[issue41071] from an int to a float , why

[mike stern]

New submission from mike stern :

please I would like to know why python changes an integer result in a division 
to a float even in the result is even

like print(2 / 2) gives 2.0 instead of 2

or 

a = 2 / 2
print(a)

[issue34553] Python Crashes when trying to access any date related fields in MailItem

[Nick Canfield]

Nick Canfield  added the comment:

I'm having trouble with the .ReceivedTime breaking the program when I compile 
the .py script to an .exe using auto-py-to-exe.

Here's where the error occurs underneath this try: statement

try:
received_year = str(email.ReceivedTime)[0:4]
received_month = str(email.ReceivedTime)[5:7]
received_day = str(email.ReceivedTime)[8:10]

This works PERFECTLY well inside of my IDE (PyCharm), but once I've compiled it 
to .exe, it breaks here. 

I've updated pywin32 to the most up-to-date version (228) and also tried using 
224 to see if it was a version issue (it wasn't).

BUT!! Going through this, I FOUND THE BUG! When you compile to .exe with 
auto-py-to-exe, it does not include the package "win32timezone" which the 
.ReceivedTime portion needs to run correctly.

All you have to do to fix this is include this at the top of your .py script 
before compiling to .exe:
import win32timezone

Let me know if this works for anyone else facing this issue!

I cannot reproduce. 2 / 2 gives 1.0 to me.

As for reasons for changing the division operator, read PEP 238.

[issue41073] [C API] PyType_GetSlot() should accept static types

[STINNER Victor]

New submission from STINNER Victor :

To fix bpo-40170, I would like to modify Py_TRASHCAN_BEGIN() macro to use 
PyType_GetSlot() to get the deallocator function, rather than accessing 
directly the PyTypeObject.tp_dealloc member. The problem is that currently 
PyType_GetSlot() only works on heap allocated types.

Would it be possible to add support for statically allocated types to 
PyType_GetSlot()?

Py_TRASHCAN_BEGIN() is currently defined as:

#define Py_TRASHCAN_BEGIN(op, dealloc) \
Py_TRASHCAN_BEGIN_CONDITION(op, \
Py_TYPE(op)->tp_dealloc == (destructor)(dealloc))

[issue40170] [C API] Make PyTypeObject structure an opaque structure in the public C API

[STINNER Victor]

STINNER Victor  added the comment:

> PyIter_Check() and PySequence_ITEM() macros access directly PyTypeObject 
> members and must be converted to opaque functions: (...)

PyIter_Check() and PySequence_ITEM() are declared as functions in the limited C 
API, but overriden with macros in the CPython C API.

I suggest to simply remove the macros to always declare them as functions.

See bpo-33738 "PyIndex_Check conflicts with PEP 384" which added the functions.

See also Tools/scripts/pep384_macrocheck.py script.

Convert posixmodule.c ("posix" or "nt" module) to the multiphase
initialization (PEP 489).

* Create the module using PyModuleDef_Init().
* Create ScandirIteratorType and DirEntryType with the new
  PyType_FromModuleAndSpec() (PEP 573)
* Get the module state from ScandirIteratorType and DirEntryType with
  the new PyType_GetModule() (PEP 573)
* Pass module to functions which access the module state.
* convert_sched_param() gets a new module parameter. It is now called
  directly since Argument Clinic doesn't support passing the module
  to an argument converter callback.
* Remove _posixstate_global macro.

[issue15849] PEP 3121, 384 Refactoring applied to xx module

[STINNER Victor]

STINNER Victor  added the comment:

Fixed by:

commit d5cacbb1d9c3edc02bf0ba01702e7c06da5bc318
Author: Nick Coghlan 
Date:   Sat May 23 22:24:10 2015 +1000

PEP 489: Multi-phase extension module initialization

Known limitations of the current implementation:

- documentation changes are incomplete
- there's a reference leak I haven't tracked down yet

The leak is most visible by running:

  ./python -m test -R3:3 test_importlib

However, you can also see it by running:

  ./python -X showrefcount

Importing the array or _testmultiphase modules, and
then deleting them from both sys.modules and the local
namespace shows significant increases in the total
number of active references each cycle. By contrast,
with _testcapi (which continues to use single-phase
initialisation) the global refcounts stabilise after
a couple of cycles.

[STINNER Victor]

STINNER Victor  added the comment:

The PEP 384 part was fixed by:

commit 04f0bbfbedf8d2bb69b012f853de6648b1a9f27f
Author: Dino Viehland 
Date:   Fri Sep 13 11:12:27 2019 +0100

bpo-38075: Port _randommodule.c to PEP-384 (GH-15798)

- Migrate `Random_Type` to `PyType_FromSpec`
- To simulate an old use of `PyLong_Type.tp_as_number->nb_absolute`, I added
  code to the module init function to stash `int.__abs__` for later
  use. Ideally we'd use `PyType_GetSlot()` instead, but it doesn't currently
  work for static types in CPython, and implementing it just for this case
  doesn't seem worth it.
- Do exact check for long and dispatch to PyNumber_Absolute, use vector 
call when not exact.

