[14:58] <agronholm> thanks
[15:06] <jimbaker> in https://bitbucket.org/jimbaker/jython-resource-leaks, i have removed all classes of resource leaks (to be verified more exhaustively, this is just applying code patterns) other than mutable public statics, as seen in PySystemState
[15:07] <jimbaker> one thing in particular is that ThreadStateMapping is implemented as weakkey/weakvalue concurrent map, courtesy of guava MapMaker
[15:09] <jimbaker> but since this slows things down a bit (about 15% on the pystone test, perhaps the one case where pystone is useful), i removed the use of recusion_limit checking, since this is something we get for free from the JVM anyway. sys.getrecursionlimit/sys.setrecursionlimit then become no-ops
[15:11] <jimbaker> (if we do restore this checking, we should follow what pypy has done and only make it approximate, by doing it PyBaseCode/PyTableCode, and not every __call__ receiver implementation)
[15:12] <jimbaker> with this change pystone is back to what we currently see
[15:13] <jimbaker> pjenvey, any thoughts from the pypy perspective?

[20:01] <pjenvey> jimbaker - definitely want the JVM to do those checks if possible, though I remember adding a recursion limit check in the past for a test
[20:01] <pjenvey> don't really remember why it was necessary now
[20:02] <jimbaker> pjenvey, we definitely should support setting/getting, just a question of whether it's a no-op or not
[20:04] <jimbaker> however, we may want to check call depth anyway, so we can support http://bugs.jython.org/issue2142 - this would be nice to have, it just needs to be cleared out to avoid class loader leaks
[20:05] <jimbaker> so i'm thinking of supporting a hybrid solution, again at the callsite, not the receiver. let's see if i can make that work in practice
[20:27] * whg is now known as zz_whg
[21:51] <jimbaker> ok, i restored the recursion depth tracking as part of a general hybrid solution to add ThreadState as a thread local. so now getting 180373 pystones/second in my best run, about 10000 more than the approach in trunk
[21:51] <jimbaker> (pystone is a good test for this sort of thing)
[21:52] <jimbaker> (incidentally cpython 2.7 does 113480 pystones/second on my machine, a one year-old retina mac book pro. this is not a good way to compare, but hey look at how much better we are doing on this one test ;)
[21:53] <jimbaker> this also adds support for setting the class loader per thread to imp.getSyspathJavaLoader(), and should reliably clean it up, because of the call depth tracking
[22:20] <OmegaPhil> cool
