glazou: Let's start
glazou: Any extra items?
astearns: I'd like to publish another WD of Regions.
glazou: We can do that as the first item.
glazou: Any others?
Publish New WD of Regions
-------------------------
<astearns> http://dev.w3.org/csswg/css-regions/#changes_from_Feb_18_2014
astearns: The only thing changed is the introduction. Here's the
change list (above).
astearns: It's been over 6 months since last publication so I'd
like to publish again under the new process.
Rossen: I thought we were doing that at the last F2F for multiple
drafts including Regions.
astearns: I hadn't seen that in minutes so I assumed we were out
of time after I left.
Rossen: In the meantime, we can ask for objections in case we
didn't resolve at the F2F.
* Rossen didn't see Regions on the minutes either...
<Bert> (Intro looks good, so I'm OK with publishing.)
<dauwhe> very nice intro!
<astearns> dauwhe Bert thanks
glazou: Any objections?
RESOLVED: Publish new WD for Regions
TPAC
----
glazou: It's not far away and we haven't started collecting items.
glazou: I don't think we have a wiki page even and so we need that
and to collect agenda items. Anything else about TPAC?
dauwhe: dpub does want a joint meeting with CSS. It's tricky with
them being on the Thursday and Friday. Is that a
conversation for the administrative list?
glazou: Yes, probably.
fantasai: Question is do we want to meet with them on Monday or
Tuesday or do we send a delegation to one of their
meetings?
dauwhe: I proposed they'd meet us on Monday, but they want
Thursday or Friday.
glazou: So what amount of time do they need and to discuss what?
dauwhe: Box tree API and pagination issue, I think. Probably an
hour at least.
glazou: Okay.
florian: Is Wednesday dedicated to certain topics or can we use it
for this?
TabAtkins: Wednesday isn't a meeting day.
florian: Perhaps as a part of the un-conference.
dauwhe: I think for this topic there are people we'd need but not
everyone. I also don't know everyone's plans.
fantasai: Why don't you make a list of the people you need and we
can look at schedules?
glazou: Also about TPAC, we got a message that 2015 TPAC will be
on the last week of October and the location is Sapporo in
Japan.
<Bert> Don't forget to register! Price goes up on Oct 8. (Most of
us have, but maybe a handful hasn't:
https://www.w3.org/2002/09/wbs/35125/TPAC2014/ )
<dbaron> I created a stub page for
https://wiki.csswg.org/planning/tpac-2014
Overwriting an important style
------------------------------
Rossen: We collected a bunch of data and tried to look through the
results.
Rossen: What we see currently...Out of almost 600 million hits we
found with all kinds of important rules, very few of them
would match the pattern, like something in the 100 range
which suggests a tiny ratio.
Rossen: Of the content we could scan...
Rossen: I think the total number of pages was a few million.
Rossen: I can send you a link to a page that didn't meet the
criteria (below), but we couldn't figure out the behavior,
though the content suggested the pattern would occur.
<Rossen> http://api.solvemedia.com/papi/_puzzle.js
Rossen: Inside that JS file they're over-riding.
Rossen: So, given the low count of content that might be
exhibiting that pattern, I think we're okay to change the
behavior and monitor content issues.
florian: As I said, Firefox has that behavior and no compatibility
issue has been reported.
Rossen: I'm okay with the behavior as proposed.
glazou: Any objections to the change?
RESOLVED: Change the behavior of setProperty() according to last
week’s proposal following Rossen’s approval
glazou: I suggest we make some blog posts on w3c.org and post this
change on your personal blogs to make sure those few
people affected know about it.
Empty string value <media-query> or not
----------------------------------------
<glazou> http://lists.w3.org/Archives/Public/www-style/2014Sep/0427.html
florian: We have the behavior change in MQ 4 which isn't
intentional so I think it's okay to revet. MQ couldn't do
an empty string but it now can.
florian: Having the MQ be the empty string used to not be okay,
but the current spec suggests it evaluates as true, so we
should revert.
TabAtkins: I think I agree, I think I accidentally put a question
mark in there. But you can't have a comma with nothing
around it because that's disallowed in the grammar
right now. They must be omitted.
florian: But if they're separating the empty string it's not
considered un-ambiguous?
