We changed the `action.auto_create_index` setting to be a dynamic cluster-level
setting in #20274 but today the reference manual indicates that it is still a
static node-level setting. This commit addresses this, and clarifies the
semantics of patterns that may both permit and forbid the creation of certain
indices.
Relates #7513
We have read and write aliases for the ML results indices. However,
the job still had methods that purported to reliably return the name
of the concrete results index being used by the job. After reindexing
prior to upgrade to 7.x this will be wrong, so the method has been
renamed and the comments made more explicit to say the returned index
name may not be the actual concrete index name for the lifetime of the
job. Additionally, the selection of indices when deleting the job
has been changed so that it works regardless of concrete index names.
All these changes are nice-to-have for 6.7 and 7.0, but will become
critical if we add rolling results indices in the 7.x release stream
as 6.7 and 7.0 nodes may have to operate in a mixed version cluster
that includes a version that can roll results indices.
The docs silently accept duplicate note markers (such as `<3>` here) but
formats them in an unexpected way. This change removes this duplication so that
the rendered documentation looks as intended.
* Changed `LuceneSnapshot` to throw an `OperationsMissingException` if the requested ops are missing.
* Changed the shard changes api to handle the `OperationsMissingException` and wrap the exception into `ResourceNotFound` exception and include metadata to indicate the requested range can no longer be retrieved.
* Changed `ShardFollowNodeTask` to handle this `ResourceNotFound` exception with the included metdata header.

From previous PRs, we've already added support for include_type_name to
the get mapping API. We had also taken an approach to the HLRC where the
server-side `GetMappingResponse#fromXContent` could only handle typeless
input.
This PR updates the HLRC for 'get mapping' to be in line with our new approach:
* Add a typeless 'get mappings' method to the Java HLRC, that accepts new
client-side request and response objects. This new response only handles
typeless mapping definitions.
* Switch the old version of `GetMappingResponse` back to expecting typed
mappings, and deprecate the corresponding method on the HLRC.
Finally, the PR also does some small, related clean-up around 'get field mappings'.
This commit introduces the `create_snapshot` cluster privilege and
the `snapshot_user` role.
This role is to be used by "cronable" tools that call the snapshot API
periodically without recurring to the `manage` cluster privilege. The
`create_snapshot` cluster privilege is much more limited compared to
the `manage` privilege.
The `snapshot_user` role grants the privileges to view the metadata of
all indices (including restricted ones, i.e. .security). It obviously grants the
create snapshot privilege but the repository has to be created using another
role. In addition, it grants the privileges to (only) GET repositories and
snapshots, but not create and delete them.
The role does not allow to create repositories. This distinction is important
because snapshotting equates to the `read` index privilege if the user has
control of the snapshot destination, but this is not the case in this instance,
because the role does not grant control over repository configuration.
There is a method invocation here spanning multiple lines. This commit
breaks it up into a line per parameter as this is friendlier to future
changes and diffs.
When adding a retention lease, we make a reference copy of the retention
leases under lock and then make a copy of that collection outside of the
lock. However, since we merely copied a reference to the retention
leases, after leaving a lock the underlying collection could change on
us. Rather, we want to copy these under lock. This commit adds a
dedicated method for doing this, asserts that we hold a lock when we use
this method, and changes adding a retention lease to use this method.
This commit was intended to be included with #37398 but was pushed to
the wrong branch.
This commit introduces retention lease syncing from the primary to its
replicas when a new retention lease is added. A follow-up commit will
add a background sync of the retention leases as well so that renewed
retention leases are synced to replicas.
Made the test tolerant to index upgrade being run
in between the old/mixed/upgraded portions. This
can occur because the rolling upgrade tests all
share the same indices.
Fixes#37763
The ML file structure finder has always reported both Joda
and Java time format strings. This change makes the Java time
format strings the ones that are incorporated into mappings
and ingest pipeline definitions.
The BWC syntax of prepending "8" to these formats is used.
This will need to be removed once Java time format strings
become the default in Elasticsearch.
This commit also removes direct imports of Joda classes in the
structure finder unit tests. Instead the core Joda BWC class
is used.
Previously, a hardcoded precision value of 4 was
used by these tests resulting in no approximation
errors. Now that the precision is between 1-12,
precision values of 1 and 2 result in potential
bucketing errors.
This commit adjusts the range to be 4-12.
Fixes#37892.
This commit fixes the distribution flavor passed to the docs tests to be
the same as the distribution. These two values are now in sync (either
oss or default) for the docs tests.
If the in_sync_allocations of index-1 or index-2 is changed, the
metadata version will be increased. This leads to the failure in
the metadata version checks. We need to relax them.
Closes#37820
* Refactored GeoHashGrid unit tests
This change allows other grid aggregations to reuse the same tests.
