ListObjectsV2Request timeout on Linux

[jmsundar]

Using SDK v1.3.1 on Ubuntu 14.04 with curl version 7.57.0, compiled with gcc 4.9.4 with default cmake options.

We are unable to list objects from an s3 bucket. The code is below and TRACE level log is here:
aws_sdk_2017-12-11-13.log
The same code works perfectly on macOS 10.13, compiled with Apple LLVM version 9.0.0 (clang-900.0.39.2).

Vector<S3::Model::Object> S3Manager::list_objects()
{
    std::cout << "Objects in S3 bucket: " << m_bucket << std::endl;
    S3::Model::ListObjectsV2Request objects_request;
    objects_request.WithBucket(m_bucket);

    auto list_objects_outcome = s3_client->ListObjectsV2(objects_request);

    if (list_objects_outcome.IsSuccess())
    {
        return list_objects_outcome.GetResult().GetContents();
    }
    else
    {
        ios_log(ERROR, "listObjects error: %s %s\n", list_objects_outcome.GetError().GetExceptionName().c_str(), list_objects_outcome.GetError().GetMessage().c_str());
        return Vector<S3::Model::Object>();
    }
}

This function was originally called from the _init function of a shared library. On Linux, moving the function call out of _init was successful. Leaving it in the _init function, and setting config.endpointOverride to the ipaddress returned by nslookup works as well. So this seems to be some interaction between the dns lookup and _init function.

Did you use rate limiter to hit the above issue?

I hit a similar issue which is described in #806

Nah, our issue was entirely related to dns not working in _init for our library. Rate limiter was not set. Closing because I meant to close it in December.
