New submission from Florian Apolloner <florian@apolloner.eu>: Alex asked me to open the bug, I am myself not 100% sure it's pypy's fault -- but I am somewhat out of debugging options. Django's testsuite gets a lot of memory allocation errors under pypy like: ====================================================================== ERROR: test_complex_app (admin_scripts.tests.ManageValidate) manage.py validate does not raise an ImportError validating a complex app with nested calls to load_app ---------------------------------------------------------------------- Traceback (most recent call last): File "/home/florian/sources/django.git/tests/admin_scripts/tests.py", line 1073, in test_complex_app out, err = self.run_manage(args) File "/home/florian/sources/django.git/tests/admin_scripts/tests.py", line 176, in run_manage return self.run_test('./manage.py', args, settings_file) File "/home/florian/sources/django.git/tests/admin_scripts/tests.py", line 140, in run_test universal_newlines=True).communicate() File "/home/florian/sources/pypy-c-jit-63155-972e776a277f-linux64/lib-python/2.7/subprocess.py", line 679, in __init__ errread, errwrite) File "/home/florian/sources/pypy-c-jit-63155-972e776a277f-linux64/lib-python/2.7/subprocess.py", line 1147, in _execute_child self.pid = os.fork() OSError: [Errno 12] Cannot allocate memory This is on a 64 bit machine with 4 Gig of RAM, once in a while even oom_killer hits it… I am also seeing segfaults on the ci-server, but those appear to be fixed with the recent nightlies. ---------- messages: 5551 nosy: apollo13, pypy-issue priority: critical status: unread title: Major regression since 2.0 beta ________________________________________ PyPy bug tracker <tracker@bugs.pypy.org> <https://bugs.pypy.org/issue1445> ________________________________________
