Introduce three migrations: admin permissions (is_admin + permissions table),
BYOC team tracking, and multi-host support (hosts, host_tokens, host_tags).
Add Redis to dev infra and wire up client in control plane for ephemeral
host registration tokens. Add go-redis dependency.
Implement OAuth 2.0 login via GitHub as an alternative to email/password.
Uses a provider registry pattern (internal/auth/oauth/) so adding Google
or other providers later requires only a new Provider implementation.
Flow: GET /v1/auth/oauth/github redirects to GitHub, callback exchanges
the code for a user profile, upserts the user + team atomically, and
redirects to the frontend with a JWT token.
Key changes:
- Migration: make password_hash nullable, add oauth_providers table
- Provider registry with GitHubProvider (profile + email fallback)
- CSRF state cookie with HMAC-SHA256 validation
- Race-safe registration (23505 collision retries as login)
- Startup validation: CP_PUBLIC_URL required when OAuth is configured
Not fully tested — needs integration tests with a real GitHub OAuth app
and end-to-end testing with the frontend callback page.
Implement email/password auth with JWT sessions and API key auth for
sandbox lifecycle. Users get a default team on signup; sandboxes,
snapshots, and API keys are scoped to teams.
- Add user, team, users_teams, and team_api_keys tables (goose migrations)
- Add JWT middleware (Bearer token) for user management endpoints
- Add API key middleware (X-API-Key header, SHA-256 hashed) for sandbox ops
- Add signup/login handlers with transactional user+team creation
- Add API key CRUD endpoints (create/list/delete)
- Replace owner_id with team_id on sandboxes and templates
- Update all handlers to use team-scoped queries
- Add godotenv for .env file loading
- Update OpenAPI spec and test UI with auth flows
Implement full snapshot lifecycle: pause (snapshot + free resources),
resume (UFFD-based lazy restore), and named snapshot templates that
can spawn new sandboxes from frozen VM state.
Key changes:
- Snapshot header system with generational diff mapping (inspired by e2b)
- UFFD server for lazy page fault handling during snapshot restore
- Stable rootfs symlink path (/tmp/fc-vm/) for snapshot compatibility
- Templates DB table and CRUD API endpoints (POST/GET/DELETE /v1/snapshots)
- CreateSnapshot/DeleteSnapshot RPCs in hostagent proto
- Reconciler excludes paused sandboxes (expected absent from host agent)
- Snapshot templates lock vcpus/memory to baked-in values
- Proper cleanup of uffd sockets and pause snapshot files on destroy
