[WIP] Implement BIP32 HD account class - 2 #31

sea212 · 2018-08-26T22:41:03Z

What was wrong?

Issue #24

How was it fixed?

I have created the hdaccounts.py file containing the class HDAccount(BaseAccount). I have defined the functions I will need and commented their meaning, usage and further steps. I have left TODOs which I will work on.
Question: Is it okay if I import the files "mnemonic.py" and "deterministic.py" from pybitcointools and if yes, do you want me to adapt them to reduce the overhead of the required libraries or do you want me to write them completely from scratch?

Note: I have an unusually high amount of work last week and in the coming week. I will spend just a couple of hours in the coming week, but continuous progress will be observable. Afterwards the progress will be significantly accelerated.

…at to do next

👍 as long as there is progress being made.

I think this is clear but adding pybitcointools as a dependency is off the table as it is unmaintained.

I would advocate porting over the necessary components (and cleaning them up). This would also include test cases to demonstrate how the various utils are intended to function.

I will do so.

…path to setup.py, debugged mnemonic.py to work with python3, adapted function commenting style for the most functions

sea212 · 2018-09-01T20:10:18Z

Today I have:

Implemented Init from mnemonic function and create Account function
Tested functionallity of Init and Create functions
Adjusted setup.py to include wordlist path and the containing wordlists
Debugged mnemonic.py to work with python3
Adapted the given function commenting style for almost every function

Output from the current tests:

…path argument support for init. Added and implemented decodePath(...) function to represent the derivation path as a string in format (m/)idx_0/.../idx_n . Added path property to return the string formatted derivation path. Added __repr__ and __str__, adjusted __eq__ and __hash__. Included (very basic) unit test for deriveChild(...) . Adapted function describing commenting style for every function.

…ort tells me the contrary

sea212 · 2018-09-05T00:09:22Z

I have completed all remaining tasks now (test and cleanup mostly), the HDAccount class is now complete and fully functional. Isort worked as excepted before and the automated tests found no issues, but since I added some more imports today the automated tests find errors. My local isort does tell me that the imports are fine. I have tried different options, like ignoring types, but I just can't get the automated testing tool to accept the file. Sadly the error report does not give me any hint what is not ok in detail. Do you know what could be the problem?

apart from that, are you content with this result and can I submit it to gitcoin?
