[issue42202] Optimize function annotation

[Yurii Karabas]

Yurii Karabas <1998uri...@gmail.com> added the comment:

> func.__annotations__ =  ('x', 'int', 'z', 'float', 'return', 'Hoge') is much 
> better because:

Inada, I totally agree with you. Sorry, I didn't realize all pitfalls with 
extra field to codeobject.

New implementation with annotations representation as a single tuple doesn't 
require a lot to change to the existing codebase. And I have already done it.

I rerun all benchmarks and there is no performance degradation in a case when 
the function doesn't have annotations and it's more than 2 times faster when 
the function has annotations.

Benchmark results:

[issue42398] Race condition in "make regen-all" when running jobs in parallel

[STINNER Victor]

New submission from STINNER Victor :

When building the Fedora package of Python 3.10, *sometimes* the "make 
regen-all" fail to build with errors like:

/builddir/build/BUILD/Python-3.9.0/Modules/_weakref.c:131:5: error: 
'_WEAKREF_GETWEAKREFCOUNT_METHODDEF' undeclared here (not in a function)
  131 | _WEAKREF_GETWEAKREFCOUNT_METHODDEF
  | ^~
/builddir/build/BUILD/Python-3.9.0/Modules/_weakref.c:132:5: error: expected 
'}' before '_WEAKREF__REMOVE_DEAD_WEAKREF_METHODDEF'
  132 | _WEAKREF__REMOVE_DEAD_WEAKREF_METHODDEF
  | ^~~


Example: https://src.fedoraproject.org/rpms/python3.9/pull-request/40

The _WEAKREF_GETWEAKREFCOUNT_METHODDEF macro is defined by 
Modules/clinic/_weakref.c.h which is included by Modules/_weakref.c (at line 
13).

It seems like while Modules/_weakref.o was being built, 
Modules/clinic/_weakref.c.h was being generated "at the same time".

The "make regen-all" command runs "make clinic" and "make regen-importlib" 
targets:

* "make regen-importlib" builds Modules/_weakref.o from Modules/_weakref.c and  
Modules/clinic/_weakref.c.h

* "make clinic" always rewrites "Modules/clinic/_weakref.c.h" file


On Fedora, packages are built using MAKEFLAGS="-j" where  is a number, 
like "-j4". Since there is no dependency between "clinic" and "regen-importlib" 
targets, these two targets *can* be run in parallel.

It seems like "make clinic" always rewrites *all* generated files and the half 
of writes are *not* atomic.


Attached PR makes all writes of clinic.py atomic *and* also avoids modifying 
the file modification file if the content does not change, as done in other 
"make regen-all" targets (using Tools/scripts/update_file.py).

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

[Andrew Svetlov]

Andrew Svetlov  added the comment:

My initial thought was protecting the Lock (and other primitives) creation when 
a loop is not running.

Yuri insists that Lock can be created without a loop. Technically it is 
possible, sure.
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).

Thus, the global scoped lock object still looks suspicious in my eyes.
The lock's lifecycle should be closer than the lifecycle of the loop, isn't it? 
I know, asyncio.Lock() can safely live after the loop closing but should we 
encourage this style? There are many other asyncio objects like HTTP clients 
and DB drivers that should be closed before the loop finishing for graceful 
closing TCP transports etc.

Another thing to consider is: whether to cache a loop inside a lock;  whether 
to add a check when the lock is used by two loops?

I think for the last question the answer is "yes". I recall many questions and 
bug reports on StackOverflow and aiohttp bug tracker when people use the 
multithreaded model for some reason and tries to get access to a shared object 
from different threads that executes each own loop.

The check becomes extremely important for synchronization primitives like 
asyncio.Lock class; threading.Lock is supposed to be shared between threads and 
users can apply the same pattern for asyncio.Lock by oversight.
Also, supporting global asyncio.Lock instances increase the chance that the 
lock is used by different loops.

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 :-)

[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.

Upon closer investigation something or someone has replaces and monkey patched

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

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(&MyType) = ...;
   PyType_Ready(&MyType);
   ...
}
---

"Py_TYPE(&MyType) = ...;" 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.

[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.

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.

[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.

[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

[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.
