Sun May 10 19:46:51 UTC 2015 - benoit.monin@gmx.fr
- update to version 4.0.9:
* Make the C and Python TimeStamp objects behave more alike
* Intern keys of object state in __setstate__ to reduce memory
usage when unpickling multiple objects with the same attributes
* Add support for PyPy3
* 100% branch coverage
- additional changes from version 4.0.8:
* Add support for Python 3.4
* In pure-Python Persistent, avoid loading state in _p_activate
for non-ghost objects (which could corrupt their state). (PR #9)
* In pure-Python, and don’t throw POSKeyError if _p_activate is
called on an object that has never been committed. (PR #9)
* In pure-Python Persistent, avoid calling a subclass’s
__setattr__ at instance creation time. (PR #8)
* Make it possible to delete _p_jar / _p_oid of a pure-Python
Persistent object which has been removed from the jar’s cache
(fixes aborting a ZODB Connection that has added objects).
(PR #7)
- additional changes from version 4.0.7:
* Avoid a KeyError from _p_accessed() on newly-created objects
under pure-Python: these objects may be assigned to a jar, but
not yet added to its cache. (PR #6)
* Avoid a failure in Persistent.__setstate__ when the state dict
contains exactly two keys. (PR #5)
* Fix a hang in picklecache invalidation if OIDs are manually
passed out-of-order. (PR #4)
* Add PURE_PYTHON environment variable support: if set, the C
extensions will not be built, imported, or tested
- update project URL
- point the source URL to pypi
- drop type-mismatch.patch: fixed upstream
- add fix_32-bit_timestamp_hashcode.patch: fix timestamp hash
computation on 32 bit platform
- pass -q to test to avoid spamming the build log
- rename CHANGES.txt and README.txt to CHANGES.rst and README.rst:
