Announcing the release of DiskCache version 2.0.2 What is DiskCache? ----
[DiskCache][1] is an Apache2 licensed disk and file backed cache library, written in pure-Python, and compatible with Django. By leveraging a rock-solid database library and memory-mapped files, cache performance can match and exceed industry standard solutions. There’s no need for a C compiler or running another process. [Performance is a feature][2] and testing has 100% coverage with unit tests and hours of stress in production.

Significant performance improvements were observed with many concurrent processes. http://www.grantjenks.com/docs/diskcache/djangocache-benchmarks.html * Add atomic increment and decrement methods: incr and decr. http://www.grantjenks.com/docs/diskcache/api.html#diskcache.Cache.incr * Add atomic method "add" for setting non-existant items. http://www.grantjenks.com/docs/diskcache/api.html#diskcache.Cache.add * Add method "read" like "get" but returns open file handle. http://www.grantjenks.com/docs/diskcache/api.html#diskcache.Cache.read * Add methods to create and drop tag index to evict items by tag. http://www.grantjenks.com/docs/diskcache/tutorial.html#cache * Cache and FanoutCache now support iteration. http://www.grantjenks.com/docs/diskcache/api.html#diskcache.Cache.__iter__ * FanoutCache and DjangoCache methods support "retry" parameter for timeouts. http://www.grantjenks.com/docs/diskcache/tutorial.html#djangocache * Use reset method to update settings rather than setting attributes. http://www.grantjenks.com/docs/diskcache/api.html#diskcache.Cache.reset * BugFix: The size of small bytes objects was double-counted. * BugFix: FanoutCache now uses "size_limit / shards" to limit shard volume. * BugFix: Changing "cull_limit" to zero will now only disable culling. * BugFix: Allow binding "close" and "clear" as signal handlers. * Re-run benchmarks and update tables and graphs. * Many documentation improvements and more examples. Features ---- * Pure-Python * Fully Documented * Benchmark comparisons (alternatives, Django cache backends) * 100% test coverage * Days of stress testing in production * Performance matters * Django compatible API * Thread-safe and process-safe * Supports multiple eviction policies (LRU and LFU included) * Keys support “tag” metadata and eviction * Developed on Python 2.7 * Tested on CPython 2.7, 3.4, 3.5 and PyPy Links ---- - Documentation: http://www.grantjenks.com/docs/diskcache/ - Download: https://pypi.python.org/pypi/diskcache - Source: https://github.com/grantjenks/python-diskcache - Issues: https://github.com/grantjenks/python-diskcache/issues Please upgrade. -- https://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
