Each nsCSSStyleSheet has a pointer to a nsCSSStyleSheetInner. The nsCSSStyleSheetInner is shared across multiple stylesheets, in general. The nsCSSStyleSheetInner owns the rules and the child stylesheets. What this means is that a given rule object is effectively owned by multiple sheets. However, cycles can only form through rule objects that have been JS-wrapped, and if we're JS-wrapping a rule object that means we have ensured that it's owned by only one stylesheet. Therefore, we only traverse and unlink mInner if it's uniquely owned by our sheet. Similarly, if our child sheets or any of their rules have been JS-wrapped, that means that we must have an mInner that we own outright. |
