| 18:35:34 |  headius | I'm working on AOT...first trying to get a grip on how much ovrehead is currently involved in deserializing IRScope |
| 18:36:02 | headius | tricky bit seems like it's going to be getting the IRScope instances in a place where the bytecode can see them |
| 18:36:19 | headius | enebo: what's the status of your branch at this point? It may be a better place for me to work from |
| 18:36:39 |  enebo | I have to walk out the door |
| 18:36:44 | headius | ok |
| 18:36:47 | headius | we'll talk later |
| 18:37:07 | enebo | but you can look at it jit_irscope_removal |
| 18:37:19 | headius | ok |
| 18:39:41 | headius | running a bench deserializing erb.rb looks like it's sub-ms times very quickly |
| 18:44:08 | headius | yeah this is tricky...persisted IR and AOT bytecode both have their own tree of scopes and they need to know about each other |
| 18:46:12 | headius | perhaps the IRScopes could be deserialized along with method handles to point at their JVM version |
| 18:47:25 | headius | need to look at branch for a bit |
| 18:51:02 | headius | https://gist.github.com/headius/cf8af0793c7ca3e04211589b4d279421 |
| 18:52:32 | headius | hmmm |
| 18:53:01 | headius | if JVM compiler mapped scopes to method names in the resulting output it should be possible to inject those handles when deserializing |
| 22:46:31 |  lopex | numbers? |
| 22:46:42 | headius | soon perhaps! |
| 22:47:00 | lopex | w00t |
| 22:50:49 | lopex | I hope not many unstable 2.7 changes get adopted soon |
| 22:52:39 | lopex | thankfully ruby never made the python 2.7 mistake |
| 22:52:56 | lopex | headius: right ? |
| 22:53:25 | headius | what's the python 2.7 mistake? |
| 22:53:44 | lopex | headius: splitting the versions basically |
| 22:53:56 | lopex | which hampered adoption |
| 22:54:30 | lopex | keeping 2.7 so long slowed down 3.x |
| 22:55:20 | lopex | they're passed that point, but that's what it was |
| 22:56:24 | headius | 1.9 was really the big move, and 1.8.7 was a bad attempt to bridge the gap |
| 22:56:27 | headius | in Ruby |
| 22:56:54 | lopex | yea, it was never the case in ruby |
| 22:57:09 | lopex | even if it might seem so |
