## OpenACS Core and .LRN

1. Update Translations. How to Update the translations

2. Rebuild the Changelog. Rebuild the Changelog. I use a tool called cvs2cl. Run this command from the package root to automatically generate a Changelog file in the same dir. We generate two changelogs, one for the minor branch and one for the most recent release. The example below is for OpenACS 5.0.2:

       cd /var/lib/aolserver/$OPENACS_SERVICE_NAME
       cvs2cl -F oacs-5-0 --delta openacs-5-0-0-final:oacs-5-0 -f ChangeLog
       cvs2cl -F oacs-5-0 --delta openacs-5-0-1-final:oacs-5-0 -f ChangeLog-recent

3. Update Version Numbers. The version numbers in the documentation and in the packages must be updated. This should only happen after a release candidate is approved.

   .LRN: this must be repeated for .LRN modules (dotlrn-core in the dotlrn cvs tree) and for any modified modules in the .LRN prerequisites (dotlrn-prereq in openacs cvs tree). My current working model is that I bulk-update .LRN and OpenACS core but that I don't touch dotlrn-prereq modules - I just use the most recent release and it's up to individual package developers to tag and release those packages when they change. This model is already broken because following it means that dotlrn-prereqs don't get new translations.

   1. Update /var/lib/aolserver/$OPENACS_SERVICE_NAME/packages/acs-core-docs/www/xml/variables.ent with the new version number.

   2. Add new section in /var/lib/aolserver/$OPENACS_SERVICE_NAME/packages/acs-core-docs/www/xml/for-everyone/release-notes.xml

   3. Regenerate all HTML docs

          cd /var/lib/aolserver/$OPENACS_SERVICE_NAME/packages/acs-core-docs/www/xml
          make

   4. Update /var/lib/aolserver/$OPENACS_SERVICE_NAME/readme.txt with the new version number

   5. Update version number and release date in all of the core packages. Use /var/lib/aolserver/$OPENACS_SERVICE_NAME/packages/acs-core-docs/www/files/update-info.sh with the new version number and the release date as arguments. Run it from /var/lib/aolserver/$OPENACS_SERVICE_NAME/packages:

          cd /var/lib/aolserver/$OPENACS_SERVICE_NAME/packages
                 ./acs-core-docs/www/files/update-info 5.2.1 2006-01-16

   6. Install a new site using the modified code and verify that the automated tests pass.

   7. Commit changes to CVS

4. Tag the files in CVS. The steps to this point should have ensured that the head of the current branch contains the full set of code to release. Now we need to tag it as the code to be released.

   1. Check out OpenACS Core. The files must be checked out through a cvs account with write access and should be a checkout from the release branch. In this example, we are assuming this is being done as a local user on openacs.org (which make the checkout and tagging operations much faster).

          cd /var/tmp
          cvs -d /cvsroot checkout -r oacs-5-0 acs-core

      If doing .LRN, repeat with the dotlrn cvs tree.

          cd /var/tmp
          mkdir dotlrn-packages
          cd dotlrn-packages
          cvs -d /dotlrn-cvsroot checkout -r dotlrn-2-0 dotlrn-all

   2. Tag the tree. If it's a final release of core, move or create the appropriate openacs-major-minor-compat tag. (Ie, if releasing 5.0.3 final, move the openacs-5-0-compat flag.)

          cd /var/tmp/openacs-4
          cvs tag -F openacs-5-0-0a1
          cvs tag -F openacs-5-0-compat

      ### Branching

      When we feature-freeze on HEAD as part of the release process, we are blocking new development. To avoid this, we branch the code at this point, so that new work can continue on HEAD while the branch is stabilized for release. However, branching means that bug fixes have to be synchronized between HEAD and the branch, and bug fixes tend to be more frequent right at this time. Therefore, our actual branch point is as late as possible - essentially, we do not branch until and unless new feature work is actively blocked by the feature freeze. Branching is almost the same as tagging, except for the flag and slightly different tag nomenclature. To see the list of old branches, `cvs status -v somefile`.

          cvs tag -b oacs-5-0

      If doing .LRN: Since the .LRN packages aren't all in one module, we iterate through all of the modules. Log in first (cvs login) so that you don't have to log in for each module.

          cd /var/tmp/dotlrn-packages
          for dir in *; do ( cd $dir && cvs tag dotlrn-2-0-2-final ); done
          for dir in *; do ( cd $dir && cvs tag -F openacs-5-0-compat ); done

      Note that for the compat tag we use the -F flag which will force the tag to the new version (just in case someone has created the tag already on another version). Excercise care when doing this since you don't want to inadvertently move a prior release tag. Also if the tagging goes horribly wrong for some reason you can delete the tag via "cvs tag -d <symbolic_tag>".

   3. Apply the `final` tag across the tree. First, check out the entire OpenACS tree, getting the most recent stable version of each package. This is most simply done on openacs.org:

          cd /var/tmp
          cvs -d /cvsroot checkout -r openacs-5-1-compat openacs-4
          cd openacs-4
          cvs tag openacs-5-1-2-final

5. Make the tarball(s).

   - openacs-core.

