Volunteers Wanted: Trac Enhancements

Posted on by

The jQuery and jQuery UI teams use Trac to do their bug reporting and tracking. The jQuery Core bug tracker could really use a Trac expert to migrate us to Trac 1.0 and fix a few nagging issues we’ve been having. If you’re an expert Trac-meister, or just someone with good Trac setup/configuration experience who’s up to the challenge, we’d love to talk with you! Send a message to dave(at)jquery.com and we’ll be in touch.

Since some of you will inevitably ask: GitHub’s integration between issues and commits is wonderful, but it’s not anywhere near as powerful as Trac when it comes to searching and reporting. In addition, our projects have more than seven years of history comprising thousands of bug reports with important data in them. That’s a non-trivial amount of data to import into GitHub issues and groom to be useful once it’s imported. We feel that staying with Trac is the lowest-effort way for us to give us the bug tracking abilities we need.

Don’t Use jquery-latest.js

Posted on by

Earlier this week the jQuery CDN had an issue that made the jquery-latest.js and jquery-latest.min.js files unavailable for a few hours in some geographical areas. (This wasn’t a problem with the CDN itself, but with the repository that provides files for the CDN.) While we always hope to have 100% uptime, this particular outage emphasized the number of production sites following the antipattern of using this file. So let’s be clear: Don’t use jquery-latest.js on a production site.

We know that jquery-latest.js is abused because of the CDN statistics showing it’s the most popular file. That wouldn’t be the case if it was only being used by developers to make a local copy. The jquery-latest.js and jquery-latest.min.js files were meant to provide a simple way to download the latest released version of jQuery core. Instead, some developers include this version directly in their production sites, exposing users to the risk of a broken site each time a new version of jQuery is released. The team tries to minimize those risks, of course, but the jQuery ecosystem is so large that we can’t possibly check it all before making a new release.

To mitigate the risk of “breaking the web”, the jQuery team decided back in 2013 that jquery-latest.js could not be upgraded to the 2.0 branch even though that is technically the latest version. There would just be too many sites that would mysteriously stop working with older versions of Internet Explorer, and many of those sites may not be maintained today.

As jQuery adoption has continued to grow, even that safeguard seems insufficient to protect against careless use of http://code.jquery.com/jquery-latest.js. So we have decided to stop updating this file, as well as the minified copy, keeping both files at version 1.11.1 forever. The latest released version is always available through either the jQuery core download page or the CDN home page. Developers can download the latest version from one of those pages or reference it in a script tag directly from the jQuery CDN by version number.

The Google CDN team has joined us in this effort to prevent inadvertent web breakage and no longer updates the file at http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js. That file will stay locked at version 1.11.1 as well. However, note that this file currently has a very short cache time, which means you’re losing the performance benefit of of a long cache time that the CDN provides when you request a full version like 1.11.1 instead.

So please spread the word! If you see a site directly using the jQuery CDN’s jquery-latest.js or the Google CDN equivalent in their script tags, let them know they should change to a specific version. If you need the latest version, get it from the download page or our CDN page. For both the jQuery and Google CDNs, always provide a full version number when referencing files in a <script> tag. Thanks!

jQuery 1.11.1 and 2.1.1 Released

Posted on by

Ah, the air is sweet with the scent of spring and new jQuery 1.11.1 and 2.1.1 are in bloom. These are minor patch releases and shouldn’t pose any major compatibility issues. Throw a Cinco de Mayo party and have your friends come over to test. If you dig up a problem, let us know at bugs.jquery.com, and be sure to provide a simple test case using jsfiddle.net or jsbin.com to demonstrate the problem.

You can include these files directly from the jQuery CDN if you like, or copy them to your own local server. The 1.x branch includes support for IE 6/7/8 and the 2.x branch does not.

http://code.jquery.com/jquery-1.11.1.js
http://code.jquery.com/jquery-2.1.1.js

The Google and Microsoft CDNs will be getting their copies today just like you did, so please give them a few days to post the files and don’t be impatient. If you’re anxious to get a quick start, just use the files on our CDN until they have a chance to post.

