Skip tests for ldapsource with python >= 3.7
Until someone works on fixing these, this should make our CI green
again.
I tried to use setupModule() to check for python version, but
pre_setup_database() is apparently called even when a SkipTest exception
is raised there. So handle this in that method.
from __future__ import print_function
try:
rtype, = __args__
except ValueError:
print('USAGE: cubicweb-ctl shell <instance> detect_cycle.py -- <relation type>')
print()
graph = {}
for fromeid, toeid in rql('Any X,Y WHERE X %s Y' % rtype):
graph.setdefault(fromeid, []).append(toeid)
from logilab.common.graph import get_cycles
for cycle in get_cycles(graph):
print('cycle', '->'.join(str(n) for n in cycle))
