Description Sergio Villar Senin 2014-03-03 11:17:28 PST
As suggested by Darin in https://bugs.webkit.org/show_bug.cgi?id=128173#c2. The recommended alternative is static NeverDestroyed.

I removed the list of changes in the WebCore ChangeLog because it was huge
Comment 2 Sergio Villar Senin 2014-03-13 03:31:03 PDT
BTW I opened bug 130185 to start replacing them with static NeverDestroyed<T>

Did you use the do-webcore-rename script? It’s really good at doing changes like this one automatically.

> Source/WTF/wtf/StdLibExtras.h:38
> -#ifndef DEFINE_STATIC_LOCAL
> +#ifndef DEPRECATED_DEFINE_STATIC_LOCAL

Should update the comment above to talk about using NeverDestroyed instead.

> Tools/DumpRenderTree/JavaScriptThreading.cpp:49
> +    DEPRECATED_DEFINE_STATIC_LOCAL(Mutex, staticMutex, ());

Note for the future: I’m surprised we need this at all in test tools. A plain old static should be OK in all the test tool cases. It’s only the frameworks themselves that have the “no static destructor” constraint.

> Tools/Scripts/check-for-exit-time-destructors:100
> +    print "ERROR: Use DEPRECATED_DEFINE_STATIC_LOCAL from <wtf/StdLibExtras.h>\n";

This is no longer correct advice. The message should mention NeverDestroyed instead.

> Tools/TestWebKitAPI/Tests/WebKit2/SeccompFilters.cpp:45
> +DEPRECATED_DEFINE_STATIC_LOCAL(String, rootDir, (ASCIILiteral("/")));

Same thought here about test tools not needing this.

Oh, didn't know about it, I just cooked my own.

Good point

Yep, I'll open a bug for that.
