Powershell for the win
I am getting closer to supporting windows builds. I started to write two Powershell scripts, that will eventually perform the windows builds on the slaves: https://github.com/r-hub/wincheck
The first one run.ps1
- creates a new user with a random username,
- creates its home directory as well,
- makes sure that the home directory is not readable by other users,
- starts the build process (other script) as the newly created user, and makes sure that its standard output and error are redirected and still printed to the screen.
The other script is slave.ps1. This runs the actual R CMD check. It all works now, but I need more features, e.g. installing dependencies. In general it should do everything the unix version (at https://github.com/r-hub/rhub-backend/blob/master/templates/jenkins.sh) does.
Eventually these powershell scripts should go in the rhub-backend repository I believe.
Somewhat surprisingly, Powershell is not very good at some sysadmin tasks, e.g. creating local users is hard in plain Powershell. So for this we require Carbon (http://get-carbon.org/) for now, this has to be installed on the Windows builders.
