Add remove-members helper tool implemented in go #2575

daemon1024 · 2021-03-15T17:37:19Z

Fixes #2052

This tool is implementation of the bash script in go with a few changes like using flags instead of environment variables

This currently resides in the hacks folder which I believe is not the right place, let me know where I should move this to and if it deserves it's own package

You will be prompted by a bot to use commands during the review process. Do not be afraid to follow the prompts! It is okay to experiment. Here is the bot commands documentation.

You can also check if kubernetes/org has its own contribution guidelines.

You may want to refer to our testing guide if you run into trouble with your tests not passing.

If you are having difficulty getting your pull request seen, please follow the recommended escalation practices. Also, for tips and tricks in the contribution process you may want to read the Kubernetes contributor cheat sheet. We want to make sure your contribution gets all the attention it needs!

Thank you, and welcome to Kubernetes. 😃

Hi @daemon1024. Thanks for your PR.

I'm waiting for a kubernetes 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.

@daemon1024 thanks for creating the PR for this!

Left some suggestions, but looks great overall! 🎉

Can you also add a test for this?

hack/remove-members.go

+
+//readMemberList reads the list of members to be removed from the given filepath
+func readMemberList(path string) ([]string, error) {
+	file, err := os.Open(path)


@mrbobbytables is the inactive member list a yaml file? how is that generated?

It's been a text file with 1 member per line. The list is generated from this sheet after some manual vetting: https://docs.google.com/spreadsheets/d/1jqxMOo9f1EG72i4sGE7g6RlNPvQ4_qfOx9K-UM4YsLw/edit

Thanks! One more follow up question - how does one generate this sheet?

Want to remove you as a single point of failure :)

The big stuff to regen it are in the notes tab in the sheet 👍 I thought it was owned/under the sig contribex shared dir, but it looks like I'm the only owner atm. I'll move it over in a bit.

hack/remove-members.go

nikhita · 2021-03-16T07:43:50Z

hack/remove-members.go

+	for _, member := range memberList {
+		var orgs, teams []string
+		count := 0
+		fmt.Print(member)


would be better to log here and a more descriptive log message

Should I change all instances of fmt to log?

Currently the output looks like

~/P/o/hack (remove-members-tool|…) ❯❯❯ go run remove-members.go -path=../config/kubernetes members.txt nikhita Orgs: [kubernetes] Teams: [sig-contributor-experience sig-release] Number of occurences: 3 Commit Command: "commit -m Remove nikhita from the kubernetes org -m Remove nikhita from sig-contributor-experience, sig-release teams" daemon1024 Orgs: [] Teams: [] Number of occurences: 0

P.s. I don't really want to remove you 😝 just for showing the output 😹

I think fmt is also ok, but would be good to use a more descriptive message :)

nikhita · 2021-03-16T07:45:59Z

hack/remove-members.go

+
+	re := regexp.MustCompile(`(\s+)?- ` + member + `(.*)?`)
+
+	if re.Match(content) {


we can probably count how many times member occurs in the path and return the count. This will ensure that count is accurate.

Do you mean to count the number of matches in the said file?

Do you mean to count the number of matches in the said file?

Yeah :)

Not a blocker for this, but potentially something in the future. We can marshal/unmarshal yaml while leaving the comments (go-yaml/yaml#132). This would also let us get team names directly.

@mrbobbytables -- I had a dig at this earlier by parsing the org files using k8s.io/test-infra/prow/config/org.Config, but there seemed to be something off there.

The processed org config when written back to disk had a lot of diff compared to the original file.

We can possibly dig deeper into it later.

It's been a bit since I looked at it , but potentially whitespace =/ since yaml supports some fuzzy inclusion:

foo: - bar

is the same as:

foo: - bar

Theres what people have written (both formats) and what go will want to format it as.

That as well. we may want to bite the bullet with a big initial diff as the subsequent updates should be deterministic .

One other thing was, in order to process comments, the structs in k8s.io/test-infra/prow/config/org.Config should have fields with yaml.Node as field type and then have post-processing helper method. I had taken a step back because of that complexity.

Yeah, what I'd probably do at that point is get away from editing by hand, and then have an add-member function or have a make command that ensures proper formatting before commit. Out of scope for this one though^^;;;

@mrbobbytables -- that's (adding members) what I was trying to automate. 😉

But, yes. Let's talk about this in a separate thread.

Adding to whitespaces and comments related changes, The substantial amount of diff is also created due to the difference in order of the yaml properties.
I was trying to parse the yaml files and removing members in a more structured way, I also faced this.

diff --git a/config/kubernetes-incubator/org.yaml b/config/kubernetes-incubator/org.yaml index baf4ca76..e2da8a87 100644 --- a/config/kubernetes-incubator/org.yaml +++ b/config/kubernetes-incubator/org.yaml @@ -1,10 +1,3 @@ -name: Kubernetes Incubator -description: Kubernetes Incubator -default_repository_permission: read -has_organization_projects: true -has_repository_projects: true -members_can_create_repositories: false -billing_email: [email protected] admins: - cblecker - fejta @@ -15,3 +8,10 @@ admins: - nikhita - spiffxp - thelinuxfoundation +billing_email: [email protected] +default_repository_permission: read +description: Kubernetes Incubator +has_organization_projects: true +has_repository_projects: true +members_can_create_repositories: false +name: Kubernetes Incubator

It seems to be sorting the fields.

I currently implemented this using kubernetes-sigs/yaml.

Can you also add a test for this?

Would it be fine to add some test .yaml files cause it wouldn't be right to perform tests on the actual files. Or should we work with TempFile

+
+func main() {
+	flag.StringVar(&configPath, "path", ".", "Path to config directory/subdirectory")
+	flag.BoolVar(&dryrun, "dryrun", true, "Enable Dryrun or not. This flag controls whether the changes are simulated or live. If the changes are simulated it will only print the removal details and the commit message")


@mrbobbytables for feedback on the help text

It could probably be simplified down to something like: Simulates changes to be applied and prints removal details

nikhita · 2021-03-16T11:36:50Z

hack/remove-members.go

+	flag.Parse()
+
+	flag.Usage = func() {
+		fmt.Fprintf(os.Stderr, "Usage: remove-members [flags] <file-containing-members-list>\n")


would be good to list out the flags here. http://courses.cms.caltech.edu/cs11/material/general/usage.html has some details on the format

Usage: remove-members [-dryrun] [-path] member-file (file-containing-members-list)

Is this fine?

+	for scanner.Scan() {

How about simplifying this using ioutil.ReadFile as used in removeMemberFromFile?

Note: ioutil.ReadFile has been deprecated in Go 1.16 although it shouldn't be a blocker since this repository still uses Go 1.13.

* use pflags * use iouyil instead of bufio for reading member list * preserve filemode after removals

daemon1024 · 2021-03-17T10:36:16Z

Should I move this to a new directory? ( helpers/remove-members maybe? )

Since I added an external package it seems to adding it to the go.mod at the root, I haven't committed it yet cause I am not sure if this a part of that or should I initiate a separate go.mod for this.
