Core db remove legacy phrases (#2468) 
* Rename `newKvt()` -> `ctx.getKvt()`

why:
  Clean up legacy shortcut. Also, the `KVT` returned is not instantiated
  but refers to the shared `KVT` that resides in a context which is a
  generalisation of an in-memory database fork. The function `ctx`
  retrieves the default context.

* Rename `newTransaction()` -> `ctx.newTransaction()`

why:
  Clean up legacy shortcut. The transaction is applied to a context as a
  generalisation of an in-memory database fork. The function `ctx`
  retrieves the default context.

* Rename `getColumn(CtGeneric)` -> `getGeneric()`

why:
  No more a list of well known sub-tries needed, a single one is enough.
  In fact, `getColumn()` did only support a single sub-tree by now.

* Reduce TODO list

Raw Blame History

  • Check whether HashKey can be reduced to a simple 32 byte array (see desc_identifiers.nim)

  • Re-visit delTree(). Suggestion is deleting small trees on the memory later, otherwise only deleting the root vertex (so it becomes inaccessible) and remember the follow up vertices which can travel through the tx-layers to be picked up by the backend store.

  • Mental note: For proof-mode with pre-allocated locked vertices and Merkle keys, verification of a partial tree must be done by computing sub-tree keys at the relative roots and comparing them with the pre-allocated Merkle keys.
