By removing the transaction listeners from surface fragments we no longer have to make sure they are always manually destroyed. In order to retain the functionality of having fragments update with transactions elsewhere we keep a pointer to a place in the new complete history stack in the surface. The complete history stack records all transactions, even undone ones. Whenever getRange is called we replay all transactions in the complete history (in the correct order) since the fragment was last updated. Also in this commit: * Updated Format/IndentationAction to test undo(). This increases coverage of surface fragment behaviour. * .range is always accessed by .getRange now, although as an optimisation we can use the noCopy mode when we a sure the returned range will not be modified. * Added undo test to .update (previously .onTransact) Bug: 47343 Change-Id: I9e9818da1baa8319a3002f6d74fd1aad6732a8f5
