This is related to #28898. This PR implements pooling of bytes arrays
when reading from the wire in the http server transport. In order to do
this, we must integrate with netty reference counting. That manner in
which this PR implements this is making Pages in InboundChannelBuffer
reference counted. When we accessing the underlying page to pass to
netty, we retain the page. When netty releases its bytebuf, it releases
the underlying pages we have passed to it.
This is related to #31325. There is currently information about the
get-trial-status api on the start-trial api documentation page. It also
has the incorrect route for that api. This commit removes that
information as the start-trial page properly links to a page providing
documenation about get-trial-status.
This commit adds the is-write-index flag for aliases.
It allows requests to set the flag, and responses to display the flag.
It does not validate and/or affect any indexing/getting/updating behavior
of Elasticsearch -- this will be done in a follow-up PR.
This commit introduces a new property to IndexMetaData called
RolloverInfo. This object contains a map containing the aliases
that were used to rollover the related index, which conditions
were met, and at what time the rollover took place.
much like the `index.creation_date`, it captures the approximate time
that the index was rolled over to a new one.
An expected exception is only thrown when there are documents in the index
created in the test setup. Fixed the test by making sure there is at least one.
Closes#31307
This change moves tests in `smoke-test-rank-eval-with-mustache` into the main
ranking evaluation module by declaring that the integration testing cluster
requires the `lang-mustache` plugin. This avoids having to maintain the qa
project for only one basic test suite.
This commit adds a new QA sub project to the discovery-ec2 plugin.
This project uses a fixture to test the plugin using a multi-node cluster.
Once all nodes are started, the nodes transport addresses are written
in a file that is later read by the fixture.
Add a `NodeSelector` so that users can filter the nodes that receive
requests based on node attributes.
I believe we'll need this to backport #30523 and we want it anyway.
I also added a bash script to help with rebuilding the sniffer parsing
test documents.
While the other two ranking evaluation metrics (precicion and reciprocal rank)
already provide a more detailed output for how their score is calculated, the
discounted cumulative gain metric (dcg) and its normalized variant are lacking
this until now. Its not really clear which level of detail might be useful for
debugging and understanding the final metric calculation, but this change adds a
`metric_details` section to REST output that contains some information about the
evaluation details.
This pull request removes the relationship between the state
of persistent task (as stored in the cluster state) and the status
of the task (as reported by the Task APIs and used in various
places) that have been confusing for some time (#29608).
In order to do that, a new PersistentTaskState interface is added.
This interface represents the persisted state of a persistent task.
The methods used to update the state of persistent tasks are
renamed: updatePersistentStatus() becomes updatePersistentTaskState()
and now takes a PersistentTaskState as a parameter. The
Task.Status type as been changed to PersistentTaskState in all
places were it make sense (in persistent task customs in cluster
state and all other methods that deal with the state of an allocated
persistent task).
Currently we maintain a compatibility map of http status codes in both
the netty4 and nio modules. These maps convert a RestStatus to a netty
HttpResponseStatus. However, as these fundamentally represent integers,
we can just use the netty valueOf method to convert a RestStatus to a
HttpResponseStatus.
This commit modifies the Sys V init startup scripts to only modify
vm.max_map_count if needed. In this case, needed means that the current
value is less than our default value of 262144 maps.
We might lose messages between getCapturedRequestsAndClear calls.
This commit makes sure that both getCapturedRequestsAndClear and
getCapturedRequestsByTargetNodeAndClear are atomic.
If you run `./gradlew -p qa bwcTest -Dtests.distribution=zip` then we
need to resolve older versions of the default distribution. Since those
aren't available in maven central, we need add the elastic maven repo to
the project.
This is related to #28898. With the addition of the http nio transport,
we now have two different modules that provide http transports.
Currently most of the http logic lives at the module level. However,
some of this logic can live in server. In particular, some of the
setting of headers, cors, and pipelining. This commit begins this moving
in that direction by introducing lower level abstraction (HttpChannel,
HttpRequest, and HttpResonse) that is implemented by the modules. The
higher level rest request and rest channel work can live entirely in
server.
For 6.3 we renamed the `tar` and `zip` distributions to `oss-tar` and
`oss-zip`. Then we added new `tar` and `zip` distributions that contain
x-pack and are licensed under the Elastic License. Unfortunately we
accidentally generated POM files along side the new `tar` and `zip`
distributions that incorrectly claimed that they were Apache 2 licensed.
Oooops.
This fixes the license on the POMs generated for the `tar` and `zip`
distributions.
This commit changes the ack timeout mechanism so that its behavior is closer to the publish
timeout, i.e., it only comes into play after committing a cluster state. This ensures for example that
an index creation request with a low (ack) timeout value does not return before the cluster state
that contains information about the newly created index is even committed.
This adds a `description` to ML filters in order
to allow users to describe their filters in a human
readable form which is also editable (filter updates
to be added shortly).
Due to a runtime classpath clash, featureAware task was failing on JVMs
higher than 1.8 (since the ASM version from Painless was used instead
which does not recognized Java 9 or 10 bytecode) causing the task to
fail.
This commit excludes the ASM dependency (since it's not used by SQL
itself).
Packaging tests are occasionally failing (#30295) because of very slow index
template creation. It looks like the slow part is updating the on-disk cluster
state, and this change will help to confirm this.
Many fixtures have similar code for writing the pid & ports files or
for handling HTTP requests. This commit adds an AbstractHttpFixture
class in the test framework that can be extended for specific testing purposes.
We currently have a specific REST action to retrieve all aliaes, which
uses internally the get index API. This doesn't seem to be required
anymore though as the existing RestGetAliaesAction could as well take
the requests with no indices and aliases specified.
This commit removes the RestGetAllAliasesAction in favour of using
RestGetAliasesAction also for requests that don't specify indices nor
aliases. Similar to #31129.
x-pack/sql depends on lang-painless which depends on ASM 5.1
FeatureAwareCheck needs ASM 6
This is a hack to strip ASM5 from the classpath for FeatureAwareCheck
This is related to #27260. Currently when we queue a write with a
channel we set OP_WRITE and wait until the next selection loop to flush
the write. However, if the channel does not have a pending write, it
is probably ready to flush. This PR implements an optimistic flush logic
that will attempt this flush.
- All rollup pages should be marked as experimental instead of just
the top page
- While the job config docs state which aggregations are allowed, adding
a section which specifically details this in one place is more convenient
for the user
- Add a clarification that the DeleteJob API does not delete the rollup
data, just the rollup job.
Cross-cluster search selects a subset of nodes for each remote cluster
and sends requests only to them, which will act as a proxy and properly
redirect such requests to the target nodes that hold the relevant data.
What happens today is that every time we send a request to a remote
cluster, it will be sent to the next node in the proxy list
(in round-robin fashion), regardless of whether the target node is
already amongst the ones that we are connected to. In case for instance
we need to send a shard search request to a data node that's also one of
the selected proxy nodes, we may end up sending the request to it
through one of the other proxy nodes.
This commit optimizes this case to make sure that whenever we are
already connected to a remote node, we will send a direct request rather
than using the next proxy node.
There is a side-effect to this, which is that round-robin will be a bit
unbalanced as the data nodes that are also selected as proxies will
receive more requests.
