Since Elasticsearch 6.1.0 environment variable substitutions in lists do not work.
Environment variables in a list setting were not resolved, because settings with a list type were skipped during variables resolution.
This commit fixes by processing list settings as well.
Closes#27926
This commit adds the ability to package multiple plugins in a single zip.
The zip file for a meta plugin must contains the following structure:
|____elasticsearch/
| |____ <plugin1> <-- The plugin files for plugin1 (the content of the elastisearch directory)
| |____ <plugin2> <-- The plugin files for plugin2
| |____ meta-plugin-descriptor.properties <-- example contents below
The meta plugin properties descriptor is mandatory and must contain the following properties:
description: simple summary of the meta plugin.
name: the meta plugin name
The installation process installs each plugin in a sub-folder inside the meta plugin directory.
The example above would create the following structure in the plugins directory:
|_____ plugins
| |____ <name_of_the_meta_plugin>
| | |____ meta-plugin-descriptor.properties
| | |____ <plugin1>
| | |____ <plugin2>
If the sub plugins contain a config or a bin directory, they are copied in a sub folder inside the meta plugin config/bin directory.
|_____ config
| |____ <name_of_the_meta_plugin>
| | |____ <plugin1>
| | |____ <plugin2>
|_____ bin
| |____ <name_of_the_meta_plugin>
| | |____ <plugin1>
| | |____ <plugin2>
The sub-plugins are loaded at startup like normal plugins with the same restrictions; they have a separate class loader and a sub-plugin
cannot have the same name than another plugin (or a sub-plugin inside another meta plugin).
It is also not possible to remove a sub-plugin inside a meta plugin, only full removal of the meta plugin is allowed.
Closes#27316
This commit changes IndexShardSnapshotStatus so that the Stage is updated
coherently with any required information. It also provides a asCopy()
method that returns the status of a IndexShardSnapshotStatus at a given
point in time, ensuring that all information are coherent.
Closes#26480
If a newly created index from a rollover request matches with an index
template whose aliases contains the rollover request alias, the alias
will point to multiple indices. This will cause indexing requests to be
rejected. To avoid such situation, we make sure that there is no
duplicated alias before creating a new index; otherwise abort and report
an error to the caller.
Closes#26976
This commit removes the finalization of a snapshot by the snapshot deletion request. This way, the deletion marks the snapshot as ABORTED in cluster state and waits for the snapshot completion. It is the responsability of the snapshot execution to detect the abortion and terminates itself correctly. This
avoids concurrent snapshot finalizations and also ordinates the operations: the deletion
aborts the snapshot and waits for the snapshot completion, the creation detects the abortion
and stops by itself and finalizes the snapshot, then the deletion resumes and continues
the deletion process.
Several responses include the shards_acknowledged flag (indicating whether the
requisite number of shard copies started before the completion of the operation)
and there are two different getters used : isShardsAcknowledged() and isShardsAcked().
This PR deprecates the isShardsAcked() in favour of isShardsAcknowledged() in
CreateIndexResponse, RolloverResponse and CreateIndexClusterStateUpdateResponse.
Closes#27784
Previously this would default to the version of the remote Node.
However, if the remote cluster was mixed-version (e.g. it was part way through a
rolling upgrade), then the TransportService may have negotiated a connection
version that is not identical to connected Node's version.
This mismatch would cause the Stream and the (Remote)Connection to report
different version numbers, which could cause data to be sent over the wire
using an incorrect serialization version.
This is related to #27260. This commit moves the NioTransport from
:test:framework to a new nio-transport plugin. Additionally, supporting
tcp decoding classes are moved to this plugin. Generic byte reading and
writing contexts are moved to the nio library.
Additionally, this commit adds a basic MockNioTransport to
:test:framework that is a TcpTransport implementation for testing that
is driven by nio.
When calling the node stats action via the Java API it was not able to return
information about warmers and translog even though that is available through
the REST API. This change adds methods to make the responses more
consistent.
* Fix global aggregation that requires breadth first and scores
This change fixes the deferring collector when it is executed in a global context
with a sub collector thats requires to access scores (e.g. top_hits aggregation).
