This test occasionally fails in `testCollectSearchShards` waiting on what seems
to be a search request to a remote cluster for one second. Given that the test
fails here very rarely I suspect maybe one second is very rarely not enough so
we could fix it by increasing the max wait time slightly.
Closes#33852
By moving DocStats into the engine we can easily cache the stats for
read-only engines if necessary. It also moves the responsibility out of IndexShard
which has quiet some complexity already.
The fix in #33757 introduces some workaround since FilterCodecReader didn't
support unwrapping. This cuts over to a more elegant fix to access the readers
segment infos.
This commit changes the random_score function to use the global docID of the document
rather than the segment docID to generate random scores. As a result documents that have
the same segment docID within the shard will generate different scores.
Add minimal sanity checks to custom/scripted similarities.
Lucene 8 introduced more constraints on similarities, in particular:
- scores must not be negative,
- scores must not decrease when term freq increases,
- scores must not increase when norm (interpreted as an unsigned long)
increases.
We can't check every single case, but could at least run some sanity checks.

* Profiler: Don’t profile NEXTDOC for ConstantScoreQuery.
A ConstantScore query will return the iterator of its inner query.
However, when profiling, the constant score query is wrapped separately
from its inner query, which distorts the times emitted by the profiler.
Return the iterator directly in such a case.
Closes#23430
The change in #27500 introduces this regression that causes `_get` and `_term_vector`
actions to run on the network thread if the realtime flag is set.
This fixes the issue by delegating to the super method forking on the corresponding threadpool.
We use similar / same concepts in SerachTransportService and HandledTransportAction but both
duplicate the efforts with slightly different implementation details. This streamlines
sending responses / exceptions back to a channel in an ActionListener with appropriate logging.
In #33241 we moved the file-based discovery functionality to core
Elasticsearch, but preserved the `discovery-file` plugin, and support for the
existing location of the `unicast_hosts.txt` file, for BWC reasons. This commit
completes the removal of this plugin.
New plugin for annotated_text field type.
Largely a copy of `text` field type but adds ability to include markdown-like syntax in the text.
The “AnnotatedText” class parses text+markup and converts into plain text and AnnotationTokens.
The annotation token values are injected unchanged alongside the regular text tokens to provide a
form of additional indexed overlay useful in positional searches and highlighting.
Annotated_text fields do not support fielddata as we want to phase this out.
Also includes a new "annotated" highlighter type that retains annotations and merges in search
hits as additional annotation markup.
Closes#29467
* MINOR: Drop Redundant Ctx. Check in ScriptService
* This check is completely redundant, the expression script
engine will throw anyway (and with a similar message) for
those contexts that it cannot compile. Moreover, the update context
is not the only context that is not suported by the expression engine
at this point so handling the update context separately here makes
no sense.
* Same fix idea as in #10666a4 to prevent background
threads trying to reconnect after the tests are done from
throwing `ExecutionCancelledException` and breaking the test
* Closes#30714
Allows to skip shard balancing when the cluster_concurrent_rebalance threshold is already reached, which cuts down the time spent in the rebalance method of BalancedShardsAllocator.
Currently `IndexMetadata#getCustomData(...)` wraps the custom metadata
in an unmodifiable map, but in case there is no entry for the specified
key then a NPE is thrown by Collections.unmodifiableMap(...). This is not
ideal in case callers like to throw an exception with a specific message.
(like in the case for ccr to indicate that the follow index was not created
by the create_and_follow api and therefor incompatible as follow index)
I think making `DiffableStringMap` itself immutable is better then just wrapping
custom metadata with `Collections.unmodifiableMap(...)` in all methods that access it.
Also removed the `equals()`, `hashcode()` and to `toString()` methods of
`DiffableStringMap`, because `AbstractMap` already implements these methods.
