[issue46869] platform.release() and sys returns wrong version on Windows 11

[Eryk Sun]

Eryk Sun  added the comment:

platform.release() returns platform.uname().release, which comes from 
platform.win32_ver() in Windows [1]. The issue with Windows 11 is being 
discussed in bpo-45382, but no PR has been submitted yet to resolve the issue.

> >>> sys.getwindowsversion().platform_version
> (10, 0, 22000)

This result is correct [2], but you should use platform.version() instead. The 
major.minor version of Windows 11 is 10.0. The build number for Windows 11 is 
22000 and above. The latest build number for Windows 10, in contrast, is 19044.

The system version number concerns API compatibility, not user-interface 
updates or marketing names. Windows XP, XP Professional x64 Edition, Vista, 7, 
8, and 8.1 correspond respectively to Windows system versions 5.1, 5.2, 6.0, 
6.1, 6.2, and 6.3. System versions 7.x, 8.x, and 9.x were skipped. Version 10.0 
is the first system version with two client workstation releases, Windows 10 
and Windows 11. It's thus the first time that the build number is required to 
differentiate the release name.

The `platform_version` attribute of the sys.getwindowsversion() result is 
supposed to be the true OS version in case the API is using a 
compatibility-mode version. It's based on the product version of the system 
file "kernel32.dll". However, it turns out that this is also not reliably the 
true OS version. The sys documentation was updated with a note that suggests 
using the platform module instead [3].

It's more about whether you consider that list(chain(...)) is a clear
and readable idiom, or you prefer to give a name to it. Not every
two-operation action needs its own name.

[issue28824] os.environ should preserve the case of the OS keys ?

[Eryk Sun]

Eryk Sun  added the comment:

> I think there should be a public class like this.

I wrote a basic implementation of _CaseInsensitiveString under the assumption 
that it's hidden behind the __getitem__(), __setitem__(), and __delitem__() 
methods of the _Environ class. I don't want to complicate the implementation.

The problem of case-insensitive names in file/registry paths and environment 
variables should be addressed with ntpath.normcase(). This should be based on 
WinAPI LCMapStringEx() with LOCALE_NAME_INVARIANT and LCMAP_UPPERCASE. The 
current implementation of ntpath.normcase() uses str.lower(), which depends on 
Python's Unicode database. This possibly differs from what Windows considers to 
be lower case in the invariant locale. It's also wrong because Windows uses 
upper case for cases-insensitive comparisons, which matters when sorting names. 
See bpo-42658.

> Right now, it's not a good workaround because it contains the

> current environment.

Note that in some cases the "current environment" is the process environment, 
which isn't necessarily consistent with os.environ on any platform.

In POSIX, posix.environ is created from C environ, which is kept in sync with 
changes to posix.environ via C putenv() and unsetenv(). However, directly 
calling os.putenv() or os.unsetenv(), or the underlying C functions, modifies 
the process environment without changing posix.environ. If subprocess.Popen() 
is called without overriding env, the child inherits the process environment, 
not posix.environ.

In Windows, os.environ is created from nt.environ, with variables names 
converted to upper case. nt.environ is created from C _wenviron, which is 
created from the process environment, as returned by WinAPI 
GetEnvironmentStringsW(), except with variable names that begin with "=" 
filtered out. os.putenv() and os.unsetenv() are based on C _wputenv(), which 
updates C _wenviron and also updates the process environment via WinAPI 
SetEnvironmentVariableW(). If either os.putenv() or os.unsetenv() is called 
directly, or _wputenv() at a lower level, then the variables in C _wenviron 
(not just the letter case of the names) will be out of sync with os.environ. 
Additionally, if SetEnvironmentVariableW() is called directly to set or unset a 
variable, then both os.environ and C _wenviron will be out of sync with the 
process environment. If subprocess.Popen() is called without overriding env, 
the child inherits the process environment, not os.environ or C _wenviron.

[issue29251] [doc] Class __dict__ is only a mapping proxy

[Stanley]

Stanley  added the comment:

>From what I can see, the original patch changed

... and the *dict* dictionary is the namespace containing definitions for class 
body and is copied to a standard dictionary to become the __dict__ attribute

into this

... and the *dict* dictionary is copied to the namespace containing definitions 
for the class body, which is referenced by the __dict__ attribute

so that the documentation avoids saying that the attribute is a dictionary, 
instead saying it just references a dictionary. However, current documentation 
says that

... it may be copied or wrapped before becoming the __dict__ attribute

which implies some sort of change already. In this case, is the patch for the 
functions page still applicable?

