From 826f0e33ab0cbe976af02dd487303e4d1a0b3017 Mon Sep 17 00:00:00 2001 From: Taylor Blau Date: Mon, 24 Apr 2023 18:20:17 -0400 Subject: [PATCH] t/helper/test-hashmap.c: avoid using `strtok()` Avoid using the non-reentrant `strtok()` to separate the parts of each incoming command. Instead of replacing it with `strtok_r()`, let's instead use the more friendly pair of `string_list_split_in_place()` and `string_list_remove_empty_items()`.
