Watching vdsm travis builds in the last weeks, it is clear that vdsm tests
on travis are about 4X times faster compared with jenkins builds.
Here is a typical build:
travis ci: https://travis-ci.org/nirs/vdsm/builds/179056079
The build took 4:34 on travis, and 19:34 on ovirt ci.
This has a huge impact on vdsm maintainers. Having to wait 20 minutes
for each patch
means that we must ignore the ci and merge and hope that previous tests without
rebasing on master were good enough.
The builds are mostly the same, expect:
- In travis we don't check if the build system was changed and
packages should be built
takes 9:18 minutes in ovirt ci.
- In travis we don't clean or install anything before the test, we use
a container with all the
available packages, pulled from dockerhub.
takes about 3:52 minutes in ovirt ci
- In travis we don't enable coverage. Running the tests with coverage
may slow down the tests
takes 5:04 minutes in ovirt ci
creating the coverage report takes only 15 seconds, not interesting
- In travis we don't cleanup anything after the test
this takes 34 seconds in ovirt ci
The biggest problem is the build system check taking 9:18 minutes.
fixing it will cut the build time in half.
This is how time is spent in ovirt ci:
