Remove StrictHostKeyChecking=no from SSH commands (#315)
* Remove StrictHostKeyChecking=no and implement proper host key verification This commit addresses security concerns from the OWASP audit by enforcing strict host key verification for all SSH and SCP commands. Key changes: - Replaced StrictHostKeyChecking=accept-new with yes in pkg/container and pkg/devops. - Removed insecure host key verification from pkg/ansible SSH client. - Implemented a synchronous host key discovery mechanism during VM boot using ssh-keyscan to populate ~/.core/known_hosts. - Updated the devops Boot lifecycle to wait until the host key is verified. - Ensured pkg/ansible correctly handles missing known_hosts files. - Refactored hardcoded SSH port 2222 to a package constant DefaultSSHPort. - Added CORE_SKIP_SSH_SCAN environment variable for test environments. * Remove StrictHostKeyChecking=no and implement proper host key verification Addresses security concerns from OWASP audit by enforcing strict host key verification. Changes: - Replaced StrictHostKeyChecking=accept-new with yes in pkg/container and devops. - Removed insecure host key verification from pkg/ansible. - Added synchronous host key discovery using ssh-keyscan during VM boot. - Updated Boot lifecycle to wait for host key verification. - Handled missing known_hosts file in pkg/ansible. - Refactored hardcoded SSH port to DefaultSSHPort constant. - Fixed formatting issues identified by QA check. * Secure SSH commands and fix auto-merge CI failure Addresses OWASP security audit by enforcing strict host key verification and fixes a CI failure in the auto-merge workflow.

# ADR 0001: Use Wails v3 for GUI
|
||||
|
||||
* Status: accepted
|
||||
* Deciders: Project Maintainers
|
||||
* Date: 2025-05-15
|
||||
|
||||
## Context and Problem Statement
|
||||
|
||||
The project needs a way to build cross-platform desktop applications with a modern UI. Historically, Electron has been the go-to choice, but it is known for its high resource consumption and large binary sizes.
|
||||
|
||||
## Decision Drivers
|
||||
|
||||
* Performance and resource efficiency.
|
||||
* Smaller binary sizes.
|
||||
* Tight integration with Go.
|
||||
* Native look and feel.
|
||||
|
||||
## Considered Options
|
||||
|
||||
* Electron
|
||||
* Wails (v2)
|
||||
* Wails (v3)
|
||||
* Fyne
|
||||
|
||||
## Decision Outcome
|
||||
|
||||
Chosen option: "Wails (v3)", because it provides the best balance of using web technologies for the UI while keeping the backend in Go with minimal overhead. Wails v3 specifically offers improvements in performance and features over v2.
|
||||
|
||||
### Positive Consequences
|
||||
|
||||
* Significantly smaller binary sizes compared to Electron.
|
||||
* Reduced memory usage.
|
||||
* Ability to use any frontend framework (Vue, React, Svelte, etc.).
|
||||
* Direct Go-to-JS bindings.
|
||||
|
||||
### Negative Consequences
|
||||
|
||||
* Wails v3 is still in alpha/beta, which might lead to breaking changes or bugs.
|
||||
* Smaller ecosystem compared to Electron.

# ADR 0002: IPC Bridge Pattern
|
||||
|
||||
* Status: accepted
|
||||
* Deciders: Project Maintainers
|
||||
* Date: 2025-05-15
|
||||
|
||||
## Context and Problem Statement
|
||||
|
||||
Wails allows direct binding of Go methods to the frontend. However, as the number of services and methods grows, managing individual bindings for every service becomes complex. We need a way to decouple the frontend from the internal service structure.
|
||||
|
||||
## Decision Drivers
|
||||
|
||||
* Decoupling services from the frontend runtime.
|
||||
* Simplified binding generation.
|
||||
* Centralized message routing.
|
||||
* Uniform internal and external communication.
|
||||
|
||||
## Considered Options
|
||||
|
||||
* Direct Wails Bindings for all services.
|
||||
* IPC Bridge Pattern (Centralized ACTION handler).
|
||||
|
||||
## Decision Outcome
|
||||
|
||||
Chosen option: "IPC Bridge Pattern", because it allows services to remain agnostic of the frontend runtime. Only the `Core` service is registered with Wails, and it exposes a single `ACTION` method that routes messages to the appropriate service based on an IPC handler.
|
||||
|
||||
### Positive Consequences
|
||||
|
||||
* Only one Wails service needs to be registered.
|
||||
* Services can be tested independently of Wails.
|
||||
* Adding new functionality to a service doesn't necessarily require regenerating frontend bindings.
|
||||
* Consistency between frontend-to-backend and backend-to-backend communication.
|
||||
|
||||
### Negative Consequences
|
||||
|
||||
* Less type safety out-of-the-box in the frontend for specific service methods (though this can be improved with manual type definitions or codegen).
|
||||
* Requires services to implement `HandleIPCEvents`.

