00:23:57 [fantasai]
Transforms, bugs from 11 to 6

00:24:21 [fantasai]
plh: Decided to move faster, but this is the result
00:24:33 [fantasai]
plh: Only 5 bugs fixed for Transforms, 4 for Transitions, 25 for Animations
00:24:45 [fantasai]
plh: Animations is more than 50% better
00:24:56 [fantasai]
dbaron: some metrics are a little funny. Went through bugs, most deferred to next level
00:24:59 [fantasai]
plh: Why not in LC?
00:25:02 [fantasai]
dbaron: Because 2 left
00:25:51 [fantasai]
plh: Fact is, drafts still not in LC despite controversylast year
00:26:09 [fantasai]
plh: If we look at priorities from December 2011, these are top 3 drafts: css3-background, css3-ui, css3-values
00:26:12 [fantasai]
plh: Still in this cycle
00:26:33 [fantasai]
plh: Think css3-background still held up on implementation issues and tests
00:26:39 [fantasai]
plh: css3-ui went backwards rather than forwad
00:26:43 [fantasai]
plh: css3-values went forward
00:26:46 [fantasai]
plh: One metric, not only one
00:26:55 [fantasai]
plh: Last fall, CSS chairs committed a survey
00:27:18 [fantasai]
plh: In terms of priorities, top 5 were flexbox, transforms, animations, conditional rules, transitions
00:27:54 [fantasai]
plh: Coremob profile
00:28:29 [fantasai]
plh: CSS2.1, MQ, Selectors 3, Color, Flexbox, Transforms, Animations, Transitions, CSS3 Text, CSS3 Fonts, CSS3-backgrounds and Borders, CSS3 Images, CSS3 Values, CSS Device Adaptation, CSSOM
00:29:32 [fantasai]
plh: Normative references HTML5.0
00:29:50 [fantasai]
plh: Fonts, Images, Values, Selectors 4, CSSOM, CSSOM View, css3-ui, Style Attr, Fullscreen (?)
00:30:58 [fantasai]
plh: Some of this can be tweaked
00:31:10 [fantasai]
plh: But some, e.g. View Module, can't break the dependency
00:32:06 [fantasai]
plh: Style Attributes
00:32:12 [fantasai]
fantasai: Style Attributes stuck on one failed test
00:32:17 [fantasai]
plh: Is it important test?
00:32:19 [fantasai]
fantasai: No.
00:32:22 [fantasai]
plh: Then send a PR request soon
00:33:00 [fantasai]
glazou: Whatever you do, browser vendors will implement and ship it. What's the point of breaking the dependency?
00:33:25 [fantasai]
glazou: Browser vendors will implement, ship, try for workable interop, and the spec describing the behavior of the current market will not be available
00:33:29 [fantasai]
glazou: I find it a little bit sad
00:33:41 [fantasai]
glazou: We had this discussion in AC form, chairs, wrt what is a normative reference
00:33:56 [fantasai]
glazou: I said a spec like HTML5, which is based on living standard, needs an intermediate status between informative and normative
00:34:01 [fantasai]
glazou: That is another way of solving your issue
00:34:19 [fantasai]
glazou: If I take that list, to finish everything including tests, is enough work for this WG for the entire year
00:34:28 [fantasai]
glazou: You want us to do everything by 2014?
00:35:02 [fantasai]
glazou: Each member of this WG has individual strategy and priority. if I read your slides, I think you forget it.
00:35:11 [fantasai]
dbaron: Another problem is that REC track doesn't reflect how industry really works
00:35:17 [fantasai]
dbaron: Talk of reforming REC track for a while
00:35:45 [fantasai]
plh: Several ways to approach this. One is to remove dependencies from HTml5
00:36:03 [fantasai]
plh: Third question is what does it mean to be normative ref for HTML5
00:36:18 [fantasai]
plh: Some of those references, perhaps part referenced by HTMl5 is perfectly stable and implemented
00:36:37 [Koji]
Koji has joined #css
00:36:53 [glazou]
sgalineau, let me get the lash
00:37:06 [fantasai]
fantasai: you could solve most of this is to allow REC to normatively reference CR, treating PR like transitional phase just like LC.
00:37:19 [fantasai]
fantasai: This is relatively minor change to the process, would solve the problem.
00:37:30 [fantasai]
plh talks about stability
00:37:53 [fantasai]
dbaron: This is a discussion in the TAG list
00:38:01 [fantasai]
dbaron: I think the way W3C manages normative references is broken
00:38:11 [fantasai]
plh: Do believe this has process problems
00:38:15 [glazou]
sgalineau, sure :-)
00:38:27 [fantasai]
plh: If I look at F2F agenda, this is list of things that were on the agenda
00:38:29 [glazou]
sylvaing, and I will make sure plh understands that, no worries
00:39:37 [fantasai]
plh projects some questions
00:39:47 [fantasai]
1. Are we getting the right balance between day-to-day borwser implementers needs and what's needed?
00:39:53 [fantasai]
2. What's happening with Fall 2012 Priorities?
00:40:01 [fantasai]
3. Will CSS prevent HTML5 from moving to REC by 2014?
00:40:07 [fantasai]
4. What is WG expectation for its next Charter?
00:40:37 [fantasai]
plh: Last, main question we have,
00:40:50 [fantasai]
plh: This group needs to be rechartered, what's the expecations?
00:41:26 [fantasai]
glazou: First one, you should define better what's needed. What's needed for who? This WG? Other WGs? The Press? I don't care about the Press. We make technology for billions of people. I don't care about their opinion. We should make sure everythign works.
00:41:37 [fantasai]
plh: browser vendors are the deciders in this WG
00:41:41 [fantasai]
s/plh/glazou/
00:41:55 [fantasai]
glenn: We have input from others
00:42:06 [fantasai]
TabAtkins: input, yes, but ultimately what browsers implement is what we spec
00:42:21 [fantasai]
glazou: 2nd point, TTA and Flexbox were highest priorities during most of our conference calls during 12 last months
00:42:40 [fantasai]
plh: Only 6 bugs?
00:42:49 [fantasai]
glazou: Do you have any idea how complex these bugs are?
00:42:56 [fantasai]
glazou: Take a look. Don't rant.
00:43:12 [fantasai]
glazou: 3rd point, well, the day the HTMLWG pings us to tell us they need that spec to be a REC, maybe it will change
00:43:31 [fantasai]
glazou: I told HTMLWG and W3C more than a year ago that we have problems with normative refs of HTML5. No response.
00:43:43 [fantasai]
glazou: WG expectation, I don't know. We did not discuss next charter yet
00:43:49 [fantasai]
glazou: Mine is to reduce the nubmer of specs we're working on
00:44:01 [fantasai]
glazou: Priorities can change a lot, and strategies can change a lot, over 2 years.
00:44:13 [fantasai]
glazou: E.g. Firefox was not in mobile space before. now they are working a lot on apis
00:44:26 [fantasai]
glazou: If I knew what was going to happen in CSS world 2 years from now, would be billionnaire
00:44:40 [fantasai]
glazou: So, do some cleanup, try to serve best CSS and the Web, help the HTMLWG if we can. But don't know if we can solve everything.
00:44:50 [fantasai]
glazou: Date of 2014 has been set by HTMLWG without looking at the dependencies.
00:45:08 [fantasai]
glazou: After choosing date, look at dependencies. It is not fair.
00:45:26 [fantasai]
TabAtkins: Even if we ignore dependencies, there is no way HTML5 can hit REC in 2014 without bending rules.
00:45:36 [fantasai]
TabAtkins: You're going to need like a million tests. it's not going to happen in 1.5 years.
00:45:49 [fantasai]
glazou: They lowered expectations.
00:46:01 [fantasai]
TabAtkins: By honestly reaching REC like everyone else does, will need to lower what it means to be REC.
00:46:19 [fantasai]
TabAtkins: Doesn't make a difference if we are a process-holdup. They have a process-holdup anyway.
00:47:14 [fantasai]
glenn: I don't agree with Daniel's characterization of how this group should work. Should take into account people who are using our specs, including ppl who normatively reference our specs.
00:47:20 [fantasai]
glenn: Think it's impractical perspective
00:47:32 [fantasai]
glenn: Would encourage us to not take that we work in a vacuum
00:48:07 [fantasai]
glenn: Of course, since volunteer activity, depends on people putting their energy into specs customers care about. Should request customers to bring resources to WG if what we do isn't funded.
00:48:22 [fantasai]
glazou: One of the largest users is Ebooks. And we have an acceptable cooperation with IDPF
00:48:31 [fantasai]
glazou: I think not perfect, but acceptable cooperation.
00:48:40 [fantasai]
glazou: They send us requests, they discuss CSS on their group.
00:49:02 [fantasai]
Bert: You and I are working on it, but not rest of WG
