## 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](https://www.chedong.com/phpMan.php/perldoc/DBD%3A%3ADBM%3A%3Ast/markdown) ([DBI::st](https://www.chedong.com/phpMan.php/perldoc/DBI%3A%3Ast/markdown)=[HASH(0x19162a0)](https://www.chedong.com/phpMan.php/man/HASH/0x19162a0/markdown)~0x191f9c8 'f_params' [ARRAY(0x1922018)](https://www.chedong.com/phpMan.php/man/ARRAY/0x1922018/markdown)) thr#1800400

       will look like this:

         -> STORE for [DBD::DBM::st](https://www.chedong.com/phpMan.php/perldoc/DBD%3A%3ADBM%3A%3Ast/markdown) ([DBI::st](https://www.chedong.com/phpMan.php/perldoc/DBI%3A%3Ast/markdown)=[HASH(0xN)](https://www.chedong.com/phpMan.php/man/HASH/0xN/markdown)~0xN 'f_params' [ARRAY(0xN)](https://www.chedong.com/phpMan.php/man/ARRAY/0xN/markdown)) thrN
