Hello all,
I have implemented an initial version of PEP 393 -- "Flexible String
Representation" as part of my Google Summer of Code project. My patch
is hosted as a repository on bitbucket [1] and I created a related
issue on the bug tracker [2]. I posted documentation for the current
state of the development in the wiki [3].
Current tests show a potential reduction of memory by about 20% and
CPU by 50% for a join micro benchmark. Starting a new interpreter
still causes 3244 calls to create compatibility Py_UNICODE
representations, 263 strings are created using the old API while 62719
are created using the new API. More measurements are on the wiki page
[3].
If there is interest, I would like to continue working on the patch
with the goal of getting it into Python 3.3. Any and all feedback is
welcome.
Regards,
Torsten
