KinKal

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/Offline
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
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

=Rebuilding KinKal

assuming you are in an environment where you could run the code,

• 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

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

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'
