Implement iterable for headers

<!-- Please describe your changes on the following line: -->
These patches make Headers iterable based on #12819.

The expected wpt results are updated as well.

<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: -->
- [X] `./mach build -d` does not report any errors
- [X] `./mach test-tidy` does not report any errors
- [ ] These changes fix #__ (github issue number if applicable).

<!-- Either: -->
- [x] There are tests for these changes OR
- [ ] These changes do not require tests because web platform tests for Headers already exist. Expected test results are updated with this PR.

<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->

The Servo Parallel Browser Engine Project

Linux Build Status Windows Build Status

Servo is a prototype web browser engine written in the Rust language. It is currently developed on 64bit OS X, 64bit Linux, and Android.

Servo welcomes contribution from everyone. See CONTRIBUTING.md and HACKING_QUICKSTART.md for help getting started.

Visit the Servo Project page for news and guides.

Setting up your environment

Please select your operating system:

OS X

On OS X (homebrew)

brew install automake pkg-config python cmake
pip install virtualenv

On OS X (MacPorts)

sudo port install python27 py27-virtualenv cmake

On OS X 10.11 (El Capitan), you also have to install openssl

brew install openssl
brew link --force openssl

If you get this error during the brew link step:

Warning: Refusing to link: openssl

followed by a compile error not being able to find one or more openssl/ include files, you may want to try:

export DEP_OPENSSL_INCLUDE=/usr/local/include
./mach build ...

If you've already partially compiled servo but forgot to do this step, run ./mach clean, link openssl, and recompile.

On Debian-based Linuxes

sudo apt-get install git curl freeglut3-dev autoconf \
    libfreetype6-dev libgl1-mesa-dri libglib2.0-dev xorg-dev \
    gperf g++ build-essential cmake virtualenv python-pip \
    libssl-dev libbz2-dev libosmesa6-dev libxmu6 libxmu-dev \
    libglu1-mesa-dev libgles2-mesa-dev libegl1-mesa-dev libdbus-1-dev

If you are on Ubuntu 14.04 and encountered errors on installing these dependencies involving libcheese, see #6158 for a workaround.

If virtualenv does not exist, try python-virtualenv.

On Fedora

sudo dnf install curl freeglut-devel libtool gcc-c++ libXi-devel \
    freetype-devel mesa-libGL-devel mesa-libEGL-devel glib2-devel libX11-devel libXrandr-devel gperf \
    fontconfig-devel cabextract ttmkfdir python python-virtualenv python-pip expat-devel \
    rpm-build openssl-devel cmake bzip2-devel libXcursor-devel libXmu-devel mesa-libOSMesa-devel \
    dbus-devel

On Arch Linux

sudo pacman -S --needed base-devel git python2 python2-virtualenv python2-pip mesa cmake bzip2 libxmu glu pkg-config

On Gentoo Linux

sudo emerge net-misc/curl media-libs/freeglut \
    media-libs/freetype media-libs/mesa dev-util/gperf \
    dev-python/virtualenv dev-python/pip dev-libs/openssl \
    x11-libs/libXmu media-libs/glu x11-base/xorg-server

On Windows

Download Python for Windows here. This is required for the SpiderMonkey build on Windows.

Install MSYS2 from here. After you have done so, open an MSYS shell window and update the core libraries and install new packages. The extra step at the end is to downgrate GCC to 5.4, as the GCC6 versions in mingw currently fail to compile some of our dependencies. We are upgrading to a gcc-free build on Windows as soon as possible:

pacman -Su
pacman -Sy git mingw-w64-x86_64-toolchain mingw-w64-x86_64-freetype \
    mingw-w64-x86_64-icu mingw-w64-x86_64-nspr mingw-w64-x86_64-ca-certificates \
    mingw-w64-x86_64-expat mingw-w64-x86_64-cmake tar diffutils patch \
    patchutils make python2-setuptools
export GCC_URL=http://repo.msys2.org/mingw/x86_64/mingw-w64-x86_64-gcc
export GCC_EXT=5.4.0-1-any.pkg.tar.xz
pacman -U --noconfirm $GCC_URL-$GCC_EXT $GCC_URL-ada-$GCC_EXT \
    $GCC_URL-fortran-$GCC_EXT $GCC_URL-libgfortran-$GCC_EXT $GCC_URL-libs-$GCC_EXT \
    $GCC_URL-objc-$GCC_EXT
easy_install-2.7 pip virtualenv

Open a new MSYS shell window as Administrator and remove the Python binaries (they are not compatible with our mach driver script yet, unfortunately):

cd /mingw64/bin
mv python2.exe python2-mingw64.exe
mv python2.7.exe python2.7-mingw64.exe

Now, open a MINGW64 (not MSYS!) shell window, and you should be able to build servo as usual!

Cross-compilation for Android

Pre-installed Android tools are needed. See wiki for details

The Rust compiler

Servo's build system automatically downloads a Rust compiler to build itself. This is normally a specific revision of Rust upstream, but sometimes has a backported patch or two. If you'd like to know which nightly build of Rust we use, see rust-nightly-date.

Building

Servo is built with Cargo, the Rust package manager. We also use Mozilla's Mach tools to orchestrate the build and other tasks.

Normal build

To build Servo in development mode. This is useful for development, but the resulting binary is very slow.

git clone https://github.com/servo/servo
cd servo
./mach build --dev
./mach run tests/html/about-mozilla.html

For benchmarking, performance testing, or real-world use, add the --release flag to create an optimized build:

./mach build --release
./mach run --release tests/html/about-mozilla.html

Building for Android target

git clone https://github.com/servo/servo
cd servo

export ANDROID_SDK="/path/to/sdk"
export ANDROID_NDK="/path/to/ndk"
export ANDROID_TOOLCHAIN="/path/to/toolchain"
export PATH="$PATH:/path/to/toolchain/bin"

./mach build --release --android
./mach package --release --android

Rather than setting the ANDROID_* environment variables every time, you can also create a .servobuild file and then edit it to contain the correct paths to the Android SDK/NDK tools:

cp servobuild.example .servobuild
# edit .servobuild

Running

Use ./mach run [url] to run Servo. Also, don't miss the info on the browserhtml page on how to run the Browser.html full tech demo (it provides a more browser-like experience than just browsing a single URL with servo).

Commandline Arguments

  • -p INTERVAL turns on the profiler and dumps info to the console every INTERVAL seconds
  • -s SIZE sets the tile size for painting; defaults to 512
  • -z disables all graphical output; useful for running JS / layout tests
  • -Z help displays useful output to debug servo

Keyboard Shortcuts

  • Ctrl-- zooms out
  • Ctrl-= zooms in
  • Alt+left arrow goes backwards in the history
  • Alt+right arrow goes forwards in the history
  • Esc exits servo

Developing

There are lots of mach commands you can use. You can list them with ./mach --help.
