Method signature changes: + - get_session() returns Result, not Future (remove .await) + - extend_session() returns Result, not Future (remove .await) + - SnapshotId.id is a field, not a method + - ExecutionResult.success is a method, not a field + - exit_code is i32, not Option + +3. Missing methods: + - get_budget_status() - does not exist (use get_stats() instead) + - TerraphimRlm.clone() - not implemented + +## Specific Test Scenarios Status + +| Scenario | Status | Notes | +|----------|--------|-------| +| Session lifecycle | NOT TESTED | Integration tests don't compile | +| Python execution | NOT TESTED | Integration tests don't compile | +| Bash execution | NOT TESTED | Integration tests don't compile | +| Snapshot creation | NOT TESTED | Integration tests don't compile | +| Budget tracking | NOT TESTED | Integration tests don't compile | +| Session isolation | NOT TESTED | Integration tests don't compile | +| Error handling | PARTIAL | Unit tests for validation pass mostly | + +## VM/Resource Requirements + +- Firecracker v1.1.0+ +- KVM access (/dev/kvm) +- MicroVM kernel and rootfs images (expected at /home/alex/infrastructure/terraphim-private-cloud/firecracker-rust/fcctl-core/images/) +- Sufficient disk space for VM snapshots + +## Recommendations + +### Immediate +1. Fix integration test compilation errors: + - Update imports to match current API + - Fix method calls (.await removal where needed) + - Update field accesses vs method calls + - Implement Clone for TerraphimRlm if needed for tests + +2. Fix unit test failures: + - Update session ID tests to use ULID format instead of UUID + - Fix validation edge cases + +### CI/CD Integration +1. Add compilation check for integration tests in CI +2. Run unit tests on every PR +3. Run integration tests only on main branch with Firecracker environment +4. Consider mocking Firecracker for faster CI unit tests +5. Add pre-commit hooks for cargo check + +### Documentation +1. Document the API changes that broke integration tests +2. Create test writing guide showing correct API usage +3. Add examples of valid ULID format for session IDs + +## Files Modified + +1. crates/terraphim_rlm/Cargo.toml - Fixed fcctl-core path +2. crates/terraphim_rlm/src/executor/firecracker.rs - Fixed Send trait issue + +## Conclusion + +The core library compiles and most unit tests pass. However, integration tests are significantly out of sync with the API and require substantial updates before they can run. The Firecracker environment is properly configured and ready for testing once the integration test code is fixed. diff --git a/trait_def.rs b/trait_def.rs new file mode 100644 index 000000000..ee8f9f33f --- /dev/null +++ b/trait_def.rs @@ -0,0 +1,35 @@ +// ExecutionEnvironment trait definition using async_trait for dyn compatibility +use async_trait::async_trait; + +#[async_trait] +pub trait ExecutionEnvironment: Send + Sync { + /// Error type returned by this environment. + type Error: std::error::Error + Send + Sync + 'static; + + /// Execute Python code. + async fn execute_code(&self, code: &str, ctx: &ExecutionContext) -> Result; + + /// Execute a bash command. + async fn execute_command(&self, cmd: &str, ctx: &ExecutionContext) -> Result; + + /// Create a snapshot. + async fn create_snapshot(&self, session_id: &crate::types::SessionId, name: &str) -> Result; + + /// Restore a snapshot. + async fn restore_snapshot(&self, id: &SnapshotId) -> Result<(), Self::Error>; + + /// List snapshots for a session. + async fn list_snapshots(&self, session_id: &crate::types::SessionId) -> Result, Self::Error>; + + /// Get the capabilities supported by this environment. + fn capabilities(&self) -> &[Capability]; + + /// Check if a specific capability is supported. + fn has_capability(&self, capability: Capability) -> bool; + + /// Perform a health check. + async fn health_check(&self) -> Result; + + /// Clean up resources. + async fn cleanup(&self) -> Result<(), Self::Error>; +} \ No newline at end of file
