<title>Overview</title>

<para>
|
|
This module provides an interactive config file debugger. It can print
|
|
a trace of config script execution for a SIP message to log and set
|
|
breakpoints on every script action, allowing step-by-step execution of
|
|
the routing and response scripts.
|
|
</para>
|
|
<para>
|
|
Debugging can be done from local or remote host via RPC interface (e.g.,
|
|
XMLRPC, &sercmd;, siremis).
|
|
</para>
|
|
<para>
|
|
The framework to set breakpoints on specific actions and config lines
|
|
is not exported to RPC. Each action can be accompanied by an
|
|
breakpoint or you can use dbg_breakpoint() function to set a breakpoint
|
|
at certain line. Global breakpoints can be enabled/disabled at runtime.
|
|
The script running trace can also be enabled/disabled at runtime.
|
|
</para>
|
|
<para>
|
|
When the SIP router process is stopped at a breakpoint, you can
|
|
investigate the values of any pseudo-variables. Note that some of
|
|
pseudo-variables may produce memory leaks; a fix is planned in the
|
|
future (here fall pseudo-variables with dynamic name such as htable,
|
|
sqlops). References to SIP message, avps, headers, script and shared
|
|
variables are safe.

<title>Usage</title>
|
|
<para>
|
|
A common usage is to investigate the execution path for a specific
|
|
SIP message. Just enable cfg running trace, send the message and
|
|
watch the logs.
|
|
</para>
|
|
<para>
|
|
Another typical usage is to do interactive debugging and run
|
|
each line of the route blocks of the configuration file step-by-step for a
|
|
particular SIP message.
|
|
</para>
|
|
<para>
|
|
You need to connect using &sercmd; (or other RPC client) to &kamailio;.
|
|
Then you can enable cfg breakpoints and send the SIP message. One
|
|
process will be in waiting state ('state' field different than 0 when
|
|
you do dbg.ls). Calling dbg.release will set the other &kamailio;
|
|
processes in no-breakpoint mode so they can process other SIP messages
|
|
without need to interact with them.
|
|
</para>
|
|
<para>
|
|
A process blocked at a breakpoint is waiting for a command. Use
|
|
'dbg.bp next pid' to execute the current action and stop at the next
|
|
one. 'dbg.bp eval pid PV' can be used to retrieve the value of PV. Once
|
|
you are done and want to continue the execution of the config wihtout
|
|
interaction use 'dbg.bp move pid'.

The above example is for a registration with default config for

version 3.1.0, without authentication. Listed fields are:

'c' - config file; 'l' - line; 'a' - internal action id;
|
|
'n' - name of executed action. 'ERROR' prefix is printed
