Clearing co_quickened is easy, but it would requires changes to the build 
system to change the build order on Windows and bootstrap interpreter on 
Windows. I manually edited the Windows project files but it requires generating 
deepfreeze.c before hand. It cleared around ~60 memory blocks on Windows.

[issue46485] ~ PEG operator in the grammar

2022-01-23 Thread Robert Einhorn



New submission from Robert Einhorn :

This is probably not an error and I may misinterpret the PEP 617, but I don't 
know what the ~ PEG operator means in the next rule if there is no alternative:
assignment_expression:
| NAME ':=' ~ expression


And similarly with this rule if there is no more alternative:
assignment:
| NAME ':' expression ['=' annotated_rhs ] 
| ('(' single_target ')' 
 | single_subscript_attribute_target) ':' expression ['=' annotated_rhs 
] 
| (star_targets '=' )+ (yield_expr | star_expressions) !'=' [TYPE_COMMENT] 
| single_target augassign ~ (yield_expr | star_expressions)

It means the same as if there is alternatives: if it fails to parse then it 
will immediately fail. We place them in rules like this in preparation for 
extension or in case there are invalid_* rules in the same set (which doesn't 
appear in the grammar definition).

[issue46465] Regression caused by CALL_FUNCTION specialization for C function calls

2022-01-23 Thread Ken Jin



Ken Jin  added the comment:

A short summary (thanks to Victor's findings!):

- os.kill(pid, signal.SIGINT) is specialized to CALL_NO_KW_FAST
- CALL_NO_KW_FAST doesn't check eval breaker, so the signal is ignored
- signal handler wasn't called, test fails

I'd like to add tests for some of the other CALL_X in the future, but I'm a 
little short on time at the moment, sorry! For now, I've tried to turn some of 
the tests "hot" to see if I can get those to trigger.

[issue46465] Regression caused by CALL_FUNCTION specialization for C function calls

2022-01-23 Thread Mark Shannon



Mark Shannon  added the comment:

Is this a bug?

Signal handling in Python is asynchronous. 
https://docs.python.org/3/library/signal.html#execution-of-python-signal-handlers

The example code tests whether the interpreter responds synchronously and 
immediately.

If you add `for _in range(1): pass` or a call to any Python function in between 
the `os.kill(pid, SIGNUM)` and the `if not self.called:` then the test passes.

STINNER Victor  added the comment:

> Is this a bug?

In Python 3.10, the code works. In Python 3.11, it fails.

It's a behavior change. IMO this change is unwanted. I expect that signals are 
handled "as soon as possible", *especially* if we receive it "during" an 
os.kill() call on the current process on purpose.

[issue46465] Regression caused by CALL_FUNCTION specialization for C function calls



STINNER Victor  added the comment:

It's also interesting to note that the implementation of os.kill() and 
signal.raise_signal() do *not* call PyErr_CheckSignal().

The following signal functions *do* call call PyErr_CheckSignal():

* signal.signal()
* signal.pause()
* signal.pthread_kill()
* signal.pthread_sigmask()

Some other signal functions call PyErr_CheckSignal() if a syscall fails with 
EINTR (PEP 475).

See my previous comment: "CHECK_EVAL_BREAKER() matters for signals, but also 
multithreading (drop the GIL), asynchronous exception and pending calls."

If a thread executes a function which only uses opcodes which don't call 
CHECK_EVAL_BREAKER(), I understand that it can eat more than its slice of 5 ms, 
see sys.getswitchinterval():
https://docs.python.org/dev/library/sys.html#sys.getswitchinterval

So it's also a threads scheduling issue, no?

[issue46476] Not all memory allocated by _Py_Quicken() is released at Python exit



STINNER Victor  added the comment:

> See branch https://github.com/kumaraditya303/cpython/commits/fix-code

Oh nice, I like this new _Py_Deepfreeze_Fini() function :-) I suggest to create 
a function specific to only clear immortal code objects. In my experience, it's 
important to control exactly when objects are cleared at Python exit: 
Py_Finalize() is complex and fragile. See my notes:
https://pythondev.readthedocs.io/finalization.html

Be careful, Python must remain usable after Py_Finalize(): it's legit to call 
Py_Initialize() again and execute new Python code. Example executing the same 
code 4 times, each time Py_Initialize() and Py_Finalize() are called:

./Programs/_testembed test_repeated_init_exec 'print("Hello")'

My _PyStaticMethod_Dealloc() implementation uses Py_CLEAR() rather than 
Py_XDECREF() to set structure members to NULL.

Moreover, there are more things than just co_quickened which should be cleared. 
I suggest to add a new function to clear an "immortal" code object. For 
example, I also suggest to call PyObject_ClearWeakRefs(). I guess that co_extra 
should also be cleared.

