bors-servo 7ece5f92db auto merge of #1971 : Constellation/servo/quick-fail-selector-matching, r=SimonSapin 
Restart selector matching from an appropriate selector

Introducing 3 matching failure statuses,

+ NotMatchedGlobally
+ NotMatchedAndRestartFromClosestDescendant
+ NotMatchedAndRestartFromClosestLaterSibling

When NotMatchedGlobally appears, stop selector matching completely since
the succeeding selector never matches.
It is raised when
+ Child selector cannot find the candidate element
+ Descendant selector cannot find the candidate element

When NotMatchedAndRestartFromClosestDescendant appears, the selector
matching does backtracking and restarts from the closest Descendant
selector.
It is raised when
+ NextSibling selector cannot find the candidate element.
+ LaterSibling selector cannot find the candidate element.
+ Child selector doesn't match on the found element.

When NotMatchedAndRestartFromClosestLaterSibling appears, the selector
matching does backtracking and restarts from the closest LaterSibling
selector.
It is raised when
+ NextSibling selector doesn't match on the found element.

For example, when the selector "d1 d2 a" is provided and we cannot *find*
an appropriate ancestor node for "d1", this selector matching raises
NotMatchedGlobally since even if "d2" is moved to more upper node, the
candidates for "d1" becomes less than before and d1 .

The next example is siblings. When the selector "b1 + b2 ~ d1 a" is
providied and we cannot *find* an appropriate brother node for b1,
the selector matching raises NotMatchedAndRestartFromClosestDescendant.
The selectors ("b1 + b2 ~") doesn't match and matching restart from "d1".

The additional example is child and sibling. When the selector
"b1 + c1 > b2 ~ d1 a" is provided and the selector "b1" doesn't match on
the element, this "b1" raises NotMatchedAndRestartFromClosestLaterSibling.
However since the selector "c1" raises
NotMatchedAndRestartFromClosestDescendant. So the selector
"b1 + c1 > b2 ~ " doesn't match and restart matching from "d1".

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++

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

The make check-* targets for running tests are listed here
