From 829a321569d8e8f2c582aef9f0c990df976ab842 Mon Sep 17 00:00:00 2001 From: Derrick Stolee Date: Mon, 20 Aug 2018 18:24:34 +0000 Subject: [PATCH] commit-graph: close_commit_graph before shallow walk Call close_commit_graph() when about to start a rev-list walk that includes shallow commits. This is necessary in code paths that "fake" shallow commits for the sake of fetch. Specifically, test 351 in t5500-fetch-pack.sh runs git fetch --shallow-exclude one origin with a file-based transfer. When the "remote" has a commit-graph, we do not prevent the commit-graph from being loaded, but then the commits are intended to be dynamically transferred into shallow commits during get_shallow_commits_by_rev_list(). By closing the commit-graph before this call, we prevent this interaction.
