Long loading time when initializing Aws::Auth::AWSCredentials

[JeffreyChee]

Describe the bug

    TRACE("CAWSManager::InitFunctions 1\n");
    ASSERT(NULL == m_pcClientPtr);
    m_pcClientPtr = new std::shared_ptr<Aws::Lambda::LambdaClient>;
    if (NULL == m_pcClientPtr) {
        ASSERT(FALSE);
        return FALSE;
    }
    TRACE("CAWSManager::InitFunctions 2\n");
    Aws::Client::ClientConfiguration config;
    config.region = "us-east-1";
    config.disableIMDS = true;
    // this credential only have access lamba function and s3 read/write to a certain bucket
    Aws::Auth::AWSCredentials credentials("my accessKeyId", "my secretKey");
    TRACE("CAWSManager::InitFunctions 3\n");
    *m_pcClientPtr = Aws::MakeShared<Aws::Lambda::LambdaClient>(ALLOCATION_TAG, credentials, config);
    if (NULL == *m_pcClientPtr) {
        ASSERT(FALSE);
        return FALSE;
    }
    TRACE("CAWSManager::InitFunctions 4\n");

Expected Behavior

I Expected no or minimal delays between printing the log
CAWSManager::InitFunctions 1
CAWSManager::InitFunctions 2
CAWSManager::InitFunctions 3
CAWSManager::InitFunctions 4

but in between "CAWSManager::InitFunctions 2" and "CAWSManager::InitFunctions 3"
it takes around 5 seconds to finish constructing the Aws::Auth::AWSCredentials

may I know how should I eliminate this problem?
I saw a similar problem in the past where adding disableIMDS = true solves it, but this time it doesn't

Reproduction Steps

I can't seem to reproduce the same loading time that you're seeing. I modified your sample slightly to get it to run by itself, but I'm only seeing 1 millisecond elapse:

Can you provide more details on reproducing this. (a docker container would be great). It it possible something else in your test is causing this to take 5 seconds? Something in your environment?

Hi, im really new to the aws cpp sdk. I just download it from homebrew, put the lib and headers in my project and run it.
I did not configure any aws client on my computer at all.

[jmklix]

Can you try building this sdk from source and see if you can document your reproduction steps. Here are the steps for how to do this. Please let me know if you have any problems/questions while trying to do this.

[JeffreyChee]

I've tried to compile the sdk myself. but I keep getting runtime missing dylib errors. the homebrew version only needs a few dylibs, but when I build the sdk myself. it seem to ask for a lot of other dylibs.
I'll stick to using the homebrew version for my Mac build (for testing only) and using the mobile sdks for android and iOS.
Was thinking it should be best to use the cpp library for all platforms...

[JeffreyChee]

if only someone could provide a cpp binary package that works on all platform with instructions on which libraries are meant for which.

I sorry that you were unable to build this sdk without running into missing dylibs. We provide many different configuration options when building this sdk and there are many difference platforms that this sdk can be build for. So for those reasons and many others we don't provide a binary package. If you share the errors that you are currently running into I can try to help you build this sdk.
