The new Lock object now checks the value_and_created_fn() + an extra time within the "lock acquired" phase so that multiple writers + who entered the block don't rely upon a memory-only version of creation + time. + + +.. changelog:: + :version: 0.3.3 + :released: Tue Sep 25 2012 + + .. change:: + :tags: + :tickets: + + repair setup.py so that tests don't install, + courtesy Ben Hayden. + +.. changelog:: + :version: 0.3.2 + :released: Wed Jun 13 2012 + + .. change:: + :tags: + :tickets: + + upgrade to beta. + +.. changelog:: + :version: 0.3.1 + :released: Sun Apr 15 2012 + + .. change:: + :tags: + :tickets: + + py3k compatibility is in-place now, no + 2to3 needed. + +.. changelog:: + :version: 0.3.0 + :released: Sat Apr 14 2012 + + .. change:: + :tags: + :tickets: + + Renamed the project again - to dogpile.core. + Package has been reorganized so that "dogpile" + is a pure namespace package. The base dogpile + features are now in "dogpile.core". + + +.. changelog:: + :version: 0.2.2 + :released: Fri Mar 30 2012 + + .. change:: + :tags: + :tickets: + + expire time of None means "never expire". + +.. changelog:: + :version: 0.2.1 + :released: Fri Dec 23 2011 + + .. change:: + :tags: + :tickets: + + 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. + + .. change:: + :tags: + :tickets: + + 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. + +.. changelog:: + :version: 0.2.0 + :released: Sun Oct 23 2011 + + .. change:: + :tags: + :tickets: + + change name to lowercase "dogpile". + +.. changelog:: + :version: 0.1.0 + + .. change:: + + initial revision.
