The camel case name `nGram` should be removed in favour of `ngram` and

warnings for indices with versions 6.4.0 and higher and logs deprecation
warnings.
Since #30143, the Cluster State API should always returns the current
cluster_uuid in the response body, regardless of the metrics filters.
This is not exactly true as it is returned only if metadata metrics and
no specific indices are requested.
This commit fixes the behavior to always return the cluster_uuid and
add new test.
This test failed but the cause is not obvious. This commit adds more
debug logging traces so that if it reproduces we could gather more

Date histograms on non-fixed timezones such as `Europe/Paris` proved much slower
than histograms on fixed timezones in #28727. This change mitigates the issue by
using a fixed time zone instead when shard data doesn't cross a transition so
that all timestamps share the same fixed offset. This should be a common case
with daily indices.
NOTE: Rewriting the aggregation doesn't work since the timezone is then also
used on the coordinating node to create empty buckets, which might be out of the
range of data that exists on the shard.
NOTE: In order to be able to get a shard context in the tests, I reused code
from the base query test case by creating a new parent test case for both
queries and aggregations: `AbstractBuilderTestCase`.

This pipeline aggregation gives the user the ability to script functions that "move" across a window
of data, instead of single data points. It is the scripted version of MovingAvg pipeline agg.
Through custom script contexts, we expose a number of convenience methods:
- MovingFunctions.max()
- MovingFunctions.min()
- MovingFunctions.sum()
- MovingFunctions.unweightedAvg()
- MovingFunctions.linearWeightedAvg()
- MovingFunctions.ewma()
- MovingFunctions.holt()
- MovingFunctions.holtWinters()
- MovingFunctions.stdDev()
The user can also define any arbitrary logic via their own scripting, or combine with the above methods.
The TemplateUpgradeService is a system service that allows for plugins

this commit set an empty system context for the execution of the
template upgrades performed by this service.

When processing a top-level sibling pipeline, we destructively sublist
the path by assigning back onto the same variable. But if aggs are
specified such:
A. Multi-bucket agg in the first entry of our internal list
B. Regular agg as the immediate child of the multi-bucket in A
C. Regular agg with the same name as B at the top level, listed as the
second entry in our internal list
D. Finally, a pipeline agg with the path down to B
We'll get class cast exception. The first agg will sublist the path
from [A,B] to [B], and then when we loop around to check agg C,
the sublisted path [B] matches the name of C and it fails.
The fix is simple: we just need to store the sublist in a new object
so that the old path remains valid for the rest of the aggs in the loop

* Fixes IndiceOptionsTests to serialise correctly
Previous to this change `IndicesOptionsTests.testSerialisation()` would
select a complete random version for both the `StreamOutput` and the
`StreamInput`. This meant that the output could be selected as 7.0+
while the input was selected as <7.0 causing the stream to be written
in the new format and read in teh old format (or vica versa). This
change splits the two cases into different test methods ensuring that
the Streams are at least on compatibile versions even if they are on
different versions.

The order in which double values are added in java can give different results

In #28255 the implementation of the elasticsearch.keystore was changed

a value consisting of all 0 bytes.
This change restores the previous behaviour as closely as possible.
It is possible to retrieve the _keys_ from a closed keystore, but any

#30423 combined auto-expansion in the same cluster state update where nodes are removed. As
the auto-expansion step would run before deassociating the dead nodes from the routing table, the
auto-expansion would possibly remove replicas from live nodes instead of dead ones. This commit
reverses the order to ensure that when nodes leave the cluster that the auto-expand-replica
functionality only triggers after failing the shards on the removed nodes. This ensures that active
shards on other live nodes are not failed if the primary resided on a now dead node.
Instead, one of the replicas on the live nodes first gets promoted to primary, and the auto-
expansion (removing replicas) only triggers in a follow-up step (but still same cluster state update).

We currently have a separate endpoint for retrieving settings from all indices. We introduced such endpoint when removing comma-separated feature parsing for GetIndicesAction. The RestGetAllSettingsAction duplicates the code to print out the response that we already have in GetSettingsResponse (since it became a ToXContentObject), and uses the get index API internally instead of the get settings API, but the response is the same, hence we can fold get all settings and get settings in a single API, which is what this commit does.
This commit changes the default out-of-the-box configuration for the
number of shards from five to one. We think this will help address a
common problem of oversharding. For users with time-based indices that
need a different default, this can be managed with index templates. For
users with non-time-based indices that find they need to re-shard with
the split API in place they no longer need to resort only to
reindexing.
Since this has the impact of changing the default number of shards used
in REST tests, we want to ensure that we still have coverage for issues
that could arise from multiple shards. As such, we randomize (rarely)
the default number of shards in REST tests to two. This is managed via a
global index template. However, some tests check the templates that are
in the cluster state during the test. Since this template is randomly
there, we need a way for tests to skip adding the template used to set
the number of shards to two. For this we add the default_shards feature
skip. To avoid having to write our docs in a complicated way because
sometimes they might be behind one shard, and sometimes they might be
behind two shards we apply the default_shards feature skip to all docs
tests. That is, these tests will always run with the default number of
shards (one).
The second set of assertions was accidentally using the count's
moving average for the error delta in the value's moving average
assertion. This fixes the typo, and unmutes the test.

Previously `BulkProcessor` retry logic was based on the exception type of the failed response (`EsRejectedExecutionException`). This commit changes it to be based on the returned status code.

This change has no effect on the transport client.

`coordinating_only:false` deletes them.

When deleting or creating a snapshot for a given shard, elasticsearch
usually starts by listing all the existing snapshotted files in the repository.
Then it computes a diff and deletes the snapshotted files that are not
needed anymore. During this deletion, an exception is thrown if the file
to be deleted does not exist anymore.
This behavior is challenging with cloud based repository implementations
like S3 where a file that has been deleted can still appear in the bucket for
few seconds/minutes (because the deletion can take some time to be fully
replicated on S3). If the deleted file appears in the listing of files, then the
following deletion will fail with a NoSuchFileException and the snapshot
will be partially created/deleted.
This pull request makes the deletion of these files a bit less strict, ie not
failing if the file we want to delete does not exist anymore. It introduces a
new BlobContainer.deleteIgnoringIfNotExists() method that can be used
at some specific places where not failing when deleting a file is
considered harmless.

We were recently looking at bugs that can only occur if two different documents were indexed concurrently. For example, what happens if the local checkpoint advances above the sequence number of a document that's being indexed. That can only happen if another concurrent operation caused the checkpoint to advance. It has to be another document to allow concurrency as we acquire a per uid lock.While our investigation proved that the suspected bug doesn't exists, we still discovered our unit testing coverage is not good enough to cover this case.
This PR extend the test concurrent out of order replica processing to use two documents in its history.
The Get Repositories response object held a list of RepositoryMetaData
entries. This object does not have the from/toXContent methods that are
needed to expose this to the high level REST client. The
RepositoriesMetaData, however, does, and it also contains a list of
RepositoryMetaData objects within it. So rather than duplicate this
logic or move it (RepositoriesMetaData is a fragment object used by
cluster state), the object holding state in the Response was changed to
use the RepositoriesMetaData instead. This also cleans up the read/write
methods in the response, as they can now use the same read/write in
RepositoriesMetaData, which also were not present in the singular class.
Fix NPE when CumulativeSum agg encounters null/empty bucket
If the cusum agg encounters a null value, it's because the value is
missing (like the first value from a derivative agg), the path is
not valid, or the bucket in the path was empty.
Previously cusum would just explode on the null, but this changes it
so we only increment the sum if the value is non-null and finite.
This is safe because even if the cusum encounters all null or empty
buckets, the cumulative sum is still zero (like how the sum agg returns
zero even if all the docs were missing values)
I went ahead and tweaked AggregatorTestCase to allow testing pipelines,
so that I could delete the IT test and reimplement it as AggTests.

Suggester Options have a collate match field that is returned when the prune
option is set to true. These values should be merged together in the query
reduce phase, otherwise good suggestions that result in rare hits in shards with
results that do not arrive first may be incorrectly marked as not matching the
collate query.
At the end of recovery, we mark the recovering shard as "in sync" on the primary. From this point on
the primary will treat any replication failure on it as critical and will reach out to the master to fail the
shard. To do so, we wait for the local checkpoint of the recovered shard to be above the global
checkpoint (in order to maintain global checkpoint invariant).
If the master decides to cancel the allocation of the recovering shard while we wait, the method can
currently hang and fail to return. It will also ignore the interrupts that are triggered by the cancelled
recovery due to the primary closing.
Note that this is crucial as this method is called while holding a primary permit. Since the method
never comes back, the permit is never released. The unreleased permit will then block any primary
relocation *and* while the primary is trying to relocate all indexing will be blocked for 30m as it
waits to acquire the missing permit.
The code in `SourceRecoveryHandler` runs under a `CancellableThreads` instance in order to allow long running operations to be interrupted when the recovery is cancelled. Sadly if this happens at just the wrong moment while acquiring a permit from the primary, that primary can be leaked and never be freed.
Note that this is slightly better than it sounds - we only cancel recoveries on the source side if the primary shard itself is closed.

