# Homebrew Tap Update Summary - Version 0.14.3

## Status: ⚠️ NON-BLOCKING FAILURE

**Date:** 2025-12-01
**Version:** 0.14.3
**Result:** PyPI package not yet available after retry attempts

---

## What Happened

The Homebrew tap update process was executed for version 0.14.3, but the PyPI package was not yet available after multiple retry attempts with exponential backoff.

### Retry Details

- **Max Attempts:** 10
- **Total Timeout:** 5 minutes (300 seconds)
- **Actual Runtime:** ~316 seconds
- **Backoff Strategy:** Exponential (5s → 10s → 20s → 40s → 60s → 60s...)
- **Final Result:** Timeout reached, package not found on PyPI

### Current PyPI Status

- **Latest Available Version:** 0.14.2
- **Last Upload Time:** 2025-12-01T18:39:46
- **Target Version (0.14.3):** Not yet available

---

## Automation Scripts Created

### 1. `/scripts/wait_and_update_homebrew.sh`

A robust bash script that:
- Checks PyPI package availability
- Implements retry logic with exponential backoff
- Provides clear status messages and progress
- Exits with code 2 for NON-BLOCKING failures
- Generates detailed manual fallback instructions

**Usage:**
```bash
./scripts/wait_and_update_homebrew.sh 0.14.3
```

### 2. Makefile Target: `homebrew-update-wait`

Added to Makefile for easy integration:
```bash
make homebrew-update-wait
```

This target:
- Automatically detects current version
- Runs the wait-and-update script
- Treats failures as NON-BLOCKING (always exits 0)

---

## Manual Fallback Instructions

If the package is now available on PyPI, you can manually update the Homebrew formula:

### Option 1: Using the Automated Script

```bash
# Set your GitHub token
export HOMEBREW_TAP_TOKEN=<your-github-personal-access-token>

# Run the update script
python3 scripts/update_homebrew_formula.py --version 0.14.3 --verbose
```

### Option 2: Using the Wait Script

```bash
# Set your GitHub token
export HOMEBREW_TAP_TOKEN=<your-github-personal-access-token>

# Run with automatic retry
./scripts/wait_and_update_homebrew.sh 0.14.3
```

### Option 3: Using Make

```bash
# Set your GitHub token
export HOMEBREW_TAP_TOKEN=<your-github-personal-access-token>

# Run via Make
make homebrew-update-wait
```

### Option 4: Manual Update

```bash
# Clone the tap repository
cd $(mktemp -d)
git clone https://github.com/bobmatnyc/homebrew-mcp-vector-search.git
cd homebrew-mcp-vector-search

# Get SHA256 from PyPI
PYPI_SHA256=$(curl -s https://pypi.org/pypi/mcp-vector-search/0.14.3/json | \
  python3 -c "import sys, json; \
  data = json.load(sys.stdin); \
  sdist = [r for r in data['urls'] if r['packagetype'] == 'sdist'][0]; \
  print(sdist['digests']['sha256'])")

# Update formula
sed -i '' "s/version \"[^\"]*\"/version \"0.14.3\"/g" Formula/mcp-vector-search.rb
sed -i '' "s/sha256 \"[^\"]*\"/sha256 \"$PYPI_SHA256\"/g" Formula/mcp-vector-search.rb

# Verify changes
git diff Formula/mcp-vector-search.rb

# Commit and push
git add Formula/mcp-vector-search.rb
git commit -m "chore: update formula to 0.14.3"
git push origin main
```

## Prerequisites

### GitHub Personal Access Token

You need a GitHub Personal Access Token with `repo` scope:

1. Go to https://github.com/settings/tokens
2. Click "Generate new token (classic)"
3. Select scope: `repo` (Full control of private repositories)
4. Copy the token
5. Export it: `export HOMEBREW_TAP_TOKEN=<your-token>`

### Repository Access

Ensure you have push access to:
- https://github.com/bobmatnyc/homebrew-mcp-vector-search

---

## Verification Steps

After successfully updating the formula, verify:

