Plone: checkinterval can't import pystone

Question

I found the hint about using checkinterval in the Plone documentation (for performance tuning) and tried to install it; in my buildout.cfg:

[buildout]
parts +=
    checkinterval

[checkinterval]
recipe = zc.recipe.egg
eggs =
    jarn.checkinterval

However, when I tried to call bin/checkinterval after building, it failed:

  File ".../eggs/jarn.checkinterval-1.0-py2.7.egg/jarn/checkinterval/checkinterval.py", line 4, in <module>
    from test import pystone
ImportError: cannot import name pystone

I had a look in the jarn.checkinterval package and found neither a test module nor any requirements specification.

I tried to add test to the parts list, and pip install test and the like; but the test package I found doesn't contain the string pystone.

So, where can I find this pystone utility, and how can I integrate it to have it found?

Or is this checkinterval thing outdated anyway?

Answer 1

Pystone should be in your python not your Plone. To check that just find out the python you are using & test the import as below:

$ head -2 bin/buildout
#!/home/daniel/dev/Plone/Development/myproject/bin/python

$ /home/daniel/dev/Plone/Development/myproject/bin/python
Python 2.7.5 (default, Jul 15 2013, 18:40:50) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from test import pystone
>>> 

Will probably fail on your system.

Which platform are you using? This fedora user's problem is similar to yours & is simply solved by yum install python-test. Hopefully it's that easy for you?

If you installed Plone using the Universal Installer it should have built you a python that (I think) would have dependencies like this included....
