Bug 80030 – [GObject bindings] Supplemental interfaces are not disabled with the "Conditional" attribute

• Status: RESOLVED
• Resolution: FIXED
• Component: WebCore Misc.

[Zan Dobersek]

This is a spin-off from bug #79375 that focuses on the titular problem in the GObject bindings only.

For instance, some distributions may compile WebKit with --disable-geolcation. Ideally, the GObject binding API should be the same in either case, even if the geolocation methods are stubs when disabled. The reason for this is that downstream applications need to be able to rely on certain API points being present to use them effectively.

This is a valid concern. Generating bindings for a feature that's not supported in Gtk port, regardless of that feature being enabled, doesn't really make sense and can backfire in the shape of confused users. Generating bindings unconditionally for features that are fully supported and are enabled by default in the Gtk port is not as radical, but again, it is possible that some distributions may ship the library with geolocation (or any other feature) support disabled, causing problems.

An alternative, as already mentioned, is to create new API for feature detection, an equivalent to the ENABLE macro, and use that.

[Zan Dobersek]

I've tried to fix this in two different ways mentioned, here's what came out of each:

1) Creating stubs when the feature is not enabled

This seemed to work well, making changes mostly to the CodeGeneratorGObject script. Additionally, when a future is not enabled, warnings could be thrown, telling the feature is not enabled.

For compilation without geolocation support enabled, with this approach, it would also probably make sense to convert methods in WebKitGeolocationPolicyDecision to stubs when necessary.

Using this approach might work better if there's a decision to push this into the 1.8 branch. There's no new API additions.

2) Create and use ENABLE-like macro

This would require something like a WEBKIT_HAS_FEATURE macro to be added. This macro would then be used in public headers, while implementation files could use ENABLE macro.

One problem that immediately popped out was that when geolocation is disabled, the documentation could not be properly created - if the feature is disabled, the  gtkdoc tools complain of undefined references to this feature's methods. I don't know if this is a showstopper, but it would definitely cause inconvenience to distributions that would like to ship the library with the documented feature disabled.


I'd like some consensus on what's the right approach so I can start working on a fix.

Using stubs sounds like a great approach. We definitely want this for 1.8.\

Does some refactoring in the CodeGeneratorGObject.pm and creates proper stubs in case feature is not enabled at compile-time. Also fixes the build when geolocation support is disabled.

Forgot to test this with a WebKit2 build, will update the patch later if there will be need.

There are style issues with the generated test bindings, which were probably showing even before this patch.

It's slightly hard for me to follow all of the changes to the code generator, but your approach seems reasonable and the generated files do look better.  Thanks for the patch!

This looks generally OK, but all the changes in the geolocation policy decision code seem pretty much unrelated? I think they should go in a different bug & patch, this is complicated enough to review as it is :) There also seems a couple of simple to fix style issues in the generated code that trigger warnings.

Yeah, this definitely makes sense.

NULL here?

And also here I suppose.

We might as well fix this double space while we are at it.

I'll also just put this into one line to avoid incorrect indentation.

I'm working on a patch that fixes all the style errors in the DOM bindings now. So, if you like, I can handle this.

Okay, that'd be great.

I'll be uploading a new patch with only changes to CodeGeneratorGObject.pm and rebaselines for the bindings tests.
