Bug 113294 – REGRESSION(r145279): Build fails while linking when MEDIA_STREAM is enabled

• Component: WebKit API
• Status: RESOLVED FIXED

[Carlos Garcia Campos]

Due to undefined references to WebCore::JSRTCStatsResponse::nameGetter and WebCore::JSRTCStatsResponse::canGetItemsForName. In r145279 NamedGetter extended attribute is added to RTCStatsResponse.idl which makes the code generator to add prototypes for JSRTCStatsResponse::nameGetter and JSRTCStatsResponse::canGetItemsForName to the generated JSRTCStatsResponse header, but they are not implemented anywhere. We need to provide a SRTCStatsResponseCustom file with the implementation of both functions.

It seems JSRTCStatsResponse.h is not generated when media stream is disabled, so I guess I just need to move the include inside the #if ENABLE(MEDIA_STREAM) block

Could someone from qt confirm this? Maybe I should not include the JSRTCStatsResponseCustom.cpp file to the compilation for qt.

Patch seems clean to me, but seems to address a symptom, not the cause.

Does this mean that the [NamedGetter] modifier can only be used with custom bindings for JSC?

If so, that seems like a problem with the implementation of NamedGetter.

Are there test cases one could build for this, so that it gets detected earlier (either add NamedGetter to the test set for the JSC compiler, or add a target that compiles MediaStream with JSC and runs on the bots)?

I seems so, see all other JS*Custom files in bindings/js/

Since this is a build fix I think it makes sense to push it now. I agree that possibly the bindings generator should cope with this somehow (but I'm not an expert, so perhaps there are good reasons for this), but we can fix it after this patch lands. Also a BlackBerry EWS/buildbot is planned, so we should be able to catch this stuff in the near future.
