[issue45459] Limited API support for Py_buffer

[Christian Heimes]

Christian Heimes  added the comment:

CC Antoine for his expertise of the buffer protocol

Opaque Py_Buffer and PyObject structs will require a different approach and 
prevent some optimizations. The consumer will have to malloc() a Py_buffer 
struct on the heap. In non-trivial cases the producer (exporter) may have to 
malloc() another blob and store it in Py_buffer.internal [1]. I'm not 
particularly worried about the performance of malloc here.

[issue45514] Deprecate legacy functions from importlib.resources (importlib_resources 5.3)

[Jason R. Coombs]

New submission from Jason R. Coombs :

[importlib_resources 
5.3](https://importlib-resources.readthedocs.io/en/latest/history.html#v5-3-0), 
deprecates the functions in _legacy. Let's introduce that deprecation in 
CPython also.

In addition to merging the changes from importlib_resources, this change will 
require some updates to documentation.

[issue37295] Possible optimizations for math.comb()

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Microbenchmarks:

$ ./python -m pyperf timeit -s 'from math import comb' '[comb(n, k) for n in 
range(63) for k in range(n+1)]'
Mean +- std dev: 1.57 ms +- 0.07 ms -> 209 us +- 11 us: 7.53x faster

$ ./python -m pyperf timeit -s 'from math import comb' 'comb(62, 31)'
Mean +- std dev: 2.95 us +- 0.14 us -> 296 ns +- 11 ns: 9.99x faster

$ ./python -m pyperf timeit -s 'from math import comb' 'comb(110, 15)'
Mean +- std dev: 1.33 us +- 0.06 us -> 95.8 ns +- 3.1 ns: 13.86x faster

$ ./python -m pyperf timeit -s 'from math import comb' 'comb(1449, 7)'
Mean +- std dev: 689 ns +- 33 ns -> 59.0 ns +- 3.2 ns: 11.69x faster

$ ./python -m pyperf timeit -s 'from math import comb' 'comb(3329022, 3)'
Mean +- std dev: 308 ns +- 19 ns -> 57.2 ns +- 4.2 ns: 5.39x faster

Now I want to try to optimize for larger arguments. Perhaps using recursive 
formula C(n, k) = C(n, j)*C(n-j, k-j)//C(k, j) where j=k//2 could help.

[issue45452] Support crash tolerance feature for gdbm module

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

The main concern is that it is not clear how to use this feature, and if it is 
not clear, it will not be used. I am not even sure that it is Pythonic, because 
I do not know how to use it. For example, can it be used to implement 
transactions? How it works with multithreading and multiprocessing if works at 
all? Does it restore after failure automatically or needs some user's action? 
And how do user can know that some actions are required?

[issue19459] Python does not support the GEORGIAN-PS charset

[Tal Einat]

Tal Einat  added the comment:

With recent versions of Python (e.g. 3.9) this no longer causes a crash. Python 
apparently falls back to UTF-8, at least on my system:

$ LANG=ka_GE.georgianps python3.9
Python 3.9.7 (default, Sep  9 2021, 23:20:13) 
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import locale; print(locale.getpreferredencoding())
UTF-8

I'm marking this as fixed. If someone still has issues with this encoding, 
please open a new issue with up-to-date information.

[issue45427] importlib.readers.MultiplexedPath

[David Rajaratnam]

David Rajaratnam  added the comment:

Hi Jason,

Thanks for the extra pointers.  My initial intention in explaining my use-case 
was to find out whether treating an externally embedded  interpreter's files as 
`importlib.resources` is the correct use of this library. However, you're right 
that my explanation turned into a python packaging support question. I'm sorry 
about that.

Thanks for the clarification about the limitations of `as_file()`. I guess that 
means that at the moment it doesn't fully support my use-case, but hopefully 
may do so at some point in the future.

Regards,
Dave

[issue45427] importlib.readers.MultiplexedPath

[Jason R. Coombs]

Jason R. Coombs  added the comment:

Thanks Dave for closing. I would recommend in the future if you have packaging 
questions to bring them to packaging problems repo as indicated at 
https://packaging.python.org/support/#how-to-get-support.

Glad to hear that `as_file` promised to do what you need. Do be aware that it 
doesn't yet support a directory of files (only individual files), a known 
deficiency (https://github.com/python/importlib_resources/issues/228).

I don't have any good advice on separating Python and non-Python code in your 
package. You're right that the current interfaces for supporting package 
resources are specifically designed around resources in a Python package (aka 
package_data).