The deferring collector replays the best buckets for each document and re-executes the original query
if scores are needed. When executed in a global context, the query to replay is a simple match_all
query and not the original query.

Java 9 added some enhancements to the internationalization support that

Lucene does not allow adding Lucene 6 files to a Lucene 7 index. This commit ensures that we carry over the Lucene version to the newly created Lucene index.
Closes#28061
Allows TransportResponse objects not to implement Streamable anymore. As an example, I've adapted the response handler for ShardActiveResponse, allowing the fields in that class to become final.
This commit adds the infrastructure to plugin building and loading to
allow one plugin to extend another. That is, one plugin may extend
another by the "parent" plugin allowing itself to be extended through
java SPI. When all plugins extending a plugin are finished loading, the
"parent" plugin has a callback (through the ExtensiblePlugin interface)
allowing it to reload SPI.
This commit also adds an example plugin which uses as-yet implemented
extensibility (adding to the painless whitelist).
* Only bind loopback addresses when binding to local
Today when binding to local (the default) we bind to any address that is
a loopback address, or any address on an interface that declares itself
as a loopback interface. Yet, not all addresses on loopback interfaces
are loopback addresses. This arises on macOS where there is a link-local
address assigned to the loopback interface (fe80::1%lo0) and in Docker
services where virtual IPs of the service are assigned to the loopback
interface (docker/libnetwork#1877). These situations cause problems:
- because we do not handle the scope ID of a link-local address, we end
up bound to an address for which publishing of that address does not
allow that address to be reached (since we drop the scope)
- the virtual IPs in the Docker situation are not loopback addresses,
they are not link-local addresses, so we end up bound to interfaces
that cause the bootstrap checks to be enforced even though the
instance is only bound to local
We address this by only binding to actual loopback addresses, and skip
binding to any address on a loopback interface that is not a loopback
address. This lets us simplify some code where in the bootstrap checks
we were skipping link-local addresses, and in writing the ports file
where we had to skip link-local addresses because again the formatting
of them does not allow them to be connected to by another node (to be
clear, they could be connected to via the scope-qualified address, but
that information is not written out).

- Introduce index level settings to control the maximum number of terms
that can be used in a Terms Query
- Throw an error if a request exceeds this max number
Closes#18829
This change fixes a bug when a keyword term in the `after` key is not present in the shard.
In this case the global ord of the document values are compared with the insertion point of the
`after` keyword and values that are equal to the insertion point should be considered "after" the top value.
In PR #27965, we set the global checkpoint from the translog in a store
recovery. However, we set after an engine is opened. This causes the
global checkpoint assertion in TranslogWriter violated as if we are
forced to close the engine before we set the global checkpoint. A
closing engine will close translog which in turn read the current global
checkpoint; however it is still unassigned and smaller than the initial
global checkpoint from translog.
Closes#27970
Today we always recover a primary from the last commit point. However
with a new deletion policy, we keep multiple commit points in the
existing store, thus we have chance to find a good starting commit
point. With a good starting commit point, we may be able to throw away
stale operations. This PR rollbacks a primary to a starting commit then
recovering from translog.
Relates #10708
Non-Peer recoveries should restore the global checkpoint rather than wait for the activation of the primary. This brings us a step closer to a universe where a recovered shard always has a valid global checkpoint. Concretely:
1) Recovery from store can read the checkpoint from the translog
2) Recovery from local shards and snapshots can set the global checkpoint to the local checkpoint as this is the only copy of the shard.
3) Recovery of an empty shard can set it to `NO_OPS_PERFORMED`
Peer recoveries will follow but require more work and thus will have their own PR.
I also used the moment to clean up `IndexShard`'s api around starting the engine and doing recovery from the translog. The current naming are a relic of the past and don't align with the current naming schemes in the engine.
This assertion does not hold if a shard is recovered from an empty store
but failed then retries. Moreover, if the openMode is CREATE_INDEX_*, we
pass CREATE mode to the IndexWriterConfig to create a new index and
overwrite the existing one.
