I concur with others who think this should not be removed. It's used in different stdlib and third party modules' test suites. I see tempfile.mktemp() very similar to test.support.find_unused_port() and os.path.exists/isfile/isdir functions: they are all subject to race conditions but still they are widely used and have reason to exist (practicality beats purity). I suggest turning the doc deprecation into a note:: or warning::, so that extra visibility is maintained. Because the use case is legitimate and many fs-related APIs such as this one are inevitably racy, I lean more towards a note:: rather than a warning:: though, and we could probably do the same for os.path.is* functions. @Sebastian > If there are valid use cases for mktemp(), I recommend renaming > it to mkname_unsafe() or something equally obvious. I'm -1 about adding an alias (there should be one and preferably only one way to do it). Also mkstemp() and mkdtemp() are somewhat poorly named IMO, but I wouldn't add an alias for them either. -- Giampaolo - http://grodola.blogspot.com _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
