From c45841fff8f444cc61cecd42e5d2032844ecbe24 Mon Sep 17 00:00:00 2001 From: Taylor Blau Date: Mon, 10 Jul 2023 17:12:33 -0400 Subject: revision.h: store hidden refs in a `strvec` In subsequent commits, it will be convenient to have a 'const char **' of hidden refs (matching `transfer.hiderefs`, `uploadpack.hideRefs`, etc.), instead of a `string_list`. Convert spots throughout the tree that store the list of hidden refs from a `string_list` to a `strvec`. Note that in `parse_hide_refs_config()` there is an ugly const-cast used to avoid an extra copy of each value before trimming any trailing slash characters. This could instead be written as: ref = xstrdup(value); len = strlen(ref); while (len && ref[len - 1] == '/') ref[--len] = '\0'; strvec_push(hide_refs, ref); free(ref); but the double-copy (once when calling `xstrdup()`, and another via `strvec_push()`) is wasteful.
