Bug ID: 161331
Summary: XInteractionRequest.getRequest crashes in
XInteractionHandler callback in Python
Product: LibreOffice
Version: 24.2.3.2 release
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: sdk
Assignee: [email protected]
Reporter: [email protected]
Description:
When accessing the request object of the XInteractionRequest parameter in an
XInteractionHandler from Python, the Python interpreter crashes with the error:
"Fatal Python error: a function returned a result with an error set".
The function works normally when called from Java however.
This bug was encountered while working on porting the PasswordContainer tests
from Java to Python (https://gerrit.libreoffice.org/c/core/+/165038). A shorter
sample is attached to the bug report as well, and can be run with
`./instdir/program/python sample.py` via LibreOffice's internal python.
I attempted to debug the problem with gdb, but due to my very limited knowledge
of Python UNO bindings, identifying the exact cause was challenging.
A shot-in-the-dark guess would be that since the result value
MasterPasswordRequest is an exception type, returned through an Any object, the
marshalling code that converts this value from C++ to Python might be causing
the issue.
Steps to Reproduce:
1. Using the LibreOffice internal python, run the attached sample.py script.
Actual Results:
The python interpreter crashes with "Fatal Python error: a function returned a
result with an error set"
Expected Results:
Not crash, and return a valid MasterPasswordRequest object.
Reproducible: Always
User Profile Reset: Yes
