    NAME

    DBD::Gofer::Transport::null - DBD::Gofer client transport for testing
     
    

    SYNOPSIS

      my $original_dsn = "..."
      DBI->connect("dbi:Gofer:transport=null;dsn=$original_dsn",...)
    
    

    or, enable by setting the DBI_AUTOPROXY environment variable:

      export DBI_AUTOPROXY="dbi:Gofer:transport=null"
    
    
     

    DESCRIPTION

    Connect via DBD::Gofer but execute the requests within the same process.

    This is a quick and simple way to test applications for compatibility with the (few) restrictions that DBD::Gofer imposes.

    It also provides a simple, portable way for the DBI test suite to be used to test DBD::Gofer on all platforms with no setup.

    Also, by measuring the difference in performance between normal connections and connections via "dbi:Gofer:transport=null" the basic cost of using DBD::Gofer can be measured. Furthermore, the additional cost of more advanced transports can be isolated by comparing their performance with the null transport.

    The "t/85gofer.t" script in the DBI distribution includes a comparative benchmark.
