This commit refactors the handling of thread pool settings so that the
individual settings can be registered rather than registering the top
level group. With this refactoring, individual plugins must now register
their own settings for custom thread pools that they need, but a
dedicated API is provided for this in the thread pool module. This
commit also renames the prefix on the thread pool settings from
"threadpool" to "thread_pool". This enables a hard break on the settings
so that:
- some of the settings can be given more sensible names (e.g., the max
number of threads in a scaling thread pool is now named "max" instead
of "size")
- change the soft limit on the number of threads in the bulk and
indexing thread pools to a hard limit
- the settings names for custom plugins for thread pools can be
prefixed (e.g., "xpack.watcher.thread_pool.size")
- remove dynamic thread pool settings
Relates #18674
This adds support for setting the refresh request parameter to
`wait_for` in the `index`, `delete`, `update`, and `bulk` APIs. When
`refresh=wait_for` is set those APIs will not return until their
results have been made visible to search by a refresh.
Also it adds a `forced_refresh` field to the response of `index`,
`delete`, `update`, and to each item in a bulk response. This will
be true for requests with `?refresh` or `?refresh=true` and will be
true for some requests (see below) with `refresh=wait_for` but ought
to otherwise always be false.
`refresh=wait_for` is implemented as a list of
`Tuple<Translog.Location, Consumer<Boolean>>`s in the new `RefreshListeners`
class that is managed by `IndexShard`. The dynamic, index scoped
`index.max_refresh_listeners` setting controls a maximum number of
listeners allowed in any shard. If more than that many listeners
accumulate in the engine then a refresh will be forced, the thread that
adds the listener will be blocked until the refresh completes, and then the
listener will be called with a `forcedRefresh` flag so it knows that it was
the "straw that broke the camel's back". These listeners are only used by
`refresh=wait_for` and that flag manifests itself as `forced_refresh` being
`true` in the response.
About half of this change comes from piping async-ness down to the appropriate
layer in a way that is compatible with the ongoing with with sequence ids.

Handle hanging documents
If a document is added to the index during a refresh we weren't properly
firing its refresh listener. This happened because the way we detect
whether a refresh makes something visible or not is imperfect. It is
ok because it always errs on the side of thinking that something isn't
yet visible.
So when a document arrives during a refresh the refresh listeners
won't think it made it into a refresh when, often, it does. The way
we work around this is by telling Elasticsearch that it ought to
trigger a refresh if there are any pending refresh listeners even
if there aren't pending documents to update. Lucene short circuits
the refresh so it doesn't take that much effort, but the refresh
listeners still get the signal that a refresh has come in and they
still pick up the change and notify the listener.
This means that the time that a listener can wait is actually slightly
longer than the refresh interval.

Remove Translog#lastWriteLocation
I wasn't being careful enough with locks so it wasn't right anyway.
Instead this builds a synthetic Tranlog.Location when you call
getWriteLocation with much more relaxed equality guarantees. Rather
than being equal to the last Translog.Location returned it is
simply guaranteed to be greater than the last translog returned
and less than the next.

Move refresh listeners into their own class
They still live at the IndexShard level but they live on their
own in RefreshListeners which interacts with IndexShard using a
couple of callbacks and a registration method. This lets us test
the listeners without standing up an entire IndexShard. We still
test the listeners against an InternalEngine, because the interplay
between InternalEngine, Translog, and RefreshListeners is complex
and important to get right.

Never reply to replica actions while you have the operation lock
This last thing was causing periodic test failures because we were
replying while we had the operation lock. Now, we probably could get
away with that in most cases but the tests don't like it and it isn't
a good idea to do network io while you have a lock anyway. So this
prevents it.

