Can't call method "ping"

RT Users

Hi, this morning, I started getting this message in /var/log/messages:

[Thu Aug 21 08:36:08 2003] [error] Can’t call method “ping” on an
undefined value at /opt/rt3/lib/RT.pm line 122.

This seems to coincide with sporadic ‘Internal Server Error 500’ messages
in the Web GUI.

The specific portion of the file is:

sub Init {
require RT::Handle;
#Get a database connection
unless ($Handle && $Handle->dbh->ping) {
$Handle = RT::Handle->new();
}
$Handle->Connect();

mysqld is running and seems to be ok. I can add, comment, and resolve
tickets, but periodically, I get the Error 500 message.

Any idea what the cause of this is?

Thanks.

Fixed in RT 3.0.5pre3 or so. We had to do extra checking for the mysql
“morning bug” even though DBD::Mysql and Apache::DBI both purport to
magically fix it.On Thu, Aug 21, 2003 at 11:16:16AM -0700, amelton@gservices-us.com wrote:

Same thing has happened here recently with MySQL 4.1.

sub Init {
require RT::Handle;
#Get a database connection
unless ($Handle && $Handle->dbh->ping) {

Changing this line to

      unless ($Handle && $Handle->dbh && $Handle->dbh->ping) {

seemed to fix the problem with no apparent drawbacks.

Thanks,

I just encountered this bug in that RT 3.0.5pre3 with MySQL 4.0.14. It was oddly manifesting as the style sheet only generating the error. Autrijus's fix did the trick.
