It proved to be unmaintainable due to the following reasons:
- determining upstream branch for the technology preview was a manual
and tedious process
- once determined, actual Safari Technology Preview occasionally
diverted from the branch
This is a speculative fix that moves "background pages cleanup"
to `_didCloseInternal` so that it is only run once, but on both
context closure and browser closure.
Symptom from a flaky test:
```log
browserContext.close: page@18087c372d32819222707ca5e8fd1030 is sending "close" event after being disposed
at PageDispatcher._dispatchEvent (D:\a\playwright\playwright\src\dispatchers\dispatcher.ts:86:15)
at Page.<anonymous> (D:\a\playwright\playwright\src\dispatchers\pageDispatcher.ts:59:12)
at Page.emit (events.js:314:20)
at Page._didClose (D:\a\playwright\playwright\src\server\page.ts:220:10)
at CRPage.didClose (D:\a\playwright\playwright\src\server\chromium\crPage.ts:165:16)
at CRBrowserContext._onClosePersistent (D:\a\playwright\playwright\src\server\chromium\crBrowser.ts:476:24)
at CRBrowserContext.close (D:\a\playwright\playwright\src\server\browserContext.ts:288:20)
```
When new page turns into download, we can have `_markAsError` followed
by the `Page.ready` signal and report the page twice (as an error and
as a real page). This is flaky and depends on whether `Page.ready` is
fast enough before the page closes or not.
Exposed by the "should report new window downloads" test.
This is exposed by the flaky "should report new window downloads" test.
In this test a new page is created, initialized and closed before initialization
finishes. If `lifecycleEventsEnabled` fails with "Target closed error",
we correctly ignore the initialization failure, but a single usage of the
failed promise with `.then` fails anyway.
This patch:
- rolls Firefox to v1269 which is now a firefox-stable build.
- introduces a new channel, `firefox-beta`, for our internal needs.
Fixes#6817
This reverts commit a25b11659be8887b700311180fcd3653aa9e472b.
In a discussion with Dmitry Gozman we decided to revert this and instead
proceed with the following approach:
- rename `//browser_patches/firefox` to `//browser_patches/firefox-beta`
- rename `//browser_patches/firefox-stable` folder to
`//browser_patches/firefox`
In all of the folders, we will keep the `BUILD_NUMBER` original so that
it doesn't clash on the CDN.
This patch:
- starts downloading Firefox Stable equivalent by default
- starts running Firefox-Stable on our smoke tests (tests-1)
- starts running Firefox-Beta on our CQ1 tests (tests-2)
Note: there's a little confusion right now with browser names:
- `firefox-stable` - firefox-stable equivalent
- `firefox`- firefox-beta equivalent
I'll rename `firefox` to `firefox-beta` in a follow-up.
Fixes#6817
