Jay Modi 3edadfefd0 RestHandlers declare handled routes (#52123)
This commit changes how RestHandlers are registered with the
RestController so that a RestHandler no longer needs to register itself
with the RestController. Instead the RestHandler interface has new
methods which when called provide information about the routes
(method and path combinations) that are handled by the handler
including any deprecated and/or replaced combinations.

This change also makes the publication of RestHandlers safe since they
no longer publish a reference to themselves within their constructors.

Closes #51622

Now that the FIPS 140 security provider is simply a test dependency
we don't need the thirdPartyAudit exceptions, but plugin-cli and
transport-netty4 do need jarHell disabled as they use the non fips
BouncyCastle security provider as a test dependency too.

[7.x] Improve Painless compilation performance for nested conditionals (#52056) (#52074)
* Improve Painless compilation performance for nested conditionals (#52056)

This PR changes how conditional expression is handled in `PainlessParser`
in a way that avoids the need for backtracking, which led to exponential
compilation times in case of nested conditionals.

The test was added ensures that we can compile deeply nested conditionals.

Deprecate creation of dot-prefixed index names except for hidden and system indices (#49959)
This commit deprecates the creation of dot-prefixed index names (e.g.
.watches) unless they are either 1) a hidden index, or 2) registered by
a plugin that extends SystemIndexPlugin. This is the first step
towards more thorough protections for system indices.

This commit also modifies several plugins which use dot-prefixed indices
to register indices they own as system indices, and adds a plugin to
register .tasks as a system index.

Enable tests in FIPS 140 in JDK 11 (#49485)
This change changes the way to run our test suites in 
JVMs configured in FIPS 140 approved mode. It does so by:

- Configuring any given runtime Java in FIPS mode with the bundled
policy and security properties files, setting the system
properties java.security.properties and java.security.policy
with the == operator that overrides the default JVM properties
and policy.

- When runtime java is 11 and higher, using BouncyCastle FIPS 
Cryptographic provider and BCJSSE in FIPS mode. These are 
used as testRuntime dependencies for unit
tests and internal clusters, and copied (relevant jars)
explicitly to the lib directory for testclusters used in REST tests

- When runtime java is 8, using BouncyCastle FIPS 
Cryptographic provider and SunJSSE in FIPS mode. 

Running the tests in FIPS 140 approved mode doesn't require an
additional configuration either in CI workers or locally and is
controlled by specifying -Dtests.fips.enabled=true

* Refactor ForEachProcessor to use iteration instead of recursion

This change makes ForEachProcessor iterative and still non-blocking.
In case of non-async processors we use single for loop and no recursion at all.
In case of async processors we continue work on either current thread or thread
started by downstream processor, whichever is slower (usually processor thread).
Everything is synchronised by single atomic variable.

Scripting: Add char position of script errors (#51069) (#51266)
Add the character position of a scripting error to error responses.

The contents of the `position` field are experimental and subject to
change.  Currently, `offset` refers to the character location where the
error was encountered, `start` and `end` define a range of characters
that contain the error.

eg.
```
{
  "error": {
    "root_cause": [
      {
        "type": "script_exception",
        "reason": "runtime error",
        "script_stack": [
          "y = x;",
          "     ^---- HERE"
        ],
        "script": "def x = new ArrayList(); Map y = x;",
        "lang": "painless",
        "position": {
          "offset": 33,
          "start": 29,
          "end": 35

Add "did you mean" to unknown queries (#51177) (#51254)
This replaces the message we return for unknown queries with the standard

because it includes "did you mean". One day we might convert parsing
queries to using object parser, but that looks complex. This change is
much smaller and seems useful.

Fix caching for PreConfiguredTokenFilter (#50912) (#51091)
The PreConfiguredTokenFilter#singletonWithVersion uses the version
internally for the token filter factories but it registers only one
instance in the cache and not one instance per version. This can lead
to exceptions like the one described in #50734 since the singleton is
created and cached using the version created of the first index
that is processed.

Remove the singletonWithVersion() methods and use the
elasticsearchVersion() methods instead.

Add "did you mean" to ObjectParser (#50938) (#50985)
Check it out:
```
$ curl -u elastic:password -HContent-Type:application/json -XPOST localhost:9200/test/_update/foo?pretty -d'{
  "dac": {}
}'