00:49:28 [fantasai]
[discussion of css3-page, css4-page]
00:49:37 [fantasai]
glazou: Where is HTMLWG to discuss with us their needs?
00:49:46 [fantasai]
glenn: Problem is communication
00:50:15 [fantasai]
glenn: I find it easier to ping users, outside W3C, than to ping some other committees.
00:50:29 [fantasai]
s/glenn/glazou/
00:51:51 [fantasai]
[discussion about cross-wg communication and HTML5 date]
00:52:08 [fantasai]
plh: If you tell me none of those specs reach REC by 2014, that's one kind of input
00:53:08 [fantasai]
...
00:53:20 [fantasai]
dbaron: Why do members care about pushing to REC?
00:53:25 [fantasai]
dbaron: Doesn't have any benefit for us
00:54:02 [fantasai]
...
00:54:18 [fantasai]
TabAtkins: REC and interop don't have a strong correlation
00:54:38 [fantasai]
plh: That's one reason, other people have other reasons
00:54:47 [fantasai]
dbaron: It's the reason why people here do the work.
00:55:18 [fantasai]
plh: You're trying to get the documents perfect before REC. You won't get there.
00:55:41 [fantasai]
glazou: Documents that don't move now are blocked on difficult technical issues (other than style attr)
00:55:49 [fantasai]
glazou: Open issues for TTA are really complex
00:56:07 [fantasai]
glazou: Question of availability of people. Only a few experts on each topic.
00:56:15 [fantasai]
glazou: Even if a large group, made of subgroups. You seem to forget that.
00:56:45 [jdaggett]
i do think we lack the ability to prioritize some specs
00:57:09 [jdaggett]
we seem to work as a group on whatever individual members are interested in working on
00:57:11 [fantasai]
Bert: Why don't we finish things we promised to finish 5 years ago?
00:57:19 [fantasai]
glazou: Ask them! (gestures to WG)
00:57:50 [jdaggett]
and that effectively crowds out work on other things
00:57:52 [fantasai]
...
00:58:17 [fantasai]
TabAtkins: Can't go to PR without testing everything in the spec
00:58:20 [myakura]
myakura has joined #css
00:58:25 [fantasai]
glenn: No, don't need to test everything in the spec
00:58:35 [fantasai]
TabAtkins: Then I have no idea what you mean by test suite.
00:59:02 [fantasai]
plh: I've never seen browser vendor that has full test suite for everything they implement
00:59:04 [jdaggett]
why don't you need to test what's in the spec?!? that makes no sense
00:59:30 [fantasai]
...
00:59:41 [fantasai]
dbaron: Philippe admits that REC doesn't need to be perfect
00:59:50 [jdaggett]
existing browsers have lots of legacy stuff
00:59:53 [fantasai]
dbaron: One problem we have with process is that we want to maintain specs, and continue to maintain them as ppl bring up issues
01:00:06 [fantasai]
dbaron: Problem with process is that it's much harder to update a REC
01:00:14 [jdaggett]
but the quality of testing efforts is vastly improved over the past five years
01:00:47 [fantasai]
plh: Don't see why
01:00:53 [fantasai]
plh: Just need to have a test for each change
01:01:02 [fantasai]
plh: You are setting a bar for REC that is way too high
01:01:11 [fantasai]
dbaron: You act as though publishing a doc is trivial thing
01:01:29 [fantasai]
dbaron: Publishing CR requires editor to spend days pinging various people for permission
01:01:36 [fantasai]
dbaron: It's not worht a week of my time to get document published on /TR
01:02:21 [fantasai]
glazou: Pages of spec:
01:02:23 [fantasai]
12 pages for CSS1
01:02:29 [fantasai]
258 for CSS21
01:02:36 [fantasai]
4000 for CSS3
01:03:10 [fantasai]
glazou: It's a lot of work
01:03:47 [fantasai]
Bert: Seems like we always want things to be in flux
01:04:04 [fantasai]
TabAtkins: Want to always be refinining / correcting things.
01:04:17 [fantasai]
TabAtkins: 100% stability is an illusion
01:04:34 [fantasai]
[discussion of bureaucracy]
01:04:47 [fantasai]
[and how to allocate resources to it]
01:05:51 [fantasai]
glazou: 2 passing implementations for each testable assertion
01:06:01 [fantasai]
glazou: That's the way it should be. Otherwise test suite has no value.
01:06:15 [fantasai]
glazou: I understand HTML5 has different requirements. And I agree with Tab that that test suite has no value. It's just marketing.
01:06:22 [fantasai]
/just/pure/
01:07:28 [fantasai]
...
01:07:38 [fantasai]
jet: Sounds like W3C wants REC documents
01:07:50 [fantasai]
jet: Group says cost to REC is too high, and CR is good enough
01:08:02 [fantasai]
jet: Perhaps the product expected of this group should change
01:08:20 [fantasai]
plh: If I go to AC and say CR is the new REC, AC will not happy
01:08:52 [fantasai]
Bert: We used to have no testing requirement
01:08:56 [fantasai]
Bert: process changed
01:09:06 [fantasai]
glazou: So process can change. These people are telling you process needs to change.
01:09:53 [fantasai]
plh: You're saying we should have no test suite requirement, other say they want more testing requirement
01:11:06 [fantasai]
..
01:11:22 [fantasai]
glazou: HTML has lower expectation because want to release fast, because marketing impact and press, releasing HTML5
01:11:28 [dbaron]
LC of css3-conditional took 28 days from publication request (November 15) to publication (December 13)
01:11:45 [dbaron]
so it's not just CRs
01:11:47 [fantasai]
glazou: You lowered the bar to meet that date
01:12:04 [fantasai]
dbaron, that was largely because I didn't notice that the document wasn't published when it was requested to be published
01:12:25 [fantasai]
dbaron, and so wasn't able to follow up and get it published the next day
01:12:42 [fantasai]
...
01:13:08 [fantasai]
jdovey describes IDPF process, which is fast and loose
01:13:21 [dbaron]
it didn't help that there was a 5 day delay from 15th to when it was supposed to be published, and then a week from noticing that it wasn't published to it actually being published
01:13:54 [fantasai]
liam: Pragmatic, and on programming end pragmatism is imporant. But e.g. governmental standards requirements are different
01:13:56 [isra]
isra has joined #css
01:14:00 [fantasai]
glazou: These 4 questions
01:14:18 [fantasai]
glazou: To answer these 4 questions, we need to know what you want.
01:14:24 [fantasai]
glazou: What does W3M want about the priorities?
01:14:33 [fantasai]
glazou: What do you think we should do wrt dependencies
01:14:42 [fantasai]
dbaron: Why does W3M have to make those decisions
01:14:50 [fantasai]
glazou: Don't say they make decisions, just want their input.
01:15:48 [fantasai]
plh: ...
01:15:58 [fantasai]
r12a: IDPF has been really keen on vertical text and ruby
01:16:08 [fantasai]
r12a: Ruby CSS module is way off the bottom of the scale in terms of work being done
01:16:16 [fantasai]
r12a: I know that's partly because ppl don't ahve time to work on it
01:16:30 [fantasai]
r12a: But what's the process the WG has, for discussing with IDPF, and allowing them to raise what they want
01:16:40 [fantasai]
glazou: Question I discussed with Markus Gylling
01:16:44 [fantasai]
glazou: We don't have a real process
01:16:59 [fantasai]
glazou: We discuss technical issues sometimes, but not really how can we answer, address improtant requests from their point of view.
01:17:02 [fantasai]
glazou: E.g. ruby, which is best example
01:17:06 [fantasai]
glazou: We have no one
01:17:40 [fantasai]
glazou: When we tell them we have no resources to work on that right now, they say they'll wait. Members unwilling ot join this group
01:17:54 [fantasai]
ivan: digital publishing interest group ...
01:18:11 [fantasai]
ivan: Not chartered to develop sepcs, but may come up with priorities and requirements, and maybe find ppl to do the work here.
01:18:32 [fantasai]
r12a: What is the process for CSSWG for re-evaluating priorities and discussing stakeholder requirements?
01:20:26 [fantasai]
...
01:20:52 [fantasai]
dbaron: Need to communicate that we don't have resources, and let them work on it if they want to put those resources in.
01:21:11 [fantasai]
Bert: ...
01:21:17 [fantasai]
glazou: Strategy of the market changes
01:21:28 [fantasai]
Ivan: Whole issue of membership fee etc.
01:21:42 [fantasai]
Ivan: Let's say 3-4 ppl form task group within this wg to develop technolgy XYZ
01:21:47 [fantasai]
Ivan: Do you have structure of task forces?
01:21:55 [fantasai]
Ivan: What's the decision procedure?
01:22:11 [fantasai]

01:25:14 [fantasai]
dbaron: to really do it right
01:25:36 [jdaggett]
maybe because shoving code for a feature into webkit before ironing out the spec is not a constructive approach...!
01:25:39 [fantasai]
dbaron: Having a patch in WebKit is different from having a standard that can be interoperably implemented and everyone agrees with

dbaron: Don't see how you can implement a requirements document.
01:26:45 [fantasai]
dbaron: If you want a technical spec, need to describe what the technology is
01:26:55 [fantasai]
jdovey: Desribes how characters should be laid out

TabAtkins: Rewriting from grammar approach to parser approach
02:01:33 [jerenkrantz]
http://dev.w3.org/csswg/css-syntax/
02:01:40 [fantasai]
TabAtkins: grammar tried to match everything, not just well-formed things, and was too complicated and didn't quite handle everything anyway
02:01:56 [fantasai]
TabAtkins: Tokenizer, then Parser
02:02:08 [fantasai]
TabAtkins: Includes hooks for other specs to include a certain type of thing
02:02:18 [fantasai]
TabAtkins: I would like to review some things with group, then ask for FPWD
02:02:34 [fantasai]
TabAtkins: Probably as correct as 2.1 at this point
02:03:17 [fantasai]
TabAtkins: WebKit uses augmented grammar to parse, and it's horribly broken.
02:03:42 [fantasai]
TabAtkins: Wanted to go over changes from 2.1
02:03:49 [fantasai]
TabAtkins: First batch of changes are about parsing
02:03:59 [fantasai]
TabAtkins: 2.1 defined some interesting rules for detecting @charset
02:04:17 [fantasai]
TabAtkins: Brought into line with charset handlign in rest of platform
02:04:29 [dbaron]
we're reviewing http://dev.w3.org/csswg/css-syntax/#changes as of 4ce7b66b553a
02:04:39 [fantasai]
r12a: Does that mean it doesn't handle UTF16
02:04:56 [fantasai]
TabAtkins: Can use UTF16 by having BOM, but won't recognize @charset
02:05:13 [fantasai]
fantasai: How interoperable is this, compared to 2.1?
02:05:30 [fantasai]
TabAtkins: Dropping some obscure encodings probably ok, since implementations' don't support them
02:05:51 [fantasai]
TabAtkins: Wrt web-compat, shoudl be just fine
02:06:01 [fantasai]
TabAtkins: dropping things like EBCDIC
02:06:15 [fantasai]
liam: Did you check for corporate intranet stuff?
02:06:27 [fantasai]
TabAtkins: I think likelihood of EBCDIC is close to zero

Bert: You can't remove thing
02:07:37 [fantasai]
Bert: This is supposed to be stable
02:07:43 [jerenkrantz]
FWIW, IBM keeps ensuring that EBCDIC support is working in httpd. Someone at IBM would be able to give an idea of its reach.
02:07:50 [fantasai]
Bert: We promised not to make versions to CSS, just to add things
02:08:06 [fantasai]
Bert: Don't think we should remove features just because not used on the Web
02:08:11 [fantasai]
Bert: Remove features when they're wrong.

[discussion of changes]
02:08:58 [fantasai]
Bert: Not an argument to keep on making mistakes
02:09:15 [fantasai]
r12a: When HTML5 did some charset stuff, wanted to do it to stop people using non-UTF-8
02:09:21 [fantasai]
r12a: Is that your motivation?
02:09:34 [fantasai]
TabAtkins: Highly sympathetic to moving to UTF-8, but main issue is making this much simpler
02:10:01 [fantasai]
glazou: If all style sheets were UTF-8, would be much easier for authoring environments
02:10:44 [SimonSapin]
q+
02:10:56 [fantasai]
dbaron: Checking for UTF-16 rules were widely tested
02:11:15 [fantasai]
dbaron: We changed recently. Ran into no web-compat problems, but ran into certification problems.
02:11:27 [glazou]
ack SimonSapin
02:11:36 [fantasai]
SimonSapin: Would like to point out that this is only about @charset. Can do anything you want with HTTP headers
02:12:12 [fantasai]
SimonSapin: Also, relevant part of CSS2.1 gives a table of byte patterns. Allows UAs to remove some, or to add some
02:12:22 [fantasai]
dbaron: Sorry, what I said is opposite.
02:12:46 [fantasai]
dbaron: When we implemented what this draft sayse, and this caused us to start passing th GCF certification suite
02:13:18 [fantasai]
dbaron: It has a test of a UTF-16 file that claims an encoding name that doesn't exist
02:13:36 [fantasai]
r12a: What did you say was the first step in detecting charset?
02:13:43 [fantasai]
r12a: Thought we changed so that BOM is first
02:13:51 [dbaron]
the thing I was just describing was https://bugzilla.mozilla.org/show_bug.cgi?id=859706 being fixed by https://bugzilla.mozilla.org/show_bug.cgi?id=796882
02:13:57 [fantasai]
TabAtkins: BOM is checked first by decoding algorithm, before @charset
02:14:06 [fantasai]
TabAtkins: this list finds the fallback encoding
02:14:50 [fantasai]
...
02:15:04 [fantasai]
r12a: Do you forbid use of @charset in UTF-16 documents?
02:15:08 [fantasai]
TabAtkins: No, you just ignore it
02:15:19 [dbaron]
er, actually, the encoding name does exist but it's an alias for UTF-16BE, while the file is UTF-16LE
02:15:22 [fantasai]
TabAtkins: Never invalid to put @charset
02:15:38 [fantasai]
plh: What if UTF-16 without BOM but with @charset?
02:15:47 [fantasai]
TabAtkins: Defer to encoding standard...
02:15:53 [fantasai]
r12a: you can do it, but say you shouldn't
02:16:53 [fantasai]
s/plh/plinss/
02:17:25 [fantasai]
TabAtkins: Specifying anything other than ascii-compatible encoding is not useful
02:17:34 [fantasai]
r12a: Since already defined, why not keep them?
02:17:39 [fantasai]
r12a: I share bert's unease here
02:17:49 [fantasai]
r12a: I agree it would be great to move to UTF-8 everywhere
02:18:21 [fantasai]
TabAtkins: If implementations get bug reports on things should ask for standard to be updated
02:18:29 [fantasai]
plinss: Would prefer to include this table
02:18:38 [fantasai]
plinss: I know there are implementations that implement that entire table, because i made one
02:18:52 [fantasai]
TabAtkins: Gecko doesn't anymore, don't think WebKit does either
02:19:09 [fantasai]
dbaron: Gecko only implemented ascii-compatible cases and UTF-16 cases.
02:19:09 [glazou]
WeasyPrint implements that table
02:19:15 [fantasai]
dbaron: never did UTF-32 or EBCDIC
02:19:26 [fantasai]
dbaron: Might've done UTF-32 long ago, but that cod eripped out a long time ago
02:19:36 [fantasai]
dbaron: ripped out support for UTF-32 entirely
02:19:57 [fantasai]
TabAtkins: My preferred approach is to keep it as-is right now. if there's a problem, we'll see bug reports
02:20:01 [fantasai]
TabAtkins: Alter as necessary
02:20:18 [fantasai]
plinss: Not really happy with that approach. Break it and see who complains?
02:20:33 [fantasai]
TabAtkins: Don't want to include rows that browsers don't implement it
02:20:51 [fantasai]
plinss: But some that are significant
02:21:19 [fantasai]
TabAtkins: Leave this in, with an issue maybe?
02:21:30 [fantasai]
TabAtkins: Issue that we may need to add additional charset encoding patterns?
02:21:48 [fantasai]
plinss: Maybe add onto that that we're explicitly requesting feedback on this
02:21:49 [tlr]
tlr has joined #css
02:22:02 [SimonSapin]
WeasyPrint implements part of that table because I didn’t know any better. Some cursing was involved.
02:22:03 [fantasai]
plinss: Agree we probably don't need EBCDIC, and a private browser could implement that for an intranet
02:22:17 [fantasai]
plinss: But more concerned wrt UTF-16 issues
02:22:35 [fantasai]
plinss: Web is huge. Small percentage is still a lot of pages
02:22:47 [fantasai]
TabAtkins: encoding will detect
02:22:52 [fantasai]
plinss: Shouldn't be sniff it
02:23:15 [fantasai]
plinss: If there's a document that doesn't have BOM and has @charset, shouldn't be sniffing it. Should use @charset
02:23:46 [fantasai]
SimonSapin: Can also rely on HTTP headers
02:23:56 [fantasai]
plinss: We have problems e.g. in our test suite, file sthat work on the server, but not locally
02:24:20 [fantasai]
plinss: CSS should not, don't think that we require style sheet to be served over HTTP
02:25:36 [Bert]
(The issue can ask which @charset lines can be deprecated.)
02:25:53 [fantasai]
TabAtkins: Step 4, where you take charset from encoding document. Should that only work for same-origin?
02:26:54 [fantasai]
s/4/3&4/
02:27:20 [fantasai]
r12a: Value of 4 is ppl who don't understand charsets or setting http headers
02:27:50 [fantasai]
...
02:28:09 [fantasai]
TabAtkins: So, take charset from referring document only if it's same-origin. Yay/nay?
02:28:24 [fantasai]
TabAtkins: Ok, I'll say yes for now, object later
02:28:27 [fantasai]
Bert: what's issue?
02:28:45 [fantasai]
TabAtkins: Sometimes if you can force a document into a different encoding, can extract info from it
02:28:55 [fantasai]
TabAtkins: This would prevent that kind of thing
02:29:01 [fantasai]
Bert: What could you do with a style sheet in wrong encoding?
02:29:41 [fantasai]
TabAtkins: Don't have specific example, but this kind of problem has been an issue in other technologies
02:30:07 [fantasai]
Bert: But you're only changing your own document, not someone else's
02:30:24 [fantasai]
dbaron: Suppose has wiki, where input CSS that shoudl be sanitized
02:30:39 [fantasai]
dbaron: Could have fun encoding , maybe UTF-7 or Shift-JIS or something, that can create cross-site scripting vulnerabilities
02:31:05 [fantasai]
dbaron: Encode control characters for programming languages as benign ascii chars
02:31:32 [fantasai]
TabAtkins: Can't give a specific attack scenario, just know there's problems in other languages

Bert: Concerned about people putting stylesheet on one server, seems to work, then moves it to other server, doesn't work.
02:32:04 [fantasai]
TabAtkins: If you have a charset problem, use UTF-8
02:33:08 [dbaron]
dbaron: Either way I'd prefer to leave an issue in there until we're confident it's stable.
02:33:21 [dbaron]

04:22:27 [Bert]
... There should not be a distinction between real italics and synthetic case.
04:22:31 [Bert]
... Bad inconsistency.
04:22:41 [Bert]

04:24:25 [Bert]
... Limited to display type, headlines etc. One line only.
04:24:44 [Bert]

04:26:45 [Bert]

04:28:01 [Bert]
jdaggett: Spec now says synth happens based on whether there is italic or not.
04:28:18 [Bert]
... Whether synth italic is good or not is separate matter.
04:28:35 [Bert]
... If we have to have synth italic, and we do, then it has to be consistent with real italic.

