The macos_sdk module provides safe functions to access a semi-hermetic XCode installation.

Available only to Google-run bots.

class MacOSSDKApi(RecipeApi):

API for using OS X SDK distributed via CIPD.

  @contextmanager
— def __call__(self):

Sets up the XCode SDK environment.

This call is a no-op on non-Mac platforms.

This will deploy the helper tool and the XCode.app bundle at [START_DIR]/cache/macos_sdk.

To avoid machines rebuilding these on every run, set up a named cache in your cr-buildbucket.cfg file like:

caches: {
  # Cache for mac_toolchain tool and XCode.app
  name: "macos_sdk"
  path: "macos_sdk"
}

If you have builders which e.g. use a non-current SDK, you can give them a uniqely named cache:

caches: {
  # Cache for N-1 version mac_toolchain tool and XCode.app
  name: "macos_sdk_old"
  path: "macos_sdk"
}

Usage: with api.macos_sdk(): # sdk with mac build bits

Raises: StepFailure or InfraFailure.

  @property
— def host(self):

class WindowsSDKApi(RecipeApi):

API for using Windows SDK distributed via CIPD.

  @contextmanager
— def __call__(self):

Setups the Windows SDK environment.

This call is a no-op on non-Windows platforms.

Raises: StepFailure or InfraFailure.
