1034907 - Remove dangerous public destructor of dom::TimeRanges

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[Benoit Jacob [:bjacob] (mostly away)]

In bug 1028588 we removed dangerous public destructors of XPCOM-refcounted classes outside of a finite whitelist, see HasDangerousPublicDestructor. Now we are going over the entries in this whitelist.

One of them is: dom::TimeRanges

I've removed the public destructor of TimeRanges and updated affected uses accordingly.

Here are the results from the try server:

Looks good to me.  I'm going to forward the review to a DOM peer.

For a little change like this, it probably would have been enough to do a Linux64 debug-only try run.
