core: Strengthen how we enforce lockfiles One problem with how we use lockfiles right now is that we don't enforce them for dependencies. That is, if `foo` requires `bar`, but only `foo` is in the manifest, then while `foo` will be locked, `bar` will never be checked against the lockfile because it was never explicitly requested. Higher-level though, I don't like how indirect the locking here feels. See some comments about that in: https://github.com/projectatomic/rpm-ostree/pull/1745#discussion_r288772527 https://github.com/projectatomic/rpm-ostree/pull/1745#discussion_r289419017 Essentially, the manifest is an input file of patterns, and all we really know from the lockfile output is that the set of packages in there satisfies this input in some way. But: 1. there are multiple ways to satisfy the same input (hence why hints like `SOLVER_FAVOR` exist) 2. the solution is dependent on how the solver is implemented (i.e. different libsolv versions might yield different solutions) 3. the solution is dependent on flags fed to the solver (i.e. different libdnf versions might yield different solutions) So any attempt at cross-checking between the input file and the lockfile is going to be very hard. Using a stricter mode as I suggested in #1745 of only allowing pure pkgnames or NEVRAs would help, but it wouldn't address the dependency issue. (Though I'm still thinking about possibly doing this anyway.) The solution I propose here is instead to take the nuclear approach: we completely exclude from the sack all packages of the same name as packages in our lockfiles, but which do not match the NEVRA. Therefore, any possible solution has to also satisfy our lockfile (or error out). Closes: #1849 Approved by: cgwalters
