Bug 156939

This was discovered with the w3c platform test found here: http://w3c-test.org/IndexedDB/idbfactory_open9.htm

I can look into this soon if this helps

The generated bindings seem wrong here. They'll just convert undefined to 0. This will probably require tweaking the bindings generator and used Optional<> type for this parameter.

Retitling for clarity: Autogenerated IDBFactory.open() does the wrong thing if you pass an explicit 'undefined' as the second argument

(In reply to comment #3) > The generated bindings seem wrong here.

In fact, I *would* like to consolidate the multiple IDBFactory::open methods down to one. It seems silly that there's two just because of the optional argument. If the bindings get changed to pass Optional<> for the second argument, IDBFactory can + should adopt that.

I think we've identified the path forward, but just to clarify an earlier point: (In reply to comment #3) > The generated bindings seem wrong here. They'll just convert undefined to 0. Actually what they're doing is throwing a NaN exception because "undefined" is not a number in the expected range.

This should be the default behavior and we should have a flag such as DoNotUseWTFOptionalForParameters on interfaces that have not been ported yet. Note that when porting interfaces, we don't necessarily have to switch the implementation to use Optional<>. In most cases (but not the IDBFactory.open case), we can simply specify a default value in the IDL: e.g. [RaisesException] ScriptProcessorNode createScriptProcessor(unsigned long bufferSize, optional unsigned long numberOfInputChannels, optional unsigned long numberOfOutputChannels); would become [RaisesException] ScriptProcessorNode createScriptProcessor(unsigned long bufferSize, optional unsigned long numberOfInputChannels = 2, optional unsigned long numberOfOutputChannels = 2); and then the C++ implementation would stay unchanged since we only use WTF::Optional for parameters without a default value.

Comment on attachment 277135 [details] WIP patch View in context: https://bugs.webkit.org/attachment.cgi?id=277135&action=review Thanks for tackling this! Giving a review feedback comment to clarify where I thought this was heading: > Source/WebCore/Modules/indexeddb/IDBFactory.h:57 > RefPtr<IDBOpenDBRequest> open(ScriptExecutionContext&, const String& name, ExceptionCodeWithMessage&); > - RefPtr<IDBOpenDBRequest> open(ScriptExecutionContext&, const String& name, unsigned long long version, ExceptionCodeWithMessage&); > + RefPtr<IDBOpenDBRequest> open(ScriptExecutionContext&, const String& name, Optional<unsigned long long> version, ExceptionCodeWithMessage&); The new method signature: + RefPtr<IDBOpenDBRequest> open(ScriptExecutionContext&, const String& name, Optional<unsigned long long> version, ExceptionCodeWithMessage&); Seems great. But my understanding was that the new mechanism would completely obsolete the version of open() without the version argument. i.e., line 56 should be gone, and everything in the auto generated JSIDBFactoryOpenFunction would call the new line 57 version.

Yes, I haven't had time to experiment with this part yet but I will.

"to all parameter types" I don’t the comment is clear enough. The idea is that we want to remove all these exceptions from the list one by one and then remove the function entirely. But I don’t think the comment makes that clear. This also seems like something that might belong in CodeGenerator.pm rather than in the JS-specific one, even if we are only implementing in JavaScript for now. I am doing a similar project for enumerations, where future enumeration types will all use "enum class" in the C++ DOM but some are still using String for legacy reasons. In that case, I chose to put the function in CodeGenerator.pm and used a hash for the "black list". > Source/WebCore/bindings/scripts/CodeGeneratorJS.pm:3627 > + my $defaultValue = "Optional<" .