Create ReplicatedMutationRequest
Superclass for index, delete, and bulkShard requests.
commit 0f8fa846a2822c4293df32fed18c9b99660b39ff
Author: Nik Everett <nik9000@gmail.com>
Date: Fri Apr 22 16:10:30 2016 -0400
Create TransportReplicatedMutationAction
It is the superclass of replication actions that mutate data: index, delete,
and shardBulk. shardFlush and shardRefresh are replication actions but they
do not extend TransportReplicatedMutationAction because they don't change
the data, only shuffle it around.
Currently we support empty query clauses like the filter in
"constant_score" : { "filter" : { } }
How these clauses are handled depends on the surrounding query.
They later are either ignored, converted to match all or no documents or
passed up further in the query hierarchy. During parsing these claues are
currently represented as EmptyQueryBuilders. When not handled anywhere else,
these special cases need to be checked for on the shard when building the
lucene query.
This is trappy, so this PR changes the parsing of compound queries. Instead
of returning QueryBuilder, the core query parsing method
QueryShardContext#parseInnerQueryBuilder() now return an Optional which can
be empty in the case of empty query clauses. This has the advantage of forcing
callers to deal with this sooner or later. When encountering empty Optionals,
compound query builders now have the choice to ignore them, pass them on or
rewrite to a different query, depending on context.
This commit adds a new aggs-matrix-stats module. The module presents a new class of aggregations called Matrix Aggregations. Matrix aggregations work on multiple fields and produce a matrix as output. The first matrix aggregation provided by the module is matrix_stats aggregation. This aggregation computes the following statistics over a set of fields:
* Covariance
* Correlation
For completeness (and interpretation purposes) the following per-field statistics are also provided:
* sample count
* population mean
* population variance
* population skewness
* population kurtosis
Similar reasoning as #18133 but for the aggs API. One important change is that
I moved the base PipelineAggregatorBuilder class to the o.e.s.aggregations
package instead of o.e.s.aggregations.pipeline so that the create method does
not need to be public.
There is no reason to read the entire marvel hero file to test the features,
it might take several seconds to do so which is unnecessary.
This commit also splits SearchSuggestTests into core and modules/mustache
also add @Nighlty to forbidden API to make sure we don't use it since they won't run in CI these days.
- now you can specify a list of grok patterns to match your field with
and the first one to successfully match wins.
- only non-null captures will be inserted into your matched document.
Fixes#17903.
Significant changes:
* AbstractQueryTestCase has moved to the test framework module, in order for query builder tests in modules and plugins
* Added support to AbstractQueryTestCase to register plugins
* Lift the restriction that only one percolator could be added per index. This validation existed in MapperService, but because the percolator moved to a module it could no longer exist there. Instead of bringing it back it was removed. This validation existed since the percolator cache only supported one percolator query per document, since the percolator cache has been removed this restriction could removed as well.
* While moving percolator tests to the new module, also removed a couple of tests for the deprecated percolate and mpercolate api. These APIs are now sugar APIs for bwc and rediect to the searvh and msearvh APIs. Some tests were still testing as if percolate and mpercolate API did the percolation, but this no longer the case and these tests could be removed.
The assertBusy method currently has both a Runnable and Callable
version. This has caused confusion with type inference and lambdas
sometimes, in particular with java 9. This change removes the callable
version as nothing was actually using it.
The retry test has failed a couple of times in CI because it wasn't able
to cause any retries. Putting it in a bash `while` loop shows that it
eventually does fail that way. The seed "4F6477A9C999CA20" seems especially
good at failing to get retries. It doesn't fail all the time, but more
than most.
This adds a retry to each test case, retrying a maximum of 10 times or
until it causes the retries. I've seen it fail to get retries 7 times
in a row but not go beyond that. Retrying doesn't seem to really hurt
the test runtime all that much. Most of the time is in the startup
cost.
Failing CI build that triggered this:
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+master+periodic/852/console
This change makes ES compile with java9 again, build 118.
* There are a handful of changes due to failure to determine types during compile.
* The attachment plugins which use tika needed to have tika upgraded in order to pickup fixes there for java 9.
* azure discovery and s3 repository indirectly depend on jaxb, which is no longer in the default modules. They now add a jaxb dependency externally, and make JarHell allow for this package.
This removes the ScriptMode class entirely, which was an enum with two
options (ON and OFF) which essentially boiled down to true and false.
Now the boolean values are used instead.
Before 5.0 for it was required that the percolator queries were cached in jvm heap as Lucene queries for two reasons:
1) Performance. The percolator evaluated all percolator queries all the time. There was no pre-selecting queries that are likely to match like we have today.
2) Updates made to percolator queries were visible in realtime, Today these changes are visible in near realtime. So updating no longer requires the percolator to have the queries in jvm heap.
So having the percolator queries in jvm heap via the percolator cache is now less attractive. Especially when there are many percolator queries then these queries can consume many GBs of jvm heap.
Removing the percolator cache does make the percolate query slower compared to how the execution time in 5.0.0-alpha1 and alpha2, but it is still faster compared to 2.x and before.
Please note: The maps inside the pirvate singleton instance of Defininition are no longer unmodifiable, but nothing from the outside can modify it! All private :-)
This uses the same backoff policy we use for bulk and just retries until
the request isn't rejected.
Instead of `{"retries": 12}` in the response to count retries this now
looks like `{"retries": {"bulk": 12", "search": 1}`.

