[Sugar-devel] FAQ on Sugarizer

At the cited meeting, I was prepared to update the status of activities
on ASLO and github. However, there was
A quick summary: There are 514 activities divided into three groups:
83 which have the current version from github installed on aslo
104 which are in github but not installed on aslo (and hence not
available to our users)
324 which are installed in ASLO but not in github
The primary problem with the 104 activities is the failure to update the
version number. This appears to result from an
erroneous instruction that the update to the version should be made by
the mythical maintainer. This is contrary to Sugar practice
over the past 10+ years. The practice has been for the
developer/maintainer to update the version number when releasing a change.
As an example, the version number of Turtle Blocks (Art) is 216. Only
the person making the changes knows when the implementation is
complete and ready for release and so must commit the version number change.
It would be a simple matter to update the version numbers (I have for
the school server aslolite). As a result, our users on Ubuntu may have
access to 187 activities.
It is amazing when we are worried about code coverage to find several
activities in github that do not have setup.py. Certainly, whoever is
posting changes to github can take the time to run python setup.py.
There were three activities where setup.py failed due to errors in po.
In two cases, the file contained duplicate entries - this was trivial to
fix. In another, setup.py crashed in genpot!
Along with wanting Music Blocks in Sugarizer, it would be nice to find
it in ASLO. Without a specific release, the user is left to find out
whether the current code is in a stable state. This, of course, is the
reason for version numbers. It separates tested releases from ongoing
A essential element of the github process is to mark versions as
released so that real maintainers can reproduce the environment in a bug
Reports from users would be more likely if they were given serious
attention instead of the normal handwaving. My report on the version
problem with HelloWorld - chosen as a simple example of the problem -
was to remove it from public view!
What we have needed for a long time is a system like the one Adam Holt
created at OLPC - a help at sugarlabs.org monitored by a volunteer team
that would respond and try to find a solution to the problems (support
