Greetings!
I wanted to add a new subcommand to CVS for the fun of it. For now, let's
assume it's a "cvs ls" command to list the contents of a module/directory. I
was given the attached instructions by KJ Paradise at SourceGear. I followed
them exactly, and
added my command to the 2 lists under lookup_command_attribute to indicate
that it (1) will not require a working directory and (2) will not modify the
repository.
My problem is that it appears to run the subcommand locally, and does not
contact the pserver. So I started looking through diff.c and saw things like
"fire up the server" if we were on the client. Ok, that made sense, but I
have to believe that someone has written down which functions to call when on
the client vs. the server. I'll go snorkeling through the code some more,
but if anyone knows of some good hints somewhere, I would surely appreciate
it! :)
