Jeffrey Armstrong added the comment: I thought, while I'm here reporting another bug, I'd bump this once more. There is a patch here, and it corrects clearly broken code.

Zachary Ware added the comment: It's a simple enough fix, so I went ahead and committed it. Thanks for the patch! I've created issue24224 to track the addition of tests to test_msilib (for more than just this issue). -- resolution: fixed - stage: resolved - patch review status: closed - open ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21931 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Jeffrey Armstrong added the comment: There's not much to look into. If the Python function encounters an argument error, it returns an uninitialized integer as an error code.

[issue21931] Nonsense errors reported by msilib.FCICreate for bad argument
New submission from Jeffrey Armstrong: The function fcicreate in PC/_msi.c can return nonsense if the list of files passed to msilib.FCICreate does not contains tuples as expected. To replicate, import msilib msilib.FCICreate(test.cab, [entry.txt]) The above code will return a ValueError of the format: ValueError: FCI error 11260524 The error code is meaningless. If one were to examine the code, you can see in PC/_msi.c:246 (in current): if (!PyArg_ParseTuple(item, ss, filename, cabname)) goto err; If we look at the error handler at PC/_msi.c:262, it assumes that one of the Windows MSI API calls had failed, and will print the contents of the ERF error structure: err: PyErr_Format(PyExc_ValueError, FCI error %d, erf.erfOper); /* XXX better error type */ In the case where the list does not contain tuples, the value of erf.erfOper was never initialized or set because the error being raised is not due to the Windows MSI API. The error is highly misleading as it is simply an argument error. -- components: Extension Modules messages: 222458 nosy: Jeffrey.Armstrong priority: normal severity: normal status: open title: Nonsense errors reported by msilib.FCICreate for bad argument type: behavior versions: Python 3.4, Python 3.5 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue21931 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
