List Index Out of Range in message.py

[Tom Westrick]

Can anyone point me in the right direction in fixing "IndexError: list index out of range"? Bots is failing on an XML file the first time it reads it in. If I re-process it, it runs fine which is why I am not sure what is wrong. It is also successful if I re-queue the original file.

Here is the full stacktrace:

Traceback (most recent call last):
  File "c:\python27\lib\site-packages\bots\transform.py", line 71, in _translate_one_file
    edifile.checkforerrorlist() #no exception if infile has been lexed and parsed OK else raises an error

Complete guess here but if it works 'at a later point' I often look for either permission issues, virus scanners locking up the file (if on Windows) or some db lockup timing issue, etc. Some sort of OS I/O related issue...

[Tom Westrick]

It is a Windows server but it is not running any virus software.

Can anyone point to what this error is from? I looked at the code but wasn't quite following in message.py.

hi Tom,

this is an issue with the grammar of that xml file.

I am not sure about what problem this is.
if I understand you right this failed once, and after that it did not fail any more? or is this reproducable?

kind regards,
henk-jan

It is reproducible but it runs fine if that is the only route being run. I am sharing recorddefs for common "objects" by including them using recorddefs.update(messages_grammar.recorddefs). This works in most cases except this one. I've temporarily fixed it by not using recorddefs.update in certain spots. A plugin would probably be best for me to create than to explain how I set it up :)

yes, that does not work.
what do you want to achieve here?

My goal was to not have to duplicate shared recorddefs in multiple files. Most of my XML files represent C# classes which share many of the same data types. I am able to use recorddefs.update in most cases which seems to work fine. It was just one specific grammar where it was throwing the list index out of range error. I just duplicated some recorddefs to fix the problem. I am good for now! Thanks!
