Parto Chobeiry added the comment: @neologix: I tried to patch socketserver.py from versions 2.7, 3.3 and 3.4 -- it fails all the time, slightly differing error messages but similar to this: u1@~/Projects$ patch <../Downloads/socketserver_use_selectors-1.diff can't find file to patch at input

Ronald Oussoren added the comment: You could trace using dtruss (as root), which behaves similarly to strace. What happens when you first set "http_proxy" in the environment: $ env http_proxy= python -m SimpleHTTPServer If that doesn't cause problems the hang is caused by the _scproxy extensio

Charles-François Natali added the comment: By the way, could you test with the patch available in issue #21040 ? It'll use poll() instead of select(): I don't think it'll fix your problem, but it'll be a nice test anyway :-) -- ___ Python tracker

Charles-François Natali added the comment: You could use tcpdump to see what's going on (does the server reply to SYN?). Note that it might very well be either a firewall setting, or a DoS protection (some sort of backoff when there are too many SYN within a short interval). -- nosy: +

Parto Chobeiry added the comment: I thought you were kidding concerning "print()" -- thus I started using "python -m trace -t httpd.py" >trace 2>&1. The hanging does not occur when tracing (however, things slow down immensely naturally)! When breaking the httpd.py while it is not serving anymo
