From 274bfa7f28fea96fafa114f2508ebef53735d7b6 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Tue, 3 Oct 2023 16:30:55 -0400 Subject: [PATCH] commit-graph: free write-context entries before overwriting When writing a split graph file, we replace the final element of the commit_graph_hash_after and commit_graph_filenames_after arrays. But since these are allocated strings, we need to free them before overwriting to avoid leaking the old string.