04:46:26 [Bert]
... It seems to be a script property.
04:46:50 [Bert]
... Adobe's Japanese fonts have italic glyphs for Latin.
04:47:01 [Bert]
... You can do tru italic with Adobe fonts.
04:47:15 [Bert]

My concerns with 1 are that there are cases that break with it, even though it is typographically better. Since the correct solution is to use an italic font, this fallback case should just be the option that works adequately in the most cases. And #2 does that: it doesn't create overlapping problems, it doesn't break multi-glyph constructs, and it doesn't break cursive scripts or fonts.

.. Difference in baseline
05:20:26 [Bert]
... Metrics same as surronfing text for Unicode superscript glyphs.
05:20:39 [Bert]
... FOnt has metrics for syntheseis
05:20:51 [Bert]
... This pb exists with Unicode code points already.
05:21:00 [Bert]
... My point is that we don't need to do anythign special.
05:21:10 [Bert]
... You get what you get in 2nd example.
05:21:17 [Bert]
... You don't get detailed control.
05:21:32 [Bert]
fantasai: The one we want is what matches the HTML example.
05:21:38 [Bert]
.. Thatos what people want.
05:21:58 [Bert]
... Take info from font, and use that to position underline.
05:22:07 [Bert]
jdaggett: That doenst match where the glyphs are.
05:22:14 [Bert]
... Cannot have magic.
05:22:24 [Bert]
... Fallback won't work.
05:22:29 [Bert]
... etrics are different.
05:22:38 [Bert]
fantasai: But it will match synthesized glyps.
05:22:46 [Bert]
jdaggett: No, not close enough.
05:22:56 [Bert]
fantasai: he bottom examples don't look right at all.
05:23:01 [Bert]
... We can get closer.
05:23:09 [Bert]
jdaggett: Just wrong in a different way.
05:23:20 [Bert]
... Adobe's font all have same metrics.
05:23:29 [Bert]
... Aling will be differne tbase don font.

jdaggett: Showis diff ebtween real superscript on left and synth version in middle.
05:24:32 [Bert]
... Baseline is not the same.
05:24:44 [Bert]
... Will have unerline in middle. Not look right.
05:24:58 [Bert]

05:25:09 [Bert]
... Text decoration same issue coming back all over again.
05:25:17 [Bert]
... We kust don't have it, it i snot available.
05:25:35 [Bert]
Leif: Can the font p[rovide metrics?
05:25:44 [Bert]
fantasai: Yes, they could.
05:26:11 [Bert]
jdaggett: Not the right answer. The metrics are meant fo rthe synth case.
05:26:25 [Bert]
... Example 22 shows that synth superscript is larger.
05:26:36 [Bert]
... Designer made it so.
05:26:44 [Bert]
... Metrics work with synth.
05:26:54 [Bert]
... Not so well fo rthe designed glyphs.
05:27:03 [Bert]
... Which is what you propose to use them for.
05:27:09 [fantasai]
I still think it's better to use those metrics than to use the base size metrics
05:27:28 [Bert]
... Complex content [...]
05:27:44 [Bert]
... It is not meant as complet ereplacement for HTML mark-up.
05:27:53 [Bert]
... There are limitations, noted in the spec.
05:28:15 [Bert]
fantasai: I'd like to edit text deco spec to say we use font metrics in font.
05:28:32 [Bert]
jdaggett: What are doing?
05:28:35 [fantasai]
glenn: I agree
05:28:42 [Bert]
... The metrics don't match what you want to sue them for.
05:29:02 [Bert]
glenn: If the font *doe* have metrics, they should be used.
05:29:14 [Bert]
... Agreed?
05:29:37 [Bert]
jdaggett: The metrics are used for synthesis.
05:29:45 [Bert]
... If you resize,
05:29:58 [Bert]
... The metrics don't matchs the actual glyphs.
05:30:16 [Bert]
... Sure, if you design a font with metrics, but that is a big "if."
05:30:22 [Bert]
.. Not common practice.
05:30:49 [Bert]
... Other comments or questions?
05:31:17 [glazou]
glazou has joined #css
05:31:18 [Bert]
Leif: Seems fantasai 's suggestion works in exmaple 22, but maybe not for subscript.
05:31:23 [Bert]
... Maybe not in gemeral.
05:31:36 [Bert]
fantasai: Metrics of base size is not any better, propbably worse.
05:31:56 [Bert]
Leif: I don't really know how fantasai 's uggestion will turn out for subscripts.
05:32:06 [Bert]
... Better result more often than not?
05:32:45 [Bert]
glenn: If font designed specs a sub or super feature, but without glyphs, you suggest we synthesize?
05:32:55 [Bert]
jdaggett: Spec ahs wording about that.
05:33:07 [Bert]
... We do include wording for fallback, we will synthesize.
05:33:28 [Bert]
... If user adds elements or images, or sub-spans, then they should use the HTML way.
05:34:01 [Bert]
... We pretty much resolved on the feature not being a complete replacement for HTML mark-up, and it shuldn't be one.
05:34:15 [Bert]
glenn: Is there consistency among UAs for fallback?
05:34:32 [Bert]
jdaggett: Nobody implemented it, no cmparison to make.
05:34:48 [Bert]
... Gecko has impl ebhind a flag, but without the fallback behavior.
05:34:55 [Bert]
glenn: Mark fallback at risk?
05:35:02 [Bert]
jdaggett: Why?
05:35:17 [Bert]
glenn: Lack of implem experience.
05:35:34 [Bert]
jdaggett: No strong case, spec is just not finsihed yet.
05:35:56 [Bert]
glenn: No early implementers either.
05:36:10 [Bert]
glazou: Can the people discussing now find a compromise?
05:36:37 [Bert]
jdaggett: What do ypu want me to compromise on?
05:36:42 [Bert]
... There si nothing.
05:36:53 [Bert]
fantasai: Cannot live with John's option.
05:37:16 [Bert]
jdaggett: You're propisng magic, not a real proposal.
05:37:57 [Bert]
plinss: If metrics available, use them, but seems there are none.
05:38:20 [Bert]
jdaggett: Based on what research?
05:38:35 [Bert]
plinss: Metrics are for something else, acoording to jdaggett
05:38:54 [Bert]
... So if the metrics don't exist, [...]
05:38:56 [glazou]
Rossen, and jdaggett a longsword ?-)
05:39:10 [Bert]
fantasai: But if they exists it will be right, and otherwise they will be slighty off.
05:39:30 [Bert]
plinss: Fine with a note in text decoration about if there are metrics.
05:39:37 [Bert]
fantasai: We have to put the underline somewhere.
05:39:46 [Bert]
... Which metrics do you use.
05:40:00 [Rossen]
glazou, Nooo just a swiss knife
05:40:11 [Bert]
... Just because Unicode glyohs have this pb, doesn't mean we have to copy the pb.

liam: Proposal:
05:40:27 [Bert]
... WebFonts WG has liasion with ISO Opentype
05:40:34 [Bert]
... Chair of WG.
05:40:44 [Bert]
... Ask them about a new metric.
05:40:55 [Bert]
... Not invent something ourslelves.
05:41:16 [Bert]
jdaggett: Shors delay, are you joking?
05:41:38 [Bert]
liam: If we have to wait for a new feature, that would be long. But not long to ask the question.
05:41:47 [Bert]
jdaggett: We have been trhought this.
05:42:12 [Bert]
Liam: In that case redraw suggestion.
05:42:21 [Bert]
plinss: Still useful to talk to Opentype.
05:42:34 [Bert]
glenn: Truetype has different tables.
05:42:55 [dbaron]
glenn: ... bsln (Truetype) vs BASE (OpenType)

