[log4perl-devel] utf8 and differences between Log::Log4perl::Appender::File and Log::Dispatch::File

[Martin J. E. <mar...@ea...>]

Hi,

I am using Log::Log4perl 1.06 in a rather large project and getting the old
"Wide character in print..." problem. Most of my appenders are file appenders
and I also have a Log::Dispatch::Screen handler. All my handlers have:

log4perl.appender.APPENDER.utf8 = 1

set and I've set binmode ":utf8" on STDOUT and STDERR and yet I'm still getting:

Wide character in print at /usr/lib/perl5/site_perl/5.8.8/Log/Dispatch/File.pm
line 124.

After loads of searching around and debugging I realised I'd missed the obvious
which is I am using two sorts of appenders - Log::Dispatch::File and
Log::Log4perl::Appender::File. The latter seems to support the utf8 flag, the
former does not. I have no idea why I've mixed File appenders from different
places. Other than the obvious difference of one supports utf8 and the other
does not is there any reason any one knows why I shouldn't just swap my
Log::Dispatch::File appenders to Log4perl ones?

As an aside, why the duplication of File appenders with different
functionality? This cost me some time to locate.

Thanks.

Martin

I'd recommend using Log::Log4perl::Appender::File instead of
Log::Dispatch::File throughout your project. The former has a lot of
options (utf8, re-creating missing files, switching files,
permissions, umasks ...) that the latter doesn't.

Log::Log4perl::Appender::File is part of the Log4perl project,
Log::Dispatch::File is not. It's 3rd party.

Log4perl supports appenders in the Log::Dispatch::* hierarchy to
avoid duplication of effort, which backfires in this case :).

As a rule of thumb, if there's a Log4perl appender and a 3rd party
appender that are doing the same thing, use the Log4perl one --
chances are they've been created because the 3rd party appender
wouldn't provide the functionality needed.
