New submission from ariel-wikimedia:
With python 2.7.5 (running on fedora 20 with all updates), socket.getaddrinfo
for a hostname such as 836937931829 will fail. Docker produces these sorts of
hostnames (really random hex strings, but some hex strings only contain digits
0-9).
How to reproduce:
Add the lines
172.17.10.53 blobber
172.17.10.54 836937931829
to /etc/hosts
run the following:
import socket
print socket.getaddrinfo('172.17.10.53',80,socket.AF_INET,0,socket.SOL_TCP)
print socket.getaddrinfo('blobber',80,socket.AF_INET,0,socket.SOL_TCP)
print socket.getaddrinfo('172.17.10.54',80,socket.AF_INET,0,socket.SOL_TCP)
print socket.getaddrinfo('836937931829',80,socket.AF_INET,0,socket.SOL_TCP)
Expected output:
[(2, 1, 6, '', ('172.17.10.53', 80))]
[(2, 1, 6, '', ('172.17.10.53', 80))]
[(2, 1, 6, '', ('172.17.10.54', 80))]
[(2, 1, 6, '', ('172.17.10.54', 80))]
Actual output:
[(2, 1, 6, '', ('172.17.10.53', 80))]
[(2, 1, 6, '', ('172.17.10.53', 80))]
[(2, 1, 6, '', ('172.17.10.54', 80))]
Traceback (most recent call last):
File "./test-getaddrinfo.py", line 6, in <module>
