[issue45451] IDLE - modify text frame and widget borders

[primexx]

primexx  added the comment:

for what it's worth, Notepad++ is highly configurable. Here's what mine looks 
like with borders set to 0 and some sidebar items disabled. Even though it is 
the same classic theme, it looks a lot better than default.

There's the more substantial point to note that Notepad++ is not interactive, 
the need to have an extremely tight visual coupling between the margin and the 
main body on a line-per-line basis is significantly reduced. Likewise, the line 
numbers separated by a border in the IDLE editor are not really bothersome 
either, it looks natural enough. It only really sticks out in the interactive 
interpreter.

[issue45959] Teach pprint about dict views

[Raymond Hettinger]

New submission from Raymond Hettinger :

The pprint() code has a number of type or protocol specific handlers but 
doesn't have one for dict views.  So, we don't get pretty printing for the 
key(), values(), and items():

d = {i:i for i in range(100)}
pprint(d) # This is handled correctly
pprint(d.keys())  # Printed on one line
pprint(d.values())# Printed on one line
pprint(d.items()) # Printed on one line

Hi,

I didn't know that and feel sorry to bother you with the non-bug "issue."

Zachary Ware  added the comment:

The `/` denotes that `format` is a positional-only argument; you cannot make a

[issue45958] Document typo in unpack_from()

[Hian-Kun Tenn]

New submission from Hian-Kun Tenn :

In the document of "struct" 
(https://docs.python.org/3.9/library/struct.html#struct.unpack_from), there's 
typo in it.

The document read
`struct.unpack_from(format, /, buffer, offset=0)`
and I believe it should be
`struct.unpack_from(format, buffer, offset=0)`.

Documents before Python 3.9 has no this typo.

[Eric V. Smith]

Eric V. Smith  added the comment:

Maxwell: thank you for your contribution. 

I agree that these don’t belong in the re module.

I think a personal library or something on PyPI (logically equivalent to 
more-itertools) would be more appropriate. 

I suggest closing this as rejected.

[issue45956] Add scanf regular expressions to re

[Raymond Hettinger]

Raymond Hettinger  added the comment:

The scanf() translation table primarily serves as a way to learn regex syntax 
for people who only know scanf syntax.  

It would defeat the educational purpose to immortalize the translation as fixed 
constants.  For the most part, people are better off writing their own 
customizations, for example not using [+-] unless a sign is known to be present.

Also, the table in the docs provides a translation between scanf tokens and 
regex patterns, but it does not assign names to each pattern.  The PR adds 
names but makes confusing choices.  

For example, \S+ in regex notation means "longest sequence contiguous sequence 
of non-space characters".  In the PR, '\S+' is aliased with "whitespace" which 
is the opposite of its usual meaning.

Another problem with the new names is that they take C scanf specific 
definitions and put them in a Python context where we use the words 
differently.  For example, "octal" in scanf means "[-+]?[0-7]+" but in Python 
oct(333) would give '0o515' which includes an 'o' and does not include a '+'.

Overall, I think it would be a mistake to put C world specific aliases into 
Python world.  Instead, it would be better to just leave the table for 
education purposes as it is now.

[issue45356] Calling `help` executes @classmethod @property decorated methods

[Stephen Rosen]

Stephen Rosen  added the comment:

Probably >90% of the use-cases for chaining classmethod are a read-only class 
property.
It's important enough that some tools (e.g. sphinx) even have special-cased 
support for classmethod(property(...)).

Perhaps the general case of classmethod(descriptor(...)) should be treated 
separately from the common case?

> I propose deprecating classmethod chaining.  It has become clear that it 
> doesn't really do what people wanted and can't easily be made to work.

If classmethod(property(f)) is going to be removed, can an implementation of 
classproperty be considered as a replacement?

Or perhaps support via the other ordering, property(classmethod(f))?

hey Irit, Is this issue platform-dependent? I am on ubuntu 20.04, and running

This is what I am getting.
###

hello ...
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

###
and if I replace traceback.print_exception method with the print method, It

[issue45955] Calling read() on HTTPError may cause KeyError in tempfile

[Matt Martz]

New submission from Matt Martz :

HTTPError may not be fully initialized in some scenarios leading to an 
inconsistent interface.  This is documented in code at:

https://github.com/python/cpython/blob/55fe1ae9708d81b902b6fe8f6590e2a24b1bd4b0/Lib/urllib/error.py#L45-L50

Unfortunately the way this is implemented creates an inconsistent interface, 
and opaque code, without a number of inline comments explaining the behavior of 
HTTPError.

Additionally, the way that it currently works, will cause a KeyError to be 
raised from tempfile, which is rather confusing.

Instead of "partially initializing" the HTTPError object, I'd propose that when 
fp is None, that we provide it with something like io.BytesIO to fulfill the 
interface.  There may be other recommended solutions, I've not thought through 
this extensively yet.

