NAME

       dbilogstrip - filter to normalize DBI trace logs for diff'ing

SYNOPSIS

       Read DBI trace file "dbitrace.log" and write out a stripped version to "dbitrace_stripped.log"

	 dbilogstrip dbitrace.log > dbitrace_stripped.log

       Run "yourscript.pl" twice, each with different sets of arguments, with DBI_TRACE enabled. Filter the output and trace through "dbilogstrip"
       into a separate file for each run. Then compare using diff. (This example assumes you're using a standard shell.)

	 DBI_TRACE=2 perl yourscript.pl ...args1... 2>&1 | dbilogstrip > dbitrace1.log
	 DBI_TRACE=2 perl yourscript.pl ...args2... 2>&1 | dbilogstrip > dbitrace2.log
	 diff -u dbitrace1.log dbitrace2.log

DESCRIPTION

       Replaces any hex addresses, e.g, 0x128f72ce with "0xN".

       Replaces any references to process id or thread id, like "pid#6254" with "pidN".

       So a DBI trace line like this:

	 -> STORE for DBD::DBM::st (DBI::st=HASH(0x19162a0)~0x191f9c8 'f_params' ARRAY(0x1922018)) thr#1800400

       will look like this:

	 -> STORE for DBD::DBM::st (DBI::st=HASH(0xN)~0xN 'f_params' ARRAY(0xN)) thrN
