Nice experiment, but a bit expensive.
I work on Beagle, a git-compatible SCM [1]. I use ABC, Abstractionless C [2] dialect with slices, optional range checking, etc. So far, memory safety was the least of my concerns, frankly. Most of the thorny issues would be equally thorny in Rust (e.g. right now: reflog zeroed when VM ran out of disk space; must be some state machine issue or an OS level glitch). Also, forking off a C process (no runtime) is cheap enough that you actually want to do that more.
But, those are all technicalities. The key issue I see with the approach: the data structures and algos of git have been fanatically fine tuned for that particular application with those particular usage patterns. By very sophisticated low-level C programmers. So, quite likely, any other app/lib working with that store will always be a suboptima
Read the rest
l fit. I would recommend read-only access only, esp for LLM code.
Meanwhile, git's underlying data model (blobs/trees/commits) is very simple and very much internet-standard level. Decoupling at that interface is so much easier with so much less issues looming.
May look differently from your vantage point though.
