French version

After four months without news, I'll try to be more regular. Let's hope my new organisation will help.

Changes of the week

Everything mentioned below should work with the latest nightly available at the moment (42662).

6 parallel connections (42457, 42559)

With this commit, WebKit can now use 6 parallel connections per domain, previously 4. The number of parallel connections is important to download as fast as possible the resources of a web page. WebKit is now behaving like latest versions of IE, Firefox or Chrome. Opera uses 8 connections per domain. To test this, you'll have to wait for a future version of the CFNetwork library.

function.displayName (42478)

You can create anonymous function in JavaScript. They are very useful but the drawback is they also appear anonymous in the profiler. This make the interpretation of the results pretty hard. Now, you can give a name to those functions and it will be used in the profiler.

Yarr! (42481)

Yarr! (Yet Another Regex Runtime) is, as it suggests, a new Regex Runtime. It is disabled by default for some reasons like being incomplete at the moment but said to be faster than the old one. Hoperfully, we'll have more news when he'll be live.

XMLHttpRequest withCredentials (42483)

This is a new feature from the XMLHttpRequest Level 2 spec. With the withCredentials attribute, you can define whether or not you wanna send the cookies and HTTP authentication data when using a cross domain XHR. Like the number of parallel connections, we need a new version of CFNetwork to test this.

Array.reduce and Array.reduceRight (42563, 42570)

These are two new methods define by ECMAScript 5. You are invited to read the documentation on the Mozilla developer center.

SQL is read only with private browsing (42616)

When using the private browsing mode (aka porn mode), the web database is no longer writeable. Inserts, updates, deletes are no longer available. This way, the website can't record stuff while in a private session.

Implementation of the played attribute (42619)

The new video element has a played attribute which give info about what part of the video has been played. You got access to a TimeRanges object.

This is everything for this week. Of course, this is just a selection I've made. If you've noticed any other interesting changes, please let me know. Same thing if I got something wrong.

French version

Apologizes for the chaotic rhythm of publication. So here is a raw version.

Changes of the week

Everything mentioned below should work with the latest nightly available at the moment (38100).

Multiline Inputs (35739)

Before this commit, WebKit was only sending the first line of an input field. Now, a multiline text (entered with copy and paste) will keep all the text. The carriage return will be replaced by spaces. This matches other browsers behavior.

Computed styles tab collapsed (37523)

After the post on the redesigned Web Inspector, many people were asking why styles can't be edited. In fact, they were trying to edit the computed styles. As the name explains, it represents the final styles after being calculated by the browser and therefore, they are not editable. To avoid this confusion and keep an easy access to this data, this tab is now collapsed by default.

Debug without reloading the page (37622)

Wanna debug some Javascript ? You just have to enable the debugger and there you go. No reloading involved.

Time and size per resource

In order to ease the interpretation of the waterfall in the Resources panel, the time and size for each resources were added. You just have to hover the resource to get the different times (waiting and loading times) or the size of the resource.

On demand profiler (37730, 37933)

Before these commits, the profiler was always enable when the Safari's Developer menu was enabled. This affects performance, even when you weren't running a profile. Now, the profiler is disabled by default. A new activation screen is therefore necessary. A similar screen was added for the profiler too.

Geolocation API (37854)

A lot of applications could benefit from knowing the user position and offer local services. So an API is under development at the W3C : Geolocation API. There is a clear usecase with the iPhone for example. This functionality can't be tested in the nightlies at the moment.

Multi-file upload (37863)

HTML5 introduces the multiple attribute on file inputs. This allows uploading multiple files at a time. Combined with XMLHttpRequest version 2, this allows uploading files with a progression bar without external plugins.

Mozilla cursors (37902)

Two new values were added to customise cursors : -webkit-grab and -webkit-grabbing. They were already used in Mozilla. Demo of all supported cursors

Changing the accesskey shortcut (38211)

Originally, the accesskey shortcut was Ctrl. This caused collisions with the Emacs style shortcuts in Mac OS. The shorcut was changed to Ctrl+Opt. But this caused new problems with VoiceOver. So the intermediate solution is now : Ctrl+Opt without VoiceOver and Ctrl with VoiceOver.

Julien Chaffraix and I were at Paris Web 2008. Among many good moments, they were a nice browser panel with a represent of the four big engines.

This is everything for this week. Of course, this is just a selection I've made. If you've noticed any other interesting changes, please let me know. Same thing if I got something wrong.

French version

One month without news is bad. So we resume with only two weeks.

Changes of the week

Everything mentioned below should work with the latest nightly available at the moment (37469).

Styling placeholder (37123, 37217)

WebKit supports a placeholder attribute on input elements. This attribute allows you to display a tooltip in the field when the user hasn't enter any content. By default, this tooltip is printed in light gray. Now, we can play with his style using the -webkit-input-placeholder pseudo-element. See the example.

Debugging before onload fires (37313)

Before this fix, it was impossible to debug a part of code running before the resource finished its loading. It wasn't really handy for a tool like the Web Inspector. Fixed !

