[New-bugs-announce] [issue25752] asyncio.readline - add customizable line separator

[Марк Коренберг]

New submission from Марк Коренберг:

In Python3.5 asyncio.StreamReader.readline() can separate lines only by b'\n'. For some task, I want actually "read until separator", where separator is another byte.

Since I cannot create pull-request, I will write just here what I want:

@coroutine
def readline(self, separator=b'\n'):
    if not isinstance(separator, bytes) or len(separator) != 1:
        raise ValueError(separator)
    ....
    ichar = self._buffer.find(separator)
    ....
