Making an OpenJPA 1.0.x or 1.1.x Release

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

Prerequisites

You should read the OpenJPA Release Policy to decide on the name of the new release, based on the content.
You should read the Apache Release FAQ
You must have shell access to people.apache.org
You must have the following utilities installed on your local machine and available in your path:
- JDK 1.4 / 1.5
- ssh
- Maven 2
- gnupg
For Windows users, install Cygwin in addition to the above utilities
- Make sure the Net/openssh and Utils/gnupg packages are installed that come with Cygwin installation.
- Optional: Putty

Tasks that need to be performed for each release

In the examples below, it is assumed that the release name will be 1.0.1, and that the current checked-in version name is 1.0.1-SNAPSHOT and stored in the branch named 1.0.x.

Monday, 12:00 Make sure the One time setup steps have been performed

Monday, 12:01

Create a sub-branch off of the parent 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 disruptive advances in the trunk from potentially causing problems with the release. A branch can be made by running:

svn copy -m "OpenJPA Release 1.0.1 branch" \
  https://svn.apache.org/repos/asf/openjpa/branches/1.0.x \
  https://svn.apache.org/repos/asf/openjpa/branches/1.0.1

Monday, 12:02

Check out a clean branch from which to build the release:

svn checkout https://svn.apache.org/repos/asf/openjpa/branches/1.0.1
cd 1.0.1

Make sure there is no space characters in the path to the build root subdirectory, i.e. "c:\OpenJPA 1.0.1 Release\build". See "Space Character in Build Root Path"

Monday, 12:03

Update all the POMs to remove "-SNAPSHOT" suffix from the version. If you have perl installed, you can easily do it with a single command:

perl -pi -e "s;<version>1.0.1-SNAPSHOT</version>;<version>1.0.1</version>;g" \
    pom.xml */pom.xml */*/pom.xml

Update the <scm.dir> property in the top level pom.xml to the 1.0.1 release. \
Update the <developer> element in the top level pom.xml if new committers are added or removed. This applies to the 1.0.x branch only.

Monday, 12:10 Verify that LICENSE.txt contains up to date licenses for any dependencies which are included in our distribution.
Any jars or source code which is included with the OpenJPA distribution that is not covered by the Apache license must be noted in LICENSE.txt. Two examples of this are the persistence and orm dtds (licensed under the CDDL) and Serp. If any new non Apache dependencies have been introduced they will have to be covered here as well. If any discrepancies are found update LICENSE.txt and commit the changes.

Monday, 12:15

Update BUILDING.txt, CHANGES.txt and RELEASE-NOTES.html

BUILDING.txt should be included in the source tarball and contains instructions on how to build OpenJPA. Prior to shipping a release we should ensure that those instructions are accurate.
CHANGES.txt contains a text representation of all the changes which have been made since the preceding release. Most of the contents of this file can be generated through JIRA's release notes mechanism here
RELEASE-NOTES.html contains general information on the OpenJPA project as well as an html version of the changes since the preceding version. The html change log may also be generated via JIRA.

Monday, 12:20

Commit the POM changes

svn commit -m "Updated to version 1.0.1 for the release"

Monday, 12:21

Perform an initial build and install it in the local repository (this step is only required because of an open bug with Maven's javadoc plugin):

mvn clean install -Dtest=false

Monday, 12:23

Now build the release locally, which will build and test, run the Apache Release Audit Tool to verify license headers, generate the javadoc and docbook PDF and HTML, run through the JPA TCK, build the source and binariy assemblies in target/site/downloads/, and sign the release files.

export MAVEN_OPTS=-Xmx1000m
mvn --batch-mode deploy site \
    -Ptck-profile,examples-profile,license-verify-profile,javadoc-profile,docbook-profile,sign-release \
    -Djava14.jar=${JAVA_HOME}/../../1.4/Classes/classes.jar \
    -Dtck.zip=${HOME}/.m2/privaterepos/jpa-1_0b-tck.zip

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: -[email protected]

The java14.jar path should be changed to the local install path for the JDK 1.4 rt.jar so that JDK 1.4 verification can take place.

