In the long run we want to move all of startup to a Java program. This
will simplify our startup scripts and make maintenance of startup less
dependent on the underlying platform that we run on. This commit moves
the creation of the temporary directory off of system-dependent commands
and onto a simple Java program.
`PreferHasAttributeNodeSelector` works like exactly like
`HasAttributeNodeSelector` but if not nodes match the attribute
then it will not filter the list of nodes.
In `InternalHistogramTests` we were randomizing different values but `minDocCount` was hardcoded to `1`. It's important to test other values, especially `0` as it's the default. To make this possible, the test needed some adapting in the way buckets are randomly generated: all aggs need to share the same `interval`, `minDocCount` and `emptyBucketInfo`. Also assertions need to take into account that more (or less) buckets are expected depending on `minDocCount`.
This was originated by #35921 and its need to test adding empty buckets as part of the reduce phase.
Also relates to #26856 as one more key comparison needed to use `Double.compare` to properly handle `NaN` values, which was triggered by the increased test coverage.
Right now using the `GET /_tasks/<taskid>` API and causing a task to opt
in to saving its result after being completed requires permissions on
the `.tasks` index. When we built this we thought that that was fine,
but we've since moved towards not leaking details like "persisting task
results after the task is completed is done by saving them into an index
named `.tasks`." A more modern way of doing this would be to save the
tasks into the index "under the hood" and to have APIs to manage the
saved tasks. This is the first step down that road: it drops the
requirement to have permissions to interact with the `.tasks` index when
fetching task statuses and when persisting statuses beyond the lifetime
of the task.
In particular, this moves the concept of the "origin" of an action into
a more prominent place in the Elasticsearch server. The origin of an
action is ignored by the server, but the security plugin uses the origin
to make requests on behalf of a user in such a way that the user need
not have permissions to perform these actions. It *can* be made to be
fairly precise. More specifically, we can create an internal user just
for the tasks API that just has permission to interact with the `.tasks`
index. This change doesn't do that, instead, it uses the ubiquitus
"xpack" user which has most permissions because it is simpler. Adding
the tasks user is something I'd like to get to in a follow up change.
Instead, the majority of this change is about moving the "origin"
concept from the security portion of x-pack into the server. This should
allow any code to use the origin. To keep the change managable I've also
opted to deprecate rather than remove the "origin" helpers in the
security code. Removing them is almost entirely mechanical and I'd like
to that in a follow up as well.
Relates to #35573
Currently when a Fuzziness instance with custom AUTO distance values gets
written to XContent, the customized lower and upper distance values are ommited
and can consequently not be parsed back. This changes this to write the String
including the optional custom values when writing to XContent and fixes the
tests that should have caught this in the first place, e.g. by adding the custom
low and high distance values to the equality check.
When the grouping key of a GROUP BY is a painless script (functions are
involved), the data type of the key was incorrect in certain cases
(Boolean, IP, Date). This resulted in returning wrong data type for this
columns in the query results. E.g.:
```
SELECT COUNT(*), a > 10 AS a FROM t GROUP BY a
```
Fixes: #35662
Add a short extra sentence that explains that a missing query part in a search
request containing a "suggest" section will mean only suggestions are returned.
Closes#31640
Move classes under the same package to avoid internal classes being
exposed to the outside. Remove public visibility outside 3 classes:
EsDriver, EsDataSource and EsTypes.
The driver only has one package, namely org.elasticsearch.xpack.sql.jdbc
Use Es prefix for classes to ease name conflict and indicate their
destination
Fix#35437
This change removes the deprecated useDisMax() and useAllFields() methods from
the QueryStringQueryBuilder and related tests. The disMax parameter has already
been a no-op since 6.0 and also the useAllFields has been deprecated since 6.0
and there is a direct replacement via defaultField.
Clients can use the Kerberos V5 security mechanism and when it
used this to establish security context it failed to do so as
Elasticsearch server only accepted Spengo mechanism.
This commit adds support to accept Kerberos V5 credentials
over spnego.
Closes#34763
- Add the authentication realm and lookup realm name and type in the response for the _authenticate API
- The authentication realm is set as the lookup realm too (instead of setting the lookup realm to null or empty ) when no lookup realm is used.
* [Rollup] Add more diagnostic stats to job
To help debug future performance issues, this adds the
min/max/avg/count/total latencies (in milliseconds) for search
and bulk phase. This latency is the total service time including
transfer between nodes, not just the `took` time.
It also adds the count of search/bulk failures encountered during
runtime. This information is also in the log, but a runtime counter
will help expose problems faster
* review cleanup
* Remove dead ParseFields
`ScriptDocValues#getValues` was added for backwards compatibility but no
longer needed. Scripts using the syntax `doc['foo'].values` when
`doc['foo']` is a list should be using `doc['foo']` instead.
Closes#22919
This changes the exporter code -- most notably the `http` exporter --
to use async operations throughout the resource management and bulk
initialization code (the bulk indexing of monitoring documents was
already async).
As part of this change, this does change one semi-core aspect of the
`HttpResource` class in that it will no longer block all concurrent calls
until the first call completes with
`HttpResource::checkAndPublishIfDirty`.
Now, any parallel attempts to check the resources will be skipped until
the first call completes (success or failure). While this is a technical
change, it has very little practical impact because the existing behavior
was either quick success (then every blocked request processed) or
each request timed out and failed anyway, thus being effectively
skipped (and a burden on the system).
step times were set. The assumption was that these are always set.
Tests passed, which led me to believe this was true. There is a time
when shrunk indices have their step phase/action/step details set,
but with no time information (in the CopyExecutionStateStep).
Explain API fails for these
This commit removes the use of AbstractComponent in xpack where it was
still being extended. It has been replaced with explicit logger
declarations.
See #34488
This PR adds deprecation warnings to the relevant `Rest*Action` classes, plus tests in `Rest*ActionTests`. No updates to REST tests, the Java HLRC, or documentation were necessary, since they didn't make use of types.
MultiSearchRequests issues through `_msearch` now validate all keys
in the metadata section. Previously unknown keys were ignored
while now an exception is thrown.
Closes#35869
This commit removes the dedicated `setSoLinger` method. This simplifies
the `TcpChannel` interface. This method has very little effect as the
SO_LINGER is not set prior to the channels being closed in the abstract
transport test case. We still will set SO_LINGER on the
`MockNioTransport`. However we can do this manually.
This commit is related to #32517. It allows an "sni_server_name"
attribute on a DiscoveryNode to be propagated to the server using
the TLS SNI extentsion. Prior to this commit, this functionality
was only support for the netty transport. This commit adds this
functionality to the security nio transport.
This pull request makes the `RestGetSourceAction` return a `ResourceNotFoundException` with a proper JSON response when source or document itself is missing (see issue #33384).
Here is below a sample JSON output:
```
{
"error": {
"root_cause": [
{
"type": "resource_not_found_exception",
"reason": "Source not found [index1]/[_doc]/[1]"
}
],
"type": "resource_not_found_exception",
"reason": "Source not found [index1]/[_doc]/[1]"
},
"status": 404
}
```
added validation for complete information of step details.
also changed the rendering of explain responses so null strings are not rendered
Another thing that I changed is the format of the client-side response. I found it difficult to maintain the two subtly-different objects, so I migrated the usage of long for the fields, to Long (just as it is on the server-side).
