The original pre-push hook tried to export DB → JSONL during the push, then run 'git add', but this doesn't work because: 1. The commit is already created when pre-push runs 2. git add in pre-push stages files for a FUTURE commit 3. The current push sends the old commit with stale JSONL 4. Result: dirty git status after push Fix: - Pre-push now CHECKS for uncommitted JSONL changes - If found, it FAILS the push with clear instructions - User must commit JSONL before pushing - This prevents stale JSONL from reaching remote The pre-commit hook already properly flushes changes, so this catch-all prevents changes made BETWEEN commit and push.

# bd Git Hooks
|
|
|
|
This directory contains git hooks that integrate bd (beads) with your git workflow, preventing stale JSONL from being pushed to remote.
|
|
|
|
## The Problem
|
|
|
|
Two race conditions can occur:
|
|
|
|
1. **Between operations and commits**: Daemon auto-flush (5s debounce) may fire after commit
|
|
- User closes issue via MCP → daemon schedules flush (5 sec delay)
|
|
- User commits code changes → JSONL appears clean
|
|
- Daemon flush fires → JSONL modified after commit
|
|
- Result: dirty working tree showing JSONL changes
|
|
|
|
2. **Between commits and pushes**: Changes made after commit but before push (bd-my64)
|
|
- User commits → pre-commit hook flushes JSONL
|
|
- User adds comments or updates issues
|
|
- User pushes → outdated JSONL is pushed
|
|
- Result: remote has stale JSONL
|
|
|
|
## The Solution
|
|
|
|
These git hooks ensure bd changes are always synchronized with your commits and pushes:
|
|
|
|
- **pre-commit** - Flushes pending bd changes to JSONL before commit and stages it
|
|
- **pre-push** - Blocks push if JSONL has uncommitted changes (bd-my64)
|
|
- **post-merge** - Imports updated JSONL after git pull/merge
|
|
|
|
## Installation
|
|
|
|
### Quick Install
|
|
|
|
From your repository root:
|
|
|
|
```bash
|
|
./examples/git-hooks/install.sh
|
|
```
|
|
|
|
This will:
|
|
- Copy hooks to `.git/hooks/`
|
|
- Make them executable
|
|
- Back up any existing hooks
|
|
|
|
### Manual Install
|
|
|
|
```bash
|
|
cp examples/git-hooks/pre-commit .git/hooks/pre-commit
|
|
cp examples/git-hooks/pre-push .git/hooks/pre-push
|
|
cp examples/git-hooks/post-merge .git/hooks/post-merge
|
|
chmod +x .git/hooks/pre-commit .git/hooks/pre-push .git/hooks/post-merge
|
|
```
|
|
|
|
## How It Works
|
|
|
|
### pre-commit
|
|
|
|
Before each commit, the hook runs:
|
|
|
|
```bash
|
|
bd sync --flush-only
|
|
```
|
|
|
|
This:
|
|
1. Exports any pending database changes to `.beads/issues.jsonl`
|
|
2. Stages the JSONL file if modified
|
|
3. Allows the commit to proceed with clean state
|
|
|
|
The hook is silent on success, fast (no git operations), and safe (fails commit if flush fails).
|
|
|
|
### pre-push
|
|
|
|
Before each push, the hook checks:
|
|
|
|
```bash
|
|
git diff --quiet .beads/beads.jsonl
|
|
```
|
|
|
|
This prevents pushing stale JSONL by:
|
|
1. Checking if JSONL has uncommitted changes (working tree or staging)
|
|
2. Failing the push with clear error message if changes exist
|
|
3. Instructing user to commit JSONL before pushing again
|
|
|
|
This solves bd-my64: changes made between commit and push are caught before reaching remote.
|
|
|
|
### post-merge
|
|
|
|
After a git pull or merge, the hook runs:
|
|
|
|
```bash
|
|
bd import -i .beads/beads.jsonl
|
|
```
|
|
|
|
This ensures your local database reflects the merged state. The hook:
|
|
- Only runs if `.beads/beads.jsonl` exists (also checks `issues.jsonl` for backward compat)
|
|
- Imports any new issues or updates from the merge
|
|
- Warns on failure but doesn't block the merge
|
|
|
|
**Note:** With hash-based IDs (v0.20.1+), ID collisions don't occur - different issues get different hash IDs.
|
|
|
|
## Compatibility
|
|
|
|
- **Auto-sync**: Works alongside bd's automatic 5-second debounce
|
|
- **Direct mode**: Hooks work in both daemon and `--no-daemon` mode
|
|
- **Worktrees**: Safe to use with git worktrees
|
|
|
|
## Benefits
|
|
|
|
✅ No more dirty working tree after commits
|
|
✅ Database always in sync with git
|
|
✅ Automatic collision resolution on merge
|
|
✅ Fast and silent operation
|
|
✅ Optional - manual `bd sync` still works
|
|
|
|
## Uninstall
|
|
|
|
Remove the hooks:
|
|
|
|
```bash
|
|
rm .git/hooks/pre-commit .git/hooks/pre-push .git/hooks/post-merge
|
|
```
|
|
|
|
Your backed-up hooks (if any) are in `.git/hooks/*.backup-*`.
