Hmm, I was able to gut it out of the engine and put it into dutil. I haven't
pushed yet, but was wondering about the general feeling of passing untyped
pointers was.
Ex:
HRESULT DAPI WininetDownloadUrl(
__in LPVOID pData,
__in LPAUTHENTICATION_ROUTINE pAuthentication,
__in DOWNLOAD_CACHE_CALLBACK* pCallback,
__in DOWNLOAD_SOURCE* pDownloadSource,
__in DWORD64 dw64AuthoredDownloadSize,
__in LPCWSTR wzDestinationPath
);
The reason for the untyped pointer was the only thing that really cared about
it was the Authentication callback, so I abstracted that away and I'm allowing
the caller to define what context he needs for authentication. This allows the
engine to pass a pointer a struct containing the UX, and other IDs, while a BAF
can pass the information it cares about (and each have their own independent
auth routine). I also moved the structs needed and renamed them to not be burn
specific, and used typedefs in the engine to allow the BURN_* types to function.
With this setup, I am 99% of the way there where the engine changes originally
committed have been ported to a BAF. My final hold up is finding a clean way to
get the bundle version from the UX manifest. Was it an intentional decision to
not expose the UX manifest to the BA?

Subject: [WiX-devs] RFC: Download functionality
After today's triage, I'm looking to start a discussion on migrating the burn
engine's download functionality to balutil so that BA's can utilize the same
code without having to go through the engine.
After a speedy review, it looks like the amount of engine specific hooks is
limited to the UX window handle and an on error callback. If it is that simple
I may try migrating this myself.
Thanks,
Jacob
