python-trio 0.24.0-1 FTBFS on noble

[Pushkar Kulkarni]

Build-time tests fail due to, what appears like, a permissions issue with setsockopt() only on the LP builders [1] (the failure can be repro'd in a PPA [2]). However, I couldn't repro the failure in a noble-amd64 schroot, using sbuild - the package built there.

Well, looks like the tests that fail use SO_BINDTODEVICE (which needs root privileges).

[Pushkar Kulkarni (pushkarnk)]

I am not 100% sure if this call, failing with a PermissionError, requires root privileges:

sock.setsockopt(tsocket.SOL_SOCKET, tsocket.SO_BINDTODEVICE, None, 0)

I tried to write small tests in Python and C, as a non-root user, but cannot trigger a PermissionError (Python) or a system-call failure (C).

I am unable to reproduce the build-time test failure too.

Checked with the Launchpad team if I could get access to a builder VM so that we can investigate this failure, but they hinted on the negative side.

I might try to run the build in a noble LXD-container (on a VM), like LP does. But, I have submitted a patch that disables the failing call from the tests, as a temporary workaround to get python-trio built and also potentially not block other packages like dnspython [1].

This bug was fixed in the package python-trio - 0.24.0-1ubuntu1

---------------
python-trio (0.24.0-1ubuntu1) noble; urgency=medium

  * d/patches: In test_socket.py, handle PermissionError
    which may be thrown if setsockopt() is invoked
    with SO_BINDTODEVICE (LP: #2054772)
