2014-07-22Fix bugs in caching layerMarc André Tanner1-8/+27
Thw lenght of the whole text (ed->size) also has to be updated. Also do not allocate changes if the operations are performed in the cache.

2014-07-21Introduce cache layerMarc André Tanner1-27/+108
If multiple consecutive modifications happen to lie within the same piece perform the operations "in place". In particular no new pieces will be allocated if the changes occur at the end of the most recently modified piece. In this case the piece is simply extended. However changes in the middle of a piece involve memove(3) calls which might hurt performance. Since no new pieces are created the changes can't be undone on an individual basis. The frontend should therefore call 'editor_snapshot' at appropriate times inorder to invalidate the cache.
