[issue18054] Add more exception related assertions to unittest

[Nick Coghlan]

Nick Coghlan added the comment:

I think something like "assertThat" could address the problem nicely. Probably 
best to propose it as a separate issue, then we can make this one depend on 
that one if we decide to go that way.

[issue18171] os.path.expanduser does not use the system encoding

[Pascal Garcia]

New submission from Pascal Garcia:

The name of the user contains accents under windows.

This error occurs when using the function. expaduser("~")

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe9 in position 10: 
ordinal not in range(128)

ascii is the default encoding as sys.getdefaultencoding()
If in site.py "I enable Enable the support locale" then de defaultencoding 
become cp1252 and the function works.

Expand user should use the encoding used by the system (may be 
locale.getdefaultlocale()) to decode path given by the system instead of the 
default encoding the should be the target encoding.

I do beleave some other functions may be concerned by this problem.
I detect the problem on Windows (WP and 7), but I do beleave the problem may 
happen on Linux also.

[issue18172] New easter egg: insecure string pickle

[flying sheep]

New submission from flying sheep:

the second meaning of the error message “insecure string pickle” inspired at 
least two different people independently of drawing it.

i’d wish for a link to one of those pics in the docstring or message of the 
error.

thread: 
http://www.reddit.com/r/Python/comments/1fymy0/i_got_a_funny_error_trying_to_open_a_file_and/

we’d have to host the pic ourselves since imgur isn’t guaranteed to retain the 
picture (although that’d need many consecutive months of no one following the 
link)

[issue18106] There are unused variables in Lib/test/test_collections.py

[Vajrasky Kok]

Vajrasky Kok added the comment:

Fixed the test based on Ezio Melotti's advice.

However, Ezio did not comment specifically about whether we should cut or keep 
this line.

self.assertEqual(list(dup.items()), list(od.items()))

After studying the OrderedDict source code, I came to conclusion that if 
"self.assertEqual(dup, od)" is true, so is "self.assertEqual(list(dup.items()), 
list(od.items()))".

But if "self.assertEqual(dup, od)" is false, so is 
"self.assertEqual(list(dup.items()), list(od.items()))".

This is how OrderedDict tests the equality:

def __eq__(self, other):
if isinstance(other, OrderedDict):
return dict.__eq__(self, other) and all(map(_eq, self, other))
return dict.__eq__(self, other)

So I think it should be safe to remove:

self.assertEqual(list(dup.items()), list(od.items()))

[issue18173] Add MixedTypeKey to reprlib

[Nick Coghlan]

New submission from Nick Coghlan:

Armin Ronacher pointed out that one downside of the removal of implicit 
cross-type comparisons in Python 3 is that it makes it harder to produce a 
stable repr for mixed-type containers.

This seems like a valid point to me, so I propose adding a suitable 
"MixedTypeKey" definition to reprlib. Passing "key=reprlib.MixedTypeKey" would 
then reproduce the old Python 2. sorting behaviour.

We can actually improve on the Python 2 approach by basing the fallback 
comparison on fully qualified type names rather than on the type id.

Proposed implementation (see https://gist.github.com/ncoghlan/5743523):

