How to Cut a Software Release¶

This document details the process for releasing new OSG Release version(s). This document does NOT discuss the policy for deciding what goes into a release, which can be found here.

Due to the length of time that this process takes, it is recommended to do the release over three or more days to allow for errors to be corrected and tests to be run.

Requirements¶

User certificate registered with OSG's koji with build and release team privileges
An account on UW CS machines (e.g. library, ingwe) to access UW's AFS
release-tools scripts in your PATH (GitHub)
osg-build scripts in your PATH (installed via OSG yum repos or source)
Access to the tarball repository at UNL ([email protected])

Pick the Version Number¶

The rest of this document makes references to <VERSION(S)> and <NON-UPCOMING VERSIONS(S)>, which refer to a space-delimited list of OSG version(s) and that same list minus upcoming (e.g. 3.3.28 3.4.3 upcoming and 3.3.28 3.4.3). If you are unsure about either the version or revision, please consult the release manager.

Day 0: Generate Preliminary Release List¶

The release manager often needs a tentative list of packages to be released. This is done by finding the package differences between osg-testing and the current release.

Step 1: Update the osg-version RPM¶

For each release (excluding upcoming), update the version number in the osg-version RPM's spec file and build it in koji:

# If building for the latest release out of trunk
osg-build koji osg-version
# If building for an older release out of a branch:
MAJOR_VERSION=<MAJOR VERSION>
osg-build koji --repo=$MAJOR_VERSION osg-version

Where <MAJOR VERSION> is of the format x.y (e.g. 3.2).

Step 2: Promote osg-version and generate the release list¶

Run 0-generate-pkg-list from a machine that has your koji-registered user certificate:

VERSIONS="<VERSION(S)>"

git clone https://github.com/opensciencegrid/release-tools.git
cd release-tools
0-generate-pkg-list $VERSIONS

Day 1: Verify Pre-Release and Generate Tarballs¶

This section is to be performed 1-2 days before the release (as designated by the release manager) to perform last checks of the release and create the client tarballs.

Step 1: Verify Pre-Release¶

Compare the list of packages already in pre-release to the final list for the release put together by the OSG Release Coordinator (who should have updated release-list in git). To do this, run the 1-verify-prerelease script from git:

VERSIONS="<VERSION(S)>"

1-verify-prerelease $VERSIONS

If there are any discrepancies consult the release manager. You may have to tag or untag packages with the osg-koji tool.

Note

Please verify that the osg-version RPM is in your set of packages for the release! Also verify that if there is a new version of the osg-tested-internal RPM, then it is included in the release as well!

Step 2: Test Pre-Release in VM Universe¶

To test pre-release, you will be kicking off a manual VM universe test run from osghost.chtc.wisc.edu.

Ensure that you meet the pre-requisites for submitting VM universe test runs

Prepare the test suite by running:

osg-run-tests -P 'Testing OSG pre-release'

cd into the directory specified in the output of the previous command
Submit the DAG:
```
condor_submit_dag master-run.dag
```

Note

If there are failures, consult the release-manager before proceeding.

Step 3: Test Pre-Release on the Madison ITB site¶

Test the pre-release on the Madison ITB by following the ITB pre-release testing instructions. If you not local to Madison, consult the release manager for the designated person to do this testing.

Step 4: Regenerate the build repositories¶

To avoid 404 errors when retrieving packages, it's necessary to regenerate the build repositories. Run the following script from a machine with your koji-registered user certificate:

NON_UPCOMING_VERSIONS="<NON-UPCOMING VERSION(S)>"

1-regen-repos $NON_UPCOMING_VERSIONS

Step 5: Create the client tarballs¶

Create the client tarballs as root on an EL7 fermicloud machine using the relevant script from git:

NON_UPCOMING_VERSIONS="<NON-UPCOMING VERSION(S)>"

git clone https://github.com/opensciencegrid/release-tools.git
cd release-tools
./1-client-tarballs $NON_UPCOMING_VERSIONS

Step 6: Briefly test the client tarballs¶

As an unprivileged user, extract each tarball into a separate directory. Make sure osg-post-install works. Make sure osgrun osg-version works by running the following tests, replacing <NON-UPCOMING VERSION(S) with the appropriate version numbers:

NON_UPCOMING_VERSIONS="<NON-UPCOMING VERSION(S)>"

./1-verify-tarballs $NON_UPCOMING_VERSIONS

If you have time, try some of the binaries, such as grid-proxy-init.

Todo

We need to automate this and have it run on the proper architectures and version of RHEL.

Step 7: Update the UW AFS installation of the tarball client¶

The UW keeps an install of the tarball client in /p/vdt/workspace/tarball-client on the UW's AFS. To update it, run the following commands:

NON_UPCOMING_VERSIONS="<NON-UPCOMING VERSION(S)>"

for ver in $NON_UPCOMING_VERSIONS; do
    /p/vdt/workspace/tarball-client/afs-install-tarball-client $ver
done

Step 8: Wait¶

Wait for clearance. The OSG Release Coordinator (in consultation with the Software Team and any testers) need to sign off on the update before it is released. If you are releasing things over two days, this is a good place to stop for the day.

