[issue44043] 3.10 b1 armhf Bus Error in hashlib test: test_gil

[Anthony Sottile]

New submission from Anthony Sottile :

terribly sorry, I don't have much information to go off on this other than the 
build logs from deadsnakes.

I retried this build twice and it seems it consistently fails in this position:

Re: uninstall

[Chris Nyland]

So it seems counter intuitive but you might also have luck just
reinstalling Python3.8 back over top. If the uninstall was botch then that
should put everything back in place and then you can just run the uninstall
again and see if it clears out this time. Otherwise I agree with stack
overflow you can just go in and do it manually. If you have multiple Python
installs I would recommend make sure to use the py launcher instead of
adding any of the Pythons to the Windows path. I also don't like the new
default install location in the program folders for development machines
and find that it can sometimes cause conflicts so for those machines where
I need multiple versions I still install Python on the root of the the C
drive or and additional hard drive and name the folders PythonXX_32 or 64
depending on the type of install where XX is of course the major and minor
version 36, 37, 38 etc. Then I use py -3.6 and so on to execute the
different installs from the command line.

Transistion from module to package and __init__.py

[Chris Nyland]

Hello,

I have a design question that for me primarily occurs when I have a module
that needs to transition to a package. Lets assume I have module that
services a database. Initially the module just has some functions to pull
data out of the database format them etc. As the project grows I add tables
some of the tables have static data or initialization data that are stored
in CSVs. I build functions that initialize the database a schema file is
now used. Now my module is still the only Python code file I have but I
have these other data files the module needs, time to make a package. So
naturally I make a package folder called database, put and empty
__init__.py, in goes my database module and all resource files. Here is
where I my primary design question comes in. As organized now as described
to import and use the package I need

from database import database

or I have to put in the init file

from database import *

Either of these still leaves a database.database namespace laying about and
to me it just seems untidy. So for a while now I have taken to converting
my module, in this example database.py, to the __init__.py of the package.
I remember reading years back that having code in the __init__.py was bad
practice but I can't remember reading for any specific reason. So then I
ask is there anything in fact wrong with this practice? I have probably a
dozen packages now that are used internal to my organization that follow
this pattern and I haven't encountered any issues. So I was hoping to get
feed back from a wider audience about if there are any issues with this
type of design that I just haven't encounter yet or find out what other
people do with this same problem.

Thanks

Chris

[issue43882] [security] urllib.parse should sanitize urls containing ASCII newline and tabs.

[Gregory P. Smith]

Gregory P. Smith  added the comment:

Both Django and Botocore issues appear to be in the category of: "depending on 
invalid data being passed through our urlsplit API so that they could look for 
it later"  Not much sympathy.  We never guaranteed we'd pass invalid data 
through.  They're depending on an implementation detail (Hyrum's law).  Invalid 
data causes other people who don't check for it problems.  There is no valid 
solution on our end within the stdlib that won't frustrate somebody.

We chose to move towards safer (undoubtedly not perfect) by default.

Instead of the patches as you see them, we could've raised an exception.  I'm 
sure that would also also have tripped up existing code depending on the 
undesirable behavior.

If one wants to reject invalid data as an application/library/framework, they 
need a validator.  The Python stdlib does not provide a URL validation API.  
I'm not convinced we would even want to (though that could be something 
issue43883 winds up providing) given how perilous that is to get right: Who's 
version of right? which set of standards? when and why? Conclusion: The web... 
such a mess.

[issue43933] Regression in python3.10 with traceback frame having lineno of -1

[Ned Batchelder]

Ned Batchelder  added the comment:

Mark, I'm not clear if the line number can still be None in some circumstances. 

With this code (from site.py in the stdlib):

545: def execsitecustomize():
546: """Run custom site specific code, if available."""
547: try:
548: try:
549: import sitecustomize
550: except ImportError as exc:
551: if exc.name == 'sitecustomize':
552: pass
553: else:
554: raise
555: except Exception as err:
556: if sys.flags.verbose:
557: sys.excepthook(*sys.exc_info())
558: else:
559: sys.stderr.write(
560: "Error in sitecustomize; set PYTHONVERBOSE for 
traceback:\n"
561: "%s: %s\n" %
562: (err.__class__.__name__, err))

I get traces with these events and line numbers:

exception 549 (ModuleNotFoundError("No module named 'sitecustomize'"))
line 550
line 551
line 552
return None

Is this what you expected?

