Description

So I have the same issue as #556 but for file provider.

I have "DIUN_WATCH_FIRSTCHECKNOTIF=false" and my file provider looks like this:

- include_tags:
  - ^\d+\.\d+\.\d+$
  max_tags: 5
  name: syncthing/syncthing:1.26.0@sha256:6be23b06ef9bc134028d285bb649a2a5d544e5817f0961abb2476a42deaab0e4
  notify_on:
  - new
  sort_tags: semver
  watch_repo: true
- include_tags:
  - ^\d+\.\d+\.\d+$
  max_tags: 5
  name: restic/restic:0.16.0@sha256:78ccbaddf039176457aabaa4b2f4a67aa177535f7e1a656dcfde18b2d6c2441d
  notify_on:
  - new
  sort_tags: semver
  watch_repo: true

Expected behaviour

Diun only notifies about tags that are newer than the current tags.

Actual behaviour

Diun notifies all tags regardless they are newer than the current tags or not.

Steps to reproduce

1. Run diun with file provider as above.

Diun version

4.26.0

Additional info

It seems that diun will notify max_tags (in my case: 5) latest tags that matches the include_tags without checking that if it is newer than the tag in the current file provider. I only want it to notify about the newer tags than my current stack.

We don't support semver comparison atm but I guess that could be a new field like:

-
  include_tags:
    - ^\d+\.\d+\.\d+$
  max_tags: 5
  semver:
    - > 1.26.0
