The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.
# The main substitution.

# Handle nsRefPtr.h itself, a couple places that define constructors
# from nsRefPtr, and code generators specially. We do this here, rather
# than indiscriminantly s/nsRefPtr/RefPtr/, because that would rename
# things like nsRefPtrHashtable.

/**
|
|
* This class will wrap a nsIRunnable and dispatch it to the main thread
|
|
* synchronously. This is different from nsIEventTarget.DISPATCH_SYNC:
|
|
* this class does not spin the event loop waiting for the event to be
|
|
* dispatched. This means that you don't risk reentrance from pending
|
|
* messages, but you must be sure that the target thread does not ever block
|
|
* on this thread, or else you will deadlock.
|
|
*
|
|
* Typical usage:
|
|
* RefPtr<SyncRunnable> sr = new SyncRunnable(new myrunnable...());
|
|
* sr->DispatchToThread(t);
|
|
*
|
|
* We also provide a convenience wrapper:
|
|
* SyncRunnable::DispatchToThread(new myrunnable...());
