Done @jelbourn, although some of the CI builds are failing because of unrelated issues. (missing |
| .then((fixture) => { | ||
| fixture.detectChanges(); | ||
| let progressElement = getChildDebugElement(fixture.debugElement, 'md-progress-circle'); | ||
| expect(progressElement.componentInstance._interdeterminateInterval).toBeTruthy(); |

You can't access the private member here; The field either needs to be changed to /** @internal */ or we need some other proxy for checking that the interval has stopped.

Only remaining CI errors are lint |

It's updated to use a getter/setter on the interval and resetting it on the setter instead to avoid intervals stacking up. The CI is still throwing a Node ELIFECYCLE error, though. |
|
That node error message is just garbage that gets thrown when there's a tslint error. The actual problem is just above: |
| /** The id of the last requested animation. */ | ||
| private _lastAnimationId: number = 0; | ||
|
|
||
| /** The id of the indeterminate interval. */ | ||
| private _interdeterminateInterval: number; | ||
| get interdeterminateInterval() { |

This should be marked as /** @internal */

There we go. @jelbourn. EDIT: Regarding wrapping the tests in |
| /** The id of the indeterminate interval. */ | ||
| /** | ||
| * The id of the indeterminate interval. | ||
| * @internal |

The @internal actually goes on the public member rather than the private one; this tells TypeScript to omit the property when outputting a .d.ts file so that downstream users can't depend on it.

Sorry, I'm still not too familiar with all the ng2 concepts. It's updated now.
The indeterminate animation is based on an interval that keeps running, even after the element has been destroyed. This change cleans up when the element is destroyed. Also adds an extra null check for `performance.now`.
