We don't know how many possible values there will be, or whether they will be affected by environmental settings. Developers will not always know what sort of systems users will have, but they can indicate (with a ratio) where in the range (slow+safe):(fast+risky) they rate this particular flush. Before this discussion, I knew about sync, but had not paid attention even to datasync, let alone fullsync. I have no idea which additional options may be relevant in the future, or on smaller devices or other storage media. I do expect specific intermediate values (such as 0.3) to be interpreted differently on a laptop than on a desktop. -jJ _______________________________________________ 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