[issue46483] `pathlib.PurePath.__class_getitem__` does not return `GenericAlias`



Serhiy Storchaka  added the comment:

Why __class_getitem__ was added in PurePath at first place? PurePath should not 
be a generic class, unlike to os.PathLike. For os.PathLike the type parameters 
represent the returning type of os.fspath() (either str or bytes), but the 
pathlib module only supports paths as strings, so no parametrization is needed.

I think PurePath.__class_getitem__ should be removed.

[issue46483] `pathlib.PurePath.__class_getitem__` does not return `GenericAlias`

2022-01-23 Thread Alex Waygood



Alex Waygood  added the comment:

It looks like __class_getitem__ was added to PurePath at @asvetlov's request  
in PR 17498. But, I'm also not quite sure why. The class is not generic in 
typeshed, so type-checkers will raise an error if you do PurePath[str], even if 
it is possible to do so at runtime.

Typeshed stub for PurePath:

With the current design, it isn't possible though because the code objects are 
modified in place so if co_quickened is freed the VM still tries to execute the 
copied instructions.

[issue46488] listsort.txt wrongly assumes you cannot calculate leading zeros in O(1) time.

2022-01-23 Thread Barry Schwartz



New submission from Barry Schwartz :

The Objects/listsort.txt incorrectly implies that it is not possible to compute 
leading zero bits in O(1) time, using only standard C. For a fixed integer size 
it can be done, for instance, using de Bruijn sequences. See 
https://www.chessprogramming.org/BitScan

(The existence of such methods is not as widely known as it ought to be.)

[issue41682] [Windows] test_asyncio: Proactor test_sendfile_close_peer_in_the_middle_of_receiving failure



Guido van Rossum  added the comment:

I'm wondering if the test is faulty. It seems to call EventLoop.sendfile() with 
a file that is 8K + 1 byte long,
and the protocol is instructed to close after 1K bytes have been written, but 
it seems to try to send as much of the file as it can.
Could it be that on Win22 the primitive used (TransmitFile) has an internal 
minimum buffer size that exceeds this file size, so the first call sends the 
whole file and there's no error?

@Andrew Svetlov, do you know enough of the internals of this code to validate 
my theory?

[issue46376] PyMapping_Check returns 1 for list



Serhiy Storchaka  added the comment:

It is difficult to distinguish Mapping from Sequence because they have the same 
set of dunder methods. The difference is only in semantic -- __iter__ yields 
items for Sequence and keys for Mapping, __getitem__ gets an item by index (or 
a sequence by slice) for Sequence and value by key for Mapping. But semantic 
cannot be tested here.

In these cases when both Sequence and Mapping are accepted but handled 
differently (like in the dict constructor) we test for existence of the "keys" 
method. It is not good, because it is not a dunder method, and therefore should 
be looked up at instance, not only at a type.

[issue46285] protocol_version in http.server.test can be ignored

2022-01-23 Thread Géry


Géry  added the comment:

Thanks Hugo for opening this issue and Éric for inviting me.

As you guys pointed out, function test in module http.server expects a real 
handler class argument (SimpleHTTPRequestHandler or CGIHTTPRequestHandler), not 
a partial object partial(SimpleHTTPRequestHandler, directory=args.directory) or 
partial(CGIHTTPRequestHandler, directory=args.directory), so that the 
assignment of protocol_version class attribute in test is not ignored.

The partial object in the if __name__ == '__main__' branch of module 
http.server was introduced in the first place to pass the directory argument to 
the handler class’s __init__ method called in method BaseServer.finish_request:

def finish_request(self, request, client_address):
"""Finish one request by instantiating RequestHandlerClass."""
self.RequestHandlerClass(request, client_address, self)

But finish_request is a factory method of BaseServer (the abstract creator) so 
it is DESIGNED to be overridden in subclasses to customize the instantiation of 
the handler class BaseRequestHandler (the abstract product). So the proper way 
to instantiate SimpleHTTPRequestHandler and CGIHTTPRequestHandler with the 
directory argument is to override BaseServer.finish_request.

That is what I have just did by updating my PR here: 
https://github.com/python/cpython/pull/30701/commits/fc7f95f9d270a8a83cb2fd6d51eb0f904b85e0d9

It fixes both #46285 and #46436.

[issue46436] Pass the -d/--directory command-line option to http.server.CGIHTTPRequestHandler

2022-01-23 Thread Géry


Géry  added the comment:

Thanks for mentioning this issue @merwok.

As you pointed out, function `test` in module 
[`http.server`](https://github.com/python/cpython/blob/main/Lib/http/server.py) 
expects a real request handler class argument (`SimpleHTTPRequestHandler` or 
`CGIHTTPRequestHandler`), not a partial object 
`partial(SimpleHTTPRequestHandler, directory=args.directory)` or 
`partial(CGIHTTPRequestHandler, directory=args.directory)`, so that the 
assignment of `protocol_version` class attribute in test is not ignored.

