alt Hacker NewsIt’s insane. 45 minutes to build debug from scratch. Linking is super slow even in debug and that’s without LTO.
Incremental compilation is not cleaned up. Older deps pile up and don’t get cleaned.
Run out of disk space? Oh it’s just the 200+ GB codex-rs target folder.
Forget about doing worktrees.
Rust has a lot of work to do.

This is one of those problems that’s both huge/important, and probably impossible to solve. It bites me all the time, I have a measly 1TB nvme disk and I basically have to wipe my target directory and docker build cache (I have a shared cargo cache volume across builds) every other day. I’ve had this workstation for 2.5 years now and I’m honestly worried about nand endurance coming to bite me soon.
How would one even solve this? When do you know a cache entry won’t be used any more? Trace back provenance of artifacts to their sources, and if the mtimes have been bumped just delete the artifacts? It’s not like resetting source files to older mtimes is a good idea anyway…
