Pippy: Python path set improperly

[sascha_silbe]

The slideshow example in Pippy doesn't work:

Traceback (most recent call last):

File "/home/sugar/.sugar/default/org.laptop.Pippy/tmp/pippy_app.py", line 7, in <module>

from pippy import query

File "/home/sugar/sugar-jhbuild/install/share/sugar/activities/Pippy.activity/library/pippy/query.py", line 22, in <module>

from sugar.datastore import datastore

ImportError: No module named sugar.datastore

Which version of sugar-datastore are you using?

[sascha_silbe]

Everything built from sugar-jhbuild as of today.

[tomeu]

that module is in sugar-toolkit, wonder how pippy can start but that example cannot.

Are you running it after running './sugar-jhbuild shell'?

that module is in sugar-toolkit, wonder how pippy can start but that example cannot.

Is Pippy somehow fiddling with the Python search path?

"print sys.path" gives the following inside Pippy:

['/home/sugar/.sugar/default/org.laptop.Pippy/tmp', '/home/sugar/.sugar/default/org.laptop.Pippy/tmp', '/home/sugar/sugar-jhbuild/install/share/sugar/activities/Pippy.activity/library', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2', '/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload', '/usr/local/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages/Numeric', '/usr/lib/python2.5/site-packages/gst-0.10', '/var/lib/python-support/python2.5', '/var/lib/python-support/python2.5/gtk-2.0']

Inside "sugar-jhbuild shell" it is:

['', '/home/sugar/sugar-jhbuild/install/lib64/python2.5/site-packages/gtk-2.0', '/home/sugar/sugar-jhbuild/install/lib/python2.5/site-packages', '/home/sugar/sugar-jhbuild/install/lib64/python2.5/site-packages', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2', '/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload', '/usr/local/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages/Numeric', '/usr/lib/python2.5/site-packages/gst-0.10', '/var/lib/python-support/python2.5', '/var/lib/python-support/python2.5/gtk-2.0']

As you see, two paths below the sugar-jhbuild install directory are missing.

Are you running it after running './sugar-jhbuild shell'?

I'm running it from inside sugar-emulator. Is it possible to start Activities outside of sugar / sugar-emulator or did I misunderstand your question?

[sascha_silbe]

I've found the code and am actually surprised it would work on any system:

pippy_app.py:go_button_cb()

        self._pid = self._vte.fork_command \
                    (command="/bin/sh",
                     argv=["/bin/sh", "-c",
                           "python %s; sleep 1" % pippy_app_name],
                     envv=["PYTHONPATH=%s/library" % get_bundle_path()],
                     directory=get_bundle_path())

As you see it sets PYTHONPATH to a single directory. This will override the PYTHONPATH set by sugar-jhbuild. Only built-in (i.e. system) paths and the Pippy library path will work. That's why pippy, os, sys etc. can be used, but nothing from Sugar.

[sascha_silbe]

append original PYTHONPATH

[sascha_silbe]

With the patch, it loads fine. Complains about no photos being found (though I just downloaded one and verified the MIME type matched), but that should be a different issue.

[brian]

Will apply patch

[sascha_silbe]

Any news on this?
