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.
Relates #30522
Relates #29530
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.
Closes#31715
We generate slightly different NoOps in InternalEngine and
TransportShardBulkAction for the same failure.
1. InternalEngine uses Exception#getFailure to generate a message
without the class name: newOp [NoOp{seqNo=1, primaryTerm=1,
reason='Contexts are mandatory in context enabled completion field
[suggest_context]'}].
2. TransportShardBulkAction uses Exception#toString to generate a
message with the class name: NoOp{seqNo=1, primaryTerm=1,
reason='java.lang.IllegalArgumentException: Contexts are mandatory in
context enabled completion field [suggest_context]'}.
If a write operation fails while a replica is recovering, that replica
will possibly receive two different NoOps: one from recovery and one
from replication. These two different NoOps will trip
TranslogWriter#assertNoSeqNumberConflict assertion.
This commit ensures that we generate the same Noop for the same failure.
Closes#32986
As part of recent changes made to `ShardOperationFailedException` we introduced `index` and `shardId` members to the base class, but the subclasses are entirely responsible for the serialization of such fields. In the case of `ShardSearchFailure`, we have an additional `SearchShardTarget` instance member which also holds the index and the shardId, hence they get serialized as part of `SearchShardTarget` itself. When de-serializing a `ShardSearchFailure` though, we need to remember to also set the parent class `index` and `shardId` fields otherwise they get lost

The introduction of mapping version on index metadata has been
backported to 6.x. This commit adjusts the BWC version around mapping
version to account for this backport.
This commit introduces mapping version to index metadata. This value is
monotonically increasing and is updated on mapping updates. This will be
useful in cross-cluster replication so that we can request mapping
updates from the leader only when there is a mapping update as opposed
to the strategy we employ today which is to request a mapping update any
time there is an index metadata update. As index metadata updates can
occur for many reasons other than mapping updates, this leads to some
unnecessary requests and work in cross-cluster replication.
With this commit we implement a workaround for
https://bugs.openjdk.java.net/browse/JDK-8207200 which is a race
condition in the JVM that results in `IllegalArgumentException` to be
thrown in rare cases when we determine memory usage via `MemoryMXBean`.
As we do not want to fail requests in those cases we always return zero
memory usage.

When applying index metadata updates we run through the mappings
updating them if needed. Today if there is not an update to the default
mapper, we can lose the default mapping. This means that, for example,
if we apply a settings update to an index we will lose the default
mapper. This happens because we were not guarding updating the default
mapping with a check that the default mapping was updated in the
metadata update. When there is no update in the metadata update, we need
to continue to preserve the previous default mapping. This commit
achieves this by moving the updating of the default mapping under the
same guard that we use for updating the default mapping source. We add a
test that fails before putting the update under a guard and now passes
after moving the update under the guard.
This commit fixes a mappings update test. The test is broken in the
sense that it passes, but for the wrong reason. The test here is testing
that if we make a mapping update but do not commit that mapping update
then the mapper service still maintains the previous document
mapper. This was not the case long, long ago when a mapping update would
update the in-memory state before the cluster state update was
committed. This test was passing, but it was passing because the mapping
update was never even updated. It was never even updated because it was
encountering a null pointer exception. Of course the in-memory state is
not going to be updated in that case, we are simply going to end up with
a failed cluster state update. Fixing that leads to another issue which
is that the mapping source does not even parse so again we would, of
course, end up with the in-memory state not being modified. We fix these
issues, assert that the result cluster state task completed
successfully, and finally that the in-memory state was not updated since
we never committed the resulting cluster state.

