Bug #1178
closedCrash showing HTTP Authentication dialog when Browser is in background
0%
Description
When a page requests HTTP Basic Authentication, Privacy Browser crashes if the app does not have focus.
Obscure bug I know, but it is annoying losing tabs/work.
Stack trace attached.
Demo HTTP Auth URLs that trigger the user/pass dialog:
http://httpbin.org/basic-auth/testuser/testpass

I have pasted the output below.
To clarify, by not in focus I mean I have switched to another app entirely before the auth dialog is requested. Having a sufficiently slow connection might help reproduce. Httpbin.org doesn't appear to be behind Cloudflare so works with Tor.
Chrome (via Brave) and Firefox (via Tor Browser) appear to handle this situation by simply not showing the dialog and letting the page return a 401 Unauthorized response.

Looking closely at the logcat, it looks like this bug is similar to Bug #730: Crash when exiting settings if a proxy dialog is displayed.
Basically, the HTTP authentication code still runs after `onSaveInstanceState`, but it can't produce a dialog in that state.
`onSaveInstanceState` is not always run every time the app is in the background. It only happens when the system decides to recover RAM and kills the app (saving its state for future restoration).
The fix is the same as for #730, which involves delaying the display of the dialog until after the app is restored.
I should be able to include a fix in the next release.

I have prepared a debug build that I think resolves this problem. @Wade Paris, can you please test it out and let me know if it works?

The debug build can be install alongside your standard Privacy Browser. If it is helpful for testing, you can export your settings from the standard version and import them into the debug build.
