Changelog

4.5.0 (unreleased)

  • Fix the extremely rare potential for a crash when the C extensions are in use. See issue 21.

4.4.2 (2017-05-12)

  • Fixed C capsule name to fix import errors.
  • Ensure our dependencies match our expactations about C extensions.

4.4.1 (2017-05-04)

  • Fix C code under Python 3.4, with missing Py_XSETREF.

4.4.0 (2017-05-04)

  • Enable the C extension under Python 3.
  • Drop support for Python 3.3.

4.3.0 (2017-01-20)

  • Make tests compatible with ExtensionClass 4.2.0.
  • Drop support for Python 2.6 and 3.2.
  • Add support for Python 3.5 and 3.6.

4.2.2 (2015-05-19)

  • Make the pure-Python Acquirer objects cooperatively use the superclass __getattribute__ method, like the C implementation. See #7.
  • The pure-Python implicit acquisition wrapper allows wrapped objects to use object.__getattribute__(self, name). This differs from the C implementation, but is important for compatibility with the pure-Python versions of libraries like persistent. See #9.

4.2.1 (2015-04-23)

  • Correct several dangling pointer uses in the C extension, potentially fixing a few interpreter crashes. See #5.

4.2 (2015-04-04)

  • Add support for PyPy, PyPy3, and Python 3.2, 3.3, and 3.4.

4.1 (2014-12-18)

  • Bump dependency on ExtensionClass to match current release.

4.0.3 (2014-11-02)

  • Skip readme.rst tests when tests are run outside a source checkout.

4.0.2 (2014-11-02)

  • Include *.rst files in the release.

4.0.1 (2014-10-30)

  • Tolerate Unicode attribute names (ASCII only). LP #143358.
  • Make module-level aq_acquire API respect the default parameter. LP #1387363.
  • Don't raise an attribute error for __iter__ if the fallback to __getitem__ succeeds. LP #1155760.

4.0 (2013-02-24)

  • Added trove classifiers to project metadata.

4.0a1 (2011-12-13)

  • Raise RuntimeError: Recursion detected in acquisition wrapper if an object with a __parent__ pointer points to a wrapper that in turn points to the original object.
  • Prevent wrappers to be created while accessing __parent__ on types derived from Explicit or Implicit base classes.

2.13.9 (2015-02-17)

  • Tolerate Unicode attribute names (ASCII only). LP #143358.
  • Make module-level aq_acquire API respect the default parameter. LP #1387363.
  • Don't raise an attribute error for __iter__ if the fallback to __getitem__ succeeds. LP #1155760.

2.13.8 (2011-06-11)

  • Fixed a segfault on 64bit platforms when providing the explicit argument to the aq_acquire method of an Acquisition wrapper. Thx to LP #675064 for the hint to the solution. The code passed an int instead of a pointer into a function.

2.13.7 (2011-03-02)

  • Fixed bug: When an object did not implement __unicode__, calling unicode(wrapped) was calling __str__ with an unwrapped self.

2.13.6 (2011-02-19)

  • Add aq_explicit to IAcquisitionWrapper.
  • Fixed bug: unicode(wrapped) was not calling a __unicode__ method on wrapped objects.

2.13.5 (2010-09-29)

  • Fixed unit tests that failed on 64bit Python on Windows machines.

2.13.4 (2010-08-31)

  • LP 623665: Fixed typo in Acquisition.h.

2.13.3 (2010-04-19)

  • Use the doctest module from the standard library and no longer depend on zope.testing.

2.13.2 (2010-04-04)

  • Give both wrapper classes a __getnewargs__ method, which causes the ZODB optimization to fail and create persistent references using the _p_oid alone. This happens to be the persistent oid of the wrapped object. This lets these objects to be persisted correctly, even though they are passed to the ZODB in a wrapped state.
  • Added failing tests for http://dev.plone.org/plone/ticket/10318. This shows an edge-case where AQ wrappers can be pickled using the specific combination of cPickle, pickle protocol one and a custom Pickler class with an inst_persistent_id hook. Unfortunately this is the exact combination used by ZODB3.

2.13.1 (2010-02-23)

  • Update to include ExtensionClass 2.13.0.
  • Fix the tp_name of the ImplicitAcquisitionWrapper and ExplicitAcquisitionWrapper to match their Python visible names and thus have a correct __name__.
  • Expand the tp_name of our extension types to hold the fully qualified name. This ensures classes have their __module__ set correctly.

2.13.0 (2010-02-14)

2.12.4 (2009-10-29)

  • Fix iteration proxying to pass self acquisition-wrapped into both __iter__ as well as __getitem__ (this fixes https://bugs.launchpad.net/zope2/+bug/360761).
  • Add tests for the __getslice__ proxying, including open-ended slicing.

2.12.3 (2009-08-08)

  • More 64-bit fixes in Py_BuildValue calls.
  • More 64-bit issues fixed: Use correct integer size for slice operations.

2.12.2 (2009-08-02)

2.12.1 (2009-04-15)

  • Update for iteration proxying: The proxy for __iter__ must not rely on the object to have an __iter__ itself, but also support fall-back iteration via __getitem__ (this fixes https://bugs.launchpad.net/zope2/+bug/360761).

2.12 (2009-01-25)

  • Release as separate package.