... Are we too specific to OpenType.
05:43:00 [Bert]
jdaggett: [missed]
05:43:06 [dbaron]
jdaggett: superscript metrics are in OS2 table
05:43:13 [Bert]
glenn: Asking because you also mention baseline offsets.
05:43:19 [Bert]
... Just wondering...
05:43:45 [Bert]
... You and Elika get together.
05:44:17 [Bert]
glazou: strawpoll.
05:44:43 [fantasai]
fantasai: Proposal is for when superscripts or subscripts are decorated, use superscript/subscript metrics to position decoration
05:44:52 [Bert]
plinss: Are you taling about synth *and* non-synth case?
05:44:57 [dbaron]
jdaggett: The text underline follows the surrounding glyphs (for both in the synthesized case and the actual glyphs case)
05:45:01 [fantasai]
fantasai: jdaggett's proposal is that instead, use the metrics of full-size glyphs
05:45:05 [Bert]
jdaggett: Yes, behave same way, nortmal baseline, not shifted.
05:45:23 [Bert]
TabAtkins: [pointing to figures]
05:45:49 [Bert]
dbaron: jdaggett only refers to Unicode codepoints, not to the HTML version.
05:46:23 [Bert]
fantasai: That means underline the whole thing as the full size chars,
05:46:24 [dbaron]
fantasai: in the example, jdaggett wants the OpenType version to match the Unicode version rather than the HTML ersion
05:46:42 [Bert]
fantasai: People do not undelrine the degree char, but they do underline superscripts.
05:47:20 [Bert]
TabAtkins: jdaggett 's proposal is the lower half of the current projected screen.
05:47:43 [Bert]

05:48:54 [Bert]
jet: Does this hold up LC on fonts?
05:49:03 [Bert]
fantasai: No, it is an issue for text decoration.
05:49:28 [Bert]
jet: We should really resolve this, cannot keep on fighting.
05:50:17 [Bert]

06:13:59 [Bert]
jdaggett: [looking for URL]
06:14:34 [Bert]
... fantasai posted that it should be different, ensued a thread. Tab prposed a subclass of grtouping rule.
06:14:53 [Bert]
... And then make each feature block another subclass.
06:15:07 [Bert]
... I'd like to gauge group's opinion.

06:15:54 [Bert]
dbaron: Mixed feelings
06:16:19 [Bert]
... If it looks like an 2rule it should behave like an at rule. On other hand an awful lot of pieces to make.
06:16:46 [Bert]
fantasai: I know Tab has comments, wait for him to come back into the room.
06:17:02 [Bert]
jdaggett: Let me look for Tab's stuff.

http://lists.w3.org/Archives/Public/www-style/2013May/0596.html
06:17:34 [Bert]

06:17:55 [jdaggett]
@swash {
06:17:56 [jdaggett]

}
06:17:59 [jdaggett]
}
06:18:36 [Bert]
dbaron: Hesitant to reopne discussion, but makes me wonder if there is too many levels of nesting.
06:18:48 [dbaron]
@font-feature-values Bongo { @swash swishy 1; @swash wavvy-gravy 2; }
06:18:52 [Bert]
... Why in that example, not like this [see above]
06:19:13 [Bert]
jdaggett: That was original proposal, but we switched to more at-rule-like version.
06:19:23 [Bert]
fantasai: Both are at-rules.
06:19:35 [Bert]
plinss: Don't see why not a group rule.
06:19:44 [Bert]
... But don't want ot separate i/f classes

06:20:06 [Bert]

... Or maybe a string
06:20:49 [Bert]

06:20:55 [Bert]
plinss: Makes sense.
06:21:07 [Bert]
fantasai: [question]
06:21:16 [Bert]
jdaggett: [bad sound]
06:21:23 [fantasai]
fantasai: Didn't you have a simplifying proposal, that we could expand later?
06:21:26 [Bert]
... My proposal is at-rule with nothing in it.
06:21:41 [Bert]
TabAtkins: [explains proposal]
06:21:55 [Bert]
fantasai: could go with that, and than make a css3 font extensions spec.

... feauture value blocks in spec,
06:31:12 [Bert]
... fantasai says they should just be called at-rules.
06:31:21 [Bert]
... But I think they are different.
06:31:28 [Bert]
... User defined identifiers.
06:31:38 [Bert]
... The way they compound is an issue.
06:31:54 [Bert]
... I tink it is important to day this is different form other at-rules, with descriptors.
06:32:09 [Bert]
Tab: That is just about terminology.
06:32:22 [fantasai]
whttp://www.w3.org/TR/CSS21/syndata.html#at-rules
06:32:25 [jerenkrantz]
is the resolved proposal the one from: http://lists.w3.org/Archives/Public/www-style/2013May/0781.html ?
06:32:32 [Bert]
... It starts with an 2-keyword, all at-rules ar edifferent already. so it is just an at-rule.
06:32:34 [fantasai]
" At-rules start with an at-keyword, an '@' character followed immediately by an identifier (for example, '@import', '@page').
06:32:37 [fantasai]
An at-rule consists of everything up to and including the next semicolon (;) or the next block, whichever comes first. "

06:33:11 [Bert]
fantasai: CSS 2 calls it an at-rule when it starts with an at-keyword.
06:33:24 [Bert]
jdaggett: Yes, parses like an at-rule.
06:33:33 [Bert]
... Shoild we not call it something else?
06:33:36 [jerenkrantz]
stearns: Thanks.
06:33:47 [Bert]
TabAtkins: Within the spec, call it what you want.
06:33:57 [Bert]
... Whatever makes sense. But technically it is an at-rue.
06:34:06 [Bert]

... To match HTML, NUL chars are converted into replacement chars.
06:37:17 [Bert]
... Don't know why HTML does it, but at least it means CSS inside HTML is same as CSS in a file.
06:37:34 [Bert]
fantasai: Replacement char is valid identidier char, could be weird.
06:37:44 [Bert]
TabAtkins: Nobody puts NUL in a style sheet....

dbaron: I can send comment about that, later.
06:53:50 [Bert]
TabAtkins: The only relevance of my change os for mixture of digits and digits.
06:54:08 [Bert]
... CSS 2.1 created invalid range, which was then thrown away.
06:54:17 [Bert]
... Fnal behavoir is the same..
06:54:29 [Bert]
fantasai: why chage. Let's not do tokenaztion changes.
06:55:01 [Bert]
TabAtkins: Easier to parse.

bert: depnds on parsing suystem.
06:55:25 [Bert]
tab: In mine token is always correct.
06:55:47 [Bert]

06:56:02 [Bert]
plinss: Then I'm not so bothered.
06:56:29 [Bert]
Bert: But why change it.
06:56:34 [Bert]
fantasai: Current is fine.
06:56:46 [Bert]
dbaron: I don't believe the change is undetectable.
06:56:55 [fantasai]
Gecko implements the 2.1 definition
06:56:57 [Bert]
Tab: Maybe in future.
06:56:58 [dbaron]
I also don't mind the change.
06:57:20 [Bert]
plinss: That's is why it gets important.
06:57:39 [Bert]
TabAtkins: But I have to write more text to accept the old syntax.
06:58:22 [Bert]
glenn: Font family quoted string that is empty: seems not prohibited.
06:58:33 [Bert]
dbaron: You might have a font with that name.
06:58:44 [Bert]
glenn: Far fetched, but itis an answer...
06:58:54 [Bert]
TabAtkins: Not a sybtax question, question for fonts.
06:59:24 [Bert]
plinss: Whether you can test the unicode range syntax difference now is not the question.
06:59:57 [Bert]
... You're change maybe gives us more flexibility to not add white space in future properties.
07:00:09 [Bert]
fantasai: Not really, some unicode rabges end in digits, so not helpful.
07:00:34 [Bert]
dbaron: No, not helpful, there are too many different kinds of unicode range tokens. Often require a space anyway.
07:00:46 [Bert]
plinss: Then the change is irrelevant.
07:01:31 [dbaron]
I agree the change is safe, and I agree it's pointless.

... Wouldn't call it valid.
07:04:38 [Bert]
plinss: It is not gray. We know when to throw a property away.
07:05:18 [Bert]
TabAtkins: New attribute matching operatore are imported into tokenizer.
07:07:43 [Bert]
Bert: The new attribute operatores are not tokens, they are two tokens.
07:07:50 [Bert]
Tab: But selectors defiend them as tokens.
07:08:05 [Bert]
Bert: No, selectors defiend how to parse selecotrs, not how to parse css.
07:08:57 [Bert]
plinss: Don't agree with bert's argument, but accept the point.
07:09:35 [Bert]
... They will always be atoken if we take tab's proposal, and we remove the possibility of useing them as as part of differnet symntax
07:09:46 [Bert]
TabAtkins: : Reduces ossibilities, yes.
07:09:56 [Bert]

07:11:27 [Bert]
... Because it clashes with namespace selectors.
07:11:45 [Bert]

07:11:55 [Bert]

... Have no bug reports.
07:19:50 [Bert]
fantasai: You're parsing invalid stuff anyway.
07:20:14 [Bert]
dbaron: It is about parens *after* the piece that already makes it invalid.
07:20:39 [fantasai]
fantasai^: So if someone found a problem with your behavior, they'd be fixing their style sheet, not filing a bug

Bert: I don't care about error recovery, si I'm fine, but be aware that you change the measning of existing style sheets.
07:29:18 [Bert]
Tab: Yes, we had no bug reports, so don't think it is a problem.

