Clean up scratch space after solving

[davidschlegel]

Currently, I need to run many instances of the solver, each with slightly different parameters.
This causes the scratchspace to become large very quickly, creating files for the initial problem, the output, and configuration parameters. Is there a way to automatically clean up the scratch space where these files are stored to prevent them from becoming too large?

I think they should get automatically cleaned up when the Julia session ends. That doesn’t help if you’re solving many problems with a session though.

For that, one option is to manually clean it up; you can get the directory from a JuMP model with path = MOI.get(model, SDPAFamily.TemporaryDirectory()), and with Convex, the same thing except problem.model (only valid once the problem has been solved). Then you could delete it with rm(path; recursive=true).

Let me know if you have any issues.

We could also add an option to do this automatically as you said, but I’m not sure the best interface. If you’re interested, I think one way to do that would be to add a boolean immediate_ cleanup option to the Optimizer object, and then if that option is true, remove the tempdir here:

SDPAFamily.jl/src/MOI_wrapper.jl

Line 349 in 13210d3

end

. I’d be happy to review pull requests adding this feature.

Thanks for the feedback, let's see if this is a good workaround. It should be very easy to do it.
