Given the lack of any other comments, and the fact that we appear to basically implement the spec (although we haven't quite kept up with the latest changes, e.g., the addition of initMessageEvent), I'm inclined to vote in favor without comments.

Sorry for not getting this out for people to have a look at sooner. -David Regarding the HTML5 specification, my organization: (X) suggests changes, but supports publication as a W3C Recommendation whether or not the changes are adopted (your details below). Comments: General comments: We support publication as a Recommendation although there are surely many details in the specification that are wrong, either because the specification disagrees with itself or because it disagrees with what is needed to make an implementation that can suceed in the market. The level of coverage in the test suite is not enough to avoid that. These errors will be found over time. The harm these errors cause will be determined by how the W3C community handles the HTML specification in the future: * Statements in the specification that are inconsistent or incompatible with what Web content requires should keep being fixed in the future, just as they have been while developing HTML5 up to this point. That those statements are part of a W3C Recommendation should not increase the burden of proof. * Development of tests that test this specification should continue. Being declared interoperable enough for Recommendation should not stop future increase in interoperability. And this development of tests should focus on the latest specification, not on the Recommendation snapshot. To put this another way: while we support the publication of this specification as a W3C Recommendation, we do not likewise support the promotion of W3C Recommendation status as a major milestone. The process of continuous improvement, which should continue, is far more important than the snapshot. Specific actionable change proposals: (1) We would like to see the reference for the URL specification point to the CG snapshot, as proposed in http://lists.w3.org/Archives/Public/public-html/2014Sep/0061.html (2) While it would be helpful to have the recommendation contain pointers to current and future work (e.g., have a more useful Latest Editor's Draft link that's likely to point to the editor's draft for future HTML specification development), and a useful explanation in the status section of the differences between the recommendation and the editor's draft. Usage: [X] produces products addressed by this specification [X] expects to produce products conforming to this specification [X] expects to produce content conforming to this specification [X] expects to use products conforming to this specification When the W3C's and WHATWG's HTML specifications differ, we tend to follow the WHATWG one.

Producing tests seems clearly in line with the Mozilla mission, and provides a way for Servo to have a near-term impact on other Mozilla products such as Gecko. This is particularly the case when Servo is implementing parts of the platform that have poor interop in existing browsers. It should also allow Servo itself to move faster by making it more likely that the implementations you make are actually web-compatible on the first try, rather than needing many cycles of redesigns and fixups. The new HTML parser is an example of a complex feature that has a large existing testsuite and which I am therefore confident will work in a web-compatible way (at least for static documents) as soon as it lands.

Hi David, On 20/09/2014 02:23 , L. David Baron wrote: One of the open issues being raised in this review is the status of the spec's normative reference to the URL specification. The specification currently references http://www.w3.org/TR/url/ ; it might be possible for us to suggest that it instead reference either http://url.spec.whatwg.org/ or https://whatwg.org/specs/url/2014-07-30/ (although if we did so, it would probably be best for somebody to raise the issue elsewhere in addition to it just being part of our review). I think the world would be better place if we could pacify the WHATWG/W3C relationship. Of course, I realise that this can be a relatively ironic statement to make in the context of a vote on publishing W3C HTML, but I am making it nevertheless because I believe that baby steps can help get us there. I was hoping that we could simply reference WHATWG URL as a (small) token of good faith and normalisation, adding a small cobblestone to pave the way to cooperation. Sadly, this has proven contentious. But as with all polarised discussions, it is hard to tell if there is genuine opposition or just a small group of angry agitators. Therefore, if you believe that making such a reference would be a good step forward, I would encourage you to make a comment in that direction (note that we can reference both the latest version and the snapshot). You don't need to raise the issue elsewhere, it has already been raised, burnt, buried, and zombified a few times over.

Obviously I agree that good testing of implementations is key to interoperability. Talking about testing in the context of the snapshot reads like pretending that we should treat the snapshot as something other than a lawyer point of reference for the purpose of the PP. Of course, if something in the spec is wrong and we implement something else, maybe the PP isn't that strong on that point, but it still seems worthwhile to get PP commitment for the stuff that happens to be right or close enough to right for lawyer purposes. I also agree that we should encourage vendors to create and run shared tests for the web technologies that we implement. I am substantially less convinced that tying these tests to the spec lifecycle makes sense. The W3C Process encourages people to think of interoperability as a binary condition; either implementations are interoperable or they are not. This leads to ideas like the CSS WG's rule that two implementations must pass every test. On the face of it this may appear eminently sensible. However the incentives for testing under such a regime are not well aligned with the goal of finding bugs in implementations; in essence people are encouraged to write as many tests as are needed to satisfy the letter of the rules but to make them all as shallow and unlikely to find bugs as possible to avoid causing unwanted holdups in the specification process. I would much prefer to have a testsuite written by people making a genuine effort to find errors in implementations even if the result is that no one passes every single test. These effects of tying tests to snapshots are clearly harmful. We should track EDs for testing and implementation instead of targeting known-stale snapshots. My concrete suggestion is that we, as an organisation, work to achieve parity between the tests we require to ship our own code and those we release in ways that can be used to support a spec and, more importantly, those that can be used verify that different implementations match up. In practice this means not writing tests in Mozilla-specific formats, and making sure that we have a way to upstream tests that we've written. Making this process as low-overhead as possible is something that I'm working on. Yes. Furthermore, the test damage from snapshots lessens if the people who do the work to write the tests contribute tests written to EDs instead of snapshots.