[issue43883] Making urlparse WHATWG conformant

[Gregory P. Smith]

Gregory P. Smith  added the comment:

FWIW rather than implementing our own URL parsing at all... wrapping a library 
extracted from a compatible-license major browser (Chromium or Firefox) and 
keeping it updated would avoid disparities.

Unfortunately, I'm not sure how feasible this really is.  Do all of the API 
surfaces we must support in the stdlib for compatibility's sake with urllib 
line up with such a browser core URL parsing library?

Something to ponder.  Unlikely something we'll actually do.

[issue44042] [sqlite3] _pysqlite_connection_begin() optimisations

[Erlend Egeberg Aasland]

New submission from Erlend Egeberg Aasland :

The following optimisations can be applied to _pysqlite_connection_begin():

1. Return an int instead of a PyObject pointer

   Per now, we do Py_RETURN_NONE and Py_DECREF(result) if 
_pysqlite_connection_begin() was successful (normally the case). There's no 
reason to do this. Let's just it the C way: return -1 on error and 0 if things 
are ok.


2. Defer error checking till post sqlite3_finalize()

   Any error code returned by sqlite3_step() will also be returned by 
sqlite3_finalize() for the same statement. From the SQLite docs:
   "If the most recent evaluation of statement S failed, then 
sqlite3_finalize(S) returns the appropriate error code or extended error code."


3. Move _pysqlite_connection_begin() to Modules/_sqlite/cursor.c

   The single use is in _pysqlite_query_execute() in cursor.c. Moving it makes 
it possible for the compiler to apply more optimisations. At least so I've 
heard :)
   (As a side effect, the namespace will be cleaner.)

[issue44026] IDLE: print "Did you mean?" for AttributeError and NameError

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Pablo, unless you are suggesting rewriting IDLE's custom exception handing in 
C, I don't see how making it a single function would be an improvement.  As 
long as it is Python code, the problem is accessing the message supplement.

After reading your comment, I agree that injecting Python code into the C 
exception handling is a bad idea.  It also, I see now, not needed

run.print_exception first calls traceback.extract_tb (line 238).  The doc says 
" It is useful for alternate formatting of stack traces", which IDLE does.  
print_exception next calls the undocumented traceback.print_list, which is 
format_list + print*.  Finally, print_exception calls 
traceback.format_exception_only (line 2440), which returns a list of lines that 
is immediately printed.

So all IDLE needs is for format_exception_only to include the extra lines, 
either by default or by option.  But it just calls 
TracebackException.format_exception)only, which call a private Python-coded 
function, which can only add the lines if accessible from Python-code.

Dennis cleverly pointed out that such access is available, even if awkwardly, 
by capturing the standard excepthook outout and keeping only the missing part.  
(test.support.captured_stderr just wraps io.StringIO as a context manager.  
IDLE can borrow and edits its code.)

Dennis, would you like to prepare a PR that follows the format_exception_only 
call with something like

if isinstance(typ, (AttributeError, NameError)):
lines.extend(extract_extra_message())

and a definition of the new function?  (and a new test)?  Or perhaps better, 
replace format_exception_only with a function that gets all lines at once.

Pablo, do any other exception types have such omitted help info?  Do you have 
plans for any more?

[Raymond Hettinger]

Raymond Hettinger  added the comment:

That was my thought as well.  Perhaps that is worth a note in the docs but 
there is likely no real need to change the behavior.

[issue44041] [sqlite3] optimisation: only call sqlite3_column_count when needed

[Erlend Egeberg Aasland]

New submission from Erlend Egeberg Aasland :

Pr. now, we call sqlite3_column_count() for every iteration in the 
_pysqlite_query_execute() loop. If detect_types is set, we call it twice for 
every loop.

Suggesting to move it out of the loop and into the pysqlite_Statement object. 
In pysqlite_statement_create(), after sqlite3_prepare_v2(), if self->is_dml == 
0 we fetch the column count: self->column_count = sqlite3_column_count(). Else, 
it's 0.

[issue44037] Broad performance regression from 3.10a7 to 3.10b1 with python.org macOS binaries

Pablo just ran the same benchmarks on Arch Linux and did not observe the 
degradation, so this does seem specific to the macOS build.

