Hi, Since some weeks in one Applevel-test is failing consitently on the buildbot: module/posix/test/test_posix2.py with the failure: if sys.platform.startswith('linux'):
assert hasattr(st, 'st_rdev') E assert hasattr(posix.stat_result(st_mode=33152,st_ino=1588275L, st_dev=64256L, st_nlink=1,s...integer_atime=1314759734, _integer_mtime=1314759734,_integer_ctime=1314759734), 'st_rdev') module/posix/test/test_posix2.py:135: AssertionError ================ 1 failed, 77 passed, 6 skipped in 4.80 seconds ================ So it seems that st_rdev is not available
I tracked this problem down to a chicken-egg problem. The relevant portion is here in pypy/rpython/module/ll_os_stat.py: # for now, check the host Python to know which st_xxx fields exist STAT_FIELDS = [(_name, _TYPE) for (_name, _TYPE) in ALL_STAT_FIELDS if hasattr(os.stat_result, _name)] As pypy is meanwhile build with pypy, relying on the host python is not a good idea. A pypy without st_rdev will again build only a new pypy without st_rdev, even if the platform supports st_rdev. As an experiment I bootstrapped pypy again with python an the error disappered # python translate.py -O2 targetpypystandalone.py # ./pypy-c ../../../pytest.py ../../module/posix/test/test_posix2.py -A ========================= test session starts ========================== platform linux2 -- Python 2.7.1[pypy-1.6.0] -- pytest-2.1.0.dev4 pytest-2.1.0.dev4 from /home/boemmels/src/pypy/pytest.pyc collected 80 items ../../module/posix/test/test_posix2.py ...........................................................s............ ........ ================= 79 passed, 1 skipped in 5.07 seconds ================= This bootstrapped pypy-c is also cappable of rebuilding an pypy with st_rdev enabled. But this is not a clean solution. I think the way to go is to no longer rely on the Host-Python, but use the appropiate configure magic. Something like #ifdef HAVE_STRUCT_STAT_ST_RDEV but in a pythonic way. Unfortunatly I'm not familar with pypy's configuration system so I got stuck here. Can anybody tell me how to test for available struct members like AC_CHECK_MEMBERS([struct stat.st_rdev]) in autoconf?
