remove() helper exception - _printExtraInfo is not a function

[Gîanfranco P]

Expected behavior

Return the number of delete documents

Actual/current behavior

It deletes the documents but it throws an exception so it doesn't return

Steps to reproduce the actual/current behavior

db.collection.find({a : 1}).remove()

uncaught exception: TypeError: this._db._printExtraInfo is not a function :
DBQuery.prototype.remove@/Users/gpalumbo/.mongorc.js:462:5
@(shell):1:1

mongo-hacker/hacks/api.js

Lines 173 to 187 in b67f094

 DBQuery.prototype.remove = function(){ 
     for ( var k in this._query ){ 
         if ( k == "_id" && typeof( this._query[k] ) == "undefined" ){ 
             throw "can't have _id set to undefined in a remove expression"; 
         } 
     } 
  
     this._checkMulti(); 
  
     var startTime = 
         (typeof(_verboseShell) === 'undefined' || !_verboseShell) ? 0 : new Date().getTime(); 
  
     this._mongo.remove( this._ns , this._query , false ); 
     this._db._printExtraInfo("Removed", startTime); 
 }; 

work on this function was done here:

The function exists here and in my local file as well:

mongo-hacker/hacks/verbose.js

Line 6 in b67f094

 DBCollection.prototype._printExtraInfo = function(action, startTime) {

Looks like it's because the _printExtraInfo should have been added to DB.prototype._printExtraInfo.

It works in the sense that the function is executed but it's not logged – for remove(), or any other function that uses _printExtraInfo()

I think it should output the same as if you do db.collection.remove()

> db.test.remove({ a: 2 })
Removed 1 record(s) in 9ms
WriteResult({
  "nRemoved": 1
})
