Less automatic `build.rs` shenanigans #3814

emilk · 2023-10-11T15:24:58Z

Part of Fix unnecessary rebuilds by updating to maturin 1.3.1 #3266

What

`rust-analyzer` will no longer run codegen

…if you configure rust-analyzer to use --all-features, which you should, and which we do in .vscode/settings.json

Same is true for stuff like bacon too.

No build-time and git branch/commit for local developers

I've removed the build-time and git branch/commit from:

rerun --version
Viewer Rerun Menu -> About
analytics

for local developers (that means you), who has cloned our repository.

This is to save us from annoying re-builds using complex detection code.

No build-time and git branch/commit for crate users

Users of our crates (i.e. users who put rerun in their Cargo.toml or build rerun using cargo install rerun) will also no longer see the build-time and git branch/commit in these places. Previously we would try to get the git branch/commit hash for whatever folder they happened to be in (😬 ), which was not a great idea. So that's a bug fix.

The build time is a bit sadder to let go, but it was always unreliable: if you ran cargo update for instance, the build time would not update even if the rerun crate was being rebuilt. So instead of showing an unreliable built-time, I think it is better to just remove it.

I decided not to make these into environment variables right now. We can very easily do so now if we change our minds.

tradeoffs make sense to me. Good step forward to saner builds! Haven't tried it locally yet. Will stay in the lookout for spurious rebuilds etc.!

+        }


wouldn't it be more helpful to write something like built <unknown>?

Would it? Maybe "built at an unknown time", but then we could also add "and at an unknown place"

This is the output you get from rerun --version btw
