement test skipping
and blacklisting out of the @Before method of ESClientYamlSuiteTestCase.
The problem with having them in the @Before method is that if an
assumption triggers then the @Before methods of classes that extend
ESClientYamlSuiteTestCase will not run, but their @After methods will.
This can lead to inconsistencies that cause assertions in the @After
methods and fail the test even though it was skipped/blacklisted.

Instead the assumeFalse() calls are now at the beginning of the test()
method, which runs after all @Before methods (including those in classes
that extend ESClientYamlSuiteTestCase) have completed.  The only side
effect is that overridden test() methods in classes that extend
ESClientYamlSuiteTestCase which call super.test() and also do other things
must now be designed not to consume any InternalAssumptionViolatedException
that may be thrown by the super.test() call.

Christoph Büscher 9e741cd13d Tests: Add ability to generate random new fields for xContent parsing test (#23437)
For the response parsing we want to be lenient when it comes to parsing
new xContent fields. In order to ensure this in our testing, this change
adds a utility method to XContentTestUtils that takes xContent bytes
representation as input and recursively a random field on each object
level.

Sometimes we also want to exclude a whole subtree from this treatment 
(e.g. skipping "_source"), other times an element (e.g. "fields", "highlight" 
in SearchHit) can have arbitraryly named objects. Those cases can be 
specified as exceptions.

Yannick Welsch 26ec89173b Remove TranslogRecoveryPerformer (#24858)
Splits TranslogRecoveryPerformer into three parts:
- the translog operation to engine operation converter
- the operation perfomer (that indexes the operation into the engine)
- the translog statistics (for which there is already RecoveryState.Translog)
This makes it possible for peer recovery to use the same IndexShard interface as bulk shard requests (i.e. Engine operations instead of Translog operations). It also pushes the "fail on bad mapping" logic outside of IndexShard. Future pull requests could unify the BulkShard and peer recovery path even more.

Nik Everett 190f5dce10 Test that gradle and Java version types match (#24943)
Both gradle and java code attempt to infer the type of a each
Version constant in Version.java. It is super important that

This adds a test to make sure that they agree, modulo known and

Ali Beyad e024c67561 Checks the circuit breaker before allocating bytes for a new big array (#25010)
Previously, when allocating bytes for a BigArray, the array was created
(or attempted to be created) and only then would the array be checked
for the amount of RAM used to see if the circuit breaker should trip.

This is problematic because for very large arrays, if creating or
resizing the array, it is possible to attempt to create/resize and get
an OOM error before the circuit breaker trips, because the allocation
happens before checking with the circuit breaker.

This commit ensures that the circuit breaker is checked before all big
array allocations (note, this does not effect the array allocations that
are less than 16kb which use the [Type]ArrayWrapper classes found in
BigArrays.java).  If such an allocation or resizing would cause the
circuit breaker to trip, then the breaker trips before attempting to
allocate and potentially running into an OOM error from the JVM.

ScriptContexts currently understand a FactoryType that can produce

context may take advantage of.

stateful (for example, pre loading field information for the index a

stateless and used to construct instance type instances. This change is
only a first step to cutover ScriptService to the new paradigm. It only
converts callers to the script service, and has a small shim to wrap
compilation from the script engines to support the current two fixed
instance types, SearchScript and ExecutableScript.

With #24779 in place, we can now guaranteed that a single translog generation file will never have a sequence number conflict that needs to be resolved by looking at primary terms. These conflicts can a occur when a replica contains an operation which isn't part of the history of a newly promoted primary. That primary can then assign a different operation to the same slot and replicate it to the replica.

PS. Knowing that each generation file is conflict free will simplifying repairing these conflicts when we read from the translog.

PPS. This PR also fixes some bugs in the piping of primary terms in the bulk shard action. These bugs are a result of the legacy of IndexRequest/DeleteRequest being a ReplicationRequest. We need to change that as a follow up.

InnerHitBuilderContext is now used by the parent query (nested or hasChild, ...) to build the sub context from the InnerHitBuilder definition.
BWC is also ensured so that nodes in previous versions can still send/receive inner hits to/from this version.

Nik Everett 7ef390068a Move remaining pre-configured token filters into analysis-common (#24716)
Moves the remaining preconfigured token figured into the analysis-common module. There were a couple of tests in core that depended on the pre-configured token filters so I had to touch them:

* `GetTermVectorsCheckDocFreqIT` depended on `type_as_payload` but didn't do anything important with it. I dropped the dependency. Then I moved the test to a single node test case because we're trying to cut down on the number of `ESIntegTestCase` subclasses.
* `AbstractTermVectorsTestCase` and its subclasses depended on `type_as_payload`. I dropped their usage of the token filter and added an integration test for the termvectors API that uses `type_as_payload` to the `analysis-common` module.
* `AnalysisModuleTests` expected a few pre-configured token filtes be registered by default. They aren't any more so I dropped this assertion. We assert that the `CommonAnalysisPlugin` registers these pre-built token filters in `CommonAnalysisFactoryTests`
* `SearchQueryIT` and `SuggestSearchIT` had tests that depended on the specific behavior of the token filters so I moved the tests to integration tests in `analysis-common`.

Today when an index is `read-only` the index is also blocked from

changes to a cluster indices must be deleted to free up space. This is
a likely scenario in a hosted environment when disk-space is limited to switch
indices read-only but allow deletions to free up space.

discovery with service disruptions test suite into three suites
 - master disruptions
 - discovery disruptions
 - cluster disruptions

The last one could probably be better named, it is meant to represent
performing actions in the cluster (indexing, failing a shard, etc.)
while a disruption is taking place.

This can cause connections to starve in the TransportService if the connection is
opened as a short living connection ie. without sharing the connection to a node
via registering in the transport itself. This change now moves to pruning based
on the connections cache key to ensure we notify handlers as soon as the connection
is closed for all connections not just for registered connections.

qwerty4030 e7d352b489 Compound order for histogram aggregations. (#22343)
This commit adds support for histogram and date_histogram agg compound order by refactoring and reusing terms agg order code. The major change is that the Terms.Order and Histogram.Order classes have been replaced/refactored into a new class BucketOrder. This is a breaking change for the Java Transport API. For backward compatibility with previous ES versions the (date)histogram compound order will use the first order. Also the _term and _time aggregation order keys have been deprecated; replaced by _key.

Relates to #20003: now that all these aggregations use the same order code, it should be easier to move validation to parse time (as a follow up PR).

Relates to #14771: histogram and date_histogram aggregation order will now be validated at reduce time.

Closes #23613: if a single BucketOrder that is not a tie-breaker is added with the Java Transport API, it will be converted into a CompoundOrder with a tie-breaker.

James Baiera 6a113ae499 Introduce Kerberos Test Fixture for Repository HDFS Security Tests (#24493)
This PR introduces a subproject in test/fixtures that contains a Vagrantfile used for standing up a 
KRB5 KDC (Kerberos). The PR also includes helper scripts for provisioning principals, a few 
changes to the HDFS Fixture to allow it to interface with the KDC, as well as a new suite of 
integration tests for the HDFS Repository plugin.