[issue43192] Argparse complains argument required when default is provided

[paul j3]

paul j3  added the comment:

To a large degree the Action parameters operate independently.  That is, 
different parts of the code use the parameters for their own purposes. The 
composite behavior is a result of those individual actors, rather than some 
sort of overall coordinated plan.

First your Action is 'positional' (no flag string), and "store" type.  nargs is 
the default None.  The only extra is the default value (the default default is 
None).

_ActionsContainer._get_positional_kwargs processes such an argument, setting 
the 'required' parameter with:

# mark positional arguments as required if at least one is
# always required
if kwargs.get('nargs') not in [OPTIONAL, ZERO_OR_MORE]:
kwargs['required'] = True
if kwargs.get('nargs') == ZERO_OR_MORE and 'default' not in kwargs:
kwargs['required'] = True

At the start of parsing, all 'default' values are added to the 'args' Namespace.

If an Action is "seen", either via the appropriate flag string, or a positional 
value, it is added to the "seen_actions" list.

At the end of parsing, it iterates through all the '_actions'.  If it is not in 
the 'seen_actions' list, and is marked "required", it gets added to the 
'reqiuired_action' error list.

So even though your Action has a 'default' it is still required.  The default 
is, in effect, ignored.  The nargs value (default or not) has priority in 
setting the 'required' value.

'?/*' nargs require special handling.  This nargs requirement is satisfied by 
an empty list.  Such a positional will, in effect, always be seen. But if a 
explicit default is provided, that will over write the empty list. 

Handling defaults is inherently tricky.  But except for the special '?/*' case, 
specifying a 'default' with a positional doesn't make much sense.

[issue44037] Broad performance regression from 3.10a7 to 3.10b1 with python.org macOS binaries

[Ned Deily]

Ned Deily  added the comment:

Thanks for the report, Raymond, and for taking the time to check performance.

I am able to reliably reproduce the slowdowns in the benchmark between the 
3.10.0a7 and 3.10.0b1 versions provided by the macOS installers on python.org. 
A similar slowdown is seen on both Intel and Apple Silicon Macs running macOS 
11.3.1. Doing a quick build from source, I see no similar large differences 
between 3.10.0a7 and 3.10.0b1 on either macOS (with XC 12.5 Clang 12.0.5) or on 
a Debian Linux VM (with GCC 10.2.1). So it does seem to a difference in how the 
two macOS installers were built. There were some changes in the build env and 
process between a7 and b1. I will investigate further and report back here. 
But, the good news is that, AFAICT, there is no reason to suspect a general 
Python performance regression on this benchmark between a7 and b1.

[issue43976] Allow Python distributors to add custom site install schemes

[Steve Dower]

Steve Dower  added the comment:

> "pip install as root" will need to continue to work and thus distros
> need to get a way to make sure that it doesn't corrupt the system
> installed packages

Excuse my ignorance, but does "as root" imply that there's no user 
site-packages directory at all?

I'm not imagining a solution that doesn't require *users* to change their 
commands, so if they're currently running "sudo pip install" because they need 
to, but we change it so they shouldn't, then I'm okay with them having to 
remove the "sudo". (At least for this discussion - we can evaluate transition 
plans separately.)

And yeah, patching sysconfig.py seems easier. But then, adding a file to the 
distro is even easier, and if it's easiest for Linux distros to do that via 
configure than to add a copy step into their build (which is how I'll do it for 
Windows distros that need it), then I'll leave that to others to 
decide/implement.

More modern Docker setups run the application itself under a non-root
user, but still install the packages and other dependencies as root.

See eg. Zammad's Dockerfile:
https://github.com/zammad/zammad-docker/blob/master/Dockerfile

Not sure whether that answers your question, though.

It's rather uncommon to install venvs inside Docker containers: one of the
main reasons for using containers is the added isolation, but it doesn't
make a lot of sense to add another layer of isolation inside the container.

"pip install as root" will need to continue to work and thus distros
need to get a way to make sure that it doesn't corrupt the system
installed packages. And perhaps distros can also patch pip to not
output those silly warnings anymore when using the system pip package :-)

Regarding the proposed solution: I'm not sure whether a new configure
option is the right way to go about this. Distros could simply patch
sysconfig.py, since that's the golden source of this information from
Python 3.10 onward.

setuptools' distutils version (and other packages which ship distutils)
will have to use this information instead of the copy which is/was
backed into distutils/sysconfig.py on Python 3.10+

(My assumption is that "--user" would essentially become the default if you're

you obviously get "default" behaviour, for better or worse.)

