I think you're going with an assumption here that the client libraries
for 64bit Oracle must be 64bit, too. Not true. I don't know if Oracle
is shipping 64bit client libraries yet, but they are certainly still
shipping 32bit client libraries.

I think 32bit Perl is what you want.

Hi,
I am writing a simple proxy and have hit a problem with forking.
Basically my proxy sits between the browser and the real-proxy (that
servers my department) parsing HTML.
I open a server socket and use the normal while loop to deal with
clients:
while ($browser = $server->accept()) {
If I then fork (the line I use is next if $pid = fork;) and allow to
child to open a new socket to the real-proxy I get an error when I try
to write.
If though I the parent to open the connection to the proxy BEFORE I fork
every thing works fine!
Can some one tell me why please?!?!?!?!
And if/how I can get the child to open the socket to the real proxy?
Thanks in advance,
Tim

Message-Id: <39904A68.F542DA41@shentel.net>
Let's say you have the following in your html form:
<input type=checkbox name=choice1 value=on>
Use the following perl do write to your database if the checkbox is not checked.
$Choice1 = param('choice1');
if($Choice1 ne "on")
{
put your database action here........
}
What happens is that an unchecked checkbox will upload absolutely nothing to the
server, in other words it is ignored by the browser. If you use the above code
in Perl you will be writing a value to the database even though the form sent
nothing regarding the checkbox to the server because you have declared the
variable for the checkbox and it will contain nothing unless the web page has it
checked whereupon it will upload the value if "on" as in this example.

That is not the proper way to pass by reference using Perl 5.
function(\%hash1, \%hash2, $string1);

Not by using a typeglob, but certainly by using a proper reference, as

Subject: Re: CGI.pm not passing ampersands properly
Message-Id: <39904F92.5EFB3D2@shentel.net>
If you are depending on the info from a text box in an html form you might use
a little javascript error checking in your page to convert characters like the
ampersand to %26 before it gets posted and then decode it with your perl script
once the server receives it. This will prevent accidental parsing of your data
by your script at the '&' position in the text data.
Just a thought.

I have a similar problem,
I need to pass data from one cgi-script to another, but I don't know how to
transform the data to the specific CGI format, so under some browsers
(Netscape for example), the data is not readable.
I need to make a function in perl that preprocess the text data, but I do
not know how to do it.
I would thank anyone that could send me any help.

You would be very surprised but they do. Point is used only when you
deal with computers. If they write anything on paper in most european

Most calculators use point, yeah, but the phrase "...mathematicians

Yes. I find myself standing in the middle of discussion
of Perl programming, computers and mathematics. I am
hard pressed to find a relationship between cultural
aspects of comma usage and a decimal point for CPU
processing. Duh?
This discussion of cultural inflections is nothing
more than boys whom suffer terminal testosterone
poisoning looking to play weenie wagging one-upmanship
and, in reality, are grasping at inane straws hoping
to pull out a long one.
I'll stick with the Scarecrow. Now that boy has got some

Generally, CPU's and math co-processors don't use decimal points
at all; instead, they store "floating point" numbers in a
mantissa/exponent format in which the mantissa is always
normalized the same way, so that there is no need to store the
decimal point[1] because it falls in the same place every time.
In other words, on most computers, floating point numbers neither
actually have points, and if they did, their positions would be fixed.

[1] Also, there is not decimal point since
it's all happening in binary anyway.

So, enter this simple addition into your computer, favorite
calculator or my preference, a sliderule, without decimal points,
2.2 + 2.2
otherwords, without decimal points,
22 + 22
and tell me what you get for a sum.
You boys will be exceptionally challenged to substantiate
your claims decimal points are not needed in mathematics.
Use commas all you want. Use floating point all you want.
I will continue to be realistic and use decimal points.

Although it might not be totally impossible still I highly doubt that there
is any CPU or math co-processor that has any notion of what you call a
decimal point.
You may want to brush up on how numerical computation is done in a computer.

The vast majority of countries in particular in Europe uses a decimal comma
instead of a decimal point. Japan (and some other FE countries) follow the
US, there you are right.

Maybe it's that the US follows Britain. But I would say that,
wouldn't I.
Pity they can't get a sensible date format, though.

Duh. :-)
Locales are all about the relationshop between the local cultural
aspects of comma usage (and other things like dates and currency) and
how the computer represents the data internally. Internally, IEEE
floating point numbers don't have ANY decimal points. Locales allow a
programmer in the US to write
$pi = 3.14159
and a programmer in France to write
$pi = 3,14159
Both numbers will be stored internally exactly the same way.