The tck.zip path should be changed to the local install path to the JPA TCK so that the TCK can be run against the release. If you are not licensed to access the TCK, remove the tck-profile profile and -Dtck.zip property from the command. Ask someone who has access to run the TCK for you.

The examples-profile has problem running automatically in this maven build task. You will need to run the examples manually. Run the maven command without the examples-profile, then perform the following steps to run the example:

mkdir openjpa-integration\examples\target\examples
unzip target\site\downloads\apache-openjpa-1.0.1-binary.zip -d openjpa-integration\examples\target\examples
cd openjpa-integration\examples\target\examples\apache-openjpa-1.0.1\examples\hellojpa
ant
cd ..\relations
ant
cd ..\reversemapping
ant

Monday, 13:00

Verify the signatures:

gpg --multifile --verify target/site/downloads/*.asc

Monday, 13:01

Upload the release candidate to http://openjpa.apache.org/builds/1.0.1/downloads/:

mvn site:deploy

Bear in mind that uploads to people.apache.org/www/openjpa.apache.org/builds/ are not visible at http://openjpa.apache.org/builds until after the hourly synchronization has taken place, as described at http://www.apache.org/dev/project-site.html.

Monday, 15:00 Start a vote for the release on the [email protected] mailing list. Votes made by committers and members of the OpenJPA project are considered binding for this vote. For an example of the mail, see this archived 1.0.0 vote

Tuesday, Wednesday While waiting for the vote to complete, perform whatever manual review and testing on the release you deem appropriate.

Thursday, 15:00 If the vote is successful after 3 days tally the votes in an email to [email protected], like this one.

Thursday, 15:10

Make the OpenJPA assemblies available to the Apache mirroring system by copying them over on people.apache.org:

ssh people.apache.org
cp -r /www/openjpa.apache.org/builds/1.0.1/downloads/* /www/www.apache.org/dist/openjpa/1.0.1
chgrp -R openjpa /www/www.apache.org/dist/openjpa/1.0.1
chmod -R g+w /www/www.apache.org/dist/openjpa/1.0.1

The OpenJPA binary release will be available via the link http://www.apache.org/dyn/closer.cgi/openjpa/1.0.1/apache-openjpa-1.0.1-binary.zip after 24 hours, as per the Apache mirroring information.

Thursday, 15:15

Now that the release is locked down, convert the writeable 1.0.1 branch to a (du jure) read-only tag:

svn mv -m "OpenJPA Release 1.0.1 tag" \
  https://svn.apache.org/repos/asf/openjpa/branches/1.0.1 \
  https://svn.apache.org/repos/asf/openjpa/tags/1.0.1

Thursday, 15:16

Check out the parent branch and bump up the release number to be the next snapshot version:

svn checkout https://svn.apache.org/repos/asf/openjpa/branches/1.0.x
cd 1.0.x
perl -pi -e "s;<version>1.0.1-SNAPSHOT</version>;<version>1.0.2-SNAPSHOT</version>;g" \
    pom.xml */pom.xml */*/pom.xml
svn commit -m "Updating version in branch to 1.0.2-SNAPSHOT"

Thursday, 15:20

Update the http://cwiki.apache.org/openjpa/downloads.html page with links to the download mirrors, using the existing entries as templates.

All artifacts (apache-openjpa-1.0.1-binary.zip and apache-openjpa-1.0.1-source.zip) must link to the mirrors, but signatures (apache-openjpa-1.0.1-binary.zip.asc and apache-openjpa-1.0.1-source.zip.asc) must not link to mirrors.

Thursday, 15:30

The documentation on the server-side must manually be extracted on people.apache.org, and the links at http://openjpa.apache.org/documentation.html need to be updated with the new versions and the "latest" documentation symbolic links need to be updated:

cd /www/openjpa.apache.org/builds/1.0.1/
unzip downloads/apache-openjpa-1.0.1-binary.zip
rm /www/openjpa.apache.org/docs/latest
ln -fvs ../builds/1.0.1/apache-openjpa-1.0.1/docs/ /www/openjpa.apache.org/docs/latest

Then point the links on http://openjpa.apache.org/documentation.html to:

