BTrees 4.3.1

4.3.1 (2016-05-16)

• Packaging: fix password used to automate wheel creation on Travis.

4.3.0 (2016-05-10)

• Fix unexpected OverflowError when passing 64bit values to long keys / values on Win64. See: https://github.com/zopefoundation/BTrees/issues/32

• When testing PURE_PYTHON environments under tox, avoid poisoning the user’s global wheel cache.

• Ensure that he pure-Python implementation, used on PyPy and when a C compiler isn’t available for CPython, pickles identically to the C version. Unpickling will choose the best available implementation. This change prevents interoperability problems and database corruption if both implementations are in use. While it is no longer possible to pickle a Python implementation and have it unpickle to the Python implementation if the C implementation is available, existing Python pickles will still unpickle to the Python implementation (until pickled again). See: https://github.com/zopefoundation/BTrees/issues/19

• Avoid creating invalid objects when unpickling empty BTrees in a pure-Python environment.

• Drop support for Python 2.6 and 3.2.

4.2.0 (2015-11-13)

• Add support for Python 3.5.

4.1.4 (2015-06-02)

• Ensure that pure-Python Bucket and Set objects have a human readable __repr__ like the C versions.

4.1.3 (2015-05-19)

• Fix _p_changed when removing items from small pure-Python BTrees/TreeSets and when adding items to small pure-Python Sets. See: https://github.com/zopefoundation/BTrees/issues/13

4.1.2 (2015-04-07)

• Suppress testing 64-bit values in OLBTrees on 32 bit machines. See: https://github.com/zopefoundation/BTrees/issues/9

• Fix _p_changed when adding items to small pure-Python BTrees/TreeSets. See: https://github.com/zopefoundation/BTrees/issues/11

4.1.1 (2014-12-27)

• Accomodate long values in pure-Python OLBTrees.

4.1.0 (2014-12-26)

• Add support for PyPy and PyPy3.

• Add support for Python 3.4.

• BTree subclasses can define max_leaf_size or max_internal_size to control maximum sizes for Bucket/Set and BTree/TreeSet nodes.

• Detect integer overflow on 32-bit machines correctly under Python 3.

• Update pure-Python and C trees / sets to accept explicit None to indicate max / min value for minKey, maxKey. (PR #3)

• Update pure-Python trees / sets to accept explicit None to indicate open ranges for keys, values, items. (PR #3)

4.0.8 (2013-05-25)

• Fix value-based comparison for objects under Py3k: addresses invalid merges of [OLI]OBTrees/OBuckets.

• Ensure that pure-Python implementation of OOBTree.byValue matches semantics (reversed-sort) of C implementation.

4.0.7 (2013-05-22)

• Issue #2: compilation error on 32-bit mode of OS/X.

• Test PURE_PYTHON environment variable support: if set, the C extensions will not be built, imported, or tested.

4.0.6 (2013-05-14)

• Changed the ZODB extra to require only the real ZODB package, rather than the ZODB3 metapackage: depending on the version used, the metapackage could pull in stale versions of this package and persistent.

• Fixed Python version check in setup.py.

4.0.5 (2013-01-15)

• Fit the repr of bucket objects, which could contain garbage characters.

4.0.4 (2013-01-12)

• Emulate the (private) iterators used by the C extension modules from pure Python. This change is “cosmetic” only: it prevents the ZCML zope.app.security:permission.zcml from failing. The emulated classes are not functional, and should be considered implementation details.

• Accomodate buildout to the fact that we no longer bundle a copy of ‘persistent.h’.

• Fix test failures on Windows: no longer rely on overflows from sys.maxint.

4.0.3 (2013-01-04)

• Added setup_requires==['persistent'].

4.0.2 (2013-01-03)

• Updated Trove classifiers.

• Added explicit support for Python 3.2, Python 3.3, and PyPy. Note that the C extensions are not (yet) available on PyPy.

• Python reference implementations now tested separately from the C verions on all platforms.

• 100% unit test coverage.

4.0.1 (2012-10-21)

• Provide local fallback for persistent C header inclusion if the persistent distribution isn’t installed. This makes the winbot happy.

4.0.0 (2012-10-20)
