Child pipeline artifacts cannot be downloaded via ref-based links
Summary
Artifacts from jobs in child pipelines cannot be downloaded via the instructions in the docs, e.g.:
Steps to reproduce
- Create a child pipeline containing a job that generates artifacts.
- Attempt to download artifact from the "child job".
Example Project
I've created a scratch repo/pipeline to demonstrate this:
https://gitlab.com/rsrchboy/scratch/commits/child-artifacts
The parent and child pipelines both contain jobs that generate artifacts.
What is the current bug behavior?
The latest artifacts from the job in the parent pipeline can be downloaded, e.g.:
$ curl --location https://gitlab.com/rsrchboy/scratch/-/jobs/artifacts/child-artifacts/raw/artifacty\?job\=build-parent
I am the model of a modern major general...while they cannot from the child pipeline:
$ curl -v https://gitlab.com/rsrchboy/scratch/-/jobs/artifacts/child-artifacts/raw/admiralty.txt\?job\=build-child
<...snip...>
> GET /rsrchboy/scratch/-/jobs/artifacts/child-artifacts/raw/admiralty.txt?job=build-child HTTP/1.1
> Host: gitlab.com
> User-Agent: curl/7.67.0
> Accept: */*
<...snip...>
< HTTP/1.1 404 Not Found
<...snip...>What is the expected correct behavior?
I'd expect the artifact from the child job to be fetched in the same fashion as the artifact in the parent job:
$ curl --location https://gitlab.com/rsrchboy/scratch/-/jobs/artifacts/child-artifacts/raw/admiralty.txt\?job\=build-child
I am the monarch of the seaRelevant logs and/or screenshots
Logs, etc, can all be found in the pipelines at:
- https://gitlab.com/rsrchboy/scratch/commits/child-artifacts
- rsrchboy/scratch@2aeb1b7b
- https://gitlab.com/rsrchboy/scratch/pipelines/114604557
Output of checks
This bug happens on GitLab.com.
Proposal
There is a proposal MR !29710 (merged) that describes the direction we can take to solve this problem. It needs to be completed.
