Python infrastructure

• http://infra.psf.io/

• https://status.python.org/ Status of services maintained by the Python infra team

• https://github.com/python/psf-chef/

  • doc/nodes.rst

  • doc/roles.rst

• https://github.com/python/psf-salt/

• PSF pays a full-time sysadmin to maintain the Python infra: XXX

• https://www.python.org/psf/league/

• Managed services: http://infra.psf.io/overview/#details-of-various-services

• http://www.pythontest.net/ used by the test suite, see https://github.com/python/pythontestdotnet/

Services used by unit tests

• pythontest.net services:

  • pythontestdotnet: source of pythontest.net (resources used for Python test suite).

  • test_urllib2net: http://www.pythontest.net/index.html#frag, tcp/80 (HTTP)

  • FTP: ftp://www.pythontest.net/README

  • Copies of unicode text files like http://www.pythontest.net/unicode/EUC-CN.TXT

  • test_hashlib test files like http://www.pythontest.net/hashlib/blake2b.txt

  • test_httplib: self-signed.pythontest.net, tcp/443 (HTTPS)

  • test_robotparser: http://www.pythontest.net/elsewhere/robots.txt

  • test_socket: испытание.pythontest.net

• snakebite.net:

  # Testing connect timeout is tricky: we need to have IP connectivity
  # to a host that silently drops our packets.  We can't simulate this
  # from Python because it's a function of the underlying TCP/IP stack.
  # So, the following Snakebite host has been defined:
  blackhole = resolve_address('blackhole.snakebite.net', 56666)
  
  # Blackhole has been configured to silently drop any incoming packets.
  # No RSTs (for TCP) or ICMP UNREACH (for UDP/ICMP) will be sent back
  # to hosts that attempt to connect to this address: which is exactly
  # what we need to confidently test connect timeout.
  
  # However, we want to prevent false positives.  It's not unreasonable
  # to expect certain hosts may not be able to reach the blackhole, due
  # to firewalling or general network configuration.  In order to improve
  # our confidence in testing the blackhole, a corresponding 'whitehole'
  # has also been set up using one port higher:
  whitehole = resolve_address('whitehole.snakebite.net', 56667)
  

• news.trigofacile.com:

  • Used by test_nntplib

  • NNTP (tcp/119) and and NNTP/SSL (tcp/563)

  • Server administrator: julien@trigofacile.com

• ipv6.google.com:

  • test_ssl uses it to test IPv6: HTTP (tcp/80) and HTTPS (tcp/443)

• sha256.tbs-internet.com:

  • test_ssl uses it to test x509 certificate signed by SHA256: HTTPS (tcp/443)
