Description Brian Burg 2015-02-06 15:38:34 PST
There might be a mismatch in prefix keys between two WebPreferences instances.

Instance (1) is made by lazy initialization of WKWebViewConfiguration's WebPreferences, using prefix of "WebKit" (WKPreferences:init)
Instance (2) is made by the inspector WKWebView's WebPageGroup, using prefix of ".WebKit2" (WebPageGroup::WebPageGroup).

Both instances appear to read from NSUserDefaults. We manually set DeveloperExtrasEnabled on instance (1) before calling WKWebView:initWithFrame and that has the intended effect, so this instance is probably the one to worry about.
When stepping through WebPreferences::platformInitialize(), it seems that the if (!m_identifier) test fails, so only the debug preferences (enumerated by FOR_EACH_WEBKIT_DEBUG_PREFERENCE) are populated from user defaults.

Updated instructions at <https://trac.webkit.org/wiki/HackingWebInspector> to reflect new keys. However, we probably need to move the LogsPageMessagesToSystemConsoleEnabled key to the DEBUG group as well.
