Regression introduced in 2.5.5 by SERVER-11389.
Upsert operations will fail with error "Cannot create base during insert of update" when the query document includes multiple equality predicates on the same field. Query predicates that use $all are affected; query predicates that use $and with multiple predicates that are explicitly given on the same field are also affected.
See the following example:
> db.version() 2.6.1 > db.foo.drop() false > db.foo.update({a:{$all:[0,1]}},{$set:{b:1}},{upsert:true}) WriteResult({ "nMatched" : 0, "nUpserted" : 0, "writeError" : { "code" : 12, "errmsg" : "Cannot create base during insert of update. Caused by :ConflictingUpdateOperators Cannot update 'a' and 'a' at the same time" } })
The following illustrates how to work around the issue in the above example:
> db.foo.update({$and:[{a:{$elemMatch:{$lte:0,$gte:0}}},{a:{$elemMatch:{$lte:1,$gte:1}}}]},{$set:{b:1}},{upsert:true})
WriteResult({
"nMatched" : 0,
"nUpserted" : 1,
"nModified" : 0,
"_id" : ObjectId("53691eda8f8f0d777fb2be69")
})
