dbflux-release

name	dbflux-release
description	Create versioned releases for DBFlux with automated version bumping across all package manifests. Trigger: When user asks to create a release, bump version, tag a release, or prepare a new version.
license	Apache-2.0
metadata	{"version":"1.0"}

When to Use

• User requests a release or version bump
• User asks to tag a new version
• User mentions updating CHANGELOG or version numbers
• Preparing a stable or dev release

Versioning Rules

main branch (stable)

• Format: vX.Y.Z
• X (major): Breaking changes or significant milestones
  • While X=0: Y acts as major version
• Y (minor): Important features or changes
• Z (patch): Bug fixes and small improvements

dev branch (unstable)

• Format: vX.Y.Z-dev.W
• X.Y.Z: Next planned version from main
• W: Dev iteration counter (increments with each dev release)
• X.Y.Z remain stable until merged to main

Release Workflow

1. Version Decision

User priority: Always prefer user-specified version over automated suggestions.

If user doesn't specify:

• Check current branch (main vs dev)
• Get last tag: git describe --tags --abbrev=0
• Compare changes: git log <last-tag>..HEAD --oneline
• Analyze changes for breaking/feature/fix patterns
• Suggest appropriate version bump

2. Pre-Release Validation

Run quality checks before committing version bump:

cargo build
cargo check --workspace
cargo clippy --workspace -- -D warnings
cargo fmt --all -- --check
cargo test --workspace

All checks must pass. If any fail, abort the release and report errors.

3. Version Bump Files

Update version in ALL these files:

File	Format	Notes
Cargo.toml (workspace)	version = "X.Y.Z"	Root workspace version
crates/*/Cargo.toml	version = "X.Y.Z"	All crate versions
flake.nix	version = "X.Y.Z";	Nix package version
resources/windows/installer.iss	Version="X.Y.Z"	Windows installer
scripts/PKGBUILD	pkgver=X.Y.Z	Arch Linux package
CHANGELOG.md	Add section ## [X.Y.Z] - YYYY-MM-DD	Release notes

Strip version prefix: Files use X.Y.Z not vX.Y.Z (tag has the v prefix).

4. CHANGELOG Update

Compare commits since last tag:

git log <last-tag>..HEAD --pretty=format:"- %s" --reverse

Group changes by category:

• Breaking Changes: API changes, removed features
• Features: New functionality
• Fixes: Bug fixes
• Improvements: Performance, UX enhancements
• Chores: Dependencies, refactoring

Add new section at top of CHANGELOG.md:

## [X.Y.Z] - YYYY-MM-DD

### Breaking Changes
- ...

### Features
- ...

### Fixes
- ...

5. Commit and Tag

# Stage all version changes
git add Cargo.toml crates/*/Cargo.toml flake.nix packaging/ CHANGELOG.md

# Commit with version bump message
git commit -m "chore: bump version to vX.Y.Z"

# Create annotated tag
git tag -a vX.Y.Z -m "Release vX.Y.Z"

Commands

# Check last tag
git describe --tags --abbrev=0

# Compare with last tag
git log $(git describe --tags --abbrev=0)..HEAD --oneline

# Pre-release checks
cargo build && \
cargo check --workspace && \
cargo clippy --workspace -- -D warnings && \
cargo fmt --all -- --check && \
cargo test --workspace

# Update all workspace crate versions
find crates -name Cargo.toml -exec sed -i 's/^version = ".*"/version = "X.Y.Z"/' {} \;

# Stage version files
git add Cargo.toml crates/*/Cargo.toml flake.nix packaging/ CHANGELOG.md

# Create release
git commit -m "chore: bump version to vX.Y.Z"
git tag -a vX.Y.Z -m "vX.Y.Z"

Decision Trees

Branch Detection

Current branch = main?
├─ Yes → Stable release (vX.Y.Z)
└─ No  → Check if dev branch
          ├─ Yes → Dev release (vX.Y.Z-dev.W)
          └─ No  → Warn: releases only from main/dev

Version Increment (main)

Breaking changes found?
├─ Yes → Bump major (or minor if X=0)
└─ No  → New features found?
          ├─ Yes → Bump minor
          └─ No  → Bump patch

Version Increment (dev)

Last tag format = vX.Y.Z-dev.W?
├─ Yes → Increment W
└─ No  → Create vX.Y.Z-dev.1 (X.Y.Z = next main version)

Critical Patterns

1. Version String Handling

// In files: NO 'v' prefix
version = "0.2.1"

// In git tags: YES 'v' prefix
git tag -a v0.2.1

2. Workspace Version Sync

All crates must have identical versions. Use workspace-level version or explicit sync.

# Root Cargo.toml
[workspace.package]
version = "0.2.1"

# Crate Cargo.toml
[package]
version.workspace = true

If not using workspace inheritance, update each crates/*/Cargo.toml individually.

3. Pre-Release Validation is Non-Negotiable

Never commit version bumps if checks fail. GitHub Actions will fail anyway.

4. User Version Priority

User specifies version → Use it (validate format only)
User says "decide" → Analyze commits and suggest
User silent → Ask for version or permission to decide

5. CHANGELOG Commit Analysis

Parse commit messages for conventional commit patterns:

• feat: or feat(...) → Features
• fix: or fix(...) → Fixes
• BREAKING CHANGE: or ! → Breaking Changes
• chore:, refactor:, perf: → Improvements/Chores

6. Atomic Release

All steps must succeed or abort:

1. ✅ Pre-release checks pass
2. ✅ All files updated
3. ✅ CHANGELOG updated
4. ✅ Commit created
5. ✅ Tag created
6. Pushed to remote by User

If any step fails, rollback changes and report error.
