# Arrow Developer Scripts

This directory contains scripts useful to developers when packaging,
testing, or committing to Arrow.

## Verifying Release Candidates

We have provided a script to assist with verifying release candidates:

```shell
bash dev/release/verify-release-candidate.sh 0.7.0 0
```

Currently this only works on Linux (patches to expand to macOS welcome!). Read
the script for information about system dependencies.

On Windows, we have a script that verifies C++ and Python (requires Visual
Studio 2015):

```
dev/release/verify-release-candidate.bat apache-arrow-0.7.0.tar.gz
```

### Verifying the JavaScript release

For JavaScript-specific releases, use a different verification script:

```shell
bash dev/release/js-verify-release-candidate.sh 0.7.0 0
```

# Integration testing

Build the following base image used by multiple tests:

```shell
docker build -t arrow_integration_xenial_base -f docker_common/Dockerfile.xenial.base .
```
