Bug 143334 – Remove unnecessary ASSERT from XMLDocumentParser::notifyFinished()

• Component: WebCore Misc.
• Status: RESOLVED CONFIGURATION CHANGED

[Gabor Rapcsanyi]

Remove the ASSERT(m_pendingScript->accessCount() > 0) because if the MemoryCache is disabled then we never icrease the accessCount.

Is it unnecessary, or incorrect?

Well, maybe incorrect is a better word for it. I'm not sure whether we should change the assert or just remove it.

Couldn't we have a layout test for this by exposing MemoryCache::setDisabled() via Internals?

Maybe ASSERT(m_pendingScript->accessCount() > 0 || MemoryCache::singleton().disabled()); then?

This patch has been pending review since 2015 with no recent activity.
It seems unlikely that it would even still apply to trunk in its current form.

Clearing from the review queue.

Feel free to update and resubmit if the patch is still relevant.

Seems like m_pendingScript is now changed to nullptr and it does not asset. Thanks!

There is no such assertion in XMLDocumentParser::notifyFinished any more.
