Thanks Alistair This is a great initiative. Documentation is our shared knowledge. I spent time editing the document but I do not have time and the need for glorp now.

Re: [Pharo-users] VOMongoRepository

by Yanni Chiu

You might have to do: ConfigurationOfVoyageMongo loadBleedingEdge. ConfigurationOfMongoTalk loadBleedingEdge. to load the latest package versions. It worked for me, at the time I did it, but the bleeding edge packages are not a fixed code base. Unfortunately, the "stable" configuration has the "frozen" problem you're seeing, which is fixed in new code, but the configuration has not been updated.

VOMongoRepository

by Franklin Mike

Hi every body, I'm doing the Pharo Mooc and I have a proble with Voyage. I used memory repository withoud problem and when I try to use external repository(after install MongoDB) my Pharo system stop working as it was frozen. After some days I try to run VORepositoryTest it do the same thing. I'm on window 10 and my MongoDB is not protected by a password. Thanks.

P.S. If I add: UDBCSQLite3BaseConnection>>queryEncoding ^#'utf-8' I'm able to create tables and populate the database (which is as far as I've got). But of course, not sure if this is the appropriate solution. Thanks! Alistair

Re: [Pharo-users] OSProcess command - non responding image when calling often

by Paul DeBruicker

Hi Sabine, I had a Pharo 5 image where running OSProcess waitForCommand:'ls' twice would lock everything up. Following Gaston's suggestion here: http://forum.world.st/Problem-with-delay-waiting-OSSubprocess-code-on-Pharo… Fixed it for me. Maybe we hit the same issue.

Re: [Pharo-users] OSProcess command - non responding image when calling often

by Sabine Manaa

Hi Mariano, if you take the download Image from the Pharo website, then load commandShell and then zinc from the catalog browser and then do Delay delaySchedulerClass: DelayMillisecondScheduler. and then 20 timesRepeat: [OSProcess command: ('echo "Hi there"').] Then you will get the lock. Does this help to find the reason for the problem? Regards Sabine

You're right, and I had tried this, however asking the session to login results in the following: UDBCSQLite3Connection(Object)>>doesNotUnderstand: #queryEncoding PharoDatabaseAccessor>>encoding GlorpSession>>loginIfError: GlorpSession>>login GlorpBookDescriptorSystem class>>getSession UndefinedObject>>DoIt In my image at least, there are no implementers of #queryEncoding.
