I just "upgraded" from M2Crypto 0.17 to M2Crypto 0.18, and I'm
running my regression tests. I'm seeing occasional cases where
M2Crypto raises the exception SSL.SSLError, and the associated
error is "(0, 'Error')", which is the bogus error you get if you feed 0 to
"perror". It failed once on "verisign.com"' s cert, then worked
on the next try.
This is on Windows, running Python 2.4 (which is what M2Crypto
supports on Windows.)
I'm trying to make this reproduceable. More later.

Still trying to reproduce this. Every time except the first,
the regression test passed. More later. Might be an uninitialized
variable in a DLL, or something like that.

Still having trouble reproducing the problem. But somewhere,
something raised that bogus no-error exception three times.
Anything that returns "(0, 'Error')" as exception data is a bug.

If you can, build python and m2crypto with debug symbols, and place
breakpoints in |case SSL_ERROR_SYSCA LL| blocks (from _ssl.i). Then rerun
the tests. That would be my first guess as to where these might be
coming from.

I don't have the right compiler to build it on Windows, and it
doesn't seem to be failing on Linux. It failed three times during
one test run and hasn't failed since. That makes me suspect an
uninitialized data problem in C code. I'll try to reproduce the
problem.

I'm unable to reproduce the problem at this time. Even re-installingM2Cry pto
doesn't make it recur. I've been rerunning my regression test
over and over, and it's not repeatable.
I suspect that for some reason Windows networking was generating
a local error, and the Windows error status to UNIX-like error status
conversion is wrong somewhere.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