I think I just prefer always calling self.__super_init but passing in something 
like io.BytesIO if fp is None

I'm willing to create the PR once I know which direction seems to make the most 
sense.

>>> from urllib.error import HTTPError
>>> from urllib.request import HTTPDigestAuthHandler, 
>>> HTTPPasswordMgrWithDefaultRealm, build_opener
>>> passman = HTTPPasswordMgrWithDefaultRealm()
>>> passman.add_password(None, 'httpbin.org', 'user', 'wrong')
>>> opener = build_opener(HTTPDigestAuthHandler(passman))
>>> try:
... opener.open('https://httpbin.org/digest-auth/auth/user/passwd')
... except HTTPError as e:
... e.read()
...

[issue45954] Rename PyConfig.no_debug_ranges to PyConfig.code_debug_ranges

[STINNER Victor]

New submission from STINNER Victor :

In the PyConfig, I tried to avoid double negative, so "no_debug_ranges" should 
be "debug_ranges". I propose to rename it to "code_debug_ranges" to make it 
more specific.

If there is an agreement on the member name, I can write a PR.

[issue45953] Statically allocate interpreter states as much as possible.

[Eric Snow]

New submission from Eric Snow :

Currently we allocate each new PyInterpreterState in PyInterpreterState_New().  
Furthermore, PyInterpreterState is full of pointers which are almost all 
allocated on the heap during runtime init.  We can statically allocate (and 
initialize?) most of what goes into PyInterpreterState, as well as the main 
interpreter itself (as part of _PyRuntimeState).  This includes each 
interpreter's initial PyThreadState.

TODO:

* [ ] add `PyInterpreterState main;` to _PyRuntimeState.interpreters and use it
* [ ] change references from the pointer to the value
* [ ] add `PyThreadState _main;` to PyInterpreterState.threads and use it
* [ ] change references from the pointer to the value
* [ ] change PyInterpreterState pointer fields to values (as much as possible)
* [ ] change PyThreadState pointer fields to values (as much as possible)


benefits:

* fewer possible failures (no memory) during runtime/interpreter/thread init
* improved memory locality for pointers looked up relative to 
interpreter/thread state


There is one non-trivial bit: embedding the various PyObject values in 
PyInterpreterState and PyThreadState means hard-coding the various pieces of 
the object there (e.g. for dict, its keys/values; for list, its array), as well 
as adding necessary init code to PyInterpreterState_New() and 
PyThreadState_New().  The resulting added complexity can be mitigated somewhat 
with macros or even code generation.  (In fact, there is probably significant 
overlap with Guido's deepfreeze tool.)  Regardless, we'll probably need to 
factor out init funcs for a number of object types, where currently there are 
only "Py*_New()" funcs that combine allocation and init.

[issue45951] Debugger cannot be resolved

[Ben]

New submission from Ben :

First, I am not a programmer by any stretch of the imagination, and I am just 
trying to get this error solved.

I attempted to highlight and comment out a section of code, maybe 20 lines, and 
the program froze, greyed out, and gave me a spinning wheel mouse.

I closed & reopened program, attempted with one line of code and it worked, 
attempted again with 5 lines and same issue occurred.

I have attached a screenshot of the error message and didn't seen how the 
associated error related.  

https://bugs.python.org/issue1180193

The screen was greyed out yes, but I didn't change anything or close the 
program.  I left the night before and when I attempted it this morning it 
started behaving in this manner.

[issue45950] Reintroduce bootstrap_python for freezing

[Christian Heimes]

New submission from Christian Heimes :

bpo-45696 introduced a _bootstrap_python interpreter, which was used to create 
frozen and deepfrozen module files. bpo-45873 dropped the _bootstrap_python 
interpreter again. Instead Python used an existing Python installation to 
bootstrap the build.

After some internal discussion we agreed that the approach is flawed and puts 
too much of a burden on users. Users have to install a fairly recent Python 
interpreter in order to build 3.11. This makes it harder to build Python on 
platforms with no or a too old Python version. It also complicated things for 
container builds and pyenv.

Let's re-introduce a _bootstrap_python interpreter. Cross compiling will still 
require a build Python interpreter.

[issue31196] Blank line inconsistency between InteractiveConsole and standard interpreter

[Malcolm Smith]

Malcolm Smith  added the comment:

I think it's unlikely that anyone is depending on the ability to enter blank 
lines in a "try" block in an InteractiveConsole, especially when blank lines 
terminate the input in almost every other context.

Conversely, everyone who's ever entered a multi-line statement into a Python 
console knows that blank lines usually terminate the input. And they may have 
gotten into the habit, as I did, of using a blank line to abandon an incomplete 
input, and they'll be surprised if it doesn't work in this context. 

On further experimentation, this also affects "def" statements, but only when 
the blank line is at the start of the block, causing the statement to be 
syntactically incomplete.

