Added locking to Pyblosxom

Note: This is an old post in a blog with a lot of posts. The world has changed, technologies have changed, and I've changed. It's likely this is out of date and not representative. Let me know if you think this is something that needs updating.

I just added locking to Pyblosxom to allow separate Pyblosxom requests to synchronize on centralized data. In my case, the data is a file of how many views each of my blog entries has gotten. It seems to be pretty functional. It's something I had coded in my viewcounts plugin, but I've moved the code (and added to it) into the tools module so we can all use the same base.

An example of usage is this:

from Pyblosxom import tools

LOCKNAME = "viewcounts.dat"

lockret = tools.get_lock(request, LOCKNAME)
if lockret:
    # yay -- we have the lcok
    pass
else:
    # foo -- we don't have the lock
    pass


if tools.has_lock(request, LOCKNAME)
    # yay -- we have the lock
    pass
else:
    # foo -- we don't have the lock
    pass

tools.return_lock(request, LOCKNAME)

The code is in CVS. It'll go into the next version. Also, I added a unittest module to the code base.
