[issue42402] Termios module documentation is extremely lacking

[Dan Merillat]

New submission from Dan Merillat :

"The interpretation of the flags and the speeds as well as the indexing in the 
cc array must be done using the symbolic constants defined in the |termios| 
module."  (termios links to itself)

These constants are not listed in the documentation and the termios module is 
installed as a shared library so you can't read it without going to the source.

Furthermore the example in the documentation uses the following example:

new = termios.tcgetattr(fd)
new[3] = new[3] & ~termios.ECHO  # lflags

Which is explicitly against the documentation on the same page.
This has led to most searches on the net turning up people using magic numbers 
in places instead of symbolic values.

Inserting a list of constants with an extremely brief description would improve 
the module documentation dramatically.

[issue42392] remove the 'loop' parameter from __init__ in all classes in asyncio.locks

[Andrew Svetlov]

Andrew Svetlov  added the comment:

Perhaps Kyle is right, I had a misunderstanding with `get_running_loop()` vs 
`_get_running_loop()`.

The last version seems good except for the rare chance of race condition.

The safe code can look like:

global_lock = threading.Lock()  like GIL

   def _get_loop(self):
   loop = asyncio.get_running_loop()
   if self._loop is None:
# the lock is required because
# the thread switch can happen
# between `self._loop is None` check
# and `self._loop = loop` assignment
with global_lock:
if self._loop is not None:
self._loop = loop
   if loop is not self._loop: raise

The alternative is using the fast C atomic `compare_and_swap` function
which is executed under the hold GIL.
We need the pure-Python fallback anyway.

Multithreading is hard...

[issue42142] test_ttk timeout: FAIL tkinter ttk LabeledScale test_resize, and more

[Terry J. Reedy]

Terry J. Reedy  added the comment:

> Would this not also stop a number of IDLE tests? (Terry?)

Yes, at least half of them.  It took years to get us to run gui tests with the 
X simulator mock.  When we first added gui tests for IDLE in 2013, they (and 
the t/tk gui tests) were only run on Windows.

Please do not undo that.  Better to kill just wait-visibility on Linux.

[issue42392] remove the 'loop' parameter from __init__ in all classes in asyncio.locks

[Kyle Stanley]

Kyle Stanley  added the comment:

Regarding the example _get_loop():

```
   def _get_loop(self):
   loop = asyncio.get_running_loop()
   if self._loop is None:
self._loop = loop
   if loop is not self._loop: raise
   if not loop.is_running(): raise
```

Would this be added to all asyncio primitives to be called anytime a reference 
to the loop is needed within a coroutine?

Also, regarding the last line "if not loop.is_running(): raise" I'm not 100% 
certain that I understand the purpose. Wouldn't it already raise a RuntimeError 
from `asyncio.get_running_loop()` if the event loop wasn't running?

The only thing I can think of where it would have an effect is if somehow the 
event loop was running at the start of `_get_loop()` and then the event loop 
was stopped (e.g. a loop in an alternative thread was stopped by the main 
thread while the alternative thread was in the middle of executing 
`_get_loop()`). But to me, that seems to be enough of an edge case to simplify 
it to the following:


```
   def _get_loop(self):
   loop = asyncio.get_running_loop()
   if self._loop is None:
self._loop = loop
   if loop is not self._loop: raise
```

(Unless you intended for the first line `loop = asyncio.get_running_loop()` to 
instead be using the private `asyncio._get_running_loop()`, which returns None 
and doesn't raise. In that case, the original would be good to me.)

Other than that, I think the approach seems solid.

It never raises when called from inside a coroutine. And I propose to do that. 
So it will never fail.

[issue42392] remove the 'loop' parameter from __init__ in all classes in asyncio.locks

[Andrew Svetlov]

Andrew Svetlov  added the comment:

Despite the fact that asyncio.get_running_loop() never returns None but raises 
RuntimeError (and maybe other tiny cleanups), 
I can live with the proposal.

It doesn't make a system worse at least and backward compatible.
We can return to the idea of raising a warning from the constructor later, on 
collecting more feedback.

P.S.
There is a subtle non-deterministic behavior in the proposal: if the lock is 
accessed from a concurrent thread, the exception about wrong usage will be 
raised later at an arbitrary code point.
This is a well-known problem of the lazy initialization pattern and maybe we 
should do nothing with it. The programming is a compromise always.

[issue42142] test_ttk timeout: FAIL tkinter ttk LabeledScale test_resize, and more

[E. Paine]

E. Paine  added the comment:

> Could that bot be configured to run tests with -u-gui?

This has been found to not just affect one machine: it is both Azure and Github 
Ubuntu. Therefore, the only Ubuntu bot still running gui tests would be Travis.

