Today we do not consider trimAboveSeqNo when calculating the translog
generation of an index commit. If there is no new indexing after the
primary promotion, then we won't be able to clean up the translog.
Backport of #49612.
The current Docker entrypoint script picks up environment variables and
translates them into -E command line arguments. However, since any tool
executes via `docker exec` doesn't run the entrypoint, it results in
a poorer user experience.
Therefore, refactor the env var handling so that the -E options are
generated in `elasticsearch-env`. These have to be appended to any
existing command arguments, since some CLI tools have subcommands and
-E arguments must come after the subcommand.
Also extract the support for `_FILE` env vars into a separate script, so
that it can be called from more than once place (the behaviour is
idempotent).
Finally, add noop -E handling to CronEvalTool for parity, and support
`-E` in MultiCommand before subcommands.
With #45689 making it so that index metadata is written
after all shards have been snapshotted we can't delete indices
that are part of the upcoming snapshot finalization any longer
and it is not sufficient to check if all shards of an index have been
snapshotted before deciding that it is safe to delete it.
This change forbids deleting any index that is in the process of being
snapshot to avoid issues during snapshot finalization.
Relates #50200 (doesn't fully fix yet because we're not fixing the `partial=true`
snapshot case here
* Remove BlobContainer Tests against Mocks
Removing all these weird mocks as asked for by #30424.
All these tests are now part of real repository ITs and otherwise left unchanged if they had
independent tests that didn't call the `createBlobStore` method previously.
The HDFS tests also get added coverage as a side-effect because they did not have an implementation
of the abstract repository ITs.
Closes#30424
Lucene 8.4 added support for "CONTAINS", therefore in this commit those
changes are integrated in Elasticsearch. This commit contains as well a
bug fix when querying with a geometry collection with "DISJOINT" relation.
Since 7.4, we switch from translog to Lucene as the source of history
for peer recoveries. However, we reduce the likelihood of
operation-based recoveries when performing a full cluster restart from
pre-7.4 because existing copies do not have PPRL.
To remedy this issue, we fallback using translog in peer recoveries if
the recovering replica does not have a peer recovery retention lease,
and the replication group hasn't fully migrated to PRRL.
Relates #45136
Today we do not use retention leases in peer recovery for closed indices
because we can't sync retention leases on closed indices. This change
allows that ability and adjusts peer recovery to use retention leases
for all indices with soft-deletes enabled.

A recent change around date parsing (#46675) made it stricter, so we should now also
catch DateTimeExceptions in DateFieldMapper and ignore those when the
`ignore_malformed` option is set.
Closes#50081
When decoupling the pipeline reduction from regular agg reduction,
MultiBucket aggs were modified to reduce their bucket's pipeline
aggs first before reducing the sibling aggs. This modification
was missed on SingleBucket aggs, meaning any SingleBucket would
fail to reduce any pipeline sub-aggs
* Remove Unused Single Delete in BlobStoreRepository
There are no more production uses of the non-bulk delete or the delete that throws
on missing so this commit removes both these methods.
Only the bulk delete logic remains. Where the bulk delete was derived from single deletes,
the single delete code was inlined into the bulk delete method.
Where single delete was used in tests it was replaced by bulk deleting.
* Better Logging GCS Blobstore Mock
Two things:
1. We should just throw a descriptive assertion error and figure out why we're not reading a multi-part instead of
returning a `400` and failing the tests that way here since we can't reproduce these 400s locally.
2. We were missing logging the exception on a cleanup delete failure that coincides with the `400` issue in tests.
Relates #49429
This commit ensures deseriable a GetResult from StreamInput does not
leave metaFields and documentFields null. This could cause an NPE in
situations where upsert response for a document that did not exist is
passed back to a node that forwarded the upsert request.
closes#48215
Currently we do not know the size of the transport header (map of
request response headers, features array, and action name). This means
that we must read the entire transport message to dependably act on the
headers. This commit adds an int indicating the size of the transport
headers. With this addition we can act upon the headers prior to reading
the entire message.
Adjusts the subclasses of `TransportMasterNodeAction` to use their own loggers
instead of the one for the base class.
Relates #50056.
Partial backport of #46431 to 7.x.
