[Karthikeyan Singaravelan]

They are warnings related to third party packages used for doctest and some of 
them might become incompatible with

[issue25155] Windows: datetime.datetime.now() raises an OverflowError for date after year 2038

Hi,

"""
This bug is happening for 3.6 too.  Please see below,
(...)
  File 
"/home/dtdev/virtual/upwork/lib/python3.6/site-packages/pip/_vendor/requests/packages/urllib3/util/connection.py",
 line 85, in create_connection
sock.settimeout(timeout)
OverflowError: timestamp too large to convert to C _PyTime_t
"""

This error is different: the error occurs on socket.socket.settimeout() and 
comes from urllib3, not from the Python standard library. You should report 
this traceback to urllib3.

[issue35294] Race condition involving SocketServer.TCPServer

[Ruslan Dautkhanov]

New submission from Ruslan Dautkhanov :

We had a long discussion in https://issues.apache.org/jira/browse/SPARK-26019
regarding a race condition that happens 
around 
https://github.com/apache/spark/blob/master/python/pyspark/accumulators.py#L289 

The fix I created here -
https://github.com/apache/spark/pull/23113/files
basically changes bind_and_activate to False 
in SocketServer.TCPServer.__init__'s call 
and manually doing 
self.server_bind()
self.server_activate()
self.serve_forever()
in that thread instead of main thread. 

We have a fix, but we're not sure if this is a bug in Python with 
multithreading / handling SocketServer.TCPServer ?

Thank you.

[issue20309] Not all method descriptors are callable

[Simon Ruggier]

Simon Ruggier  added the comment:

I hit this problem today with what I'd consider a valid use case: I wanted to 
use a static method as a default argument to a function on the same class. 
Within the class definition context, automatic unwrapping of the staticmethod 
object doesn't occur, so the default value ends up not being callable unless 
the staticmethod object is manually, explicitly unwrapped via __func__.

For those who prefer code to prose, I've attached example Python 2/3 code 
demonstrating what I mean.

The workaround is pretty easy, but on the other hand, it also looks like it 
would also be pretty straightforward to facilitate this use case without 
forcing the author to learn about this distinction and manually unwrap the 
static method, and I think it makes sense to do that.

[issue24746] doctest 'fancy diff' formats incorrectly strip trailing whitespace

[Tim Peters]

Tim Peters  added the comment:

To include trailing whitespace on a line in a doctest, _don't_ use raw strings. 
 Use a regular string, and include add a (one or more) trailing \x20 instead of 
a space (for example).  For example:

r"""
>>> print("a ")
a 
"""

where there's a space at the end of the output line is no good.  It's visually 
impossible to tell what's intended, and the commit hook should reject it.  But 
this works fine (a regular string and an escape code):

"""
>>> print("a ")
a\x20
"""

[issue35283] "threading._DummyThread" redefines "is_alive" but forgets "isAlive"

[Dieter Maurer]

Dieter Maurer  added the comment:

> Care to open a PR to fix this?

I am not familiar with the "github" workflow. The fix is so trivial (add the 
"isAlive = is_alive" alias to "threading._DummyThread" and replace "isAlive" by 
"is_alive" in the docstring of "threading.Thread.join" that it does not seem 
worth to learn the "github" workflow just for this fix.

[issue35292] Make SimpleHTTPRequestHandler load mimetypes lazily

[Steve Dower]

New submission from Steve Dower :

Importing http.server triggers mimetypes.init(), which can be fairly expensive 
on Windows (and potentially other platforms?) due to having to enumerate a lot 
of registry keys.

Instead, SimpleHTTPRequestHandler.extensions_map can be a dict with just its 
default values in lib/http/server.py and the first call to guess_type() can 
initialize mimetypes if necessary.

We should check whether people read from 
SimpleHTTPRequestHandler.extensions_map directly before calling guess_type(), 
and decide how quickly we can make the change. My gut feeling is we will be 
okay to make this in the next release but probably shouldn't backport it.

[issue35291] duplicate of memoryview from io.BufferedWriter leaks

[Jason Madden]

New submission from Jason Madden :

Using Python 2.7.15, if a BufferedWriter wraps an IO object that duplicates the 
memoryview passed to the IO object's `write` method, that memoryview leaks. 

