Re: [Pharo-users] Oops! Invalid username or password when saving Settings on smalltalkhub
Thanks for the report. Stef Le 6/8/15 22:06, Andrei Chis a écrit : 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.

Re: [Pharo-users] direct image code exchange
Hi! It is great that people are interested in sharing information between images. GTChatter was the first try and we will come with a new solution. What is the most urgent information you want to share between images? Source code? I am curious about your use cases: Do you want to share information between images on the same computer? Between your computers? Between co-workers?

Re: [Pharo-users] MongoDB: console commands? query embedded indexed fields?
Hi Norbert, Hi Phil,
thanks for your help! Now I know what the problem is/was. :-)))
The query was right, the index was used, all is fine.
BUT:
I used an inspector to look at the query's result and opening the inspector
forced to load all the other objects which belong to the object found.
Explanation: I have a person which has N trips with N receipts, all with
back pointers. Opening an Inspector with one trip loads its person and all
other trips of this person hahaha. The magritte description isLazy but the
inspector forced the loading of the objects in the VOMongoRepository at
first time after image starting.
Time millisecondsToRun: [(RKATrip selectMany: {
'receipts.receiptDescription' - 'a' } asDictionary) size] 764 .
Time millisecondsToRun: [(RKATrip selectMany: {
'receipts.receiptDescription' - 'a' } asDictionary) inspect] 17234
So, I messed around with myself.
Currently I do not have so much data but I hope in future there will be a
lot and I want the application prepared for that.
BTW: I found this nice document:

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.
Usually it does.
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?
The handling of indexes needs to be automatic. 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

Hi Norbert,
I didn't want to use use database for queries but for defining the

will set the indexes within the mongo console.
The explain option is very helpful I did not know this.
