Dear Monks:

Under FastCGI processes, is there a good way to update a preloaded Perl Module just like Apache::Reload for mod_perl users. I am currently using kill -9 to restart the fcgi process, so each time I get some changes on my modules, I have to restart(kill) fcgi process to update these changes.. Is there any better way to do this?? I am using Apache2.0.59, mod_fastcgi/2.4.2, CGI::Fast with HTML::Mason.

A couple of days ago, I asked this question in FCGI's mailing group, some suggestions include:

  1. Add code that checks module timestamps when you get a call and does a do on the changed files before processing.
  2. Add a signal handler that processes the files when it is received

For suggestion-(1), I think I can do things like 

    if ( -M "/path/to/lib/MyModule.pm" < 0 ) {
        require MyModule;
        MyModule->import(qw[ :mytag ]);
    }

But my questions keep:

  1. the '-M' test looks expensive if I put it in the FCGI loop and do it on every request
  2. what are the differences between 'require' and the suggested "do" here?, given that I do need to import some functions from that modules
  3. What should be considered differently between an OO-modules and non-OO-modules in this context..

For the suggestion-(2), I am not sure which SIG should I trap to handle the file change

Thanks for your further advices..

Best regrads,
