Upgraded from working version 1.1.0 to 2.0.2 and no longer receiving 'update' messages

[jbockerstette]

I upgraded from 1.1.0 to 2.0.2 and my working code no longer received callbacks for 'update' messages. The code works fine when using 1.1.0 but does not work in version 2.0.2. I verified that I can connect to mongo and tail without error in version 2.0.2. However, I no longer received any callbacks for changes to my collections. I followed your upgrade procedure and nothing is crashing, but I no longer get any updates.
I rolled back to 1.1.0 and now everything works again. I use a filter so that I can get updates for only the collection I want like so:

var tagsFilter = oplog.filter('*.tags');
tagsFilter.on('update', callback);

Hi @jbockerstette
Does it work without filter? Can you try that just to see if its only the filter?

I tried this in both 1.1.0 and 2.0.2. It works fine in 1.1.0 but not in 2.0.2. The only callback I get is the tail callback and the oplog.stop callback.

oplog = MongoOplog('mongodb://swagger:swagger1234@localhost:27017/local?authSource=Apple&ssl=true',
            {ns: 'Apple',
                server: {
                    sslValidate:true,
                    sslCA:ca
            }});
oplog.tail();
oplog.on('update', function (doc) {
        console.log("Got an update.");
 });

I am also trying to use 2.0.2 and seeing similar issues. However, I am using a replica set with TLS encryption and was trying to figure out if that would have anything to do with it as well. I am not seeing any inserts and no errors.

Just wondering if you have an on("error",... handler set up and/or an on("end"... Maybe that would give a clue as to why?

Sorry, should have updated this, I got it to work. It all comes down to making sure you are connected to the 'local' DB so that the oplog collection is available.

I'm also experiencing this with 2.1.4, and in my case it appears to be because of the use of the ns field in the options. If I remove it everything works fine.
