[issue23203] Aliasing import of sub-{module, package} from the package raises AttributeError on import.
New submission from Franck Michea:
Hi, for those of you that prefer to read an example, you can read that
commented demonstration of the bug[1].
Today I discovered what I think is a bug in the import system. Here is the
basic setup:
We have three nested packages: foo - bar - baz. The bar package imports
foo.bar.baz. We try to import foo.bar. This works well unless we try to alias
the foo.bar.baz import in foo.bar with the import ... as ... syntax. In that
case the file will be read and executed but when we get out of the import
statement, then python throws:
Traceback (most recent call last):
File string, line 1, in module
File foo_alias_mod/bar/__init__.py, line 1, in module
import foo_alias_mod.bar.baz as name_does_not_matter
AttributeError: 'module' object has no attribute 'bar'
This works whether baz is a package or a module actually. It does not matter if
it's from the interpreter, or in a file, ... I've seen it trigger with 2.7.5,
2.7.9, 3.4.5, tip, so I guess this has been here for some time.
Please read the link below for a complete demo, and you can always download the
tarball[2] to test yourself.

[issue20604] Missing invalid mode in error message of socket.makefile.

[issue12077] Harmonizing descriptor protocol documentation
Franck Michea added the comment: Here is at least a correction of Descriptors' HowTo. There are two versions since some stuff differs (object inheritance, ...). Here are some of my interrogations though: - RevealAccess is not using instance parameter, so value is shared. Is this intended? - Don't really know what to do with Function and Methods part. First I don't really understand the relevance of this in a descriptor how-to. Also it is know outdated in python3 version (unbound thing, ...), so what do? - In __getattribute__ function, I don't really understand the paramters given to __get__, why None and the instance? But this is probably my fault. This also doesn't answer the question about the real source that should be kept. What to do? I also need a proof-read, since english is not my first language... Anyway it's clearly not enough to be published like that Have a nice day! -- keywords: +patch nosy: +kushou versions: +Python 3.5 Added file: http://bugs.python.org/file29040/12077_descriptor_howto_python3.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12077 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17157] issubclass() should accept iterables in 2nd arg
Franck Michea added the comment: I am neutral on this too, it just felt odd and this is why the question raised. Yesterday I tried to add sequences and iterables (only to issubclass but indeed it would need better testing and all) and came to a problem with sequences. The current implementation authorizes (A, (B, (C, D))) (why?) so issubclass is recursive, but if we add sequences, they could create infinite recursions if seq[0] == seq (it's the case for strings for example, where 'a' is still a sequence and 'a'[0] == 'a'). So I don't know if it's really interesting. Anyone can use tuple() on an iterable to build its tuple value, though the value is built in memory. It basically just felt odd to take only tuples but I don't know. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17157 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue17151] Python 3 changement of behavior with __ne__: documentation not updated
New submission from Franck Michea: Hi. As of python 3, behavior of object.__ne__ changed to call (not object.__eq__) if implemented. This changement can be seen in function object_richcompare in file Objects/typeobject.c. Documentation didn't change though, still saying[1] that There are no implied relationships among the comparison operators. [...] Accordingly, when defining __eq__(), one should also define __ne__(). Maybe a paragraph about this new behavior would be fine? I am not sure if last sentence of last paragraph is what it means, but it was already there in python 2 doc so guess no. I am not sure about how to write it so no patch, sorry.

[issue16849] Element.{get, iter} doesn't handle keyword arguments when using _elementtree C accelerator.
New submission from Franck Michea:
Documentation:
-
http://docs.python.org/3.3/library/xml.etree.elementtree.html#xml.etree.ElementTree.Element.get
-
http://docs.python.org/3.3/library/xml.etree.elementtree.html#xml.etree.ElementTree.Element.iter
These two functions are documented with keyword arguments. Python
implementation works correctly, but as of 3.3, _etreeelement module in C is
hot-patching this module to enhance speed. C implementation only expects normal
arguments for get and iter. This is what this patch fixes.
First patch so:
- I am not sure about the key string in kwlist array, I followed code above
and it doesn't work without it, so I guess it's to for the normal arg.
- I am not sure about how to test iter with this. tag argument is never used.
- Included a test that shows the problem.
Have a nice day,
