authnzerver.cache module

This contains functions to drive the cache.

authnzerver.cache.cache_add(key, value, timeout_seconds=0.3, expires_seconds=None, cache_dirname='/tmp/authnzerver-cache')

This sets a key to the value specified in the cache.

authnzerver.cache.cache_decrement(key, timeout_seconds=0.3, cache_dirname='/tmp/authnzerver-cache')

This decrements the counter for key.

authnzerver.cache.cache_delete(key, timeout_seconds=0.3, cache_dirname='/tmp/authnzerver-cache')

This sets a key to the value specified in the cache.

authnzerver.cache.cache_flush(timeout_seconds=0.3, cache_dirname='/tmp/authnzerver-cache')

This removes all keys from the cache.

authnzerver.cache.cache_get(key, timeout_seconds=0.3, cache_dirname='/tmp/authnzerver-cache')

This sets a key to the value specified in the cache.

authnzerver.cache.cache_getrate(key, timeout_seconds=0.3, cache_dirname='/tmp/authnzerver-cache')

This gets the rate of increment for the key by looking at the time of insertion inserted at key and the number of times it was incremented in key-counter. The rate is then:

key-counter_val/((time_now - time_insertion)/60.0)

authnzerver.cache.cache_increment(key, timeout_seconds=0.3, cache_dirname='authnzerver-cache')

This sets up a counter for the key in the cache.

Sets the key -> time of initial insertion Then increments ‘key-counter’.

authnzerver.cache.cache_pop(key, timeout_seconds=0.3, cache_dirname='/tmp/authnzerver-cache')

This sets a key to the value specified in the cache.
