Missing block representation in Pure Python serializer #16

Closed Kiwonik closed 6 years ago

Kiwonik commented 6 years ago

In order to read (and filter) operations from main net node (as required by e.g. Populate Transaction issue of tinman https://github.com/steemit/tinman/issues/2) using block_api's get_block method a representation of block is needed in Pure Python serializer. The lacking functionality is block operation iteration that allows to get block's operations in form of python objects.

this should be very straightforward. can you point me to the exact definition of the block object in steemd?

goldibex commented 6 years ago

ping @Kiwonik

@goldibex That'd be signed_block (in protocol/block.hpp) having a container of signed_transaction (protocol/transaction.hpp) inheriting from transaction (same file) having a container of operation (protocol/operations.hpp) that need be iterated from the block's representation.

@goldibex I'm cancelling this issue and accompanying PR after I discovered they are based on some misunderstanding regarding the pure python serializer you wrote. I've just been explained by @mvandeberg that the serializer was never intended to be used the way I described in this issue - to create a python object representing a transaction for example, that allows to e.g. iterate all of the operations it contains (as python objects too). All I can get from the serializer is a sequence of bytes i.e. a binary representation and not an object (as in object oriented programming) representation. I'll get my results operating on JSON output of appropriate steemd api with no use of serializer.
