Redirecting stderr for extension modules

[Michael Pyle]

Hi Jeff,

Yep, we worked this one out after I sent the email and on Solaris everything
works a lot better. On Windows, however, nothing ever actually makes it into
the redirection file.

Just to reiterate a little, so the body of a finally is the absolute last
thing that is executed? Even after the return values are constructed in the
return statement?

Thanks.

Michael,
I think that what happens is that the return value (a tuple) is constructed
in the line
    return result, stderr
and then the body of the 'finally' is executed, setting stderr to a
different value.

You can write it this way (with the repeated 'if file: ...' block)

try:
    result = fn( *args, *kwds)
except:
    if file: ...
    raise
else:
    if file: ...
    return result, stderr
