Hi, Sorry if this doesn't belong here, point me in the right direction if there is one ;) I read extensively what's there, and that is very helpful: https://pve.proxmox.com/wiki/Developer_Documentation I also read the thread here: I read also https://lists.proxmox.com/pipermail/pve-devel/2018-August/033448.html but that deals more with the repos than the actual dev env. Now I wonder, this all assumes you work directly on the test setup, patch and code from there, and I'm not a big fan of this, for many reasons… I usually do write code on my own station, that can access various test setups that I can spawn, be it in virtualbox, test installs of proxmox or nested ones for actual qemu tests. My question is, how do you guys do it, if there are any consensual setups? I wondered about different possibilities, tested some: - coding, versionning on a test environment: I don't like that: I need to maintain a test environment that includes the coding tools, and it will break, again and again, and not be in a reliable state, should I need to debug something. - compiling locally, having the debian and proxmox tooling, but that is not a happy solution, as I don't run Debian 10 or proxmox on my machine - using a set of hooks in git, mirroring stuff to a test instance, and compiling the packages there, rebooting as needed, that is easy enough, but I need to factor the dev environment - using a CI system to handle that on my branches/remotes, namely gitlab-ci with a runner on a pvetest instance, assetting the .debs, deploying them… that feels a bit overkill, but… well, I might like that more, but maybe we could have a lighter way there. So, if I'm dumb and there's an obvious choice, just tell me ;) If not, I'd love to hear about how you guys do it, and if we could make suggestions for that! Cheers, Gilou
