# dbilogstrip(1p)

filter to normalize DBI trace logs for diff'ing

## 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
```
