Cygwin: Problem detecting subprocess termination after _spawn_posix in distutils?
by Steve Holden Aug. 21, 2007

Aug. 21, 2007

I've been trying to install PIL 1.1.6 for several days now under Cygwin. I have tried the Cygwin, Image and distutils lists with nary a pointer, so I wondered whether python-dev might lead me to an answer (other than "Stop using Cygwin" ;-) Here's the output from a failed setup run with a couple of debug prints inserted which should report how sub-process termination occurred - it hangs after this output. $ python setup.py build running build running build_py running build_ext building '… [View More]_imaging' extension SPAWN: ['gcc', '-fno-strict-aliasing', '-DNDEBUG', '-g', '-O3', '-Wall', '-Wstrict-prototypes', '-DHAVE_LIBZ', '-IlibImaging', '-I/usr/include', '-I/usr/include/python2.5', '-c', 'libImaging/Chops.c', '-o', 'build/temp.cygwin-1.5.24-i686-2.5/libImaging/Chops.o'] PATH? 1 V: 0 D:0 gcc -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -DHAVE_LIBZ -IlibImaging -I/usr/include -I/usr/include/python2.5 -c libImaging/Chops.c -o build/temp.cygwin-1.5.24-i686-2.5/libImaging/Chops.o Are we done yet? Waiting on pid 3280 I have to kill a python.exe process that's left running in the background if I CTRL/C the build. Otherwise it will spend all night in a tight loop. The compilation is finished when I kill the process, and the next compile will begin if I repeat the command. I extracted the _spawn_all function from distutils/spawn.py, hacked some exceptions and ran it under command line control. That worked fine with other subtasks, so I wondered whether this was a failure specific to gcc, which would seem kind of unlikely. I ran the same compile using my test function standing alone, seeing success: sholden@bigboy ~/Imaging-1.1.6 $ python ~/Projects/Python/spawntest.py gcc -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -DHAVE_LIBZ -IlibImaging -I/usr/include -I/usr/include/python2.5 -c libImaging/Chops.c -o build/temp.cygwin-1.5.24-i686-2.5/libImaging/Chops.o Are we done yet? Waiting on pid 3244 Got pid, status 3244 0 Got WIFEXITED 0 So it appears unlikely to be gcc-specific, leaving me wondering what exactly is the difference between the build environment and my tests. It would be really nice if test_distutils showed any failures, but it doesn't so any assistance would be welcome. At this point I can't even replicate the failure in a simpler test :-( regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 Holden Web LLC/Ltd http://www.holdenweb.com Skype: holdenweb http://del.icio.us/steve.holden --------------- Asciimercial ------------------ Get on the web: Blog, lens and tag the Internet Many services currently offer free registration ----------- Thank You for Reading ------------- [View Less]

Pythreads and BSD descendants
by Cameron Laird Aug. 4, 2007

Aug. 4, 2007

Folklore that I remember so unreliably I avoid trying to repeat it here held that Python threading had problems on BSD and allied Unixes. What's the status of this? I suspect the answer is, "Everything works, and the only real problem ever was that *signals* have different semantics under Linux and *BSD." Anyone who can answer explicitly, though, would repre- sent a help to me.

Python Package Index hostname change
by "Martin v. Löwis" Aug. 1, 2007

Aug. 1, 2007

The Python Packaging Index (the software formerly known as Cheeseshop) is now available at http://pypi.python.org/pypi The old addresses (www.python.org/pypi, and cheeseshop.python.org/pypi) will continue to work, either as aliases or using HTTP redirections. The software was renamed to its old name (PyPI - Python Package Index), as the Cheeseshop name was ever confusing people unfamiliar with British television comedy sketch (and puzzling even to people familiar with the sketch, as you *can*… [View More]

Extending Python by Adding Keywords & Data types
by Vishak Srinivas July 31, 2007

July 31, 2007

HI all, I am using python v2.5 and I am an amateur working on python. I am extending python for my research work and would like some help and guidance w.r.t this matter from you experienced python developers. II want to add some more KEYWORDS and DATATYPES into the python script apart from the existing ones. It would be really great if anybody could guide me as which files and modules I need to look to make these additions and enhancements to the existing python version. Thanks a lot in … [View More]

Re: [Python-Dev] [Python-3000] test_asyncore fails intermittently on Darwin
by Alan McIntyre July 30, 2007

July 30, 2007

Hasan, We made a change to bind the server to port 0, so that an unused port is selected for each test. I wasn't able to reproduce the failure after making this change; is the current trunk still failing for you?

Bus error in transformer.py
by Paul Colomiets July 28, 2007

July 28, 2007

Hi! I'm still working on bug: http://python.org/sf/1720241 First thing I've found is that `compile` works OK, but `compiler.parse` not. And I feel that It's bug in python, or python port, because I'm getting Bus error on some stage when I'm tracing execution and trying to backtrace. Also `parser.expr` passes ok, and error raises in Transformer class. I've attached part of the debugger session, and script I use. Any hints how to debug it further? -- Paul.
