/cc @nodejs/diagnostics @nodejs/post-mortem

[joshgav]

Will fill in the agenda with relevant issues from this and other repos. Please suggest more in this thread.

Everyone please fill in the Doodle by end of week (1/13) so we can settle on a time.

@mhdawson @yunong @rnchamberlain @richardlau - would it be worth discussing topics from the nodejs/post-mortem repo in the Diagnostics meetings too? For me at least I try to stay deeply on top of both :)

[mhdawson]

I won't be able to make it the week of Jan 16-20 as I'm off on holiday.

[rnchamberlain]

@joshgav yes it would be good to discuss some of the post mortem work if there is time in your meeting, doodle poll updated, thanks

[joshgav]

@mhdawson are you asking us to defer for a week? Otherwise, I think Thursday at 2000 UTC (12pm Pacific) works for everyone, so I updated the OP accordingly.

I also added a number of issues to the agenda from here and nodejs/node, we can trim if some can simply continue progressing through discussion in GitHub. If you'd like to add others please comment here or edit the OP if you prefer.

Thanks!

[watson]

I'm going to NodeConf Budapest on the 19th unfortunately, so I don't think I can make it 😞
I updated the description to say you should 👎 if you can't make it so @joshgav knows if people have seen it

[joshgav]

Reminder that we're scheduled to meet tomorrow (Thursday 1/19) at 12pm US Pacific, 2000 UTC. See you then!

AsyncHooks is such a minor part of todays agenda that I'm not going to join.

A short update on async_hooks (it is actually all I know)

A while ago Trevor said the following where missing:

• Remove all weak objects (will be handled in another PR to solve another issue)
• Add support to node::MakeCallback
• Implement public native API.
• Detect a change in the hooks queue when in the middle of running hooks, so the original set of hooks can finish executing.

My best guess is that only "Add support to node::MakeCallback" and "Implement public native API" is missing now, but that he want to test the current implement first.

[richardlau]

Apologies, this is my first time using Hangouts. I'm getting a 403 error trying to access the participate link in the description.

[rnchamberlain]

[joshgav]

Thanks, working on it now. Perhaps you need to be signed in to a Google account? We're testing here in the MS office too.

[joshgav]

Confirmed that you need to be signed into a Google account. Can you try that?

[rnchamberlain]
