It will be faster to just call KeyString() once, bind it to a local variable here. (also easier on memory)

I think we should make sure that the name pairing still works properly with this change, so that links with the same name (or 'path' within the object) still create the same resulting 'change' object |
|
I believe that the name matching property will be maintained with this pr, as long as the Links() function is only a function of the ipld topology of the object. I will write a test to verify this. |

Looks right. The Name property of links is a protonode thing (that needs to die).

Hooray! My first commits to go-ipfs! :-) |
