[issue35431] Add a function for computing binomial coefficients to the math module

[Mark Dickinson]

Mark Dickinson  added the comment:

@David Ratcliffe

> the sum of the first n positive integers is binomial(n+1, 2), and the formula 
> should still work if n is zero.

I agree that's a convincing use-case.

Can you think of any practical uses for allowing negative `k`? I can't.

He did, at a high level. in the original mail:

"If code objects supported the buffer protocol it would be possible to load
 code from a memory mapped file which is shared across all of the processes."


It is not very detailed, but gives the rationale.  I assumed that the
new shared memory support would be used, but it would be nice to hear
more details.

[issue37131] all(range()...)) is needlessley slow

[Terji]

New submission from Terji :

Checking if a range's items are ll truthy can be done y checking if 0 the range 
contains 0, however currently Python iterates over the range, making the 
operation slower than needed.

>>> rng = range(1, 1_000_000)
>>> timeit all(rng)
19.9 ms ± 599 µs per loop

If the all function could special case range, this could be like made fast like 
this:

if isinstance(obj, range):
if 0 in obj:
return False
return True

[issue37131] all(range()...)) is needlessley slow

[Steven D'Aprano]

Steven D'Aprano  added the comment:

Why should ``all()`` special case ``range``? Apart from showing off benchmarks, 
what's the point?

Should ``any()`` also special case it? How about other lazy sequences and 
computed iterables, such as itertools.count objects, itertools.cycle objects, 
itertools.repeat objects, etc? How many special cases do we want?

Personally, I don't *necessarily* oppose special-casing types, but it breaks 
the independence of types, and couples the all() function and the range() 
function. To be worth doing, we should get some practical benefit out of it. It 
isn't clear what that benefit is.

Don't get me wrong, its not like I *want* all(range(1, 10**10)) to be slow. But 
nor do I want to couple the all() function to the range function and complicate 
the implementation if there is no corresponding benefit. After all, testing 
with all() is fundamentally an O(N) worst case operation so anything better 
than that is a nice surprise.

If there were special dunders __all__ and __any__ it would be easy to 
encapsulate this behaviour inside the range objects themselves, and neither 
any() nor all() would need to know anything about range objects.

[Terji]

Terji  added the comment:

Mostly to avoid silly mistakes, and the overhead of doing it would be very 
small, so a very small trade-off.

>> Should ``any()`` also special case it?

No, ``any()``takes at most two iterations to check truthiness in a ``range()``, 
so that's wouldn't be needed.

>> How about other lazy sequences and computed iterables, such as 
>> itertools.count objects, itertools.cycle objects, itertools.repeat objects,

No, I wouldn't propose that. The argument would be that those are 
iterators/generators while ``range()`` is special-cased built-in sequence with 
known properties.

[issue17576] PyNumber_Index() is not int-subclass friendly (or operator.index() docos lie)

[Mark Dickinson]

Mark Dickinson  added the comment:

I'm working on a PR that finally changes the DeprecationWarnings that Serhiy 
introduced to TypeErrors; I think that should be acceptable, four Python 
versions and some years later. With that PR:

- int will always return something of exact type `int` (or raise)
- operator.index will always return something of exact type `int` (or raise)
- PyNumber_Index will always use `__index__` for int subclasses, so this should 
fix the issue that Barry originally reported (mismatch between 
`obj.__index__()` and `operator.index(obj)`).

This sounds very interesting, and more general. It would be useful for e.g. 
numpy arrays, where ``all(arr)`` currently is slower than ``arr.all()``. Don't 
know it there's a reason it wasn't implemented this way originally?

Its not just the overhead, its the coupling between two chunks of code 
which should be independent.

[issue37132] Add a module for integer related math functions

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

The math module contains as function for floating-point numbers, as wells as 
functions for integer only numbers: factorial(), gcd(). Yet few integer 
specific functions was added in 3.8: isqrt(), perm(), comb().

The proposed PR adds the new imath module, adds into it old functions 
factorial() and gcd() and moves new functions. It also adds two additional 
functions: as_integer_ratio() and ilog2().

There are plans for adding more integer functions: divide_and_round(), 
is_prime(), primes(), but the work in progress.

[issue32052] Provide access to buffer of asyncio.StreamReader

[Andrew Svetlov]

Andrew Svetlov  added the comment:

Closing.
Brief:
1. Access to an internal buffer is not an option.
2. Pushing data back to stream after fetching is not an option too: it kills 
almost any possible optimization and makes code overcomplicated. aiohttp used 
to have "unread_data()" API but we deprecated it and going to remove the method 
entirely. A wrapper around the stream with puback functionality is an option 
though unless it doesn't touch underlying stream implementation.
3. Extending a set of reader operations is a good idea, please make a separate 
issue with a concrete proposal if needed.

[issue37132] Add a module for integer related math functions

[Mark Dickinson]

Mark Dickinson  added the comment:

Some questions:

- What's the plan for the existing functions `math.gcd` and `math.factorial`? 
Do they eventually get deprecated, or do we keep `gcd` and `factorial` in both 
`math` and `imath`?