TabAtkins: It's not. You must omit a comma if it's not separating
two things.
florian: So the current spec is correct but is odd.
TabAtkins: We should remove the question mark.
fantasai: I think it's best if we are explicit rather than relying
on unconventional implicit behavior in a spec somewhere
else.
TabAtkins: I'm stressing we cannot have commas with nothing
between them.
zcorpan: There's no grammar for MQ, It's an algorithm
TabAtkins: That's right because it has to handle rejection.
florian: So I'd like two resolutions. Remove the question and make
it explicit that the MQ list can be an empty list.
TabAtkins: That should be def by the algorithm.
<zcorpan> http://www.w3.org/TR/mediaqueries-4/#mq-list
"An empty media query list evaluates to true."
florian: It's implicitly defined by the algorithm. There's nothing
that forbids you from having an empty list, but it
doesn't explicitly say it can be empty.
TabAtkins: I'm fine with a note that it can be an empty list.
florian: Does anyone like the behavior?
zcorpan: There is some behavior, but I don't mind changing that.
florian: The place were we say how to evaluate it says you can
evaluate to true, but there is no explicit mention in the
section about how to parse it.
RESOLVED: Allow empty string in <media-query>
animation-fill-mode and running/complicated animations
------------------------------------------------------
<glazou> http://lists.w3.org/Archives/Public/www-style/2012Mar/0445.html
sylvaing: Basic question is what happens when it's updated by
scripts.
sylvaing: We answered part of the question when you update
animation property while it's running.
sylvaing: The other question was let's say you have...your
animation is running through a delay and you have a
backwards fill and then you update your fill mode, we
never really said anything about if fill mode is
affected. I assume it should be but I wanted to check.
<dbaron> I agree it should just update.
TabAtkins: Yeah, that should be updated and the have appropriate
effect. You would stop backwards filling and not have
an affect until the delay run out.
sylvaing: I couldn't think of a situation it would be awkward.
sylvaing: No objections?
RESOLVED: animation-fill-mode applies whenever it's updated
CSSOM-view behavior of matchMedia
---------------------------------
<glazou> http://lists.w3.org/Archives/Public/www-style/2014Sep/0354.html
glazou: This came from the mailing list from Boris, it wasn't
discussed or replied to so I picked it up for the call.
zcorpan: The order of events is something I plan to define. It
will hook into requestAnimationFrame machinery when
there's something for it to hook to.
zcorpan: The iframes is defined in HTML that they should have a
0 by 0 viewport.
<zcorpan> "If a Document is in a nested browsing context, it is
expected to be positioned and sized to fit inside the
content box of its browsing context container. If a
browsing context is not being rendered, it is expected
to have a viewport with zero width and zero height."
<zcorpan> https://html.spec.whatwg.org/multipage/rendering.html#the-page
TabAtkins: Is there any other queries that matter here? I don't
think so. I think the HTML statement answers the second
question.
dbaron: You said you were planning to hook into
requestAnimationFrame machinery?
zcorpan: Yes. That's what we want to do for recite events.
dbaron: Something needs to account for flushing as well. If
something causes a layout flush it could have an effect
outside of requestAnimationFrame.
zcorpan: Good point.
glazou: So zcorpan do you want to take an action to reply to
Boris?
<zcorpan> action spieters to reply to Boris' e-mail
* trackbot is creating a new ACTION.
<trackbot> Created ACTION-655 - Reply to boris' e-mail [on Simon
Pieters - due 2014-10-08].
Review documents moved to note or gutted note
---------------------------------------------
glazou: Bert sent a message. Anything to say about it?
krit: One comment about the DOMmatrix to make it as an earlier
version of Geometry Interfaces.
glazou: Anything else to say about the documents themselves or the
publications?
TabAtkins: I haven't fully reviewed, but expect it'll be fine.
glazou: These are the docs we decided to put aside.
glazou: That's all I have for today. Is there anything else to
discuss? If not, everyone can have an extra 30 minutes for
their day.
Many: 30 more minutes is great!
glazou: Thank you very much!
