I've committed the patch with trivial fixes (adding curly braces to if 
statements).
And I'm sorry, I committed with wrong issue number.

[issue28391] Multiple occurances of: Closing quotes separate words

[R. David Murray]

R. David Murray added the comment:

Case 2 (the actual behavior) is correct.  Quotes *within* words are ignored, 
only a leading quoted string will result in a separate word.  (That's 
recursive: try '"Do""This""Separate).

That said, we don't really care about non-posix mode, it's just there for 
backward compatibility.  I don't know why we haven't changed the default for 
shlex.shlex to posix=True.

[issue28214] Improve exception reporting for problematic __set_name__ attributes

[Nick Coghlan]

Nick Coghlan added the comment:

Fixing the proposed format string accordingly, and also including the 
underlying exception type as I did in the examples:

f"Error calling __set_name__ on {type(the_attr).__name__!r} instance 
{the_attr_name!r} in {class_being_defined.__name__!r}: 
{type(raised_exc).__name__}: {str(raised_exc)}"

Slight change, as it makes sense to reference the special method name 
explicitly:

[issue28214] Improve exception reporting for problematic __set_name__ attributes

[Nick Coghlan]

Nick Coghlan added the comment:

The following seem like a reasonable starting point to me:

TypeError: Failed to set name on 'BadIdea' instance 'attr' in 'NotGoingToWork': 
'NoneType' object is not callable

TypeError: Failed to set name on 'FaultyImplementation' instance 'attr' in 
'TheoreticallyCouldWork': ZeroDivisionError: division by zero


That is, the error message format would be along the lines of:

f"Failed to set name on {type(the_attr).__name__!r} instance 
{the_attr_name!r} in {class_being_defined.__name__!r}: {str(raised_exc)}"

[issue21720] "TypeError: Item in ``from list'' not a string" message

[Nick Coghlan]

Nick Coghlan added the comment:

Berker's fix for Python 2.7 looks good to me.

However, Python 3 has a comparably vague error message, it's just inverted to 
complain about bytes rather than unicode due to the change in the native str 
type:

>>> __import__('encodings', fromlist=[b'aliases'])
Traceback (most recent call last):
  File "", line 1, in 
  File "", line 1013, in _handle_fromlist
TypeError: hasattr(): attribute name must be string

hasattr() in Python 2.7 is similarly unhelpful regarding what type it actually 
got when you give it something it doesn't expect.

[issue28391] Multiple occurances of: Closing quotes separate words

[Arno-Can Uestuensoez]

New submission from Arno-Can Uestuensoez:

I am currently writing an extended options scanner including 
shlex-compatibility mode. So including numerous extended unittests for 
compatibility verification.

I am not sure whether the following behaviour of shlex.split() is correct:

Quote from manual: 
  Parsing Rules: Closing quotes separate words ("Do"Separate is parsed as "Do" 
and Separate);

Case-0: Works
 sopts = """-a "Do"Separate """
 resx = ["-a", '"Do"', 'Separate', ]
 shlex.split(sopts,posix=False)
 assert res == resx 

Case-1: Fails - should work?
 sopts = """-a "Do"Separate"this" """
 resx = ["-a", '"Do"', 'Separate', '"this"', ]
 shlex.split(sopts,posix=False)
 assert res == resx 

Case-2: Works - should fail?
 sopts = """-a "Do"Separate"this" """ #@UnusedVariable
 resx = ["-a", '"Do"', 'Separate"this"', ]
 shlex.split(sopts,posix=False)
 assert res == resx 

The Case-0 is as defined in the manuals.

Is Case-1 or Case-2 the correct behaviour?
Which of Case-1, Case-2 is an error?

REMARK: I haven't found an eralier issue, so filing this here.

[Ned Deily]

Ned Deily added the comment:

Parvesh, we only maintain the latest micro release of a release cycle; for 2.7, 
that is currently 2.7.12.  In other words, once 2.7.9 was released, 2.7.8 was 
no longer supported by us (although, of course, downstream distributors of 
Cpython can choose to backport fixes to older releases on their own).

[issue28333] input() with Unicode prompt produces mojibake on Windows

[Steve Dower]

Steve Dower added the comment:

I made some minor tweaks to the patch (no need for strlen() - passing -1 works 
equivalently), but otherwise it's exactly what I would have done so I committed 
it.

We currently have no tests to check which characters are written to a console 
output buffer. Issue28217 was tracking those, but considering how little code 
we have on top of output I don't think it's worth blocking anything on 
automating those tests.

[issue15332] 2to3 should fix bad indentation (or warn about it)

[R. David Murray]

R. David Murray added the comment:

Agreed.  -tt is designed for this job; there's no need for 2to3 to duplicate 
the functionality given that reindent.py exists and can be (and "should" be) 
applied to the python2 source even if you aren't doing single-source.

