Bug 174930 – Using "auto <function()> -> returnType" breaks prepare-ChangeLog

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[JF Bastien]

From Brady:

I just noticed this tonight. When a change is made to one of these functions, prepare-ChangeLog doesn't log the functions that changed.

I have a question and a request.

Question:

The functions in question where I noticed this:
auto WebURLSchemeTask::didComplete(const ResourceError& error) -> ExceptionType

Would normally be written as:
WebURLSchemeTask::ExceptionType WebURLSchemeTask::didComplete(const ResourceError& error)

Is there some actual value to using this syntax other than… being syntactically different, and being just a little shorter?

Request:

Until we fix prepare-ChangeLog, and unless there is some great advantage to this syntax that I'm not aware of… it's hold off on using it more.

Pardon my perl.

"unit tests"? What are those? ;-)

While I'm here, I also added const and volatile overloads.
