[issue2263] struct.pack() + numpy int raises SystemError

2013-07-16 Thread Yury V. Zaytsev 

Yury V. Zaytsev added the comment:

As noted in issue5476, I've submitted a pull request for NumPy: 
ttps://github.com/numpy/numpy/pull/3526 .

I hope that this fixes this problem too: on Py2, I've added 
Py_TPFLAGS_INT_SUBCLASS, on Py3, NumPy doesn't inherit from int anymore, 
because it's not a fixed-width integer type.

I guess it makes sense to close this bug now.

FYI Py_TPFLAGS_INT_SUBCLASS already not used in Python 3.x.

issue5476 has a problem with timedelta(microseconds = int32(36))

interestingly 0 to 35 work , if the patch for this issue2263 is applied.

engelbert gruber grub...@users.sourceforge.net added the comment:

Including Py_TPFLAGS_INT_SUBCLASS in numpy's BASEFLAGS cures this.
This is an external problem then.
But I could not find any reference to Py_TPFLAGS_*_SUBCLASS in the
documentation, that is a python problem.

Ok, so Python has to improve its C-API documentation, and numpy to fix
its int types :)

[issue2263] struct.pack() + numpy int raises SystemError

2009-02-09 Thread engelbert gruber 

engelbert gruber grub...@users.sourceforge.net added the comment:

in 2.7 svn _struct.c 

formatdef native_table[] = {
  {'B',   sizeof(char),   0,  nu_ubyte,   np_ubyte},
formatdef bigendian_table[]
  {'B',   1,  0,  nu_ubyte,   bp_uint},
formatdef lilendian_table[]
{'B',   1,  0,  nu_ubyte,   lp_uint},

np_ubyte calls get_long b/lp_uint call get_wrapped_ulong which calls
#define PyInt_Check(op) \
  PyType_FastSubclass((op)-ob_type, Py_TPFLAGS_INT_SUBCLASS)

but ob_type is set to BASE flags INT_SUBCLASS i snot set.

on ubuntu 8.04, Python 2.7a0 (trunk:69044) and numpy 1.2.1
(. is OK, e means SystemError)

* signed always works, longlong also.
* unsigned native works half of the time
* unsigned little/big endian never works
* the numpy type does seam to have any effect.

[issue2263] struct.pack() + numpy int raises SystemError

2008-03-10 Thread Just van Rossum 

New submission from Just van Rossum [EMAIL PROTECTED]:

struct.pack() raises SystemError when fed a numpy integer in some cases. 
The following was run on MacOSX 10.4, little endian (I can only 
reproduce the error if I specify big endian for the struct format). Not 
sure if this could be a numpy bug.
