[issue37267] os.dup() creates an inheritable fd when handling a character file on Windows

[STINNER Victor]

STINNER Victor  added the comment:

According to the discussion in PR 14051: if os.dup() fails to make the new file 
descriptor new inheritable for a character device, the error must not be 
ignored. Instead, the caller is supposed to use os.dup(fd, inheritable=False).

Before *this bugfix*, os.dup() didn't respect its contract: fd2 was inheritable 
sometimes. Now the caller is aware of such special case and so can handle it 
properly.

[issue37299] RuntimeWarning is NOT raised

[Paul Ganssle]

Paul Ganssle  added the comment:

I think the reason for the difference here is in the `no_error` function you 
never actually create the coroutine `true()`, so there's nothing to warn about.

One thing that's confusing things about this example is that the `false()` 
evaluates to True, because it returns a coroutine object (rather than the value 
`False`):

>>> async def false(): 
...: return False 
...:
 

>>> bool(false())   

True

If you expand your `false() or true()` statement, it's equivalent to:

x = false()
if not x:
x = true()

return await x

Since `false()` is truthy, you don't expect true() to ever be called, hence no 
warning.

@YoSTEALTH Does this make sense? Does it solve the issue?

[issue37189] PyRun_String not exported in python38.dll

[STINNER Victor]

STINNER Victor  added the comment:

Attached PR 14142 fix bpo-34646 regression.

> It shouldn't break existing code because PyRun_String has a macro expansion 
> to PyRun_StringFlags. ABI compatibility between major releases is not 
> provided.

Many applications don't use Python header files, but access directly libpython. 
For example, py2app uses dlsym():
https://bitbucket.org/ronaldoussoren/py2app/src/default/py2app/apptemplate/src/main.c

PyInstaller uses GetProcAddress() on Windows or dlsym() on other platforms:
* 
https://github.com/pyinstaller/pyinstaller/blob/1844d69f5aa1d64d3feca912ed1698664a3faf3e/bootloader/src/pyi_python.h
* 
https://github.com/pyinstaller/pyinstaller/blob/1844d69f5aa1d64d3feca912ed1698664a3faf3e/bootloader/src/pyi_pythonlib.c

That's why PyRun_String() is defined as an alias using a macro *and* as a 
function in pythonrun.c:

#undef PyRun_String
PyObject *
PyRun_String(const char *str, int s, PyObject *g, PyObject *l)
{
return PyRun_StringFlags(str, s, g, l, NULL);
}

[issue37312] Remove deprecated _dummy_thread and dummy_threading modules

[STINNER Victor]

STINNER Victor  added the comment:

Python 3.7 has been modified to always require threading support:

* https://bugs.python.org/issue31370
* https://mail.python.org/pipermail/python-dev/2017-September/149156.html

commit a6a4dc816d68df04a7d592e0b6af8c7ecc4d4344
Author: Antoine Pitrou 
Date:   Thu Sep 7 18:56:24 2017 +0200
 
bpo-31370: Remove support for threads-less builds (#3385)
   
* Remove Setup.config
* Always define WITH_THREAD for compatibility.

--

In Python 3.8, the dummy_threading module is documented as:

"This module provides a duplicate interface to the threading module. It was 
meant to be imported when the _thread module was not provided on a platform.

Be careful to not use this module where deadlock might occur from a thread 
being created that blocks waiting for another thread to be created. This often 
occurs with blocking I/O."

https://docs.python.org/dev/library/dummy_threading.html

And the doc starts with: "Deprecated since version 3.7: Python now always has 
threading enabled. Please use threading instead."

IMHO it's now time to remove this module.

--

I proposed to remove these modules today after I saw a bug on _dummy_thread: 
bpo-36688.

[issue37299] RuntimeWarning is NOT raised

[YoSTEALTH]

YoSTEALTH  added the comment:

Yes, this was the previous conclusion.

In a large code base, its hard to find such solution easily! There are many 
cases where `await` is not called and `RuntimeWarning` is not raised. Hard to 
narrow down the exact problem.