The HDFS Repository plugin senses if the local environment can support the HDFS Fixture 
(Windows is generally a restricted environment). If it can use the regular fixture, it then tests if 
Vagrant is installed with a compatible version to determine if the secure test fixtures should be 
enabled. If the secure tests are enabled, then we create a Kerberos KDC fixture, tasks for adding 
the required principals, and an HDFS fixture configured for security. A new integration test task is 
also configured to use the KDC and secure HDFS fixture and to run a testing suite that uses 
authentication. At the end of the secure integration test the fixtures are torn down.

Jason Tedor 8f873620ee Inline global checkpoints
Today we rely on background syncs to relay the global checkpoint under
the mandate of the primary to its replicas. This means that the global
checkpoint on a replica can lag far behind the primary. The commit moves
to inlining global checkpoints with replication requests. When a
replication operation is performed, the primary will send the latest
global checkpoint inline with the replica requests. This keeps the
replicas closer in-sync with the primary.

However, consider a replication request that is not followed by another
replication request for an indefinite period of time. When the replicas
respond to the primary with their local checkpoint, the primary will
advance its global checkpoint. During this indefinite period of time,
the replicas will not be notified of the advanced global
checkpoint. This necessitates a need for another sync. To achieve this,
we perform a global checkpoint sync when a shard falls idle.

Nik Everett bb06d8ec4f Allow plugins to build pre-configured token filters (#24223)
This changes the way we register pre-configured token filters so that
plugins can declare them and starts to move all of the pre-configured
token filters out of core. It doesn't finish the job because doing
so would make the change unreviewably large. So this PR includes
a shim that keeps the "old" way of registering pre-configured token
filters around.

The Lowercase token filter is special because there is a "special"
interaction between it and the lowercase tokenizer. I'm not sure
exactly what to do about it so for now I'm leaving it alone with
the intent of figuring out what to do with it in a followup.

This also renames these pre-configured token filters from
"pre-built" to "pre-configured" because that seemed like a more
descriptive name.

Adrien Grand a72eaa8e0f Identify documents by their `_id`. (#24460)
Now that indices have a single type by default, we can move to the next step
and identify documents using their `_id` rather than the `_uid`.

One notable change in this commit is that I made deletions implicitly create
types. This helps with the live version map in the case that documents are
deleted before the first type is introduced. Otherwise there would be no way
to differenciate `DELETE index/foo/1` followed by `PUT index/foo/1` from
`DELETE index/bar/1` followed by `PUT index/foo/1`, even though those are
different if versioning is involved.

Yannick Welsch 35f78d098a Separate publishing from applying cluster states (#24236)
Separates cluster state publishing from applying cluster states:

- ClusterService is split into two classes MasterService and ClusterApplierService. MasterService has the responsibility to calculate cluster state updates for actions that want to change the cluster state (create index, update shard routing table, etc.). ClusterApplierService has the responsibility to apply cluster states that have been successfully published and invokes the cluster state appliers and listeners.
- ClusterApplierService keeps track of the last applied state, but MasterService is stateless and uses the last cluster state that is provided by the discovery module to calculate the next prospective state. The ClusterService class is still kept around, which now just delegates actions to ClusterApplierService and MasterService.
- The discovery implementation is now responsible for managing the last cluster state that is used by the consensus layer and the master service. It also exposes the initial cluster state which is used by the ClusterApplierService. The discovery implementation is also responsible for adding the right cluster-level blocks to the initial state.
- NoneDiscovery has been renamed to TribeDiscovery as it is exclusively used by TribeService. It adds the tribe blocks to the initial state.
- ZenDiscovery is synchronized on state changes to the last cluster state that is used by the consensus layer and the master service, and does not submit cluster state update tasks anymore to make changes to the disco state (except when becoming master).

Control flow for cluster state updates is now as follows:

- State updates are sent to MasterService
- MasterService gets the latest committed cluster state from the discovery implementation and calculates the next cluster state to publish
- MasterService submits the new prospective cluster state to the discovery implementation for publishing
- Discovery implementation publishes cluster states to all nodes and, once the state is committed, asks the ClusterApplierService to apply the newly committed state.
- ClusterApplierService applies state to local node.

We want to upgrade to Lucene 7 ahead of time in order to be able to check whether it causes any trouble to Elasticsearch before Lucene 7.0 gets released. From a user perspective, the main benefit of this upgrade is the enhanced support for sparse fields, whose resource consumption is now function of the number of docs that have a value rather than the total number of docs in the index.

Some notes about the change:
 - it includes the deprecation of the `disable_coord` parameter of the `bool` and `common_terms` queries: Lucene has removed support for coord factors
 - it includes the deprecation of the `index.similarity.base` expert setting, since it was only useful to configure coords and query norms, which have both been removed
 - two tests have been marked with `@AwaitsFix` because of #23966, which we intend to address after the merge

Jason Tedor 8033c576b7 Detect remnants of path.data/default.path.data bug
In Elasticsearch 5.3.0 a bug was introduced in the merging of default
settings when the target setting existed as an array. When this bug
concerns path.data and default.path.data, we ended up in a situation
where the paths specified in both settings would be used to write index
data. Since our packaging sets default.path.data, users that configure
multiple data paths via an array and use the packaging are subject to
having shards land in paths in default.path.data when that is very
likely not what they intended.

This commit is an attempt to rectify this situation. If path.data and
default.path.data are configured, we check for the presence of indices
there. If we find any, we log messages explaining the situation and fail
the node.

Ryan Ernst 65f7a76630 Settings: Add secure file setting to keystore (#24001)
Some systems like GCE rely on a plaintext file containing credentials.
Rather than extract the information out of that credentials file and
store each peace individually in the keystore, it is cleaner to just
store the entire file.

This commit adds support to the keystore wrapper for secure file
settings. These are settings that contain an entire file that would
normally be stored on the local filesystem. Retrieving the file returns
an input stream to the file contents. This also adds a `add-file`
command to the keystore cli.

In order to support both strings and files as values for settings, the
metadata format of the keystore has also been updated (with backcompat)
to keep a map of setting name to type.

Yannick Welsch a3cceb8a00 [TEST] Fix testMultipleNodesShutdownNonMasterNodes to wait for the right nodes to rejoin the cluster
This test was sporadically failing for the following reason:
- 4 nodes (nodes 0, 1, 2, and 3) running with `minimum_master_nodes` set to 3
- we stop 2 nodes (node 0 and 3)
- wait for cluster block to be in place on all nodes
- start 2 nodes (node 4 and node 5) and do a `prepareHealth().setWaitForNodes("4")`
- then do a search request

The search request runs into the `ClusterBlockException` as the `prepareHealth().setWaitForNodes("4")` check succeeds on a cluster state that has
nodes 1, 2, 3, and 4, i.e., only one of the two new nodes has joined the cluster and only one of the two dead nodes was removed by the master
(removing the dead nodes only happens after there are again `minimum_master_nodes` nodes in the cluster).

Jason Tedor 48357e43d3 Honor update request timeout
When executing an update request, the request timeout is not transferred
to the index/delete request executed on behalf of the update
request. This leads to update requests not timing out when they should
(e.g., if not all shards are available when the request specifies
wait_for_shards=all with a small timeout). This commit causes the
index/delete requests to honor the update request timeout.

