I noticed that in pepper_message_filter, |name| is int32_t.
Is it intentional to be different?

And I think it is better to pass PP_TCPSocketFeature_Private directly.

[Wez, 2013/02/10 04:47:02]

No; I just followed the style of the UDP SetBoolSocketFeature implementation. 
Fixed.
I based this on the UDP SetSocketFeature implementation, which uses int32_t
here, but I've switched these to use the enum.

I didn't see that you have switched to enum. Have you uploaded the latest patch?

[Wez, 2013/02/12 18:45:21]

Yes; see PepperPluginDelegateImpl.  This SetBoolFeature() is called by
PepperMessageFilter w/ a uint32_t "name" received via IPC, so to switch this to
an enum would require duplicating knowledge of the valid values.

[yzshen1, 2013/02/13 08:07:14]

You could directly use the enum over IPC, and use it at the host side.
For example, see:
