• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Antonio Gomes]

it tries to include JSSequence.h, which does not exist.

Hey Chris, I have a simple patch for this that basically just adds a further if check, and works find.

See https://gist.github.com/tonikitoo/ca92684ace9f226d8060

I am wondering if you have feedback and what is the way to test it (if any)? TestObj.idl?

Based on the comment above, the type needs to be an interface. I believe the check we really want is:
if ($codeGenerator->IsWrapperType($argType))

This is exclude native types, sequences, arrays, basically everything that is not a wrapper type.
Also note that there is another place in the script where the check needs to be updated.

Please add a test with an array as well.

Here is an updated patch. Chris, if you have any additional suggestion, please advice.

Otherwise, it should be good to land.

LGTM with a bit.

Ah, we fixed another bug :)

nit: It would be nice to add a method taking an array as well.

This broke bindings tests, <http://build.webkit.org/builders/Apple%20MountainLion%20Release%20WK1%20%28Tests%29/builds/13106/steps/bindings-generation-tests/logs/stdio>. Antonio, are you around to fix these now?

Hi ap. After looking at the failures, they are non-JS especific results that need rebaseline. I on propose only updated the JS ones, because I fixed a bug in CodeGeneratorJS.pm only.

(GObject seems to generated odd results)

So, if the policy just rebaseline all binding generator results, even if it is still broken (see below), I can do that.

Please advice.

It looks wrong, but possibly because the code generator is buggy.
