The buck rewrite has been available for a bit now at https://github.com/facebook/buck2 We've just publicly announced it today, you can read more here: https://engineering.fb.com/2023/04/06/open-source/buck2-open-source-large-scale-build-system/ The docs available at https://buck2.build/ also...

That graph just shows when most development moved over to the dev branch (#2401). For the dev branch, contributions tapered off much slower. But yeah, at this point development has...

Alternatively, is it like python's += (https://docs.python.org/3/reference/datamodel.html#object.__iadd__) where it's defined to first try using a type-specific in place add and falling back to normal addition if it's not supported? My...

I think this seems like a fine improvement. Right now buck.type comes from some internal data that probably can't be changed (as it's used to lookup the rule impl function...

Yep, you need it to be the default output of a target or subtarget. What kind of rule is `//:ext-link`? If it's a genrule, that already has support for adding...

I think we're going to try to improve this in the next several weeks. It's likely that even something fairly naive is going to be able to get most of...

I think a challenge here is that basically every action has inputs that are produced by other actions. You would need to find a way to canonicalize those as well,...

I had assumed you meant a model where the action sees its output with path 00000000000 but then it gets rewritten to the real path, because it keeping the 00000000...
