Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @alexcrichton (or someone else) soon.

Please see the contribution instructions for more information.

Thanks for the PR for this! I think there's also some documentation in src/doc which may need updating as well.

Given that this is somewhat of a major feature as well I think I would personally prefer to err on the side of placing this behind a feature gate to start with. Others on the team may feel differently though!

I think it would be good to also talk about how this works with rustdocflags. If there are flags that are required for correctness, then cargo test --doc would fail. I'm not suggesting that this should add rustdocflags, though. Just to consider what the impact will be.

I'm a little nervous adding this, as it is a very low-level thing which we haven't exposed in Cargo.toml before. One of my biggest concerns is that it can cause backward-compatibility hazards. For example, when Cargo adds new features or changes the way it invokes rustc, that can interfere with pre-existing flags. In a sense, this seems to be an end-run around Cargo not exposing the workflows that users want.

I'm not concerned enough to block it, as I can see its utility. However, I think we should tread very carefully.

alexcrichton · 2021-12-21T15:25:43Z

I share many of @ehuss's concerns as well, which is primarily why I'd like to see this feature-gated to start off with.

joshtriplett · 2021-12-24T08:36:09Z

I agree that this needs a feature-gate initially.

alexcrichton

Can you add a test that this is unstable?

Additionally I think that support also needs to be added for CARGO_PROFILE_RELEASE_RUSTFLAGS=... by configuring profiles via env vars.

☔ The latest upstream changes (presumably #10088) made this pull request unmergeable. Please resolve the merge conflicts.

zhamlin · 2022-01-05T14:13:59Z

Thanks for the review.

Fixed the issues you mentioned and added a test to verify passing rustflags via CARGO_PROFILE_RELEASE_RUSTFLAGS, it appears to be working without any additional code changes.

alexcrichton · 2022-01-05T15:26:39Z

Looks good to me, thanks! I'd like to double-check though that others are ok merging this as well (note that this implementation is gated behind a cargo feature)

I was a little concerned about the large number of new clone() calls, but in some rough benchmarking it doesn't seem to have much of an impact.