- Does PEP 399 apply here? If so, we'll need a pure Python version as well as a 
C version

- Should `imath.isqrt` be renamed to `imath.sqrt`?

- What's the actual benefit of this separation?

This feels like a really big change to be making a day before feature freeze; 
I'm not convinced that we don't need a PEP for this. How bad would it be if we 
have to defer until 3.9?

[issue17576] PyNumber_Index() is not int-subclass friendly (or operator.index() docos lie)

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

I am not sure that raising an error is the best option. We can just convert an 
integer subclass to an exact int using _PyLong_Copy().

I am not sure that converting to an exact int in low-level C API functions is 
the best option. In many cases we use only the content of the resulting object 
ignoring its type (when convert it to the C integer or float, to bytes array, 
to new instance of int subclass). Creating a new exact int is a waste of time.

This is why I withdrawn my patches and this issue is still open.

On futher reflection, I don't think it should. It's a different function, so 
it's not like comparing `math.sqrt` and `cmath.sqrt`.

One more: I suggest renaming the new function `ilog` to `ilog2`, for 
consistency with `math.log` versus `math.log2`.

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

> What's the plan for the existing functions `math.gcd` and `math.factorial`?

I think they should eventually get deprecated, but with long term of 
deprecation. Deprecation warning should be added only when imath versions are 
already available in older Python versions.

But they can be also kept as pure aliases for very long time.

> Does PEP 399 apply here?

There were no Python implementations when these functions was in the math 
module. But there are Python implementations for all these functions (used in 
tests or as predecessors), so it is not hard to add them in the stdlib. Easier 
that to implement math.sin() on Python from scratch.

> Should `imath.isqrt` be renamed to `imath.sqrt`?

I considered this idea and do not have answer.

> What's the actual benefit of this separation?

Currently math becomes a mix of very different functions. Separation will help 
to keep it simpler (from user and implementation sides). It also adds a place 
for landing new integer specific functions which are too specific to add them 
into the math module or into the int class.

[issue37132] Add a module for integer related math functions

[Mark Dickinson]

Mark Dickinson  added the comment:

I think the new `as_integer_ratio` also needs discussion: it was agreed at some 
point in the past to add `as_integer_ratio` *methods* on all numeric built-in 
types, and there's a PR for that. Adding `as_integer_ratio` as a new function 
too seems like two ways to do it.

Please can we defer to 3.9? There just isn't time for the design discussions 
that are needed, and I'd personally rather see the first version of the `imath` 
module be somewhat complete, with `is_prime` and `primes` already.

I do realise that from the perspective of adding an `imath` module, the 
accumulation of integer-based functions in the `math` module is something of a 
wart that we're making worse in 3.8, but I don't think rushing in this change 
is the solution.

Radical suggestion: should we consider delaying the inclusions of `comb`, 
`perm` and `isqrt` in the math module so that we can do this properly for 3.9?

[issue37132] Add a module for integer related math functions

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Actually it was ilog2. There was just an error in the documentation.

Currently we have two ways to represent the number as an integer ratio. The 
official way is two properties numerator and denominator, every number should 
have them. And some concrete numeric types have the as_integer_ratio() method 
which returns both values. Rather of adding as_integer_ratio() to all other 
numeric types I propose to add a helper function which uses either the 
as_integer_ratio() method if available, or  the numerator and denominator 
properties. Currently any code that uses the as_integer_ratio() method should 
implement a fallback to numerator and denominator. With 
imath.as_integer_ratio() it can just use this function.

> Radical suggestion: should we consider delaying the inclusions of `comb`, 
> `perm` and `isqrt` in the math module so that we can do this properly for 3.9?

I like it. I suggest to delay also adding the int.as_integer_ratio() method. 
Currently it does not help because there are other numeric methods without the 
as_integer_ratio() method.

[issue37132] Add a module for integer related math functions

[Mark Dickinson]

Mark Dickinson  added the comment:

I'm pretty much out of core-dev cycles for this weekend; I'm happy to review 
GH-13741, but won't have time to do so before next weekend.

I'm overall -0 on this change; there's a minor benefit in the separation, but 
for me it's outweighted by the duplication of `gcd` and `factorial` (or in the 
case of `gcd`, triplication, since it's also in the `fractions` module).

I'm out of time, so I'll be brief, but if this does go into 3.8, here are my 
thoughts:

- please remove the imath.as_integer_ratio function; it needs more discussion, 
and it has quite a different character from the other functions; it's not at 
all clear to me that it belongs. We might end up putting it back in eventually, 
but it needs discussion first, and we don't have time for that discussion 
before feature freeze.
- please add the pure Python version of imath that PEP 399 requires, or get 
Brett's confirmation that PEP 399 doesn't apply in this case.
- please get agreement from one (preferably both) of Tim and Raymond

Raymond, Tim: thoughts?

Lysandros Nikolaou  added the comment:

This can be most likely be closed. In the last days I had some unrelated 
problems with my mac and had to do a full format. After reinstalling macOS the 
problem went away, so it must have been something specific to my previous state

[issue35431] Add a function for computing binomial coefficients to the math module

[Tim Peters]

Tim Peters  added the comment:

I'm not convinced, although I agree relaxing k <= n is less damaging than 
relaxing k >= 0.