Removes a reference to shadow replicas from the cat shards API docs
and a comment in cluster/routing/UnassignedInfo.java.
Shadow replicas were removed with #23906.
* Improve Snapshot Finalization Ex. Handling
Like in #49989 we can get into a situation where the setting of
the repository generation (during snapshot finalization) in the cluster
state fails due to master failing over.
In this case we should not try to execute the next cluster state update
that will remove the snapshot from the cluster state.
Closes#49989
The elasticsearch-node tools allow manipulating the on-disk cluster state. The tool is currently
unaware of plugins and will therefore drop custom metadata from the cluster state once the
state is written out again (as it skips over the custom metadata that it can't read). This commit
preserves unknown customs when editing on-disk metadata through the elasticsearch-node
command-line tools.
Today settings can declare dependencies on another setting. This
declaration is implemented so that if the declared setting is not set
when the declaring setting is, settings validation fails. Yet, in some
cases we want not only that the setting is set, but that it also has a
specific value. For example, with the monitoring exporter settings, if
xpack.monitoring.exporters.my_exporter.host is set, we not only want
that xpack.monitoring.exporters.my_exporter.type is set, but that it is
also set to local. This commit extends the settings infrastructure so
that this declaration is possible. The use of this in the monitoring
exporter settings will be implemented in a follow-up.
* Cleanup Old index-N Blobs in Repository Cleanup
Repository cleanup didn't deal with old index-N, this change adds
cleaning up all old index-N found in the repository.
Step on the road to #49060.
This commit adds the logic to keep track of a repository's generation
across repository operations. See changes to package level Javadoc for the concrete changes in the distributed state machine.
It updates the write side of new repository generations to be fully consistent via the cluster state. With this change, no `index-N` will be overwritten for the same repository ever. So eventual consistency issues around conflicting updates to the same `index-N` are not a possibility any longer.
With this change the read side will still use listing of repository contents instead of relying solely on the cluster state contents.
The logic for that will be introduced in #49060. This retains the ability to externally delete the contents of a repository and continue using it afterwards for the time being. In #49060 the use of listing to determine the repository generation will be removed in all cases (except for full-cluster restart) as the last step in this effort.
The fake translog corruption in the test sometimes generates invalid translog files where some
assertions do not hold (e.g. minSeqNo <= maxSeqNo or minTranslogGen <= translogGen)
Closes#49909
Makes sure that CCR also properly works with _source disabled.
Changes one exception in LuceneChangesSnapshot as the case of missing _recovery_source
because of a missing lease was not properly properly bubbled up to CCR (testIndexFallBehind
was failing).
If we have a nested `AbstractRunnable` inside of `TimedRunnable`
it's executed twice on `run` (once when its own `run` method is invoked and once when
the `onAfter` in the `TimedRunnable` is executed).
Simply removing the `onAfter` override in `TimedRunnable` makes sure that the `onAfter`
is only called once by the `run` on the nested `AbstractRunnable` itself.
Same was done for `onFailure` as it was double-triggering as well on exceptions in the inner `onFailure`.
In order to cache script results in the query shard cache, we need to
check if scripts are deterministic. This change adds a default method
to the script factories, `isResultDeterministic() -> false` which is
used by the `QueryShardContext`.
Script results were never cached and that does not change here. Future
changes will implement this method based on whether the results of the
scripts are deterministic or not and therefore cacheable.

**Backport**
Our docs specifically mention that CBOR is supported when ingesting attachments. However this is not tested anywhere.
This adds a test, that uses specifically CBOR format in its IndexRequest and another one that behaves like CBOR in the ingest attachment unit tests.
Historically only two things happened in the final reduction:
empty buckets were filled, and pipeline aggs were reduced (since it
was the final reduction, this was safe). Usage of the final reduction
is growing however. Auto-date-histo might need to perform
many reductions on final-reduce to merge down buckets, CCS
may need to side-step the final reduction if sending to a
different cluster, etc
Having pipelines generate their output in the final reduce was
convenient, but is becoming increasingly difficult to manage
as the rest of the agg framework advances.
This commit decouples pipeline aggs from the final reduction by
introducing a new "top level" reduce, which should be called
at the beginning of the reduce cycle (e.g. from the SearchPhaseController).
This will only reduce pipeline aggs on the final reduce after
the non-pipeline agg tree has been fully reduced.