[issue28376] rangeiter_new fails when creating a range of step 0

[Oren Milman]

Oren Milman added the comment:

Alright, just added 'with test.support.check_warnings(('', 
DeprecationWarning)):'.
*ver4.diff is attached.
I ran the tests again (this time using 'python_d.exe -We -m test -j3'), and 
they were successful :)

That was totally my bad, of course, but anyway, ISTM that 
https://docs.python.org/devguide/index.html should say './python -We -m test 
-j3' in section 4 (Run the tests).

[Oren Milman]

Oren Milman added the comment:

The diff files for 3.6 and 3.7 are attached (named '*ver3.diff').
Changes:
- in 3.6, added:
* raising a DeprecationWarning in rangeiter_new
* a test to verify the DeprecationWarning is raised
- in 3.7:
* changed the tests so they would only verify a TypeError is raised 
when calling either range_iterator or longrange_iterator
* removed the test.support.cpython_only decorator of the test

The output of 'python_d.exe -m test -j3' for each version is also attached 
(they were both successful).

[Attila Vangel]

Attila Vangel added the comment:

It's my pleasure.
It was somewhat similar:
- the set_proxy() is the same
- for the make_connection() I gave the necessary clues, so one can create the 
code and you can use that in a way that I don't have to spend time on the PSF 
Contributor Agreement
- overriding send_request() is not necessary at all, because the HTTP proxying 
is done in http.client level

[issue25720] Fix curses module compilation with ncurses6

[Masayuki Yamamoto]

Masayuki Yamamoto added the comment:

Added comment in review.

Yen,  I tried to build without curses.h file (overwrite to ncurses.h). It was 
failed on checking header. Hence, I confirmed curses headers on Cygwin and 
Ubuntu.

I found out that curses.h includes the directive "#include ". And 
unctrl.h has "#include ". Therefore, I think that some platforms 
require curses.h.
Would you confirm your platform curses library?

[issue28385] Bytes objects should reject all formatting codes with an error message

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Sorry, but it looks to me that issue28385.diff solves wrong issue. The issue is 
not in bytes, but in default __format__. object.__format__ should raise an 
error message that contains the name of the actual type. There are other issues 
with object.__format__, following patch tries to solve them.

1. Error message now contains the name of the actual type.

2. Format spec is checked before converting the value to str. Converting bytes 
and bytearray to str can raise a BytesWarning, and it is better if the type of 
this error doesn't depend on the -b option.

3. Since format spec is always empty, avoid calling PyObject_Format(). In 
theory PyObject_Str() can raise a subclass of str with non-trivial __format__, 
but I think we can ignore this subtle behavior difference.

[issue28385] Bytes objects should reject all formatting codes with an error message

[Eric V. Smith]

Eric V. Smith added the comment:

I left a comment on Rietveld, but repeating it here because for me those 
messages often go to spam:

I think you want to make this more general, by modifying the message for the 
TypeError that follows. Any type that doesn't provide it's own __format__ 
should produce an error when using a non-empty format string.

For example:

>>> format({}, 'a')
Traceback (most recent call last):
  File "", line 1, in 
TypeError: non-empty format string passed to object.__format__

Would be better as:
TypeError: non-empty format string passed to __format__ for object of type 
"class <'dict'>"

(Or some prettier way to print out the type).

[issue28389] xmlrpc.client HTTP proxy example code does not work

[Attila Vangel]

Attila Vangel added the comment:

Hi, thx for the quick turnaround.
I tried the proxy.py (on python 3.5) of course replacing 'YOUR_PROXY' with 
'10.144.1.11:8080' according to my environment.

python3 proxy.py 
Traceback (most recent call last):
  File "proxy.py", line 27, in 
print(server.examples.getStateName(41))
  File "/usr/lib/python3.5/xmlrpc/client.py", line 1092, in __call__
return self.__send(self.__name, args)
  File "/usr/lib/python3.5/xmlrpc/client.py", line 1432, in __request
verbose=self.__verbose
  File "/usr/lib/python3.5/xmlrpc/client.py", line 1134, in request
return self.single_request(host, handler, request_body, verbose)
  File "/usr/lib/python3.5/xmlrpc/client.py", line 1147, in single_request
resp = http_conn.getresponse()
  File "/usr/lib/python3.5/http/client.py", line 1197, in getresponse
response.begin()
  File "/usr/lib/python3.5/http/client.py", line 297, in begin
version, status, reason = self._read_status()
  File "/usr/lib/python3.5/http/client.py", line 258, in _read_status
line = str(self.fp.readline(_MAXLINE + 1), "iso-8859-1")
  File "/usr/lib/python3.5/socket.py", line 575, in readinto
return self._sock.recv_into(b)
ConnectionResetError: [Errno 104] Connection reset by peer


However, meanwhile I studied a bit the http.client API on how to use HTTP 
proxy, and I found set_tunnel() can do it. I had success by only overriding 
make_connection() in ProxiedTransport:
- copy current code of make_connection() from xmlrpc.client.Transport to 
ProxiedTransport (NOTE, this itself violates the DRY principle, but there is no 
better way to do it), change it slightly:
- create HTTPSConnection to the proxy (as I wanted to access a https URL)
- use .set_tunnel(chost) on this connection

I did not want to paste the code here, because
- I did not want to fill the 'PSF Contributor Agreement', at least yet
- it may be Python version specific solution.

