Re: [log4perl-devel] log4perl multithread question

[Judd T. <ju...@or...>]

Ok, I've got the basic version of Log4perl::Appender::Synchronized
running, but I'm running into a problem where the IPC::Shareable
semaphores are created without group permissions. 

This causes apps starting with a different user to crash, as they don't
have the correct permissions to be messing with those semaphores.

Looking at the Synchronized.pm file, it shows an arg to new(), %options,
that is passed to IPC::Shareable tie() call. That would be an ideal
place to stick on the Mode => '775' option.

How can I define options to the constructor, if it's only init'd with a
call to read a config file (i.e. how can I pass the options through the
config file)?

Thanks,
	Judd
