| Subject: | problems with JUNOS::Access signal handling |
hello,
I'm building a new open-source software for backbone topology
discovery, and I utilize your JUNOS Perl package available at CPAN.
JUNOS::Access module, line 315, redefines the signal handlers for the
parent process:
# If something bad happens kill this process off...
$SIG{INT} = $SIG{__DIE__} = $SIG{HUP} = $SIG{TERM} =
sub { kill 9, $pid; exit };
This is a bad practice, and it imposes difficulties in
troubleshooting: when something goes wrong, the process exits before
it even has a chance to print the error message -- for example, in
case of Perl errors. In my case, that was referring to an object from
undefined value.
Besides, signal handling is definitely not a job of a library module.
The calling program should take care of the signals itself.
Please remove these lines from the code and update the CPAN repository.
If you're interested, I will let you know about the project as soon as
it's published at SF.net.
thanks,
stanislav