This commit switches the joda time backcompat in scripting to use
augmentation over ZonedDateTime. The augmentation methods provide
compatibility with the missing methods between joda's DateTime and
java's ZonedDateTime. Due to getDayOfWeek returning an enum in the java
API, ZonedDateTime is wrapped so that the method can return int like the
joda time does. The java time api version is renamed to
getDayOfWeekEnum, which will be kept through 7.x for compatibility while
users switch back to getDayOfWeek once joda compatibility is removed.
This commit adds a guard around the rare case that no documents in the
10 iterations actually have any values, thus making the warning check
incorrect.
closes#32779
This commit is a cleanup of the assertions in global checkpoint
listeners, simplifying them and adding some messages to them in case the
assertions trip.
When we add a global checkpoint listener, it is also carries along with
it a value that it thinks is the current global checkpoint. This value
can be above the actual global checkpoint on a shard if the listener
knows the global checkpoint from another shard copy (e.g., the primary),
and the current shard copy is lagging behind. Today we notify the
listener whenever the global checkpoint advances, regardless if it goes
above the current global checkpoint known to the listener. This commit
reworks this implementation. Rather than thinking of the value
associated with the listener as the current global checkpoint known to
the listener, we think of it as the value that the listener is waiting
for the global checkpoint to advance to (inclusive). Now instead of
notifying all waiting listeners when the global checkpoint advances, we
only notify those that are waiting for a value not larger than the
actual global checkpoint that we advanced to.
This is something that we were already doing when sorting by field, which is
now also done when sorting by score. As-is this change will speed up top-k
`term` queries. This could work for `match_all` queries as well when we
implement the `setMinCompetitiveScore` API on their Scorer.
The existing approach used date formatters when a format based string
like `date_time||epoch_millis` was used, instead of the custom code.
In order to properly solve this, a new interface called
`DateFormatter` has been added, which now can be implemented for custom
formatters. Currently there are two implementations, one using java time
and one doing the epoch_millis formatter, which simply parses a number
and then converts it to a date in UTC timezone.
The DateFormatter interface now also has a method to retrieve the name
of the formatter pattern, which is needed for mapping changes anyway.
The existing `CompoundDateTimeFormatter` class has been removed, the
name was not really nice anyway.
One more minor change is the fact, that the new java time using
FormatDateFormatter does not try to parse the date with its printer
implementation first (which might be a strict one and fail), but a
printer can now be specified in addition. This saves one potential
failure/exception when parsing less strict dates.
If only a printer is specified, the printer will also be used as a
parser.
This race can occur if the latch from the listener notifies the test
thread and the test thread races ahead before the scheduler thread has a
chance to emit the log message. This commit fixes this test by not
counting down the latch until after the log message we are going to
assert on has been emitted.
We used TimeoutException here but that's not serializable. This commit
switches to a serializable exception so that we can test for the
exception type on the remote side.
This change fixes a bug introduced in 6.3 that prevents fields with an explicit
similarity to be updated. It also adds a test that checks this case for similarities
but also for analyzers since they could suffer from the same problem.
Closes#33611
Today we use a special unicast hosts provider, the `MockUncasedHostsProvider`,
in many integration tests, to deal with the dynamic nature of the allocation of
ports to nodes. However #33241 allows us to use file-based discovery to achieve
the same goal, so the special test-only `MockUncasedHostsProvider` is no longer
required.
This change removes `MockUncasedHostProvider` and replaces it with file-based
discovery in tests based on `EsIntegTestCase`.
We fail to notify the resync listener if the resync replication hits a
shard unavailable exception. Moreover, we no longer need to swallow
these unavailable exceptions.

