Arvados

Summary: run-tests.sh --only install can leave the arvados gem in a half-installed state, where it appears in gem list but cannot be removed with gem uninstall, because its dependency arvados-google-api-client has been uninstalled out from under it. This causes test failures later.

Attached is a log of running the tool with bash -x. Here is the key bit that shows the problem happening:

+ gem_uninstall_if_exists arvados
+ gem list 'arvados$'
+ egrep '^\w'
arvados (3.1.0.dev20241203191210)
+ gem uninstall --force --all --executables arvados
ERROR:  While executing gem ... (Gem::InstallError)
    gem "arvados" is not installed

I've also attached a minimal reproduction script. It assumes that $WORKSPACE points to an arvados checkout where gems have already been built. It fails the same way:

$ bash -x gemtest.sh
…
+ gem_uninstall arvados-google-api-client
+ gem uninstall --force --all --executables arvados-google-api-client
Successfully uninstalled arvados-google-api-client-0.8.7.9
+ gem list '^arv'
