Gitlab-ci-multi-runner 9.0 hangs after update on a shell executor.

Summary

After updating to latest gitlab-ce 9.0.0 and gitlab-runner-9.0, pipeline jobs on shell executor started to hangs forever with warn message in syslogs of the gitlab-runner host. This was working fine earlier with gitlab-multi-runner 1.11.1. To resolve this we had to downgrade gitlab-ci-multi-runner from 9.0.0 to 1.11.1. upon downgrade it works well as expected.

Steps to reproduce

• configure a gitlab-ci-multi-runner 1.11.1 shell executor along with gitlab-8.17.1,

• Verify that pipeline runs as expected.

• once the pipeline is set and works as expected, upgrade both gitlab-ce to 9.0.0 and multi-runner to 9.0.0.

• try to execute a job. This is result in gitlab runner hanging forever.

Actual behavior

pipeline job hangs forever and nothing is observed in git-lab coordinator

Expected behavior

Job should be running and logs to appear in gitlab coordinator

Environment description

GitLab information Version: 9.0.0 Revision: cf020e6

Custom Installation. Ubuntu 14 LTS, with gitlab -9.0.0 and gitlab-ci-multi-runner-9.0 with Shell executor.

Used GitLab Runner version

Version: 9.0.0 Git revision: 08a9e6f Git branch: 9-0-stable GO version: go1.7.5 Built: Wed, 22 Mar 2017 16:29:52 +0000 OS/Arch: linux/amd64

Same problem on Docker executor. It is because of after_script section.

after_script: 
  - "echo 'after script placeholder'"

Hotfix: move your after_script to some different section like end of script...

The same problem as discussed here: gitlab-org/gitlab-ci-multi-runner#2271. Needs a fix in GitLab, which was merged today (gitlab-org/gitlab-ce!10185). Fix should be released with GitLab 9.0.1.

I'm closing this as a duplicate :)

Thanks @tmaczukin

GitLab CE/EE 9.0.1 is out so problem of after_script should be resolved now :)
