12:46 <antocuni> so, I just pushed the branch "exceptval", which uses -1 to signal exceptions for functions which return pointers

12:47 <antocuni> but benchmarks don't show any performance improvement

12:47 <antocuni> which is a bit weird given that using this shortcut for malloc seems to give ~5-7%, but still

14:52 <mattip> antocuni: across the board all the benchmarks were "the same" (for some measure of same)?

14:52 <mattip> That might mean our non-jit performance has other bottlenecks

14:53 <antocuni> mattip: I just tried to run richards.py 100 (so it runs for ~20 seconds), and couldn't see any noticeable difference

15:56 <mattip> maybe one of the other benchmarks that allocate/release more objects would show a boost, like the templating ones

16:05 <antocuni> mattip: possibly, but when you run without JIT you are already allocating/releasing tons of objects for every line of python code

19:51 <cfbolz> hm, I also get "'remote repository changed while pushing - please try again'"

19:51 <cfbolz> anybody solved that?

19:52 <ronan> cfbolz: you need to update evolve, I think

19:55 <cfbolz> ronan: thanks, that worked indeed

19:55 <cfbolz> and it was faster, so good
