Codeville also used a weave for storage and merge, a concept that originated with SCCS (and thence into Teamware and BitKeeper).

Codeville predates the introduction of CRDTs by almost a decade, and at least on the face of it the two concepts seem like a natural fit.

It was always kind of difficult to argue that weaves produced unambiguously better merge results (and more limited conflicts) than the more heuristically driven approaches of git, Mercurial, et al, because the edit histories required to produce test cases were difficult (at least for me) to reason about.

I like that Bram hasn’t let go of the problem, and is still trying out new ideas in the space.

Pijul happened and it has hundreds - perhaps thousands - of hours of real expert developer's toil put in it.

Not that Bram is not one of those, but the post reads like you all know what.

I assume the proposed system addresses it somehow but I don't see it in my quick read of this.
