Currently IndexAnalyzers keeps the three default as separate class members
although they should refer to the same analyzers held in the additional
analyzers map under the default names. This assumption should be made more
explicit by keeping all analyzers in the map. This change adapts the constructor
to check all the default entries are there and the getters to reach into the map
with the default names when needed.
The changes in #39317 brought to light some concurrency issues in the
close method of Recyclers as we do not wait for threads running in the
threadpool to be finished prior to the closing of the PageCacheRecycler
and the Recyclers that are used internally. #41695 was opened to
address the concurrent close issues but upon review, the closing of
these classes is not really needed as the instances should be become
available for garbage collection once there is no longer a reference to
the closed node.
Closes#41683
We have a number of places in analysis-handling code where we check
if a field type is a keyword field, and if so then extract the normalizer rather
than pulling the index-time analyzer. However, a keyword normalizer is
really just a special case of an analyzer, so we should be able to simplify this
by setting the normalizer as the index-time analyzer at construction time.
* This test was resulting in a `PARTIAL` instead of a `SUCCESS` state for
the case of closing an index during snapshotting on 7.x
* The reason for this is the changed default behaviour regarding
waiting for active shards between 8.0 and 7.x
* Fixed by adjusting the waiting behaviour on the close index request
in the test
* Closes#39828
* When close becomes true while the management pool is shut down, we run
into an unhandled `EsRejectedExecutionException` that fails tests
* Found this while trying to reproduce #32506
* Running the IndexStatsIT in a loop is a way of reproducing this
Previously, TransportSingleShardAction required constructing a new
empty response object. This response object's Streamable readFrom
was used. As part of the migration to Writeable, the interface here
was updated to leverage Writeable.Reader.
relates to #34389.
The close method in Node uses a StopWatch to time to closing of
various services. However, the call to log the timing was made before
any of the services had been closed and therefore no timing would be
printed out. This change moves the timing log call to be a closeable
that is the last item closed.
This change makes the default seed address tests account for the lack
of an IPv6 network. By default docker containers only run with IPv4 and
these tests fail in a vanilla installation of elasticsearch-ci. To
resolve this we only expect IPv6 seed addresses if IPv6 is available.

If the max doc in the index is greater than the minimum total term frequency
among the requested fields we need to adjust max doc to be equal to the min ttf.
This was removed by mistake when fixing #41125.
Closes#41934
The ReadOnlyEngine wraps its reader with a SoftDeletesDirectoryReaderWrapper if soft deletes
are enabled. However the wrapping is done on top of the ElasticsearchDirectoryReader and that
trips assertion later on since the cache key of these directories are different. This commit
changes the order of the wrapping to put the ElasticsearchDirectoryReader first in order to
ensure that it is always retrieved first when we unwrap the directory.
Closes#41795
* Allow unknown task time in QueueResizingEsTPE
The afterExecute method previously asserted that a TimedRunnable task
must have a positive execution time. However, the code in TimedRunnable
returns a value of -1 when a task time is unknown. Here, we expand the
logic in the assertion to allow for that possibility, and we don't
update our task time average if the value is negative.
* Add a failure flag to TimedRunnable
In order to be sure that a task has an execution time of -1 because of
a failure, I'm adding a failure flag boolean to the TimedRunnable class.
If execution time is negative for some other reason, an assertion will
fail.

Prior to this change the ISO8601 date parser would only
parse an optional timezone if seconds were specified.
This change moves the timezone to the same level of
optional components as hour, so that timestamps without
minutes or seconds may optionally contain a timezone.
It also adds a unit test to cover all the supported
formats.
Allows configuring the number of test iterations via IntelliJ's config dialog, instead of having to add it
manually via the tests.iters system property.
* terminated_early should always be set in the response with terminate_after
Today we set `terminated_early` to true in the response if the query terminated
early due to `terminate_after`. However if `terminate_after` is smaller than
the number of documents in a shard we don't set the flag in the response indicating
that the query was exhaustive. This change fixes this disprepancy by setting
terminated_early to false in the response if the number of documents that match
the query is smaller than the provided `terminate_after` value.
Closes#33949
Today Elasticsearch accepts, but silently ignores, port ranges in the
`discovery.seed_hosts` setting:
```
discovery.seed_hosts: 10.1.2.3:9300-9400
```
Silently ignoring part of a setting like this is trappy. With this change we
reject seed host addresses of this form.

