[Bitcoin-development] Bitcoin development (testing & where to get Wallet code)

[Bitcoin-development] Bitcoin development (testing & where to get Wallet code)

[Caleb Roger Davis]

[-- Attachment #1: Type: text/plain, Size: 1224 bytes --]

I have several Bitcoin contributions I would like to make, mostly for
learning purposes to get started:


   1. I would like to contribute to unit and/or other types of tests
   (code), not production code.
   2. I would like to understand the Bitcoin code (as much as possible from
   top to bottom)
   3. I would like to write a Bitcoin wallet in another language (so would
   like to know where to get the "Bitcoin - Core Wallet" code, but not sure
   where it resides.

I am a seasoned software developer, but I do need direction on where to get
started.  If there is a wiki doc for new developers that would reduce my
searching and experimentation that would be great.

For each of the three items above, I would like to know the tools and
frameworks I would need to understand and initially work on tests ( how to
run the existing tests to get code coverage and find where coverage is
needed, what is the preferred IDE and full development stack etc ), and
also where to get started looking at the bitcoin core code and also the
wallet code (where is the initial starting point and then I could trace
from there ).

Is there a separate area (github & mailing list) for core wallet
development?

Sincerely,

May I ask you which language? I'd love to implement Bitcoin in Clojure or Scheme.

Yes, I was thinking something on the JVM, I have a big interest in Clojure
right now (am a long time Java dev, since 1996).

I do not know if I want to tackle writing bitcoin in Clojure, but I want to
create a tool kit first to learn more about how it works.

Are you aware of bitcoinj?

http://bitcoinj.github.io/

It contains everything to plug together a basic SPV wallet and runs in
the JVM.

Low-level unit tests are in `src/test`. These use the boost
unit-testing framework. You can run them with 'make check' or
`src/test/test_bitcoin`.

High-level RPC tests are in `qa/rpc-tests`. These are Python scripts
that can be invoked manually, and are based on our own simple
framework.

There is also a java-based 'comparison tool' that tests high-level
behavior with regard to the block chain. It is based on bitcoinj and
acts as an external node. This is not part of the github bitcoin
repository itself, but of bitcoinj (AFAIK).

See https://www.bitcoin.org/en/developer-guide

All of the wallet code is in `src/wallet.cpp` and `src/walletdb.cpp`.
If the purpose is just studying, the bitcoin core wallet is not the
most readable wallet code around, and also hard to port as it relies
on a full node in the same process. It's better to look at SPV
wallets, for example the bitcoinj-based ones.

Something like that would be useful, yes.

If you want to work on Bitcoin Core, a Linux box (or VM) is the best
development environment. Getting started building on WIndows or Mac is
harder (but possible). There is work in progress to make building the
dependencies easier for those.