### 1. Check Formula Syntax
```bash
ruby -c Formula/mcp-vector-search.rb
```

### 2. Test Installation (if Homebrew installed)
```bash
brew tap bobmatnyc/mcp-vector-search
brew install --build-from-source mcp-vector-search
mcp-vector-search --version  # Should show 0.14.3
```

### 3. Verify on GitHub
Check the commit in the tap repository:
https://github.com/bobmatnyc/homebrew-mcp-vector-search/commits/main

---

## Why This Failed (Non-Blocking)

This is a **NON-BLOCKING** failure, meaning it doesn't stop the release process. The reasons are:

1. **PyPI Propagation Delay:** PyPI can take 5-10 minutes to process and index new packages
2. **Dependency:** Homebrew formula updates depend on PyPI package availability
3. **Priority:** PyPI release success is more critical than Homebrew tap updates
4. **Recovery:** Can be manually updated later without blocking the release

### This Is Expected Behavior

The automation is designed to:
- Try multiple times with increasing delays
- Timeout gracefully after 5 minutes
- Provide clear manual instructions
- Allow the release process to continue

---

## Next Steps

### If Version 0.14.3 is Now Available on PyPI

1. Check availability: https://pypi.org/project/mcp-vector-search/0.14.3/
2. Follow one of the manual fallback instructions above
3. Verify the installation works

### If Version 0.14.3 is Still Not Available

1. Check the PyPI release process
2. Verify the package was successfully uploaded
3. Wait longer (PyPI can take up to 10-15 minutes in rare cases)
4. Check for errors in the PyPI upload process

## Files Modified

- ✅ Created: `/scripts/wait_and_update_homebrew.sh`
- ✅ Modified: `/Makefile` (added `homebrew-update-wait` target)
- ✅ Created: `/HOMEBREW_TAP_UPDATE_SUMMARY.md` (this file)

- `/scripts/HOMEBREW_WORKFLOW.md` - Complete workflow documentation
- `/scripts/HOMEBREW_QUICKSTART.md` - Quick start guide

---

## Exit Codes

The scripts use specific exit codes for automation:

- **0:** Success - Formula updated and pushed
- **1:** Hard failure - PyPI API error, invalid package
- **2:** Soft failure (NON-BLOCKING) - Package not yet available, timeout
- **5:** Authentication failure - HOMEBREW_TAP_TOKEN invalid or missing

Exit code **2** indicates this is a non-blocking failure that can be retried later.

## Evidence of Execution

### Script Output
```
==========================================
Homebrew Tap Update - Version 0.14.3
==========================================

This is a NON-BLOCKING operation
Will retry up to 10 times with exponential backoff
Total timeout: 300 seconds

Attempt 1/10: Checking if version 0.14.3 is available on PyPI...
✗ Version 0.14.3 not yet available on PyPI
⏱️  Waiting 5s before next attempt...

[... 7 more attempts ...]

⏱️  Timeout reached after 316s
==========================================
⚠️  Could not update Homebrew formula
==========================================

Version 0.14.3 is not yet available on PyPI after 9 attempts (316s)

This is a NON-BLOCKING failure - continuing with release process
```

### Verification Commands Run
```bash
# Check PyPI availability
curl -s https://pypi.org/pypi/mcp-vector-search/0.14.3/json
# Result: 404 Not Found

# Check latest version
curl -s https://pypi.org/pypi/mcp-vector-search/json | \
  python3 -c "import sys, json; print(json.load(sys.stdin)['info']['version'])"
# Result: 0.14.2
```

## Conclusion

The Homebrew tap update for version 0.14.3 was **gracefully deferred** due to PyPI package availability. This is a known edge case in the release automation and is handled correctly as a non-blocking failure.

**The release process can continue safely.**

To complete the Homebrew tap update, follow the manual instructions once the PyPI package is confirmed available.

---

**Status:** 🟡 Deferred (Non-Blocking)
**Action Required:** Manual update when PyPI package is available
**Impact:** Low (Homebrew users can still install from PyPI)
**Urgency:** Medium (can be completed within 24 hours)
