[issue47105] [Doc] grp cites pwd.h instead of grp.h

[Alex Hedges]

New submission from Alex Hedges :

The documentation page for the grp module says to "see ", even though 
the source code 
(https://github.com/python/cpython/blob/v3.11.0a6/Modules/grpmodule.c) uses 
grp.h.

I plan to release a PR for this shortly.

[issue46864] Deprecate ob_shash in BytesObject

[Inada Naoki]

Inada Naoki  added the comment:

First of all, this is just deprecating direct access of `ob_shash`. This makes 
users need to use `PyObject_Hash()`.
We don't make the final decision about removing it. We just make we can remove 
it in Python 3.13.

RAM and CACHE efficiency is not the only motivation for this.
There is a discussion about (1) increasing CoW efficiency, and (2) sharing data 
between subinterpreters after per-interpreter GIL.
Removing ob_shash will help them, especially about the (2).

But if we stop using bytes objects in code objects by Python 3.13, there is no 
need to remove ob_shash.


> If put a bytes object into multiple dicts/sets, the hash need to be computed 
> multiple times. This seems a common usage.

Doesn't it lose only some milliseconds?
I posted remove-bytes-hash.patch in this issue. Would you measure how this 
affects whole application performance rather than micro benchmarks?

[issue47000] Make encoding="locale" uses locale encoding even in UTF-8 mode is enabled.

[Inada Naoki]

Inada Naoki  added the comment:

I am not sure about we really need "locale encoding at Python startup".

For this issue, I don't want to change `encoding="locale"` behavior except 
ignore UTF-8 mode. So what I want is "current locale encoding" or 
 ANSI codepage on Windows.

On the other hand, I know Eryk wants to support locale on Windows. So 
`locale.get_encoding()` might return current locale encoding (not ANSI 
codepage) even on Windows.
If so, I will use `sys.getlocaleencoding()` to implement `encoding="locale"` to 
keep using ANSI codepage, instead of adding yet another "get locale encoding" 
function.

[issue39298] add BLAKE3 to hashlib

[Larry Hastings]

Larry Hastings  added the comment:

> Performance wise... The SHA series have hardware acceleration on
> modern CPUs and SoCs.  External libraries such as OpenSSL are in a

I don't know if OpenSSL currently uses the Intel SHA1 extensions.
A quick google suggests they added support in 2017.  And:

* I'm using a recent CPU that AFAICT supports those extensions.
  (AMD 5950X)
* My Python build with BLAKE3 support is using the OpenSSL implementation
  of SHA1 (_hashlib.openssl_sha1), which I believe is using the OpenSSL
  provided by the OS.  (I haven't built my own OpenSSL or anything.)
* I'm using a recent operating system release (Pop!_OS 21.10), which
  currently has OpenSSL version 1.1.1l-1ubuntu1.1 installed.
* My Python build with BLAKE3 doesn't support multithreaded hashing.
* In that Python build, BLAKE3 is roughly twice as fast as SHA1 for
  non-trivial workloads.

Rather than trying to set up PATH properly, we should just copy pgort140.dll

   301426 5 files

I didn't run any benchmarks, but it's clear that the SIMD code was
used in my initial build and this adds some 50kB to the .so file.
This is on a older Linux x64 box with Intel i7-4770k CPU.

Could be that the Rust version adds several such SIMD variants and
then branches based on the platform running the code.

In any case, the C extension is indeed very easy to build and
install with a standard compiler setup.

Gregory P. Smith  added the comment:

Performance wise... The SHA series have hardware acceleration on modern CPUs 
and SoCs.  External libraries such as OpenSSL are in a position to provide 
implementations that make use of that. Same with the Linux Kernel CryptoAPI 
(https://bugs.python.org/issue47102).

Hardware accelerated SHAs are likely faster than blake3 single core. And 
certainly more efficient in terms of watt-secs/byte.

[issue39298] add BLAKE3 to hashlib

[Gregory P. Smith]

Gregory P. Smith  added the comment:

To anyone else who comes along with motivation:

I'm fine with blake3 being in hashlib, but I don't want us to guarantee it by 
carrying the implementation of the algorithm in the CPython codebase itself 
unless it gains wide industry standard-like adoption status.

We should feel free to link to both the Rust blake3 and C blake3-py packages 
from the hashlib docs regardless.

[issue47102] explore hashlib use of the Linux Kernel CryptoAPI

[Gregory P. Smith]

New submission from Gregory P. Smith :

Linux kernels provide a CryptoAPI. This is a common place for platform specific 
hardware accelerated hash algorithms to be exposed to the user (especially on 
SoCs which often have non-standard hardware).

https://www.kernel.org/doc/html/v4.10/crypto/userspace-if.html
https://www.kernel.org/doc/html/v5.17/crypto/userspace-if.html
https://www.chronox.de/libkcapi.html

hashlib currently uses OpenSSL when possible for performance.  We could also 
look at querying the kernel API.  How to decide between the two implementations 
when both are present is something TBD.

