The metadata.error change was brought back in
https://github.com/microsoft/playwright/pull/29271and it broke java port
as we could have error and result set simulteniously. This PR moves the
logic to the trace recorder instead and keeps the protocol contract
clear that either error or result is present, but not both.
We stopped catching all exceptions in
https://github.com/microsoft/playwright/pull/28539 in hope that we'll
get loadingFailed even before Fetch.continue/fulfill command's error.
Turns out this is racy and may fail if the test cancels the request
while we are continuing it. The following test could in theory reproduce
it if stars align and the timing is good:
```js
it('page.continue on canceled request', async ({ page }) => {
let resolveRoute;
const routePromise = new Promise<Route>(f => resolveRoute = f);
await page.route('http://test.com/x', resolveRoute);
const evalPromise = page.evaluate(async () => {
const abortController = new AbortController();
(window as any).abortController = abortController;
return fetch('http://test.com/x', { signal: abortController.signal }).catch(e => 'cancelled');
});
const route = await routePromise;
void page.evaluate(() => (window as any).abortController.abort());
await new Promise(f => setTimeout(f, 10));
await route.continue();
const req = await evalPromise;
expect(req).toBe('cancelled');
});
```
Fixes https://github.com/microsoft/playwright/issues/29123
Motivation: On Windows we call around 50 times `PrintDeps.exe` which
takes on a very fast machine 500+ms. On Linux we do it around 120 times
(`ldd`) which takes around 150ms.
This change validates the dependencies once on browser install (`npx
playwright install`). In case its failing, it will emit a warning, in
case of a success, it will create a marker file that the binary has been
validated. For future `launch()` calls, we'll read this file and if
exists, we'll not validate again. Otherwise we'll validate again.
Note: If the marker file is older than 30 days, the browser will be
validated again.
This will now yield:
```

Error: ERROR: Playwright does not support chromium on ubuntu18.04-x64

On Ubuntu 18.04.
Previously, new `Recorder` instance was given an existing
`InjectedScript`. However, we built a separate source for
`InjectedScript` vs `Recorder`, and both bundles contain their own copy
of all helper modules, e.g. `roleUtils`.
This resulted in two copies of helper modules, which is troublesome for
any module-level globals like a top-level cache. Depending on whether
`Recorder` or `InjectedScript` called into the helper, they would access
the different value of a module global, which lead to bugs.
To prevent this, we force any external dependencies to be imported
through the `InjectedScript.utils`.
