fetch-pack: support more than one pack lockfile
Whenever a fetch results in a packfile being downloaded, a .keep file is generated, so that the packfile can be preserved (from, say, a running "git repack") until refs are written referring to the contents of the packfile. In a subsequent patch, a successful fetch using protocol v2 may result in more than one .keep file being generated. Therefore, teach fetch_pack() and the transport mechanism to support multiple .keep files. Implementation notes: - builtin/fetch-pack.c normally does not generate .keep files, and thus is unaffected by this or future changes. However, it has an undocumented "--lock-pack" feature, used by remote-curl.c when implementing the "fetch" remote helper command. In keeping with the remote helper protocol, only one "lock" line will ever be written; the rest will result in warnings to stderr. However, in practice, warnings will never be written because the remote-curl.c "fetch" is only used for protocol v0/v1 (which will not generate multiple .keep files). (Protocol v2 uses the "stateless-connect" command, not the "fetch" command.) - connected.c has an optimization in that connectivity checks on a ref need not be done if the target object is in a pack known to be self-contained and connected. If there are multiple packfiles, this optimization can no longer be done. Signed-off-by: Jonathan Tan <jonathantanmy@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
