Pharo.ini access

by Robert Kuszinger

Hello Everyone! I wonder if there is a chance to access pharo.ini contents from inside the image I'm lazy and I'd like to add my own settings (new keys) to pharo.ini. It would be nice to have these once the image is started so I don't have to create my own .ini and parse it. So, is Pharo.ini key values are in the image in a class or somewhere? I'd like to add: gcDowloadDir = dirname gcODBCsource = DSN .... and so on :) thanks Robert

Probably now I can tell you that we lost some afternoons one trying the get a tick list to have multiple renaming on instance and we discovered that they were some problems in the models of RB. It was totally strange. Now a good cleaning of nautilus is still needed in this part of the code.

how to add a class via programatic refactoring

by Tudor Girba

Hi, I would like to create a class with instance variables and methods using RB, and preview the changes with the changes browser. I know how to create AddClass, AddInstanceVariable, AddMethod refactorings individually and query for their changes. For example: (RBAddClassRefactoring addClass: #SomeClass superclass: #Object subclasses: {} category: #Category) primitiveExecute; changes. (RBAddInstanceVariableRefactoring variable: 'x' class: #SomeClass) primitiveExecute; changes My question is: is it possible to create them all in one batch and preview their changes in one single window? Cheers, Doru -- www.tudorgirba.com www.feenk.com "If you interrupt the barber while he is cutting your hair, you will end up with a messy haircut."

I will integrate some of your additions in Pharo (the enhancing of API). Esteban this is just improving Spec API so it does not break anything.

Re: [Pharo-users] Windows headless and service

by Robert Kuszinger

Hello Everyone! I've tested NSSM successfully with manual service start and reboot/auto start as well. Details: Windows Server 2008 R2 64 bit. - *For the log: Pharo.exe --headless <image_name> does nothing. Executed from windows command line in the directory where Pharo is installed (actually, extracted)* - NSSM - full path to pharo exe - working directory is the path where Pharo.exe is put - parameter: name of production image pu in the same working dir - enable interaction with desktop (haven't tested without itt - all other options are default - Service appears on service list. Started well manually. - Seaside web server with installed app is alive and runs well - Service manual stop function works (actually, kills it, no problem, this is a stateless server holding only volatile session data thus no shutdown callback is necessary) That's all by far. This seems to be a 100% solution to run Pharo WWW server on Windows as a service. Thanks for the many ideas and support. Later on I may inform you on the results of real life situations (load, stability, etc).

Re: [Pharo-users] Image Cleaner no longer useful?

by Maximiliano Tabacman

I've got some additional details. Using the old VM at:Â http://files.pharo.org/vm/pharo/win/Pharo-VM-win-stable.zip I downloaded a fresh 50491 image at:http://files.pharo.org/image/50-preSpur/50491.zip Opened a playground and executedImageCleaner cleanUpForProduction This was really fast, and in 2 minutes the process was complete. Then I downloaded the 50492 image at:http://files.pharo.org/image/50-preSpur/50492.zip Did the sameÂ ImageCleaner cleanUpForProduction,Â only this time is took about half an hour to do the same.

This is strange that unloading packages is so slow. This looks like a bug to me. 2) image size in Pharo5: We have a bug right now that images *never* shrink. This means that if you savean image once with 80MB, even if the GC cleans up, the saved image stays 80MB. We should fix bothâ¦.

In Pharo 3, I used to be able to do: ImageCleaner cleanUpForProduction and that would correctly remove a lot of unneeded code in the image when preparing for a productive release.Then I would save the cleaned image, and since it had been cleaned, it would be smaller than the original development image (say from 60 mb to 25 mb).This process would take about 2-3 minutes. Then, in Pharo 4 it seems some changes were made here, since the same process took a lot more, like 20 minutes. When I first tried Pharo 5, I was happy to see that it was again down to 2-3 minutes. And here comes my question...Why is it that since some 2 months ago (maybe more), the Pharo 5 images once again require like 20 minutes to complete the cleanUpForProduction process? Also, and this is the most relevant to me, it no longer reduces the image size.So if I want to release a Pharo 5 version based on the latest images, I would be shipping a product that is more than twice the size of previous public versions of my software! Thanks for any insights into this. If it is a known bug, I would like to know if there is any workaround, or alternative objects that I should be using for the process.Also, if it would help for me to run any tests in particular to share and help in fixing this, please let me know.
