Use of uninitialized value in string eq at Sys/Syslog.pm line 631.

Hi. This is imacat from Taiwan. I have just upgraded to Sys:Syslog 0.18, and got flooded with errors from my cron scripts that use Sys::Syslog. They all says: Use of uninitialized value in string eq at /usr/lib/perl5/5.8.8/i686-linux-thread-multi-64int-ld/Sys/Syslog.pm line 631. After some tests, I found that if the script openlog() and closelog() without any logging, $current_proto will be undef and hence caused this. The demostrative terminal log is below. imacat@leaf ~ % cat /tmp/sys-syslog-test #! /usr/bin/perl -w use Sys::Syslog; openlog("sys-syslog-test", "", LOG_USER); closelog(); imacat@leaf ~ % /tmp/sys-syslog-test Use of uninitialized value in string eq at /usr/lib/perl5/5.8.8/i686-linux-thread-multi-64int-ld/Sys/Syslog.pm line 631. imacat@leaf ~ % I have attached a simple patch. Hope that this helps. Please tell me if I can be of any help, or if there is any question. Thank you.

Thanks, applied. I've also commited your example as a regression test with Test::NoWarnings. Thank you for reporting this problem in such a clear and documented way :-) -- Sébastien Aperghis-Tramoni Close the world, txEn eht nepO.

This "bug" seems very common, and therefore I request a new release of your popular module.

I understand that, but the new version is not fully finished as Win32 support still doesn't perfectly work and I'd like to see it working. There are also some issues on OSX that I must check if there are still present or not. -- Sébastien Aperghis-Tramoni Close the world, txEn eht nepO.