The partial object in the `if __name__ == '__main__'` branch of module 
`http.server` was introduced in the first place to pass the directory argument 
to the request handler class’s `__init__` method called in method 
`BaseServer.finish_request` of module 
[`socketserver`](https://github.com/python/cpython/blob/main/Lib/socketserver.py):

def finish_request(self, request, client_address):
"""Finish one request by instantiating RequestHandlerClass."""
self.RequestHandlerClass(request, client_address, self)

But `BaseServer.finish_request` is a factory method of `BaseServer` (the 
abstract creator) so it is *designed* to be overridden in subclasses to 
customize the instantiation of the request handler class `BaseRequestHandler` 
(the abstract product). So the proper way to instantiate 
`SimpleHTTPRequestHandler` and `CGIHTTPRequestHandler` with the `directory` 
argument is to override `BaseServer.finish_request`.

I have just updated my PR to implement this. It fixes both 
[#46285](https://bugs.python.org/issue46285) and 
[#46436](https://bugs.python.org/issue46436).

[issue46489] webbrowser crashes Ubuntu kernel

2022-01-23 Thread Danylo

New submission from Danylo :

I've been hunting this problem for half a year already. With other hypotheses
rejected - Linux issue, old PC, PyCharm bug, bad luck, - the webbrowser Python
lib supposedly makes the Ubuntu kernel panic.

Either from a terminal or within PyCharm (happens on both), I run

```
controller = webbrowser.get('google-chrome')
for link in links_list: # up to 10 items
controller.open(link)
time.sleep(1)
```

and the system crashes (hangs until a hard or soft reset) after several web
pages are opened in my Chrome browser as the result of running the program.

All the details you'll find at
https://askubuntu.com/questions/1370213/ubuntu-hangs-and-becomes-unresponsive-until-reset.
I first thought it's something wrong with Ubuntu, and I opened a question on
the forum.

The only detail I've not added there is that after each crash I can move the
mouse on the screen but cannot interact with anything. That thing always
puzzled me.

I can neither say the website I'm running the webbrowser nor test it on other
domains - the issue happens sporadically, once in several hours of me opening
and closing a Chrome browser controlled by the webbrowser lib.

Python 3.9.7, installed with Anaconda. I've tried older versions of Python.

Ubuntu 20.04 LTS.

[issue46490] Add "follow_symlinks=False" support for "os.utime()" on Windows

2022-01-23 Thread Delgan



New submission from Delgan :

Hi.

Currently, trying to use "os.utime(path, timestamps, follow_symlinks=False)" 
raises a exception on Windows: "NotImplementedError: utime: follow_symlinks 
unavailable on this platform".

Looking at the Win32 API it seems possible to open a symbolic link by 
specifying the "FILE_FLAG_OPEN_REPARSE_POINT" flag: 
https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-createfilew#symbolic-link-behavior

Do you think it would be possible to update "os.utime()" implementation and 
optionally pass the flag here: 
https://github.com/python/cpython/blob/ca78130d7eb5265759697639e42487ec6d0a4caf/Modules/posixmodule.c#L5516

[issue46491] typing: allow Annotated in outermost scope

2022-01-23 Thread Gregory Beauregard



New submission from Gregory Beauregard :

Currently, `typing.Annotated` (PEP 593) cannot be used at runtime with 
`typing.Final` and `typing.ClassVar` with `Annotated` on the outside:

```
from typing import Annotated, Final
# TypeError: typing.Final[int] is not valid as type argument
var: Annotated[Final[int], "foo"] = 4
```

The only tenuously related mention of this I can find in a PEP is in PEP 593 
(Annotated) which states "The first argument to Annotated must be a valid type".

I believe the runtime behavior should be changed to allow any ordering for 
`Annotated` with `ClassVar` and `Final`. This was discussed in the typing-sig 
PEP 655 thread (TypedDict `Required` and `NotRequired`) where the current plan 
is to allow `Required`/`NotRequired` in any nesting order with `Annotated` 
while suggesting the `ClassVar`/`Final` ordering restriction be lifted: 
https://mail.python.org/archives/list/typing-...@python.org/message/22CJ5TJGIJ563D6ZKB7R3VUZXTZQND5X/

The argument for doing so is on the mailing list: 
https://mail.python.org/archives/list/typing-...@python.org/message/MPMOIBX3XFXCD4ZNDC6AV4CLSI5LN544/

To summarize: adopting an overly strict view of what constitutes a valid type 
for `Annotated` creates difficulties for people who use runtime introspection 
of `Annotated` annotations by requiring them to parse additional typing or 
field annotations (https://bugs.python.org/msg411067). This needlessly 
exacerbates tension between typing and non-typing uses of annotation space. In 
order to be a good citizen to other annotation users, the `Annotated` runtime 
ordering restriction should be lifted.
