This commit configures test logging for Log4j 2. The default logger
configuration uses the console appender but at the error level, so most
tests are missing logging. Instead, this commit provides a configuration
for tests which is picked up from the classpath by Log4j 2 when it
initializes. However, this now means that we can no longer initialize
Log4j with a bare-bones configuration when tests run as doing so will
prevent Log4j 2 from attempting to configure logging via the
classpath. Consequently, we move this needed initialization (as
commented, to avoid a message about a status logger not being configured
when we are preparing to configure Log4j from properties files in the
config directory) to only run when we are explicitly configuring Log4j
from properties files.

If elasticsearch controls the ID values as well as the documents
version we can optimize the code that adds / appends the documents
to the index. Essentially we an skip the version lookup for all
documents unless the same document is delivered more than once.
On the lucene level we can simply call IndexWriter#addDocument instead
of #updateDocument but on the Engine level we need to ensure that we deoptimize
the case once we see the same document more than once.
This is done as follows:
1. Mark every request with a timestamp. This is done once on the first node that
receives a request and is fixed for this request. This can be even the
machine local time (see why later). The important part is that retry
requests will have the same value as the original one.
2. In the engine we make sure we keep the highest seen time stamp of "retry" requests.
This is updated while the retry request has its doc id lock. Call this `maxUnsafeAutoIdTimestamp`
3. When the engine runs an "optimized" request comes, it compares it's timestamp with the
current `maxUnsafeAutoIdTimestamp` (but doesn't update it). If the the request
timestamp is higher it is safe to execute it as optimized (no retry request with the same
timestamp has been run before). If not we fall back to "non-optimzed" mode and run the request as a retry one
and update the `maxUnsafeAutoIdTimestamp` unless it's been updated already to a higher value

* Params improvements to Cluster Health API wait for shards
Previously, the cluster health API used a strictly numeric value
for `wait_for_active_shards`. However, with the introduction of
ActiveShardCount and the removal of write consistency level for
replication operations, `wait_for_active_shards` is used for
write operations to represent values for ActiveShardCount. This
commit moves the cluster health API's usage of `wait_for_active_shards`
to be consistent with its usage in the write operation APIs.
This commit also changes `wait_for_relocating_shards` from a
numeric value to a simple boolean value `wait_for_no_relocating_shards`
to set whether the cluster health operation should wait for
all relocating shards to complete relocation.
* Addresses code review comments
* Don't be lenient if `wait_for_relocating_shards` is set

This commit adds an empty test to ESLoggerUsageTests to avoid the test

marked as awaits fix in 1d197eddcc.
This commit modifies the call sites that allocate a parameterized
message to use a supplier so that allocations are avoided unless the log
level is fine enough to emit the corresponding log message.
Rest test suites are currently only the directory above the yaml test
file. That is confusing when there are more than one directory level
which contain yaml tests, as there are in generated docs tests. This
change makes rest tests use the full relative path to the rest test root
as the suite name, and also makes the test names for docs tests a little
clearer (that they are testing an example from a specific line number,
instead of just the line number as an opaque test name).
Removed null check for token, if we are outside the null it already means it is null.
Fixed typo in comment and remove leftover assignment to unused local variable.
This test is periodically failing. As I suspect that the GCDisruption scheme is somehow making the wrong node block on
its cluster state update thread, I've added some more logging and a thread dump once the given assertion triggers
again.
Adds an explicit recoverySource field to ShardRouting that characterizes the type of recovery to perform:
- fresh empty shard copy
- existing local shard copy
- recover from peer (primary)
- recover from snapshot
- recover from other local shards on same node (shrink index action)
Objects hierarchy must be tracked when entering/leaving an object so that it better knows if the "newField" has been inserted into an arbitrary holding object.
Can be reproduced with gradle :core:test -Dtests.seed=760F8BD0F7E46D45 -Dtests.class=org.elasticsearch.index.query.MoreLikeThisQueryBuilderTests -Dtests.method="testUnknownObjectException" -Dtests.security.manager=true -Dtests.locale=ko -Dtests.timezone=Etc/Zulu
When need to check the whole hierarchy of objects to know if the newly inserted "newField" object is part of an arbitrary holding object or not.
Reproduced with `gradle :modules:percolator:test -Dtests.seed=736B0B67DA7A3632 -Dtests.class=org.elasticsearch.percolator.PercolateQueryBuilderTests -Dtests.method="testUnknownObjectException" -Dtests.security.manager=true -Dtests.locale=es-ES -Dtests.timezone=ART`
This method fails when a randomized string value contains a double-quote. This commit changes the method so that it is not based on string concatenation anymore. It now use XContentGenerator & XContentParser to mutate the valid queries.