This field does not need to be volatile because all accesses are done
under a lock. This commit removes the unnecessary volatile modifier from
this field.
The remote cluster settings search.remote.* have been renamed to
cluster.remote.* and are automatically upgraded in the cluster state on
gateway recovery, and on put. This commit adds a note to the migration
docs for these changes.
This change adds a `_source` only snapshot repository that allows to wrap
any existing repository as a _backend_ to snapshot only the `_source` part
including live docs markers. Snapshots taken with the `source` repository
won't include any indices, doc-values or points. The snapshot will be reduced in size and
functionality such that it requires full re-indexing after it's successfully restored.
The restore process will copy the `_source` data locally starts a special shard and engine
to allow `match_all` scrolls and searches. Any other query, or get call will fail with and unsupported operation exception. The restored index is also marked as read-only.
This feature aims mainly for disaster recovery use-cases where snapshot size is
a concern or where time to restore is less of an issue.
**NOTE**: The snapshot produced by this repository is still a valid lucene index. This change doesn't allow for any longer retention policies which is out of scope for this change.
In cross-cluster replication, we will use global checkpoint listeners to
long poll for updates to a shard. However, we do not want these polls to
wait indefinitely as it could be difficult to discern if the listener is
still waiting for updates versus something has gone horribly wrong and
cross-cluster replication is stuck. Instead, we want these listeners to
timeout after some period (for example, one minute) so that they are
notified and we can update status on the following side that
cross-cluster replication is still active. After this, we will
immediately enter back into a poll mode.
To do this, we need the ability to associate a timeout with a global
checkpoint listener. This commit adds this capability.
This change clarifies the documentation of the context completion suggester
regarding filtering and boosting with contexts.
Unlike the suggester v1, filtering on multiple contexts
works as a disjunction, a suggestion matches if it contains at least one of the provided
context values and boosting selects the maximum score among the matching contexts.
This commit also adapts an old test that was written for the v1 suggester and commented out
for version 2 because the behavior changed.
This commit adds settings upgraders for the search.remote.* settings
that can be in the cluster state to automatically upgrade these settings
to cluster.remote.*. Because of the infrastructure that we have here,
these settings can be upgraded when recovering the cluster state, but
also when a user tries to make a dynamic update for these settings.
This commit adds test coverage for two cases not previously covered by
the existing testing. Namely, we add coverage ensuring that the executor
is used to notify listeners being added that are immediately notified
because the shard is closed or because the global checkpoint is already
beyond what the listener knows.
When a replica starts following a newly promoted primary, it may have
some operations which don't exist on the new primary. Thus we need to
throw those operations to align a replica with the new primary. This can
be done by first resetting an engine from the safe commit, then replaying
the local translog up to the global checkpoint.

Currently we keep track of how many bytes are currently being written to disk
in an AtomicLong within InternalEngine, updating it on refresh. The IndexWriter
has its own accounting for this, and exposes it via a getFlushingBytes method
in the latest lucene 8 snapshot. This commit removes the InternalEngine tracking
in favour of just using the IndexWriter method.
Upgrading list settings is broken because of the conversion that we do
to strings, and then when we try to put back the upgraded value we do
not know that it is a representation of a list. This commit addresses
this by adding special handling for list settings.

When we see a settings value, it could be a list. Yet this should only
happen if the underlying setting type is a list setting type. This
commit adds validation that when we get a setting value that is a list,
that the setting that we are getting is a list setting. And similarly,
if we get a value for a list setting, the underlying value should be a
list.
This change copies and validates the soft-deletes setting during resize.
If the source enables soft-deletes, the target must also enable it.

Today the FilterRoutingTests take the belt-and-braces approach of excluding
some node attribute values and including some others. This means that we don't
really test that both inclusion and exclusion work correctly: as long as one of
them works as expected then the test will pass. This change improves these
tests by only using one approach at once, demonstrating that both do indeed
work, and adds tests for various other scenarios too.
In some cases we want to deprecate a setting, and then automatically
upgrade uses of that setting to a replacement setting. This commit adds
infrastructure for this so that we can upgrade settings when recovering
the cluster state, as well as when such settings are dynamically applied
on cluster update settings requests. This commit only focuses on cluster
settings, index settings can build on this infrastructure in a
follow-up.
This commit ensures that we bootstrap a new history_uuid when force
allocating a stale primary. A stale primary should never be the source
of an operation-based recovery to another shard which exists before the
forced-allocation.

