Port open-vcdiff to C#

[jzebedee]

Google's open-vcdiff is the best open implementation of VCDIFF I've found so far. It's licensed under Apache 2.0 so there won't be any issues with the ported code. Porting it over should be the first step in making a working VCDIFF encoder, which nobody seems to have the stomach for yet. 😨

xdelta is the big dog in handling VCDIFF and xdelta3 has a few extensions to the format which help it along. I don't think we're going to get anything close to their performance, but it's the benchmark once we have a minimum working implementation.

What's the status? Are you still actively working on that? I really hope so, there's not a single good implementation for C# :-/

What's the status, too?

I never ported this, but others have. I'll look into rolling vcdiff into a later version.

• Metric completed a .NET port of open-vcdiff
• Ronny Chan updated and vectorized large parts of it into SnowflakePowered/vcdiff