I would much prefer to have a testsuite written by people making a genuine effort to find errors in implementations even if the result is that no one passes every single test. I couldn't agree more. In fact, part of my hope when we were setting up Web Platform Tests was that having a continuously updated test suite instead of a bunch of hasty rushes to get enough coverage of a spec for it to ship would help people realise that specs should be handled in a similar manner too. I can't say it has brought about a revolution yet, but it has certainly helped change minds. It's hard to argue against a continuously updated test suite. It's hard to imagine that such an animal wouldn't find spec bugs in addition to implementation bugs. It's hard to justify knowing about bugs and not shipping an update.

At this point Mozilla has proven to be a huge contributor to the WPT project (with Opera's massive release of tests another notable help) but we have not yet seen comparable commitments from the other browser vendors.

The WG turned into an unproductive, bureaucratic, nightmare and succeeded in driving out their core constituency leaving the remaining participants to debate topics of little consequence. If we were to complain about the lack of testing for HTML, we would be told in no uncertain terms that we (or at least the WG) had agreed to the Plan 2014 which explicitly chose to forego testing in certain areas, and specification accuracy, in favour of shipping at a defined time. This idea of shipping on a date-based schedule isn't actually obviously bad, as long as you set the expectations correctly, which is something the W3C will get wrong. It would indeed be nice if W3C would embrace this fully and move to a WHATWG-style model with no eratta but a spec kept continually up-to-date in the areas where there is a need for change, and absolute rigidity in the areas where reality dictates that change is impossible. However moving them there is a longer term goal that seems to be met with extreme resistance from people who haven't fully grasped how shipping a web browser works. Well, my plan is to move pretty much there in a matter of months.

It may contain mistakes or things may have changed since the publication. Please make sure to check the most up to date document BLAH [with link to the whatwg spec] before implementing any features.

At the heart of the idea is the notion that different constituencies may have different needs, some needing a (relatively) stable snapshot while others need a (relatively) up to date document. Additionally, we can't presume to know who would need which when. The usual distinction made between lawyers and implementers is overly simplistic (e.g. a lawyer could need either, implementers of some specific tools might need a snapshot for some reason). Instead we can try something crazy new and trust readers not be radically dumb by providing them with the information they need to make up their minds. This is a quick draft of the idea, it's very much open to evolution. ## Usage of this Document Web standards are available in two flavours: snapshots, which are immutable versions made at a point in time and guaranteed never to change, and live versions which capture as much as possible the latest state of the technology and are intended to be continuously maintained and kept up to date. Which version you should rely on and reference depends on your needs. If your specific situation demands am unchanging document, understanding that it is likely to contain defects that have been addressed elsewhere, then you will want to use the snapshot. If however you require a document that is as up-to-date as possible, then the live version is for you. If in doubt, we recommend you rely on the live document. This document is a snapshot document. For the live version, please visit [link]. One suggestion in this space is to also drop the style sheet from snapshots to make it clear that they're not nice things to use (as in https://whatwg.org/specs/url/2014-07-30/). I understand the thinking but I am concerned that it could introduce issues (in some cases losing information).

As for whether it's a small-group concern, I wish there was less confrontational rhetoric, so I don't want to show up to make a group of angry agitators larger Actually I was talking about the small group of people who *object* to referencing a WHATWG specification. but I think there should be a spec that defines how URLs work in a way that's well-defined realistically implementable in browser engines (and in other software that wishes to work with content that's written mainly to be consumed by browser engines). Considering how long the IETF has had to deliver such a spec but hasn't delivered and how practically infeasible it seems to get the kind of work that Anne is doing done within the framework of an IETF WG, I think Anne's spec should be given a chance without casting doubts from the start about it getting changed over motivations other that Web compatibility in a later revision. Well yes, that's pretty much my point. -- Robin Berjon - http://berjon.com/ - @robinberjon ___ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform

It's hard to imagine that such an animal wouldn't find spec bugs in addition to implementation bugs. It's hard to justify knowing about bugs and not shipping an update. Things tend to make their own way from there. That sounds like a plausible story; let's hope the truth is something close to it. However if we as an organisation really care about testing core platform features which already have an implementation in gecko, one way to achieve that would be to give someone working on Servo the explicit job of creating testsuites for the big-ticket features they implement as they implement them. That would certainly be helpful. In addition, I would note that while a shared test suite benefits everyone. At this point Mozilla has proven to be a huge contributor to the WPT project (with Opera's massive release of tests another notable help) but we have not yet seen comparable commitments from the other browser vendors. So any help you can provide in convincing people to contribute is very welcome. Yes, getting more contributions from all vendors would be a big improvement. However I think it's worth noting that others have made contributions; for example Google have contributed a number of testsuites for new technologies they are implementing. Well, my plan is to move pretty much there in a matter of months. For me that's the biggest value in putting HTML5 out of the door: it frees up a lot of flexibility (and energy) in how things are done from now on. If this happens it will be great progress. I fear there is still a lot of stop energy for large changes, but I guess trying to push them through is the only way to find out of that's actually the case. ___ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform

I think you'd get a better result by asking for agreement from all the relevant implementors that they felt that the spec was implementable. Obviously answering this question with any accuracy requires the implementor to actually put some effort into understanding the design in the context of their code, probably by implementing it. This would allow you to be less conservative (you don't have to wait for every low-priority bug to be fixed), without having to sabotage the testsuite in order to keep up the pretense those bugs don't exist at all.

Re: W3C Proposed Recommendation: HTML5
Specifically on the subject of what URL spec to reference, I think it should be Mozilla's position (which I'm willing to represent) that the W3C HTML5 spec reference the dated URL spec[1] instead of the copy/paste/modified(even if informatively) W3C WebApps URL spec.

Usually I'd just go ahead with this proposal, but given the diversity of opinions on this thread, figured I'd see what folks here thought first.

Obviously I agree that good testing of implementations is key to interoperability. I also agree that we should encourage vendors to create and run shared tests for the web technologies that we implement. I am substantially less convinced that tying these tests to the spec lifecycle makes sense. The W3C Process encourages people to think of interoperability as a binary condition; either implementations are interoperable or they are not. This leads to ideas like the CSS WG's rule that two implementations must pass every test. On the face of it this may appear eminently sensible. However the incentives for testing under such a regime are not well aligned with the goal of finding bugs in implementations; in essence people are encouraged to write as many tests as are needed to satisfy the letter of the rules but to make them all as shallow and unlikely to find bugs as possible to avoid causing unwanted holdups in the specification process. I would much prefer to have a testsuite written by people making a genuine effort to find errors in implementations even if the result is that no one passes every single test. Of course it's possible that going through the spec and making sure there is at least one test for every conformance criterion will make the testsuite good even if people are determined to produce a poor testsuite. However I strongly doubt this to be the case. Indeed I'm only aware of a handful of examples of someone setting out to write a test for every conformance criterion in a specification and ending up with a useful result. The canvas / 2d context tests are one of those cases, and that benefits from being a rather self-contained set of operations without much interaction with the rest of the platform. Even if someone took the same approach to, say, document loading tests, it is unlikely that the result would be as good because the features are much more likely to interact in unpleasant ways so that, for example, the load event and document.open might work independently but using the two in combination might break in an unexpected way. I'm also dubious that requiring a test for every assertion in the spec is a standard that we are prepared to hold ourselves to when we ship code. Since shipping code is, in the grand scheme of things, substantially more important than shipping a spec — the former affecting all our users and the latter only lawyers — it doesn't seem at all reasonable to demand that the specification is held to a higher standard. My second biggest issue is that I don't have a concrete proposal for addressing this the first issue. My concrete suggestion is that we, as an organisation, work to achieve parity between the tests we require to ship our own code and those we release in ways that can be used to support a spec and, more importantly, those that can be used verify that different implementations match up.

Making this process as low-overhead as possible is something that I'm working on. Obviously this isn't going to make a short-term difference for old features like WindowProxy. I'm not sure what to suggest for those cases given that we have de-facto shown an unwillingness to invest even relatively small amounts of effort into reviewing existing tests that could be part of the HTML testsuite for that feature [1]. In the longer term, one might hope that bugfixes will produce new testcases that could be upstreamed, and Servo might need a proper testsuite to achieve interoperability. Having said that, Servo has so far not produced a significant number of tests, which has been a little surprising as they have been implementing some of the core pieces of the platform which are indeed under-tested. I suspect this is because the skills, interests and goals of the team are around producing code rather than tests. For people making small contributions it would also be rather off-putting to be told no you can't land this fix that makes Wikipedia look better without a comprehensive testsuite for the relevant feature. However if we as an organisation really care about testing core platform features which already have an implementation in gecko, one way to achieve that would be to give someone working on Servo the explicit job of creating testsuites for the big-ticket features they implement as they implement them.