Jason Tedor 7b17689458 Search took time should use a relative clock
Search took time uses an absolute clock to measure elapsed time, and
then tries to deal with the complexities of using an absolute clock for
this purpose. Instead, we should use a high-precision monotonic relative
clock that is designed exactly for measuring elapsed time. This commit
modifies the search infrastructure to use a relative clock for measuring
took time, but still provides an absolute clock for the components of
search that require a real clock (e.g., index name expression
resolution, etc.).

Jason Tedor 577e6a5e14 Correct warning header to be compliant
The warning header used by Elasticsearch for delivering deprecation
warnings has a specific format (RFC 7234, section 5.5). The format
specifies that the warning header should be of the form

    warn-code warn-agent warn-text [warn-date]

Here, the warn-code is a three-digit code which communicates various
meanings. The warn-agent is a string used to identify the source of the
warning (either a host:port combination, or some other identifier). The
warn-text is quoted string which conveys the semantic meaning of the
warning. The warn-date is an optional quoted date that can be in a few
different formats.

This commit corrects the warning header within Elasticsearch to follow
this specification. We use the warn-code 299 which means a
"miscellaneous persistent warning." For the warn-agent, we use the
version of Elasticsearch that produced the warning. The warn-text is
unchanged from what we deliver today, but is wrapped in quotes as
specified (this is important as a problem that exists today is that
multiple warnings can not be split by comma to obtain the individual
warnings as the warnings might themselves contain commas). For the
warn-date, we use the RFC 1123 format.

Adrien Grand 8d6a41f671 Nested queries should avoid adding unnecessary filters when possible. (#23079)
When nested objects are present in the mappings, many queries get deoptimized
due to the need to exclude documents that are not in the right space. For
instance, a filter is applied to all queries that prevents them from matching
non-root documents (`+*:* -_type:__*`). Moreover, a filter is applied to all
child queries of `nested` queries in order to make sure that the child query
only matches child documents (`_type:__nested_path`), which is required by
`ToParentBlockJoinQuery` (the Lucene query behing Elasticsearch's `nested`
queries).

These additional filters slow down `nested` queries. In 1.7-, the cost was
somehow amortized by the fact that we cached filters very aggressively. However,
this has proven to be a significant source of slow downs since 2.0 for users
of `nested` mappings and queries, see #20797.

This change makes the filtering a bit smarter. For instance if the query is a
`match_all` query, then we need to exclude nested docs. However, if the query
is `foo: bar` then it may only match root documents since `foo` is a top-level
field, so no additional filtering is required.

Another improvement is to use a `FILTER` clause on all types rather than a
`MUST_NOT` clause on all nested paths when possible since `FILTER` clauses
are more efficient.

Here are some examples of queries and how they get rewritten:

```
"match_all": {}
```

This query gets rewritten to `ConstantScore(+*:* -_type:__*)` on master and
`ConstantScore(_type:AutomatonQuery {\norg.apache.lucene.util.automaton.Automaton@4371da44})`
with this change. The automaton is the complement of `_type:__*` so it matches
the same documents, but is faster since it is now a positive clause. Simplistic
performance testing on a 10M index where each root document has 5 nested
documents on average gave a latency of 420ms on master and 90ms with this change
applied.

```
"term": {
  "foo": {
    "value": "0"
  }
}
```

This query is rewritten to `+foo:0 #(ConstantScore(+*:* -_type:__*))^0.0` on
master and `foo:0` with this change: we do not need to filter nested docs out
since the query cannot match nested docs. While doing performance testing in
the same conditions as above, response times went from 250ms to 50ms.

```
"nested": {
  "path": "nested",
  "query": {
    "term": {
      "nested.foo": {
        "value": "0"
      }
    }
  }
}
```

This query is rewritten to
`+ToParentBlockJoinQuery (+nested.foo:0 #_type:__nested) #(ConstantScore(+*:* -_type:__*))^0.0`
on master and `ToParentBlockJoinQuery (nested.foo:0)` with this change. The
top-level filter (`-_type:__*`) could be removed since `nested` queries only
match documents of the parent space, as well as the child filter
(`#_type:__nested`) since the child query may only match nested docs since the
`nested` object has both `include_in_parent` and `include_in_root` set to
`false`. While doing performance testing in the same conditions as above,
response times went from 850ms to 270ms.

Jason Tedor 5343b87502 Handle bad HTTP requests
When Netty decodes a bad HTTP request, it marks the decoder result on
the HTTP request as a failure, and reroutes the request to GET
/bad-request. This either leads to puzzling responses when a bad request
is sent to Elasticsearch (if an index named "bad-request" does not exist
then it produces an index not found exception and otherwise responds
with the index settings for the index named "bad-request"). This commit
addresses this by inspecting the decoder result on the HTTP request and
dispatching the request to a bad request handler preserving the initial
cause of the bad request and providing an error message to the client.

When a node receives a new cluster state from the master, it opens up connections to any new node in the cluster state. That has always been done serially on the cluster state thread but it has been a long standing TODO to do this concurrently, which is done by this PR.

This is spin off of #22828, where an extra handshake is done whenever connecting to a node, which may slow down connecting. Also, the handshake is done in a blocking fashion which triggers assertions w.r.t blocking requests on the cluster state thread. Instead of adding an exception, I opted to implement concurrent connections which both side steps the assertion and compensates for the extra handshake.

Jay Modi 7520a107be Optionally require a valid content type for all rest requests with content (#22691)
This change adds a strict mode for xcontent parsing on the rest layer. The strict mode will be off by default for 5.x and in a separate commit will be enabled by default for 6.0. The strict mode, which can be enabled by setting `http.content_type.required: true` in 5.x, will require that all incoming rest requests have a valid and supported content type header before the request is dispatched. In the non-strict mode, the Content-Type header will be inspected and if it is not present or not valid, we will continue with auto detection of content like we have done previously.

The content type header is parsed to the matching XContentType value with the only exception being for plain text requests. This value is then passed on with the content bytes so that we can reduce the number of places where we need to auto-detect the content type.

As part of this, many transport requests and builders were updated to provide methods that
accepted the XContentType along with the bytes and the methods that would rely on auto-detection have been deprecated.

In the non-strict mode, deprecation warnings are issued whenever a request with body doesn't provide the Content-Type header.

 This commit adds a test that creates situation where rollback is needed (primary failover with ops in flight) and fixes another issue that was surfaced by it - if a primary can't serve a seq# based recovery request and does a file copy, it still used the incoming `startSeqNo` as a filter.

Jason Tedor 930282e161 Introduce sequence-number-based recovery
This commit introduces sequence-number-based recovery. When a replica
has fallen out of sync, rather than performing a file-based recovery we
first attempt to replay operations since the last local checkpoint on
the replica. To do this, at the start of recovery the replica tells the
primary what its local checkpoint is. The primary will then wait for all
operations between that local checkpoint and the current maximum
sequence number to complete; this is to ensure that there are no gaps in
the operations that will be replayed from the primary to the
replica. This is a best-effort attempt as we currently have no
guarantees on the primary that these operations will be available; if we
are not able to replay all operations in the desired range, we just
fallback to file-based recovery. Later work will strengthen the
guarantees.

