This commit removes and now forbids all uses of
com.google.common.hash.HashCode, com.google.common.hash.HashFunction,
and com.google.common.hash.Hashing across the codebase. This is one of
the few remaining steps in the eventual removal of Guava as a
dependency.
Relates #13224
While refactoring has_child and has_parent query we lost an important detail around types. The types that the inner query gets executed against shouldn't be the main types of the search request but the parent or child type set to the parent query. We used to use QueryParseContext#setTypesWithPrevious as part of XContentStructure class which has been deleted, without taking care though of setting the types and restoring them as part of the innerQuery#toQuery call.
Meanwhile also we make sure that the original context types are restored in PercolatorQueriesRegistry

Add paranoia
Groovy holds on to a classloader, so check it before compilation too.
I have not reviewed yet what Rhino is doing, but just be safe.

Add SpecialPermission to guard exceptions to security policy.
In some cases (e.g. buggy cloud libraries, scripting engines), we must
grant dangerous permissions to contained cases. Those AccessController blocks
are dangerous, since they truncate the stack, and can allow privilege escalation.
This PR adds a simple permission to check before each one, so that unprivileged code
like groovy scripts, can't do anything they shouldn't be allowed to do otherwise.
GCE plugin tries to start immediately gce discovery even if we don't
set discovery.type. This commmit adds check `discovery.type` and
other required parameters before loading gce plugin.
closes#13614
Now that groovy is factored out, we contain this dangerous stuff there.
TODO: look into those test hacks inspecting class protection domains, maybe we can
clean that one up too.
TODO: generalize the GroovyCodeSourcePermission to something all script engines check,
before entering accesscontrollerblocks. this way e.g. groovy script cannot coerce
python engine into creating something with more privs if it gets ahold of it... we
should probably protect the aws/gce hacks in the same way.
This commit fixes ping timeout settings inconsistencies in
ZenDiscovery. In particular, the documentation refers to the ping
timeout setting as discovery.zen.ping_timeout but the code was
ultimately using discovery.zen.ping.timeout if this was set.
This commit also changes all instances of the raw string
“discovery.zen.ping_timeout” to the constant
o.e.d.z.ZenDiscovery.SETTING_PING_TIMEOUT.
Finally, this commit removes the legacy setting
"discovery.zen.initial_ping_timeout".
Closes#6579, #9581, #9908
I want to refactor scripting engines so we can contain dangerous "God-like" permissions
like createClassloader/sun.reflect. These are used for dynamic class generation (scripts, mocks).
This will mean some refactoring to ES core.
But first lets get the plugins in order first. I removed those permissions globally, and
fixed grants for lang-javascript, lang-python, securemock so that everything works.
lang-javascript needs no code changes, because rhino is properly written :)
lang-python needs accesscontroller blocks. securemock was already working as of 1.1
This is just a baby step, to try to do some of this incrementally! It doesn't yet provide
us anything.
Until now we had a cloud-azure plugin which is providing 3 distinct features:
* discovery on Azure
* snapshot/restore on Aure
* SMB store
This commit splits the plugin by feature so people can use either one or the other or both features.
Doc is updated accordingly.
We moved a lot of repositories into elasticsearch, but in their new
location they retained their LICENSE.txt and NOTICE.txt files. These are
all the same, and having the license and notice and the root of the
repository should be sufficient.
Plugin tests require having rest-api tests, and currently copy that spec
from a directory in the root of the plugin source into the test
resources. This change moves the rest-api-spec dir into test resources
so it is like any other test resources. It also removes unnecessary
configuration for resources from the shared plugin pom.
This commit removes unnecesssary use of ExceptionHelpers where we actually
should serialize / deserialize the actual exception. This commit also
fixes one of the oddest problems where the actual exception was never
rendered / printed if `all shards failed` due to a missing cause.
This commit unfortunately doesn't fix Snapshot/Restore which is almost
unfixable since it has to serialize XContent and read from it which can't
transport exceptions.
When running a RestIT test from the IDE, you actually start an internal node which does not automatically load the plugin you would like to test.
We need to add:
```java
@Override
protected Collection<Class<? extends Plugin>> nodePlugins() {
return pluginList(PLUGIN_HERE.class);
}
```
Everything works fine when running from maven because each test basically:
* installs elasticsearch
* installs one plugin
* starts elasticsearch with this plugin loaded
* runs the test
Note that this PR only fixes the fact we run an internal cluster with the expected plugin.
Cloud tests will still fail when run from the IDE because is such a case you actually start an internal node with many mock plugins.
And REST test suite for cloud plugins basically checks if the plugin is running by checking the output of NodesInfo API.
And we check:
```yml
- match: { nodes.$master.plugins.0.name: cloud-azure }
- match: { nodes.$master.plugins.0.jvm: true }
```
But in that case, this condition is certainly false as we started also `mock-transport-service`, `mock-index-store`, `mock-engine-factory`, `node-mocks`, `asserting-local-transport`, `mock-search-service`.
