[issue27096] Ability to get random bytes from random.Random (as with os.urandom)
Campbell Barton added the comment: @serhiy.storchaka, while a properly working function that uses getrandbits isn't so complex, its not trivial either. It needs to create smaller chunks and join them (also check zero size case which raises an error if passed). eg: ``` def urandom_from_random(rng, length): if length == 0: return b'' import sys chunk_size = 65535 chunks = [] while length >= chunk_size: chunks.append(rng.getrandbits(chunk_size * 8).to_bytes(chunk_size, sys.byteorder)) length -= chunk_size if length: chunks.append(rng.getrandbits(length * 8).to_bytes(length, sys.byteorder)) result = b''.join(chunks) return result ``` -- ___ Python tracker <http://bugs.python.org/issue27096> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue27096] Ability to get random bits from random.Random (as with os.urandom)
New submission from Campbell Barton: Currently, getting random bits can be done with os.urandom, However recently I was faced with having to make a test (with reproducible behavior), so I needed to replace os.urandom with a random generator that took a seed value. It turns out there are 3 ways (at least) to handle this, but none are really that great. - Create a list, fill with Random.randint(0, 255), then convert to bytes with bytes.join. - Call Random.getrandbits(), then int.to_bytes. - Override urandom at a system level (possible on Linux [0]). While these work, they are either slow (creating a list), non trivial (OS-level) or limited - Random.getrandbits hits internal limits of an int, and accidentally using the int (running repr on it for example, locks up Python), currently CPython will fail to create values above 256mb since bits is limited to INT_MAX [1]. In short, to keep tests running fast, and without messing about and accounting for internal limits of CPython, there isn't a convenient way to get random bits in Python. Since bits are a primitive type and since its already supported by os.urandom, I think its reasonable the random module could support returning random bits. If this is accepted, I can provide a patch for this, I'm just checking to know if the functionality would be accepted. Suggest to call random.randbits(n).

Campbell Barton added the comment: @haypo, I checked available info online and couldn't find any reference to byte file-paths were deprecated since Python3.2.

Since this is already working properly in 3.5 for other systems besides ms-windows, and worked in 3.4x. Dropping support on a single platform seems a rather problematic regression.

[issue16129] No good way to set 'PYTHONIOENCODING' when embedding python.
New submission from Campbell Barton:
note, I was asked to report this issue, posted on the py dev mailing list: see
- http://code.activestate.com/lists/python-dev/118015/
---
We've run into an issue recently with blender3d on ms-windows where we
want to enforce the encoding is UTF-8 with the embedded python
interpreter.
(the encoding defaults to cp437).
I naively thought setting the environment variable before calling
Py_Initialize() would work, but the way python DLL loads, it gets its
own environment variables that cant be modified directly [1].
eg, _putenv("PYTHONIOENCODING=utf-8:surrogateescape");
We had bug reports by windows users not able to export files because
the stdout errors on printing paths with unsupported encoding. [2],[3]
---
Of course we could distribute blender with a bat file launcher that
sets env variables, or ask the user to set their env variable - but I
dont think this is really a good option.
I tried overriding the stderr & stdout, but this caused another bug on exiting,
giving an assert in MSVCR90.DLL's write.c (called from python32_d.dll):
_VALIDATE_CLEAR_OSSERR_RETURN((_osfile(fh) & FOPEN), EBADF, -1);
import sys, io
sys.__stdout__ = sys.stdout =
io.TextIOWrapper(io.open(sys.stdout.fileno(), "wb", -1),
encoding='utf-8', errors='surrogateescape', newline="\n",
line_buffering=True)
sys.__stderr__ = sys.stderr =
io.TextIOWrapper(io.open(sys.stderr.fileno(), "wb", -1),
encoding='utf-8', errors='surrogateescape', newline="\n",
line_buffering=True)
IMHO either of these solutions would be fine.
* have a PyOS_PutEnv() function, gettext has gettext_putenv() to
workaround this problem.
* manage this the same as Py_GetPythonHome(), which can be defined by
the embedding application to override the default.

