Voyage: how to delete references to objects.
by olivier April 18, 2014

April 18, 2014

Hi, I'm using Voyage in a Pharo application. I have two MongoDB collections which are ComicsCollection and ComicsBook. Each book is attached to a instance of ComicsCollection. The reference of each book is stored in an ordered collection (in the instance of ComicsCollection). The problem is that if I remove a book, the reference to the book is not deleted from ComicsCollection. How can I remove properly a book and the reference to the book ? Best regards Olivier ;-)

Hi, I'm using Voyage and I need to duplicate an existing document in a Mongo database. I suppose that the id must be changed before saving. What is the best way to do that ? Best regards Olivier ;-)

You might be much happier with your locks if you grab blocks of numbers at a time. Stephan

Spec: replace sub-widget
by Sean P. DeNigris April 12, 2014

April 12, 2014

I have a ComposeableModel, which contains another ComposeableModel: self instantiateModels: #( flashCardModel FeFlashCardUI). I want to refresh child and update the parent. Before doing "self buildWithSpec", - Replacing the child's model works: "flashCardModel model: self newFlashCard." - But replacing the whole child doesn't work: "flashCardModel := self newFlashCardUI." Why? What's the right way to handle this? Thanks. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Spec-replace-sub-widget-tp4754364.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

can we have the pharo theme back please?
by kmo April 12, 2014

The pharo theme seems to have been dropped from Pharo 3. I loved that theme. The first thing I always do is switch to the pharo theme. Is it still available somewhere? I really do not like the pharo 3 theme and the Watery and Vistary themes are no use on Linux. -- View this message in context: http://forum.world.st/can-we-have-the-pharo-theme-back-please-tp4753945.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Memory profiling: usage per class - instance in old memory
by Thomas Bany April 11, 2014

April 11, 2014

Hi, My app is a parser/filter for binary files, that produces a bunch of ascii files. At the begining of the parsing, the filtering step involves the storage of the positions of 32 objects, each second for a whole day. So that's 32 Arrays with 86400 elements each. During this step, the memory used by my image grows from 50Mb to ~500Mb. I find it far too large since I'm pretty sure my arrays are the largest objects I create and only weight something like 300kb. The profiling of the app shows that hte footprint of the "old memory" went up by 350Mb. Which I'm pretty sure is super bad. Maybe as a consequence, after the parsing is finished, the memory footprint of the image stays at ~500Mb What are the tools I have to find where precisely the memory usage explodes ? For example, is it possible to browse the "old memory" objects to see which one fails to get GC'ed ? Thanks in advance, Thomas.

Making a theme work consistently is a huge amount of work. We have not finished making one of them work. Iâm in favor of finishing one theme before spending time on other themeâs. Stephan

Hi all, I was wondering if there is an implementation of a hierarchical state machines (with input and output actions) available somewhere for Pharo. Any ideas?

Quit without asking to save
by Thomas Bany April 10, 2014

April 10, 2014

Hi ! I'm developping a desktop application for Windows and I want to prevent the user from saving the image. First off, setting the #canSaveImage permission to false does not seems to prevent saving. But it's okey since the user won't have access to the World Menu. However, upon quitting the VM, a dialog pop up asking if I want to quit the image without saving. Is it possible to remove it ? Thanks in advance, Thomas.
