Alex Vincent: Introducing a WebGL-DOM Visualization Tool

Mozilla planet - vr, 24/07/2015 - 09:15


Home page:

tl;dr:  I have a new way of visualizing DOM trees in WebGL, and I’m looking for volunteers to improve the basic tool, especially on the WebGL side with three.js.

I’ve run into some trouble with an experimental Document Object Model.  Specifically, I’m trying to visualize it, but I’m dealing with multiple dimensions:

  • The parent-child node relationships
  • Sibling nodes
  • Attributes of DOM Element nodes
  • Atomic change sets
  • and at least two models of “shadow content”.

About four to six weeks ago, I realized I needed a tool to not only debug the DOM I’m trying to build, but to simulate new ideas that I haven’t yet implemented.  So I started building a WebGL-based visualization tool.

The tool currently has two main tasks:

  1. Transforming a XML document into a specific JSON format
  2. Generating a tree diagram in WebGL from JSON documents in the specified format

Most importantly, hand-editing this JSON should allow me to show ideas that currently cannot be done in the standard DOM.  The “WebGL Inspector sample” link from the home page shows this:  it takes only JSON as input and renders the tree.

It is very primitive right now, a mere starting point.  I’m posting this now, hoping to find a volunteer who’s more familiar with WebGL / three.js than I am to improve on the rendering parts.  The image is static:  there’s no zoom, pan, or rotation support whatsoever.  I really would like some help there.

Also, it doesn’t work in Google Chrome, but that’s because I had to specify type=”application/javascript;version=1.8” to make it work in Mozilla Firefox 39+.  (I like ECMAScript 6th edition and strict mode, thank you very much.  I just wish it worked without versioning.  I understand that’s Coming Soon.)

There is some click support:  clicking on a sphere should give details about the corresponding DOM Node, including the nodeName and nodeType.

If anyone out there likes the 3-D visualization idea and wants to reimplement it in the Firefox Developer Tools, be my guest.  Though the Tilt add-on for Firefox is more practical right now.

Nick Desaulniers: Additional C/C++ Tooling

Mozilla planet - vr, 24/07/2015 - 06:10

21st Century C by Ben Klemens was a great read. It had a section with an intro to autotools, git, and gdb. There are a few other useful tools that came to mind that I’ve used when working with C and C++ codebases. These tools are a great way to start contributing to Open Source C & C++ codebases; running these tools on the code or adding them to the codebases. A lot of these favor command line, open source utilities. See how many you are familiar with!

Build Tools CMake

The first tool I’d like to take a look at is CMake. CMake is yet another build tool; I realize how contentious it is to even discuss one of the many. From my experience working with Emscripten, we recommend the use of CMake for people writing portable C/C++ programs. CMake is able to emit Makefiles for unixes, project files for Xcode on OSX, and project files for Visual Studio on Windows. There are also a few other “generators” that you can use.

I’ve been really impressed with CMake’s modules for finding dependencies and another for fetching and building external dependencies. I think C++ needs a package manager badly, and I think CMake would be a solid foundation for one.

The syntax isn’t the greatest, but when I wanted to try to build one of my C++ projects on Windows which I know nothing about developing on, I was able to install CMake and Visual Studio and get my project building. If you can build your code on one platform, it will usually build on the others.

If you’re not worried about writing cross platform C/C++, maybe CMake is not worth the effort, but I find it useful. I wrestle with the syntax sometimes, but documentation is not bad and it’s something you deal with early on in the development of a project and hopefully never have to touch again (how I wish that were true).

Code Formatters ClangFormat

Another contentious point of concern amongst developers is code style. Big companies with lots of C++ code have documents explaining their stylistic choices. Don’t waste another hour of your life arguing about something that really doesn’t matter. ClangFormat will help you codify your style and format your code for you to match the style. Simply write the code however you want, and run the formatter on it before commiting it.

It can also emit a .clang-format file that you can commit and clang-format will automatically look for that file and use the rules codified there.

Linters Flint / Flint++

Flint is a C++ linter in use at Facebook. Since it moved from being implemented in C++ to D, I’ve had issues building it. I’ve had better luck with a fork that’s pure C++ without any of the third party dependencies Flint originally had, called Flint++. While not quite full-on static analyzers, both can be used for finding potential issues in your code ahead of time. Linters can look at individual files in isolation; you don’t have to wait for long recompiles like you would with a static analyzer.

