[New-bugs-announce] [issue26313] ssl.py _load_windows_store_certs fails if windows cert store is empty

[Jonathan Kamens]

New submission from Jonathan Kamens:

In ssl.py:

    def _load_windows_store_certs(self, storename, purpose):
        certs = bytearray()
        for cert, encoding, trust in enum_certificates(storename):
            # CA certs are never PKCS#7 encoded                                 
            if encoding == "x509_asn":
                if trust is True or purpose.oid in trust:
                    certs.extend(cert)
        self.load_verify_locations(cadata=certs)
        return certs

The line right before the return statement will raise an exception if certs is empty.

It should be protected with "if certs:" as it is elsewhere in this file.
