I see that the locus of EME debate seems to have now shifted away from W3C forums and on to blink-dev
00:43
<MikeSmith>
that's progress
00:47
<MikeSmith>
in other news, now that the HTML spec requires the title element to have non-whitespace content, we'll need to choose some stock value for the title attribute to use in the minimal boilerplate HTML document in the text-field input feature of the validator
00:47
<MikeSmith>
anybody have suggestions?
00:49
<jamesr__>
anyone here familiar with the charset attribute on Document?
00:49
<jamesr__>
it's in blink with a comment "// IE extensions" as an attribute DOMString
00:49
<jamesr__>
notable, not readonly
00:50
<jamesr__>
we appear to "support" (for some definition of that word) writing a value to the attribute
00:50
<jamesr__>
i don't know what it actually does
00:51
<jamesr__>
i can't find references on MDN, but maybe i just suck at it
00:52
<jamesr__>
mozilla doesn't appear to have it (according to http://mxr.mozilla.org/mozilla-central/source/dom/interfaces/core/nsIDOMDocument.idl)
00:59
<jamesr__>
in blink they date back from when the property was defined in a file called khtml/ecma/kjs_dom.cpp
01:08
<esprehn>
Hixie_: it's not clear, it puts it in the DOM Manipulation Task Source, but the onload is just handled by the "delays the load event" logic
01:08
<esprehn>
Hixie_: Do things in the DOM Manipulation Task Source delays the load event ?
01:12
<esprehn>
I see, they are the same task source
01:12
<esprehn>
it'd be nice if the spec made this more clear, there's just a sentence in each section that mentions the task source
01:14
<esprehn>
Hixie_: it's unfortunate that autofocus is speced like this, it means there has to be a recalculate style before the onload event can fire, since we need to know the style to decide if something is focusable.
01:18
<esprehn>
I suppose developers should listen for DOMContentLoaded instead since onload is doomed to slowness
03:36
<MikeSmith>
damn can you devs at google please quit using the term "drive-by web" already
03:36
<MikeSmith>
I don't see any signs that anybody else is buying into that term
04:29
<matjas>
MikeSmith: how about <title>Test</title>?
04:30
<MikeSmith>
matjas: sounds good
04:30
<MikeSmith>
I will make it so
04:39
<MikeSmith>
matjas: pushed https://bitbucket.org/validator/validator/commits/4f4c6243d2da0b596304c830d9c642802c4d15cb
04:39
<MikeSmith>
thanks
04:40
<matjas>
MikeSmith: yay! good point about the other bugzilla tracker btw, i had forgotten about it
04:42
<MikeSmith>
matjas: yeah, until hsivonen has time to deal with load issues for the bugzilla.validator.nu server, that's probably the best place
04:43
<MikeSmith>
matjas: btw, about table@sortable, nobody implements that yet right?
04:43
<MikeSmith>
are there any polyfills for it yet?
04:44
<MikeSmith>
and about <data> it's implemented in the validator sources but not yet pushed to http://html5.validator.nu/ or http://validator.nu/ yet
04:53
<matjas>
MikeSmith: i don't think so, no. But note that it also errors on <data> in that context
04:56
<MikeSmith>
matjas: the <data> part should work at least at http://validator.w3.org/nu/ (which is running the current sources from the repo)
05:00
<Hixie_>
MikeSmith: <title>Page Title Here &mdash; Site Title Here</title> maybe?
05:00
<Hixie_>
esprehn: hm, it wasn't my intent to make that bad, but let me look...
05:01
<MikeSmith>
Hixie_: that'd work too I guess
05:02
<Hixie_>
esprehn: hm, i guess if you're so quick to finish loading the doc that you can fire 'load' almost immediately, you could end up with it sitting behind the many tasks that want to resolve style to figure out what can be focused
05:02
<Hixie_>
esprehn: note that DOMContentLoaded is on the same task source, so it would also be delayed
05:03
<Hixie_>
esprehn: also, technically, you are already required to resolve style before firing 'load' since you (per spec, anyway) are supposed to render between each task
05:03
<Hixie_>
esprehn: so you'd resolve style and layout and render between the parser task that stopped parsing, and the DOMContentLoaded/load tasks
05:05
<esprehn>
Hixie_: that's definitely not how browsers work, we're not going to resolve style or layout between tasks
05:06
<Hixie_>
esprehn: yeah, well, so long as it _looks_ like you do :-)
05:07
<Hixie_>
esprehn: for the autofocus thing, i can use another task source
05:07
<Hixie_>
not sure which exactly
05:07
<Hixie_>
user interaction task source maybe
05:07
<esprehn>
Hixie_: The sad thing is if you had <input autofocus> and then onload = function() { doSomethingThatInvalidatesStyle(); } the current spec means we calculate the style twice
05:08
<Hixie_>
oh i'm convinced of the badness here, don't worry
05:08
<esprehn>
:)
05:09
<Hixie_>
interesting, there is _some_ precedence for using the user interaction task source for non-user interaction tasks
05:09
<Hixie_>
calling input.select() does it
05:09
<Hixie_>
i guess that makes sense
05:09
<esprehn>
webkit and (old) opera both do autofocus inside "layout"
05:10
<esprehn>
ex. appendChild(input with autofocus); input.offsetTop; // focus happened inside this
05:10
<Hixie_>
woah
05:10
<Hixie_>
that's... special
05:10
<esprehn>
Firefox appears buggy, it frequently seems to not do autofocus at all
05:11
<Hixie_>
well, you're allowed to not focus
05:11
<Hixie_>
so you can get a synchronous 'focus' event during the call to offsetTop?
