| // import-boss enforces import restrictions in a given repository. |
| // |
| // When a directory is verified, import-boss looks for a file called |
| // ".import-restrictions". If this file is not found, parent directories will be |
| // recursively searched. |
| // |
| // If an ".import-restrictions" file is found, then all imports of the package |
| // are checked against each "rule" in the file. A rule consists of three parts: |
| // * A SelectorRegexp, to select the import paths that the rule applies to. |
| // * A list of AllowedPrefixes |
| // * A list of ForbiddenPrefixes |
| // An import is allowed if it matches at least one allowed prefix and does not |
| // match any forbidden prefix. An example file looks like this: |
| // |
| // { |
| // "Rules": [ |
| // { |
| // "SelectorRegexp": "k8s[.]io", |
| // "AllowedPrefixes": [ |
| // "k8s.io/gengo/examples", |
| // "k8s.io/kubernetes/third_party" |
| // ], |
| // "ForbiddenPrefixes": [ |
| // "k8s.io/kubernetes/pkg/third_party/deprecated" |
| // ] |
| // }, |
| // { |
| // "SelectorRegexp": "^unsafe$", |
| // "AllowedPrefixes": [ |
| // ], |
| // "ForbiddenPrefixes": [ |
| // "" |
| // ] |
| // } |
| // ] |
| // } |
| // |
| // Note the second block explicitly matches the unsafe package, and forbids it |
| // ("" is a prefix of everything). |
