This curriculum spans the design and operational demands of enterprise source code management, comparable to a multi-workshop program for establishing internal development standards across large-scale, regulated software environments.
Module 1: Repository Architecture and Project Structuring
- Decide between monorepo and polyrepo strategies based on team autonomy, dependency management, and CI/CD pipeline complexity.
- Implement directory hierarchies that enforce separation of concerns across services, libraries, and configuration artifacts.
- Enforce consistent naming conventions for branches, tags, and repositories to support automated tooling and auditability.
- Structure repository access controls to align with team roles while minimizing privilege escalation risks.
- Integrate environment-specific configuration files without exposing secrets in version control.
- Design repository split strategies when migrating legacy applications into modular components.
Module 2: Branching Models and Workflow Design
- Select and standardize a branching model (e.g., GitFlow, Trunk-Based) based on release frequency and testing maturity.
- Define merge request requirements including mandatory reviewers, status checks, and dependency validation.
- Implement short-lived feature branches with enforced pull request templates and automated labeling.
- Manage long-running release branches when supporting multiple customer versions simultaneously.
- Coordinate hotfix workflows that bypass standard staging while maintaining traceability.
- Resolve merge conflicts in shared libraries without disrupting dependent teams’ development cycles.
Module 3: Access Control and Identity Management
- Map IAM roles to repository permissions using group-based policies across development, QA, and production environments.
- Enforce two-person approval rules for critical branches using branch protection policies.
- Rotate and audit deploy keys and personal access tokens on a scheduled basis.
- Integrate SSO with the source control platform to centralize identity lifecycle management.
- Restrict direct push access to main branches and require all changes to flow through pull requests.
- Implement least-privilege access for CI/CD service accounts interacting with repositories.
Module 4: Integration with CI/CD Toolchains
- Configure webhooks to trigger pipeline executions only on specific branches and file path changes.
- Cache dependencies across builds to reduce execution time while ensuring cache invalidation correctness.
- Validate merge requests with automated linting, unit tests, and security scans before approval.
- Enforce artifact immutability by linking build outputs to specific commit SHAs.
- Orchestrate parallel testing across multiple environments triggered by a single commit.
- Fail fast in pipelines by running smoke tests before resource-intensive integration suites.
Module 5: Code Review and Collaboration Standards
- Define review criteria for architectural impact, test coverage, and performance implications.
- Enforce mandatory comments on changed lines to ensure reviewers examine all modifications.
- Use automated code annotation tools to highlight complexity hotspots during review.
- Track reviewer response times and rotate ownership to prevent bottlenecks.
- Integrate static analysis findings directly into pull request comments for immediate feedback.
- Archive outdated discussions and resolve comments to maintain clarity in active reviews.
Module 6: Auditability, Compliance, and Retention
- Enable full audit logging of repository events including deletions, permission changes, and merges.
- Configure retention policies for branches and pull requests to prevent unbounded sprawl.
- Preserve historical access logs for compliance with regulatory frameworks such as SOC 2 or HIPAA.
- Implement immutable tagging for production releases to support forensic investigations.
- Enforce signed commits using GPG or S/MIME to verify authorship in regulated environments.
- Archive inactive repositories with a documented process for potential future retrieval.
Module 7: Tooling Migration and Platform Interoperability
- Plan repository migration from legacy systems (e.g., SVN, TFS) while preserving full commit history.
- Reconcile divergent branching strategies when consolidating tools across acquired teams.
- Implement bidirectional sync mechanisms for distributed teams using different platforms.
- Standardize Git hooks across local environments to enforce pre-commit validation.
- Evaluate self-hosted vs. SaaS source control platforms based on data residency requirements.
- Automate metadata extraction during migration to maintain issue tracking and pull request linkage.
Module 8: Performance and Scalability Optimization
- Implement shallow clones in CI environments to reduce bandwidth and execution overhead.
- Use Git LFS for managing large binary assets without degrading repository performance.
- Partition monorepos using sparse checkouts to allow selective file access.
- Monitor and optimize garbage collection schedules on self-hosted Git servers.
- Diagnose and mitigate latency issues in geographically distributed development teams.
- Enforce file size limits and block prohibited file types at the pre-receive hook level.
