[issue33184] Update OpenSSL to 1.1.0h / 1.0.2o

[Ned Deily]

Ned Deily  added the comment:

Lisa, thanks for the offer but there's nothing much to be done.  It's just a 
reminder to Steve Dower for the Windows installer and to me for the macOS 
installer to update the respective installer build automation prior to the next 
releases.

[issue33012] Invalid function cast warnings with gcc 8 for METH_NOARGS

[Martin Panter]

Martin Panter  added the comment:

Sorry, I realize there is a problem remaining with the pointer types for 
"Noddy_name" (Noddy vs PyObject pointers), so you can't remove the cast there. 
But my suggestion should still apply to other places, for instance the 
"error_out" method in Doc/howto/cporting.rst.

[issue33219] x in IntFlag() should test int x's inclusion in IntFlag

[Ethan Furman]

Ethan Furman  added the comment:

Nitish, Flag can check if the current Flag class has a mixin, and if so if the 
object being checked for is of that same type.

Dutcho, my apologies.  Looks like I did not fully understand how __contains__ 
is supposed to work and a TypeError is completely appropriate.

Looking into deprecation cycles now to get the change scheduled.

[issue33217] x in enum.Flag member is True when x is not a Flag

[Ethan Furman]

Ethan Furman  added the comment:

Stepping back slightly, it is more general to say that str, and in certain 
other cases dict and set (and possibly others) will raise instead of return 
False when it is impossible for the target type to ever hold the checked-for 
type.  A couple examples of what will raise:

1 in 'hello'   # integers will never be in a string
list() in dict()   # dict keys must be hashable (and lists are not)

So, yes, at least for pure Enums and Flags, raising TypeError when a 
non-Enum/Flag is checked for would be appropriate.

Since there may be code currently relying on always getting True/False, though, 
a deprecation period is called for.  I'll see if I can get that into 3.7.

Why don't we make CancelledErrors having proper traceback a default behaviour?

[issue31033] Add argument to .cancel() of Task and Future

[Alexander Mohr]

Alexander Mohr  added the comment:

I was about to open a new bug, but I think my idea overlaps with this one.  
From what I understand there are two ways to cancel tasks:

1) calling task.cancel()
2) explicitly raising a CancelledError

with #2 you can get a traceback by catching the exception which yields why the 
task was cancelled (per callstack, and you create the CancelledError with a 
custom message).

#1 I think is what this is talking about.

The most useful information IMHO is the callstack, and via #1 this callstack is 
completely lost.

I like the idea of having an argument to construct the CancelledError with, but 
I like even more the ability to tell the exception that will be raised to have 
the traceback of the point where the task was originally cancelled.

Right now I have to use forbidden fruit to override the Task.cancel method and 
store the callstack in a custom attribute.

I was talking with asvetlov and and he thought perhaps there could be an 
environment variable to enable this by default and then when the cancellation 
error is raised it can have the caller's callstack...I think ideally this would 
be the default if it could be done cheaply (given if a regular exception throw 
contains the callstack, then a cancellation exception should always as well.

Ideally I think when a task is cancelled it instantiates the exception with the 
callstack at that point, and then does something like a "with e" to raise the 
exception from the future so you get it when it's raised.

[issue32873] Pickling of typing types

[Will T]

Will T  added the comment:

I believe I hit a bug with this fix (just pulled the code a few min ago):

In [10]: pickle.loads(pickle.dumps(typing.List))
Out[10]: typing.List

In [11]: pickle.loads(pickle.dumps(typing.FrozenSet))
---
PicklingError Traceback (most recent call last)
 in ()
> 1 pickle.loads(pickle.dumps(typing.FrozenSet))

PicklingError: Can't pickle typing.Frozenset: attribute lookup Frozenset on 
typing failed

The cause is in _GenericAlias.__init__

name = orig_name[0].title() + orig_name[1:]

Maybe just pass the name explicitly?