{
  "error" : {
    "root_cause" : [
      {
        "type" : "x_content_parse_exception",
        "reason" : "[2:3] [UpdateRequest] unknown field [dac] did you mean [doc]?"
      }
    ],
    "type" : "x_content_parse_exception",
    "reason" : "[2:3] [UpdateRequest] unknown field [dac] did you mean [doc]?"
  },
  "status" : 400
}
```

The tricky thing about implementing this is that x-content doesn't
depend on Lucene. So this works by creating an extension point for the
error message using SPI. Elasticsearch's server module provides the
"spell checking" implementation.

Alan Woodward 4974f56b25 Fix analysis BWC tests - warnings now emitted on index creation 2020-01-14 14:48:40 +00:00
Alan Woodward 8c16725a0d Check for deprecations when analyzers are built (#50908)
Generally speaking, deprecated analysis components in elasticsearch will issue deprecation
warnings when they are first used. However, this means that no warnings are emitted when
indexes are created with deprecated components, and users have to actually index a document
to see warnings. This makes it much harder to see these warnings and act on them at
appropriate times.

This is worse in the case where components throw exceptions on upgrade. In this case, users
will not be aware of a problem until a document is indexed, instead of at index creation time.

This commit adds a new check that pushes an empty string through all user-defined analyzers
and normalizers when an IndexAnalyzers object is built for each index; deprecation warnings
and exceptions are now emitted when indexes are created or opened.

Christoph Büscher b1b4282273 Make Multiplexer inherit filter chains analysis mode (#50662)
Currently, if an updateable synonym filter is included in a multiplexer filter,
it is not reloaded via the _reload_search_analyzers because the multiplexer
itself doesn't pass on the analysis mode of the filters it contains, so its not
recognized as "updateable" in itself. Instead we can check and merge the
AnalysisMode settings of all filters in the multiplexer and use the resulting
mode (e.g. search-time only) for the multiplexer itself, thus making any synonym
filters contained in it reloadable.  This, of course, will also make the
analyzers using the multiplexer be usable at search-time only.

Add per-field metadata. (#50333)
This PR adds per-field metadata that can be set in the mappings and is later
returned by the field capabilities API. This metadata is completely opaque to
Elasticsearch but may be used by tools that index data in Elasticsearch to
communicate metadata about fields with tools that then search this data. A
typical example that has been requested in the past is the ability to attach
a unit to a numeric field.

In order to not bloat the cluster state, Elasticsearch requires that this
metadata be small:
 - keys can't be longer than 20 chars,
 - values can only be numbers or strings of no more than 50 chars - no inner
   arrays or objects,
 - the metadata can't have more than 5 keys in total.

Given that metadata is opaque to Elasticsearch, field capabilities don't try to
do anything smart when merging metadata about multiple indices, the union of
all field metadatas is returned.

Here is how the meta might look like in mappings:

```json
{
  "properties": {
    "latency": {
      "type": "long",
      "meta": {
        "unit": "ms"
      }
    }
  }
}
```

And then in the field capabilities response:

```json
{
  "latency": {
    "long": {
      "searchable": true,
      "aggreggatable": true,
      "meta": {
        "unit": [ "ms" ]
      }
    }
  }
}
```

When there are no conflicts, values are arrays of size 1, but when there are
conflicts, Elasticsearch includes all unique values in this array, without
giving ways to know which index has which metadata value:

