Bug 250734 – [WPE][GTK] Cannot interact with github.com: the server responded with a status of 422 (Unprocessable Entity)

• Status: RESOLVED
• Resolution: MOVED
• Component: WebKitGTK

[Michael Catanzaro]

Since updating to WebKitGTK 2.39.4, it's no longer possible to interact with github.com using Ephy Tech Preview. I cannot post comments, change notification settings, etc. I see errors in the web inspector:

[Error] Failed to load resource: the server responded with a status of 422 (Unprocessable Entity) (comment, line 0)

This will make WebKit development quite inconvenient.

I can't reproduce.

I was hoping to bisect it, but I couldn't reproduce in my development environment, so I cleared all my website data for github.com and now the problem is gone. I'm still really suspicious because I've never seen this happen before until immediately after I upgraded to 2.39.4, but let's close this for now....

[Michael Catanzaro]

Two hours later, github.com is broken again, so reopening. This time I'll clear only one class of website data at a time until I figure out what is to blame. I'll start with cookies.

[Michael Catanzaro]

I deleted only the "user_session" cookie, signed in to GitHub again, and the problem is gone. Hm.

I've been doing this roughly 2-4x per day. Is it really just me...?

[Michael Catanzaro]

So this is not caused by WebKitGTK 2.39.4, but by a libsoup change that coincidentally landed in the same runtime update. That's pretty unlucky timing.
