Comment (by atagar):
Thanks Tim. For other's reference
[https://github.com/teor2345/tor/commit/bfb49a here's the link].
Your generateFallbackDirLine.py looks good, but I'm unsure why you're
downloading the full consensus rather than just fetching this from the
server descriptor. Doing do does the same, is simpler, and runs far
faster.
Otherwise looks good to me!
{{{
#!/usr/bin/env python
# Generate a fallback directory whitelist/blacklist line for every
fingerprint
# passed as an argument.

# Usage:
# generateFallbackDirLine.py fingerprint ...

print('Usage: %s fingerprint ...' % sys.argv[0])
sys.exit(1)
fingerprint = sys.argv[1]
if not stem.util.tor_tools.is_valid_fingerprint(fingerprint):
print("'%s' isn't a valid relay fingerprint" % fingerprint)
try:
desc =
stem.descriptor.remote.get_server_descriptors(fingerprint).run()[0]
except urllib2.HTTPError as exc:
if exc.code == 404:
print('# %s not found in current consensus' % fingerprint)
sys.exit(1)
else:
raise
if not desc.dir_port:
print("# %s needs a DirPort" % fingerprint)
else:
ipv6_addresses = [(address, port) for address, port, is_ipv6 in
desc.or_addresses if is_ipv6]
ipv6_field = ' ipv6=[%s]:%s' % ipv6_addresses[0] if ipv6_addresses else
''
print('%s:%s orport=%s id=%s%s # %s' % (desc.address, desc.dir_port,
desc.or_port, fingerprint, ipv6_field, desc.nickname))
