Bump compiler dependencies

[clubby789]

#145849 (comment)
This manually downgrades the wasip/wit-bindgen/getrandom deps to avoid pulling in a binary blob, but it would be good to pin this automatically in a way which doesn't cause these blobs to be pulled in.

These commits modify the Cargo.lock file. Unintentional changes to Cargo.lock can be introduced when switching branches and rebasing PRs.

If this was unintentional then you should revert the changes before this PR is merged.
Otherwise, you can ignore this comment.

The list of allowed third-party dependencies may have been modified! You must ensure that any new dependencies have compatible licenses before merging.

If the Unicode version changes are intentional,
it should also be updated in the reference at

I'll open a reference PR for the Unicode change if this looks good

Backed out those changes in favour of #148321

Unsure what the status of this PR is

This manually downgrades the wasip/wit-bindgen/getrandom deps to avoid pulling in a binary blob, but it would be good to pin this automatically in a way which doesn't cause these blobs to be pulled in.

... Wait, does this only modify the lockfile? Can we explicitly pin those deps? Also, that seems a bit concerning, because if those deps release a point release for $bug, we won't be able to bump without introducing the binary blobs (if I'm understanding what you're saying) right?

Wait, does this only modify the lockfile? Can we explicitly pin those deps?

There's some discussion here. The relevant dep is 'pinned' in the tidy license checker (though this is complicated by the blob being moved to a different crate). The motivation for doing it like this vs a direct Cargo.toml dep is:

I couldn't figure out how to do this robustly. Cargo is designed to support multiple versions of the same dependency. We can lock a direct dependency but if a dependency of a dependency bumps the major wit-bindgen-rt version then I don't think we can protect against that using Cargo.toml alone. We'll just end up with multiple versions.

Added some pinning in Cargo.toml to try and avoid these bumps in cargo update, while leaving the pin in deps.rs.

cc @a1phyr (rust-lang/backtrace-rs#727 seems most likely to be the change causing this). Any idea why the ABI might be mismatched?

[clubby789]

microsoft/windows-rs#3741 / windows-link 0.2 removed the ABI overwriting behaviour, so backtrace-rs will need updating to account for that iiuc

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
