Bug 20274 – Assertion failure in ApplicationCacheGroup::addEntry when reloading a page with an application cache manifest

• Status: RESOLVED
• Resolution: FIXED
• Component: Page Loading

[Adam Roben (:aroben)]

I'm getting an assertion failure in ApplicationCacheGroup::addEntry when reloading a page with an application cache manifest.

1. Go to http://www.tknetwork.de/html5_und_apis/application-cache/application-cache.html
2. Hit Reload

Here's the assertion:

ASSERT(m_cacheBeingUpdated);

and the backtrace:

>	WebKit_debug.dll!WebCore::ApplicationCacheGroup::addEntry(const WebCore::String & url={...}, unsigned int type=4)  Line 652 + 0x2e bytes	C++
 	WebKit_debug.dll!WebCore::ApplicationCacheGroup::didFinishLoadingManifest()  Line 524 + 0x16 bytes	C++
 	WebKit_debug.dll!WebCore::ApplicationCacheGroup::didFinishLoading(WebCore::ResourceHandle * handle=0x07ec1d08)  Line 404	C++

This will lead to a crash in Release builds.
