Nicholas Nethercote d7f8d7b8ae servo: Merge #18400 - Measure selectors (from nnethercote:measure-selectors); r=heycam
This patch adds measurement of Selectors within StyleRule. This requires
exposing the pointer within ThinArc.

The patch also adds measurement of the several CssRule variants, in order to
measure nested CssRules (and PropertyDeclarationBlocks) within them:
DocumentRule, MediaRule, PageRule, SupportsRule.

The Servo Parallel Browser Engine Project

Linux Build Status Windows Build Status Changelog #228

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 yasm
pip install virtualenv

On OS X (MacPorts)

sudo port install python27 py27-virtualenv cmake yasm

On OS X >= 10.11 (El Capitan), you also have to install OpenSSL

brew install openssl

export OPENSSL_INCLUDE_DIR="$(brew --prefix openssl)/include"
export OPENSSL_LIB_DIR="$(brew --prefix openssl)/lib"

./mach build ...

If you've already partially compiled servo but forgot to do this step, run ./mach clean, set the shell variables, and recompile.

On Debian-based Linuxes

sudo apt install git curl freeglut3-dev autoconf libx11-dev \
    libfreetype6-dev libgl1-mesa-dri libglib2.0-dev xorg-dev \
    gperf g++ build-essential cmake virtualenv python-pip \
    libssl1.0-dev libbz2-dev libosmesa6-dev libxmu6 libxmu-dev \
    libglu1-mesa-dev libgles2-mesa-dev libegl1-mesa-dev libdbus-1-dev

If you using a version prior to Ubuntu 17.04 or Debian Sid, replace libssl1.0-dev with libssl-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 ncurses-devel

On openSUSE Linux

sudo zypper install libX11-devel libexpat-devel libbz2-devel Mesa-libEGL-devel Mesa-libGL-devel cabextract cmake \
    dbus-1-devel fontconfig-devel freetype-devel gcc-c++ git glib2-devel gperf \
    harfbuzz-devel libOSMesa-devel libXcursor-devel libXi-devel libXmu-devel libXrandr-devel libopenssl-devel \
    python-pip python-virtualenv rpm-build glu-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 (MSVC)

  1. Install Python for Windows (https://www.python.org/downloads/release/python-2711/). The Windows x86-64 MSI installer is fine. You should change the installation to install the "Add python.exe to Path" feature.

  2. Install virtualenv.

In a normal Windows Shell (cmd.exe or "Command Prompt" from the start menu), do:

pip install virtualenv

If this does not work, you may need to reboot for the changed PATH settings (by the python installer) to take effect.

  1. Install Git for Windows (https://git-scm.com/download/win). DO allow it to add git.exe to the PATH (default settings for the installer are fine).

  2. Install Visual Studio Community 2017 (https://www.visualstudio.com/). You MUST add "Visual C++" to the list of installed components. It is not on by default.

If you encountered errors with the environment above, do the following for a workaround:

  1. Download and install Build Tools for Visual Studio 2017
  2. Install python2.7 x86-x64 and virtualenv
  3. Since mach.bat cannot find the prompt, you should execute Developer Command Prompt for VS 2017 manually in the Windows menu. ( You may need to choose the type, such as x86_x64 Cross Tools Command Prompt for VS 2017, manually if it cannot recognize type correctly. )
  4. cd to/the/path/servo
  5. python mach build -d

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-toolchain.

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

Or on Windows MSVC, in a normal Command Prompt (cmd.exe):

git clone https://github.com/servo/servo
cd servo
mach.bat build --dev

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

Checking for build errors, without building

If youre making changes to one crate that cause build errors in another crate, consider this instead of a full build:

./mach check

It will run cargo check, which runs the analysis phase of the compiler (and so shows build errors if any) but skips the code generation phase. This can be a lot faster than a full build, though of course it doesnt produce a binary you can run.

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. Like so,

./mach run https://www.google.com

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.
