bors-servo ddce8b8fa0 auto merge of #1152 : ILyoan/servo/parallel_selector_matching, r=SimonSapin 
This an attempt to parallelize selector matching.

Approach
* Let the `match_subtree` spawn limited number of tasks.
* Each of them takes a list of nodes that is uniformly distributed
* And then each task does the selector matching for every single node in its list.

(Not sure if this is worthwhile for long term especially considering CSS optimizing techniques such as ancestor filter or style sharing)

Benchmark from my machine (LayoutSelectorMatchCategory) (intel i7 3.4GHz * 8, linux x86_64)
* src/test/demo.html
 * original: 0.07ms
 * parallel: 0.20ms
* perf-rainbow.html
 * original: 485ms
 * parallel: 245ms
* A test page with 15000 nodes and 3000 CSS selector(including inline style).
 * original: 140ms
 * parallel: 60ms

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 libfontconfig1-dev libgl1-mesa-dri libglib2.0-dev \
    xorg-dev msttcorefonts

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

Running

Commandline Arguments

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

Keyboard Shortcuts

  • Ctrl-L opens a dialog to browse to a new URL (Mac only currently)
  • Ctrl-- zooms out
  • Ctrl-= zooms in
  • Backspace goes backwards in the history
  • Shift-Backspace goes forwards in the history
  • Esc exits servo

Developing

There are lots of make targets you can use:

  • make clean - cleans Servo and its dependencies, but not Rust
  • make clean-rust - cleans Rust
  • make clean-servo - only cleans Servo itself (code in src/components
  • make clean-DEP - cleans the dependency DEP. e.g. make clean-rust-opengles
  • make bindings - generate the Rust WebIDL bindings
  • make DEP - builds only the specified dependency. e.g. make rust-opengles
  • make check-DEP - build and run tests for specified dependency