```json
{
  "latency": {
    "long": {
      "searchable": true,
      "aggreggatable": true,
      "meta": {
        "unit": [ "ms", "ns" ]
      }
    }
  }
}
```

Alan Woodward a3ab7eb95d Correctly handle MSM for nested disjunctions (#50669)
With the rewrite of the percolator's QueryAnalyzer to use lucene's QueryVisitor API,
term queries that are direct children of a boolean query are handled separately from
other children. This works fine for conjunctions, but for disjunctions we need to
treat the extracted terms from these direct descendents along with extractions from
more deeply nested children to ensure that minimum-should-match requirements
are met correctly.

This commit changes the logic in QueryAnalyzer#getResult() to bundle child term
results with all other results before handling them.

users to continue using Exception as "minimum" type for catch blocks, but 
for us to internally catch Error/Throwable. This is a required step to 
removing custom try/catch blocks from SClass.

Alan Woodward 3d8c2f9e18 Fix query analyzer logic for mixed conjunctions of terms and ranges (#49803)
When the query analyzer examines a conjunction containing both terms and ranges,
it should only include ranges in the minimum_should_match calculation if there are no
other range queries on that same field within the conjunction. This is because we cannot
build a selection query over disjoint ranges on the same field, and it is not easy to check
if two range queries have an overlap.

The current logic to calculate this just sets minimum_should_match to 1 or 0, dependent
on whether or not the current range is over a field that has already been seen. However, this
can be incorrect in the case that there are terms in the same match group which adjust the
minimum_should_match downwards. Instead, the logic should be changed to match the
terms extraction, whereby we adjust minimum_should_match downwards if we have already
seen a range field.

Scripting: Groundwork for caching script results (#49895) (#49944)
In order to cache script results in the query shard cache, we need to
check if scripts are deterministic.  This change adds a default method
to the script factories, `isResultDeterministic() -> false` which is
used by the `QueryShardContext`.

Script results were never cached and that does not change here.  Future
changes will implement this method based on whether the results of the
scripts are deterministic or not and therefore cacheable.

Zachary Tong fec882a457 Decouple pipeline reductions from final agg reduction (#45796)
Historically only two things happened in the final reduction:
empty buckets were filled, and pipeline aggs were reduced (since it
was the final reduction, this was safe).  Usage of the final reduction
is growing however.  Auto-date-histo might need to perform
many reductions on final-reduce to merge down buckets, CCS
may need to side-step the final reduction if sending to a
different cluster, etc

Having pipelines generate their output in the final reduce was
convenient, but is becoming increasingly difficult to manage
as the rest of the agg framework advances.

This commit decouples pipeline aggs from the final reduction by
introducing a new "top level" reduce, which should be called
at the beginning of the reduce cycle (e.g. from the SearchPhaseController).
This will only reduce pipeline aggs on the final reduce after
the non-pipeline agg tree has been fully reduced.

By separating pipeline reduction into their own set of methods,
aggregations are free to use the final reduction for whatever
purpose without worrying about generating pipeline results
which are non-reducible

Stop Allocating Buffers in CopyBytesSocketChannel (#49825) (#49832)
* Stop Allocating Buffers in CopyBytesSocketChannel (#49825)

The way things currently work, we read up to 1M from the channel
and then potentially force all of it into the `ByteBuf` passed
by Netty. Since that `ByteBuf` tends to by default be `64k` in size,
large reads will force the buffer to grow, completely circumventing
the logic of `allocHandle`.

This seems like it could break
`io.netty.channel.RecvByteBufAllocator.Handle#continueReading`
since that method for the fixed-size allocator does check
whether the last read was equal to the attempted read size.
So if we set `64k` because that's what the buffer size is,
then wirte `1M` to the buffer we will stop reading on the IO loop,
even though the channel may still have bytes that we can read right away.

More imporatantly though, this can lead to running OOM quite easily
under IO pressure as we are forcing the heap buffers passed to the read
to `reallocate`.

Extend systemd timeout during startup (#49784)
When we are notifying systemd that we are fully started up, it can be
that we do not notify systemd before its default timeout of sixty
seconds elapses (e.g., if we are upgrading on-disk metadata). In this
