This fixes a bug about aliases authorization.
That is, a user might see aliases which he is not authorized to see.
This manifests when the user is not authorized to see any aliases
and the `GetAlias` request is empty which normally is a marking
that all aliases are requested. In this case, no aliases should be
returned, but due to this bug, all aliases will have been returned.
The `ignore` set contains entries of type Class<?>, but the check is performed
on Path objects. This always returns false so is useless currently. Looking at
the first commit of this test that already shows this behaviour this never
excluded anything, so it can be removed.
This change introduces stats per processors. Total, time, failed,
current are currently supported. All pipelines will now show all
top level processors that belong to it. Failure processors are not
displayed, however, the time taken to execute the failure chain is part
of the stats for the top level processor.
The processor name is the type of the processor, ordered as defined in
the pipeline. If a tag for the processor is found, then the tag is
appended to the type.
Pipeline processors will have the pipeline name appended to the name of
the name of the processors (before the tag if one exists). If more
then one pipeline is used to process the document, then each pipeline
will carry its own stats. The outer most pipeline will also include the
inner most pipeline stats.
Conditional processors will only included in the stats if the condition evaluates
to true.
Adds checks for parsed geo distance query. It is a bit hack-ish since it
compares with query's toString() output, but it is better than no
checks. The parsed query itself has default visibility, so we cannot
access it here unless we move the test to org.apache.lucene.document
package.

Since #34288, we might hit deadlock if the FollowTask has more fetchers
than writers. This can happen in the following scenario:
Suppose the leader has two operations [seq#0, seq#1]; the FollowTask has
two fetchers and one writer.
1. The FollowTask issues two concurrent fetch requests: {from_seq_no: 0,
num_ops:1} and {from_seq_no: 1, num_ops:1} to read seq#0 and seq#1
respectively.
2. The second request which fetches seq#1 completes before, and then it
triggers a write request containing only seq#1.
3. The primary of a follower fails after it has replicated seq#1 to
replicas.
4. Since the old primary did not respond, the FollowTask issues another
write request containing seq#1 (resend the previous write request).
5. The new primary has seq#1 already; thus it won't replicate seq#1 to
replicas but will wait for the global checkpoint to advance at least
seq#1.
The problem is that the FollowTask has only one writer and that writer
is waiting for seq#0 which won't be delivered until the writer completed.
This PR proposes to replicate existing operations with the old primary
term (instead of the current term) on the follower. In particular, when
the following primary detects that it has processed an process already,
it will look up the term of an existing operation with the same seq_no
in the Lucene index, then rewrite that operation with the old term
before replicating it to the following replicas. This approach is
wait-free but requires soft-deletes on the follower.

