[log4perl-devel] PerlEx Precompiler -1 Error with Log4perl

[Maxim M. <mal...@ya...>]

Hi everyone:
I'm using Log4perl (v 0.34) quite extensively in my
modules and it works just great on my Win2K machine
with Perl 5.6.0 and 5.8.0. I installed it using PPD
from this site. I have recently installed my script on
the IIS 5.0 with PerlEx.dll for the Active State Perl
5.6.0 build 633 and have intermittent problems with
Log4perl being unable to precompile whenever I change
the script. I'm using Log::Dispatch::File as my
Appender and the error seems to be related to it:

Precompiler: Eval Error: 

Package:[PerlEx::Precompiler::c_::wwwroot::archive::cgi_2dbin::survey_asp]
	File:[C:\wwwroot\archive\cgi-bin\survey.asp]
	Error:[Can't call method "log" on an undefined value
at c:/Perl/site/lib/Log/Log4perl/Appender.pm line 177.
]
Precompiler: Returning -1 at 
594

My config file works fine with the regular Perl:
=======================================================
log4perl.logger = INFO, Logfile

# appender
log4perl.appender.Logfile = Log::Dispatch::File
log4perl.appender.Logfile.filename = logs/bdb.log
log4perl.appender.Logfile.layout =
Log::Log4perl::Layout::PatternLayout
log4perl.appender.Logfile.layout.ConversionPattern =
%d %X{IP} %p %F{1}:%L (%M) => %m%n
=======================================================
The module where Log4perl is called is inside the
BEGIN block and it looks like like the Appender's new
method fails to create an object correctly. If I
restart IIS, the error goes away but I feel
uncomfortable to use the script in production without
knowing what's causing the problem. Are there any
patches I need to apply to use Log4perl with PerlEx?

Any help is greatly appreciated.
Thanks,

I'm not using PerlEx, so I can't help you there, but one thing I wanted
to check: There's been a recent change to Log::Log4perl in that it ships
with its own appenders (Log::Log4perl::Appender::File etc.) and not with
Log::Dispatch by default. Could it be that you haven't installed
Log::Dispatch but are using it in the conf file and that PerlEx throws
a cryptic error messages because of that?

Hi Mike:
Log::Dispatch is installed and I tried switching to
using Log::Log4perl::Appender::File. I got the same
error on the same line. It looks like PerlEx doesn't
pull in appenders properly.
Thanks,
Maxim

Interesting ... the appenders are pulled in by Log::Log4perl via

    eval "require Foo"

at runtime -- maybe that's a problem for PerlEx?

Not having worked with PerlEx either I'm going out on a limb here, but 
from reading the documentation I think it has to do with the way PerlEx 
persists across invocations and the way Log4perl loads modules 
dynamically using 'eval'.  If you change your script without restarting 
IIS maybe PerlEx reloads *part* of Log4perl's data structures as it 
recompiles your script.  Restarting IIS gives you a clean slate. That's 
my guess.

Do you ever see the error when you *don't* change your script?

Hi Kevin:
No, I don't recall it happened, if I didn't change the
script. Perhaps, you are right. I'll post the question
to the Active State PerlEx Mailing list.
Thank you,
Maxim
