I would be grateful if this change could be verified, as I found that there are only writes and no reads of ctxId. I couldn't find the reason why it was added this way from the git history.

While this isn't actively used at this time, I wouldn't remove the context.WithValue call. It could prove to be useful in debugging

[tempora-mutantur]

Restored the calls as requested. Thank you.

After rebasing, I re-ran tests including the GH_TEST_AUTH_MODE=anonymous configuration. I found that the provider now requires either token or app_auth to be specified (e.g., via GITHUB_TOKEN environment variable). Without it, I get:

        Error: Invalid combination of arguments
        
          with provider["registry.terraform.io/hashicorp/github"],
          on terraform_plugin_test.tf line 2, in provider "github":
           2:           provider "github" {
        
        "token": one of `app_auth,token` must be specified

The issue appears to be caused by using ExactlyOneOf validation in the provider schema:

https://github.com/integrations/terraform-provider-github/blob/main/github/provider.go#L25

ExactlyOneOf requires that exactly one of the specified fields must be set, which prevents anonymous mode from working when neither token nor app_auth are set.

I tested the "can be configured to run anonymously" test case by removing the line

https://github.com/integrations/terraform-provider-github/blob/main/github/provider_test.go#L57

to test this

https://github.com/integrations/terraform-provider-github/blob/main/website/docs/index.html.markdown?plain=1#L32

It failed with: "app_auth": one of 'app_auth,token' must be specified

        Error: Invalid combination of arguments
        
          with provider["registry.terraform.io/hashicorp/github"],
          on terraform_plugin_test.tf line 2, in provider "github":
           2:           provider "github" {
        
        "token": one of `app_auth,token` must be specified

Maybe we could use ConflictsWith instead of ExactlyOneOf if we want to allow providers with no auth config.
