Hello list-
I think that I have found a bug in Logger::Log4perl::Logger::logdie .
If I use logdie like this:
open(FILE, "/tmp/file.txt") or $logger->logdie("Test");
the following appears in the log:
2002/10/01 09:03:34 FATAL Logger.pm:696 Log::Log4perl::Logger::logdie - Test
Shouldn't the log reflect the line that called $logger->logdie rather than
where the method is located in the Log::Log4perl module?

Hi all,
first of all thanks to Kevin and Mike helping me to solve my
latest problem: change the log output file at runtime. I wrote
a new class, derived form Log::Log4perl::Appender::File and I'm
happy that it works.
Now, my daemon is ready to run. all users using this daemin are able
to configure their loglevel themselves. so I also change the loglevel
at runtime using the functions dec_level() and inc_level().
At the first time, I missed a function for setting the new loglevel
directly. So I wrote the follwing function that does the work for me:
sub set_level ($$) {
my $logger = shift;
my $new_level = shift;
while ($logger->level() != $new_level) {
if ($logger->level() < $new_level) {
$logger->inc_level();
}
else {
$logger->dec_level();
}
}
} #--- set_level
I don't know if there exists a better solution than this. If so, let
me know please.
but incrementing an decrementing loglevel at runtime made my program
run very slow after a short time. I wrote the follwing little program to
test the memory behavior of the above functions:
#!/usr/bin/perl
use strict;
use Log::Log4perl qw(:easy);
use Log::Log4perl qw(:levels);
use Log::Dispatch::Screen;
use Log::Log4perl::Appender;
#-------------------------------------------------------------------
Log::Log4perl->easy_init ($ERROR);
my $logger = get_logger();
while (1) {
$logger->dec_level();
$logger->inc_level();
}
#---------------------------------------------------------------------
I started it and looked at the mem usage of the process. It was increasing
very quickly. Maybe it is a bug, or am I using this functions not correctly
in my test program??
many thanks for your help.
greetings
Reinhold

I have code wrapped within a try catch block.
The logger instead of using the surrounding method/function name use ANON
when printing with the layout [%d][%p] (%C) %M %m%n.
I guess this is because it is the closest control structure to the call.
If this is the case and the stack is:-
package
method_a
try
logger_call
I get logger messages package::anon.
So if I have a number of try statements wrapping my code its hard to see
where the log came from using the pattern layout.
Is there a solution to this?

Log::Log4perl uses the caller() function internally to determine which subroutine it is called from and will dutifully report that it's within an eval(). I think it makes sense for us to get rid of the ANON, I'm gonna put that on my list. However, in your case it will then report "try" as the calling function (and it is the calling function!) -- and I doubt you're gonna like that.

Thanks Mike. file_switch() works fine. Still couldn't get Log::Dispatch::FileRotate working. install Log-Dispatch-FileRotate gave me a 404 and if I just download the cpan module and install it manually it doesn't seem to work. I would be interested to know if anyone has got it working in ActivePerl but for now file_switch does the trick.
