Thanks for your response Trojan. From the sendmail release notes for v8.13: "The Linux kernel version 2.4 series has a broken flock() so change to using fcntl() locking until they can fix it. Be sure to update other sendmail related programs to match locking techniques" This script scans...

Hi All, I've got a problem with a script running on a Linux 2.4 kernel where 'flock' is apparently broken. Therefore I'm thinking of using the 'fcntl' wrapper. Here's the existing flock call: $retval = flock(QF, $LOCK_EX|$LOCK_NB) So, I need to create an exclusive lock on an entire file...

Thanks ishnid. That only works with scalars. Need to be able to size arrays (I guess I could cycle through) and other non-scalar entities.

Thansk stevexff. What if I had some binary or object data? How could I determine the size (in bytes) used in memory?

Hi All, How do I find the size (in bytes) of a scalar? Specifically, I want to find the size of a string (including control chars etc) in memory. Thanks, rotis23

Yeah, thanks Ishnid. I've just spent most of the afternoon on http://perl.plover.com and I've got very little coding done!!!

sorry - "doesn't work" means that $smtp is undefined i.e. there was an error within the SMTP module. ishnid - square brackets do work. Why? fishiface - @SMTPServerList is declared in main as: $SMTPServerList[0] = '127.0.0.1'; $SMTPServerList[1] = '127.0.0.2'; Thanks for your help people...

Hi All, Got a problem using a reference to a main array within a package. Why does this not work: my $smtp = Net::SMTP->new(\@main::SMTPServerList, Timeout => $main::SMTPServerTimeout); and this work: my @templist = @main::SMTPServerList; my $smtp = Net::SMTP->new(\@templist, Timeout =>...

Looks like alarm is the way to go with DBI: http://search.cpan.org/~timb/DBI-1.48/DBI.pm#Signal_Handling_and_Canceling_Operations

I would rather make the client tolerable of this problem that apply fixes to the firewall or server. This way the client can tolerate network outages and other failures that ungracefully terminate the connection. Apparently I can use SO_KEEPALIVE socket option to maintain a heartbeat within the...

Hi All, I have a process that is having it's (MySQL DBI and Net::LDAP) connections terminated by a firewall after a period of inactivity. The problem is that the process (client) doesn't know this and attempts to read (well, actually the ldaps earch function and the mysql do function) from a...

Thought as much - cheers!

If you're just trying to pull out urls, try HTML::LinkExtor.

Hi All, What's the difference between declaring an array using square or normal brackets? Does it create a reference if they're square? Thanks, rotis23

What I really need to do is to grab a value from the data structure based on another value. e.g.: Get MORE_DATA from the data structure where VALUE = 10. I know I can do this using an array and it's index, but the values aren't sequential from 0. I guess the other alternative is to search...

Hi All, Wonder if you can help me because I'm getting bogged down with this. I have an application written in Perl that includes several modules and they all reference a Constants.pm module for obvious reasons. Now, I have some constants that are more complex than just a number and I've been...

;)

apparently you have to use commit to make the 'o conf' change to the config.pm (or just hack the config.pm). Thanks for your help Mike.

Thanks Mike. That works but the config isn't stored. If I exit and and then go back into cpan the old settings are restored.

OK - figure out how to rebuild config: o conf init How do you specify none/nothing when it asks for a http_proxy?