painless: add method overloading based on arity
Previously multiple extensions could be provided, however, this can lead
to confusion with on-disk scripts (ie, "foo.js" and "foo.javascript")
having different content. Only a single extension is now supported.
The only language currently supporting multiple extensions was the
Javascript engine ("js" and "javascript"). It now only supports the
`.js` extension.
Relates to #10598
This removes all the mentions of the sandbox from the script engine
services and permissions model. This means that the following settings
are no longer supported:
```yaml
script.inline: sandbox
script.stored: sandbox
```
Instead, only a `true` or `false` value can be specified.
Since this would otherwise break the default-allow parameter for
languages like expressions, painless, and mustache, all script engines
have been updated to have individual settings, for instance:
```yaml
script.engine.groovy.inline: true
```
Would enable all inline scripts for groovy. (they can still be
overridden on a per-operation basis).
Expressions, Painless, and Mustache all default to `true` for inline,
file, and stored scripts to preserve the old scripting behavior.
Resolves#17114
We add support to explicitly exclude specific transport actions
from the request size limit check.
We also exclude the following request types currently:
*MasterPingRequest
* PingRequest
Remove performance hack for accessing a document's fields, its not needed.

Closes#18201
Most of the current implementations of BaseNodesResponse (plural Nodes) ignore FailedNodeExceptions.
- This adds a helper function to do the grouping to TransportNodesAction
- Requires a non-null array of FailedNodeExceptions within the BaseNodesResponse constructor
- Reads/writes the array to output
- Also adds StreamInput and StreamOutput methods for generically reading and writing arrays
QueryBuilder has generics, but those are never used: all call sites use
`QueryBuilder<?>`. Only `AbstractQueryBuilder` needs generics so that the base
class can contain a default implementation for setters that returns `this`.
This gives better coverage and consistency with the scripting APIs, by
whitelisting the primary search scripting API classes and using them instead
of only Map and List methods.
For example, accessing fields can now be done with `.value` instead of `.0`
because `getValue()` is whitelisted. For now, access to a document's fields in
this way (loads) are fast-pathed in the code, to avoid dynamic overhead.
Access to geo fields and geo distance functions is now supported.

Painless: add fielddata accessors (.value/.values/.distance()/etc)
This commit introduces a handshake when initiating a light
connection. During this handshake, node information, cluster name, and
version are received from the target node of the connection. This
information can be used to immediately validate that the target node is
a member of the same cluster, and used to set the version on the
stream. This will allow us to extend APIs that are used during initial
cluster recovery without a major version change.