Today when an index is created from shrinking or splitting an existing
index, the target index inherits almost none of the source index
settings. This is surprising and a hassle for operators managing such
indices. Given this is the default behavior, we can not simply change
it. Instead, we start by introducing the ability to copy settings. This
flag can be set on the REST API or on the transport layer and it has the
behavior that it copies all settings from the source except non-copyable
settings (a property of a setting introduced in this
change). Additionally, settings on the request will always override.
This change is the first step in our adventure:
- this flag is added here in 7.0.0 and immediately deprecated
- this flag will be backported to 6.4.0 and remain deprecated
- then, we will remove the ability to set this flag to false in 7.0.0
- finally, in 8.0.0 we will remove this flag and the only behavior will
be for settings to be copied
Just like `ElasticsearchException`, the inner most
`XContentParseException` tends to contain the root cause of the
exception and show be show to the user in the `root_cause` field.
The effectively undoes most of the changes that #29373 made to the
`root_cause` for parsing exceptions. The `type` field still changes from
`parse_exception` to `x_content_parse_exception`, but this seems like a
fairly safe change.
`ElasticsearchWrapperException` *looks* tempting to implement this but
the behavior isn't quite right. `ElasticsearchWrapperExceptions` are
entirely unwrapped until the cause no longer
`implements ElasticsearchWrapperException` but `XContentParseException`
should be unwrapped until its cause is no longer an
`XContentParseException` but no further. In other words,
`ElasticsearchWrapperException` are unwrapped one step too far.

Starting with the refactoring in https://github.com/elastic/elasticsearch/pull/22778 (released in 5.3) we may fail to properly replicate operation when a mapping update on master fails. If a bulk
operations needs a mapping update half way, it will send a request to the master before continuing
to index the operations. If that request times out or isn't acked (i.e., even one node in the cluster
didn't process it within 30s), we end up throwing the exception and aborting the entire bulk. This is
a problem because all operations that were processed so far are not replicated any more to the
replicas. Although these operations were never "acked" to the user (we threw an error) it cause the
local checkpoint on the replicas to lag (on 6.x) and the primary and replica to diverge.
This PR does a couple of things:
1) Most importantly, treat *any* mapping update failure as a document level failure, meaning only
the relevant indexing operation will fail.
2) Removes the mapping update callbacks from `IndexShard.applyIndexOperationOnPrimary` and
similar methods for simpler execution. We don't use exceptions any more when a mapping
update was successful.
I think we need to do more work here (the fact that a single slow node can prevent those mappings
updates from being acked and thus fail operations is bad), but I want to keep this as small as I can
(it is already too big).
Currently, the only way to get the REST response for the `/_cluster/state`
call to return the `cluster_uuid` is to request the `metadata` metrics,
which is one of the most expensive response structures. However, external
monitoring agents will likely want the `cluster_uuid` to correlate the
response with other API responses whether or not they want cluster
metadata.
Today when a resize operation is performed, we copy the analysis,
similarity, and sort settings from the source index. It is possible for
the resize request to include additional index settings including
analysis, similarity, and sort settings. We reject sort settings when
validating the request. However, we silently ignore analysis and
similarity settings on the request that are already set on the source
index. Since it is possible to change the analysis and similarity
settings on an existing index, this should be considered a bug and the
sort of leniency that we abhor. This commit addresses this bug by
allowing the request analysis/similarity settings to override the
existing analysis/similarity settings on the target.
The `testDeleteSnapshotWithMissingIndexAndShardMetadata` test uses an
obsolete repository directory structure based on index names instead of
UUIDs. Because it swallows exceptions when deleting test files the test
never failed when the directory structure changed.
This commit fixes the test to use the right directory structure and file
names and to not swallow exceptions anymore.
The REST resize handlers for shrink/split operations are effectively the
same code with a minor difference. This commit collapse these handlers
into a single base class.
This is a code-tidying PR, a little side adventure while working on
another change. Previously only shrink request existed but when the
ability to split indices was added, shrink and split were done together
under a single request object: the resize request object. However, the
code inherited the legacy name in the naming of some variables. This
commit cleans this up.
Since #28049, only fully initialized shards are received write requests.
This enhancement allows us to handle all exceptions. In #28571, we
started strictly handling shard-not-available exceptions and tried to
keep the way we report replication errors to users by only reporting if
the error is not shard-not-available exceptions. However, since then we
unintentionally always log warn for all exception. This change restores
to the previous behavior which logs warn only if an exception is not a
shard-not-available exception.

