From 734a8a3100ae92d889932e83c186edad1cdb7b4d Mon Sep 17 00:00:00 2001 From: akutz Date: Tue, 3 May 2022 11:32:22 -0500 Subject: [PATCH] Cross-module support for filesystem paths This patch updates the controller-gen package loader to support loading packages across Go module boundaries for filesystem paths. What does this actually mean? Imagine a project with the following structure: my-project/ | |-- go.mod |-- go.sum | |-- apis/ | |-- v1alpha1/ | |-- go.mod |-- go.sum Prior to this patch, the following command, executed from the root of "my-project," would *not* include the package my-project/apis/v1alpha1: controller-gen crd \ paths=./apis/... \ crd:trivialVersions=true \ output:crd:dir=./config/crd/bases The reason the above command would not parse the types from the package my-project/apis/v1alpha1 is because it is a distinct Go module from the root module, where the command was executed. In fact, while the above command would silently fail to include those types, the following command will fail with an error: controller-gen crd \ paths=./apis/v1alpha1 \ crd:trivialVersions=true \ output:crd:dir=./config/crd/bases The above command fails because the underlying logic to load packages cannot load a path from one package when executed from the working directory of another package. With this patch, it is now possible for the first command to successfully traverse Go module boundaries for roots that are file- system paths ending with "..." with the following, high-level logic: 1. If no roots are provided then load the working directory and return early. 2. Otherwise sort the provided roots into two, distinct buckets: a. package/module names b. filesystem paths A filesystem path is distinguished from a Go package/module name by the same rules as followed by the "go" command. At a high level, a root is a filesystem path IFF it meets ANY of the following criteria: * is absolute * begins with . * begins with .. For more information please refer to the output of the command "go help packages". 3. Load the package/module roots as a single call to packages.Load. If there are no filesystem path roots then return early. 4. For filesystem path roots ending with "...", check to see if its descendants include any nested, Go modules. If so, add the directory that contains the nested Go module to the filesystem path roots. 5. Load the filesystem path roots and return the load packages for the package/module roots AND the filesystem path roots. --- pkg/loader/loader.go | 244 +++++++++++++++++++- pkg/loader/loader_suite_test.go | 29 +++ pkg/loader/loader_test.go | 191 +++++++++++++++ pkg/loader/testmod/dummy.go | 17 ++ pkg/loader/testmod/go.mod | 7 + pkg/loader/testmod/subdir1/dummy.go | 17 ++ pkg/loader/testmod/subdir1/subdir1/dummy.go | 17 ++ pkg/loader/testmod/subdir1/subdir2/dummy.go | 17 ++ pkg/loader/testmod/subdir1/submod1/dummy.go | 17 ++ pkg/loader/testmod/subdir1/submod1/go.mod | 3 + pkg/loader/testmod/submod1/dummy.go | 17 ++ pkg/loader/testmod/submod1/go.mod | 3 + pkg/loader/testmod/submod1/subdir1/dummy.go | 17 ++ 13 files changed, 590 insertions(+), 6 deletions(-) create mode 100644 pkg/loader/loader_suite_test.go create mode 100644 pkg/loader/loader_test.go create mode 100644 pkg/loader/testmod/dummy.go create mode 100644 pkg/loader/testmod/go.mod create mode 100644 pkg/loader/testmod/subdir1/dummy.go create mode 100644 pkg/loader/testmod/subdir1/subdir1/dummy.go create mode 100644 pkg/loader/testmod/subdir1/subdir2/dummy.go create mode 100644 pkg/loader/testmod/subdir1/submod1/dummy.go create mode 100644 pkg/loader/testmod/subdir1/submod1/go.mod create mode 100644 pkg/loader/testmod/submod1/dummy.go create mode 100644 pkg/loader/testmod/submod1/go.mod create mode 100644 pkg/loader/testmod/submod1/subdir1/dummy.go diff --git a/pkg/loader/loader.go b/pkg/loader/loader.go index 35c271335..064efa30f 100644 --- a/pkg/loader/loader.go +++ b/pkg/loader/loader.go @@ -1,5 +1,5 @@ /* -Copyright 2019 The Kubernetes Authors. +Copyright 2019-2022 The Kubernetes Authors.
