Distinguishing system and user objects

Hi guys,

Given any Pharo image and a (any) package or class category, how do
you find if the package/class category belongs to the official image
release?
Thanks,

Hernán

In a pharo dev image there is a packages.txt that is generated in image
build time. It contains the list of packages that were added to a Pharo
Core image to create a Pharo Dev image.

I have been looking at the (horribly named) #timeStamp of methods; if my initials/name appear a substring, then it's a red flag that I might have written it, or at least want to be alerted that I might have unpackaged efforts.  The following is a first attempt at releasing the code I use to save a later load packages:

  http://squeaksource.com/PharoInbox/Migrate-Core-BillSchwab.2.mcz

It might not work w/o my stream extensions and other infrastructure - fair warning.  If remotely interested, look at the class comment of Migrate; expect to subclass it and override a few methods (#me, #homeGrownPackages) to get it to do anything meaningful.  This design allows me to distribute its core functionality but have my own concrete class that is not for public viewing.

The #suspectMethodsReport might be of interest to you.

In scriptLoader you get the list of all the core packages with version.
I will start to play with metacello to do that instead of doing everything :)

Thanks for the help guys.
Actually I thought of having something as simple as

aClass isSystemDefault

then having more control detecting changes (to system or user
objects). One may implement in a browser a Warning mode that
prevents/protect from mistakes, once I've implemented an extension
method in Behavior with the **same selector** of an existing method,
and the tools didn't helped me to detect it.

Another use case is for helping future tools to know which changes to track.

we could do it at the class level
I think that we should get some static metadata soon or later
