08:47 | <Domenic> | No action needed for some time, but here are some musings on how to specify Summary: every throw completion should store the active ScriptOrModule + relevant ParseNode. (Either directly in the JS spec, or via a host hook.) And we'd need some way of translating ParseNode into lineno + colno, which I don't think there's any spec machinery for right now. |
08:48 | <littledan> |
|
08:50 | <Domenic> | If that'd be useful by whatever's consuming the end result, for sure. Do you have thoughts on exposing that on ErrorEvent ? |
08:52 | <littledan> | Right, either that or just automatically running the event within that snapshot (initially leaning towards the latter, now considering the former) |
08:53 | <littledan> | https://github.com/tc39/proposal-async-context/issues/90 |
08:53 | <littledan> | and the same for unhandled rejections |
08:53 | <Domenic> | Nice, that might be motivation for doing some of this work sooner rather than later, then. |
08:54 | <Domenic> | Or at least provide a path to follow if we ever do get around to cleaning up the ErrorEvent spec to the degree I'm talking about. |
08:55 | <littledan> | is there some cross-browser difference in when these properties are assigned? (allocation vs throw time) |
08:56 | <littledan> | also re muting: now that we're standardizing ignoreList in TC39-TG4 (source maps), we might want to say something about how that relates to other parts of black boxing |
08:56 | <littledan> | for example we might want ignoreList2 which does full black boxing (apparently Mozilla initially implemented it this way, probably because we didn't have specs for anything) |
08:57 | <Domenic> | There are definitely differences in muting. There are also reportedly differences in pre- vs. post-redirect URLs for filename . Not sure about allocation vs. throw time but I kind of remember that also being different, hmm. |
08:57 | <littledan> | sounds like fun, I'm glad you're working on that! |
08:58 | <Domenic> | Ehhhh am I though... |
08:59 | <littledan> | if you're not, then maybe we can recruit others here to try to help |
08:59 | <littledan> | (e.g., from the source map or AsyncContext groups) |
09:01 | <Domenic> | A coworker (Jeremy) is doing some spec cleanup work as part of a rotation, and I got sniped into spending Friday evening musing about this stuff, so I dropped some ideas into the thread for the future :). Any help would definitely be appreciated. |
