Re: [Pharo-users] "Oops! Invalid username or password" when saving Settings on smalltalkhub

>From what I remember the logout issue is caused by proxies caches and the fact that smalltalk hub does not set any headers that prevent/invalidate caching. We are having this problem all the time on our university network. To make it worse sometimes after I log out I get the home page of the previous logged in user that accessed smalltalk hub. If the underlying cause is caching then smalltalk hub could add some headers to invalidate it. We really only get these kinds of problems on smalltalk hub.

We have instability with smalltalkhub and one of these days we should do a pass but we are really busy pushing Pharo 50. You can try squeaksource3 hosted by gemtalksystem.

The rule of thumb is that if you use where clause like b = , c = , a= than you need an compound index in the same order being index(b,c,a). This is handled by the database when it analyzes the query it tries to find an appropriate index. Or seeing it from the other side: If you issue a query with index and the index does not fit the query it is a problem anyway. Are you sure you have only this one thing in the where query? I use e.g. COInstalledApp selectOne: { 'device.id' -> aString. 'application.__id' -> anApplication voyageId } asDictionary on a collection that has approx. 1 Mio. entires and it is fast. I didn't check with explain but I'll do if I find time :) If I were you I would step in the debugger down to the Voyage part after serialization. Then you have the exact Dictionary that is used to send to mongo. You can then use this query to do an "explain" on it and that should show you something. Another thing you can try (although I don't think makes any difference) is to use the non-javascript query variant. That would be Trip selectMany: { 'receipts' -> { 'receiptDescription' -> 'Tankquittung' } asDictionary } asDictionary Norbert > Regards > Sabine > > 2015-08-04 14:47 GMT+02:00 Sabine Manaa <manaa.sabine(a)gmail.com <mailto:manaa.sabine@gmail.com>>: > > > > Hi Norbert, > > > > I didn't want to use "use database" for queries but for defining the index from within smalltalk.

Re: [Pharo-users] MongoDB: console commands? query embedded indexed fields?

by phil＠highoctane.be

Hi Sabine, Not related to these indexes per se but I had performance problems associated with the fact that MongoTalk asked for all collections again and again. I cached them (in my own MongoTalk version) and added debugging to the MongoOperations so that I could see what was going on. This alone sped up the thing by a huge factor. My collections have more than 20-30K entries and I am querying them extensively. No perf problem even without the indexes. How many entries are you scanning?

Re: [Pharo-users] MongoDB: console commands? query embedded indexed fields?

by Sabine Manaa

Norbert, I have to come back to your answer. With the .explain option, I can see, how performance is with and without index on the _mongo console_. As an example, I see: with index only 2 objects scanned, without: 200. Performance is perfect with index. But _from smalltalk_, it seems to iterate over all objects, also with the index set. Slow. You wrote: "The index will be selected automatically." It seems that it does not. My question: MongoQuery has an attribute named "where" which is filled with the mentioned "receipts.receiptDescription". Because of the name of this attribute "where" and the slow performance, I assume that the mongo classes use the $where command: http://docs.mongodb.org/manual/reference/operator/query/where/ Is this right? In this case with the statement Trip selectMany: { 'receipts.receiptDescription' -> 'Tankquittung' } asDictionary the index would not be set automatically. "The $where provides greater flexibility, but requires that the database processes the JavaScript expression or function for each document in the collection. " Then my question is if the mongo classes support database queries with index and if yes, how. I am very interested in your opinion and I think other users should have the same requirements (querying indexed variables) - how did they solve this?