Minified files (for production use) and map files (for debugging) are also available. If you want to use the map file for debugging the minified code, copy the minified file and add a //# sourceMappingURL comment to the end of the file.
http://code.jquery.com/jquery-1.11.1.min.js
http://code.jquery.com/jquery-1.11.1.min.map
http://code.jquery.com/jquery-2.1.1.min.js
http://code.jquery.com/jquery-2.1.1.min.map

Many thanks to all of you who participated in this release by testing, reporting bugs, or submitting patches, including Benjy Cui, Christian Kosmowski, Jason Frank, Julian Aubourg, Jens Simon, John Hoven, John Madhavan-Reese, Jonathan Sampson, Jörn Zaefferer, Leo Balter, Louis-Rémi Babé, Michał Gołębiowski, Oleg Gaidarenko, Philip Jägenstedt, R.G.

jQuery Chicago Pebble Giveaway and Filing Extension

Posted on by
jQuery Conference Chicago logo

As we announced at the end of jQuery San Diego in February, we’re excited that the next stop for #jqcon is Chicago! In case you missed the news, we’ll be setting up shop in the City That Never Sleeps Isn’t Windy on September 12th & 13th, 2014. We’re partnering again with Bocoup to make it a four-day affair, bringing you Roost on September 11th & 12th.

Speaker Filing Extension

While we can’t do anything about today’s deadline for those of us in the US to file our tax returns, we can offer our own form of amnesty: a two-week-plus extension of our Call for Speakers until the end of April! If you got swamped in receipts – or anything else – and thought you’d missed your chance to submit, breathe a sigh of relief, and if you didn’t know the call was even open, this should hopefully provide you enough time to come up with a solid talk proposal. (And if you already have submitted, thanks!)

We’re experimenting a bit with our time slot construction in Chicago, so if you have a talk that you feel needs to go deep into technical material and run for 45 minutes or an hour, or want to lead a more hands-on-workshop type of session for even longer, we’re eager to hear about it and encourage you to to get in touch with questions about your ideas at [email protected] or on the #jquery-content channel on Freenode.

Join Us

Our early bird tickets have been going fast and will likely be gone before our original early-bird cutoff of May 31st, so if you’re aiming to keep another 50 bucks in your deep-dish pizza budget, you’ll want to act sooner than later!

The conference will be right downtown at the Sheraton Chicago Hotel & Towers, and we’re able to offer attendees of both jQuery Chicago and Roost a discounted rate if you register as part of our room block.

Join Us…Together!

We’ve always held that jQuery is better with friends, and if you’ve got colleagues you want to attend with or send to the conference, we have group packages available that include sponsorships and discounts. Get in touch with us for a prospectus and to figure out how to get your team to Chicago!

A “Rocky” Start

Pebble logo If the prospect of jQuery’s first foray into the Old Northwest wasn’t exciting enough, we’re psyched to inform you that we’ll be giving away classic Pebble devices throughout ticket sales. We’ll take a random draw of people who’ve bought tickets each month and select 2-3 folks who’ll receive a Pebble from us (and the kind folks at Pebble who’ve donated the devices) at the conference in September. The sooner you buy, the better your odds, so what are you waiting for? This post is over anyway!

Browser Support in jQuery 1.12 and Beyond

Posted on by

With Microsoft ending Windows XP support this month, we’re giving the jQuery community some long-lead-time notice on changes to browser support.

First of all, don’t panic! Nothing is really changing with respect to the browsers that can run jQuery for at least six more months. Our goal is to let everyone in the web development community know what the jQuery team intends to do over the next year, so that you can plan accordingly.

What’s Changing?

There are no firm dates, but we plan on releasing jQuery core versions 1.12 and 2.2 this year. jQuery 1.13/2.3 will be released some time in 2015.

jQuery 1.12: This will be the last release to support Internet Explorer 6 and 7. As of today, no feature requests or bug fixes will be landed for them. Only serious regressions for these browsers will be fixed in patch releases (e.g., 1.12.1). jQuery 1.13 will support IE8 as its minimum browser.

Both jQuery 1.12 and 2.2: These will be the last releases to support Opera 12.1x and Safari 5.1. As of today, no feature requests or bug fixes will be landed for them. Only serious regressions for these browsers will be fixed in patch releases (e.g., 1.12.1 or 2.2.1).

