Batch write with ranged query predicate mixed with single target triggers invariant on mongos

    • Type: Icon: Bug Bug
    • Resolution: Fixed
    • Priority: Icon: Major - P3 Major - P3
    • 3.6.5, 4.0.0-rc0
    • Affects Version/s: 3.6.2, 3.7.3
    • Component/s: Sharding
    • None
    • Fully Compatible
    • v3.6
    • Sharding 2018-04-23, Sharding 2018-05-07

      This is because whenever a targeted write need to be sent to multiple shards, the endpoint shard version will be overriden to have ignored version. If the batch has a mixed of writes that are multi target and single targets, it will end up with endpoints that have the original versions and the one with ignored versions even though they are the same shards. Since the batchMap is keyed by the ShardEndPoint (which is the (shard, version) pair), it will miss this check and end up with a map with multiple entries for the same shard. This will in turn, trigger the invariant here.
