[issue32884] Adding the ability for getpass to print asterisks when password is typed

[Andrei Kulakov]

Andrei Kulakov  added the comment:

Unfortunately modern laptop keyboards have almost no key travel and barely any 
tactile feedback [*]. Users on such keyboards really do need feedback for each 
key pressed. Not providing an option for such feedback is in effect forcing 
users to choose maximally weak password.

[*] worse, a large proportion of MBP keyboards produced in the last few years 
have the notoriously bad 'butterfly' key design that occasionally duplicates 
and swallows keypresses. Yes, a trillion dollar company can't make a functional 
keyboard.

[issue44877] Python > 3.7 build fails with IBM XL compiler

[Quellyn Snead]

New submission from Quellyn Snead :

Python 3.8 and above fails to build with the IBM XL compiler on Power9 
platforms.

## System and Environment Information

```
$ arch
ppc64le
```

```
$ echo $CC
xlc 
-F/projects/opt/ppc64le/ibm/xlc-16.1.1.7/xlC/16.1.1/etc/xlc.cfg.rhel.7.8.gcc.8.3.0.cuda.10.1
```

```
$ xlc --version
IBM XL C/C++ for Linux, V16.1.1 (5725-C73, 5765-J13)
Version: 16.01.0001.0007
```

## Test Procedure
```
$ git clone g...@github.com:quellyn/cpython.git
$ cd cpython
$ checkout 3.8

$ ./configure --with-pydebug
$ make -j2 | tee -a make.out
```

I tested for 3.7, 3.8, 3.9, 3.10, and master. In all cases the `make` failed 
for versions 3.8+. I've attached both the `config.log` and the make output logs 
for all. 

- Power9 architecture (ppc64le)
- IBM XL C/C++ 16.1.1.7

Python 3.7 builds without issue.

[issue44876] .replace functions in datetime do not call __new__

[Joel Gibson]

New submission from Joel Gibson :

I've come here while investigating a segfault when datetime.replace(...) was 
called with a Pandas Timestamp object:
https://github.com/pandas-dev/pandas/issues/42305

The Python implementation of datetime.replace
https://github.com/python/cpython/blob/03e5647ab07c7d2a05094fc3b5ed6eba6fc01349/Lib/datetime.py#L1823
is polymorphic, in the sense that if a custom object like pd.Timestamp is 
passed in, a pd.Timestamp will come out rather than a datetime. This works just 
fine (copying and using Python code makes this segfault disappear). 

The C implementation is also polymorphic
https://github.com/python/cpython/blob/03e5647ab07c7d2a05094fc3b5ed6eba6fc01349/Modules/_datetimemodule.c#L5845
but I think that something in the C implementation is wrong: eventually 
tp_alloc gets called for the passed type, but never tp_new, and then afterwards 
the custom type is treated just like a regular datetime. In the pd.Timestamp 
case, there are some extra fields that only get set in the __new__ method, 
leading to a segfault later when they're accessed.

I'm not familiar enough with the C/CPython interface (especially object setup 
and initialisation) to tell where a fix for this should go, I would assume that 
the line
https://github.com/python/cpython/blob/03e5647ab07c7d2a05094fc3b5ed6eba6fc01349/Modules/_datetimemodule.c#L5872
should be replaced by a call to PyObject_new(Py_TYPE(self), ...), or something 
similar.

This also affects date.replace and time.replace.

[issue44875] Update dis.findlinestarts documentaiton to reflect new usage of `co_lines` (PEP 626)

[George King]

New submission from George King :

`dis.findlinestarts()` has been changed to use the no `co_lines()` function. 
(Blame indicates commit 877df851c3e by Mark Shannon.) However the docs 
currently state that it uses the older `co_firstlineno` and `co_lnotab`: 
https://docs.python.org/3.10/library/dis.html#dis.findlinestarts.

My cursory understanding of `dis.py` internals is that `get_instructions` 
relies on `findlinestarts`, implying that both of these APIs are going to 
return different line numbers than they did previously. I am perfectly fine 
with this, and hopeful that the PEP 626 changes will improve tool accuracy.

At minimum the `dis` docs should be updated. I also suggest that some kind of 
note about this be added to the PEP 626 text, because the way it reads now 
suggests that it avoids breakage by creating the new `co_lines` API. However it 
seems that users of the higher level dis APIs are going to see subtly different 
behavior.

FWIW I am fine with the change, and I hope this doesn't instigate a reversion 
to the old behavior. `lnotabs` semantics were very cryptic and seemed rather 
broken when I attempted to use it years ago. I am revisiting an experimental 
code coverage tool in part because of the PEP.

[issue44874] Deprecate Py_TRASHCAN_SAFE_BEGIN/END

[Irit Katriel]

New submission from Irit Katriel :

The old trashcan macros - Py_TRASHCAN_SAFE_BEGIN/END are unsafe (see 
Issue40608).

They were removed from the limited C API in 3.9: 
https://github.com/python/cpython/blob/main/Doc/whatsnew/3.9.rst#removed-1

They should be removed altogether, in favour of Py_TRASHCAN_BEGIN/END. Since 
they are not documented, I think this would be done by changing the comment 
before their definition in Include/cpython/object.h.