Origin header for POST requests (37317)

Beginning of implementation for the Access Control for Cross-Site Requests specification. An Origin header, which only contains the domain of the originating page, is added. This allows application to check if the request comes from an authorized domain. Unlike the Referer header, this one doesn't reveal the complete path of the originating page.

Exact line search (37389)

Like Firebug, it's now possible to search for a particular line in the Resources panel. We can use two syntaxes : #123 or line:123. We can add a keyword to only match lines with this keyword.

Fixing SunSpider (37389)

As David Mandelin mentioned on his blog, the regexp-dna test on SunSpider was incorrect. An option only supported in Gecko was in the test and so, this engine was disadvantaged. Eveyrthing is fine now, all the engines do the same test.

News of the week

While I wasn't giving news, three new posts were added to the Surfin' Safari blog:

• Introducing Squirrelfish Extreme, the latest evolution of the JavaScript engine.
• Full pass of Acid3, the last condition (smooth animation) is now ok.
• Web Inspector redesign, a summary of all the evolutions for the last nine months.

This is everything for this week. Of course, this is just a selection I've made. If you've noticed any other interesting changes, please let me know. Same thing if I got something wrong.

Changes of the week

Everything mentioned below should work with the latest nightly available at the moment (35806).

CSS Animations implementation (35666)

I announced this implementation too early last week. Comparing to the two specs, associated events were missing.

Compatibility with Firebug's API (35676, 35786, 35787)

New commands are available in the console. $, $$, $x, keys, values, profile/profileEnd, clear. You can find these functions descriptions in Firebug's documentation And don't forget the addition of console.dir to list all properties of an object.

SVG tests (35675, 35679, 35680, 35682, 35683, 35695, 35700)

I'm not familiar with SVG but something like 80 tests were added to ensure the right behaviour of the engine. Especially, the elements line, radialGradient, image, marker, mask, cursor, pattern and rect are concerned. Some fixes were made in consequence.

Resizable and closable inspector in docked mode (35719, 35720, 35722)

When the inspector is inside a page, it is now possible to resize and close it. I waited a long time for this. This docked mode is now the default. And to finish with this, the inspector will remember in which mode you've let it.

Loader enhancements (35799, 35801)

In order to always get better performances, some tweaks were made :

• Stylesheets get highest priority since the engine won't render before having downloaded every stylesheets.
• For each new host, the connection is established as soon as possible in order to reduce the effect of the latency due to it.
• When the document and all stylesheets are parsed, there's no need to maintain a queue, we can download all documents, whatever priority they have.
• To avoid delaying the initial rendering, resources in <body> are not downloaded if there's no render. This improves by 25%, or 5 seconds, the initial rendering for CNN with a bandwith limited to 300kb/s, interesting for mobile devices.

This is everything for this week. Of course, this is just a selection I've made. If you've noticed any other interesting changes, please let me know. Same thing if I got something wrong.

French version

I've been following the WebKit project for 4 months now and I thought it would be interesting to extract cool news of the week here. This is the first post in this series and I hope it will be interesting and live long.

I'm French so my tailor is rich but my English is poor. Please correct me if you find mistakes.

Changes of the week

Everything mentioned below should work with the latest nightly available at the moment (35531).

CSS parser enhancements (35403)

It's always good to improve standards compliance. The menu:

• don't fail when closing braces are not found for a declaration at the end of the file;
• don't accept "!important fail" as valid;
• keep accepting @import when it comes after invalid @ rules;
• don't drop the whole @media block when there's an error before the closing brace;
• some other minor css parsing revisions.

Support for CSS variable declaration blocks (35414)

The CSS WG is working (among other stuff) on CSS variables. To support this effort and try to find the best syntax, there are some tries in WebKit.

So this week, we have support for CSS variable declaration blocks. See the example in a test to see how it works.

Of course, these are experiments and do not represent the final syntax. There are other experimentations going on, like the use of the var keyword.

Support for console.group (35421)

Let's start by saying the Web Inspector (WebKit's equivalent to Firebug basically) is being refreshed. It has almost nothing to do with the one in Safari 3.1. Try it!

One of the novelty is to support the same Console API as Firebug to help web developers work.

This week, WebKit now supports console.group and console.groupEnd. I must point out this work was done by Keishi Hattori, one of the students participating in the Webkit GSoC .

Support for XMLHttpRequestUpload (35435)

Again, a work in progress specification and a testing implementation. The implementation has even more details than the latest spec I could find.

The idea ? Add events to allow better knowledge about the status of the XHR request. This could allow upload forms with progress bars.

The example shows the new available events and properties.

Ability to disable individual CSS properties (35514)

Also in the refresh project of the inspector. A useful functionality to analyse a web page design, try new things, etc.

News of the week

Ariya Hidayat had some fun adding a live tab previews in Arora (a browser based on QtWebKit).

This is everything for this week. Of course, this is just a selection I've made. If you've noticed any other interesting changes, please let me know. Same thing if I got something wrong.