The shard suggestion sort uses a different tie-break than the one that is used
to merge different shards responses. The former uses the internal document identifier
when scores are the same whereas the latter compares the surface form first.
Because of this discrepancy some suggestion outputs are linked to the wrong documents
because the merge sort reorders the shard suggestions differently. This change
fixes this bug by duplicating the Lucene collector in order to be able to apply the
same tiebreak strategy than the merge sort. This logic will be removed when
https://issues.apache.org/jira/browse/LUCENE-8529 is fixed.
Closes#34378
Today we rely on the LocalCheckpointTracker to ensure no duplicate when
enabling optimization using max_seq_no_of_updates. The problem is that
the LocalCheckpointTracker is not fully reloaded when opening an engine
with an out-of-order index commit. Suppose the starting commit has seq#0
and seq#2, then the current LocalCheckpointTracker would return "false"
when asking if seq#2 was processed before although seq#2 in the commit.
This change scans the existing sequence numbers in the starting commit,
then marks these as completed in the LocalCheckpointTracker to ensure
the consistent state between LocalCheckpointTracker and Lucene commit.
Exclusion setting `cluster.routing.allocation.exclude._host` default value
is an empty string.
When an exclusion setting is sent with a null value the
o.e.c.s.Setting#innerGetRaw API return an empty string (probably to
avoid a NullPointerException to be raised).
The o.e.c.r.a.d.FilterAllocationDecider class is developed to omit
updates of default values for exclusion setting.
That's why a null exclusion setting value is translated to an empty
string which is equals to the exclusion default value which is
configured to be ignored.
A simple fix would be to not omit default values for exclusion setting
and keep the NullPointerException guard. This is the purpose of this
commit.
Closes#32721
The `term` and `phrase` suggesters have different options to filter candidates
based on their frequencies. The `popular` mode for instance filters candidate
terms that occur in less docs than the original term. However when we compute this threshold
we use the total term frequency of a term instead of the document frequency. This is not inline
with the actual filtering which is always based on the document frequency. This change fixes
this discrepancy and clarifies the meaning of the different frequencies in use in the suggesters.
It also ensures that the threshold doesn't overflow the maximum allowed value (Integer.MAX_VALUE).
Closes#34282
With this commit we cleanup hand-coded duplicate checks in XContent
parsing. They were necessary previously but since we reconfigured the
underlying parser in #22073 and #22225, these checks are obsolete and
were also ineffective unless an undocumented system property has been
set. As we also remove this escape hatch, we can remove the additional
checks as well.

In order to stay BWC compatible with joda time, the epoch millis date
formatter needs to parse dates with a dot like `123.45`. This
adds this functionality for the epoch millis parser in the same way as
for the epoch seconds parser. It also adds support for scientific
notations like `1.0e3` and fixes parsing of negative values for epoch
seconds and epoch millis.
When we upgrade an index, we set the settings version upgraded
setting. This should be considered a settings change, and therefore we
need to increment the settings version. This commit addresses that.
Applies our line length guidance for all classes in the server in `lucene`
directories *except* `XMoreLikeThis`. The only long line in
`XMoreLikeThis` says "remove this when we upgrade to Lucene 5. Given
that we're on Lucene 8, this is a little terrifying and deserves another
look.
In remote cluster setup if we see a configured proxy we should set
the seed nodes host name as the `server_name` to trigger SNI based
routing even for seed nodes. Since remote cluster connections are
plain TCP connections we have to set the host manually since the other
side can't take it from the request URL like in the HTTP case.
This also adds some more informative logging to remote cluster connection.
in #28741 RolloverIT fails because we are cutting over to the
next day while the test executes. We assume that this doesn't happen
based on the assertions in the test. This adds a assumeTrue to ensure
we are at least 5 min away form a date-flip.
Closes#28741
`Engine.Searcher` is non-final today which makes it error prone
in the case of wrapping the underlying reader or lucene `IndexSearcher`
like we do in `IndexSearcherWrapper`. Yet, there is no subclass of it yet
that would be dramatic to just drop on the floor. With the start of development
of frozen indices this changed since in #34357 functionality was added to
a subclass which would be dropped if a `IndexSearcherWrapper` is installed on an index.
This change locks down the `Engine.Searcher` to prevent such a functionality trap.
The `AutoFollowTests` needs to restart the clusters between each tests, because
it is using auto follow stats in assertions. Auto follow stats are only reset
by stopping the elected master node.
Extracted the `testGetOperationsBasedOnGlobalSequenceId()` test to its own test, because it just tests the shard changes api.
* Renamed AutoFollowTests to AutoFollowIT, because it is an integration test.
Renamed ShardChangesIT to IndexFollowingIT, because shard changes it the name
of an internal api and isn't a good name for an integration test.
* move creation of NodeConfigurationSource to a seperate method
* Fixes issues after merge, moved assertSeqNos() and assertSameDocIdsOnShards() methods from ESIntegTestCase to InternalTestCluster, so that ccr tests can use these methods too.
This change disallows negative query boosts. Negative scores are not allowed in Lucene 8 so
it is easier to just disallow negative boosts entirely. We should also deprecate negative boosts
in 6x in order to ensure that users are aware when they'll upgrade to ES 7.