The change mostly just moves code to the base classes, trying to
keep changes to a bare minimum.
* rename createInternalGeoHashGridBucket to createInternalGeoGridBucket
* indentation
Replaces intermediate geo objects built by ShapeBuilders with
objects from the libs/geo hierarchy. This should allow us to build
all geo functionality around a single hierarchy.
Follow up for #35320
The /etc/elasticsearch directory is currently configured as a config
file with noreplace. However, the directory itself is not config, and
can lead to an entire /etc/elasticsearch.rpmsave directory in some
situations. This commit fixes the ospackage config to not specify those
file bits for the directory itself, but only the files underneath it.
The packaging tests currently have a test which installs elasticsearch,
removes it, modifies ownership of /etc/elasticsearch, and
reinstalls. It then checks that the /etc/elasticsearch directory has
ownership that the package expects. But the recursive change touches
files not owned by the package. In the past this worked because we did a
recursive ownership change within the package postinst. However, that
was recently removed, and thus this test no longer makes sense.
* Exit batch files explictly using ERRORLEVEL
This makes sure the exit code is preserved when calling the batch
files from different contexts other than DOS
Fixes#29582
This also fixes specific error codes being masked by an explict
exit /b 1
causing the useful exitcodes from ExitCodes to be lost.
* fix line breaks for calling cli to match the bash scripts
* indent size of bash files is 2, make sure editorconfig does the same for bat files
* update indenting to match bash files
* update elasticsearch-keystore.bat indenting
* Update elasticsearch-node.bat to exit outside of endlocal
The TransportUnfollowAction updates the index settings but does not
increase the settings version to reflect that change.
This issue has been caught while working on the replication of closed
indices (#33888). The IndexFollowingIT.testUnfollowIndex() started to
fail and this specific assertion tripped. It does not happen on master
branch today because index metadata for closed indices are never
updated in IndexService instances, but this is something that is going
to change with the replication of closed indices.
The unlucky timing can cause this test to fail when the indexing is triggered from `maybeTriggerAsyncJob`. As this is asynchronous, in can finish quicker then the test stepping over to next assertion
The introduced barrier solves the problem

Due to floating point error, it was possible for variances to become negative which should never happen. This bugfix sets variance to zero if it becomes negative as a result of fp error.
This test indexes an unlimited number of documents, this commit
reduces this number to 25K and also tracks exact number of hits
when counting the docs.
* Remove empty statements
There are a couple of instances of undocumented empty statements all across the
code base. While they are mostly harmless, they make the code hard to read and
are potentially error-prone. Removing most of these instances and marking blocks
that look empty by intention as such.
* Change test, slightly more verbose but less confusing
Node started with node.data=false and node.master=false can no longer
start if they have index metadata. This avoids resurrecting old indexes
into the cluster and ensures metadata is cleaned out before
re-purposing a node that was previously master or data node.
Issue #27073
When upgrading from 5.4 to 5.5 to 6.7 (inclusive) it was
necessary to ensure there was a mapping for type "doc" on
the ML state index before opening a job. This was because
5.4 created a multi-type ML state index.
In version 7.x we can be sure that any such 5.4 index is no
longer in use. It would have had to be reindexed into the
6.x index format prior to the upgrade to version 7.x.
This changes adds the support to handle `nested` fields in the `composite`
aggregation. A `nested` aggregation can be used as parent of a `composite`
aggregation in order to target `nested` fields in the `sources`.
Closes#28611
The ingest date processor is currently only able to parse joda formats.
However it is not using the existing elasticsearch classes but access
joda directly. This means that our existing BWC layer does not notify
the user about deprecated formats. This commit switches to use the
exising Elasticsearch Joda methods to acquire a date format, that
includes the BWC check and the ability to parse java 8 dates.
The date parsing in ingest has also another extra feature, that the
fallback year, when a date format without a year is used, is the current
year, and not 1970 like usual. This is currently not properly supported
in the DateFormatter class. As this is the only case for this feature
and java time can take care of this using the toZonedDateTime() method,
a workaround just for the joda time parser has been created, that can be
removed soon again from 7.0.
This commit changes the default for the `track_total_hits` option of the search request
to `10,000`. This means that by default search requests will accurately track the total hit count
up to `10,000` documents, requests that match more than this value will set the `"total.relation"`
to `"gte"` (e.g. greater than or equals) and the `"total.value"` to `10,000` in the search response.
Scroll queries are not impacted, they will continue to count the total hits accurately.
The default is set back to `true` (accurate hit count) if `rest_total_hits_as_int` is set in the search request.
I choose `10,000` as the default because that's also the number we use to limit pagination. This means that users will be able to know how far they can jump (up to 10,000) even if the total number of hits is not accurate.