The distributed aspect is resolve using the two passes that the regular search uses. The first pass "collapse" the top hits, then the coordinating node merge/collapse the top hits from each shard.

```
GET _search
{
   "collapse": {
      "field": "category",
   }
}
```

This change also adds an ExpandCollapseSearchResponseListener that intercepts the search response and expands collapsed hits using the CollapseBuilder#innerHit} options.
The retrieval of each inner_hits is done by sending a query to all shards filtered by the collapse key.

```
GET _search
{
   "collapse": {
      "field": "category",
      "inner_hits": {
	"size": 2
      }
   }
}
```

Simon Willnauer 27b5c2ad54 Pass `forceExecution` flag to transport interceptor (#22739)
To effectively allow a plugin to intercept a transport handler it needs
to know if the handler must be executed even if there is a rejection on the
thread pool in the case the wrapper forks a thread to execute the actual handler.

Simon Willnauer 824beea89d Fix handling of document failure expcetion in InternalEngine (#22718)
Today we try to be smart and make a generic decision if an exception should
be treated as a document failure but in some cases concurrency in the index writer
make this decision very difficult since we don't have a consistent state in the case
another thread is currently failing the IndexWriter/InternalEngine due to a tragic event.

This change simplifies the exception handling and makes specific decisions about document failures
rather than using a generic heuristic. This prevent exceptions to be treated as document failures
that should have failed the engine but backed out of failing since since some other thread has
already taken over the failure procedure but didn't finish yet.

Simon Willnauer 24e2847af2 Streamline foreign stored context restore and allow to perserve response headers (#22677)
Today we do not preserve response headers if they are present on a transport protocol
response. While preserving these headers is not always desired, in the most cases we
should pass on these headers to have consistent results for depreciation headers etc.
yet, this hasn't been much of a problem since most of the deprecations are detected early
ie. on the coordinating node such that this bug wasn't uncovered until #22647

This commit allow to optionally preserve headers when a context is restored and also streamlines
the context restore since it leaked frequently into the callers thread context when the callers
context wasn't restored again.

Ali Beyad e2977889b8 Allow comma delimited array settings to have a space after each entry (#22591)
Previously, certain settings that could take multiple comma delimited
values would pick up incorrect values for all entries but the first if
each comma separated value was followed by a whitespace character.  For
example, the multi-value "A,B,C" would be correctly parsed as
["A", "B", "C"] but the multi-value "A, B, C" would be incorrectly parsed
as ["A", " B", " C"].

This commit allows a comma separated list to have whitespace characters
after each entry.  The specific settings that were affected by this are:

  cluster.routing.allocation.awareness.attributes
  index.routing.allocation.require.*
  index.routing.allocation.include.*
  index.routing.allocation.exclude.*
  cluster.routing.allocation.require.*
  cluster.routing.allocation.include.*
  cluster.routing.allocation.exclude.*
  http.cors.allow-methods
  http.cors.allow-headers

For the allocation filtering related settings, this commit also provides
validation of each specified entry if the filtering is done by _ip,
_host_ip, or _publish_ip, to ensure that each entry is a valid IP
address.

Moving this to the low level REST client will allow the high level REST client to make use of it too, for instance so that it doesn't have to intercept ResponseExceptions when the get api returns a 404.

Simon Willnauer 4c1ee018f6 Remove setLocalNode from ClusterService and TransportService (#22608)
ClusterService and TransportService expect the local discovery node to be set
before they are started but this requires manual interaction and is error prone since
to work absolutely correct they should share the same instance (same ephemeral ID).

TransportService also has 2 modes of operation, mainly realted to transport client vs. internal
to a node. This change removes the mode where we don't maintain a local node and uses a dummy local
node in the transport client since we don't bind to any port in such a case.

Local discovery node instances are now managed by the node itself and only suppliers and factories that allow
creation only once are passed to TransportService and ClusterService.

Luca Cavanna 7674de9e1f Move human flag under always accepted query_string params (#22562)
There are some parameters that are accepted by each and every api we expose. Those (pretty, source, error_trace and filter_path)  are not explicitly listed in the spec of every api, rather whitelisted in clients test runners so that they are always accepted. The `human` flag has been treated up until now as a parameter that's accepted by only some stats and info api, but that doesn't reflect reality as es core treats it exactly like `pretty` (relevant especially now that we validate params and throw exception when we find one that is not supported). Furthermore, the human flag has effect on every api that outputs a date, time, percentage or byte size field. For instance the tasks api outputs a date field although they don't have the human flag explicitly listed in their spec. There are other similar cases. This commit removes the human flag from the rest spec and makes it an always accepted query_string param.

Yannick Welsch 9fc1a735cc Keep NodeConnectionsService in sync with current nodes in the cluster state (#22509)
The NodeConnectionsService currently determines which nodes to connect to / disconnect from by inspecting cluster state changes and connecting to added nodes / disconnecting from removed nodes. When a master steps down (for example due to another master-eligible node shutting down which brings the number of master-eligible nodes below minimum_master_master), and the connection to other existing nodes was dropped while pinging, however, the connection to these nodes is not re-established while publishing the first cluster state that establishes the node as master.
This commit changes the NodeConnectionsService connect / disconnect logic to always rely on the state that is to be / was published, looking not only at the added / removed nodes, but validating that exactly all nodes that are currently registered in NodeConnectionsService are connected (corresponds to a NOOP if the node is already connected).

Nik Everett 12923ef896 Close and flush refresh listeners on shard close
Right now closing a shard looks like it strands refresh listeners,
causing tests like
`delete/50_refresh/refresh=wait_for waits until changes are visible in search`
to fail. Here is a build that fails:
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+multi_cluster_search+multijob-darwin-compatibility/4/console

This attempts to fix the problem by implements `Closeable` on
`RefreshListeners` and rejecting listeners when closed. More importantly
the act of closing the instance flushes all pending listeners
so we shouldn't have any stranded listeners on close.

Because it was needed for testing, this also adds the number of
pending listeners to the `CommonStats` object and all API to which
that flows: `_cat/nodes`, `_cat/indices`, `_cat/shards`, and
`_nodes/stats`.

Ryan Ernst fb690ef748 Settings: Add infrastructure for elasticsearch keystore
This change is the first towards providing the ability to store
sensitive settings in elasticsearch. It adds the
`elasticsearch-keystore` tool, which allows managing a java keystore.
The keystore is loaded upon node startup in Elasticsearch, and used by
the Setting infrastructure when a setting is configured as secure.

There are a lot of caveats to this PR. The most important is it only
provides the tool and setting infrastructure for secure strings. It does
not yet provide for keystore passwords, keypairs, certificates, or even
convert any existing string settings to secure string settings. Those
will all come in follow up PRs. But this PR was already too big, so this
at least gets a basic version of the infrastructure in.

The two main things to look at.  The first is the `SecureSetting` class,
which extends `Setting`, but removes the assumption for the raw value of the
setting to be a string. SecureSetting provides, for now, a single
helper, `stringSetting()` to create a SecureSetting which will return a
SecureString (which is like String, but is closeable, so that the
underlying character array can be cleared). The second is the
`KeyStoreWrapper` class, which wraps the java `KeyStore` to provide a
simpler api (we do not need the entire keystore api) and also extend
the serialized format to add metadata needed for loading the keystore
with no assumptions about keystore type (so that we can change this in
the future) as well as whether the keystore has a password (so that we
can know whether prompting is necessary when we add support for keystore
passwords).

