Add configuration validation (#10) - #20
Conversation
📝 WalkthroughWalkthroughThe startup process now validates required manager and worker environment variables and port values. Invalid configuration produces an error and exits before normal environment loading or worker startup continues. ChangesConfiguration validation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to Role-specific configuration can still fail with a raw TypeError after validation succeeds when the other role's port is absent, so the PR is not merge-ready until configuration loading is made role-aware or both role blocks are validated consistently. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)
✅ Passed checks (4 passed)
Full details: Linked Issues checkExplanation The changes add the required Manager and Worker variable lists, validate missing variables and invalid or non-numeric ports, report configuration guidance, and invoke role-specific validation during startup initialization.

Make role-specific validation compatible with Env.get_all(). Env.validate_manager() can pass without WORKER_PORT, but machines/manager.py then calls Env.get_all(), which unconditionally converts the missing value and raises TypeError. Env.validate_worker() has the inverse failure for MANAGER_PORT. Make Env.get_all() role-aware, or enforce both configuration blocks in both validators.

Thank you for this feature! Btw sorry for taking so long to reply |

Fixes #10
Adds Env.validate_manager() and Env.validate_worker(), checking each
role's required vars (Manager: TOKEN/HOST/PORT/HOSTNAME, Worker:
ID/TOKEN/HOST/PORT/HOSTNAME). Catches missing vars and invalid ports
with a clear message instead of a raw crash.
manager.py and worker.py each call their own validator before loading
config.
Tested manually: valid config works; missing var, bad port range, and
non-numeric port each produce a clean error + exit 1.