This would probably be best done via a configure time check for libkcapi?

[issue39298] add BLAKE3 to hashlib

[Larry Hastings]

Larry Hastings  added the comment:

I can't answer why the Rust one is so much larger--that's a question for Jack.  
But the blake3-py you built might (should?) have support for SIMD extensions.  
See the setup.py for how that works; it appears to at least try to use the SIMD 
extensions on x86 POSIX (32- and 64-bit), x86_64 Windows, and 64-bit ARM POSIX.

If you were really curious, you could run some quick benchmarks, then hack your 
local setup.py to not attempt adding support for those (see "portable code 
only" in setup.py) and do a build, and run your benchmarks again.  If BLAKE3 
got a lot slower, yup, you (initially) built it with SIMD extension support.

With "lean" I meant: doesn't use much code and is easy to compile
and install.

I built a wheel from Jack's experimental package and it comes out to
just under 100kB on Linux x64, compared to around the 1.1MB the
Rust wheel needs:

I don't know why there is such a significant difference in size. Perhaps
the Rust version includes multiple variants for different CPU
optimizations ?!

[issue46964] The global config should not be stored on each interpreter

[STINNER Victor]

STINNER Victor  added the comment:

> thus far we have had no actual use cases for initializing an interpreter
>  with a different config

I don't think that sub-interpreters should have 
config.install_signal_handlers=1. Same for config.configure_c_stdio=1. Only the 
main interpreter should handle signals and the configuration of C streams 
(stdio, stderr, stdio).

I added _PyInterpreterState_SetConfig() to experiment changing 
config.bytes_warning. But this is no strong need to have an API to change it, 
so right now, there is still no API for that. If we allow to change it, it 
would be surprising to change all interpreters at once.

I don't see why config.argv (sys.argv) must be the same in all interpreters. 
Same for config.module_search_paths (sys.path).

For me, it makes sense to have a per-interpreter value for most PyConfig 
options.

> * there is no API for creating an interpreter with a different config

There is _Py_NewInterpreter(int isolated_subinterpreter) to set 
config.config._isolated_interpreter. But since the feature is not "official", 
it remains a private API.


> currently, every interpreter uses (a copy of) the original PyConfig,
> completely unchanged

Currently, it's possible to call Py_InitializeFromConfig() (or Py_Initialize()) 
multiple times and it changes the PyConfig of the current interpreter. See the 
pyinit_core_reconfigure() function. _testembed has an unit test for that: I had 
to implement this feature. Once, calling the function multiple times and it 
broke an application. See bpo-34008.

[issue39298] add BLAKE3 to hashlib

[Larry Hastings]

Larry Hastings  added the comment:

The Rust version is already quite "lean".  And it can be much faster than the C 
version, because it supports internal multithreading.  Even without 
multithreading I bet it's at least a hair faster.

Also, Jack has independently written a Python package based around the C 
version:

  https://github.com/oconnor663/blake3-py/tree/master/c_impl

so my making one would be redundant.

I have no interest in building standalone BLAKE3 PyPI packages for Raspberry Pi 
or Android.  My goal was for BLAKE3 to be one of the "included batteries" in 
Python--which would have meant it would, eventually, be available on the 
Raspberry Pi and Android builds that way.

Sorry to spoil the fun, but there's no need to throw
everything in the bin ;-)

A lean and fast blake3 C package would still be a great thing
to have on PyPI, e.g. provide support for platforms, which
Jack's blake3 Rust package doesn't cover, e.g.

Raspis:
https://www.piwheels.org/project/blake3/

Android (e.g. via termux):
https://wiki.termux.com/wiki/Main_Page
https://wiki.termux.com/wiki/Python

etc.

[issue44090] Add class binding to unbound super objects for allowing autosuper with class methods

[Géry]

Géry  added the comment:

Apologies for the long delay.

> Do we have any meaningful examples to show that this is desired and useful?

