| 9 // This test simulates the following situation: |
| 10 // 1. The browser process sends the navigation preload request to the server. |
| 11 // 2. In SW's FetchEvent handler: |
| 12 // 2.1 Executes GC with internals.collectGarbage(). |
| 13 // 2.2 Returns a dummy response "hello". |
| 14 // 3. The server sleeps 100 ms. So the browser process cancels the navigation |
| 15 // preload request when it recieves the response from the SW. |
| 16 // 4. Retry 1, 2 and 3 again. |
| 17 // Before https://crbug.com/702527#c9, |m_pendingPreloadFetchEvents| of |
| 18 // ServiceWorkerGlobalScopeProxy is accidentally cleared in the GC. So the SW |
| 19 // crashed when it receives the fetch event with preload request again in step 4 |
| 20 // while inserting the fetch into |m_pendingPreloadFetchEvents|. |
