set CARGO_HOME correctly or stop using it
It looks like we set CARGO_HOME
incorrectly for invocations of both cargo build
and cargo test
. The cargo build
invocations work because we first cd
to the directory containing the .cargo
directory. The cargo test
invocations don't work for out-of-source-tree builds. #26455 (moved) contains a more minimal fix.
The setting of CARGO_HOME
is redundant if we cd
to the correct directory first. Or we could stop changing directories and instead set CARGO_HOME
correctly. We probably shouldn't do both because it's confusing and possibly inconsistent.
