## 0x Contribution Guide
|
||||
|
||||
We welcome contributions from anyone on the internet and are grateful for even the smallest contributions. This document will help get you setup to start contributing back to 0x.
|
||||
Thank you for your interest in contributing to 0x protocol! We welcome contributions from anyone on the internet, and are grateful for even the smallest of fixes!
|
||||
|
||||
### Getting started
|
||||
### How to contribute
|
||||
|
||||
1. Fork `0xproject/0x-monorepo`
|
||||
2. Clone your fork
|
||||
3. Follow the [installation & build steps](https://github.com/0xProject/0x-monorepo#install-dependencies) in the repo's top-level README.
|
||||
4. Setup the recommended [Development Tooling](#development-tooling).
|
||||
5. Open a PR with the `[WIP]` flag against the `development` branch and describe the change you are intending to undertake in the PR description. (see [our branch naming conventions](#branch-structure))
|
||||
If you'd like to contribute to 0x protocol, please fork the repo, fix, commit and send a pull request against the `development` branch for the maintainers to review and merge into the main code base. If you wish to submit more complex changes though, please check with a core dev first on [our RocketChat #dev channel](http://chat.0xproject.com) to ensure those changes are in-line with the general philosophy of the project and/or to get some early feedback which can make both your efforts easier as well as our review and merge procedures quick and simple.
|
||||
|
||||
Before removing the `[WIP]` tag and submitting the PR for review, make sure:
|
||||
We encourage a “PR early” approach so create the PR as early as possible even without the fix/feature ready, so that devs and other contributors know you have picked up the issue. These early PRs should indicate an 'in progress' status by adding the '[WIP]' prefix to the PR title. Please make sure your contributions adhere to our coding guidelines:
|
||||
|
||||
* It passes our linter checks (`yarn lint`)
|
||||
* It is properly formatted with Prettier (`yarn prettier`)
|
||||
* It passes our continuous integration tests (See: [Enabling code coverage checks on your fork](#enabling-code-coverage-checks-on-your-fork) for instructions on getting the `submit-coverage` test to pass on forks)
|
||||
* You've created/updated the corresponding [CHANGELOG](#CHANGELOGs) entries.
|
||||
* Your changes have sufficient test coverage (e.g regression tests have been added for bug fixes)
|
||||
* Pull requests adding features or refactoring should be opened against the `development` branch
|
||||
* Pull requests fixing bugs in the latest release version should be opened again the `master` branch
|
||||
* Write [good commit messages](https://chris.beams.io/posts/git-commit/)
|
||||
|
||||
### Branch structure
|
||||
### Code quality
|
||||
|
||||
We have two main branches:
|
||||
Because 0x.js is used by multiple relayers in production and their businesses depend on it, we strive for exceptional code quality. Please follow the existing code standards and conventions. `tslint` and `prettier` (described below) will help you.
|
||||
|
||||
* `master` represents the most recently released (published on npm) version of the codebase.
|
||||
* `development` represents the current development state of the codebase.
|
||||
If you're adding functionality, please also add tests and make sure they pass. We have an automatic coverage reporting tool, so we'll see it if they are missing ;)
|
||||
If you're adding a new public function/member, make sure you document it with Java doc-style comments. We use typedoc to generate [awesome documentation](https://0xproject.com/docs/0xjs) from the comments within our source code.
|
||||
|
||||
ALL PRs should be opened against `development`.
|
||||
If the sub-package you are modifying has a `CHANGELOG.md` file, make sure to add an entry in it for the change made to the package. For published packages, only changes that modify the public interface or behavior of the package need a CHANGELOG entry.
|
||||
|
||||
Branch names should be prefixed with `fix`, `feature` or `refactor`.
|
||||
### Styleguide
|
||||
|
||||
* e.g `fix/broken-wiki-link`
|
||||
* If the PR only edits a single package, add it's name too
|
||||
* e.g `fix/website/broken-wiki-link`
|
||||
We use [TSLint](https://palantir.github.io/tslint/) with [custom configs](https://github.com/0xProject/0x-monorepo/tree/development/packages/tslint-config) to keep our code style consistent.
