** Description changed:
+ [Impact]
+
+ * The package python3-pykdl in focal crashes the Python 3 interpreter
+ if any API accepting a str is used.
+
+ * python3-pykdl is used in the ROS robot control software
+ (https://ros.org) based on Ubuntu.
+
+ * The patch is taken from upstream and uses PyUnicode_AsUTF8, as
+ provided by Python 3.
+
+ [Test Case]
+
+ $ python3 -c "import PyKDL; PyKDL.Tree('foobar')"
+ python3:
/build/orocos-kdl-oHbJfL/orocos-kdl-1.4.0/python_orocos_kdl/PyKDL/std_string.sip:52:
int convertTo_std_string(PyObject*, void**, int*, PyObject*): Assertion
`PyUnicode_Check(s)' failed.
+ Aborted (core dumped)
+ $ echo $?
+ 134
+
+ [Regression Potential]
+
+ * The patch is part of upstream git since 2018 [1], Debian bullseye [2]
+ , Ubuntu groovy and has been accepted into Debian buster [3].
+
+ * I don't see a regression potential as is basically the utf-8
+ transition of Python 3.

Dear Maintainer,
The package python3-pykdl crashes the Python 3 interpreter if any API
accepting a str is used. I've tested this using the latest Focal packages.
-
Minimal reproducible example:
$ python3 -c "import PyKDL; PyKDL.Tree('foobar')"
python3:
/build/orocos-kdl-mPkyII/orocos-kdl-1.4.0/python_orocos_kdl/PyKDL/std_string.sip:52:
int convertTo_std_string(PyObject*, void**, int*, PyObject*): Assertion
`PyUnicode_Check(s)' failed.
Aborted (core dumped)
$ echo $?
134
-
There is a patch fixing this issue in this upstream Debian Buster bug:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=956254
Would you be willing to apply that patch in Ubuntu Focal?
-
Cheers,
Shane
