courgette

For example, courgette shows up on the Chrome-only list, but a quick search suggests that it's Open Source.

This is why programs like bsdiff and courgette exist, because comparing binaries is actually an enormously non-trivial problem.

Yes Apple could save a lot of bandwidth by distributing the diffs or using courgette anything.

Google invented Courgette and Zucchini which partially decompile binaries then recompile them on the other end to reduce the size of diffs.

I was thinking the same when i saw Opera will be using Courgette for update too.

Yes, they were saying that bsdiff produces diffs 10x courgette.

Do I understand correctly you'd need to implement small updates with Courgette [1] yourself - aka it's on the Chrome side of things, not in Omaha?

Google courgette only does a disassembly.

Along with some roast carrots/courgette/aubergine.

[An extra tidbit- courgette is a 'summer squash'.

Chrome uses courgette, now if it actually became a standalone project that could be used outside of google (you need to jump through their frankly stupid build system) I'm sure it would see adoption.

I wonder if the ideas of Courgette and Zucchini can be incorporated into zsync's hashes so that you get the minimal diff, but the flexibility of not having a perfect previous version to work from.

Or courgette that wouldn't be satisfied by zuchini, or both of those by "baby marrow".

Courgette is very cool, but all it does is make updates smaller, which is only one part of making updates less annoying.

Courgette looks like a promising way to shrink those updates even further.

They were using BSDiff for Chrome updates before they switched to Courgette.