[issue28389] xmlrpc.client HTTP proxy example code does not work

[Attila Vangel]

New submission from Attila Vangel:

Go to https://docs.python.org/3/library/xmlrpc.client.html
Under '21.26.8. Example of Client Usage' -> 'To access an XML-RPC 
server through a HTTP proxy, you need to define a custom transport. The 
following example shows how:' copy the example code to a .py file (for 
me it is easier than REPL), e.g. xmlrpc_client_http_proxy_test.py

This is the example code:

import xmlrpc.client, http.client

class ProxiedTransport(xmlrpc.client.Transport):
def set_proxy(self, proxy):
self.proxy = proxy

def make_connection(self, host):
self.realhost = host
h = http.client.HTTPConnection(self.proxy)
return h

def send_request(self, connection, handler, request_body, debug):
connection.putrequest("POST", 'http://%s%s' % (self.realhost, handler))

def send_host(self, connection, host):
connection.putheader('Host', self.realhost)

p = ProxiedTransport()
p.set_proxy('proxy-server:8080')
server = xmlrpc.client.ServerProxy('http://time.xmlrpc.com/RPC2', transport=p)
print(server.currentTime.getCurrentTime())


I changed the 'proxy-server:8080' to '10.144.1.11:8080' which is a 
valid HTTP/HTTPS proxy in company I work for.

Try to run this code:

$ python3 xmlrpc_client_http_proxy_test.py 
Traceback (most recent call last):
  File "xmlrpc_client_http_proxy_test.py", line 21, in 
print(server.currentTime.getCurrentTime())
  File "/usr/lib/python3.5/xmlrpc/client.py", line 1092, in __call__
return self.__send(self.__name, args)
  File "/usr/lib/python3.5/xmlrpc/client.py", line 1432, in __request
verbose=self.__verbose
  File "/usr/lib/python3.5/xmlrpc/client.py", line 1134, in request
return self.single_request(host, handler, request_body, verbose)
  File "/usr/lib/python3.5/xmlrpc/client.py", line 1146, in single_request
http_conn = self.send_request(host, handler, request_body, verbose)
  File "xmlrpc_client_http_proxy_test.py", line 13, in send_request
connection.putrequest("POST", 'http://%s%s' % (self.realhost, handler))
AttributeError: 'str' object has no attribute 'putrequest'

Personally I don't like the idea of putting this amount of code to 
documentation:
- as it seems, without automated tests running it, the code seems to rot, and 
gets outdated
- I need to paste this boilerplate code to my application if I want 
this functionality.

IMHO it would be much better to move this ProxiedTransport example code 
(after fixing it) to e.g. xmlrpc.client.HttpProxyTransport
(or similar name) class.

[issue26906] Special method lookup fails on unitialized types

[Oren Milman]

Oren Milman added the comment:

(Just to save time for anyone interested)
The last demonstration of the bug Serhiy mentioned is caused by the following 
(this was right only until Serhiy's patch earlier today):
- before importing collections.abc, str_iterator is not initialized, which 
means:
* Its tp_mro is NULL.
* _PyType_Lookup returns NULL (when called to lookup __length_hint__ in 
str_iterator (as part of operator.length_hint))
- on import, collections.abc also does 'Iterator.register(str_iterator)', 
which leads to the following call chain: ABCMeta.register(Iterator, 
str_iterator) => issubclass(str_iterator, Iterator) => 
PyObject_IsSubclass(str_iterator, Iterator) => 
Iterator.__subclasscheck__(Iterator, str_iterator) => 
Iterator.__subclasshook__(str_iterator) => 
collections.abc._check_methods(str_iterator, '__iter__', '__next__')
And _check_methods first does 'mro = C.__mro__', which ultimately calls 
type_getattro (which calls PyType_Ready in case tp_dict is NULL).


Anyway, with regard to the disconcerting comment:
/* If mro is NULL, the type is either not yet initialized
   by PyType_Ready(), or already cleared by type_clear().
   Either way the safest thing to do is to return NULL. */
Sorry for the newbie question, but why not add a Py_TPFLAGS_CLEARED flag to 
tp_flags?
Then we could assert in _PyType_Lookup (and maybe also in other places that 
call PyType_Ready, such as type_getattro) that the Py_TPFLAGS_CLEARED is not 
set..

I realize adding such a flag is really a big deal, but maybe it's worth 
catching sneaky bugs caused by Python's equivalent of Use-After-Free bugs?

Hmm, tests are passed on some Windows buildbots, but failed on others.

The error message is not very informative. Seems like some C API function takes 
an argument of wrong type (e.g. bytes instead of unicode).