Both jQuery 1.13 and 2.3: We will remove patches and workarounds that are specific to API conformance for the browsers we no longer support, in order to simplify the code base.

What you need to do: If your projects use a package manager that pulls in the latest release of jQuery, keep in mind that the 1.12-to-1.13 or 2.2-to-2.3 upgrade will reduce browser coverage. You may want to stay on 1.12 or lower if support for older browsers is required. See the instructions of your package manager for details on how to do that.

The Meaning of “Support”

Defining what “support” means is trickier than you might think. Under the premise that “untested code is broken code,” the jQuery core team prefers to say we fully support a browser if the project regularly runs unit tests against that browser. The unit tests ensure that every API returns a consistent set of results in all browsers.

Even when we support a browser, there can be bugs we can’t reasonably fix. For example, Internet Explorer 6 through 11 fire focus and blur events asynchronously and the code required to make them appear synchronous would be significant. Safari on iOS doesn’t support the onbeforeunload event which is pretty much impossible to shim. Until last month, Firefox didn’t respect overflow: hidden on a fieldset element. We try to work with browser vendors to get these bugs fixed.

On browsers that we don’t officially support, we still work hard to eliminate “killer bugs” such as script errors during initialization that make the page totally unusable. If you want to see the lengths to which we go to deal with obscure problems, look at this browser-crashing Android 2.3 bug on Japanese phones which was extremely intermittent and hard to diagnose. With the help of several users we were able to track down and work around the problem.

It comes down to this: We can only ensure high-quality continuing support for the browsers and environments we constantly unit-test. However, we will try to provide some reasonable level of support to browsers in any popular environment. The highest priority will be on ensuring the browser doesn’t throw errors. Low priority will be put on ensuring that old or rare browsers produce the exact same API results as modern browsers.

Who Uses Old Browsers Now?

When looking at browser stats, don’t look at where they are today. Think about where they will be in 2015. All told, we think all these browsers will be in the small single digits of market share by then. If numbers from StatCounter can be believed, these browsers are already there and will be even less prevalent when jQuery finally drops support.

Ultimately these whole-Internet stats don’t matter though. What really matters is whether the visitors to your site or users of your web application are running a particular browser. That is something that only you can answer. The decision to upgrade to a new jQuery version is always in your hands as a developer.

The Myth of Browser Consistency

Today and long into the future, jQuery will still contain dozens of browser-specific fixes to normalize behavior. At this point, the most problematic and troublesome browser for jQuery 2.x is the one in Android 2.3. That version is still a significant 20 percent of the Android installed base, and still being shipped in new mobile products. Several JavaScript features like element.classList are not supported there, and it’s one of the last browsers to still require -webkit-prefixing for standardized CSS properties.

jQuery projects are all about making your development life easier, so we’ll continue to support the fixes that are needed to smooth out inconsistencies on popular browsers. As the market share of specific browsers dwindles to zero, we’ll take the opportunity to remove their patches and de-support them in order to streamline our code bases. That makes all jQuery pages a little bit faster.

jQuery 1.11.1 Beta 1 and 2.1.1 Beta 1 Released

Posted on by

It’s been a couple of months since our last releases escaped the grip of endless winter, so we thought it would be good to thaw out a beta that collects up the bugs that have been reported and fixed recently. Most of these bugs are mild as severity and frequency go, but that’s easier to say if you’re not impacted!

As with all our beta releases, we make them available so you can test against them and let us know if they fix the bugs without introducing new bugs, surprising behaviors, or regressions. Please help us out by dropping these files into your projects and pages for a quick spin. If you discover any undesirable changes, let us know at bugs.jquery.com.

The beta files are located on the jQuery CDN, you can include them directly from the CDN if you like (but don’t use them in production!). As always, the 1.x branch includes support for IE 6/7/8 and the 2.x branch does not:

Supporting the Cause, Improving the Web

Posted on by

To help the jQuery Foundation accomplish its mission to improve the open web and make it accessible to everyone, we established a membership program where organizations and individuals could join the foundation to help us support our goals. In return, members are recognized both on our websites and at conferences. Since that time, a number of companies, large and small, as well as individuals, have stepped up to support the foundation and continued success of the jQuery projects. A full listing of our members is available on the member page on jquery.org.