... Error recovery not defined.
07:30:05 [Bert]
... So I'm defining error recovery.
07:30:11 [Bert]
dbaron: I'd like to review this more.
07:30:36 [dbaron]
dbaron: Did you fix the cases where CSS 2.1 didn't allow CDO and CDC in some places?
07:30:41 [Bert]
... What about CDO CDC?
07:32:06 [Bert]
Bert: As long as it is only about error recovery for CDO/CDC in more places, fine with me.
07:32:25 [fantasai]
ScribeNick: fantasai
07:32:34 [fantasai]
An+B notation
07:32:50 [fantasai]
TabAtkins: The notation is incompatible with CSS tokenization
07:33:13 [fantasai]
TabAtkins: For example, 5n-3 tokenizes as a dimension
07:33:26 [fantasai]
TabAtkins: But we need to split it up into 5, n, -, 3
07:33:39 [fantasai]
TabAtkins: Implementations right now have to guess where it ends ... so far easy because of close-parens
07:33:46 [fantasai]
TabAtkins: Then reserialize and reparse
07:33:54 [fantasai]
TabAtkins: Wanted to redefine an+b in terms of CSS tokens
07:34:01 [fantasai]
TabAtkins: I can get it almost identical to defined behavior
07:34:09 [fantasai]
TabAtkins: But there are two changes
07:34:16 [fantasai]
s/two/two small/
07:34:20 [fantasai]
dbaron: Think the WS change is not small
07:34:35 [fantasai]
TabAtkins: First change is that +n or +n+2 ok
07:34:40 [fantasai]
TabAtkins: but + n not ok
07:34:53 [fantasai]
TabAtkins: Similarly -n vs. - n
07:35:06 [fantasai]
TabAtkins: Issue is that when you tokenize these, +n becomes 2 tokens
07:35:11 [fantasai]
TabAtkins: so does + n
07:35:26 [fantasai]
TabAtkins: -n and - n tokenize differently
07:35:38 [fantasai]
TabAtkins: Property grammars ignore white space
07:36:08 [fantasai]
TabAtkins: So can't distinguish
07:36:12 [Bert]
fantasai: I don't think ths needs to change.
07:36:18 [fantasai]
dbaron: Tab just made up this idea of property grammars
07:36:24 [fantasai]
TabAtkins: propdef grammars don't talk about ws
07:36:39 [fantasai]
dbaron: I don't want to change the space rules here
07:37:20 [fantasai]
TabAtkins asks how parsers work
07:37:30 [fantasai]
dbaron says Gecko has a flag about whether ws is paid attention to
07:37:54 [fantasai]
In WebKit, apparently WS tokens are omitted automatically when you ask for a token
07:38:04 [fantasai]
fantasai: how can be possible in selectors?
07:38:04 [dbaron]
div*p
07:38:33 [fantasai]
Bert: Also numbers, numbers with a sign can't have space between number and sign
07:39:07 [fantasai]
side discussion of NUMBER tokens
07:39:54 [fantasai]
dino: White space is gone by the time you try to parse things
07:40:09 [fantasai]
TabAtkins: How do you parse calc() and selectors then?
07:40:37 [fantasai]
krit: ... something about whitespace and ident
07:41:14 [fantasai]
RESOLVED: No spacing changes in An+B syntax
07:41:33 [krit]
s/something about whitespace and ident/something about whitespace and ident in WebKit/
07:41:53 [fantasai]
TabAtkins: +n-\33
07:42:04 [fantasai]
TabAtkins: parses as "+" "n-3"
07:42:12 [fantasai]
TabAtkins: which looks like An+B
07:42:55 [fantasai]
TabAtkins: So, change to allow escaping in cases where the tokenization derives from idents
07:43:02 [fantasai]
TabAtkins: Which probably matches implementations
07:43:46 [fantasai]
Bert: So escaping before reparsing?
07:43:49 [fantasai]
TabAtkins: no reparsing
07:43:51 [jerenkrantz]
RRSAgent: make minutes
07:43:51 [RRSAgent]
I have made the request to generate http://www.w3.org/2013/06/06-css-minutes.html jerenkrantz
07:44:02 [fantasai]
TabAtkins: escaping was handled much earlier in parsing process
07:44:13 [fantasai]
TabAtkins: Disallowing it would create a major layering violation
07:44:29 [fantasai]
TabAtkins: By the time you care about whether something is an+b, you've lost the original representation
07:44:52 [fantasai]
plinss: So this scenario produces a valid ident, with content "n-3" as the string
07:45:08 [fantasai]
plinss: How does that become an an+b?
07:45:22 [fantasai]
dbaron: Spec says if you have ident "-n-" followed by digits, then it's valid an+b
07:45:36 [fantasai]
dbaron: I think this is far saner than the route we went down with URL, where we made it a separate token
07:45:58 [fantasai]
TabAtkins: All three of these are equivalent, except they tokenize completely different
07:46:02 [fantasai]
n - 3
07:46:09 [fantasai]
n- 3
07:46:11 [fantasai]

07:50:55 [fantasai]
TabAtkins: So, can I publish yet?
07:51:32 [fantasai]
dbaron: I think the efforts here are worthwhile, but I would like to review the bracket-matching part before FPWD. I haven't had time yet
07:51:52 [fantasai]
dbaron: I'm worried because I think once we have FPWD, people will only look at this, not at CSS2.1
07:52:11 [fantasai]
dbaron: So if we don't fix something now, it will b ehard to fix later
07:52:24 [fantasai]
dbaron: And I'm worried because it was originally reverse-engineered from the worst implemenation (WebKit)
07:52:27 [fantasai]
TabAtkins: I won't deny that.
07:53:07 [fantasai]
Bert: I can't understand this draft, apart from the railroad diagrams. Can you put more of those, or put grammar rules?
07:53:17 [fantasai]
TabAtkins: I think I have diagrams for everything in the spec
07:53:55 [fantasai]
fantasai: does your spec define what a style rule is, what a declaration is, what these things mean?
07:53:58 [fantasai]
TabAtkins: yes
07:53:59 [fantasai]
SimonSapin: No, it doesn't
07:54:31 [fantasai]
fantasai: I think we need to add such a section, since this part of 2.1 logically belongs here.

There is a big box, which represents the thing that contains the fragmentainers.

07:58:26 [fantasai]
stearns: These could be regions, pages, column boxes, whatever
07:58:42 [fantasai]
stearns: Crucial thing is that fragmented flow has an article, which contains a paragraph, and there's a break at some point in the paragraph
07:58:49 [fantasai]
(represented by boxes A and P)
07:59:01 [fantasai]
stearns: Issue is when you click in one of the fragments of the P
07:59:07 [fantasai]
stearns: The fragmentainer never hears about it
07:59:30 [fantasai]
stearns: The event goes out from P to A to the outer box, skips FC boxes

dino: You said it doesn't matter, but is FC1 or FC2 regions, or columns... is A a child of that?
08:00:35 [fantasai]
stearns: In overflow fragments A would not be a child of either container, would be a child of outer box
08:00:43 [fantasai]
dbaron: In overflow fragments not that distinction, just the one level
08:01:06 [fantasai]
stearns: If I said :nth-fragment(2):hover, I want that fragment container to respond to hovering over this part of the paragraph, and not respond to hovering over the other part of the paragraph
08:01:13 [fantasai]
Bert: Could have :hover on the outer box
08:01:18 [fantasai]
stearns: I want the container to change
08:02:24 [fantasai]
stearns: Only when it's hovered inside, not when the other fragment is hovered inside
08:02:31 [fantasai]
stearns: And in Regions these can be different elements
08:02:45 [fantasai]
dino: In A have one region element you're flowing into. Events don't get seen by region element
08:02:46 [Bert]
(DIV:hover::slot(fc2) {... highlight... }.)
08:02:48 [fantasai]
stearns: No
08:03:00 [fantasai]
dino: you can't write a rule that says ::region:hover
08:03:05 [fantasai]
stearns: right, and I want to
08:03:06 [fantasai]
dino: me too
08:03:21 [fantasai]
stearns: Regions has an API that allows you to determine which region got clicked.
08:03:28 [fantasai]
stearns: Doesn't work for hover but works for click events
08:03:33 [Bert]
(Forget what I just said.)
08:03:47 [fantasai]
stearns: That workaround only works for events, doesn't work for :hover styling
08:03:58 [fantasai]
stearns: But that workaround also doesn't work for fragmented elements
08:04:28 [stearns]
http://wiki.csswg.org/spec/css3-regions/user-event-handling
08:04:43 [fantasai]
stearns: There are two proposals for handling this
08:04:48 [fantasai]
stearns: First is for fragmented flows in general
08:04:53 [fantasai]
stearns: When you have event bubbling in a fragmentation context
08:05:11 [fantasai]
stearns: Event goes up through the chain as normal to the fragmentation root
08:05:19 [fantasai]
stearns: The thing that contains the content that is fragmented
08:05:29 [fantasai]
stearns: At that point, the fragment container is inserted in the bubbling
08:05:45 [fantasai]
stearns: And the bubbling continues with whatever contains the fragment container, up through the hierarchy.
08:06:11 [fantasai]
dbaron: Are you talking about event bubbling because you want to change :hover, or because you want to change what event handlers get?
08:06:14 [fantasai]
stearns: Yes.
08:06:23 [fantasai]
jdaggett: Issue on columns as well
08:06:30 [SimonSapin]
s/Yes./Yes. Both./
08:06:39 [fantasai]
stearns: Once we get to point of having addressable columns, can be done for columns
08:06:40 [Zakim]
-jdaggett
08:06:50 [fantasai]
stearns: If you want to know what page an even twas on, would have page inserted in event/style loop
08:06:53 [TabAtkins]
s/jdaggett/djovey/
08:07:02 [fantasai]
stearns: I'm actually not sure whether bubbling for CSS :hover is actually defined anywhere
08:07:02 [TabAtkins]
s/djovey/jdovey/
08:07:07 [fantasai]
stearns: I assume it does the same
08:07:14 [fantasai]
dbaron: It's not really bubbling, but it's defined
08:07:15 [Zakim]
+[IPcaller]
08:07:23 [jdaggett]
zakim, ipcaller is me
08:07:23 [Zakim]
+jdaggett; got it
08:07:42 [fantasai]
http://dev.w3.org/csswg/selectors4/#the-hover-pseudo
08:07:46 [fantasai]
"The parent of an element that is :hover is also in that state. "
08:07:58 [jdaggett]
was there a question?
08:08:09 [jdaggett]
i'm muted...
08:08:12 [fantasai]
stearns: One way to solve this, is, in a fragmentation context, insert the fragmentainer at the appropriate spot
08:08:18 [fantasai]
stearns: One more thing in the appropriate spot
08:08:42 [fantasai]
dino: If it's a region, then does it bounce back to the ancestor chain or go up the region's ancestors?
08:08:47 [fantasai]
stearns: Goes up the region's ancestors
08:09:03 [fantasai]
This essentially circumvents the element's own ancestor chain
08:09:18 [fantasai]
TabAtkins: Problem you're describing is virtually identical to problem with Shadow DOM and events
08:09:28 [fantasai]
TabAtkins: Shadow DOM can rearrange content in a similar way
08:09:37 [fantasai]
TabAtkins: Regions is slightly more general issue, but can be safely generalized under this as well
08:09:50 [fantasai]
TabAtkins: Don't know precise details of what we do, but if you want details will have to ask Dmitry, who just went home
08:09:59 [fantasai]
stearns: Shadow DOM describes it as DOM manipulation
08:10:04 [fantasai]
stearns: follow reordered DOM hierarchy
08:10:12 [fantasai]
TabAtkins: After reordering and following up
08:10:33 [fantasai]
TabAtkins: Things that aren't in the Shadow DOM have no way of telling that the event passed through the Shadow DOM
08:10:46 [fantasai]
stearns: That's very important to shadow DOM, not so important here.
08:10:58 [fantasai]
TabAtkins: Could break things if you add pseudos you didn't expect
08:11:11 [fantasai]
stearns: It will continue to multicol element, just one added stop

