#7990 closed (fixed)

serializers should use StringIO and not cStringIO

Reported by: anonymous Owned by: nobody
Component: Core (Other) Version: master
Severity: Keywords: cstringio serializers unicode
Cc: Triage Stage: Accepted
Has patch: no Needs documentation: no
Needs tests: no Patch needs improvement: no
Easy pickings: UI/UX:


there is a slight difference between cStringIO and StringIO which makes cStringIO unusable for unicode data:

>>> import StringIO
>>> import cStringIO
>>> s1 = StringIO.StringIO(u'unicode text')
>>> s2 = cStringIO.StringIO(u'unicode text')
u'unicode text'
'u\x00\x00\x00n\x00\x00\x00i\x00\x00\x00c\x00\x00\x00o\x00\x00\x00d\x00\x00\x00e\x00\x00\x00 \x00\x00\x00t\x00\x00\x00e\x00\x00\x00x\x00\x00\x00t\x00\x00\x00'

This makes serializers such as json or yaml unusable for unicode data.

The particular problem reported here is only present in python 2.3 and 2.4. However, more significantly, even in python 2.5, cStringIO cannot handle non-ASCII unicode strings. This is a documented feature of the module, so for that reason, we should change it.
