Hi Sudip!
I reviewed the patch, and I have a few questions:
- The patch seems to be one of the commits of the MR accepted on Debian
on 976439 (the last one in fact). Would the commit
a7ac2dbdc122115b5603f595c56cc55a6f09dca3 "Also add libwiicd patches. "
be needed?
- The patch is for commit https://salsa.debian.org/georgesk/cwiid/-/blob/e7cebe40c94b05e97f07302c36e93f60482b0ae5/debian/patches/python3-build-azzra, but is not completely imported:
- Makefile.in is not imported in the patch (maybe is this related to the commit a7ac2db (the one I pointed to in the previous question?)
Why are some parts of the original commit (change comments, e.g.) not imported into the patch?
Could you give us more information about this elections?
I build the package with the patch (it builds OK) and I didn't test yet

Title:
[SRU] wminput crashes with ImportError: ... undefined symbol:
PyVarObject_CallFunction
Status in cwiid package in Ubuntu:
Fix Released
Status in cwiid source package in Jammy:
Confirmed
Status in cwiid package in Debian:
Fix Released
Bug description:
[ Impact ]
wminput is completey unusable as it will immediately crash with
undefined symbol error.
$ sudo wminput <any random mac address>
ImportError: /usr/lib/python3/dist-packages/cwiid.cpython-310-x86_64-linux-gnu.so: undefined symbol: PyVarObject_CallFunction
This is mostly because the code was not properly ported to Python-3.
[ Test Plan ]
1. install wminput
2. execute wminput with a mac address
If the package is not fixed, it will fail with undefined symbol error.
Ideally someone with the hardware should test.
[ Where problems could occur ]
There are changes in the code and there are chances of regression due
to this change. But wminput as of now is already unusable, so any
regression can not be worse than that.
[ Other Info ]
The patch, even though looks big is mostly changing all the PyVarObject to PyObject, and few other changes.
Initially I tried to pick only the changes for PyVarObject but that resulted in errors for PyInt_FromLong. After fixing that, errors from PyCObject_Check appeared. So, I thought its best to use all the fixes from the Debian patch.
[ Original Bug Description ]
When trying to invoke wminput I get the following:
james at thelio:~$ sudo wminput [redacted MAC address]
ImportError: /usr/lib/python3/dist-packages/cwiid.cpython-310-x86_64-linux-gnu.so: undefined symbol: PyVarObject_CallFunction
This is a duplicate of 1958466, but I could not run apport-collect
against it because it was not my bug. Since it's been orphaned for
over a year, I made this bug and ran apport-bug to file it. I'm happy
to provide any additional data.
