All these significantly increase the development and maintenance costs (the recent efforts on enabling of Tizen platform security mechanisms in Crosswalk is a good example of how having the Shared process model caused a lot of troubles) Affected components: Crosswalk on Tizen, Crosswalk application tools (xwalk launcher, xwalkctl) This change will apparently modify also the Tizen Crosswalk command line interface (for example remote debugging cmd line options) whereas xwalk binary will be invoked directly. Target platform: Tizen Implementation plan: 1) Add the Tizen appcore-related logic and other functionality from xwalk-launcher to BP 2) Make the necessary modifications in Tizen so that it does not rely on the Shared process model any more (e.g. launches xwalk instead of xwalk-launcher) 3) Merge EP and GP into BP -- make it Dual process model 4) Clean up tons of unused code, including removal of xwalk-launcher (yay!)
