Just as with the old installer mechanism, our goal is that explicit provider installation is the only way that new provider versions can be selected. To achieve that, we conclude each call to EnsureProviderVersions by writing a selections lock file into the target directory. A later caller can then recall the selections from that file by calling SelectedPackages, which both ensures that it selects the same set of versions and also verifies that the checksums recorded by the installer still match. This new selections.json file has a different layout than our old plugins.json lock file. Not only does it use a different hashing algorithm than before, we also record explicitly which version of each provider was selected. In the old model, we'd repeat normal discovery when reloading the lock file and then fail with a confusing error message if discovery happened to select a different version, but now we'll be able to distinguish between a package that's gone missing since installation (which could previously have then selected a different available version) from a package that has been modified. |
