[issue37228] UDP sockets created by create_datagram_endpoint() allow by default multiple processes to bind the same port

[Jukka Väisänen]

Jukka Väisänen  added the comment:

I had a quick search through github for calls to create_datagram_endpoint() and 
the reuse_address is either not set or set explicitly to True, probably due to 
the error in the documentation.

Only in one case (of my admittedly small sample) did it seem like the parameter 
was set to True intentionally to get the behavior of binding multiple processes 
to the same port.

Due to the nature of the function, it is also often buried inside packages 
implementing higher level protocols (SIP, STUN, DNS, RTP) which want to create 
a convenience function to create asyncio servers and clients.

The deprecation warning and getting it into 3.6 and later sounds very 
reasonable to me.

[issue38845] test_shared_memory_SharedMemoryServer_ignores_sigint and others fail on Guix

[tlecarrour]

New submission from tlecarrour :

Dear Python Bugs Team,

Some tests fail when building Python 3.8 on Guix, for instance :

```
FAIL: test_shared_memory_SharedMemoryServer_ignores_sigint 
(test.test_multiprocessing_spawn.WithProcessesTestSharedMemory)
--
Traceback (most recent call last):
  File 
"/tmp/guix-build-python-3.8.0.drv-0/Python-3.8.0/Lib/test/_test_multiprocessing.py",
 line 3824, in test_shared_memory_SharedMemoryServer_ignores_sigint
os.kill(os.getpid(), signal.SIGINT)
AssertionError: KeyboardInterrupt not raised
```

This is because, on Guix, there is no TTY available during the build process.
A patch (cf attachment) has been added to the package definition [1], but it 
would make sense to have it integrated in Python.

[1]: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=38208#14

It adds the following decorator to the failing tests:

```
@unittest.skipUnless(sys.stdin.isatty(), "KeyboardInterrupts require a TTY 
device")
```

Regards

[Damien LEFEVRE]

Damien LEFEVRE  added the comment:

Back to testing this.

I have the same issue on Linux, i.e: the deadlock on PyGILState_Ensure.

I cannot test 3.8 because many of the modules are not yet available for this 
version.

I'll try making a small test application to reproduce the issue.

[issue38846] async: Return context manager from open(_unix)_connection

[Sebastian Rittau]

New submission from Sebastian Rittau :

As a convenience it would be useful if async.open_connection() and 
open_unix_connection() would return a context manager that closes the writer on 
exit:

with await open_unix_connection(...) as (reader, writer):
...

This could be achieved by using a custom sub-class of tuple:

class _ConnectionContext(tuple):
def __enter__(self):
return self
def __exit__(self, *args):
self[1].close()

I can submit a PR if wanted.

[issue38500] Provide a way to get/set PyInterpreterState.frame_eval without needing to access interpreter internals

[Fabio Zadrozny]

Fabio Zadrozny  added the comment:

@Mark @Brett

Well, PEP 523 still works (it's just more inconvenient to use now).

Still, if PEP 523 will still be supported I think that having the setter/getter 
makes sense.

If it is to be deprecated as @Mark is suggesting it doesn't really make sense 
to add it (but then, it should really be deprecated and ideally there'd be some 
replacement for the current debugger use... not sure about other use cases such 
as a jit, which was the initial target of PEP 523 -- @Mark, do you want to go 
that route/create a PEP to deprecate it so that this discussion takes place in 
a proper place?).

p.s.: as a note, bytecode modification on the actual object is not a usable 
approach for the debugger because users could break that in real-world use 
cases (i.e.: what happens if the user creates a **new** code and sets it to the 
code which had the breakpoint? What about breakpoint changes? Right now the 
debugger evaluates all assumptions just before the frame is executed, so, it's 
easier to get things right -- the case you posted currently does what's 
expected on pydevd). Still, a callback before the execution so that it could 
change the frame code before it's executed without the remainder of PEP 523 
would be enough (and maybe it could be adopted in other Python implementations 
too) -- actually, for the debugger it'd be awesome if the frame code could be 
changed from inside a trace call and then that stack would restart execution 
(close to what happens with setting the frame line to be executed), but I guess 
this would be a completely different request ;)

p.s.: please don't reply to my previous p.s. here (let's move the discussion to 
another place -- either by @Mark creating a PEP for discussion or acknowledging 
the issue is ok given the current status quo).

[issue38847] AST Optimization for Single Target List Comprehension

[Batuhan]

New submission from Batuhan :

I was going through old issues and I found @inada.naoki's comment on issue 36551

> How about converting `[x for x in it]` to `[*it]` in AST?

