This occurs quite frequently now. In the latest build four bots
show this error.

If one changes the stacklevel in the DeprecationWarnings in the library to '2' instead of '1' (I believe it should be '2'), then an interesting array of deprecation warnings are issued...including from cookiejar code.

Most of them are in the urllib2 tests, though, and obviously they aren't being correctly protected.

I'm not sure what is causing the deprecation test to sometimes succeed and sometimes fail, though.  Running python -m unittest.test_urllib2 consistently fails for me without the 1->2 change, and consistently passes (but with more warnings) with it.

Running test_http_cookiejar and test_urllib2 in succession always
fails here. The same thing occurs when running test_urllib2

$ ./python -m test test_http_cookiejar test_urllib2
[1/2] test_http_cookiejar
[2/2] test_urllib2
test test_urllib2 failed -- Traceback (most recent call last):

1 test OK.
1 test failed:

How about silencing the AssertionError until a better solution
is found? The patch works here.
msg157994 - (view) Author: Antoine Pitrou (pitrou) * (Python committer) Date: 2012-04-10 22:47
Well, the point of the test is to check that the warnings are issued, so silencing them kind of defeats it.
Senthil, why did you use check_warning instead of assertWarns?

New changeset 751c7b81f6ee by Senthil Kumaran in branch 'default':
use assertWarns instead of check_warnings - Issue14341

Hi Antoine, 

I saw that check_warnings was commonly used ( and perhaps I had used to earlier without any problems) and overlooked assertWarns. But I think, it is good to remove support.check_warnings dependency here and just use assertWarnings.  Let me see if this squashes that sporadic failures in builldbots.

I think, the test_http_cookiejar and test_urllib2 dependency (if any) should also be looked at irrespective of this. I shall check that.
