Making an OpenJPA Release

These instructions guide through the steps of making an official OpenJPA release.

These instructions are specific to the incubating status of OpenJPA. Once OpenJPA is elevated out of incubation, these instructions will need to be updated.

Prerequisites

  1. You should have read the Apache Guide To Release Management During Incubation
  2. You must have shell access to people.apache.org
  3. You must have the following utilities installed on your local machine and available in your path:

Tasks that need to be performed for each release

In the examples below, it is assumed that the current committed version of OpenJPA is 0.9.6-incubating-SNAPSHOT, and the version of the official release will be 0.9.6-incubating
1 Make sure the One time setup steps have been performed
2 If releasing from the trunk, first make a branch from which to make the release. Releasing from a branch will allow any cosmetic changes that need to be made for the release to be approved to be done without preventing other more distruptive advances in the trunk from potentially causing problems with the release. A branch can be made by running:
 
svn copy -m "OpenJPA Release 0.9.6-incubating"
  https://svn.apache.org/repos/asf/incubator/openjpa/trunk 
  https://svn.apache.org/repos/asf/incubator/openjpa/branches/0.9.6-incubating
3 Update the POMs to remove "-SNAPSHOT" from the version. If you have perl installed, you can easily do it with a single command:
 
perl -pi -e 's;<version>0.9.6-incubating-SNAPSHOT</version>;<version>0.9.6-incubating</version>;g' pom.xml */pom.xml
4 Commit the POM changes
 
svn commit -m "Updated to version 0.9.6-incubating"
5 Perform the build with documentation and install it in the local repository (this step is required because there is a bug in Maven's javadoc generation aggregated between multiple modules):
 
mvn clean install -Pdocbook-profile,sign-release
 
This operation will also sign the release files with the gpg utility using the <username>@apache.org key. If your code signing key is under a different address, specify it by appending the following argument to the command above: -Dopenjpa.release.keyAlias=mysigningalias@somedomain.org
6 Verify the signatures:
 
gpg --multifile --verify openjpa-project/target/assembly/*.asc
7 Now actually build the javadocs and perform the deploy upload:
 
mvn verify deploy -Pjavadoc-profile,sign-release
8 Tag the branch with the release number:
 
svn copy -m "OpenJPA Release 0.9.6-incubating"
  https://svn.apache.org/repos/asf/incubator/openjpa/branches/0.9.6-incubating 
  https://svn.apache.org/repos/asf/incubator/openjpa/tags/0.9.6-incubating
9 Update the pom.xml files to the subsequent version with the -SNAPSHOT suffix:
 
perl -pi -e "s;<version>0.9.6-incubating</version>;<version>0.9.7-incubating-SNAPSHOT</version>;g" pom.xml */pom.xml
10 Commit the POM changes
 
svn commit -m "Updated to version 0.9.7-incubating-SNAPSHOT"
11 Start a vote for the release on the open-jpa-dev@incubator.apache.org mailing list. For an example of the mail, see this archived vote
12 If the vote is successful after 3 days, mail general@incubator.apache.org starting a vote for authorization to release
13 Once that vote is successful, update the http://cwiki.apache.org/openjpa/downloads.html page with information about the download
14 The documentation links at http://cwiki.apache.org/openjpa/documentation.html also needs to be updated. You can do this by checking out a copy of the OpenJPA static site documents into a scratch directory, unpacking the OpenJPA binary into the docs section, adding the new docs, and then committing and updating the docs on the server-side:
 
mkdir /tmp/openjpa-docs/
cd /tmp/openjpa-docs/
jar xvf OPENJPA_DIR/openjpa-project-0.9.6-incubating-binary.zip

mkdir /tmp/openjpa-site/
cd /tmp/openjpa-site/
svn co https://svn.apache.org/repos/asf/incubator/openjpa/site/docs

cd docs/docs/
mv /tmp/openjpa-docs/openjpa-0.9.6-incubating/docs/ openjpa-0.9.6-incubating
rm latest
ln -s openjpa-0.9.6-incubating latest

svn add openjpa-0.9.6-incubating
svn commit -m "Added documentation for openjpa-0.9.6-incubating release" .

ssh people.apache.org
svn co http://svn.apache.org/repos/asf/incubator/openjpa/site/docs /www/incubator.apache.org/openjpa
  The static site will take a little while to synchronize, but eventually you should see the new documentation version at http://incubator.apache.org/openjpa/docs/. Once you see that, add a link to the new documentation release at http://cwiki.apache.org/openjpa/documentation.html

One time setup

These setup steps only need to be performed on a particular machine once.

Developers using Linux workstations can skip over the references to PuTTY and Cygwin

Create and install a SSH key

1 Install PuTTY
2 Use PuttyGen to create a SSH key (see Putty help for details)
3 Use PuTTY to ssh to people.apache.org
4 Create a ~/.ssh folder
5 pscp your SSH public key to ~/authorized_keys
6 ssh to p.a.o
7 Create a ~\.ssh folder and move authorized_keys there
8 Configure putty to use your private key and save the session

Create a PGP key

1 Install cgywin, including utils/gpg
2 Generate a key with $ gpg --gen-key
3 Backup your cygwin home directory to another media
4 Add your key to https://svn.apache.org/repos/asf/incubator/openjpa/site/docs/KEYS

Update Maven settings for our servers

1 Create a settings.xml under .m2 (in your Document and Settings folder in Windows)
 
settings.xml
<settings xmlns="http://maven.apache.org/POM/4.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <servers>
       <server>
          <id>people.apache.org</id>
          <username>$USERNAME</username>
          <privateKey>$PATH_TO_PRIVATE_KEY</privateKey>
          <directoryPermissions>775</directoryPermissions>
          <filePermissions>644</filePermissions>
       </server>
    </servers>
</settings>

Expose a copy of known hosts to Maven

1 From cygwin, ssh to people.apache.org, save the public key if prompted, and exit
  cygwin will save the known hosts to your ~/.ssh folder, but the script cannot access it there (from Windows)
2 From cygwin (not Windows) create another .ssh folder at
3 Copy the known_hosts file to the new .ssh folder

Example shell script to perform the steps above

mkopenjparelease.sh
#!/bin/sh -pve
# Author: Marc Prud'hommeaux <mprudhom@apache.org>
# Performs the release steps described at:
#
#   http://cwiki.apache.org/openjpa/releasing-openjpa.html
# 
# It will do the following:
#
# 1. Check out a fresh version of openjpa from the branch
# 2. Update the openjpa pom.xml files to have the new version
# 3. Commit the pom.xml changes
# 4. Make the release files
# 5. Verify the signature
# 6. Test the examples in the release
# 7. Perform the deploy
# 8. Tag the view using "svn copy"