[issue15859] PyUnicode_EncodeFSDefault win32 inconsistancy.
New submission from Campbell Barton:
There is an inconsistency in PyUnicode_EncodeFSDefault(), on Linux its argument
is checked to be unicode, and NULL is returned when its not. On windows
however, this throws an assertion.
The problem with this is, in some CAPI code you may pass an argument and check
for NULL as an error case, and allow the python API's exception to be exposed
to the script author.
The problem here is a linux developer can use PyUnicode_EncodeFSDefault() this
way, but not a windows developer.
A simplified use case below of a case where PyUnicode_EncodeFSDefault would
fail.
Attached a fix so windows and posix systems behave the same.
---
const char *PyC_UnicodeAsByte(PyObject *py_str, PyObject **coerce)
{
if (PyBytes_Check(py_str)) {
return PyBytes_AS_STRING(py_str);
}
else if ((*coerce = PyUnicode_EncodeFSDefault(py_str))) {
return PyBytes_AS_STRING(*coerce);
}

found.

Since blender projects need to be portable - compress entire projects and run on different systems, we cant ensure the native fs encoding is used. So surrogateescape seems to work very well, except for this one case I've run into, windows only. -- ___ Python tracker <http://bugs.python.org/issue10600> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue9713] Py_CompileString fails on non decode-able paths.
New submission from Campbell Barton :
On linux I have a path which python reads as...
/data/test/num\udce9ro_bad/untitled.blend
os.listdir("/data/test/") returns this ['num\udce9ro_bad']
But the same path cant be given to the C api's Py_CompileString
Where fn is '/data/test/num\udce9ro_bad/untitled.blend/test.py'
Py_CompileString(buf, fn, Py_file_input);
...gives this error.
UnicodeDecodeError: 'utf8' codec can't decode bytes in position 14-16: invalid

[issue9499] Python C/API Execution namespace undocumented. (patch included)
New submission from Campbell Barton : Some parts of the python api expect __main__ module dictionary to be the namespace when executing a script, this is true when running a python script from the python binary but NOT true when running a compiled script from the C/API which can lead to bugs which are not easy to solve unless the C/API author knows this. -- assignee: d...@python components: Documentation files: doc_py3_main_mod.diff keywords: patch messages: 112706 nosy: d...@python, ideasman42 priority: normal severity: normal status: open title: Python C/API Execution namespace undocumented.

[issue6913] Py_SetPythonHome incorrectly documented py3.x (rev 74792)
New submission from Campbell Barton :
Py_SetPythonHome takes a *wchar_t not a *char, this is obvious from
looking at the header,
However I tried using this function and couldn't get it working until I
made the home variable a static string.
when looking at the source this is obvious, but should be documented...
void
Py_SetPythonHome(wchar_t *home)
{
default_home = home;

[issue6616] PyList_APPEND (append without incref)
Campbell Barton added the comment: Hi Raymond, in general I agree with your comments that adding 2 ways to do things is not great. The reason I still think this is an advantage is that I know the API well enough (with manipulating dicts/lists etc) and I still want this function for the sake of convenience. For the same reason that PyList_SET_ITEM is useful, this is useful too. Loosing the error checking is a disadvantage but in many cases API's dont do error checking for every new item allocated. Python's own code does this in a few cases with PyList_SET_ITEM... eg. ./Python/_warnings.c:857: PyList_SET_ITEM(filters, 1, create_filter(PyExc_ImportWarning, "ignore")) ./Python/Python-ast.c:2757: PyList_SET_ITEM(value, i, ast2obj_cmpop((cmpop_ty)asdl_seq_GET(o->v.Compare.ops, i))); -- ___ Python tracker <http://bugs.python.org/issue6616> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue6616] PyList_APPEND (append without incref)
New submission from Campbell Barton : This patch was made on python r74276 Often when writing in C/Python I want to append to a list within a C loop of an unknown length. When this is done for newly created PyObject (which is quite common) - you need to assign each item to a variable and then decref it. eg: PyObject *item= PyFloat_FromDouble(x); PyList_Append(list, item); Py_DECREF(item); I have seen people make mistakes with this (in pygame code and blender3d), and run PyList_Append(list, PyFloat_FromDouble(x)), ofcourse this is not the fault of python/c api that devs do not read docs properly but I think it would be very convenient to have an append that works in a similar way to PyList_SET_ITEM This simple patch allows...
