The latest Windows distribution of Python 2.4.2 is using the msvcrt71.dll, while PostgreSQL is using msvcrt.dll.
This lead to the following problem: I was using PyGreSQL to connect to the PostgreSQL database. There is a function that prints a query object q simply by writing: "print q". What happens on the lower levels is that PyObject_Print(q, stdout) is called, where stdout is the stdout file descriptor of msvcrt71.dll. Then, PyGreSQL calls the PostgreSQL function PQprint, handing it over that stdout file descriptor. PQprint in turn calls fprintf of msvcrt.dll, with the same file descriptor of msvcrt71.dll. This leads to a Windows exception since the file descriptors of mscvrt.dll and msvcrt71.dll are obviously not compatible. I can imagine that other C extensions which are using dlls based on msvcrt can run into the same problem. Is there a general strategy to avoid this kind of problems? -- Christoph -- http://mail.python.org/mailman/listinfo/python-list
