[issue34788] ipaddress module fails on rfc4007 scoped IPv6 addresses

[Michal]

Michal  added the comment:

I would like to fix this problem if nobody is against that. I stumbled upon the 
very same thing recently and I think it would be a nice opportunity to 
contribute.

[issue13282] the table of contents in epub file is too long

[Ben Creasy]

Ben Creasy  added the comment:

Not sure if this is filed elsewhere, but the contents on the page at 
https://docs.python.org/3/contents.html could really use a collapse button, and 
could start automatically collapsed. The first half of the page is "What's new" 
for the past few Python versions and the Changelog.

I looked around for an issue in the upstream tracker and didn't see one 
https://github.com/sphinx-doc/sphinx/issues - I don't know much about Sphinx 
but it seems like it should be possible with a bit of Javascript and CSS.

[issue36580] unittest.mock does not understand dataclasses

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

Below is a even more simpler reproducer without dataclasses. 'name' is not 
listed as a class attribute in dir(Person) since it's not defined with a value 
but 'age' is with zero. Python seems to not to list something not defined with 
a value in declaration as a class attribute in dir().  Hence 'name' is not 
copied when Person is used as spec. spec only does attribute access validation. 
autospeccing [0] can be used for signature validation. The fields for 
dataclasses are defined in __dataclass_fields__ but I am not sure of special 
casing copying __dataclass_fields__ fields along with dir for dataclasses when 
normal Python doesn't list them as class attributes. If needed I would like 
dir(dataclass) to be changed to include __dataclass_fields__. I would propose 
closing as not a bug.

# ../backups/dataclass_dir.py

from unittest.mock import Mock

class Person:
name: str
age: int = 0

def foo(self):
pass

person_mock = Mock(spec=Person)
print(dir(Person))
print(dir(person_mock))
person_mock.foo
print("age" in dir(person_mock))
print("name" in dir(person_mock))

[issue36598] mock side_effect should be checked for iterable not callable

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

I am not sure if the snippets you are referring to are from testing-cabal/mock 
repo which could be different from master branch. Current code is at [0]

if effect is not None:
if _is_exception(effect):
raise effect
elif not _callable(effect):
result = next(effect)
if _is_exception(result):
raise result
else:
result = effect(*args, **kwargs)

if result is not DEFAULT:
return result

> This works correctly for iterables (such as lists) that are not defined as 
> generators.
However, if one defined a generator as a function this would not work.

This does seem to work for generator function as below. Sorry, maybe I am 
getting it wrong with respect to terminologies and understanding the issue. Can 
you add a short script around what you are expecting?

$ cat ../backups/bpo36598.py
from unittest.mock import patch

def gen(i):
while i < 5:
yield i
i += 1

def foo():
return 1

with patch('__main__.foo', side_effect=gen(0)):
for _ in range(2):
print(foo())
for _ in range(2):
print(foo())

The Python signal handler always runs in the main thread, but the signal can be 
caught by any thread. In other words, trip_signal() can be run by any thread.

You did not show travis build link which failed other than "obj dead or 
exiting" error.
Don't all other errors happened only on your environment?  If no, please link 
to travis build link.

As far as I can confirm now, only "obj dead or exiting" error is problem in 
Travis.

I suspect your environment (locale and venv used to run doctest), not your 
changes.

It is "obj dead or exiting" error.  I didn't say it is caused by your

It is only error happened in Travis.

namedtuple._asdict() changed to return dict instead of OrderedDict.
If your venv is created before the change, this error can be happened.

I didn't analyze why yet. I guess that they are not real memory leaks, but more 
minor issue in the code checking for memory leaks. Sadly, it seems like such 
small glitch can cause a whole Refleak buildbot worker to fail :-(

Right, but why did it start to fail since yesterday?


> You may run doctest with existing Python, not Python 3.8.

I used the command from the .travis.yml job: "... make -C Doc/ PYTHON=../python 
"...". It explicitly picks the Python it just compiled.

Why would we like to check the doctests using a random Python version, whereas 
it's Python 3.8 documentation?

Is it an error start to fail since yesterday?
As far as reading your first report, this is happen only in your local
environment.

This error is in your environment too.  Maybe you re-used old venv?

Because it "doctest".  Python behavior (repr) can be changed.
Python 3.8 replaces some OrderedDict usage with regular dict.

BTW, this started as a bug against coverage.py:

There are some more details there, including the fact that it must be a Python

Joshua Root  added the comment:

The follow-up fix (AC_CHECK_FUNC -> AC_CHECK_FUNCS) still needs to be

It seems it is caused by non English locale.