The global ordinals terms aggregator has an option to remap global ordinals to
dense ordinal that match the request. This mode is automatically picked when the terms
aggregator is a child of another bucket aggregator or when it needs to defer buckets to an
aggregation that is used in the ordering of the terms.
Though when building the final buckets, this aggregator loops over all possible global ordinals
rather than using the hash map that was built to remap the ordinals.
For fields with high cardinality this is highly inefficient and can lead to slow responses even
when the number of terms that match the query is low.
This change fixes this performance issue by using the hash table of matching ordinals to perform
the pruning of the final buckets for the terms and significant_terms aggregation.
I ran a simple benchmark with 1M documents containing 0 to 10 keywords randomly selected among 1M unique terms.
This field is used to perform a multi-level terms aggregation using rally to collect the response times.

"terms":{
"field":"keyword"
},
"aggregations":{
"2":{
"terms":{
"field":"keyword"
}
}
}
}

This commit fixes two issues with the byte size value equals/hash code
test.
The first problem is due to a test failure when the original instance is
zero bytes and we pick the mutation branch where we preserve the size
but change the unit. The mutation should result in a different byte size
value but changing the unit on zero bytes still leaves us with zero
bytes.
During the course of fixing this test I discovered another problem. When
we need to randomize size, we could randomly select a size that would
lead to an overflow of Long.MAX_VALUE.
This commit fixes both of these issues.

distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
Adds a check in BlobstoreRepository.snapshot(...) that prevents duplicate snapshot names and fails
the snapshot before writing out the new index file. This ensures that you cannot end up in this

