Publishing Offline tags

When Offline is tagged, it needs to be build and published on cvmfs in Muse format. A jenkins build project is used to build prof and debug in parallel. If the build fails, the project will return an error. The output is tarballs that can then be installed on cvmfs.

• go to jenkins mu2e-offline-build-muse project. (Requires an account and a cert in the browser.)
• select "Build with Parameters", enter the tag string, and hit "Build". takes about 45 min.
• When done, select "BUILDTYPE=prof"
• if anything went wrong, select "last build" and look at the console output and the log file
• under artifacts, right click on the tarball and "copy link address"
• log onto the cvmfs machine, and start a transaction
• cd to /cvmfs/mu2e.opensciencegrid.org/Musings/, wget the tarball, extract it (bzipped, use "-j")
• remove tarball
• repeat for the debug tarball
• if needed, repoint the "Offline/current" link to this new tag
  • cd /cvmfs/mu2e.opensciencegrid.org/Musings/Offline
  • rm current
  • ln -s vxx_xx_xx current
• cd ~ and publish the transaction
• once cvmfs is updated, test with

muse setup tag

The script that this project runs is in the codetools repo,

codetools/bin/jenkinsMuseBuild.sh

When the jenkins project is run, it checks out the head of codetools to find the script.

Publishing Production tags

1/2022, we agreed to not publish Production as a standalone Musing since it can't be used without including fcl from an Offline. To recognize this we only build SimJob, with a verison of Production source in the SimJob Musing.

Publishing SimJob

SimJob Musing includes an Offline and Production repo tag. The Offline is usually Muse-linked while the Production tag source is now included in the SimJob Musing. includes an Offline Musing linkeand a Production source. It can serve as the basis for submitting production jobs.

In a scratch area, assuming an Offline tag otag, a Production tag ptag and a targeted SimJob tag tag,

setup mu2e
git clone https://github.com/Mu2e/Production
git -C Production checkout -b temp ptag
muse link Offline otag
muse setup 
muse build
muse tarball -r SimJob/tag

You will get an output tarball. In a second window, in the same directory,

setup mu2e
muse setup -q debug
muse build
muse tarball -r SimJob/tag

Then on the cvmfs installation machine

• log onto the cvmfs machine, and start a transaction
• cd to /cvmfs/mu2e.opensciencegrid.org/Musings/, scp the tarball, extract it (bzipped, use "-j")
• remove tarball
• repeat for the debug tarball
• if needed, repoint the "SimJob/current" link to this new tag
• cd ~ and publish the transaction

Publishing Muse itself

To develop Muse, create a fork in your github account, check it out locally

setup mu2e
git clone git@github.com:<your GitHub username>/Muse

and to use this local code instead of "setup muse" do

export MUSE_DIR=$PWD/Muse
export PATH=$PWD/Muse/bin:$PATH
export MUSE_ENVSET_DIR=$PWD/Muse/config
alias muse="source muse"

now you can add envsets and test them directly (as opposed to the muse/uNNN mechanism). All the scripts should work like a normal Muse UPS setup. Develop and commit, pull and tag changes as in any other github repo. To publish tag,

mkdir products
museInstall.sh tag ./products

the products directory will contain an UPS-installed version tag, and a tarball suitable to uploading to cvmfs artproducts area. This script does not checkout or attempt to confirm that the tag is correct, it is assuming the code is actually equivalent to the tagged code. To make the new version UPS-current, edit the version number into the file under the Muse/current.chain directory on cvmfs. You don't need a debug version because this is UPS, which has a NULL product qualifier. For some reason I started using the version number pattern vN_NN_NN, maybe following art.

Testing Muse

Muse contains a series of tests than can be run by hand or as a Jenkins project (mu2e_muse_test). The script can be accessed with

setup mu2e
mu2eTest.sh -h
