[issue21598] Is __getitem__ and __len__ implementations enough to make a user-defined class sliceable?
New submission from Santoso Wijaya: The reference doc for Python data model says that __getslice__ is deprecated [1], and that __getitem__ should be used instead: Deprecated since version 2.0: Support slice objects as parameters to the __getitem__() method. (However, built-in types in CPython currently still implement __getslice__(). Therefore, you have to override it in derived classes when implementing slicing.) But I'm getting the following behavior when I try it myself.

[issue21403] cElementTree's Element creation handles attrib argument different from ET
Santoso Wijaya added the comment:
There is still a matter of inconsistency between the two implementations and
between 2.7 and 3.x. IMO, the Python-based ElementTree implementation is more
graceful at handling the attrib argument.
The signature of the factory function Element (and SubElement) in the doc is
thus:
class xml.etree.ElementTree.Element(tag, attrib={}, **extra)
which is fair game for the user to use attrib as a keyword argument.
Further, this serialization (in 3.x) does not really make sense, anyway:
cET.tostring(root)
b'root attrib={\'Name\': \'Root\'}child attrib={\'Name\': \'Child\'}
//root'

[issue21403] cElementTree's Element creation handles attrib argument different from ET
Santoso Wijaya added the comment:
Quoting dabrahams in issue 1572710:
On second thought, I see what effbot is trying to say... but it's still a bug.
Given the way the interface is declared and the behavior of regular python
functions:
Element(tag, attrib={}, **extra)
indicates that I can pass attrib (or tag, for that matter) as a keyword
argument. Nothing in the documentation gives the C implementation permission
to behave differently.

Besides, keeping the detection behaviour in light of this defect would be adding unnecessary complexity to the code. Currently, the `src` argument (=.\\test) is simply given to a Windows function to see if it is a directory, from the currently working directory. To make it aware of its path relativity, in the context of the target, is much harder than just changing the documentation. ;-) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13772 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I'd also like to point out that Unicode path is handled correctly in both 2.7.x
and 3.x:

The problem only lies in the code handling narrow string paths. If you look at
(py33) posixmodule.c:2545-6, the bare path is appended with L\\*.*. Whereas
in the narrow string case, posixmodule.c:2625-6, the bare path is appended with
/*.*, instead.
To be consistent, we should use '\\'.

[issue12340] Access violation when using the C version of the io module
Santoso Wijaya santoso.wij...@gmail.com added the comment: Regarding the crash, From what I can see, the `tp_clear` method of bufferedrwpair is called during Py_Finalize() that leads to garbage collection. This NULLs `self-writer` for the rwpair object. Later, in the same garbage collection routine, the `tp_clear` of textio (the wrapper) is called. This attempts to finalize its wrapped object by first calling the `closed` property of the wrapped object. This property read is propagated down to the wrapped bufferedrwpair, `bufferedrwpair_closed_get()`. At this point, `self-writer` for the bufferedrwpair object is already NULL from the previous clear. Hence, the crash happens because a NULL pointer dereferencing is attempted. -- nosy: +santa4nt ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12340 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12244] cStringIO inconsistencies
New submission from Santoso Wijaya santoso.wij...@gmail.com:
Observe:

win32
Type help, copyright, credits or license for more information.
from cStringIO import StringIO
result = StringIO('Hello, ')
result.write('world')
Traceback (most recent call last):
File stdin, line 1, in module
AttributeError: 'cStringIO.StringI' object has no attribute 'write'
result = StringIO()
result.write('Hello, world')
print result.getvalue()
Hello, world
from StringIO import StringIO
result = StringIO('Hello, ')
result.write('world')
print result.getvalue()
world,
Few things:
1. The error message says, StringI instead of StringIO.
2. Why does a cStringIO.StringIO object instantiated with a starter string not
have the `write` attribute?
3. Using the pure-Python equivalent, (2) succeeds but it overwrites the starter
string?
4. Regardless, (2) and (3) are not consistent with each other.