Today when checking settings dependencies, we do not check if fallback
settings are present. This means, for example, that if
cluster.remote.*.seeds falls back to search.remote.*.seeds, and
cluster.remote.*.skip_unavailable and search.remote.*.skip_unavailable
depend on cluster.remote.*.seeds, and we have set search.remote.*.seeds
and search.remote.*.skip_unavailable, then validation will fail because
it is expected that cluster.ermote.*.seeds is set here. This commit
addresses this by also checking fallback settings when validating
dependencies. To do this, we adjust the settings exist method to also
check for fallback settings, a case that it was not handling previously.
Change the logging infrastructure to handle when the node name isn't
available in `elasticsearch.yml`. In that case the node name is not
available until long after logging is configured. The biggest change is
that the node name logging no longer fixed at pattern build time.
Instead it is read from a `SetOnce` on every print. If it is unset it is
printed as `unknown` so we have something that fits in the pattern.
On normal startup we don't log anything until the node name is available
so we never see the `unknown`s.
We invoke force merge twice in the test to verify that recovery sources
are pruned when the global checkpoint advanced. However, if the global
checkpoint equals to the local checkpoint in the first force-merge, the
second force-merge will be a noop because all deleted docs are expunged
in the first merge already. We need to flush a new segment to make merge
happen so we can verify that all recovery sources are pruned.
Instead of passing DirectoryService which causes yet another dependency
on Store we can just pass in a Directory since we will just call
`DirectoryService#newDirectory()` on it anyway.
This change collapses all metrics aggregations classes into a single package `org.elasticsearch.aggregations.metrics`.
It also restricts the visibility of some classes (aggregators and factories) that should not be used outside of the package.

When we rollover and index we write the conditions of the rollover that
the old index met into the old index. Loading this index metadata
requires a working `NamedXContentRegistry` that has been populated with
parsers from the rollover infrastructure. We had a few loads that didn't
use a working `NamedXContentRegistry` and so would fail if they ever
encountered an index that had been rolled over. Here are the locations
of the loads and how I fixed them:
* IndexFolderUpgrader - removed entirely. It existed to support opening
indices made in Elasticsearch 2.x. Since we only need this change as far
back as 6.4.1 which will supports reading from indices created as far
back as 5.0.0 we should be good here.
* TransportNodesListGatewayStartedShards - wired the
`NamedXContentRegistry` into place.
* TransportNodesListShardStoreMetaData - wired the
`NamedXContentRegistry` into place.
* OldIndexUtils - removed entirely. It existed to support the zip based
index backwards compatibility tests which we've since replaced with code
that actually runs old versions of Elasticsearch.
In addition to fixing the actual problem I added full cluster restart
integration tests for rollover which would have caught this problem and
I added an extra assertion to IndexMetaData's deserialization code which
will trip if we try to deserialize and index's metadata without a fully
formed `NamedXContentRegistry`. It won't catch if use the *wrong*
`NamedXContentRegistry` but it is better than nothing.

With this commit we use the classic parent circuit breaker which does
not account for real memory usage. In those tests we want to have
reproducible results and hence it makes sense to disable the real memory
circuit breaker there.
Auto Following Patterns is a cross cluster replication feature that
keeps track whether in the leader cluster indices are being created with
names that match with a specific pattern and if so automatically let
the follower cluster follow these newly created indices.
This change adds an `AutoFollowCoordinator` component that is only active
on the elected master node. Periodically this component checks the
the cluster state of remote clusters if there new leader indices that
match with configured auto follow patterns that have been defined in
`AutoFollowMetadata` custom metadata.
This change also adds two new APIs to manage auto follow patterns. A put
auto follow pattern api:
```
PUT /_ccr/_autofollow/{{remote_cluster}}
{
"leader_index_pattern": ["logs-*", ...],
"follow_index_pattern": "{{leader_index}}-copy",
"max_concurrent_read_batches": 2
... // other optional parameters
}
```
and delete auto follow pattern api:
```
DELETE /_ccr/_autofollow/{{remote_cluster_alias}}
```
The auto follow patterns are directly tied to the remote cluster aliases
configured in the follow cluster.

