# Package assembly

This set of scripts collect CI artifacts from a local directory or S3, and
assembles them into a package structure defined by a packaging class in a
staging directory.
For the NugetPackage class the NuGet tool is then run (from within docker) on
this staging directory to create a proper NuGet package (with all the metadata).
While the StaticPackage class creates a tarball.

The finalized nuget package maybe uploaded manually to NuGet.org

## Requirements

 * Requires Python 3
 * Requires Docker
 * (if --s3) Requires private S3 access keys for the librdkafka-ci-packages bucket.



## Usage

1. Trigger CI builds by creating and pushing a new release (candidate) tag
   in the librdkafka repo. Make sure the tag is created on the correct branch.

    $ git tag v0.11.0-RC3
    $ git push origin v0.11.0-RC3

2. Wait for CI builds to finish, monitor the builds here:

 * https://travis-ci.org/edenhill/librdkafka
 * https://ci.appveyor.com/project/edenhill/librdkafka

Or if using SemaphoreCI, just have the packaging job depend on prior build jobs
in the same pipeline.

3. On a Linux host, run the release.py script to assemble the NuGet package

    $ cd packaging/nuget
    # Specify the tag
    $ ./release.py v0.11.0-RC3
    # Optionally, if the tag was moved and an exact sha is also required:
    # $ ./release.py --sha <the-full-git-sha> v0.11.0-RC3

4. If all artifacts were available the NuGet package will be built
   and reside in the current directory as librdkafka.redist.<v-less-tag>.nupkg

5. Test the package manually

6. Upload the package to NuGet

 * https://www.nuget.org/packages/manage/upload

7. If you trust this process you can have release.py upload the package
   automatically to NuGet after building it:

    $ ./release.py --retries 100 --upload your-nuget-api.key v0.11.0-RC3



## Other uses

### Create static library bundles

To create a bundle (tarball) of librdkafka self-contained static library
builds, use the following command:

    $ ./release.py --class StaticPackage v1.1.0


### Clean up S3 bucket

To clean up old non-release/non-RC builds from the S3 bucket, first check with:

    $ AWS_PROFILE=.. ./cleanup-s3.py --age 360

Verify that the listed objects should really be deleted, then delete:

    $ AWS_PROFILE=.. ./cleanup-s3.py --age 360 --delete
