etherollapp's Introduction

EtherollApp

Provably fair dice game running on the Ethereum blockchain. Built with Python, Kivy and love.

Closed down

The upstream project/smart-contract closed down. https://www.reddit.com/r/etheroll/comments/peeekh/etheroll_is_closing_down/

Install & Usage

EtherollApp is available on PyPI. Therefore it can be installed via pip.

pip3 install --user EtherollApp

Once installed, it should be available in your PATH and can be ran from the command line.

etherollapp

Develop & Contribute

If you want to experiment with the project or contribute, you can clone it and install dependencies.

make

Later run the code on desktop via the run target.

make run

Unit tests are also available.

make test
make uitest

On Android you can build, deploy and run using Buildozer.

buildozer android debug deploy run logcat

And debug with logcat.

buildozer android adb -- logcat

etherollapp's Issues

Refactoring files split

The project is getting bigger so we should split in different files rather keeping it all on etheroll.{py.kv}

Remember selected account

Every time we open the app, we need to select the account for playing.
This should be kept in a user settings instead and restored when opening the application.

Per account bet history

It should be possible to see bet history for a given account.
Clicking the history would display a detailed view with:

bet size
result win/lose
reward
chances/roll under
actual result
tx hashes (both bet and callback) #49

This probably needs to be split in separated tasks.

Switch testnet/mainnet from UI

Make it possible to choose the network from the UI.

Caching Travis Linux Docker build

Now that the project runs on TravisCI (#18 and #19), it would be great to cache Docker images so docker build doesn't always start from scratch.

pyetheroll.py refactoring

pyetheroll.py is currently mixing a lot of draft/trial-error code.
It needs to be refactored/cleaned

Account update

Make it possible to update account password.

Configurable gas price

Make it possible for the user to configure gas price in some settings panel.

Setup continuous integration

Setup continuous integration testing using something like Travis.
It should at minimum run tox for testing the library. It would be better if it can also run UI testing.

https://stackoverflow.com/questions/35192400/travis-vs-circleci-vs-jenkins
https://stackshare.io/stackups/circleci-vs-jenkins-vs-travis-ci

Rolls details when clicking the item

When clicking a roll/result item we should print some details such as:

bet size
clickable (Etherscan) tx hashes (both bet and callback)
...

assertion PyBytes_Check failed

Getting run time error when compiling the project under Gentoo. In the Ubuntu 16.04 VM it doesn't happen.
See upstream for more details: kivy/python-for-android#1247

Automated UI testing

Currently three candidates:

KeyWeeUsr/KivyUnitTest
eviltnan/kivy-autotesting-example
Kivy recorder kivy.modules.recorder and kivy.input.recorder
tito/telenium

All are pretty much experimental. I've worked with KivyUnitTest before and it was OK even though far from perfect.

Show smart contract from UI

Make it possible to display the smart contract address somewhere.

Dockerize Android APK compile

Just like we compiled the project for Linux via Docker in #19 we could do the same for Android/Buildozer.

Select wallet from list

Make it possible to select wallet out of an existing list, probing from file system.

This is a known buildozer issue kivy/buildozer#312

Decode event log from given transaction log

Given a transaction hash, make it possible to fetch event log and decode it using associated ABI

Python3 + greenlet install issue

Can't build greenlet (on both Gentoo and Ubuntu).

Upstream issue kivy/python-for-android#1251

Auto fetching of contract ABI

From a given contract address, make it possible to fetch and cache the ABI.

Integrate with Sentry

Hook to Sentry to collect errors/crashes.
If possible it should be only enabled for Android release versions, hence not for desktop and not in Android debug.

Setup usage statistics

Setup a way to track application usage.
Take a look at Firebase https://firebase.google.com/docs/analytics/android/start/

OSError: [Errno 2] No such file or directory: 'build'

Recipes that requires hostpython3crystax fail with non existing build directory.
kivy/python-for-android#1154 (bug) and kivy/python-for-android#1249 (pull request).

Porting to Android

See if it compiles on Android, otherwise create subtask for porting thirdparty packages to python-for-android.

Known issues:

Deployment IOError/FileNotFoundError: #26
assertion PyBytes_Check failed: #27
~~setuptools Python3: kivy/python-for-android#1248~~
OSError: [Errno 2] No such file or directory: 'build': #28
~~Gevent compilation issues: #29~~
~~FileNotFoundError lib crypto on Android: #30~~

iOS/iPhone support

Port the application to iOS.

Since I'm running Linux only, this would never happen unless somebody does it, or if I can cross compile it on Linux.
Here are some useful resources:

Handle wrong wallet password error

This is a follow up for #7. Currently if the password is wrong, the app will crash.
We need to:

handle wrong password gracefully
make it possible to try again setting/caching the password

UI testing rolling screen sliders

Verify the rolling screen bet size & chances sliders work as expected.

check bet size <-> input coupling
check chances <-> input coupling, refs #46
labels coupling (roll under, wager & profit)
clicking roll places the bet with expected parameters

Add Android compilation to TravisCI

Just like we've integrated Linux unit tests from Docker to Travis #18, we should do the same for Android APK Buildozer building.

Android splash screen and icon

buildozer.spec

presplash.filename = docs/images/icon.png
icon.filename = docs/images/icon.png

Since Etherscan was not ready for topic0 and topic3 filtering at the same time, we had to put a workaround that was filtering topic3 with Etherscan and topic0 in Python.
This was resolved recently, see https://www.reddit.com/r/etherscan/comments/8cg7xh/etherscan_event_log_filter/
So we now need to update get_log_result_events() to use Etherscan only topics filtering.

Place a bet on the testnet

Deploy the contract on the testnet, try to place a bet and document the instructions

how to deploy on the testnet
including the mining on testnet to get enough for deployment
updated library and code example for placing the bet (playerRollDice())

Lazy screen loading

Currently all the screen objects get initialized at application startup. This is not good because it slows down the application and eats the ram. We should setup some lazy screen loading so they only get initialized when needed.

Quick account actions

Make it possible to perform quick account actions via list bottom sheet.
Clicking on the account should pop a list bottom sheet with the following actions:

copy Ethereum address to clipboard
switch account
show QRCode #44

Account creation

Make it possible to create a wallet from the app.

Implement new UI design

https://etheroll.wordpress.com/2017/12/11/development-update-updated-branding-ui-ux-teaser/

Show account QR Code

Receiving ethers via QR Code is easier than copy pasting public address.

Ask for wallet password once

Only ask the wallet password and forget it only when the application is closed.

basic unit testing

Once we start having stable enough tooling functions, it should be unit tested to avoid regressions.
At the same time introduce tox with at minimum pep8 and flake8.
