We had several problems with Java Serializatin in the past. At some point
in the Java 1.7.x series JDKs where not compatible anymore when java
serialization (ObjectStream) was used to exchange objects. In elasticsearch
we used this to serialize exceptions across the wire which caused several problems
with incompatible JDKs. While causing lot of trouble this essentially prevented
users from moving forward and upgrade their JVMs. To prevent these kind of issues
this commit removes the dependency on java serialization entirely and bans the
usage of ObjectOutputStream and ObjectInputStream entirely.
Yet, we can't fully serialize all exception anymore such that this commit
is best effort and adds hand written serialization to all elasticsearch exceptions
as well to a selected set of JDK and Lucene exceptions. (see StreamOutput#writeThrowable /
StreamInput.readThrowable). Stacktraces should be preserved for all exceptions while
several names might be replaced with ElasticsearchException if there is no mapping for
the given exception.
Added validation for all inner queries that any already refactored query may hold. Added also tests around this. At the end of the refactoring validate will be called by SearchRequest#validate during TransportSearchAction execution, which will call validate against the top level query builder that will need to go and validate its data plus all of its inner queries, and so on.
Closes#11889
In order to support older RPM based distributions like CentOS5,
we should have one RPM available, which is not signed.
This commit creates an unsigned RPM first, then moves it over to
target/releases during the build, then builds a signed RPM.
The unsigned one is uploaded via S3, where as the signed one is
used for the repositories.
In addition, you can now build an RPM without having to specify
any gpg credentials due to offloading this into a maven profile
that is only activated when specifying `rpm.sign` property.
Closes#11587
instead of maintaining a thread local cache in the PercolatorQueriesRegistry.
Before PercolatorQueriesRegistry had its own cache, because all the queries had to forcefully opt out of caching. Nowadays in master small segments are never cached by the query cache, so the reason for the dedicated cache is no longer valid.
This is a standalone wrapper around Mockito, it allows us to use
it without granting dangerous permissions to all of our code.