Is this feature still wanted? I can try to work on an implementation for this 
if there is a need. Also should this cover set (`{x for x in it}`) 
comprehensions?

[issue27724] PEP3119 inconsintent with actual CPython impl

[Guido van Rossum]

Guido van Rossum  added the comment:

Presumably when the implementation was done the IS_ABSTRACT name sounded more 
logical than just ABSTRACT. Since the PEP doesn't *specify* the name of this 
flag[1] I see no reason to change anything. Closing.

_
[1] The PEP mentions this flag exactly once:

(If this were implemented in CPython, an internal flag
``Py_TPFLAGS_ABSTRACT`` could be used to speed up this check [6]_.)

[issue38841] [asyncio] bind() on a unix socket raises PermissionError on Android for a non-root user

[Andrew Svetlov]

Andrew Svetlov  added the comment:

Do I understand you correctly: is Android forbids UDP Unix sockets for non-root 
user?
Maybe the socket path should point on another location to get the test passed?

[issue38841] [asyncio] bind() on a unix socket raises PermissionError on Android for a non-root user

[Xavier de Gaye]

Xavier de Gaye  added the comment:

No, it is the SELinux configuration on android devices that forbids binds to 
named UNIX sockets. Changing from a named UNIX socket to an unnamed UNIX socket 
would fix the problem. I don't know if all platforms support unnamed UNIX 
sockets.

The fix in issue #28684 (referenced in the OP) provides a new decorator to skip 
the test for platforms such as android.

[issue38500] Provide a way to get/set PyInterpreterState.frame_eval without needing to access interpreter internals

[Brett Cannon]

Brett Cannon  added the comment:

I think the real question is whether this is part of the CPython public API or 
the CPython internal API.

@Fabio how burdensome would it be if we placed this in the internal API that 
you can get access to but we don't make backwards-compatibility guarantees 
about? For instance, Victor wants to start passing in thread state which will 
change the API for 3.9, but we wouldn't expect to change it in a bugfix release.

[issue26278] BaseTransport.close() does not trigger connection_lost()

[Sümer Cip]

Sümer Cip  added the comment:

Closing the issue seems like a good idea: as it seems nobody seems to have 
spotted similar issue and I have only been able to reproduce it in Python 3.4. 

Just for future ref.: The uncommon thing is that the server I was using is a 
TCP game server holding long-running connections as opposed to short-lived HTTP 
connections, maybe there is a very random issue at the core but as it is 
happening very randomly.

[Fabio Zadrozny]

Fabio Zadrozny  added the comment:

@Bret

I don't really see a problem in breaking the API in major releases (so, having 
access for it in the internal API but without a backwards-compatibility 
guarantee seems like a good fit for me).

[issue38852] test_recursion_limit in test_threading crashes with SIGSEGV on android

[Xavier de Gaye]

New submission from Xavier de Gaye :

Actually it is the script that is spawned by test_recursion_limit that crashes 
with SIGSEGV on android API 24. Lowering the recursion limit in the script from 
1000 to 100 with sys.setrecursionlimit() fixes the problem.

[issue38853] set.repr breaches docstring contract

[Cat Chenal]

New submission from Cat Chenal :

S = {19,8,-1,25,0,1,2,3,4,5,6,7}
print('Set S = {{19,8,-1,25,0,1,2,3,4,5,6,7}}')

The set is represented by a new string-ordered set:
print(f'Its repr is:\n{S}\n')
Output:
{0, 1, 2, 3, 4, 5, 6, 7, 8, 19, 25, -1}

This is a breach of the contract stated in the docstring: "Build an unordered 
collection of unique elements."

Output:

@foo(dict(), defaultdict(lambda: 1))

Expected output:

@foo(dict(), defaultdict(lambda: 1))
def f():
pass


These changes to the decorator parameters cause the problem to disappear:

- @foo({}, defaultdict(lambda: 1))
- @foo(dict(), defaultdict(list))

[issue38855] test_unpack.py does not catch the unpacking of a set

[Cat Chenal]

New submission from Cat Chenal :

S = {19,8,-1,25,0,1,2,3,4,5,6,7}

a, *b, c = S
print('a:', a)
print('b:', b)
print('c:', c)

Output:
a: 0
b: [1, 2, 3, 4, 5, 6, 7, 8, 19, 25]
c: -1

Either test_unpack.py needs a test for "non-indexable object" to prevent this 
unpacking of a non-sequence, or the unpacking of a set should be implemented 
(granted the ordered repr of a set is changed to unordered, see Issue38853).

