Expected:

Graceful expunging cache entries OR being able to distinguish between compiler versions as part of the key.

The missversioned files afterwards exist in the target/debug dir and unset RUSTC_WRAPPER does not solve the compilation, but makes a manual rm -rf target/debug necessary.

I believe this is a dupe of #87. Unfortunately sccache currently caches compiler information in memory in the server process using the compiler path and mtime as the key. When using rustup the rustc binary is a shim that selects the real compiler version to use and this shim very rarely changes so updating the underlying Rust toolchain will go unnoticed by sccache.

But that means, if i.e. redis is running in RLU mode and artefacts from compiler version A can indefinitely make the system corrupted / unusable while everybody already updated to version B.
I think it is rather common to have a set of developers with a non homogeneous set of compiler versions, all accessing the same cache.
Could be duplicate of #87 indeed.

I'm going to close this as a dup of #87. I agree that the underlying issue makes a shared compilation cache very difficult, but given that determining the actual underlying binary is hard, and the underlying binary isn't fixed because of toolchain overrides that crates can specify, I'm not sure how to fix it. Firefox has fixed it by resolving the "real" rustc prior to invoking cargo and ignoring toolchain overrides, but I understand that's not feasible for everybody.
