git branch †

http://www.backlog.jp/git-guide/reference/branch.html

git cherry-pick †

https://teratail.com/questions/297

# Apply changes of branch A to branch B
git branch
git checkout A
git log
# check commit hash xxxxx
git checkout B
git cherry-pick xxxxxx
# git diff shows nothing
git push --set-upstream origin B

変更をhttps://gitlab.cern.ch/atlas/athena/に反映させる †

https://atlassoftwaredocs.web.cern.ch/gittutorial/merge-request/
に従って、Merge Requestを行う。
https://gitlab.cern.ch/atlas/athena/merge_requests/924
みたいなのができて、自動的にContinuous Integration (CI)が始まる。

RunTier0Tests.py †

cd ../build
asetup Athena 21.0 r2017-04-19
cmake -DATLAS_PACKAGE_FILTER_FILE=../package_filters.txt ../athena/Projects/WorkDir
make -j
cd ../
export TestArea=$PWD
cd ./run
source ../build/x86_64-slc6-gcc62-opt/setup.sh
RunTier0Tests.py

コンフリクトした場合 †

https://gitlab.cern.ch/atlas/athena/merge_requests/5357 のコンフリクトは、これで解決できた。

git fetch https://:@gitlab.cern.ch:8443/oda/athena.git master-SCT_ReadCalibDataSvc 
# git checkout -b master-SCT_ReadCalibDataSvc FETCH_HEAD
# Skipped because I have the branch already.
git pull
git fetch upstream
git merge upstream/master
# nano editor will be opened.
# Fix conflicts
git push https://:@gitlab.cern.ch:8443/oda/athena.git master-SCT_ReadCalibDataSvc
