This commit implements Phase 2 of the CHORUS Task Execution Engine development plan, providing a comprehensive execution environment abstraction layer with Docker container sandboxing support. ## New Features ### Core Sandbox Interface - Comprehensive ExecutionSandbox interface with isolated task execution - Support for command execution, file I/O, environment management - Resource usage monitoring and sandbox lifecycle management - Standardized error handling with SandboxError types and categories ### Docker Container Sandbox Implementation - Full Docker API integration with secure container creation - Transparent repository mounting with configurable read/write access - Advanced security policies with capability dropping and privilege controls - Comprehensive resource limits (CPU, memory, disk, processes, file handles) - Support for tmpfs mounts, masked paths, and read-only bind mounts - Container lifecycle management with proper cleanup and health monitoring ### Security & Resource Management - Configurable security policies with SELinux, AppArmor, and Seccomp support - Fine-grained capability management with secure defaults - Network isolation options with configurable DNS and proxy settings - Resource monitoring with real-time CPU, memory, and network usage tracking - Comprehensive ulimits configuration for process and file handle limits ### Repository Integration - Seamless repository mounting from local paths to container workspaces - Git configuration support with user credentials and global settings - File inclusion/exclusion patterns for selective repository access - Configurable permissions and ownership for mounted repositories ### Testing Infrastructure - Comprehensive test suite with 60+ test cases covering all functionality - Docker integration tests with Alpine Linux containers (skipped in short mode) - Mock sandbox implementation for unit testing without Docker dependencies - Security policy validation tests with read-only filesystem enforcement - Resource usage monitoring and cleanup verification tests ## Technical Details ### Dependencies Added - github.com/docker/docker v28.4.0+incompatible - Docker API client - github.com/docker/go-connections v0.6.0 - Docker connection utilities - github.com/docker/go-units v0.5.0 - Docker units and formatting - Associated Docker API dependencies for complete container management ### Architecture - Interface-driven design enabling multiple sandbox implementations - Comprehensive configuration structures for all sandbox aspects - Resource usage tracking with detailed metrics collection - Error handling with retryable error classification - Proper cleanup and resource management throughout sandbox lifecycle ### Compatibility - Maintains backward compatibility with existing CHORUS architecture - Designed for future integration with Phase 3 Core Task Execution Engine - Extensible design supporting additional sandbox implementations (VM, process) This Phase 2 implementation provides the foundation for secure, isolated task execution that will be integrated with the AI model providers from Phase 1 in the upcoming Phase 3 development. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

|
|
|
This repository contains utilities for efficiently performing Win32 IO operations in
|
|
Go. Currently, this is focused on accessing named pipes and other file handles, and
|
|
for using named pipes as a net transport.
|
|
|
|
This code relies on IO completion ports to avoid blocking IO on system threads, allowing Go
|
|
to reuse the thread to schedule another goroutine. This limits support to Windows Vista and
|
|
newer operating systems. This is similar to the implementation of network sockets in Go's net
|
|
package.

## Contributing
|
|
|
|
This project welcomes contributions and suggestions.
|
|
Most contributions require you to agree to a Contributor License Agreement (CLA) declaring that
|
|
you have the right to, and actually do, grant us the rights to use your contribution.
|
|
For details, visit [Microsoft CLA](https://cla.microsoft.com).
|
|
|
|
When you submit a pull request, a CLA-bot will automatically determine whether you need to
|
|
provide a CLA and decorate the PR appropriately (e.g., label, comment).
|
|
Simply follow the instructions provided by the bot.
|
|
You will only need to do this once across all repos using our CLA.
|
|
|
|
Additionally, the pull request pipeline requires the following steps to be performed before
|
|
mergining.
|
|
|
|
### Code Sign-Off
|
|
|
|
We require that contributors sign their commits using [`git commit --signoff`][git-commit-s]
|
|
to certify they either authored the work themselves or otherwise have permission to use it in this project.
|
|
|
|
A range of commits can be signed off using [`git rebase --signoff`][git-rebase-s].
|
|
|
|
Please see [the developer certificate](https://developercertificate.org) for more info,
|
|
as well as to make sure that you can attest to the rules listed.
|
|
Our CI uses the DCO Github app to ensure that all commits in a given PR are signed-off.
|
|
|
|
### Linting
|
|
|
|
Code must pass a linting stage, which uses [`golangci-lint`][lint].
|
|
The linting settings are stored in [`.golangci.yaml`](./.golangci.yaml), and can be run
|
|
automatically with VSCode by adding the following to your workspace or folder settings:
|
|
|
|
```json
|
|
"go.lintTool": "golangci-lint",
|
|
"go.lintOnSave": "package",
|
|
```
|
|
|
|
Additional editor [integrations options are also available][lint-ide].
|
|
|
|
Alternatively, `golangci-lint` can be [installed locally][lint-install] and run from the repo root:
|
|
|
|
```shell
|
|
# use . or specify a path to only lint a package
|
|
# to show all lint errors, use flags "--max-issues-per-linter=0 --max-same-issues=0"
|
|
> golangci-lint run ./...
|
|
```
|
|
|
|
### Go Generate
|
|
|
|
The pipeline checks that auto-generated code, via `go generate`, are up to date.
|
|
|
|
This can be done for the entire repo:
|
|
|
|
```shell
|
|
> go generate ./...
|
|
```
|
|
