Your biggest problem is to close the pipes to apache from the forked
children, else your clients will see their browser's hang.
Merlyn has a good column on this at www.stonehenge.com column 20.
Here is a simple example to demonstrate the problem.
Make up some long process to test this with, like while(1){sleep(1)}
Then try running it as a cgi script with and without the line which
closes STDOUT, STDIN, and STDERR. With it commented out,
your browser will hang.
##
#!/usr/bin/perl
use warnings;
use strict;
$| = 1; # need either this or to explicitly flush stdout, etc.
# before forking
print Content-type: text/plain\n\n;
print Going to start the fork now\n;
fork exit;
#try running with the following line commented out
close STDOUT;close STDIN;close STDERR;
exec('./fork-long-process-test-process') || warn funniness $!;
#if you use system here, instead of exec, the parent process
#hangs around for child to exit, even though the cgi exits.

RE: pop-up window with database access
Avoid Javascript is a pretty far-reaching statement. If you want to launch
a popup window, Perl isn't going to do that, Javascript is. It only takes
one or two lines of client-side code. There are easy-to-follow Javascript
primers at
http://javascript.internet.com and
http://www.htmlgoodies.com/primers/jsp/jsp_toc.html
With regard to the database functionality, Perl and MySQL are powerful tools
if you have the time and inclination to learn them.
Good reading: 'Learning Perl', 'Perl in a Nutshell', 'CGI Programming with
Perl' and 'Programming the Perl DBI' (all O'Reilly books). There is also an
O'Reilly MySQL book but I forget the name of it. Actually the documentation
that comes with the MySQL distribution is quite good.
http://www.mysql.com/doc/en/index.html
I also like the SAMS series of SQL books ('Teach Yourself SQL in ...').
This is really a time and learning curve issue. If you don't have much time,
maybe an off-the-shelf CGI is the answer. But I think you'll probably get
more benefit in the long run if you go through the steps of building it
yourself.

Has Perl extra memory!?
Hi everybody!
One of my program generates a HTML formulary whose number of checkboxes fluctuates
(they are named mod_0, mod_1, mod_2, mod_3...etc).
Therefore I need a loop in my other program which has to read the formulary :
my $count ;
for ($count=0; $count = $num; $count++)
{
my $mod = $cgi-param(mod_.$count) ? $cgi-param(mod_.$count) : ;
if ($mod ne )
.etc
($num is the number (-1) of checkboxes and it is stocked in a hidden inputin the Web
page)
Unfortunately it seems that Perl memorises the values of these $mod_i and doesn't
always execute the script with the values that are given to it!!
I have tried differents ways of declaring these parameters (our, my, local, outside or
inside the loop...etc) and there has always been the same problem.
Basically the first formulary you fill is well executed, and after that there is no
way to tell when it'll start to bug! Sometimes it executes the formulary you have
filled three or four times before!
I hope someone could help me with this, this problem is poisoning my programs!

Re: Has Perl extra memory!?
Sounds like a mod_perl problem. If you are using Apache::Registry apache
will compile your script once and just keep running it until the child
process dies. This means that any global variables you pass to it will stay
in scope.
How is your script being called?

RE: pop-up window with database access
Define a lot of people. I use Pop-Up Stopper myself, but when there is a popup window that I *want* to see, I can CTRL-click the link. I don't have to turn Javascript off. Most browsers are preconfigured to allow Javascript and the user or the company has to explicitly turn it off. I agree that it's probably going to cover more ground if he keeps the user experience within the main browser window. 95% of the clients I deal with still have Javascript enabled. But 100% of them can see what's going on in their browser, so you have a point. I guess it depends how important the pop-up function is to the project. Perl and MySQL are quite capable of handling the back end, but they're not going to manage this function.