This commit introduces settings version to index metadata. This value is
monotonically increasing and is updated on settings updates. This will
be useful in cross-cluster replication so that we can request settings
updates from the leader only when there is a settings update.
Today when submitting an update settings request to update the number of
replicas with a wildcard that does not match any indices and allow no
indices is set to true, the request ends up being interpreted as
updating the number of replicas for all indices. That is, consider the
following sequence:
PUT /test-index
{
"settings": {
"index.number_of_replicas": 0
}
}
PUT /non-existent-*/_settings?expand_wildcards=open&allow_no_indices=true
{
"settings": {
"index.number_of_replicas": 1
}
}
GET /test-index/_settings
The latter will show that the number of replicas on test-index is now
one. This is surprising, and should be considered a bug.
The underlying problem here is treating no indices in the underlying
methods used to update the routing table and the metadata as meaning all
indices. This commit takes away this assumption. Tests that relied on
this behavior have been changed to no longer rely on this.
A test for this situation is added in UpdateNumberOfReplicasIT.
This removes another two methods from `AbstractComponent`. One isn't
used at all and another is only used in a single class in watcher. I've

This commit handles cases testing withLocale and withZone when the zone
and locale in question is the same as the special base case. This can
happen sometimes since the locale and zoneids are randomized.
Empty values on keyword fields are filtered by the `map` execution mode

Closes#34434
This commit removes randomization of locale for DateFormatter equals
tests, instead using explicit locales. The test framework already
randomizes locales, so the random choice of the second locale can
sometimes be equal to the already chosen locale. Randomization also does
not provide any extra protection, as the equality of DateFormatter does
not implement equality of the locales itself.

ListenableFuture may run a listener on the same thread that called the
addListener method or it may execute on another thread after the future
has completed. Whenever the ListenableFuture stores the listener for
execution later, it should preserve the thread context which is what
this change does.
Today we rewrite the operations from the leader with the term of the
following primary because the follower should own its history. The
problem is that a newly promoted primary may re-assign its term to
operations which were replicated to replicas before by the previous
primary. If this happens, some operations with the same seq_no may be
assigned different terms. This is not good for the future optimistic
locking using a combination of seqno and term.
This change ensures that the primary of a follower only processes an
operation if that operation was not processed before. The skipped
operations are guaranteed to be delivered to replicas via either
primary-replica resync or peer-recovery. However, the primary must not
acknowledge until the global checkpoint is at least the highest seqno of
all skipped ops (i.e., they all have been processed on every replica).

Questions on how to work with `ActionPlugin#getRestHandlerWrapper()`
come up in discuss forums all the time. This change adds an example
to the javadoc how this method should/could be used.
ES is scanning for dangling indices on every cluster state update. For this, it lists the subfolders of
the indices directory to determine which extra index directories exist on the node where there's no
corresponding index in the cluster state. These are potential targets for dangling index import. On
certain machine types, and with large number of indices, this subfolder listing can be horribly slow.
This means that every cluster state update will be slowed down by potentially hundreds of
milliseconds. One of the reasons for this poor performance is that Files.isDirectory() is a relatively
expensive call on some OS and JDK versions. There is no need though to do all these isDirectory
calls for folders which we know we are going to discard anyhow in the next step of the dangling
indices logic. This commit allows adding an exclusion predicate to the availableIndexFolders
methods which can dramatically speed up this method when scanning for dangling indices.
Since all calls to `ESLoggerFactory` outside of the logging package were
deprecated, it seemed like it'd simplify things to migrate all of the
deprecated calls and declare `ESLoggerFactory` to be package private.
This does that.
With this commit we restore the previous behavior in
`BigArraysTests#testMaxSizeExceededOnResize` but lower the sizes that
are tested to the range between 256 bytes to 16 kB so the test does not
produce a whole lot of garbage.
The previous attempt to reduce the amount of garbage produced by that
test was to properly size the array initially but it failed to account
for object alignment which lead to test failures in some cases. While it
would be possible to account for object alignment, we would need to open
up BigArrays or directly use the underlying Lucene API which would
require us to allocate an array upfront only to find its size (incl.
object alignment).
Instead we have fixed this issue by conservatively sizing the array
initially (so the initial allocation will never trip the circuit
breaker) and reduce garbage by reducing the circuit breaker's upper
bound as described previously.

