As an exercise in using the new set C API, I've replaced the "interned" dictionary in stringobject.c with a set. Surprisingly, what I thought would be a simple exercise, took several hours to implement and debug. Two problems are worth mentioning:
1. I had to add a function to setobject.h to retrieve a pointer to an object stored in a set. I could not find a way to do it using current API (short of iterating through the set of course). 2. I had to change the PyString_Fini() and PySet_Fini() in Py_Finalize() because cleaning "interned" set cannot be done after the set module is finalized. If there is any interest, I will submit a patch, but it does not seem to affect performance in any meaningful way. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
