After upgrading from ZOBD3.9 to ZODB3.10 I couldn't connect to the ZEO server:

I confirm that the bug exists: I believe it was introduced with the
patch adding IPV6 support.
The patch looks good to me. Any tests probably belongs in
'src/ZEO/
is factored in such a way as to make reusing it for a non-TCP connection
difficult.

Also note that non-TCP tests need to be ommitted on windows.

For windows I guess I could handle the AttributeError exception that would be raised zrpc.client.
I also saw that in order to test the unix sockets properly I would have to do some changes start_zeo_server in ZEO/tests/forker.py to support addresses of unix sockets.
Alternatively I could monkey patch the address of an already created TCP server ZEO server in ZEO/tests/
Let me know what would you like to do about that and I will give it a try.

I wasn't expecting you to make a windows error sane in this case.
That would be nice, but a bonus. :) If you do this, then
we'd need a windows test, which would be hard for you to
debug.

If you use forker. I'm not sure that's necessary.
You could probably just instantiate a StorageServer
instance in a thread.

I don't really follow this.

It would probably be easier (for both of us) for me to fix this. :)
If you want to get involved in ZEO development
and want a learning opportunity, I'm happy work with you.
Let me know.

For now I won't go for the bonus points. I've added to my TODO list to
setup a windows virtual machine and write an exception for UNIX domain
sockets in windows. I'll have more time next week.

OK, I'll start simple:

I think it's a great opportunity. I could spend ~1 hour every day like
I'm doing these days but I don't know if my programming level will be
good enough for ZEO development with just 1 hour per day. I will
surely try.
Let me know if there is any other bug or something else you'd like me
to have a look at.

This patch introduces Bug #1004513.
I didn't include the tests in the patch because I don't know where to write it. If you give me a hint I can try.
