A strategy I have used that has worked well is to have the application
keep track of the timestamp on its executable file. When the time stamp
I do the check before handling each request. It might be better to do
it after the request, but that might cause problems being sure you are
running the latest version in a compile and test cycle.
Then to roll out a new version I do:
mv prog prog.old; mv prog.new prog
The first method has the advantage of being able to undo the change if
it goes horribly wrong.
This works as well:
rm prog; mv prog.new prog
This works because Linux maintains a link to the file as long as it is
executing. The disk space is not recovered until exit.
This also works beautifully in a gcc compile and test cycle because gcc
removes the old one before creating the new one.