This script demonstrates the problem by leaking a memoryview for each iteration 
of the loop (if the `flush` is skipped, the leaks are less frequent but still 
occur):

```
from __future__ import print_function

import io
import gc

def count_memoryview():
result = 0
for x in gc.get_objects():
if type(x) is memoryview:
result += 1
return result

class FileLike(object):
closed = False

def writable(self):
return True

def write(self, data):
memoryview(data) # XXX: This causes the problem
return len(data)


bf = io.BufferedWriter(FileLike())

i = 0
memoryview_count = 0

while True:
if i == 0 or i % 100 == 0:
# This reports 100 new memoryview objects each time
old = memoryview_count
new = count_memoryview()
print(i, "memoryview", new, "+%s" % (new - old))
memoryview_count = new

bf.write(b"test")
bf.flush()
i += 1
```

The leak can also be observed using the operating system's memory monitoring 
tools for the process (seen on both Fedora and macOS).

Commenting out the line in `FileLike.write` that makes a duplicate memoryview 
of the given buffer solves the leak. 

Deleting the BufferedWriter doesn't appear to reclaim the leaked memoryviews.

I can't duplicate this in Python 3.4 or above.

Originally reported to gevent in https://github.com/gevent/gevent/issues/1318

Possibly related to Issue 26720 and Issue 15994

That's why I mentioned addfile() -- it takes TarInfo object for that purpose.  
I suppose the new function should have the same parameters, except it would set 
size in the TarInfo instance instead of getting it.

[issue35242] multiprocessing.Queue in an inconsistent state and a traceback silently suppressed if put an unpickable object and process's target function is finished

[Sergei Zobov]

Sergei Zobov  added the comment:

Thanks for answer, Antoine!
I see what you mean, but I'm not sure that it's so extreme corner case. We are 
speaking about Python and it's easy to create an put an unpickable object into 
queue.
I apologize for the persistence, but I just want make this case more friendly 
to user. I spent plenty of time to debug it and I think it would be better to 
prevent someone to do the same things.
If it's a difficult to fix, we can at least write a note somewhere in 
multiprocessing module doc to describe this behavior.

[issue31241] ast col_offset wrong for list comprehensions, generators and tuples

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

For list comprehensions and generator expressions this is definitely a bug. But 
tuples syntax technically does not include surrounded parentheses.

There is also a problem with generator expression passes as a single argument. 
Generator expression parentheses can be collapsed with function call 
parentheses: f(a for a in b).

PR 10633 makes the following changes:

* Fixes position for list comprehensions and generator expressions.

* If generator expression parentheses are be collapsed with function call 
parentheses, the position of the AST node for the generator expression points 
to the left parenthesis.

* For tuples surrounded with parentheses, the position of the AST node points 
to the left brace. For tuples without parentheses, it points to the position of 
the first tuple item.

I am not sure whether these changes should be backported to maintained versions.

[issue35242] multiprocessing.Queue in an inconsistent state and a traceback silently suppressed if put an unpickable object and process's target function is finished

[Antoine Pitrou]

Antoine Pitrou  added the comment:

Thanks for reporting this.  This sounds like an extreme corner case and I'm not 
sure how easy it will be to fix.

For the record, nowadays concurrent.futures should have more graceful behaviour 
in the face of errors.  Though there probably always will be corner cases like 
this.

[issue35200] Make the half-open range behaviour easier to teach

[Raymond Hettinger]

Raymond Hettinger  added the comment:

As a teacher, I think the proposal makes us worst off.  It is far easier and 
more useful at the interactive prompt to use list() rather than print() to show 
ranges:

>>> list(range(10))
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> list(range(2, 10))
[2, 3, 4, 5, 6, 7, 8, 9]
>>> list(range(2, 10, 3))
[2, 5, 8]

If you do the same thing with print(), it takes an additional character 
("print" vs "list"), it creates a new source of confusion (str vs repr), and it 
doesn't generalize to other iterators like enumerate(), reversed(), and 
generators.

Also, the various ideas listed for a possible new __str__ are all awkward or 
mysterious for some inputs (empty ranges, short ranges, etc).

FWIW, I teach this topic every week.  Presenting with list(range(...)) is less 
convenient than with the Python 2.7 version, but it works out just fine in 
practice and nicely sets the stage for covering set(iterable), tuple(iterable), 
dict.fromkeys(iterable), etc.

I'm opposed the this proposal because I think it will create more teaching 
difficulties than it solves.

Sorry, I forgot about this issue and independently made similar changes in 
issue34876. Please rebase your PR and determine whether it contains any useful 
changes in comparison with the current code (maybe new non-duplicated tests or 
useful refactoring?).