Static Analyzers Scan-build

Scan-build is a static analyzer for C and C++ code. You build your code “through” it, then use the sibling tool scan-view to see the results. Scan-view will emit and open an html file that shows a list of the errors it detected. It will insert hyperlinks into the resulting document that step you through how certain conditions could lead to a null pointer dereference, for example. You can also save and share those html files with others in the project. Static analyzers will help you catch bugs at compile time before you run the code.

Runtime Sanitizers ASan and UBSan

Clang’s Address (ASan) and Undefined Behavior (UBSan) sanitizers are simply compiler flags that can be used to detect errors at runtime. ASan and UBSan two of the more popular tools, but there are actually a ton and more being implemented. See the list here. These sanitizers will catch bugs at runtime, so you’ll have to run the code to notice any violations, at variable runtime performance costs per sanitizer. ASan and TSan (Thread Sanitizer) made it into gcc4.8 and UBSan is in gcc4.9.

Header Analysis Include What You Use

Include What You Use (IWYU) helps you find unused or unnecessary #include preprocessor directives. It should be obvious how this can help improve compile times. IWYU can also help cut down on recompiles by recommending forward declarations under certain conditions. I look forward to the C++ module proposal being adopted, but until then this tool can help you spot cruft that can be removed.

Rapid Recompiles ccache

ccache greatly improves recompile times by caching the results of parts of the compilation process. I use when building Firefox, and it saves a great deal of time.


distcc is a distributed build system. Some folks at Mozilla speed up their Firefox builds with it.

Memory Leak Detectors Valgrind

Valgrind has a suite of tools, my favorite being memcheck for finding memory leaks. Unfortunately, it doesn’t seem to work on OSX since 10.10. This page referring to ASan seems to indicate that it can do everything Valgrind’s Memcheck can, at less of a runtime performance cost, but I’m not sure how true this is exactly.


A much more primitive tool for finding leaks from the command line, BSD’s have leaks.

1 2 3 MallocStackLogging=1 ./a.out leaks a.out ... Profilers Perf

Perf, and Brendan Gregg’s tools for emitting SVG flamegraphs from the output are helpful for finding where time is spent in a program. In fact, there are numerous perfomance analysis tools that are Linux specific. My recommendation is spend some time on Brendan Gregg’s blog.


OSX doesn’t have the same tooling as Linux, but DTrace was ported to it. I’ve used it to find sampling profiles of my code before. Again, Brendan Gregg’s blog is a good resource; there are some fantastic DTrace one liners.

Debuggers lldb

lldb is analogous to gdb. I can’t say I have enough experience with LLDB and GDB to note the difference between the two, but LLDB did show the relative statements forward and back from the current statement by default. I’m informed by my friends/mortal enemies using emacs that this is less of an issue when using emacs/gdb in combination.

Fuzzers American Fuzzy Lop

American Fuzzy Lop (AFL) is a neat program that performs fuzzing on programs that take inputs from files and repeatedly runs the program, modifies the input trying to get full code coverage, and tries to find crashes. It’s been getting lots of attention lately, and while I haven’t used it myself yet, it seems like a very powerful tool. Mozilla employs the use of fuzzers on their JavaScript engine, for instance (not AFL, but one developed in house).

Disassemblers gobjdump

If you really need to make sure the higher level code you’re writing is getting translated into the assembly your expecting, gobjdump -S will intermix the emitted binary’s disassembled assembly and the source code. This was used extensively while developing my Brainfuck JIT.


Hopefully you learned of some useful tools that you should know about when working with C or C++. What did I miss?

Mike Hommey: Firefox nightlies for Linux are now using Gtk+3

Mozilla planet - vr, 24/07/2015 - 02:25

As of last nightly (2015-07-23), Firefox for Linux is using Gtk+3 instead of Gtk+2.

Thanks to the recent efforts of Andrew Comminos, all remaining test failures are gone and mozilla-central now defaults to Gtk+3 builds. Some jobs on treeherder are still not converted, but this will come soon (bug 1186748).

