Clean up unused checkouts on dev-desktops #389
Conversation
User might checkout repositories on the dev-desktops, work on them for a while, and then move on to other projects. The unused checkouts, in particular their `build` or `target` directories, can use up a lot of space that we want to reclaim periodically. A script has been created that finds all cache directories, checks recursively if any file in their root directory has been modified within a given time frame, and if not deletes the cache directory.
A new cronjob has been created that looks for unused build artifacts and deletes them. The job runs every day at midnight.

You may also want to sweep build-rust-analyzer too, which is a secondary build dir recommended for r-a workflows: https://rustc-dev-guide.rust-lang.org/building/suggested.html#configuring-rust-analyzer-for-rustc

I'll make a note of this in #390, which tracks rewriting the script in Rust. I fear adding more conditions to the find command will get unmanageable quickly. 🙈

Great @jdno. I was wondering if on top of removing old builds, we shouldn't have certain amount of free space always ensured just in case some of us are creating new build and may run out of space. |
There are two separate issues that we want to handle differently, I think. First, we don't want to run out of disk space on the root partition |