Today if an exception is thrown when serializing a cluster state during
publication then the master enters a poisoned state where it cannot publish any
more cluster states, but nor does it stand down as master, yielding repeated
exceptions of the following form:

This is because it already created the publication request using
`CoordinationState#handleClientValue()` but then it fails before accepting it.
This commit addresses this by performing the serialization before calling
`handleClientValue()`.
Relates #41090, which was the source of such a serialization exception.
The fractional seconds portion of strict_date_optional_time was
accidentally copied from the printer, which always prints at least 3

Add a test that stresses concurrent writes using ifSeqno/ifPrimaryTerm to do CAS style updates. Use linearizability checker to verify linearizability. Linearizability of successful CAS'es is guaranteed.
Changed linearizability checker to allow collecting history concurrently.
Changed unresponsive network simulation to wake up immediately when network disruption is cleared to ensure tests proceed in a timely manner (and this also seems more likely to provoke issues).
Full text queries that start with now are not cacheable if they target a date field.
However we assume in the query builder tests that all queries are cacheable and this assumption
fails when the random generated query string starts with "now". This fails twice in several years
since the probability that a random string starts with "now" is low but this commit ensures that
isCacheable is correctly checked for full text queries that fall into this edge case.
Closes#41847
With this change, we will verify the consistency of version and source
(besides id, seq_no, and term) of live documents between shard copies
at the end of disruption tests.
If users close an index to change some non-dynamic index settings, then the current implementation forces replicas of that closed index to copy over segment files from the primary. With this change, we make peer recoveries of closed index skip both phases.

When Elasticsearch is run from a package installation, the running
process does not have permissions to write to the keystore. This is
because of the root:root ownership of /etc/elasticsearch. This is why we
create the keystore if it does not exist during package installation. If
the keystore needs to be upgraded, that is currently done by the running
Elasticsearch process. Yet, as just mentioned, the Elasticsearch process
would not have permissions to do that during runtime. Instead, this
needs to be done during package upgrade. This commit adds an upgrade
command to the keystore CLI for this purpose, and that is invoked during
package upgrade if the keystore already exists. This ensures that we are
always on the latest keystore format before the Elasticsearch process is
invoked, and therefore no upgrade would be needed then. While this bug
has always existed, we have not heard of reports of it in practice. Yet,
this bug becomes a lot more likely with a recent change to the format of
the keystore to remove the distinction between file and string entries.
Today you can add a null `Custom` to the cluster state or its metadata, but
attempting to publish such a cluster state will fail. Unfortunately, the
publication-time failure gives very little information about the source of the
problem. This change causes the failure to manifest earlier and adds
information about which `Custom` was null in order to simplify the
investigation.
Relates #41090.
This changes the error message for a negative result in a function score when
using the ln modifier to suggest using ln1p or ln2p when a negative result
occurs in a function score and for the log modifier to suggest using log1p or
log2p.
This relates to #41509
This commit is a refactoring of how we filter addresses on
interfaces. In particular, we refactor all of these methods into a
common private method. We also change the order of logic to first check
if an address matches our filter and then check if the interface is
up. This is to possibly avoid problems we are seeing where devices are
flapping up and down while we are checking for loopback addresses. We do
not expect the loopback device to flap up and down so by reversing the
logic here we avoid that problem on CI machines. Finally, we expand the
error message when this does occur so that we know which device is
flapping.
This is related to #27260. Currently there is a setting
http.read_timeout that allows users to define a read timeout for the
http transport. This commit implements support for this functionality
with the transport-nio plugin. The behavior here is that a repeating
task will be scheduled for the interval defined. If there have been
no requests received since the last run and there are no inflight
requests, the channel will be closed.
Today a bulk shard request appears as follows in the detailed task list:
requests[42], index[my_index]
This change adds the shard index and refresh policy too:
requests[42], index[my_index][2], refresh[IMMEDIATE]
If closing a shard while resetting engine,
IndexEventListener.afterIndexShardClosed would be called while there is
still an active IndexWriter on the shard. For integration tests, this
leads to an exception during check index called from MockFSIndexStore
.Listener. Fixed.
Relates to #38561
Today we allow adding entries from a file or from a string, yet we
internally maintain this distinction such that if you try to add a value
from a file for a setting that expects a string or add a value from a
string for a setting that expects a file, you will have a bad time. This
causes a pain for operators such that for each setting they need to know
this difference. Yet, we do not need to maintain this distinction
internally as they are bytes after all. This commit removes that
distinction and includes logic to upgrade legacy keystores.
Today we choose to initialize max_seq_no_of_updates on primaries only so
we can deal with a situation where a primary is on an old node (before
6.5) which does not have MUS while replicas on new nodes (6.5+).
However, this strategy is quite complex and can lead to bugs (for
example #40249) since we have to assign a correct value (not too low) to
MSU in all possible situations (before recovering from translog,
restoring history on promotion, and handing off relocation).
Fortunately, we don't have to deal with this BWC in 7.0+ since all nodes
in the cluster should have MSU. This change simplifies the
initialization of MSU by always assigning it a correct value in the
constructor of Engine regardless of whether it's a replica or primary.

IntervalsSources can throw IllegalArgumentExceptions if they would produce
