Is the existing PR from Team FireGiant still good to go? Or should we wait for a conclusion to this thread?

BVariantSetVariant() isn’t bad. Maybe, BVariantAssign()? I think the important trick is to control encryption state, right? Almost want a tri-state enum:

HRESULT BVariantAssign(

__in BURN_VARIANT* pTarget,

__in BURN_VARIANT* pSource,

__in BURN_VARIANT_ENCRYPTION state // unencrypted, encrypted, follow source

);

…or something like that.

Note2: Now that you mention it, I like it.

My original idea was to create a BVariantSetVariant(__in BURN_VARIANT* pVariant, __in BURN_VARIANT* pValue), but I scrapped it since it was almost an exact copy of BVariantCopy. Maybe that was the right way to go? I just wish I was right on the first pull request way back when :)

Hmm, I wonder if I introduced that inefficiency in the XML parsing? Hopefully not.

Note2: That's why I didn't submit it in a pull request :) I find it's much easier to talk about code changes when you can actually see it.

    Ahh, yes, right. The root issue is that the Source encryption
    state is rarely set “correctly”.  I 100% agree that using the
    target’s encryption state is weird. I guess what is needed is a
    “BVariantCopyEx()” (better name’s welcome) that is what you had
    originally to specify the final desired encryption state (i.e. you
    were right).

    I still stand by my comment though that the variables parsing from
    XML using variant as it does is pretty inefficient. <wink/>

    Note: the FireGiant change was the direct fix that was tested to
    unblock other processes happening here.

    Note2: The comment “// Encryption here (and decryption later
    inside BVariantCopy) could have been optimized away with breaking
    change.” is going look very strange over time. It’s much better
    for comments to explain why something was done vs. explaining that
    something that was not done could have been done. The latter will
    be very confusing (or frustrating) trying to figure out what the
    actual issue is. <smile/>
