We now have a remote cluster client exposed which can
talk to a given remote cluster and manages reconnects etc.
This makes code more readable than using the transport layer directly.
The .watcher-history-* template is currently using a plugin-custom index setting xpack.watcher.template.version,
which prevents this template from being installed in a mixed OSS / X-Pack cluster, ultimately
leading to the situation where an X-Pack node is constantly spamming an OSS master with (failed)
template updates. Other X-Pack templates (e.g. security-index-template or security_audit_log)
achieve the same versioning functionality by using a custom _meta field in the mapping instead.
This commit switches the .watcher-history-* template to use the _meta field instead.
The current documentation isn't very clear about how incomplete dates are
treated when specifying custom formats in a `range` query. This change adds a
note explaining how missing month or year coordinates translate to dates that
have the missings slots filled with unix time start date (1970-01-01)
Closes#30634
Persistent tasks was moved from X-Pack to core in #28455.
However, registration of the named writables and named
X-content was left in X-Pack.
This change moves the registration of the named writables
and named X-content into core. Additionally, the persistent
task actions are no longer registered in the X-Pack client
plugin, as they are already registered in ActionModule.
Today, the `ClusterApplier` and `MasterService` both use the
`ClusterStateTaskListener` interface to notify their callers when asynchronous
activities have completed. However, this is not wholly appropriate: none of the
callers into the `ClusterApplier` care about the `ClusterState` arguments that
they receive. This change introduces a dedicated ClusterApplyListener
interface for callers into the `ClusterApplier`, to distinguish these listeners
from the real `ClusterStateTaskListener`s that are waiting for responses from
the `MasterService`.
This change adds a simple header to the transport client
that is present on the servers thread context that ensures
we can detect if a transport client talks to the server in a
specific request. This change also adds a header for xpack
to detect if the client has xpack installed.
This commit ensures the delete of the upgrade_is_oss indicator for
the packaging tests is always deleted before each run. It works by
moving the check on version which skips the task into the doFirst block,
replacing the onlyIf.

If you have an unusual umask (e.g., 0002) and clone the GitHub
repository then files that we stick into our packages like the
README.textile and the license will have a file mode of 0664 on disk yet
we expect them to be 0644. Additionally, the same thing happens with
compiled artifacts like JARs. We try to set a default file mode yet it
does not seem to take everywhere. This commit adds explicit file modes
in some places that we were relying on the defaults to ensure that the
built artifacts have a consistent file mode regardless of the underlying
build host.
This commit reintroduces 31251c9 and 63a5799. These commits introduced a
memory leak and were reverted. This commit brings those commits back
and fixes the memory leak by removing unnecessary retain method calls.
Ports the first couple tests for archive distributions from the old bats
project to the new java project that includes windows platforms,
consolidating them into one test method that tests that the
distributions can be extracted and their contents verified. Includes the
zip distributions which were not tested in the bats project.
This reverts commit 31251c9 introduced in #30695.
We suspect this commit is causing the OOME's reported in #30811 and we will use this PR to test this assertion.
Since its introduction in ES 1.4, node fault detection has been using the wrong cluster state version to send
as part of the ping request, by using always the constant -1 (ClusterState.UNKNOWN_VERSION). This can, in an
unfortunate series of events, lead to a situation where a previous stale master can regain its authority and
revert the cluster to an older state.
This commit makes NodesFaultDetection use the correct current cluster state for sending ping requests, avoiding
the situation where a stale master possibly forces a newer master to step down and rejoin the stale one.
With #30672, acking expects *all* nodes to successfully apply the cluster state.
The testElectMasterWithLatestVersion test was checking for an ack while isolating
one node in the test.
Relates to #30672
This commit adds the ability to configure how a docvalue field should be
formatted, so that it would be possible eg. to return a date field
formatted as the number of milliseconds since Epoch.
Closes#27740
The mutate function in UpdateSettingsRequestStreamableTests did not
guarantee that the masterNodeTimeout and timeout values are definitely
changed and occassionally the randomTimeValue() method would select the
sime time value as the original request which caused a failure.
Enables a rolling restart from the OSS distribution to the x-pack based distribution by preventing
x-pack code from installing custom metadata into the cluster state until all nodes are capable of
deserializing this metadata.
When doing a node restart using the test framework, the restarted node does not only use the
settings provided to the original node, but also additional settings provided by plugin extensions,
which does not correspond to the settings that a node would have on a true restart.
The cluster state acking mechanism currently incorrectly acks cluster state updates that have not
successfully been applied on all nodes. In a situation, for example, where some of the nodes
disconnect during publishing, and don't acknowledge receiving the new cluster state, the user-facing
action (e.g. create index request) will still consider this as an ack.
Lucene has a new `FeatureField` which gives the ability to record numeric
features as term frequencies. Its main benefit is that it allows to boost
queries with the values of these features and efficiently skip non-competitive
documents at the same time using block-max WAND and indexed impacts.
