These strings are quite long individually and will be repeated
potentially up to the number of snapshots in the repository times.
Since these make up more than half of the size of the repository metadata
and are likely the same for all snapshots the savings from deduplicating them
can make up for more than half the size of `RepositoryData` easily in most real-world
cases.
Store stats can be `null` if e.g. the shard was already closed
when the stats where retrieved. Don't record those shards in the
sizes map to fix an NPE in this case.
When n=0 in TranslogTests.testTotalTests we never update earliestLastModifiedAge so it fails comparison with default value of total.getEarliestLastModifiedAge() which is 0.
In this change we always check this special case and then select n>0

In the refactoring of TextFieldMapper, we lost the ability to define
a default search or search_quote analyzer in index settings. This
commit restores that ability, and adds some more comprehensive
testing.
Fixes#65434
In certain situations, such as when configured in FIPS 140 mode,
the Java security provider in use might throw a subclass of
java.lang.Error. We currently do not catch these and as a result
the JVM exits, shutting down elasticsearch.
This commit attempts to address this by catching subclasses of Error
that might be thrown for instance when a PBKDF2 implementation
is used from a Security Provider in FIPS 140 mode, with the password
input being less than 14 bytes (112 bits).
- In our PBKDF2 family of hashers, we catch the Error and
throw an ElasticsearchException while creating or verifying the
hash. We throw on verification instead of simply returning false
on purpose so that the message bubbles up and the cause becomes
obvious (otherwise it would be indistinguishable from a wrong
password).
- In KeyStoreWrapper, we catch the Error in order to wrap and re-throw
a GeneralSecurityException with a helpful message. This can happen when
using any of the keystore CLI commands, when the node starts or when we
attempt to reload secure settings.
- In the `elasticsearch-users` tool, we catch the ElasticsearchException that
the Hasher class re-throws and throw an appropriate UserException.
Tests are missing because it's not trivial to set CI in fips approved mode
right now, and thus any tests would need to be muted. There is a parallel
effort in #64024 to enable that and tests will be added in a followup.
KeyStoreAwareCommand attempted to deduce whether an error occurred
because of a wrong password by checking the cause of the
SecurityException that KeyStoreWrapper.decrypt() throws. Checking
for AEADBadTagException was wrong becase that exception could be
(and usually is) wrapped in an IOException. Furthermore, since we
are doing the check already in KeyStoreWrapper, we can just return
the message of the SecurityException to the user directly, as we do
in other places.
A bug was introduced in 7.10 that causes explicit `null` values to be indexed in the _field_names
field. This change fixes this bug for newly ingested data but `null` values ingested with 7.10 will
continue to match `exists` query so a reindex is required.
Fixes#65306
This change fixes the equals and hashCode methods of the custom FieldValuesSource
that is used internally to extract the value from a doc value field.
Using the field data instance to check equality prevented the query to be cached in
previous versions. Switching to the field name should make the query eligible for
caching again.
Watcher has a search template that stores indices options to be used as
part of a search during watch execution, but this was not updated to be
aware of hidden indices and the `hidden` expand_wildcards option. This
change makes use of the `IndicesOptions#toXContent` method in Watcher,
which already handles the new value. Additionally, the XContent parsing
is moved to the IndicesOptions class so that we will be less likely to
miss updating this in the future.

In aa1ea96b8698aa12bed1c4e8d704882a2a639791 I made all
`testReduceRandom` tests for aggs mimick production more precisely.
More precisely, they pick the correct "lead" result when performing
partial reduction. This is great, but, sadly, some tests assumed that we
always reduced against the "first" aggregator. This fixes those tests.
Closes#65163
This commit updates the IndexAbstractionResolver so that hidden indices
are properly resolved when date math is in use and when we are checking
if the index is visible.

- Add LongRareTerms and StringRareTerms to the DefaultNamedXContents,
ensure that the response of RareTerms aggregation can be parsed
correctly.
- Add testSearchWithRareTermsAgg method to test the response of
RareTerms aggregation can be parsed correctly.
- Add some test code to ensure the AggregationsTests can execute
successfully.