The "pip install" into a root environment approach is the standard way
to setup Docker (and similar) containers, so I think trying to break
this on purpose will not do Python a good service.

The pip warning about this kind of setup which apparently got added
in one of the more recent versions of pip already is causing a lot
of unnecessary noise when building containers and doesn't make Python
look good in that environment.

[issue44026] IDLE doesn't offer "Did you mean?" for AttributeError and NameError

[Dennis Sweeney]

Dennis Sweeney  added the comment:

Another idea: do what test_exceptions() does:

try:
f()
except NameError as exc:
with support.captured_stderr() as err:
sys.__excepthook__(*sys.exc_info())

self.assertNotIn("a1", err.getvalue())

Then instead of the assert, do something like

last_line = err.getvalue().rsplit("\n", 2)[-2]
_, did_you_mean, suggestion = last_line.rpartition("Did you mean: ")
if did_you_mean:
   print(did_you_mean + suggestion)

This can probably be done without test.support.

[issue44038] In documentation Section 8.6, the definition of parameter_list need correcting

[Webb Scales]

New submission from Webb Scales :

In Section 8.6 ("Function definitions"; 
https://docs.python.org/3/reference/compound_stmts.html#function-definitions), 
the definition of "parameter_list" looks slightly wrong:

parameter_list ::= defparameter ("," defparameter)* "," "/" ["," 
[parameter_list_no_posonly]] | parameter_list_no_posonly

The "/" (and the comma preceding it) is not a required component.  (Sorry, I'm 
afraid I'm not smart enough right now to suggest a correction.  :-p )

[issue43976] Allow Python distributors to add custom site install schemes

[Steve Dower]

Steve Dower  added the comment:

> I'd rather not have a new option here ...

Perhaps what I'm suggesting here is that I don't see any reason for "sudo pip 
install ..." into a distro-installed Python to ever need to work, and would be 
quite happy for it to just fail miserably every time (which is already the case 
for the Windows Store distro of Python).

Admin installed all-user packages is the expert scenario here, and can be as 
twisted as possible. Pip installed per-user packages and system-tool installed 
packages are the defaults, and the more easily those can be overridden by a 
file in the distro, the better.

[issue43976] Allow Python distributors to add custom site install schemes

[Steve Dower]

Steve Dower  added the comment:

The best option for restricting the import while still having it be a Python 
import is to find the file (if it's present in the expected location under 
sys.whatever), and then use importlib to import it: 
https://docs.python.org/3/library/importlib.html#importing-a-source-file-directly

I'd rather not have a new option here, I would much prefer "-S" in this context 
to mean "run Python with only core libraries" and "-s" to mean "run Python with 
only core and distro libraries" (and neither to mean "run Python with core, 
distro and user libraries").

That may be a bigger change, but there's enough angst around this issue that we 
would be better off getting it right this time, even if it changes things, than 
continuing to preserve the system that people dislike so much.

[issue44027] Python 3.9 UWP does not create key in PythonCore

[Steve Dower]

Steve Dower  added the comment:

Correct. It does, however, write to the lookaside space, which Windows will map 
back if you access it.

So reading HKLM\Software\Python\PythonCore\3.9 will return all the values that 
would be there. It's only enumeration that doesn't work. I've reported that to 
the team responsible, and they think it's not necessary, so I have no qualms 
about saying that you should *also* look in 
"SOFTWARE\\Microsoft\\AppModel\\Lookaside\\user\\Software\\Python\\PythonCore". 
(And if another redistributor also does a UWP package of Python, they'll have 
their own registry section for it to go into.)

Not writing into shared registry locations is one of the *best* features of 
this form of packaging, so I'm not inclined to try too hard to break it. 
Overall the robustness and stability is worthwhile, so it'll just fall to tool 
developers to catch up a bit, or alternatively win over the team that could 
just fix it properly.

[issue44026] IDLE doesn't offer "Did you mean?" for AttributeError and NameError

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

Those are intesting options, I will think about this. I am still afraid of 
adding more APIs in this area as having arbitrary Python getting call in the 
middle of handling the exceptions it can be quite tricky: think that we are 
handling an exception already so other exceptions can mess up stuff in very 
subtle ways or we need to ignore exceptions and that can also be dangerous.

