Re: CI for ray

Hello all,

Graham, thank you for your advice and those examples. It really makes sense to get rid of ssh dependency for a whole package, since it could be used on the same host.

Andreas, I removed ssh from dependencies and added mention by Graham line to the run-unit-test.

Regards, Nadiya

I recall this seeing this message in other packages in debian-science
and debichem. An alternate solution would be to add the following
line near the beginning of debian/tests/run-unit-test:

export OMPI_MCA_plm_rsh_agent=/bin/false

I believe that ssh is only required when MPI processes execute on
different hosts. It should not be required when the MPI processes all
execute on the same host, like a buildd or a CI tester.

codesearch.debian.net has many examples:
https://codesearch.debian.net/search?q=path%3Adebian%2F*+OMPI_MCA_plm_rsh_agent
and more specifically for autopkgtests:
https://codesearch.debian.net/search?q=path%3Adebian%2Ftests%2F*+OMPI_MCA_plm_rsh_agent
