Colin Walters	ec4387afba	internals: New unpack verb ... This is part of taking over from librpm. The most important high level goal is fully unprivilged operation. Right now we're basically starting to do what http://libguestfs.org/supermin.1.html does, except in C, and faster. There's no reason that `compose tree` should require privileges. However right now, things like `%post` scripts will want to run in the target root - so we'd have to require `linux-user-chroot`. Regardless of unprivileged operation though, another major thing we can do is use our control over the unpacking process to do a lot more sophisticated caching. We can build up a precise mapping of (rpm ENVR, file path, selinux label) -> object and avoid rechecksumming each time. And even for files that aren't known, we can parallelize commit with unpacking, etc. (Ok assuming treecompose-post won't mutate anything).	2016-01-12 10:22:43 -05:00
Colin Walters	b456badba3	Add testing-only internals subcommand ... I'd like to experiment with different things that end up reusing chunks of the rpm-ostree internals, such as libhif, the helpers we already have around RPM, etc. In this particular case I'm experimenting with unpacking/committing RPM packages as non-root. Eventually most of this should end up as internal private shared library, but it's convenient to have an ABI-unstable and hidden "internals" command to run things directly. This commit though just adds the scaffolding for "internals".	2016-01-11 23:06:27 -05:00
