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.

We disabled the Javadoc task on JDK 10 due to an apparent bug in Javadoc
generation on JDK 10. However, the client JAR task sets up its own
Javadoc task for client JARs (because it merely copies the non-client
Javadoc JAR). This commit diables that task too, since the Javadocs for
the non-client JAR will not exist.

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.

There appears to be a bug in JDK 10 for generating Javadocs with some
nested anonymous classes. This commit disables these on JDK 10 until the
upstream issue is resolved.

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

* Splits nio project into two for eclipse build only
https://github.com/elastic/elasticsearch/pull/27801 introduced a new gradle project `:libs:elasticsearch-nio` which creates cyclical project dependencies when importingthe projects into Eclipse.
This change applies the same trick as we have for the core project where, and building for Eclipse, splits the `:libs:elasticsearch-nio` project into `:libs:elasticsearch-nio` which points to `src/main` and `:libs:elasticsearch-nio-tests` which points to `src/test`. This prevents cyclical project dependencies in Eclipse arising from the fact that eclipse does not separate compile/runtime dependencies from test dependencies.
* Removes integTest bits since there are none
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.
These templates were generated with 5.0. We need those generated with 6.0 since
we do not guarantee compatibility with previous versions of the template anyway.
I removed the winlogbeat template which is a bit harder to generate as it requires
Windows, since we do not aim to be exhaustive.
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.
JDK 10 has gone fully-modular. This means that:
- when targeting JDK 8 with a JDK 10 compiler, we have to use the full
profile
- when targeting JDK 10 with a JDK 10 compiler, we have to use
-add-modules java.base
Today we only target JDK 8 (our minimum compatibility version) so we
need to change the compiler flags conditional on using a JDK 10
compiler. This commit does that.

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.

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.
TestZenDiscovery is used to allow discovery based on in memory structures. This isn't a relevant for the cloud providers tests (but isn't a problem at the moment either)
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.
The last operation executed in IndicesClientDocumentationIT.testCreate()
is an asynchronous index creation. Because nothing waits for its
completion, on slow machines the index can sometimes be created after
the testCreate() test is finished, and it can fail the following test.
Closes#27754
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.
Closes#27841
Elasticsearch offers a number of http requests that can take a while to
execute. In #27713 we introduced an http read timeout that defaulted to
30 seconds. This means that if no reads happened for 30 seconds (even
after a request is received), the connection would be closed due to
timeout.
This commit disables the read timeout by default to allow us to evaluate
the impact of read timeouts and to avoid introducing distruptive
behavior.
Currently, method corruptTranslogFiles corrupts some translog files
whose translog_gen are at least the min_required_translog_gen from the
translog checkpoint. However this condition is not enough for
recoverFromTranslog to be always failed. If we corrupt only translog
operations from only translog files whose translog_gen are smaller than
the min_translog_gen of a recovering index commit, recoverFromTranslog
will be ok as we won't read translog operations from those files.
This commit makes sure corruptTranslogFiles to corrupt some translog
files that will be used in recoverFromTranslog.
Closes#27538
When the first parameter of `ESTestCase#randomValueOtherThan` is `null`
then run the supplier until it returns non-`null`. Previously,
`randomValueOtherThan` just ran the supplier one time which was
confusing.
Unexpectedly, it looks like not tests rely on the original `null`
handling.