A use case of `super()` in a `classmethod` that comes to mind is for 
parameterized factory methods. It is a variation of the classic factory method 
design pattern that lets the factory method of a creator creates *multiple* 
products according to a parameter identifying the product to create. Overriding 
the factory method lets you change or extend the products that are created, by 
mapping existing identifiers to different products or introducing new 
identifiers for new products (cf. GoF’s book *Design Patterns*, section 
‘Factory Method’, subsection ‘Implementation’, paragraph 2):

```
>>> class MyCreator:
... @classmethod
... def make(cls, product_id):
... if product_id == 'mine': return MyProduct(creator=cls)
... if product_id == 'yours': return YourProduct(creator=cls)
... if product_id == 'theirs': return TheirProduct(creator=cls)
... raise ValueError('product_id {!r} not supported'.format(product_id))
... 
>>> class YourCreator(MyCreator):
... @classmethod
... def make(cls, product_id):
... if product_id == 'mine': return YourProduct(creator=cls)
... if product_id == 'yours': return MyProduct(creator=cls)
... return super(YourCreator, cls).make(product_id)
... 
>>> class BaseProduct:
... def __init__(self, creator): self._creator = creator
... def __repr__(self):
... return '{}(creator={})'.format(
... type(self).__name__, self._creator.__name__)
... 
>>> class MyProduct(BaseProduct): pass
... 
>>> class YourProduct(BaseProduct): pass
... 
>>> class TheirProduct(BaseProduct): pass
... 
>>> MyCreator.make('mine')
MyProduct(creator=MyCreator)
>>> YourCreator.make('mine')
YourProduct(creator=YourCreator)
```

[issue47101] hashlib.algorithms_available lists algorithms that are not available in OpenSSL 3.0 default provider

[Christian Heimes]

New submission from Christian Heimes :

Hubert Kario wrote in https://bugzilla.redhat.com/show_bug.cgi?id=2054702

Description of problem:
The hashlib.algorithms_available set includes algorithms like ripemd160 and 
whirlpool, those algorithms are not usable unless openssl legacy provider is 
loaded. Since it's not loaded, and the hashlib module won't load it, any 
attempt to use them fails.

Version-Release number of selected component (if applicable):
python3-3.9.10-1.el9.x86_64
openssl-3.0.1-5.el9.x86_64

How reproducible:
always

Steps to Reproduce:
0. start python3
1. from hashlib import algorithms_available 
2. algorithms_available
3. import hashlib
4. a = {(name, hashlib.new(name).digest_size) for name in algorithms_available}

Actual results:

'sha3_256', 'shake_128', 'sm3', 'sha256', 'sha512', 'sha1', 'shake_256', 
'blake2b', 'whirlpool', 'sha512_256', 'sha3_224', 'sha224', 'ripemd160', 'md4'}

Traceback (most recent call last):

Expected results:

'sha3_256', 'shake_128', 'sm3', 'sha256', 'sha512', 'sha1', 'shake_256', 
'blake2b', 'sha512_256', 'sha3_224', 'sha224'}

16), ('sha224', 28), ('shake_128', 0), ('sm3', 32), ('blake2s', 32), ('sha1', 
20), ('shake_256', 0), ('sha512_256', 32), ('sha3_224', 28), ('sha3_256', 32), 
('sha3_384', 48), ('sha384', 48), ('sha256', 32), ('sha512_224', 28)}

Additional info:
If the legacy provider is loaded, then the algorithms should be listed and 
should work.

It may be caused by Python using the deprecated EVP_MD_do_all() method instead 
of the EVP_MD_do_all_provided() method

[issue28080] Allow reading member names with bogus encodings in zipfile

[Stephen J. Turnbull]

Stephen J. Turnbull  added the comment:

I'm not going to have time to look at the PR for a couple days.

I don't understand what the use case is for writing or appending with filenames 
in a non-UTF-8 encoding.  At least in my experience, reading such files is 
rare, but I have never been asked to write one.  The correspondents who send me 
zipfiles with the directory encoded in shift_jisx0213 are perfectly happy to 
read zipfiles with the directory encoded in UTF-8.

If that is true for other users, then unzipping the file to a temporary 
directory with the appropriate --metadata-encoding, adding the required paths 
there, and zipping a new archive seems perfectly workable.  In that case making 
this feature read-only makes the most sense to me.

[issue46975] clang: error: linker command failed with exit code 1 (use -v to see invocation) on m1 mac

[Jason R. Coombs]

Jason R. Coombs  added the comment:

Aha. If I configure/make without LDFLAGS or CPPFLAGS set, compilation works. 
Then I noticed for `LDFLAGS`, some users were using `-L`. I thought it was 
slightly odd that my recipe was using `-I` for both flags. How is it that [this 
mistake](https://github.com/jaraco/jaraco.develop/commit/6469c7a61e7349b93f191df38eed6cd020dd79be)
 hasn't caused me any grief until M1 build?  No matter - correcting for that 
mistake and passing the correct LDFLAGS flag (-L) corrects for the issue.

As suggested, I uninstalled and reinstalled everything in homebrew:

$ brew list | xargs brew remove
$ brew install python@3.10 python-launcher python@3.9 python@3.8 gh git

Even after following those steps and setting LDFLAGS and CPPFLAGS to point to 
`brew --prefix`, the errors continue when running `./configure; make` in a 
clean checkout.

