hi, the bytearray tests are broken when chars are unsigned. tests/run/bytearraymethods.pyx defines following function: def bytearray_append(b, char c, int i, object o):
this gets converted to an effective __Pyx_PyInt_AsUnsignedChar which then errors out when -1 is passed in. chars are unsigned like they are by default on arm, s390x and powerpc. This causes a couple build failures in debian: https://buildd.debian.org/status/package.php?p=cython https://buildd.debian.org/status/fetch.php?pkg=cython&arch=armel&ver=0.20-1&stamp=1390316252 the tests can be fixed by adding signed char to the interface. to reproduce on x86 with gcc (note the -funsigned-char to change the default): cython tests/run/bytearraymethods.pyx gcc -funsigned-char bytearraymethods.c -fPIC $(python-config --includes) $(python-config --libs) -shared -O2 -o bytearraymethods.so python -c "import doctest; import bytearraymethods; doctest.testmod(bytearraymethods)" Traceback (most recent call last): File "<string>", line 1, in <module> NameError: name 'bytearraymethods' is not defined root@ubuntu:/# python -c "import doctest; import bytearraymethods; doctest.testmod(bytearraymethods)" ********************************************************************** File "bytearraymethods.so", line ?, in bytearraymethods.__test__.bytearray_append (line 202) Failed example: b = bytearray_append(b, -1, ord('y'), ord('z')) # doctest: +ELLIPSIS Expected: Traceback (most recent call last): ValueError: ...
