npm run lint
if [ $? -ne 0 ]; then
    echo "Linting failed. Commit aborted."
    exit 1
fi

# Check for forbidden words
if grep -r "TODO\|FIXME\|console.log" --include="*.js" src/; then
    echo "Found TODO, FIXME, or console.log in code."
    echo "Please remove before committing."
    exit 1
fi

    echo "Direct push to $protected_branch is not allowed."
    echo "Please use pull requests."
    exit 1

  https://gitlab.com/api/v4/projects/123/repository/commits

Monitoring and Observability

Git Metrics

Repository Metrics Script:

#!/bin/bash
# git-metrics.sh

# Basic statistics
echo "Repository Statistics:"
echo "====================="
echo "Total commits: $(git rev-list --all --count)"
echo "Total branches: $(git branch -a | wc -l)"
echo "Total contributors: $(git shortlog -sn | wc -l)"
echo "Repository size: $(du -sh .git | cut -f1)"

# Recent activity
echo -e "\nRecent Activity:"
echo "==============="
echo "Commits this week: $(git log --since='1 week ago' --oneline | wc -l)"
echo "Commits this month: $(git log --since='1 month ago' --oneline | wc -l)"

# Top contributors
echo -e "\nTop Contributors:"
echo "================"
git shortlog -sn | head -5

# Branch activity
echo -e "\nActive Branches:"
echo "==============="
git for-each-ref --sort=-committerdate refs/heads/ \
  --format='%(committerdate:short) %(refname:short)' | head -10

Integration with Monitoring Tools

Prometheus Integration:

# Export Git metrics for Prometheus
#!/bin/bash
# git-prometheus-exporter.sh

REPO_PATH="/path/to/repo"
METRICS_FILE="/tmp/git-metrics.prom"

cd $REPO_PATH

# Repository size
REPO_SIZE=$(du -sb .git | cut -f1)
echo "git_repository_size_bytes{repo=\"$(basename $PWD)\"} $REPO_SIZE" > $METRICS_FILE

# Commit count
COMMIT_COUNT=$(git rev-list --all --count)
echo "git_total_commits{repo=\"$(basename $PWD)\"} $COMMIT_COUNT" >> $METRICS_FILE

# Recent commits
RECENT_COMMITS=$(git log --since='1 week ago' --oneline | wc -l)
echo "git_recent_commits{repo=\"$(basename $PWD)\",period=\"week\"} $RECENT_COMMITS" >> $METRICS_FILE

# Branch count
BRANCH_COUNT=$(git branch -a | wc -l)
echo "git_total_branches{repo=\"$(basename $PWD)\"} $BRANCH_COUNT" >> $METRICS_FILE

Troubleshooting Integration Issues

Common Problems

IDE not detecting Git repository

# Check if .git directory exists
ls -la .git

# Reinitialize if needed
git init

# Check IDE Git settings
# Ensure Git executable path is correct

CI/CD not triggering

# Check webhook configuration
# Verify branch protection rules
# Check CI configuration file syntax

# Test webhook locally
curl -X POST -H "Content-Type: application/json" \
  -d '{"ref":"refs/heads/main"}' \
  https://your-ci-webhook-url

Hooks not executing

# Check hook permissions
chmod +x .git/hooks/pre-commit

# Verify hook syntax
bash -n .git/hooks/pre-commit

# Test hook manually
.git/hooks/pre-commit

Debug Integration

# Debug Git operations
GIT_TRACE=1 git push origin main

# Debug SSH connections
GIT_SSH_COMMAND="ssh -v" git push origin main

# Debug HTTP operations
GIT_CURL_VERBOSE=1 git push origin main

Best Practices

Integration Guidelines

Automate repetitive tasks - Use hooks and CI/CD
Maintain consistency - Standardize tools and workflows
Monitor performance - Track repository and build metrics
Document integrations - Keep setup instructions current
Test integrations - Verify tools work together

Security Considerations

Protect secrets - Use secure credential storage
Validate inputs - Check webhook payloads
Limit permissions - Use least privilege principle
Monitor access - Track API usage and authentication
Regular updates - Keep tools and dependencies current

Performance Optimization

Cache dependencies - Speed up CI/CD builds
Parallel execution - Run tests and builds concurrently
Incremental operations - Only process changed files
Optimize clones - Use shallow clones when possible
Monitor resource usage - Track build times and costs

See Configuration for tool-specific settings and Performance for optimization techniques.