[This

I noticed [this

reports the same issue I have, but no solution is present.

I saw a suggestion to [set

I do that [as a matter of

I don't have an x86 install of homebrew. This machine is less than a month old 
and has had ARM-based homebrew installed from the beginning.

I'll keep investigating.

[issue47000] Make encoding="locale" uses locale encoding even in UTF-8 mode is enabled.

[STINNER Victor]

STINNER Victor  added the comment:

sys.getlocaleencoding() versus locale.getencoding().

For me, the Python locale module should use the C API to access the Unix 
locales like LC_CTYPE, nl_langinfo(CODESET), etc.

The sys module are more for things specific to Python, like 
sys.getfilesystemencoding().

Since sys.getlocaleencoding() would be a fixed value for the whole process life 
time, I agree that the sys module is a better place.

I can write a PR adding sys.getlocaleencoding() if we agree on the API.

[issue46864] Deprecate ob_shash in BytesObject

[Ma Lin]

Ma Lin  added the comment:

If put a bytes object into multiple dicts/sets, the hash need to be computed 
multiple times. This seems a common usage.

bytes is a very basic type, users may use it in various ways. And unskilled 
users may checking the same bytes object against dicts/sets many times.

FYI, 1 GiB data:

function seconds
hash()   0.40
binascii.crc32() 1.66   (Gregory P. Smith is trying to improve this)
zlib.crc32() 0.65

[issue47099] Replace with_traceback() with exception chaining and reraising

[Oleg Iarygin]

New submission from Oleg Iarygin :

Currently, exception chaining in Lib/ modules is implemented with pre-3.11 
`raise Foo(...).with_traceback(sys.exc_info()[2])`. However, this approach can 
be simplified:

1. PEP 3134 introduced a proper `raise Foo(...) from bar` construction that 
takes a parent exception instead of its stack traceback

2. Without the traceback required, we partially get rid of `sys.exc_info` thus 
reducing active tapping into global internals

A report printed into a console remains the same except a line:

> During handling of the above exception, another exception occurred

replaced with:

> The above exception was the direct cause of the following exception

[issue39298] add BLAKE3 to hashlib

+1 on this. I also think the topic deserves a wider discussion.

IMO, Python's stdlib should only provide a basic set of hash algorithms
and not try to add every single new algorithm out there.

PyPI is a much better way to add support for new hash algorithms,
can move much faster than the stdlib, provide specialized builds for
added performance and also add exotic features, which are not always
needed.

Here's the list of Python 3.10 algos on a typical Linux system:

>>> hashlib.algorithms_available
{'sha512_256', 'mdc2', 'md5-sha1', 'md4', 'ripemd160', 'shake_128', 'sha3_384',
'blake2s', 'sha3_512', 'sha3_256', 'sha256', 'sha1', 'sm3', 'sha512_224',
'whirlpool', 'sha384', 'shake_256', 'sha224', 'sha512', 'sha3_224', 'md5',
'blake2b'}

This already is more than enough. Since we're using OpenSSL in Python
anyway, exposing some of the often used algos from OpenSSL is fine,
since it doesn't add much extra bloat. The above list already goes
way beyond this, IMO.

The longer the list gets, the more confusion it causes among users,
since Python's stdlib doesn't provide any guidance on
basic questions such as "Which hash algo should I use for my
application".

Most applications today will only need these basic hash algos:

{'ripemd160', 'sha3_512', 'sha3_256', 'sha256', 'sha1', 'sha512', 'md5'}

[issue47098] sha3: Replace Keccak Code Package with tiny_sha3

[Christian Heimes]

New submission from Christian Heimes :

The Keccak Code Package (kcp) provides the reference implementation for SHA3 
and SHAKE hashing algorithms. CPython has vendored a copy of KCP since I added 
SHA3 in 3.6.

CPython 3.10 and newer require OpenSSL >= 1.1.1, which provide an optimized 
implementation of SHA3 and SHAKE on all platforms. The vast majority of users 
now use SHA3 from OpenSSL instead our _sha3 module with KCP. Both the KCP and 
_sha3 module are large. The KCP has 230kB of code. The _sha3 shared library is 
390kB on Linux X86_64, stripped 90kB.

I would like to reduce the size of our bundled code. Since SHA3 and SHAKE are 
listed in hashlib.algorithms_guaranteed and OpenSSL is optional, we cannot just 
drop the _sha3 module. Instead I propose to replace the implementation with 
tiny_sha3 https://github.com/mjosaarinen/tiny_sha3 . The tiny implementation is 
13 kB of code. The resulting _sha3 shared library is 69 kB (stripped 25 kB).

A Python build without OpenSSL bindings will have a working but slower SHA3 
implementation.