If you’ve been using elm builds for dogfooding, you should be automatically switched to standard nightlies today or tomorrow. The elm branch will be recycled to do Gtk+2 builds so that they keep working. Those builds won’t be auto-updating, so don’t use them.

David Burns: Microsoft ship a WebDriver implementation

Mozilla planet - do, 23/07/2015 - 22:19

Microsoft, the people still claim to be evil (who are actually big proponents of the the The Open Web), have... (wait for it...) SHIPPED. AN. IMPLEMENTATION. OF. WEBDRIVER!

At GTAC in California in 2011, Simon Stewart and I discussed that the Selenium project was at a crossroads (I am pretty sure beer was involved). We could ,and should, move this to the browser vendors. We had seen how in April the Chrome team had shipped their implementation and the Selenium project then deleted its implementation. I am pretty sure Daniel (Wagner-Hall) was glad to see it go.

In that time to now we have seen Mozilla get Marionette into Firefox and into release branches since Firefox 24 while slowly working on it (as well as Firefox OS support). We have seen Blackberry ship a version for the browser on their devices. We have seen mobile implementation with iOS-Driver, Selendroid and Appium.

The Spec is on track to be put forward for Recommendation by the end of the year. All the dreams that we (the Selenium Development team (my BFFs)) had are slowly coming true. This ship might be slow moving but it's mostly because some companies haven't always seen the value.


.@kylealden I raise a drink to the @MSEdgeDev team (esp @thejohnjansen) for helping make this happen @jimevansmusic

About:Community: Ten years of evolution of MDN

Mozilla planet - do, 23/07/2015 - 20:22

Logo for MDN 10 year anniversaryThis week marks the tenth anniversary of Mozilla Developer Network (MDN) as a wiki. This post offers a deep dive into where MDN came from, how it has evolved in various ways, and where it may be going.

(This post is based in large part on a round table discussion about MDN that was held during the “Hack on MDN” weekend in Berlin in April 2015, and on Florian Scholz’s history of MDN’s JavaScript documentation.)

What is MDN today?

For many web developers, MDN is the reference manual for the Web, the place they go to look up or learn about open web technologies. MDN offers much more than that. It is a resource for learning about the Web, and a place for developers to share their skills and knowledge. MDN’s strength lies in its openness, where anybody can help make the resources incrementally better, or substantially better. MDN can also encourage the growth of web technologies into new spaces from where they’ve been in the past.

MDN is a community of programmers, writers, and localizers. A few of these are paid staff of Mozilla, but they are a subset of the larger community of people who make small or large contributions.

One of the coolest things for those who contribute to MDN is that every time we talk to developers, they tell us how much they love MDN. It’s not, “Oh MDN is kind of cool,” or “It’s great.” The response is: “I love MDN. It’s the best resource out there.” It’s tremendously gratifying to feel that you are part of something that people really love.

Who is MDN for?

MDN serves a variety of audiences:

  • Web developers, first and foremost
  • People who want to teach themselves about web development
  • Teachers of web development skills and concepts
  • Developers in the ecosystem of Mozilla products, such as Firefox add-ons, and Firefox OS apps
  • Developers working on the Mozilla codebase
Beginnings of MDN

The site that became MDN, or “Devmo,” started as a redirect to a developer-oriented page on the main site. Later that content was moved over to Devmo; it contained primarily information for developers contributing to the Mozilla codebase.

Just as the Mozilla project emerged from the remains of Netscape, also MDN as we know it began with documentation originally written at Netscape. The site known as “Netscape DevEdge” documented web technologies, such as JavaScript, and other things that were implemented in Netscape products. After Netscape was acquired by AOL, the DevEdge site eventually was shut down, and that information disappeared from the Web.

Mitchell Baker (Chair of Mozilla) and others from Mozilla worked out an arrangement with AOL to release the DevEdge content, which she announced in February 2005. At the same time, Deb Richardson was hired to migrate and curate the DevEdge content into Devmo.

