Software-update: Python 2.5 RC2

Python is een object geörienteerde programmeertaal waarmee simpele tot complexe platform-onafhankelijke applicaties kunnen worden ontwikkeld. Voor een handleiding gericht op beginners kan je op deze pagina terecht. Deze taal wordt door veel bedrijven gebruikt waar onder Industrial Light & Magic, Google en NASA. De ontwikkelaars hebben onlangs de tweede release candidate van Python 2.5 uitgebracht. De lijst met aanpassingen ziet er als volgt uit:

What's New in Python 2.5 release candidate 2?

Core and builtins:

• Make _PyGILState_NoteThreadState() static, it was not used anywhere outside of pystate.c and should not be necessary.
• Bug #1551432: Exceptions do not define an explicit __unicode__ method. This allows calling unicode() on exceptions classes directly to succeed.
• Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack. Also make sure that every exception class has __module__ set to 'exceptions'.
• Bug #1550983: emit better error messages for erroneous relative imports (if not in package and if beyond toplevel package).
• Overflow checking code in integer division ran afoul of new gcc optimizations. Changed to be more standard-conforming.
• Patch #1541585: fix buffer overrun when performing repr() on a unicode string in a build with wide unicode (UCS-4) support.
• Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
• The return tuple from str.rpartition(sep) is (tail, sep, head) where head is the original string if sep was not found.
• Bug #1520864: unpacking singleton tuples in list comprehensions and generator expressions (x for x, in ... ) works again. Fixing this problem required changing the .pyc magic number. This means that .pyc files generated before 2.5c2 will be regenerated.

Library:

• Reverted patch #1504333 because it introduced an infinite loop.
• Patch #1553314: Fix the inspect.py slowdown that was hurting IPython & SAGE by adding smarter caching in inspect.getmodule().
• Fix missing import of the types module in logging.config.
• Patch #1550886: Fix decimal module context management implementation to match the localcontext() example from PEP 343.
• Bug #1541863: uuid.uuid1 failed to generate unique identifiers on systems with low clock resolution.
• Bug #1543303, patch #1543897: remove NUL padding from tarfiles.
• Bug #1531862: Do not close standard file descriptors in subprocess.

Extension Modules:

• Fix bugs in ctypes:
  • anonymous structure fields that have a bit-width specified did not work
  • cast function did not accept c_char_p or c_wchar_p instances as first arg
• Bug #1551427: fix a wrong NULL pointer check in the win32 version of os.urandom().
• Bug #1548092: fix curses.tparm seg fault on invalid input.
• Bug #1550714: fix SystemError from itertools.tee on negative value for n.
• Fixed a few bugs on cjkcodecs:
  • gbk and gb18030 codec now handle U+30FB KATAKANA MIDDLE DOT correctly.
  • iso2022_jp_2 codec now encodes into G0 for KS X 1001, GB2312 codepoints to conform the standard.
  • iso2022_jp_3 and iso2022_jp_2004 codec can encode JIS X 0213:2 codepoints now.

Tests:

• Fix bsddb test_basics.test06_Transactions to check the version number properly.

Documentation:

• Bug #1541682: Fix example in the "Refcount details" API docs. Additionally, remove a faulty example showing PySequence_SetItem applied to a newly created list object and add notes that this isn't a good idea.

Tools:

• Bug #1546372: Fixed small bugglet in pybench that caused a missing file not to get reported properly.

Build:

• Patch #1540470, for OpenBSD 4.0.
• Patch #1545507: Exclude ctypes package in Win64 MSI file.
• Fix OpenSSL debug build process.

C API:

• Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro so it can be used as an expression.

En W3C, Feedvalidator, zo zijnen nog wel oneindig veel dingen te verzinnen

Jup, zelfs in Battlefield 2 zijn er Python scriptjes terug te vinden.