This changes the delete job API by adding
the choice to delete a job asynchronously.
The commit adds a `wait_for_completion` parameter
to the delete job request. When set to `false`,
the action returns immediately and the response
contains the task id.
This also changes the handling of subsequent
delete requests for a job that is already being
deleted. It now uses the task framework to check
if the job is being deleted instead of the cluster
state. This is a beneficial for it is going to also
be working once the job configs are moved out of the
cluster state and into an index. Also, force delete
requests that are waiting for the job to be deleted
will not proceed with the deletion if the first task
fails. This will prevent overloading the cluster. Instead,
the failure is communicated better via notifications
so that the user may retry.
Finally, this makes the `deleting` property of the job
visible (also it was renamed from `deleted`). This allows
a client to render a deleting job differently.
Closes#32836
The `status` part of the tasks API reflects the internal status of a
running task. In general, we do not make backwards breaking changes to
the `status` but because it is internal we reserve the right to do so. I
suspect we will very rarely excercise that right but it is important
that we have it so we're not boxed into any particular implementation
for a request.
In some sense this is policy making by documentation change. In another
it is clarification of the way we've always thought of this field.
I also reflect the documentation change into the Javadoc in a few
places. There I acknowledge Kibana's "special relationship" with
Elasticsearch. Kibana parses `_reindex`'s `status` field and, because
we're friends with those folks, we should talk to them before we make
backwards breaking changes to it. We *want* to be friends with everyone
but there is only so much time in the day and we don't *want* to make
backwards breaking fields to `status` at all anyway. So we hope that
breaking changes documentation should be enough for other folks.

Drops the last logging constructor that takes `Settings` because it is
no longer needed.
Watcher goes through a lot of effort to pass `Settings` to `Logger`
constructors and dropping `Settings` from all of those calls allowed us
to remove quite a bit of log-based ceremony from watcher.
Today we use the version of a DirectoryReader as a component of the key
of IndicesRequestCache. This usage is perfectly fine since the version
is advanced every time a new change is made into IndexWriter. In other
words, two DirectoryReaders with the same version should have the same
content. However, this invariant is only guaranteed in the context of a
single IndexWriter because the version is reset to the committed version
value when IndexWriter is re-opened.
Since #33473, each IndexShard may have more than one IndexWriter, and
using the version of a DirectoryReader as a part of the cache key can
cause IndicesRequestCache to return stale cached values. For example, in
#27650, we rollback the engine (i.e., re-open IndexWriter), index new
documents, refresh, then make a count request, but the search layer
mistakenly returns the count of the DirectoryReader of the previous
IndexWriter because the current DirectoryReader has the same version of
the old DirectoryReader even their documents are different. This is
possible because these two readers come from different IndexWriters.
This commit replaces the the version with the reader cache key of
IndexReader as a component of the cache key of IndicesRequestCache.