I agree that there may not be a robust way to locate "data_files". It sounds 
like you have a use-case that's not well served by the current implementation. 
I'd recommend to file a report describing a detailed minimal example of the 
use-case you have and what you'd like to see (in packaging-problems; maybe 
search if someone's already reported). One thing you'll want to answer is where 
do you expect these files to be installed if not in the python package?

Thanks and good luck!

[issue35673] Loader for namespace packages

[Barry A. Warsaw]

Barry A. Warsaw  added the comment:

Since the documentation problem reported here has since been fixed, and really 
all that's left is to expose NamespaceLoader publicly and register it with the 
abc, this is technically a new feature so it can't be backported.  Thus, 
targeting only 3.11.

[issue45452] Support crash tolerance feature for gdbm module

[Dong-hee Na]

Dong-hee Na  added the comment:

Wow, long discussion than I expected, I wish that you don't feel uncomfortable 
with my opinion first :)

> The main concern is that it is not clear how to use this feature, and if it 
> is not clear

IMHO, this feature is similar usage level with gdbm.reorganize() API for 
end-user. 

https://docs.python.org/3/library/dbm.html?highlight=gdbm#dbm.gnu.gdbm.reorganize

I already show you how end-user will use this API in msg404065.
So I don't want to explain the usage again.

> For example, can it be used to implement transactions? 

AFAIk this feature is only used for left snapshot files storing
if the user wants to recover when the user needed.(for example, disk is too old 
so it can cause the system is down, or any disaster situation, or unexpected 
system fault)
And snapshot files can be stored anywhere(separated secondary disk, 
remote-mounted disk.)

So if you can ask snapshot is important? From my side *yes*, it can guarantee 
that we can recover the file when we want to.

IMHO using this API is up to the end user's purpose.

> I am not even sure that it is Pythonic,

Hmm, you mean API signature? Python has a long tradition of being a thin 
wrapper to C functions. (gdbm.reorganize() is a good example)

Since gdbm module is the most accessible python client that today Python users 
can use, I think we have to provide this feature since gdbm authors write this 
feature for end-user usage.
if not authors may not expose those APIs through `gdbmtool`.

FYI, gdbmtool is a CLI tool that you can execute basic gdbms operations.
If you installed gdbm 1.21 on your local machine, you can use crash tolerance 
features simply though gdbmtool

The essential of this feature looks simple.
* If you want to left snapshot files for gdbm, please create the gdbm file 
extension format(X flag) and then execute gdbm_failure_atomic.

If you don't feel the same way, I would like to suggest sending a mailing list 
and I may requests this to gdbms author since they request this issue to me 
through a mail and they are also more expert about gdbm more than me.

Thanks for reading.

[issue45518] Invalid example for typing

[Logan Jones]

Logan Jones  added the comment:

Hi Bozhi. The syntax that you're referencing was added in 3.9. So if you're 
trying the syntax in earlier versions of Python, it won't work. The standard 
collections were added in PEP 585 (https://www.python.org/dev/peps/pep-0585/)

I think the reason the examples use this syntax is that the previous List 
classes were deprecated in favor of the new syntax.

Hope this helps!

[issue45020] Freeze all modules imported during startup.

[Guido van Rossum]

Guido van Rossum  added the comment:

Is gh-28940 only for UNIX?

I built on Windows with default options (PCbuild\build.bat) and it looks like 
the frozen modules are used by default even though I am running in the source 
directory. (I put a printf() call in unmarshal_frozen_code().)

I also put a printf() in is_dev_env() and found that it returns 0 on this check:

/* If dirname() is the same for both then it is a dev build. */
if (len != _Py_find_basename(stdlib)) {
return 0;
}

I assume that's because the binary (in my case at least) is at 
PCbuild\amd64\python.exe which is not the same as my current directory (which 
is the repo root).

[issue45520] Frozen dataclass deep copy doesn't work with __slots__

[Josh Rosenberg]

Josh Rosenberg  added the comment:

When I define this with the new-in-3.10 slots=True argument to dataclass rather 
than manually defining __slots__ it works just fine. Looks like the pickle 
format changes rather dramatically to accommodate it.

>>> @dataclass(frozen=True, slots=True)
... class FrozenData:
... my_string: str
...
>>> deepcopy(FrozenData('initial'))
FrozenData(my_string='initial')

Is there a strong motivation to support manually defined __slots__ on top of 
slots=True that warrants fixing it for 3.10 onward?