Being able to "unpack" a set would be nice to have, imho, because one would use 
that operation to obtain a partition (over unordered elements).

[issue38856] wait_closed() can raise ConnectionResetError

[issue38853] set.repr breaches docstring contract

[Steven D'Aprano]

Steven D'Aprano  added the comment:

I'm sorry, I don't understand what part of the documentation you think is 
violated here. The docs say that sets are unordered, but of course when 
printing the elements have to be given in *some* order.

The given output seems unordered to me: -1 is smaller than 25, but it appears 
last in the output.

The specific order you see will depend on the specific values in the set, as 
well as the order that they were inserted, deleted, and/or re-inserted in some 
arbitrary way. For example:

>>> repr({4, 5, 2**31+1, 2, 2**31+2, 3, 2**31, 0})
'{0, 2147483648, 2, 3, 2147483650, 2147483649, 5, 4}'


I don't think there is a bug here. Can you explain what you think the bug is, 
in detail please?

[issue33125] Windows 10 ARM64 platform support

[Dan]

Dan  added the comment:

According to this -
https://wiki.tcl-lang.org/page/Building+with+Visual+Studio+2017
the issue will be fixed in the next version (8.6.10). TLDR explanation: Tcl/Tk 
has variables with names that are now reserved keywords in VS2017, meaning that 
it can't be build with recent compilers and since VS2017 is the first compiler 
that has official ARM64 support it means that it currently can't be built for 
that target.
Anyway when version 8.6.10 is eventually released then it should (hopefully) 
build fine with the current scripts.
Maybe we can add it later when that happens?

[issue38857] AsyncMock issue with awaitable return_value/side_effect/wraps

[Jason Fried]

New submission from Jason Fried :

If you are trying to use AsyncMock to mock a coroutine that returns awaitable 
objects, AsyncMock awaits on those objects instead of returning them as is. 

Example:
  mock = AsyncMock(return_value=asyncio.Future())
  v = await mock()  # blocks on trying to await the future

Expected:
  mock = AsyncMock(return_value=asyncio.Future())
  v = await mock()
  assert isisnstance(v, asyncio.Future)

This problem affects side_effects and wraps.

[issue38858] new_interpreter() should reuse more Py_InitializeFromConfig() code

[STINNER Victor]

New submission from STINNER Victor :

Currently, new_interpreter() is a subset of Py_InitializeFromConfig(): the code 
was duplicated. I would prefer that both functions stay in sync and so that 
new_interpreter() reuses more Py_InitializeFromConfig() code.

[issue38859] AsyncMock says it raises StopIteration but that is Impossible

[Jason Fried]

New submission from Jason Fried :

If an AsyncMock uses a side_effect that is an Iterable, if called more than 
items exist its suppose to raise StopIteration according to the docs but PEP 
479 says that is impossible. 

My Suggestion is that we update the docs and the code to Raise a 
StopAsyncIteration since it will not be converted to a RuntimeError

[issue37228] UDP sockets created by create_datagram_endpoint() allow by default multiple processes to bind the same port

[David Cuthbert]

David Cuthbert  added the comment:

I'm working on patches for the deprecation bits (targeting 3.6 for now; will 
work my way up from there) for review, including documentation. Unless someone 
tells me to stop. :-)

In an attempt to make this not-so-Linux-specific, I'm reviewing how this works 
on non-Linux platforms (MacOS, FreeBSD) as well.

Reading Linux's socket(7) man page makes it seem like reuse_port is the issue 
(but that actually has protections to ensure you're only doing it across the 
same UID at least). I had to write my own test jig to (re-)convince myself 
that, indeed, reuse_addr is the problem.

[issue37228] UDP sockets created by create_datagram_endpoint() allow by default multiple processes to bind the same port

[David Cuthbert]

David Cuthbert  added the comment:

FreeBSD 12.1 and MacOS 10.15.1 (Catalina) appear to have saner and safer 
behavior.

Both require the use of SO_REUSEPORT for this behavior to happen as well. 
FreeBSD also requires the UID to be the same or 0 for subsequent processes to 
make the bind() call. I'll call this out as being Linux-specific in the 
deprecation message for now. (I don't have an AIX, HP-UX, or Solaris system 
handy to test, nor do I really want one if I'm being honest. :-) .)