Closes#27960
When a new snapshot is created it is added to the cluster state as a
snapshot-in-progress in INIT state, and the initialization is kicked
off in a new runnable task by SnapshotService.beginSnapshot(). The
initialization writes multiple files before updating the cluster state
to change the snapshot-in-progress to STARTED state. This leaves a
short window in which the snapshot could be deleted (let's say, because
the snapshot is stuck in INIT or because it takes too much time to
upload all the initialization files for all snapshotted indices). If
the INIT snapshot is deleted, the snapshot-in-progress becomes ABORTED
but once the initialization in SnapshotService.beginSnapshot() finished
it is change back to STARTED state again.
This commit avoids an ABORTED snapshot to be started if it has been
deleted during initialization. It also adds a test that would have failed
with the previous behavior, and changes few method names here and there.
This commit changes some Azure tests so that they do not rely on
MockZenPing and TestZenDiscovery anymore, but instead use a mocked
AzureComputeService that exposes internal test cluster nodes as if
they were real Azure nodes.

Today we don't persist the global checkpoint when finishing a peer
recovery even though we advance an in memory value. This commit persists
the global checkpoint in RecoveryTarget#finalizeRecovery.
Closes#27861
Search response listeners should not be exposed in search plugin.
Support was added but reverted right after (not present in any release).
Though the SearchPlugin still contains a default definition for search response listeners
due to a broken revert. This change removes this extension point that is basically no-op.
In the case of nested aggregator this allows it to push down buffered child docs down to children aggregator.
Before this was done as part of the `NestedAggregator#getLeafCollector(...)`, but by then the children aggregators
have already moved on to the next segment and this causes incorrect results to be produced.
Closes#27912
* Limit the analyzed text for highlighting
- Introduce index level settings to control the max number of character
to be analyzed for highlighting
- Throw an error if analysis is required on a larger text
Closes#27517
Lucene TopDocs collector are now able to early terminate the collection
based on the index sort. This change plugs this new functionality directly in the
query phase instead of relying on a dedicated early terminating collector.
This is related to #27802. This commit adds a jar called
elasticsearch-nio that contains the base nio classes that will be used
for the tcp nio transport and eventually the http nio transport.
The jar does not depend on elasticsearch:core, so all references to core
have been removed.
Today when we get a metadata snapshot directly from a store directory,
we acquire a metadata lock, then acquire an IndexWriter lock. However,
we create a CheckIndex in IndexShard without acquiring the metadata lock
first. This causes a recovery failed because the IndexWriter lock can be
still held by method snapshotStoreMetadata. This commit makes sure to
create a CheckIndex under the metadata lock.
Closes#24481Closes#27731
Relates #24787
Previously to this change when DocStats are added together (for example when adding the index size of all primary shards for an index) we naively added the `totalSizeInBytes` together. This worked most of the time but not when the index size on one or multiple shards was reported to be `-1` (no value).
This change improves the logic by considering if the current value or the value to be added is `-1`:
* If the current and new value are both `-1` the value remains at `-1`
* If the current value is `-1` and the new value is not `-1`, current value is changed to be equal to the new value
* If the current value is not `-1` and the new value is `-1` the new value is ignored and the current value is not changed
* If both the current and new values are not `-1` the current value is changed to be equal to the sum of the current and new values.
The change also re-enables the failing rollover YAML test that was failing due to this bug.
We used to shrink the version map under an external lock. This is
quite ambigious and instead we can simply issue an empty refresh to
shrink it.
Closes#27852
Today we prevent that the same thread acquires the same lock more than once.
This restriction is a relict form the early days of this concurrency construct
and can be removed.
While the LiveVersionMap is an internal class that belongs to the engine we do
rely on some external locking to enforce the desired semantics. Yet, in tests
we mimic the outer locking but we don't have any way to enforce or assert on
that the lock is actually hold. This change moves the KeyedLock inside the
LiveVersionMap that allows the engine to access it as before but enables
assertions in the LiveVersionMap to ensure the lock for the modifying or
reading key is actually hold.
Currently FiltersAggregationBuilder#doRewrite creates a new FiltersAggregationBuilder which doesn't correctly copy the original "keyed" field if a non-keyed filter gets rewritten.
This can cause rendering bugs of the output aggregations like the one reported in #27841.
