From ea55f4fe4479ed764f29cbed7232fe32e47da2f5 Mon Sep 17 00:00:00 2001 From: Jose Celano Date: Wed, 3 Dec 2025 17:40:42 +0000 Subject: [PATCH 01/25] feat: [#217] add release and run CLI commands (no-op) Phase 1 of Issue #217: Presentation Layer - CLI Commands (No-Op) - Add Release command variant to Commands enum with environment parameter - Add Run command variant to Commands enum with environment parameter - Add routing cases in dispatch/router.rs (prints 'not implemented yet') - Update all test match statements to include new command variants - Fix rustdoc warning for unclosed HTML tag in documentation Both commands are now recognized by the CLI: - cargo run -- release - cargo run -- run The commands currently print 'not implemented yet' and return success.

Previously, most handlers returned StatePersistence(RepositoryError::NotFound) which was semantically incorrect - a missing environment is a configuration/usage error, not a persistence error. Changes: - Configure handler: Added EnvironmentNotFound variant with full Traceable implementation, help text, and tests - Destroy handler: Added EnvironmentNotFound variant with full Traceable implementation, help text, and tests - Provision handler: Added EnvironmentNotFound variant with full Traceable implementation, help text, and tests - Release handler: Use existing EnvironmentNotFound instead of StatePersistence(NotFound) - Run handler: Use existing EnvironmentNotFound instead of StatePersistence(NotFound) - Test handler: Added EnvironmentNotFound variant with full Traceable implementation, help text, and tests All EnvironmentNotFound errors now: - Use ErrorKind::Configuration (not StatePersistence) - Include the environment name for context - Provide comprehensive troubleshooting guidance in help() - Have proper test coverage This follows the pattern established by RegisterCommandHandler which correctly distinguished between environment not found (configuration error) and actual persistence failures. --- .../command_handlers/configure/errors.rs | 51 ++++- .../command_handlers/configure/handler.rs | 8 +- .../command_handlers/destroy/errors.rs | 50 ++++- .../command_handlers/destroy/handler.rs | 8 +- .../command_handlers/provision/errors.rs | 48 +++- .../command_handlers/provision/handler.rs | 8 +- .../command_handlers/release/handler.rs | 10 +- .../command_handlers/run/handler.rs | 7 +- .../command_handlers/test/errors.rs | 205 ++++++++++++++++++ .../command_handlers/test/handler.rs | 10 +- 10 files changed, 368 insertions(+), 37 deletions(-) diff --git a/src/application/command_handlers/configure/errors.rs b/src/application/command_handlers/configure/errors.rs index 8ba2a033..122bd4c9 100644 --- a/src/application/command_handlers/configure/errors.rs +++ b/src/application/command_handlers/configure/errors.rs @@ -6,6 +6,13 @@ use crate::shared::command::CommandError; /// Comprehensive error type for the `ConfigureCommandHandler` #[derive(Debug, thiserror::Error)] pub enum ConfigureCommandHandlerError { + /// Environment was not found in the repository + #[error("Environment not found: {name}")] + EnvironmentNotFound { + /// The name of the environment that was not found + name: String, + }, + #[error("Command execution failed: {0}")] Command(#[from] CommandError), @@ -19,6 +26,9 @@ pub enum ConfigureCommandHandlerError { impl crate::shared::Traceable for ConfigureCommandHandlerError { fn trace_format(&self) -> String { match self { + Self::EnvironmentNotFound { name } => { + format!("ConfigureCommandHandlerError: Environment not found - {name}") + } Self::Command(e) => { format!("ConfigureCommandHandlerError: Command execution failed - {e}") } @@ -34,15 +44,19 @@ impl crate::shared::Traceable for ConfigureCommandHandlerError { fn trace_source(&self) -> Option<&dyn crate::shared::Traceable> { match self { Self::Command(e) => Some(e), - Self::StatePersistence(_) | Self::InvalidState(_) => None, + Self::EnvironmentNotFound { .. } + | Self::StatePersistence(_) + | Self::InvalidState(_) => None, } } fn error_kind(&self) -> crate::shared::ErrorKind { match self { + Self::EnvironmentNotFound { .. } | Self::InvalidState(_) => { + crate::shared::ErrorKind::Configuration + } Self::Command(_) => crate::shared::ErrorKind::CommandExecution, Self::StatePersistence(_) => crate::shared::ErrorKind::StatePersistence, - Self::InvalidState(_) => crate::shared::ErrorKind::Configuration, } } } @@ -76,6 +90,25 @@ impl ConfigureCommandHandlerError { #[must_use] pub fn help(&self) -> &'static str { match self { + Self::EnvironmentNotFound { .. } => { + "Environment Not Found - Troubleshooting: + +1.

This validator is designed for the demo slice which uses a temporary mocked service +//! (nginx web server). Validation is performed from **inside** the VM via SSH. +//! +//! ## Future Enhancements (Real Services) +//! +//! When implementing real Torrust services (Tracker, Index), validation should be +//! extended to include **external accessibility testing**: +//! +//! 1. **External HTTP/UDP Validation**: Test service accessibility from outside the VM, +//! not just from inside. For example, if the HTTP tracker is on port 7070, we need +//! to verify it's reachable from the test runner machine. +//! +//! 2. **Firewall Rule Verification**: External tests will implicitly validate that +//! firewall rules (UFW/iptables) are correctly configured. If a service is running +//! inside but not accessible from outside, it indicates a firewall misconfiguration. +//! +//! 3. **Both Internal and External Checks**: Consider running both types of validation: +//! - Internal (via SSH): Confirms service is running inside the container/VM +//! - External (from test runner): Confirms service is accessible through the network +//! +//!

The validator performs multiple checks: +//! 1. Execute `docker compose ps` to verify services are listed +//! 2. Check that containers are in "running" status (not "exited" or "restarting") +//! 3. Verify health check status if configured (e.g., "healthy") +//! 4. Test HTTP accessibility for web services (optional) +//! +//!