The suggest stats were folded into the search stats as part of the
indices stats API in 5.0.0. However, the suggest metric remained as a
synonym for the search metric for BWC reasons. This commit deprecates
usage of the suggest metric on the indices stats API.
Similarly, due to the changes to fold the suggest stats into the search
stats, requesting the suggest index metric on the indices metric on the
nodes stats API has produced an empty object as the response since
5.0.0. This commit deprecates this index metric on the indices metric on
the nodes stats API.
This commit implements the ability to remove values from a Cache using
the values iterator. This brings the values iterator in line with the
keys iterator and adds support for removing items in the cache that are
not easily found by the key used for the cache.
Previously we did not put an indexing to a version map if that map does
not require safe access but removed the existing delete tombstone only
if assertion enabled. In #29585, we removed the side-effect caused by
assertion then this test started failing. This failure can be explained
as follows:
- Step 1: Index a doc then delete that doc
- Step 2: The version map can switch to unsafe mode because of
concurrent refreshes (implicitly called by flushes)
- Step 3: Index a document - the version map won't add this version
value and won't prune the tombstone (previously it did)
- Step 4: Delete a document - this will return NOT_FOUND instead of
DELETED because of the stale delete tombstone
This failure is actually fixed by #29619 in which we never leave stale
delete tombstones
Closes#29626
Today the VersionMap does not clean up a stale delete tombstone if it
does not require safe access. However, in a very rare situation due to
concurrent refreshes, the safe-access flag may be flipped over then an
engine accidentally consult that stale delete tombstone.
This commit ensures to never leave stale delete tombstones in a version
map by always pruning delete tombstones when putting a new index entry
regardless of the value of the safe-access flag.
This commit remove serializing of common stats flags via its enum
ordinal and uses an explicit index defined on the enum. This is to
enable us to remove an unused flag (Suggest) without ruining the
ordering and thus breaking serialization.
We removed catched throwable from the code base and left behind was a
comment about catching InternalError in MemoryManagementMXBean. We are
not going to catch InternalError here as we expect that to be
fatal. This commit removes that stale comment.
The name of the bulk thread pool was renamed to "write" with "bulk" as a
fallback name. This change was made in 6.x for BWC reasons yet in 7.0.0
we are removing this fallback. This commit removes this fallback for the
write thread pool.
Today when a version map does not require safe access, we will skip that
document. However, if the assertion is enabled, we remove the delete
tombstone of that document if existed. This side-effect may accidentally
hide bugs in which stale delete tombstone can be accessed.
This change ensures putAssertionMap not modify the tombstone maps.
The camel case name `htmlStip` should be removed in favour of `html_strip`, but
we need to deprecate it first. This change adds deprecation warnings for indices
with version starting with 6.3.0 and logs deprecation warnings in this cases.
This commit renames the bulk thread pool to the write thread pool. This
is to better reflect the fact that the underlying thread pool is used to
execute any document write request (single-document index/delete/update
requests, and bulk requests).
With this change, we add support for fallback settings
thread_pool.bulk.* which will be supported until 7.0.0.
We also add a system property so that the display name of the thread
pool remains as "bulk" if needed to avoid breaking users.
Now that single-document indexing requests are executed on the bulk
thread pool the index thread pool is no longer needed. This commit
removes this thread pool from Elasticsearch.
Binary doc values are retrieved during the DocValueFetchSubPhase through an instance of ScriptDocValues.
Since 6.0 ScriptDocValues instances are not allowed to reuse the object that they return (https://github.com/elastic/elasticsearch/issues/26775) but BinaryScriptDocValues doesn't follow this restriction and reuses instances of BytesRefBuilder among different documents.
This results in `field` values assigned to the wrong document in the response.
This commit fixes this issue by recreating the BytesRef for each value that needs to be returned.
Fixes#29565
When comparing doubles, fixed epsilons can fail because the absolute
difference in values may be quite large, even though the relative
difference is tiny (e.g. with two very large numbers).
Instead, we can scale epsilon by the absolute value of the expected
value. This means we are looking for a diff that is epsilon-percent
away from the value, rather than just epsilon.
This is basically checking the relative error using junit's assertEqual.
Closes#29456, unmutes the test
As part of adding support for new API to the high-level REST client,
we added support for the `flat_settings` parameter to some of our
request classes. We added documentation that such flag is only ever
read by the high-level REST client, but the truth is that it doesn't
do anything given that settings are always parsed back into a `Settings`
object, no matter whether they are returned in a flat format or not.
It was a mistake to add support for this flag in the context of the
high-level REST client, hence this commit removes it.
This refactors MapperService so that it wraps a single `DocumentMapper` rather
than a `Map<String, DocumentMapper>`. We will need follow-ups since I haven't
fixed most APIs that still expose collections of types of mappers, but this is
a start...
Today the translog of an engine is exposed and can be accessed directly.
While this exposure offers much flexibility, it also causes these troubles:
- Inconsistent behavior between translog method and engine method.
For example, rolling a translog generation via an engine also trims
unreferenced files, but translog's method does not.
- An engine does not get notified when critical errors happen in translog
as the access is direct.
This change isolates translog of an engine and enforces all accesses to
translog via the engine.
The index thread pool is no longer needed as its primary use-case for
single-document indexing requests has been relieved now that
single-document indexing requests are converted to bulk indexing
requests (with a single document payload).
We want to remove the index thread pool as it is no longer needed since
single-document indexing requests are executed as bulk requests
now. Analyze requests are also executed on the index thread pool though
and they need a thread pool to execute on. The bulk thread does not seem
like the right thread pool, let us keep that thread pool conceptually
for bulk requests and free for bulk requests. None of the existing
thread pools make sense for analyze requests either. The generic thread
pool would be a terrible choice since it has an unbounded queue and that
is a bad idea for user-facing APIs. This commit introduces a small by
default (size=1, queue_size=16) thread pool for analyze requests.
This commit add the `include_type_name` option to the `index`, `update`,
`delete`, `get`, `bulk` and `search` APIs. When set to `false`, the response
will omit the `_type` in the response. This option doesn't work if the endpoint
contains a type. For instance, the following call would succeed:
```
GET index/_doc/1?include_type_name=false
```
But the following one would fail:
```
GET index/some_type/1?include_type_name=false
```

