The `_create` API is handy way to specify an index operation should only be done if the document doesn't exist. This is currently implemented in explicit code paths all the way down to the engine. However, conceptually this is no different than any other versioned operation - instead of requiring a document is on a specific version, we require it to be deleted (or non-existent). This PR removes Engine.Create in favor of a slight extension in the VersionType logic.
There are however a couple of side effects:
- DocumentAlreadyExistsException is removed and VersionConflictException is used instead (with an improved error message)
- Update will reject version parameters if the upsert option is used (it doesn't compute anyway).
- Translog.Create is also removed infavor of Translog.Index (that's OK because their binary format was the same, so we can just read Translog.Index of the translog file)
Closes#13955
This test used indexRandom to index 4 documents. indexRandom introduces also bogus documents which were getting on the way now that we use fieldValueFactor instead of a script to determine the script of the documents. Taken out indexRandom to simplify things and make the tests more predictable.
Types are still optional, but if you do provide them, they can't be null. Split the existing constructor that accepted nnull into two, one that accepts no arguments, and another one that accepts the types argument, which must be not null.
Also trimmed down different ways of setting ids, some were misleading as they would always add the ids to the existing ones and not set them, the add prefix makes that clear. Left `addIds` method that accepts a varargs argument. Added check for ids not be null.
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.
