rsync - Jun 2009 - Which function in generator trigger the file transfer?

Dear List,

I checked the function "generate_files", which might be simply stand
for
generator, but didn't find where triggers the file transfer. As receiver
will use "read_ndx_and_attrs" to read iflags to judge if it's need
to be
transfered? 

If I'm wrong, please correct me. Can anyone help to point it out?
Thanks.

I'm new to rsync, just read little of codes right now. 

I have read the pipe line would be "generator ? sender ? receiver". 
But I didn't find where rsync makes sure that the file is going to be
transfered (time stamp/file checksum).

     A. Is there anyone familiar with the code,  can give me some tips
        on 
a) where generator send the time stamp/file checksum 
b) where sender compared time stamp/file stamp
c) where receiver make sure that it's a go mission?

I think some function names is enough for me shorten the time and get a
basic understanding of the code.


Thanks in advance.

You can get a good overview of how rsync works here:

    http://rsync.samba.org/how-rsync-works.html

After reading through that, you should discover that it's the generator
that decides what work gets done.
