# Contributing Guide
Thank you for contributing to this project.
This repository follows a release-first workflow: `main` is the default public branch, while releases are prepared through `release/*` branches.
---
## Branch Model
- `main`: stable release branch and default branch
- `dev`: day-to-day integration branch for maintainers
- `release/*`: release preparation branches for maintainers
- Recommended branch names for external contributors:
- `fix/*`: bug fixes
- `feature/*`: new features or enhancements
Maintainer release flow:
```text
feature/* / fix/* -> dev -> release/* -> main -> tag(vX.Y.Z)
```
---
## How External Contributors Should Open Pull Requests
Whether your branch is `fix/*` or `feature/*`, external contributors should **open pull requests directly against `main`**.
Reasons:
- `main` is the default branch, so the PR entry point is clearer
- merged contributions are immediately visible on the default branch
- maintainers can handle downstream sync and release preparation in one place
Recommended flow:
1. Fork this repository
2. Create a branch in your fork (`fix/*` or `feature/*` is recommended)
3. Make your changes and perform basic self-checks
4. Push the branch to your fork
5. Open a pull request against the `main` branch of this repository
---
## Pull Request Requirements
Please keep each pull request focused, reviewable, and easy to validate.
Recommended expectations:
- one pull request should address one logical change
- use a clear title that explains the purpose
- include the following in the description:
- background and problem statement
- key changes
- impact scope
- validation method
- include screenshots or recordings for UI changes when helpful
- explicitly mention risk and rollback notes for compatibility, data, or build-chain changes
---
## Merge Strategy for Maintainers
Pull requests merged into `main` should generally use **Squash and merge**.
Reasons:
- keeps `main` history clean and linear
- maps each PR to a single commit on `main`
- reduces release, audit, and rollback complexity
---
## Maintainer Sync Rules
Because external pull requests are merged directly into `main`, maintainers must sync `main` back to development and release branches to avoid branch drift.
### 1. Sync `main` -> `dev` (required)
This repository provides automatic sync via GitHub Actions workflow:
- `.github/workflows/sync-main-to-dev.yml`
- Trigger: every push to `main`
- Behavior: create/reuse a PR from `main` to `dev`; if mergeable, it tries to enable auto-merge
- Prerequisite: in `Settings -> Actions -> General -> Workflow permissions`, enable `Allow GitHub Actions to create and approve pull requests`; otherwise the workflow will skip PR creation and only emit a warning summary
Manual fallback (when conflicts or automation is unavailable):
```bash
git checkout dev
git pull
git merge main
git push
```
### 2. Create `release/*` from `dev`
Before a release, create a release branch from `dev`, for example:
```bash
git checkout dev
git pull
git checkout -b release/v0.6.0
git push -u origin release/v0.6.0
```
### 3. Release from `release/*` back to `main`
When release preparation is complete, merge the release branch back into `main` and create a tag:
```bash
git checkout main
git pull
git merge release/v0.6.0
git push
git tag v0.6.0
git push origin v0.6.0
```
### 4. Sync `main` back to `dev` after release
After the release, the same automation still applies. If needed, you can run the workflow manually (`workflow_dispatch`) or execute the fallback commands:
```bash
git checkout dev
git pull
git merge main
git push
```
---
## Commit Message Recommendation
Keep commit messages clear and easy to audit.
Recommended format:
```text
emoji type(scope): concise description
```
Examples:
```text
🔧 fix(ci): fix DuckDB driver toolchain on Windows AMD64
✨ feat(redis): add Stream data browsing support
♻️ refactor(datagrid): optimize large-table horizontal scrolling and rendering
```
---
## Additional Notes
- Please include validation results for documentation, build-chain, or driver compatibility changes
- For larger changes, opening an issue or draft PR first is recommended
- Maintainers may ask contributors to narrow the scope if the change conflicts with the current project direction
Thank you for contributing.
