This is Travis CI helper to run particular work only once in matrix.
This is workaround for: travis-ci/travis-ci#929
The main goal of this script to have a single publish when a build has several jobs. Currently the first job is a leader, meaning a node that will do the publishing.
An example .travis.yml shows how to ensure that all_succeeded or all_failed:
#...
script:
- curl -Lo travis_after_all.py https://raw.github.com/dmakhno/travis_after_all/master/travis_after_all.py
after_success:
- python travis_after_all.py https://api.travis-ci.com
- export $(cat .to_export_back)
- |
if [ "$BUILD_LEADER" = "YES" ]; then
if [ "$BUILD_AGGREGATE_STATUS" = "others_succeeded" ]; then
echo "All jobs succeeded! PUBLISHING..."
else
echo "Some jobs failed"
fi
fi
after_failure:
- python travis_after_all.py https://api.travis-ci.com
- export $(cat .to_export_back)
- |
if [ "$BUILD_LEADER" = "YES" ]; then
if [ "$BUILD_AGGREGATE_STATUS" = "others_failed" ]; then
echo "All jobs failed"
else
echo "Some jobs failed"
fi
fi
after_script:
- echo leader=$BUILD_LEADER status=$BUILD_AGGREGATE_STATUS- If other jobs will start late, can be global build timeout (think of passing leader role to others, for example who started last is the leader).
- More flexible leader definition (in matrix not all jobs can publish).
- Have several leaders, according to flavours (e.g. if in matrix slices responsible for platform).
