Bug 105738 – Remove Key3 & Challenge Response from WebInspector-NetworkPanel-HeaderTab for websocket

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[pdeng6]

Since Key3 and Challenge response field are removed during IETF-websocket spec evolution, and corresponding interfaces are not invoked in current websocket implementation, I think remove them from web-inspector is reason-able.
@Toyoshima san, I guess they won't be back in future, am I right?

origin bug from https://code.google.com/p/chromium/issues/detail?id=142280

Yes. It's time to remove these obsolete fields.
Now that all WebKit ports migrate to the latest WebSocket protocol spec, RFC 6455, these fields are not used forever.

Could you clarify whether ports have migrated to the latest protocol? Any new fields need to be inspected? Why are these still in the WebCore APIs? I would imagine that when they are removed, inspector's code will get fixed automatically.

See https://bugs.webkit.org/show_bug.cgi?id=88620
hixie76 protocol related implementation should be deleted.

Hi pan,
Could you please delete Key3 related codes in WebCore also?

[Takashi Toyoshima]

Sorry, I missed the comment #6.

Yes, as Li said, old protocol doesn't work now, then all ports have no choice to use old protocol in WebKit.
Issue 88620 removed major parts of old protocol implementation. But it wasn't perfect.
Removing other hixie76 implementation looks fine.

Please git grep with 'useHixie76Protocol' in WebCore.
Also layout tests in http/tests/websocket/tests/hixie76 can be removed.

Deng:
If you don't  have a time to clean them up, please let me know. I'll do.

Thanks,

[pdeng6]

thanks, obsoleted fields in WebCore are removed in this patch, I think it is clean as my grep. :)

@tkent, @Pavel, could you please review this change?
