[issue46825] slow matching on regular expression

[Heran Yang]

New submission from Heran Yang :

I'm using `re.fullmatch` to match a string that only contains 0 and 1. The 
regular expression is: (0+|1(01*0)*1)+

It runs rather slow with Python 3.7, but when I try using regex in C++, with 
std::regex_constants::__polynomial, it works well.

Would someone take a look at it? Thx.

tornado: 
https://github.com/tornadoweb/tornado/issues/3113#issuecomment-1041019287

I think it would be better to use this AI_NUMERICHOST | AI_NUMERICSERV

[issue46725] Unpacking without parentheses is allowed since 3.9

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

What happened is that the new grammar using the PEG parser used the equivalent 
of starred_testlist instead of testlist for the iterable list of for statements.

The only extra thing allowed is starred elements, that are interpreted as if 
you are building a tuple without parentheses.

[issue46818] Proper way to inherit from collections.abc.Coroutine

[Andrew Svetlov]

Andrew Svetlov  added the comment:

> Are you suggesting that I need to just inherit from Awaitable? 

Yes. Awaitable is a very base protocol, Coroutine is an implementation.

`__await__` returns a generator that is used by Python internals as if `yield 
from awaitable.__await__()` was called.  asyncio never sends data back to the 
generator but other async frameworks can do it.

`send()`/`close()`/`throw()` coroutine methods are never used now IFAIK.  The 
current implementation calls these methods at the C level without using 
Python-exposed names. Performance matters.
These methods can be still used in very rare cases, e.g. when explicit Python 
`yield from custom_coro.__await__()` is used.

[issue46798] xml.etree.ElementTree: get() doesn't return default value, always ATTLIST value

[Stefan Behnel]

Stefan Behnel  added the comment:

The question here is simply, which is considered more important: the default 
provided by the document, or the default provided by Python. I don't think it's 
a clear choice, but the way it is now does not seem unreasonable. Changing it 
would mean deliberate breakage of existing code that relies on the existing 
behaviour, and I do not see a reason to do that.

The expression is a repeated alternative where the first alternative is a 
repeat. Repeated repeats can result in a lot of attempts and backtracking and 
should be avoided.

Try this instead:

(0|1(01*0)*1)+

[issue46822] test_create_server_ssl_over_ssl times out on some systems

[Steve Dower]

Steve Dower  added the comment:

Looks like my issue is actually related to the timeouts added in issue44011.

I'm guessing it's an SSL shutdown timeout, because those are notoriously weird 
on Windows/OpenSSL.

The timeout is now 30s, but the test aborts after 10s. If I increase the test 
timeout to 50s, it passes reliably.

However, if I pass ssl_shutdown_timeout to the protocol created in the test 
(which I think is the right place?), it fails with a timeout somewhere else.

So my guess is that my system (VM in a somewhat protected network) is 
legitimately taking that long to shut down the connection? And so the test 
timeout ought to be increased?

[issue46822] test_create_server_ssl_over_ssl times out on some systems

[Steve Dower]

Steve Dower  added the comment:

In fact, I only have to increase the test timeout to 15s to get it to pass 
reliably.

I don't see any reason the test should time out quicker than the operations 
it's testing though, right? So set it to 30s?

[issue46806] Overlapping PYTHONPATH may cause import already imported module

[Eric Snow]

Eric Snow  added the comment:

When you run a Python script, the directory the script is in is automatically 
added to the beginning of sys.path.  This is the fundamental issue you've run 
into.

Basically, "src.common_object" is imported relative to the "src" that was 
imported relative to that automatically added sys.path entry.  However, 
"common_object" is a distinct module imported relative to the sys.path entry 
you explicitly added.

In general, adding a package's directory to sys.path is a bad idea.

[issue46806] Overlapping PYTHONPATH may cause import already imported module

[Eric Snow]

Eric Snow  added the comment:

Here is more detail on what happens when "from src import user_1, user_2, 
user_3" is executed in main.py:

1. the "src" module is imported
   a. not found in sys.modules
   b. file found on a sys.path entry (the directory main.py is in)
   c. the "src" module is created with __path__ set to the src directory
   d. the module is added to sys.modules
   e. src/__init__.py is executed
2. the "src.user_1" module is imported
   a. not found in sys.modules
   b. file found relative to src.__path__
   c. module created
   d. added to sys.modules
   e. executed
3. "from .common_object import OBJECT" is resolved to "from src.common_object 
import OBJECT"
4. "src.common_object" is imported (see 2)
5. src.common_object.OBJECT is created
6. "src.user_2" is imported (see 2)
7. "src.common_object" is already found in sys.modules and used
8. "src.user_3" is imported (see 2)
9. "common_object" is imported
   a. not found in sys.modules
   b. file found on a sys.path entry (the one you added in main.py)
   c. module created
   d. added to sys.modules
   e. executed
10. common_object.OBJECT is created

So the module created at (4) is different than the one at (9), even though they 
are imported from the same file.  Consequently, the OBJECT in each is likewise 
distinct.

