[issue15439] Include Misc/ACKS names into the documentation
Martin v. Löwis mar...@v.loewis.de added the comment: I don't know how Doc ACKS is maintained, but I think the devguide is fine as it stands, whether or not Doc ACKS is preserved or not. People should put themselves into Misc/ACKS if they made a contribution, period. If people need to be acknowledged separately for contributing to the documentation, I think only major contributions (such as writing the documentation for a yet-undocumented module) should be explicitly acknowledged. I think this all started from the documentation having initially Guido van Rossum given as its sole author, and then later Fred Drake. So Doc/ACKS.txt may have been an attempt to correct the impression that these two are the authors, but I think it went into the wrong direction (eventually leading to the creation of issues such as this one) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15439 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15443] datetime module has no support for nanoseconds
Marc-Andre Lemburg m...@egenix.com added the comment: Vincenzo Ampolo wrote: Vincenzo Ampolo vincenzo.amp...@gmail.com added the comment: This is a real use case I'm working with that needs nanosecond precision and lead me in submitting this request: most OSes let users capture network packets (using tools like tcpdump or wireshark) and store them using file formats like pcap or pcap-ng. These formats include a timestamp for each of the captured packets, and this timestamp usually has nanosecond precision. The reason is that on gigabit and 10 gigabit networks the frame rate is so high that microsecond precision is not enough to tell two frames apart. pcap (and now pcap-ng) are extremely popular file formats, with millions of files stored around the world. Support for nanoseconds in datetime would make it possible to properly parse these files inside python to compute precise statistics, for example network delays or round trip times. Other case is in stock markets. In that field information is timed in nanoseconds and have the ability to easily deal with this kind of representation natively with datetime can make the standard module even more powerful. The company I work for is in the data networking field, and we use python extensively. Currently we rely on custom code to process timestamps, a nanosecond datetime would let us avoit that and use standard python datetime module. Thanks for the two use cases. You might want to look at mxDateTime and use that for your timestamps. It does provide full C double precision for the time part of a timestamp, which covers nanoseconds just fine. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15443 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15441] test_posixpath fails on Japanese edition of Windows
STINNER Victor victor.stin...@gmail.com added the comment: If a file name was invalid byte character, os.chdir() raises UnicodeDecodeError() instead of WindowsError. I realized that the problem is in the error handling: raising the OSError fails with a UnicodeDecodeError because PyErr_SetFromWindowsErrWithFilename() calls PyUnicode_DecodeFSDefault(), whereas the filename is not decodable. If you want to change something, it should be PyErr_SetFromWindowsErrWithFilename(). We may use PyObject_Repr() or PyObject_ASCII() for example. -- See also the issue #13374: The Windows bytes API has been deprecated in the os module.

I'm a bit surprised that we're not seeing compiler warnings about
this sort of thing.
The compiler has no chance to find out. You cast the pointer to
PyCFunction, telling the compiler that it really is a PyCFunction.
I really wish we could put a ban on function pointer casts, and try
to make this all statically type-correct. This, of course, would
require the sizeof function to take PyObject*, and cast it to
PyStructObject * locally. My idiom for that is
static PyObject *
s_sizeof(PyStructObject *_self, PyObject *unused)
{
PyStructObject *self = (PyStructObject *)_self;
It sounds like 'wrong everywhere' is accurate, unfortunately.
Everywhere is nowhere close to the truth. There are tons of
NOARGS functions which have the correct signature.

R. David Murray rdmur...@bitdance.com added the comment: @Anton: That's what I was guessing. If we had a unit test in test_webbrowser that did the same thing, we'd have seen the resource warning when running the tests and fixed it. However, it looks like there aren't *any* tests for webbrowser, not even in test_sundry (which just makes sure modules without tests are importable). So adding a test that will trigger this resource warning requires setting up a test_webbrowser file first, even before we get to the problem of how to test something that wants to start up a web browser...(but that should be solvable with unittest.mock, I think). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15447 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue12834] PyBuffer_ToContiguous() incorrect for non-contiguous arrays
Stefan Krah stefan-use...@bytereef.org added the comment: Here's a patch for 3.3, which consists mostly of tests. A couple of points: o I removed the len view-len check in PyBuffer_ToContiguous(), since the function is not documented and silently accepting output buffers that are too large seems unusual to me. o Removed the comment in bytesobject.c Better way to get to internal buffer?. IMO the answer is no: There isn't any better way that works in full generality. o Removed the need to check for overflow comment: ndim is now officially limited to 64. I think this can go into 3.3: It's easy to see that for contiguous buffers PyBuffer_ToContiguous() behaves in the same manner as before (except for the len issue). For memoryview, buffer_to_contiguous(x, y 'C') is literally the same code as buffer_to_c_contiguous(). -- keywords: +patch Added file: http://bugs.python.org/file26512/issue12834.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12834 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I would also recommend being systematic about this by creating a script to search the above files, along with a configuration section containing the list of replacements: e.g. correct spelling - list of misspellings for that name. And upload the script to this issue. That way people can see what misspellings have already been accounted for, more could be added easily, and it could be used again if necessary. Because this may grow in scope (e.g. into source files) and because it affects people's names, it may be worth raising on python-dev.