>>> class MixedTypeKey:
... """Sort key for mixed type lists in Python 3
... 
... >>> sorted([None, ..., 1, 1j, "", (), {}, []])
... Traceback (most recent call last):
...   File "", line 1, in 
... TypeError: unorderable types: ellipsis() < NoneType()
... >>> sorted([None, ..., 1, 1j, "", (), {}, []], key=MixedTypeKey)
... [None, Ellipsis, 1, 1j, '', (), {}, []]
... """
... def __init__(self, k):
... self._sort_key = k
... self._type_name = self._get_fully_qualified_name(k)
... def _get_fully_qualified_name(self, k):
... k_type = type(k)
... # Use __qualname__ if available, __name__ otherwise
... try:
... k_name = k_type.__qualname__
... except AttributeError:
... k_name = k_type.__name__
... return k_type.__module__ + "." + k_name
... def __lt__(self, other):
... # Try standard sorting first
... sort_key = self._sort_key
... try:
... other_sort_key = other._sort_key
... except AttributeError:
... other_sort_key = other
... try:
... return sort_key < other_sort_key
... except TypeError:
... pass
... # If that fails, sort by the fully qualified type names
... try:
... other_type_name = other._type_name
... except AttributeError:
... other_type_name = self._get_fully_qualified_name(other)
... return self._type_name < other_type_name
... 
>>> sorted([None, ..., 1, 1j, "", (), {}, []])
Traceback (most recent call last):
  File "", line 1, in 
TypeError: unorderable types: ellipsis() < NoneType()
>>> sorted([None, ..., 1, 1j, "", (), {}, []], key=MixedTypeKey)
[None, 1j, {}, Ellipsis, 1, [], '', ()]
>>> MixedTypeKey(None) < ...
True

The stdlib version could omit the fallback to __name__ (since it doesn't need 
to cope with old versions of Python)

Support for other comparisons could theoretically be added, but I advise 
against it without a solid use case (sorting only needs __lt__).

[issue18171] os.path.expanduser does not use the system encoding

[Pascal Garcia]

Here are 2 logs one with the default site.py forcing defaultencoding to ascii, 
and the other to utf8.
You can see that the home dir includes accents : Pépé Not an insult to anybody 
but this stupid computer :)

When I force using the locale.getdefaultlocale() as encoding then the function 
works, but, after having called expanduser, I need to make an explicit 
decode(locale.getdefaultlocale()), or else the string can not be used to build 
path to files.

[issue14015] surrogateescape largely missing from documentation

[A.M. Kuchling]

A.M. Kuchling added the comment:

Here's a proposed patch that touches the Sphinx documentation and a docstring 
in codecs.py.  The text is slightly revised from my current revisions to the 
Unicode howto.

help(open) says "See the documentation for codecs.register for a list of the 
permitted encoding error strings".  This is strictly correct: the Sphinx 
documentation features this info.  But help(codecs.register) doesn't; it's more 
helpful to look at help(codecs.Codec).  

So maybe the docstring for open() should say: "See help(codecs.Codec) for a 
list of the permitted..." instead.

[issue18171] os.path.expanduser does not use the system encoding

[R. David Murray]

R. David Murray added the comment:

On linux as well this fails:

  os.path.expanduser(u'~' + os.sep)

But this works:

  os.path.expanduser('~' + os.sep)

Counterintuitive, to say the least.  The reason is that the value of the HOME 
environment variable is read as a byte string, but when that byte string value 
is added to the unicode u'~/', unicode coercion attempts to decode the byte 
string as an ASCII string, which fails.

So, you must manipulate paths as byte strings in python2, decoding them 
yourself with the appropriate codec if needed.

This stuff is handled automatically in Python3, using the default encoding as 
you suggest (plus the surrogateescape error handler to handle unknown bytes on 
linux/unix).  Fixes for stuff like this is a large part of the purpose of 
Python3.  

So, in Python2 this is working as expected.

[issue18171] os.path.expanduser does not use the system encoding

[Pascal Garcia]

Pascal Garcia added the comment:

Sorry for this error.
Thanks for the solution.

Here is the code as I modify it.
wrkdir= os.path.expanduser("~"+os.sep)
loc = locale.getdefaultlocale()
if loc[1]:
encoding = loc[1]
wrkdir= wrkdir.decode(encoding)

I need to explicitally decode the string if I want to use it and have the next 
sentence working a bit further.
os.path.join(wrkdir, u"Tango\\")

Encodding is a very good motivation to go to python3, and if i didn't have 
other constraints it would be done for ages.

For this special case I think that function should return strings with the 
default encoding, and the programmer should not have to know about the 
underground to make the right decode.

