It is worth pointing out that until I can get a functioning python
client to a riak instance (eg known version of a client that works
with
a known version of the server) then the riak functionality is totally
broken :)
Anyone know (or can point to) a set of replicable install steps to
achieve this?
I used the latest riak 0.12 binary (osx-i386).
I didn't have any success with the PyPi version of protobuf, despite
it being spec'd in riak-python-client's setup.py, it kept failing to
import google.protobuf.
Compile and install the full protobuf-2.3.0 library [1] (a vanilla "./
configure" worked fine for me) and then install the protobuf Python
library from the code in the "python" subdirectory with a standard
"python setup.py install".
Set RIAK_TEST_HOST so that it matches that of the IP address setting
of one of the nodes in the cluster (for the Hudson build below, I'm
using a node hosted on a rackspace cloud server).
Hudson checkout, build and nosetests of riak-python-client:
http://bel-epa.com/hudson/job/riak-python-client/lastBuild/console
Caveat: 43 tests, 2x2 failures, one pair for each transport type. They
may be critical failures as they involve map-reduce and sibling-count
tests. But it's a start.
I'm as yet unfamiliar with the workings of riak but basic stuff works:
>>> from riak import *
>>> client = RiakClient(host='192.168.0.2')
>>> bucket = client.bucket("foo")
>>> obj = bucket.new("some_key", {"key":"value"})
>>> obj.store()
<riak.riak_object.RiakObject object at 0x7c9330>
>>> objval = bucket.get("some_key")
>>> objval.get_data()
{u'key': u'value'}
