From 036669d89c250e088b535a11352bc189c3eec26d Mon Sep 17 00:00:00 2001 From: zhao vistart Date: Sun, 7 Jun 2026 00:16:26 +0800 Subject: [PATCH 01/17] feat(postgres): add pg_partman partition support Add PostgreSQL partition and pg_partman support with dialect, expression, protocol, mixin, provider, and test updates. Also apply ruff formatting/lint cleanup across the current change set and add low-risk backend signature annotations.

Branching and Release Strategy + +### Branch Structure + +**Main Branch** (`main`): + +- **Purpose**: Current production-ready state +- **Protection**: Required reviews, all CI checks must pass +- **Merge Strategy**: Squash and merge for features, rebase for hotfixes +- **Source of Truth**: Always represents the latest acceptable release state +- **Continuous Integration**: Must pass all tests at all times + +**Pre-release Version Branches** (`release/vX.Y.Z[.devN|aN|bN|rcN]`): + +- **Purpose**: Staging ground for specific version development +- **Creation**: Branched from `main` when starting new version development +- **Naming**: Uses full version number including pre-release suffix with `v` prefix +- **Lifecycle**: From dev phase through to final release +- **Examples**: + - `release/v1.2.0.dev1` - Development branch + - `release/v1.2.0` - Unified branch for alpha/beta/rc/final (reused across phases) + +**Development Branches** (from pre-release branch): + +- **Feature Branches**: `feature/{ticket-number}-{description}` or `feature/{description}` +- **Bug Fix Branches**: `fix/{ticket-number}-{description}` or `bugfix/{description}` +- **Documentation Branches**: `docs/{description}` +- **Test Branches**: `test/{description}` + +**Hotfix Branches** (`hotfix/{ticket-number}-{description}` or `hotfix/{version}`): + +- **Purpose**: Critical fixes to production releases +- **Source**: Branched from `main` or production tag +- **Target**: Merge back to `main` and active `release/` branches +- **Fast-tracked**: Emergency review and merge process + +### Feature Branch Management + +#### Creating Feature Branches + +**Best Practices**: + +- **Branch early, merge often**: Create feature branch as soon as work begins +- **Keep branches focused**: One feature/fix per branch +- **Small, incremental changes**: Easier to review and less conflict-prone +- **Regular synchronization**: Sync with pre-release branch frequently +- **Push early for CI feedback**: Get automated test results quickly + +**Creation Process**: + +```bash +# 1. Ensure pre-release branch is up to date +git checkout release/v1.2.0.dev1 +git pull origin release/v1.2.0.dev1 + +# 2. Create focused feature branch +git checkout -b feature/ar-123-recursive-cte + +# 3.

Push early for visibility and CI feedback +git push origin feature/ar-123-recursive-cte + +# 5. Create draft PR immediately for CI validation +# - Navigate to GitHub +# - Create draft PR to release/v1.2.0.dev1 +# - CI runs automatically +# - Monitor CI results while developing +``` + +**CI-Driven Development**: + +```bash +# Check CI status after push +# GitHub UI shows: ✓ or ✗ for each check + +# If CI fails: +# 1. Review failure logs in GitHub Actions +# 2. Fix locally +git add . +git commit -m "fix: address test failure in CI" +git push # Triggers new CI run + +# 3.

Mark issue as "Won't Fix" or "Postponed" in issue tracker +``` + +**Preventing Fragment Conflicts**: + +- Fragments are deleted along with abandoned branches +- No fragment enters CHANGELOG.md until release +- Only merged features contribute to release notes + +**Communication**: + +- Notify team via issue tracker +- Update project board/sprint planning +- Document decision for future reference + +#### Long-Running Feature Branches + +**Definition**: Feature branches that span multiple weeks or cross version boundaries + +**Problems**: + +- Accumulate merge conflicts +- Diverge significantly from pre-release branch +- Difficult to review when PR is finally created +- May block other work + +**Strategies to Avoid**: + +**1. Break Down Large Features**: + +```bash +# Instead of one large branch: +feature/ar-123-full-graphql-support # BAD: too large + +# Break into smaller, mergeable pieces: +feature/ar-123-1-graphql-parser # Part 1: Parser +feature/ar-123-2-graphql-resolver # Part 2: Resolver +feature/ar-123-3-graphql-mutations # Part 3: Mutations +``` + +**2.

Regular Synchronization**: + +```bash +# Set calendar reminder to sync every 3 days +git fetch origin +git rebase origin/release/v1.2.0.dev1 +``` + +**4. Progressive PRs**: + +```bash +# Create draft PR early for visibility and feedback +# Update PR with each commit +# Request incremental reviews +``` + +**If Feature Crosses Version Boundary**: + +```bash +# Scenario: Working on feature for 1.2.0, but 1.2.0 is released +# and work continues on 1.3.0 + +# Option A: Rebase onto new version's pre-release branch +git checkout feature/ar-123-recursive-cte +git rebase --onto release/v1.3.0.dev1 release/v1.2.0.dev1 + +# Option B: Complete for 1.2.1 as bug fix if critical +# Convert to hotfix branch + +# Option C: Postpone to next minor version +# Continue on 1.3.0 pre-release branch +``` + +#### Multiple Developers on Same Feature + +**Scenario**: Large feature requires multiple developers + +**Recommended Approach**: + +```bash +# 1.