[issue46871] BaseManager.register no longer supports lambda callable 3.8.12+

[Steven D'Aprano]

Steven D'Aprano  added the comment:

Works for me in Python 3.10.0 on Linux.

After running your code, I get shared_dict is a DictProxy:

>>> shared_dict

>>> list(shared_dict.items())
[('number', 0), ('text', 'Hello World')]

and shared_lock an AcquirerProxy object.

Please double-check that the code you posted is the actual code that is 
failing, and copy and paste the full traceback you receive, not just a one-line 
summary.

Even if the error is reproducible, I doubt that the cause is what you state in 
the title of this issue:

BaseManager.register no longer supports lambda callable

Lambdas are just functions, they aren't a different type of callable. So the 
register method cannot distinguish between a lambda argument written directly 
in place, and a named def defined earlier then passed by name. So whatever 
error might be happening on your system, I doubt it has anything to do with the 
use of lambda syntax

[issue46868] Improve performance of math.prod with bignums (and functools.reduce?)

[Tim Peters]

Tim Peters  added the comment:

I don't know that there's a good use case for this. For floating addition, 
tree-based summation can greatly reduce total roundoff error, but that's not 
true of floating multiplication.

The advantage for prod(range(2, 50001)) doesn't really stem from turning it 
into a tree reduction, but instead for that specific input sequence "the tree" 
happens to do a decent job of keeping multiplicands more-or-less balanced in 
size (bit length), which eventually allows Karatsuba multiplication to come 
into play. If CPython didn't implement Karatsuba multiplication, tree reduction 
wouldn't improve speed: if the inputs are in sequence xs, regardless how 
school-book multiplication is grouped, or rearranged, the time needed is 
proportional to

sum(a * b for a, b in combinations([x.bit_length() for x in xs], 2))

So if the real point is to speed large products of integers, a different 
approach is wanted: keep track of intermediate products' bit lengths, and at 
each step strive to multiply partial products near the same length. This will 
reliably get Karatsuba into play if possible, and caters too to that Karatsuba 
is most valuable on multiplicands of the same bit length. When any of that 
happens from blind tree reduction, it's down to luck.

I've seen decent results from doing that with a fixed, small array A, which 
(very roughly speaking) combines "the next" integer `i` to multiply with the 
array entry A[i.bit_length().bit_length()] (and continues that with the new 
partial product, & so on, until hitting an array slot containing 1).

[issue46871] BaseManager.register no longer supports lambda callable 3.8.12+

[Kyle Smith]

New submission from Kyle Smith :

The below code works on versions 3.5.2 to 3.8.10. Higher versions tested, such 
as 3.9.12 and 3.10.2 result in the error:
 "AttributeError: Can't pickle local object".


from multiprocessing import Lock

manager.register("get_dict", lambda: shared_dict, DictProxy)
manager.register("get_lock", lambda: shared_lock, AcquirerProxy)
try:

return manager.get_dict(), manager.get_lock()

HOST = "127.0.0.1"
PORT = 35791

I will reconsider the removal before remove the cache.
We changed code object too often. If Python 3.13 don't use so much bytes 
objects, we don't need to remove the hash to save some RAM.

Re: How to solve the given problem?

On Sat, 26 Feb 2022 02:49:15 -0800 (PST), NArshad 
declaimed the following:

>Its better to adjust the feed in the coming next two feeds that is the third

Is there a question in that?

It's your assignment -- you will have to justify your design to whoever
gave you that assignment. So far all you have is a statement with no
justification.

And you really do need to justify the part where you seem to ignore
"distribute the remaining 40 unit in the rest of the day" and "Try to keep
the distribution similar to the current feeding pattern."

If you really wanted to provide a /generalized/ solution then "40
units" will never appear IN THE CODE. A generalized solution would accept
two lines of input: the original/planned schedule (for the whole day) and,
the implemented schedule up to when the mistake was detected. It would then
generate a new schedule for the rest of the day taking into account what
had already been done. (PLANNED and ACTUAL are input, ADJUSTED is output)

PLANNED:15010030303020201055
ACTUAL: 15060

ADJUSTED:   

Note that a generalized solution would handle

PLANNED:15010030303020201055
ACTUAL: 15060  30

ADJUSTED:   

where the mistake was on the second feed, but not discovered until after
the third feed.