We were correctly dealing with boosts that had an effect, but mappers
that had a silently accepted but ignored boost parameter were throwing
an error instead of continuing to ignore the boost but emitting a
warning.
Fixes#64982
Currently a rejected execution exception can be swallowed when async
actions return during transport bulk actions. This includes scenarios
where we went async to perform ingest pipelines or index creation. This
commit resolves the issue by propagating a rejected exception.
Node roles vary by version, and new roles are suppressed for BWC. This
means we can receive a join from a node that's already in the cluster
but with a different set of roles: the node didn't change roles, but the
cluster state came via an older master. This commit ensures that we
properly process a join from such a node to ensure that the roles are
correct.
Closes#62840
This change fixes a bug introduced in #61779 that uses a compound order to
compare buckets when merging. The bug is triggered when the compound order
uses a primary sort ordered by key (asc or desc).
This commit ensures that we always extract the primary sort when comparing keys
during merging.
The PR is marked as no-issue since the bug has not been released in any official version.
This commit internalizes whether or not a role represents the ability to
contain data. In the future, this will let us remove the compatibility
role notion.
Now that we're consistently using `cat_match` to filter which shards we
run on we can get this confusing case:
1. You have a search with, say, a range and a sub-agg.
2. That search has a query that `can_match` can recognize will match no
docs. On *any* shard.
3. So we dutifully run it on a single shard so it can produce the
"empty" aggs.
4. The shard we pick happens to not have the target of the range mapped.
5. This kicks in the special range aggregator that doesn't collect any
documents.
6. Before this commit, that range aggregator *also* never produced any
sub-aggs.
So, without this change, it was quite possible for a search that
happened to match no documents to "throw away" the sub-aggs of a range
and a few other aggs.
We've had this problem for a long, long time but it is more confusing
now because `can_match` is really kicking in and causing us to see cases
where it looks like you are targeting a lot of shards but you really are
only targeting a couple. It used to be that to get the "no sub-aggs"
behavior you had to explicitly target only shards that didn't map the
target field of the `range` agg. And, like, in that case it isn't too
bad because you targeted a sort of degenerate shard. But now that
`can_match` is doing its thing you can end up with the confusing steps
above. It took me several hours to track down what what happening I know
how the individual pieces of all of this works. It took four hours to
figure out how they fit together in this case....
Anyway! This replaces all the aggregator implementations that throw out
the sub-aggregators with ones that keep them. I think this'll be less
confusing in the future.
Closes#64142
This commit adds logging to indicate whether or not we are using the
bundled JDK. We distinguish between using a distribution that bundles
the JDK versus using a distribution that does not bundle the JDK.
In 7.x we can't just by default generate this setting as it might not be
supported by data nodes that are assigned shards for an older version in mixed version
clusters.
Closes#64152
This commit fixes an issue with the detection on macOS for whether or
not the bundled JDK is being used. The logic between macOS and non-macOS
is different because the JDK has a different directory structure on
macOS versus non-macOS. However, due to notarization issues, we changed
the top-level directory from jdk to jdk.app, yet never updated this
detection logic to account for that.
Ideally, we would have a packaging test that asserts that we have the
behavior here correct, and it maintains over time. Alas, we do not
currently have packaging tests on macOS.
With this change, we will always return the same point in time in a
search response as its input until we implement the retry mechanism
for the point in times.
The formatting of the global bottom value does not take the resolution of the provided
numeric_type into account. This change fixes this bug by providing the resolution
directly in the doc value format if the numeric_type is provided as `date_nanos`.
Closes#63719
We must not remove the snapshot from the initializing set
in the `timeout` getter. This was a plain oversight/mistake
and went unnoticed. It can lead to the removal of a valid
snapshot clone from the cluster state in rare circumstances
(e.g. when a node concurrently joins the cluster or a routing
change happens as it did in the linked test failure).