Jason Tedor 7946396fe6 Introduce translog no-op
As the translog evolves towards a full operations log as part of the
sequence numbers push, there is a need for the translog to be able to
represent operations for which a sequence number was assigned, but the
operation did not mutate the index. Examples of how this can arise are
operations that fail after the sequence number is assigned, and gaps in
this history that arise when an operation is assigned a sequence number
but the operation never completed (e.g., a node crash). It is important
that these operations appear in the history so that they can be
replicated and replayed during recovery as otherwise the history will be
incomplete and local checkpoints will not be able to advance. This
commit introduces a no-op to the translog to set the stage for these
efforts.

Boaz Leskes 0e9186e137 Simplify Unicast Zen Ping (#22277)
The `UnicastZenPing` shows it's age and is the result of many small changes. The current state of affairs is confusing and is hard to reason about. This PR cleans it up (while following the same original intentions). Highlights of the changes are:

1) Clear 3 round flow - no interleaving of scheduling.
2) The previous implementation did a best effort attempt to wait for ongoing pings to be sent and completed. The pings were guaranteed to complete because each used the total ping duration as a timeout. This did make it hard to reason about the total ping duration and the flow of the code. All of this is removed now and ping should just complete within the given duration or not be counted (note that it was very handy for testing, but I move the needed sync logic to the test).
3) Because of (2) the pinging scheduling changed a bit, to give a chance for the last round to complete. We now ping at the beginning, 1/3 and 2/3 of the duration.
4) To offset for (3) a bit, incoming ping requests are now added to on going ping collections.
5) UnicastZenPing never establishes full blown connections (but does reuse them if there). Relates to #22120
6) Discovery host providers are only used once per pinging round. Closes #21739
7) Usage of the ability to open a connection without connecting to a node ( #22194 ) and shorter connection timeouts helps with connections piling up. Closes #19370
8) Beefed up testing and sped them up.
9) removed light profile from production code

Luca Cavanna ae01a51b44 [TEST] make ESSingleNodeTestCase tests repeatable (#22283)
If we conditionally do random things, e.g. initialize a node only after the first test, we have to make sure that we unconditionally create a new seed calling random.nextLong(), then initialize the node under a private randomness context. This makes sure that any random usage through Randomness.get() will retrieve the proper random instance through RandomizedContext.current().getRandom(). When running under private randomness, the context will return the Random instance that was created with the provided seed (forked from the main random instance) rather than the main Random that's exposed to tests as well. Otherwise tests become non repeatable because that initialization part happens only before the first executed test.

Nik Everett a04dcfb95b Introduce XContentParser#namedObject (#22003)
Introduces `XContentParser#namedObject which works a little like
`StreamInput#readNamedWriteable`: on startup components register
parsers under names and a superclass. At runtime we look up the
parser and call it to parse the object.

Right now the parsers take a context object they use to help with
the parsing but I hope to be able to eliminate the need for this
context as most what it is used for at this point is to move
around parser registries which should be replaced by this method
eventually. I make no effort to do so in this PR because it is
big enough already. This is meant to the a start down a road that
allows us to remove classes like `QueryParseContext`,
`AggregatorParsers`, `IndicesQueriesRegistry`, and
`ParseFieldRegistry`.

The goal here is to reduce the amount of plumbing required to
allow parsing pluggable things. With this you don't have to pass
registries all over the place. Instead you must pass a super
registry to fewer places and use it to wrap the reader. This is
the same tradeoff that we use for NamedWriteable and it allows
much, much simpler binary serialization. We think we want that
same thing for xcontent serialization.

The only parsing actually converted to this method is parsing
`ScoreFunctions` inside of `FunctionScoreQuery`. I chose this
because it is relatively self contained.

This change renames and changes the behavior of SettingCommand to have
its primary method take in a fully initialized Environment for
elasticsearch instead of just a map of settings. All of the subclasses

javanna 5dae10db11 [TEST] add warnings check to ESTestCase
We are currenlty checking that no deprecation warnings are emitted in our query tests. That can be moved to ESTestCase (disabled in ESIntegTestCase) as it allows us to easily catch where our tests use deprecated features and assert on the expected warnings.

javanna 6a27628f12 Remove support for strict parsing mode
We return deprecation warnings as response headers, besides logging them. Strict parsing mode stayed around, but was only used in query tests, though we also introduced checks for deprecation warnings there that don't need strict parsing anymore (see #20993).

 We can then safely remove support for strict parsing mode. The final goal is to remove the ParseFieldMatcher class, but there are many many users of it. This commit prepares the field for the removal, by deprecating ParseFieldMatcher and making it effectively not needed. Strict parsing is removed from ParseFieldMatcher, and strict parsing is replaced in tests where needed with deprecation warnings checks.

 Note that the setting to enable strict parsing was never ported to the new settings infra hance it cannot be set in production. It is really only used in our own tests.

Luca Cavanna 3421e54a42 Add fromXContent method to GetResponse (#22082)
Moved field values `toXContent` logic to `GetField` (from `GetResult`), which outputs its own fields, and can also parse them now. Also added `fromXContent` to `GetResult` and `GetResponse`.

 The start object and end object for `GetResponse` output have been moved to `GetResult#toXContent`, from the corresponding rest action. This makes it possible to have `toXContent` and `fromXContent` completely symmetric, as parsing requires looping till an end object is found which is weird when the corresponding `toXContent` doesn't print that out.

This also introduces the foundation for testing retrieval of _source and stored field values.

Boaz Leskes b857b316b6 Add BWC layer to seq no infra and enable BWC tests (#22185)
Sequence BWC logic consists of two elements:

1) Wire level BWC using stream versions.
2) A changed to the global checkpoint maintenance semantics.

For the sequence number infra to work with a mixed version clusters, we have to consider situation where the primary is on an old node and replicas are on new ones (i.e., the replicas will receive operations without seq#) and also the reverse (i.e., the primary sends operations to a replica but the replica can't process the seq# and respond with local checkpoint). An new primary with an old replica is a rare because we do not allow a replica to recover from a new primary. However, it can occur if the old primary failed and a new replica was promoted or during primary relocation where the source primary is treated as a replica until the master starts the target.

1) Old Primary & New Replica - this case is easy as is taken care of by the wire level BWC. All incoming requests will have their seq# set to `UNASSIGNED_SEQ_NO`, which doesn't confuse the local checkpoint logic (keeping it at `NO_OPS_PERFORMED`) 
2) New Primary & Old replica - this one is trickier as the global checkpoint service currently takes all in sync replicas into consideration for the global checkpoint calculation. In order to deal with old replicas, we change the semantics to say all *new node* in sync replicas. That means the replicas on old nodes don't count for the global checkpointing. In this state the seq# infra is not fully operational (you can't search on it, because copies may miss it) but it is maintained on shards that can support it. The old replicas will have to go through a file based recovery at some point and will get the seq# information at that point. There is still an edge case where a new primary fails and an old replica takes over. I'lll discuss this one with @ywelsch as I prefer to avoid it completely.

This PR also re-enables the BWC tests which were disabled. As such it had to fix any BWC issue that had crept in. Most notably an issue with the removal of the `timestamp` field in #21670.