HTML Manual: http://openjpa.apache.org/builds/1.0.1/apache-openjpa-1.0.1/docs/manual/index.html
HTML Manual (single-page): http://openjpa.apache.org/builds/1.0.1/apache-openjpa-1.0.1/docs/manual/manual.html
PDF Manual: http://openjpa.apache.org/builds/1.0.1/apache-openjpa-1.0.1/docs/manual/manual.pdf
Javadocs: http://openjpa.apache.org/builds/1.0.1/apache-openjpa-1.0.1/docs/javadoc/index.html

Thursday, 15:45

Merge the staged maven2 repository jars to with the official repository to rsync. This is currently a difficult process that requires the maven-staging-plugin, which much be built from source. The process looks something like this (executed in the root of your local OpenJPA checkout):

svn co http://svn.apache.org/repos/asf/maven/plugins/trunk/maven-stage-plugin/ \
    /tmp/maven-stage-plugin
mvn -f /tmp/maven-stage-plugin/pom.xml clean install
for i in $(find openjpa-* -name m2-repository | egrep -v "openjpa-project|openjpa-integration|openjpa-examples"); do
    cd $i
    mvn stage:copy -Dsource=file://. \
    -Dtarget=scp://people.apache.org:/www/people.apache.org/repo/m2-ibiblio-rsync-repository \
    -Dversion=1.0.1
    cd -
done

This process requires Maven 2.0.5. It is currently quite delicate and error-prone. Once the maven-stage-plugin is released, it should be possible to make it more automated.

Window/Cygwin user: See Merging local repository to remote repository in Cygwin/Windows

Linux users: You may need to change the '-Dsource=' option to read '-Dsource=file:{}'. The file://{} syntax may result in errors creating the wagon file with errors like: "Repository path /openjpa-jdbc-5/target/site/m2-repository does not exist, and cannot be created."

Thursday, 16:00 Update the JIRA versions page to mark the version as "released", and set the date to the date that the release was approved. You may also need to make a new release entry for the subsequent release.

Friday, 16:00

After the mirrors have had time to update (24 hours to be on the safe side), make a news announcement on the OpenJPA wiki.

Once the news item is made, it won't show up on the front page unless you make some minor edit to the containing page (e.g., adding a newline somewhere).

Friday, 16:05 Make an announcement about the release on the [email protected] list (and, for major releases, on the [email protected] list as per the Apache Announcement Mailing Lists page). The announcement might look something like this.

Friday, 16:10 Make an announcement for the freshmeat.net OpenJPA project (optional)

Friday, 17:00 Have a beer and enjoy your weekend while the world's grateful programmers revel in yet another high-quality release of Apache OpenJPA!


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 


 2a 
 Use ssh-keygen to create a SSH key.
 See Authenticating By Public Key (OpenSSH) for a good description on why and how to perform this task.
 


 2b 
 In Windows platform, use PuttyGen to create a SSH key (see Putty help for details). 

	Use "SSH-2 DSA" key type and 1024-bit key size.
	Copy the content of the "Public key for pasting...." and save it to a file named authorized_keys for later use.
	The private key saved by PuTTYGen can only be used in Putty configuration.

 


 3 
 pscp your SSH public key authorized_keys saved in last step to ~/authorized_keys 


 4 
 Use PuTTY to login to people.apache.org 


 5 
 Create a ~\.ssh folder and change its file mode to 700.


 6 
 Move or append ~/authorized_keys to ~/.ssh/authorized_keys and change its file mode to 600.

	Each public key in the authorized_keys spans only one line.
	
		For example: "ssh-dss AAAAB3NzaC1kc3MAAA ..... agBmmfZ9uAbSqA== dsa-key-20071107"
	
	
	'#' in the first column is a comment line.

 


 7 
 Configure putty to use your private key and save the session 
Specify your private key in the "Connection -> SSH -> Auth" category in Putty configuration.





Create a PGP key



 1 
 Install cgywin, including Utils/gnupg and Net/openssh packages, or install gpg from http://www.gnupg.org/(en)/download/index.html 


 2 
 Generate a key-pair with $ gpg --gen-key using default key kind ("DSA and Elgamal") and ELG-E keys size (2048).

	The generated keys are stored in $HOME/.gnupg or %HOME%\Application Data\gnupg subdirectory.
	Save the content in this subdirectory to a safe media. This contains your private key used to sign all the OpenJPA release materials.

