[issue34725] Py_GetProgramFullPath() odd behaviour in Windows

[Steve Dower]

Steve Dower  added the comment:

The next releases of 3.7 and 3.8 will include _Py_SetProgramFullPath() 
functions for embedders to set the eventual value of sys.executable before 
calling Py_Initialize(). It's undocumented and not guaranteed stable (and 
indeed, it looks like Victor is already working on another patch that may see 
it removed before it's ever released), but it's in now as a workaround for the 
cases that need it.

[issue35270] Cmd.complete does not handle cmd=None

[daniel hahler]

New submission from daniel hahler :

When `parseline` returns `None` for `cmd` (like pdb++ might cause it when 
changing a cmd "disable" to "!disable"), the following will cause a TypeError:

> compfunc = getattr(self, 'complete_' + cmd)

"None" should be also forwarded to "completedefault", just like cmd="".

[issue35269] A possible segfault involving a newly-created coroutine

[Zackery Spytz]

New submission from Zackery Spytz :

If compute_cr_origin() fails in PyCoro_New(), coro->cr_origin won't be 
initialized. This will cause a crash during the coroutine's deallocation.

I'll create a PR for this issue.

[issue35268] Windows asyncio reading continously stdin and stdout Stockfish

[Cezary Wagner]

Cezary Wagner  added the comment:

It looks like StremReader.read() not work and StremReader.readline() in Windows 
or I am not understand documentation.

https://docs.python.org/3/library/asyncio-stream.html

coroutine read(n=-1)

Read up to n bytes. If n is not provided, or set to -1, read until EOF and 
return all read bytes.

If EOF was received and the internal buffer is empty, return an empty bytes 
object.



coroutine readline()

Read one line, where “line” is a sequence of bytes ending with \n.

If EOF is received and \n was not found, the method returns partially read 
data.

If EOF is received and the internal buffer is empty, return an empty bytes 
object.

[issue35268] Windows asyncio reading continously stdin and stdout Stockfish

[Cezary Wagner]

New submission from Cezary Wagner :

I have some problems with asyncio on Windows - it block where it should go.
Documentation shows that it should work: 
https://docs.python.org/3/library/asyncio-stream.html -> StreamReader should 
return something.

See 1st example:

import asyncio

import sys


async def run_stockfish():
STOCKFISH_PATH = r'C:\root\chess\stockfish\stockfish 
9\stockfish_9_x64_bmi2.exe'

stockfish = await asyncio.subprocess.create_subprocess_exec(
STOCKFISH_PATH,
stdin=asyncio.subprocess.PIPE,
stdout=asyncio.subprocess.PIPE,
stderr=asyncio.subprocess.PIPE)

stockfish.stdin.write('uci'.encode())

while True:
# BUG? - blocks at this line - no output
line = await stockfish.stdout.read()
print(line)

await stockfish.wait()


if sys.platform == "win32":
asyncio.set_event_loop_policy(
asyncio.WindowsProactorEventLoopPolicy())

asyncio.run(run_stockfish(), debug=True)

1st output (nothing):
Python 3.7.1 (v3.7.1:260ec2c36a, Oct 20 2018, 14:57:15) [MSC v.1915 64 bit 
(AMD64)] on win32
runfile('C:/Users/Cezary 
Wagner/PycharmProjects/stockfish-proxy/sandbox/async_proxy/s01_async_stockfish.py',
 wdir='C:/Users/Cezary 
Wagner/PycharmProjects/stockfish-proxy/sandbox/async_proxy')

2nd example:

import asyncio

import sys


async def run_stockfish():
STOCKFISH_PATH = r'C:\root\chess\stockfish\stockfish 
9\stockfish_9_x64_bmi2.exe'

stockfish = await asyncio.subprocess.create_subprocess_exec(
STOCKFISH_PATH,
stdin=asyncio.subprocess.PIPE,
stdout=asyncio.subprocess.PIPE,
stderr=asyncio.subprocess.PIPE)

stockfish.stdin.write('uci'.encode())

while True:
# BUG? - blocks at this line
line = await stockfish.stdout.readline()
print(line)

await stockfish.wait()


if sys.platform == "win32":
asyncio.set_event_loop_policy(
asyncio.WindowsProactorEventLoopPolicy())

asyncio.run(run_stockfish(), debug=True)

2nd output is little better (first line is read):
Python 3.7.1 (v3.7.1:260ec2c36a, Oct 20 2018, 14:57:15) [MSC v.1915 64 bit 
(AMD64)] on win32
runfile('C:/Users/Cezary 
Wagner/PycharmProjects/stockfish-proxy/sandbox/async_proxy/s01_async_stockfish.py',
 wdir='C:/Users/Cezary 
Wagner/PycharmProjects/stockfish-proxy/sandbox/async_proxy')

INADA-san: do you prefer to raise an exception? If yes, can we ensure that
an exception will always be raised? See my 2 examples.
