Nikolai TillmannandClaude Fable 5 512c1c3630 Fix busy loop in tart exec -i after piped stdin reaches EOF (#1281 )

Unregister the stdin readabilityHandler when availableData returns empty:
a closed pipe fd stays permanently readable, so Foundation re-invokes the
handler in a tight loop (fstat + zero-byte read) at 100% of one core for
the rest of the command's lifetime.

Fixes #1280

README.md

Tart is a virtualization toolset to build, run and manage macOS and Linux virtual machines (VMs) on Apple Silicon. Built by CI engineers for your automation needs. Here are some highlights of Tart:

Tart uses Apple's own Virtualization.Framework for near-native performance.
Push/Pull virtual machines from any OCI-compatible container registry.
Use Tart Packer Plugin to automate VM creation.
Easily integrates with any CI system.

Many companies are using Tart in their internal setups. Here are just a few of them:

Note: If your company or project is using Tart please consider sharing with the community.

Usage

Try running a Tart VM on your Apple Silicon device running macOS 13.0 (Ventura) or later (will download a 25 GB image):

brew install openai/tools/tart
tart clone ghcr.io/cirruslabs/macos-tahoe-base:latest tahoe-base
tart run tahoe-base
