| MasterDuke34 | what causes indirect name lookups? | 13:34 | |
| vrurg | MasterDuke34: like self."$method"()? | 13:36 | |
| MasterDuke34 | hm, that's the same as ::()? | 13:37 | |
| vrurg | No, it only traverses MRO. | ||
| MasterDuke34 | github.com/rakudo/rakudo/blob/mast...#L216-L279 is what i'm curious about | 13:38 | |
| vrurg | But then I don't really get your question. | ||

| vrurg | I see it used in Actions and Ops. Gimme a sec... | 13:39 | |
| term:sym<name> is using it. Doc phaser. require. Likely more, if you search by make_indirect_lookup method references. | 13:42 | ||
| MasterDuke34 | gitlab.com/jjatria/raku-game-entit...ng-loops.t causes 22k calls to INDIRECT_NAME_LOOKUP | 13:43 | |
| oh, ^name() perhaps | 13:44 | ||
| vrurg | I'd rather suspect @components. .^name should only result in a method lookup. | 13:47 | |
| jjatria is very interested in this | 13:48 | ||
| MasterDuke34 | jjatria: do you need the gather/takes? those are pretty slow | 13:49 | |
| btw, profiles show your short test file causing 850k deoptimizations, and the long one causing 300k deopts | 13:51 | ||
| jjatria | No, I can do away with them. I wasn't aware they'd be a bottleneck | ||
| vrurg | Last note and back to the main job. I think the most likely cause is token variable -> Actions method variable. | 13:52 | |
| jjatria | My optimisation game in Raku is weak, I was mostly focused on getting it to run, and then to get it to run fast enough. But if it can be faster, I'm very keen | ||

| rakudo: 3b7fef2e7d | (Stefan Seifert)++ | 2 files Speed up setup of NativeCall subs and reduce memory usage When replacing a native sub's stub body with a generated one, we need to remove the scheduled fixups, lest they undo our replacement. The easiest way to do this is to just run the compiler thunk, which takes care of this after dynamic compilation. This however is a very expensive operation as it not only compiles that body but has to create setup code for the lexical scope. This makes ... (6 more lines) |

| lizmat | hmmm.. make spectest failed on 2 files, but these run fine by themselves | 21:22 | |
| [Coke] | we don't have modules.raku.org setup here with Geth, I guess. | 21:28 | |

| vrurg | lizmat: I think they're flappers after all. | 22:06 | |
| lizmat | can't remember having these flap, though :-( | ||
| didn't flap when I bumped NQP either | |||
| vrurg | It's just my experience. Most of the time if something fails when is ran in a bunch but not individually – try it 50+ times and it eventually reveal a problem. | 22:11 | |

| vrurg | I just've pulled the master, t/spec/S17-supply/syntax-nonblocking-await.t fails under spectest. Trying it in a loop. | 22:19 | |
| lizmat | I've just reverted 3b7fef2e7de6bb915da0 locally, then will start a spectest run and look at the result tomorrow& | 22:20 | |