I don't think it's necessary to include the names in the doc. I don't know how Doc ACKS is maintained, but I think the devguide is fine as it stands, whether or not Doc ACKS is preserved or not. People should put themselves into Misc/ACKS if they made a contribution, period. In my experience Doc/ACKS.txt is mostly ignored/unmaintained. I did a lot of work on the docs and my name is not in there, and I don't think I ever added anyone there.

[issue15448] utimes() functions fail with ENOSYS even when detected by configure
New submission from Richard Moseley dickie.mose...@virgin.net: When building on a ASUS Eee PC 1000 running the original Xandros O/S with libc-2.7-13, the various utimes() functions are being detected as available for use, everything compiles. However, during installation of the lib-dynload libraries, the error 'Error: Function not implemented' is given and the installation halts. This problem has been tracked down to the fact that some of the utimes() functions will return ENOSYS rather than the expected result. I have now patched the configure.ac script to check for the seven variants of the function, which is attached. This patch would ideally have made use of the same model as the AC_CHCEK_FUNCS macro but this would require adding a new file to the source tree. -- components: Build files: configure.ac.diff keywords: patch messages: 166413 nosy: richmose priority: normal severity: normal status: open title: utimes() functions fail with ENOSYS even when detected by configure type: compile error versions: Python 3.3 Added file: http://bugs.python.org/file26514/configure.ac.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15448 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

As for the losing valuable debug information, much worse can be done:
import sys
try:
x
except NameError:
print('An error occurred.', file=sys.stderr)

This is obviously not how one should handle errors in development, but it's
allowed. As Ethan pointed out, the initial proposal can be recreated by just
adding three words which is obviously also allowed.
Nick, I'm not saying you're opinions are wrong, I just wanted to point out how
easy it is to throw away valuable information. It's almost futile.

Raymond Hettinger raymond.hettin...@gmail.com added the comment: This may be CPython specific. Also, sys.getsizeof() hasn't proved to be very useful (I never see anyone use it or see it in production code). Worse, it doesn't even make sense in the case of shared-key dictionaries and whatnot. Accordingly, there is little reason to make this more public than it already is.

Antoine Pitrou pit...@free.fr added the comment: sys.getsizeof() is not for production code, it's for experimenting and getting information at the command prompt. It's quite useful when you know its limitations.

[issue15441] test_posixpath fails on Japanese edition of Windows
STINNER Victor victor.stin...@gmail.com added the comment:
haypo: how is this meant to fix the bug?
Won't it now cause a WindowsError, when a successful
operation is expected?
Oh, I was referring to the new test proposed in the attached patch
(issue15441.patch):
+def test_chdir_invalid_filename(self):
+self.assertRaises(WindowsError, os.chdir, b'\xe7w\xf0')
os.chdir() in a non existent directory with a bytes name should raise an
OSError, not a UnicodeDecodeError.
--
About the original issue: it looks like mkdir(bytes) decodes internally the
directory name and ignore undecodable bytes. On Windows 7, mkdir(b\xe7w\xf0)
creates a directory called \u8f42 (b\xe7w, b\xf0 suffix has been
dropped). It is not possible to change the directory to b\xe7w\xf0, but it
works with b\xe7w or \u8f42.
There are 2 issues:
* On Windows, os.chdir(bytes) should not raise a UnicodeDecodeError on the
directory does not exist
* test_nonascii_abspath() can be skipped on Windows if
os.fsdecode(b\xe7w\xf0) fails, or b\xe7w name should be used instead
My patch is not the best solution because it looses information (if the
filename contains undecodable bytes). I realized that OSError.filename is not
necessary a str, bytes is also accepted. win32_error_object() can be used. The
following patch pass the original bytes object to OSError constructor instead:

[issue15450] Allow dircmp.subdirs to behave well under subclassing
New submission from Chris Jerdonek chris.jerdo...@gmail.com:
Currently, the subdirs attribute of filecmp.dircmp does not respect subclassing:
from filecmp import dircmp
class MyDirCmp(dircmp):
... pass
...
my_dcmp = MyDirCmp('dir1', 'dir2')
for item in my_dcmp.subdirs.values():
... print(type(item))
... break
...
class 'filecmp.dircmp'
This is the only place where dircmp does not respect subclassing. It can be
corrected here:
def phase4(self): # Find out differences between common subdirectories
...
...
self.subdirs[x] = dircmp(a_x, b_x, self.ignore, self.hide)
This would let one do things like override dircmp.report() and have
dircmp.report_full_closure() behave as expected.
