Doing so makes no sense. It seems like a no-op right now because we handle all the same cases first. But it's a hazard, and a problem for my upcoming patches.
This part replaces the JSContext *cx argument in most GC-related API
with JSRuntime *rt. When possible, the patch removes the code to obtain
a temporary cx just to run the GC.
The patch also removes JS_DestroyContextMaybeGC. That function is not
used in FF code base and its implementation is broken. It requires that
the context has an entered compartment when it is destroyed, which in
turns implies a missing leave compartment call.
This parts removes the usage of JSContext* during the finalization in
Web Workers and JS shells implementations. With this chnages JSContext * is only
accessed during the finalization in the SpiderMonkey implementation.
This part changes the signatures for various finalization API to take
not JSContext* but rather either JSFreeOp structure or its
library-private counterpart FreeOp. These structures wrap parameters
that are passed to the finalizers removing most of explicit dependencies
on JSContext in the finalization code.
In just 2 cases where JSPrincipals::codebase is used it can be reconstructed from the values stored in the associated nsJSPrincipal. In addition the patch makes nsJSprincipals to inherit both from nsIPrincipal and JSPrincipals allowing to use static_cast to convert between nsIPrincipal and JSPrincipals pointers and to drop many cases of manual JSPrincipal reference counting.
Use uint64_t where appropriate for mData, fails to build on OpenBSD
otherwise with wrong casts/no matching template.
