For the record I haven't seen the eventlet greendns fixes you mentioned, and swift-dispersion-report is also broken in Bullseye due to this bug (cfr #989600) ___ Python-modules-team mailing list Python-modules-team@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/python-modules-team

I disagree in the sense that I don't think the package(s) currently are fit for release, but it isn't my call either. > FYI, since some fixes in Eventlet, OpenStack now works... Though the > Eventlet greendns API shall still be fixed. Do you have pointers to these fixes I could look at? I ran into this bug while testing Swift on Bullseye, specifically container-reconciler + memcache_servers with hostnames doesn't seem to work for me (while using ip addresses does work). best, Filippo ___ Python-modules-team mailing list Python-modules-team@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/python-modules-team

I very much think this bug should be RC: unless I'm missing something the
code below doesn't work but should:
$ python3 -c 'from eventlet.green import socket ;
print(socket.getaddrinfo("debian.org", 443))'
