  • Python 2.0

    ...release candidate 1 (since beta 2)? What is release candidate 1? We believe that release candidate 1 will fix all known bugs that we intend to fix for the 2.0 final release. This release should be a bit more stable than the previous betas. We would like to see even more widespread testing before the final release, so we are producing this release candidate. The final release will be exactly the same unless any show-stopping (or brown bag) bugs are found by testers of the release c...

    ...candidates stepping forward, in addition to the 8 incumbents. We have a total of 12 candidates for Director this year, but currently the Board is limited to 8 Directors. As Tim Peters put it, "the bigger the board, the more gets done." This motion aims to increase the limit on the number of Directors going forward. We learned in the past that it's better to expand the Board than to miss out on offers of help. This does not mean that all candidates for Director will automatically be...

    ...release candidate 3? Release date: 20-Nov-2008 Core and Builtins Issue #4349: sys.path included a non-existent platform directory because of a faulty Makefile. Issue #3327: Don't overallocate in the modules_by_index list. Issue #1721812: Binary set operations and copy() returned the input type instead of the appropriate base type. This was incorrect because set subclasses would be created without their __init__() method being called. The corrected behavior brings sets into line with lists an...

    ...released. This release promised better object oriented capabilities, and the time was right for Rackspace to dedicate more people to the project. The system was totally redesigned from the ground up, including new database schemas and application design strategies. At this time we re-dubbed the project "CORE," an acronym for Core Objects Reused Everywhere, in order to reflect the overall design goal for CORE: modularity and reusability across all systems in the company. With that goal ...

    ...released and was an important building block for my developments. For the low-level part, Fortran 77 was eliminated because of its archaic character, lack of memory management, and portability issues in C-Fortran interfacing. C++ was a candidate, but ultimately not chosen because portability between compilers was still an issue in 1996, and because I considered the benefits of C++ for the small amount of compiled code in the project insufficient to compensate for the complexity of the language. ...

  • Notes

    ...release another release candidate. The list here is the complete list of patches (except version updates): Core Tim discovered a nasty bug in the dictionary code, caused by PyDict_Next() calling dict_resize(), and the GC code's use of PyDict_Next() violating an assumption in dict_items(). This was fixed with considerable amounts of band-aid, but the net effect is a saner and more robust implementation. Made a bunch of symbols static that were accidentally global. Build and Ports The setup.p...

    ...release the "import lock": imp.acquire_lock() and imp.release_lock(). Note: this is a reentrant lock, so releasing the lock only truly releases it when this is the last release_lock() call. You can check with imp.lock_held(). (SF bug #580952 and patch #683257.) Change to cPickle to match pickle.py (see below and PEP 307). Fix some bugs in the parser module. SF bug #678518. Thanks to Scott David Daniels, a subtle bug in how the zlib extension implemented flush() was fixed. Scott...