With the move long ago to execute all single-document indexing requests
as bulk indexing request, the method
PipelineExecutionService#executeIndexRequest is unused and will never be
used in production code. This commit removes this method and cuts over
all tests to use PipelineExecutionService#executeBulkRequest.
CRUD: Parsing changes for UpdateRequest (#29293)
Use `ObjectParser` to parse `UpdateRequest` so we reject unknown fields
and drop support for the `_fields` parameter because it was deprecated
in 5.x.
The default percentiles values and the default highlighter per- and
post-tags are currently publicly accessible and can be altered any time.
This change prevents this by restricting field access.
Today when reading an operation from the current generation fails
tragically we attempt to close the translog. However, by invoking close
before releasing the read lock we end up in self-deadlock because
closing tries to acquire the write lock and the read lock can not be
upgraded to a write lock. To avoid this, we move the close invocation
outside of the try-with-resources that acquired the read lock. As an
extra guard against this, we document the problem and add an assertion
that we are not trying to invoke close while holding the read lock.
This change adds a client that is connected to a remote cluster.
This allows plugins and internal structures to invoke actions on
remote clusters just like a if it's a local cluster. The remote
cluster must be configured via the cross cluster search infrastructure.
This adds 2 testcases that test if a shard goes idle
pending (uncommitted) segments are committed and unreferenced
files will be freed.

"http.max_warning_header_size" to control the maximum total size of
warning headers in client HTTP responses.
Defaults to unbounded.
With every warning header that exceeds these limits,
a message will be logged in the main ES log,
and any more warning headers for this response will be
ignored.
Unlike the `indices.create`, `indices.get_mapping` and `indices.put_mapping`
APIs, the index APIs do not need the `include_type_name` option, they can work
work with and without types withouth knowing whether types are being used.
Internally, `_doc` is used as a type if no type is provided, like for the
`indices.put_mapping` API.
This change adds the current primary term to the header of the current
translog file. Having a term in a translog header is a prerequisite step
that allows us to trim translog operations given the max valid seq# for
that term.
This commit also updates tests to conform the primary term invariant
which guarantees that all translog operations in a translog file have
its terms at most the term stored in the translog header.

The skeleton of ElasticsearchMergePolicy is quite similar to
MergePolicyWrapper. This commit therefore makes ElasticsearchMergePolicy
inherited from MergePolicyWrapper instead of MergePolicy.
Currently, a flush stats contains only the total flush which is the sum
of manual flush (via API) and periodic flush (async triggered when the
uncommitted translog size is exceeded the flush threshold). Sometimes,
it's useful to know these two numbers independently. This commit tracks
and returns a periodic flush count in a flush stats.
This adds an `include_type_name` option to the `indices.create`,
`indices.get_mapping` and `indices.put_mapping` APIs, which defaults to `true`.
When set to `false`, then mappings will be returned directly in the body of
the `indices.get_mapping` API, without keying them by the type name, the
`indices.create` will expect mappings directly under the `mappings` key, and
the `indices.put_mapping` will use `_doc` as a type name and fail if a `type`
is provided explicitly.

Today we expose a mutable list of documents in ParseContext via
ParseContext#docs(). This, on the one hand places knowledge how
to access nested documnts in multiple places and on the other
allows for potential illegal access to nested only docs after
the docs are reversed. This change restricts the access and
streamlines nested / non-root doc access.
This change validates that the `_search` request does not have trailing
tokens after the main object and fails the request with a parsing exception otherwise.
Closes#28995
Some features have been deprecated since `6.0` like the `_parent` field or the
ability to have multiple types per index. This allows to remove quite some
code, which in-turn will hopefully make it easier to proceed with the removal
of types.
Today when a user runs a CLI tool with standard input closed and no tty
attached, the result from reading is null and this usually leads to a
null pointer exception when we try to parse this input. This arises for
example when the user runs the plugin installer through a Docker
container without leaving standard input open and attaching a tty
(docker exec <container ID> bin/elasticsearch-plugin install). When we
try to read that the user accepts the plugin requiring additional
security permissions we will get back null. This commit addresses this
for all cases by throwing an illegal state exception. The solution for
the user is leave standard input open and attach a tty (or, for some
tools, use batch mode).
#29409 removed the nearlyEquals() double comparison snippet, which
makes these tests very flaky because they can generate very large or
very small doubles which don't work well with absolute error comparison.
We need to either refactor these tests to guarantee they stay in a small
range (which could be difficult due to holt/holt-winters) or re-implement
the more robust double comparison.
Tracking issue: #29456
This commit simplifies the exception handling in
TranslogWriter#closeWithTragicEvent. When invoking this method, the
inner close method could throw an exception which we always catch and
suppress into the exception that led us to tragically close. This commit
moves that repeated logic into closeWithTragicException and now callers
simply need to catch, invoke closeWithTragicException, and rethrow.
* Remove copy-pasted code
We had two instances of copy-pasted code with a bad license from
another website. The code was doing something rather simple, and
that functionality already exists within junit. This PR simply leverages
the junit functionality.
`BaseRandomBinaryDocValuesRangeQueryTestCase.testRandomBig` should only run with
nightly tests. It doesn't make sense to make it part of every test run.
`UUIDTests` had a slow test for compression, which I made a bit faster by
decreasing the number of indexed docs.
This commit fixes the formatting of the values in the composite
aggregation response. `date` fields should return timestamp as longs
when used in a `terms` source and `ip` fields should always be formatted as strings.
This commit also fixes the parsing of the `after` key for these field types.
Finally, this commit disables the index optimization for the `ip` field and any source that provides a `missing` value.
This commit simplifies the invocations to
Translog#closeOnTragicEvent. This method already catches all possible
exceptions and suppresses the non-AlreadyClosedExceptions into the
exception that triggered the invocation. Therefore, there is no need for
callers to do this same logic (which would never execute).
* Move Streams.copy into elasticsearch-core and make a multi-release jar
This moves the method `Streams.copy(InputStream in, OutputStream out)` into the

