NAME

6       dbilogstrip - filter to normalize DBI trace logs for diff'ing
7

SYNOPSIS

9       Read DBI trace file "dbitrace.log" and write out a stripped version to
10       "dbitrace_stripped.log"
11
12         dbilogstrip dbitrace.log > dbitrace_stripped.log
13
14       Run "yourscript.pl" twice, each with different sets of arguments, with
15       DBI_TRACE enabled. Filter the output and trace through "dbilogstrip"
16       into a separate file for each run. Then compare using diff. (This
17       example assumes you're using a standard shell.)
18
19         DBI_TRACE=2 perl yourscript.pl ...args1... 2>&1 | dbilogstrip > dbitrace1.log
20         DBI_TRACE=2 perl yourscript.pl ...args2... 2>&1 | dbilogstrip > dbitrace2.log
21         diff -u dbitrace1.log dbitrace2.log

DESCRIPTION

24       Replaces any hex addresses, e.g, 0x128f72ce with "0xN".
25
26       Replaces any references to process id or thread id, like "pid#6254"
27       with "pidN".
28
29       So a DBI trace line like this:
30
31         -> STORE for DBD::DBM::st (DBI::st=HASH(0x19162a0)~0x191f9c8 'f_params' ARRAY(0x1922018)) thr#1800400
32
33       will look like this:
34
35         -> STORE for DBD::DBM::st (DBI::st=HASH(0xN)~0xN 'f_params' ARRAY(0xN)) thrN
