Manually Configured Remote Debugging

Index of All Documentation » Wing Pro Reference Manual » Advanced Debugging Topics »


This section describes how to manually configure remote debugging with wingdbstub. These instructions are needed only if you cannot use the Remote Hosts feature. In most cases, you will want to follow the much simpler instructions in Debugging Externally Launched Remote Code instead.

One alternative to consider before getting started is installing Wing on the remote host and using remote display of the IDE via Remote Desktop (Windows), Screen Sharing (OS X), or X Windows (Linux/Unix).

See also the Manually Configured Remote Debugging Example.

(1) First set up Wing to successfully accept connections from another process within the same machine, as described in section Importing the Debugger. You can use any Python script for testing this until you have values that work.

(2) Optionally, alter the Server Host preference to the name or IP address of the network interface on which the IDE listens for debug connections. The default server is None, which indicates that the IDE should listen on all the valid network interfaces on the host.

(3) Optionally, alter the preference Server Port to the TCP/IP port on which the IDE should listen for debug connections. This value may need to be changed if multiple copies of Wing are running on the same host.

(4) Set the Allowed Hosts preference to include the host on which the debug process will be run. For security purposes, Wing will reject connections if the host isn't included here.

(5) Configure any firewall on the system that Wing is running on to accept a connection on the server port from the system that the debug process will run on.

(6) Next install Wing on the machine on which you plan to run your debug program. Creating an entire Wing installation is the easiest approach. Alternatives are to copy only the debug server code out of a Wing installation on the same type of OS or to compile the debugger core from source code. For details, see Manually Installing the Debugger Core.

(7) Next, transfer copies of all your debug code so that the source files are available on the host where Wing will be running and at least the *.pyc files are available on the debug host.

During debugging, the client and server copies of your source files must match or the debugger will either fail to stop at breakpoints or stop at the wrong place, and stepping through code may not work properly.

You will need to use Samba, FTP, NFS, or some other file sharing or file transfer mechanism to keep the remote files up to date as you edit them in Wing.

If files appear in different disk locations on the two machines, you will also need to set up a file location map, as described in Manually Configured File Location Maps.

(8) On your debug host, copy into the same directory as your source files and import it in your Python source as described in Debugging Externally Launched Code.

(9) If you didn't copy out of a complete installation of Wing on the debug host, or if working on OS X or with the zip file or tar file installations of Wing, you will need to set WINGHOME in your copy to match the location where you have copied the debug server code on your debug host.

(10) In on your debug host, set kWingHostPort. The host in this value must be the IP address of the machine where Wing is running. The port must match the port configured with the Server Port preference on the host where Wing is running.

(11) Then restart Wing and try running your program on the debug host. You should see the Wing debugger status icon change to indicate that a debug process has attached.

If you have problems making this work, try setting kLogFile variable in for log additional diagnostic information.