This commit adds the support to early terminate the collection of a leaf

* Add breaking change details to PR
Today we reverse the initial order of the nested documents when we
index them in order to ensure that parents documents appear after
their children. This means that a query will always match nested documents
in the reverse order of their offsets in the source document.
Reversing all documents is not needed so this change ensures that parents
documents appear after their children without modifying the initial order
in each nested level. This allows to match children in the order of their
appearance in the source document which is a requirement to efficiently
implement #33587. Old indices created before this change will continue
to reverse the order of nested documents to ensure backwark compatibility.
* Adds trace logging to IndicesRequestCache
This change adds trace level logging to `IndicesrrequestCache` witht eh
primary aim of helping to identify the cause of teh failures in
https://github.com/elastic/elasticsearch/issues/32827. The cache will
log at trace level when a cache hit or miss occurs including the reader
version and the cache key. Note that this change adds a
`cacheKeyRenderer` whcih supplies a human readable String of the cache
key since the actual cache key itself is a `BytesReference` containing
the wire protocol serialised form of the request.
Logging is also added for the case where a search timeout occurs and fr
that reason the cache entry is invalidated.
* Adds comment to remaind us to remove cacheKeyRenderer
In #28941 we changed the computation of cluster state task descriptions but
this introduced a bug in which we only log the empty descriptions (rather than
the non-empty ones). This change fixes that.
Optionals containing boxed primitive types are prohibitively costly because they

This adds some method into the `DateFormatter` interface, namely
* `withLocale()` to change the locale of a date formatter
* `getLocale()`
* `getZone()`
* `hashCode()`
* `equals()`
These methods will be needed for aggregations and mapping changes, where
zones and locales can be specified in the mapping or in search/aggs
parts of a search request.
When nested objects are present in the mappings, we add a filter in
queries to exclude them if there is no evidence that the query cannot
match in this space. In 6x we visit the query in order to find a mandatory
clause that can match root documents only. If we find one we can omit the
nested documents filter. Currently only `term` and `range` queries are checked,
this change adds the support for `terms` query to effectively remove the nested filter
if a mandatory `terms` clause targets a non-nested field.

This commit removes the use of ExecutableScript from watcher in favor of
custom script contexts for both watcher condition scripts and transform
scripts.
Fixes the equals and hash function to ignore the order of aggregations to ensure equality after serialization
and deserialization. This ensures storing configs with aggregation works properly.
This also addresses a potential issue in caching when the same query contains aggregations but in
different order. 1st it will not hit in the cache, 2nd cache objects which shall be equal might end up twice in
the cache.
In order to be compatible with joda time, this adds an epoch seconds
formatter, that is able to parse floating point values.
However joda time discards the floating point values, but still parses

milliseconds.
The synonym filters no longer need access to the AnalysisRegistry in their

This commit adds the ability to plug in compilation of custom contexts

Prior to this change when a pipeline processor called another
pipeline, only the stats for the first processor were recorded.
The stats for the subsequent pipelines were ignored. This change
properly accounts for pipelines irregardless if they are the first
or subsequently called pipelines.
This change moves the state of the stats from the IngestService
to the pipeline itself. Cluster updates are safe since the pipelines
map is atomically swapped, and if a cluster update happens
while iterating over stats (now read directly from the pipeline)
a slightly stale view of stats may be shown.
Recently we introduced the settings cluster.remote to take the place of
search.remote for configuring remote cluster connections. We made this
change due to the fact that we have generalized the remote cluster
infrastructure to also be used within cross-cluster replication and not
only cross-cluster search. For backwards compatibility, when we made this
change, we allowed that cluster.remote would fallback to
search.remote. Alas, the initial change for this contained a bug for
handling the proxy and seeds settings. The bug for the seeds settings
arose because we were manually iterating over the concrete settings only
for cluster.remote seeds but not for search.remote seeds. This commit
addresses this by iterating over both cluster.remote seeds and
search.remote seeds. Additionally, when checking for existence of proxy
settings, we have to not only check cluster.remote proxy settings, but
also fallback to search.remote proxy settings. This commit addresses
both issues, and adds tests for these situations.
* Handle MatchNoDocsQuery in span query wrappers
This change adds a new SpanMatchNoDocsQuery query that replaces
MatchNoDocsQuery in the span query wrappers.
The `wildcard` query now returns MatchNoDocsQuery if the target field is not

be able to pass it to other span wrappers.