05:11
<esprehn>
yes
05:11
<Hixie_>
that's definitely pretty special
05:11
<esprehn>
webkit/blink and old opera all do it
05:12
<esprehn>
autofocus is handled at the time when the render tree is constructed
05:12
<Hixie_>
what happens if the dom is manipulated as this happens?
05:12
<esprehn>
same thing as mutation events
05:12
<Hixie_>
_mutation events_ happen during layout?!
05:13
<esprehn>
oh no :)
05:15
<Hixie_>
http://software.hixie.ch/utilities/js/live-dom-viewer/saved/2470
05:15
<Hixie_>
i don't understand why chrome can't find the node
05:15
<Hixie_>
does it calculate layout before running inline <script>?
05:15
<Hixie_>
does querySelector() calculate layout?
05:16
<Hixie_>
(change autofocus to autofocusx and it works)
05:16
<esprehn>
offsetTop calculates style (1) and then does layout (2), in between those two steps we fire the focus event handler
05:16
<Hixie_>
so if the focus handler moves the node in the DOM, the layout is what? using the old cascade?
05:16
<Hixie_>
but the new location?
05:17
<esprehn>
using the new location
05:17
<Hixie_>
but what style?
05:17
<esprehn>
focus causes another recalc style, so you end up with recalc style (1) -> focus event -> recalc style (2) -> layout -> return offset value
05:18
<Hixie_>
oh you check if the event changed things, and start over if it did?
05:18
<esprehn>
yup
05:18
<Hixie_>
what if the focus event added a new element with an autofocus attribute?
05:18
<esprehn>
that's why I was talking about mutation events
05:19
<esprehn>
I think we'll do it all over again, if you continued adding autofocus things we'll hang
05:19
<Hixie_>
i can't get chrome to operate as you describe. it seems to evaluate style earlier than when i call offsetTop.
05:20
<esprehn>
yeah, right now we do it inside the parser...
05:20
<esprehn>
I'm working on fixing that
05:20
<esprehn>
autofocus happens the second the parser inserts the child right now, there's no "posting a task"
05:20
<Hixie_>
wow, autofocus right now does a synchronous during-parse style recalc and layout? :-)
05:20
<esprehn>
no layout :)
05:21
<Hixie_>
well, still
05:21
<Hixie_>
wow
05:21
<Hixie_>
ok
05:21
<Hixie_>
well anyway
05:21
<esprehn>
blink and webkit right now calculate the style of every element as the parser inserts them
05:21
<Hixie_>
i suggest just doing it on a task
05:21
<Hixie_>
a task that's on the same task source as click events, etc
05:21
<Hixie_>
since you can't process those without a layout either
05:23
<esprehn>
yeah, I'll look into if we can do that
05:23
<Hixie_>
k, i'll update the spec accordingly. keep me posted.
05:27
<esprehn>

idna-update keeps blocking my emails...
12:20
<annevk>
oh well, they'll get to www-tag
12:22
<SimonSapin>
annevk: did they black-list you? ;)
12:23
<annevk>
too many email addresses or some such
12:23
<annevk>
I think someone actually white-listed me because I couldn't post to the list at all before and wasn't interested in subscribing
12:24
<annevk>
SimonSapin: what does Servo do for IDNA?
12:25
<SimonSapin>
haha
12:25
<SimonSapin>
is this a real question?
12:27
<jgraham>
Sero priorities: a) Implement getElementById, b) Implement a whole web browser c) Implement IDNA
12:27
<jgraham>
*Servo
12:27
<annevk>
SimonSapin: well, since it has URL processing...
12:28
<SimonSapin>
I would be surprised if it’s supported at all
12:28
<SimonSapin>
right now HTTP is disabled because of recent changes in Rust’s IO
13:05
<gsnedders>
Servo: the web browser without HTTP support.
13:06
<SimonSapin>
who needs HTTP anyway
13:06
<gsnedders>
I hear SPDY is the future.
13:07
<Ms2ger>
HTTPbis
13:07
<jgraham>
Have to start with HTTP/0.9 only
13:09
<gsnedders>
jgraham: But then you also need to start off with content-type sniffing.
