to do something that the datastore API only allows in .84 and later

the code or not. Failing that, if I could detect the version of Sugar
and base my code on that that would be OK. I'm looking for something
robust and future-proof.
Any ideas? Thanks again,
What about calling the mounts() method in the DS dbus service and
compare what it returns in 0.84 and what earlier?
In 0.84 and later we have this stub:

Your suggestion was right on the money. When I run a simple program
from Terminal that prints out the files it finds it goes through my SD
card (also mounted on /media) and seems to stall in the depths of the
.olpc_store directory. What I think I need to do is write my own
walk-like function that ignores hidden directories. I really should
have thought of your suggestion myself but everything ran so well on
my test boxes that I jumped to the conclusion that something on the XO

Re: [Sugar-devel] Read-only access to thumb drive forbidden by Rainbow?
You can isolate Rainbow by disabling it and seeing if the problem goes away.
sudo rm /etc/olpc-security
will disable Rainbow
sudo touch /etc/olpc-security
will reenable it.

As I have mentioned in this list before, I am trying to make View
Slides able to get pictures that may or may not be in the Journal and
add them to a slide presentation. Under .82 objects in thumb drives
can be listed using the Data Store API, which was fine. In .84 you
cannot do that any more, but I was led to believe that if I just
wanted to READ these files that Python IO would work. So I use this
code:
valid_endings = ('.jpg', '.jpeg', '.JPEG', '.JPG', '.gif',
'.GIF', '.tiff', '.TIFF', '.png', '.PNG')
for dirname, dirnames, filenames in os.walk('/media'):
for filename in filenames:
if filename.endswith(valid_endings):
iter = self.ls_right.append()
jobject_wrapper = JobjectWrapper()
jobject_wrapper.set_file_path(os.path.join(dirname, filename))
self.ls_right.set(iter, COLUMN_IMAGE, filename)
self.ls_right.set(iter, COLUMN_PATH, jobject_wrapper)
Now this code runs just fine on the Sugar test environment of Fedora
11 (.84) and Fedora 10 (.82). However, if I try running the same code
on my XO, currently running .82, the Activity does not even finish
coming up. Using the Log Activity does not give me any useful
messages. I can only suspect that Rainbow is the culprit here,
although I'm not getting any actual messages that say that. It's just
a guess on my part.
In the code above the jobject_wrapper is a class I created so that my
table column could hold an object that would return a file path,
either by getting it from a wrapped journal object or from a path
supplied by the code above. Works fine in my test environment, but
bails out on my XO.
Does anyone have any ideas? Thanks,
James Simmons
