From: Jonathan Tan Date: Fri, 29 Sep 2017 20:11:45 GMT Subject: [PATCH 09/18] gc: do not repack promisor packfiles Message-ID: <75be6a3b191753d14c5e10caf24ecf6926a7f544.1506714999.git.jonathantanmy@google.com> In-Reply-To: Teach gc to stop traversal at promisor objects, and to leave promisor packfiles alone. This has the effect of only repacking non-promisor packfiles, and preserves the distinction between promisor packfiles and non-promisor packfiles.
