in reply to Log4perl log rotation in threadpool environment

Maybe you can:

  1. copy the existing log file to a new name
    e.g. copy log_file to log_file.2012-11-16
  2. truncate the log file
  3. Optionally zip the archive file

That way the file handle for the log file doesn't change.

    Thanks! That was my original idea actually but wasnt aware I could erase (truncate was apparently the word I should have search on) the contents of the file with file handle open. Changed my obnoxious swapping code to 
            copy($currFile, $logDir. $self->{old_logs_name}. '.1') or die 
+"Could not copy the log file because $!";
        my $fh = $self->{fh};
        truncate($fh, 0) or die "Could not truncate the log file becau
+se $!";
        seek($fh, 0, 0) or die "Could not set the position in the log 
+file because $!";