Add Simple round trip test for rethrottle request
The query shard reset() method resets some internal state in the
query shard context, like clearing query names, the filter flag
or named queries. The problem with this method being public is
that it currently (miss?) used for modifying an existing context
for recursive invocatiob, but the contexts that have been reseted
that way cannot be properly set back to their previous state.
This PR is a step towards removing reset() entirely by first making
it only be used internally in QueryShardContext. In places where
reset() was used we can either create new QueryShardContexts or
modify the existing context because it is discarded afterwards anyway.
Do this by creating a Client subclass that automatically assigns the
parentTask to all requests that come through it. Code that doesn't want
to set the parentTask can call `unwrap` on the Client to get the inner
client instance that doesn't set the parentTask. Reindex uses this for
its ClearScrollRequest so that the request will run properly after the
reindex request has been canceled.
Now that the current uses of magical camelCase support have been
deprecated, we can remove these in master (sans remaining issues like
BulkRequest). This change removes camel case support from ParseField,
query types, analysis, and settings lookup.
see #8988
Callers should explicitly handle parents - either using EMPTY_TASK_ID when
a parent isn't possible or piping parents from the TransportRequest when
possible.
This change cleans up a few things in QueryParseContext and QueryShardContext
that make it hard to reason about the state of these context objects and are
thus error prone and should be simplified.
Currently the parser that used in QueryParseContext can be set and reset any
time from the outside, which makes reasoning about it hard. This change makes
the parser a mandatory constructor argument removes ability to later set a
different ParseFieldMatcher. If none is provided at construction time, the
one set inside the parser is used. If a ParseFieldMatcher is specified at
construction time, it is implicitely set on the parser that is beeing used.
The ParseFieldMatcher is only kept inside the parser.
Also currently the QueryShardContext historically holds an inner QueryParseContext
(in the super class QueryRewriteContext), that is mainly used to hold the parser
and parseFieldMatcher. For that reason, the parser can also be reset, which leads
to the same problems as above. This change removes the QueryParseContext from
QueryRewriteContext and removes the ability to reset or retrieve it from the
QueryShardContext. Instead, `QueryRewriteContext#newParseContext(parser)` can be
used to create new parse contexts with the given parser from a shard context
when needed.
Currently we are able to set a ParseFieldMatcher on XContentParsers,
mainly to conveniently carry it around to be available where the
actual parsing happens. This was just recently introduced together
with ObjectParser so that ObjectParser can make use of deprecation
logging and throwing errors while parsing.
This however is trappy because we create parsers in so many places in
the code and it is easy to forget setting the right ParseFieldMatcher.
Instead we should hold the ParseFieldMatcher only in the parse contexts
(e.g. QueryParseContext).
This PR removes the ParseFieldMatcher from XContentParser. ObjectParser
can still make use of it because we can make the otherwise unbounded
`context` type to extend an interface that makes sure contexts used in
ObjectParser can supply a ParseFieldMatcher. Contexts in ObjectParser
are now no longer optional, but it is sufficient to pass in a small
lambda expression in places where no other context is available.
Relates to #17417
This makes all numeric fields including `date`, `ip` and `token_count` use
points instead of the inverted index as a lookup structure. This is expected
to perform worse for exact queries, but faster for range queries. It also
requires less storage.
Notes about how the change works:
- Numeric mappers have been split into a legacy version that is essentially
the current mapper, and a new version that uses points, eg.
LegacyDateFieldMapper and DateFieldMapper.
- Since new and old fields have the same names, the decision about which one
to use is made based on the index creation version.
- If you try to force using a legacy field on a new index or a field that uses
points on an old index, you will get an exception.
- IP addresses now support IPv6 via Lucene's InetAddressPoint and store them
in SORTED_SET doc values using the same encoding (fixed length of 16 bytes
and sortable).
- The internal MappedFieldType that is stored by the new mappers does not have
any of the points-related properties set. Instead, it keeps setting the index
options when parsing the `index` property of mappings and does
`if (fieldType.indexOptions() != IndexOptions.NONE) { // add point field }`
when parsing documents.
Known issues that won't fix:
- You can't use numeric fields in significant terms aggregations anymore since
this requires document frequencies, which points do not record.
- Term queries on numeric fields will now return constant scores instead of
giving better scores to the rare values.
Known issues that we could work around (in follow-up PRs, this one is too large
already):
- Range queries on `ip` addresses only work if both the lower and upper bounds
are inclusive (exclusive bounds are not exposed in Lucene). We could either
decide to implement it, or drop range support entirely and tell users to
query subnets using the CIDR notation instead.
- Since IP addresses now use a different representation for doc values,
aggregations will fail when running a terms aggregation on an ip field on a
list of indices that contains both pre-5.0 and 5.0 indices.
- The ip range aggregation does not work on the new ip field. We need to either
implement range aggs for SORTED_SET doc values or drop support for ip ranges
and tell users to use filters instead. #17700Closes#16751Closes#17007Closes#11513
When we pass down both parser and QueryParseContext to a method, we cannot
make sure that the parser contained in the context and the parser that is
parsed as an argument have the same state. This removes the parser argument
from methods where we currently have both the parser and the parse context
as arguments and instead retrieves the parse from the context inside the
method.
* Inner hits can now only be provided and prepared via setter in the nested, has_child and has_parent query.
* Also made `score_mode` a required constructor parameter.
* Moved has_child's min_child/max_children validation from doToQuery(...) to a setter.
This commit removes `MappedFieldType.value` and simplifies
`MappedFieldType.valueforSearch`. `valueforSearch` was used to post-process
values that come for stored fields (eg. to convert a long back to a string
representation of a date in the case of a date field) and also values that
are extracted from the source but only in the case of GET calls: it would
not be called when performing source filtering on search requests.
`valueforSearch` is now only called for stored fields, since values that are
extracted from the source should already be formatted as expected.
In both cases, what elasticsearch is really interested in is whether the field
is an analyzed string field. So it can just check `tokenized()` instead.
* upgrades numerics to new Point format
* updates geo api changes
* adds GeoPointDistanceRangeQuery as XGeoPointDistanceRangeQuery
* cuts over to ES GeoHashUtils
We have both `Settings.settingsBuilder` and `Settings.builder` that do exactly
the same thing, so we should keep only one. I kept `Settings.builder` since it
has my preference but also it is the one that we use in examples of the Java API.
Because sigma is also used at reduce time, it should be passed to empty aggs.
Otherwise it causes bugs when an empty aggregation is used to perform reduction
is it would assume a sigma of zero.
Closes#17362
This removes PROTOTYPEs from ScoreFunctionsBuilders. To do so we rework
registration so it doesn't need PROTOTYPEs and lines up with the recent
changes to query registration.
FieldStatsProvider had to perform instanceof calls to properly handle dates or
ip addresses. By moving the logic to MappedFieldType, each field type can check
whether all values are within bounds its way.
Note that this commit only keeps rewriting support for dates, which are the only
field for which the rewriting mechanism is likely to help (because of time-based
indices).
BulkByScrollTaskTest#testDelayAndRethrottle was getting rejected exceptions
every once in a while. This was reproducible ~20% of the time for me. I
added a CyclicBarrier to prevent the test from shutting down the thread pool
before the threads get finished.
This allows the user to update the reindex throttle on the fly, with changes
that speed up the throttling being applied immediately and changes that
slow down the throttling being applied during the next batch. This means
that if a user throttles reindex in such a way that it tries to sleep for
16 years and then realizes that they've done something wrong then they
can change the throttle and reindex will wake up again. We don't apply
slow downs immediately so we never get in danger of losing the scan context.
Also, if reindex is canceled while it is sleeping (how it honor throttling)
then it'll immediately wake up and cancel itself.
`text` fields will have fielddata disabled by default. Fielddata can still be
enabled on an existing index by setting `fielddata=true` in the mappings.
If a terms aggregation was ordered by a metric nested in a single bucket aggregator which did not collect any documents (e.g. a filters aggregation which did not match in that term bucket) an ArrayOutOfBoundsException would be thrown when the ordering code tried to retrieve the value for the metric. This fix fixes all numeric metric aggregators so they return their default value when a bucket ordinal is requested which was not collected.
