Using renovate to run copier updates

[sbidoul]

Renovate has the capability to run copier update .

I'm currently experimenting with a per repo config like this, which needs to be defined on the main branch of each repo.

We'd need to self-host renovate, either on the OCA server, or using a org-wide scheduled GitHub action, because our copier template needs --trust. Need to think about the security implications.

WIth a renovate config like this

{
  "plaform": "github",
  "allowScripts": true,
  "autodiscover": false,
  "repositories": [
    "OCA/mis-builder"
  ],
  "username": "oca-renovate-bot",
  "gitAuthor": "oca-renovate-bot <oca-renovate-bot@odoo-community.org>"
}

it produced pull requests such as OCA/mis-builder#763, OCA/mis-builder#767, OCA/mis-builder#768.

To be continued....

because our copier template needs --trust

I think none of the tasks actually make sense these days and could be removed, so --trust can be removed too.

The unsafe tasks are removal of obsolete files:

_tasks:
  - rm -f {% if ci != "Travis" %}.travis.yml{% endif %} .t2d.yml
  - "{% if odoo_version >= 18 %}rm -f .prettierrc.yml .eslintrc.yml{% endif %}"

_migrations:
  - version: v1.3.6
    after:
      - rm -f CONTRIBUTING.md

Some are important.

We could add a pre-commit fail entry on such files so maintainers have to remove them manually.

Or, @yajo, do you know if there is something in copier to delete files without --trust?

[yajo]

Since Copier 6, removal of files that disappeared in the template is automatic. Relevant commit: copier-org/copier@23dd5db

Also, --trust is only needed in migrations that pass through that specific template update.

The template requires Copier 9:

oca-addons-repo-template/copier.yml

Line 4 in 38b45f6

_min_copier_version: "9"

So, in short, you can just remove all that code today 😉

The sun in Santander gave me some motivation, so the public renovate bot is now making PRs on MIS Builder: https://github.com/OCA/mis-builder/pulls/app%2Frenovate 🥳

I now plan to update the project template to add a renovate.json and see how it scales.