Historically we have had a ESLoggingHandler in the netty module that
logs low-level connection operations. This class just extends the netty
logging handler with some (broken) message deserialization. This commit
fixes this message serialization and moves the class to server.
This new logger logs inbound and outbound messages. Eventually, we
should move other event logging to this class (connect, close, flush).
That way we will have consistent logging regards of which transport is
loaded.
Resolves#27306 on master. Older branches will need a different fix.
This commit is related to #32517. It allows an "server_name"
attribute on a DiscoveryNode to be propagated to the server using
the TLS SNI extentsion. This functionality is only implemented for
the netty security transport.
This change adds an expert index setting called `index.merge.policy.deletes_pct_allowed`.
It controls the maximum percentage of deleted documents that is tolerated in the index.
Lower values make the index more space efficient at the expense of increased CPU and I/O activity.
Values must be between `20` and `50`. Default value is `33`.
Drops and unused logging constructor, simplifies a rarely used one, and
removes `Settings` from a third. There is now only a single logging ctor
that takes `Settings` and we'll remove that one in a follow up change.
The maximum number of fields per index is limited to 1000 by default by the
`index.mapping.total_fields.limit` setting to prevent accidental mapping
explosions due to too many fields. Currently all metadata fields also count
towards this limit, which can lead to some confusion when using lower limits.
It is not obvious for users that they cannot actually add as many fields as
are specified by the limit in this case.
This change takes the number of metadata fields out of the field count that we
check against the field limit. It also adds tests that check that we can add
fields up to the specified limit, but throw an exception for any additional field added.
Closes#24096
Deprecating a some setting specializations (e.g., list settings) does
not cause deprecation warning headers and deprecation log messages to
appear. This is due to a missed check for deprecation. This commit fixes
this for all setting specializations, and ensures that this can not be
missed again.
Adds a place for users to store cluster-wide data they wish to associate
with the cluster via the Cluster Settings API. This is strictly for
user-defined data, Elasticsearch makes no other other use of these
settings.
Now that types are unique per mapping we can retrieve the document mapper
without referencing the type. This fixes an NPE when stored fields are disabled.
For 6x we'll need a different fix since mappings can still have multiple types.

This commit introduces the formal notion of a private setting. This
enables us to register some settings that we had previously not
registered as fully-fledged settings to avoid them being exposed via
APIs such as the create index API. For example, we had hacks in the
codebase to allow index.version.created to be passed around inside of
settings objects, but was not registered as a setting so that if a user
tried to use the setting on any API then they would get an
exception. This prevented users from setting index.version.created on
index creation, or updating it via the index settings API. By
introducing private settings, we can continue to reject these attempts,
yet now we can represent these settings as actual settings. In this
change, we register index.version.created as an actual setting. We do
not cutover all settings that we had been treating as private in this
pull request, it is already quite large due to moving some tests around
to account for the fact that some tests need to be able to set the
index.version.created. This can be done in a follow-up change.

We can have multiple documents in Lucene with the same seq_no for

The existing implemention could not deal with negative numbers as well
as +- 999 milliseconds around the epoch.
This commit uses Instant.ofEpochMilli() and parses the input to
a number instead of using a date formatter.
This commit adds the support to early terminate the collection of a leaf
in the aggregation framework. This change introduces a MultiBucketCollector which
handles CollectionTerminatedException exactly like the Lucene MultiCollector.
Any aggregator can now throw a CollectionTerminatedException without stopping
the collection of a sibling aggregator. This is useful for aggregators that
can infer their result without visiting all documents (e.g.: a min/max aggregation on a match_all query).
Drops `Settings` from some logging ctors now that they are no longer
needed. This should allow us to stop passing `Settings` around to quite
as many places.

