Recently I moved the sessions from the database to Redis, and I'm wondering: is there a way to retrieve info about sessions when they are stored in Redis? For example, when sessions are stored in the database, you have the option to use SQL to do some stuff like counting or deleting sessions. How to do it when sessions are stored in Redis?
I also use Redis to cache HTML responses from web2py and any other stuff that can be cached (lists, dictionaries, etc). In order to be able to list the keys cached by one specific web2py application, I have written this custom function to retrieve those keys. I've read that it's not a good idea to use cache.redis.r_server.keys() method on production <https://stackoverflow.com/questions/23296681/redis-safely-retrieving-a-small-set-of-keys-in-production-database>, so I written this code based on what I saw in the clear() method at gluon.contrib.redis_cache <https://github.com/web2py/web2py/blob/master/gluon/contrib/redis_cache.py#L233> : def get_cache_keys(application, prefix=''): import re result =  regex = ':%s*' % prefix prefix = 'w2p:%s' % application cache_set = 'w2p:%s:___cache_set' % application r = re.compile(regex) buckets = current.cache.redis.r_server.smembers(cache_set) # get all buckets if buckets: # get all keys in buckets keys = current.cache.redis.r_server.sunion(buckets) else: return result for a in keys: if r.match(str(a).replace(prefix, '', 1)): result.append(a) return result With that code, I'm able to list all the keys cached by a web2py application. As I'm also using Redis to store sessions, I want to be able to list all the session keys. I've tried a similar code to the one showed above, replacing this: prefix = 'w2p:sess:%s' % application cache_set = 'w2p:sess:%s:id_idx' % application But that doesn't work. Is it possible to achieve what I want? Any suggestion will be much appreciated.
