[New-bugs-announce] [issue12807] Optimizations for {bytearray, bytes, unicode}.strip()

[John O'Connor]

New submission from John O'Connor <tehjcon at gmail.com>:

bytearray() is using a less efficient implementation of split() than its similar friends bytes and unicode.

I added a couple extra checks to return early in {bytes,unicode} split().
 - if length is 0
 - if left strip removed all bytes

Looking at just how similar these 3 implementations are I feel that we could also unify/generalize them into one generic helper implementation and leave the object marshaling up to the type specific methods.
