Utility for creating release candidates and promoting release candidates to a final relase.
Usage: release.py [subcommand]
release.py stage
  Builds and stages an RC for a release.
  The utility is interactive; you will be prompted for basic release information and guided through the process.
  This utility assumes you already have local a kafka git folder and that you
  have added remotes corresponding to both:
  (i) the github apache kafka mirror and
  (ii) the apache kafka git repo.
release.py stage-docs [kafka-site-path]
  Builds the documentation and stages it into an instance of the Kafka website repository.
  This is meant to automate the integration between the main Kafka website repository (https://github.com/apache/kafka-site)
  and the versioned documentation maintained in the main Kafka repository. This is useful both for local testing and
  development of docs (follow the instructions here: https://cwiki.apache.org/confluence/display/KAFKA/Setup+Kafka+Website+on+Local+Apache+Server)
  as well as for committers to deploy docs (run this script, then validate, commit, and push to kafka-site).
  With no arguments this script assumes you have the Kafka repository and kafka-site repository checked out side-by-side, but
  you can specify a full path to the kafka-site repository if this is not the case.
release.py release-email
  Generates the email content/template for sending release announcement email.

Subject: [ANNOUNCE] Apache Kafka %(release_version)s
The Apache Kafka community is pleased to announce the release for Apache Kafka %(release_version)s
<DETAILS OF THE CHANGES>
All of the changes in this release can be found in the release notes:
https://www.apache.org/dist/kafka/%(release_version)s/RELEASE_NOTES.html
You can download the source and binary release (Scala <VERSIONS>) from:
https://kafka.apache.org/downloads#%(release_version)s
---------------------------------------------------------------------------------------------------
Apache Kafka is a distributed streaming platform with four core APIs:
** The Producer API allows an application to publish a stream of records to
one or more Kafka topics.
** The Consumer API allows an application to subscribe to one or more
topics and process the stream of records produced to them.
** The Streams API allows an application to act as a stream processor,
consuming an input stream from one or more topics and producing an
output stream to one or more output topics, effectively transforming the
input streams to output streams.
** The Connector API allows building and running reusable producers or
consumers that connect Kafka topics to existing applications or data
systems. For example, a connector to a relational database might
capture every change to a table.
With these APIs, Kafka can be used for two broad classes of application:
** Building real-time streaming data pipelines that reliably get data
between systems or applications.
** Building real-time streaming applications that transform or react
to the streams of data.
Apache Kafka is in use at large and small companies worldwide, including
Capital One, Goldman Sachs, ING, LinkedIn, Netflix, Pinterest, Rabobank,
Target, The New York Times, Uber, Yelp, and Zalando, among others.

if not user_ok("""Requirements:
1. Updated docs to reference the new release version where appropriate.
2. JDK8 and JDK17 compilers and libraries
3. Your Apache ID, already configured with SSH keys on id.apache.org and SSH keys available in this shell session
4. All issues in the target release resolved with valid resolutions (if not, this script will report the problematic JIRAs)
5. A GPG key used for signing the release. This key should have been added to public Apache servers and the KEYS file on the Kafka site
6. Standard toolset installed -- git, gpg, gradle, sftp, etc.
7. ~/.gradle/gradle.properties configured with the signing properties described in the release process wiki, i.e.
      mavenUrl=https://repository.apache.org/service/local/staging/deploy/maven2
      mavenUsername=your-apache-id
      mavenPassword=your-apache-passwd
      signing.keyId=your-gpgkeyId
      signing.password=your-gpg-passphrase
      signing.secretKeyRingFile=/Users/your-id/.gnupg/secring.gpg (if you are using GPG 2.1 and beyond, then this file will no longer exist anymore, and you have to manually create it from the new private key directory with "gpg --export-secret-keys -o ~/.gnupg/secring.gpg")
8. ~/.m2/settings.xml configured for pgp signing and uploading to apache release maven, i.e.,
       <server>
          <id>apache.releases.https</id>
          <username>your-apache-id</username>
          <password>your-apache-passwd</password>
        </server>
        <server>
            <id>your-gpgkeyId</id>
            <passphrase>your-gpg-passphrase</passphrase>
        </server>
        <profile>
            <id>gpg-signing</id>
            <properties>
                <gpg.keyname>your-gpgkeyId</gpg.keyname>
                <gpg.passphraseServerId>your-gpgkeyId</gpg.passphraseServerId>
            </properties>
        </profile>
9. You may also need to update some gnupgp configs:
        ~/.gnupg/gpg-agent.conf
        allow-loopback-pinentry
        ~/.gnupg/gpg.conf
        use-agent
        pinentry-mode loopback
        echo RELOADAGENT | gpg-connect-agent

Ok. We've built and staged everything for the %(rc_tag)s.
Now you should sanity check it before proceeding. All subsequent steps start making RC data public.
Some suggested steps:
 * Grab the source archive and make sure it compiles: https://home.apache.org/~%(apache_id)s/kafka-%(rc_tag)s/kafka-%(release_version)s-src.tgz
 * Grab one of the binary distros and run the quickstarts against them: https://home.apache.org/~%(apache_id)s/kafka-%(rc_tag)s/kafka_2.13-%(release_version)s.tgz
 * Extract and verify one of the site docs jars: https://home.apache.org/~%(apache_id)s/kafka-%(rc_tag)s/kafka_2.13-%(release_version)s-site-docs.tgz
 * Build a sample against jars in the staging repo: (TODO: Can we get a temporary URL before "closing" the staged artifacts?)
 * Validate GPG signatures on at least one file:
      wget https://home.apache.org/~%(apache_id)s/kafka-%(rc_tag)s/kafka-%(release_version)s-src.tgz &&
      wget https://home.apache.org/~%(apache_id)s/kafka-%(rc_tag)s/kafka-%(release_version)s-src.tgz.asc &&
      wget https://home.apache.org/~%(apache_id)s/kafka-%(rc_tag)s/kafka-%(release_version)s-src.tgz.md5 &&
      wget https://home.apache.org/~%(apache_id)s/kafka-%(rc_tag)s/kafka-%(release_version)s-src.tgz.sha1 &&
      wget https://home.apache.org/~%(apache_id)s/kafka-%(rc_tag)s/kafka-%(release_version)s-src.tgz.sha512 &&
      gpg --verify kafka-%(release_version)s-src.tgz.asc kafka-%(release_version)s-src.tgz &&
      gpg --print-md md5 kafka-%(release_version)s-src.tgz | diff - kafka-%(release_version)s-src.tgz.md5 &&
      gpg --print-md sha1 kafka-%(release_version)s-src.tgz | diff - kafka-%(release_version)s-src.tgz.sha1 &&
      gpg --print-md sha512 kafka-%(release_version)s-src.tgz | diff - kafka-%(release_version)s-src.tgz.sha512 &&
      rm kafka-%(release_version)s-src.tgz* &&
      echo "OK" || echo "Failed"
 * Validate the javadocs look ok. They are at https://home.apache.org/~%(apache_id)s/kafka-%(rc_tag)s/javadoc/
