## README

## AWS C S3

C99 library implementation for communicating with the S3 service, designed for maximizing throughput on high bandwidth EC2 instances.

## License

This library is licensed under the Apache 2.0 License.

## Usage

### Building

CMake 3.1+ is required to build.

`<install-path>` must be an absolute path in the following instructions.

#### Linux-Only Dependencies

If you are building on Linux, you will need to build aws-lc and s2n-tls first.

```
git clone git@github.com:awslabs/aws-lc.git
cmake -S aws-lc -B aws-lc/build -DCMAKE_INSTALL_PREFIX=<install-path>
cmake --build aws-lc/build --target install

git clone git@github.com:aws/s2n-tls.git
cmake -S s2n-tls -B s2n-tls/build -DCMAKE_INSTALL_PREFIX=<install-path> -DCMAKE_PREFIX_PATH=<install-path>
cmake --build s2n-tls/build --target install
```

#### Building aws-c-s3 and Remaining Dependencies

```
git clone git@github.com:awslabs/aws-c-common.git
cmake -S aws-c-common -B aws-c-common/build -DCMAKE_INSTALL_PREFIX=<install-path>
cmake --build aws-c-common/build --target install

git clone git@github.com:awslabs/aws-checksums.git
cmake -S aws-checksums -B aws-checksums/build -DCMAKE_INSTALL_PREFIX=<install-path> -DCMAKE_PREFIX_PATH=<install-path>
cmake --build aws-checksums/build --target install

git clone git@github.com:awslabs/aws-c-cal.git
cmake -S aws-c-cal -B aws-c-cal/build -DCMAKE_INSTALL_PREFIX=<install-path> -DCMAKE_PREFIX_PATH=<install-path>
cmake --build aws-c-cal/build --target install

git clone git@github.com:awslabs/aws-c-io.git
cmake -S aws-c-io -B aws-c-io/build -DCMAKE_INSTALL_PREFIX=<install-path> -DCMAKE_PREFIX_PATH=<install-path>
cmake --build aws-c-io/build --target install

git clone git@github.com:awslabs/aws-c-compression.git
cmake -S aws-c-compression -B aws-c-compression/build -DCMAKE_INSTALL_PREFIX=<install-path> -DCMAKE_PREFIX_PATH=<install-path>
cmake --build aws-c-compression/build --target install

git clone git@github.com:awslabs/aws-c-http.git
cmake -S aws-c-http -B aws-c-http/build -DCMAKE_INSTALL_PREFIX=<install-path> -DCMAKE_PREFIX_PATH=<install-path>
cmake --build aws-c-http/build --target install

git clone git@github.com:awslabs/aws-c-sdkutils.git
cmake -S aws-c-sdkutils -B aws-c-sdkutils/build -DCMAKE_INSTALL_PREFIX=<install-path> -DCMAKE_PREFIX_PATH=<install-path>
cmake --build aws-c-sdkutils/build --target install

git clone git@github.com:awslabs/aws-c-auth.git
cmake -S aws-c-auth -B aws-c-auth/build -DCMAKE_INSTALL_PREFIX=<install-path> -DCMAKE_PREFIX_PATH=<install-path>
cmake --build aws-c-auth/build --target install

git clone git@github.com:awslabs/aws-c-s3.git
cmake -S aws-c-s3 -B aws-c-s3/build -DCMAKE_INSTALL_PREFIX=<install-path> -DCMAKE_PREFIX_PATH=<install-path>
cmake --build aws-c-s3/build --target install
```

#### Running S3 sample

After installing all the dependencies, and building aws-c-s3, you can run the sample directly from the s3 build directory.

To download:
```
aws-c-s3/build/samples/s3/s3 cp s3://<bucket-name>/<object-name> <download-path> --region <region>
```
To upload:
```
aws-c-s3/build/samples/s3/s3 cp <upload-path> s3://<bucket-name>/<object-name> --region <region>
```
To list objects:
```
aws-c-s3/build/samples/s3/s3 ls s3://<bucket-name> --region <region>
```

## Testing

The unit tests require an AWS account with S3 buckets set up in a particular way.
Use the [test_helper script](./tests/test_helper/) to set this up.
