boto3 S3 in Windows COM object

[lbate...@gmail.com]

I'm rewriting a working COM object and upgrading it from boto to boto3 because older version was unable to connect properly with newer regional endpoints. I've worked around the problem where boto3 needs to know where some external files:

aws_data_files = [('data', ['data/_endpoints.json',

                            'data/_retry.json',

                            'data/cacert.pem']),

                  

                  ('data/s3/2006-03-01', ['data/s3/2006-03-01/service-2.json',

                                          'data/s3/2006-03-01/paginators-1.json',

                                          'data/s3/2006-03-01/waiters-2.json'])

                 ]

are located when the program is frozen with py2exe and for normal program this works fine. I've spent about 8 hours trying to figure out where these files should be located when you are using boto3 from inside a Windows COM object. It is unclear where the "data" folder should be placed when you are running inside a COM object and I can't find a workaround that would allow me to explicitly include these files.

I keep getting the following traceback:

Python COM server Internal Error: Unexpected Python Error: Traceback

Any help would be greatly appreciated.

I added some code to the COM object and have determined that COM objects run with C:\Windows\System32 as their current directory. Give that information I figured that if I put the /data folder in that folder this would work, but it does not.

IMHO the method for getting these files included in a "frozen" working program needs to be refactored. I would REALLY prefer being able to do an EXPLICIT include when/if I require these files instead of the dynamic inclusion that is currently employed.
