Thanks for replying Anatolly,
I'm 0-2 on it crashing on other peoples machines.
I have it doing the identical thing on 2 machines, one of which is
using python 2.5 and django svn. The other is using python 2.6 and
django svn. Both are using the 1.2 series of memcached and I have
tried using both python-memcache and cmemcache for the bindings. The
two machines I am having problems on are Ubuntu 9.04 and whatever
webfaction is running on.
After installing cmemcache I end up with an error while running
test.py file...
======================================================================
FAIL: test_memcache (__main__.TestCmemcache)
----------------------------------------------------------------------
Traceback (most recent call last):
File "test.py", line 254, in test_memcache
self._test_base(cmemcache, cmemcache.StringClient(self.servers),
ok=1)
File "test.py", line 132, in _test_base
self.failUnlessEqual(len(stats), 1)
AssertionError: 0 != 1
----------------------------------------------------------------------
Ran 1 test in 0.556s
FAILED (failures=1)
which someone else seemed to run into on this post
http://ubuntuforums.org/archive/index.php/t-1044135.html
Even with the test failing I was able to drop into the shell and test
both cmemcache and python-memcach manually and they seemed to be
operating correctly. Plus if instead of caching the querysets I cache
the list version all is well.
So I'm stumped at the cause.
Thanks for taking a look.
