Several issues are addressed in this commit: * Inline flows now bubble up their absolute descendants instead of making the inline flow the containing block for them. (In the future, we will need to make the inline flow *sometimes* be the containing block for them, but for now it improves sites to unconditionally bubble up.) * Fragments now look at their inline fragment context to determine whether they are positioned. * Inline flows now push the stacking-relative position of the absolute containing block down to their inline-block fragments. * Inline absolute hypothetical fragments can be containing blocks. * Fixes the logic in `containing_block_range_for_flow_surrounding_fragment_at_index`. The condition to determine whether fragments are positioned was inverted! * `Descendants`/`AbsDescendants` has been refactored in order to become more friendly to inline absolute containing blocks in the future. Improves the inline position of the green drop-down arrow in the Google SERPs. (The block position is still wrong.) |

The Servo Parallel Browser Project
Servo is a prototype web browser engine written in the Rust language. It is currently developed on 64bit OS X, 64bit Linux, Android, and Gonk (Firefox OS).
Servo welcomes contribution from everyone. See
CONTRIBUTING.md
for help getting started.
Prerequisites
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 Debian-based Linuxes:
sudo apt-get install curl freeglut3-dev \
libfreetype6-dev libgl1-mesa-dri libglib2.0-dev xorg-dev \
gperf g++ cmake python-virtualenv \
libssl-dev libbz2-dev libosmesa6-dev libxmu6 libxmu-dev libglu1-mesa-dev
On Fedora:
sudo dnf install curl freeglut-devel libtool gcc-c++ libXi-devel \
freetype-devel mesa-libGL-devel glib2-devel libX11-devel libXrandr-devel gperf \
fontconfig-devel cabextract ttmkfdir python python-virtualenv expat-devel \
rpm-build openssl-devel cmake bzip2-devel libXcursor-devel libXmu-devel mesa-libOSMesa-devel
On Arch Linux:
sudo pacman -S --needed base-devel git python2 python2-virtualenv mesa cmake bzip2 libxmu
Cross-compilation for Android:
Pre-installed Android tools are needed. See wiki for details
Using Virtualbox:
If you're running servo on a guest machine, make sure 3D Acceleration is switched off (#5643)
The Rust compiler
Servo's build system automatically downloads a snapshot 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 the snapshot revision of Rust which we use, see
rust-snapshot-hash
.
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
ANDROID_TOOLCHAIN=/path/to/toolchain ANDROID_NDK=/path/to/ndk PATH=$PATH:/path/to/toolchain/bin ./mach build --android
cd ports/android
ANDROID_SDK=/path/to/sdk make install
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.
Commandline Arguments
-p INTERVAL
turns on the profiler and dumps info to the console everyINTERVAL
seconds-s SIZE
sets the tile size for painting; defaults to 512-z
disables all graphical output; useful for running JS / layout tests
Keyboard Shortcuts
Ctrl-L

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