The intent is similar to that of EventSource, which has the url attribute for a similar purpose (at least that is how I have used it). And since the checkRemotePermission() method needs to verify the permission for the same URL, it is better to have the resolved form of the URL available as an attribute, so that it's easy to call the checkRemotePermission() method for the right URL (as the absolute URL may have changed since the original resolution). The resolving part seems quite useless because contrary to EventSource, it might be pretty uncommon to use a relative path to the push service.

This is the way that EventSource works for example (the message handler is overtly associated with the request to a specific service URL).

No, the proposal at https://wiki.mozilla.org/Services/Notifications/Push/API. This was mentioned by Jonas at the Webapps meeting as the way that Mozilla is looking at this API. In that API there are two methods: requestRemotePermission() and checkRemotePermission(); But also separately, I am considering how Web Intents can be used for API service provider discovery, and use.

Is Quota Management API ready for First Public Working Draft?
Hi Kinuko, All - what are people's thoughts on whether or not the Quota Management API spec is ready for First Public Working Draft?

It's been a much wanted feature by developers. Couple of thoughts/questions (sorry for the late feedback, I was on parental leave): 1. My experience with measuring maximum storage quota in existing implementations shows that while some implementations share a common quota across different data stores (e.g. 10 MB for both localStorage and AppCache on iOS last time I looked), not all do. What's the reasoning behind enforcing this (is it easier for implementors? Better for developers?) and is there agreement across implementors that this is the way forward? 2. If the case is that we're going for a binary choice (i.e. persistent vs. temp data stores) why not create specific methods for each rather than pass a constant (or string) as first argument: e.g.: navigator.storageInfo.queryTemporaryUsageAndQuota and navigator.storageInfo.queryPersistentUsageAndQuota That'll avoid having to deal with typos in the first arg, error handling in that case, etc. Best, --tobie

IndexedDB: use of TypeError
So I didn't start working on/implementing indexedDB until after this message went out: http://lists.w3.org/Archives/Public/public-webapps/2012JanMar/0958.html So I haven't had to face the full implications of using TypeError until this week. I'd like to (hopefully not too late) voice my opposition to TypeError for the following scenarios: - invalid value for the 'direction' parameter to open*Cursor (must be 'next', 'prev', 'nextunique', or 'prevunique') - advance(count) where count 1 - open(version) where version 1 The problem here is that these are not easily enforceable by the WebIDL spec, which means implementations have an extra burden of customizing their WebIDL implementation to custom-annotate the IDL extend things like [EnforceRange=Positive] or introducing JS semantics into their otherwise JS-free code. Now this certainly could just be an implementors complaint, but I feel like I can retroactively justify it: The rationale behind the current spec is that these are very similar to a range error where the API has a very narrow range of values, that precede any higher level semantic parameter constraints. But the problem is that they still have some semantic value within IndexedDB - i.e. even though '0' is a valid numeric value to JavaScript, it is invalid because of specific consistencies within the IndexedDB spec. Even though foo is a valid string to JavaScript, strings like next and prev are the only valid strings because they have specific meaning in the context of IndexedDB. So I'd argue that these errors should be indexeddb-specific errors, and/or reused DOMExceptions. What I miss is the NotAllowedError that I believe in an earlier version of the spec, but I could also believe that DOMException's InvalidAccessError could also be used (The object does not support the operation or argument) Alec

Against this rule, I claim that the readability of replies in text-only threads is much worse, unless the replier spends ages paying attention to text formatting by hand which is not acceptable. At least, that was the case the last time I tried. There are several fairly simple reasons supporting Glenn's point (Julian's is simple excessive): 1. Many HTML-producing mail clients still produce very bad HTML, which doesn't translate well to all clients. 2. In the same vein, the WYSIWYG nature often means that people end up producing something that looks good enough, particular with quote towers. Many of the rich-text editors I've seen have really bad usability around quote towers. 3. I've seen a *lot* of abuse of color as a way of distinguishing between quote and reply. This is confusing because, first, it's a second way of doing the same thing, and second, I'm color-blind. Basically, in plain text there's more-or-less only way to do most things. It's really easy to format, especially if you follow a format like Markdown so you don't have to think about things much. I happen to read and write all my messages in plain text, and I can assure you that it does not take ages. Most of the time, all I have to do is trim the whitespace that Gmail inserts at the top, and trim off signatures from the bottom. If I feel like it, I'll take a few seconds to clean up the quote tower too to add or remove blank lines at the correct quote depth as necessary. Responding to your email, for example, took less than 5 seconds of formatting time. ~TJ

At least, that was the case the last time I tried. There are several fairly simple reasons supporting Glenn's point (Julian's is simple excessive): 1. Many HTML-producing mail clients still produce very bad HTML, which doesn't translate well to all clients. 2. In the same vein, the WYSIWYG nature often means that people end up producing something that looks good enough, particular with quote towers. Many of the rich-text editors I've seen have really bad usability around quote towers. 3. I've seen a *lot* of abuse of color as a way of distinguishing between quote and reply. This is confusing because, first, it's a second way of doing the same thing, and second, I'm color-blind. Basically, in plain text there's more-or-less only way to do most things. It's really easy to format, especially if you follow a format like Markdown so you don't have to think about things much. I happen to read and write all my messages in plain text, and I can assure you that it does not take ages. Most of the time, all I have to do is trim the whitespace that Gmail inserts at the top, and trim off signatures from the bottom. If I feel like it, I'll take a few seconds to clean up the quote tower too to add or remove blank lines at the correct quote depth as necessary. Responding to your email, for example, took less than 5 seconds of formatting time. ~TJ And your modified reply causes GMail not to collapse the replied-to text, meaning that when I want to scan through a thread I have to spend a lot more effort finding where the previous email ended and your reply beings. There's a lot of benefits to formatted conversations. I don't understand what benefits people are claiming from plain text that aren't resolved by using an up-to-date MUA.

