This is a fork from ticket SERVER-12595 which was used to fix a similar problem with findAndModify.
The 'text' command is not aborting the command when provided a maxTimeMS.
> db.testData.drop() true > for (var i = 1; i <= 100000; i++) db.testData.insert( { x : i, "text" : "Now is the time for all good men to come to the aid of..." } ) SingleWriteResult({ "writeErrors" : [ ], "writeConcernErrors" : [ ], "nInserted" : 1, "nUpserted" : 0, "nUpdated" : 0, "nModified" : 0, "nRemoved" : 0, "upserted" : [ ] })> db.testData.stats() { "ns" : "test.testData", "count" : 100000, "size" : 11200000, "avgObjSize" : 112, "storageSize" : 22507520, "numExtents" : 7, "nindexes" : 2, "lastExtentSize" : 11325440, "paddingFactor" : 1, "systemFlags" : 1, "userFlags" : 1, "totalIndexSize" : 21723632, "indexSizes" : { "_id_" : 3262224, "text_text" : 18461408 }, "ok" : 1 } > db.testData.runCommand( "text" , { search : "good" , maxTimeMS : 100 } ) { "results" : [ <snip/> ], "stats" : { "nscanned" : NumberLong(100000), "nscannedObjects" : NumberLong(100000), "n" : 100, "timeMicros" : 145226 }, "ok" : 1 }
In the server log we get confirmation that the command took longer than 100ms.
[conn1] command test.$cmd command: { text: "testData", search: "good", maxTimeMS: 100.0 } keyUpdates:0 numYields:0 locks(micros) r:148545 reslen:13119 148ms
The above text command was modified from http://docs.mongodb.org/manual/reference/command/text/.
I also tried the manual command invocation with the same results:
> db.runCommand( { "text" : "testData", search : "good" , maxTimeMS : 100 } )
{
"results" : [
// Removed.
],
"stats" : {
"nscanned" : NumberLong(100000),
"nscannedObjects" : NumberLong(100000),
"n" : 100,
"timeMicros" : 135148
},
"ok" : 1
}