But it works, thanks again.
Pascal

[issue18174] Make regrtest with --huntrleaks check for fd leaks

New submission from Richard Oudkerk:

regrtest already tests for refcount leaks and memory allocation leaks.  It can 
also be made to check for file descriptor leaks (and perhaps also handles on 
Windows).

Running with the attached patch makes it look like test_openpty, test_shutil, 
test_subprocess, test_uuid all leak fds on Linux, but I have not investigated:

$ ./python -m test.regrtest -R 3:3 test_openpty test_shutil test_subprocess

[issue18138] ssl.SSLContext.add_cert()

[Christian Heimes]

Christian Heimes added the comment:

New patch:

* rename function to add_ca_cert()
* only accept CA certs, no other certs
* raise an error if extra data is found after cert (e.g. two certs). 
PEM_read_bio_X509() silently ignores extra data
* fixes from Ezio's code review
* documentation

[issue18022] Inconsistency between quopri.decodestring() and email.quoprimime.decode()

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

There are other inconsistencies. email.quoprimime.decode(), binascii.a2b_qp() 
and pure Python (by default binascii used) quopri.decodestring() returns 
different results for following data:

   quoprimime  binascii  quopri

 b'='  ''  b''   b'='
 b'==' '=' b'='  b'=='
 b'= ' ''  b'= ' b'= '
 b'= \n'   ''  b'= \n'   b''
 b'=\r'''  b''   b'=\r'
 b'==41'   '=A'b'=41'b'=A'

[issue18175] os.listdir(fd) leaks fd on error

[Richard Oudkerk]

New submission from Richard Oudkerk:

If os.listdir() is used with an fd, but fdopendir() fails (e.g. if the the fd 
is a normal file) then a duplicated fd is leaked.

This explains the leaks in test_shutil mentioned in #18174.

[issue18022] Inconsistency between quopri.decodestring() and email.quoprimime.decode()

[R. David Murray]

R. David Murray added the comment:

Most of the variations represent different invalid-input recovery choices.  I 
believe binascii's decoding of b'= \n' is incorrect, as is its decoding of 
b'==41'.  quopri's decoding of b'=\r' is arguably incorrect as well, given that 
python generally supports universal line ends.  Otherwise the decodings are all 
responses to erroneous input for which the behavior is not specified.

That said, we ought to pick one error recovery scheme and implement it in all 
places, and IMO it shouldn't be exactly any of the ones we've got.  Or better 
yet, use one common implementation.  Untangling quopri is on my (too large) 
List of Things To Do :)

[issue6632] Include more chars in the decimal codec

[Alexander Belopolsky]

Alexander Belopolsky added the comment:

I am changing the title slightly to include '\N{MINUS SIGN}' in the scope of 
this issues. See [1]:

"Unless anyone can point me to a case where \N{MINUS SIGN} should not be 
treated as a (duh) minus sign, we should go and try to make life easier for our 
users by adopting at least a few of such characters." (Łukasz Langa)

[issue18176] Builtins documentation refers to old version of UCD.

[Alexander Belopolsky]

New submission from Alexander Belopolsky:

Reference to 
http://www.unicode.org/Public/6.0.0/ucd/extracted/DerivedNumericType.txt in 
http://docs.python.org/3.4/library/stdtypes.html#numeric-types-int-float-complex
 should be changed to 
http://www.unicode.org/Public/6.1.0/ucd/extracted/DerivedNumericType.txt for 
3.3 and to 
http://www.unicode.org/Public/6.2.0/ucd/extracted/DerivedNumericType.txt for 
3.4.

