How to solve the Error “maximum execution iteration execeed”

[Han Yang]

Hi, 

I would like to test if we could use Blockly to realize Encryption algorithm -- DES algorithm.

There are plenty of Blocks and when I run the program, there is an error : Maximum execution iteration execeed , how could I solve this problem.

Thanks for your time!

This doesn't appear to be a blockly bug, but rather a protection in the interpreter to prevent infinite loops. Without further details, I'm not clear which interpreter. Googling "Maximum execution iteration exceed", I see similar errors in PHP, Google's app script, and SaleForce's platform.

If was a JavaScript in the web environment, I'd suggest web workers, or otherwise break the iteration into a sequence of multiple loops, chained together via JavaScript's setTimeout(). I'm sure your platform has something similar.

What browser/environment are you using?  Where are you executing this code?  I don't recognize this exact error message.

Firefox uses the message "InternalError: too much recursion" when the stack is 50,000 levels deep.

Chrome uses the message "Maximum call stack size exceeded" when the stack is 19,000 levels deep.

Safari reloads the page without warning when the stack is 3,000 levels deep.
