[gentoo-dev] [PATCH 1/3] python-utils-r1.eclass: Automatically enable '-p jobserver'

Show all headers | View raw

Automatically pass '-p jobserver' if running multiple jobs under
a jobserver, and dev-python/pytest-jobserver is intalled.  If it is not
installed, emit a warning since jobserver won't be respected.