This PR removes the deprecated `Custom` class in `IndexMetaData`, in favor
of a `Map<String, DiffableStringMap>` that is used to store custom index
metadata. As part of this, there is now no way to set this metadata in a
template or create index request (since it's only set by plugins, or dedicated
REST endpoints).
The `Map<String, DiffableStringMap>` is intended to be a namespaced `Map<String,
String>` (`DiffableStringMap` implements `Map<String, String>`, so the signature
is more like `Map<String, Map<String, String>>`). This is so we can do things
like:
``` java
Map<String, String> ccrMeta = indexMetaData.getCustom("ccr");
```
And then have complete control over the metadata. This also means any
plugin/feature that uses this has to manage its own BWC, as the map is just
serialized as a map. It also means that if metadata is put in the map that isn't
used (for instance, if a plugin were removed), it causes no failures the way
an unregistered `Setting` would.
The reason I use a custom `DiffableStringMap` here rather than a plain
`Map<String, String>` is so the map can be diffed with previous cluster state
updates for serialization.
Supersedes #32683
We cut over to `index.resize.source.*` but still have these constants
being public in `IndexMetaData`. Those Settings and constants are not needed
in 7.x while we still need to keep the keys known to private settings since
they might be part of the index settings of old indices. We can remove that
in 8.0. Yet, we should remove the settings to make sure they are not used again.
Fix serialization of empty field capabilities response

If an exclude or an include clause removes an entry to a nested field in the original source at query time,
the creation of nested hits fails with an NPE. This change fixes this exception and replaces the nested document
source with an empty map.

Today we add a NoOp to Lucene and translog if we fail to process an
indexing operation. However, we are only adding NoOps to translog for
delete operations. In order to have a complete history in Lucene, we
should add NoOps of failed delete operations to both Lucene and translog.

Today we support a static list of seed hosts in core Elasticsearch, and allow a
dynamic list of seed hosts to be provided via a file using the `discovery-file`
plugin. In fact the ability to provide a dynamic list of seed hosts is
increasingly useful, so this change moves this functionality to core
Elasticsearch to avoid the need for a plugin.
Furthermore, in order to start up nodes in integration tests we currently
assign a known port to each node before startup, which unfortunately sometimes
fails if another process grabs the selected port in the meantime. By moving the
`discovery-file` functionality into the core product we can use it to avoid
this race.
This change also moves the expected path to the file from
`$ES_PATH_CONF/discovery-file/unicast_hosts.txt` to
`$ES_PATH_CONF/unicast_hosts.txt`. An example of this file is not included in
distributions.
For BWC purposes the plugin still exists, but does nothing more than create the
example file in the old location, and issue a warning when it is used. We also
continue to support the old location for the file, but warn about its
deprecation.

Some settings have filters applied to them and we use this in logs and
the get nodes info API. For consistency, we should apply this in the get
cluster settings API too.

The shrink action was renamed to `_resize` with the addition
or split. This bwc layer is unnecessary on 7.x since 6.latest will
always use the resize action.
We have had support for the `group_shard_failures` parameter in our code for a while, since we introduced failures grouping. When we introduced validation of parameters at REST, we seem to have forgotten to expose such parameter. Given that the parameter is effectively not supported for many months now, that no user has complained about that and that grouping is the expected behaviour, this commit removes support for the parameter.
`BucketUtils#suggestShardSideQueueSize` used to calculate the shard_size based on the number of shards. It returns now a different value only based on whether we are querying a single shard or multiple shards. This commit replaces the numberOfShards argument with a boolean that tells whether we are querying a single shard or not.
Exclude classes meant for newer versions than what we are auditing against, those classes won't be found. There's no reason to exclude JDK classes from newer versions, with this PR, we will not extract them in the first place.

Today a file-based recovery will replay all existing translog operations
from the primary on a replica so that that replica can have a full
history in translog as the primary. However, with soft-deletes enabled,
we should not do it because:
1. All operations before the local checkpoint of the safe commit exist in
the commit already.
2. The number of operations before the local checkpoint may be considerable
and requires a significant amount of time to replay on a replica.

This commit makes primary-replica resyncer use Lucene as the source of
history operation instead of translog if soft-deletes is enabled. With
this change, we no longer expose translog snapshot directly in IndexShard.

The new implementation is functional equivalent with the old, ant based one.
It parses task standard error to get the missing classes and violations in the same way.
I considered re-using ForbiddenApisCliTask but Gradle makes it hard to build inheritance with tasks that have task actions , since the order of the task actions can't be controlled.
This inheritance isn't dully desired either as the third party audit task is much more opinionated and we don't want to expose some of the configuration.
We could probably extract a common base class without any task actions, but probably more trouble than it's worth.
