Fixes #12324

Motivation

Currently if any error happened during OAuth 2.0 authentication in C++ client, a runtime error would be thrown and could only be caught when creating an AuthOauth object, but could not be caught in Client's method like createProducer. It's not graceful. What's worse, there's no way for Python client that is a wrapper of C++ client to caught this exception.

Modifications

When ClientCredentialFlow::authenticate returns an invalid Oauth2TokenResult, catch the runtime_error thrown in Oauth2CachedToken's constructor and returns ResultAuthenticationError as AuthOauth2::getAuthData's returned value. Since getAuthData always returns ResultOk before this PR, the related docs are also modified.

Then when a CONNECT or AUTH_RESPONSE command is created, expose the result of getAuthData. If it's not ResultOk, close the connection and complete the connection's future with the result. After that, the Client's API will be completed with the result.

In addition, this PR also makes the error code of libcurl human readable by configuring CURLOPT_ERRORBUFFER.

Verifying this change

  • Make sure that the change passes the CI checks.

This change added tests AuthPluginTest.testOauth2Failure to verify when OAuth 2.0 authentication failed, the createProducer would return ResultAuthenticationError without any exception thrown.

[C++] Handle OAuth 2.0 exceptional cases gracefully (apache#12335)

Fixes apache#12324

Currently if any error happened during OAuth 2.0 authentication in C++ client, a runtime error would be thrown and could only be caught when creating an `AuthOauth` object, but could not be caught in `Client`'s method like `createProducer`. It's not graceful. What's worse, there's no way for Python client that is a wrapper of C++ client to caught this exception.

When `ClientCredentialFlow::authenticate` returns an invalid `Oauth2TokenResult`, catch the `runtime_error` thrown in `Oauth2CachedToken`'s constructor and returns `ResultAuthenticationError` as `AuthOauth2::getAuthData`'s returned value. Since `getAuthData` always returns `ResultOk` before this PR, the related docs are also modified.

Then when a CONNECT or AUTH_RESPONSE command is created, expose the result of `getAuthData`. If it's not `ResultOk`, close the connection and complete the connection's future with the result. After that, the `Client`'s API will be completed with the result.

In addition, this PR also makes the error code of libcurl human readable by configuring `CURLOPT_ERRORBUFFER`.

- [x] Make sure that the change passes the CI checks.

This change added tests `AuthPluginTest.testOauth2Failure` to verify when OAuth 2.0 authentication failed, the `createProducer` would return `ResultAuthenticationError` without any exception thrown.
