Subject: Remove all the "assert(len>0)" which forbade zero-length writes across the
X-Git-Url: https://git.distorted.org.uk/u/mdw/putty/commitdiff_plain/bfa5400d3e166e1acc25dbe0b7f1fdf74b272568?hp=bfa5400d3e166e1acc25dbe0b7f1fdf74b272568

Remove all the "assert(len>0)" which forbade zero-length writes across the
from_backend() interface, after having made all implementations safe against
being called with len==0 and possibly-NULL/undefined "data".

(This includes making misc.c:bufchain_add() more robust in this area.)

Assertion was originally added 2002-03-01; e.g., see plink.c:1.53 [r1571].

I believe this now shouldn't break anything.

This should hopefully make `ppk-empty-comment' finally GO AWAY. (Tested
with Unix PuTTY.)