Note that the change from 6.1 to 6.2 is immaterial because it did not involve 
the Nd category, but a change from 6.0 to 6.1 introduced several new ranges:

+110F0..110F9  ; Decimal # Nd  [10] SORA SOMPENG DIGIT ZERO..SORA SOMPENG DIGIT 
NINE
+11136..1113F  ; Decimal # Nd  [10] CHAKMA DIGIT ZERO..CHAKMA DIGIT NINE
+111D0..111D9  ; Decimal # Nd  [10] SHARADA DIGIT ZERO..SHARADA DIGIT NINE
+116C0..116C9  ; Decimal # Nd  [10] TAKRI DIGIT ZERO..TAKRI DIGIT NINE

[issue18170] define built-in exceptions in Python code

[Brett Cannon]

Brett Cannon added the comment:

Yeah, that's the tricky bit. =) That's why I was thinking of starting with the 
leaf exceptions and then just slowly working down the hierarchy until I hit 
exceptions that just had to exist in C code (e.g. BaseException, Exception, and 
maybe SyntaxError). The rest could be made fake with Exception to start and 
then replace after the module was loaded.

[issue6632] Include more chars in the decimal codec

[Alexander Belopolsky]

Alexander Belopolsky added the comment:

As a design principle, "accept what's unambiguous in any locale" is reasonable, 
but it is hard to apply consistently.  I would agree that the status quo is 
hard to defend.  After a long discussion, it has been accepted that fullwidth 
digits should be accepted and now float(u'１２３') is valid, but not 
float('＋１２３'), float('－１２３') or float('１２⒊'). The last example is

>>> '\N{FULLWIDTH DIGIT ONE}\N{FULLWIDTH DIGIT TWO}\N{DIGIT THREE FULL STOP}'
'１２⒊'

All these variations can be neatly addressed by applying NFKC or NFKD 
normalization to unicode data before conversion:

>>> float(unicodedata.normalize('NFKD', '＋１２３'))
123.0
>>> float(unicodedata.normalize('NFKD', '－１２３'))
-123.0
>>> float(unicodedata.normalize('NFKC', '１２⒊'))
123.0

This would even allow parsing fullwidth hexadecimal numbers:

>>> float.fromhex(unicodedata.normalize('NFKC', '０ｘ⒈７ｐ３'))
11.5
>>> int(unicodedata.normalize('NFKC', '７Ｆ'), 16)
127

but would not help with the MINUS SIGN.

Allowing '\N{MINUS SIGN}' is particularly attractive because arguably unicode 
text should prefer it to ambiguous '\N{HYPHEN-MINUS}', but on the same token 
fractions.Fraction() should accept '\N{FRACTION SLASH}' in addition to the 
legacy '\N{SOLIDUS}'.

Overall, I think this situation calls for a PEP-size proposal and discussion 
about handling unicode numerical data throughout stdlib rather that a case by 
case discussion of the various quirks in the curent version.

[issue18177] Typo in Documents

[icedream91]

New submission from icedream91:

In library.pdf file(Release 3.3.2, June 09, 2013), I found a typo in page 149: 
I think the quotation marks are wrong in "datetime.isoformat(sep=’T’)" 
sentence, they should both be "'".
But it's right in online documents 
(http://docs.python.org/3/library/datetime.html#datetime.datetime.isoformat).

Thanks.

[issue17899] os.listdir() leaks FDs if invoked on FD pointing to a non-directory

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

rewinddir() is called only when dirp != NULL && fd > -1. fdopendir() is called 
when fd != -1. close() is called when dirp == NULL && fd != -1. Therefore 
rewinddir() and fdopendir() with close() can't be called in the same time. And 
you can move block

if (dirp == NULL)
close(fd);

up, just after fdopendir(). In all other branches fd == -1 and close() is not 
called. You will save #ifdef HAVE_FDOPENDIR/#endif and 
Py_BEGIN_ALLOW_THREADS/Py_END_ALLOW_THREADS lines.

[issue18022] Inconsistency between quopri.decodestring() and email.quoprimime.decode()

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Perl's MIME::QuotedPrint produces same result as pure Python quopri. konwert 
qp-8bit produces same result as binascii (except '==41' it decodes as '=A').

RFC 2045 says:

"""A
  reasonable approach by a robust implementation might be
  to include the "=" character and the following
  character in the decoded data without any
  transformation and, if possible, indicate to the user
  that proper decoding was not possible at this point in
  the data.