Another thing we could do is reproduce the feature in idle itself with a custom 
display hook, which would be easier as we can just use difflib. It would be 
slightly different than the built-in one but honestly I don't think that's a 
problem at all. I understand that other people may think differently so I am 
open minded as well. But I wanted to clarify what are my worries :)

[issue38946] IDLE on macOS 10.15 Catalina does not open double-clicked files if app already launched

[Irv Kalb]

Irv Kalb  added the comment:

This is a quick follow up to the original issue.

I am now running Mac OS X 11.2.3 with IDLE 3.9.1 (and pygame 2.0.1).

In this environment, the issue of opening files is completely fixed and works 
perfectly.

Thank you very much (and a big thank you from my students who rely on this set 
up every day).

[issue44037] Broad performance regression from 3.10a7 to 3.10b1

[Raymond Hettinger]

New submission from Raymond Hettinger :

Running Tools/scripts/var_access_benchmark.py on the production macOS builds on 
python.org shows a performance drop-off between alpha-7 and beta-1.

Apple Silicon
-
read local4.1ns ->  4.5ns
read non_local4.1ns ->  4.6ns
read global   4.2ns ->  4.9ns
read builtin  4.2ns ->  5.3ns
classvar from cls10.1ns -> 12.6ns
classvar from inst9.5  11.7
read instvar  9.2  11.3
instvar with slots5.8   8.2
namedtuple   11.1  14.2
  ...

Since the effects are seen in almost every category, I suspect a build problem, 
a change to the eval loop, or a failure to inline some of the shared functions 
that used to be macros.

[issue44026] IDLE doesn't offer "Did you mean?" for AttributeError and NameError

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I realized after posting that looking for close matching is a performance issue 
and does not need to be done unless the exception is going to be displayed.  
But it is a shame to keep such great work away from many users.

What would you think of either

1. add sys.tracebackhook, to be called by the traceback display functions if 
not None.  Then idlelib.run.print_exception would not have to duplicate the 
sometimes changing logic for chaining or otherwise joining multiple tracebacks 
into one mega-traceback.  Instead, from what Dennis said above, it could set 
the hook and call the built-in exceptionhook.

2. add a new optional parameter to exceptionhook and the traceback display 
function.  This would have the same advantage as above.

[issue44034] Incorrect type casting of float into int

[Tim Peters]

Tim Peters  added the comment:

Please study the docs first:

https://docs.python.org/3/tutorial/floatingpoint.html

That will give you the background to understand why `int()` has nothing to do 
with this.

>>> 1.
2.0

That is, `int()` was passed 2.0 to begin with, because the binary float closest 
to the decimal value 1. is in fact 2.0.

If you can't live with that, use the `decimal` module instead:

>>> import decimal
>>> int(decimal.Decimal("1."))
1

[issue44033] Adding multiple keys of the same name to a dict doesn't raise an exception

[Shreyan Avigyan]

Shreyan Avigyan  added the comment:

I've read that issue but it seems that it actually was based on "Should there 
be a warning or error?". I actually suggest something different. I suggest that 
"Either raise an exception or just use the first key-value pair if the key is 
repeated during initialization". (By "initialization" I mean to say creating a 
new dict object)

[issue43882] [security] urllib.parse should sanitize urls containing ASCII newline and tabs.

[Seth Michael Larson]

Seth Michael Larson  added the comment:

Leaving a thought here, I'm highlighting that we're now implementing two 
different standards, RFC 3986 with hints of WHATWG-URL. There are pitfalls to 
doing so as now a strict URL parser for RFC 3986 (like the one used by 
urllib3/requests) will give different results compared to Python and thus opens 
up the door for SSRF vulnerabilities [1].

[issue44036] asyncio SSL server can be DOSed, event loop gets blocked: busy loops and uses 100% CPU

[ghost43]

New submission from ghost43 :

This is about a potential DOS vector that can get an asyncio server serving SSL 
connections to enter a busy loop and hang. To recover the server (python 
process) needs to be restarted.

See downstream report at https://github.com/spesmilo/electrumx/issues/92

ElectrumX is server software that serves JSON-RPC requests either directly over 
plaintext TCP or over SSL/TLS (no HTTP involved). The server code is written 
using asyncio. The most popular client is also written using python+asyncio. 
However, there are other server implementations (e.g. in Rust), and other 
clients (e.g. in javascript, scala, java). The servers are part of a federated 
network and peer with each other.

