Here is my file (referred to below as /home/msouth/disconnect.pl): 
#!perl -w
use strict;
use DBI;

my $dbh = DBI->connect('dbi:mysql:database=msouth_reg_db;host=redacted
+.example.com', 'user', 'pass');
my $rc = $dbh->disconnect;
warn "dbh->disconnect returned [$rc]\n";
if (my $ping_val = $dbh->ping) {
    warn 'here is the thread id ['. $dbh->{mysql_thread_id} ."]\n";
    warn "ping returned [$ping_val]\n";
    warn "here are Apache-matching keys \%INC:". join "\n", grep {/Apa
+che/} keys %INC;
}
else {
    warn "ping returned [$ping_val]";
}

if i run this from the command line, it prints what I expect: 
dbh->disconnect returned [1]
ping returned [] at /home/msouth/disconnect.pl line 14.

If it runs via a "PerlRequire" in my apache conf: 
ErrorLog       /home/msouth/local/apache/logs/error.log

LockFile       /home/msouth/local/apache/logs/httpd.lock
PidFile        /home/msouth/local/apache/logs/httpd.pid

# Mod-perl
<IfModule mod_perl.c>
    PerlRequire /home/msouth/disconnect.pl
</IfModule>

Port   8106

the output upon starting apache is as follows: 
dbh->disconnect returned [1]
here is the thread id [774516]
ping returned [1]
here are Apache-matching keys %INC: at /home/msouth/disconnect.pl line
+ 11.

(new edit with additional information)

I found that, when the disconnect() fails, I can see from mysql's "show processlist" that that the thread with that id is indeed still connected. In my application, I need the threads to disconnect so they will not use resources on the server.



Perl version is 5.8.3, Apache 1.3.33, mod_perl 1.29

Also, I apparently posted this here after not waiting long enough on #perl. Sorry about that.

In reply to disconnect, then ping returns true under apache, false from command line, no Apache::DBI around. Why would this be? by msouth