This change adds a special field named _none_ that allows to disable the retrieval of the stored fields in a search request or in a TopHitsAggregation.
To completely disable stored fields retrieval (including disabling metadata fields retrieval such as _id or _type) use _none_ like this:
````
POST _search
{
"stored_fields": "_none_"
}
````
Deprecates the optimize_bbox parameter on geodistance queries. This has no longer been needed since version 2.2 because lucene geo distance queries (postings and LatLonPoint) already optimize by bounding box.
This change converts AllocationDecider registration from push based on
ClusterModule to implementing with a new ClusterPlugin interface.
AllocationDecider instances are allowed to use only Settings and
ClusterSettings.
Adds a class that records changes made to RoutingAllocation, so that at the end of the allocation round other values can be more easily derived based on these changes. Most notably, it:
- replaces the explicit boolean flag that is passed around everywhere to denote changes to the routing table. The boolean flag is automatically updated now when changes actually occur, preventing issues where it got out of sync with actual changes to the routing table.
- records actual changes made to RoutingNodes so that primary term and in-sync allocation ids, which are part of index metadata, can be efficiently updated just by looking at the shards that were actually changed.
In addition to be an allocation decider, DiskThresholdDecider also
monitors the used disk in order to trigger a reroute when the thresholds
are crossed. This change splits out the settings for disk thresholds
into DiskThresholdSettings, and moves the monitoring to a new
DiskThresholdMonitor. DiskThresholdDecider is then in line with other
allocation deciders, needing only Settings and ClusterSettings for
construction, which will allow deguicing allocation deciders.
`LobObtainFailedException` should be reserved for on-disk locks that
Lucene attempts (like `write.lock`). This switches our in-memory
semaphore locks for shards to use a different exception. Additionally,
ShardLockObtainFailedException no longer subclasses IOException, since
no IO is being done is this case.
Resolves#19978
As the most complicated `FetchSubPhase` highlighting gets its own package
(`o.e.seach.fetch.subphase.highlight`. No other `FetchSubPhase`s get their
own package. Instead they all reside together in `o.e.search.fetch.subphase`.
Add package descriptions to `o.e.search.fetch` and subpackages.
This commit defaults the max local storage nodes to one. The motivation
for this change is that a default value greather than one is dangerous
as users sometimes end up unknowingly starting a second node and start
thinking that they have encountered data loss.

This commit separates the description of the links in the network that are to be disrupted from the failure that is to be applied to the links (disconnect/unresponsive/delay). Previously we had subclasses for the various kind of network disruption schemes combining on one hand failure mode (disconnect/unresponsive/delay) as well as the network links to cut (two partitions / bridge partitioning) into a single class.
I also reduced the visibility of a couple classes and renamed/consolidated some
test classes for consistency, eg. removing the `Simple` prefix or using the
`<Type>FieldMapperTests` convention for testing field mappers.
testUnknownObjectException used to generate malformed json objects in some cases, due to the existence of arrays as it was not closing the injected object correctly. That is why the test was catching JsonParseException among the exception that are expected to be thrown. That is fixed by tracking where the new object is placed and placing its end object marker to the right level rather than always at the end.
Also introduced a mechanism to explicitly declare objects that won't cause any exception when they get additional objects injected, so that there is no need to override the method anymore as that caused copy pasting of the whole test method. This also makes sure that changes are reflected in tests, as those inner objects are not skipped but we actually check that what is declared is true (no exceptions get thrown when an additional object is added within them.
When compiling many dynamically changing scripts, parameterized
scripts (<https://www.elastic.co/guide/en/elasticsearch/reference/master/modules-scripting-using.html#prefer-params>)
should be preferred. This enforces a limit to the number of scripts that
can be compiled within a minute. A new dynamic setting is added -
`script.max_compilations_per_minute`, which defaults to 15.
If more dynamic scripts are sent, a user will get the following
exception:
```json

"root_cause" : [

"type" : "circuit_breaking_exception",
"reason" : "[script] Too many dynamic script compilations within one minute, max: [15/min]; please use on-disk, indexed, or scripts with parameters instead",

This also fixes a bug in `ScriptService` where requests being executed
concurrently on a single node could cause a script to be compiled
multiple times (many in the case of a powerful node with many shards)
due to no synchronization between checking the cache and compiling the
script. There is now synchronization so that a script being compiled
will only be compiled once regardless of the number of concurrent
searches on a node.

Some random operations were conditionally performed in the before test, which made tests not repeatable. For instance take the seed chain to repeat a specific iteration and try to reproduce it, this conditional code would get executed in both cases when trying to isolate the failure, but not among the different iterations (as only the first method/iteration executes it), hence the failure will not reproduce.
Moved the random operations to beforeClass and left the non random part in the before method, which is needed as it depends on some method that can be overridden by subclasses.
This commit cleans up indices in a snapshot repository when all
snapshots containing the index are all deleted. Previously, empty
indices folders would lay around after all snapshots containing
them were deleted.