This adds support for connecting to a remote cluster through
a tcp proxy. A remote cluster can configured with an additional
`search.remote.$clustername.proxy` setting. This proxy will be used
to connect to remote nodes for every node connection established.
We still try to sniff the remote clsuter and connect to nodes directly
through the proxy which has to support some kind of routing to these nodes.
Yet, this routing mechanism requires the handshake request to include some
kind of information where to route to which is not yet implemented. The effort
to use the hostname and an optional node attribute for routing is tracked
in #32517Closes#31840
If a shard was closed, we return null for SeqNoStats. Therefore the

We used to set `maxScore` to `0` within `TopDocs` in situations where there is really no score as the size was set to `0` and scores were not even tracked. In such scenarios, `Float.Nan` is more appropriate, which gets converted to `max_score: null` on the REST layer. That's also more consistent with lucene which set `maxScore` to `Float.Nan` when merging empty `TopDocs` (see `TopDocs#merge`).
In our Netty layer we have had to take extra precautions against Netty
catching throwables which prevents them from reaching the uncaught
exception handler. This code has taken on additional uses in NIO layer
and now in the scheduler engine because there are other components in
stack traces that could catch throwables and suppress them from reaching
the uncaught exception handler. This commit is a simple cleanup of the
iterative evolution of this code to refactor all uses into a single
method in ExceptionsHelper.
Today we can only have non-affix settings updated and consumed _together_.
Yet, there are use-cases where two affix settings depend on each other which
makes using the hard without consuming updates together. Unfortunately, there is
not straight forward way to have N settings updated together in a type-safe way
having 2 still serves a large portion of use-cases.
This change allows an engine to recover from its local translog up to
the given seqno. The extended API can be used in these use cases:
When a replica starts following a new primary, it resets its index to
the safe commit, then replays its local translog up to the current
global checkpoint (see #32867).
When a replica starts a peer-recovery, it can initialize the
start_sequence_number to the persisted global checkpoint instead of the
local checkpoint of the safe commit. A replica will then replay its
local translog up to that global checkpoint before accepting remote
translog from the primary. This change will increase the chance of
operation-based recovery. I will make this in a follow-up.

The maximum map count boostrap check can be a hindrance to users that do
not own the underlying platform on which they are executing
Elasticsearch. This is because addressing it requires tuning the kernel
and a platform provider might now allow this, especially on shared
infrastructure. However, this bootstrap check is not needed if mmapfs is
not in use. Today we do not have a way for the user to communicate that
they are not going to use mmapfs. This commit therefore adds a setting
that enables the user to disallow mmapfs. When mmapfs is disallowed, the
maximum map count bootstrap check is not enforced. Additionally, we
fallback to a different default index store and prevent the explicit use
of mmapfs for an index.
This change introduces a dedicated ConnectionManager for every RemoteClusterConnection
such that there is not state shared with the TransportService internal ConnectionManager.
All connections to a remote cluster are isolated from the TransportService but still uses
the TransportService and it's internal properties like the Transport, tracing and internal
listener actions on disconnects etc.
This allows a remote cluster connection to have a different lifecycle than a local cluster connection,
also local discovery code doesn't get notified if there is a disconnect on from a remote cluster and
each connection can use it's own dedicated connection profile which allows to have a reduced set of
connections per cluster without conflicting with the local cluster.

There are two problems with the scheduler engine today. Both relate to
listeners that throw.
The first problem is that any triggered listener that throws a plain old
exception will cause no additional listeners to be triggered for the
event, and will also cause the scheduler to never be invoked again. This
leads to lost events and is bad.
The second problem is that any triggered listener that throws an error
of the fatal kind will not lead to that error because caught by the
uncaught exception handler. This is because the triggered listener is
executed as a future task under a scheduled thread pool executor. A
throwable there goes caught by the JDK framework and set as the outcome
on the future task. Since we never inspect these tasks for their
outcomes, nor is there a good place to do this, we have to handle these
errors ourselves. To do this, we catch them and dispatch them to the
uncaught exception handler via a forked thread. This is similar to our
handling in Netty.