Haven't looked much at Fortran-90/95 then... 

Variable declaration gained a POINTER qualifier, and there is an
ALLOCATE intrinsic to obtain memory.

And with difficulty one could get the result in DEC/VMS FORTRAN-77
since DEC implemented (across all their language compilers) intrinsics
controlling how arguments are passed -- overriding the language native
passing: 
CALL XYZ(%val(M))
would actually pass the value of M, not Fortran default address-of, with
the result that XYZ would use that value /as/ the address of the actual
argument. (Others were %ref() and %descr() -- descriptor being a small
structure with the address reference along with, say, upper/lower bounds;
often used for strings).

[issue46845] dict: Use smaller entry for Unicode-key only dict.

Inada Naoki  added the comment:

I added _PyDict_FromItems() to the PR.
It checks that all keys are Unicode or not before creating dict.
_PyDict_NewPresized() just returns general-purpose dict. But it isn't used from 
CPython core. It is just kept for compatibility (for Cython).

```
$ ./python -m pyperf timeit --compare-to ../cpython/python -- '{"k1":1, "k2":2, 
"k3":3, "k4":4, "k5":5, "k6":6}'

```

Overhead of checking keys types is not so large.
Additionally, we can reduce some code from ceval.c.

Inada Naoki  added the comment:

This change doesn't affect to os.environ.

os.environ[key] does `key.encode(sys.getfilesystemencoding(), 
"surrogateescape")` internally. So the encoded key doesn't have cached hash.
On the other hand, dict (`self._data`) has own hash cache. So it don't use hash 
cached in the bytes objects.

On the other hand, this change will affect `os.environb[key]` if key is used 
repeatedly.

[issue46868] Improve performance of math.prod with bignums (and functools.reduce?)

[benrg]

New submission from benrg :

math.prod is slow at multiplying arbitrary-precision numbers. E.g., compare the 
run time of factorial(5) to prod(range(2, 50001)).

factorial has some special-case optimizations, but the bulk of the difference 
is due to prod evaluating an expression tree of depth n. If you re-parenthesize 
the product so that the tree has depth log n, as factorial does, it's much 
faster. The evaluation order of prod isn't documented, so I think the change 
would be safe.

factorial uses recursion to build the tree, but it can be done iteratively with 
no advance knowledge of the total number of nodes.

This trick is widely useful for turning a way of combining two things into a 
way of combining many things, so I wouldn't mind seeing a generic version of it 
in the standard library, e.g. reduce(..., order='mid'). For many specific cases 
there are more efficient alternatives (''.join, itertools.chain, set.unions, 
heapq.merge), but it's nice to have a recipe that saves you the trouble of 
writing special-case algorithms at the cost of a log factor that's often 
ignorable.

[issue46857] Python leaks one reference at exit on Windows

That's smart! Thanks for sharing. It may help to identify future leaks.

Py_TRACE_REFS defined)

Ah, maybe testing with Py_TRACE_REFS shows more bugs. I didn't try 
Py_TRACE_REFS recently. Well, if someone finds why it's becoming negative, a 
fix would be welcomed :-)

PEP 587 introduced PyStatus to Python startup code which let the

open a graphical popup rather than killing the process with SIGABRT 
(Py_FatalError() behavior) which might be more user friendly :-D Or just log 
the error.

Oops, that's a lot! Nicely spotted! Yeah, it's perfectly fine to allocate a 
temporary array on the heap memory. There is no need to micro-optimize this 
function.

Maybe the code was written when NGROUPS_MAX was way smaller (64?).

[issue28824] os.environ should preserve the case of the OS keys ?

[benrg]

benrg  added the comment:

This issue should be marked dependent on issue 43702 or issue 46862, since 
fixing it could break third-party code unless they're fixed first.


> Given 'nt.environ' is available without case remapping, I think that's the 
> best workaround.

