I'm not yet sure about the workspace caching. Does it work as expected? As far as I can see:
- First you restore the
upstream_wscache (if available). I hope this also restore file timestamps. - Next,
industrial_ciupdates fromUPSTREAM_WORKSPACE. Hopefully, this doesn't touch files if they didn't change. Otherwise the cache would be useless.
I believe it does work. It seems to reduce the time to test this package by about half. |

For context, before this caching a CI run of this on ros2 takes about 11min, with this it takes about 4.5min. |
|
For what it's worth, I started this as a way to quickly iterate on this idea as a way to speed up builds for moveit/moveit2. I'll clean this up when I'm satisfied with it and make it a PR here, although I'm not sure if the time difference here really matters. |
Sure. I was assuming that you take this repo as a quick-turnaround sandbox for your CI experiments. |
|
I created this: moveit/moveit#2559 to show my current progress on moveit/moveit2. The newest issue I'm encountering is with running out of disk space in codecov test runs. Unfortunately that's not something I can do with this small repo. I'll clean this up and merge it. The clang-tidy script solution can nicely be tested locally so that one should be easy to do without having to use CI runs in the loop. |

Please don't mix in json syntax here (even though yaml is a superset of json). This reads much better (and is consistent) with the formatting of the remaining file:
env:
- ROS_DISTRO: ...
ROS_REPO: ...
- IMAGE: ...
| uses: pat-s/always-upload-cache@v2.1.3 | ||
| with: | ||
| path: ${{ env.BASEDIR }}/target_ws | ||
| key: target_ws-${{ env.CACHE_PREFIX }}-${{ hashFiles('**/CMakeLists.txt') }}-${{ hashFiles('**/package.xml') }}-${{ github.run_id }} |

You can hash multiple file patterns at once: https://docs.github.com/en/actions/reference/context-and-expression-syntax-for-github-actions#example-with-multiple-patterns
${{ hashFiles('**/CMakeLists.txt', '**/package.xml') }}

This is an attempt to use the caching features of GitHub Actions to further speed up builds by caching entire workspaces.
