Fixes pre and post offset serialisation for histogram aggs #7313

The problem here is that it would break multi-version clusters. We still need to read/write vLong depending on in/out.getVersion so that at least positive offsets work.

I was first afraid this bug might have been introduced by #6980 but it seems that it is not the case, right? Just left a comment about backward compatibility of the stream. Otherwise it looks good. |

Yep, I think it was present before I made that change and refactored the class. Have updated the serialisation to solve the backwards compatibility issue |
|
I think we shouldn't change the serialization format in a minor release, so I would rather fix it in 1.4.0 only? Otherwise LGTM. |

It think this is problematic since this forces LocalTransport all the time even if we run with network tests. I think you should add a setting to AssertingLocalTransport that allows you to set the min version? then you can just pass the min version here instead of the TransportModule.TRANSPORT_TYPE_KEY I hope that makes sense

LGTM thanks for all the iterations! |
Changes the serialisation of pre and post offset to use Long instead of VLong so that negative values are supported. This actually only showed up in the case where minDocCount=0 as the rounding is only serialised in this case. Closes #7312
