Ulrich Petri <[email protected]> added the comment:
This change breaks (probably unsupported) uses of the logging module (esp. in
combination with structlog) where non-string objects are passed through the
.format() and .emit() calls.
Previously it was possible to set the terminator attribute to None (and then
handling that case in a custom 'stream' implementation), which now breaks with
a TypeError due to the concatenation.
In case anyone else runs into this (however unlikely that is). A workaround is
to set the .terminator to something like this:
class ConcatenableNothing:
def __radd__(self, other):
return other
