I would suggest putting this common setup code into a _make_test_dir() helper function in regrtest, then have both regrtest and test.__main__ call it.

Change to the Distutils / Distutils2 workflow
by Tarek Ziadé 03 Dec '10

03 Dec '10

Hey We discussed with Eric about the debugging workflow and we agreed that our life would be easier if every bug fix would land first in Distutils2 when it makes sense, then get backported to Distutils1. For other core-devs that would mean that your patches should be done against hg.python.org/distutils2, which uses unittest2. Then Eric and I would take care of the backporting. I am planning to set up a wiki page with the workflow as soon as I get a chance. Thanks Tarek -- Tarek Ziadé | http://ziade.org

I would suggest being explicit here that "directory exists, but has a mode other than the one requested" always triggers an exception. Perhaps something like the following: "Raises an :exc:`OSError` exception if the target directory already exists, unless *exist_ok* is True and the existing directory has the same mode as is specified in the current call. Also raises an :exc:`OSError` exception if the directory cannot be created for any other reason." Cheers, Nick. -- Nick Coghlan | ncoghlan(a)gmail.com | Brisbane, Australia

FWIW, OSAF did a wrapping for Chandler, though I personally haven't used it: http://pyicu.osafoundation.org/ The README explains the mapping from the ICU APIs to Python ones, including iteration, string conversion, and timezone mapping for use with the datetime type. >-- >--Guido van Rossum (python.org/~guido) >_______________________________________________ >Python-Dev mailing list >Python-Dev(a)python.org >http://mail.python.org/mailman/listinfo/python-dev >Unsubscribe: >http://mail.python.org/mailman/options/python-dev/pje%40telecommunity.com

That Server 2008 build slave runs the test suite as administrator, so it was running that test and going into the os.link block, which it didn't do until r86733.

AIX 5.3 - Enabling Shared Library Support Vs Extensions

All, When I configure python to enable shared libraries, none of the extensions are getting built during the make step due to this error. building 'cStringIO' extension gcc -pthread -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -I/u01/home/apli/wm/GDD/Python-2.6.6/./Include -I. -IInclude -I./Include -I/opt/freeware/include -I/opt/freeware/include/readline -I/opt/freeware/include/ncurses -I/usr/local/include -I/u01/home/apli/wm/GDD/Python-2.6.6/Include -I/u01/home/apli/wm/GDD/Python-2.6.6 -c /u01/home/apli/wm/GDD/Python-2.6.6/Modules/cStringIO.c -o build/temp.aix-5.3-2.6/u01/home/apli/wm/GDD/Python-2.6.6/Modules/cStringIO.o ./Modules/ld_so_aix gcc -pthread -bI:Modules/python.exp build/temp.aix-5.3-2.6/u01/home/apli/wm/GDD/Python-2.6.6/Modules/cStringIO.o -L/usr/local/lib *-lpython2.6* -o build/lib.aix-5.3-2.6/cStringIO.so *collect2: library libpython2.6 not found* building 'cPickle' extension gcc -pthread -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I. -I/u01/home/apli/wm/GDD/Python-2.6.6/./Include -I. -IInclude -I./Include -I/opt/freeware/include -I/opt/freeware/include/readline -I/opt/freeware/include/ncurses -I/usr/local/include -I/u01/home/apli/wm/GDD/Python-2.6.6/Include -I/u01/home/apli/wm/GDD/Python-2.6.6 -c /u01/home/apli/wm/GDD/Python-2.6.6/Modules/cPickle.c -o build/temp.aix-5.3-2.6/u01/home/apli/wm/GDD/Python-2.6.6/Modules/cPickle.o ./Modules/ld_so_aix gcc -pthread -bI:Modules/python.exp build/temp.aix-5.3-2.6/u01/home/apli/wm/GDD/Python-2.6.6/Modules/cPickle.o -L/usr/local/lib *-lpython2.6* -o build/lib.aix-5.3-2.6/cPickle.so *collect2: library libpython2.6 not found* This is on AIX 5.3, GCC 4.2, Python 2.6.6 I can confirm that there is a libpython2.6.a file in the top level directory from where I am doing the configure/make etc Here are the options supplied to the configure command ./configure --enable-shared --disable-ipv6 --with-gcc=gcc CPPFLAGS="-I /opt/freeware/include -I /opt/freeware/include/readline -I /opt/freeware/include/ncurses" Please guide me in getting past this error.

Deprecating undocumented, unused functions in difflib.
by Terry Reedy 02 Dec '10

02 Dec '10

Difflib.SequenceMatcher object currently get two feature attributes: self.isbjunk = junk.__contains__ self.isbpopular = popular.__contains__ Tim Peters agrees that the junk and popular sets should be directly exposed and documented as part of the api, thereby making the functions redundant. The two functions are not currently documented (and should not be now). A google codesearch of 'isbjunk' and 'isbpopular' only returns hits in difflib.py itself (and its predecessor, ndiff.py). It would be easiest to just remove the two lines above. Or should I define functions _xxx names that issue a deprecation warning and attach them as attributes to each object? (Defining instance methods would not be the same). There is only one internal use of one of the two functions which is easily edited. -- Terry Jan Reedy