Right now, it's not a good workaround because it contains the environment at 
the time the interpreter was started, not the current environment. On Posix, 
_Environ takes a reference to posix.environ and uses it directly, so it does 
get updated. On Windows, _Environ gets a rewritten dictionary and nt.environ is 
just a space-wasting attractive nuisance. I think it should be replaced with 
getenviron() which builds a dict from the environment block each time it's 
called. But posix.environ is documented (though nt.environ isn't), so maybe not.


> class _CaseInsensitiveString(str):

I think there should be a public class like this. It could be useful to 
email.message.Message and its clients like urllib. They currently store headers 
in a list and every operation is O(n).

The semantics are tricky. As written, it violates the requirement that equal 
objects have equal hashes. To fix that, you'd have to make every CIS compare 
unequal to every str. At that point, it probably shouldn't be a str subclass, 
which also has the advantage that it's not limited to strings. It can be a 
generic compare-by-key wrapper.

With all those links this is very hard to read. Please try to format
your mails in a way that makes them easy to follow.

[...][

Nope.

No. A grammar specifies how to parse the text, it doesn't say anything
about the types of these expressions (especially not in a dynamically
typed language like python). 

> *Where did I, or the language reference, go wrong?*

First, you neglected the difference between parsing an expression and
evaluating it.

Secondly, you didn't see the way out. 

For example, let's parse the expression

«f(1+2, 3)»

Can this be a call?

To confirm this, is has to match 

call ::=  primary "(" [argument_list [","] | comprehension] 
")"

which looks plausible, so let's dive in:

primary ::=  atom | attributeref | subscription | slicing | call

atom  ::=  identifier | literal | enclosure

identifier   ::=  xid_start xid_continue*

«f» is an identier which is an atom which is a primary.

Good so far. Now for the argument-list:

argument_list::=  positional_arguments ["," starred_and_keywords] 
...

positional_arguments ::=  positional_item ("," positional_item)*

We have two comma-separated items, good so far. Check «1+2» first

positional_item  ::=  assignment_expression | "*" expression

assignment_expression ::=  [identifier ":="] expression

expression ::=  conditional_expression | lambda_expr

conditional_expression ::=  or_test ["if" or_test "else" expression]

or_test  ::=  and_test | or_test "or" and_test

and_test ::=  not_test | and_test "and" not_test

not_test ::=  comparison | "not" not_test

comparison::=  or_expr (comp_operator or_expr)*

or_expr  ::=  xor_expr | or_expr "|" xor_expr

xor_expr ::=  and_expr | xor_expr "^" and_expr

and_expr ::=  shift_expr | and_expr "&" shift_expr

shift_expr ::=  a_expr | shift_expr ("<<" | ">>") a_expr

a_expr ::=  m_expr | a_expr "+" m_expr | a_expr "-" m_expr

Oof. That was a deep recursion, but we finally found a «+». 
So 1 must be an a_expr and 2 an m_expr. Actually recursing once more reveals
that both can be m_expr:

m_expr ::=  u_expr | m_expr "*" u_expr | m_expr "@" m_expr | ...

u_expr ::=  power | "-" u_expr | "+" u_expr | "~" u_expr

power ::=  (await_expr | primary) ["**" u_expr]

primary ::=  atom | attributeref | subscription | slicing | call

atom  ::=  identifier | literal | enclosure

literal ::=  stringliteral | bytesliteral | integer | floatnumber | 
imagnumber

Ok, they are both integer. 

Then we do basically the same for the second argument and we arrive at
the parse tree:

[warning: fixed width font required]

call

[issue46863] Python 3.10 OpenSSL Configuration Issues

[Adam]

Adam  added the comment:

Yes agreed, it may well be a Pyenv issue. Interestingly we can demonstrate that 
the global OpenSSL crypto policies is respected with the 3.9.10 version, 
through adjusting the policy. The ssl error occurs with the default policy 
setting and is resolved with the legacy policy setting. With 3.10.2 this is no 
longer the case. I can’t see any obvious changes to the build recipe that would 
cause this.

[issue46863] Python 3.10 OpenSSL Configuration Issues

[Christian Heimes]

Christian Heimes  added the comment:

This is a pyenv issue, not a Python issue. Custom builds of OpenSSL typically 
do not and cannot use global settings like crypto policies. They are missing 
distro downstream patches and use different config files.

