This is a bit complicated due to https://bugs.webkit.org/show_bug.cgi?id=129979, but that change didn't really buy us anything so I'm basically going to be undoing it.

Created attachment 275585 [details] Patch v1

This patch dumps Blobs/Files to a temporary file on disk. That's it - nothing more. It's required for the actual IDB work going forward, but is a nice reviewable chunk by itself.

We can't just close source? Bizarrely yes, because captured arguments lose their const'ness, but closeFile expects an actual const int as its argument. > > Source/WebCore/platform/network/BlobRegistryImpl.cpp:235 > > + static auto& queue = WorkQueue::create("org.webkit.BlobUtility", WorkQueue::Type::Serial, WorkQueue::QOS::Background).leakRef(); > > NeverDestroyed.

Lots of calling the same thing on main thread. Will rework it into the scope guard.

Created attachment 275636 [details] Patch for landing v2 Patch for landing again... does style bot really prevent commit queue? That's BS, if so.

Going to let style bot complain, *then* mark cq+... just to try it.
