From: René Scharfe Date: Sun, 09 Feb 2025 10:41:15 GMT Subject: [PATCH] commit: avoid parent list buildup in clear_commit_marks_many() Message-ID: <16a7b572-0a3d-4707-9034-0dac69ea99ac@web.de> clear_commit_marks_1() clears the marks of the first parent and its first parent and so on, and saves the higher numbered parents in a list for later. There is no benefit in keeping that list growing with each handled commit. Clear it after each run to reduce peak memory usage.
