--- Begin Message ---Package: src:pyzoltan Version: 1.0.1-5 Severity: important Tags: ftbfs Dear maintainer: During a mass-rebuild of all packages in bookworm, this package failed to build in this way: [...]raise RuntimeError(msg)E RuntimeError: test geometric_partitioner.py failed with returncode 1 pyzoltan/tools/run_parallel_script.py:54: RuntimeError ----------------------------- Captured stdout call ----------------------------- running test: ['mpiexec', '-n', '2', '/usr/bin/python3.11', '/<<PKGBUILDDIR>>/.pybuild/cpython3_3.11_pyzoltan/build/pyzoltan/core/tests/geometric_partitioner.py'] -------------------------------------------------------------------------- There are not enough slots available in the system to satisfy the 2 slots that were requested by the application: /usr/bin/python3.11 Either request fewer slots for your application, or make more slots available for use. [...] Apparently the package is assuming I have at least 2 CPUs, but I have only one, and build-essential does not imply multi-core. I tried to fix this by honoring parallel=n in DEB_BUILD_OPTIONS, since that's the recommended way to support parallelism when building Debian packages. The result is in the attached patches, but they don't work. When I use those patches, build with a single-cpu now works, but build in my desktop PC, which has 6 cores (12 threads) fails in this way: --------------------------------------------------------------- pyzoltan/tools/run_parallel_script.py:56: RuntimeError ----------------------------- Captured stdout call ----------------------------- running test: ['mpiexec', '-n', '12', '/usr/bin/python3.11', '/<<PKGBUILDDIR>>/.pybuild/cpython3_3.11_pyzoltan/build/pyzoltan/core/tests/geometric_partitioner.py'] -------------------------------------------------------------------------- There are not enough slots available in the system to satisfy the 12 slots that were requested by the application: --------------------------------------------------------------- Considering that the package takes less than one minute to build, my proposal to fix this (for everybody) would be to just disable parallelism. Honoring parallel=n in DEB_BUILD_OPTIONS makes sense for big packages (or even medium-sized). For small packages like this one, there is not a great saving. To reproduce the problem please try GRUB_CMDLINE_LINUX="nr_cpus=1", that's an extremely easy way to test it in a machine with a single CPU. [ Note: I'd like to fix this in stable, and I will gladly care about the stable upload, but once we know how to fix this properly in trixie/sid ].