Mitchell and Deb made the decision to put the content into a wiki, to enable open contributions to maintain and update the content. Previously, the DevEdge content was in a CVS source control system, and published as a static site. Using a wiki for documentation was a novel concept at the time, and it took a while for some core developers within the Mozilla project to warm to this way of working. However, others quickly embraced the idea, and the many of the earliest contributors to the Devmo wiki were developers who were active elsewhere in the Mozilla project.

Deb and some volunteers spent a few months mining and migrating the still-useful content from DevEdge, working on a test server. This effort was still in progress when the content was migrated to the Devmo site, now titled “Mozilla Developer Center” or “MDC” in July 2005. We mark this as the starting point of what we now call Mozilla Developer Network.

Platform evolution

MDN has lived on three different wiki platforms in the course of its history: first MediaWiki, then MindTouch DekiWiki, and now Kuma, a Mozilla-developed platform. Looking at the technical infrastructure is interesting not just from a technical point of view, but also because technology influences social structures like community.


The wiki platform used for the first iteration of MDC was MediaWiki, the open source software that underlies Wikipedia. It was the most robust and widely-used wiki at the time. The Devmo project began to discover that software designed for writing a general-purpose encyclopedia was not necessarily ideal for writing developer-oriented technical documentation. For example, it did not handle code examples well, reformatting them to be unreadable. Mozilla tried to fix such issues by creating its own fork of MediaWiki, which then ended up being quite difficult to maintain.

On the level of contributions, using MediaWiki was initially an advantage, because many technical people were already familiar with how to use it. However, the project eventually reached a plateau, where it became difficult to keep contributors coming back. This, combined with the technical quirks, led to a search for a more user-friendly platform.


After an evaluation process that looked at all the wiki products available on the market (not just open source ones), the choice was made of DekiWiki by MindTouch. One advantage of DekiWiki was that the source format for articles was HTML, rather than wiki markup. It seemed a logical choice for a site targeting web developers, to have the source format be a standard web language. This required migrating all of the content from MediaWiki markup format to HTML, which was a major migration project. The choice of DekiWiki was announced in November 2007, and the site switched to it in August 2008.

While DekiWiki was a quality product, one way that the selection process was flawed was that it did not include a major group of stakeholders: volunteers who contributed to the site. The rate of contribution nose-dived, because the platform was not embraced by the contributor community. In particular, localization communities, who translated the content into various languages other than English, were severely disrupted. They had built tools and processes around working with MediaWiki, and these tools didn’t work with DekiWiki. After a few months, many of these groups simply disbanded and decided not to contribute any more, with the result that translated documentation started to become stale, and became more and more out of date over time.

DekiWiki was also written in C#, and designed to run in a Microsoft .NET environment. This was a mismatch with Mozilla’s technical infrastructure, which is Linux-based. Trying to run DekiWiki on Mono led to a great deal of instability, with the site being down for days and weeks at times.

These issues, after a couple of years, led to looking for another solution. The best candidates on the market were still MediaWiki and DekiWiki. Now that the content was all written in HTML, migrating back to MediaWiki markup syntax was not feasible. No product seemed suited to the specific needs of an open developer documentation site, so Mozilla decided to create its own.


The current platform for MDN, known as Kuma, is written in Python with Django. It started as a fork of Kitsune, the platform for the Mozilla support site, and was adapted to the needs of a wiki site for developers rather than end users. (Also, “kitsune” means “fox” in Japanese, and “kuma” means “bear”. Because users : foxes :: developers : bears, right?)

Like DekiWiki, Kuma uses HTML as the source format for the content. The migration effort in this case was converting the scripts and macros used on the site. DekiWiki used “DekiScript,” based on Lua, while Kuma introduced KumaScript, which is based on JavaScript, using Node.js. KumaScript is the brainchild of developer Les Orchard. As with creating content in HTML, KumaScript means that MDN is implemented using the same technologies that it documents, and that its contributors are familiar with. It was possible to migrate about 70% of the existing macros automatically, but the rest had to be manually converted.

The goal when launching the Kuma platform was to achieve feature parity with the DekiWiki implementation of MDN. The content was migrated to the new system, and changes from the production server were periodically updated on the Kuma staging server. Thus, the Kuma instance was kept in sync with the production DekiWiki server. While the months leading up to the launch of Kuma were involved a great deal of migration work, the actual launch was very smooth. A routing switch was flipped, and traffic shifted to the new site seamlessly, without even disrupting login sessions.

