    fcntl instead of flock

    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...

    fcntl instead of flock

    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...

    Finding size of scalar

    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.

    Finding size of scalar

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

    array ref

    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...

    array ref

    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 =>...

    Network read 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

    Network read timeout

    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...

    Network read timeout

    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...

    square brackets?

    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

    Data Structure Problem

    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...

    Data Structure Problem

    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...

    cpan http_proxy

    cpan http_proxy

    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.

    cpan http_proxy

    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.

    cpan http_proxy

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