[New-bugs-announce] [issue25608] ascynio readexactly() should raise ValueError if passed length <= 0 in argument

[Марк Коренберг]

New submission from Марк Коренберг:

ascynio readexactly() should raise ValueError if passed length <= 0 in argument.

Now, it return empty string, which is just error hiding. Why not to raise ValueError ? 

Returning empty string is error prone. This behaviour was not changed since initial commit of asyncio, so probably was not done intentionally.
