There were two subtle bugs here from backporting #56911 to 7.x.
1. We passed `null` for the `shards` map which isn't nullable any longer
when creating `SnapshotsInProgress.Entry`, fixed by just passing an empty map
like the `null` handling did in the past.
2. The removal of a failed `INIT` state snapshot from the cluster state tried
removing it from the finalization loop (the set of repository names that are
currently finalizing). This will trip an assertion since the snapshot failed
before its repository was put into the set. I made the logic ignore the set
in case we remove a failed `INIT` state snapshot to restore the old logic to
exactly as it was before the concurrent snapshots backport to be on the safe
side here.
Also, added tests that explicitly call the old code paths because as can be seen
from initially missing this, the BwC tests will only run in the configuration new
version master, old version nodes ever so often and having a deterministic test
for the old state machine seems the safest bet here.
Closes#59986
If shard level results are incomplete in the data streams stats call, it is possible to get inaccurate
counts of the number of backing indices, despite this data being accurate and available in the
cluster state.
For ingest node processors a per processor description
was recently added. This commit displays that description
in the verbose output of the pipeline simulation.
related #57906
In #54716 I removed pipeline aggregators from the aggregation result
tree and caused us to read them from the request. This saves a bunch of
round trip bytes, which is neat. But there was a bug in the backwards
compatibility logic. You see, we still have to give the pipeline
aggregations to nodes older than 7.8 over the wire because that is how
they know what pipelines to run. They have the pipelines in the request
but they don't read them. They use the ones in the response tree.
Anyway, we had a bug where we were never sending pipelines defined two
levels down. So while you are upgrading the pipeline wouldn't run.
Sometimes. If the data node of the "first" result was post-7.8 and the
coordinating node was pre-7.8.
This fixes the bug.
This PR removes the expand_wildcards and forbid_closed_indices parameters from the Data
Streams Stats REST endpoint. These options are required for broadcast requests, but are not
needed for anything in terms of resolving data streams. Instead, we just set a default set of
IndicesOptions on the transport request.
Adds a new `my-index-00001` REST test for docs snippets.
This test can serve as a lightweight replacement for
our existing `twitter` REST tests.
The new dataset is:
* Based on Apache logs, which is better aligned with Elastic use cases
* Compliant with ECS
* Similar to the existing `twitter` data set, containing the same field data types
* Lightweight, which should keep existing test runtimes roughly the same
Also updates the search API reference docs to use the new test.
This test failed by hitting the 10s default busy assert timeout.
Given how involved the retention run is (multiple disk reads, CS updates etc.)
we should have a higher timeout here.
Also, removed the pointless delete call for the snapshot that we just asserted is gone,
at the end of the test.
Closes#59956
Today the `InternalClusterInfoService` uses the
`LocalNodeMasterListener` interface to start/stop its operations. Since
the `onMaster` and `offMaster` methods are called on the `MANAGEMENT`
threadpool, there's no guarantee that they run in the correct sequence,
which could result in an elected master failing to regularly update the
cluster info.
Since this service is also a `ClusterStateListener` we may as well drop
the usage of the `LocalNodeMasterListener` interface and simply update
the status of the local node on the applier thread in `clusterChanged`
to ensure consistency.
Additionally, today the `InternalClusterInfoService` uses a simple flag
to track whether the local node is the elected master or not. If the
node stops being the master and then starts again within a few seconds
then the scheduled updates from the old mastership might carry on
running in addition to the ones for the new mastership.
This commit addresses that by tracking the identity of the scheduled
update job and creating a new job for each mastership.
This commit allows customizing the word delimiter token filters to skip processing
tokens tagged as keyword through the `ignore_keywords` flag Lucene's
WordDelimiterGraphFilter already exposes.
Fix for #59491
The TypeParser implementations of all ParametrizedFieldMapper descendant classes are
essentially the same - stateless, requiring the construction of a Builder object, and calling
parse on it before returning it. We can make this easier (and less error-prone) to
implement by wrapping the logic up into a final class, which takes a function to produce
the Builder from a name and parser context.
We never used the `IndexSettings` parameter and we only used the
`MappedFieldType` parameter to get the name of the field which we
already know everywhere where we build the `IFD.Builder`. This allows us
to drop a fair bit of ceremony from a couple of tests.
ParametrizedFieldMapper overrides `toXContent` from `FieldMapper`, yet it could override `doXContentBody` and rely on the `toXContent` from the base class. Additionally, this allows to make `doXContentBody` final. Also, toXContent is still overridden only to make it final.
