Version Information

  • vyper Version: 0.1.0b4
  • OS: osx
  • Python Version: 3.6.3

What's your issue about?

I'm going to update ERC20 in example repository to the latest Vyper version (0.1.0b4) and working on the test of this. I tried the current tests in tests/examples/tokens/ERC20_solidity_compatible with python run_tests.py command but it causes this error.

(vyper) nrryuya:ERC20_solidity_compatible nrryuya1$ python run_tests.py 

Failed to import bitcoin. This is not a fatal error but does
mean that you will not be able to determine the address from
your wallet file.

How can it be fixed?

As the first AttributeError: module 'vyper.compiler' has no attribute 'Compiler' shows, Compiler object is removed from vyper/compiler.py in this commit. We need to fix this somehow?

EDIT: I added the Compiler class in compiler.py and AttributeError: module 'vyper.compiler' has no attribute 'Compiler' disappeared. However, AttributeError: can't set attribute still remains.

Before starting with this PR, just wait for #1089 to be merged. As it #1089 changes the compiler interface slightly.

This is also documented here (but it's not rendered correctly at docs ?)

I'm not sure but these tests for bad_code is not necessary anymore?

I think it actually is required, the reason is that one needs bad contract to access the specific branch.

Thanks. The code self.num_issued = uint256_add which is replaced to generate the bad_code doesn't exists so we need to modify that.

Also, AFAIK deposit & withdraw which allow users to exchange token at the ratio 1 wei = 1 token anytime is not a standard implementation. To implement mint and burn instead will make it more generally reusable while it's still enable the "bad code tests".

I want to refactor ERC20 example as follows.

  • Unify three types of ERC20 into one which has mint & burn, also name, symbol and decimal like vypercoin.vy
  • Reuse ERC20_solidity_compatible tests (because they are good one which tests for full branch/decision, statement coverage) with some modification
  • Add the tests to CI

I wonder rewriting ERC20_solidity_compatible tests with pytest, which makes it simple to add to CI and remove the dependency on pyethereum.
