Description Sander Hoentjen 2016-08-29 07:57:30 UTC
I have an issue with a strange kind of redirection. The webserver detects when a non-TLS connection is made to a TLS port, and reponds with a Location-header. It then seems to abruptly terminate the connection.

This works fine from a user-prespective in all the browsers I have tested: various (probably all) version of IE, Firefox, Chromium, Safari, elinks, curl. It doesn't work with epiphany.

Curl output:
~]$ curl -v -L

So this is probably a symptom rather than the underlying cause, but it's a great place to start. The question here is: is the assert wrong, or is it wrong that we bubble up some other type of error? This is not the first time we've hit this assert. I'll try to investigate (eventually).

The underlying bug is probably in WebKit or libsoup somewhere.
Comment 2 Sander Hoentjen 2016-08-29 13:38:43 UTC
If there is anything I can do to help, let me know. Just know that I am not a developer :)
Comment 3 Carlos Garcia Campos 2016-08-29 16:25:59 UTC
I haven't look at the problem in detail, but that assert has been wrong for some time, it doesn't cover all the cases, it needs to be checked again or simply removed.
Comment 4 Michael Catanzaro 2016-08-29 18:47:12 UTC
I removed the assert. Once you get a new build, you should see a proper error message to give us a hint what's going wrong here. Unfortunately I'm testing WebKit trunk which is broken ATM (crashes when displaying any page) so I won't check it myself right now.
Comment 5 Sander Hoentjen 2016-08-30 07:12:36 UTC
I build Fedora 24's epiphany with your patch. Now when I try the page it says:
Oops! Unable to display this website.
The site at “” seems to be unavailable. The precise error was:

Error receiving data: Connection reset by peer

It may be temporarily unavailable or moved to a new address. You may wish to verify that your internet connection is working correctly.
No output on the console this time.