[issue26626] test_dbm_gnu

[Zachary Ware]

Zachary Ware  added the comment:

Judging by the error message ("Device or resource busy:"), it seems likely to 
me that NFS was the culprit here.  The fact that the tests passed when run 
alone may point to an issue with the way tests were run as a group, but this 
has changed significantly since 2016.

If this can still be reproduced with modern versions of everything involved, it 
may be worth opening a new issue.  In the meantime, I'm closing this as out of 
date.

Unfortunately, no.  The standard stream replacements were renamed to

I would like to fix this first by adding 'provision for graceful failure'.

[issue9334] argparse does not accept options taking arguments beginning with dash (regression from optparse)

[Tom Karzes]

Tom Karzes  added the comment:

Is there *still* no fix for this?  I keep running into this bug.  People 
sometimes say "oh, it's no problem, just use = to associate the option value 
with the option name".  That is so sad.  It's basically saying "it can't be 
made to work the way it should, so instead use = to introduce your option 
values."  I should *never* have to use = to introduce an option value.

And besides, using = doesn't even handle all cases.  For example, suppose I 
have an option that takes two string arguments, i.e. type=str and nargs=2.  Now 
I want to specify "-x" and "-y" as the two string arguments, like this:

--opt -x -y

As far as I can tell, argparse simply cannot handle this, and there's no 
workaround.  Using = doesn't solve this case.

One more time:  All I want to do is disable the undesirable option look-ahead.  
It is utterly and completely useless to me.  I want sequential, unambiguous 
option parsing.  You know, the way the entire rest of the world does it.  All 
that's needed is something that tells argparse to disable its look-ahead 
heuristic and to simply do what it's told.  Scan left-to-right.  If the next 
string is a recognized option name, then treat it as an option and take its 
arguments from the strings that follow, regardless of what they look like.  
Rinse and repeat.  That is how correct option parsing is done.

All this look-ahead heuristic does is cater to confused beginners, at the cost 
of breaking it for experienced users who know exactly what they want and are 
frustrated that argparse won't let them specify it.

By the way, is there any supported, competing alternative to argparse?  It 
seems like argparse is never going to support option values that begin with 
hyphens, so at this point I'm looking for an alternative that I don't have to 
fight every time I want to allow option values that begin with hyphens.  Maybe 
it's time to create a new option parsing package that supports the most useful 
argparse features, but doesn't mistake option values for option names.  You 
know, something more like optparse, but with some added features.  It just 
needs to support strict left-to-right option parsing.

At this point, I'm thinking it may be time to bite the bullet and write my own 
option parsing package.  One that actually works, and can't be deprecated.  But 
it seems like such a waste of time.  It's hard to fathom why Python no longer 
provides a working option parser.

[issue45519] Minor docstring improvement in __contains__

[Ivan Savov]

New submission from Ivan Savov :

Currently,

```
>>> help(list.__contains__)
```
returns
```
Help on wrapper_descriptor:
__contains__(self, key, /)
Return key in self.
```

Which is a conceptual circular reference,
since `in` is implemented by `__contains__`.

Changing the help string to

"Return True if key in self."

would fix this.

[issue45517] TarFile.add skips files when tarfile name matches a directory

[Jesse Kinkead]

New submission from Jesse Kinkead :

tarfile.open has a "name" parameter that can be used to open a file for reading 
or writing in the local filesystem. The documentation is unclear what the 
purpose is if providing a "fileobj" parameter as well, but it has very 
surprising behavior when the name matches an existing directory.

Specifically, when you provide a "fileobj" for writing and provide a "name" 
that matches an existing directory, calling .add() on that directory will have 
it (and any child files) to be silently skipped.

The desired behavior is either to have the files be added (consistent with 
"name" being totally ignored), or to have it be an error to provide such a 
"name" value (either one that matches an existing directory, or to provide one 
at all when using "fileobj").

[issue34192] FunctionType.__new__ can generate functions that immediately crash

[Dennis Sweeney]

Dennis Sweeney  added the comment:

>From 
>https://github.com/python/cpython/blob/main/Lib/test/crashers/bogus_code_obj.py
> :


"""
Broken bytecode objects can easily crash the interpreter.

This is not going to be fixed.  It is generally agreed that there is no
point in writing a bytecode verifier and putting it in CPython just for
this.  Moreover, a verifier is bound to accept only a subset of all safe
bytecodes, so it could lead to unnecessary breakage.
"""

Since this is messing with implementation details of code objects, I'll close 
this as "won't fix".
