upgrade truffle

[jellegerbrandy]

We are using truffle 4.1.6

upgradeing to 4.1.7 (which also upgrades solc to 0.4.23) breaks tests in paratii-js

Todo:

• reproduce the error from apratii-js in a test in paratii-contracts
• fix and upgrade :-)

Hi Jelle. If no one is working on it, i would like to start.

[jellegerbrandy]

You are very welcome!

[jellegerbrandy]

to reproduce these errors in paratii-js, the road to take is to install paratii-js according to the instructions there, upgrade the reference to paratii-contracts in package.json, run a yarn install, and then run the tests.

Yesterday i've followed these steps, but without change the reference of paratii-contracts i got some errors such as IPFS timeouts and failure when deploying contracts. It might be a trouble in my environment, i'll take a look.

if you have any specific problems, could you signal them here? Paratii-Video/paratii-portal#656

Yes, for sure. I'll try to run paratii-js tests again and investigate the problem.

@jellegerbrandy I've noticed two problems when running paratii-js tests:

1. I couldn't use parity 1.11.1. After downgrading to 1.9.0 a lot of errors has disappeared.
2. ParatiiIPFSLocal tests doesn't work well
   2.1) it('should allow for file upload', ... ) expects a different multihash of the file stored.
   2.2) it('should add a directory to IPFS',...) getting Timeout error.

@jellegerbrandy To fix the tests of paratii-js regarding Solidity 0.4.23/24, i had to add these parameters in the section params of chain.json:

   "eip140Transition": 0,
   "eip211Transition": 0,
   "eip214Transition": 0,
   "eip658Transition": 0

It enables byzantium features.
Parity: 1.10.0