This is related to #29500. We are removing the ability to disable http
pipelining. This PR removes the references to disabling pipelining in
the integration test case.
A rolling upgrade from oss Elasticsearch to the default distribution of
Elasticsearch is significantly different than a full cluster restart to
install a plugin and is again different from starting a new cluster with
xpack installed. So this adds some basic tests to make sure that the
rolling upgrade that enables xpack works at all.
This also removes some unused imports from the tests that I modified in
PR #30728. I didn't mean to leave them.
The VerifyRepositoryResponse class holds a DiscoveryNode[], but the
nodes themselves are not serialized to a REST API consumer. Since we do
not want to put all of a DiscoveryNode over the wire, be it REST or
Transport since its unused, this change introduces a BWC compatible
change in ser/deser of the Response. Anything 6.4 and above will
read/write a NodeView, and anything prior will read/write a
DiscoveryNode. Further changes to 7.0 will be introduced to remove the
BWC shim and only read/write NodeView, and hold a List<NodeView> as the
VerifyRepositoryResponse internal state.
This commit reduces the Windows CLI scripts to one-liners by moving all
of the redundant logic to an elasticsearch-cli script. This commit is
only the Windows side, a previous commit covered the Linux side.
This is code that was leftover from the move to one shard by
default. Here in index metadata we were preserving the default number of
shards settings independently of the area of code where we set this
value on an index that does not explicitly have an number of shards
setting. This took into consideration the es.index.max_number_of_shards
system property, and was used in search requests to set the default
maximum number of concurrent shard requests. We set the default there
based on the default number of shards so that in a one-node case a
search request could concurrently hit all shards on an index with the
defaults. Now that we default to one shard, we expect fewer shards in
clusters and this adjustment of the node count as the max number of
concurrent shard requests is no longer needed. This commit then changes
the default number of shards settings to be consistent with the value
used when an index is created, and removes the now unneeded adjustment
in search requests.
Adding headers rather than setting them all at once seems more
user-friendly and we already do it in a similar way for parameters
(see Request#addParameter).
This commit adds a max wait timeout of one second to all the latch.await
calls made in RestClientTests. It also makes clearer that the `onSuccess`
listener method will never be called given that the underlying http
client is mocked and makes sure that `latch.countDown` is always called
Currently the first snippet in the documentation test in script-fields.asciidoc
isn't executed, although it has the CONSOLE annotation. Adding a test setup
annotation to it seems to fix the problem.
The new snapshot includes LUCENE-8324 which fixes missing checkpoint
after a fully deletes segment is dropped on flush. This snapshot should
resolves failed tests in the CorruptedFileIT suite.
Closes#30741Closes#30577
This is related to #29500 and #28898. This commit removes the abilitiy
to disable http pipelining. After this commit, any elasticsearch node
will support pipelined requests from a client. Additionally, it extracts
some of the http pipelining work to the server module. This extracted
work is used to implement pipelining for the nio plugin.
=== Char Group Tokenizer
The `char_group` tokenizer breaks text into terms whenever it encounters
a
character which is in a defined set. It is mostly useful for cases where
a simple
custom tokenization is desired, and the overhead of use of the
<<analysis-pattern-tokenizer, `pattern` tokenizer>>
is not acceptable.
=== Configuration
The `char_group` tokenizer accepts one parameter:
`tokenize_on_chars`::
A string containing a list of characters to tokenize the string on.
Whenever a character
from this list is encountered, a new token is started. Also supports
escaped values like `\\n` and `\\f`,
and in addition `\\s` to represent whitespace, `\\d` to represent
digits and `\\w` to represent letters.
Defaults to an empty list.
=== Example output
```The 2 QUICK Brown-Foxes jumped over the lazy dog's bone for $2```
When the configuration `\\s-:<>` is used for `tokenize_on_chars`, the
above sentence would produce the following terms:
```[ The, 2, QUICK, Brown, Foxes, jumped, over, the, lazy, dog's, bone,
for, $2 ]```
This commit changes the wait for a few netty threads to wait for these
threads to complete after the cluster has stopped. Previously, we were
waiting for these threads before the cluster was actually stopped; the
cluster is stopped in an AfterClass method of ESIntegTestCase, while
the wait was performed in the AfterClass of a class that extended
ESIntegTestCase, which is always executed before the AfterClass of
ESIntegTestCase.
Now, the wait is contained in an ExternalResource ClassRule that
implements the waiting for the threads to terminate in the after
method. This rule is executed after the AfterClass method in
ESIntegTestCase. The same fix has also been applied in
SecuritySingleNodeTestCase.
Closes#30563
We added this limit because we occasionally saw cases where most of the memory
usage of the cache was spent on the keys (ie. queries) rather than the values,
which caused the cache to vastly underestimate its memory usage. In recent
releases, we disabled caching on heavy `terms` queries, which were the main
source of the problem, so putting more entries in the cache should be safer.