     1. Go to a new working space and export the tagged files.

            mkdir /var/tmp/tarball
            cd /var/tmp/tarball
            cvs -d /cvsroot export -r openacs-5-0-0a1 acs-core

     2. Generate the tarball.

            cd /var/tmp/tarball
            mv openacs-4 openacs-5.0.0a1
            tar cz -f openacs-5.0.0a1.tar.gz openacs-5.0.0a1

   - dotlrn.

     1. Go to a new working space and export the tagged files. (was getting errors here trying to use -d, so gave up and just moved things from openacs-4 to openacs at the end)

            mkdir /var/tmp/dotlrn-tarball
            cd /var/tmp/dotlrn-tarball
            cvs -d /cvsroot export -r openacs-5-0-0a1 acs-core
            cd /var/tmp/dotlrn-tarball/openacs-4/packages
            cvs -d /cvsroot export -r openacs-5-0-0a1 dotlrn-prereq
            cvs -d /dotlrn-cvsroot export -r dotlrn-2-0-0a1 dotlrn-core

     2. Copy the dotlrn install.xml file, which controls which packages are installed on setup, to the root location:

            cp /var/tmp/dotlrn-tarball/openacs-4/packages/dotlrn/install.xml \
               /var/tmp/dotlrn-tarball/openacs-4

     3. Generate the tarball

            cd /var/tmp/dotlrn-tarball
            mv openacs-4 dotlrn-2.0.0a1
            tar cz -f dotlrn-2.0.0a1.tar.gz dotlrn-2.0.0a1

6. Test the new tarball(s). Download the tarballs just created and install them and make sure everything looks okay and that automated tests pass.

7. Update Web site. Update the different places on OpenACS.org where we track status.

   - Release Status for the current version - something like http://openacs.org/projects/openacs/5.0/milestones

   - Home page of openacs.org

   - Post a new news item

8. Clean Up. Clean up after yourself.

       cd /var/tmp
       rm -rf tarball dotlrn-tarball dotlrn-packages openacs-5.0.0a1
       rm -rf /var/tmp/openacs-4

Here is a shell script that automates packaging the tarball (it's a bit out of date with the new steps - I've been doing everything manually or with little throwaway scripts as detailed above until the process is stabilized).

    #!/bin/bash

    # if TAG=1 create the cvs tags otherwise assume they exist.
    TAG=1

    # What release version are we building; version format should be
    # dashes rather than dots eg. OACS_VERSION=5-0-0b4

    OACS_VERSION=5-0-0b4
    DOTLRN_VERSION=2-0-0b4

    OACS_BRANCH=oacs-5-0
    DOTLRN_BRANCH=dotlrn-2-0

    DOTLRN_CVSROOT=/dotlrn-cvsroot
    OACS_CVSROOT=/cvsroot

    #
    BASE=/var/tmp/release-$OACS_VERSION
    mkdir $BASE
    if [ ! -d $BASE ]; then
        echo "Failed creating base dir $BASE"
        exit 1
    fi

    cd $BASE

    if [ $TAG -eq 1 ]; then

        # Checkout and tag the release
        cvs -d $OACS_CVSROOT checkout -r $OACS_BRANCH openacs-4
        cd openacs-4
        cvs tag -F openacs-$OACS_VERSION
        cd ../

        # Checkout and tag the dotlrn release
        mkdir dotlrn-packages
        cd dotlrn-packages
        cvs -d $DOTLRN_CVSROOT checkout -r $DOTLRN_BRANCH dotlrn-all
        for dir in *; do ( cd $dir && cvs tag -F dotlrn-$DOTLRN_VERSION ); done
        cd ../

        #
        # Should check for .sql .xql .adp .tcl .html .xml executable files and squak if found.
        #

    fi

    # Generate tarballs...
    #

    # openacs
    #
    mkdir tarball
    cd tarball
    cvs -d $OACS_CVSROOT export -r openacs-$OACS_VERSION acs-core
    mv opeancs-4 openacs-${OACS_VERSION//-/.}
    tar -czf ../openacs-${OACS_VERSION//-/.}.tar.gz openacs-${OACS_VERSION//-/.}
    cd ..

    # dotlrn
    #
    mkdir dotlrn-tarball
    cd dotlrn-tarball
    cvs -d $OACS_CVSROOT export -r openacs-$OACS_VERSION acs-core
    cd  openacs-4/packages
    cvs -d $OACS_CVSROOT export -r openacs-$OACS_VERSION dotlrn-prereq
    cvs -d $DOTLRN_CVSROOT export -r dotlrn-$DOTLRN_VERSION dotlrn-core
    cd ../..
    cp -f openacs-4/packages/dotlrn/install.xml openacs-4
    mv openacs-4 dotlrn-${DOTLRN_VERSION//-/.}
    tar -czf ../dotlrn-${DOTLRN_VERSION//-/.}.tar.gz dotlrn-${DOTLRN_VERSION//-/.}

    # Clean up after ourselves...
    cd $BASE && rm -rf dotlrn-tarball tarball openacs-4 dotlrn-packages
