CFAM (that's "Call for agenda modification". I'm making it a thing – Jake)

• Anything folks want to cover that isn't part of the agenda?
• Any items that should be done at a certain time, or depend on particular people?

  • [ ] What next? Would a polyfill or spec help?

Dinner

Unfortunately, dinner registration is closed. If you registered (see below list), here are the details:

• Location: Yohira (https://goo.gl/maps/aNyJhFui45FJVKBj6)
• Time: 7pm
• Registered people: acomminos, asa.kusuma, asuth, bashi, beverloo, dharani, dom, domenic, dpc, falken, hayato, jakearchibald, jungkee.song, mek, n8s, nhiroki, rayankanso, shimazu, (slightlyoff), stevebe, tsteiner, wanderview, yhirano, youenn, yutakasai

It's a 30-45 min walk (3 km) from the hotel or 10 minute taxi. Meet at 6:30 at the hotel front lobby (4F) if you want to taxi over.

[wanderview]

I'm working on a proposal giving sites more control over how scopes match that I'd like to discuss. I'm hoping to post as an issue later this week or early next week.

[asakusuma]

Thanks for putting this together @mattto. Regarding the SW Lifetime item, another possible sub-item would be the "abortable algorithms" proposal https://github.com/w3c/ServiceWorker/pull/1443 (cc @jakearchibald). That proposal may be part of the puzzle to landing an algorithm for killing a service worker https://github.com/w3c/ServiceWorker/pull/1440, which would also be a good sub-item for the SW Lifetime discussion.

[mfalken]

Thanks, @wanderview and @asakusuma. Incorporated into the issue.

[mfalken]

Would people be interested in a group dinner after the meeting? If you're interested in joining, can you thumbs up this? EDIT: please fill out this form: https://forms.gle/wcGRxDtsBwQokRRS9

FYI, I've filed #1468 with my service worker scope proposal.

I made a dinner reservation at a nearby place for after the meeting. It will be a course meal of recommended seasonal food (kaiseki). If you want to attend, please fill out this form by Thursday, Sept 12 at 5pm (in your timezone): https://forms.gle/wcGRxDtsBwQokRRS9

I'll have to confirm the number of people by then. Thanks!

[yutakahirano]

Can we talk about fetch streaming upload (https://github.com/whatwg/fetch/pull/425)?

[mfalken]

@yutakahirano: Added it to the agenda.

[jakearchibald]

Note we're now starting at 9am rather than 8:30am, because we're not monsters.