Corporate Memberships

Corporate memberships are available in several levels based on support, ranging from Bronze to Platinum. Beyond those levels is our top level membership called our Founding members. Currently, WordPress is our single Founding member at this time and they are a huge part of the jQuery Foundation mission and we would like to say a special thank you to them. We would not be here if it wasn’t for the support of WordPress and our many corporate members at every level.

So what does a member get in return for their support of the Foundation? Depending on the level of support, there are a number of ways we recognize and thank our members. Every member is recognized on the member page. As you progress up through the different levels of membership, more benefits such as conference recognition, free and reduced price conference sponsorship packages, invitations to team meetings to discuss the development and direction of the jQuery projects, and even the ability to host jQuery licensed events of your own. For more information about the corporate membership program, e-mail us at [email protected].

I’m not a Corporation, how can I help?

We’re glad you asked. The jQuery Foundation also has an individual membership program where people can donate smaller amounts to help support the Foundation and in return, we send out some cool jQuery branded gear. When the program started, we offered three levels of membership for individuals. That just got too complicated for both the members joining as well as the folks managing the payment and gift fulfillment. There is now only one level of individual membership at the $400 per year level. If you think about it, that’s really only a little more than $1/day to help keep the jQuery Foundation running. You can see all of our individual members listed on the member page. As new members are added, they will be listed as Heroes until the transition from a 3-tier to 1-tier program is complete and everyone has merged into a single list of Individual Members. If all of this has got you itching to become part of the next wave of individual members, head on over to https://jquery.org/join/ and join our ranks.

Membership may not be an option for everyone, but there are still ways you can support the Foundation’s work. The first way is through donations. The jQuery Foundation accepts donations, both large and small, through PayPal. If that’s an option that interests you, check out our donate page. Another way to help the foundation is by grabbing yourself a nice shirt or some stickers over at DevSwag. We have partnered with DevSwag, as many other open source projects have, to license the sale of official jQuery branded clothing and other items and a portion of the proceeds from those items are donated to the jQuery Foundation.

No matter if you’re a company or an individual, we hope you’ll take the time to consider supporting the jQuery Foundation to keep us working toward making the web accessible to everyone.

One Last Thing …

We thought we would let you know one more time about the upcoming jQuery Conference in San Diego. The conference is February 12-13 and is preceded by Bocoup’s 2 day training conference Roost on February 10-11. Don’t forget to take $50 off your ticket to one or both of these events using discount code jqblog50 at checkout!

Hosting and Configuring the jQuery Servers

Posted on by

The other day, we posted about our new content workflow, but we didn’t get into how all that content is actually served. Believe it or not, jQuery doesn’t just run on jQuery.

The servers

The servers themselves are hosted at Media Temple. We have been using their VPS services for many years to host all the things we need to host, of which there are a surprising number. We use over a dozen different servers (of various sizes) hosting everything in the jQuery network including many different web sites, applications and services vital to the community and development team. The reliability of the Media Temple VPS services and network for our infrastructure has been fantastic.

The setup

We couldn’t manage all of the servers without Puppet. Puppet is a configuration management tool that makes it really easy to express server configuration in a simple scripting language. Tasks like adding a domain to the Nginx configuration can be annoying, and hard to track changes using conventional methods. Using Puppet lets us store all the server configuration needed in a git repository, and deploy new machines very easily.

Another product that really shines in our setup is Nginx. Nginx is an open source web server focused on delivering the best performance possible. On our busiest Media Temple Dedicated Virtual server around peak times, Nginx handles about 300 HTTP requests per second, of which about 30 are serving pages from WordPress via php-fpm. Nginx’s built in fastcgi_cache handles a lot of that load, and more like 2 or 3 requests per second actually make it to PHP.

Thanks for the support!

Keeping a network of servers running to support a community as large as jQuery’s is a big job. To help ensure everything runs smoothly, we rely on jQuery Infrastructure team members Adam Ulvi and Ryan Neufeld, and for server and network-related issues we count on prompt and helpful support from the Media Temple team.

To celebrate their 7 years of serving the jQuery community, Media Temple is extending a special offer on their VPS and Grid Hosting. For the next 5 days, get 50% off an annual purchase of a Grid or VPS (up to level 3) service with the code LovejQuery50.

