Local KinKal development with Muse

Initial build

To develop new code in KinKal and call it in Offline you will need to define your own version of KinKal and install it in your own private extension to UPS. You need to do some initial setup in a throwaway shell:

  • create a Muse workDir and cd there
setup mu2e
setup muse
  • checkout your fork of Offline in the muse workdir as you would normally
git clone git@github.com:<your GitHub username>/Offline
cd Offline
git remote add -f mu2e https://github.com/Mu2e/Offline
git checkout -b work_branch mu2e/master
cd ..
  • checkout your fork of KinKal in the muse workdir .The KinKal development model is the same as Offline: start with the head of main, create your own branch, develop and commit to that, and make a PR to KinKal when your development is ready.
git clone git@github.com:<your GitHub username>/KinKal
cd KinKal
git remote add -f mu2e https://github.com/KFTrack/KinKal
git checkout -b work_branch mu2e/main
cd ..
  • checkout tag v0.1.4 of KinKal_to_UPS
git clone https://github.com/Mu2e/KinKal_to_UPS
cd KinKal_to_UPS
git checkout -b work_branch v0.1.4
cd ..
  • setup Muse
muse setup

this puts a root and other products in the environment, which the KinKal build will detect

  • build KinKal according to the instructions in README. make sure to run the test (make test)
mkdir build_profile
cd build_profile
cmake ../KinKal  -DCMAKE_BUILD_TYPE=Release    [or Debug]
make -j 20
make test
cd ..
  • create the directory 'artexternals' in the muse workdir. Copying in the upsfiles makes UPS recognize this area.
mkdir artexternals
rsync -aur /cvmfs/mu2e.opensciencegrid.org/artexternals/.upsfiles artexternals/
  • install this build in artexternals. For version, it can be arbitrary, it shouldn't correspond to an actual tag. It will only be used to point to this artexternals area. IN this case we used the next logical tag, in anticipation of the local development becoming the next version.
KinKal_to_UPS/build -v v0.1.6 -i
  • create an envset that points to your local UPS version of KinKal
    • find the envset recommended for the current Offline
> grep ENVSET Offline/.muse
ENVSET p003
    • copy it locally
mkdir muse
cp $MUSE_ENVSET_DIR/p003 muse/u004
    • edit muse/u004 so that it sets up your local version of KinKal
setup -B KinKal  v00_01_06  -q +${MUSE_BUILD}:+${MUSE_COMPILER_E}:+${MUSE_PYTHON}

At this point, the KinKal is built and UPS-installed locally. Now start a new shell, because we need to setup again, this time with this local build in the environment.

  • create a new shell, and cd to your muse workdir
setup mu2e
setup muse
  • execute the following, to tell UPS to look here first for your products
 export PRODUCTS=${PWD}/artexternals:${PRODUCTS}
  • setup muse, now using the envset you created, which points to your local KinKal installation
muse setup -q u004
  • and build Offline
muse build -j 20

Rebuilding KinKal

assuming you are in a fully setup environment, where you could run the code, for example,

  • edit KinKal as needed
  • rebuild KinKal
cd build_profile
make -j 20
make test
cd ..
  • now re-install this build in the UPS artexternals area, it will overwrite the previous
KinKal_to_UPS/build -v v0.1.6 -i

Returning to the area

  • to return in a new shell, you only need to repeat the setups:
cd workDir
setup mu2e
setup muse
export PRODUCTS=${PWD}/artexternals:${PRODUCTS}
muse setup -q u004

Adding debug build

An environment can only be setup once, so for an process, you must choose one or the other. The steps all follow form the prof build

  • setups. Setup muse in debug. Since you don't have the new KinKal in debug, you can setup root by setting up the published versions
cd workDir
setup muse
muse setup -q debug  (defaults to envset p003)
  • build debug KinKal using the same fake version as for prof
mkdir build_debug
cd build_debug
cmake ../KinKal  -DCMAKE_BUILD_TYPE=Debug
make -j 20
make test
cd ..
KinKal_to_UPS/build -v v0.1.6 -i
  • now that the debug version of the local KinKal product is available, you need to setup in new process to get the full environment
cd workDir
setup mu2e
setup muse
export PRODUCTS=${PWD}/artexternals:${PRODUCTS}
muse setup -q u004:debug


What if you update Offline?

If you update the version of Offline in your working area:

  1. Compare the old and new versions of Offline to see if the version or qualifiers of root have changed.
  2. If they have not, you are done with this section. If they have, then you need to do the following:
  3. Make a new build of KinKal using the modified root and install it in your local artexternals directory.
    1. Hint: you may wish to investigate the -s versionSuffix option in KinKal_to_UPS.
    2. Hint: remember to start a new login session
  4. Follow the instructions in Muse#Maintaining_a_Customized_Setup to update your local muse/uNNN file to select your new build of KinKal.



you may need to rebuild KinKal to match the version of root or used by the new Offline.

Original Notes

To develop new code in KinKal and call it in Offline you will need to define your own version of KinKal and install it in your own private extension to UPS. You need to do some initial setup in a throwaway shell:

  • create a Muse workDir and cd there
  • checkout your fork of Offline in the muse workdir as you would normally
  • checkout your fork of KinKal in the muse workdir .The KinKal development model is the same as Offline: start with the head of main, create your own branch, develop and commit to that, and make a PR to KinKal when your development is ready.
  • checkout tag v0.1.4 of KinKal_to_UPS
  • build KinKal according to the instructions in README. make sure to run the test (make test)
  • create the directory 'artexternals' in the muse workdir
  • execute 'muse setup -q (prof, debug) depending on what you want. Note you can have both builds in the same workdir, but any given shell can be only one or the other.
  • invoke KinKal_to_UPS/build -v your_version -i -b -j10, where your_version is whatever version you want (it is temporary). I have this command saved in a script /mu2e/app/users/brownd/KFTrack/install_KinKal.sh
  • define a user envset in the ./muse directory. mine is /mu2e/app/users/brownd/KFTrack/muse/u002 The name is unimportant. Edit that so it refers to your_version of KinKal

Then, close that shell. From then on, you can work with KinKal and/or Offline in this muse workdir with the following commands:

  • create a new shell, and cd to your muse workdir
  • exectue 'export PRODUCTS=${PWD}/artexternals:${PRODUCTS}' This tells UPS to look for KinKal in your local install
  • execute 'muse setup -q (prof, debug) your_envset'

(I have these defined as /mu2e/app/users/brownd/KFTrack/setup_prof.sh and setup_debug.sh in my area)'

  • Any time you change KinKal rebuild and rerun the tests, and then rerun install_KinKal.sh
  • Any time you change Mu2eKinKal (or after changing and rebuilding KinKal as above) rebuild Offline using 'muse build'
