Proposed change

Pi-hole v6 app passwords can successfully authenticate against /api/auth, but Home Assistant could still reject them during config flow because API version detection intentionally authenticated with an invalid password immediately before validating the real credential.

This changes Pi-hole v6 detection to use /api/info/version instead of an invalid /api/auth attempt. The detection accepts both v6 response shapes:

  • 401 unauthorized JSON when authentication is enabled
  • 200 version JSON when authentication is disabled

This also creates Pi-hole v6 client sessions with an isolated DummyCookieJar, so Pi-hole session cookies do not interfere with SID-header-based v6 authentication.

Type of change

  • Dependency upgrade
  • Bugfix (non-breaking change which fixes an issue)
  • New integration (thank you!)
  • New feature (which adds functionality to an existing integration)
  • Deprecation (breaking change to happen in the future)
  • Breaking change (fix/feature causing existing functionality to break)
  • Code quality improvements to existing code or addition of tests

Hello @headdirt,

When attempting to inspect the commits of your pull request for CLA signature status among all authors we encountered commit(s) which were not linked to a GitHub account, thus not allowing us to determine their status(es).

The commits that are missing a linked GitHub account are the following:

Unfortunately, we are unable to accept this pull request until this situation is corrected.

Here are your options:

  1. If you had an email address set for the commit that simply wasn't linked to your GitHub account you can link that email now and it will retroactively apply to your commits. The simplest way to do this is to click the link to one of the above commits and look for a blue question mark in a blue circle in the top left. Hovering over that bubble will show you what email address you used. Clicking on that button will take you to your email address settings on GitHub. Just add the email address on that page and you're all set. GitHub has more information about this option in their help center.

  2. If you didn't use an email address at all, it was an invalid email, or it's one you can't link to your GitHub, you will need to change the authorship information of the commit and your global Git settings so this doesn't happen again going forward. GitHub provides some great instructions on how to change your authorship information in their help center.

    • If you only made a single commit you should be able to run
      git commit --amend --author="Author Name <email@address.com>"
      
      (substituting "Author Name" and "email@address.com" for your actual information) to set the authorship information.
    • If you made more than one commit and the commit with the missing authorship information is not the most recent one you have two options:
      1. You can re-create all commits missing authorship information. This is going to be the easiest solution for developers that aren't extremely confident in their Git and command line skills.
      2. You can use this script that GitHub provides to rewrite history. Please note: this should be used only if you are very confident in your abilities and understand its impacts.
    • Whichever method you choose, I will come by to re-check the pull request once you push the fixes to this branch.

We apologize for this inconvenience, especially since it usually bites new contributors to Home Assistant. We hope you understand the need for us to protect ourselves and the great community we all have built legally. The best thing to come out of this is that you only need to fix this once and it benefits the entire Home Assistant and GitHub community.

Thanks, I look forward to checking this PR again soon! ❤️

Pull request overview

Fixes Pi-hole v6 app password authentication failures in the Home Assistant Pi-hole integration by changing how v6 is detected and by isolating v6 authentication from cookie-based sessions.

Changes:

  • Switch Pi-hole v6 detection to probe /api/info/version (handling both 200 and 401 JSON shapes) instead of attempting an auth with an intentionally invalid password.
  • Create Pi-hole v6 API clients with a DummyCookieJar to avoid session cookies interfering with SID-header-based v6 authentication.
  • Add/extend tests covering v6 detection responses and v6 config-flow authentication using an app password.

"""Determine the API version of the Pi-hole instance without requiring authentication.

Neither API v5 or v6 provides an endpoint to check the version without authentication.
Version 6 provides other enddpoints that do not require authentication, so we can use those to determine the version
version 5 returns an empty list in response to unauthenticated requests.
Version 6 returns a distinct unauthorized error from its API endpoints, so we can use those to determine the version.
Version 5 returns an empty list in response to unauthenticated requests.
