[Sugar-devel] Activity Versioning - Dotted Scheme

A problem with introducing dotted version numbers is that Sugar
versions 0.82-0.86 parse the activity version field using the Python
>>> a = int('100.3')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: invalid literal for int() with base 10: '100.3'
If we introduce periods into activity version strings, Sugar will
throw a MalformedBundleException when parsing activity.info. The
effect would be that Sugar would simply fail to register the activity;
it would not appear in the Home view etc.
So, introducing period syntax into an activity bundle automatically
makes it incompatible with Sugar versions 0.82 - 0.86.
This is too harsh for me, so like Gary I would just keep using integers.

Has anyone looked into what would be needed to just make Browse work
with older versions of Hulahop?
Anecdote: My XO ran out of space over Thanksgiving and automatically
deleted Browse at boot time. I downloaded the latest version, but it
failed to launch as my XO is running the OLPC 8.2.0 build. This was
pretty annoying to me as I didn't have a web browser available to go
find out which version *would* work.

+1 to keeping activity version numbers totally separate from SP version.

I support this - ASLO works well enough that Fructose isn't strictly needed.
