This is a refactor of everything web2py uses with redis.
Specifically:
- a refactored redis_cache.py that fixes#958, allowing a "fail
gracefully" behaviour in case redis is not available
- a refactored redis_session.py that blocks less with with_lock=True
(although still not optimal)
- a new (and NEEDED) redis_utils.py that serves as the base for
everything else, allowing an RConn object that you can freely use as a
redis.StrictRedis connection, and that you can override in case you're
using a different library (or that web2py will use in case redis-py
won't be the de-facto standard around)
- a newly - and much anticipated - redis_scheduler.py. It's a slip-in
replacement for the standard scheduler that uses redis for workers
coordination. Feel free to dig in the code and improve it.
For redis_cache and redis_session changes are BREAKING. It means that
users will need to change the import locations and tune a bit the code.
Now every module depends on an gluon.contrib.redis_utils.RConn object
(or similar) that in turns is very similar to a redis.StrictRedis one.
The redis instance is EXTERNAL to the modules themselves (no more "host,
port, db, password" parameters in RedisCache or RedisSession)