13:10
<jgraham>
gsnedders: Of course! But everyone knows that you implement specs one at a time in order and get full conformance to older specs before starting on newer ones.
13:10
<jgraham>
I particularly look forward to the HTML+ support
13:12
<gsnedders>
Personally I'm just waiting for HTML 3.0, so I can then file bugs to remove it. Because that's my hobby.
13:21
<GPHemsley>
annevk: Here now
14:52
<annevk>
GPHemsley: so the situation is this...
14:52
<annevk>
GPHemsley: we're gonna have to do some sniffing at the Fetch level
14:52
<annevk>
GPHemsley: to determine if the response is a ZIP thingie
14:52
<annevk>
GPHemsley: https://gist.github.com/annevk/6295844 has a high-level sketch of this feature
14:53
<annevk>
Hmm, HTTP... gotta spec that too someday
15:04
<GPHemsley>
annevk: Alright; one of the problems I ran into with ZIP was that a lot of various office suite file formats use it as a basis.
15:04
<GPHemsley>
annevk: What do you need me to do?
15:04
<GPHemsley>
Ms2ger: Did you ever implement the attribute sorting in anolis?
15:05
<annevk>
GPHemsley: I'd like you to think about how that makes sense architecturally or if we just need to accept sniffing at various layers...
15:08
<GPHemsley>
annevk: Is the old zip: proposal still in the running, or are you committed to media fragments?
15:12
<GPHemsley>
annevk: Also, doesn't fragment evaluation occur after the resource is loaded?
15:12
<Ms2ger>
GPHemsley, no, don't think so
15:12
<annevk>
I'm pretty sure nested URL schemes is not going to be a thing.
15:13
<GPHemsley>
annevk: Thus, load resource -> sniff type -> evaluate fragment -> navigate to fragment location
15:13
<annevk>
GPHemsley: at which point you might "load" a subresource and sniff type again
15:14
<GPHemsley>
annevk: Sgtm; is that a problem?
15:14
<annevk>
Normally fetch returns a resource which is sniffed. Now fetch retrieves a resource, sniffs it, and returns a subresource.
15:15
<GPHemsley>
That's the reality of the situation. I'm not sure you can get around it.
15:15
<annevk>
This changes where sniffing happens. It also changes where certain fragments are handled.
15:15
<GPHemsley>
You are indeed loading two different resources.
15:15
<annevk>
Yeah, that was my conclusion too. Was wondering whether there was another way.
15:16
<GPHemsley>
There may be, but I'm not seeing any problem with the obvious way.
15:17
<GPHemsley>
Other than the one raised by sicking about the nested fragments
15:17
<GPHemsley>
but that's not necessarily part of the network stack
15:17
<GPHemsley>
more a URL syntax issue
15:18
<GPHemsley>
what if you had #path=#anchor ?
15:19
<GPHemsley>
as in <a href="#path=subdir/file.html#subheader">
15:20
<GPHemsley>
or perhaps use a different symbol or percent-encoding for the embedded fragment ID
15:20
<GPHemsley>
-ID
15:20
<GPHemsley>
hmm
15:20
<GPHemsley>
that part needs more thought
15:20
<GPHemsley>
but I think the sniffing issue is fine
15:20
<annevk>
#path=x&id=test exists. However, it's not entirely clear to me we want to support it in browsing contexts just yet. There's more complication there.
15:21
<GPHemsley>
one step at a time, I suppose
15:21
<annevk>
Just resource loads should be sufficient for the use cases that have come up thus far.
15:21
<GPHemsley>
but is there a reason you can't do file.zip/subdir/file.html ?
15:21
<GPHemsley>
or will that not work on the server side?
15:22
<annevk>
GPHemsley: The request to the server will be for /file.zip/subdir/file.html ...
