... Are there any known issues on CentOS? Have we missed something in using the SDK on Linux as opposed to macOS?

Thanks for the super quick reply. Even when scoped, though, the same <error reading variable: Cannot access memory at address 0xffffffffffffffe8> for s3_put_outcome persist.

sorry, I missed the first several lines. You can't use ANY sdk types or functions prior to the initAPI call. It swaps the memory manager out from under you. can you move aws::string etc... after the init call and see if that helps?

Moving the SDK types now yields a Python Exception(?):

Python for this machine is unmodified system default, version 2.7.5.

In an attempt to rule out any unknown conflicts as well as lay out a fast and easily reproducible test (and in hopes that another distribution would magically solve everything), we set out to build only AWS example code - https://github.com/awsdocs/aws-doc-sdk-examples/blob/master/cpp/example_code/s3/put_object.cpp - upon a fresh, new EC2 using ubuntu/images/hvm-ssd/ubuntu-xenial-16.04-amd64-server-20170414 (ami-80861296).

The results were still failures. Below is an annotated transcript - again, if we are missing any steps or if anything seems out of place please advise.

First, we got ourselves up-to-date, installed dependencies, and tested the awscli to rule out any networking issues:

sudo apt-get update
sudo apt-get install build-essential git cmake libcurl4-nss-dev libssl-dev zlib1g-dev pkgconf gdb awscli
AWS_ACCESS_KEY_ID='XXXXXXXXXXXXXXXXXXXX' AWS_SECRET_ACCESS_KEY='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX' aws s3 cp ../FILENAME.JPG s3://BUCKET_NAME/KEY_PATH/FILENAME.JPG

The output was upload: ../FILENAME.JPG to s3://BUCKET_NAME/KEY_PATH/FILENAME.JPG and the file was confirmed to have made it to our bucket. Success! Next we moved onto the SDK and example:

wget https://github.com/aws/aws-sdk-cpp/archive/1.0.112.tar.gz
tar zxvf 1.0.112.tar.gz
cd aws-sdk-cpp-1.0.112/
mkdir BUILD
cd BUILD/
cmake -DCMAKE_BUILD_TYPE=Debug -DBUILD_ONLY="core;s3" ..
make
sudo make install
cd ../..
wget https://raw.githubusercontent.com/awsdocs/aws-doc-sdk-examples/master/cpp/example_code/s3/put_object.cpp
g++ put_object.cpp -g --std=c++11 `pkg-config aws-cpp-sdk-s3 --cflags` -o put_object `pkg-config aws-cpp-sdk-s3 --libs`
AWS_ACCESS_KEY_ID='XXXXXXXXXXXXXXXXXXXX' AWS_SECRET_ACCESS_KEY='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX' ./put_object BUCKET_NAME KEY_PATH/FILENAME.JPG ../FILENAME.JPG

The output now, though, was sadly familiar:

Uploading ../FILENAME.JPG to S3 bucket BUCKET_NAME at key KEY_PATH/FILENAME.JPG
PutObject error:  Unable to connect to endpoint

And so, we fire up gdb:

AWS_ACCESS_KEY_ID='XXXXXXXXXXXXXXXXXXXX' AWS_SECRET_ACCESS_KEY='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX' gdb ./put_object

We note that the <error reading variable: Cannot create a lazy string with address 0x0, and a non-zero length.> bits look out of place, but have no clues as to their cause nor solution. Also worth noting is the same steps above on our development macOS machine still work as expected.

Any ideas?

Don't you have to set the region when constructing the s3_client?

Aws::Client::ClientConfiguration config; config.region = "us-west-1"; // for example Aws::S3::S3Client s3_client(config);

In an attempt to rule out any unknown conflicts as well as lay out a fast and easily reproducible test (and in hopes that another distribution would magically solve everything), we set out to build only AWS example code - https://github.com/awsdocs/aws-doc-sdk-examples/blob/ master/cpp/example_code/s3/put_object.cpp - upon a fresh, new EC2 using ubuntu/images/hvm-ssd/ubuntu-xenial-16.04-amd64-server-20170414 (ami-80861296).

The results were still failures. Below is an annotated transcript - again, if we are missing any steps or if anything seems out of place please advise.