[issue46819] Add an Error / Exception / Warning when contextlib.suppress() is entered with no specified exception(s) to suppress

[Zachary Ware]

Zachary Ware  added the comment:

But `suppress` takes varargs; from `suppress`'s perspective, there is no 
difference between `suppress()` and `l=[];suppress(*l)`.  There would be a 
difference at the AST level, but trying to find it within `suppress` to issue a 
warning seems unfeasible.  Certainly possible for a linter, though :)

Ok thanks. Looks like the warning in flake8-bugbear is the right place then, 
unfortunately.

And just to be sure:

> Note that suppress without arguments corresponds to "except" and isinstance() 
> with empty tuple.

Are you saying that `contextlib.suppress()` should effectively `except 
BaseException` (cause this is not the behavior from my tests) and suppress all 
or suppress nothing? I believe the empty tuple makes it except nothing?

```python

No, I say that

or

If you want to suppress all exceptions (it is not very clever idea), use 
suppress(BaseException).

[issue46828] math.prod can return integers (contradicts doc)

[Neil Webber]

New submission from Neil Webber :

The math module documentation says:

   Except when explicitly noted otherwise, all return values are floats.

But this code returns an integer:

   from math import prod; prod((1,2,3))

Doc should "explicitly note otherwise" here, I imagine. The issue being wanting 
to know that the result on all-integer input will be an exact (integer) value 
not a floating value.

[issue46829] Confusing CancelError message if multiple cancellations are scheduled

[Andrew Svetlov]

New submission from Andrew Svetlov :

Suppose multiple `task.cancel(msg)` with different messages are called on the 
same event loop iteration.

What message (`cancel_exc.args[0]`) should be sent on the next loop iteration?

As of Python 3.10 it is the message from the *last* `task.cancel(msg)` call. 
The main branch changed it to the *first* message (it is a subject for 
discussion still).
Both choices are equally bad. The order of tasks execution at the same loop 
iteration is weak and depends on very many circumstances. Effectively, 
first-cancelled-message and last-cancelled-message are equal to random-message.

This makes use of cancellation message not robust: a task can be cancelled by 
many sources, task-groups adds even more mess.

Guido van Rossum suggested that messages should be collected in a list and 
raised altogether. There is a possibility to do it in a backward-compatible 
way: construct the exception as `CancelledError(last_msg, tuple(msg_list))`. 
args[0] is args[1][-1]. Weird but works.

`.cancel()` should add `None` to the list of cancelled messages.
The message list should be cleared when a new CancelledError is constructed and 
thrown into cancelling task.

Working with exc.args[0] / exc.args[1] is tedious and error-prone. I propose 
adding `exc.msgs` property. Not sure if the last added message is worth a 
separate attribute, a robust code should not rely on messages order as I 
described above.

The single message is not very useful but a list of messages can be used in 
timeouts implementation as cancellation count alternative.

I don't have a strong preference now but want to carefully discuss possible 
opportunities before making the final decision.

[issue45100] Improve help() by making typing.overload() information accessible at runtime

[Alex Waygood]

Alex Waygood  added the comment:

I'd dearly like better introspection tools for functions decorated with 
@overload, but I'd rather have a solution where:

- inspect.signature doesn't have to import typing. That doesn't feel worth it 
for users who aren't using typing.overload, but inspect.signature would have to 
import typing whether or not @overload was being used, in order to *check* 
whether @overload was being used.
- The solution could be reused by, and generalised to, other kinds of functions 
that have multiple signatures.

If we create an __overloads__ dunder that stored the signatures of 
multi-signature functions, as Raymond suggests, inspect.signature could check 
that dunder to examine whether the function is a multi-dispatch signature, and 
change its representation of the function accordingly. This kind of solution 
could be easily reused by other parts of the stdlib, like 
@functools.singledispatch, and by third-party packages such as plum-dispatch, 
multipledispatch, and Nikita's dry-python/classes library.

So, while it would undoubtedly be more complex to implement, I much prefer 
Raymond's suggested solution.

[issue46829] Confusing CancelError message if multiple cancellations are scheduled

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

What about `CancelledError(*msg_list)` or 
`CancelledError(*reversed(msg_list))`? It is backward compatible and all 
messages are uniformely represented.

[issue46829] Confusing CancelError message if multiple cancellations are scheduled

[Guido van Rossum]

Guido van Rossum  added the comment:

I would like to go on record (again) as preferring to get rid of the 
cancel-message parameter altogether. Let's deprecate it. When we initially 
designed things without a cancel message we did it on purpose -- "cancellation" 
is a single flag, not a collection of data.

[issue43119] asyncio.Queue.put never yields if the queue is unbounded

[Andrew Svetlov]

Andrew Svetlov  added the comment:

Sorry, that's how asyncio works: it never switches to another task if `await 
...` doesn't need to wait for something actually.

Adding `await asyncio.sleep(0)` to every call decreases performance.

Deprecation is a good answer. 
Let's not forget to apply it to 3.11 then.