All Translog inner closes should happen after tragedy exception is set (#32674)
We faced with the nasty race condition. See #32526
InternalEngine.failOnTragic method has thrown AssertionError.
If you carefully look at if branches in this method, you will spot that its only possible, if either Lucene IndexWriterhas closed from inside or Translog, has closed from inside, but tragedy exception is not set.
For now, let us concentrate on the Translog class.
We found out that there are two methods in Translog - namely rollGeneration and trimOperations that are closing Translog in case of Exception without tragedy exception being set.
This commit fixes these 2 methods. To fix it, we pull tragedyException from TranslogWriter up-to Translog class, because in these 2 methods IndexWriter could be innocent, but still Translog needs to be closed. Also, tragedyException is wrapped with TragicExceptionHolder to reuse CAS/addSuppresed functionality in Translog and TranslogWriter.
Also to protect us in the future and make sure close method is never called from inside Translog special assertion examining stack trace is added. Since we're still targeting Java 8 for runtime - no StackWalker API is used in the implementation.
In the stack-trace checking method, we're considering inner caller not only Translog methods but Translog child classes methods as well. It does mean that Translog is meant for extending it, but it's needed to be able to test this method.

This is related to #32517. This commit passes the DiscoveryNode to the
initiateChannel method for different Transport implementation. This
will allow additional attributes (besides just the socket address) to be
used when opening channels.
Randomized test conditions that cause some shards to have no docs on them
failed due to test asserts that relied on a lazy initialization side effect
from the map script. After this fix:
- Test cases with the relevant init script are protected
- Test cases with the relevant combine or reduce scripts were already
protected, because the combine and reduce scripts safely handle this case.
This is a followup to #31886. After that commit the
TransportConnectionListener had to be propogated to both the
Transport and the ConnectionManager. This commit moves that listener
to completely live in the ConnectionManager. The request and response
related methods are moved to a TransportMessageListener. That listener
continues to live in the Transport class.

Currently, if geo context is represented by something other than
geo_point or an object with lat and lon fields, the parsing of it
as a geo context can result in ignoring the context altogether,
returning confusing errors such as number_format_exception or trying
to parse the number specifying as long-encoded hash code. It would also
fail if the geo_point was stored.
This commit makes the mapping parsing more strict and will fail during

testDocStats test is flaky and sometimes it's failing on jenkins and
failure is not reproducible locally. The reason for this failure is in
timing. If the number of deleted documents is greater than 33% of inserted
documents, Lucene will schedule segments to merge if TieredMergePolicy is
used (it's not the case for LogMergePolicy, but ES is only using
TieredMergePolicy). If this merge is performed before stats are
retrieved - we will get 0 for "deleted" counter.
So basically this counter could be either 0 or numOfDeletedDocs at this point,
but this is the too loose assertion and we decided to remove it at all.

We do not support passphrases on the secure settings storage (the

removes this support so that we are not limited in our future options,

This change cleans up some methods in the CharArrays class from x-pack, which
includes the unification of char[] to utf8 and utf8 to char[] conversions that
intentionally do not use strings. There was previously an implementation in
x-pack and in the reloading of secure settings. The method from the reloading
of secure settings was adopted as it handled more scenarios related to the
backing byte and char buffers that were used to perform the conversions. The
cleaned up class is moved into libs/core to allow it to be used by requests
that will be migrated to the high level rest client.

Fix global checkpoint listeners test
HLRC: adding machine learning open job (#32860)
[ML] Add log structure finder functionality (#32788)
INGEST: Add Configuration Except. Data to Metdata (#32322)
This commit fixes a global checkpoint listeners test wherein we were
expecting an executor to have been used even if there were no
listeners. This is silliness, so this commit adjusts the assertion to
verify that the executor never fires if there are no listeners, and
fires exactly once if there is one or more listeners.
This commit introduces the ability for global checkpoint listeners to be
registered at the shard level. These listeners are notified when the
global checkpoint is updated, and also when the shard closes. To
encapsulate these listeners, we introduce a shard-level component that
handles synchronization of notification and modifications to the
collection of listeners.
This is related to #31835. It moves the default connection profile into
the ConnectionManager class. The will allow us to have different
connection managers with different profiles.
This removes custom Response classes that extend `AcknowledgedResponse` and do nothing, these classes are not needed and we can directly use the non-abstract super-class instead.
While this appears to be a large PR, no code has actually changed, only class names have been changed and entire classes removed.
This commit adds a java time version of the existing rounding classes, which features the same test suite and a small test class to check if serialization works as expected.
Significance score doubles were being parsed as long. Existing tests did not catch this because SignificantLongTermsTests and SignificantStringTermsTests did not set the score. Fixed these and also added integration test.

