Sean McLoughlin 3f1624e31a fix(control-socket): use .path instead of .path() for stale socket cleanup
Use URL's .path property instead of .path() method when removing stale
control sockets in ControlSocket.run(). The .path() method returns only
the relative component ('control.sock') while .path resolves to the
full absolute path. Since the cwd change happens after the cleanup,
removeItem silently failed to find the socket.

Add unit tests verifying controlSocketURL resolves correctly for both
absolute cleanup and relative binding use cases.

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.

Tart powers Cirrus Runners service — a drop-in replacement for the standard GitHub-hosted runners, offering 2-3 times better performance for a fraction of the price.

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