|
||||
|
||||
### CHANGELOGs
|
||||
To lint your code just run: `yarn lint`
|
||||
|
||||
At 0x we use [Semantic Versioning](http://semver.org/) for all our published packages. If a change you make corresponds to a semver bump, you must modify the package's `CHANGELOG.json` file accordingly.
|
||||
|
||||
Each CHANGELOG entry that corresponds to a published package will have a `timestamp`. If no entry exists without a `timestamp`, you must first create a new one:
|
||||
|
||||
```
|
||||
{
|
||||
"version": "1.0.1", <- The updated package version
|
||||
"changes": [
|
||||
{
|
||||
"note": "", <- Describe your change
|
||||
"PR": 100 <- Your PR number
|
||||
}
|
||||
]
|
||||
},
|
||||
```
|
||||
|
||||
If an entry without a `timestamp` already exists, this means other changes have been introduced by other collaborators since the last publish. Add your changes to the list of notes and adjust the version if your PR introduces a greater semver change (i.e current changes required a patch bump, but your changes require a major version bump).
|
||||
|
||||
### Development Tooling
|
||||
|
||||
We strongly recommend you use the [VSCode](https://code.visualstudio.com/) text editor since most of our code is written in Typescript and it offers amazing support for the language.
|
||||
|
||||
#### Linter
|
||||
|
||||
We use [TSLint](https://palantir.github.io/tslint/) with [custom configs](https://github.com/0xProject/0x-monorepo/tree/development/packages/tslint-config) to keep our code-style consistent.
|
||||
|
||||
Use `yarn:lint` to lint the entire monorepo, and `PKG={PACKAGE_NAME} yarn lint` to lint a specific package.
|
||||

If you want to change a rule, or add a custom rule, please make these changes to our [tslint-config](https://github.com/0xProject/0x-monorepo/tree/development/packages/tslint-config) package. All other packages have it as a dependency.
|
||||
|
||||
Integrate it into your text editor:
|
||||
|
||||
* VSCode: [vscode-tslint](https://marketplace.visualstudio.com/items?itemName=eg2.tslint)
|
||||
* Atom: [linter-tslint](https://atom.io/packages/linter-tslint)
|
||||
|
||||
#### Auto-formatter
|
||||
|
||||
We use [Prettier](https://prettier.io/) to auto-format our code. Be sure to either add a [text editor integration](https://prettier.io/docs/en/editors.html) or a [pre-commit hook](https://prettier.io/docs/en/precommit.html) to properly format your code changes.
|
||||
We also use [Prettier](https://prettier.io/) to auto-format our code. Be sure to either add a [text editor integration](https://prettier.io/docs/en/editors.html) or a [pre-commit hook](https://prettier.io/docs/en/precommit.html) to properly format your code changes.
|
||||
|
||||
If using the Atom text editor, we recommend you install the following packages:
|
||||
|
||||
* VSCode: [prettier-vscode](https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode)
|
||||
* Atom: [prettier-atom](https://atom.io/packages/prettier-atom)
|
||||
* [atom-typescript](https://atom.io/packages/atom-typescript)
|
||||
* [linter-tslint](https://atom.io/packages/linter-tslint)
|
||||
* [prettier-atom](https://atom.io/packages/prettier-atom)
|
||||
* [language-ethereum](https://atom.io/packages/language-ethereum)
|
||||
|
||||
## Unenforced coding conventions
|
||||
Our CI will also run TSLint and Prettier as a part of the test run when you submit your PR. Make sure that the CI tests pass for your contribution.
|
||||
|
||||
A few of our coding conventions are not yet enforced by the linter/auto-formatter. Be careful to follow these conventions in your PR's.
