![]() ![]() China recently moved to tax its own virtual currency trade - Western governments may not be far behind. But if the idea of buying real world goods with virtual currencies catches on, expect a raft of new regulation to follow suit. Of course, IMVU Music is only just debuting today, and the number of IMVU users with serious profits is tiny. How can a company like Amazon (AMZN), which also offfers DRM-free music, compete with that? But buying real-world things with virtual profits before cashing out makes an end-run around tax laws, because virtual world companies don't report profits to the IRS - only PayPal does. Doing so keeps virtual world economies as closed ecosystems and leaves a paper trail (usually via a service like PayPal) a tax authority could follow. Previously, if you had a profitable business in a virtual world (and more than a handful of people make their full-time, real-world income doing nothing but running businesses in games like IMVU or Second Life) in order to buy anything "real" you had to convert your game profits into something like U.S. The next post in this series will cover automatic detection of errors in our C++ libraries.Account icon An icon in the shape of a person's head and shoulders. it called C++ writing and it make iMVU Program Windows crashing, DLL need to be removed from the program IMVU WINDOWS. This is the main gist of how the IMVU client automatically reports failures. The codes that Imvu need to remove in their program: Codes, every code with DLL (space.) +, , > or > + ect. In our current implementation, we post the error report to a Bugzilla instance, where we have built custom tools to analyze and prioritize the failures in the field. This time, if a bug in updateAnimations() raises an exception, the top-level try: except: clause catches the error and handles it intelligently. (Unfortunately, most of the software out there asks users to do exactly this!) We need a way for the client to automatically handle errors and prompt the users to submit the reports back to us. It's just too much work - they will simply stop using our product. ![]() We can't be asking our users to manually hunt down some log files on their hard drives and mail them to us. Please see ."įrom a crash reporting standpoint, this is not good enough. Thus, the py2exe bootstrap code registers a handler so that errors are logged to a file, and when the program shuts down, a dialog box shows something like "An error has been logged. With an unmodified py2exe application, uncaught exceptions are printed to sys.stderr (as above), except there is no console window to display the error. That's all great, but our users don't launch our client by invoking python from the command line: we use py2exe to build a standalone executable that users ultimately run. If running the client with a standard command-line python invocation, the program would print the exception and stack trace to the console window and exit. ![]() Let's imagine that updateAnimations() has a bug and occasionally raises an uncaught exception. This structure assumes that no exceptions bubble into or out of the main loop. PumpWindowsMessages() # for 1/30th of a second Since the client is a cross between a normal interactive Windows program and a real-time game, the main loop looks something like this: The IMVU client is written primarily in Python, with time-critical components such as the 3D renderer written in C++. Now let's talk a little bit about how the client is structured. Counterintuitively, crashing the program forces us to act on crashes and immediately exposes bugs that might trigger unwanted behavior or lost data down the road. You might wonder why we crash the program whenever anything goes wrong rather than trying to catch the error and continue running. ![]() As part of the crash report, we send log files, stack traces, system information, and anything else that might help us debug the failure. This first article will give a bit of background on the structure of the client and show how we handle Python exceptions.Īt IMVU, we generally subscribe to the Fail Fast philosophy of handling errors: when the client encounters an unexpected error, we immediately crash the program and ask the user to submit a crash report. For years now, I have been meaning to write a series of articles on the automated crash reporting system in the IMVU client. ![]()
