Hi All,
I am trying to see the rsync source code. I could see that there are main
three processes: I realize that Server or Client becomes Sender or Receiver
based on arguments provided.
1. Daemon
start_daemon : clientserver.c
2. Server
if(sender) {
call recv_filter_list : exclude.c
call send_file_list : flist.c
call send_files : sender.c
} else {
call recv_filter_list : exlude.c
call recv_file_list : flist.c
call do_recv : main.c
call recv_files : receiver.c
call generate files : generator.c
}
3. Client
call do_cmd : main.c
call client_run : main.c
if(sender) {
call send_filter_list : exclude.c
call send_file_list : flist.c
call send_files : sender.c
} else {
call send_filter_list : exclude.c
call recv_file_list : flist.c
call do_recv : main.c
call recv_files : receiver.c call generate files :
generator.c
}
I have noticed that deamon process will start only if am_daemon argument
provided. My questions are
1. What is the roll of deamon process. How it different from server? Does it
run always on remote machine? When I do rsync from client how remote
deamon/server will get triggered?
2 .Where the arguments are being set. I cannot see any of arguments(like
am_server, am_deamon etc) is being set anywhere.
Please help me on this so that I can proceed.
Thanks,
Jignesh
