0.2.2 ===== - expire time of None means "never expire". 0.2.1 ===== - Add new "nameregistry" helper. Another fixture derived from Beaker, this allows the ad-hoc creation of a new Dogpile lock based on a name, where all other threads calling that name at the same time will get the same Dogpile lock. Allows any number of logical "dogpile" actions to carry on concurrently without any memory taken up outside of those operations. - To support the use case supported by nameregistry, added value_and_created_fn to dogpile.acquire(). The idea is that the value_and_created_fn can return (value, createdtime), so that the creation time of the value can come from the cache, thus eliminating the need for the dogpile lock to hang around persistently. 0.2.0 ===== - change name to lowercase "dogpile". 0.1.0 ===== - initial revision.