Maybe there needs to be a better way to evaluate coroutine vs waiting for the 
garbage collection to happen to riase `RuntimeWarning`

Paul, thanks for taking time to answer :)

[issue34631] Upgrade to OpenSSL 1.1.1c, 1.1.0k, and/or 1.0.2s

[Ned Deily]

Ned Deily  added the comment:

It looks we missed the window for 3.7.4 here.  (I assume the Windows installer 
build is not using 1.1.1.  Steve?)  Talking with Christian about this in IRC, 
we agreed, the CI pipelines (Azure and travis) are now using 1.1.1c and I've 
put a request to the buildbot owners to upgrade to 1.1.1c if possible.  So 
let's retarget 1.1.1c for 3.7.5 then which will be right around the time 1.1.0 
support ends.  In the meantime, we should update other installers to 1.1.0k and 
1.0.2s.

[issue37315] Deprecate using math.factorial() with floats

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

Currently math.factorial() accepts integer-like objects (including objects with 
defined __index__) as well as float instances with integral value (but not 
arbitrary float-like objects with defined __float__). I suppose this was happen 
because factorial() was the first integer functions in the math module, and all 
other functions accepted floats at that time. See also issue7550. But now we 
have more pure integer functions in the math module: gcd, isqrt, comb, perm. 
Seems accepting floats in factorial was a mistake. Now we can fix it, and 
deprecate using factorial() with floats.

Initial version of factorial() accepted also non-integral numbers (except 
float) with defined __int__. It was fixed in issue33083.

[issue37299] RuntimeWarning is NOT raised

[Andrew Svetlov]

Andrew Svetlov  added the comment:

The solution is called static analyzers and "type hints".
Mypy detects the absence of "await" pretty well.
In turn, CPython does the best in runtime mode for detecting not-awaited 
awaitables when possible.

I think we should close the issue, it doesn't show a bug but requests for 
nice-to-have thing which is solved by another tool.

[issue35998] test_asyncio: test_start_tls_server_1() TimeoutError on Fedora 29

[Andrew Svetlov]

Andrew Svetlov  added the comment:

No idea what to do.
SSL support is obviously broken.
Current code is too complex to maintain.

Yuri has a full reimplementation of ssl_proto.py in uvloop.
It *seem* to work and can be backported.

I'm sick now, can be ready to work back in a day or two.

[issue35031] test_asyncio test_start_tls_server_1 fails in AMD64 FreeBSD CURRENT buildbots

[STINNER Victor]

STINNER Victor  added the comment:

Commit f6a47f3e316cede2a07a1f74a509f6d80ab8fef0 introduced a workaround on 
Windows and FreeBSD. It was removed by commit 
f0749da9a535375f05a2015e8960e8ae54877349 in bpo-35998... but then Windows 
restarted to fail:
https://bugs.python.org/issue35998#msg345644

So I wrote PR 14148 to reintroduce the workaround until someone finds time to 
have a look.

Note: this issue is open since October 2018.

[issue37316] mmap.mmap() passes the wrong variable to PySys_Audit()

[Zackery Spytz]

New submission from Zackery Spytz :

new_mmap_object() should pass the fd variable to PySys_Audit(), not fileno.

Also, there's a missing call to va_end() in PySys_Audit() itself.

[issue37301] CGIHTTPServer doesn't handle long POST requests

[vsbogd]

vsbogd  added the comment:

Yeah, I have seen this comment as well. As I see this code for the first time I 
am not very familiar with it. 

It seems that this explanation is related to the case when non-Python CGI 
script is executed:

os.dup2(self.rfile.fileno(), 0)
os.dup2(self.wfile.fileno(), 1)
os.execve(scriptfile, args, env)

https://github.com/python/cpython/blob/3a1d50e7e573efb577714146bed5c03b9c95f466/Lib/http/server.py#L1176-L1178

On one hand the comment seems reasonable: as fileno is duped one cannot just 
read from it ahead of time. On the other hand few lines earlier one can see:

# throw away additional data [see bug #427345]
while select.select([self.rfile], [], [], 0)[0]:
if not self.rfile.read(1):
break

https://github.com/python/cpython/blob/3a1d50e7e573efb577714146bed5c03b9c95f466/Lib/http/server.py#L1163-L1166

which also seems like reading ahead of time.

My opinion this case should be tested after fix and if it works then fix can be 
applied without hesitation.