[issue46849] Memory problems detected using Valgrind

[tongxiaoge]

tongxiaoge  added the comment:

The latest version is also problematic (Python 3.11.0a5). The above is the 
output stack information. Here are the steps to reproduce:

1. iotop -b -n 10 &

2. valgrind --leak-check=full /usr/sbin/iotop -b -n 5 > iotop_ test

[issue46863] Python 3.10 OpenSSL Configuration Issues

[Adam]

Adam  added the comment:

I found the Python build recipes and Pyenv does appear to install OpenSSL from 
source. The only difference I can see, aside from the Python version, is an 
update on the OpenSSL versions; openssl-1.1.1l (3.9.10) to openssl-1.1.1k 
(3.10.2). The OpenSSL release notes do not appear to suggest anything relevant.

Topics are a rarely used feature of the mailman mailing list software.
The administrator can configure topics and regular expression to
recognize them. Then mailman will scan each message it received to
assign one or more topics to it. As far as I know I have never been on a
mailinglist where the administrator had configured topics. It seems like
one of those features that seemed like a good idea to the developers but
aren't really used by anyone in practice.

[issue46864] Deprecate ob_shash in BytesObject

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

I think it is a legacy of Python 2. Attributes and variable names are Unicode 
strings in Python 3, so the main reason of this optimization is no longer 
relevant.

But some programs can still work with encoded bytes instead of strings. In 
particular os.environ and os.environb are implemented as dict of bytes on 
non-Windows.

That actually checks whether the browser is in offline mode. You can set
this mode (in Firefox at least) via File -> Work offline. The browser
will also monitor network interfaces and switch to offline mode if none
(except loopback) are up. But fundamentally it's about the state of the
browser ("... must return false if the user agent will not contact the
network ...") not about whether your computer has "internet access" in
any meaningful sense.

[issue46863] Python 3.10 OpenSSL Configuration Issues

[Adam]

Adam  added the comment:

Thanks for the quick reply. On both Ubuntu and Centos, I’m installing Python 
using Pyenv, testing with 3.9.10 and 3.10.2. Pyenv provides a verbose install 
flag, I can rebuild the Python versions and review the build commands, if 
helpful? I’m testing with clean Linux distributions and I believe there is only 
one OpenSSL installed and available. I don’t know if it’s possible to gain more 
details from the Python ssl module to confirm? I did confirm the OpenSSL 
versions aligns using ssl.OPENSSL_VERSION.

Command: pyenv install 3.10.2 --verbose

[issue46866] bytes class extension with slices

[Sec]

New submission from Sec :

When trying to extend the builtin bytes class, slices fall back to the builtin 
class.

```
class my_bytes(bytes):
  def dummy(self):
print("dummy called")


x=my_bytes.fromhex("c0de c0de")
print(x.__class__)

print(x[1:].__class__)

x.__class__ returns  as expected.

But x[1:].__class__ returns

[issue46845] dict: Use smaller entry for Unicode-key only dict.

[Inada Naoki]

Inada Naoki  added the comment:

In most case, first PyDict_SetItem decides which format should be used.

But _PyDict_NewPresized() can be a problem. It creates a hash table before 
inserting the first key, when 5 < (expected size) < 87382.

In CPython code base, _PyDict_NewPresized() is called from three places:

1. call.c: Building kwargs dict -- all key should be Unicode.
2. ceval.c: BUILD_MAP and BUILD_CONST_KEY_MAP -- there is no guarantee that all 
keys are Unicode.


Current pull request assumes the dict keys are unicode-only key. So building 
dict from non-Unicode keys become slower.

```
$ ./python -m pyperf timeit --compare-to ../cpython/python -- '{(1,2):3, 
(4,5):6, (7,8):9, (10,11):12, (13,14):15, (16,17):18}'
/home/inada-n/work/python/cpython/python: . 233 ns +- 1 ns
/home/inada-n/work/python/dict-compact/python: . 328 ns +- 
6 ns

Mean +- std dev: [/home/inada-n/work/python/cpython/python] 233 ns +- 1 ns -> 
[/home/inada-n/work/python/dict-compact/python] 328 ns +- 6 ns: 1.41x slower
```

There are some approaches to fix this problem:

1. Don't use _PyDict_NewPresized() in BUILD_MAP, BUILD_CONST_KEY_MAP

