client doesn't recover after invalid argument in Redis.set()

[marw]

Following code does not work:

import redis.client
db = redis.client.Redis('localhost', 6379)
db.set("example","123")
True
try:
... db.set("invalid key","123")
... except Exception, e:
... print str(e)
...
wrong number of arguments for 'set' command
db.set("example","123")
Traceback (most recent call last):
...
File "<...>\redis\client.py", line 274, in _parse_response
raise ResponseError(response)
redis.exceptions.ResponseError: unknown command '123'

The same behavior is with Redis server 1.2.2 and 1.3.7

It restores its behaviour after you try set for one more time.
This problem is related to usage of inline protocol that should be ditched in favor of multi-bulk protocol.
As for now redis-py isn't binary-safe (i.e. you can't use spaces in keys).

And now, thanks for kmerenkov, redis-py is binary safe. Upgrade to b33a6fc and issue is resolved.

But now, this code doesn't raise error:
db.set("invalid key","123")

[andymccurdy]

That's because it isn't an error. Any character including spaces are valid in key names.
