Pants

constructing an engine should be relatively lightweight, with the exception of rule validation maybe? but that's proportional to the number of installed rules cc <@U066LC126>

seems like we’d need to hoist the relevant BinaryUtil and Native options into global options and then could just instantiate those in engine bootstrap as non-Subsystem instances (e.g. use `x()` vs  `x.Factory.create`)

then actually provide them as Subsystem instances later as part of Subsystem bootstrapping in the engine

can probably make `Native` a standalone non-subsystem thing since its just used for bootstrap afaict

Is it actually intended to be modifiable? Or is it a subsystem out of habit?

PS I’m traveling so forgive the idiosyncratic reply cadence

probably just subsystem out of habit at this point

binary_utils requires options... but afaik, we've never actually used the options.

...well. hm. people might have played with the root path.

binaries.baseurls seems pretty critical in a private repos pants.ini

wonder if it might make sense to build the native engine binary in the setup.py context vs distributing via binutil

then it’d be a hting ot be guaranteed to be there at the package/dist level

wouldn’t be as flexible in terms of replacing the bin at runtime as needed, but could probably build in an escape hatch for that

getting setup.py to build a rust bin could also be a bit hairy, but a pattern/lib for that would be generally useful

does that amount to having platform-specific pants builds?

we only distribute sdists for pants today anyway

so this would just require the native engine to be built at install time

we could put out pre-build wheels containing platform-specific binary builds

to make that process easier for ppl whos environments dont ‘just work’ etc

Anyway, it looks like converting options processing to the engine is far from straightforward…

not rock-solid looking, but seems to be on the right track.

what’s scoot? and/or where can I read about it? sorry, couldn’t find it on google :slightly_smiling_face:

<@U3NHXA0F2>, if what I’m thinking is correct, it’s internal to twitter

it’s currently “stealth mode OSS”, meaning we’re focusing on using/hardening it internally before engaging w/ the broader community but we hope it will eventually be as open as pants.

cool! I hadn’t realized it was open sourced
