| <xaxxon> | sparr, presumably you asked your question on ##javascript / |
| 02:13:02
| <caitp> | v8 is bsd licensed still right? or is it apache 2.0 like everything else now? |
| 02:15:58
| <caitp> | sparr: because, it (BSD)'s a pretty liberal license, you could probably fork v8 or use the extension API if you need it to do something special |
| 02:16:10
| <caitp> | apache 2.0 would probably still be fine too |
| 02:18:17
| <xaxxon> | someone once told me how to print out a v8::string in a debugger but I've since lost it :( anyone know how |
| 02:20:16
| <xaxxon> | p v8::internal::String::cast(*name)->ToAsciiArray() |
| 02:30:37
| <caitp> | that will do it for you, es |
| 02:30:37
| <caitp> | yes |
| 02:30:37
| <caitp> | I keep meaning to write lldb macros to make it easier to debug v8, but who has the time for that |
| 02:30:37
| <caitp> | especially when the lldb api is crap |
| 02:37:56
| <xaxxon> | caitp, what is your involvement with the v8 project? (I'm completely ignorant as to who is who.. you could be google's vp of internet technology and I'd have no idea) |
| 02:39:56
| <caitp> | I am a VP of technology at Alphabet and oversee the v8 project |
| 02:39:57
| <caitp> | just kidding |
| 02:40:28
| <caitp> | I work at Igalia as a contributor to v8 for some of our customers |
| 02:43:18
| <xaxxon> | ah, cool. |
| 02:48:06
| <caitp> | I've been working on it for a few years, implemented template strings as a starter project in.. 2014 or something? |
| 02:49:04
| <caitp> | more recently landed async functions, and have been trying to do a bunch to improve runtime performance, and fix bugs, and trying not to introduce too many new ones |
| 02:50:36
| <caitp> | and, pretty soon will be doing a lot more work poking at an embedded v8 project to improve performance any way I can. but for now, it's time for a glass of wine and a good book |
| 02:50:38
| <caitp> | ciao |

| <koldbrutality> | okay i found the work around but still bloated |
| 06:33:17
| <koldbrutality> | grrr it's still bugged between 5.1.200-5.3.332... i'm going to have to git bisect again |
| 06:44:54
| <xaxxon> | koldbrutality, what are you fighting with? |
| 06:47:55
| <koldbrutality> | i am trying to get x32 v8 so i can build x32 chromium. there is no jit javascript for any current web browser for this abi. |
| 07:38:51
| <xaxxon> | is the last version of 32-bit chrome that old? |
| 07:49:14
| <koldbrutality> | no it says 54 on their site |
| 07:50:41
| <koldbrutality> | that's for windows though |

| <caitp> | aklein: any chance of non-googlers ever being able to spawn jobs on the master.internal.client.v8 bucket? |
| 18:39:51
| <caitp> | particularly for try_perf |
| 18:41:05
| <caitp> | I think the Igalians mainly working on Blink have been able to spawn perf jobs on the builders they use for a long time, so it seems like it ought to be feasible |

| 19:03:31
| <aklein> | caitp: we have this problem where v8 has a single person responsible for all our infrastructure stuff, but yeah, that seems like it would be good |
| 19:03:47
| <aklein> | if you file a feature request on the v8 tracker I can make sure machenbach sees it |
| 19:09:48
| <aklein> | thanks! |
| 19:09:50
| <caitp> | filed, and you and machenbach are both CC'd |
| 19:15:37
| <aklein> | caitp: yep, my thanks was from seeing it :) |

| <sparr> | xaxxon__: yes, I did. I ended up having to play nasty tricks with Function.prototype to invade a scope I couldn't otherwise reach |
| 20:22:39
| <xaxxon__> | sparr, context? |
| 20:22:49
| <xaxxon__> | ahhh |
| 20:33:12
| <caitp> | what |
| 20:33:37
| <caitp> | "nasty tricks with Function.prototype to invade a scope..." it starts to sound interesting around there, could you provide details? |
| 20:43:49
| <bradleymeck> | caitp: override Object#{toString,valueOf} and since there is not true syntax for them Function#{bind,call,apply} |
| 20:44:13
| <bradleymeck> | then people randomly use .call and you can get a hold of things (especially fancy if you can start up a debugger) |
| 20:44:31
| <bradleymeck> | ive done it to get a hold of things in the wild before |
| 20:44:56
| <caitp> | but, what "things"? |
| 20:45:16
| <caitp> | what is being exposed that wasn't normally? is this a security vulnerability v8 should care about? |
| 20:45:21
| <bradleymeck> | mostly getting a hold of JWTs and nonces to make API calls that I shouldn't, its not a v8 vuln |
| 20:45:30
| <bradleymeck> | its a JS language problem |
| 20:48:12
| <caitp> | so, you could do the same thing in node-chakra or whatever it's called, presumably |
| 20:48:31
| <caitp> | still sounds like something the committee might care about stomping out if it's dangerous in any way |
| 20:50:01
| <bradleymeck> | yes |
| 20:50:15
| <bradleymeck> | its part of the reasoning for frozen realms proposal and the bind syntax proposal |
| 20:50:22
| <bradleymeck> | but those have stalled |
| 20:53:49
| <caitp> | hm |
| 21:23:19
| <bradleymeck> | caitp: did that clarify things? |
| 21:25:34
| <caitp> | sure |
