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

With the latest Image (50651) and VM, the issue remains the same.
The most critical part for me is the fact that cleaning the image (at least 
using ImageCleaner) does not reduce its size.I have a commercial product with 
users already using it, who obtain the product by downloading. This issue 
causes my product to be at least double the size in total because of the image 
not being reduced, and sometimes more.

I have no idea how to help solve this issue, but if it remains once Pharo 5 is 
released next month, that means I won't be able to use it for my product, and I 
would be stuck with older versions where the cleaning process worked better.
Should I be addressing this issue in another list? Maybe vote up how critical 
it is in some pending bugs list somewhere?
Don't get me wrong, I love Pharo and all the community work being done. I love 
the fact that I can get a humble commercial product out to the users.I just 
think maybe other products are more server based and not affected by this 
issue, but for anyone creating products with Pharo that are to be downloaded by 
the customers it should be top priority.
Thanks for Pharo, and thanks for any help or guidance you may be able to 
provide on this matter.

 I've got some additional details.
Using the old VM at: 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 same ImageCleaner cleanUpForProduction, only this time is took about 
half an hour to do the same.
Hope that helps to catch the reason.Thanks

 Thanks for the reply Marcus.I just checked, and can confirm that the old 
process took only 2 minutes and converted a 58,2 MB image (includes Seaside and 
my web product) into a 26,4 MB production image.
By looking at PharoDebug.log, I can tell that this version is:
VM: Win32 - IX86 - 6.1 - NBCoInterpreter

Hope that helps. This is Pharo 5, so the Image Cleaner must have broken at some 
point after this version.
Let me know if there is any additional information I can provide to help figure 
it out.

 Hello,
Sorry for the late answer.
I think there are multiple problems…
1) slowness. 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 both….

Hi, and sorry if this has already been discussed.
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.
