First, thank you for your interest in contributing to this project! Before you pick up your first issue and start changing code, please:
- Review all documentation for the module you're interested in.
- Look through the issues for this repo for relevant discussions.
- If you have questions about an issue, post a comment in the issue.
- If you want to submit changes that aren't covered by an issue, file a new one with your proposal, outlining what problem you found/feature you want to implement, and how you intend to implement a solution.
For best results, before submitting a PR, make sure:
- It has met all acceptance criteria for the issue.
- It addresses only the one issue and does not make other, irrelevant changes.
- Your code conforms to our coding style guide.
- You have adequate test coverage (this should be indicated by CI results anyway).
- If you like, check out current PRs to see how others do it.
Special Note: If editing README.md, please conform to the standard readme specification.
Active development of go-fil-markets
occurs on the master
branch. All PRs should be made to the master
branch, which is the default branch on Github.
Before a PR can be merged to master
, it must:
- Pass continuous integration.
- Be rebased and up to date with the
master
branch - Be approved by at least two maintainers
When merging normal PRs to master
, always use squash and merge to maintain a linear commit history.
When creating a new full release, branch off master with a branch named release/version-number, where version-number is the ultimate tag you intend to create.
Continue to develop on master and merge commits to your release branch as neccesary till the release is ready.
When the release is ready, tag it, then merge the branch back into master so that it is part of the version history of master. Delete the release branch.
Hot-fixes operate just like release branches, except they are branched off an existing tag and should be named hotfix/version-number. When ready, they receive their own tag and then are merged back to master, then deleted.
For external reference, his git flow and release process is essentially the OneFlow git workflow
Following the release of Filecoin Mainnet, this library will following a semantic versioning scheme for tagged releases.
- All new code should be accompanied by unit tests. Prefer focused unit tests to integration tests for thorough validation of behaviour. Existing code is not necessarily a good model, here.
- Integration tests should test integration, not comprehensive functionality
- Tests should be placed in a separate package named
$PACKAGE_test
. For example, a test of thechain
package should live in a package namedchain_test
. In limited situations, exceptions may be made for some "white box" tests placed in the same package as the code it tests.
We use the following import ordering.
import (
[stdlib packages, alpha-sorted]
<single, empty line>
[external packages]
<single, empty line>
[other-filecoin-project packages]
<single, empty line>
[go-fil-markets packages]
)
Where a package name does not match its directory name, an explicit alias is expected (goimports
will add this for you).
Example:
import (
"context"
"testing"
cmds "github.com/ipfs/go-ipfs-cmds"
cid "github.com/ipfs/go-cid"
ipld "github.com/ipfs/go-ipld-format"
"github.com/stretchr/testify/assert"
datatransfer "github.com/filecoin-project/go-data-transfer/v2"
"github.com/filecoin-project/go-fil-markets/filestore/file"
)
You can run script/fiximports
to put all your code in the desired format
Comments are a communication to other developers (including your future self) to help them understand and maintain code. Good comments describe the intent of the code, without repeating the procedures directly.
- A
TODO:
comment describes a change that is desired but could not be immediately implemented. It must include a reference to a GitHub issue outlining whatever prevents the thing being done now (which could just be a matter of priority). - A
NOTE:
comment indicates an aside, some background info, or ideas for future improvement, rather than the intent of the current code. It's often fine to document such ideas alongside the code rather than an issue (at the loss of a space for discussion). FIXME
,HACK
,XXX
and similar tags indicating that some code is to be avoided in favour ofTODO
,NOTE
or some straight prose.
