Which version of Python are you using?

Ah should have seen it in the path. I'm having trouble reproducing it though...

Any ideas?

[shazow]

Ah, just noticed you meant the error happens on import, not install. Checking.

[shazow]

Hmm, seems to work during import too:

oh i know, i check this
it's just because i used eventlet.import_patched
urllib3 = eventlet.import_patched('urllib3')
from urllib3 import HTTPSConnectionPool

but with version 1.2.2 this will be fine

[shazow]

Ah, that is indeed a problem. Any interest in fixing it? :)

I was hoping to have exceptions available under urllib3.exceptions without an extra import if possible.

[MOON-CLJ]

ok i'll try to do this

from urllib3 import exceptions
Traceback (most recent call last):

ImportError: cannot import name exceptions

after viewing the source code of eventlet
i think this is just a eventlet.import_patched bug(as shown above)
but i still dont know exactly where is the bug in eventlet
i'll check it again later

if you have times, you can check this
https://bitbucket.org/which_linden/eventlet/src/a60be8a9cdb5/eventlet/patcher.py

if you find what causes this,
please let me know
thanks in advance

urllib3 version 1.2.2

Python 2.7.2+ (default, Oct  4 2011, 20:03:08)

after import urllib3
some attributes were lost

[shazow]

Hmm, here's the set difference:

['_collections',
 'request',
 'connectionpool',
 'filepost',
 'poolmanager',
 'exceptions',
 'packages',
 'response']

[MOON-CLJ]

it's not necessary to use eventlet.import_patched('urllib3')(but the bug is existed exactly)
eventlet.patcher.monkey_patch() can patch all the modules that eventlet can provide
so
eventlet.patcher.monkey_patch()
import urllib3
it will work for me