[issue34631] Upgrade to OpenSSL 1.1.1c, 1.1.0k, and/or 1.0.2s

[Ned Deily]

Ned Deily  added the comment:

> (I assume the Windows installer build is not using 1.1.1.  Steve?)

After doing a little more homework and better understanding 
PCbuild/get_externals.bat, https://github.com/python/cpython-source-deps, and 
https://github.com/python/cpython-bin-deps and their twisting branches, it 
appears we *are* using 1.1.1, in particular, 1.1.1b for 3.7 and 3.8 Windows 
builds.  So:

1. Can/should be try to update to 1.1.1c for 3.7.4 on Windows, and

2. Should I try to update the macOS installer to 1.1.1c for 3.7.4?

For the latter, I'll give it a try and see how smoothly it goes before making a 
final decision.

Ned Deily  added the comment:

As far as I can tell, the only thing left to do for this issue is to add a

[Jeremy Kloth]

Jeremy Kloth  added the comment:

The test run was stopped by me terminating the stuck processes on the buildbot 
worker itself.  This happens approximately once a month or so.

As of late, its been stuck in test_concurrent_futures, but it can get stuck in 
any test that uses multiprocessing (the spawned pool never terminates).

[issue4198] os.path.normcase gets fooled on windows with mapped linux network drive

[Mark Summerfield]

Mark Summerfield  added the comment:

When running a VirtualBox Windows 7 guest on Linux I have found that 
os.path.samefile() returns False when the filenames are the same, e.g.,

f = r'V:\pdfs\boson1.pdf'
same = os.path.samefile(f, f)
print(same) # expected True; got False

I mention it here because it may be part of the same problem.
I'm using Python 3.7.2.

Rebooting ought to by and large determination that. In the event that it 
doesn't, you're either taking a gander at genuine OS defilement (worth testing 
if some other MSI installers work - Anaconda does not utilize MSI) or plate 
debasement.

[issue37317] asyncio gather doesn't handle custom exceptions that inherit from BaseException

[Carlos Mermingas]

New submission from Carlos Mermingas :

asyncio.gather doesn't handle custom exception exceptions that inherit from 
BaseException in the same manner that it handles those that inherit from 
Exception, regardless of whether return_exceptions is set to True or False.

In the example below, I am using return_exceptions=True. If the custom 
exception inherits from Exception, a list printed, as expected. Conversely, if 
the custom exception inherits from BaseException, it is propagated:


import asyncio


class CustomException(BaseException):  # It works if base class changed to 
Exception
pass


async def do_this(x):
if x == 5:
raise CustomException()
await asyncio.sleep(1)
print(f'THIS DONE: {x}')


async def main():
print('BEGIN')
tasks = [do_this(x) for x in range(1, 11)]
result = await asyncio.gather(*tasks, return_exceptions=True)
print(f'Result: {result}')
print('END')


asyncio.run(main())

[issue37318] builtins.True exists but can't be accessed

[ChrisRands]

New submission from ChrisRands :

On Python 3:

>>> import builtins
>>> 'True' in dir(builtins)
True
>>> builtins.True
  File "", line 1
builtins.True
^
SyntaxError: invalid syntax
>>> 

So "True" is a keyword, I guess this explains the behaviour, but still seems 
odd to me?

Relevant SO question:

[issue35360] Update SQLite to 3.26 in Windows and macOS installer builds

[Steve Dower]

Steve Dower  added the comment:

Has anyone tried building with the newer SQLite and confirmed that the tests 
and any scenarios they use still work?

We don't currently have a SQLite expert to do these kinds of things.

There is an issue with the Python workaround 
`multiprocessing.reduction.register(types.MethodType, my_reduce)` that you 
proposed. If you then instantiate a `multiprocessing.Manager()` you get this

[issue34631] Upgrade to OpenSSL 1.1.1c, 1.1.0k, and/or 1.0.2s

[Steve Dower]

Steve Dower  added the comment:

The canonical source of versions used on Windows is in PCbuild/python.props

I'll pull the 1.1.1c sources into cpython-source-deps and run a build. If all 
goes smoothly, we can consider it, but I don't have a huge amount of time for 
CPython this week I'm afraid.
