Raymond Hettinger <raymond.hettin...@gmail.com> added the comment: ISTM that a discussion on python-dev would be of value here. Iterators are a protocol, not a class; hence, the effort to make them all picklable is potentially endless. The effort would also always be incomplete because some iterators are difficult or inconvenient to pickle (esp. those with inputs from local or temporary resources).
Experience with SQL hasn't shown a need to save partially consumed cursors and my experience with iterators indicates that the need for pickling would be rare or that is would distract from better solutions (perhaps message based or somesuch). The size of this patch is a hint that the idea is not a minor change and that it would add a maintenance burden. What is far from clear is whether it would have value for any real-world problems. ---------- nosy: +rhettinger _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue14288> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
