NAME

Devel::RemoteTrace - Attachable call trace of perl scripts

SYNOPSIS

$ perl -d:RemoteTrace your-script

or

$ perl -d:RemoteTrace=:trace your-script

or

use Devel::RemoteTrace;

DESCRIPTION

This module implements a perl debugger that sends a call trace of the debugged perl script to a remote destination via UDP. The default is to send to localhost:9999.

By using UDP the debug process doesn't have to care aboput if any body is listening. It just sends the trace messages.

Tracing is enabled and disabled bysending the traced process ans SIGUSR2. If the module is called with ':trace' as argument tracing is enabled from the beginning

ENVIRONMENT

RemoteTrace uses the followin environment variables:

DEBUG_ADDR

DEBUG_PORT

The hostname and port to send the call trace to.

BUGS, FEATURES, AND OTHER ISSUES

Using this on untrusted networks might leak security related information

Due to the nature of UDP there is no guarantee that the receiver gets all function calls. This could be "fixed" by adding a sequence number.
