Xen project Mailing List

Hey Mindy, thanks a lot for your response :)

There's still a ton of work to be done converting libraries (1) to topkg and away from OASIS and (2) to use the Logs library instead of Console.log or printf.

I did a bit of digging[1] in the package universe, and here's a small list of libraries that are still have an `_oasis` present in their root directory. The `opam` package name is listed first, then the repository where it lives:

cstruct (https://github.com/mirage/ocaml-cstruct)
crunch (https://github.com/mirage/ocaml-crunch)
ipaddr (https://github.com/mirage/ocaml-ipaddr)
qcow-format (https://github.com/mirage/ocaml-qcow)
mirage-console-xen (https://github.com/mirage/mirage-console) (this repository has code for both the mirage-console-xen and mirage-console-unix packages)

Converting things to topkg from oasis generally involves removing a bunch of autogenerated code and adding a small amount of structure around the invocation of topkg. topkg has documentation at http://erratique.ch/software/topkg , including a "menagerie" of examples at http://erratique.ch/software/topkg/doc/Topkg.html#menagerie . It's helpful to know a small amount about ocamlbuild (the build system that _oasis was autogenerating code to manage, and which topkg provides a simpler interface to) -- some documentation is available at https://nicolaspouillard.fr/ocamlbuild/ocamlbuild-user-guide.html .

This is really helpful, I'll start reading about the two packagers. Is this [1] a good example of the changes needed for the transition? Also, I guess that after making the modifications I should be able to generate the package and maybe install it locally but, are there any additional checks/testing in order to be sure that all went fine?

Logging's just seen a lot of activity over the past weekend! Probably verbosemode and hannesm can speak more to what might be valuable to look at immediately.

Similarly, I think djs55 can speak better to what might make sense to look at alongside the "tiny vm for load testing" project.

Ok, thx for the pointers, I'll try to continue with them after I get my feet wet with topkg :)

Thanks a lot for reaching out to the list! We're happy to hear from you. :)

Thank you :)
