This looks fine to me, however, I wonder, why this approach was ever
taken? The sys.setdefaultencoding is available in all versions of Python
ever supported by FreeIPA.

Is it possible we're missing something here? Or was this option simply
overlooked?


sys.setdefaultencoding() is not available unless you use a hack and
reload the sys module. The function is hidden for a very good reason. It
can and will break internal assumption as well as libraries in bad, hard
to detect ways. For example it wreaks havoc on hashing for dicts and
sets.

The blog posting
https://anonbadger.wordpress.com/2015/06/16/why-sys-setdefaultencoding-will-break-code/

explains the problem in much greater detail.


Tomáši, does this answer your question?



Not really, I was more curious as to why the current, more complex
solution using the C extension was ever preferred over pure python version.


Updated patch attached.


Patch works fine, ACK.

Is it possible we're missing something here? Or was this option simply

There is more history to it and it is mostly ugly:
https://bugzilla.redhat.com/show_bug.cgi?id=243541


What is actually ugly is badly written code which assumes a specific 
encoding anywhere instead of using an encoding appropriate in the given 
context. Rather than working around it using hacks such as changing the 
default encoding, the preferrable solution should be to fix the badly 
written code itself (which is not always easy, as is the case with IPA).

I do agree with you in general but this case is sufficiently different
enough to warrant what we have in place.
