08:17:16 [Jungkee]
Present+ Jungkee_Song
08:17:19 [Lachy]
sicking: no.
08:17:25 [bryan]
the use cases I am thinking of are similar, e.g. generically the ability to download content as a package and store locally for use in the app
08:17:35 [Lachy]
… I don't think it's just performance. Convenient for deployment to have a single file.

Wonsuk has joined #webapps

08:19:14 [Lachy]
maciej: For the use cases, it seems useful to download a zip and then reference its resources by URL.
08:19:27 [Lachy]
sicking. It would be useful to have a zip protocol handler.
08:19:46 [Lachy]
… It could possibly work with a URL, like jar handler.
08:19:54 [Lachy]
maciej: Is there a list of these use cases?
08:19:59 [Lachy]

08:21:49 [Lachy]
maciej: I want to the use cases on the table.
08:22:12 [Lachy]
chaals: We will. That comes with the proposal. Discussion about it will take place over several weeks.
08:22:52 [Lachy]
… Testing. We had this as an agenda topic.
08:23:13 [Lachy]
… We could spend a lot of time looking in details, or we could spend the extra time actually making tests.

Topic: Testing
08:23:39 [Lachy]
Chaals: We need a test facilitator.
08:24:14 [Lachy]

08:24:33 [Lachy]

chaals: I have a proposal for something that falls into the App Cache area. Not sure if this is the right group. Called Prefetch.
08:31:15 [Lachy]
… It allows a site that uses a lot of resources again and again, give a manifest of files to prefetch.
08:31:24 [Lachy]
… Not sure if I'm going to propose it as a work item.

08:36:05 [Lachy]
… The first one is on search websites, there are suggestions for what the user is currently typing.
08:36:17 [Lachy]
… Bad overlap from the IME suggestions and the search suggestions.
08:36:30 [Lachy]
… A lot of complaints from Chinese and Japanese users.
08:36:56 [Lachy]

rotsuya has joined #webapps
08:38:22 [Lachy]
… Two use cases. 1. On Windows, if you play a FPS game, and you press one of the IME keys, it creates problems. Need to avoid IME menu interferring with game.
08:38:53 [Lachy]
… 2. Entering a name in a game, native UI for IME suggestion doesn't fit with game design UI.
08:39:20 [evanli]

08:47:00 [chaals]
[Sorry Dmitry, but it was when you started getting impassioned that it started turning into a sales pitch… I thought you had explained your technical perspective well enough to let people think about the ideas...]
08:47:06 [Lachy]
… It's in one of the draft specs. Have you considered that and is it similar?
08:47:28 [Lachy]
KenjiBX, There is a function for that to hit at that. Similar to CSS, but in JS.
08:47:44 [Lachy]
adrianba, maybe we could consider if we need both.

08:48:30 [Lachy]

topic: Selectors API Level 2
09:17:39 [mjs]
ScribeNick: mjs
09:17:58 [mjs]
LH: I'll start by giving an overview
09:18:15 [mjs]
LH: functionality of the find and matches methods is pretty stable
09:18:19 [mjs]
LH: test suite has many tests
09:18:26 [mjs]
LH: hopefully we can get implementations soon
09:18:40 [mjs]
LH: I'm hoping we can settle the naming issue for the methods find and findAll
09:18:59 [mjs]
LH: Issue for parsing comments in selectors still needs to be addressed - hopefully CSS WG can address it in Selectors 4
09:19:14 [mjs]
LH: there was a brief discussion with Anne about merging Selectors API v2 with DOM4
09:19:24 [mjs]
LH: and possibly introducing extra functionality
09:19:35 [mjs]
LH: I wanted to discuss the return type for the findAll method
09:19:48 [mjs]
LH: NodeList, Array, or some new object that provides a combination of functionality
09:19:50 [massimo]
massimo has joined #webapps
09:19:54 [mjs]
LH: Use cases:
09:20:03 [mjs]
LH: (1) get a collection of elements as a result of the query
09:20:07 [glenn]
glenn has joined #webapps
09:20:13 [mjs]
LH: (2) run methods that apply collectively to all the elements
09:20:24 [mjs]
LH: right now you have to iterate individually
09:20:30 [chaals]
q+ to try and squash the naming issue
09:20:34 [mjs]
LH: (3) filter the list or run additional queries on the list
09:21:25 [mjs]

09:22:08 [mjs]
LH: (a) normal JavaScript array - would give normal Array functionality but could not add selectors-specific methods
09:22:19 [mjs]
LH: (b) return a NodeList; but no Array-like functionality
09:22:54 [mjs]
LH: (c ) define a custom object which imports functionality from Array and NodeList, but adding Selectors-specific stuff
09:23:37 [mjs]
AR: I'm from ECMA TC39; hard to add Array functionality due to NodeList because of closures
09:23:39 [odinho_]
s/selectors-specific methods/selectors-specific methods (e.g. having a new .findAll() make a union)/
09:23:51 [mjs]
AR: I'd prefer to define an Array subtype or to recast NodeList as an Array
09:24:10 [glenn]
glenn has joined #webapps
09:24:19 [mjs]
AR: there's a preference to make these things Arrays from the pov of developers and JavaScript
09:24:27 [mjs]
CMN: I'd like to address names
09:24:41 [mjs]
CMN: everyone likes find(), findAll(), right?
09:24:45 [mjs]
(no objections heard)
09:24:54 [mjs]
CMN: that's straw consensus and it's a non-technical issue
09:24:58 [mjs]
LH: that about covers it
09:25:17 [mjs]
CMN: as an implementation question, what about compatibility?
09:25:40 [rubylin]
rubylin has joined #webapps
09:25:42 [mjs]
LH: the problem with converting NodeList to an Array is that NodeLists are generally live in many uses so you can't import mutable methods from Array
09:25:50 [mjs]
AR: I actually don't think that's a big problem
09:26:14 [mjs]
AR: first, the liveness is a feature of someone else holding an API
09:26:31 [mjs]
AR: this is not something that is foreign
09:26:42 [mjs]
AR: but for the question of adding new invariants, we can model that with proxies
09:27:11 [mjs]
CMN: any other comments, questions?
09:27:21 [mjs]
LH: matches() is implemented with a prefix in all browsers
09:27:29 [mjs]
LH: no one implements scope or reference nodes yet
09:27:43 [mjs]
CMN: any other implementor notes?
09:27:55 [Yoshihiro]

