Small refactorings to make the MessageChannelHandler more extensible.
Also allowed access to the different netty pipelines
This is the fix after the first version had problems with the HTTP
transport due to wrong reusing channel handlers, which is the reason
why tests failed.
Relates #6889Closes#6915
It's now possible to inject action filters from plugins via `ActionModule#registerFilter` through the following code:
```
public void onModule(ActionModule actionModule) {
actionModule.registerFilter(MyFilter.class);
}
```
Also made `TransportAction#execute` methods final to enforce the execution of the filter chain. By default the chain is empty though.
Note that the action filter chain is executed right after the request validation, as the filters might rely on a valid request to do their work.
Closes#6921
Today when we start a `TransportClient` we use the given transport
addresses and create a `DiscoveryNode` from it without knowing the
actual nodes version. We just use the `Version.CURRENT` which is an
upper bound. Yet, the other node might be a version less than the
currently running and serialisation of the nodes info might break. We
should rather use a lower bound here which is the version of the first
release with the same major version as `Version.CURRENT` since this is
what we officially support.
This commit moves to use the minimum major version or an RC / Snapshot
if the current version is a snapshot.
Closes#6894
Adds the ability to the Term Vector API to generate term vectors for some
chosen fields, even though they haven't been explicitely stored in the index.
Relates to #5184Closes#6567
The bulk processor tries to acquire all leases for the semaphore to wait
for all pending requests. Yet, we should release them afterwards again to
ensure we don't ever deadlock if there is a bug in the processor.
This commit also adds a testcase for this method
It's now possible to register watchers along with a specified check frequency. There are three frequencies: low, medium, high. Each one is associated with a check interval that determines how frequent the watchers will check for changes and notify listeners if needed. By default, the intervals are 5s, 30s and 60s respectively, but they can also be customized in the settings. also:
- Added the WatcherHandle construct by which one can stop it (remove it) and resume it (re add it). Also provices access to the watchers itself and the frequency by which it's checked
- Change the default frequency to 30 seconds interval (used to be 60 seconds). The only watcher that is currently effected by this is the script watcher (now auto-loading scripts will auto-load every 30 seconds if changed)
This is to prevent a rare racing condition where the very same shard gets allocated to the node after our sanity check that the cluster state didn't check and the actual deletion of the files.
Closes#6902
This results in unstable tests, most likely due to Channels being mixed
up by wrongly creating the pipelines. Needs investigation and a test.
This reverts commit db7f0d36af.
The IndexingMemoryController determines the amount of indexing buffer size and translog buffer size each shard should have. It takes memory from inactive shards (indexing wise) and assigns it to other shards. To do so it needs to know about the addition and closing of shards. The current implementation hooks into the indicesService.indicesLifecycle() mechanism to receive call backs, such shard entered the POST_RECOVERY state. Those call backs are typically run on the thread that actually made the change. A mutex was used to synchronize those callbacks with IndexingMemoryController's background thread, which updates the internal engines memory usage on a regular interval. This introduced a dependency between those threads and the locks of the internal engines hosted on the node. In a *very* rare situation (two tests runs locally) this can cause recovery time outs where two nodes are recovering replicas from each other.
This commit introduces a a lock free approach that updates the internal data structures during iterations in the background thread.
Closes#6892
FieldMapper has two methods
`Filter termsFilter(List values, @Nullable QueryParseContext)` which is supposed
to work on the inverted index and
`Filter termsFilter(QueryParseContext, List, QueryParseContext)` which is
supposed to work on field data. Let's rename the second one to
`fieldDataTermsFilter` and remove the unused `QueryParseContext`.
Close#6888
If you call `bin/plugin --remove es-plugin` the plugin got removed but the file `bin/plugin` itself was also deleted.
We now don't allow the following plugin names:
* elasticsearch
* plugin
* elasticsearch.bat
* plugin.bat
* elasticsearch.in.sh
* service.bat
Closes#6745
With the removal of setNextScore in #6864, script engines must use
the Scorer to find the score of a document. The DocLookup is updated
appropriately to do this, but most script engines require a Number to be
bound for numeric variables. Groovy already had an encapsulation for
this funtionality, and this moves it out to be shared with other script
engines.
closes#6898
While it would be nice to do this all the way up the chain (into
score functions), this at least removes the weird dual
setNextScore/setScorer for SearchScripts.
closes#6864
This fixes an issue introduced by the serialization changes in #6486
which are not needed at all. Node that the serialization itself is not broken
but the TransportClient uses its own version on initial connect and getting
the NodeInfos.
Today we synchronize when updating the IndexFieldDataService
datastructures. This might unnecessarily block progress if multiple
request need different fielddata instance for different fields.
This commit also fixes clear calls to actually consistently clear
the caches in the case of an exception.
Closes#6855
As a SizeValue is used for serializing the thread pool size, a negative number
resulted in throwing an exception when deserializing (using -ea an assertionerror
was thrown).
This fixes a check for changing the serialization logic, so that negative numbers are read correctly, by adding an internal UNBOUNDED value.
Closes#6325Closes#5357
Due to change introduced in #6825, we now start a local gateway recovery for replicas, if the source node can not be found. The recovery then fails because we never recover replicas from disk.
Closes#6879
