Codecov CI action fails on PRs from forks

[emersonknapp]

Description

When a Pull Request comes in from a fork, it can't access the secret codecov token, so the CI fails to upload codecov results and returns a failure. This was observed here: #131

Latest news is that there is a GitHub Actions API released today, and the codecov action is working to implement a solution - see codecov/codecov-action#29

For now, this issue can track that progress.

Expected Behavior

• PRs from forks can upload codecov results

Actual Behavior

• PRs from forks fail CI on the tasks that try to upload to codecov

To Reproduce

• Open a PR from a fork of this repo

System (please complete the following information)

N/A

Additional context

Codecov is working on "Tokenless uploads" https://community.codecov.io/t/whitelist-github-action-servers-to-upload-without-a-token/491/15

This is true for all repos using action-ros-ci. Similar issue: ros-tooling/action-ros-ci#56.

[emersonknapp]

According to codecov/codecov-action#29 (comment) we should have some option available in the next week or so.

Codecov action "tokenless uploads" have been enabled - check if it works

This is now working - see report on #171 - accurately reported reduced coverage