Python isn't aimed at mathematicians (although some 3rd-party packages 
certainly are, and they're free to define things however they like).  We have 
to trade off convenience for experts in edge cases against the likelihood that 
an ordinary user is making a mistake.

For example, that's why, despite that Python supports complex numbers, 
math.sqrt(-1) raises ValueError.  For _most_ users, trying that was probably an 
error in their logic that led to the argument being negative.  Experts can use 
cmath.sqrt() instead.

Ordinary users think comb(n, k) is the value of n!//(k!*(n-k)!), and as far as 
they're concerned factorial is only defined for non-negative integers.  0 <= k 
<= n follows from that.  (Indeed, the current docs for `comb()` _define_ the 
result via the factorial expression.)

And ordinary users think of the sum of the first n integers as "number of terms 
times the average", or memorize directly that the answer is n*(n+1)/2.  That 
works fine for n=0.  Only an expert thinks of it as `comb(n+1, 2)`.

So I would still rather enforce 0 <= k <= n at the start, and relax it later 
only if there's significant demand.  In going on three decades of using Python 
and having written my own `comb()` at least a dozen times, I've never found 
that constraint limiting, and enforcing it _has_ caught errors in my code.

In typeperf_output text with description of the error:
'\r\nВыполняется выход, подождите... \r\nОшибка:

Translation on English is "Exiting, wait... Error: Counters are not specified."

Is it possible to check if the counters are found in advance?

[issue37134] Use PEP570 syntax in the documentation

[Pablo Galindo Salgado]

New submission from Pablo Galindo Salgado :

In the documentation, there are a lot of mismatches regarding function and 
method signatures that use positional-only arguments with respect to the 
docstrings (that properly use PEP570 syntax for documenting positional-only 
parameters).

Not that the official syntax for positional-only parameters is accepted (the 
"/"), the documentation needs to be updated to reflect positional-only 
parameters in the functions and methods that use them as covered in the PEP 
document.

[issue37132] Add a module for integer related math functions

[Raymond Hettinger]

Raymond Hettinger  added the comment:

-1 I prefer these functions get left in the regular math module and just 
organize the docs to separate out integer functions.  Additional namespacing 
creates cognitive load and creates a findability problem.

Also, I really don't want gcd() to be moved yet again.

[issue37132] Add a module for integer related math functions

[Raymond Hettinger]

Raymond Hettinger  added the comment:

After the beta feature freeze, I'll write up an edit the math module docs that 
makes in easier to find functions (by splitting out a section of the docs for 
these functions and by creating a summary link table at the top like we do for 
builtins).  I really don't want a separate module for this and think that would 
work against the needs of usres.

[issue37124] test_msilib is potentially leaking references and memory blocks

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

The leak is because creating a 'msilib.Directory' adds an entry on a global 
variable '_directories', therefore leaking.

My first PR will make sure the _directories is cleared out after the test to 
stop the leak, but it seems to me that the variable is unused.

@Steve, could you confirm that there is still a reason for the 
msilib._directories?

[issue32912] Raise non-silent warning for invalid escape sequences

[Raymond Hettinger]

Raymond Hettinger  added the comment:

I'm seeing these warnings pop up from time to time with various third party 
packages (such as pyparsing which is invoked by ensurepip).

Am wondering whether this should be deferred for another version or so until be 
have good confidence that the major third party packages have all had a chance 
to adapt.  Otherwise, this will mostly be noise for end-users.  Also, it gets 
in the way of the end-user strategy of "backslash anything that looks special" 
as preferred over "remember exactly which things are special".  This may be a 
case of "the cure is worse than the disease".

[issue37080] Cannot compile Python3.7.3 on Alt-F (ARM)

[Jarl Gullberg]

Jarl Gullberg  added the comment:

That's correct, CPython. I'm not sure if MicroPython would fit the bill for
me, since this system is a full-blown Linux system.

After some more testing, I can add that the same issue crops up when attempting

[issue35621] asyncio.create_subprocess_exec() only works with main event loop

[Andrew Svetlov]

Andrew Svetlov  added the comment:

Thanks for the report!

The failure depends on tests order execution (maybe you use -jN flag?).
Before default child watcher was SafeChildWatcher, not it is 
ThreaderChildWather.
The watcher is a global variable (a property of global event loop policy).

The failed test doesn't make sense for default ThreadChildWatcher but still 
valuable for old default SafeChildWatcher.
I've changed the test to use SafeChildWatcher explicitly.

See https://github.com/python/cpython/pull/13754 for the fix

[issue20602] sys.flags and sys.float_info disappear at shutdown

[STINNER Victor]

STINNER Victor  added the comment:

Honestly, I'm not sure that this issue is really a major bug. I don't think 
that it's worth it to backport the change. It's more a subtle change in Python 
finalization which is super fragile code. I prefer to only change the master 
branch, so I close the issue.