Today we close the translog write tragically if we experience any I/O
exception on a write. These tragic closes lead to use closing the
translog and failing the engine. Yet, there is one case that is missed
which is when we touch the write channel during a read (checking if
reading from the writer would put us past what has been flushed). This
commit addresses this by closing the writer tragically if we encounter
an I/O exception on the write channel while reading. This becomes
interesting when we consider that this method is invoked from the engine
through the translog as part of getting a document from the
translog. This means we have to consider closing the translog here as
well which will cascade up into us finally failing the engine.
Note that there is no semantic change to, for example, primary/replica
resync and recovery. These actions will take a snapshot of the translog
which syncs the translog to disk. If an I/O exception occurs during the
sync we already close the writer tragically and once we have synced we
do not ever read past the position that was synced while taking the
snapshot.

Since #26542 the NodeVersionAllocationDecider tries to explain its NO decisions
as follows:
... may not support codecs or postings formats for a newer Lucene version
However, this message often appears during a rolling upgrade, and experience
has shown that it seems to cause more confusion and worry than it needs to.
This change fixes that by removing the explanation again, reducing the message
to a statement of fact about the respective nodes' versions.
Additionally, the same wording was used for version incompatibilities when
allocating a primary (vs its previous location) and a replica (vs its primary).
This change separates these two cases so they can have separate, clearer
wording.

`action.master.force_local` was only ever used internally and never documented. It was one of those settings that were
automatically added to a tribe node, to make sure that cluster state read operations would work locally rather than failing when trying to forward the request to the master (as the tribe node never had a master).
Given that we recently removed the tribe node, we can also remove this setting.
Today when you input a byte size setting that is out of bounds for the
setting, you get an error message that indicates the maximum value of
the setting. The problem is that because we use ByteSize#toString, we
end up with a representation of the value that does not really tell you
what the bound is. For example, if the bound is 2^31 - 1 bytes, the
output would be 1.9gb which does not really tell you want the limit as
there are many byte size values that we format to the same 1.9gb with
ByteSize#toString. We have a method ByteSize#getStringRep that uses the
input units to the value as the output units for the string
representation, so we end up with no loss if we use this to report the
bound. This commit does this.
Before doing any kind of validation on a new mapping, we should first do the multi-type validation in
order to provide better error messages. For #29313, this means that the exception message will be
Rejecting mapping update to [range_index_new] as the final mapping would have more than 1 type:
[_doc, mytype]
instead of
[expected_attendees] is defined as an object in mapping [mytype] but this name is already used for
a field in other types
Today we report thread pool info using a common object. This means that
we use a shared set of terminology that is not consistent with the
terminology used to the configure thread pools. This holds in particular
for the minimum and maximum number of threads in the thread pool where
we use the following terminology:
thread pool info | fixed | scaling
min core size
max max size
A previous change addressed this for the nodes info API. This commit
changes the display of thread pool info in the cat thread pool API too
to be dependent on the type of the thread pool so that we can align the
terminology in the output of thread pool info with the terminology used
to configure a thread pool.
Today we reply on `IndexWriter#hasDeletions` to check if an index
contains "update" operations. However, this check considers both deletes