Currently AbstractBuilderTestCase generates certain random values in its
`beforeTest()` method annotated with @Before only the first time that a test
method in the suite is run while initializing the serviceHolder that we use for
the rest of the test. This changes the values of subsequent random values
and has the effect that when running single methods from a test suite with
"-Dtests.method=*", the random values it sees are different from when the same
test method is run as part of the whole test suite. This makes it hard to use
the reproduction lines logged on failure.
This change runs the inialization of the serviceHolder and the randomization
connected to it using the test runners master seed, so reproduction by running
just one method is possible again.
Closes#32400
Processing bulk request goes item by item. Sometimes during processing, we need to stop execution and wait for a new mapping update to be processed by the node. This is currently achieved by throwing a `RetryOnPrimaryException`, which is caught higher up. When the exception is caught, we wait for the next cluster state to arrive and process the request again. Sadly this is a problem because all operations that were already done until the mapping change was required are applied again and get new sequence numbers. This in turn means that the previously issued sequence numbers are never replicated to the replicas. That causes the local checkpoint of those shards to be stuck and with it all the seq# based infrastructure.
This commit refactors how we deal with retries with the goal of removing `RetryOnPrimaryException` and `RetryOnReplicaException` (not done yet). It achieves so by introducing a class `BulkPrimaryExecutionContext` that is used the capture the execution state and allows continuing from where the execution stopped. The class also formalizes the steps each item has to go through:
1) A translation phase for updates
2) Execution phase (always index/delete)
3) Waiting for a mapping update to come in, if needed
4) Requires a retry (for updates and cases where the mapping are still not available after the put mapping call returns)
5) A finalization phase which allows updates to the index/delete result to an update result.
This adds a java time based date math parser class in order, which will replace the joda date based one in the future. For now the class also returns the date in milliseconds since the epoch.
Currently if a document cannot be indexed because it violates the defined
mapping for the index, a MapperException is thrown. In some cases it is
useful to expose the expected field type in the exception itself,
so that the user can react based on the error message. This change adds
the expected data type to the MapperException.
Closes#31502
Remove a few of the logger constructors that aren't widely used or
aren't used at all and deprecate a few more logger constructors in favor
of log4j2's `LogManager`.
A bug in the test suite prevented to properly check that all date
formatters printed the date the same way like joda time does.
This fixes the test and thus also a fair share of formats, that
now use the strict parser for printing.
We previously discussed moving the classes extending `AcknowledgedResponse` to
simply use `AcknowledgedResponse`, making the class non-abstract.
This moves the first class to do this, removing `WritePipelineResponse` in the
process.
If we like the way this looks, I will switch the remaining classes over to using
`AcknowledgedResponse`.

* Fixes suggestion generics
This solves a compile problem in Eclipse where Eclipse could not
resolve the generics for the options field in `PhraseSuggestion.Entry`.
But I think this is also a good change in general because
`PhraseSuggestion.Entry` is now declaring the specific `Option`
implementation it requires rather than `Suggest.Entry.Option` which is
more general and could lead to weird bugs. `CompletionSuggestion.Entry`
and `TermSuggestion.Entry` already declare the more specific class they
use so I think this was an oversight in `PhaseSuggestion.Entry`

Yet, it does not seem to be possible in practice for the cause to be null, hence we can clean that up and enforce the cause to be a non null value. This is best done by making `ShardOperationFailedException` an abstract class rather than an interface, which holds the basic member instance that all the subclasses have in common and can also enforce that cause, status and reason are non null.
