If you're developing web under modperl + Mason,maybe you should read
the book of 'Practical mod_perl' written by Stas Bekman.Below pieces
are coming from this book:
6.4.10 END Blocks
As the perlmod manpage explains, an END subroutine is executed when the
Perl interpreter exits. In the mod_perl environment, the Perl
interpreter exits only when the child process exits. Usually a single
process serves many requests before it exits, so END blocks cannot be
used if they are expected to do something at the end of each request's
processing.
If there is a need to run some code after a request has been processed,
the $r->register_cleanup( ) function should be used. This function
accepts a reference to a function to be called during the
PerlCleanupHandler phase, which behaves just like the END block in the
normal Perl environment. For example:
$r->register_cleanup(sub { warn "$$ does cleanup\n" });
or:
sub cleanup { warn "$$ does cleanup\n" };
$r->register_cleanup(\&cleanup);
will run the registered code at the end of each request, similar to END
blocks under mod_cgi.
As you already know by now, Apache::Registry handles things
differently. It does execute all END blocks encountered during
compilation of Apache::Registry scripts at the end of each request,
like mod_cgi does. That includes any END blocks defined in the packages
use( )d by the scripts.
If you want something to run only once in the parent process on
shutdown and restart, you can use register_cleanup( ) in startup.pl:
warn "parent pid is $$\n";
Apache->server->register_cleanup(
sub { warn "server cleanup in $$\n" });
This is useful when some server-wide cleanup should be performed when
the server is stopped or restarted.

Subject: [Mason] Catching Apache Child Exit
What is the Mason-native equivalent of an END {} block? That is, how
can I trap the exiting of an apache child, and run my own code just
before it goes away?
Thanks.
