A general conversion code -// generation task involves three sets of packages: (1) a set of -// packages containing internal types, (2) a single package containing -// the external types, and (3) a single destination package (i.e., -// where the generated conversion functions go, and where the -// developer-authored conversion functions are). The packages -// containing the internal types play the role known as "peer -// packages" in the general code-generation framework of Kubernetes. -// -// For each conversion task, `conversion-gen` will generate functions -// that efficiently convert between same-name types in the two -// (internal, external) packages. The generated functions include -// ones named -// -// autoConvert___To__ -// -// for each such pair of types --- both with (pkg1,pkg2) = -// (internal,external) and (pkg1,pkg2) = (external,internal). The -// generated conversion functions recurse on the structure of the data -// types. For structs, source and destination fields are matched up -// according to name; if a source field has no corresponding -// destination or there is a fundamental mismatch in the type of the -// field then the generated autoConvert_... function has just a -// warning comment about that field. The generated conversion -// functions use standard value assignment wherever possible. For -// compound types, the generated conversion functions call the -// `Convert...` functions for the subsidiary types. -// -// For each pair of types `conversion-gen` will also generate a -// function named -// -// Convert___To__ -// -// if both of two conditions are met: (1) the destination package does -// not contain a function of that name in a non-generated file and (2) -// the generation of the corresponding autoConvert_... function did -// not run into trouble with a missing or fundamentally differently -// typed field. A generated Convert_... function simply calls the -// corresponding `autoConvert...` function. `conversion_gen` also -// generates a function that updates a given `runtime.Scheme` by -// registering all the Convert_... functions found and generated. -// Thus developers can override the generated behavior for selected -// type pairs by putting the desired Convert_... functions in -// non-generated files. Further, developers are practically required -// to override the generated behavior when there are missing or -// fundamentally differently typed fields. -// -// `conversion-gen` will scan its `--input-dirs`, looking at the -// package defined in each of those directories for comment tags that -// define a conversion code generation task. A package requests -// conversion code generation by including one or more comment in the -// package's `doc.go` file (currently anywhere in that file is -// acceptable, but the recommended location is above the `package` -// statement), of the form: -// -// // +k8s:conversion-gen= -// -// This introduces a conversion task, for which the destination -// package is the one containing the file with the tag and the tag -// identifies a package containing internal types.

There are a number of `.import-restrictions` files that in the [k/k](https://github.com/kubernetes/kubernetes) repository, all of which are defined in `YAML` (or `JSON`) format. - -## How does it work? - -- When a directory is verified, `import-boss` looks for a file called `.import-restrictions`. If this file is not found, `import-boss` will go up to the parent directory until it finds this `.import-restrictions` file. - -- Adding `.import-restrictions` files does not add them to CI runs. They need to be explicitly added to `hack/verify-import-boss.sh`. Once an `.import-restrictions` file is added, all of the sub-packages of this file's directory are added as well. - -### What are Rules? - -- 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 prefixes. An example `.import-restrictions` file looks like this: - -```json -{ - "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": [ - "" - ] - } - ] -} -``` -- Take note of `"SelectorRegexp": "k8s[.]io"` in the first block. This specifies that we are applying these rules to the `"k8s.io"` import path. -- The second block explicitly matches the "unsafe" package, and forbids it ("" is a prefix of everything). - -### What are Inverse Rules? - -- In contrast to non-inverse rules, which are defined in importing packages, inverse rules are defined in imported packages. - -- Inverse rules allow for fine-grained import restrictions for "private packages" where we don't want to spread use inside of [kubernetes/kubernetes](https://github.com/kubernetes/kubernetes). - -- If an `.import-restrictions` file is found, then all imports of the package are checked against each `inverse rule` in the file. This check will continue, climbing up the directory tree, until a match is found and accepted. - -- Inverse rules also have a boolean `transitive` option. When this option is true, the import rule is also applied to `transitive` imports. - - `transitive` imports are dependencies not directly depended on by the code, but are needed to run the application.
