From: Jiang Xin <zhiyou.jx@xxxxxxxxxxxxxxx> After successfully connecting to the smart transport by calling process_connect_service() in connect_helper(), run do_take_over() to replace the old vtable with a new one which has methods ready for the smart transport connection. The connect_helper() function is used as the connect method of the vtable in "transport-helper.c", and it is called by transport_connect() in "transport.c" to setup a connection. The only place that we call transport_connect() so far is in "builtin/archive.c". Without running do_take_over(), it may fail to call transport_disconnect() in run_remote_archiver() of "builtin/archive.c". This is because for a stateless connection or a service like "git-upload-pack-archive", the remote helper may receive a SIGPIPE signal and exit early. To have a graceful disconnect method by calling do_take_over() will solve this issue. The subsequent commit will introduce remote archive over a stateless-rpc connection.
