Plugins can now define multiple operations/contexts that they use scripts for. Fine-grained settings can then be used to enable/disable scripts based on each single registered context.
Also added a new generic category called `plugin`, which will be used as a default when the context is not specified. This allows us to restore backwards compatibility for plugins on `ScriptService` by restoring the old methods that don't require the script context and making them internally use the `plugin` context, as they can only be called from plugins.
Closes#10347Closes#10419
Now that fine-grained script settings are supported (#10116) we can remove support for the script.disable_dynamic setting.
Same result as `script.disable_dynamic: false` can be obtained as follows:
```
script.inline: on
script.indexed: on
```
An exception is thrown at startup when the old setting is set, so we make sure we tell users they have to change it rather than ignoring the setting.
Closes#10286
Allow to on/off scripting based on their source (where they get loaded from), the operation that executes them and their language.
The settings cover the following combinations:
- mode: on, off, sandbox
- source: indexed, dynamic, file
- engine: groovy, expressions, mustache, etc
- operation: update, search, aggs, mapping
The following settings are supported for every engine:
script.engine.groovy.indexed.update: sandbox/on/off
script.engine.groovy.indexed.search: sandbox/on/off
script.engine.groovy.indexed.aggs: sandbox/on/off
script.engine.groovy.indexed.mapping: sandbox/on/off
script.engine.groovy.dynamic.update: sandbox/on/off
script.engine.groovy.dynamic.search: sandbox/on/off
script.engine.groovy.dynamic.aggs: sandbox/on/off
script.engine.groovy.dynamic.mapping: sandbox/on/off
script.engine.groovy.file.update: sandbox/on/off
script.engine.groovy.file.search: sandbox/on/off
script.engine.groovy.file.aggs: sandbox/on/off
script.engine.groovy.file.mapping: sandbox/on/off
For ease of use, the following more generic settings are supported too:
script.indexed: sandbox/on/off
script.dynamic: sandbox/on/off
script.file: sandbox/on/off
script.update: sandbox/on/off
script.search: sandbox/on/off
script.aggs: sandbox/on/off
script.mapping: sandbox/on/off
These will be used to calculate the more specific settings, using the stricter setting of each combination. Operation based settings have precedence over conflicting source based ones.
Note that the `mustache` engine is affected by generic settings applied to any language, while native scripts aren't as they are static by definition.
Also, the previous `script.disable_dynamic` setting can now be deprecated.
Closes#6418Closes#10116Closes#10274
Adds a setting to disable detailed error messages and full exception stack traces
in HTTP responses. When set to false, the error_trace request parameter will result
in a HTTP 400 response. When the error_trace parameter is not present, the message
of the first ElasticsearchException will be output and no nested exception messages
will be output.
The request tracer logs in TRACE level under the `transport.tracer` log and is dynamically configurable with include and exclude arrays to filter out unneeded info. By default all requests are logged with the exception of fault detection pings (fired every second).
add the notion of tracers in the MockTransportService for testing purposes
Closes#9286
Together with #8782 it should help in the situations simliar to #8887 by adding an ability to get information about currently running snapshot without accessing the repository itself.
Closes#8887
We only have a single gatweway since es 1.3. There is no need to keep all
these abstractsion and nested packages. We can fold most of it into simpler
structures.
This change adds a 'http.publish_port' setting to the HTTP module to configure
the port which HTTP clients should use when communicating with the node. This
is useful when running on a bridged network interface or when running behind
a proxy or firewall.
Closes#8807Closes#8137
Always use the LocalGateway* equivalents
We already check in the LocalGateway whether a node is a client node, or
is not master-eligible, and skip writing the state there. This allows us
to remove this code that was previously used only for tribe nodes (which
are not master eligible anyway and wouldn't write state) and in
tests (which can shake more bugs out)
This adds HTTP pipelining support to netty. Previously pipelining was not
supported due to the asynchronous nature of elasticsearch. The first request
that was returned by Elasticsearch, was returned as first response,
regardless of the correct order.
The solution to this problem is to add a handler to the netty pipeline
that maintains an ordered list and thus orders the responses before
returning them to the client. This means, we will always have some state
on the server side and also requires some memory in order to keep the
responses there.
Pipelining is enabled by default, but can be configured by setting the
http.pipelining property to true|false. In addition the maximum size of
the event queue can be configured.
The initial netty handler is copied from this repo

This commit adds the ability to enable / disable relocations
on an entire cluster or on individual indices for either:
* `primaries` - only primaries can rebalance
* `replica` - only replicas can rebalance
* `all` - everything can rebalance (default)
* `none` - all rebalances are disabled
similar to the allocation enable / disable functionality.