[issue36601] signals can be caught by any thread

[Jeroen Demeyer]

New submission from Jeroen Demeyer :

Because of some discussion that is happening on #1583 I noticed this bit of 
code in the OS-level signal handler (set by the C function sigaction() or 
signal()):

static void
signal_handler(int sig_num)
{
/* See NOTES section above */
if (getpid() == main_pid)
{
trip_signal(sig_num);
}

The check getpid() == main_pid is claimed to check for the main *thread* but in 
fact it's checking the process ID, which is the same for all threads. So as far 
as I can tell, this condition is always true.

This code essentially goes back to 1994 (commit bb4ba12242), so it may have 
been true at that time that threads were implemented as processes and that 
getpid() returned a different value for different threads.

Note that this code refers to receiving a signal from the OS. In Python, it's 
always handled (by the function registered by signal.signal) by the main 
thread. But the current behaviour actually makes sense, so we should just 
remove the superfluous check and fix the comments in the code.

"Object dead or exiting" is a less frequent random error with doctest. I am not

is overlooked in Travis since the next runs are fine.

[issue32308] Replace empty matches adjacent to a previous non-empty match in re.sub()

[Anders Hovmöller]

This was a really bad idea in my opinion. We just found this and we have no way 
to know how this will impact production. It's really absurd that 

re.sub('(.*)', r'foo', 'asd')

is "foo" in python 1 to 3.6 but 'foofoo' in python 3.7.

[issue36602] Recursive directory list with pathlib.Path.iterdir

[Laurie Opperman]

New submission from Laurie Opperman :

Currently, 'pathlib.Path.iterdir' can only list the contents of the instance 
directory. It is common to also want the contents of subdirectories recursively.

The proposal is for 'pathlib.Path.iterdir' to have an argument 'recursive' 
which when 'True' will cause 'iterdir' to yield contents of subdirectories 
recursively.

This would be trivial to implement as 'iterdir' can simply yield from 
subdirectories' 'iterdir'.

A decision would have to be made whether to continue to yield the 
subdirectories, or skip them. Another decision would be for whether each path 
should be resolved before checking if it is a directory to be recursed into.

[issue36593] Trace function interferes with MagicMock isinstance?

[Karthikeyan Singaravelan]

Karthikeyan Singaravelan  added the comment:

I think I got to this. See issue12370 (Use of super overwrites use of __class__ 
in class namespace) . msg138712 suggests a workaround to alias super at the 
module level. unittest.mock has the below line and NonCallableMock has 
__class__ defined as a property which is not set when set trace is used since 
the linked commit in 3.7.2 uses super() is somehow executed by settrace since 
it's in __delattr__ and not in a code path executed by user code?

Looking at the unittest.mock code super is not used anywhere but _safe_super is 
used which I hope is for this reason. So this is not a case with MagicMock only 
but rather a case with anything that inherits from NonCallableMock i.e. Mock, 
MagicMock etc. This is not a problem with import being made before the trace is 
set as you mentioned so set trace does something that exposes this issue

https://github.com/python/cpython/blob/536a35b3f14888999f1ffa5be7239d0c26b73d7a/Lib/unittest/mock.py#L48

# Workaround for issue #12370
# Without this, the __class__ properties wouldn't be set correctly
_safe_super = super

Sample program in issue12370. Add set trace SuperClass with using super() fails 
and passes without set trace for super(). Whereas SafeSuperClass that uses 
_safe_super (module level alias to super) passes both cases irrespective of 
usage of set trace. Nick coughlan added a message so that unittest.mock should 
use _safe_super in https://bugs.python.org/issue12370#msg161704

import sys

_safe_super = super

def trace(frame, event, arg):
return trace

if len(sys.argv) > 1:
sys.settrace(trace)

class SuperClass(object):

def __init__(self):
super().__init__()

@property
def __class__(self):
return int

class SafeSuperClass(object):

def __init__(self):
_safe_super(SafeSuperClass, self).__init__()

@property
def __class__(self):
return int

print(isinstance(SuperClass(), int))
print(isinstance(SafeSuperClass(), int))

➜  cpython git:(master) ✗ ./python.exe /tmp/buz.py
True
True
➜  cpython git:(master) ✗ ./python.exe /tmp/buz.py 1

There is a test for the above in Lib/test/test_super.py at 
https://github.com/python/cpython/blob/4c409beb4c360a73d054f37807d3daad58d1b567/Lib/test/test_super.py#L87

Add a trace as below in test_super.py at the top and the test case fails

import sys

def trace(frame, event, arg):
return trace

sys.settrace(trace)

The patch for this issue would be to use _safe_super instead of super() or to 
fallback to object() in the previous case that doesn't seemed to have suffered 
from this case. I can try to make a PR with tests. Added Michael for 
confirmation.

