Logged In: YES user_id=86216 Hmm...was someone looking over my shoulder? Guess what I was investigating before I broke for New Years? $ python /usr/lib/python2.3/test/regrtest.py -l test_os test_os test test_os failed -- Traceback (most recent call last): File "/tmp/python.280/usr/lib/python2.3/test/test_os.py", line 50, in test_tmpfile IOError: [Errno 29] Illegal seek The good news is this problem is fixed in Cygwin CVS: http://cygwin.com/ml/cygwin-cvs/2003-q4/msg00076.html The bad news is I must rebuild against the next official Cygwin release (i.e. 1.5.6) before users can get this fix. Just dropping in the latest Cygwin snapshot will not work, because Cygwin's 64-bit I/O magic is resolved at link time not runtime. I will release a new Cygwin Python package ASAP after Cygwin 1.5.6 is released. BTW, doesn't it *always* work on Linux! :,)

Logged In: YES user_id=86216 I'm waiting for Cygwin 1.5.7, because 1.5.6 is too unstable. Sorry for the delay...

Logged In: YES user_id=86216 First Cygwin was unstable, then I became unstable... :,) Cygwin became stable (enough) again with version 1.5.9. Unfortunately, it was released right when I was switching jobs. Thanks for your patience.
