[Kevin Jacobs] > ... > Attached is a patch for this leak and several others in cPickle.c > ... Thanks, Kevin! THe patch was spot-on and I checked it in (and marked as a bugfix candidate since the same cPickle leaks appear to exist in 2.2.2). I already backported the tp_slot_hash leak fix to the 2.2 maintenance branch. I checked in the leak-detector code to test_both.py, so this will be easier to try the next time around. The remaining leaks in the C implementation were my errors, in the date and datetime pickle support functions. There are no visible leaks remaining in the Python or C implementations of the sandbox datetime code. BTW, running hefty tests in a loop and staring at sys.gettotalrefcount() each trip is, as I think this exercise demonstrated, a powerful leak detector. I think we plugged about 10 slow leaks here, 8 of them long-standing leaks in Python (of course, whether they're "slow" or "fast" leaks depends on the app! for the test suite, they were slow). Fun, fun <wink>.
