New submission from Ryan Govostes <rgovos...@gmail.com>:
The documentation for the io.BufferedRWPair class gives this warning: > BufferedRWPair does not attempt to synchronize accesses to its underlying raw > streams. You should not pass it the same object as reader and writer; use > BufferedRandom instead. I have a hard time understanding what this warning is trying to tell me. 1. What does it mean to "synchronize accesses"? 2. Why can't I pass the same object as reader and writer? The docstring in _pyio.py says, "This is typically used with a socket or two-way pipe." 3. How does BufferedRandom, which adds the seek() and tell() interfaces, address the issue of "synchroniz[ing] accesses"? Is synchronization automatic? What does this do for sockets or pipes which cannot seek? ---------- assignee: docs@python components: Documentation messages: 355404 nosy: docs@python, rgov priority: normal severity: normal status: open title: io.BufferedRWPair doc warning may need clarification type: behavior versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38595> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
