exclude nModified from legacy write results

XMLWordPrintableJSON

    • Fully Compatible
    • ALL
    • Hide

      With the 2.6 shell connected to a 2.4 server:

      repl0:PRIMARY> db.serverBuildInfo().version
2.4.9
repl0:PRIMARY> db.coll.drop()
true
repl0:PRIMARY> db.coll.insert([{_id: 1}])
Cannot use commands write mode, degrading to compatability mode
WriteResult({ "nInserted" : 1 })
repl0:PRIMARY> var bulk = db.coll.initializeOrderedBulkOp()
repl0:PRIMARY> bulk.find({_id: 1}).update({$set: {x: 1}})
repl0:PRIMARY> bulk.execute()
BulkWriteResult({
    "writeErrors" : [ ],
    "writeConcernErrors" : [ ],
    "nInserted" : 0,
    "nUpserted" : 0,
    "nMatched" : 1,
    "nModified" : 0,
    "nRemoved" : 0,
    "upserted" : [ ]
})
      Show
      With the 2.6 shell connected to a 2.4 server: repl0:PRIMARY> db.serverBuildInfo().version 2.4.9 repl0:PRIMARY> db.coll.drop() true repl0:PRIMARY> db.coll.insert([{_id: 1}]) Cannot use commands write mode, degrading to compatability mode WriteResult({ "nInserted" : 1 }) repl0:PRIMARY> var bulk = db.coll.initializeOrderedBulkOp() repl0:PRIMARY> bulk.find({_id: 1}).update({$set: {x: 1}}) repl0:PRIMARY> bulk.execute() BulkWriteResult({ "writeErrors" : [ ], "writeConcernErrors" : [ ], "nInserted" : 0, "nUpserted" : 0, "nMatched" : 1, "nModified" : 0, "nRemoved" : 0, "upserted" : [ ] })

      If nModified cannot be returned, like with a legacy write using GLE, then it should be excluded to indicate it is not valid. This is true in both the shell, and server (including mongos).
