If someone would like to make a PR for using __qualname__ in error messages 
that would be great.  :)

[issue37521] importlib examples have their exec_module()/sys.modules assignment lines reversed

[Brett Cannon]

Brett Cannon  added the comment:

Nope, loader.exec_module() doesn't either: 
https://docs.python.org/3/library/importlib.html#importlib.abc.Loader.exec_module,
 
https://github.com/python/cpython/blob/master/Lib/importlib/_bootstrap_external.py#L776.

So unfortunately I'm still not sure what you're talking about.

[issue22121] Start IDLE from icon in a better place.

[Terry J. Reedy]

Terry J. Reedy  added the comment:

An implementation note mostly to myself: In 3.8 and before, 'python 
relative/path/to/file.py' results in the __file__ attribute of the main module 
being the relative path, and a possibly unnormalized full path is os.curdir + 
__file__.  I believe that this is the only situation in which __file__ is not 
absolute.  After os.chdir(new cwd), relative __file__ becomes useless unless 
the original curdir is saved or  __file__ is made absolute first.  The startup 
part of pyshell has this vulnerable line.
icondir = os.path.join(os.path.dirname(__file__), 'Icons')
But with curdir left alone when starting from a command line, there will be no 
problem.

"Changed in version 3.8: On macOS, the spawn start method is now the default. 
The fork start method should be considered unsafe as it can lead to crashes of

[issue37607] segfault running code in jupyter on macOS 10.14.5 - crashed on child side of fork pre-exec

[wesinator]

New submission from wesinator <13hu...@gmail.com>:

python 3.7.4 (homebrew) macOS 10.14.5
16 GB DDR4

segfault encountered when running test code in jupyter. 

Application Specific Information:
crashed on child side of fork pre-exec

I'm not in a position to share the code unfortunately, but I can say it was 
running multiple iterations of subprocess.Popen() within a multiprocessing Pool 
using os.cpu_count() / 2 number of processes (in this case 12/2 = 6).

Python test suite uses many external services:
https://pythondev.readthedocs.io/infra.html#services-used-by-unit-tests

You should all be skipped if the "network" resource is not used, which is the 
default.

Many tests were modified to catch network failures and ignore the test in this 
case. test_nntplib is known to be very fragile: it doesn't handle network 
issues.

I would suggest to remove functional tests which depend on external servers, 
since these tests fail often and nobody seems to care of test_nntplib.

[issue37605] CI should not depend on gmane response

[Terry J. Reedy]

New submission from Terry J. Reedy :

On Travis, 'Documentation tests' passing is apparently required.  Line 23 of 
nntplib.rst is ">>> s = NNTP('news.gmane.org')"  I use gmane and occasional 
failures to respond are routine.  Being able to merge should not depend on this 
external site.

In addition to a real failure, the following happen on PR 14675 earlier today.

https://travis-ci.org/python/cpython/jobs/559289634

Warning, treated as error:
**
File "library/nntplib.rst", line ?, in default
Failed example:
s = NNTP('news.gmane.org')
Exception raised:
Traceback (most recent call last):
  File "/home/travis/build/python/cpython/Lib/doctest.py", line 1328, in 
__run
exec(compile(example.source, filename, "single",
  File "", line 1, in 
s = NNTP('news.gmane.org')
  File "/home/travis/build/python/cpython/Lib/nntplib.py", line 1050, in

_getresp
raise NNTPTemporaryError(resp)
nntplib.NNTPTemporaryError: 400 load at 16.59, try later

Try later is what I do.  This exception should somehow be skipped.  I don't 
know anything about Travis and doctest tests and how flakey doctests are 
supposed to be handled. If nothing else, put the whole example is a try-except 
block?

>>> try:  # News sites can fail to respond.
... s = NNTP('news.gmane.org')
... ...
... except: # If site failure, try later.
... pass

Since output varies, I presume output checking is suppressed.

[issue37599] Remove a vague statement in documentation of Integer Objects

[Raymond Hettinger]

Raymond Hettinger  added the comment:

There's nothing wrong with a little wry humor in the docs, especially when the 
provide a little insight into the implementation.  It isn't irresponsible at 
all -- please avoid those pejoratives.

That said, I'll accept the patch because the sentence isn't necessary and has 
other issues (the statement makes more sense in the ctypes module where such 
changes are possible and it applies broadly to all immutable objects, not just 
pre-computed singleton integers).

this is issue #37561, making the sysconfigdata file name not changing with the 
kernel version of the OS.  I need to commit that patch to the trunk and 3.8.  
But apparently pip needs to be aware of that as well ...

Thomas Grainger  added the comment:

note that PEP 550 previously mentions catch_warnings as something that would 
benefit from some sort of Execution Context management

[issue34443] enum repr should use __qualname__

[Walter Dörwald]

Walter Dörwald  added the comment:

Can we at least get the __qualname__ in exception messages?