|
||||
### Branch structure & versioning
|
||||
|
||||
1. Unused anonymous function parameters should be named with an underscore + number (e.g \_1, \_2, etc...)
|
||||
1. There should be a new-line between methods in a class and between test cases.
|
||||
1. If a string literal has the same value in two or more places, it should be a single constant referenced in both places.
|
||||
1. Do not import from a project's `index.ts` (e.g import { Token } from '../src';). Always import from the source file itself.
|
||||
1. Generic error variables should be named `err` instead of `e` or `error`.
|
||||
1. If you _must_ cast a variable to any - try to type it back as fast as possible. (e.g., `const cw = ((zeroEx as any)._contractWrappers as ContractWrappers);`). This ensures subsequent code is type-safe.
|
||||
1. Our enum conventions coincide with the recommended Typescript conventions, using capitalized keys, and all-caps snake-case values. Eg `GetStats = 'GET_STATS'`
|
||||
1. All public, exported methods/functions/classes must have associated Javadoc-style comments.
|
||||
We use [semantic versioning](http://semver.org/), but before a package reaches v1.0.0 all breaking changes as well as new features will be minor version bumps.
|
||||
|
||||
### Fix `submit-coverage` CI failure
|
||||
We have two main branches: `master` and `development`.
|
||||
|
||||
If you simply fork the repo and then create a PR from it, your PR will fail the `submit-coverage` check on CI. This is because the 0x CircleCI configuration sets the `COVERALLS_REPO_TOKEN` environment variable to the token for `0xProject/0x-monorepo`, but when running the check against your fork the token needs to match your repo's name `your-username/0x-monorepo`.
|
||||
`master` represents the most recent released (published on npm) version.
|
||||
|
||||
To facilitate this check, after creating your fork, but before creating the branch for your PR, do the following:
|
||||
|
||||
1. Log in to [coveralls.io](https://coveralls.io/), go to `Add Repos`, and enable your fork. Then go to the settings for that repo, and copy the `Repo Token` identifier.
|
||||
2. Log in to [CircleCI](https://circleci.com/login), go to `Add Projects`, click the `Set Up Project` button corresponding to your fork, and then click `Start Building`. (Aside from step 3 below, no actual set up is needed, since it will use the `.circleci/config.yml` file in 0x-monorepo, so you can ignore all of the instruction/explanation given on the page with the `Start Building` button.)
|
||||
3. In CircleCI, configure your project to add an environment variable, with name `COVERALLS_REPO_TOKEN`, and for the value paste in the `Repo Token` you copied in step 1.
|
||||
|
||||
Now, when you push to your branch, CircleCI will automatically run all of the checks in your own instance, and the coverage check will work since it has the proper `Repo Token`, and the PR will magically refer to your own checks rather than running them in the 0x CircleCI instance.
|
||||
`development` represents the development state and is a default branch to which you will submit a PR. We use this structure so that we can push hotfixes to the currently released version without needing to publish all the changes made towards the next release. If a hotfix is implemented on `master`, it is back-ported to `development`.

# Contracts testing options
|
||||
|
||||
## Revert stack traces
|
||||
|
||||
If you want to see helpful stack traces (incl. line number, code snippet) for smart contract reverts, run the tests with:
|
||||
|
||||
```
|
||||
yarn test:trace
|
||||
```
|
||||
|
||||
**Note:** This currently slows down the test runs and is therefore not enabled by default.
|
||||
|
||||
## Backing Ethereum node
|
||||
|
||||
By default, our tests run against an in-process [Ganache](https://github.com/trufflesuite/ganache-core) instance. In order to run the tests against [Geth](https://github.com/ethereum/go-ethereum), first follow the instructions in the README for the devnet package to start the devnet Geth node. Then run:
|
||||
|
||||
```bash
|
||||
TEST_PROVIDER=geth yarn test
|
||||
```
|
||||
|
||||
## Code coverage
|
||||
|
||||
In order to see the Solidity code coverage output generated by `@0x/sol-cov`, run:
|
||||
|
||||
```
|
||||
yarn test:coverage
|
||||
```
|
||||
|
||||
## Gas profiler
|
||||
|
||||
In order to profile the gas costs for a specific smart contract call/transaction, you can run the tests in `profiler` mode.
