in latest Py3k site.py: configparser.NoSectionError: No section: 'posix_prefix'
by Stefan Behnel 20 May '11

20 May '11

Hi, since May 19, I get the exception below in the latest py3k site.py when trying to run a distutils build with it (building Cython). The changelog since the previous (working) CPython build is here: https://sage.math.washington.edu:8091/hudson/job/py3k-hg/374/ The failing build is here: https://sage.math.washington.edu:8091/hudson/job/cython-devel-build-py3k/13… This is on 64bit Linux. I tried with a clean checkout, no difference. Is this problem obvious to someone, is there anything that needs adaptation on our side (I hope not), or should I file a bug report? Thanks, Stefan """ $ python setup.py bdist --formats=gztar --cython-profile Traceback (most recent call last): File "/.../python/lib/python3.3/configparser.py", line 842, in items d.update(self._sections[section]) KeyError: 'posix_prefix' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/.../python/lib/python3.3/site.py", line 537, in <module> main() File "/.../python/lib/python3.3/site.py", line 522, in main known_paths = addusersitepackages(known_paths) File "/.../python/lib/python3.3/site.py", line 263, in addusersitepackages user_site = getusersitepackages() File "/.../python/lib/python3.3/site.py", line 238, in getusersitepackages user_base = getuserbase() # this will also set USER_BASE File "/.../python/lib/python3.3/site.py", line 228, in getuserbase USER_BASE = get_config_var('userbase') File "/.../python/lib/python3.3/sysconfig.py", line 576, in get_config_var return get_config_vars().get(name) File "/.../python/lib/python3.3/sysconfig.py", line 472, in get_config_vars _init_posix(_CONFIG_VARS) File "/.../python/lib/python3.3/sysconfig.py", line 324, in _init_posix makefile = get_makefile_filename() File "/.../python/lib/python3.3/sysconfig.py", line 318, in get_makefile_filename return os.path.join(get_path('stdlib'), config_dir_name, 'Makefile') File "/.../python/lib/python3.3/sysconfig.py", line 436, in get_path return get_paths(scheme, vars, expand)[name] File "/.../python/lib/python3.3/sysconfig.py", line 426, in get_paths return _expand_vars(scheme, vars) File "/.../python/lib/python3.3/sysconfig.py", line 142, in _expand_vars for key, value in _SCHEMES.items(scheme): File "/.../python/lib/python3.3/configparser.py", line 845, in items raise NoSectionError(section) configparser.NoSectionError: No section: 'posix_prefix' """

Python 2.6.7 release candidate 2 now available
by Barry Warsaw 20 May '11

20 May '11

Hello to all you Pythoneers and Pythonistas, I'm happy to announce the availability of Python 2.6.7 release candidate 2. Release candidate 1 was not widely announced due to a mismatch between the Mercurial and Subversion branches. Barring any unforeseen issues, this will be the last release candidate before 2.6.7 final, which is currently scheduled for June 3, 2011. As previously announced, Python 2.6 is in security-fix only mode. This means that general bug fix maintenance has ended, and only critical security fixes are supported. We will support Python 2.6 in security-fix only mode until October 2013. Also, this is a source-only release; no installers for Windows or Mac OS X will be provided. Please download and test this release candidate. http://www.python.org/download/releases/2.6.7/ The NEWS file contains a list of changes since 2.6.6. http://www.python.org/download/releases/2.6.7/NEWS.txt Many thanks go out to the entire Python community for their contributions great and small. Enjoy, -Barry (on behalf of the Python development community)

Don't set local variable in a list comprehension or generator
by Victor Stinner 19 May '11

19 May '11

Hi, ''.join(c for c in 'abc') and ''.join([c for c in 'abc']) do create a temporary c variable. In this case, the variable is useless and requires two opcodes: STORE_FAST(c), LOAD_FAST(c). The variable is not available outside the list comprehension/generator. I would like to remove the variable in these cases to speed up (micro-optimize!) Python. Remove the variable breaks code using introspection like: list([locals()['x'] for x in range(3)]) We may detect the usage of introspection (I don't know how hard it is), only optimize trivial cases (like "x for x in ..."), or only optmize with Python is running in optimize mode (python -O or python -OO). What do you think? Is it useless and/or stupid? I heard about optimization in the AST tree instead of working on the bytecode. What is the status of this project? Victor

Some Macs have case-sensitive file systems, and some people use case-sensitive file systems on various flavors of UNIX.

Overall I think it boils down to a cosmetic change that I'm not sure we need to make, which could unnecessarily break people's work. -1

Equality testing
by Ethan Furman 18 May '11

18 May '11

In Python 3 inequality comparisons became forbidden. --> 123 < [1, 2, 3] Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unorderable types: int() < list() However, equality comparisons are still allowed --> 123 == [1, 2, 3] False But you can't mix them (inequality wins) --> 123 <= [1, 2, 3] Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unorderable types: int() <= list() I realize this is probably a Py4000 change if it happens at all, but does this make sense? Shouldn't an attempt to compare to unlike objects be a TypeError, just like trying to order them is? It bit me when I tried to compare a byte string element with a single character byte string (of course they should have matched, but since the element was an int, the match was not longer True). ~Ethan~