Currently enum.Enum.__new__() and enum.Enum._missing_() use:

   raise ValueError("%r is not a valid %s" % (value, cls.__name__))

IMHO this should be:

   raise ValueError("%r is not a valid %s" % (value, cls.__qualname__))

in both spots.

Example code:

class Person:
class Type(enum.Enum):
EMPLOYEE = "employee"
CUSTOMER = "customer"
SUPPLIER = "supplier"

class Contact:
class Type(enum.Enum):
EMAIL = "email"
PHONE = "phone"
MOBILE = "mobile"

with this the following code:

Person.Type('foo')

raises the exception:

ValueError: 'foo' is not a valid Type

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "", line 1, in 
  File 
"/usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/lib/python3.7/enum.py",
 line 310, in __call__
return cls.__new__(cls, value)
  File 
"/usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/lib/python3.7/enum.py",
 line 564, in __new__
raise exc
  File 
"/usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/lib/python3.7/enum.py",
 line 548, in __new__
result = cls._missing_(value)
  File 
"/usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/lib/python3.7/enum.py",
 line 577, in _missing_
raise ValueError("%r is not a valid %s" % (value, cls.__name__))
ValueError: 'foo' is not a valid Type

IMHO the exception message:

ValueError: 'foo' is not a valid Person.Type

would be much more helpful and unambiguous.

And BTW, maybe we should suppress exception chaining here, i.e. use:

   raise ValueError("%r is not a valid %s" % (value, cls.__qualname__)) from 
None

[issue37601] shutil.make_archive does not follow symlinks for zip archives

[issue37406] Disable runtime checks in release mode

[STINNER Victor]

STINNER Victor  added the comment:

I didn't find time to write a proper a rationale for this change, and I will 
not be available next weeks. So I prefer to close this issue. I may reopen it 
later once I have a strong rationale :-) In the meanwhile, have a look at the 
new PyHandle API idea which will start without sanity check in release mode 
since day 1 :-)

[Vinay Sajip]

Well, the statement about order isn't inaccurate when talking about Python in 
general and the cookbook is a resource meant to be useful across multiple 
Python implementations and versions, so I'd be inclined to leave it as is.

[issue37603] parsetok(): Assertion `(intptr_t)(int)(a - line_start) == (a - line_start)' failed, when running get-pip.py

[STINNER Victor]

New submission from STINNER Victor :

bpo-16806 introduced a regression with the following change:

commit 995d9b92979768125ced4da3a56f755bcdf80f6e (refs/bisect/bad)
Author: Anthony Sottile 
Date:   Sat Jan 12 20:05:13 2019 -0800

bpo-16806: Fix `lineno` and `col_offset` for multi-line string tokens 
(GH-10021)

get-pip.py does now crash:

$ ./python get-pip.py --help
python: Parser/parsetok.c:266: parsetok: Assertion `(intptr_t)(int)(a - 
line_start) == (a - line_start)' failed.
Aborted (core dumped)

Python 3.8 is also affected.

get-pip.py comes from: https://bootstrap.pypa.io/get-pip.py

Reproducing depends if REALLOC() returns a new pointer, see below.

I attached get-pip2.py: simplified version which crash when using "./python 
get-pip2.py --help". If it doesn't crash, duplicate lines to make the file 
larger.

--

The root issue seems to be that tok->multi_line_start isn't updated on 
REALLOC() in tok_nextc():

newbuf = (char *)PyMem_REALLOC(newbuf,
   newsize);
if (newbuf == NULL) {
tok->done = E_NOMEM;
tok->cur = tok->inp;
return EOF;
}
tok->buf = newbuf;
tok->cur = tok->buf + cur;
tok->line_start = tok->cur;

I guess that multi_line_start should also be updated there?

tok->multi_line_start = tok->cur;

[issue37584] Multiple test failures with OSError: [Errno 84] Invalid or incomplete multibyte or wide character on ZFS with utf8only=on

[STINNER Victor]

STINNER Victor  added the comment:

"""
On ext4 this creates 4 different files: ['\u03d4', '\u03d2\u0308', '\u03ab', 
'\u03a5\u0308']
On ZFS with utf8only=true (and I believe normalization=formD), only 2 files are 
created but each of the 4 filenames can be used to access either of the 2 files.
This is also the default behavior on Mac.

The test is already skipped on darwin 
(Lib/test/test_unicode_file_functions.py:120), and should be skipped for ZFS 
too (might depend on the exact flags used), however we weren't able to find a 
portable way to determine the filesystem and flags.
"""

I suggest to create a temporary directory, create the 4 files and see how many 
files you can using os.listdir(). If you get 4, the FS doesn't normalize 
anything. If you get less, it's likely that the FS normalizes names.

[issue37598] Don't use _ as a function name in logging documentation cookbook

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

Slightly unrelated to the issue but I noticed the below statement in the docs 
page couple of times. I think it's related to the order of kwargs when the 
statement was added in 3d9e972270270e1498712065a17ec3a589ae8986. Since order of 
kwargs is guaranteed from Python 3.6 can this be removed?