|
||||
|
||||
**Note:** Traces emitted by ganache have incorrect gas costs so we recommend using Geth for profiling.
|
||||
|
||||
```
|
||||
TEST_PROVIDER=geth yarn test:profiler
|
||||
```
|
||||
|
||||
You'll see a warning that you need to explicitly enable and disable the profiler before and after the block of code you want to profile.
|
||||
|
||||
```typescript
|
||||
import { profiler } from './utils/profiler';
|
||||
profiler.start();
|
||||
// Some call to a smart contract
|
||||
profiler.stop();
|
||||
```
|
||||
|
||||
Without explicitly starting and stopping the profiler, the profiler output will be too busy, and therefore unusable.

## Contract examples
|
||||
|
||||
Example smart contracts that interact with 0x protocol.
|
||||
|
||||
## Usage
|
||||
|
||||
Contracts can be found in the [contracts](./contracts) directory.
|
||||
This package contains example implementations of contracts that interact with the protocol but are _not_ intended for use in production. Examples include [filter](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#filter-contracts) contracts, a [Wallet](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#wallet) contract, and a [Validator](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md#validator) contract, among others.
|
||||
|
||||
## Contributing
|
||||
|
||||
We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
|
||||
|
||||
For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein.
|
||||
|
||||
Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.

## Contract extensions
|
||||
|
||||
Smart contracts that implement extensions for the 0x protocol.
|
||||
|
||||
## Usage
|
||||
|
||||
Contract extensions of the protocol can be found in the [contracts](./contracts) directory. This directory contains contracts that interact with the 2.0.0 contracts and will be used in production, such as the [Forwarder](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/forwarder-specification.md) contract.
|
||||
|
||||
## Bug bounty
|
||||
|
||||
A bug bounty for the 2.0.0 contracts is ongoing! Instructions can be found [here](https://0xproject.com/wiki#Bug-Bounty).
|
||||
|
||||
## Contributing
|
||||
|
||||
We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
|
||||
|
||||
For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein.
|
||||
|
||||
Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
|
||||
|
||||

|
||||
Or continuously rebuild on change:
|
||||
|
||||
```bash
|
||||
PKG=@0x/contracts-extensions yarn watch
|
||||
```
|
||||
|
||||

## Contract interfaces
|
||||
|
||||
Smart contract interfaces of the 0x protocol.
|
||||
|
||||
## Usage
|
||||
|
||||
Contracts that make up and interact with version 2.0.0 of the protocol can be found in the [contracts](./contracts) directory. The contents of this directory are broken down into the following subdirectories:
|
||||
|
||||
* [protocol](./contracts/protocol)
|
||||
* This directory contains the contract interfaces that make up version 2.0.0. A full specification can be found [here](https://github.com/0xProject/0x-protocol-specification/blob/master/v2/v2-specification.md).
|
||||
|
||||
## Bug bounty
|
||||
|
||||
A bug bounty for the 2.0.0 contracts is ongoing! Instructions can be found [here](https://0xproject.com/wiki#Bug-Bounty).
|
||||
|
||||
## Contributing
|
||||
|
||||
We strongly recommend that the community help us make improvements and determine the future direction of the protocol. To report bugs within this package, please create an issue in this repository.
|
||||
|
||||
For proposals regarding the 0x protocol's smart contract architecture, message format, or additional functionality, go to the [0x Improvement Proposals (ZEIPs)](https://github.com/0xProject/ZEIPs) repository and follow the contribution guidelines provided therein.
|
||||
|
||||
Please read our [contribution guidelines](../../CONTRIBUTING.md) before getting started.
