Hi, python has a memory leak in the test for test_socket.py, and it was fixed in commit 90aeaee861845142843a0f988fa4ff016c723cdb.
https://git.savannah.gnu.org/cgit/guix.git/commit/?id=90aeaee861845142843a0f988fa4ff016c723cdb More information from IRC: ----8<------------------------------------------------------------ <mbakke> There is a bug in Python 3 which causes the test suite to run out of memory on recent kernels: https://bugs.python.org/issue34587 <mbakke> Unfortunately the only workaround I can think of is removing "/tmp/guix-build-python-3.6.5.drv-0/Lib/test/test_socket.py" some time during the build (but before the check phase). ----8<------------------------------------------------------------ However, python-minimal still runs test_socket, causing a memory leak. Is it possible to change python-minimal so it uses python-3/fixed? I was able to successfully build python-minimal by appending the fix to python-minimal, as below. I do not know how (replacement python-3/fixed) interacts with python-minimal. ----8<------------------------------------------------------------ (define-public python-minimal (package/inherit python (name "python-minimal") (outputs '("out")) ;; Build fails due to missing ctypes without libffi. ;; OpenSSL is a mandatory dependency of Python 3.x, for urllib; ;; zlib is required by 'zipimport', used by pip.
