Hi @abogdanov37. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Hi @abogdanov37
Thanks for your contribution!

I think looks good to me for your codebase.
I add a few comments. Please check that.

So, I think we need to add some tests that check to fix the problem.

Hi @koba1t! I have been add test for fileloader. Skip localizer and kusttarget because have no idea how to test override loader there. If you have any idea please share it I'll try to implement

It looks like redirect.com is owned by a company.
I understand this fakeHttpClient won't access the global internet, but I prefer to use a reserved example domain instead of something that someone else owns.

Ок. I'll fix it!

koba1t

Thank you for adding a test!

So, it looks like your test only checks that the location needs to redirect. I think it's preferable to add a check to ensure that redirect doesn't happen.

I think that another tests check behavior if redirect is not happened.

@@ -423,7 +423,12 @@ func (kt *KustTarget) accumulateResources(
 			if errors.Is(errF, load.ErrHTTP) {
 				return nil, errF
 			}
+			var redErr *load.RedirectionError
+			if errors.As(errF, &redErr) {
+				path = redErr.NewPath


I think this code is using redirect Location path directly.
I am worried that newPath will be used by no check.
like the redirected path requires redirecting more, or the redirected path is missing contents.

I investigated in these scenarious

new loader works only with directory and git repo because of that all checks will be done in common way in

kustomize/api/internal/loader/fileloader.go

Line 152 in cc9dd34

func (fl *FileLoader) New(path string) (ifc.Loader, error) {

If newPath will be a simple url in new loader it will be treated as directory and kustomize finish work with error in common way

If some redirects (301 to 309 http codes) will happen in loading process

kustomize/api/internal/loader/fileloader.go

Line 314 in cc9dd34

resp, err := hc.Get(path)

They will be processed by http client out of the box
Following this points I think that all possible checks have been done

Sorry, Maybe I explained it wrong.

The scenario I was concerned about that the redErr.NewPath address returning a 300 status code.

I have understood! Sorry ((( I does not implement this case to avoid recursion. If you think that this case should be implemented I'll do it.

Hi @abogdanov37
I'm so sorry to delay the review.

I add comments for implements. Please check and write your comment if you think my worries are trivial matter.

Maybe That is better to solve redirects here than return RedirectionError and a new path.

Hi! It does not work in all cases. For example if I return redirect to git. In that case httpClient has no credentials for download content

For example if I return redirect to git. In that case httpClient has no credentials for download content

Sorry, I couldn't understand about this sentence.
In my understanding, that repo uses the HTTPS protocol to download when HTTP redirects to git.

My explanation was not clear. Sorry for that. I'll try again.
Example
We get next url in resource section https://example.com/apps/app1?version=1.1.0
When kustomize (in build proccess) go to that url, it get Redirect 300 with newPath https://customgit.org/somegrop/project-app1.git?refs=1.1.0. The repository is PRIVATE.
In this case if we go to that git repo using httpClient we get page with ask for credential (((
But if we create a new loader kustomize will use console git which already have credentials and can clone repository