This moves the `Nullable` annotation into the elasticsearch-core project, so it
may be used without relying entirely on the server jar. This will allow us to
decouple more pieces to make them smaller.
In addition, there were two different `Nullable` annotations, these have all
been moved to the ES version rather than the inject version.
We have seen exceptions bubble up to the uncaught exception handler. Checking the blocks can
lead for example to IndexNotFoundException when the indices are resolved. In order to make
TransportMasterNodeAction more resilient against such expected exceptions, this code change
wraps the execution of doStart() into a try catch and informs the listener in case of failures.
DiskThresholdDecider currently assumes that the source index of a resize operation (e.g. shrink)
is available, and throws an IndexNotFoundException otherwise, thereby breaking any kind of shard
allocation. This can be quite harmful if the source index is deleted during a shrink, or if the source
index is unavailable during state recovery.
While this behavior has been partly fixed in 6.1 and above (due to #26931), it relies on the order in
which AllocationDeciders are executed (i.e. that ResizeAllocationDecider returns NO, ensuring that
DiskThresholdDecider does not run, something that for example does not hold for the allocation
explain API).
This change adds a more complete fix, and also solves the situation for 5.6.
* Pass script level params into scripted metric aggs (#28819)

I am not sure why we have this leniency for HTTP max content length, it
has been there since the beginning
(5ac51ee93f) with no explanation of its
source. That said, our philosophy today is different than the philosophy

of settings and today we aim for predictability for both users and
us. This commit removes leniency in the parsing of
http.max_content_length.
* Begin moving XContent to a separate lib/artifact
This commit moves a large portion of the XContent code from the `server` project
to the `libs/xcontent` project. For the pieces that have been moved, some
helpers have been duplicated to allow them to be decoupled from ES helper
classes. In addition, `Booleans` and `CheckedFunction` have been moved to the
`elasticsearch-core` project.
This decoupling is a move so that we can eventually make things like the
high-level REST client not rely on the entire ES jar, only the parts it needs.
There are some pieces that are still not decoupled, in particular some of the
XContent tests still remain in the server project, this is because they test a
large portion of the pluggable xcontent pieces through
`XContentElasticsearchException`. They may be decoupled in future work.
Additionally, there may be more piecese that we want to move to the xcontent lib
in the future that are not part of this PR, this is a starting point.

Removes a set of assertions in the test framework that verified that
Streamable objects could be serialized and deserialized across different

This commit also removes a transport interceptor that was used in
ESIntegTestCase tests to make these assertions about objects coming in

The parsing code for script query currently silently skips by any tokens
it does not know about within its parsing loop. The only token it does

the others. This commit adds validation that arrays are not seen while

Today we have a few problems with how we handle bad requests:
- handling requests with bad encoding
- handling requests with invalid value for filter_path/pretty/human
- handling requests with a garbage Content-Type header
There are two problems:
- in every case, we give an empty response to the client
- in most cases, we leak the byte buffer backing the request!
These problems are caused by a broader problem: poor handling preparing
the request for handling, or the channel to write to when the response
is ready. This commit addresses these issues by taking a unified
approach to all of them that ensures that:
- we respond to the client with the exception that blew us up
- we do not leak the byte buffer backing the request
We historically removed reading from the transaction log to get consistent
results from _GET calls. There was also the motivation that the read-modify-update
principle we apply should not be hidden from the user. We still agree on the fact
that we should not hide these aspects but the impact on updates is quite significant
especially if the same documents is updated before it's written to disk and made serachable.
This change adds back the ability to read from the transaction log but only for update calls.
Calls to the _GET API will always do a refresh if necessary to return consistent results ie.
if stored fields or DocValues Fields are requested.
Closes#26802
When the `BulkProcessor` is used with the high-level REST client, a scheduler is internally created that allows to schedule tasks. Such scheduler is not exposed to users and needs to be closed once the `BulkProcessor` is closed. There are two ways to close the `BulkProcessor` though, one is the ordinary `close` method and the other one is `awaitClose`. The former closes the scheduler while the latter doesn't, leaving threads lingering.
DocumentParser: The checks for Text and Keyword were masked by the
earlier check for String, which they are child classes of. As String

Restoring a snapshot, or getting the status of finished
snapshots, currently always load the global state metadata

method into two distincts methods: getGlobalMetadata()
and getIndexMetadata() that are now called only when needed.
