Re: Initialize object permanently
Thanks for the reply, it's a dynamic server side script that currently using
CGI, but I am going for mod_perl. The interface is something like Google, so
everytime the user make a request to lookup let's say the meaning of a word,
the WordNet object have to be initialized. Is there a work around of this with
mod_perl ? Thanks

When you say 'web application', do you mean a server-side CGI script or a
client-side program that interrogates the Web and also needs access to the
dictionary?

Initialize object permanently
Hello, I am using Wordnet::QueryData which allow access to a very huge
dictionary data. The initialization of object
my $wn = WordNet::QueryData->new;
took
2 wallclock secs ( 2.36 usr + 0.07 sys = 2.43 CPU)
Then the subsequent request for the data is exetremely fast

Fw: Perl maximum execution time
Thanks for the reply, but sometimes I don't know where is the code that cause
the infinite loop. Is there such as thing as perl configuration file, to set
the execution time for any code, any where in the program just like php.ini
file. Thanks.

You can set an signal to go off after X seconds with the alarm* function:
#!/usr/bin/perl
use strict;
use warnings;
my $timeout = 5*60; #timeout after five minutes
eval {
local $SIG{ALRM} = sub { die "timeout\n" };
alarm $timeout;
#stuff you want to run in under five minutes
};
die unless $@ eq "timeout\n" if $@;

Perl Serialize object as string
Hello everyone, I need to serialize an perl object to STRING TEXT, not scalar or file. The Storable module allow serialization to file and scalar variable, but this is not possible for passing between the perl and prolog program, that's why I need it to be string.
