[log4perl-devel] Log::Dispatch::FileRotate not working with "append" mode?

[<wzh...@gm...>]

Hi there,
Here is my log4perl.properties file:
#predefined variables
layout_class   = Log::Log4perl::Layout::PatternLayout
layout_pattern = %d %5p %F{1} %L> %m %n
layout_email_pattern = %d{yyyy-MM-dd HH:mm:ss} [%F{1}:%c{1}:%L] %5p> %m%n
log_file_appender = Log::Dispatch::FileRotate

#log4perl category
log4perl.logger.main = WARN, MainLogfile, Email

log4perl.appender.MainLogfile = Log::Dispatch::FileRotate
log4perl.appender.MainLogfile.filename = main.log
log4perl.appender.MainLogfile.mode = append
log4perl.appender.MainLogfile.max         = 5
log4perl.appender.MainLogfile.DatePattern = yyyy-MM-dd
log4perl.appender.MainLogfile.TZ           = PST
log4perl.appender.MainLogfile.layout = ${layout_class}
log4perl.appender.MainLogfile.layout.ConversionPattern = ${layout_pattern}

I'd like the main.log to rotate at midnight, and persist among restarts (log
file not wiped out among restarts) so I used "append" mode here, but the
rotation is not working, did I set this up wrong?
Thanks in advance!

David

Can you specify what exactly isn't working?

Note that the rotation will only happen if you're writing a message.

Also, if you're not sure if it's working correctly, use a shorter
rotation interval (e.g. every minute) to create a test case you can
verify quickly.

I have a script running, which can be stopped and restarted frequently. I
was able to get the file rotation working until I added
"log4perl.appender.RunMonitorLogFile.mode = append" to set the mode to
append, so the previous script run's log file doesn't get wiped out after a
restart of the script. It's not rotating anymore. What I want is: continuous
logging, and log rotation at midnight.Thanks for your help!

Works for me.

Here's a script for you to verify, call it a couple of times, then wait
a minute, and call it again, and you'll see that it'll create
test.log.1, test.log.2 etc.

     use strict;
     use Log::Log4perl qw(get_logger);

     my $conf = q(
     log4perl.category.Bar.Twix         = WARN, Logfile
     log4perl.appender.Logfile          = Log::Dispatch::FileRotate
     log4perl.appender.Logfile.filename = test.log
     log4perl.appender.Logfile.mode     = append
     log4perl.appender.Logfile.DatePattern = yyyy-MM-dd-HH-MM
     log4perl.appender.Logfile.max = 5

     log4perl.appender.Logfile.layout = \
     Log::Log4perl::Layout::PatternLayout
     log4perl.appender.Logfile.layout.ConversionPattern = %d %m %n
     );

     Log::Log4perl::init(\$conf);

     my $logger = get_logger("Bar::Twix");
     $logger->error("Blah");

Try it out!
