Yeah I have to agree at this point, from a naive point of view it looks
awesome, but its just as bad as loosing gil guarantees.

The standard contextmanager decorator produces a wrapper that itself can be
used as a decorator
```
@contextmanager
def some_context():
...
yield
@some_context()
def some_function():
# we are inside a with some_context() now.

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

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.

Its not possible to have it both ways. Also it stinks too much of trying to
guess.
The root of your issue is you want a normal MagicMock not an AsyncMock. Its the
automatic behavior of patch to pick AsyncMock vs MagicMock that is the heart of
your issue

At Facebook and Instagram we have large interconnected codebases without clear
boundaries of ownership. As we move more and more services to utilize asyncio
we are finding that once blocking (but fast) code paths, are now cropping up

New submission from Jason Fried :
wait is a very overloaded word in asyncio. Events and Conditions are not
consistent with the rest of asyncio.
Why don't Future and Task have wait() methods? well because they are awaitable
Some subjective reasoning:
Every time I go to use one of

Removed Condition from this request, because it has an __await__ method for
supporting the the deprecated pattern
with async cond:
I'll open a different bug, for Condition behavior for 3.9 when we can remove
the deprecated pattern.

In 3.9 we can remove the deprecated pattern for accepting __enter__ and
__exit__ for locks. This will free up __await__ for Condition to use for
replacing .wait() which is wart from before awaitables.
My new proposed behavior is
await cond
which would be

For loops not supporting this throwing NotImplmentedError from the method to
enable reentrancy seems appropriate.

That may not be practical for large code bases in transition to asyncio. The

Looking at the typing Module docs in the section for ByteString
This type represents the types bytes, bytearray, and memoryview.
But collections.abc.ByteString does not have memoryview registered.
Is it because memoryview doesn't support .
New submission from Jason Fried:
With large tar file extracts I noticed that tarfile was slower than it should
be. Seems in linux that for large files (10MB) truncate is not always a free
operation even when it should be a no-op. ex: File is already 10mb seek to end
and truncate.

The default of 16k while good for memory usage it is not well suited for all
cases. if we increased this to 4MB we saw a pretty large improvement to tar
file creation and extraction on linux servers.
For a 1gb tar file containing 1024 random files each of 10MB