The commit also includes a fix for the default value of the seq number field in replicated write requests (it was 0 but should be -2), that surface some other minor bugs which are fixed as well.

Last - I added some debugging tools like more sane node names and forcing replication request to implement a `toString`

Jason Tedor 58d73bae74 Tighten sequence numbers recovery
This commit touches addresses issues related to recovery and sequence numbers:
 - A sequence number can be assigned and a Lucene commit created with a
   maximum sequence number at least as large as that sequence number,
   yet the operation corresponding to that sequence number can be
   missing from both the Lucene commit and the translog. This means that
   upon recovery the local checkpoint will be stuck at or below this
   missing sequence number. To address this, we force the local
   checkpoint to the maximum sequence number in the Lucene commit when
   opening the engine. Note that there can still be gaps in the history
   in the translog but we do not address those here.
 - The global checkpoint is transferred to the target shard at the end
   of peer recovery.
 - Additionally, we reenable the relocation integration tests.

Lastly, this work uncovered some bugs in the assignment of sequence
numbers on replica operations:
 - setting the sequence number on replica write requests was missing,
   very likely introduced as a result of resolving merge conflicts
 - handling operations that arrive out of order on a replica and have a
   version conflict with a previous operation were never marked as
   processed

Simon Willnauer 1f3eb068d5 Add infrastructure to manage network connections outside of Transport/TransportService (#22194)
Some expert users like UnicastZenPing today establishes real connections to nodes during it's ping
phase that can be used by other parts of the system. Yet, this is potentially dangerous
and undesirable unless the nodes have been fully verified and should be connected to in the
case of a cluster state update or if we join a newly elected master. For use-cases like this, this change adds the infrastructure to manually handle connections that are not publicly available on the node ie. should not be managed by `Transport`/`TransportSerivce`

Boaz Leskes b6cbcc49ba ClusterService should expose "applied" cluster states (i.e., remove ClusterStateStatus) (#21817)
`ClusterService` is responsible of updating the cluster state on every node (as a response to an API call on the master and when non-masters receive a new state from the master). When a new cluster state is processed, it is made visible via the `ClusterService#state` method and is sent to series of listeners. Those listeners come in two flavours - one is to change the state of the node in response to the new cluster state (call these cluster state appliers), the other is to start a secondary process. Examples for the later include an indexing operation waiting for a shard to be started or a master node action waiting for a master to be elected. 

The fact that we expose the state before applying it means that samplers of the cluster state had to worry about two things - working based on a stale CS and working based on a future, i.e., "being applied" CS. The `ClusterStateStatus` was used to allow distinguishing between the two. Working with a stale cluster state is not avoidable. How this PR changes things to make sure consumers don't need to worry about future CS, removing the need for the status and simplifying the waiting logic.

This change does come with a price as "cluster state appliers" can't sample the cluster state from `ClusterService` whenever they want as the cluster state isn't exposed yet. However, recent clean ups made this is situation easier and this PR takes the last steps to remove such sampling. This also helps clarify the "information flow" and helps component separation (and thus potential unit testing). It also adds an assertion that will trigger if the cluster state is sampled by such listeners. 

Note that there are still many "appliers" that could be made a simpler, unrestricted "listener" but this can be done in smaller bits in the future. The commit also makes it clear what the `appliers` and what the `listeners` are by using dedicated interfaces.

Also, since I had to change the listener types I went ahead and changed the data structure for temporary/timeout listeners (used for the observer) so addition and removal won't be an O(n) operation.

Simon Willnauer 7a9b667e98 Introduce a low level protocol handshake (#22094)
Today we rely on the version that the API user passes in together with the DiscoveryNode. This commit introduces a low level handshake where nodes exchange their version to be used with the transport protocol that is executed every time a connection to a node is established. This, on the one hand allows to change the wire protocol based on the version we are talking to even without a full cluster restart. Today we would need to carry on a BWC layer across major versions but with a handshake we can rely on the fact that the latest version of the previous minor executes a handshake and uses the latest protocol version across all communication with the N+1 version nodes.

This change is yet fully backwards compatible, a followup PR will remove the BWC in 6.0 once this has been back-ported to the 5.x branch

This commit enhances the allocator decision result objects (namely,

which will form the explain API responses.
- Moves the calculation of the final explanation to the response
object itself, removing it from the responsibility of the allocators.
- Adds shard store information to the NodeAllocationResult, so that
store information is available for each node, when explaining a
shard allocation by the PrimaryShardAllocator or the ReplicaShardAllocator.
- Removes RebalanceDecision in favor of using MoveDecision for both
moving and rebalancing shards.
- Removes NodeRebalanceResult in favor of using NodeAllocationResult.
- Changes the notion of weight ranking to be relative to the current node,
instead of an absolute weight that doesn't convey any added value to the
API user and can be confusing.
- Introduces a new enum AllocationDecision to convey the decision type,
which enables conveying unassigned, moving, and rebalancing scenarios
with more detail as opposed to just Decision.Type and AllocationStatus.

Since the removal of local discovery of #https://github.com/elastic/elasticsearch/pull/20960 we rely on minimum master nodes to be set in our test cluster. The settings is automatically managed by the cluster (by default) but current management doesn't work with concurrent single node async starting. On the other hand, with `MockZenPing` and the `discovery.initial_state_timeout` set to `0s` node starting and joining is very fast making async starting an unneeded complexity. Test that still need async starting could, in theory, still do so themselves via background threads.

Note that this change also removes the usage of `INITIAL_STATE_TIMEOUT_SETTINGS` as the starting of nodes is done concurrently (but building them is sequential)

Nicholas Knize af1ab68b64 Add RangeFieldMapper for numeric and date range types
Lucene 6.2 added index and query support for numeric ranges. This commit adds a new RangeFieldMapper for indexing numeric (int, long, float, double) and date ranges and creating appropriate range and term queries. The design is similar to NumericFieldMapper in that it uses a RangeType enumerator for implementing the logic specific to each type. The following range types are supported by this field mapper: int_range, float_range, long_range, double_range, date_range.

Lucene does not provide a DocValue field specific to RangeField types so the RangeFieldMapper implements a CustomRangeDocValuesField for handling doc value support.

When executing a Range query over a Range field, the RangeQueryBuilder has been enhanced to accept a new relation parameter for defining the type of query as one of: WITHIN, CONTAINS, INTERSECTS.

dedicated bulks and recovery connections.

Luca Cavanna 360b74eda8 [TEST] Don't reinitialize YamlTestClient and RestClient before each single test (#21807)
In the past we ran yaml tests against an internal cluster, which would get restarted after each test failure, hence the client objects needed to eventually be refreshed before each test. That is why we had the initClient method to re-initialize the YamlTestClient in the execution context. We ended up though re-initializing the client unconditionally, which is not needed.

Also, ESRestTestCase recreates the RestClient against the external cluster before each test, which is not needed given that nothing changes in the external cluster.

This commit removes the initClient method from the yaml tests execution context. The YamlTestClient can be eagerly created before the first yaml test runs and then re-used in subsequent tests. Also api calls to check for nodes versions etc. are moved out of YamlTestClient to ESClientYamlSuiteTestCase. Also the RestClient is now initialized in ESRestTestCase before the first test runs, and kept around afterwards as a static member.

