Hi!
It seems using socket module patched by gevent lib makes PyDev test runner
dysfunctional.
PyDev test runner uses xmlrpclib (which in turn uses httplib, which in turn
uses socket). Running any test where socket is patched by gevent makes test
runner fail with "NotImplementedError: gevent is only usable from a single
thread".
Below is a "test case" and output.
In case someone knows how to handle this I would gladly hear the solution.
[code]from gevent import monkey
monkey.patch_all(socket=True, # socket=False makes PyDev test runner run ok
dns=True, time=True, select=True, thread=True,
os=True, ssl=True, httplib=False, aggressive=True)
import gevent
import unittest
def gevent_spawn():
def f(x):
print "f: ", x
greens = [gevent.spawn(f, x) for x in range(4)]
gevent.joinall(greens)
class Test(unittest.TestCase):
def test(self):
gevent_spawn()
if __name__ == '__main__':
gevent_spawn()[/code]
OUTPUT
[code]pydev debugger: starting
Finding files... done.
Importing test modules ... done.
