📛 NAME

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

🚀 Quick Reference

Use Case	Command	Description
Normalize a DBI trace file for diffing	dbilogstrip dbitrace.log > dbitrace_stripped.log	Read DBI trace file and output a stripped version
Compare two runs with diff	DBI_TRACE=2 perl yourscript.pl ...args... 2>&1 | dbilogstrip > dbitrace1.log	Run script with DBI trace, filter through dbilogstrip, then diff the results

📋 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