First, we got ourselves up-to-date, installed dependencies, and tested the awscli to rule out any networking issues:

sudo apt-get update sudo apt-get install build-essential git cmake libcurl4-nss-dev libssl-dev zlib1g-dev pkgconf gdb awscli AWS_ACCESS_KEY_ID='XXXXXXXXXXXXXXXXXXXX' AWS_SECRET_ACCESS_KEY='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX' aws s3 cp ../FILENAME.JPG s3://BUCKET_NAME/KEY_PATH/FILENAME.JPG

The output was upload: ../FILENAME.JPG to s3://BUCKET_NAME/KEY_PATH/ FILENAME.JPG and the file was confirmed to have made it to our bucket. Success! Next we moved onto the SDK and example:

wget https://github.com/aws/aws-sdk-cpp/archive/1.0.112.tar.gz tar zxvf 1.0.112.tar.gzcd aws-sdk-cpp-1.0.112/ mkdir BUILDcd BUILD/ cmake -DCMAKE_BUILD_TYPE=Debug -DBUILD_ONLY="core;s3" .. make sudo make installcd ../.. wget https://raw.githubusercontent.com/awsdocs/aws-doc-sdk-examples/master/cpp/example_code/s3/put_object.cpp g++ put_object.cpp -g --std=c++11 pkg-config aws-cpp-sdk-s3 --cflags -o put_object pkg-config aws-cpp-sdk-s3 --libs AWS_ACCESS_KEY_ID='XXXXXXXXXXXXXXXXXXXX' AWS_SECRET_ACCESS_KEY='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX' ./put_object BUCKET_NAME KEY_PATH/FILENAME.JPG ../FILENAME.JPG

The output now, though, was sadly familiar:

Uploading ../FILENAME.JPG to S3 bucket BUCKET_NAME at key KEY_PATH/FILENAME.JPG PutObject error: Unable to connect to endpoint

And so, we fire up gdb:

We note that the <error reading variable: Cannot create a lazy string with address 0x0, and a non-zero length.> bits look out of place, but have no clues as to their cause nor solution. Also worth noting is the same steps above on our development macOS machine still work as expected.

Any ideas?

Don't you have to set the region when constructing the s3_client?

Aws::Client::ClientConfiguration config; config.region = "us-west-1"; // for example Aws::S3::S3Client s3_client(config);

In an attempt to rule out any unknown conflicts as well as lay out a fast and easily reproducible test (and in hopes that another distribution would magically solve everything), we set out to build only AWS example code - https://github.com/awsdocs/aws-doc-sdk-examples/blob/master/ cpp/example_code/s3/put_object.cpp - upon a fresh, new EC2 using ubuntu/images/hvm-ssd/ubuntu-xenial-16.04-amd64-server-20170414 (ami-80861296).

The results were still failures. Below is an annotated transcript - again, if we are missing any steps or if anything seems out of place please advise.

First, we got ourselves up-to-date, installed dependencies, and tested the awscli to rule out any networking issues:

sudo apt-get update sudo apt-get install build-essential git cmake libcurl4-nss-dev libssl-dev zlib1g-dev pkgconf gdb awscli AWS_ACCESS_KEY_ID='XXXXXXXXXXXXXXXXXXXX' AWS_SECRET_ACCESS_KEY='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX' aws s3 cp ../FILENAME.JPG s3://BUCKET_NAME/KEY_PATH/FILENAME.JPG

The output was upload: ../FILENAME.JPG to s3://BUCKET_NAME/KEY_PATH/FILE NAME.JPG and the file was confirmed to have made it to our bucket. Success! Next we moved onto the SDK and example:

wget https://github.com/aws/aws-sdk-cpp/archive/1.0.112.tar.gz tar zxvf 1.0.112.tar.gzcd aws-sdk-cpp-1.0.112/ mkdir BUILDcd BUILD/ cmake -DCMAKE_BUILD_TYPE=Debug -DBUILD_ONLY="core;s3" .. make sudo make installcd ../.. wget https://raw.githubusercontent.com/awsdocs/aws-doc-sdk-examples/master/cpp/example_code/s3/put_object.cpp g++ put_object.cpp -g --std=c++11 pkg-config aws-cpp-sdk-s3 --cflags -o put_object pkg-config aws-cpp-sdk-s3 --libs AWS_ACCESS_KEY_ID='XXXXXXXXXXXXXXXXXXXX' AWS_SECRET_ACCESS_KEY='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX' ./put_object BUCKET_NAME KEY_PATH/FILENAME.JPG ../FILENAME.JPG

