The big win here is catching tests that are incorrectly named and will
be skipped by gradle, providing a false sense of security.
The whole thing takes about 10 seconds on my Macbook Air, not counting
compiling the test classes, which seems worth it. Because this runs as
a gradle task with propery UP-TO-DATE handling it can be skipped if the
tests haven't been changed which should save some time.
I chose to keep this in test:framework rather than a new subproject of
buildSrc because ESIntegTestCase and doesn't inroduce any additional
dependencies.
DiscoveryService was a bridge into the discovery universe. This is unneeded and we can just access discovery directly or do things in a different way.
One of those different ways, is not having a dedicated discovery implementation for each our dicovery plugins but rather reuse ZenDiscovery.
UnicastHostProviders are now classified by discovery type, removing unneeded checks on plugins.
Closes#16821
This commit works around an issue with hostname verification in HttpClient when using IPv6
addresses in URLs. When an IPv6 address is used in a URL it is typically wrapped with square
brackets. The hostname verifier for HttpClient does not recognize these as valid IPv6 addresses
and instead treats them as a DNS name. We wrap the strict hostname verifier for this version
of HttpClient and strip brackets if we need to.
The corresponding issue in HttpClient is https://issues.apache.org/jira/browse/HTTPCLIENT-1698
but the fix has not been released yet in a stable version.
Today we might start a node and some of the paths might not have the
required permissions. This commit goes through all data directories as
well as index, shard and state directories and ensures we have write access.
To make this work across all OS etc. we are trying to write a real file
and remove it again in each of those directories
Today we have the notion of a snapshot inside Version.java which makes
releasing complicated since to do a release Version.java must be changed.
This commit removes all notions of snapshot from the code and allows to
switch between snapshot and release build by specifying a system property on
the build. For instance running:
```
gradle run -Dbuild.snapshot=false
```
will build and package a release build while the default always
builds snapshots. Calls to the main rest action will still get the snapshot
information rendered out with the response.
This commit moves IndicesRequestCache into o.e.indics and makes all API in this
class package private. All references to SearchReqeust, SearchContext etc. have been factored
out and relevant glue code has been added to IndicesService. The IndicesRequestCache is not a
simple class without any hard dependencies on ThreadPool nor SearchService or IndexShard. This now
allows to add unittests.
This commit also removes two settings `indices.requests.cache.clean_interval` and `indices.fielddata.cache.clean_interval`
in favor of `indices.cache.clean_interval` which cleans both caches.
this is a minor cleanup that detaches `IndicesRequestCache` and `IndicesQueryCache`
from guice and moves it into `IndicesService`. It also decouples the `IndexShard` and `IndexService`
from these caches which are unnecessary dependencies.
This PR renames the following three variables to fix a typo `settting` into `setting`.
* Rename a static class member:
INDEX_TRANSLOG_FLUSH_THRESHOLD_SIZE_SETTTING -> INDEX_TRANSLOG_FLUSH_THRESHOLD_SIZE_SETTING
* Rename a parameter: aSettting --> aSetting
* Rename a local variable: indexSetttings -> indexSettings
IndexShard currently holds an arbitraritly used `getQueryShardContext` that comes
out of a ThreadLocal. It's usage is undefined and arbitraty since there is also
such a method with different semantics on `IndexService` This commit removes the threadLocal on
IndexShard as well as on the context itself. It's types are now a member and the QueryShardContext
lifecycle is managed byt SearchContext which passes the types on from the SearchRequest.
There is no need for IndicesWarmer to be a global accessible class. All it needs
access to is inside IndexService. It also doesn't need to be mutable once it's not a per node
instance. This commit move IndicesWarmer to IndexWarmer and makes the default impls like field data and
norms warming an impl detail. Also the IndexShard doesn't depend on this class anymore, instead it accepts
an Engine.Warmer as a ctor argument which delegates to the actual warmer from the index.
Indices level field data cacheing belongs into IndicesService and doesn't need to be
wired by guice. This commit also moves the async cache refresh out of the class into
IndicesService such that threadpool dependencies are removed and testing / creation becomes
simpler.
This change documents the Terminal abstraction that cli tools use, as
well as simplifies the api to be a minimal set of methods to interact
with a terminal.
This commit adds a convenience method for producing random positive time
values which can be useful for places where non-negative and non-zero
time values are expected.
This commit enableds strict settings validation on node startup. All settings
passed to elasticsearch either through system properties, yaml files or any other
way to pass settings must be registered and valid. Settings that are unknown ie. due to
typos or due to deprecation or removal will cause the node to NOT start up. Plugins
have to declare all their settings on the `SettingsModule#registerSetting` and settings for
plugins that are not installed must be removed.
This commit also removes the ability to specify the nodes name via `-Des.name` or just `name` in the
configuration files. The node name must be prefixed with the node prexif like `node.name: Boom`. Left over
usage of `name` will also cause startup to fail.
When primary relocation completes, a cluster state is propagated that deactivates the old primary and marks the new primary as active.
As cluster state changes are not applied synchronously on all nodes, there can be a time interval where the relocation target has processed
the cluster state and believes to be the active primary and the relocation source has not yet processed the cluster state update and
still believes itself to be the active primary. This commit ensures that, before completing the relocation, the reloction source deactivates
writing to its store and delegates requests to the relocation target.
Closes#15900