15:22
<GPHemsley>
right
15:22
<GPHemsley>
hmm
15:23
<GPHemsley>
oh well
15:25
<GPHemsley>
but yeah, load resource -> sniff type -> evaluate fragment -> load subresource from path -> sniff type -> display
15:25
<GPHemsley>
it's probably OK to treat resources inside ZIPs as sandboxed in such a way that there is decreased functionality
15:25
<SimonSapin>
GPHemsley: is this recursive? :]
15:25
<SimonSapin>
a zip in zip
15:26
<GPHemsley>
SimonSapin: That's a good question
15:26
<SimonSapin>
http://en.wikipedia.org/wiki/Zip_bomb
15:26
<GPHemsley>
and it probably falls into the same boat as the regular (HTML) page fragments
15:27
<annevk>
SimonSapin: I don't think we'll support recursion
15:28
<GPHemsley>
What about file.zip?path=
15:28
<SimonSapin>
annevk: yeah, it sounds not very useful and potentially dangerous
15:30
<GPHemsley>
Another way is to treat the zip file as if it's an embedded domain
15:30
<GPHemsley>
as in, relative links inside the ZIP can't get out of the ZIP
15:31
<GPHemsley>
such that <a href="#anchor"> gets turned into file.zip?path=subdir/file.html&id=anchor
15:31
<GPHemsley>
or something
15:31
GPHemsley
shrugs
15:32
<GPHemsley>
oh, s/?/#/
15:32
<GPHemsley>
force of habit
15:32
<GPHemsley>
but then if you have an embedded fragment for image dimensions, you'd need to deal with that
15:33
<GPHemsley>
so <a href="#xywh=160,120,320,240"> inside /package.zip#path=image.jpg would get navigated to /package.zip#path=image.jpg&xywh=160,120,320,240
15:34
<GPHemsley>
given that media fragments seems to allow multiple name-value pairs with the same name, you might be able to get away with #path=image.zip&path=embedded.html
15:35
<GPHemsley>
but this is me trying to solve problems you didn't really ask me about :)
15:37
<GPHemsley>
annevk: Would this proposal be a generic one that could possibly be extended to all archive types?
15:58
<annevk>
GPHemsley: it's not clear to me we want to support all archive types
16:42
<Domenic_>
is someone working on making svg support css gradients? (is that already specced?) because dropping back to markup to declare these gradients is just feeling silly.
16:43
<annevk>
Domenic_: TabAtkins would know, can also check public-fx for that I think
16:43
<annevk>
Domenic_: it's the CSS/SVG coordination group; given that such coordination is happening, I suspect they're on it
16:45

<Domenic_>
weinig: Ms2ger: annevk: public.
17:19
<annevk>
weinig: and the unwrapping might move entirely to the then() method; but by and large...
17:19
<weinig>
fair enough
17:19
<annevk>
thanks Domenic_
17:30
<TabAtkins>
Domenic_: Yes, the idea is that fill/stroke will support the CSS <image> type as well.
17:30
<TabAtkins>
(And vice versa.)
17:31
<TabAtkins>
That is, SVG paint servers will work as <image> type in CSS.
17:31
<Domenic_>
TabAtkins: thank goodness. How's progress on that front? Distant-future, or living-spec-as-soon-as-someone-implements-it?
17:32
<TabAtkins>
The SVG-in-CSS part is roughly living spec, in Images 4 (check out element()). The CSS-in-SVG part is expected, but hasn't been written yet.
17:33
<Domenic_>
awww
17:33
<Domenic_>
(but yes, element() is great stuff.)

<zcorpan>
anyone want to finish reviewing https://critic.hoppipolla.co.uk/r/32 ?
18:23
<jamesr__>
annevk: i would tend to agree. i'm adding instrumentation to Blink for document.charset and document.defaultCharset to confirm
18:23
<jamesr__>
annevk: if it turns out those things do appear to be needed, i'll let whatwg know. if it turns out they aren't (which is hopefully the case) i'll let WebKit know they can probably remove them too
19:18
<zcorpan>
something that would be fun to do: subscribe to annevk's blog but with the posts from 10 years ago
19:19
<zcorpan>

oh woah i never noticed that "SVG sucks" changed to "URLs suck", haha
19:55
<TabAtkins>
Whatever he's currently play with sucks.
20:04
<Domenic_>
i feel like it was SVG for years.
20:07
<zcorpan>
it was svg since jan 2009
20:07
<zcorpan>
dunno when it changed to urls
20:08
<zcorpan>
or what it was before svg
20:08
<nimbu>
annevk: ^^
20:08
<nimbu>
inquiring minds want to know
20:10
<jarek>
I haven't seen anybody notable to say that SVG sucks
20:10
<jarek>
maybe except Alex Russel
20:10
zcorpan
just knows the svg date because he made the svg version and still has it at http://simon.html5.org/dump/
20:10
<jarek>
CSS3 definitely sucks more with the prefix hell
20:12
<Hixie_>
saying svg "sucks" is an oversimplification
20:12
<Hixie_>
but it certainly has some serious issues
20:13
<Hixie_>
(the wg has done some work to mitigate those over time)
20:58
<aklein>
Hixie_: hi there. http://www.whatwg.org/specs/web-apps/current-work/multipage/urls.html#dynamic-changes-to-base-urls seems to suggest that moving an <img> between document's shouldn't cause it to re-fetch any resources (and to simply keep displaying whatever it was displaying before), but quick tests suggests this isn't the case in either Blink or Gecko
20:58
<aklein>
(both re-resolve). Am I misreading the spec, or is there a bug somewhere?
21:00
<aklein>
(trying to figure out how URL resolution plays with <link rel=import>
21:42
<Hixie_>
aklein: probably a bug in the spec, the cross-document stuff isn't well documented
