Command bundles

Bug Fixes

  • Multi commands run slowly #677
    • Optimized Relay's Docker integration:
      • Containers are cached and reused for the duration of a command pipeline. Doing so reduces worst case Docker container creation from O(N * I * R) to O(N * R) where N is the number of pipeline stages, I is the number of command invocations per stage, and R is the number of Relays able to run the command.
      • Implemented a custom streaming interface on top of Docker's hijacked connection API further reducing the number of Docker API calls required per command invocation.
    • Internal testing has shown these optimizations reduce execution times for Docker-based commands by 50 - 70%.
  • Fix Relay's JSON handling: Don't coerce large integers into scientific notation #768
  • HipChat can't execute Relay-mediated commands #770
