Announcing the release of SortedContainers version 1.4.2
What is SortedContainers? -------------------------
SortedContainers is an Apache2-licensed, pure-Python implementation of sorted list, sorted dict, and sorted set data types that is fast-as-C implementations with 100% code coverage and hours of stress testing. The project is fully documented with performance benchmarks and comparisons to alternative implementations.
What's new in 1.4.2? --------------------
* Updated docs to warn against editing sorted containers during iteration. Don't do it. * Updated SortedList* comparisons to match Sequence comparison as described in CPython Language Reference Section 5.9. https://docs.python.org/2/reference/expressions.html This also lead to the discovery of a bug in the blist.sortedlist implementation (filed as Issue #77 in their bug tracker). https://github.com/DanielStutzbach/blist/issues/77 * Updated SortedSet comparison to raise NotImplemented on type mismatch. * Bug Fix: Fixed reference to self._dict in sorteddict.ValuesView.count. * Bug Fix: SortedSet.__ior__ now calls `update` rather than `union`. * Improved performance of SortedList.__getitem__ by 35% for head and tail indexing. * Improved performance of SortedList.pop by 35% by inlining fast-paths of internal indexing methods. * Improved performance of `del sorted_list[:]` by simply calling `clear`. * Improved performance of `sorted_list[:] = values` by simply calling `clear` then `update`. * Updated SortedListWithKey to inherit directly from SortedList. Removed redundant methods. Merged sortedlistwithkey.py into sortedlist.py. * Updated SortedList to accept a key-argument callable that will dynamically return a SortedListWithKey instance. * Added new __init__ benchmark comparison. SortedContainers is generally 5-10x faster than other implementations. * Added reference to ruamel.ordereddict.sorteddict on performance comparison page at http://www.grantjenks.com/docs/sortedcontainers/performance.html * Removed SortedList._slice in favor of slice.indices. * Removed SortedList.as_list in favor of `list(sorted_list)`. * Updated benchmarks using CPython 2.7.10 and CPython 3.4.3. See docs for complete version strings. * Added CPython 3.5 runtime to test frameworks configs. * Added docs reference to Debian distributions at python-sortedcontainers and python3-sortedcontainers.