Day 2: Pushing the Release¶

Step 1: Push from pre-release to release¶

This script moves the packages into release, clones releases into new version-specific release repos, locks the repos and regenerates them.

VERSIONS="<VERSION(S)>"

2-create-release $VERSIONS

*.txt files are also created and it should be verified that they've been moved to /p/vdt/public/html/release-info/ on UW's AFS.
For each release version, use the *release-note* files to update the relevant sections of the release note pages.

Step 2: Upload the client tarballs¶

Upload the tarballs to the repository with the following procedure from a UW CS machine (e.g., ingwe):

NON_UPCOMING_VERSIONS="<NON-UPCOMING VERSION(S)>"

pushd /p/vdt/public/html/tarball-client
for ver in $NON_UPCOMING_VERSIONS; do
    major_ver="${ver%.*}"
    ssh [email protected] mkdir -p /usr/local/repo/tarball-install/$major_ver/$ver
    scp -p $major_ver/*/osg-wn-client-$ver*gz [email protected]:/usr/local/repo/tarball-install/$major_ver/$ver
done
popd
ssh [email protected] bin/mk-sims.sh
for ver in $NON_UPCOMING_VERSIONS; do
    major_ver="${ver%.*}"
    ssh [email protected] "cd /usr/local/repo/tarball-install; ls -l $major_ver/*latest*"
done
# verify the "latest" symlinks point to the version(s) just installed

Step 3: Install the tarballs into OASIS¶

Note

You must be an OASIS manager of the mis VO to do these steps. Known managers as of 2014-07-22: Mat, Tim C, Tim T, Brian L.

Get the uploader script from Git and run it with osgrun from the UW AFS install of the tarball client you made earlier. On a UW CSL machine:

NON_UPCOMING_VERSIONS="<NON-UPCOMING VERSION(S)>"

cd /tmp
git clone --depth 1 file:///p/vdt/workspace/git/repo/tarball-client.git
for ver in $NON_UPCOMING_VERSIONS; do
    /p/vdt/workspace/tarball-client/current/sys/osgrun /tmp/tarball-client/upload-tarballs-to-oasis $ver
done

The script will automatically ssh you to oasis-login.opensciencegrid.org and give you instructions to complete the process.

Step 4: Remove old UW AFS installations of the tarball client¶

To keep space usage down, remove tarball client installations and symlinks under /p/vdt/workspace/tarball-client on UW's AFS that are more than 2 months old. The following command will remove them:

find /p/vdt/workspace/tarball-client -maxdepth 1 -mtime +60 -name 3\* -ls -exec rm -rf {} \;

Step 5: Update the Docker WN client¶

Update the GitHub repo at opensciencegrid/docker-osg-wn using the update-all script found in opensciencegrid/docker-osg-wn-scripts. This requires push access to the opensciencegrid/docker-osg-wn repo.

Instructions for using the script:

git clone [email protected]:opensciencegrid/docker-osg-wn-scripts.git
git clone [email protected]:opensciencegrid/docker-osg-wn.git
docker-osg-wn-scripts/update-all docker-osg-wn
cd docker-osg-wn
# Verify everything looks fine and run the 'git push' command
# that 'update-all' should have printed

Step 6: Announce the release¶

The following instructions are meant for the release manager (or interim release manager). If you are not the release manager, let the release manager know that they can announce the release.

The release manager writes the a release announcement for each version and sends it out. The announcement should mention a handful of the most important updates. Due to downstream formatting issues, each major change should end at column 76 or earlier. Here is a sample, replace <BRACKETED TEXT> with the appropriate values:

Subject: Announcing OSG Software version <VERSION>

We are pleased to announce OSG Software version <VERSION>!

Changes to OSG <VERSION> include:
- Major Change 1
- Major Change 2
- Major Change 3

Release notes and pointers to more documentation can be found at:

http://www.opensciencegrid.org/docs/release/<SERIES.VERSION>/release-<RELEASE-VERSION>/

Need help? Let us know:

http://www.opensciencegrid.org/docs/common/help/

We welcome feedback on this release!

The release manager uses the osg-notify tool on submit-1.chtc.wisc.edu to send the release announcement using the following command:

$ cd topology
$ git pull
$ python bin/osg-notify --cert your-cert.pem --key your-key.pem \
    --no-sign --type production --message message-file \
    --subject '<EMAIL SUBJECT>' \
    --recipients "[email protected] [email protected] [email protected] [email protected]" \
    --oim-recipients resources --oim-contact-type administrative

Replace <EMAIL SUBJECT> with an appropriate subject for your announcement.

The release manager closes the tickets marked 'Ready for Release' in the release's JIRA filter using the 'bulk change' function. Also set the Fix Versions field to the appropriate value(s) and uncheck the box that reads "Send mail for this update"

Day 3: Update the ITB¶

Now that the release has had a chance to propogate to all the mirrors, update the Madison ITB site by following the yum update section of the Madison ITB document. If you are not local to Madison, consult the release manager for the designated person to do the update. Remember to stop the HTCondor and HTCondor-CE daemons according to the HTCondor pre-release testing instructions. Those daemons will need to be restarted after the upgraode.