Speaking of support, if you need any support with jQuery, or the related web sites and services, check out one of our IRC channels on freenode.

jQuery 1.11 and 2.1 Released

Posted on by

Here in the eastern part of the United States, we’re huddling in subzero temperatures and dealing with the aftermath of a snowstorm. Still, there’s nothing to brighten our moods like the pristine beauty of a freshly fallen release–no, make that TWO releases. jQuery 1.11.0 and 2.1.0 are ready to keep you warm on these dark winter nights.

You can get the files off our CDN as always, and either use them directly or download them to your own server. Our download page has all the files and information you need, including pointers to the other CDNs that carry the files. Just give those folks a few days to update!

For those of you not following along for a while, both the 1.x and 2.x branches of jQuery support all recent modern browsers and have the same API. The 1.x branch, this time 1.11.0, adds support for the older versions of Internet Explorer (IE6, 7, and 8). The 2.x branch, today played by 2.1.0, adds support for non-traditional web environments like node.js and browser plugins for Chrome and Firefox.

jQuery went through a major house-cleaning with the 1.9 release that removed some features. If you haven’t yet moved from an earlier version, see the jQuery 1.9 Upgrade Guide and let the jQuery Migrate plugin do all the heavy lifting for you.

What’s New?

You may be wondering what great new things await you in these releases. Perhaps you’re fearing that they hold a bunch of breaking changes. You just know the project lead will suggest updating things right now. There goes your whole damn week and that trip to Florida. Well fear not! We’ve fixed quite a few bugs, but the other features and changes are mainly organizational ones that don’t affect the behavior of APIs. Your code shouldn’t break, it should just run a little faster. Here are the highlights:

Fewer forced layouts: In this release we declared war on places where we might inadvertently force the browser to do a time-consuming layout. We found a few and eliminated one in particular that could occur when changing class names. This can result in a big performance boost for some pages.

Granular custom builds: Our modularity is now defined by AMD, and it is easier to build small subsets of the library when space is at a premium. If you want to know more, we’ve hidden the details in the README file where nobody ever looks.

Lower startup overhead: The new modularity and avoidance of forced layouts led us to refactor our feature detects so that they run the first time they’re needed. If you never call the API needing that feature detect, you never run that code. Previously we ran all feature detects when the page loaded, that led to delays that were generally small, but added up–especially on mobile platforms.

Published on npm: Our releases will now be published on npm so that you can use them with node or browserify. Both the 1.x and 2.x branches are available on npm, but remember that only the 2.x branch is supported to run in node.

Published on Bower: We’re now using Bower for our internal dependency management including Sizzle, so you’ll see jQuery releases on Bower as soon as they’re available.

Some people have asked about supporting other package managers inside the jQuery library, but we’ve decided to only support the two that we use internally at the moment. There are more than a dozen package/dependency managers, it would be handy if they all could agree on a single format for projects to publish information. We don’t want the package manager’s overhead to be pushed off to individual projects like jQuery.

Although the glamor always seems to be in the new stuff, we don’t like to ignore the bugs and inconveniences that people have run across while using the last version. We worked hard to knock down our bug list and tackled quite a few of them. We even fixed a bug that only occurs in IE6, better late than never!

Sourcemap changes

This release does not contain the sourcemap comment in the minified file. Sourcemaps have proven to be a very problematic and puzzling thing to developers, spawning hundreds of confused developers on forums like StackOverflow and causing some to think jQuery itself was broken.

We’ll still be generating and distributing sourcemaps, but you will need to add the appropriate sourcemap comment at the end of the minified file if the browser does not support manually associating map files (currently, none do). If you generate your own jQuery file using the custom build process, the sourcemap comment will be present in the minified file and the map is generated; you can either leave it in and use sourcemaps or edit it out and ignore the map file entirely.

We hope to bring back and improve sourcemap support in the future, but at the moment neither the design nor the implementation seem suited for situations like jQuery’s, where there are widely distributed files on CDNs. We’d like sourcemaps (and browsers supporting them) to gracefully handle situations like file renaming or missing files. See our bug ticket for more information.

Acknowledgements

This release would not have happened without the hard work of many people. Thanks to everyone who reported bugs, tried out the prerelease files, or provided constructive criticism.
