New submission from Nathaniel Smith: DeprecationWarning and PendingDeprecationWarning are invisible by default. The rationale for this is that they are only useful to people who are writing code, so they should not be shown to end-users who are merely running code.
If someone is typing stuff into the interactive REPL, though, and the code they type uses some deprecated functionality, then we should actually show them this warning. We know that the author is sitting right there. And they're probably going to take whatever they tested interactively and move it into a more permanent form and ugh. This problem is particularly acute for packages that are primarily used through the interactive prompt, like numpy. I am tired of getting bugs like this: https://github.com/numpy/numpy/issues/5919 The solution is simple: when entering interactive mode, the REPL should do something like: warnings.filterwarnings("default", category=DeprecationWarning, module="__main__") warnings.filterwarnings("default", category=PendingDeprecationWarning, module="__main__") ---------- messages: 244147 nosy: njs priority: normal severity: normal status: open title: DeprecationWarnings should be visible by default in the interactive REPL type: enhancement _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue24294> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
