Someone pointed out strange behavior which I cannot find documented
If you add in the .gitlab-ci.yml file a variable named DEBUG it changes the behavior of uploading artifacts:
DEBUG=1 see [pages (#1483671074) · Jobs · Peter Tillemans / test_debug_flag · GitLab](example build 1 )
adds 2 mysterious lines
DEBUG=2 or higher
uploading is disabled:
Uploading artifacts for successful job00:00
23Missing /usr/bin/gitlab-runner-helper. Uploading artifacts is disabled.
24Cleaning up file based variables00:01
I cannot find a reference in the documentation to this behavior and all similar environment variables are prefixed and not raw as just DEBUG.
I made a small project to illustrate the behavior.
Can someone point me to the relevant documentation?