In the last 1+ year, server operators have started reporting that the python 
process (of ElectrumX) sporadically hangs: it uses 100% CPU and stops serving 
clients or accepting new connections. The only way we could find to recover is 
restarting the server (the python process); waiting for even days did not help, 
python was stuck. The hang seemed to mostly happen on busy servers that serve 
several thousands of concurrent sessions, and even on those only happened e.g. 
once a month. So the hang was difficult to reproduce.

Nevertheless we observed that the hang only happens if it is the asyncio server 
that handles SSL, i.e. if the server operator put nginx in front of the python 
process and handles SSL termination in nginx, they would be unaffected. One 
server operator whose server at one point hanged multiple times a day confirmed 
this, and reported that nginx subsequently started logging lines like this:
```
2021/01/11 02:28:30 [crit] 21#21: *437620 SSL_shutdown() failed (SSL: 
error:14094123:SSL routines:ssl3_read_bytes:application data after close 
notify) while proxying connection, client: REDACTED, server: 0.0.0.0:50002, 
upstream: "127.0.0.1:50213", bytes from/to client:81/205, bytes from/to 
upstream:205/0
```

Over these last months, the hang has been reproduced on many different python 
versions by different people, e.g. 3.7.1, 3.7.5, 3.8.5, 3.9.1, 3.9.4.

A few days ago, many servers hanged almost simultaneously, and when restarted, 
they would soon hang again at most a few hours later. Presumably someone either 
flooded the network with buggy clients, or it might have been an attack. 
Anyway, this allowed me to look into this better. I set up gdb and waited. This 
was on ubuntu 20.04 with python 3.8.5 and openssl=1.1.1f-1ubuntu2.3.

It seems the event loop thread is stuck in a busy loop.
The deepest common stack frame looks to be at

y = int(1.999) # fifteen decimal points
print(y)
1   # output is 1

y = int(1.) # sixteen decimal points
print(y)

It shows 1 when we type fifteen decimal whereas when we add sixteen decimal 
points the output becomes 2.

[issue44033] Adding multiple keys of the same name to a dict doesn't raise an exception

[Shreyan Avigyan]

New submission from Shreyan Avigyan :

Adding multiple keys of the same name to a dict should raise an exception but 
instead causes a different behavior. For example consider this code,

>>> d = {"x" : "First value", "x" : "Second value", "y" : "Third value"}

One would expect a error because there two keys with the same name or that 
Python will add "x" : "First value" and will skip "x" : "Second value". But the 
result is opposite,

>>> d
{'x': 'Second value', 'y': 'Third value'}

Is this a bug or is this an intended behavior? (I may have missed out 
information related to this in the documentation. Kindly correct me if that's 
the case.)

What I am missing? 3.10.0b1 includes the fixes for this issue, no? Is it 
because the fixes still require some changes in the source? If that's the case, 
we should mention it in the What's New

> I'm asking if pytest can make a release to update.

In any case, shouldn't that be requested in the pytest issue tracker?

[issue43978] Incorrect "versionadded" info in typing.NoReturn documentation

[Ken Jin]

Ken Jin  added the comment:

To answer the person who posted this on docs mailing list, after much 
investigation, it seems that this made it into 3.7.0, 3.5.4 and 3.6.2 .

Here's the 3.7.0 (alpha) commit for the initial implementation of 
typing.NoReturn:
https://github.com/python/cpython/commit/f06e0218ef6007667f5d61184b85a81a0466d3ae

https://github.com/python/cpython/commit/e612c28513b406779d187e5f816445c7d40d292b

https://github.com/python/cpython/commit/4b15e45895ca56ac5f7837cacb8cd3ccc26d1f66

[issue43624] Add underscore as a decimal separator for string formatting

[Terry Davis]

Terry Davis  added the comment:

If no one else has any comments, I'll assume there is consensus and start 
working on this. I have not contributed to CPython before, nor have I worked on 
production C code, so it may be a while before I get anywhere.

[issue44001] typing.Literal: args must be hashable, not immutable

[Ken Jin]

Ken Jin  added the comment:

Jelle, thanks for fixing up the docs. You're right here - anything that can be 
an element in a frozenset or used as a key in a dict works. And the current 
docs for sets says that means anything hashable: 
https://docs.python.org/3/library/stdtypes.html#set-types-set-frozenset

If you feel anything's amiss. Please don't hesitate to re-open this issue.

