The sample was not quite right. The sub "dave" is a generic sub which calls a procedure with DBD::Oracle. The call to "dave" in the example does fail but what is missing from the example is that the catch also may call "dave" but with a different procedure name. This is closer:
use Try::Tiny;
use Log::Log4perl qw(get_logger :levels);
Log::Log4perl->init_and_watch('/etc/log4.conf', 60);
my $log = get_logger('Q::S');
fred();
sub fred
{
my $x = try {
# dave dies in the cases we get the panic
dave('proc1', {}, 'arg1', 'arg2');
0;
} catch {
my $ev = $_;
if ($sometimes) { # sometimes goes this path and sometimes the
+ else
eval {
dave('proc2', {}, 'arg1', 'arg2');
1;
} or $log->warn("failed $@");
} else {
$log->logwarn("test $_");
}
1;
};
print "$x\n";
return if $x; # <---- this would be q.pl line 1895
}
sub dave
{
# the following line would be DB.pm line 1380
my ($sth, $options, @args) = @_;
}
