Hello,

In a few hours old CVS checkout, I'm having problems getting the embedded python to work.

This is true even in non-embedded Python. Move away "_sre.pyd", and the interactive session shows:

'import site' failed; use -v for traceback

import re dir(re) ['builtins', 'doc', 'file', 'name', 'engine']

Running with "-v" shows:

'import site' failed; traceback: Traceback (most recent call last): File "E:\src\python-cvs\lib\site.py", line 298, in ? encodings._cache[enc] = encodings._unknown AttributeError: 'module' object has no attribute '_unknown'

So, my speculation at this point is that for some reason, site.py now depends on re, which depends on _sre - but somehow a "stale" import is left hanging around.

Another strange point - executing "python", then typing "import re" is completely silent, as we have noted. However, executing "python -c "import re" dumps an exception:

python -c "import re" 'import site' failed; use -v for traceback Traceback (most recent call last): File "E:\src\python-cvs\lib\warnings.py", line 270, in ? filterwarnings("ignore", category=OverflowWarning, append=1) File "E:\src\python-cvs\lib\warnings.py", line 140, in filterwarnings item = (action, re.compile(message, re.I), category, AttributeError: 'module' object has no attribute 'compile'

I'm really not sure what is going on here. I'd suggest creating a bug at sf.

Mark.
