Comment 3 for bug 1849971

I had the same idea about multiple shutdowns, but in my test that didn't trigger any exception. I also tried UNIX domain sockets to see if they behaved differently perhaps, but no. At least not in the super simple test below.

$ cat sock.py
import socket

s = socket.socket(socket.AF_UNIX, -1, -1, None)
print(s)
s.shutdown(socket.SHUT_WR)
s.shutdown(socket.SHUT_RDWR)
s.shutdown(socket.SHUT_RDWR)
$ python3.7 sock.py
<socket.socket fd=3, family=AddressFamily.AF_UNIX, type=SocketKind.SOCK_STREAM, proto=0>
$

I am currently running all tests again, but with the sock.shutdown() simply commented out. On first sight, it seems unneeded just before close(). The test results look much better now. I'm down to 2 errors and 2 failures, some of those probably because I use a boring old C locale instead of UTF-8.

How do I find which compiled extensions are failing? Bazaar already reported that as a problem, but I've never seen the root cause of it, so far. I am aware that I don't have the launchpadlib installed (there was no pkgsrc package for it yet, and it seemed to be used only in tools/check-newsbugs.py which is not installed.
