IIUC, these are all the canonical style for WTF.

It's really perplexing why GTK and WPE continue to have a problem here -- seems like the compiler doesn't understand namespace aliases: > In file included from ../../Source/WebCore/Modules/cache/DOMCacheEngine.h:34:0, > from ../../Source/WebCore/Modules/cache/CacheStorageConnection.h:29, > from ../../Source/WebCore/workers/WorkerGlobalScope.h:30, > from ../../Source/WebCore/inspector/InspectorInstrumentation.h:49, > from ../../Source/WebCore/dom/EventTarget.cpp:38, > from /home/ews/gtk-wk2-ews/WebKit/WebKitBuild/Release/DerivedSources/WebCore/unified-sources/UnifiedSource-be65d27a-8.cpp:5: > ../../Source/WebCore/platform/SharedBuffer.h:139:40: error: reference to ‘FileSystem’ is ambiguous > static Ref<DataSegment> create(FileSystem::MappedFileData&& data) { return adoptRef(*new DataSegment(WTFMove(data))); } > ^~~~~~~~~~ > In file included from ../../Source/WebCore/platform/SharedBuffer.h:30:0, > from ../../Source/WebCore/Modules/cache/DOMCacheEngine.h:34, > from ../../Source/WebCore/Modules/cache/CacheStorageConnection.h:29, > from ../../Source/WebCore/workers/WorkerGlobalScope.h:30, > from ../../Source/WebCore/inspector/InspectorInstrumentation.h:49, > from ../../Source/WebCore/dom/EventTarget.cpp:38, > from /home/ews/gtk-wk2-ews/WebKit/WebKitBuild/Release/DerivedSources/WebCore/unified-sources/UnifiedSource-be65d27a-8.cpp:5: > DerivedSources/ForwardingHeaders/wtf/FileSystem.h:226:39: note: candidates are: namespace FileSystem = WTF::WTF::FileSystem; > namespace FileSystem = WTF::FileSystem; > ^ > In file included from ../../Source/WebCore/platform/SharedBuffer.h:30:0, > from ../../Source/WebCore/Modules/cache/DOMCacheEngine.h:34, > from ../../Source/WebCore/Modules/cache/CacheStorageConnection.h:29, > from ../../Source/WebCore/workers/WorkerGlobalScope.h:30, > from ../../Source/WebCore/inspector/InspectorInstrumentation.h:49, > from ../../Source/WebCore/dom/EventTarget.cpp:38, > from /home/ews/gtk-wk2-ews/WebKit/WebKitBuild/Release/DerivedSources/WebCore/unified-sources/UnifiedSource-be65d27a-8.cpp:5: > DerivedSources/ForwardingHeaders/wtf/FileSystem.h:63:11: note: namespace WTF::FileSystem { } > namespace FileSystem { > ^~~~~~~~~~ EventTarget.cpp does have `using namespace WTF;` but removing it in the latest patch here didn't help. This isn't really surprising though, since it's sitting safely within the `namespace WebCore {}` block.

Ugh, it seems to be a bug in GCC 6 and 7: https://godbolt.org/z/-00gZR Not sure what to do about this. I guess for WTF::Unicode we don't use a namespace alias and instead sprinkle `using namespace WTF::Unicode;` all over the place... The other possibility is to remove `using namespace WTF;` throughout WebCore. If we do the latter, I suppose it would make sense to split it out as its own patch first.

I guess pleasing GCC 6 was as simple as renaming the inner namespace to FileSystemImpl, following the precedent here: https://github.com/WebKit/webkit/blob/master/Source/WTF/wtf/JSONValues.h#L45 Now if I could just figure out why this patch causes API test timeouts for WinCairo...

To me it seems like PAL is the right place for it. I like the idea moving FileSystem to WTF because JSC shell starts testing persistent bytecode cache which resides in the FileSystem anyway. https://trac.webkit.org/changeset/240255/webkit' If some functions can be shared, it is nice.

Awesome. :D We're also intending to use FileSystem for PlayStation port's JSC shell.

Hmm, do you think it's better to add them now, or should we wait until JSC actually consumes FileSystem?

Since the current patch is pleasing EWS and JSCOnly will require separate verification, I'll land this one now and handle the rest in a separate patch this morning. :)

Looks like the changes in https://trac.webkit.org/changeset/240437/webkit has caused an API failure on Mac Debug.
