Causing perfectly good Python 2 applications to degrade in performance is bad,
even if something else is available.
This should be fixed as a regression.

As far as I understand, this is not a regression. I don't think the cStringIO
code has changed in years.

Ok, reading more carefully, it's not a regression. But it's certainly a bug,
and should be fixed.

Right. The patch looks straightforward, but I'm not familiar with the
cStringIO code. Could you take a look?

Fair enough, but there is a great deal of existing code that already
uses cStringIO.

New submission from Patrick Strawderman patr...@zope.com:
cStringIO.StringO's seek method has O(n) characteristics in certain,
albeit pathological, cases, while the pure Python implementation and
cStringIO.StringI's seek methods both execute in constant time in all cases.

I'm changing the versions to just 2.7 (though I'm not sure this can be
considered a bug fix), since StringIO is reimplemented as part of io in 3.x.

Antoine Pitrou pit...@free.fr added the comment:
I don't think there's much point in fixing this. 2.7 users can use io.BytesIO,
which is a fast type implemented in C.