# ADR 0003: Service-Oriented Architecture with Dual-Constructor DI
|
||||
|
||||
* Status: accepted
|
||||
* Deciders: Project Maintainers
|
||||
* Date: 2025-05-15
|
||||
|
||||
## Context and Problem Statement
|
||||
|
||||
The application consists of many components (config, crypt, workspace, etc.) that depend on each other. We need a consistent way to manage these dependencies and allow for easy testing.
|
||||
|
||||
## Decision Drivers
|
||||
|
||||
* Testability.
|
||||
* Modularity.
|
||||
* Ease of service registration.
|
||||
* Clear lifecycle management.
|
||||
|
||||
## Considered Options
|
||||
|
||||
* Global variables/singletons.
|
||||
* Dependency Injection (DI) container.
|
||||
* Manual Dependency Injection.
|
||||
|
||||
## Decision Outcome
|
||||
|
||||
Chosen option: "Service-Oriented Architecture with Dual-Constructor DI". Each service follows a pattern where it provides a `New()` constructor for standalone use/testing (static DI) and a `Register()` function for registration with the `Core` service container (dynamic DI).
|
||||
|
||||
### Positive Consequences
|
||||
|
||||
* Easy to unit test services by passing mock dependencies to `New()`.
|
||||
* Automatic service discovery and lifecycle management via `Core`.
|
||||
* Decoupled components.
|
||||
|
||||
### Negative Consequences
|
||||
|
||||
* Some boilerplate required for each service (`New` and `Register`).
|
||||
* Dependency on `pkg/core` for `Register`.

# ADR 0004: Storage Abstraction via Medium Interface
|
||||
|
||||
* Status: accepted
|
||||
* Deciders: Project Maintainers
|
||||
* Date: 2025-05-15
|
||||
|
||||
## Context and Problem Statement
|
||||
|
||||
The application needs to support different storage backends (local file system, SFTP, WebDAV, etc.) for its workspace data. Hardcoding file system operations would make it difficult to support remote storage.
|
||||
|
||||
## Decision Drivers
|
||||
|
||||
* Flexibility in storage backends.
|
||||
* Ease of testing (mocking storage).
|
||||
* Uniform API for file operations.
|
||||
|
||||
## Considered Options
|
||||
|
||||
* Standard `os` package.
|
||||
* Interface abstraction (`Medium`).
|
||||
* `spf13/afero` library.
|
||||
|
||||
## Decision Outcome
|
||||
|
||||
Chosen option: "Interface abstraction (`Medium`)". We defined a custom `Medium` interface in `pkg/io` that abstracts common file operations.
|
||||
|
||||
### Positive Consequences
|
||||
|
||||
* Application logic is agnostic of where files are actually stored.
|
||||
* Easy to implement new backends (SFTP, WebDAV).
|
||||
* Simplified testing using `MockMedium`.
|
||||
|
||||
### Negative Consequences
|
||||
|
||||
* Small overhead of interface calls.
|
||||
* Need to ensure all file operations go through the `Medium` interface.

# Architecture Decision Records (ADR)
|
||||
|
||||
This directory contains the Architecture Decision Records for the Core project.
|
||||
|
||||
## What is an ADR?
|
||||
|
||||
An Architecture Decision Record (ADR) is a document that captures an important architectural decision made along with its context and consequences.
|
||||
|
||||
## Why use ADRs?
|
||||
|
||||
- **Context:** Helps new contributors understand *why* certain decisions were made.
|
||||
- **History:** Provides a historical record of the evolution of the project's architecture.
|
||||
- **Transparency:** Makes the decision-making process transparent and open for discussion.
|
||||
|
||||
## ADR Process
|
||||
|
||||
1. **Identify a Decision:** When an architectural decision needs to be made, start a new ADR.
|
||||
2. **Use the Template:** Copy `0000-template.md` to a new file named `NNNN-short-title.md` (e.g., `0001-use-wails-v3.md`).
|
||||
3. **Draft the ADR:** Fill in the context, drivers, and considered options.
|
||||
4. **Propose:** Set the status to `proposed` and open a Pull Request for discussion.
|
||||
5. **Accept/Reject:** Once a consensus is reached, update the status to `accepted` or `rejected` and merge.
|
||||
6. **Supersede:** If a later decision changes an existing one, update the status of the old ADR to `superseded` and point to the new one.
