When proportioning the shared RAM bytes across the shards of the query
cache, there's a computation that shares these bytes according to the
relative size of the shard cache to the total size of all the shard
caches. This computation had a bug where integer division was performed
instead which leads to this computation often being zero. This commit
fixes this bug by casting the numerator to a double before doing the
division so that double division is performed.

The Lucene version expectation in the verify Lucene version test is
backwards, mixing up the expected and actual values. This commit
reorders them to fix this issue.
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.

This commit fixes a double decrement bug on the current query
counter. The double decrement arises in a situation when the fetch phase
is inlined for a query that is only touching one shard. After the query
phase succeeds we decrement the current query counter. If the fetch
phase ultimately fails, an exception is thrown and we decrement the
current query counter again in the catch block. We also add assertions
that all current stats counters remain non-negative at all
times.

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.
In #23093 we made a change so that total bytes for a filesystem would not be a
negative value when the total bytes were > Long.MAX_VALUE.
This fixes#24453 which had a related issue where `available` and `free` bytes
could also be so large that they were negative. These will now return
`Long.MAX_VALUE` for the bytes if the JDK returns a negative value.
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.
This commit fixes an issue with the plugin docs incorrectly specifying
how to set a custom configuration directory. The correct way is to use
the environment variable CONF_DIR.
This commit renames the concept of the "compiled type" to a "factory
type", along with all implementations of this class to be named Factory.
This brings it inline with the classes purpose.
This commit adds collection of all contexts to the parameters of
getScriptEngine. This will allow script engines like painless to
precache extra information about the contexts.
This test is failing sporadically and for now we mute it as we have a
failure with additional logging that should hopefully enable us to
assess the situation.
When transitive dependencies are disable for a dependency, gradle adds a
wildcard exclusion to the generated pom. However, some external tools
like ivy have bugs with wildcards. This commit adds back the explicit
generation of transitive excludes, and removes the gradle generated
exclusions element from the pom.

This is a simple refactoring to move the context definitions into the
type that they use. While we have multiple context names for the same
class at the moment, this will eventually become one ScriptContext per
instance type, so the pattern of a static member on the interface called
CONTEXT can be used. This commit also moves the consolidated list of
contexts provided by core ES into ScriptModule.
This commit fixes the error message to escape the dollar sign for
referencing a literal `$HADOOP_HOME`, which caused an error while trying
to generate an error.
closes#24878
This change cleans up some missed TODOs for content type detection on the source of put mapping and
put index template requests. In 5.3.0 and newer versions, the source is always JSON so the content
type detection is not needed. The TODOs were missed after the change was backported to 5.3.

This commit adds the ability to store and retrieve data that should be associated with a
ScrollContext. Additionally the ScrollContext was made final as we should only have a single
implementation of this concept.
This commit changes the compile method of ScriptEngine to be generic in
the same way it is on ScriptService. This moves the shim of handling the
two existing context classes into each script engine, so that each
engine can be worked on independently to convert to real handling of
contexts.
When developing the new ScriptContext, the compiled type was original
generic, so that the instance type was also necessary. However, since
CompiledType is all that is used by the compile method signature, we
actually don't need the instance type to be generic. This commit removes
the InstanceType, and finds the Class for it through reflection on the
CompiledType method.
This commit modifies the compile method of ScriptService to be context
aware. The ScriptContext is now a generic class which contains both the
instance type and compiled type for a script. Instance type may be
stateful (for example, pre loading field information for the index a
script will execute on, like in expressions), while the compiled type is
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.
Since groovy was removed, we no longer have any ScriptEngines with
resources to release. We may want to keep the option open for a script
engine to close resources, but this would not be common. This commit
adds a default implementation to ScriptEngine for `close()` to reduce
the boiler plate that must be added for a ScriptEngine implementation.
Some packaging tests depend on snapshot versions of packaging
distributions yet the build does not use a repository that includes such
distributions. While we could add such a repository, a better strategy
is to follow our approach for other BWC tests where we depend on a
locally-compiled archive distribution. This commit adds a local
compilation of packaging artifacts and substitutes these anywhere that
we would otherwise depend on a snapshot of these artifacts.

This commit increases the logging level on the index and relocate
concurrently test to obtain some insight into the global checkpoint
moving backwards.
The current log tries make sure we waited some (but not too long). This is unpredictable and fails all the time. This commit removes all of it and just make sure that we throw the right exceptions after timing out.
Fixes#24369
* SignificantText aggregation - like significant_terms but doesn’t require fielddata=true, recommended used with `sampler` agg to limit expense of tokenizing docs and takes optional `filter_duplicate_text`:true setting to avoid stats skew from repeated sections of text in search results.
Closes#23674
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.

This commit cleans up tests which currently use custom script engine
implementations, converting them to use a MockScriptEngine with script
functions provided by the tests. It also creates a common set of metric
scripts which were copied across a couple metric agg tests.
Large test suites with unfortunate seed choices can easily exceed the
1000 script compilations per minute limit. This commit increases the
limit in integration tests to 2048.
Adds a "magic" key to the yaml testing stash mostly for use with
documentation tests. When unstashing an object, `$_path` is the
path into the current position in the object you are unstashing.
This means that in docs tests you can use
`// TESTRESPONSEs/somevalue/$body.${_path}/` to mean "replace
`somevalue` with whatever is the response in the same position."
Compare how you must carefully mock out all the numbers in the profile
response without this change:
```

```
// TESTRESPONSE[s/(?<=[" ])\d+(\.\d+)?/$body.$_path/]
```
A user reported uneven balancing of load on nodes handling search requests from Kibana which supplies a session ID in a routing preference. Each shardId was selecting the same node for a given session ID because one data node had all primaries and the other data node held all replicas after cluster startup.
This change counteracts the tendency to opt for the same node given the same user-supplied preference by incorporating shard ID in the hash of the preference key. This will help randomise node choices across shards.
Closes#24642
This commit adds comments to org.elasticsearch.Assertions that disables
IntelliJ from complaining about using assert with side-effects, and
using constant conditions there as the side-effect with a constant
condition is intentionally employed.
