Description

Summary

Trying to build Rust 1.95.0 using Rust 1.94.1, using vendored sources, fails due to:

+ python ./x.py dist
Building bootstrap
    Finished `dev` profile [unoptimized] target(s) in 0.43s
fatal: not a git repository (or any of the parent directories): .git
WARNING: The `change-id` is missing in the `bootstrap.toml`. This means that you will not be able to track the major changes made to the bootstrap configurations.
NOTE: to silence this warning, add `change-id = 148671` or `change-id = "ignore"` at the top of `bootstrap.toml`
Building stage1 compiler artifacts (stage0 -> stage1, x86_64-unknown-linux-gnu)
error: cannot update the lock file /build/rustc-1.95.0-src/Cargo.lock because --frozen was passed to prevent this
help: to generate the lock file without accessing the network, remove the --frozen flag and use --offline instead.
Build completed unsuccessfully in 0:00:01

Expected behaviour

This works with versions prior to 1.95.0, but stopped worked with this release.

Actual behaviour

See error above.

Bootstrap configuration (bootstrap.toml)

Research direction

Reproduce the failure with python ./x.py dist using the vendored sources and the shown configure options. Start by inspecting x.py, bootstrap.toml, .cargo/config.toml, and the handling of Cargo.lock; done means the Rust 1.95.0 tarball builds successfully with --enable-vendor without trying to update the lock file.