The output now, though, was sadly familiar:

Uploading ../FILENAME.JPG to S3 bucket BUCKET_NAME at key KEY_PATH/FILENAME.JPG PutObject error: Unable to connect to endpoint

And so, we fire up gdb:

We note that the <error reading variable: Cannot create a lazy string with address 0x0, and a non-zero length.> bits look out of place, but have no clues as to their cause nor solution. Also worth noting is the same steps above on our development macOS machine still work as expected.

Any ideas?

Your response is appreciated, @yasushi-saito, but the bucket in testing is in the default region "us-east-1". Both the simple AWS example code and my full application function on my development machine whether such is specified or not. On any EC2 nothing works, regions or no regions.

And, my development environment does not have default credentials set. I do receive authentication errors when running anything without the ENV variables, but when run as shown "it just works".

We've tried more distributions, building the complete SDK, and exhausted more avenues such as trying other VPCs and other AWS accounts. Still the same, nothing but failure. On every EC2 the aws-cpp-sdk-s3-integration-tests yields 0 passing (but of course it's fine on my local development machine).

What could we be overlooking? Why can we get tests to pass everywhere except Amazon's own servers?

can you upload a trace level log?

Gladly, but I'm not familiar with gtests nor the SDK logging. Any pointers as to where/how logging could be added to either the integration tests or the example code would be greatly appreciated.

Check SDKOptions for your InitAPI() call. Just set the logging level to Trace and that will do the trick.

I will say this. We run these tests from public Ec2 instances, so there is nothing inherently preventing this from running on Ec2.

@JonathanHenson We, of course, assumed this was heavily tested upon EC2. Our experience so far, though, is zero for three when it comes to Linux distributions on EC2, from more than one VPC and AWS account.

Any info you could share on these tests? Which distributions? Exactly how was the SDK built and installed?

Attached is a Trace-level log from CentOS 7. We noted Curl returned error code 51: aws-sdk-cpp-centos-trace.txt Will track down output from other distributions known to have failed us.

Ok, so can you turn ssl verification off in your ClientConfiguration, and rerun your code, just to verify that's what's wrong.

If that succeeds you have a few options. Either a.) update the certs on the box that curl is using (in the location curl looks for them for your distribution), or b.) put the certs on the box anywhere and pass the ca_path or ca_file options to the clientConfiguration.

I would upload the Trace log from the same test on ubuntu/images/hvm-ssd/ubuntu-xenial-16.04-amd64-server-20170414 (ami-80861296) but it is nearly verbatim. The difference is Ubuntu went with Curl returned error code 77.

What is the process for updating these certificates? Happen to have a link to details?

And will being up-to-date on said certificates be a requirement? That would be a deal-breaking kinda of thing for a production application.

out of curiosity, what happens if you turn virtual style addressing off?

It's a constructor argument for S3Client.

ah!

Your bucket name has an underscore in it. I suspect it isn't working because with virtual style addressing the bucket name is part of the dns lookup. _ is not universally allowed for dns. Hopefully moving to path style addressing should fix the issue.

We only see, credentials, config, and signPayloads constructor args in the docs: http://sdk.amazonaws.com/cpp/api/LATEST/class_aws_1_1_s3_1_1_s3_client.html

Are you referring to something in the ClientConfiguration? Not sure which, if so.

Sorry, looks like my docs pipeline hasn't deployed with the latest change. I literally made this change on last Wednesday to use virtual bucket addressing.

https://github.com/aws/aws-sdk-cpp/blob/master/aws-cpp-sdk-s3/include/aws/s3/S3Client.h#L409

Looks like that worked!

Worth noting: regardless of bucket name characters (we've tested periods, underscores, or none at all), we did not have any success until useVirtualAdressing was set to false. This was the case on both CentOS and Ubuntu.

Let us know if any info on our testing environments would be useful for you.

We've added DNS validation checks when useVirtualAddressing is set to true. If the DNS validation fails, S3Client will fallback to the URL based addressing instead.
