From f503bb7dc96ee92623ade8d60eed401ecfddae0f Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Mon, 23 Feb 2026 12:59:43 +0100 Subject: refs: generalize `refs_for_each_fullref_in_prefixes()` The function `refs_for_each_fullref_in_prefixes()` can be used to iterate over all references part of any of the user-provided prefixes. In contrast to the `prefix` parameter of `refs_for_each_ref_ext()` it knows to handle the case well where multiple of the passed-in prefixes start with a common prefix by computing longest common prefixes and then iterating over those. While we could move this logic into `refs_for_each_ref_ext()`, this one feels somewhat special as we perform multiple iterations. But what we _can_ do is to generalize how this function works: instead of accepting only a small handful of parameters, we can have it accept the full options structure. One obvious exception is that the caller must not provide a prefix via the options. But this case can be easily detected. Refactor the code accordingly.
