| Hm yes now I remember that point about how the file system targets are anonymous Python objects that you can pass around to functions. Are there any open source examples? I looked around the github account, but I mostly remember this tool https://github.com/stb-tester/apt2ostree I'd be interested in seeing the Python config and Ninja output, to see how it works. Right now it looks to me like the dependencies are more implicit than explicit, e.g. with your copen example --- The system I ended up with is more like Bazel, but it's not building containers, so it's a slightly different problem (although I guess Bazel can do that now too). But I'm interested in building containers incrementally without 'docker build'. I made some notes on #containers in the oilshell Zulip about incorrect incremental builds with docker build. It's also slow and has a bunch of ad hoc mechanisms to speed it up I like the apt lockfile idea definitely ... However I also have a bunch of other source tarballs and testdata files, that I might not want to check into git. How do you handle those -- put them in OSTree? Our config looks like this https://github.com/oilshell/oil/blob/master/core/NINJA_subgr... and there are other /NINJA_subgraph.py files. The library they all use is in build/ninja* of the same repo. Thanks for any details! |
