[issue1635741] Py_Finalize() doesn't clear all Python objects at exit

Good Catch, Paulo.
IMHO, caches is useful in codecs(it's improve the search efficiency).

I have two humble idea:
1. Clean all item of codec_search_xxx in `Py_Finalize()`;
2. change the refcount mechanism(in this case, refcount+1 or refcount+2 make no 
differenct);

[issue40028] Math module method to find prime factors for non-negative int n

[Tim Peters]

Tim Peters  added the comment:

Jonathan, _almost_ no factoring algorithms have any use for a table of primes.  
Brute force trial division can use one, but that's about it.

A table of primes _is_ useful for implementing functions related to pi(x) = the 
number of primes <= x, and the bigger the table the better.  But that's not 
what this report is about.

Raymond, spinning up a process to factor a small integer is pretty wildly 
expensive and clumsy - even if you're on a box with gfactor.  This is the kind 
of frequently implemented thing where someone who knows what they're doing can 
easily whip up relatively simple Python code that's _far_ better than what most 
users come up with on their own.  For example, to judge from many stabs I've 
seen on StackOverflow, most users don't even realize that trial division can be 
stopped when the trial divisor exceeds the square root of what remains of the 
integer to be factored.

Trial division alone seems perfectly adequate for factoring 32-bit ints, even 
at Python speed, and even if it merely skips multiples of 2 and 3 (except, of 
course, for 2 and 3 themselves).

Pollard rho seems perfectly adequate for factoring 64-bit ints that _are_ 
composite (takes time roughly proportional to the square root of the smallest 
factor), but really needs to be backed by a fast "is it a prime?" test to avoid 
taking "seemingly forever" if fed a large prime.

To judge from the docs I could find, that's as far as gfactor goes too.  Doing 
that much in Python isn't a major project.  Arguing about the API would consume 
10x the effort ;-)

[issue37319] Deprecate using random.randrange() with non-integers

[Tim Peters]

Tim Peters  added the comment:

I have scant memory of working on this code.  But back then Python wasn't at 
all keen to enforce type checking in harmless contexts.  If, e.g., someone 
found it convenient to pass integers that happened to be in float format to 
randrange(), why not?  Going "tsk, tsk, tsk" won't help them get their work 
done ;-)

If we were restarting from scratch, I'd be happy enough to say "screw floats 
here - _and_ screw operator.index() - this function requires ints, period".  
But, as is, I see insufficient benefit to potentially making code that's been 
working fine for decades "deprecated".

Yes, I realize the code may eventually become marginally faster then.  That 
doesn't, to my eyes, outweigh the certainty of annoying some users.

[issue1635741] Py_Finalize() doesn't clear all Python objects at exit

[Paulo Henrique Silva]

Paulo Henrique Silva  added the comment:

About half of the remaining refs are related to encodings. I noticed that 
caches on Lib/encodings/__init__.py and codec_search_cach of PyInterpreterState 
are the places holding the refs. I removed those caches and number went do to:

Before: 4382 refs left
After : 2344 refs left (-46%)

The way to destroy codec_search_cache was recently changed on #36854 and $38962.

(Not proposing to merge this, but my changes are at 
https://github.com/python/cpython/compare/master...phsilva:remove-codec-caches).

[issue40045] Make "dunder" method documentation easier to locate

[Kyle Stanley]

New submission from Kyle Stanley :

In a recent python-ideas thread, the rule of dunder methods being reserved for 
Python internal usage only was brought up 
(https://mail.python.org/archives/list/python-id...@python.org/message/GMRPSSQW3SXNCP4WU7SYDINL67M2WLQI/),
 due to an author of a third party library using them without knowing better. 
Steven D'Aprano linked the following section of the docs that defines the rule: 
https://docs.python.org/3/reference/lexical_analysis.html#reserved-classes-of-identifiers.
 

When I had attempted to search for the rule in the documentation (prior to the 
above discussion), I noticed that it was rather difficult to discover because 
it was written just as "System-defined names" with no mention of "dunder" 
(which is what the dev community typically refers to them as, at least in more 
recent history).

To make it easier for the average user and library maintainer to locate this 
section, I propose changing the first line to one of the following:

1) System-defined names, also known as "dunder" names.
2) System-defined names, informally known as "dunder" names.

I'm personally in favor of (1), but I could also see a reasonable argument for 
(2). If we can decide on the wording, it would make for a good first-time PR to 
the CPython docs.

[SilentGhost]

SilentGhost  added the comment:

Leon, this most likely is not a bug, not because what's stated in 
documentation, but because you're most likely not testing what you think you 
do. Here is the test that you should be doing:

>>> re.match(r'(<)?(\w+@\w+(?:\.\w+)+)(?(1)>|$)', '>>

No match. If there is a different output in your setup, please provide both the 
output and the details of your system and Python installation.

[issue37319] Deprecate using random.randrange() with non-integers

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Using index() simplifies the code. Adding deprecation warnings complicates it. 
The PR consists of two commits, look at the first one to see how the code can 
finally look.

