[issue7994] object.__format__ should reject format strings

[Eric Smith]

Eric Smith  added the comment:

Meador: Your patch (-3) looks identical to mine (-2), unless I'm making some 
mistake. Could you check? I'd like to get this applied in the next few days, 
before 2.7b1.

Thanks!

[issue8193] test_zlib fails with zlib 1.2.4

[Nick Coghlan]

Nick Coghlan  added the comment:

I'm not sure simply changing the value is the right thing to do - with older 
zlib versions (which do the wrong thing with 0), we definitely want that 
exception to be triggered.

For newer versions, we want to check that passing in 0 worked as specified in 
the zlib patch note and that -1 still raises the exception.

Changing the test behaviour based on zlib.ZLIB_VERSION is likely the best 
option.

Seems that from Python 2.6 to 3.2 the test work fine. With -1 still raises the 
exception. By the way, the original problem of Arkadiusz was with Python 2.5.

[issue8264] hasattr doensn't show private (double underscore) attributes exist

[Nick Craig-Wood]

New submission from Nick Craig-Wood :

I just spend a while tracking down a bug in my code which turned out to be an 
unexpected behaviour of hasattr.

Running this

class Test(object):
def __init__(self):
self.__private = "Hello"
def test(self):
print(self.__private)
print(hasattr(self, "__private"))
print(getattr(self, "__private"))


t = Test()
t.test()

Prints

>>> t.test()
Hello
False
Traceback (most recent call last):
  File "private_test.py", line 10, in 
t.test()
  File "private_test.py", line 7, in test
print(getattr(self, "__private"))
AttributeError: 'Test' object has no attribute '__private'
>>>

Indicating that even though we just printed self.__private hasattr() can't find 
it nor getattr().

I think this is probably the intended behaviour, but it does seem inconsistent.

Probably all that is required is a documentation patch...

Maybe something add something like this to the end of

  http://docs.python.org/library/functions.html#hasattr

Note that hasattr won't find private (double underscore) attributes unless the 
mangled name is used.

[issue8264] hasattr doensn't show private (double underscore) attributes exist

[R. David Murray]

R. David Murray  added the comment:

You are correct, this is the expected behavior.  Name mangling happens only at 
compilation time (see 
http://docs.python.org/reference/expressions.html#atom-identifiers).  A doc 
note for get/setattr would probably be useful.

(I removed 3.3; that version doesn't exist yet and should only be set on issues 
that can only be dealt with in 3.3, such as removing something deprecated in 
3.2.)

Fedora (see for example http://fedoraproject.org/wiki/Packaging/SourceURL )

[issue8240] ssl.SSLSocket.write may fail on non-blocking sockets

[Cyril]

Cyril  added the comment:

> Hmm, indeed. What you can do, very simply, is cache the getvalue()
> result once you have generated it.

After some thoughts, it's not really an option: my cStringIO.StringIO buffer 
is, well a buffer. To append data to the buffer, I call buffer.write(). When 
I've got a chance to send data over the socket (remember, it's async, so I 
don't really know when it's going to happen), I call buffer.getvalue().

If socket.write() returns zero byte written, I'll have to wait until I get 
another chance to send my buffer. But in the meantime, some more data might get 
appended to the buffer, and the string returned by getvalue() will be different 
from the first call (and thus, I can't really cache it).

I could find some tricks (like using multiple buffers), but it would be ugly.

[issue8269] Missing return values for PyUnicode C/API functions

[Arnaud Fontaine]

New submission from Arnaud Fontaine :

For example, PyUnicode_FromFormat() does not specify the return value but it 
does not seem to be only one. I only have a basic knowledge of Python C/API, so 
I am not sure whether it is meaningful.

[issue2521] ABC caches should use weak refs

[Antoine Pitrou]

Antoine Pitrou  added the comment:

Hmm, Benjamin pointed out that ABCs only support new-style classes, so 
old-style classes could be detected early instead of being added to the 
_abc_negative_cache.

[issue2521] ABC caches should use weak refs

[Antoine Pitrou]

Antoine Pitrou  added the comment:

By the way, Daniel, your patch doesn't look right.
First, you shouldn't need all the sortedlist/sortedset hierarchy.
Second, len(gc.get_objects()) is a truly horrible way of checking the classes 
have been destroyed. Just take a weakref to the class before deleting it, and 
check that calling the weakref returns None.
(besides, we also have a refleak-detection run (regrtest -R) which can detect 
leaks even if you don't check them explicitly in your tests)

[issue2521] ABC caches should use weak refs

[Daniel Stutzbach]

Daniel Stutzbach  added the comment:

Are you sure the old-style classes don't support ABCs?

ABCTestCase.validate_isinstance in Lib/test/test_collection.py specifically 
tests that both new-style and old-style classes work, unless I'm reading it 
wrong.