[issue16712] collections.abc.Sequence should not provide __reversed__

[Inada Naoki]

Inada Naoki  added the comment:

I close this issue because Reversible ABC was added.

It's sad that Sequnce.__reversed__ is just makes reversed() slow without any 
benefit.

But removing it without breaking backward compatibility is not easy for now.

[issue36604] Add recipe to itertools

[Bjorn Madsen]

New submission from Bjorn Madsen :

I would like to add a recipe to the itertools documentation (if it belongs 
there?)

The recipe presents a method to generate set(powerset([iterable])) in a 
fraction of the runtime. I thought others might find this method helpful and 
pushed it to github under MIT license.

The recipe is available with test here:

[issue18748] libgcc_s.so.1 must be installed for pthread_cancel to work

[STINNER Victor]

STINNER Victor  added the comment:

I looked at this old issue. First of all, "bug.py" filename is accurate: this 
program contains a bug, but it's non-obvious.

* the main thread opens a file which gets the file descriptor 3
* a new thread is spawns which indirectly closes this file descriptor on: 
sys.stdout.close()
* the main thread is not aware that the file has been closed, and so will try 
to close the same file descriptor 3 sometime during Python shutdown
* then, sometimes, the glibc fails with an internal error because the main 
thread closed a file descriptor which was just opened by the other thread to 
implement thread cancellation: that logs "libgcc_s.so.1 must be installed for 
pthread_cancel to work" and calls abort()

Note: the Python file object remains alive until the "t" local variable is 
cleared, since "t.fh" contains a strong reference to the file object.

Again: it's a bug in the program. "libgcc_s.so.1 must be installed for 
pthread_cancel to work" is just *one* example of bad thing that can happen.

What can be do on the Python side? Well, stop to ignore silently I/O errors 
when a file is closed by its destructor.

I wrote a shy PR 12786 to only log these exceptions in development mode (-X 
dev). I'm not sure if we could stop to silence these exceptions *by default*.

Python has been modified last years to first raise an exception on I/O errors 
when file.close() is called explicitly, and then a similar change has been done 
for call to socket.socket.close().

[issue13927] Document time.ctime format

[Cheryl Sabella]

Cheryl Sabella  added the comment:

I guess what I'm thinking of `Www Mmm dd hh:mm:ss ` as representing isn't 
so much a format, but rather a literal replacement of where each value has a 
placeholder in the string (that is, a pattern).  So, even if `Www` doesn't mean 
anything, to me it means that the first three characters in the string are a 
Weekday, then there's a space, then Mmm is the month, then a space, then dd is 
the day number (with zero sometimes suppressed), etc.  

If that is more confusing than not using it, then that's fine.  I just wanted 
to mention it.

Using %d to me is also confusing since the docs define %d as `Day of the month 
as a decimal number [01,31]`.  This clearly isn't using 01, but rather 
suppressing the 0.

[issue36603] should pty.openpty() set pty/tty inheritable?

[cagney]

New submission from cagney :

pty.openpty(), on systems with a working os.openpty() / openpty(3) executes:

if (openpty(_fd, _fd, NULL, NULL, NULL) != 0)
goto posix_error;
if (_Py_set_inheritable(master_fd, 0, NULL) < 0)
goto error;
if (_Py_set_inheritable(slave_fd, 0, NULL) < 0)
goto error;

where as on systems where this is fails it instead executes:

master_fd, slave_name = _open_terminal()
slave_fd = slave_open(slave_name)
i.e., result = os.open(tty_name, os.O_RDWR)
return master_fd, slave_fd

where os.open() was "Changed in version 3.4: The new file descriptor is now 
non-inheritable."

(personally I'd deprecate pty.openpty(), but that is just me)

[issue13927] Document time.ctime format

[Cheryl Sabella]

Cheryl Sabella  added the comment:

I would like to help get this issue merged as it's already been approved by a 
core developer.

Does anyone object to the change?  Victor made a suggestion on the PR for 
alternative wording and I wanted to give others a chance to comment on that.

Also, looking at the man page for asctime, they use `Www Mmm dd hh:mm:ss ` 
as the description of the output.  Maybe it would be helpful to add this since 
it shows the spacing and explicitly shows the day number taking up 2 characters?

Thanks!

[issue36604] Add recipe to itertools

[Raymond Hettinger]

Raymond Hettinger  added the comment:

Thank you for the suggestion and the nice work.

I'm going to decline adding this to our docs because it isn't in the spirit of 
the other recipes (reasonably common task, reasonably simple, and/or showing 
off effective combinations of the other itertools).

Though the docs aren't the right place for this, it would be nice if you 
published a blog post or some such to show off your work, detail the though 
processes, and illustrate how you measured performance).  Another option is to 
submit this to the more-itertools project.
