• Component: WebKit Misc.

[Tibor Mészáros]

It's a feature that everyone has enabled, so we should get rid of the guard?

Windows port doesn't enable blobs. I don't know why, perhaps it should. I'd certainly be super happy to have Blobs enabled unconditionally, it is very annoying and cofusing that some blob related code is enabled, and some is not.

> Source/WebCore/WebCore.exp.in:-2865
> -#if ENABLE(BLOB)
>  __ZN7WebCore12BlobRegistryD2Ev
>  __ZN7WebCore12blobRegistryEv
>  __ZN7WebCore14LoaderStrategy18createBlobRegistryEv
>  __ZTVN7WebCore12BlobRegistryE
>  __ZTVN7WebCore16BlobRegistryImplE
> -#endif

This file is alphabetically sorted, except for conditional exports. Could you please move these lines up to maintain the rule?

My comments about the previous version of the patch still apply.

This patch managed to solve the failing test problem.

Please fix the order problem mentioned by Alexey in Comment #10 , and fix the Windows build. You only need to export the necessary symbols with adding them to WebKit/WebKit.vcxproj/WebKitExportGenerator/WebKitExports.def.in .

I'm not sure why Windows port didn't enable BLOB before, but in this case
I suggest starting a conversation about it on webkit-dev. Or maybe we
should try to enable BLOB on Windows first and later remove the guards
if everything works fine.

Patch v4

Change to alphabetical order in Source/WebCore/WebCore.exp.in, and added symboles to fix win build

[Alexey Proskuryakov]

I'm confused - doesn't this patch already enable BLOB on Windows by removing the guards? If so, I'll need to find out how to approve it from Apple side.

Try to make EWS happy. Mac: Add __ZN7WebCore12blobRegistryEv to Source/WebCore/WebCore.exp.in; Windows: Add missing files to Source/WebCore/WebCore.vcxproj/WebCore.vcxproj; revert WebKitExports.def.in changes - I think it isn't necessary, adding missing files to vcxproj file should be enough

You're right, this patch enables BLOB on Windows with removing the guards,
that's why I mentioned in Comment #13: "maybe we should try to enable BLOB
on Windows first and later remove the guards if everything works fine."

But before doing anything (enable BLOB on Windows / remove guards )": Tibor,
please write a mail about it to webkit-dev to ask the opinion of the wider
WebKit community. Maybe there is a good reason why isn't BLOB enabled on Windows.

LGTM, r=me.

There weren't any objection on webkit-dev, so let's go ahead and land it.