By separating pipeline reduction into their own set of methods,
aggregations are free to use the final reduction for whatever
purpose without worrying about generating pipeline results
which are non-reducible
This is related to #49067. As part of this work a new sniff number of
node connections setting, a simple addresses setting, and a simple
number of sockets setting have been added. This commit ensures that
these settings are properly hooked up to support dynamic updates.
The list used by the search progress listener can be nullified
by another thread that reports a query result. This change replaces
the usage of this list with a new array that is synchronously modified.
Closes#49778
Adds `GET /_script_language` to support Kibana dynamic scripting
language selection.
Response contains whether `inline` and/or `stored` scripts are
enabled as determined by the `script.allowed_types` settings.
For each scripting language registered, such as `painless`,
`expression`, `mustache` or custom, available contexts for the language
are included as determined by the `script.allowed_contexts` setting.
Response format:
```
{
"types_allowed": [
"inline",
"stored"
],
"language_contexts": [
{
"language": "expression",
"contexts": [
"aggregation_selector",
"aggs"
...
]
},
{
"language": "painless",
"contexts": [
"aggregation_selector",
"aggs",
"aggs_combine",

not adjust testCacheability(), which how fails occasionally when given a random
interval source containing a script. This commit overrides testCacheability() to
explicitly sources with and without script filters.
Fixes#49821
By default, AbstractQueryTestCase only changes name and boost in its mutateInstance
method, used when checking equals and hashcode implementations. This commit adds
a mutateInstance method to InveralQueryBuilderTests that will check hashcode and
equality when the field or intervals source are changed.
By default the unified highlighter splits the input into passages using
a sentence break iterator. However we don't check if the field is tokenized
or not so `keyword` field also applies the break iterator even though they can
only match on the entire content. This means that by default we'll split the
content of a `keyword` field on sentence break if the requested number of fragments
is set to a value different than 0 (default to 5). This commit changes this behavior
to ignore the break iterator on non-tokenized fields (keyword) in order to always
highlight the entire values. The number of requested fragments control the number of
matched values are returned but the boundary_scanner_type is now ignored.
Note that this is the behavior in 6x but some refactoring of the Lucene's highlighter
exposed this bug in Elasticsearch 7x.
There is a possible NPE in IntervalFilter xcontent serialization when scripts are
used, and `equals` and `hashCode` are also incorrectly implemented for script
filters. This commit fixes both.
* Copying the request is not necessary here. We can simply release it once the response has been generated and a lot of `Unpooled` allocations that way
* Relates #32228
* I think the issue that preventet that PR that PR from being merged was solved by #39634 that moved the bulk index marker search to ByteBuf bulk access so the composite buffer shouldn't require many additional bounds checks (I'd argue the bounds checks we add, we save when copying the composite buffer)
* I couldn't neccessarily reproduce much of a speedup from this change, but I could reproduce a very measureable reduction in GC time with e.g. Rally's PMC (4g heap node and bulk requests of size 5k saw a reduction in young GC time by ~10% for me)
This commit fixes a number of issues with data replication:
- Local and global checkpoints are not updated after the new operations have been fsynced, but
might capture a state before the fsync. The reason why this probably went undetected for so
long is that AsyncIOProcessor is synchronous if you index one item at a time, and hence working
as intended unless you have a high enough level of concurrent indexing. As we rely in other
places on the assumption that we have an up-to-date local checkpoint in case of synchronous
translog durability, there's a risk for the local and global checkpoints not to be up-to-date after
replication completes, and that this won't be corrected by the periodic global checkpoint sync.
- AsyncIOProcessor also has another "bad" side effect here: if you index one bulk at a time, the
bulk is always first fsynced on the primary before being sent to the replica. Further, if one thread
is tasked by AsyncIOProcessor to drain the processing queue and fsync, other threads can
easily pile more bulk requests on top of that thread. Things are not very fair here, and the thread
might continue doing a lot more fsyncs before returning (as the other threads pile more and
more on top), which blocks it from returning as a replication request (e.g. if this thread is on the
primary, it blocks the replication requests to the replicas from going out, and delaying
checkpoint advancement).
This commit fixes all these issues, and also simplifies the code that coordinates all the after
write actions.