Basically each subclass of EsRestTestCase will have its own RestClient instance, but the client will be shared across the different tests within the same class. The yaml test suite is just a special suite, composed of 600+ tests that are loaded from files, which will share the same client instance.

This change should speed tests up as well, as we don't recreate the RestClient before each single test, and we don't call _cat/nodes either before each single test.

Yannick Welsch 7e198f0e41 Detect nodes being blocked by GC-disrupted node (#21797)
The disruption type LongGCDisruption simulates GCs on a node by suspending all the threads of that node. If the suspended threads are in a code section with shared JVM locks, however, it can prevent the other nodes from doing their thing. The class LongGCDisruption has a list of class names for which we know that this can occur. Whenever a test using the GC disruption type fails in mysterious ways, it becomes a long guessing game to find the offending class. This commit adds code to LongGCDisruption to automatically detect these situations, fail the test early and report the offending class and all relevant context.

if a hostname  gets resolved to an IP but that host is disconnected clients want
to reconnect by resolving the hostname again which is a common situation in cloud

Jason Tedor 9dc65037bc Lazy resolve unicast hosts
Today we eagerly resolve unicast hosts. This means that if DNS changes,
we will never find the host at the new address. Moreover, a single host
failng to resolve causes startup to abort. This commit introduces lazy
resolution of unicast hosts. If a DNS entry changes, there is an
opportunity for the host to be discovered. Note that under the Java
security manager, there is a default positive cache of infinity for
resolved hosts; this means that if a user does want to operate in an
environment where DNS can change, they must adjust
networkaddress.cache.ttl in their security policy. And if a host fails
to resolve, we warn log the hostname but continue pinging other
configured hosts.

When doing DNS resolutions for unicast hostnames, we wait until the DNS
lookups timeout. This appears to be forty-five seconds on modern JVMs,
and it is not configurable. If we do these serially, the cluster can be
blocked during ping for a lengthy period of time. This commit introduces
doing the DNS lookups in parallel, and adds a user-configurable timeout
for these lookups.

Areek Zillur 0ccf8a742d Add support for merging custom meta data in tribe node (#21552)
* Add support for merging custom meta data in tribe node

Currently, when any underlying cluster has custom metadata
(via plugin), tribe node does not store custom meta data in its
cluster state. This is because the tribe node has no idea how to
select the appropriate custom metadata from one or many custom
metadata (corresponding to the number of underlying clusters).

This change adds an interface that custom metadata implementations
can extend to add support for merging mulitple custom metadata of
the same type for storing in the tribe state.

Adrien Grand 00de8e07fc Do not cache term queries. (#21566)
There have been reports that the query cache did not manage to speed up search
requests when the query includes a large number of different sub queries since
a single request may manage to exhaust the whole history (256 queries) while
the query cache only starts caching queries once they appear multiple times in
the history (#16031). On the other hand, increasing the size of the query cache
is a bit controversial (#20116) so this pull request proposes a different
approach that consists of never caching term queries, and not adding them to the
history of queries either. The reasoning is that these queries should be fast
anyway, regardless of caching, so taking them out of the equation should not
cause any slow down. On the other hand, the fact that they are not added to the
cache history anymore means that other queries have greater chances of being
cached.

Boaz Leskes d6c2b4f7c5 Adapt InternalTestCluster to auto adjust `minimum_master_nodes` (#21458)
#20960 removed `LocalDiscovery` and we now use `ZenDiscovery` in all our tests. To keep cluster forming fast, we are using a `MockZenPing` implementation which uses static maps to return instant results making master election fast. Currently, we don't set `minimum_master_nodes` causing the occasional split brain when starting multiple nodes concurrently and their pinging is so fast that it misses the fact that one of the node has elected it self master. To solve this, `InternalTestCluster` is modified to behave like a true cluster and manage and set `minimum_master_nodes` correctly with every change to the number of nodes.

Tests that want to manage the settings themselves can opt out using a new `autoMinMasterNodes` parameter to the `ClusterScope` annotation. 

Having `min_master_nodes` set means the started node may need to wait for other nodes to be started as well. To combat this, we set `discovery.initial_state_timeout` to `0` and wait for the cluster to form once all node have been started. Also, because a node may wait and ping while other nodes are started, `MockZenPing` is adapted to wait rather than busy-ping.

Jason Tedor 491a945ac8 Add socket permissions for tribe nodes
Today when a node starts, we create dynamic socket permissions based on
the configured HTTP ports and transport ports. If no ports are
configured, we use the default port ranges. When a tribe node starts, a
tribe node creates an internal node client for connecting to each remote
cluster. If neither an explicit HTTP port nor transport ports were
specified, the default port ranges are large enough for the tribe node
and its internal node clients. If an explicit HTTP port or transport
port was specified for the tribe node, then socket permissions for those
ports will be created, but not for the internal node clients. Whether
the internal node clients have explicit ports specified, or attempt to
bind within the default range, socket permissions for these will not
have been created and the internal node clients will hit a permissions
issue when attempting to bind. This commit addresses this issue by also
accounting for tribe nodes when creating the dynamic socket
permissions. Additionally, we add our first real integration test for
tribe nodes.

Jason Tedor d273419d00 Do not prematurely shutdown Log4j
When a node closes, we shutdown logging as the last statement. This
statement must be last lest any subsequent attempts to log will blow up
by running into security permissions. Yet, in the case of a tribe node
this isn't enough. The first internal tribe node to close will shutdown
logging, and subsequent node closes will blow up with the aforementioned
problem. This commit migrate the Log4j shutdown to occur as part of the
shutdown hook that closes the node, after all nodes have
closed. Consequently, we can remove a hack in the test infrastructure to
prevent Log4j shutdowns when internal test nodes close and instead just
register a single shutdown hook that runs when the test JVM exits.

We currently often use ensureGreen or ensureYellow to check whether the cluster is in a good state again after shutting down a node. With the change in #21092, however, it can happen that if the node that is stopped is the master node, another node will become master and publish a cluster state where it is master but where the node that was stopped hasn't been removed yet from the cluster state. It will only publish a second state thereafter where the old master is removed. If the ensureGreen/ensureYellow is timed just right, it will get to execute before the second cluster state update removing the old master and the condition ensureGreen / ensureYellow might not hold at that point anymore.

Jason Tedor f16c308efd Assert status logger does not warn on Log4j usage
Today if you start Elasticsearch with the status logger configured to
the warn level, or use a transport client with the default status logger
level, you will see warn messages about deprecation loggers being
created with different message factories and that formatting might be
broken. This happens because the deprecation logger is constructed using
the message factory from its parent, an artifact leftover from the first
Log4j 2 implementation that used a custom message factory. When that
custom message factory was removed, this constructor invocation should
have been changed to not explicitly use the message factory from the
parent. This commit fixes this invocation. However, we also had some
status checking to all tests to ensure that there are no warn status log
messages that might indicate a configuration problem with Log4j 2. These
assertions blow up badly without the fix for the deprecation logger
construction, and also caught a misconfiguration in one of the logging
tests.

