Validate event context key #5339

ffjlabo · 2024-11-14T08:08:56Z

What this PR does:

Added validation for event context key.

The event context is used as --trailer. The trailer key is currently allowed to use - alphabet, number, ' ', '\t' but it is unclear the actual format.
ref: https://github.com/git/git/blob/25b0f41288718625b18495de23cc066394c09a92/trailer.c#L630-L646

Also tried some formats below.

% git commit -m "Test" --trailer "github.repository: test" --trailer "github_repository: test" --trailer "github-repository: test"
% git show

    Test

    github.repository: test:
    github_repository: test:
    github-repository: test

So I added the restriction for the event context key format like kebab case such asTest-hoge test-hoge for now.

The pattern

OK (tried test-hoge)

% ./pipectl_v0.49.3_darwin_arm64 event register --address=localhost:8080 --api-key=xxx --name=simple --data="gcr.io/pipecd/helloworld:v0.40.0" --contexts="test-hoge=fuga" --insecure=true
Successfully registered event	{"id": "cc64b59d-82d1-4d3d-a669-b6051e9fe33b"}

Invalid key format (tried test.hoge)

% ./pipectl_v0.49.3_darwin_arm64 event register --address=localhost:8080 --api-key=xxx --name=simple --data="gcr.io/pipecd/helloworld:v0.40.0" --contexts="test.hoge=fuga" --insecure=true

Key is nothing

commented on regexp and nits.

IMHO, the error message like below is a bit confusing.
The validation error occurs at the key of the map, but the message says "value."

The regexp might be wrong.
The git implementations seem to allow double or more hyphens continuously like test--hoge or start with a hyphen like -test.
The pattern might be like ^[\-a-zA-Z0-9]+$.

@Warashi
Yes, I know that.
I don't plan to do the same as validation for git.
It is because the trailer format is not so concrete.

So I wanted to express the format like a kebab case test-hoge in PipeCD.

Okay, I got your point.

I see. Thank you for finding it. This is based on the code generated by protoc-gen-validate.
In my understanding, many validations are based on it.
Is there any idea?

How about implementing validations in pipectl code with go's regexp?
In my understanding, many parts of error messages from protoc-gen-validate will not be seen by users, but this is seen by users usually. So it's better that we can control the messages.

I got it. Sounds nice!
So we would accept the message on the server side and implement the validation in pipectl.

📝 It seems that these errors occurred when using pipectl.
e.g.

./pipectl_v0.49.3_darwin_arm64 event register --address=localhost:8080 --api-key=xxx --name=simple --data="gcr.io/pipecd/helloworld:v0.40.0" --labels="=fuga" --insecure=true

@Warashi Fixed in 179eef2

like this

go run cmd/pipectl/main.go event register --address=localhost:8080 --api-key=xxx --name=simple --data="gcr.io/pipecd/helloworld:v0.40.0" --contexts="test_hoge=fuga" --insecure=true
2024/11/14 18:32:34 failed to validate event context: invalid format key 'test_hoge', should be ^[a-zA-Z0-9]+(-[a-zA-Z0-9]+)*$
exit status 1

It also works OK pattern.

go run cmd/pipectl/main.go event register --address=localhost:8080 --api-key=xxx --name=simple --data="gcr.io/pipecd/helloworld:v0.40.0" --contexts="test-hoge=fuga" --insecure=true