(and those tests fail if I make ABCMeta.__instancecheck__ and 
ABCMeta.__subclasscheck__ always return False for old-style classes)

In those cases, it's because __subclasscheck__ is overridden. You can't

[issue8270] Should socket.PF_PACKET be removed, in favor of socket.AF_PACKET?

[Denilson Figueiredo de Sá]

New submission from Denilson Figueiredo de Sá :

If you look at socket module, there are around 29 AF_* constants (like AF_INET).

On the other hand, there is only one PF_ constant: PF_PACKET. This constant is 
also defined as AF_PACKET.

Following the "There should be one-- and preferably only one --obvious way to 
do it." advice, Python 3 removed the <> operator.  I know it's a bit late to 
change things in Python 3, but should socket.PF_PACKET be removed, in favor of 
socket.AF_PACKET? (of course, before being removed, it would be left as 
deprecated for quite some time)

[issue2521] ABC caches should use weak refs

[Daniel Stutzbach]

Daniel Stutzbach  added the comment:

You can't register an old-style class, but many ABCs support duck-typing by 
implementing __subclasshook__.  ABCMeta caches those results and stores a 
reference to old-style classes, sometimes in _abc_cache and sometimes in 
_abc_negative_cache.  It can't simply return False.

I guess that leaves two options:

1) Make old-style classes weak-referenceable and cache the results of 
__subclasshook__.
2) Refuse to cache old-style classes and call __subclasshook__ every time for 
old-style classes.

Python 2.7a4+ (trunk:79493, Mar 30 2010, 19:19:13)
>>> class old_iterable_class:
...   def __iter__(self):
... pass

[issue1220212] os.kill on windows

[Brian Curtin]

Brian Curtin  added the comment:

Here is a patch with some tests and doc changes.

I'm having trouble coming up with tests which will work with CTRL_C_EVENT and 
CTRL_BREAK_EVENT. Based on my understanding of GenerateConsoleCtrlEvent, I 
figured this example 
(http://msdn.microsoft.com/en-us/library/ms685049%28v=VS.85%29.aspx) would be 
receptive to CTRL+C when started as a subprocess, but it doesn't work. I also 
figured "python -c "input()"" started as a subprocess could be killed with 
CTRL_C_EVENT, but it doesn't work either.

[issue8271] str.decode('utf8', 'replace') -- conformance with Unicode 5.2.0

[John Machin]

New submission from John Machin :

Unicode 5.2.0 chapter 3 (Conformance) has a new section (headed "Constraints on 
Conversion Processes) after requirement D93. Recent Pythons e.g. 3.1.2 don't 
comply. Using the Unicode example:

 >>> print(ascii(b"\xc2\x41\x42".decode('utf8', 'replace')))
 '\ufffdB'
 # should produce u'\ufffdAB'

Resynchronisation currently starts at a position derived by considering the 
length implied by the start byte:

 >>> print(ascii(b"\xf1ABCD".decode('utf8', 'replace')))
 '\ufffdD'
 # should produce u'\ufffdABCD'; resync should start from the *failing* byte.

Notes: This applies to the 'ignore' option as well as the 'replace' option. The 
Unicode discussion mentions "security exploits".

[issue8272] Odd exception messages when using cStringIO.StringIO instances as callables.

[workshed]

New submission from workshed :

Just a minor nit (or I'm missing something), but the results of trying to use a 
cStringIO.StringIO instance as a callable look wrong to me.  It should of 
course raise an exception, but shouldn't the 'cStringIO.StringO' and 
'cStringIO.StringI' strings reported in the errors below both read 
'cStringIO.StringIO'?

[issue8260] When I use codecs.open(...) and f.readline() follow up by f.read() return bad result

[Daniel Diniz]

Daniel Diniz  added the comment:

Hi Stephane,

I think you're seeing different buffering behavior, which I suspect is correct 
according to docs.

codecs.open should default to line buffering[1], while open uses the system 
default[2].

The read() where the assert fails is returning the remaining buffer from the 
readline (which read 72 chars).

Asserting e.g. "f.read(1024) == ..." will give you the expected result.

[issue8198] Importing pydoc and overwriting sys.stdout, causes one char to be sent to the console when calling help()

[Daniel Diniz]

Daniel Diniz  added the comment:

Nice buglet, please take a look at Lib/pydoc.py to follow :)

As you point out, this is issue 1700304.
 
'plainpager', which outputs the help in these cases, uses 
'sys.stdout.write(plain(text))', but Helper.help has a 
"self.output.write('\n')" line that causes the behavior you see.

We could change "self.output.write('\n')" to "pager('\n')", but the real bug is 
that self.output is bound early to sys.stdout. So 'help()' is still redirecting 
to the old sys.stdout with your test.

I see a solution by turning Helper.output into a property, but it smells of 
over-engineering :) Passing all output to pagers should work too, unless we 
need Helper.output as a sort of sys.stderr.

The patch below shows that importing pydoc sets self.output prematurely and 
includes the "self.output.write('\n')" line.