... 
>>> e = MyError('e')
>>> e.__context__ = e
>>> 
>>> try:
...   raise e
... except MyError:
...   print('done')
... 
done  # hangs after this
^C^Z
```

[issue44873] base64 RFC4648 test cases

[Andrei Kulakov]

New submission from Andrei Kulakov :

RFC 4648 [1] has added a list of encoding test cases -- see section 10 of the 
RFC. It might be nice to add a test function that is a direct copy of these 
test cases. This will make conformance to this RFC clearer (actually right now 
we don't state conformance with 4648 in the docs except for b32 hex 
encode/decode, but I'm planning to update the docs in a separate issue).

This will also let us easily keep test cases in sync with future updates in the 
RFC.

The tests are similar to what we already have except our test cases go from '' 
=> 'abc', and their test cases from '' => 'foobar' (by adding a character at a 
time in succession). [also some of our test cases go from '' to 'abcde', so a 
bit inconsistent.]

I've confirmed that all of their test cases pass with Python dev branch code.

I can put up a PR if this sounds good.

[issue44854] Add .editorconfig to the root directory

[Łukasz Langa]

Łukasz Langa  added the comment:

> I did not see anything in the EditorConfig guide about what happens when 
> .editorconfig does not start with root = true and another file is found.

Good question. The docs do mention this but the information is scattered across 
the website. The key points are:

> EditorConfig files are read top to bottom and the most recent rules found 
> take precedence. Properties from matching EditorConfig sections are applied 
> in the order they were read, so properties in closer files take precedence.

> When opening a file, EditorConfig plugins look for a file named .editorconfig 
> in the directory of the opened file and in every parent directory. A search 
> for .editorconfig files will stop if the root filepath is reached or an 
> EditorConfig file with root=true is found.

In other words, unless root=True is specified, the editor will keep looking for 
.editorconfig also in parent directories as well and composing the config from 
all files it found.

[issue44871] Threading memory leak

[Andrei Zene]

New submission from Andrei Zene :

In an application where we were handling incoming requests in new threads, we 
noticed that the memory usage grew over time. After trying to understand what's 
going on, i was able to reproduce this with a smaller python script that i've 
attached.

What we do:
- start a thread
- the thread allocates some memory
- at some point later we join the thread

Notice that this seems to be more like a race-condition because it doesn't 
reproduce without adding some delays between the creation of different threads. 
I've added a comment in the file that basically commenting one time.sleep makes 
the leak to not reproduce anymore.

On the other side, I was able to reproduce this consistently with every version 
of python on mulitple systems but only on Linux. On windows it doesn't 
reproduce.

[issue40912] _PyOS_SigintEvent is never closed on Windows

[STINNER Victor]

STINNER Victor  added the comment:

Fixed by bpo-41686:

commit 0ae323b87f1bed64a7fa70f5a41a5800aca032cc
Author: Victor Stinner 
Date:   Tue Nov 17 18:15:20 2020 +0100

bpo-41686: Always create the SIGINT event on Windows (GH-23344)

bpo-41686, bpo-41713: On Windows, the SIGINT event,
_PyOS_SigintEvent(), is now created even if Python is configured to
not install signal handlers (PyConfig.install_signal_handlers=0 or
Py_InitializeEx(0)).

Changes:

* Move global variables initialization from signal_exec() to
  _PySignal_Init() to clarify that they are global variables cleared
  by _PySignal_Fini().
* _PySignal_Fini() now closes sigint_event.
* IntHandler is no longer a global variable.

[issue44870] email.message_from_bytes not working on BytesIO() object

[Christian Degenkolb]

New submission from Christian Degenkolb :

Hi, 

the following minimal working example of the problem  

from io import BytesIO
from os import read
import email

fp = BytesIO()

with open('mail.eml', 'rb') as f:
filecontent = f.read()
print("type(filecontent)= ", type(filecontent))
fp.write(filecontent)

mailobj = email.message_from_bytes(fp)

produces the following exception

$ python testparser.py 
type(filecontent)=  
Traceback (most recent call last):
  File "testparser.py", line 16, in 
mailobj = email.message_from_bytes(fp)
  File "/usr/lib/python3.8/email/__init__.py", line 46, in message_from_bytes
return BytesParser(*args, **kws).parsebytes(s)
  File "/usr/lib/python3.8/email/parser.py", line 122, in parsebytes
text = text.decode('ASCII', errors='surrogateescape')
AttributeError: '_io.BytesIO' object has no attribute 'decode'


This is a python 3.8.10 on an Ubuntu 20.04 LTS installed from the packages. 

The documentation for message_from_bytes 
https://docs.python.org/3.10/library/email.parser.html#email.message_from_bytes 
mentions bytes-like objects which links to 
https://docs.python.org/3.10/glossary.html#term-bytes-like-object and 
references object of type byte. 

Shouldn't this work with BytesIO()? A'm I missing something?

with regards
Christian