 


 3 
 Backup your cygwin home directory to another media 


 4 
 Add your public key to https://svn.apache.org/repos/asf/openjpa/site/docs/KEYS and /www/www.apache.org/dist/openjpa/KEYS. See the commands describe at the beginning of this KEYS file to perform this task. The gpg key-pair is used to sign the published artifacts for the OpenJPA releases. 


 5 
 Following the instructions in http://people.apache.org/~henkp/trust/ and ask someone in the OpenJPA project to sign your public key. 


 6 
 Submit your public key to a key server. E.g. http://pgp.surfnet.nl:11371/ or http://pgp.mit.edu/



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>


$PATH_TO_PRIVATE_KEY is the path to the private key generated for ssh. E.g. /home/yourLocalUserId/.ssh/id_dsa.
 



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 



Troubleshooting

Space Character in Build Root Path



 Description 
 If there are spaces in the path to the build root subdirectory, the maven task uses to generate the revision number for the org.apache.openjpa.revision.properties yields incorrect data. For example:
org.apache.openjpa.revision.properties

revision.number=Type 'svnversion --help' for usage.
openjpa.version=1.0.1

 


 Solution 
 Rename the path and remove all spaces. 



Merging local repository to remote repository in Cygwin/Windows



 Description 
 The "maven-stage-plugin" is very sensitive to the parameters being passed to it, i.e. the source and target URL properties. When this plugin is used under Cygwin, make sure the following practices are used:

	Use absolute path in the find command's root directory. 

Problem symptom:

$ find . -name m2-repository -not -path "*openjpa-project*" \
    -exec mvn -f "c:/tmp/maven-stage-plugin/pom.xml" stage:copy \
    -Dsource=file://{} -Dtarget=scp://[email protected]/www/people.apache.org/repo/m2-ibiblio-rsync-repository \
    -Dversion=1.0.1 \;

       scp://[email protected]/www/people.apache.org/repo/m2-ibiblio-rsync-repository


	Quote and use the drive name in the path.

Problem symptom:

$ find /cygdrive/c/OpenJPA.1.0.1.Release/1.0.1 -name m2-repository -not -path "*openjpa-project*" \
    -exec mvn -f /cygwin/c/tmp/maven-stage-plugin/pom.xml stage:copy \

 Solution 
 As recommended in the descriptions.
For example:

find "c:/OpenJPA.1.0.1.Release/1.0.1" -name m2-repository -not -path "*openjpa-project*" \
    -exec mvn -f "c:/tmp/maven-stage-plugin/pom.xml" stage:copy \
    -Dsource=file://{} \
    -Dtarget=scp://[email protected]/www/people.apache.org/repo/m2-ibiblio-rsync-repository \
    -Dversion=1.0.1 \;

 
 



Cygwin/Windows File Path



 Description 
 For Cygwin/Windows user: file and folder path names using drive identifier (e.g. C:\OpenJPA Release\1.0.1 ) in commands can be expressed as /cygwin/c/OpenJPA Release/1.0.1/. This form of path name specification may have inconsistent and undesirable behaviors.


 Solution 
 Consistently use the following naming conventions:

	Continue to use the Windows form of path name, e.g. C:\a\b\c
	Use '/' instead of '\' character as file separator, e.g. C:/a/b/c
	Quote all path name using '"' character, e.g. "C:/a/b/c"
	Avoid using space characters in path name, e.g. "C:/OpenJPA.Release/1.0.1"







"Too many unapproved licenses:"



 Description 
 Encounter the "Too many unapproved licenses:" message while running the "license-verify-profile" profile in "mvn deploy site..." step. This is caused by extra artifacts in the build tree that the license verification plugin does not recognized. Examples of these artifacts are:

	Eclipse control files, .classpath, .project
	User created log files




 Solution 
 Avoid the followings:

	Don't use Eclipse's svn plugin to "Check out" files to a Eclipse project. Simply use the svn command, as described in the release instructions.
	Don't create, directly or indirectly, any files under the release build tree.