case, we need to notify systemd to extend this timeout so that we are
not abruptly terminated. We do this by repeatedly sending
EXTEND_TIMEOUT_USEC to extend the timeout by thirty seconds; we do this
every fifteen seconds. This will prevent systemd from abruptly
terminating us during a long startup. We cancel the scheduled execution
of this notification after we have successfully started up.

Make BlobStoreRepository Aware of ClusterState (#49639) (#49711)
* Make BlobStoreRepository Aware of ClusterState (#49639)

This is a preliminary to #49060.

It does not introduce any substantial behavior change to how the blob store repository
operates. What it does is to add all the infrastructure changes around passing the cluster service to the blob store, associated test changes and a best effort approach to tracking the latest repository generation on all nodes from cluster state updates. This brings a slight improvement to the consistency
by which non-master nodes (or master directly after a failover) will be able to determine the latest repository generation. It does not however do any tricky checks for the situation after a repository operation
(create, delete or cleanup) that could theoretically be used to get even greater accuracy to keep this change simple.
This change does not in any way alter the behavior of the blobstore repository other than adding a better "guess" for the value of the latest repo generation and is mainly intended to isolate the actual logical change to how the
repository operates in #49060

Refactor percolator's QueryAnalyzer to use QueryVisitors
Lucene now allows us to explore the structure of a query using QueryVisitors,
delegating the knowledge of how to recurse through and collect terms to the
query implementations themselves. The percolator currently has a home-grown
external version of this API to construct sets of matching terms that must be
present in a document in order for it to possibly match the query.

This commit removes the home-grown implementation in favour of one using
QueryVisitor. This has the added benefit of making interval queries available
for percolator pre-filtering. Due to a bug in multi-term intervals (LUCENE-9050)
it also includes a clone of some of the lucene intervals logic, that can be removed
once upstream has been fixed.

Introduce dedicated ingest processor exception (#48810)
Today we wrap exceptions that occur while executing an ingest processor
in an ElasticsearchException. Today, in ExceptionsHelper#unwrapCause we
only unwrap causes for exceptions that implement
ElasticsearchWrapperException, which the top-level
ElasticsearchException does not. Ultimately, this means that any
exception that occurs during processor execution does not have its cause
unwrapped, and so its status is blanket treated as a 500. This means
that while executing a bulk request with an ingest pipeline,
document-level failures that occur during a processor will cause the
status for that document to be treated as 500. Since that does not give
the client any indication that they made a mistake, it means some
clients will enter infinite retries, thinking that there is some
server-side problem that merely needs to clear. This commit addresses
this by introducing a dedicated ingest processor exception, so that its
causes can be unwrapped. While we could consider a broader change to
unwrap causes for more than just ElasticsearchWrapperExceptions, that is
a broad change with unclear implications. Since the problem of reporting
500s on client errors is a user-facing bug, we take the conservative
approach for now, and we can revisit the unwrapping in a future change.

Copy http headers to ThreadContext strictly (#45945) (#48675)
Previous behavior while copying HTTP headers to the ThreadContext,
would allow multiple HTTP headers with the same name, handling only
the first occurrence and disregarding the rest of the values. This
can be confusing when dealing with multiple Headers as it is not
obvious which value is read and which ones are silently dropped.

According to RFC-7230, a client must not send multiple header fields
with the same field name in a HTTP message, unless the entire field
value for this header is defined as a comma separated list or this
specific header is a well-known exception.

This commits changes the behavior in order to be more compliant to
the aforementioned RFC by requiring the classes that implement
ActionPlugin to declare if a header can be multi-valued or not when
registering this header to be copied over to the ThreadContext in
ActionPlugin#getRestHeaders.
If the header is allowed to be multivalued, then all such headers
are read from the HTTP request and their values get concatenated in
a comma-separated string.
If the header is not allowed to be multivalued, and the HTTP
request contains multiple such Headers with different values, the
request is rejected with a 400 status.
