overflow correctly, and opportunistically lay out blocks in parallel even if floats are present. This commit fixes the `inline-height-test` in Acid2 by implementing proper overflow as well as the inline "strut". (See CSS 2.1 § 10.8.1.) Acid2 was accidentally being rendered properly before because tables' descendant flows were not being laid out properly. Display list building is now parallel and is done by bubbling up display items and layers from parent to child. Speedups of around 60%-70% are observed on Wikipedia with a 4-core HyperThreaded Core i7. More optimizations are possible; this is just a start. To minimize the amount of data that needs to be bubbled up, as well as to make proper handling of `overflow: hidden` clipping easier, the `StackingContext` abstraction is now purely internal to the display list. That is, instead of placing items into a stacking context directly, display items are placed into display lists alongside a stacking level. When a stacking context is complete, it is flattened with the the `flatten` method, which shuffles the display items that make up the context into their proper order while handling clipping properly. |

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 and 64bit Linux.
Servo welcomes contribution from everyone. See
CONTRIBUTING.md
for help getting started.
Prerequisites
On OS X (homebrew):
brew install https://raw.github.com/Homebrew/homebrew-versions/master/autoconf213.rb
brew install automake libtool pkg-config
On OS X (MacPorts):
sudo port install autoconf213
On Debian-based Linuxes:
sudo apt-get install autoconf2.13 curl freeglut3-dev libtool \
libfreetype6-dev libgl1-mesa-dri libglib2.0-dev xorg-dev \
msttcorefonts gperf g++ automake cmake
On Fedora Core:
sudo yum install autoconf213 curl freeglut-devel libtool \
freetype-devel mesa-libGL-devel glib2-devel libX11-devel \
gperf gcc-c++ rpm-build cabextract ttmkfdir
pushd .
cd /tmp
wget http://corefonts.sourceforge.net/msttcorefonts-2.5-1.spec
rpmbuild -bb msttcorefonts-2.5-1.spec
sudo yum install $HOME/rpmbuild/RPMS/noarch/msttcorefonts-2.5-1.noarch.rpm
popd
On Debian-based Linuxes (cross-compilation for Android):
sudo apt-get install autoconf2.13 curl libtool ia32-libs
And it needs pre-installed Android tools. See wiki for details
Servo builds its own copy of Rust, so there is no need to provide a Rust compiler.
Building
Servo cannot be built in-tree; you must create a directory in which to run configure and make and place the build artifacts.
git clone https://github.com/mozilla/servo.git
cd servo
mkdir -p build && cd build
../configure
make && make check
./servo ../src/test/html/about-mozilla.html
###Building for Android target
git clone https://github.com/mozilla/servo.git
cd servo
mkdir -p build && cd build
../configure --target-triples=arm-linux-androideabi --android-cross-path=<Android toolchain path> --android-ndk-path=<Android NDK path> --android-sdk-path=<Android SDK path>
make

Developing
There are lots of make targets you can use:
make clean
- cleans Servo and its dependencies, but not Rustmake clean-rust
- cleans Rustmake clean-servo
- only cleans Servo itself (code insrc/components
make clean-DEP
- cleans the dependencyDEP
. e.g.make clean-rust-opengles
make bindings
- generate the Rust WebIDL bindingsmake DEP
- builds only the specified dependency. e.g.make rust-opengles
make check-DEP
- build and run tests for specified dependency
The make check-*
targets for running tests are listed here
