When using a bulk processor, the thread context was not preserved for the flush runnable which is
executed in another thread in the thread pool. This change wraps the flush runnable in a context
preserving runnable so that the headers and transients from the creation time of the bulk processor
are available during the execution of the flush.
Closes#26596
The `fielddata` field and the use of the `_name` field in the short syntax of the range
query have been deprecated in 5.0 and can be removed.
The same goes for the deprecated `score_mode` field in HasParentQueryBuilder,
the deprecated `like_text`, `ids` and `docs` parameter in the `more_like_this` query,
the deprecated query name in the short version of the `regexp` query, and several
deprecated alternative field names in other query builders.
The `type` field has been deprecated in 5.0 and can be removed. It has been
replaced by using the MatchPhraseQueryBuilder or the
MatchPhrasePrefixQueryBuilder. The `slop` field has also been deprecated and can
be removed, the phrase and phrase prefix query builders still provide this
parameter.
- Removes mutual dependency between GatewayMetaState and TransportNodesListGatewayMetaState
- Deguices MetaDataIndexUpgradeService
- Deguices GatewayMetaState
- Makes Gateway the master-level component that is only responsible for coordinating the state recovery
Request class is currently package protected, making it difficult for
the users to extend the RestHighLevelClient and to use its protected
methods to execute requests. This commit makes the Request class public
and changes few methods of RestHighLevelClient to be protected.
The nested aggregator now buffers all bucket ords per parent document and
emits all bucket ords for a parent document's nested document once. This way
the nested documents document DocIdSetIterator gets used once per bucket
instead of wrapping the nested aggregator inside a multi bucket aggregator,
which was the current solution upto now. This allows sorting by buckets
under a nested bucket.
Closes#16838
When adding file based discovery, we added a fallback when the discovery
type was set to zen (the default, so everyone got this warning). This
commit removes the fallback for 6.0. Setting file discovery should now
happen explicitly through the hosts_provider setting.
closes#26661
This assertion is wrong because the global checkpoint on a promoted
primary can be lagging the replicas until it catches up after through
resyncs, ongoing indexing operations and removing the old primary from
the in-sync set.
TemplateUpgradeService might get stuck in repeatedly upgrading templates after upgrade to 5.6.0. This is caused by shuffling mappings definition in the template during template serialization. This commit makes the template serialization consistent.
Closes#26673
Restoring a shard from snapshot throws the primary back in time violating assumptions and bringing the validity of global checkpoints in question. To avoid problems, we should make sure that a shard that was restored will never be the source of an ops based recovery to a shard that existed before the restore. To this end we have introduced the notion of `histroy_uuid` in #26577 and required that both source and target will have the same history to allow ops based recoveries. This PR make sure that a shard gets a new uuid after restore.
As suggested by @ywelsch , I derived the creation of a `history_uuid` from the `RecoverySource` of the shard. Store recovery will only generate a uuid if it doesn't already exist (we can make this stricter when we don't need to deal with 5.x indices). Peer recovery follows the same logic (note that this is different than the approach in #26557, I went this way as it means that shards always have a history uuid after being recovered on a 6.x node and will also mean that a rolling restart is enough for old indices to step over to the new seq no model). Local shards and snapshot force the generation of a new translog uuid.

This commit moves the pre-6.0 node checkpoint constant from
SequenceNumbersService to SequenceNumbers so it can chill with the other
sequence number-related constants.

Request bodys that only consists of a String value can lead to endless loops in the
parser of several rest requests like e.g. `_count`. Up to 5.2 this seems to have been caught
in the logic guessing the content type of the request, but since then it causes the node to
block. This change introduces checks for receiving a valid xContent object before starting the
parsing in RestActions#parseTopLevelQueryBuilder().
Closes#26083
Adds several small whitelist data structures and a new Whitelist class to separate the idea of loading a whitelist from the actual Painless Definition class. This is the first step of many in allowing users to define custom whitelists per context. Also supports the idea of loading multiple whitelists from different sources for a single context.
* Add a version constant for 5.6.2 so that the 5.6.1 constant
represents the 5.6.1 release and the 5.6.2 constant represents
the unreleased 5.6 branch.
Today we can't validate the array length in `InputStreamStreamInput` since
we can't rely on `InputStream.available` yet in some situations we know
the size of the stream and can apply additional validation.
After recovery completes from a primary, we now update the local
knowledge on the primary of the global checkpoint on the recovery
target. However if this occurs concurrently with a relocation, an
assertion could trip that we are no longer in primary mode. As this
local knowledge should only be tracked when we are in primary mode,
updating this local knowledge should be done under a permit. This commit
causes that to be the case.
Relates #26666
When checking that the global checkpoint on the primary is consistent
with the local checkpoints of the in-sync shards, we have to filter
pre-6.0 nodes from the check or the invariant will trivially trip. This
commit filters these nodes out when checking this invariant.
Relates #26666
This commit adds a skip for the bad request REST test on pre-6.0
nodes. Previously, a request for /_(.*) where $1 is not an existing
endpoint would return a 404. This is because the request would be
treated as a get index request for an index named _$1. However, an index
can never start with "_" so logic was added to detect this and return a
400 instead as this should be treated as a bad request. During the
mixed-cluster BWC tests, a node running pre-6.0 code will still return a
404 though. Therefore, this test needs to skipped in such a
mixed-cluster scenario.
This commit reenables the BWC tests after they were disabled for
backporting the change to track global checkpoints of shard copies on
the primary.
Relates #26666
This commit adds local tracking of the global checkpoints on all shard
copies when a global checkpoint tracker is operating in primary
mode. With this, we relay the global checkpoint on a shard copy back to
the primary shard during replication operations. This serves as another
step towards adding a background sync of the global checkpoint to the
shard copies.

In this test, 260b is replaced by the regexp \d+b
but the test sometimes produces results like 1.1kb
so this commit adapts the regexp to match values
with decimals
The discovery-file plugin was not config path aware, so it always picked
up the default config path (from Elasticsearch home) rather than a
custom config path. This commit fixes the discovery-file plugin to
respect a custom config path.

This commit adds validation to the resolving of indexes in the wildcard
expression resolver. It no longer throws a 404 Not Found when resolving
invalid indices. It throws a 400 instead, as it is an invalid
index. This was the behavior of 5.x.
Initialize the default stop-tags in `KuromojiPartOfSpeechFilterFactory` if the
`stoptags` are not given in the config. Also adding a test which checks that
part-of-speech tokens are removed when using the kuromoji_part_of_speech
filter.
This avoids messages with malformed URLs, like
"org.elasticsearch.client.ResponseException: PUT
http://127.0.0.1:9502customer: HTTP/1.1 400 Bad Request".