CfC: Publish FPWD of Web Intents spec; deadline June 12
Dave Raggett (d...@w3.org) made a call [1] on April 10 to publish a first public working draft, and this is a Call for Consensus to do so, using the following document as the basis: dvcs.w3.org/hg/web-intents/raw-file/tip/spec/Overview.html I included public-webapps and public-device-apis on this CfC since Web Intents is a joint-deliverable [2][3] between these two groups. By publishing this FPWD, the group sends a signal to the community to begin reviewing the document. The FPWD reflects where the group is on this spec at the time of publication; it does not necessarily mean there is consensus on the spec's contents. Positive response to this CfC is preferred and encouraged and silence will be considered as agreement with the proposal. The deadline for comments is June 12. Please send all comments to: public-web-inte...@w3.org Thanks, James Hawkins [1] http://lists.w3.org/Archives/Public/public-web-intents/2012Apr/0016.html [2] http://www.w3.org/2012/webapps/charter/ [3] http://www.w3.org/2011/07/DeviceAPICharter
RE: DOM3 Events - additional editing help to move the spec forward

Events' timestamps are also subject to system clock skew and other problems mentioned in High Resolution Time working draft, and providing access to HRT when triggering events will be very helpful to program accurate interactions.

It would be great to discuss this feature in future versions of the drafts mentioned before. I discussed this briefly with Jatinder Mann (who works on the High resolution timing spec--you might know him?). Based on that discussion it sounds like the high-resolution timestamp provides three features: 1. The timestamp is relative to the loaded page (not the Unix epoch) 2. The timestamp can be in microsecond resolution (a best effort-approach) 3. The timestamp is garuanteed to be monotonically increasing. Based on #1, we can't simply replace the current timestamp property on DOM events with a high-resolution time stamp--this would be a change (though perhaps not very impactful) to backward compatibility. Therefore, the only plausible action could be a new property (e.g., highResolutionTimeStamp or similar). However, I wonder what real value this would have. Typically events only fire within the scope of the current window and do not bleed out into other windows (Message and Storage events are notable exceptions)--so new Date() should be self-consistent (coming from the same script engine) even if other script engines are suffering from clock-skew. One issue that is present in IE, is Date objects that get serialized over from Web Workers--they can have a pretty big clock skew pretty quickly, but hypothetically performance.now() can cover those scenarios. Are there other specific use cases that you're finding where the timestamp property doesn't meet your needs?
Re: IndexedDB: use of TypeError
On Tue, May 29, 2012 at 9:49 AM, Alec Flett alecfl...@google.com wrote: So I didn't start working on/implementing indexedDB until after this message went out: http://lists.w3.org/Archives/Public/public-webapps/2012JanMar/0958.html So I haven't had to face the full implications of using TypeError until this week. I'd like to (hopefully not too late) voice my opposition to TypeError for the following scenarios: invalid value for the 'direction' parameter to open*Cursor (must be 'next', 'prev', 'nextunique', or 'prevunique') advance(count) where count 1 open(version) where version 1 The problem here is that these are not easily enforceable by the WebIDL spec, which means implementations have an extra burden of customizing their WebIDL implementation to custom-annotate the IDL extend things like [EnforceRange=Positive] or introducing JS semantics into their otherwise JS-free code. Now this certainly could just be an implementors complaint, but I feel like I can retroactively justify it: The rationale behind the current spec is that these are very similar to a range error where the API has a very narrow range of values, that precede any higher level semantic parameter constraints. But the problem is that they still have some semantic value within IndexedDB - i.e. even though '0' is a valid numeric value to JavaScript, it is invalid because of specific consistencies within the IndexedDB spec. Even though foo is a valid string to JavaScript, strings like next and prev are the only valid strings because they have specific meaning in the context of IndexedDB. So I'd argue that these errors should be indexeddb-specific errors, and/or reused DOMExceptions. What I miss is the NotAllowedError that I believe in an earlier version of the spec, but I could also believe that DOMException's InvalidAccessError could also be used (The object does not support the operation or argument) The open*Cursor exception should be enforcable using WebIDL by using an enum. The only reason we don't have it that way in the spec is because ReSpec doesn't support that. For the other exception, I would say that it seems weird if -1 threw one error and 0 threw another one, so I'd like to stick to the current spec. There is of course also the fact that the requested change doesn't obviously make it better for web developers and that it's late in the game to make this change. What we've done in Gecko is to create a special C++ error code which turn into a TypeError by the JS-glue layer. That way we don't have to add new WebIDL annotations but we also don't have to introduce JS-isms into the C++ code. I suspect more specs will end up throwing TypeError so that solution seems good for future proofing. / Jonas

Are there other specific use cases that you're finding where the timestamp property doesn't meet your needs? The main value is that it makes it much easier to synchronize the event with various animations going on. The requestAnimationFrame API uses high resolution timers relative to the page load time, as does the performance.now() function. By putting time stamps of the same unit on events, it's much easier to do things like start animations when an event occurred, but do all rendering in requestAnimationFrame. I.e. it makes it easier to account for moving the animated item between the event occurs and when the rendering happens. Likewise it makes it easier to do things like hit detection to figure out where various objects on the screen were when an event occurs, accounting for partial movement between two rendered frames. / Jonas
