@vflaux @mrozentsvayg Any comment on this PR ? Do you think you can review it ?

provider/cloudflare/cloudflare.go

+	if strings.Contains(errStr, "exceeded available rate limit retries") ||
+		strings.Contains(errStr, "rate limit") ||
+		strings.Contains(errStr, "429") {


I think we should handle this according to the doc here: https://github.com/cloudflare/cloudflare-go?tab=readme-ov-file#errors

var apierr *cloudflare.Error if errors.As(err, &apierr) { if apierr.StatusCode == http.StatusTooManyRequests { } }

This was implemented

so why do we have this code here?

Rate limit errors are not returned as ErrorTypeRateLimit cloudflare/cloudflare-go#4155 talks about the v0 version of the library which we don't use after merging your PR.

the first string.Contains is not needed if you have the second one.

Sorry forgot to commit it. It's gone now

…Flare API - Change CustomHostnames method signature to return autoPager[CustomHostnameListResponse] instead of processed []CustomHostname for better API matching and testability - Keep listAllCustomHostnames helper function for callers that need processed results - Update mock implementation to return autoPager with realistic CloudFlare API behavior - All tests continue to pass with improved interface design Addresses PR feedback about method signatures being closer to CloudFlare API for better mocking.

- Handle CloudFlare v5 SDK errors according to official documentation - Use errors.As() to check for cloudflare.Error type - Convert 429 (rate limit) status codes to SoftError for retry logic - Add comprehensive test coverage for v5 error handling - Use wrapper types in tests to avoid CloudFlare SDK internal nil pointer issues Addresses PR comment on line 376 requesting proper v5 error handling.

@vflaux everything look good now?

I've not review all the new tests yet.
Looks like IA generated, some clearly improve test coverage, others seems less relevant. 😄

The tests just fail because of rate limits to coveralls

Did you @AndrewCharlesHay address comments by @vflaux ?

Cleaning up things that are not useful is always great for maintaining the software.
