Copier manager does not preserve executable bit on updated files

[rlee4advancelocal]

Self-hosted Renovate CLI

Please tell us more about your question or problem

We are attempting to use the copier manager to update copier but notice the execution bit is lost on changed and new files.
Using copier locally to update does not cause the execution bit to be lost.
We think this is related to how renovate may be tracking execution bits to files copier updates.

Hi there,

Please help this Discussion progress by creating a minimal reproduction. This means a repository dedicated to reproducing this issue with the minimal dependencies and config possible.

Before we start working on your issue we need to know exactly what's causing the current behavior. A minimal reproduction helps us with this. Discussions without reproductions are less likely to be converted to Issues.

Please follow these steps:

1. Read our guide on creating a minimal reproduction.
2. Go to our minimal reproduction template repository.
3. Select the Use this template button to create a new repository based on the template.
4. Work on the reproduction in your own repository. Ensure it's actually minimal (no unnecesary dependencies or config), or it will be rejected by maintainers.
5. Install the Renovate app to verify that what you say happens (or doesn't happen) reproduces.
6. Fill out the information in your repository's README.md. What you describe there should reflect what you see in this repo, with the hosted app, and not what you saw in your original repo/environment.
7. Add the link to your reproduction to the first post of your Discussion. If you are not the original author, you can post a new comment with the link.
8. Add a Discussion comment mentioning that the reproduction repo is now available and linked.

If you need help with running Renovate on your minimal reproduction repository, please refer to our Running Renovate guide.
Good luck,

The Renovate team

This would be very helpful for us to be able to debug / triage further :)

Hello,

I created https://github.com/rlee4advancelocal/41438 to reproduce the issue. I was able to use the hosted Renovate service for github.com to reproduce.