For context I originally hit this trying to explicitly getattr(typing, 
alias_name) not by pickling but I'm pleased to see that's at least apparently 
intended to be valid use (I need to get the underlying special's parameter 
variance which is lost when you give it args).

[issue33219] x in IntFlag() should test int x's inclusion in IntFlag

[Dutcho]

Dutcho  added the comment:

@Nitish
The easiest way would probably be to change __contains__ in Flag to:

def __contains__(self, other):
try:
return other & self == other # leave selection of _value_ attribute 
(if other is Flag) or conversion (if other is int mixin of IntFlag) to __and__
except TypeError:
return False

Although this would be somewhat convoluted (the generic delegation to __and__ 
isn't clear at first sight and therefore less maintainable) and may lead to 
confusing error messages

Since BEFORE_ASYNC_WITH always is followed by GET_AWAITABLE, in future they can

[issue33213] crypt function not hashing properly on Mac (uses a specific salt)

[Ronald Oussoren]

Ronald Oussoren  added the comment:

As far as I know macOS does not support different salt types at all. The 
manpage does mention an "extended crypt", but according to the documentation 
that just controls the number of DES rounds used.

In particular:

The salt is a 9-character array consisting of an underscore, followed by 
4 bytes of iteration count and 4 bytes of salt.  These are encoded as
printable characters, 6 bits per character, least significant character
first.  The values 0 to 63 are encoded as ``./0-9A-Za-z''.  This allows 
24 bits for both count and salt.


If anything needs to change it would have to be a macOS specific patch to the 
_crypt extension that rejects any attempt of using algorithm selection (but 
that's technically a backward incompatible change as)

[issue33223] test_posix fails ERRNO 0

[Ioannis Valasakis]

Ioannis Valasakis  added the comment:

Note: I get the same error with the version of python installed via homebrew:

[GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.39.2)] on darwin

Here is also the output of the id command, if that is helpful:

groups=20(staff),1(daemon),12(everyone),61(localaccounts),79(_appserverusr),80(admin),81(_appserveradm),98(_lpadmin),204(_developer),450(_xcs),701(1),33(_appstore),100(_lpoperator),250(_analyticsusers),395(com.apple.access_ftp),398(com.apple.access_screensharing),399(com.apple.access_ssh)

I am also attaching a dtrace log of the two liner that causes the bug.

[issue33224] "RuntimeError: generator raised StopIteration" in difflib.mdiff

[Jeff Kaufman]

New submission from Jeff Kaufman :

With python built at HEAD (c51d8c9b) and at 3.7b3 (fcd4e03e08) the code:

import difflib
for fromdata, todata, flag in difflib._mdiff(
["2"], ["3"], 1):
  pass

produces:

Traceback (most recent call last):
  File "/home/jefftk/cpython/Lib/difflib.py", line 1638, in _mdiff
from_line, to_line, found_diff = next(line_pair_iterator)
StopIteration

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/home/jefftk/icdiff/repro.py", line 3, in 
["2"], ["3"], 1):
RuntimeError: generator raised StopIteration

In python 3.5 and 3.6 I don't get an error.

This is probably due to https://bugs.python.org/issue32670 which implements PEP 
479, but I this this isn't supposed to happen in library code?

[issue31814] subprocess_fork_exec more stable with vfork

[Gregory P. Smith]

Gregory P. Smith  added the comment:

A raw os.posix_spawn() API has been added to 3.7.

vfork() would likely all sorts of other problems.  It is extremely complicated 
and implementations have bugs.  CERT says never to use it.
  https://wiki.sei.cmu.edu/confluence/pages/viewpage.action?pageId=87152373

When forking or threading is involved, you are already always at the mercy of 
all other code running in your process.  This is not new.

That some C/C++ libraries misuse pthread_atfork() is not a surprise.  But the 
bug is theirs.

We should not try to paper over others C and system call mistakes.  Their code 
needs fixing.
