The pathfinder has 3 types of cells (cPathCell).
1 - empty. m_IsSolid is false, m_IsSpecial is false. Air cells are always traversable by A*. 2 - occupied / solid. m_IsSolid is true, m_IsSpecial is false. Air cells are never traversable by A*. 3 - Special. m_IsSolid is true, m_IsSpecial is true. These cells are special: They may either behave as empty or as occupied / solid, depending on the mob's direction of movement. For instance, an airblock above a fence is a special cell, because when mobs attempt to travel to it by jumping, it acts as a solid. But when mobs fall and land on top of a fence, it acts as air. Special cells include: Doors, ladders, trapdoors, water, gates.
The main function which handles special blocks is SpecialIsSolidFromThisDirection. This function receives a BlockType, a meta, and a direction of travel, then it uses those 3 parameters to decide whether the special block should behave as a solid or as air in this particular direction of travel.
Currently, only fences and water are handled properly. The function always returns "true" (meaning: treat as occuiped/solid) for the rest of the blocks. This will be fixed once the physics engine issues are fixed.
