Hi folks: Sometimes, my Pharo images grows a lot. Size like 80MB or
similar. Marcelo Cortez gave me a couple of changes (fileouts) that
make my images go back to their original size or similar. For
example, it was tasted in a 87 MB and after this changes and this
stuff, it become in 24 MB. The same with another one from 65M to 35M.
If you have a big Pharo image, save a copy and do this tests:
1) File in all the changes I attach.
There is nothing attached.
2) Go to a workspace and evaluate:
OBDPAbstract reinitAllCache.
LocalSends allInstances first initialize.
EventManager resetMap.
Smalltalk garbageCollect.
Did this make your image too much smaller?
When I evaluate SystemNavigation default obsoleteBehavio size I
get a a number of 3 digits.
Perhaps it is a matter with the OB. I guess it generates dependences
while you are developing a class and it creates on the fly an
obsolteClassXXX when there is something that doesn't exist. Then
they are processes and they are never garbage collected.
When SmalltalkImage tries to fix the obsoletes delegates to the
literal frames of the compiled methods so that to search references
to the obsoletes. But references were not gone because they weren't
garbage collected. The same method finishes with error if the
obsoletes > 0.
Does anyone has a comment for this?
Well, the only comment I have is that this procedure should go on the
snippets page no the Pharo Project website. I know you are after a
deeper fix, but others will have to provide that, as this is way over
my head at this time.
I tried to do my best to write in English from what Marcelo told me
and from what I can understand from the changesets.
You did a good job, I understand the problem conceptually from your
description. I just don't have any idea how to fix that.
Best,