Native interpreter:

>>> def f():
...
  File "", line 2

^
IndentationError: expected an indented block after function definition on 
line 1

InteractiveConsole:

>>> def f():
...
...
...   pass
...
>>>

So I think the current behavior is likely to annoy a much larger number of 
people, but whoever's responsible for this part of the standard library will 
have to judge that for themselves.

[issue45949] Provide pure-Python implementation of Programs/_freeze_module for cross building

[Christian Heimes]

New submission from Christian Heimes :

As of today 3.11-dev requires Programs/_freeze_module to compile Python code to 
byte code. The dependency on an extra and special tool makes cross building 
more complicated. The _freeze_module is trivial and can be easily implemented 
in pure Python code. The re-introduction of _bootstrap_python helper would 
allow us to use a pure Python freeze_module for all modules except two 
importlib bootstrap modules. I have a proof of concept implementation that 
works for me.

Proposal for standard builds:
- Use Programs/_freeze_module to create 
Python/frozen_modules/importlib._bootstrap.h and 
Python/frozen_modules/importlib._bootstrap_external.h
- build _bootstrap_python
- use new tool "./_bootstrap_python Tools/scripts/freezemodule.py" to create 
remaining Python/frozen_modules/*.h

Proposal for cross builds:
- use user-provider Python interpreter (./configure --with-build-python) to 
generate all Python/frozen_modules/*.h with new freezemodule.py tool.

When cross building the user must already provide a Python interpreter with 
same version and bytecode version as the build target. Users would no longer 
need to provide a _freeze_module binary with ./configure --with-freeze-module.

[issue45947] Place dict (and values) pointers at a fixed (negative) offset from the base of the object.

[Mark Shannon]

New submission from Mark Shannon :

To get to the dict (or values array) of an object, we currently need 3 
dependent loads.
By placing the dict at a fixed offset, this can be reduced to one.

What was `obj[obj->type->dictoffset]` becomes `obj[FIXED_OFFSET]`

See https://github.com/faster-cpython/ideas/issues/80, specifically
https://github.com/faster-cpython/ideas/issues/80#issuecomment-931504847 for

[issue45476] [C API] PEP 674: Disallow using macros as l-value

[STINNER Victor]

STINNER Victor  added the comment:

I updated my ./search_pypi_top_5000.py script to ignore files generated by 
Cython.

On PyPI top 5000, I only found 16 projects impacted by the PEP 674 (16/5000 = 
0.3%):

* datatable-1.0.0
* frozendict-2.1.1
* guppy3-3.1.2
* M2Crypto-0.38.0
* mecab-python3-1.0.4

* python-snappy-0.6.0
* recordclass-0.16.3
* scipy-1.7.3
* zodbpickle-2.2.0

I ignored manually two false positives in 3 projects:

* "#define __Pyx_SET_SIZE(obj, size) Py_SIZE(obj) = (size)" in Cython
* "* Py_TYPE(obj) = new_type must be replaced with Py_SET_TYPE(obj, new_type)":

That would make InteractiveConsole more restrictive and break code that is 
currently working. It could also be annoying and throw off somebody's flow.

[issue39529] Deprecate get_event_loop()

[Andrew Svetlov]

Andrew Svetlov  added the comment:

Ages ago, get_event_loop() did not return the current running loop if called 
from async function context; it returned a loop instance registered with 
previous set_event_loop(...) call instead.

Later we fixed get_event_loop() behavior in 3.5.4 IIRC and added 
get_running_loop() in 3.7

set_event_loop() doesn't make sense now from my perspective.

[issue31196] Blank line inconsistency between InteractiveConsole and standard interpreter

[Malcolm Smith]

Malcolm Smith  added the comment:

I agree that both behaviors are reasonable. However, the InteractiveConsole 
documentation says it should "closely emulate the behavior of the interactive 
Python interpreter". Since people are familiar with the native interpreter, any 
difference in behavior is potentially annoying and could throw off somebody's 
flow. So I think the InteractiveConsole should be changed to match the native 
interpreter.

Like the native interpreter, InteractiveConsole allows other multi-line blocks 
to be terminated with a blank line:

>>> def foo(x):
...   pass
...
>>> for x in [1,2,3]:
...   pass
...
>>>


I guess the reason why "try" is different is that a "try" block isn't a 
complete statement on its own. If you follow it with an "except" block, then 
that can indeed be terminated with a blank line.

[issue45944] Avoid calling isatty() for most open() calls

[Eryk Sun]

Eryk Sun  added the comment:

> make it returning False without invoking a system call if the file
> size is non-zero it will eliminate the need to expose _size.

I suggest using the file type instead of the size. There's no reason to call 
isatty() if it's not an S_IFCHR file. This will avoid calling isatty() on 
regular files that happen to be empty.

In Windows, isatty(fd) is based solely on the file type, which is flagged in 
the fd record when a file descriptor is opened for a native file handle. It's 
not a system call, but it's also nearly worthless for how isatty() is typically 
used, since it's true for any S_IFCHR file (e.g. con, nul, com1).