[issue43978] Incorrect "versionadded" info in typing.NoReturn documentation

[Ken Jin]

Ken Jin  added the comment:

Hi Miguel, with reference to 
https://github.com/python/cpython/pull/25760#issuecomment-830338306, Guido 
rejected the PR because he said that the current docs are correct.

This is a major point of confusion for many people, but here's why a single 
feature can be added in 2 versions: PEP 484 (Type Hints) was initially accepted 
as 'Provisional' (you can see what this means in PEP 1). To spare you the 
details, it's a special pass for typing.py to add new features in point 
releases, and to backport new features to older versions - even if they aren't 
bugfixes! This goes against what most of CPython allows (new features usually 
aren't allowed to be backported). However, at the time, typing.py was pretty 
new, so there wasn't much existing code to break anyways.

Another example is asyncio. Which has since lost its provisional status a long 
time ago AFAIK. typing.py became de-facto non-provisional in 3.7, though PEP 
484 hasn't been updated yet. This is why you may see stuff overlapping between 
3.5 and 3.6.

I hope you learnt something cool :). Hope to see you around contributing to 
other parts of CPython!

[issue44032] Store locals and evaluation stack should be stored in a contiguous, per-thread stack

[Mark Shannon]

New submission from Mark Shannon :

Currently, the local variables (inc. cell and free vars) for functions and the 
evaluation stack are kept in per-activation chunks in the frame object. This is 
not a good design for modern hardware.
The local variables and stack are amongst the hottest memory in the VM and 
should be stored in a contiguous stack in memory.

Allocating a per-thread stack would improve memory locality considerably, and 
pave the way to allocating heap objects for function activations lazily, only 
when needed for debugging and introspection.

Generators would still need heap allocated locals and stack, but that would be 
no worse than currently.

library not initialized pygame

[Quentin Bock]

code:
#imports and variable for loop
import pygame
running = True

#initializes pygame
pygame.init()
pygame.mixer.init()
pygame.font.init()

#creates the pygame window
screen = pygame.display.set_mode((1200, 800))

#Title and Icon of window
pygame.display.set_caption("3.02 Project")
icon = pygame.image.load('3.02 icon.png')
pygame.display.set_icon(icon)

#setting up font
pygame.font.init()
font = pygame.font.Font('C:\Windows\Fonts\OCRAEXT.ttf', 16)
font_x = 10
font_y = 40
items_picked_up = 0
items_left = 3

def main():
global running, event

#Game Loop
while running:
#sets screen color to black
screen.fill((0, 0, 0))

#checks if the user exits the window
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
pygame.quit()

def music():
pygame.mixer.init()
pygame.font.init()
pygame.mixer.music.load('onoken - load.mp3')  #places song into
queue
pygame.mixer.music.play(10, 0, 3)  #fist number indicates the
loop amount, second is the offset of the song, third is fading the song in
song_text = font.render("Song: onoken - load", True, (255, 255,
255))
screen.blit(song_text, (10, 750))
music()

def display_instruction(x, y):
pygame.font.init()
pygame.mixer.init()
instructions = font.render("Each level contains 3 items you
must pick up in each room.", True, (255, 255, 255))
instructions_2 = font.render("When you have picked up 3 items,
you will advance to the next room, there are 3.", True, (255, 255, 255))
instructions_3 = font.render("You will be able to change the
direction you are looking in the room, this allows you to find different
objects.", True, (255, 255, 255))

screen.blit(instructions, (10, 40))
screen.blit(instructions_2, (10, 60))
screen.blit(instructions_3, (10, 80))

display_instruction(font_x, font_y)
pygame.display.update()

main()

if you try to run this, I'm aware that the icon and music file will not
load because you don't have the file on your device, but if it somehow
works for you please let me know, and if you think there's any difference
between my code and when you ran it I need this figured out. Thanks

[issue42067] Type annotation in for-loops

[Ken Jin]

Ken Jin  added the comment:

@pablo, may I close this issue as 'not a bug'? I think it looks like a feature 
request that belongs on https://discuss.python.org/c/ideas/ or 
https://mail.python.org/mailman3/lists/python-ideas.python.org/ instead. What 
do you think?
