The result of variable "a" should be b'30\x11\x00\x00' not b'0\x11\x00\x00' .
>>> import struct
>>> a = struct.pack(">> print(a)
b'0\x11\x00\x00'

New submission from Jimmy Retzlaff <[EMAIL PROTECTED]>:
I'm seeing the same symptoms that are described in issue 1543 with the
2.6b3 MSIs. Namely, when you run one of the MSIs (either 32-bit or
64-bit) then the other will refuse to install. This is on XP Pro x64 SP2.
python-3.0b3.msi

Works great on 2.6rc1. Thanks!

Just found Guido mentioned LibCST. Here is a quick overview:
1. LibCST is an open source Python concrete syntax tree parser. It provides a
CST looks like and feel like AST.
2. It's built by Instagram for linter and refactoring tools (exact use cases

replacing python38._pth by python._pth does fix it.

Problem:
"RuntimeError: Event loop stopped before Future completed." throws when calling
run_until_complete().
We investigate and find out some orphan futures stay in the event loop before
we run another run_until_complete(another_async_func()).
New submission from Jimmy Lai :
`ensure_future` converts the input as future if it's not already a future.
The condition is the following:
if futures.isfuture(coro_or_future):
...
elif coroutines.iscoroutine(coro_or_future):
...
elif inspect.isawaitable(coro_or_future):

@vstinner Thanks for the new benchmark, it provides more detailed wins:
It's 1.64x faster for future object and 1.23x faster for non-future object.

@pitrou This change is part of optimization for asyncio.gather().
gather -> ensure_future -> isfuture/iscoroutine/isawaitable
We need C implementation for all those function to make gather really efficient
for large scale application (e.g. Instagram)

Jimmy Lai added the comment:
@pitrou We'll measure the wins of gather when we implement it in C. Before
that, we need to get all helpers ready in C.

@vstinner
In general, we would like to make all asyncio common functions efficient with C
implementation because CPython asyncio overhead is very expensive.
In our application, overall it costs about 10% global CPU instructions after we
used UVLoop (it's