Subject: CPAN shell use in alternate perl directory
Message-Id: <878zu7ioxq.fsf@quicksilver.pacbell.net>
Hi folks,
Here's the situation I'm in:
I'm installing perl 5.6.0 for distribution on a bunch of systems.
I've followed the instructions in the INSTALL file which point to
-Dinstallprefix and -Dprefix, and then modifications of
$archlib/Config.pm and $archlib/.packlist. That's all good.
I now have a tree in /tmp/perl5 which is ready for tarring. But
before I do, I'd like to install to it a large set of modules using
the CPAN shell. (perl -MCPAN -e shell)
I'm choosin the CPAN shell approach because there will be a large
amount of dependencies, and it's just really handy.
Is there a good way I can tell the shell to look in the /tmp/perl5
tree for installed modules, and do all installing there as well?
I've tried: /tmp/perl5/bin/perl -MCPAN -e shell
but then it complains it can't find CPAN.pm because it's already
looking in -Dprefix. (Which is sensible, just problematic in this
situation.)
Has anyone tackled this sort of situation before?
Thanks in advance for any responses.

two problems:
1. last_insert_id() doesn't use a "from" clause.
2. you're doing too much work. :)
these two lines will replace the 5 you have above...
@row_ary=$dbh->selectrow_array('SELECT LAST_INSERT_ID()');
print "created new row with id $row_ary[0]\n";
oh, and you have one other choice. for sufficiently modern versions of
mySQL/DBI/DBD::mysql, you can do this:
my $sth=$dbh->prepare('INSERT INTO test (label) VALUES (?)');
$sth->execute('new label');
print "created new row with id $sth->{'insertid'} \n";
the key here is that the statement handle automatically has the
insertid element created.

it is a well known problem that we are addressing in perl6. but the best
solution is not to change the global $/ around. better to use something like:
sub read_with_sep {
my ( $fh ) = @_ ;
local($/) = $my_rec_sep ;
return <$fh> ;
}
then the old value will automatically come back when you exit this sub.
you can also do that inline inside a code block.

Subject: Differing parses under 5.005, 5.6?
Message-Id: <39906211$0$48168$44a10c7e@news.net-link.net>
The following code worked _just fine_ under 5.00503. Under 5.6, however,
perl complains about
Variable "$userdata" is not imported at testvars.pl line 7.
Global symbol "$userdata" requires explicit package name at testvars.pl
line 7.
use strict;
use vars qw(%userdata %_pages @sortlist @showlist);
sub showfolder_count_unshown_items {
return 0 if $userdata{show0};
@showlist = grep((
$userdata{show0}
or /^f/
or !defined($_pages{$_})
or &refisnew($_pages{$_})
or ($_pages{$_}->{status} ne 'VALID')
or ($_pages{$_}->{score} > 0)
), @sortlist);
scalar(@sortlist) - scalar(@showlist);
}
Now, the odd thing here is that if you take line 7 and move it,
@showlist = grep((
/^f/
or !defined($_pages{$_})
or &refisnew($_pages{$_})
or ($_pages{$_}->{status} ne 'VALID')
or ($_pages{$_}->{score} > 0)
or $userdata{show0}
), @sortlist);
then it parses just fine. (By the way, I realize that the logic in this
code is probably wrong, and since $userdata{show0} doesn't change within
the grep-loop, it really doesn't need to be re-evaluated for each trip.
That's not the issue. The code worked, and we were reluctant to change
it. Then 5.6 breaks it, and now we will rewrite it anyway.)
Is this a 5.6 bug?

Subject: execute perl script without saying perl filename.pl
Message-Id: <8mpprb$bk6$1@peabody.colorado.edu>
Hi,
On Windows NT at the dos prompt you can just type in your perl script and it
executes but on Win98 I have to type in
perl filename.pl for my script to run. Is there a way on Win98 to make it
run the perl script without having to type perl in front of it at a dos
window.
Really want I'm wanting to do is set up a webserver on my Win98 box to able
to execute perl cgi programs.
Thank you for your help.

AFAIK, you don't need that functionality. Just configure your web server
correctly. That is my experience with Apache and O'reilly's WebSite.

Use one of these:
chmod +x script_name.pl
chmod 755 script_name.pl
This will render your script executable, and you can run it like this:
script_name.pl (rather than 'perl script_name.pl')
good luck!

Actually, it renders an error. The poster clearly specified he

Well, you should be able to hide it just about as well as you can hide
it for code in just about any other language.
"All" you have to do is embed the perl interpreter in a C program which
decrypts input files when loading them, using a key that's built into
the executable of the program. You could probably even just modify the
regular perl exectuable's source rather than writing your own C program
that does this.

All it takes is for one customer to illegally copy the source code for
