Debugging

This server has the interesting ability to reload parts of its implementation dynamically. This lets you add features and fix bugs without ever restarting. It is even possible to setup a debug session with TclPro. This is made possible with the help of the /debug URL. The debug module has e.g. several useful URLs that let you examine variable values and other internal state.

The /debug URLs are:

/debug/source?source=<value>&thread=<value>

/debug/package?package=<value>

/debug/pvalue?aname=<value>

/debug/parray?aname=<value>

/debug/raise?args

/debug/after

/debug/echo?title=<value>&args

/debug/errorInfo?title=<value>&errorInfo=<value>&no=<value>

/debug/dbg?host=<value>&port=<value>

/debug/showproc?showproc=<value>

/debug/disable

For more specific information about the calls see the debug module.

Some examples:

TclPro

It is also possible to debug tclhttpd with TclPro. Briefly you have to perform following steps:
Enable the tclhttpd server for debugging (see httpdthread.tcl).
Setup a Project in TclPro with Debugging Type "Remote Debugging"; define the portnumber; start TclPro by calling

http://yourserver:port/debug/dbg?host=<hostname>&port=<portnumber>

The tclhttpd server will connect to a TclPro Session running on host <hostname> listening for remote connections on port number <portnumber>
In case TclPro is running on the "localhost" listening for the default portnumber "2576" it is enough to call

http://yourserver:port/debug/dbg