TL: just an observation that the extra functionality for chaining seems like a much more generic feature - maybe should not be specific to Selectors API, maybe should be in DOM 4
09:28:19 [mjs]
CMN: back to agenda
09:28:37 [mjs]
CMN: working backwards, at 16:45 we have Web Intents - can't change that time, dial-in
09:28:48 [mjs]
CMN: session on testing, James has agreed to lead
09:28:59 [mjs]
CMN: the goal is to sit in the room and write tests - hands-on session
09:29:18 [mjs]
CMN: will end at 16:45 and will begin when we finish everything else
09:29:26 [mjs]
CMN: after lunch, short session on the Web Platform effort

10:44:57 [timeless]
... as a vendor, yandex has stuff which does apps based on a JSON package
10:45:12 [timeless]
... as our app is built from Chromium, it uses the same JSON as Chrome
10:45:16 [timeless]

10:48:00 [timeless]

13:05:42 [Lachy]

… [Now showing an example testing function that tests this assertion]
13:13:01 [Lachy]
… 2. Async tests.
13:13:28 [Lachy]
… Some tests depend on waiting for events, network responses or other non-synchronous features.
13:14:16 [Lachy]
… Test authors should write using the normal event handlers for the feature being tested and include test functions within those event handlers.

… [Example on screen showing an asynchronous test function called by setTimeout]
13:15:20 [Arno]

13:15:43 [Lachy]
… t.step() takes a function, which runs the tests.

… That's a high level overview. Any questions?
13:43:18 [Lachy]
SimonPieters: For the W3C tests, jgraham said we have 3 formats. Can we replace manual tests with WebDriver tests?
13:43:39 [Lachy]

… The actual specification is lagging behind.
13:50:06 [Lachy]

mounir - glad to hear it. carry-on then. thanks.
15:52:02 [Lachy]
… The nice thing is that the first web app that launches the intent doesn't have to know about the next one.
15:52:17 [Lachy]
… That's the loosely couple benefit that comes from this system.
15:52:36 [Lachy]

15:57:54 [Lachy]
… The use of this picker is a lot higher than we would like.
15:58:04 [Lachy]
… It ends up being a lot of steps.
15:58:46 [Lachy]
… User has to check permissions when setting up a new app. Incorporating app discovery and installation into the picker doesn't work, from a user interaction perspective.
15:58:58 [darobin]

15:59:27 [Lachy]

16:14:56 [Lachy]

16:15:25 [Lachy]

16:16:12 [MikeSmith]
q?
16:16:46 [Lachy]
npdoty: I mostly work on privacy in standards. To follow up, as I understand, the intents spec as it is now, the intents are done as service by a user clicking a button.
16:17:17 [Lachy]
… But a user could also potentially share any URL from teh browser UI, even if the page doesn't explicitly support the intent.
16:17:42 [Arno]
q+ to ask status on intents semantics
16:17:54 [Lachy]
Greg: The spec deals with it in a tangental way. It says that the intent may not be invoke by the API given and allows for the browser to get in the middle on one end or the other of the system.
16:18:21 [Lachy]
… The spec can't force the browser to do it, so it's allowed but not mandated in the spec.
16:19:25 [Lachy]
… I think we have a good sense of the interchange format to say how to transfer images or URLs as a data packet.
16:20:09 [Lachy]
sicking: We in Firefox had the need for something similar to this, but since web intents wasn't done, we did something else.
16:20:36 [Lachy]
… We have web activities which is similar. It has the same capabilities. Very much tied into apps. The user brings up an app, rather than a new tab.
16:21:32 [Lachy]
… one of the UI problems we had is that if you have multiple handlers for a given intent, you need to show some sort of UI so the user can choose.
16:21:40 [Lachy]
… what text string to you put in the title of that UI.
16:22:21 [Lachy]
… We put application names next to each option. I don't know if you can do that in your implementation, given that there is no trusted name for a website.
16:23:15 [Lachy]
Greg: In Chrome, the picker has a string that is related to the action that was performed by the user. There's a custom string per action and a generic one if we don't know what the action is. Something like "which service should we use?"
16:23:21 [Lachy]
Sicking: how do you describe the options?
16:23:47 [Lachy]
Greg: We think that using the name of the app is the most clear. The service can provide a custom string for this.
16:24:29 [Lachy]
… I think the reason that that ends up being useful than just the name of the application is that when you see the UI, you're picking an application.
16:25:01 [Lachy]
sicking: one problem is trust. It's possible to phish this.
16:25:20 [Lachy]
… I could change my icon and title to Bank of America, and fool the user.
16:25:42 [Lachy]
… It's part of the Chrome UI, so it feels more trustwothy, but in reality, it's part of the web content.
16:25:55 [Lachy]
Greg: That's a problem with the picker that we had.
16:26:33 [Lachy]
… That's one slice of the problem with using the picker that we discoverd. I agree there would be a phishing risk.

… It's bug we need to fix.
16:27:47 [npdoty]