```
$ ./python -m pyperf timeit --compare-to ../cpython/python -- '{(1,2):3, 
(4,5):6, (7,8):9, (10,11):12, (13,14):15, (16,17):18}'
/home/inada-n/work/python/cpython/python: . 233 ns +- 1 ns
/home/inada-n/work/python/dict-compact/python: . 276 ns +- 
1 ns

Mean +- std dev: [/home/inada-n/work/python/cpython/python] 233 ns +- 1 ns -> 
[/home/inada-n/work/python/dict-compact/python] 276 ns +- 1 ns: 1.18x slower
```

I think this performance regression is acceptable level.

2. Add an argument `unicode` to _PyDict_NewPresized(). -- Breaks some 3rd party 
codes using internal APIs.
3. Add a new internal C API such that _PyDict_NewPresizedUnicodeKey(). -- Most 
conservative.
4. Add a new internal C API that creates dict form keys and values for extreme 
performance, like this:

// Create a new dict from keys and values.
// Items are received as `{keys[i*keys_offset]: values[i*values_offset] for i 
in range(length)}`.
// When distinct=1, this function skips checking duplicated keys.
// So pass distinct=1 unless you can guarantee that there is no duplicated keys.
PyObject *
PyDict_FromKeysAndValues(PyObject **keys, Py_ssize_t keys_offset, PyObject 
**values, Py_ssize_t values_offset, Py_ssize_t lenghh, int distincit)
{
}

How did you build Python 3.10? Neither CentOS 8 nor Ubuntu 20.04 come with 
Python 3.10. Does your build of Python use system's OpenSSL build?

[issue46865] *() Invalid Syntax: iterable unpacking of empty tuple

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

See the grammar. 
https://docs.python.org/3/reference/expressions.html#conditional-expressions


conditional_expression ::=  or_test ["if" or_test "else" expression]
expression ::=  conditional_expression | lambda_expr

`*()` is not an expression. It is either a starred_item (which can be a part of 
starred_list or a starred_expression), or a positional_item or a 
starred_and_keywords which are parts of an argument_list. None of them are 
expressions.

`foo(*(stri,) if stri else x)` is interpreted as `foo(*((stri,) if stri else 
x))` if x is an expression. But `*()` is not an expression, thus a syntax error.

[issue46865] *() Invalid Syntax: iterable unpacking of empty tuple

[Robert Spralja]

New submission from Robert Spralja :

`
>>> def foo(num=1):
... return num
...
>>> foo(*(bool,) is bool else *())
  File "", line 1
foo(*(bool,) is bool else *())
 ^
SyntaxError: invalid syntax
>>> foo(*(bool,) if bool else *())
  File "", line 1
foo(*(bool,) if bool else *())
  ^
SyntaxError: invalid syntax
>>> def foo(num=1):
... return num
...
>>> stri = ''
>>> foo(*(stri,) if stri else *())
  File "", line 1
foo(*(stri,) if stri else *())
  ^
SyntaxError: invalid syntax
>>> foo(*((stri,) if stri else ()))
1
>>>
`

Iterable unpacking of empty tuple seems to not work in one example but does in 
another.

[issue46864] Deprecate ob_shash in BytesObject

[Inada Naoki]

New submission from Inada Naoki :

Code objects have more and more bytes attributes for now.
To reduce the RAM by code, I want to remove ob_shash (cached hash value) from 
bytes object.

Sets and dicts have own hash cache.
Unless checking same bytes object against dicts/sets many times, this don't 
cause big performance loss.

[issue46833] Windows installer is unclear and has redundant settings

[Christian Buhtz]

Christian Buhtz  added the comment:

Dear Steve,
thanks for your feedback. I did not understand all details of your design 
decisions but I am OK with that.

Variant A is fine for me, too. The important to points of A for me are 1) that 
the checkboxes on page 1 are moved up directly under the "Install Now" to make 
clear where they belong to and 2) the (easier to understand) separation between 
interpreter- (page2) and launcher-settings (page3).

My apologize but I am not able to create PRs/patches. I am not familiar with 
your development environment and not able to invest time to learn it because in 
the feature it does not seems like I will create more patches for something 
because I do not have the expertise for a python interpreter.

But I understand that is a question of resources. If there are currently now 
resources I would recommend to keep this ticket open.