08:11:41 [fantasai]
... regions ...
08:12:03 [fantasai]
fantasai: In case of regions, you might wind up not hitting your ancestors, because going up region's ancestor chain now.
08:12:16 [fantasai]
fantasai: whereas other cases, you always walk up all your ancestors, just might make extra stops along the way
08:12:47 [fantasai]
stearns: If you go through email thread linked from wiki
08:12:59 [fantasai]
stearns: Went through number of iterations tryng to figure out how to preserve event bubbling chain
08:13:02 [fantasai]
stearns: or dealing with this osmehow
08:13:08 [fantasai]
stearns: everything got way too messy
08:13:43 [fantasai]
stearns: Once you've put content into this fragmented flow, makes more sense to me for events to follow region's ancestor chain
08:13:59 [fantasai]
fantasai: Depends on what you're trying to do
08:14:35 [fantasai]
fantasai: Depends on how much you're scrambling the tree, and how much you are handling events locally vs. talking to things higher in the document tree
08:14:43 [fantasai]
dino: Think it's very confusing to go up region chain
08:14:51 [fantasai]
dino: If you wrote selector parent-element > child-content
08:14:56 [fantasai]
dino: Expect that selector to apply
08:15:08 [fantasai]
dino: wrote parent-element:hover > child-content to work
08:15:15 [fantasai]
dino: But break that expectation
08:15:30 [fantasai]
stearns: ...
08:15:40 [fantasai]
stearns: But named flow, taking boxes from parent, putting them over here
08:15:51 [fantasai]
stearns: these boxes should be ones responding to user events because you made that disassociation
08:15:57 [fantasai]
dbaron: I find it really weird to have events not follow the DOM
08:16:02 [fantasai]
dbaron: They're a DOM structure
08:16:20 [fantasai]
dbaron: And I think separation of content and presentation makes it really weird for box-tree structure to mess with DOM structure
08:16:28 [fantasai]
stearns: Have a response to hover styling?
08:16:35 [fantasai]
dbaron: I think hover styling is separate from events
08:16:51 [fantasai]
TabAtkins: Can be easier to handle :hover going two directions up the tree, than events going up the tree
08:17:03 [fantasai]
TabAtkins: Could do complicated thing now with pseudo-classes, rather than events
08:17:22 [dbaron]
dean: what happens with elementFromPoint()?
08:17:38 [dbaron]
dbaron: it depends if there's content at that point in the region -- you get the most deeply nested thing
08:17:56 [fantasai]
dino: Want to understand why :hover and events could be different
08:18:11 [fantasai]
dbaron: :hover is a CSS concept
08:18:22 [fantasai]
dino: Base don mouse events
08:18:29 [fantasai]
dbaron: That's changed over time. It happens to be true now
08:18:45 [fantasai]
plinss: We have whole dichotomy of things like mouse events, that deal with geometry of presentation
08:18:53 [fantasai]
plinss: These fire at the DOM tree, kindof broken
08:19:12 [fantasai]
dbaron: We could have another type of mouse event that doesn't bubble, but that you fire at everything in that geometry
08:19:19 [fantasai]
dbaron: We do sortof have that for mousover and mouseout
08:19:36 [fantasai]
stearns: Another solution is to add a mode to pointer-events property
08:19:50 [fantasai]
stearns: So you could say for e.g. relpos'd box, events will follow box tree
08:20:04 [fantasai]
Rossen: Going through iterations, another idea for adding region as a separate target
08:20:29 [fantasai]
stearns: Other mode, other solution is to have this switch, where for certain elements that you choose, you have the event just run through the visual layers
08:20:46 [fantasai]
TabAtkins: element with fragment parent, goes to fragment parent rather than real parent?
08:20:59 [fantasai]
stearns: Goes to whatever's displayed underneath it, which in fragment case would be fragmentainer
08:21:08 [fantasai]
dino: One option is following DOM tree
08:21:13 [fantasai]
dino: second is following box tree
08:21:18 [fantasai]
dino: Third is following painting order
08:21:26 [fantasai]
stearns: Second solution is not doing the middle event
08:21:33 [fantasai]
stearns: Right now pointer-events can be normal, they go up the DOM tree
08:21:46 [fantasai]
stearns: Can say pointer-events: none;, which ignores pointer events
08:21:55 [fantasai]
stearns: Switch would trigger just painting order
08:22:06 [fantasai]
stearns: You'd get the relpos box and whatever is underneath it
08:22:51 [fantasai]
TabAtkins: So third one is elementsFromPoint() and walk that list
08:23:06 [fantasai]
plinss: Where are you setting this switch?
08:23:23 [fantasai]
The target of the element will decide on the path of the event
08:23:37 [jdaggett]
followup on the subscript/superscript metric discussion, here's the example from hamburg:
08:23:38 [jdaggett]
http://people.mozilla.org/~jdaggett/tests/subsupermetrics.png
08:23:40 [fantasai]
dino: If you did something like this, set it on ancestor, does ???
08:24:00 [fantasai]
dino: Doing propagation based on painting order is quite complicated, because implementations might forget exactly the order for perf reasons
08:24:17 [jdaggett]
rssagent, make minutes
08:24:45 [fantasai]
some concerns about implementation all around
08:25:04 [fantasai]
TabAtkins: We have elementsFromPoint() already, regardless need to be able to get at that list
08:25:10 [leif]
rrsagent, make minutes
08:25:10 [RRSAgent]
I have made the request to generate http://www.w3.org/2013/06/06-css-minutes.html leif
08:25:31 [fantasai]
stearns: For pointer-events: none, still need to have that info as well; that requires one answer, this case needs the whole stack
08:25:55 [ivan]
ivan has joined #css
08:26:15 [fantasai]
TabAtkins: For the case that shoudl hop through the fragment order, should that just be a generic box order movement?
08:26:27 [fantasai]
TabAtkins: Anything else outside fragmentation would also affect that
08:26:34 [fantasai]
stearns writes out options
08:26:38 [fantasai]
1) Fragment container insertion
08:26:42 [fantasai]
2) Painting order switch
08:27:16 [fantasai]
stearns: for #1, issue of where to put the fragmentation container in the order
08:27:29 [fantasai]
stearns: Painting orde rswitch is more general, works for other positioning things as well, also works for any type of fragment conatiner
08:27:40 [fantasai]
TabAtkins: Do have to define that the event path includes fragment containers
08:27:48 [fantasai]
TabAtkins: So can't lean on that concept entirely
08:27:53 [fantasai]
fantasai: We don't have those eyt
08:27:57 [fantasai]
s/eyt/yet/
08:28:13 [fantasai]
TabAtkins: So, suggesting go with paint order one for now, possibly also introduce box tree
08:28:22 [fantasai]
plinss: what's diff between paint order and box tree?
08:28:31 [fantasai]
TabAtkins: paint order just go through layers under that point
08:28:48 [fantasai]
TabAtkins: box tree would jump from element to its containing block, not hit things underneath it necessarily
08:29:07 [fantasai]
Rossen: ...
08:29:20 [fantasai]
Rossen; Final transformed position, thus actual behind element is the furthermost ?
08:29:33 [fantasai]
Rossen: Subtle difference, but makes a difference once you factor in transforms
08:29:41 [fantasai]
Rossen: and relpos I guess
08:29:47 [fantasai]
TabAtkins: Fine with leaving out box-tree
08:30:16 [fantasai]
asking about who implements elementsFromPoint()
08:30:26 [fantasai]
krit: Suggested couple months ago, not sure that anyone implements it
08:30:32 [fantasai]
dbaron: Dont' see it in CSSOm or CSSOM View
08:31:29 [fantasai]
...
08:32:49 [Bert]
(Other issue: If '::foo' is a region, then '::foo:hover' would be the expected synntax to select it in hover state... but that syntax is not allowed by css3-selectors.)
