Meta blobs

Posted Sep 26, 2026 7:54 UTC (Sat) by asayers (subscriber, #112356) \[Link\]

It is curious to me why nobody thought about inventing a "meta blob", i.e. an object much like a tree object, except that it stitches together a larger blob.

This is exactly what bup does. Sadly this useful idea never made its way upstream. The way bup implements it is backwards-compatible-ish: metablob-unaware git considers the repo valid, but incorrectly checks out any metablob as a directory tree.