Adrien Grand aa6cd93e0f Require arguments for QueryShardContext creation. (#21196)
The `IndexService#newQueryShardContext()` method creates a QueryShardContext on
shard `0`, with a `null` reader and that uses `System.currentTimeMillis()` to
resolve `now`. This may hide bugs, since the shard id is sometimes used for
query parsing (it is used to salt random score generation in `function_score`),
passing a `null` reader disables query rewriting and for some use-cases, it is
simply not ok to rely on the current timestamp (eg. percolation). So this pull
request removes this method and instead requires that all call sites provide
these parameters explicitly.

Simon Willnauer 43dbf9c7b6 Use all available hosts in REST tests and allow for real master election (#21161)
Today we only use a single node to send requests to when we run REST tests.
In some cases we have more than one node (ie. in the BWC case) where we should
send requests to all nodes in a round-robin fashion. This change passes all
available node endpoints to the rest test.

Additionally, this change adds the setting of `discovery.zen.minimum_master_nodes`
to the cluster formation forcing the nodes to wait for all other nodes until the cluster
is formed. This allows for a more realistic master election and allows all master eligable
nodes to become master while before always the first node in the cluster became the master.

This also adds logging to each test run to log the master nodes version and the minimum node
version in the cluster to help debugging BWC test failures.

Simon Willnauer 97cc426a89 Fix bwc cluster formation in order to run BWC tests against a mixed version cluster (#21145)
This fixes our cluster formation task to run REST tests against a mixed version cluster.
Yet, due to some limitations in our test framework `indices.rollover` tests are currently
disabled for the BWC case since they select the current master as the merge node which
happens to be a BWC node and we can't relocate all shards to it since the primaries are on
a higher version node. This will be fixed in a followup.

Closes #21142

Note: This has been cherry-picked from 5.0 and fixes several rest tests
as well as a BWC break in `OsStats.java`

This commit fixes responses to HEAD requests so that the value of the
Content-Length is correct per the HTTP spec. Namely, the value of this
header should be equal to the Content-Length if the request were not a
HEAD request.

This commit also fixes a memory leak on HEAD requests to the main action
that arose from the bytes on a builder not being released due to them
being dropped on the floor to ensure that the response to the main
action did not have a body.

Today the request interceptor can't support async calls since the response

thread. This means in-turn that the intercepted handler is not executed with the
thread it was supposed to run and therefor can, if it's executing blocking
operations, potentially deadlock an entire server.

Boaz Leskes c3987156ab Remove local discovery in favor of a simpler `MockZenPings` (#20960)
`LocalDiscovery` is a discovery implementation that uses static in memory maps to keep track of current live nodes. This is used extensively in our tests in order to speed up cluster formation (i.e., shortcut the 3 second ping period used by `ZenDiscovery` by default). This is sad as that mean that most of the test run using a different discovery semantics than what is used in production. Instead of replacing the entire discovery logic, we can use a similar approach to only shortcut the pinging components.

Boaz Leskes eaa105951f Simplify GlobalCheckpointService and properly hook it for cluster state updates (#20720)
During a recent merge from master, we lost the bridge from IndicesClusterStateService to the GlobalCheckpointService of primary shards, notifying them of changes to the current set of active/initializing shards. This commits add the bridge back (with unit tests). It also simplifies the GlobalCheckpoint tracking to use a simpler model (which makes use the fact that the global check point sync is done periodically).

The old integration CheckpointIT test is moved to IndexLevelReplicationTests. I also added similar assertions to RelocationsIT, which surfaced a bug in the primary relocation logic and how it plays with global checkpoint updates. The test is currently await-fixed and will be fixed in a follow up issue.

Simon Willnauer 134b1f9b4d Prevent thread suspension when inside SecurityManager (#20770)
LongGCDisruption suspends and resumes node threads but respects several
`unsafe` class name patterns where it's unsafe to suspend. For instance
log4j uses a global lock so we can't suspend a thread that is currently
calling into log4j. The same is true for the security manager, it's similar
to log4j a shared resource between the test and the node that is _suspended_.
This change adds `java.lang.SecrityManager` to the unsafe patterns.
This prevents test framework deadlocking if a nodes thread is supended
while it's calling into the security manager that uses synchronized maps etc.

Boaz Leskes ee76c1a5c9 Remove NoopGatewayAllocator in favor of a more realistic mock (#20637)
Many of our unit tests instantiate an `AllocationService`, which requires having a `GatewayAllocator`. Today almost all of our test use a class called `NoopGatewayAllocator` which does nothing, effectively leaving all shard assignments to the balanced allocator. This is sad as it means we test a system that behaves differently than our production logic in very basic things. For example, a started primary that is lost will be assigned to a node that didn't use to have it.

This PR removes `NoopGatewayAllocator` in favor of a new `TestGatewayAllocator` that inherits the standard `GatewayAllocator` and overrides shard information fetching to return information based on historical assignments the allocator has done. The only exception is `BalanceConfigurationTests` which does test only the balancer and I opted to not have it work around the `GatewayAllocator` being in it's way.

Today we hold on to all possible tokenizers, tokenfilters etc. when we create
an index service on a node. This was mainly done to allow the `_analyze` API to
directly access all these primitive. We fixed this in #19827 and can now get rid of
the AnalysisService entirely and replace it with a simple map like class. This
ensures we don't create a gazillion long living objects that are entirely useless since
they are never used in most of the indices. Also those objects might consume a considerable
amount of memory since they might load stopwords or synonyms etc.

Ali Beyad 50584c4103 Merge pull request #20532 from rjernst/rolling_upgrades
This PR introduces backward compatibility index tests to test the rolling upgrade process amongst Elasticsearch instances within the same major version. The test executes in three phases. In the first phase, we form a cluster of 2 ES instances on an old version. In the second phase, we keep one of the nodes from the old cluster, kill the other node, but preserve its data directory and start an instance of the current version of ES using the same data directory as the killed instance. In the third phase, we kill the other old version ES instance from the first phase and launch a new instance, using the same data directory as the killed instance. Therefore, during phase 3, we have fully migrated and have all current versions of ES running. In each phase, we run REST tests that index documents and search them, ensuring at each stage that the documents from the previous phase are still there.

Note that because we haven't released a GA yet of 5.0, the tests currently don't start an old version cluster in the first phase. Once GA is released, this will be changed to make the backward compatibility version 5.0, while the current version in the cluster will be 5.x.

Boaz Leskes 2ee9ab25d9 Remove `RoutingAllocation.Result` (#20538)
Currently all the reroute-like methods of `AllocationService` return a result object of type `RoutingAllocation.Result`. The result object contains the new `RoutingTable` and `MetaData` plus an indication whether those were changed. The caller is then responsible of updating a cluster state with these. These means that things can easily go wrong and one can take one of these but not the other causing inconsistencies. We already have a utility method on the `ClusterState` builder that does but no one forces you to do so. Also 99% of the callers do the same thing: i.e., check if the result was changed and if so update the very same cluster state that was passed to `AllocationService`.  This PR folds this pattern into `AllocationService` and changes almost all it's methods to return a new cluster state (potentially the original one).  This saves some 500 lines of code.

The one exception here is the reroute API which executes allocation commands and potentially returns an explanation as well (next to the routing table and metadata). That API now returns a `CommandsResult` object which encapsulate a cluster state and the explanation.
