A developer creates an application by writing CFCs that comprise the model section and CFM templates that comprise the views He then writes CFCs that extend the framework s core controller CFC to provide interaction between the two When an event is requested, any number of controller methods are fired that access data in the application or session scopes, the database, or from other data sources Events also include views to render the final output to the browser For more detail on how this all works, see the Model-Glue Fundamentals article in 27 of this collection The other guiding design principle behind Model-Glue is the concept of implicit invocation (II) This means that if the getProductsList message is broadcast, for example, all controller methods configured in the Model-Glue config files <controller> section listening for the getProductsList method will fire.

Both handlers may customize the error or warning before passing it on to a real warn or die (the action of the handler is suppressed within the handler itself, so calling warn or die a second time will do the real thing). A warning handler may choose to suppress the warning entirely; die handlers, however, cannot avert death, but only do a few things on its deathbed, so to speak. See 16 for more on die and warn, and registering handlers for them. The hook mechanism is not extensible; the __ prefix and suffix merely distinguish these special handlers from true signal handlers. They do not, however, allow us to create arbitrary signals and handlers.

Signal handlers are just subroutines. When they are called, Perl passes them a single parameter: the name of the signal. For example, here is a program containing a very simple signal handler that raises a warning whenever it receives an INT signal, but otherwise does nothing with it: #!/usr/bin/perl # inthandler1.pl use warnings; use strict; sub handler { my $sig = shift; print "Caught SIG$sig! \n"; } # register handler for SIGINT $SIG{INT} = \&handler; # kill time while (1) { sleep 1; } Note that since the handler handled the exception, the program does not exit. If we still want the handler to exit after performing whatever other actions we need done, we must add the exit command to the end of our handler. Here is another handler that implements this scheme, using a private counter. It will catch the first two signals but defer to the normal behavior on the third reception: #!/usr/bin/perl # inthandler2.pl use warnings; use strict; { # define counter as closure variable my $interrupted = 0; sub handler { foreach ($interrupted) { $_ == 0 and warn("Once..."), $interrupted++, last; $_ == 1 and warn("Twice..."), $interrupted++, last; $_ == 2 and die ("Thrice!"); } } } # register handler for SIGINT $SIG{INT} = \&handler;

# kill time while (1) { sleep 1; } A few platforms (BSD systems, typically) cancel signal handlers once they have been called. If we want these systems to be maximally portable, we have to reinstall the handler before we exit it, if we wish it to be called again: handler { $sig = shift; # reinstate handler $SIG{$sig} = \&handler; ... do stuff ... } To prevent another signal from coming in before we have redefined it, we will do that first in every handler. Since this does no harm even on platforms that do not need it, it is a good piece of defensive programming if we are worried about portability.

To put it in more tangible terms, if clean the kitchen is a message broadcast by the momisTired event, then any subtasks (such as sweep the floor and load the dishwasher) registered under the KidController will fire Implicit invocation abstracts a larger task, such as productslist, into smaller tasks, such as get products query and render products list page, by making it the listener s responsibility to respond instead of the broadcaster s responsibility to delegate explicitly..

The preceding handlers are good examples of signal handlers in the sense that they do very little. Signals implicitly herald a critical event, so executing complex code, and especially anything that causes Perl to allocate more memory to store a value, is a bad idea.

For example, the following signal counting handler is not a good idea; it allocates a new key and value for the hash each time a signal it has not seen previously arrives. %sigcount; sub allocatinghandler { $sigcount {$_[0]}++; } This modified version is fine though, as we have guaranteed that all the keys and all the values of the hash already exist, so no new memory needs to be allocated within the handler: %sigcount = map { $_ => 0 } keys %SIG; sub nonallocatinghandler { $sigcount{$_[0]}++; } The rule of thumb for any signal handler is to do the absolute minimum necessary.
