reading yaml from socket may block in determine_encoding()

[socketpair@…]

The problem here:

reader.py:

determine_encoding():

1. call self.update_raw() until receive needed length. Suppose it receives all data from the kernel buffer, i.e. in my case - full document (--- xxxxxxxx\n...\n) self.eof will not be set
2. call update(1) which have the code: if not self.eof:

self.update_raw()

as the self.eof is False (we never receive empty string) we will hang for any (uneeded here) data.

############################### How to fix: just remove

---

if not self.eof:

self.update_raw()

for files - is not sensible, because reading plain file never block.