It could be done (with a very small patch) but:
1. I not sure about disabling all tkinter gui tests when most appear to be fine 
still
2. Would this not also stop a number of IDLE tests? (Terry?)
3. Would you intend for this to be temporary or more permanent?

[issue42392] remove the 'loop' parameter from __init__ in all classes in asyncio.locks

[Yury Selivanov]

Yury Selivanov  added the comment:

Yeah, I follow the reasoning.

My use case:

   class Something:
  def __init__(self):
  self._lock = asyncio.Lock()

  async def do_something():
  async with self._lock:
  ...

And `Something` won't be created in a coroutine. So now I have to jump through 
the hoops to implement lazy lock instantiation.


> But the lock is tightly coupled with a loop instance. In other words, the 
> loop belongs to the loop.
>The lock cannot be used after the loop dies (stopped and closed).

I agree. Maybe the solution should be this then:


class asyncio.Lock:

   def _get_loop(self):
   loop = asyncio.get_running_loop()
   if self._loop is None:
self._loop = loop
   if loop is not self._loop: raise
   if not loop.is_running(): raise

   async def acquire(self):
   loop = self._get_loop()
   ...

This is what would guarantee all protections you want and would also allow to 
instantiate `asyncio.Lock` in class constructors, simplifying code.

[issue32218] add __iter__ to enum.Flag members

[Henk-Jaap Wagenaar]

Henk-Jaap Wagenaar  added the comment:

What does aenum do and has there been any feedback on it?

To me I would see what you suggest as surprising but I don't use enums often (I 
should use them more!) so take that with a grain of salt, and also surprising 
!= wrong/not good.

[issue42400] Ubuntu tests hangs on test_ttk_guionly and test_heading_callback

[E. Paine]

E. Paine  added the comment:

Issue 42142 covers this problem. I want to get PR-23156 merged which will 
(until a better fix is found) skip tests on Ubuntu which use `wait_visibility`.

However, this is becoming more of an issue and I am worried now about the 
general stability of the tkinter graphical tests on the bots. For example, 
Victor reported issue 42370 which caused the Github Ubuntu action to fail due 
to a random ttk Spinbox problem.

[issue39573] [C API] Make PyObject an opaque structure in the limited C API

[STINNER Victor]

STINNER Victor  added the comment:

I wrote PR 23366 to revert the Py_TYPE() and Py_SIZE() changes: convert them 
back to macros to allow again "Py_TYPE(obj) = type;" and "Py_SIZE(obj) = size;" 
syntaxes.

Well, since the PEP 620 is not accepted, I prefer to revert the Py_TYPE() and 
the Py_SIZE() changes for now. We should have a wider discussion on how to 
introduce incompatible changes into the C API before being able to push more 
incompatible changes which impact a so wide range of C extension modules.

One practical problem is how to estimate the number of broken Python projects 
to decide if an incompatible change can be introduced or not. When I did early 
experiment before merging the PR 20290, it seems like only a minority of C 
extensions rely on "Py_TYPE(obj) = type;" syntax. It's a common pattern to 
define a type statically. Pseudo-code:

---
PyTypeObject MyType = {...};

PyInit_MyExtension(...)
{
   Py_TYPE() = ...;
   PyType_Ready();
   ...
}
---

"Py_TYPE() = ...;" is required since some C compilers don't support 
setting ob_type directly in the MyType static declaration. The type must be set 
at runtime.

Also I considered that the change is trivial enough to be accepable. Well, I 
was wrong, and that's why I'm not proposing to revert thes changes.

About the rationale for introducing C API incompatible changes, see the PEP 620.

[issue15263] Guard against invalid file handles in os functions

[Eryk Sun]

Eryk Sun  added the comment:

> I don't see any _Py_VerifyFd in the code, is this out of date?

Yes, this issue is out of date. The underlying issue is that the C runtime in 
Windows automatically checks various parameters and calls a registered handler 
for invalid parameters, for which the default handler terminates the process. 
Python 3.5+ uses a new C runtime (ucrt), which supports setting a handler for 
just the current thread, so this issue is addressed more generally nowadays by 
the macros _Py_BEGIN_SUPPRESS_IPH and _Py_END_SUPPRESS_IPH.

Usually, it's not that the subinterpreter work introduces new leak, but makes 
old leak suddenly visible.

The create_filter() leak was introduced way earlier:

commit 9b99747386b690007027c3be2a5d7cfe3d3634f5
Author: Nick Coghlan 
Date:   Mon Jan 8 12:45:02 2018 +1000

bpo-31975 (PEP 565): Show DeprecationWarning in __main__ (GH-4458)

It's a minor leak since the create_filter() function is called exactly 5 times 
at startup. It's a leak of 5 strong references, it's not a big deal :-)