Community evolution

From the beginning, the community for the DevMo site grew organically, starting with contributors who were already active in other parts of the Mozilla project. Like other areas of Mozilla, communication happens through a mailing list and IRC chat channel. By mid-2007, contributions were typically 250 per month. As mentioned before, the migration to Dekiwiki led to a dramatic drop-off in localization contribution, and total contribution declined as well.

MDN doc sprint, Paris 2010

As part of an effort to engage the community more actively, I (Janet Swisher) was hired as a staff technical writer in mid-2010. I brought experience with open source developer documentation, and in particular, experience with the “book sprints” methodology used by the FLOSS Manuals project to produce manuals for free software in five days or less. The first MDN “doc sprint” took place in October 2010, in the Mozilla Paris office. Doc sprints bring together a number of MDN contributors, either physically or virtually, for focussed, collaborative work, typically over a weekend. These were held about once a quarter for about three years. More recently, they have evolved into less frequent but broader “Hack on MDN” events, whose scope includes hacking on the platform or tools, as well as on content, to make them more attractive to developers.

In addition, the MDN community holds a number of regular online meetings, both for general information, and for tracking specific projects. These community activities, as well as the migration to Kuma in 2012, have led to a significant increase in contributions, now around 1000 per month.

Branding evolution

In the beginning, the DevMo site was known as “Mozilla Developer Center.” At first, it simply sported that title, with a simple skin on MediaWiki. With the move to DekiWiki, the word “Mozilla” became the Mozilla wordmark, followed by “<developer center/>”, to convey slightly more webbiness.

Wordmark for Mozilla Developer Center

Wordmark for Mozilla Developer Center

In September 2010, the name of the site was changed from “Mozilla Developer Center” to “Mozilla Developer Network” or MDN. This change was met with some skepticism from the developer audience at the time, though by now they simply accept MDN as MDN. The visual design of the site changed at the same time, to a darker theme, and MDN acquired a logo, the “robot dino,” which it had never had before.

MDN robot dino logo

MDN robot dino logo

Along with these visual changes, features were added to the site to broaden its scope beyond just documentation. One successful feature is known as “Demo Studio”, an area where developers can upload code demos, share them, and show them off.

When MDN migrated from DekiWiki to Kuma, the visual appearance was preserved, so there was very little visual difference between the pre- and post-migration sites. After six to eight months of bug-fixing on Kuma, a project was started to change not only the visual design, but also the content structure. These changes were rolled out using feature flags, to users who chose to be beta testers. Thus, while most users continued to see the old design, while beta testers saw and tested the new visuals and structure. “Launch day” for the redesign consisted of simply flipping a switch in the database to make the new features visible to everybody.

The redesign brought not only a new logo, the dino-head-map that we see today, but also structural features like the navigation sidebar, which varies depending on which content area an article is in. In localized pages, items in the sidebar that are not yet translated link to their English versions, and show an invitation to translate them.

Content evolution

We mark the start of MDN “as we know it” from the acquisition and republication of the Netscape DevEdge content in 2005. But in the early days, the content was very slanted toward Mozilla products and technology. Not only was there documentation of XUL and internal Mozilla APIs (which are still there), but documentation of web technologies tended to be focused on Mozilla and Firefox, for example, with big banners like “works in Firefox 2.0″ or explanations of Gecko’s support of a feature in the middle of an otherwise neutral article.

As Mozilla began engaging more actively with the MDN community in 2010, community members began to express a vision of MDN as a vendor-neutral resource for web developers, whatever browsers they are targeting. Adopting this as a strategy required a lot of clean-up effort to remove Firefox-specific content from articles about web standards, and to create the compatibility tables that exist now, with information about all major browsers. Not coincidentally, as the content on MDN became more browser-agnostic, MDN started seeing contributions from other organizations.

MDN today and tomorrow

Two current projects on MDN are having a major impact on the shape of MDN in the near to medium term: the Learning area, and the compatibility data project.

