2.0.3: pytest is failing in `test/test_Exceptions.py::TestUtil::test_hresult` unit

[kloczek]

Your system information

• Operating system used: Linux x86/64
• pyscard version: pcsc-lite 1.9.5
• Python version: 3.8.13

Please describe your issue in as much detail as possible:

I'm trying to package your module as an rpm package. So I'm using the typical build, install and test cycle used on building packages from non-root account.

• "setup.py build"
• "setup.py install --root </install/prefix>"
• "pytest with PYTHONPATH pointing to sitearch and sitelib inside </install/prefix>

Here is pytest output:

[LudovicRousseau]

2148532243 is SCARD_F_COMM_ERROR

Please generate a pcscd log as described at https://pcsclite.apdu.fr/#support

[kloczek]

So I'm guessing that as long as there is no physical card to test this unit may fail? Am I right? 🤔

[LudovicRousseau]

No, you are wrong. Please generate and send me a pcscd log.

[LudovicRousseau]

@kloczek I have no new since 6 days. I need the pcscd log to try to understand what is happening.

[kloczek]

Sorry I was busy. Will try to provide details today evening or tomorrow.

00000005 [140231278573696] pcscdaemon.c:484:main() Another pcscd (pid: 3916054) seems to be running.

Does it mean that pcscd needs to be started before start pytest?

[LudovicRousseau]

1. Kill/stop any running pcscd process
2. Start pcscd to generate the log
3. run pytest

[kloczek]

Issu is that I'm running all my builds in LXC zones which have no access to many phisical subsystems.

[LudovicRousseau]

"Another pcscd (pid: 3916054) seems to be running." so a pcscd process is already running (or is available) in your LXC.

You can also try to build and run the tests outside your LXC. You do not need to install PySCard. Just run make and make test.

[LudovicRousseau]

Have you tried what I suggested?

[LudovicRousseau]

Any news? Have you found a solution?

[LudovicRousseau]

No news since 4 months. Closing.

[kloczek]

Just tested 1.0.4 and looks like it works now
