Description:
Unit tests previously working on LibreOffice 6.3 embedded Python fail on LibreOffice 6.4 embedded Python. Upon trying to import "_queue", an ImportError exception is thrown.

A comparison of the code of queue.py with the corresponding code of the current Python 3.8 installation shows a difference which obviously causes the problem. 


 



Steps to Reproduce:
1. Register LibreOffice 6.4 embedded Python 3.7 as Python interpreter in Eclipse PyDev.
2. Execute a formerly working Python unit test.


Actual Results:
The unit test terminates on ImportError exception (Module "_queue" not found).

Expected Results:
The test ends without errors, as under LibreOffice 6.3 embedded Python 3.5.


Reproducible: Always


User Profile Reset: No



Additional Info:
After changing line 17 of 
c:\Program Files\LibreOffice\program\python-core-3.7.6\lib\queue.py, 
everything seems to work. 

Original code as from line 15:

try:
    from _queue import Empty
except AttributeError:
    class Empty(Exception):
        'Exception raised by Queue.get(block=0)/get_nowait().'
        pass

Corrected code that matches my current Python 3.8 installation: 

try:
    from _queue import Empty
except ImportError:
    class Empty(Exception):
        'Exception raised by Queue.get(block=0)/get_nowait().'
        pass