MDN’s information about web technologies has long been a resource for experienced web developers. But it has poorly supported beginners to web development. The aim of the Learning area is to change that by offering tutorials and other resources to people who want to teach themselves about web development. This effort is happening in response to surveys we’ve done of our audience, who reported basic learning material as a significant gap. The Learning area project has been underway for about a year, and in that time has created a large Glossary about web technology concepts, and a number of new tutorials, corresponding to the Web Literacy Map developed by the Mozilla Foundation. The Learning area is a great opportunity to get started in contributing to MDN, since learners and teachers are as needed as technical experts.

Currently, data on MDN about browsers’ compatibility with web technology features is maintained in tables on the relevant pages. The data is pretty good, thanks to many, many crowd-sourced contributions. But this approach is not very sustainable or maintainable; for example, every table must be replicated on all localized versions of the page. The compatibility data project aims to improve the quality of the data, make data contribution easier, make access to the data easier, and allow reuse of the data, through a centralized data store. This project is action-driven rather than time-bound; contributions and involvement are welcome.

MDN in 10 years?

MDN as it exists today is quite different from its beginnings ten years ago. The Web has evolved, Mozilla has evolved, and MDN has evolved. We can expect even greater changes in the next ten years. Perhaps the vision of a direct brain interface to virtual reality “cyberspace” will finally come to pass. We know for sure there will be many more web developers, many more types of devices, and many standards that are not yet written.

Some things won’t change: Mozilla’s mission will continue to be to work towards an Internet that is a global public resource, open and accessible for all. MDN will continue to be a means towards that mission, by providing resources to enable anyone to become a creator of the Web, and to develop on the Web as a primary platform. MDN’s content, no matter how it’s delivered, will continue to be contributed by a global community of people who are passionate about learning and sharing knowledge about the Web.

Andreas Tolfsen: Optimised Rust code in Gecko

Mozilla planet - do, 23/07/2015 - 20:10
Rust Rust wave by Glen Scott (CC BY-NC 2.0) Optimised Rust code in Gecko

Following bug 1177608, Rust code in Gecko is now compiled with optimisation by default.

Compilation of Rust components can be enabled by adding ac_add_options --enable-rust to your mozconfig file. For now there’s only limited usage of Rust in Gecko, but you can take a look at the bindings for the MP4 encoder if you’re interested. This is much thanks to the work of Ralph Giles.

Since optimised compiles are the default, you will now also get optimised output from rustc. You can disable this by setting ac_add_options --disable-optimize. This disables compilation for all cc, c++, and rustc compilers.

Next up is adding debug symbols, assertions, and adding some Rust autoconf macros.

The Mozilla Blog: MDN celebrates 10 years of documenting YOUR Web

Mozilla planet - do, 23/07/2015 - 11:09

Today, Mozilla proudly celebrates the 10th anniversary of the Mozilla Developer Network, one of the richest and also one of the few multilingual resources on the Web for documentation. It started in February 2005, when a small team dedicated to the open Web took DevEdge (Netscape’s developer materials) and set out to create an open, free, community-built online resource for all Web developers. Just a couple of months later, on 23 July, 2005 the original MDN wiki site launched and has evolved steadily ever since for the convenience and the benefit of its users.

Today, ten years later, not only has the amount of documentation grown – 34,500 documents and climbing – but also MDN’s global volunteer community is bigger than ever. Currently, MDN has more than 4 million users and over 1000 volunteer editors per month creating and translating documentation, sample code, tutorials and other learning resources for all open Web technologies, including CSS, HTML, JavaScript and everything that makes the open Web as rich and versatile as it is.


For a wide range of Web developers, from learners to hobbyists to full-time professionals, MDN provides useful explanations for coding practice. It aims to inspire ideas, encourage collaboration, innovation and ultimately, foster the growth of the open Web. Moreover, as the digital industry flourishes and the demand for coding skills at young age rises, the importance of well-organized resources like MDN grows exponentially. That is why in 2014 MDN started to feed and expand all its learning pages into a “Learn the Web” area for beginning web developers, including a web terminology glossary, which MDN’s technical writers and volunteers will continue to develop over the next years.

All these efforts, which would not be possible without the active MDN volunteer base, are being greatly acknowledged by developers from all over the world who would not be doing what they do without MDN – or at least not as good.

Let’s hear it for MDN!