08:32:53 [fantasai]
stearns: So if I'm reading the room correctly, people leaning towards pointer-event switch
08:34:32 [fantasai]
Bert raises issue against Selectors 4
08:34:40 [fantasai]
::first-line:hover e.g. makes sense, and would work
08:34:48 [fantasai]
::first-line:nth-child() doesn't make sense
08:34:58 [fantasai]
fantasai points out that each pseudo-element has to define what it accepts
08:35:15 [fantasai]
Bert points out that we need to define which selectors are invalid (cause selector to be thrown out) and which simply don't match anything
08:35:46 [fantasai]
</aside>
08:36:10 [fantasai]
dbaron: This is pretty scary, don't think we should make a change without checking with WebAPI folks
08:36:58 [fantasai]
RESOLVED: Work on pointer-events: elements-from-point solution
08:37:09 [fantasai]
that will walk the elementsFromPoint chain instead of the ancestor chain
08:37:25 [fantasai]
stearns: One of the issues...
08:37:37 [fantasai]
stearns: Shapes specification
08:37:44 [fantasai]
stearns: Whether we should allow shapes from rendered content
08:37:52 [fantasai]
stearns: Think we should, but would like to push it to level 2
08:38:00 [plinss]
http://www.w3.org/mid/CDD64C22.3AD08%25stearns@adobe.com
08:38:06 [fantasai]
stearns: CSS Shapes atm defines getting shape from an image, and from shapes from basic shape syntax, and I think that is sufficient for first level
08:38:19 [fantasai]
stearns: already pushed off SVG elements. Would like to push off rendered content for now.
08:38:23 [fantasai]
dbaron: what is it?
08:38:37 [Rossen]
http://lists.w3.org/Archives/Public/www-style/2013May/0389.html
08:38:45 [fantasai]
stearns: E.g. you have an A rendered large, or repeated background, etc.
08:38:55 [fantasai]
stearns: I think it's useful thing to do, but very complicated
08:39:20 [fantasai]
Rossen: Think original motivation for that was around time when we were proposing shapes to begin with. One of the use cases was a type of article that becomes a shape
08:39:31 [fantasai]
Rossen: extracting shape from rendered text
08:39:38 [fantasai]
Rossen: drop-cap, with tight-wrap around it
08:39:53 [fantasai]
Rossen: That was original motivation. Agree it's advanced feature for current level of spec
08:40:00 [fantasai]
Rossen: If we want to move spec quicker and have big bang for our money
08:40:09 [fantasai]
Rossen: Having simpler shapes, easy to define
08:40:26 [fantasai]
Rossen: That would hold implementations for quite some time.
08:40:46 [fantasai]
fantasai: Makes sense to me. I would prioritize SVG shapes over this feature.
08:40:50 [fantasai]
TabAtkins: me too
08:40:57 [fantasai]
stearns: Any objections to moving this over?
08:41:02 [fantasai]
plinss: Images?
08:41:14 [fantasai]
stearns: No, they stay. That's biggest ask aside from SVG
08:42:01 [fantasai]
dino: At what resolution do you derive the shape?
08:42:04 [fantasai]
...
08:42:08 [fantasai]
stearns: We'll solve that as we get to it
08:42:27 [fantasai]
...
08:42:48 [fantasai]
dino: You might have an image that's displayed 100x100 but it's 10000x10000 image, as you zoom you see more pixels, shape might change and suddenly impact layout
08:43:24 [fantasai]
TabAtkins: other changes due to not aligning to pixel boundaries too
08:43:39 [fantasai]
dino: Need to define exactly the operation you use, masking whatever
08:43:41 [fantasai]
stearns: agree
08:43:57 [fantasai]
liam: Could get almost effect of text-wrapping around A, by making path in SVG and wrapping around it
08:44:07 [fantasai]
stearns: could make polygon with basic shape syntax
08:44:22 [fantasai]
stearns: Aren't guaranteed to get the glyph you're expecting, though
08:44:44 [fantasai]
stearns: Other issue, in spec, that says ...
08:44:51 [fantasai]
krit: ???
08:45:30 [fantasai]
RESOLVED: Move contours from rendered content to next level
08:45:45 [fantasai]
stearns: Issue on spec on shapes from images
08:46:10 [fantasai]
stearns: Security concern of being able to determine contours of alpha channel of image
08:46:24 [fantasai]
TabAtkins: Could extract cross-domain info
08:46:29 [fantasai]
TabAtkins: Reasonably efficient attack, too
08:47:08 [fantasai]
plinss: Imagine image you're putting in page is bar graph of your account balances of your bank
08:47:33 [fantasai]
Same-origin or CORS
08:47:47 [fantasai]
TabAtkins: Work with Anne, he'll tell you what to do correctly.
08:48:14 [dbaron]
annevk is working on http://fetch.spec.whatwg.org/ which makes these things easier to define
08:48:15 [TabAtkins]
krit: Same-origin may not protect you if open redirectors are used.
08:48:26 [TabAtkins]
TabAtkins: That is always a concern for *everything* that's SOR.
08:48:56 [TabAtkins]
dino: I'm not sure SOR is enough.
08:49:14 [fantasai]
ScribeNick: TabAtkins
08:49:16 [TabAtkins]
dino: [describes an attack that I didn't understand]
08:49:30 [TabAtkins]
stearns: You're assuming that a site is wrapping content around a secure image.
08:49:59 [TabAtkins]
dino: I'll describe the scenario better in the mail list.
08:50:27 [TabAtkins]
krit: For SVG images, that's one of the reasons SVG images aren't allowed to reference images from another domain.
08:51:37 [Zakim]
-jdaggett
08:52:06 [TabAtkins]
TabAtkins: The SVG issue is different. That's about beinga ble to detect when an image is viewed, by including an external ref in that image.
08:52:15 [TabAtkins]
krit: It's a different attack, but same scenario.
08:52:23 [TabAtkins]
[please describe the attack better]
08:52:43 [TabAtkins]
stearns: New topic. The idea is that we should add floats to exclusions, so we have one way of wrapping things around each other.
08:53:11 [TabAtkins]
stearns: I propose we dont'. Floats work within the wrapping context, and are their own crazy thing.
08:53:24 [TabAtkins]
TabAtkins: Does that mean we lose the "exclusions can auto-avoid each other" switch?
08:53:30 [TabAtkins]
stearns: No, this is unrelated.
08:53:41 [TabAtkins]
Rossen: The two things are kind of joined...
08:53:53 [TabAtkins]
stearns: No, they're disjoint. They work differently - it's defined in the spec.
08:54:15 [TabAtkins]
Rossen: INline content at the same level as the float will avoid both floats and exclusions, but exclusions penetrate much higher.
08:54:33 [TabAtkins]
Rossen: So they really are disjoint in terms of geometry, and in the stack they have different behavior.
08:54:53 [TabAtkins]
Rossen: So keeping them separate is way easier. From an impl point of view, I approached keeping them together with floats, but it started becoming a mess quickly.
08:55:46 [TabAtkins]
Bert: Is this just an impl issue?
08:55:58 [TabAtkins]
stearns: No, spec issue. The spec says how to construct the wrapping context.
08:56:15 [TabAtkins]
stearns: The spec defines that floats create areas that content avoid.
08:56:34 [TabAtkins]
stearns: Question is to keep that, or to try and fully harmonize floats with exclusions so they act identically (rather than just similarly).
08:57:04 [TabAtkins]
Rossen: It will hypothetically allow you to have an impl with just exclusions, no floats.
08:57:31 [TabAtkins]
Bert: If you can explain how they'd behave differently, it would be appreciated.
08:57:46 [TabAtkins]
stearns: In the wrapping behavior, they behave the same, for a single flaot and a single exclusion.
08:58:45 [TabAtkins]
RESOLVED: Close the flaot/exclusion harmonizing issue.
08:59:26 [TabAtkins]
Topic: Syntax editor
08:59:33 [TabAtkins]
TabAtkins: I propose adding Simon as Syntax co-editor.
08:59:44 [TabAtkins]
RESOLVED: Simon Sapin is Syntax co-editor.
09:00:22 [TabAtkins]
RESOLVED: Exclusion wrapping context does not include floats. (Clarifying two resolutions ago.)
