CDEV Debugging

By J. Peter Hoddie, Palo Alto, CA

A cdev Shell

This article describes a shell program created to simplify the process of writing, testing, and debugging Control Panel devices. The shell is written in MPW Pascal (actually it was developed in TML Pascal II, but the two are compatible) and so is appropriate for use with cdev’s written in the MPW environment. The cdev shell has been tested with Apple’s SADE debugger. This article does not describe how to write a cdev. For the details on writing a cdev, including a working example, see Inside Macintosh Volume 5.

Without a cdev shell, the process of testing a cdev is less then simple. You must compile and link the cdev, place it in the system folder, and select the Control Panel. Under these circumstances you cannot use a source level debugger, only MacsBug. Using the cdev shell, you simply link your cdev with the shell code and run it as a normal application which gives you access to a source level debugger. The cdev shell has several features designed specifically for testing. The shell itself does not appear graphically identical to the Control Panel, however as far as the cdev itself is concerned there is no difference.

The cdev shell was designed not only to allow the use of a source level debugger, but also to provide a collection of features for easily testing the many messages to which a cdev is expected to respond. Further, because as you are developing a cdev you may not have written code to handle each messages, a dialog presented from the “Message Masks...” menu item allows you to filter out any combination of cdev messages. Your message mask settings are stored as a resource type ‘msks’ so that you don’t have to reset them each time you use the shell.

An option to force the cdev to update its entire window to test your drawing code is available as the “Force Update” menu item.

A small window named “Other Window” appears above and to the right of the Control Panel window. This window allows you to test the activate and deactivate messages by making the “Other Window” the active window. By covering areas of your cdev’s panel with the “Other Window” you can further test the screen updating capabilities of your cdev.

All of the options on the standard Edit menu are passed to the cdev as the corresponding cdev messages.

When you start up the cdev shell, the test cdev is not selected. Either click on its icon or select Open from the file menu. To close the cdev, select Close from the file menu or click on the stop sign icon. This allows you to test the open and close cdev messages multiple times without having to relaunch the cdev shell. By not immediately selecting the test cdev in the shell, you have the opportunity to set break points, modify the message masks, and perform any other required actions.

Tech Note #215 - “New” cdev Messages - describes a cdev message, cursorDev, that is not documented in Inside Macintosh. It states that if a ‘CURS’ -4064 (cursor) resource is present in the cdev file, that the cdev will receive a cursorDev message (number 14) whenever the cursor is inside the cdev’s window. This allows the cdev to have its own cursor as appropriate. The shell fully supports this new message.

The shell also checks that certain required resources are present. If a required resource is missing, an error message is generated and the shell aborts. The cdev resources that the shell must have to run are ‘DITL’, ‘mach’, ‘nrct’, and ‘ICN#’ all with ID -4064. The only required resources that the shell does not check for are the ‘cdev’ code, ‘BNDL’ and ‘FREF’ resources.

The shell does other error checking as appropriate. For example, the macDev message is only allowed to return one of two values. If any other value is returned, the shell issues a warning alert.

The shell will only send the cdev the macDev message if the values of the hard and soft masks in the ‘mach’ -4064 resource are set as documented in Inside Macintosh. Otherwise the shell compares these to HwCfgFlags and ROM85 in low memory as described in Inside Macintosh. While Inside Macintosh claims that HwCfgFlags is a low memory global, its location is never given. I had to fish it out of one the “private” MPW Assembler equates files.

This article does not include a sample cdev to use with the shell. It is currently set up to work with the Sample provide in Inside Macintosh Volume 5. The only call the cdev shell makes to code outside itself is to the entry point of the cdev unit that is being tested. The name of the unit that the cdev shell expects to find is “cdev” and the name of the main cdev routine (really its entry point) is “Sample” - exactly as the sample unit in Inside Macintosh.

There is one minor bug in the Sample cdev from Inside Macintosh. In the function EnoughRoomToRun the call to GetResource should be replaced with a call to RGetResource or the cdev will not run.

The shell is not a great example of how to write a Macintosh application. It clearly demonstrates what Tech Note #203 - Don’t Abuse the Managers - tries to drive home: the Dialog Manager is not a user interface! Unfortunately, since the Control Panel relies on the Dialog Manager, there was no choice for the cdev shell. Also, the shell was originally written in THINK C, and then translated to Pascal when I found out that a cdev shell was shipping with THINK C Version 4. Anyone who is interested in the C version may contact me directly for a copy. Converting the code presented in this article to run under THINK Pascal should be an easy task.
