[issue26292] Raw I/O writelines() broken for non-blocking I/O

[Martin Panter]

Martin Panter added the comment:

Here is a patch documenting that RawIOBase.writelines() is undefined for partial writes and blocking errors, as mentioned in (1) above.

The alternative of requiring write() to be retried would IMO be unfair to existing writelines() implementations. It also seems out of place considering we don’t even have a RawIOBase.writeexactly() type of method.
