New submission from Antoine Pitrou <[EMAIL PROTECTED]>:
In py3k, PyUnicode_Join inherits some complexity from the 2.x days.
However, it seems some of the precautions taken there may not be needed
anymore. Witness the following comment:
/* Grrrr. A codec may be invoked to convert str objects to
* Unicode, and so it's possible to call back into Python code
* during PyUnicode_FromObject(), and so it's possible for a sick
* codec to change the size of fseq (if seq is a list). Therefore
* we have to keep refetching the size -- can't assume seqlen
* is invariant.
*/
Perhaps it would also allow to preallocate the target buffer all at once
(like bytes.join does) rather than resize it incrementally.
Marc-Andre, what do you think?