Date:   Sat May 23 22:24:10 2015 +1000

PEP 489: Multi-phase extension module initialization

Known limitations of the current implementation:

- documentation changes are incomplete
- there's a reference leak I haven't tracked down yet

The leak is most visible by running:

  ./python -m test -R3:3 test_importlib

However, you can also see it by running:

  ./python -X showrefcount

Importing the array or _testmultiphase modules, and
then deleting them from both sys.modules and the local
namespace shows significant increases in the total
number of active references each cycle. By contrast,
with _testcapi (which continues to use single-phase
initialisation) the global refcounts stabilise after
a couple of cycles.

[issue41074] msilib does not work correctly with non-ASCII names

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

It encodes input string arguments with utf-8 and pass encoded strings to 8-bit 
API which expect they be encoded using the locale encoding. It may pass tests, 
create and read files, but these files will just have wrong names.

[issue41075] Add support of navigating through prev. commands in IDLE

[wyz23x2]

New submission from wyz23x2 :

Terminals like CMD have support of navigating through commands with ↑↓. While 
directly implementing the arrows is not good in IDLE (the use for jumping to 
the prev. line in GUI is needed), there should be a good way.
Some ways:
1. Alt+↑↓. The current behavior is exactly like ↑↓.
2. A "Previous input" option in the right-click menu.
3. A "Navigate" option in the right-click menu. A GUI like this will pop up:
——
┃Navigate┃
┃  × The [4]th command   ┃
┃  O [1] command before  ┃
┃___ ┃
┃┃Paste┃ ┃
┃——— ┃
——

It would be better if 2&3 are together.

[issue41076] Pre-feed the parser with the f-string location

[Lysandros Nikolaou]

New submission from Lysandros Nikolaou :

Inspired by bpo-41064, I sat down to try and find problems with f-string 
locations in the new parser. I was able to come up with a way to compute the 
locations of the f-string expressions that I think is more consistent and 
allows us to delete all the code that was fixing the expression locations after 
the actual parsing, which accounted for about 1/6 of string_parser.c.

A high-level explanation of the change:

Before this change we were pre-feeding the parser with the location of the 
f-string itself. The parser was then parsing the expression and was computing 
the locations of all the nodes based on the offset of the f-string. After the 
parsing was done, we were identifying the offset and the lineno of the 
expression *within* the fstring and were fixing the node locations accordingly. 
For example, for an f-string like `a = 0; f'irrelevant {a}'` we were doing the 
following:

- Pre-feed the parser with lineno=0 and col_offset=7 (the offset of the 
f-string itself in the current line).
- Parse the expression (adding 7 to the col_offset of each parsed node, lineno 
remains the same since it's 0).
- Fix the node locations by shifting the Name node by 14, which is the number 
of characters in the f-string (counting the `f` and the opening quote) before 
the start of the expression.

With this change we now pre-feed the parser with the exact lineno and offset of 
the expression itself, not the f-string. This allows us to completely skip the 
third step of shifting the node locations.

[issue41075] Add support of navigating through prev. commands in IDLE

[Terry J. Reedy]

Terry J. Reedy  added the comment:

There is an old issue proposing making ↑↓ navigate through history in Shell, 
with cntl/alt ↑↓, for instance, navigating through lines.  


In the meanwhile, one is supposed to be able to redefine the abstract 
 and  keys in the Keys tab of the settings 
dialog.  For instance, to Alt-Down and Alt-Up.  However, it is not currently 
working as I expect and I need to investigate more.

A new history list mechanism is a possibility, but I would want to first change 
Shell to only add syntactically correct entries to the permanent list.  One 
should be able to edit a statement until it is correct, just as when trying to 
run from the editor.  This would reduce the need to retrieve history by perhaps 
half (depending on one's syntax knowledge and typing accuracy).

Hi Srinivas, as I said on the PR, cosmetic changes are usually not accepted. 
You can have a look at the other opened bug reports to find issues you can work 
on and at the Python Dev Guide (https://devguide.python.org/) for help to get

[issue41078] [C API] Convert PyTuple_GET_ITEM() macro to a static inline function

[STINNER Victor]

New submission from STINNER Victor :

PyTuple_GET_ITEM() can be abused to access directly the PyTupleObject.ob_item 
member:

   PyObject **items = &PyTuple_GET_ITEM(0);

Giving a direct access to an array or PyObject* (PyObject**) is causing issues 
with other Python implementations, like PyPy, which don't use PyObject 
internally.

I propose to convert the PyTuple_GET_ITEM() and PyList_GET_ITEM() macros to 
static inline functions to disallow that.