With uuid named segment data blobs there is no reason to ensure no overwrites are happening
for these blobs when writing. On the contrary, at least on Azure this check can conflict with
the SDK's retrying and cause upload failures randomly.
* Simplify test error reporting
- avoid using extra plugin
- avoid extra task listener (should be avoided related to #57918 )
- keep all logic in the listener
Refactored `CheckSumBlobStoreFormat` so it can more easily be reused in
other functionality (i.e. upcoming repair logic).
Simplified away constant `failIfAlreadyExists` parameter and removed the atomic
write method and its tests.
The atomic write method was only used in a single spot and that spot has now been adjusted to
work the same way writing root level metadata works.
Follow up to #59606 using some of the new infrastructure and making similar cleanups (and due to at times better handling of size hints and empty collections also optimizations in the stream utility methods this also means speedups) in various spots in the core codebase.
Previously we constructed a GeometryFormat object and delegated point parsing to
it. This wasn't a good fit conceptually because each GeometryFormat instance
didn't represent a distinct point format.
Before it was missing from the list. This PR also renames the 'geo data types'
section to 'spatial data types' and consolidates the geo and cartesian types
into that section.
We use -y to automate apt install commands within vagrant provisioning.
However, this is sometimes insufficient, for example when a gpg
signature signing the package expires. This commit adds the extra
--force-yes flag, to tell apt-get we really mean business.

This PR further reduces the memory footprint of the
testGeoHashGridCircuitBreaker test such that only
0.26% of the randomized runs result in memory usage of between
500kb-1mb. where most of that those that are in that range
produce ~650kb of usage. Before, 3% of the runs would use
> 50mb of memory resulting in OOMs in CI
Closes#59853.
The clock resolution for this API is our default 200ms. It is unlikely but
possible that a shard snapshot starts and ends on separate clock ticks and that breaks the test.
Just allowing any value here seems fine to me (seems we can't match for integer specifically).
This change fixes two possible race conditions in SLM related to
how local master changes and cluster state events are observed. When
implementing the `LocalNodeMasterListener` interface, it is only
recommended to execute on a separate threadpool if the operations are
heavy and would block the cluster state thread. SLM specified that the
listeners should run in the Snapshot thread pool, but the operations
in the listener were lightweight. This had the side effect of causing
master changes to be delayed if the Snapshot threads were all busy and
could also potentially cause the `onMaster` and `offMaster` calls to
race if both were queued and then executed concurrently. Additionally,
the `SnapshotLifecycleService` is also a `ClusterStateListener` and
there is currently no order of operations guarantee between
`LocalNodeMasterListeners` and `ClusterStateListeners` so this could
lead to incorrect behavior.
The resolution for these two issues is that the
SnapshotRetentionService now specifies the `SAME` executor for its
implementation of the `LocalNodeMasterListener` interface. The
`SnapshotLifecycleService` is no longer a `LocalNodeMasterListener` and
instead tracks local master changes in its `ClusterStateListner`.
Backport of #59801
This replaces that data structure that we use to resolve bucket ids in
bucketing aggs that are inside other bucketing aggs. This replaces the
"legoed together" data structure with a purpose built `LongLongHash`
with semantics similar to `LongHash`, except that it has two `long`s
as keys instead of one.
The microbenchmarks show a fairly substantial performance gain on the
hot path, around 30%. Rally's higher level benchmarks show anywhere
from 0 to 7% speed improvements. Not as much as I'd hoped, but nothing
to sneeze at. And, after all, we all allocating slightly less data per
owningBucketOrd, which is always nice.
Today `GET _nodes/stats/fs` includes `{least,most}_usage_estimate`
fields for some nodes. These fields have rather strange semantics. They
are only reported on the elected master and on nodes that have been the
elected master since they were last restarted; when a node stops being
the elected master these stats remain in place but we stop updating them
so they may become arbitrarily stale.
This means that these statistics are pretty meaningless and impossible
to use correctly. Even if they were kept up to date they're never
reported for data-only nodes anyway, despite the fact that data nodes
are the ones where we care most about disk usage. The information needed
to compute the path with the least/most available space is already
provided in the rest the stats output, so we can treat the inclusion of
these stats as a bug and fix it by simply removing them in this commit.
Since these stats were always optional and mostly omitted (for opaque
reasons) this is not considered a breaking change.