If you think that the deprecation is not needed, we can just keep the 
simplified version.

I'm generally against "fixing" things that aren't broken.  AFAICT, this has

working.  Tim, this is mostly your code, what do you think?

[issue40018] test_ssl fails with OpenSSL 1.1.1e

[Charalampos Stratakis]

Charalampos Stratakis  added the comment:

The relevant info which seems to make the tests fail:

Properly detect EOF while reading in libssl. Previously if we hit an EOF while 
reading in libssl then we would report an error back to the application 
(SSL_ERROR_SYSCALL) but errno would be 0. We now add an error to the stack 
(which means we instead return SSL_ERROR_SSL) and therefore give a hint as to 
what went wrong.

[issue40039] [CVE-2020-10796] Python multiprocessing Remote Code Execution vulnerability

[Junyu Zhang]

Junyu Zhang  added the comment:

Thank you for your reply, this report is indeed the situation prompted by the 
warning. There will be few problems in the single-machine deployment mode. Of 
course, it is also possible to take advantage of the possibility of elevation 
of privilege. In the distributed deployment mode, the client script is leaked. 
The resulting authkey leak will also cause RCE problems. I have an idea. If 
ManagerBase can allow users to customize the serialization operation, it may be 
greatly relieved. Your suggestion is that I need to submit this to 
secur...@python.org Report it?

[issue28180] Implementation of the PEP 538: coerce C locale to C.utf-8

[Nick Coghlan]

Nick Coghlan  added the comment:

The test cases for locale coercion *not* triggering still assume that 
bpo-19977, using surrogateescape on the standard streams in the POSIX locale, 
has been implemented (since that was implemented in Python 3.5).

Hence the various test cases complaining that they found "ascii:strict" (Py 3.4 
behaviour without bpo-19977) where they expected "ascii:surrogateescape" (the 
Py 3.5+ behaviour *with* bpo-19977).

To get a PEP 538 backport to work as intended on 3.4, you'd need to backport 
that earlier IO stream error handling change as well.

[issue39148] DatagramProtocol + IPv6 does not work with ProactorEventLoop

[Kjell Braden]

Kjell Braden  added the comment:

I tried some debugging with Python 3.9.0a4 and it looks like unparse_address in 
overlapped.c 
(https://github.com/python/cpython/blob/v3.9.0a4/Modules/overlapped.c#L689) 
raises the error. Almost seems like ENABLE_IPV6 is not set...

Encountered this bug on Python 3.7.6 (default, Jan  8 2020, 20:23:39) [MSC 
v.1916 64 bit (AMD64)], so on Windows 10. I can reproduce the bug with the code 
in message https://bugs.python.org/msg341149. 

It does not seem to be a duplicate of #29097 since I cannot reproduce that

In explain of action,

ENGLISH DOCUMENT: ..., 'append', ..., 'extend'

[issue40031] Python Configure IDLE 'Ok' and 'Apply' buttons do not seem to work.

[Saaheer Purav]

Saaheer Purav  added the comment:

I have tried everything like going to the .idlerc folder and making changes, 
but nothing worked. Finally, I had to change the original config files and it 
worked because Python is assuming that another theme which I put under 'IDLE 
Classic' is the original one. Also, the key for run-module(F5) doesn't work. In 
the original config file, the key for run-module is . However, Python 
does not read only that particular line and in the configure IDLE it shows that 
the field for run-module is empty.

[issue40040] ProactorEventLoop fails on recvfrom with IPv6 sockets

[Kjell Braden]

New submission from Kjell Braden :

on Windows 10 with Python 3.8.2 and Python 3.9.0a4, the ProactorEventLoop 
raises "OSError: [WinError 87] The parameter is incorrect" when recvfrom on an 
AF_INET6 socket returns data:


DEBUG:asyncio:Using proactor: IocpProactor
INFO:asyncio:Datagram endpoint local_addr=('::', 1) remote_addr=None 
created: (<_ProactorDatagramTransport fd=288>, <__main__.Prot object at 
0x028739A09580>)
ERROR:root:error_received
Traceback (most recent call last):
  File "...\Python\Python39\lib\asyncio\proactor_events.py", line 548, in 
_loop_reading

  File "...\Python\Python39\lib\asyncio\windows_events.py", line 496, in 
finish_recv
return ov.getresult()
OSError: [WinError 87] The parameter is incorrect


The same code works without issues on python 3.7 or when using 
WindowsSelectorEventLoopPolicy.

Karthikeyan Singaravelan  added the comment:

Thanks for the report. Is this a case of the warning below?

https://docs.python.org/3.8/library/multiprocessing.html#multiprocessing.connection.Connection.recv

> Warning The Connection.recv() method automatically unpickles the data it 
> receives, which can be a security risk unless you can trust the process which 
> sent the message.

> Therefore, unless the connection object was produced using Pipe() you should 
> only use the recv() and send() methods after performing some sort of 
> authentication. See Authentication keys.
